Forward-Looking Statements

The disclosures set forth in this Report are qualified by Part I, Item 1A. Risk Factors and the section captioned “Forward Looking Statements” in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this Report and other cautionary statements set forth elsewhere in this Report.

Explanatory Note

In November 2020, the Securities and Exchange Commission (the “SEC”) enacted changes to a number of financial disclosure requirements in Regulation S-K aiming to streamline and reduce duplicative disclosure by eliminating certain prescribed information in favor of a more principles-based approach (collectively, the “November 2020 Amendments”). The November 2020 Amendments were published in the Federal Register on January 11, 2021 and became effective on February 10, 2021. Under the November 2020 Amendments, we are permitted to provide disclosure consistent with the recent amendments at any time after February 10, 2021. We have elected to provide certain disclosure consistent with the November 2020 Amendments throughout this Report.

PART I

Item 1. Business.

Overview

SouthState Corporation (“We,” “Our,” “SSC” or the “Company”) is a financial holding company headquartered in Winter Haven, Florida, that incorporated under the laws of South Carolina in 1985. We provide a wide range of banking services and products to our customers through our wholly owned bank subsidiary, SouthState Bank, National Association (the “Bank”), a national banking association, from our headquarters branch in Winter Haven, Florida and, as of December 31, 2021, a 281-branch network located throughout Florida, South Carolina, Alabama, Georgia, North Carolina, and Virginia. In addition, the Company operates SSB Insurance Corp., a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code. We do not engage in any significant operations other than the ownership of our banking subsidiary.

Through the Bank, we operate a correspondent banking and capital markets service division for over 1,060 small and medium sized community financial institutions throughout the United States. Based primarily in Atlanta, Georgia and Birmingham, Alabama, this division earns commissions on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities. The Bank also operates SouthState Advisory, Inc., a wholly owned registered investment advisor, which offers support to the Bank’s Wealth line of business.

In February 2021, the Bank completed its acquisition of Duncan-Williams, Inc., a full-service broker dealer that is being integrated into our correspondent division due to the complementary nature of its capital markets business (“DWI”). The Bank also owns CBI Holding Company, LLC (“CBI”), which in turn owns Corporate Billing, LLC (“Corporate Billing”), a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide.

At December 31, 2021, we had approximately $42.0 billion in assets, $23.9 billion in loans, $35.1 billion in deposits, $4.8 billion in shareholders’ equity, and a market capitalization of approximately $5.6 billion.

On June 7, 2020, the Company acquired all of the outstanding common stock of CenterState Bank Corporation of Winter Haven, Florida (“CSFL”), the holding company for CenterState Bank, N.A. (“CSB”), in a stock transaction. Pursuant to an Agreement and Plan of Merger, (i) CSFL merged with and into the Company, with the Company continuing as the surviving corporation (the “CenterState Merger”), and (ii) immediately following the CenterState Merger, South State Bank, a South Carolina banking corporation and wholly owned bank subsidiary of the Company merged with and into CenterState Bank, National Association (“CSB”), a national banking association and wholly owned bank subsidiary of CSFL, with CSB continuing as the surviving bank (the “CenterState Bank Merger”). In connection with the CenterState Bank Merger, CSB changed its name to “South State Bank, National Association,” and

in November 2021, the Bank changed its name to SouthState Bank, National Association.

On July 22, 2021, the Company entered into an Agreement and Plan of Merger (the “ACBI Merger Agreement”) with Atlantic Capital Bancshares, Inc. of Atlanta, Georgia (“ACBI”), the banking holding company for Atlantic Capital Bank, National Association (“Atlantic Capital”), in a stock transaction. Pursuant to the ACBI Merger Agreement, (i) ACBI will merge with and into the Company, with the Company continuing as the surviving corporation (the “ACBI Merger”), and (ii) immediately following the ACBI Merger, and subject to it occurring, Atlantic Capital will merge with and into the Bank (the “ACB Bank Merger” and collectively with the ACBI Merger, the “Merger”). All required regulatory approvals to complete the ACBI merger and the ACB Bank merger have been received. The Merger is expected to close in the first quarter of 2022.

Our principal executive offices are located at, and our mailing address is, 1101 First Street South, Suite 202, Winter Haven, Florida 33880. Our telephone number is (863) 293-4710.

Our revenue is primarily derived from interest on, and fees received in connection with, real estate and other loans, interest and dividends from investment securities and short-term investments, commissions on bond sales, fees from hedging services, and gains from the sale of residential mortgage loans. The principal sources of funds for our lending activities are customer deposits, repayment of loans, and the sale and maturity of investment securities. Our principal expenses are interest paid on deposits and operating and general administrative expenses.

As is the case with banking institutions generally, our operations are materially and significantly influenced by the real estate market, general economic conditions, and by the tax, monetary and fiscal policies of the U.S. and state government and regulatory agencies, including the Federal Reserve. Deposit flows and costs of funds are influenced by interest rates on competing investments and general market rates of interest. Lending activities are affected by the demand for financing of real estate and other types of loans, which in turn is affected by the interest rates at which such financing may be offered and other factors affecting local demand and availability of funds, including tax rates and regulatory structure. We face strong competition in the attraction of deposits (our primary source of lendable funds) and in the origination of loans. See “Competition.”

Products and Services

Lending Activities

Our loan portfolio includes commercial real estate loans, residential real estate loans, commercial and industrial loans and consumer loans. The principal risk associated with each category of loans we make is the creditworthiness of the borrower. Borrower creditworthiness is affected by general economic conditions and the attributes of the borrower and the borrower’s market or industry. Attributes of the relevant business market or industry include the competitive environment, customer and supplier availability, the threat of substitutes and barriers to entry and exit.

Commercial Real Estate Loans. As of December 31, 2021, $14.4 billion, or 60%, of our loan portfolio consisted of loans secured by commercial real estate (including owner occupied and non-owner occupied commercial real estate and construction and land development lending). We offer construction financing, acquisition financing or refinancing of properties, commercial lines of credit and other loans that are secured by commercial real estate.

Residential Real Estate Loans. As of December 31, 2021, $4.8 billion, or 20%, of our loan portfolio consisted of residential real estate loans including home equity loans. We provide one-to-four family residential real estate loans with terms ranging from 10 to 30 years, with either fixed or adjustable interest rates and home equity lines. It is not our normal business practice to originate subprime loans. Our closed-end first lien loans are for purposes of property purchased, or for refinancing existing loans. The majority of our loans are owner occupied, full documentation loans.

Commercial and Industrial Loans (“C&I”). As of December 31, 2021, $3.8 billion, or 16%, of our loan portfolio consisted of commercial and industrial loans. Our C&I loans include lines of credit, acquisition finance credit facilities and other types of commercial credit, and typically have maturities of five years or less.

Other Consumer Loans. As of December 31, 2021, $928 million, or 4%, of our loan portfolio consisted of other types of consumer loans. We offer consumer loans to our customers for personal, family and household purposes, including auto, boat and personal installment loans.

We believe we have a strong team of consumer and commercial bankers to execute on our client-centered, relationship-driven banking model. Our commercial banking team consists of experienced professionals that use an advisory approach that emphasizes understanding each client’s business and offering a broad suite of loan, deposit and treasury management products and services. Our consumer banking team consists of experienced professionals that focus on knowing their individual clients in order to best meet their financial needs, offering a full complement of loan, deposit and online banking solutions. We generally do business with clients located in the areas served by our branches, and we focus our marketing efforts on these areas.

Deposit Products, Treasury Services and Other Funding Sources

We offer our customers a variety of deposit products and services, including checking accounts, savings accounts, money market accounts, other deposit accounts and treasury and merchant services, through multiple channels, including our extensive network of 281 full-service branches, as of December 31, 2021, and our online, mobile and telephone banking platforms. As of December 31, 2021, our deposit portfolio was comprised of 33% noninterest-bearing deposits and 67% interest bearing deposits. We intend to continue our efforts to provide funding for our business from customer relationship deposits.

Deposit flows are significantly influenced by general and local economic conditions, changes in prevailing interest rates, internal pricing decisions and competition. Our deposits are primarily obtained from depositors located around our branch footprint, and we believe that we have attractive opportunities to capture additional retail and commercial deposits in our markets. In order to attract and retain deposits, we rely on providing quality service, offering a suite of retail and commercial products and services and introducing new products and services that meet our customers’ needs as they evolve.

In addition to traditional banking activities and the other products and services specified above, we provide a broad array of financial services to our customers, including debit card and mobile and funds transfer products and services, and treasury management services, including merchant services, automated clearing house services, lock-box services, remote deposit capture services and other treasury services.

Correspondent Banking

We operate a correspondent banking and capital markets business through our correspondent division of the Bank and through DWI, the Bank’s broker dealer subsidiary the Bank acquired in February 2021. Its primary revenue generating activities are related to the capital markets division which includes commissions earned on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities. Income generated related to the correspondent banking services includes spread income earned on correspondent bank deposits (i.e. federal funds purchased) and fees generated from safe-keeping activities, bond accounting services, asset/liability consulting services, international wires, clearing and corporate checking account services and other correspondent banking related services. The fees derived from the correspondent banking services are less volatile than those generated through the capital markets group. The customer base includes small to medium size financial institutions located throughout the United States.

Wealth Management

Through the Bank and SouthState Advisory, Inc., we offer wealth management and other fiduciary and private banking services targeted to affluent clients, including individuals, business owners, families and professional service companies. In addition to fiduciary and investment management fee income, we believe these services enable us to build new relationships and expand existing relationships to grow our deposits and loans. Through our wealth management line of business, we offer financial planning, retirement services and trust and investment management for affluent clients as well as clients with more modest resources. We offer a wide range of investment alternatives, including certificates of deposits, mutual funds, annuities, individual retirement accounts, money market accounts and other financial products.

Mortgage Banking

We have a mortgage line of business which originates single-family home loans and sells a majority of those mortgages into the secondary market of which the majority are sold with servicing rights retained. We also have a SBA 7(a) line of business whereby we routinely sell the government guaranteed portion of the SBA loans to investors with the unguaranteed portion of the loan and the servicing rights retained.

Acquisition Strategy

Our business growth, profitability and market share have been enhanced by engaging in strategic mergers and acquisitions either within or contiguous to our existing footprint. Our acquisition strategy focuses on banking institutions that are consistent with our guiding principles of soundness, profitability and growth and are a good fit with our culture;

| • | are strategically attractive by enhancing our footprint, allowing for cost savings and economies of scale, or providing market diversification, or otherwise may be strategically compelling;

| • | have been determined to meet our risk appetite and profile; and

| • | meet our financial criteria.

We expect to continue to assess future opportunities of financial companies using these criteria, based on market and other conditions.

Competition

Our profitability depends principally on our ability to compete effectively in the markets in which we conduct business. In the financial services industry, market demands, technological and regulatory changes and economic pressures have increased competition among banks, as well as other financial institutions. Competition may further intensify as additional companies enter the markets where we conduct business and we enter mature markets in accordance with our expansion strategy.

We experience strong competition from both bank and non-bank competitors. We compete with national banks, super-regional banks, smaller community banks, nontraditional internet based banks, credit unions, insurance companies and government sponsored entities. We also compete with other financial intermediaries and investment alternatives such as mortgage companies, credit card issuers, leasing companies, finance companies, money market mutual funds, brokerage firms, governmental and corporation bonds, and other securities firms.

We encounter strong competition in making loans and attracting deposits. We compete with other financial institutions to offer customers competitive interest rates on deposit accounts, competitive interest rates charged on loans and other credit products and reasonable service charges. In addition, we also compete based on the quality and scope of the services we provide and the convenience of our banking facilities, compared to our competitors. The larger national and super-regional banks may have significantly greater lending limits and may offer additional products. However, by emphasizing customer service and by providing a wide variety of services, we believe that our Bank has generally been able to compete successfully with our competitors, regardless of their size.

Technological advances have made it possible for our competitors, including nonbank competitors, to offer products and services that traditionally were banking products and for financial institutions and other companies to provide electronic and internet-based financial solutions, including online deposit accounts, electronic payment processing and marketplace lending, without having a physical presence where their customers are located. In addition, many of our non-bank competitors are not subject to the same extensive federal regulations that govern bank holding companies and federally insured banks. In many cases, our competitors have substantially greater resources and lending limits and offer certain services that we do not currently provide.

Legislation has continued to heighten the competitive environment in which financial institutions must conduct their business, and the potential for competition among financial institutions of all types has increased significantly. To compete, we rely upon specialized services, responsive handling of customer needs, and personal contacts by our

officers, directors, and staff.

Human Capital Management

We consider our relationship with our employees instrumental to the success of our business. We value our employees by investing in a healthy work-life balance, competitive compensation and benefit packages, and a team-oriented environment centered on professional service and open communication amongst employees. The Board of Directors oversees the strategic management of our human capital resources. The Human Resources Department’s day-to-day responsibility is managing our human capital resources.

Core Values and Culture

A strategic priority for the Company is to develop a dynamic, high performing team by, in part, facilitating a culture that increases employee engagement, devotes resources to recruiting, developing and retaining talent, and recognizes the benefits of different perspectives and experiences. The Company’s core values, an essential cultural cornerstone, sets the course by which we intend to meet this goal through our interactions with each other, our customers and our suppliers:

| • | Local Market Leadership - Our business model supports the unique character of the communities we serve and encourages decision-making by a banker that is closest to the customer.

| • | Long-Term Horizon - We think and act like owners and measure success over entire economic cycles. We prioritize soundness over short-term profitability and growth.

| • | Remarkable Experiences - We will make our customers’ lives better by anticipating their needs and responding with a sense of urgency. Each of us has the freedom and responsibility to do the right thing for our customers.

| • | Meaningful and Lasting Relationships - We communicate with candor and transparency. The relationship is more valuable than the transaction.

| • | Greater Purpose - We enable our team members to pursue their ultimate purpose in life – their personal faith, their family, their service to the community.

Because we recognize the importance of encouraging an environment that inspires our employees to act consistently with the Company’s core values, our board-level Culture Committee is charged with overseeing the internal and external culture and values messaging, implementing a program for continuing to build and retain a diverse and inclusive employee base, developing a program to recruit, train and retain the leadership and talent necessary to deliver the Company’s vision, and maintaining an employee engagement program with clear objectives.

The Company’s Code of Ethics, which also addresses conflicts of interest and self-dealing, applies to all directors, officers and employees, each of whom are expected to adhere to it in every transaction. The Company believes that each employee is entitled to work in an atmosphere and environment free of discrimination and unlawful harassment. As a result, the Company has established and communicated to all employees a reporting structure for reporting incidents of harassment or discrimination. The Company’s Whistleblower Policy provides employees, customers, vendors and others with a confidential mechanism to express concerns or complaints regarding the Company’s accounting, internal accounting controls, auditing matters, securities law compliance, or any provision of federal law relating to fraud against shareholders. Other complaints or concerns, such as relating to human resources matters, may also be submitted confidentially through the whistleblower process, and any such matters are referred to our Human Resources Department or other departments, as appropriate, for resolution.

Demographic Information

As of December 31, 2021, we had 4,929 full-time employees (compared to 5,184 as of the same date in 2020), 201 part-time employees and 4 seasonal employees. Over 97% of our employees are located in the Bank’s 6-state branch footprint of Florida (34%), South Carolina (35%), Georgia (15%), North Carolina (6%), Alabama (6%) and Virginia (1%). To date, none of our employees are covered by collective bargaining agreements, and all but one employee live in the United States. During fiscal year 2021, we hired 1,016 employees (excluding employees via merger or acquisition), and our voluntary turnover rate was 17.5%.

Diversity and Inclusion

We strive to build a powerful and diverse team of employees, knowing we are better together with our combined wisdom and intellect. With a commitment to equality, inclusion and workplace diversity, we focus on understanding, accepting, and valuing the differences between people. Our Director of Corporate Stewardship reports to the CEO and bears primary responsibility for overseeing and directing strategic initiatives related to enterprise diversity, environmental and social governance, community development, management development, and the Employee Sunshine Fund.

In 2021, the Company adopted a three-year diversity and inclusion plan built around three goals:

​ ​ |  | ​ ​ ​ ​
​ Workplace Diversity |  | ​ Recruit diverse, qualified talent representing all areas of society to add to the overall performance of the Company. ​
​ Workplace Inclusion |  | ​ Champion a culture of collaboration and acceptance that creates a comfort level for team members to be themselves and supports diverse talent retention. ​
​ Sustainability and Accountability |  | ​ Establish strategies that are sustainable and provide leaders throughout the Company with the proper tools and resources to manage and measure diversity within their respective lines of business.

In addition, in 2021 the Company formed a Diversity and Inclusion Council to provide oversight to its diversity and inclusion strategy, support the implementation of diversity and inclusion initiatives that align with our vision and core values, and promote a diverse and inclusive workplace that represents the communities in which the Bank does business. The responsibilities of this Council include, among others, identifying and addressing barriers that impact recruitment, retention and advance of diverse candidates, defining benchmarks and metrics for diverse talent acquisition and retention, and identifying and implementing diversity and inclusion training for all Company employees and directors.

In addition to our talent acquisition efforts described below, as part of our collegiate diversity and inclusion outreach efforts, we contributed to a Diversity, Equity and Inclusion (“DEI”) fund established to support the recruitment, retention, and success of diverse students, and to mitigate financial challenges experienced by underrepresented minority students that threaten their pursuit of academic achievements. Through community development and outreach, employees volunteer their time by serving as board, finance and loan committee members of various agencies and organizations, including organizations that serve minority communities, as well as minority-owned small businesses. These initiatives are overseen by our Culture Committee.

Talent Acquisition, Retention and Employee Development

Recruitment is an essential part of managing our human capital resources. We seek to hire well-qualified employees who are also a good fit for our value system. Through our commercial banking internships and management training programs, we recruit from talented, diverse pool of students from local colleges and universities. To complement other recruitment efforts, our Talent Acquisition team is committed to attending job fairs hosted by Historical Black Colleges and Universities within our footprint. Additionally, the Talent Acquisition team partners closely with regional line of business leadership to network and recruit in-market, experienced and diverse talent in metropolitan markets within our footprint who bring with them a requisite skill set, professional background and aptitude to help grow the Bank and position our teams to support and lead a larger financial institution in the future.

We encourage and support the growth and development of our employees and, when possible, seek to fill positions by promotion and transfer from within the organization. We invest in the growth and development of our employees by providing opportunities to participate in continuing education courses that are relevant to the banking industry and their job function within the Company. Our internal Corporate University offers a suite of leadership development programs to support various levels of leadership experience and expertise with graduated topics designed to engage and develop leaders by improving business acumen and offering 360 degree reviews, individual coaching opportunities and education on topics as varied as culture, communication styles and mentoring. Because the banking industry is highly regulated, we also require employees to complete annual compliance training, the classes for which are selected based on each employee’s actual job responsibilities. In 2021, employees completed on average 34 hours of Company-provided training.

Employee retention helps us operate efficiently. We believe that we offer competitive salaries, and many of our officers and key employees participate in the Company’s incentive program, which offers short-term cash incentives to reward annual performance and long-term incentives designed to reward sustainable shareholder value creation and encourage talent retention. In addition, we provide many of our employees with a comprehensive employee benefit program that includes: group life, health, dental and vision insurance; prescription benefits; flexible spending accounts; educational opportunities; an employee stock purchase plan; deferred compensation plans for officers and key employees; and a 401(k) plan with a Company match. The Company sponsors a broad leave plan that may be used for vacation, personal use and illness, and it awards paid leave based on tenure of service and title. The Company-sponsored Employee Stock Purchase Plan encourages our employees to invest in the Company by offering shares at a discounted price to participants.

Employee Health, Wellness and Safety

The safety and health of our employees is a top priority. The COVID-19 pandemic has presented a unique challenge with regard to maintaining employee safety while continuing successful operations. To promote the safety of employees performing customer-facing activities at branches and operations centers, we encourage all employees to receive vaccinations, and we require unvaccinated employees, including those who have previously tested positive for COVID-19, to wear face coverings when not in private offices or cubicles unless required otherwise by a local ordinance or mandate. Further, we encourage all employees to maintain social distance as much as possible regardless of vaccination status. While branch employees were on-site and lobbies were open for either limited or full hours generally during 2021, through teamwork and the adaptability of our management and staff, we remain flexible to close lobbies or move to drive-thru services only in situations where we do not have sufficient employees to open, staff and operate a branch during normal business hours.

Currently, 41% of our employees continue to work effectively from remote locations; however, we continue to explore safe and effective ways to bring non-branch employees that traditionally work in an office back to their respective offices. We have asked employees not to come to work when they experience signs or symptoms of a possible COVID-19 illness, and we provide Company paid time off to cover compensation during such absences to

Table of Contents

employees that (i) have been fully vaccinated within five months (Pfizer vaccine) or two months (Johnson and Johnson vaccine) of the positive diagnosis, (ii) have obtained a vaccination booster at least two weeks prior to the positive diagnosis, (iii) have tested positive for COVID-19 and (iv) are not eligible to work remotely. Depending on the nature of an employee’s responsibilities, we continue to offer our employees flexibility to perform their responsibilities due to their changing needs in light of the pandemic (i.e., challenges posed by a lack of childcare, virtual school or caring for family members). Because our employees’ needs change as the country’s pandemic response evolves, we continue to evaluate the changing COVID-19 landscape and consider processes that reduce the risk to our employees, customers and vendors while continuing to provide essential banking services.

Oversight of Environmental, Social and Governance Issues

The Governance and Nominating Committee of the Company’s Board of Directors oversees the Company’s current and emerging environmental, social and governance matters. In 2021, the Company issued its inaugural Corporate Social Responsibility Report which highlights the Company’s environmental, social and governance initiatives, including the Company’s commitment to: building vibrant communities where we operate and where our customers live and work; fostering a strong culture that supports and encourages a diverse and inclusive workforce; promoting the highest ethical standards and acting as good stewards; and being environmentally resourceful as we support efficient and sustainable practices. Our commitment to our communities, colleagues, corporate stewardship and the environment will inform our Company’s actions as we strive to meet our vision: investing in the entrepreneurial spirit, pursuing excellence, and inspiring a greater purpose. A copy of the Company’s 2021 Corporate Social Responsibility Report is available on the Bank’s website at 2021 Corporate Social Responsibility Report (https://www.southstatebank.com/global/about/corporate-stewardship).

Effect of Governmental Policies

Our earnings and business are and will be affected by the policies of various regulatory authorities of the United States, especially the Federal Reserve. The Federal Reserve, among other things, seeks to influence interest rates and the supply of money and credit within the United States. Among the traditional methods that have been used to achieve this objective are open market operations in U.S. government securities, changes in the discount rate for bank borrowings, expanded access to funds for non-banks and changes in reserve requirements against bank deposits. The Federal Reserve has, most recently as a response to the COVID-19 pandemic, steeply increased the size of its balance sheet by buying securities and since the financial crises has paid interest on excess reserves held by banks at the Federal Reserve. The Federal Reserve also has decreased its target federal funds rate to near zero in response to the COVID -19 pandemic. Both the traditional and more recent methods are used in varying combinations to influence overall growth and distribution of bank loans, investments and deposits, interest rates on loans and securities, and rates paid for deposits. The monetary policies of the Federal Reserve have had a significant effect on the operating results of commercial banks and are expected to continue to do so in the future. The monetary policies of the Federal Reserve are influenced by various factors, including inflation, unemployment, and short-term and long-term changes in the international trade balance and in the fiscal policies of the U.S. Government. Given inflationary pressures during 2021, which have been seen to be more than a transitory reaction to supply concerns as a result of the pandemic, it is expected that the Federal Reserve will taper its buying of securities, reduce its balance sheet and raise its benchmark rate. Since the period during which the Federal Reserve increased the size of its balance sheet substantially above historical levels through the purchase of debt securities, the Federal Reserve has started to vary the size of its balance sheet, which might also affect interest rates. Future monetary policies, including whether and when the Federal Reserve will increase or decrease the federal funds rate and whether or at what pace it will reduce or increase the size of its balance sheet, and the effect of such policies on the future business and earnings of the Company and our subsidiary bank cannot be predicted.

Supervision and Regulation

We are extensively regulated under federal and state law. The following is a brief summary of certain aspects of that regulation that are material to us and does not purport to be a complete description of all regulations that affect us or all aspects of those regulations. To the extent particular statutory and regulatory provisions are described, the description is qualified in its entirety by reference to the particular statute or regulation. Proposals to change the laws and regulations governing the banking industry are frequently raised at both the state and federal levels. The likelihood and timing of any changes in these laws and regulations, and the impact such changes may have on the Company and the Bank, are difficult to ascertain. In addition to laws and regulations, bank regulatory agencies may issue policy

9

Table of Contents

statements, interpretive letters and similar written guidance applicable to the Company or the Bank. A change in applicable laws, regulations or regulatory guidance, or in the manner such laws, regulations or regulatory guidance are interpreted by regulatory agencies or courts, may have a material adverse effect on the Company’s and the Bank’s business, operations, and earnings. Supervision, regulation, and examination of banks by regulatory agencies are intended primarily for the protection of depositors and customers, the deposit insurance fund and the U.S. banking and financial system rather than shareholders.

Both the scope of the laws and regulations and the intensity of the supervision to which we are subject have increased in recent years, initially in response to the financial crisis, and more recently in light of other factors such as technological and market changes. As described in further detail below, the Company and the Bank have become subject to additional regulatory requirements as a result of the growth of their assets. Regulatory enforcement and fines have also increased across the banking and financial services sector. Many of these changes have occurred as a result of the Dodd-Frank Act Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) and its implementing regulations. While there have been some changes in the post financial crisis framework applicable to the Company, the Company expects that its business will remain subject to extensive regulation and supervision. The scope of regulation and the intensity of supervision will likely become higher under the current presidential administration, including increased scrutiny, supervisory discouragement or even possible denials of bank mergers and acquisitions by federal bank regulators.

We are also subject to the disclosure and regulatory requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, both as administered by the SEC, as well as the rules of Nasdaq that apply to companies with securities listed on the Nasdaq Global Select Market.

Regulation of the Company

We are registered as a bank holding company with the Federal Reserve under the Bank Holding Company Act of 1956 (the “BHC Act”) and have elected to be a financial holding company. As a financial holding company, we are subject to comprehensive regulation, examination and supervision by the Federal Reserve and are subject to its regulatory reporting requirements. Federal law subjects financial holding companies, such as the Company, to particular restrictions on the types of activities in which they may engage, and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations.

As a financial holding company, we are permitted to engage in, and be affiliated with companies engaging in, a broader range of activities than those permitted for a bank holding company. Bank holding companies are generally restricted to engaging in the business of banking, managing or controlling banks and certain other activities determined by the Federal Reserve to be related closely to banking. Financial holding companies may also engage in activities that are considered to be financial in nature, as well as those incidental or complementary to financial activities, including certain insurance underwriting activities. We and the Bank must each remain “well-capitalized” and “well-managed” and the Bank must receive a Community Reinvestment Act (“CRA”) rating of at least “Satisfactory” at its most recent examination in order for us to maintain our status as a financial holding company. In addition, the Federal Reserve has the power to order a financial holding company or its subsidiaries to terminate any activity or terminate its ownership or control of any subsidiary, when it has reasonable cause to believe that continuation of such activity or such ownership or control constitutes a serious risk to the financial safety, soundness, or stability of any bank subsidiary of that financial holding company.

A financial holding company is required to act as a source of financial and managerial strength to its subsidiary bank and to maintain resources adequate to support its bank. The term “source of financial strength” has been defined as the ability of a company to provide financial assistance to its insured depository institution subsidiaries in the event of financial distress. The appropriate federal banking agency for the depository institution (in this case the Office of the Comptroller of the Currency or “OCC”) may require reports from the Company to assess its ability to serve as a source of strength and to enforce compliance with the source-of-strength requirements by requiring the holding company to provide financial assistance to the Bank if its capital were to become impaired. If the Company fails to provide such assistance within three months, it could be ordered to sell its stock of the Bank to cover the deficiency. Any capital loans by the Company to the Bank would be subordinate in right of payment to deposits and certain other debts of the Bank. In the event of the Company’s bankruptcy, any commitment by the Company to a federal bank regulatory agency to maintain the capital of the Bank would be assumed by the bankruptcy trustee and entitled to a priority of payment.

The BHC Act requires that a financial holding company obtain the prior approval of the Federal Reserve before (i) acquiring direct or indirect ownership or control of more than 5% of the voting shares of any additional bank or bank holding company, (ii) taking any action that causes an additional bank or bank holding company to become a subsidiary of the financial holding company, or (iii) merging or consolidating with any other bank holding company. The Federal Reserve may not approve any such transaction that would result in a monopoly or would be in furtherance of any combination or conspiracy to monopolize or attempt to monopolize the business of banking in any section of the United States, or the effect of which may be substantially to lessen competition or to tend to create a monopoly in any section of the country, or that in any other manner would be in restraint of trade, unless the anticompetitive effects of the proposed transaction are clearly outweighed by the public interest in meeting the convenience and needs of the community to be served. The Federal Reserve is also required to consider (1) the financial and managerial resources of the companies involved, including pro forma capital ratios; (2) the risk to the stability of the United States banking or financial system; (3) the convenience and needs of the communities to be served, including the companies’ performance under the CRA; and (4) the effectiveness of the companies in combatting money laundering. We are permitted under applicable federal and state law to make out of state acquisitions and mergers of other banks and bank holding companies, subject to the requirements summarized above.

Federal law restricts the amount of voting stock of a bank holding company and a bank that a person may acquire without the prior approval of banking regulators. The overall effect of such laws is to make it more difficult to acquire a bank holding company and a bank by tender offer or similar means than it might be to acquire control of another type of corporation. Consequently, shareholders of the Company may be less likely to benefit from the rapid increases in stock prices that may result from tender offers or similar efforts to acquire control of other companies. Federal law also imposes restrictions on acquisitions of stock in a bank holding company or a national bank. Under the federal Change in Bank Control Act and the regulations thereunder, a person or group must give advance notice to the Federal Reserve before acquiring control of any bank holding company, such as the Company, and the OCC before acquiring control of any national bank, such as the Bank. Upon receipt of such notice, the bank regulatory agencies may approve or disapprove the acquisition. The Change in Bank Control Act creates a rebuttable presumption of control if a member or group acquires a certain percentage or more of a bank holding company’s or bank’s voting stock, or if one or more other control factors set forth in the Act are present. As a result, a person or entity generally must provide prior notice to the Federal Reserve before acquiring the power to vote 10% or more of our outstanding common stock. Investors should be aware of these requirements when acquiring shares of our stock.

Regulation of the Bank

The Bank is a national bank subject to comprehensive regulation, examination and supervision by the OCC and is subject to its regulatory reporting requirements. The deposits of the Bank are insured by the FDIC and, accordingly, the Bank is also subject to certain FDIC regulations and the FDIC has backup examination authority and some enforcement powers over the Bank. The Bank also is subject to certain Federal Reserve regulations. These regulations include limitations on loans to a single borrower and to its directors, officers and employees; restrictions on the opening and closing of branch offices; the maintenance of required capital and liquidity ratios; the granting of credit under equal and fair conditions; the disclosure of the costs and terms of such credit, requirements to maintain reserves against deposits and loans, limitation on the types of investment that may be made and requirements governing risk management practices.

The Bank also is subject to restrictions on its ability to lend to and engage in other transactions with the Company and the Bank’s other affiliates. Under these provisions, individual loans or other extensions of credit between the Bank and the Company or any nonbank affiliate generally are limited to 10% of the Bank’s capital and surplus, and all such transactions between the Bank and either the Company or any nonbank affiliate are limited to 20% of the Bank’s capital and surplus. Loans and other extensions of credit from the Bank to any affiliate generally are required to be secured by eligible collateral in specified amounts. In addition, any transaction between the Bank and any affiliate are required to be on arm’s length terms and conditions. The definition of “extension of credit” for these purposes includes credit exposures arising from a derivative transaction, a repurchase or reverse repurchase agreement and a securities lending or borrowing transaction. Federal banking laws also place similar restrictions on loans and other extensions of credit by FDIC-insured banks, such as the Bank, to their directors, executive officers and principal shareholders. These restrictions have not had a material impact on the Company or the Bank.

Federal Reserve rules require depository institutions, such as the Bank, to maintain reserves against their transaction accounts, primarily NOW and regular checking accounts. Effective March 26, 2020, the reserve was

11

suspended with no reserve requirements. These reserve requirements are subject to annual adjustment by the Federal Reserve.

The Bank is permitted under federal law to branch on a de novo basis across state lines where the laws of the state would permit banks chartered by that state to open a de novo branch.

Supervision, Examination and Enforcement

The Federal Reserve, OCC and FDIC have broad supervisory, examination and enforcement authority with regard to bank holding companies and banks, including the power to impose nonpublic supervisory agreements, issue cease and desist or removal orders, impose fines and other civil and criminal penalties, initiate injunctive actions, terminate deposit insurance and appoint a conservator or receiver. In general, these actions may be initiated for violations of laws and regulations, as well as engagement in unsafe and unsound practices, and certain of these actions also may be taken against an “institution affiliated party” as defined in the law. Specifically, the regulators may direct a bank holding company or bank to, among other things, increase its capital, sell subsidiaries or other assets, limit its dividends and distributions, restrict its growth or remove officers and directors. Supervision and examinations are confidential, and the outcomes of these actions may not be made public.

We also are supervised and examined by the Consumer Financial Protection Bureau (“CFPB”) with respect to consumer protection laws and regulations.

FDIC Insurance Assessments and Depositor Preference

The deposits of the Bank are insured by the FDIC up to the limits under applicable law, which currently are set at $250,000 for accounts under the same name and title. The Bank is subject to deposit insurance premium assessments. The FDIC imposes a risk-based deposit premium assessment system. Under this system, the assessment rates for an insured depository institution vary according to the level of risk incurred in its activities. To arrive at an assessment rate for a banking institution, the FDIC places it in one of four risk categories determined by reference to its capital levels and supervisory ratings. In the case of those institutions in the lowest risk category, the FDIC further determines its assessment rate based on certain specified financial ratios or, if applicable, long-term debt ratings. The assessment rate schedule can change from time to time, at the discretion of the FDIC, subject to certain limits. Under the current system, premiums are assessed quarterly. The FDIC has published guidelines on the adjustment of assessment rates for certain institutions. In addition, insured depository institutions have been required to pay a pro rata portion of the interest due on the obligations issued by the Financing Corporation to fund the closing and disposal of failed thrift institutions by the Resolution Trust Corporation.

The FDIC uses a performance score and loss-severity score to calculate the Bank’s initial FDIC assessment rate. In calculating these scores, the FDIC uses the Bank’s capital level and regulatory supervisory ratings and certain financial measures to assess the Bank’s ability to withstand asset-related and funding related stress, and make certain adjustments based on risk factors that are not adequately captured in these calculations.

Insurance of deposits may be terminated by the FDIC upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by a bank’s federal regulatory agency. Deposits and certain claims for administrative expenses and employee compensation against insured depository institutions are afforded a priority over other general unsecured claims against the institution, including federal funds and letters of credit, in the liquidation or other resolution of that institution by any receiver appointed by federal authorities. These priority creditors include the FDIC.

Dividend Restrictions

The Company is a legal entity separate and distinct from its banking and other subsidiaries and has in the past relied on dividends from the Bank as its primary source of liquidity. There are limitations on the payment of dividends by the Bank to the Company, as well as by the Company to its shareholders.

The OCC has the general authority to limit the dividends paid by the Bank if such payment may be deemed to constitute an unsafe and unsound practice. The Bank may not pay dividends from its paid-in surplus. All dividends

12

Table of Contents

must be paid out of undivided profits then on hand, after deducting expenses, including reserves for losses and bad debts. In addition, a national bank, such as the Bank, is prohibited from declaring a dividend on its shares of common stock until its surplus equals its stated capital, unless there has been transferred to surplus no less than one/tenth of the bank’s net profits of the preceding two consecutive half-year periods (in the case of an annual dividend). The approval of the OCC is required if the total of all dividends declared by a national bank in any calendar year exceeds the total of its net profits for that year combined with its retained net profits for the preceding two years, less any required transfers to surplus.

We and the Bank must maintain the applicable common equity Tier 1 ("CET1") capital conservation buffer of 2.5% to avoid becoming subject to restrictions on capital distributions, including dividends. For more information on the CET1 capital conservation buffer, see Part I Item 1. Supervision and Regulation – Capital Requirements.

In addition, Federal Reserve policy provides that bank holding companies, such as the Company, should generally pay dividends to shareholders only if (i) the organization’s net income available to common shareholders over the past year has been sufficient to fully fund the dividends; (ii) the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition; and (iii) the organization will continue to meet minimum capital adequacy ratios. The policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to the bank holding company’s capital structure. Bank holding companies also are required to consult with the Federal Reserve before increasing dividends or redeeming or repurchasing capital instruments. Additionally, the Federal Reserve could prohibit or limit the payment of dividends by a bank holding company if it determines that payment of the dividend would constitute an unsafe or unsound practice.

Capital Requirements

We are required under federal law to maintain certain minimum capital levels at each of the Company and the Bank. The federal banking agencies have issued substantially similar risk-based and leverage capital requirements to banking organizations they supervise. Under these requirements, the Company and the Bank are required to maintain certain capital standards based on ratios of capital to total assets and capital to risk-weighted assets. The requirements also define the weights assigned to assets and off-balance sheet items to determine the risk-weighted asset components of the risk-based capital rules. The required capital ratios are minimums, and the Federal Reserve and OCC may determine that a banking organization, based on its size, complexity or risk profile, must maintain a higher level of capital in order to operate in a safe and sound manner. Risks such as concentration of credit risks and the risk arising from non-traditional activities, as well as the institution’s exposure to a decline in the economic value of its capital due to changes in interest rates, and an institution’s ability to manage those risks are important factors that are to be taken into account by the federal banking agencies in assessing an institution’s overall capital adequacy.

Under the applicable capital rules, the Company and the Bank are subject to the following risk-based capital ratios: a CET1 risk-based capital ratio, a Tier 1 risk-based capital ratio, which includes CET1 and additional Tier 1 capital, and a total capital ratio, which includes Tier 1 and Tier 2 capital. CET1 is primarily comprised of the sum of common stock instruments and related surplus net of treasury stock, retained earnings, and certain qualifying minority interests, less certain adjustments and deductions, including with respect to goodwill, intangible assets, mortgage servicing assets and deferred tax assets subject to temporary timing differences. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, tier 1 minority interests and grandfathered trust preferred securities, if applicable. Upon the completion of the CenterState Merger in June 2020, the Company’s trust preferred securities no longer qualify as Tier 1 capital.

Tier 2 capital consists of instruments disqualified from Tier 1 capital, including qualifying subordinated debt, certain trust preferred securities, other preferred stock and certain hybrid capital instruments, and a limited amount of loan loss reserves up to a maximum of 1.25% of risk-weighted assets, subject to certain eligibility criteria. For institutions, such as us, that have exercised an opt-out election regarding the treatment of accumulated other comprehensive income (“AOCI”), up to 45% of net unrealized gains on available for sale equity securities with readily determinable fair market values are also included in Tier 2 capital. The capital rules also define the risk-weights assigned to assets and off-balance sheet items to determine the risk-weighted asset components of the risk-based capital rules, including, for example, “high volatility” commercial real estate, past due assets, structured securities and equity holdings.

Table of Contents

The capital rules require a minimum CET1 risk-based capital ratio of 4.5%, a minimum overall Tier 1 risk-based capital ratio of 6.0%, and a total risk-based capital ratio of 8.0%. In addition, the capital rules require a capital conservation buffer of 2.5% above each of the minimum capital ratio requirements (CET1, Tier 1, and total risk-based capital), which must be met for a bank or bank holding company to be able to pay dividends, engage in share buybacks or make discretionary bonus payments to executive management without automatic restriction. The capital conservation buffer is 2.50%, so a banking organization needs to maintain a CET1 capital ratio of at least 7%, a total Tier 1 capital ratio of at least 8.5% and a total risk-based capital ratio of at least 10.5% or it would be subject to restrictions on capital distributions and discretionary bonus payments to its executive management.

The leverage capital ratio, which serves as a minimum capital standard, is the ratio of Tier 1 capital to quarterly average total assets, less goodwill and other disallowed intangible assets. The required minimum leverage ratio for all banks and bank holding companies is 4%.

To be well-capitalized, the Bank must maintain the following capital ratios:

| • | CET1 risk-based capital ratio of 6.5% or greater;

| • | Tier 1 risk-based capital ratio of 8.0% or greater;

| • | Total risk-based capital ratio of 10.0% or greater; and

| • | Tier 1 leverage ratio of 5.0% or greater.

The Federal Reserve has not yet revised the well-capitalized standard for bank holding companies to reflect the higher capital requirements imposed under the current capital rules. For purposes of the Federal Reserve’s Regulation Y, including determining whether a bank holding company meets the requirements to be a financial holding company, bank holding companies, such as the Company, must maintain a Tier 1 risk-based capital ratio of 6.0% or greater and a total risk-based capital ratio of 10.0% or greater to be well-capitalized. If the Federal Reserve were to apply the same or a very similar well-capitalized standard to bank holding companies as that applicable to the Bank, the Company’s capital ratios as of December 31, 2021 would exceed such revised well-capitalized standard. The Federal Reserve may require bank holding companies, including the Company, to maintain capital ratios substantially in excess of mandated minimum levels, depending upon general economic conditions and a bank holding company’s particular condition, risk profile and growth plans.

Failure to be well-capitalized or to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on our operations or financial condition. For example, only a well-capitalized depository institution may accept brokered deposits without prior regulatory approval. Failure to be well-capitalized or to meet minimum capital requirements could also result in restrictions on the Company’s or the Bank’s ability to pay dividends or otherwise distribute capital or to receive regulatory approval of applications or other restrictions on its growth.

As of December 31, 2021, the Company’s and the Bank’s regulatory capital ratios were above the well-capitalized standards and met the fully phased-in capital conservation buffer. Please refer to the table below for a summary of the Company’s and the Bank’s regulatory capital ratios as of December 31, 2021 and 2020, calculated using the regulatory capital methodology applicable to us during 2021.

The Company has elected to delay for two years the estimated impact of CECL on regulatory capital, followed by a three-year transition period to phase out the aggregate amount of benefit during the initial two-year delay for a total five-year transition. The estimated impact of CECL on regulatory capital (modified CECL transitional amount) is calculated as the sum of the impact on retained earnings upon adoption of CECL (CECL transitional amount) and the calculated change in the ACL relative to the ACL upon adoption of CECL multiplied by a scaling factor of 25%. The scaling factor is used to approximate the difference in the ACL under CECL relative to the incurred loss methodology. The modified CECL transitional amount will be calculated each quarter for the first two years of the five-year transition. The amount of the modified CECL transition amount will be fixed as of December 31, 2021, and that amount will be subject to the three-year phase out.

Safety and Soundness Guidelines

The federal banking agencies have adopted guidelines prescribing safety and soundness standards relating to internal controls, risk management, information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth and compensation, fees and benefits. These guidelines in general require appropriate systems and practices to identify and manage specified risks and exposures. The guidelines prohibit excessive compensation as an unsafe and unsound practice and characterize compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer or employee, director or principal shareholder. In addition, the agencies have adopted regulations that authorize but do not require an agency to order an institution that has been given notice by the agency that it is not in compliance with any of the safety and soundness standards to submit a compliance plan. If after being so notified, an institution fails to submit an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order directing other actions of the types, including those that may limit growth or capital distributions.

Lending Standards and Guidance

The federal banking agencies have adopted uniform regulations prescribing standards for extensions of credit that are secured by liens or interests in real estate or made for the purpose of financing permanent improvements to real estate. Under these regulations, all insured depository institutions, such as the Bank, must adopt and maintain written policies establishing appropriate limits and standards for extensions of credit that are secured by liens or interests in real estate or are made for the purpose of financing permanent improvements to real estate. These policies must establish loan portfolio diversification standards, prudent underwriting standards (including loan-to-value limits) that are clear and measurable, loan administration procedures, and documentation, approval and reporting requirements. The real estate lending policies must reflect consideration of the federal bank regulators’ Interagency Guidelines for Real Estate Lending Policies.

The federal banking agencies have also jointly issued guidance on “Concentrations in Commercial Real Estate Lending” (the “Guidance”), which defines commercial real estate loans as exposures secured by raw land, land development and construction (including 1-4 family residential construction), multi-family property, and non-farm nonresidential property where the primary or a significant source of repayment is derived from rental income associated with the property (that is, loans for which 50% or more of the source of repayment comes from third-party, non-affiliated, rental income) or the proceeds of the sale, refinancing, or permanent financing of the property. The Guidance requires that appropriate processes be in place to identify, monitor and control risks associated with real estate lending concentrations. If a concentration is present, management must employ heightened risk management practices that address key elements, including board and management oversight and strategic planning, portfolio management, development of underwriting standards, risk assessment and monitoring through market analysis and stress testing, and maintenance of increased capital levels as needed to support the level of commercial real estate lending. The required heightened risk management practices could include enhanced strategic planning, underwriting policies, risk management, internal controls, portfolio stress testing and risk exposure limits as well as appropriately designed compensation and incentive programs. Higher allowances for loan losses and capital levels may also be required. The Guidance states that the following metrics may indicate a concentration of commercial real estate loans, but that these metrics are neither limits nor a safe harbor: (1) total reported loans for construction, land development, and other land represent 100% or more of total risk-based capital; or (2) total reported loans secured by multi-family properties, non-farm non-residential properties (excluding those that are owner-occupied), and loans for construction, land development, and other land represent 300% or more of total risk-based capital and the bank’s commercial real estate loan portfolio

has increased 50% or more during the pr ior 36 months. As of December 31, 2021, our total reported loans for construction, land development, and other land were 55% of the Bank’s total risk based capital and our total reported loans secured by multifamily and non-farm nonresidential properties and loans for construction, land development, and other land were 239% of the Bank’s total risk based capital.

Consumer Protection Laws

The Bank is subject to a number of federal laws designed to protect its customers. These consumer protection laws apply to a broad range of our activities and to various aspects of our business and include laws relating to interest rates, fair lending, disclosures of credit terms and estimated transaction costs to consumer borrowers, debt collection practices, the use of and the provision of information to consumer reporting agencies, and the prohibition of unfair, deceptive or abusive acts or practices in connection with the offer, sale or provision of consumer financial products and services. Administration of many of these consumer protection rules are the responsibility of the CFPB, which has exclusive supervisory authority over insured depository institutions with more than $10 billion in total assets and any affiliates thereof. The CFPB also has authority to define and prevent unfair, deceptive and abusive practices in the consumer financial area, and expanded data collecting powers for purposes of determining bank compliance with the fair lending laws.

The CFPB has promulgated many mortgage-related final rules, including rules related to the ability to repay and qualified mortgage standards, mortgage servicing standards, loan originator compensation standards, high-cost mortgage requirements, Home Mortgage Disclosure Act requirements and appraisal and escrow standards for higher priced mortgages. In addition, several proposed revisions to mortgage-related rules are pending finalization. The mortgage-related final rules issued by the CFPB have materially restructured the origination, servicing and securitization of residential mortgages in the United States. These rules have impacted, and will continue to impact, the business practices of mortgage lenders, including the Company. For example, under the CFPB’s Ability to Repay and Qualified Mortgage rule, before making a mortgage loan, a lender must establish that a borrower has the ability to repay the mortgage. “Qualified mortgages”, as defined in the rule, are presumed to comply with this requirement and, as a result, present less litigation risk to lenders. For a loan to qualify as a qualified mortgage, the loan must satisfy certain limits on terms and conditions, pricing and a maximum debt-to-income ratio. Loans eligible for purchase, guarantee or insurance by a government agency or government-sponsored enterprise are exempt from some of these requirements. Satisfying the qualified mortgage standards, ensuring correct calculations are made for individual loans, recordkeeping and monitoring, as well as understanding the effect of the qualified mortgage standards on CRA obligations, impose significant new compliance obligations on, and involve compliance costs for, mortgage lenders, including the Company.

Under applicable law, the Bank, as a debit card issuer, may receive a maximum permissible interchange fee equal to no more than $0.21 plus 5 basis points of the transaction value for many types of debit interchange transactions. Further, a debit card issuer may also recover $0.01 per transaction for fraud prevention purposes if the issuer complies with certain fraud-related requirements required by the Federal Reserve. In addition, the Federal Reserve rules governing routing and exclusivity require debit card issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product.

Community Reinvestment Act

The CRA requires the appropriate federal banking agency, in connection with its examination of a bank, to assess the bank’s record in meeting the credit needs of the communities served by the institution, including low and moderate income neighborhoods. Furthermore, the relevant federal bank regulatory agency is required to consider a bank’s CRA assessment when considering the bank’s application to, among other things, merge or consolidate with or acquire the assets or assume the liabilities of an insured depository institution or open or relocate a branch office. The relevant federal banking agency, the OCC in the Bank’s case, examines each bank and assigns it a public CRA rating. Under the CRA, institutions are assigned a rating of “outstanding,” “satisfactory,” “needs to improve,” or “unsatisfactory.” The Bank received a "satisfactory” rating at its most recent CRA evaluation.

During 2020, the OCC engaged in a rulemaking to amend the CRA, which the FDIC and the Federal Reserve declined to join. On December 4, 2021, the OCC rescinded the 2020 final rulemaking, and reinstated the previous existing interagency CRA rule. The OCC has also issued a joint statement with the FDIC and Federal Reserve stating that they are committed to working jointly to modernize the CRA rules.

Anti-Money Laundering Rules

The Bank Secrecy Act, the USA PATRIOT Act of 2001, and other laws and regulations require financial institutions, among other duties, to institute and maintain an effective anti-money laundering (“AML”) program and file suspicious activity and currency transaction reports when appropriate. Among other things, these laws and regulations require the Bank to take steps to prevent the use of the Bank to facilitate the flow of illegal or illicit money, to report large currency transactions and to file suspicious activity reports. The Bank also is required to develop and implement a comprehensive AML compliance program. Banks must also have in place appropriate “know your customer” policies and procedures.

The Anti-Money Laundering Act of 2020, enacted on January 1, 2021 as part of the National Defense Authorization Act, does not directly impose new requirements on banks, but requires the U.S. Treasury Department to issue National Anti-Money Laundering and Countering the Financing of Terrorism Priorities, and conduct studies and issue regulations that may, over the next few years, significantly alter some of the due diligence, recordkeeping and reporting requirements that the Bank Secrecy Act and USA PATRIOT Act impose on banks. The Anti-Money Laundering Act of 2020 also contains provisions that promote increased information-sharing and use of technology, and increases penalties for violations of the Bank Secrecy Act and includes whistleblower incentives, both of which could increase the prospect of regulatory enforcement.

Violations of these requirements can result in substantial civil and criminal sanctions, and the federal banking agencies are required to consider the effectiveness of a financial institution’s AML activities when reviewing bank mergers and bank holding company acquisitions. In addition to other bank regulatory agencies, the federal Financial Crimes Enforcement Network of the Department of the Treasury is authorized to impose significant civil money penalties for violations of those requirements and has recently engaged in coordinated enforcement efforts with the state and federal banking regulators, as well as the U.S. Department of Justice, CFPB, Drug Enforcement Administration, and Internal Revenue Service.

OFAC Regulation

The Office of Foreign Assets Control or OFAC is responsible for administering economic sanctions that affect transactions with designated foreign countries, nationals and others, as defined by various Executive Orders and in various legislation. OFAC-administered sanctions take many different forms. For example, sanctions may include: (1) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on U.S. persons engaging in financial transactions relating to, making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (2) a blocking of assets in which the government or “specially designated nationals” of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction, including property in the possession or control of U.S. persons. OFAC also publishes lists of persons, organizations and countries suspected of aiding, harboring or engaging in terrorist acts, known as Specially Designated Nationals and Blocked Persons. Blocked assets, for example property and bank deposits, cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. If we find a name on any transaction, account or wire transfer that is on an OFAC list, we must freeze or block such account or transaction, file a suspicious activity report and notify the appropriate authorities. Failure to comply with these sanctions could have serious legal and reputational consequences.

Privacy, Data Protection and Cyber Security

Various federal and state laws and regulations contain extensive data privacy and cybersecurity provisions, and the regulatory framework for data privacy and cybersecurity is in considerable flux and rapidly evolving. Current federal law requires financial institutions to periodically disclose their privacy policies and practices relating to sharing such information and enables retail customers to opt out of our ability to share information with unaffiliated third parties under certain circumstances. Other federal and state laws and regulations impact our ability to share certain information with affiliates and non-affiliates for marketing and/or non-marketing purposes, or to contact customers with marketing offers. Current federal law also requires financial institutions to implement a comprehensive information security program that includes administrative, technical and physical safeguards to ensure the security and confidentiality of customer records and information. These security and privacy policies and procedures for the protection of personal and confidential information are in effect across all businesses and geographic locations. Federal law also makes it a criminal offense, except in limited circumstances, to obtain or attempt to obtain customer information of a financial

nature by fraudulent or deceptive means.

In November 2021, the Federal Reserve, OCC, and FDIC adopted a new regulation that, among other things, requires a banking organization to notify its primary federal regulators within 36 hours after identifying a "computer-security incident" that the banking organization believes in good faith could materially disrupt or degrade its business or operations in a manner that would, among other things, jeopardize the viability of its operations, result in customers being unable to access their deposit and other accounts, result in a material loss of revenue, profit or franchise value, or pose a threat to the financial stability of the U.S.

Data privacy and data protection are also areas of increasing state legislative focus. For example, the California Consumer Privacy Act of 2018 (“CCPA”) gives consumers the right to request disclosure of information collected about them, and whether that information has been sold or shared with others, the right to request deletion of personal information (subject to certain exceptions), the right to opt out of the sale of the consumer’s personal information, and the right not to be discriminated against for exercising these rights. The CCPA contains several exemptions, including that many, but not all, requirements of the CCPA are inapplicable to information that is collected, processed, sold, or disclosed pursuant to federal law. Because our correspondent division has an office in California, we have complied with the CCPA. Similar laws have been or may be adopted by other states where we do business, such as the Consumer Data Protection Act, a privacy law adopted in Virginia in 2021 that grants consumers rights over their personal data. The federal government may also pass data privacy or data protection legislation.

Like other lenders, the Bank uses credit bureau data in their underwriting activities. Use of such data is regulated under the Fair Credit Reporting Act, which also regulates reporting information to credit bureaus, prescreening individuals for credit offers, sharing of information between affiliates, and using affiliate data for marketing purposes. Similar state laws may impose additional requirements on us and our subsidiaries. The Bank is also subject to rules and regulations issued by the Federal Trade Commission, which regulates unfair or deceptive acts or practices, including with respect to data privacy and cybersecurity.

Future Legislation and Regulation

Banking statutes, regulations and policies are continually under review by Congress, state legislatures and federal and state regulatory agencies. In addition to laws and regulations, state and federal bank regulatory agencies may issue policy statements, interpretive letters and similar written guidance applicable to us and our subsidiaries. We cannot predict the substance or impact of pending or future legislation or regulation or the application of those laws or regulations, although enactment of any significant proposal could affect how we operate and could significantly increase our costs, impede the efficiency of internal business processes or limit our ability to pursue business opportunities in an efficient manner, any of which could materially and adversely affect our business, financial condition and results of operations.

Risk Factors

An investment in our common stock is subject to risks inherent in our business. The following discussion highlights the risks that management believes are material for our Company, but do not necessarily include all the risks that we may face. You should carefully consider the risk factors and uncertainties described below and elsewhere in this Annual Report on Form 10-K ("Report") in evaluating an investment in our common stock.

Risks relating to our Business and Business Strategy

We face risks and uncertainties related to our proposed Merger with ACBI.

​

The Company and ACBI operate and, until the completion of the Merger, will continue to operate independently. There can be no assurances that the businesses of the Company and ACBI can be integrated successfully. It is possible that the integration process could result in the loss of key Company or ACBI employees, the loss of customers, the disruption of either company’s ongoing businesses, inconsistencies in standards, controls, procedures and policies, unexpected integration issues, higher than expected integration costs and an overall post-completion integration process that takes longer than originally anticipated. The success of the Merger will depend on, among other things, the ability of the Company and ACBI to combine their businesses in a manner that facilitates growth opportunities and realizes cost savings. However, if the combined company is not able to successfully achieve these objectives, the anticipated benefits of the Merger may not be realized fully, or at all, or may take longer to realize than expected.

Failure to complete our proposed Merger with ACBI could negatively impact our business, financial results and stock price.

​

If our proposed merger with ACBI is not completed for any reason, our ongoing business may be adversely affected, and, without realizing any of the benefits of having completed the Merger, we will be subject to a number of risks, including the following:

| • | We will be required to pay certain costs relating to the merger, whether or not the Merger is completed, such as legal, accounting, financial advisor and printing fees;

| • | The ACBI Merger Agreement places certain restrictions on the conduct of both the Company’s and ACBI’s business before completion of the Merger, which may adversely affect our ability to execute certain of our business strategies; and

21

Table of Contents

| • | Matters relating to the Merger are requiring substantial commitments of time and resources by our management, which could have been devoted to other opportunities that may have been beneficial to us, as an independent company.

In addition, if the Merger is not completed, we may experience negative reactions from the financial markets and from our customers and employees. For example, we may be impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the Merger, without realizing any of the anticipated benefits of completing the Merger. The market price of our common stock could decline to the extent that the current market prices reflect a market assumption that the Merger will be completed. We also could be subject to litigation related to any failure to complete the Merger or to proceedings commenced against us to perform our obligations under the ACBI Merger Agreement. If the Merger is not completed, we cannot assure you that the risks described above will not materialize and will not materially affect our business, financial results and stock price.

​

The Company may not be able to integrate successfully the companies or to realize the anticipated benefits of the Merger.

​

Assuming the Merger is approved, the successful integration of systems and operations will depend substantially on the Company’s ability to consolidate successfully corporate cultures, management teams, operations, systems, processes and procedures and to eliminate redundancies and costs. While we have substantial experience in successfully integrating institutions we have acquired, we may encounter difficulties during integration, such as:

| • | the loss of key employees and clients;

| • | the disruption of operations and businesses;

| • | inability to maintain and increase competitive presence in the Atlanta market;

| • | loan, deposit, and revenue attrition;

| • | inconsistencies in standards, control procedures and policies;

| • | unexpected issues with costs, operations, personnel, technology; and

| • | problems with the assimilation of new operations, sites or personnel.

​

Integration activities could divert resources from regular operations. In addition, general market and economic conditions or governmental actions affecting the financial industry generally may inhibit the Company’s successful integration of these entities.

​

The Company and ACBI entered into the ACBI Merger Agreement with the expectation that the Merger would result in various synergies including, among other things, benefits relating to enhanced revenues, a strengthened and expanded market position for the combined organization in the Atlanta market, technology efficiencies, cost savings and operating efficiencies. Achieving the anticipated benefits of the Merger is subject to a number of uncertainties, including whether the Company integrates the institutions in an efficient and effective manner, as well as general competitive factors in the marketplace. Failure to achieve or delays in achieving these anticipated benefits could result in a share price reduction as well as increased costs, decreases in the amount of expected revenues, and diversion of management’s time and energy and could materially and adversely affect the Company’s financial condition, results of operations, business and prospects.

The Company will continue to incur substantial expenses related to the ACBI Merger and the integration.

​

The Company must integrate ACBI’s processes, policies, procedures, operations, technologies and systems. In addition, the Merger may increase the Company’s compliance and legal risks, including increased litigation or regulatory actions such as fines or restrictions related to the business practices or operations of the combined business. While the Company has assumed that a certain level of expenses would be incurred, many factors beyond the Company’s control could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that the Company will incur are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the expected savings from the elimination of duplicative expenses and the realization of economies of scale. The amount and timing of future charges to earnings as a result of merger or integration expenses are uncertain.

​

The Company will continue to incur substantial expenses related to the conversion and integration of the CenterState Merger.

​

While the Company completed the conversion of systems in connection with the CenterState Merger in May 2021, we continue to address clean up integration tasks which could delay the realization of merger synergies and increase the Company’s compliance and operational costs. While the Company has assumed that a certain level of expenses would be incurred, many factors beyond the Company’s control could affect the total amount or the timing of any remaining integration expenses. Moreover, many of the expenses that the Company will incur are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the expected savings from the elimination of duplicative expenses and the realization of economies of scale. The amount and timing of future charges to earnings as a result of merger or integration expenses are uncertain.

​

The COVID-19 pandemic has adversely affected our business, financial condition and results of operations, and the ultimate impacts of the pandemic on our business, financial condition and results of operations will depend on future developments and other factors that are highly uncertain and will be impacted by the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.

​

Although the global economy has begun to recover from the COVID-19 pandemic as many health and safety restrictions have been lifted and vaccine distribution has increased, certain adverse consequences of the pandemic continue to impact the macroeconomic environment and may persist for some time, including labor shortages and disruptions of global supply chains. These consequences of the pandemic have resulted in significant adverse effects for many different types of businesses nationwide and in the regions in which we operate, including, among others, those in the travel, hospitality and food and beverage industries.

​

The global supply chain has been drastically disrupted during the pandemic and remains challenged as it adapts and responds. In part as a result, inflation has exceeded the Federal Reserve’s two percent (2%) annual target, and there is a risk that inflation may become higher or persist for longer periods of time and not decrease even as supply chain issues are resolved. Additional impacts of the COVID-19 pandemic on our business could be widespread and material, and may include, or exacerbate, among other consequences, the following:

| • | employees contracting COVID-19;

| • | reductions in our operating effectiveness as our employees work from home;

| • | work stoppages, forced quarantines, or other interruptions of our business;

| • | employee fatigue as a result of the length of the pandemic response;

| • | unavailability of key personnel necessary to conduct our business activities;

| • | effects on key employees, including operational management personnel and those charged with preparing, monitoring and evaluating our financial reporting and internal controls;

| • | increased cybersecurity risks as 41% of the workforce works from home;

| • | sustained closures of our branch lobbies or the offices of our customers;

| • | declines in demand for loans and other banking services and products;

| • | reduced consumer spending due to both job losses and other effects attributable to the COVID-19 pandemic;

| • | volatile performance of our investment securities portfolio;

| • | decline in the credit quality of our loan portfolio, owing to the effects of the COVID-19 pandemic in the markets we serve, leading to a need to increase our allowance for credit losses;

| • | declines in value of collateral for loans, including real estate collateral;

| • | declines in the net worth and liquidity of borrowers and loan guarantors, impairing their ability to honor commitments to us;

| • | a reduction in fee income from reduced demand for loans and deposit services,

| • | a reduction of net interest margin from reductions in interest rates and the yield curve;

23

Table of Contents

| • | an increase in expenses; and

| • | declines in demand resulting from businesses being deemed to be “non-essential” by governments in the markets we serve, and from “non-essential” and “essential” businesses suffering adverse effects from reduced levels of economic activity in our markets.

​

A resurgence of the pandemic or a decrease in the effectiveness of vaccines could worsen these impacts and also affect the Company’s capital and liquidity position, cause an outflow of deposits, cause significant property damage, in case of civil unrest or vandalism, influence the recognition of credit losses on loans and securities and increase the allowance for credit losses, result in additional lost revenue, cause additional increases in expenses, result in goodwill impairment charges, result in the impairment of other financial and nonfinancial assets, and increase the Company’s cost of capital. These factors, together or in combination with other events or occurrences that may not yet be known or anticipated, may materially and adversely affect our business, financial condition and results of operations.

​

The ongoing COVID-19 pandemic resulted in more volatile stock prices for many companies, including our own, as well as the trading prices for many other securities during 2021. The further spread of the COVID-19 outbreak, as well as ongoing or new governmental, regulatory and private sector responses to the pandemic, may not be successful or may result in increased pressure on the banking sector other economic activity generally and in the areas in which we operate. While loan demand has increased during the second half of 2021, any new or increased spread of the COVID-19 virus or increase in interest rates to address inflationary pressures could result in declines in demand for our banking products and services and could negatively impact, among other things, our liquidity, regulatory capital, goodwill and our growth strategy. In addition, while net interest margin has been, and is likely to continue to be, affected by the very low interest rate environment any increase in rates may increase the margin, allowing us to earn more on our assets. The Company participated in the SBA’s PPP as an eligible lender with the benefit of a government guaranty of loans to small business clients, many of whom may face difficulties even after being granted such a loan. The Company faces increased risks, in terms of credit, fraud risk and litigation, in light of its participation in these programs. Any one or more of these developments could have a material adverse effect on our business, financial condition and results of operations.

​

We are taking precautions to protect the safety and well-being of our employees and customers; however, the Company can make no assurance that the steps being taken will be adequate or deemed to be appropriate, nor can we predict the level of disruption which will occur to our employees’ ability to provide customer support and service. If we are unable to recover from a business disruption on a timely basis, our business, financial condition and results of operations could be materially and adversely affected. We may also incur additional costs to remedy damages caused by such disruptions, which could further adversely affect our business, financial condition and results of operations.

​

The implementation of new lines of business or new products and services may subject us to additional risk.

​

We continuously evaluate our service offerings and may implement new lines of business or offer new products and services within existing lines of business in new sales channels such as online and mobile banking in the future. There are substantial risks and uncertainties associated with these efforts. In developing and marketing new lines of business and/or new products and services, we undergo a new product process to assess the risks of and resources needed for the initiative, and invest significant time and resources to build internal controls, policies and procedures to mitigate those risks, including hiring experienced management to oversee the implementation of the initiative. Initial timetables for the introduction and development of new lines of business and/or new products or services and/or new sales channels may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives, and shifting market preferences, may also impact the successful implementation of a new line of business and/or a new product or service and/or sales channels. Furthermore, any new line of business and/or new product or service could require the establishment of new key and other controls and have a significant impact on our existing system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business and/or new products or services could have a material adverse effect on our business and, in turn, our financial condition and results of operations.

​

The adoption of the Current Expected Credit Loss (“CECL”) standard, the merger activity and the COVID-19 pandemic may result in increased volatility and further increases in our allowance for credit losses (“ACL”).

​

The measure of our ACL is dependent on the adoption and interpretation of applicable accounting standards, as well as external events, including the CenterState and ACBI mergers and the COVID-19 pandemic. We adopted the

24

Table of Contents

Financial Accounting Standards Board’s Current Expected Credit Loss, or CECL standard, in the first quarter of 2020. Under the CECL model, we are required to present certain financial assets carried at amortized cost, such as loans held for investment and held to maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount and certain Management judgments over the life of the loan. This initial measurement took place as of January 1, 2020 at the time of our adoption of CECL.

​

The CECL model may create more volatility in the level of our ACL, as compared to the “incurred loss” standard that we previously applied in determining our ACL. The CECL model requires us to estimate the lifetime “expected credit loss” with respect to loans and other applicable financial assets, which may change more rapidly than the level of “incurred losses” that would have been used to determine our allowance for loan losses under the prior incurred loss standard. While the Company has reduced the ACL over the past several quarters, the potentially material effects of the continuation of the COVID-19 pandemic on lifetime expected credit loss, and the challenges associated with estimating lifetime credit losses in view of the uncertain ultimate impacts of the pandemic, has resulted and may continue to result in increased volatility and significant additions to our ACL in the future, which could have a material and adverse effect on our business, financial condition and results of operations. The Company’s estimate of its ACL involves a high degree of judgment; therefore, the Company's process for determining expected credit losses may result in a range of expected credit losses. It is possible that others, given the same information, may at any point in time reach a different reasonable conclusion. Further, if management’s assumptions and judgments prove to be incorrect and the allowance for credit losses is inadequate to absorb losses going forward, or if bank regulatory authorities require us to increase the allowance for credit losses as a part of their examination process, our earnings and capital could be significantly and adversely affected.

​

Technological changes, including online and mobile banking, have the potential of disrupting our business model, and we may have fewer resources than many competitors to invest in technological improvements.

​

The financial services industry continues to undergo rapid technological changes with frequent introductions of new technology-driven products and services, including mobile and online banking services. Changes in customer behaviors have increased the need to offer these options to our customers. Further, the occurrence and continuation of the COVID-19 pandemic has accelerated technological change as our employees and the customers and communities to which we provide products and services experienced quarantines, cancellation of events and travel, business and school shutdowns, reduction in business activity and financial transactions, and supply chain interruptions.

​

In addition to serving clients better, investments in, and the effective use of, technology may increase efficiency and may enable financial institutions to reduce costs. These investments may not be sufficient or provide the anticipated benefits or desired return. We can make no assurance that investments will be sufficient to retain existing customers or attract new customers in the future.

​

Our future success will depend, in part, upon our ability to invest in and use technology to provide products and services that provide convenience to customers and to create additional efficiencies in operations. One of our strategic goals is to continue to focus on technological change and digital transformation of our product and service channels, which will impact how we deliver our products and services in the future as well as make our internal processes more efficient. We will need to make significant additional capital investments in technology in the future to achieve this strategic goal, and we may not be able to implement effectively new technology-driven products and services in a timely manner in response to changes in customer behaviors, thus adversely impacting our operations. Many competitors have substantially greater resources to invest in technological improvements than the Company.

​

Our business strategy includes continued growth, and our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively.

​

We intend to continue pursuing a growth strategy for our business. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered by companies in significant growth stages of development. Our ability to continue to grow successfully will depend on a variety of factors, including economic conditions in the markets in which we operate as well as in the U.S. and globally, continued availability of desirable business opportunities, the competitive responses from other financial and non-financial institution competitors in our market areas, our ability to continue to implement and improve our operational, credit, financial, management and other risks

Table of Contents

controls and processes and our reporting systems and procedures to manage a growing number of client relationships, and our ability to integrate our acquisitions and develop consistent policies throughout our various businesses. While we believe we have the management and other resources and internal systems in place to successfully manage our future growth, and we are expanding those resources and systems as we continue to grow, there can be no assurance growth opportunities will be available or growth will be successfully managed. In addition, if we are unable to manage future expansion in our operations, we may experience compliance and operational problems, have to slow the pace of growth, or have to incur additional expenditures beyond current projections to support such growth, any of which could adversely affect our business. Particularly in light of prevailing economic and competitive conditions, we cannot assure you we will be able to expand our market presence in our existing markets or successfully enter new markets or that any such expansion will not adversely affect our results of operations. Failure to manage our growth effectively could have a material adverse effect on our business, future prospects, financial condition or results of operations, and could adversely affect our ability to successfully implement our business strategy. Also, if our growth occurs more slowly than anticipated or declines, our operating results could be materially adversely affected.

​

A significant portion of our loan portfolio is secured by real estate, and events that negatively impact the real estate market could hurt our business.

​

A significant portion of our loan portfolios are secured by real estate. As of December 31, 2021, approximately 80.4% of such loans had real estate as a primary or secondary component of collateral. The real estate collateral in each case provides an alternate source of repayment in the event of default by the borrower and may deteriorate in value during the time the credit is extended. There can be no assurance that our local markets will not experience another economic decline. A decline in local economic conditions may have a greater effect on our earnings and capital than on the earnings and capital of other financial institutions whose real estate loan portfolios are more geographically diverse. Deterioration in the real estate market could cause us to adjust our opinion of the level of credit quality in our loan portfolio. Such a determination may lead to an additional increase in our allowance for credit losses, which could also adversely affect our business, financial condition, and results of operations.

​

Our loan portfolio includes commercial and commercial real estate loans that may have higher risks.

​

Our commercial and commercial real estate loans at December 31, 2021 and 2020 were $18.2 billion and $18.8 billion, respectively, or 76%, of total loans. Commercial and commercial real estate loans generally carry larger loan balances and can involve a greater degree of financial and credit risk than other loans. The increased financial and credit risk associated with these types of loans are a result of several factors, including the concentration of principal in a limited number of loans and borrowers, the size of loan balances, the effects of general economic conditions on income-producing properties and the increased difficulty of evaluating and monitoring these types of loans.

As a result, banking regulators give greater scrutiny to lenders with a high concentration of commercial real estate loans in their portfolios, and such lenders are expected to implement stricter underwriting, internal controls, risk management policies and portfolio stress testing, as well as maintain higher capital levels and loss allowances. The Guidance states that the following metrics may indicate a concentration of commercial real estate loans, but that these metrics are neither limits nor a safe harbor:

| 1) | total reported loans for construction, land development, and other land equal 100% or more of total risk based capital (as of December 31, 2021, our bank ratio was 55%); and

| 2) | total reported loans secured by multifamily and non-farm nonresidential properties and loans for construction, land development, and other land equal 300% or more of total risk-based capital (as of December 31, 2021, our bank ratio was 239%).

Regulators may require banks to maintain elevated levels of capital or liquidity due to commercial real estate loan concentrations, and could do so, especially if there is a downturn in our local real estate markets. See Part I Item 1. “Supervision and Regulation – Lending Standards and Guidance” for further details on the Guidance.

Furthermore, the repayment of loans secured by commercial real estate is typically dependent upon the successful operation of the related real estate or commercial project. If the cash flows from the project are reduced, a borrower’s ability to repay the loan may be impaired. This cash flow shortage may result in the failure to make loan payments. In such cases, we may be compelled to modify the terms of the loan. In addition, the nature of these loans is such that they are generally less predictable and more difficult to evaluate and monitor. As a result, repayment of these

loans may, to a greater extent than residential loans, be subject to adverse conditions in the real estate market or economy.

We may not be able to adequately anticipate and respond to changes in market interest rates.

We may be unable to anticipate changes in market interest rates, which are affected by many factors beyond our control including but not limited to inflation, recession, unemployment, money supply, monetary policy, and other changes that affect financial markets both domestic and foreign. Our net interest income is affected not only by the level and direction of interest rates, but also by the shape of the yield curve and relationships between interest sensitive instruments and key driver rates, as well as balance sheet growth, customer loan and deposit preferences, and the timing of changes in these variables. In the event rates increase, our interest costs on liabilities may increase more rapidly than our income on interest earning assets, thus a deterioration of net interest margins. As such, fluctuations in interest rates could have significant adverse effects on our financial condition and results of operations.

Our net interest income may decline based on the interest rate environment.

We depend on our net interest income to drive our profitability. Net interest income is the difference between the interest income we receive from interest earning assets (e.g., loans and investment securities) and the interest expense we pay on interest-bearing liabilities (e.g., deposits and borrowings). We are exposed to changes in general interest rate levels and other economic factors beyond our control, and an increase in our cost of funds could negatively impact our net interest income. Net interest income will decline in a particular period if:

| • | in a declining interest rate environment, more interest earning assets than interest bearing liabilities re price or mature, or

| • | in a rising interest rate environment, more interest-bearing liabilities than interest earning assets re price or mature, or

| • | for acquired loans, expected total cash flows decline as our loan balances decline.

Our net interest income may decline based on our exposure to a difference in short term and long term interest rates. If the difference between the interest rates shrinks or disappears, the difference between rates paid on deposits and received on loans could narrow significantly resulting in a decrease in net interest income. In addition to these factors, if market interest rates rise rapidly, interest rate adjustment caps may limit increases in the interest rates on adjustable rate loans, thus reducing our net interest income. In addition, certain adjustable rate loans re price based on lagging interest rate indices. This lagging effect may also negatively impact our net interest income when general interest rates continue to rise periodically.

While interest rates remain low, the Federal Reserve is expected to begin slowly raising interest rates during 2022. We cannot predict the nature or timing of future changes in monetary policies or the precise effects that they may have on our activities and financial results.

In addition, our net interest income may be adversely affected by inflationary pressures and global supply chain challenges. In part because the global supply chain has been drastically disrupted during the pandemic and remains challenged as it adapts and responds, inflation has exceeded the Federal Reserve’s two percent (2%) annual target. There is a risk that inflation may become higher or persist for longer periods of time and not decrease even as supply chain issues are resolved. While loan demand has increased during the second half of 2021, any increase in interest rates to address inflationary pressures could result in declines in demand for our banking products and services and could negatively impact, among other things, our liquidity, regulatory capital, goodwill and our growth strategy.

If we fail to effectively manage credit risk and interest rate risk, our business and financial condition will suffer.

We must effectively manage credit risk. There are risks inherent in making any loan, including risks with respect to the period of time over which the loan may be repaid, risks relating to proper loan underwriting and guidelines, risks resulting from changes in economic and industry conditions, risks inherent in dealing with individual borrowers and risks resulting from uncertainties as to the future value of collateral. There is no assurance that our credit risk monitoring and loan approval procedures are or will be adequate or will reduce the inherent risks associated with lending. Our credit administration personnel, policies and procedures may not adequately adapt to changes in economic

27

Table of Contents

or any other conditions affecting customers and the quality of our loan portfolio. Any failure to manage such credit risks may adversely affect our business, financial condition, and results of operations.

We must also effectively manage interest rate risk. Because mortgage loans typically have much longer maturities than deposits or other types of funding, rising interest rates can raise the cost of funding relative to the value of the mortgage loan. We manage this risk in part by holding adjustable rate mortgages in portfolios and through other means. Conversely, the value of our mortgage servicing assets may fall when interest rates fall, as borrowers refinance into lower rate loans. Given current rates, material reductions in rates may not be probable, but as rates rise, this risk increases. There can be no assurance that we will successfully manage the lending and servicing businesses through all future interest rate environments.

The results of our most recent stress tests may not accurately predict the impact on our financial condition if the economy were to deteriorate.

We perform capital stress testing on an annual basis using the stress testing assumptions provided by the regulators for the CCAR stress tests. We perform liquidity stress testing and credit stress testing on a quarterly basis. Under the capital stress test, we estimate our loan losses (loan charge-offs), resources available to absorb those losses and any necessary additions to capital that would be required under the “more adverse” stress test scenario. The results of these stress tests involve many assumptions about the economy and future loan losses and default rates, and may not accurately reflect the impact on our financial condition if the economy were to deteriorate. Any deterioration of the economy could result in credit losses significantly higher, with a corresponding impact on our financial condition and capital, than those predicted by our internal stress test.

Our size and continued pace of growth may require us to raise additional capital in the future, but that capital may not be available when it is needed.

We are required by federal and state regulatory authorities to maintain adequate levels of capital to support our operations. Our ability to raise capital, if needed, in the future to meet capital requirements or otherwise will depend on conditions in the capital markets at that time, which are outside our control, and on our financial performance. Accordingly, there is no assurance as to our ability to raise additional capital if needed on terms acceptable to us. If we cannot raise additional capital when needed, our ability to further expand our operations through internal growth and acquisitions could be materially impaired.

Our processes for managing risk may not be effective in mitigating risk or losses to us.

The objectives of our risk management processes are to mitigate risk and loss to our organization. We have established an enterprise risk framework and program that are intended to identify, measure, monitor report and analyze the types of risks to which we are subject, including liquidity risk, credit risk, market risk, interest rate risk, operational risk, cybersecurity risk, corporate governance and legal risk, compliance risk, and reputational risk, among others. However, this framework will evolve as we expect to become subject to heightened expectations from the OCC as we grow above $50 billion in assets. In addition, as with any risk management process, there are inherent limitations to our risk management strategies as there may exist, or develop in the future, risks that we have not appropriately anticipated or identified. The ongoing developments in the financial institutions industry continue to highlight both the importance and some of the limitations of managing unanticipated risks. If our risk management processes prove ineffective, we could suffer unexpected losses and could be materially adversely affected.

The continued buildout of our mortgage line of business may subject us to additional risk.

We continued to build our mortgage line of business in 2021, and in so doing, invested significant time and resources to continue to expand the mortgage business within our market areas. Our price and profitability targets for this business may not prove feasible, due to unexpected delays in the continued implementation of these strategies, as well as external factors, such as compliance with regulations, competitive alternatives, changing tax rates and strategies, interest rates, economic conditions, the continuance of the COVID-19 pandemic, and shifting market preferences, which could impact the profitability of these lines of business and have a material adverse effect on our businesses, and, in turn, our financial condition and results of operations.

Our recent results may not be indicative of our future results.

28

Table of Contents

We may not be able to sustain our historical rate of growth or may not even be able to grow our business at all. In addition, our recent growth may distort some of our historical financial ratios and statistics. Various factors, such as economic conditions, regulatory and legislative considerations and competition, may also impede or prohibit our ability to expand our market presence. If we experience a significant decrease in our historical rate of growth, our results of operations and financial condition may be adversely affected due to a high percentage of our operating costs being fixed expenses.

We are subject to environmental risks in our lending activities.

Because a significant portion of our loan portfolio is secured by real property, we may foreclose upon and take title to such property in the ordinary course of business. If hazardous substances were discovered on any of these properties, we may be liable to governmental agencies or third parties for the full costs of remediation, as well as for related personal injury and property damage. Environmental laws might require us to incur substantial expenses, materially reduce the property’s value, or limit our ability to use or sell the property. Although our management has policies requiring environmental reviews before loans secured by real property are made and before foreclosure is commenced, it is still possible that environmental risks might not be detected and that the associated costs might have a material adverse effect on our financial condition and results of operations. Many environmental laws impose liability regardless of whether the Company knew of, or were responsible for, the contamination. In addition, banks credit and underwriting policies that result in funding fossil fuel projects may impact climate change and lead to increased green house gas emissions. Banks have very limited control over the actions of their clients, and while banks can monitor client emissions and environmental profiles, information currently available is insufficient to assess both climate risk and the financial risk inherent in making lending decisions. Accordingly, the Bank may be unable to assess how our lending decisions affect both our risk profile and our profitability as well as our client’s efforts to address climate change.

While we use appraisals in deciding whether to make a loan that is secured by real estate, they do not ensure the value of the real property collateral.

​

In deciding whether to make a loan secured by real property, we generally require an appraisal. However, an appraisal is only an estimate of the value of the property at the time the appraisal is made. If the appraised amount does not reflect the amount that may be obtained upon any sale or foreclosure of the property, we may not realize an amount equal to the indebtedness secured by the property.

We are subject to losses due to errors, omissions or fraudulent behavior by our employees, clients, counterparties or other third parties.

We are exposed to many types of operational risk, including the risk of fraud by third parties, customers and employees, clerical recordkeeping errors and transactional errors. Like the financial services industry overall, we have seen an increase in fraudulent attempts on debit cards, and accounts during 2021 in part due to the material increase in online, including “card not present” transactions during the COVID-19 pandemic. While our procedures are designed to follow customary, industry-specific security precautions and while we provide employees with ongoing training, table-top exercises and regular communications and guidance to combat fraud, our efforts might not be successful in mitigating or reducing fraudulent attempts resulting in financial losses, increased litigation risk and reputational harm.

Our business also is dependent on our employees as well as third-party service providers to process a large number of increasingly complex transactions. We could be materially and adversely affected if employees, clients, counterparties or other third parties caused an operational breakdown or failure, either as a result of human error, fraudulent manipulation or purposeful damage to any of our operations or systems.

In deciding whether to extend credit or enter into other transactions with clients and counterparties, we may rely on information furnished to us by or on behalf of clients and counterparties, including financial statements and other financial information. We also may rely on representations of clients and counterparties as to the accuracy and completeness of that information and, with respect to financial statements, on reports of independent auditors. For example, in deciding whether to extend credit to clients, we may assume that a customer’s audited financial statements conform to GAAP and present fairly, in all material respects, the financial condition, results of operations and cash flows of the customer. Our earnings are significantly affected by our ability to properly originate, underwrite and service loans. Our financial condition and results of operations could be negatively impacted to the extent we incorrectly assess the creditworthiness of our borrowers, fail to detect or respond to deterioration in asset quality in a timely manner, or

29

Table of Contents

rely on financial statements that do not comply with GAAP or are materially misleading.

We are subject to environmental, social and governance (“ESG”) risks that could adversely affect our reputation, the trading price of our common stock and/or our business, operations, and earnings.

Governments, investors, customers, and the general public are increasingly focused on ESG practices and disclosures. For us and others in the financial services industry, this focus extends to the practices and disclosures of the customers, counterparties, and service providers with whom we choose to do business. In addition, certain organizations that provide corporate governance and other corporate risk information to investors and shareholders have developed scores and ratings to evaluate companies based upon ESG metrics. Currently, there are no universal standards for such scores or ratings, but the importance of ESG evaluations is becoming more broadly accepted by investors and shareholders. Views about ESG are diverse, dynamic, and rapidly changing, and if we were to fail to maintain appropriate ESG practices and disclosures or be subject to a low ESG score or rating, we could face potential negative ESG-related publicity in traditional and social media, including based on the identity of those we choose to do business with and the public’s view of those customers. If we or our relationships with customers, vendors and suppliers were to become the subject of such negative publicity or low ESG scores or ratings, our ability to attract and retain customers and employees may be negatively impacted and our stock price may also be impacted.

Additionally, investors have begun to consider how corporations are addressing ESG matters when making investment decisions. For example, certain investors are beginning to incorporate the business risks of climate change and the adequacy of companies’ responses to climate change and other ESG matters as part of their investment theses. Any such negative publicity regarding ESG, low ESG scores or ratings, or shifts in investing priorities may result in adverse effects on the trading price of our common stock and/or our business, operations and earnings if investors, shareholders or other stakeholders determine that we have not adequately considered or addressed ESG matters.

A lack of liquidity could affect our operations and jeopardize our financial condition.

Liquidity is essential to our business. An inability to raise funds through deposits, borrowings, the sale of loans and other sources could have a substantial negative effect on our liquidity. Our funding sources include core deposits, federal funds purchased, securities sold under repurchase agreements, non-core deposits, and short- and long-term debt. Other sources of liquidity are available to us should they be needed, including our ability to acquire additional non-core deposits, the issuance and sale of debt securities, a secured line of credit we have with U.S. Bank, and the issuance and sale of preferred or common securities in public or private transactions. Our access to funding sources in amounts adequate to finance or capitalize our activities or on terms that are acceptable to us could be impaired by factors that affect us specifically or the financial services industry or economy in general. Our ability to borrow could be impaired by factors that are not specific to us, such as further disruption in the financial markets or negative views and expectations about the prospects for the financial services industry in light of the recent turmoil faced by banking organizations and the continued deterioration in credit markets.

Our business could suffer if we fail to maintain our culture and attract and retain skilled people.

Our success depends, in large part, on our ability to attract and retain competent, experienced people. Our strategic goals in particular require that we be able to attract qualified and experienced retail and commercial lending officers, mortgage loan officers, and SBA lenders in our existing markets as well as those markets in which we may want to expand who share our relationship banking philosophy and have those customer relationships that will allow us to grow successfully. We also need to attract and retain qualified and experienced technology, risk and back-office personnel to operate our business. Many of our competitors are pursuing the same relationship banking strategy in our markets and are looking to hire and retain qualified technology, risk and back-office personnel, which increases the competition to identify, hire and retain talented employees.

The CenterState Merger and the integration of the Company’s and CenterState’s operations and employees into one bank creates an additional risk to the Company’s culture. If we fail to consider and account for corporate cultural differences across the two companies, we will face increased difficulty in creating a cohesive culture upon integration. The ongoing COVID-19 pandemic has made this cultural integration more challenging as many employees continue working from remote environments, which has drastically decreased the opportunities for employees to gather and nurture relationships with colleagues in different departments, locations or legacy institutions.

We have focused, and will continue to focus, our strategic attention on our employees and our corporate culture, including enhancing our employee orientation, ongoing general and management training, mentoring and employee work environment as well as diversity and employee advancement. Our failure to maintain our culture and attractive working environment, through competitive compensation packages that reward initiative, as well as mentoring, training, and advancement opportunities in order to successfully compete for experienced, qualified employees may have an adverse effect on our ability to meet our financial goals and thus adversely affect our future results of operations.

If we are unable to offer our key management personnel long term incentive compensation, including restricted stock units and performance share units, as part of their total compensation package, we may have difficulty retaining such personnel, which would adversely affect our operations and financial performance.

We have a management team that has substantial experience in banking and financial services in the markets we serve. We rely on our management team to achieve and sustain our profitability. Our future success and profitability are substantially dependent upon this management and banking abilities of our senior executives. Although we currently have employment agreements in place with our executive management team and our regional presidents, we cannot guarantee that our executives will remain with us. Changes in key personnel and their responsibilities may be disruptive to our business because of their skills, customer relationship and/or the potential difficulty of promptly replacing them with successors.

We have historically granted equity awards under an equity compensation plan, which includes granting performance share units and restricted stock awards or restricted stock units, to key management personnel as part of a competitive compensation package. Our ability to grant these awards has been vital to attracting, retaining and aligning shareholder interest with a talented management team in a highly competitive marketplace.

Shareholder advisory groups have implemented guidelines and issued voting recommendations related to how much equity companies should be able to grant to employees. The factors used to formulate these guidelines and voting recommendations include the volatility of a company’s share price and are influenced by broader macroeconomic conditions that can change year to year. The variables used by shareholder advisory groups to formulate equity plan recommendations may limit our ability to adopt new equity plans in the future. In addition, the federal banking regulators have issued guidance on executive compensation and have also, along with the SEC, proposed rules that would prohibit certain incentive compensation arrangements. We do not believe that the guidance or proposal will impact our current compensation arrangements.

If we are limited in our ability to grant equity compensation awards, we would need to explore offering other compelling alternatives to supplement our compensation, including long-term cash compensation plans or significantly increased short-term cash compensation, in order to continue to attract and retain key management personnel. If we used these alternatives to long-term equity awards, our compensation costs could increase and our financial performance could be adversely affected. If we are unable to offer key management personnel long-term incentive compensation, including stock options, restricted stock or restricted stock units, or performance share units, as part of their total compensation package, we may have difficulty attracting and retaining such personnel, which would adversely affect our operations and financial performance.

We rely on the performance of highly skilled personnel and if we are unable to attract, retain, develop and motivate our human capital in the form of well-qualified employees, our business and results of operations could be harmed.

We believe our success has depended, continues to and in the future will, depend, on the efforts and talents of our management team and our highly skilled employees and workers. Our future success depends on our continuing ability to attract, develop, motivate and retain highly qualified and skilled employees. The loss of any of our senior management or key employees could materially and adversely affect our ability to build on the efforts that they have undertaken and to execute our business plan, and we may not be able to find adequate replacements. Despite our current efforts, we cannot ensure that we will be able to retain the services of any members of our senior management or other key employees. If we do not succeed in attracting well-qualified employees or developing, retaining and motivating our employees, our business and results of operations could be harmed.

We rely on other companies to provide key components of our business infrastructure.

Third parties provide key components of our business infrastructure, such as our loan and deposit documents, underwriting software, compliance software, product and service offerings, core processing, and internet connections and network access. Any disruption in such services provided by these third parties or any failure of these third parties to handle currently or higher volumes of use could adversely affect our ability to deliver products and services to our clients and otherwise to conduct business. Technological or financial difficulties of one or our third-party service providers or their sub-contractors could adversely affect our business to the extent those difficulties result in the interruption or discontinuation of services provided by that party. In addition, one or more of our third-party service providers may become subject to cyber-attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss of destruction of our or our client’s confidential, proprietary and other information, or otherwise disrupt our or our clients’ or other third parties’ business operations. While we have processes in place to monitor our third-party service providers’ data and information security safeguards, we do not control such service providers’ day to day operations and a successful attack or security breach at one or more of such third-party service providers is not within our control. The occurrence of any such breaches or failures could damage our reputation, result in a loss of customer business, and expose us to additional regulatory scrutiny, civil litigation, and possible financial liability, any of which could have a material adverse effect on our financial condition and results of operations. Further, in some instances we may be responsible for the failure of such third parties to comply with government regulations, and our business recovery plan may not be adequate and may not prevent significant interruptions of our operations or substantial losses. We may not be insured against all types of losses as a result of third-party failures and our insurance coverage may not be inadequate to cover all losses resulting from system failures, third-party breaches, or other disruptions. Failures in our business structure or in the structure of one or more of our third-party service providers could interrupt the operations or increase the cost of doing business.

A failure and/or breach of our operational or securities systems or infrastructure, or those of our third-party vendors and other service providers, including as a result of cyber-attacks, could disrupt our business, result in a disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs and cause losses.

The potential for operational risk exposure exists throughout our business and, as a result of our interactions with, and reliance on, third parties, is not limited to our own internal operational functions. We depend on our ability to process, record and monitor a large number of client transactions on a continuous basis. As client, public and regulatory expectations regarding operational and information security have increased, we must continue to safeguard and monitor our operational systems and infrastructure for potential failures, disruptions and breakdowns. Our business, financial, accounting, data processing, or other operating systems and facilities may stop operating properly or become disabled or damaged as a result of a number of factors including events that are wholly or partially beyond our control. Although we have information and data security, business continuity plans and other safeguards in place, our business operations may be adversely affected by significant and widespread disruption to our physical infrastructure or operating systems that support our businesses and clients.

We rely on our employees and third parties in our day-to-day and ongoing operations, who may, as a result of human error, misconduct, malfeasance or failure, or breach of our or of third-party systems or infrastructure, expose us to risk. For example, our ability to conduct business may be adversely affected by any significant disruptions to us or to third parties with whom we interact or upon whom we rely. In addition, our ability to implement backup systems and other safeguards with respect to third-party systems is more limited than with respect to our own systems. Our financial, accounting, data processing, backup or other operating or security systems and infrastructure may fail to operate properly or become disabled or damaged as a result of a number of factors, including events that are wholly or partially beyond our ability to control, which could adversely affect our ability to process transactions or provide services. Such events may include: sudden increases in customer transaction volume; electrical, telecommunications or other major physical infrastructure outages; natural disasters such as earthquakes, tornadoes, hurricanes and floods; disease pandemics; and events arising from local or larger scale political or social matters, including wars and terrorist acts. In addition, we may need to take our systems offline if they become infected with malware or a computer virus or as a result of another form of cyber-attack. In the event that backup systems are utilized, they may not process data as quickly as our primary systems and some data might not have been saved to backup systems, potentially resulting in a temporary or permanent loss of such data. We frequently update our systems to support our operations and growth and to remain compliant with all applicable laws, rules and regulations. This updating entails significant costs and creates risks associated with implementing new systems and integrating them with existing ones, including business interruptions. Implementation and testing of controls related to our computer systems, security monitoring and retaining

32

Table of Contents

and training personnel required to operate our systems also entail significant costs. Operational risk exposures could adversely impact our results of operations, liquidity and financial condition, as well as cause reputational harm. In addition, we may not have adequate insurance coverage to compensate for losses from a major interruption.

Any failure or interruption in the operation of our communications and information systems could impair or prevent the effective operation of our customer relationship management, general ledger, deposit, lending or other functions. While we have policies and procedures designed to prevent or limit the effect of a failure or interruption in the operation of our information systems, there could be no assurance that any such failures or interruptions will not occur or, if they do, that they will be adequately addressed. The occurrence of any failures or interruptions impacting our information systems could damage our reputation, result in a loss of customer business, and expose us to additional regulatory scrutiny, civil litigation, and possible financial liability, any of which could have a material adverse effect on our financial condition and results of operations.

We face security risks, including denial of service attacks, hacking, social engineering attacks targeting our colleagues and customers, malware intrusion or data corruption attempts, and identity theft that could result in the disclosure of confidential information, adversely affect our business or reputation, and create significant legal and financial exposure.

Our computer systems and network infrastructure and those of third parties, on which we are highly dependent, are subject to security risks and could be susceptible to cyber-attacks, such as denial of service attacks, hacking, terrorist activities or identity theft. Our business relies on the secure processing, transmission, storage and retrieval of confidential, proprietary and other information in our computer and data management systems and networks, and in the computer and data management systems and networks of third parties. In addition, to access our network, products and services, our customers and other third parties may use personal mobile devices or computing devices that are outside of our network environment and are subject to their own cybersecurity risks.

We, our customers, regulators and other third parties, including other financial services institutions and companies engaged in data processing, have been subject to, and are likely to continue to be the target of, cyber-attacks. These cyber-attacks include computer viruses, malicious or destructive code, phishing attacks, denial of service attacks, ransomware, improper access by employees or vendors, attacks on personal email of employees, ransom demands to not expose security vulnerabilities in our systems or the systems of third parties or other security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of confidential, proprietary and other information of ours, our employees, our customers or of third parties, damage our systems or otherwise materially disrupt our or our customers’ or other third parties’ network access or business operations. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities or incidents. Despite efforts to ensure the integrity of our systems and implement controls, processes, policies and other protective measures, we may not be able to anticipate all security breaches, nor may we be able to implement guaranteed preventive measures against such security breaches. Cyber threats are rapidly evolving and we may not be able to anticipate or prevent all such attacks and could be held liable for any security breach or loss.

Cybersecurity risks for banking organizations have significantly increased in recent years, in part because of the proliferation of new technologies and the use of the internet and telecommunications technologies to conduct financial transactions. For example, cybersecurity risks may increase in the future as we continue to increase our mobile-payment and other internet-based product offerings and expand our internal usage of web-based products and applications. In addition, cybersecurity risks have significantly increased in recent years in part due to the increased sophistication and activities of organized crime affiliates, terrorist organizations, hostile foreign governments, disgruntled employees or vendors, activists and other external parties, including those involved in corporate espionage. Even the most advanced internal control environment may be vulnerable to compromise. Targeted social engineering attacks and "spear phishing" attacks are becoming more sophisticated and are extremely difficult to prevent. In such an attack, an attacker will attempt to fraudulently induce colleagues, customers or other users of our systems to disclose sensitive information in order to gain access to its data or that of its clients. Persistent attackers may succeed in penetrating defenses given enough resources, time, and motive. The techniques used by cyber criminals change frequently, may not be recognized until launched and may not be recognized until well after a breach has occurred. The risk of a security breach caused by a cyber-attack at a vendor or by unauthorized vendor access has also increased in recent years. Additionally, the existence of cyber-attacks or security breaches at third-party vendors with access to our data may not be disclosed to us in a timely manner.

33

Table of Contents

We also face indirect technology, cybersecurity and operational risks relating to the customers, clients and other third parties with whom we do business or upon whom we rely to facilitate or enable our business activities, including, for example, financial counterparties, regulators and providers of critical infrastructure such as internet access and electrical power. As a result of increasing consolidation, interdependence and complexity of financial entities and technology systems, a technology failure, cyber-attack or other information or security breach that significantly degrades, deletes or compromises the systems or data of one or more financial entities could have a material impact on counterparties or other market participants, including us. This consolidation, interconnectivity and complexity increases the risk of operational failure, on both individual and industry-wide bases, as disparate systems need to be integrated, often on an accelerated basis. Any third-party technology failure, cyber-attack or other information or security breach, termination or constraint could, among other things, adversely affect our ability to effect transactions, service our clients, manage our exposure to risk or expand our business. In addition, we, our employees and our customers, are increasingly transitioning our and their computing infrastructure to cloud-based computing, storage, data processing, networking and other services, which may increase these security risks.

Cyber-attacks or other information or security breaches, whether directed at us or third parties, may result in a material loss or have material consequences. Furthermore, the public perception that a cyber-attack on our systems has been successful, whether or not this perception is correct, may damage our reputation with customers and third parties with whom we do business. Hacking of personal information and identity theft risks, in particular, could cause serious reputational harm. A successful penetration or circumvention of system security could cause us serious negative consequences, including our loss of customers and business opportunities, significant business disruption to our operations and business, misappropriation or destruction of our confidential information and/or that of our customers, or damage to our or our customers’ and/or third parties’ computers or systems, and could result in a violation of applicable privacy laws and other laws, litigation exposure, regulatory fines, penalties or intervention, loss of confidence in our security measures, reputational damage, reimbursement or other compensatory costs, additional compliance costs, and could adversely impact our results of operations, liquidity and financial condition.

Although to date we have not experienced any material losses related to cyber-attacks or other information security breaches, there can be no assurance that we will not suffer such losses in the future.

We may face risks with respect to future expansion.

Our business growth, profitability and market share has been enhanced by us engaging in strategic mergers and acquisitions and de novo branching either within or contiguous to our existing footprint. We may acquire other financial institutions or parts of those institutions in the future and engage in additional de novo branching. We may also consider and enter into or acquire new lines of business or offer new products or services and through new sales channels, such as online and mobile banking. As part of our acquisition strategy, we seek companies that are culturally similar to us, have experienced management and are in markets in which we operate or close to those markets so we can achieve economies of scale.

We expect to continue to evaluate merger and acquisition opportunities that are presented to us in our current and expected markets and conduct due diligence related to those opportunities, as well as negotiate to acquire or merge with other institutions. If we announce a transaction, we may issue equity securities, including common stock and securities convertible into shares of our common stock in connection with future acquisitions. We also may issue debt to finance one or more transactions, including subordinated debt issuances. Generally, acquisitions of financial institution involve the payment of a premium over book and market values, resulting in dilution of our book value and fully diluted earnings per share, as well as dilution to our existing shareholders. We also face litigation risks with respect to potential mergers and acquisitions, and such litigation is common. We may incur substantial costs to expand, and we can give no assurance such expansion will result in the levels of profits we seek. There is no assurance that, following any future mergers or acquisitions, our integration efforts will be successful or our company, after giving effect to the acquisition, will achieve increased revenues comparable to or better than our historical experience, and failure to realize such expected revenue increases, cost savings, increases in market presence or other benefits could have a material adverse effect on our financial conditions and results of operations.

Attractive acquisition opportunities may not be available to us in the future.

While we seek continued organic growth, we anticipate continuing to evaluate merger and acquisition opportunities presented to us in our core markets and beyond. The number of financial institutions headquartered in our

34

Table of Contents

market areas in the Southeastern United States and across the country continues to decline through merger and other activity. We expect that other banking and financial companies, many of which have significantly greater resources, will compete with us to acquire financial services businesses. This competition, as the number of appropriate merger targets decreases, could increase prices for potential acquisitions which could reduce our potential returns, and reduce the attractiveness of these opportunities to us. In addition, acquisitions are subject to various regulatory approvals, and if we fail to receive the appropriate regulatory approvals, we will not be able to consummate an acquisition that we believe is in our best interests. Among other things, our regulators consider our capital, liquidity, profitability, risk management, regulatory compliance, including with respect to AML obligations, consumer protection laws, CRA obligations, and levels of goodwill and intangibles when considering acquisition and expansion proposals.

The standards by which bank and financial institution acquisitions will be evaluated are currently in flux and some banking organizations, including us, are experiencing delays in the processing of applications. In July 2021, President Biden issued an executive order on competition that requires the banking agencies to review the standards for bank mergers, and the DOJ has announced that it is reviewing its bank merger guidelines. It is expected that these reviews will tighten the standards for bank mergers and may change how the financial stability factor is evaluated. In addition, some in Congress have called for a moratorium of any bank merger and acquisition of greater than $100 billion in assets. While the Company is still much smaller in asset size than $100 billion, we cannot exclude that we may be subject to higher antitrust standards, enhanced scrutiny under the financial stability risk factor, or have a potential acquisition denied. Any acquisition could be dilutive to our earnings and shareholders’ equity per share of our common stock.

The transition from LIBOR to an alternative rate may adversely affect our business.

LIBOR and certain other interest rate benchmarks are the subject of recent national, international, and other regulatory guidance and proposals to reform. These reforms have caused and may in the future cause such benchmarks to perform differently than in the past, or to disappear entirely, or have other consequences which cannot be predicted.

The publication of most LIBOR rates ceased as of the end of December 2021. While certain U.S. dollar LIBOR tenors are expected to continue to be published until June 23, 2023, the U.S. federal banking agencies have encouraged banks to cease entering new contracts that use U.S. dollar LIBOR by December 31, 2021. The Bank discontinued the use of LIBOR in new contracts as of December 31, 2021. A transition away from the widespread use of LIBOR to alternative rates and other potential interest rate benchmark reforms has begun and will continue over the course of the next few years.

While there is no consensus on what rate or rates may become accepted alternatives to LIBOR, a group of large banks, the Alternative Reference Rate Committee, selected and the Federal Reserve Bank of New York began publishing in April 2018, the Secured Overnight Finance Rate (“SOFR”), as an alternative to LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by Treasury securities, given the depth and robustness of the U.S. Treasury repurchase market. On July 29, 2021, the ARRC announced that it is formally recommending CME Group’s forward-looking SOFR term rates. The bank has approved and is using SOFR term rates as an alternative to LIBOR in new contracts. While the use of SOFR term rates appears to have gained significant acceptance following the ARRC recommendation. at this time, it is impossible to predict whether other SOFR-based rates will become accepted alternatives to LIBOR.

The market transition away from LIBOR to an alternative reference rate, including SOFR, is complex and could have a range of adverse effects on our business, financial condition and results of operations. In particular, any such transition could:

| • | adversely impact the value of LIBOR-based securities, including certain of our floating rate corporate debentures or our hedging instruments, or other securities or financial arrangements given LIBOR’s role in determining market interest rates globally;

| • | although the Bank has implemented language in in its hedging and loan documents to accommodate a change from LIBOR to an alternative pricing benchmark, including SOFR, we may be required to make further changes to existing LIBOR-based products;

| • | prompt inquiries or other actions from regulators in respect of our preparation and readiness for the replacement of LIBOR with an alternative reference rate;

35

Table of Contents

| • | result in disputes, litigation or other actions with counterparties regarding the interpretation and enforceability of certain fallback language in LIBOR-based securities; and

| • | require the transition and/or development of appropriate systems and analytics to effectively transition our risk management processes from LIBOR-based products to those based on the applicable alternative pricing benchmark, such as SOFR.

The manner and impact of this transition, as well as the effect of these developments on our funding costs, loan and investment and trading securities portfolios, asset-liability management, and business, is uncertain.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in reports we file or submit with the SEC is accurately accumulated and communicated to management, and recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. We believe that any disclosure controls and procedures or controls and procedures, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control systems are met.

These inherent limitations include the reality that judgments and decision making can be faulty, that alternative reasoned judgments can be drawn, or that breakdowns can occur because of a simple error or mistake. Controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an authorized override of the controls. In addition, properly integrating our acquisitions into our disclosure controls and procedures in a timely manner presents challenges. Accordingly, because of the inherent limitations in our controls systems, misstatements due to error or fraud may occur and not be detected, which could result in a material weakness in our internal controls over financial reporting and the restatement of previously filed financial statements.

Our accounting policies and processes are critical to how we report our financial condition and results of operations and require our management to make estimates about matters that are uncertain.

Accounting policies and processes are fundamental to how we record and report our financial condition and results of operations. Some of these polices require use of estimates and assumptions that may affect the value of our assets or liabilities and financial results. Several of our accounting policies are critical because they require management to make difficult, subjective and complex judgments about matters that are inherently uncertain and because it is likely that materially different amounts would be reported under different conditions or using different assumptions. Pursuant to generally accepted accounting principles, we are required to make certain assumptions and estimates in preparing our financial statements, including and determining credit loss reserves, reserves related to litigation and the fair value of certain assets and liabilities, among other items. If the assumptions or estimates underling our financial statements are incorrect, we may experience material losses.

Certain of our financial instruments, including trading assets and liabilities, securities, and certain loans, among other items, require a determination of their fair value in order to prepare our financial statements. Where quoted market prices are not available, we may make fair value determinations based on internally developed models or other means which ultimately rely to some degree on management judgment. Some of these and other assets and liabilities may have no direct observable price levels, making their valuation particularly subjective, being based on significant estimation and judgment. In addition, some illiquidity in markets and declines in prices of certain loans and securities may make it more difficult to value certain balance sheet items, which may lead to the possibility that such valuations will be subject to further change or adjustment, it could lead to declines in our earnings.

As a participating lender in the SBA PPP, the Company and the Bank continue to be subject to the additional risks of litigation from the Bank’s customers or other parties regarding the Bank’s processing of loans and related forgiveness for the PPP and risks that the SBA may not fund some or all PPP loan guaranties.

Laws enacted during the pandemic included a loan program administered through the SBA referred to as the PPP. The SBA expanded this program in January 2021 to allow eligible companies that obtained loans through the first round of PPP to obtain additional loans, as well as allow eligible companies that had not yet obtained a loan under the PPP to do so. The Bank participated as a lender in two rounds of the PPP and we originated approximately $3.2 billion

36

Table of Contents

though the PPP program of which all but approximately 8%, or $263 million, excluding unamortized deferred fees and costs, has been forgiven. If PPP borrowers fail to qualify for loan forgiveness, the Bank faces a heightened risk of holding these loans at unfavorable interest rates for an extended period of time. While the PPP loans are guaranteed by the SBA, various regulatory requirements will apply to the Bank’s ability to seek recourse under the guarantees.

​

The Bank also has credit risk on outstanding PPP loans if a determination is made by the SBA that there is a deficiency in the manner in which the loan was originated, funded, or serviced by the Bank, such as an issue with the eligibility of a borrower to receive a PPP loan, which may or may not be related to the ambiguity in the laws, rules and guidance regarding the operation of the PPP. Such deficiency also may be found in the event the Bank discovers any evidence of fraud relating to a PPP loan. In the event of a loss resulting from a default on a PPP loan and a determination by the SBA that there was a deficiency in the manner in which the PPP loan was originated, funded, or serviced by the Company or evidence of fraud, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of any loss related to the deficiency from the Company. Incidents of borrower fraud in connection with PPP loans also might expose the Company to additional litigation risk, regulatory scrutiny and reputational damage, which could adversely affect our business, financial condition and operational results.

The value of securities in our investment portfolio may decline in the future.

As of December 31, 2021, we owned $7.2 billion of investment securities. The fair value of our investment securities may be adversely affected by market conditions, including changes in interest rates, and the occurrence of any events adversely affecting the issuer of particular securities in our investments portfolio. With adoption of Accounting Standards Codification (“ASC”) 326 effective January 1, 2020, we no longer evaluate securities for other-than-temporary impairments as the new accounting guidance changes the accounting for recognizing impairment on available for sale and held to maturity securities. We analyze our available for sale securities on a quarterly basis on an individual basis to determine if there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value. We consider the nature of the collateral, potential future changes in collateral values, default rates, delinquency rates, third-party guarantees, credit ratings, interest rate changes since purchase, volatility of the security’s fair value and historical loss information for financial assets secured with similar collateral among other factors. We use a systematic methodology to determine the ACL for investment securities held to maturity. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the held to maturity portfolio. We consider the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. Our estimate of the ACL involves a high degree of judgement; therefore, our process for determining expected credit losses my result in a range of expected credit losses. We monitor the held to maturity portfolio on a quarterly basis to determine whether a valuation account needs to be recorded. Because of changing economic and market conditions affecting issuers, we may be required to recognize expected credit losses on securities in future periods, which could have a material adverse effect on our business, financial condition or results of operations.

Consumers may decide not to use banks to complete their financial transactions.

Technology and other changes are allowing parties to complete financial transactions through alternative methods that historically have involved banks. For example, consumers can now maintain funds that would have historically been held as bank deposits in brokerage accounts, mutual funds or general purpose reloadable prepaid cards. Consumers can also complete transactions such as paying bills and/or transferring funds directly without the assistance of banks. The process of eliminating banks as intermediaries, known as “disintermediation,” could result in the loss of fee income, as well as the loss of customer deposits and the related income generated from those deposits. The loss of these revenue streams and the lower cost of deposits as a source of funds could have a material adverse effect on our financial condition and results of operations.

Our ability to maintain our reputation is critical to the success of our business, and the failure to do so may materially adversely affect our performance.

Our reputation is one of the most valuable components of our business. As such, we strive to conduct our business in a manner that enhances our reputation. This is done, in part, by recruiting, hiring, and retaining and providing growth opportunities for employees who share our core values of being an integral part of the communities we serve, delivering superior service to our customers, and caring about our customers and employees. If our reputation is

37

Table of Contents

negatively affected by the actions of our employees or otherwise, including as a result of a successful cyberattack against us or other unauthorized release or loss of customer information, our business and, therefore, our operating results, may be materially adversely affected.

Risks relating to the Regulatory Environment

We are subject to extensive regulation that could limit or restrict our activities.

We operate in a highly regulated industry and are subject to examination, supervision, and comprehensive regulation by various agencies, including the Federal Reserve, the OCC, CFPB and the FDIC. This regulation is imposed primarily to protect depositors, the FDIC deposit insurance fund, consumers, and the banking system as a whole. We also are regulated by the SEC and the Financial Industry Regulatory Authority, or FINRA, which regulation is designed to protect investors. Our compliance with these regulations is costly and potentially restricts certain of our activities, including payment of dividends, mergers and acquisitions, investments, loans and interest rates charged, interest rates paid and deposits and locations of our offices. We are also subject to capital guidelines established by our regulators, which require us to maintain sufficient capital to support our growth. Regulation of the financial services industry has increased significantly since the global financial crisis. The laws and regulations applicable to the banking industry could change at any time. The extent and timing of any regulatory reform as well as any effect on our business and financial results, are uncertain. Additionally, legislation or regulation may impose unexpected or unintended consequences, the impact of which is difficult to predict. Because government regulation greatly affects the business and financial results of all commercial banks and bank holding companies, our cost of compliance could adversely affect our ability to operate profitably.

In addition, we expect that the Biden Administration and the Democratically-controlled Congress will seek to implement a more stringent regulatory agenda that is focused on climate change and fair lending issues. This agenda could include a heightened focus on the regulation of loan portfolios and credit concentrations to borrowers impacted by climate change, heightened scrutiny on Bank Secrecy Act and anti-money laundering requirements, topics related to social equity, executive compensation, and increased capital and liquidity, as well as limits on share buybacks and dividends. In addition, mergers and acquisitions could be dampened by increased antitrust scrutiny. We also expect reform proposals for the short-term wholesale markets. It is too early for us to assess which, if any of these policies, would be implemented and what their impact on our business, financial condition or results of operations would be.

As the Company grows, the heightened expectations of regulatory agencies may expose us to additional regulatory risk.

As the Company grows above $50 billion in assets, the Company will be expected to bolster its risk management and governance framework to support a larger company. These expectations include established minimum standards for the design and implementation of the risk management framework and increased oversight and credible challenge by the board of directors over the Company’s risk profile and risk management practices. Our existing enterprise risk framework and program may not be easily scalable to meet such heightened expectations, thereby requiring lengthy or costly modifications to meet such expectations. Further, the Company’s existing workforce may not be sufficient or have the requisite skillset to design, operate and manage the bolstered framework, thereby requiring the Company to expend financial resources to hire and/or train the necessary staff. The Company’s failure to meet such heightened expectations may expose it to regulatory enforcement actions and civil penalties which could have an adverse material impact on the Company’s business, financial condition, operations and reputation and could jeopardize the Company’s ability to pursue acquisition opportunities.

We are required to maintain capital to meet regulatory requirements, and if we fail to maintain sufficient capital, whether due to losses, an inability to raise additional capital or otherwise, our financial condition, liquidity and results of operations, as well as our ability to maintain regulatory compliance, would be adversely affected.

The Company and the Bank each must meet regulatory capital requirements and maintain sufficient liquidity. Banking organizations experiencing growth, especially those making acquisitions, are expected to hold additional capital above regulatory minimums. From time to time, the regulators implement changes to these regulatory capital adequacy guidelines. In recent years, these market and regulatory expectations have increased substantially and have resulted in higher and more stringent capital requirements for us and the Bank. For example, current capital requirements disallow

38

Table of Contents

the Company’s trust preferred securities from qualifying as Tier 1 capital as a result of the Company exceeding $15 billion in assets.

Actions (if necessary) to increase capital, may adversely affect us. Our ability to raise additional capital, when and if needed, will depend on conditions in the capital markets, economic conditions and a number of other factors, including investor perceptions regarding the banking industry and market condition, and governmental activities, many of which are outside our control, and on our financial condition and performance. Accordingly, we cannot assure you that we will be able to raise additional capital if needed or on terms acceptable to us. If we fail to meet these capital and other regulatory requirements, our financial condition, liquidity and results of operations would be materially and adversely affected.

Our failure to remain “well capitalized” for bank regulatory purposes could affect customer confidence, our ability to grow, our costs of funds and FDIC insurance costs, our ability to pay dividends on common stock and make distributions on our trust preferred securities, our ability to make acquisitions, and our business, results of operations and financial condition. Under FDIC rules, if our subsidiary bank ceases to be a “well capitalized” institution for bank regulatory purposes, the interest rates that it pays and its ability to accept brokered deposits may be restricted. At December 31, 2021, we had approximately $325.0 million in wholesale brokered deposits, $52.0 million of in-market CDARs deposits, $848.1 million of ICS deposits and approximately $58.7 million of deposits related to our prepaid card business, which are considered brokered deposits for regulatory purposes.

We are subject to examination and scrutiny by a number of banking agencies and, depending upon the findings and determinations of these agencies, we may be required to make adjustments to our business that could adversely affect us.

The banking agencies regularly conduct examinations of our business, including compliance with applicable laws and regulations. If, as a result of an examination, a banking agency were to determine that the financial condition, capital resources, asset quality, asset concentration, earning prospects, management, liquidity, sensitivity to market risk, consumer compliance, or other aspects of any of our operations has become unsatisfactory, or that we or our management is in violation of any law or regulation, it could take a number or different remedial actions as it deems appropriate. These actions include the power to enjoin “unsafe or unsound” practices, to require affirmative actions to correct any conditions resulting from any violation or practice, to issue an administrative order that can be judicially enforced, to direct an increase in our capital, to restrict our growth, to change the asset composition of our portfolio or balance sheet, to assess civil money penalties against our officers or directors, to remove officers and directors and, if it is concluded that such conditions cannot be corrected or there is an imminent risk of loss to depositors, to terminate our deposit insurance. If we become subject to such regulatory actions, our business, results of operations and reputation may be negatively impacted.

The Bank is subject to the Bank Secrecy Act and other anti-money laundering statutes and regulations, and any deemed deficiency by the Bank with respect to these laws could result in significant liability and have material impact on our business strategy.

The Bank Secrecy Act, the USA PATRIOT Act of 2001, and other laws and regulations require financial institutions, among other duties, to institute and maintain an effective AML program and file suspicious activity and currency transaction reports when appropriate. The Bank is also subject to increased scrutiny of compliance with the rules enforced by OFAC regarding, among other things, the prohibition of transacting business with, and the need to freeze assets of, certain persons and organizations identified as a threat to the national security, foreign policy, or economy of the United States. Please see Item I – Part 1 – Supervision and Regulation - Anti-Money Laundering Rules and Item 1 – Part 1 – Supervision and Regulation - OFAC Regulation for further information regarding the Bank’s obligations under applicable AML laws and regulations and sanctions, respectively.

If the Bank’s policies, procedures, and systems are deemed deficient, or the policies, procedures and systems of the financial institutions that we have already acquired or may acquire in the future are deficient, the Bank could be subject to liability, including fines and regulatory actions, which may include restrictions on its ability to pay dividends and the necessity and ability to obtain regulatory approvals to proceed with certain aspects of its business plan, including acquisition plans. Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have serious reputational consequences for the Bank. Any of these results could have a material adverse effect on the Bank’s business, financial condition, results of operations, and future prospects.

39

Table of Contents

The Bank is subject to numerous laws designed to protect consumers, including the Community Reinvestment Act and fair lending laws, and failure to comply with these laws could lead to a material penalties and other sanctions.

The CRA, the Equal Credit Opportunity Act, the Fair Housing Act, and other fair lending laws and regulations impose nondiscriminatory lending requirements on financial institutions. The U.S. Department of Justice and other federal agencies are responsible for enforcing these laws and regulations. A successful regulatory challenge to an institution’s performance under the CRA or fair lending laws and regulations could result in a wide variety of sanctions, including damages and civil money penalties, injunctive relief, restrictions on mergers and acquisitions activity, restrictions on expansion, and restrictions on entering new business lines. Private parties may also have the ability to challenge an institution’s performance under fair lending laws in private class action litigation. Such actions could have a material adverse effect on the Bank’s business, financial condition, results of operations, and future prospects.

Higher FDIC deposit insurance premiums and assessments could adversely affect our financial condition.

The FDIC insures deposits at FDIC-insured depository institutions, such as our subsidiary Bank, up to applicable limits. The amount of a particular institution’s deposit insurance assessment is based on that institution’s risk classification under an FDIC risk-based assessment system. The assessment base on which the Bank’s deposit insurance premiums is paid to the FDIC has been calculated based on its average consolidated total assets less its average equity. However, effective January 1, 2019, which was following the fourth consecutive quarter where the Bank’s total consolidated assets exceeded $10 billion, the FDIC started to use a performance score and loss-severity score to calculate the Bank’s initial FDIC assessment rate. An institution’s risk classification is assigned based on its capital levels and the level of supervisory concern the institution poses to its regulators. While our risk management processes are designed to reduce risk by maintaining capital levels and mitigating any supervisory concerns, we may be unable to control the amount of premiums that we are required to pay for FDIC insurance in the event of a new economic downturn and an increase in financial institution failures. Any future increases in assessments or required prepayments in FDIC insurance premiums may materially adversely affect results of operations, including by reducing our profitability or limiting our ability to pursue business opportunities.

The Federal Reserve Board may require us to commit capital resources to support the Bank.

Applicable law and the Federal Reserve Board require a bank holding company to act as a source of financial and managerial strength to a subsidiary bank and to commit resources to support such subsidiary bank. Under the “source of strength” doctrine, the Federal Reserve Board may require a bank holding company to make capital injections into a troubled subsidiary bank and may charge the bank holding company with engaging in unsafe and unsound practices for failure to commit resources to such a subsidiary bank. Under these requirements, in the future, we could be required to provide financial assistance to our Bank if the Bank experiences financial distress.

A capital injection may be required at times when we do not have the resources to provide it, and therefore we may be required to borrow the funds. In the event of a bank holding company’s bankruptcy, the bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the holding company’s general unsecured creditors, including the holders of its note obligations. Thus, any borrowing that must be done by the holding company in order to make the required capital injection becomes more difficult and expensive and will adversely impact the holding company’s cash flows, financial condition, results of operations and prospects.

We could be subject to changes in tax laws, regulations and interpretations or challenges to our income tax provision.

We compute our income tax provision based on enacted tax rates in the jurisdictions in which we operate. Any change in enacted tax laws, rules or regulatory or judicial interpretations, or any change in the pronouncements relating to accounting for income taxes could adversely affect our effective tax rate, tax payments and results of operations. The taxing authorities in the jurisdictions in which we operate may challenge our tax positions, which could increase our effective tax rate and harm our financial position and results of operations. We are subject to audit and review by U.S. federal and state tax authorities. Any adverse outcome of such a review or audit could have a negative effect on our financial position and results of operations. In addition, changes in enacted tax laws, such as adoption of a lower income tax rate in any of the jurisdictions in which we operate, could impact our ability to obtain the future tax benefits represented by our deferred tax assets. In addition, the determination of our provision for income taxes and other

40

Table of Contents

liabilities requires significant judgment by management. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and could have a material adverse effect on our financial results in the period or periods for which such determination is made.

Risks relating to our Common Stock

State law and provisions in our articles of incorporation or bylaws could make it more difficult for another company to purchase us, even though such a purchase may increase shareholder value.

In many cases, shareholders may receive a premium for their shares if we were purchased by another company. State law and our articles of incorporation and bylaws could make it difficult for anyone to purchase us without the approval of our board of directors.

Our articles of incorporation provide that a merger, exchange or consolidation of the Company with, or the sale, exchange or lease of all or substantially all of our assets to, any person or entity (referred to herein as a “Fundamental Change”), must be approved by the holders of at least 80% of our outstanding voting stock if the board of directors does not recommend a vote in favor of the Fundamental Change. The articles of incorporation further provide that a Fundamental Change involving a shareholder that owns or controls 20% or more of our voting stock at the time of the proposed transaction (a “Controlling Party”) must be approved by the holders of at least (i) 80% of our outstanding voting stock, and (ii) 67% of our outstanding voting stock held by shareholders other than the Controlling Party, unless (a) the transaction has been recommended to the shareholders by a majority of the entire board of directors or (b) the consideration per share to be received by our shareholders generally is not less than the highest price per share paid by the Controlling Party in the acquisition of its holdings of our common stock during the preceding three years. The approval by the holders of at least 80% of our outstanding voting stock is required to amend or repeal these provisions contained in our articles of incorporation. Finally, in the event that any such Fundamental Change is not recommended by the board of directors, the holders of at least 80% of our outstanding voting stock must attend a meeting called to address such transaction, in person or by proxy, in order for a quorum for the conduct of business to exist. If the 80% and 67% vote requirements described above do not apply because the board of directors recommends the transaction or the consideration is deemed fair, as applicable, then pursuant to the provisions of the South Carolina Business Corporation Act, the Fundamental Change generally must be approved by two thirds of the votes entitled to be cast with respect thereto.

Consequently, a takeover attempt may prove difficult, and shareholders may not realize the highest possible price for their securities.

Shares of our Common Stock are not insured deposits and may lose value.

Shares of our common stock are not savings or deposit accounts and are not insured by the FDIC, or any other agency or private entity. Such shares are subject to investment risk, including the possible loss of some or all of the value of your investment.

Future capital needs could result in dilution of shareholder investment.

Our board of directors may determine from time to time there is a need to obtain additional capital through the issuance of additional shares of our common stock or other securities. These issuances would dilute the ownership interest of our shareholders and may dilute the per share book value of our common stock. New investors also may have rights, preferences and privileges senior to our shareholders which may adversely impact our shareholders.

The trading volume in our common stock and the sale of substantial amounts of our common stock in the public market could depress the price of our common stock.

We cannot predict the effect, if any, that future sales of our common stock in the market, or availability of shares of our common stock for sale in the market, will have on the market price of our common stock. Our stock price can fluctuate widely in response to a variety of factors. General market fluctuations, industry factors, and general economic and political conditions and events, such as terrorist attacks, economic slowdowns or recessions, interest rate changes, tax rate changes, credit loss trends, or currency fluctuations, also could cause our stock price to decrease

41

Table of Contents

regardless of operating results. We therefore can give no assurance that sales of substantial amounts of our common stock in the market, or the potential for large amounts of sales in the market, or any of the other factors discussed above, would not cause the price of our common stock to decline or impair our ability to raise capital through sales of our common stock.

Our ability to pay dividends is limited and we may be unable to pay future dividends.

Our ability to pay dividends is limited by regulatory restrictions and the need to maintain sufficient consolidated capital. The ability of the Bank to pay dividends to us is limited by its obligations to maintain sufficient capital and by other general restrictions on its dividends that are applicable to national banks that are regulated by the OCC. For information on these regulatory restrictions on the right of the Bank to pay dividends to us and on the right of the Company to pay dividends to its shareholders, see Part I - Item 1 – “Supervision and Regulation - Dividend Restrictions.” If we do not satisfy these regulatory requirements, or if the Bank does not have sufficient earnings to make payments to us while maintaining adequate capital levels, we will be unable to pay dividends on our common stock.

Holders of our junior subordinated debentures have rights that are senior to those of our common shareholders.

We have helped support our continued growth through the issuance of, and the acquisition of, through prior mergers, trust preferred securities from special purpose trusts and accompanying junior subordinated debentures. The Company redeemed $38.5 million of trust preferred securities in the second and third quarters of 2021, and as of December 31, 2021, we had outstanding trust preferred securities and accompanying junior subordinated debentures totaling $117.2 million, net of fair value adjustments. Payments of the principal and interest on these debt instruments are conditionally guaranteed by us. Further, the accompanying junior subordinated debentures we issued to the special purpose trusts are senior to our shares of common stock. As a result, we must make payments on the junior subordinated debentures before any dividends can be paid on our common stock and, in the event of our bankruptcy, dissolution or liquidation, the holders of the junior subordinated debentures must be satisfied before any distributions can be made on our common stock. We have the right to defer distributions on our junior subordinated debentures (and the related trust preferred securities) for up to five years, during which time no dividends may be paid on our common stock.

Our stock price may be volatile, which could result in losses to our investors and litigation against us.

Our stock price has been volatile in the past and several factors could cause the price to fluctuate substantially in the future. These factors include but are not limited to: actual or anticipated variations in earnings; changes in analysts’ recommendations or projections; our announcement of developments related to our businesses, operations and stock performance of other companies deemed to be peers; new technology used or services offered by traditional and non-traditional competitors; news reports of trends, concerns, irrational exuberance on the part of investors, and other issues related to the financial services industry. Our stock price may fluctuate significantly in the future, and these fluctuations may be unrelated to our performance. General market declines or market volatility in the future, especially in the financial institutions sector, could adversely affect the price of the Company’s common stock, and the current market price may not be indicative of future market prices.

Stock price volatility may make it more difficult for our investors to resell their common stock when they desire and at prices they find attractive. Moreover, in the past, securities class action lawsuits have been instituted against some companies following periods of volatility in the market price of its securities. We could in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert management’s attention and resources from our normal business.

At December 31, 2021, our shareholders included three funds owning approximately 24% of our common stock and they may exercise significant influence over us and their interests may be different from our other shareholders.

Based on their 13G forms filed for the year end December 31, 2021, our shareholders include three funds that collectively own approximately 24% of the outstanding shares of our common stock. Top ten institutional owners collectively own approximately 49% of our outstanding shares of common stock, as reported by S&P Global. While the federal banking laws require prior bank regulatory approval if shareholders owning in excess of 9.9% of a financial holding company’s outstanding voting shares desire to act in concert, these institutional owners nonetheless could vote the same way on matters submitted to our shareholders without being deemed to be acting in concert and, if so, could

42

Table of Contents

exercise significant influence over us and actions taken by our shareholders. Interests of institutional funds may be different from our other shareholders. Accordingly, given their collective ownership, the funds could have significant influence over whether or not a proposal submitted to our shareholders receives required shareholder approval.

Risks relating to Economic Conditions and other Outside Forces

The political and economic environment could materially impact our business operations and financial performance.

The political and economic environment in the United States and elsewhere has resulted in some uncertainty. Changing regulatory policies because of the changing political environment, including the Biden Administration and Democratically-controlled Congress, could be seen as increasing our regulatory and compliance costs, or decreases in the amount of expected revenues, all of which could materially and adversely affect our business, financial condition and operating results.

Additionally, financial markets may be adversely affected by the current or anticipated impact of military conflict, including escalating military tension between Russia and Ukraine, terrorism or other geopolitical events.

A slowdown in economic growth or a resumption of recessionary economic conditions could have an adverse effect on our business in the future.

The economic crisis of 2008 followed by the COVID-19 pandemic adversely affected the banking industry, as well as financial condition and operating results. Although economic conditions are improving and growth has been stronger during the second half of 2021, future political and market developments could affect consumer confidence levels and cause adverse changes in loan payment patterns, causing increases in delinquencies and default rates, which may impact our charge-offs and the provision for credit losses. For example, changes in international trade policy, combined with the outbreak of COVID-19, continues to disrupt global supply chains, and also has led to inflationary pressures on goods and services, as well as wages. These circumstances could adversely impact our customers and their customers, which in turn could impact their ability to make loan payments, with the impacts to our business listed above. Changes in the financial services industry and the effects of current and future law and regulations that may be imposed in response to future market developments also could negatively affect us by restricting our business operations, including our ability to originate or sell loans, and adversely impact our financial performance.

The soundness of other financial institutions could adversely affect us.

Our ability to engage in routine funding and other transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. Defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, have led to market-wide liquidity problems and losses of depositor, creditor and counterparty confidence and could lead to losses or defaults by us or by other institutions. We could experience increases in deposits and assets as a result of other banks’ difficulties or failure, which would increase the capital we need to support our growth.

Our business is subject to the success of the local economies where we operate.

Our success significantly depends upon the growth in population, income levels, deposits and housing starts in our primary and secondary markets. If the communities in which we operate do not grow or if prevailing economic conditions locally or nationally become challenging, our business may be adversely affected. We are less able than a larger institution to spread the risks of unfavorable local economic conditions across a large number of diversified economies. We cannot give any assurance we will continue to benefit from market growth or favorable economic conditions in our primary market areas if they do occur.

Adverse weather or manmade events could negatively affect our local economies or disrupt our operations, which would have an adverse effect on our business or results of operations.

Our market areas in Florida, South Carolina, North Carolina, Georgia, Virginia and Alabama are susceptible to hurricanes, tropical storms and related flooding and wind damage as well as tornados and other types of strong storms.

Table of Contents

These type of storms may increase in intensity because of changes in weather patterns and other factors including climate change. Such weather events and manmade events can disrupt operations, result in damage to properties and negatively affect the local economies in the markets where they operate. Storms during 2021 only minimally impacted our operations but we cannot predict whether or to what extent damage that may be caused by future natural disasters or manmade events will affect our operations or the economies in our current or future market areas. Such events could result in a decline in loan originations, a decline in the value or destruction of properties securing our loans, as well as our own properties, and an increase in delinquencies, bankruptcies, foreclosures or loan losses that could result in a higher level of non-performing assets, net charge-offs, and provision for loan losses. Our business or results of operations may be adversely affected by these and other negative effects of future hurricanes, tropical storms, tornados or other extreme weather events, including flooding and wind damage, or manmade events. Many of our customers have incurred significantly higher property and casualty insurance premiums on their properties located in our markets, which may adversely affect real estate sales and values in those markets.

We are subject to physical and financial risks associated with climate change and other weather and natural disaster impacts.

The current and anticipated effects of climate change are creating an increasing level of concern for the state of the global environment. As a result, political and social attention to the issue of climate change has increased. In recent years, governments across the world have entered into international agreements to attempt to reduce global temperatures, in part by limiting greenhouse gas emissions. Although the U.S. rejoined the Paris Agreement, effective as of February 19, 2021, and the U.S. Congress, state legislatures and federal and state regulatory agencies have continued to propose and advance numerous legislative and regulatory initiatives seeking to mitigate the effects of climate change, each of which may result in the imposition of taxes and fees, the required purchase of emission credits, and the implementation of significant operational changes, which may require us to expend significant capital and incur compliance, operating, maintenance and remediation costs. Given the lack of empirical data on the credit and other financial risks posed by climate change, it is impossible to predict how climate change may impact our financial condition and operations; however, as a banking organization, the physical effects of climate change on the Bank may present certain unique risks.

The physical risks of climate change include discrete events, such as flooding, hurricanes, tornadoes, and wildfires, and longer-term shifts in climate patterns, such as extreme heat, sea level rise, and more frequent and prolonged drought. Physical risks may alter the Company’s strategic direction in order to mitigate certain financial risks. A significant portion of our operations is located in the areas bordering the Gulf of Mexico and the Atlantic Ocean, regions that are susceptible to hurricanes, or in areas of the Southeastern U.S. that are susceptible to tornadoes and other severe weather events including severe droughts, floods, and sea level rise. Any of these, or any other severe weather event, could cause disruption to our operations and could have a material adverse effect on our overall business, results of operations or financial condition. We have taken certain preemptive measures that we believe will mitigate these adverse effects; however, such measures cannot prevent the disruption that a catastrophic earthquake, fire, hurricane, tornado or other severe weather event could cause to the markets that we serve and any resulting adverse impact on our customers, such as hindering our borrowers’ ability to timely repay their loans, diminishing the value of any collateral held by us, interrupting supply chains, causing significant property damage, causing us to incur additional expense or resulting in a loss of revenue, and affecting the stability of our deposit base. The severity and impact of future earthquakes, fires, hurricanes, tornadoes, droughts, sea level rise, floods and other weather-related events are difficult to predict and may be exacerbated by global climate change. Man-made disasters and other events connected with the Gulf of Mexico or Atlantic Ocean, such as oil spills, could have similar effects. Such events may also cause reductions in regional and local economic activity that may have an adverse effect on our customers, which could limit our ability to raise and invest capital in these areas and communities, each of which could have a material adverse effect on our financial condition and results of operations.

Climate change may worsen the frequency and severity of future earthquakes, fires, hurricanes, tornadoes, droughts, sea level rise, floods and other extreme weather-related events that could cause disruption to our business and operations. Chronic results of climate change such as shifting weather patterns could also cause disruption to our business and operations. Climate change may also result in new and/or more stringent regulatory requirements for the Company, which could materially affect the Company’s results of operations by requiring the Company to take costly measures to comply with any new laws or regulations related to climate change that may be forthcoming. New regulations, shift in customer behaviors, supply chain collapse or breakthrough technologies that accelerate the transition to a lower carbon economy may negatively affect certain sectors and borrowers in our loan portfolio, impacting their ability to timely repay their loans or decreasing the value of any collateral held by us.

Market volatility could adversely affect our operations or ability to access capital.

The capital and credit markets have experienced volatility and disruption from time to time during the past several years. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial condition or performance. If these periodic market disruptions and volatility continue or worsen, we may experience adverse effects, which may be material, on our ability to maintain or access capital and on our business, financial condition and results of operations.

Our cost of funds may increase as a result of general economic conditions, FDIC insurance assessments, interest rates and competitive pressures.

Our cost of funds may increase as a result of general economic conditions, FDIC insurance assessments, interest rates and competitive pressures. We have traditionally obtained funds principally through local deposits and we have a base of lower cost transaction deposits. Generally, we believe local deposits are a less expensive and more stable source of funds than other borrowings because interest rates paid for local deposits are typically lower than interest rates charged for borrowings from other institutional lenders and reflect a mix of transaction and time deposits, whereas brokered deposits typically are higher cost time deposits. Our costs of funds and our profitability and liquidity are likely to be adversely affected, if and to the extent we have to rely upon higher cost borrowings from other institutional lenders or brokers to fund loan demand or liquidity needs, and changes in our deposit mix and growth could adversely affect our profitability and the ability to expand our loan portfolio.

Competition from financial institutions and other financial service providers may adversely affect our profitability.

The banking business is highly competitive and we experience competition in our markets from many other financial institutions. We compete with commercial banks, credit unions, mortgage banking firms, consumer finance companies, securities brokerage firms, insurance companies, money market funds, and other mutual funds, as well as other super-regional, national and international financial institutions and fintech or e-commerce companies that operate in our primary market areas and elsewhere. Some of these competitors may have a long history of successful operation in our markets, greater ties to local businesses and more expansive banking relationships, as well as better established depositor bases. Competitors with greater resources or more advanced technology may possess an advantage by being capable of maintaining numerous and more convenient banking locations, easy to use and available mobile and computer apps or Internet platforms, operating more ATMs and conducting extensive promotional and advertising campaigns.

We compete with these institutions both in attracting deposits and in making loans. In addition, we have to attract our customer base from other existing financial institutions and from new residents. Many of our competitors are well-established, larger financial institutions and credit unions. While we believe we can and do successfully compete with these other financial institutions in our primary markets, we may face a competitive disadvantage as a result of our smaller size, lack of geographic diversification, sophisticated online or mobile applications, and inability to spread our marketing costs across a broader market. Although we compete by concentrating our marketing efforts in our primary markets with local advertisements, personal contacts, and greater flexibility and responsiveness in working with local customers, we can give no assurance this strategy will be successful.

The fiscal and monetary policies of the federal government and its agencies could have a material adverse effect on our earnings.

The Federal Reserve regulates the supply of money and credit in the U.S. as its policies determine in large part the cost of funds for lending and investing and return earned on those loans and investments, both of which affect our net interest margin. They can also materially decrease the value of financial assets we hold. Federal Reserve policies also can adversely affect borrowers, potentially increasing the risk that they may fail to repay their loans, or could result in volatile markets and rapid declining collateral values. Changes in Federal Reserve policies are beyond our control and difficult to predict. Accordingly, the impact of these changes on our activities and results of operations is difficult to predict.

We are or may become involved from time to time in suits, legal proceedings, information-gathering requests, investigations, and proceedings by governmental and self-regulatory agencies that may lead to adverse consequences.

Many aspects of the banking business involve a substantial risk of legal liability. The Company and the Bank

have been named or threatened to be named as defendants in various lawsuits arising from our business activities (and in some cases from the activities of companies that we have acquired). In addition, from time to time, we are, or may become, the subject of self-regulatory agency information-gathering requests, reviews, investigations and proceedings, and other forms of regulatory inquiry, including by bank regulatory agencies, the SEC and law enforcement authorities. The results of such proceedings could lead to significant civil or criminal penalties, including monetary penalties, damages, adverse judgments, settlements, fines, injunctions, restrictions on the way the Company and the Bank conduct their business, or reputational harm.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our corporate headquarters are located in a branch located at 1101 First Street South, Suite 202, Winter Haven, Florida 33880. Our bank owns 228 properties and leases 114 properties, of which most are used as branch locations, mortgage loan production offices, wealth offices or for housing operational units in Alabama, Florida, Georgia, North Carolina, South Carolina, and Virginia. We also operate a correspondent banking division within our national bank subsidiary, of which the majority of its bond salesmen, traders and operational personnel are housed in facilities located in Birmingham, Alabama and Atlanta, Georgia. In addition, we lease some space in California, New York and Texas related to the correspondent banking division, and occupy a space in Memphis, Tennessee related to DWI. Although the properties owned and leased are generally considered adequate, we have a continuing program of modernization, expansion, and when necessary, occasional replacement of facilities. For additional information relating to the Company’s premises, equipment and lease commitments, see Note 7—Premises and Equipment and Note 21—Lease Commitments to our audited consolidated financial statements.

Item 3. Legal Proceedings.

We or our bank subsidiary is periodically a party to or otherwise involved in legal proceedings arising in the normal course of business, such as claims to enforce liens, claims involving the making and servicing of real property loans, and other issues incident to our products and services and our businesses. We do not believe any pending or threatened legal proceedings in the ordinary course against the bank would have a material adverse effect on our consolidated results of operations or consolidated financial position.

Item 4. Mine Safety Disclosures.

Not applicable.

Dividends

We currently intend to continue to pay comparable quarterly cash dividends on our common stock, subject to approval by our Board of Directors, although we may elect not to pay dividends or to change the amount of such dividends. The payment of dividends is a decision by our Board of Directors based upon then-existing circumstances, including our rate of growth, profitability, financial condition, existing and anticipated capital requirements, the amount of funds legally available for the payment of cash dividends, regulatory constraints and such other factors as the Board of Directors determines relevant.

The Company is a legal entity separate and distinct from the Bank. Federal Reserve policy provides that bank holding companies, such as the Company, should generally pay dividends to shareholders only if (i) the organization’s net income available to common shareholders over the past year has been sufficient to fully fund the dividends; (ii) the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition; and (iii) the organization will continue to meet minimum capital adequacy ratios. The policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to the bank holding company’s capital structure. Bank holding companies also are required to consult with the Federal Reserve, who could prohibit or limit the payment of dividends by a bank holding company if it determines that payment of the dividend would constitute an unsafe or unsound practice.

We pay cash dividends to our shareholders from our assets, which are provided primarily by dividends paid to SouthState by our Bank. Certain restrictions exist regarding the ability of the Bank to transfer funds to SouthState in the form of cash dividends, loans or advances, as described under “Supervision and Regulation – Dividend Restrictions. Federal bank regulators have stated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsafe and unsound banking practice and that banking organizations should generally pay dividends only out of

current earnings. The approval of the OCC is required if the total of all dividends declared by the Bank in any calendar year exceeds the total of its net profits for that year combined with its retained net profits for the preceding two years, less any required transfers to surplus. During 2021, the Bank paid dividends to SouthState totaling $200.0 million. We used these funds and excess cash to pay our dividend to shareholders of $135.3 million, repurchase shares of our common stock on the open market totaling $146.4 million and redeem $63.5 million in trust preferred securities and subordinated debentures.

Repurchases of Equity Securities

On January 27, 2021, the Board of Directors of the Company approved the authorization of a new 3,5000,000 share Company stock repurchase plan (the “2021 Stock Repurchase Plan”). Shares of common stock under the 2021 Stock Repurchase Plan may be purchased periodically in open market transactions at prevailing market prices, in privately negotiated transactions, or by other means in accordance with federal securities laws. The actual means and timing of any purchases, target number of shares and prices or range of prices under the 2021 Stock Repurchase Plan were determined by us in our discretion and depended on a number of factors, including the market price of our common stock, share issuances under our equity plans, general market and economic conditions, and applicable legal and

regulatory requirements. In 2021, the Company repurchased a total of 1,817,941 shares for $146.4 million or $80.51 per share (excluding commission expense). U nder the 2021 Stock Repurchase Plan, we may repurchase up to an additional 1,682,059 shares of common stock under the program.

Introduction

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) describes SouthState Corporation and its subsidiary’s results of operations for the year ended December 31, 2021 as compared to the year ended December 31, 2020, and the year ended December 31, 2020 as compared to the year ended December 31, 2019, and also analyzes our financial condition as of December 31, 2021 as compared to December 31, 2020. Like most banking institutions, we derive most of our income from interest we receive on our loans and investments. Our primary source of funds for making these loans and investments is our deposits, on most of which we pay interest. Consequently, one of the key measures of our success is the amount of net interest income, or the difference between the income on our interest-earning assets, such as loans and investments, and the expense on our interest-bearing liabilities, such as deposits. Another key measure is the spread between the yield we earn on these interest-earning assets and the rate we pay on our interest-bearing liabilities.

There are risks inherent in all loans, so we maintain an allowance for credit losses to absorb our estimate of probable losses on existing loans that may become uncollectible. We establish and maintain this allowance by recording a provision or recovery for credit losses against our earnings. In the following section, we have included a detailed discussion of this process.

In addition to earning interest on our loans and investments, we earn income through fees and other services we charge to our customers. We incur costs in addition to interest expense on deposits and other borrowings, the largest of which is salaries and employee benefits. We describe the various components of this noninterest income and noninterest expense in the following discussion.

The following section also identifies significant factors that have affected our financial position and operating results during the periods included in the accompanying financial statements. We encourage you to read this discussion and analysis in conjunction with the financial statements and the related notes and the other information included in this Report.

Overview

SouthState Corporation is a financial holding company headquartered in Winter Haven, Florida, and was incorporated under the laws of South Carolina in 1985. We provide a wide range of banking services and products to our customers through our Bank. The Bank operates SouthState Advisory, Inc., a wholly owned registered investment advisor. The Bank also operates Duncan-Williams, Inc. (“Duncan-Williams”), which it acquired on February 1, 2021. Duncan-Williams is a registered broker-dealer, headquartered in Memphis, Tennessee, that serves primarily institutional clients across the U.S. in the fixed income business. The Bank also owns CBI Holding Company, LLC (“CBI”), which in turn owns Corporate Billing, LLC (“Corporate Billing”), a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide. The holding company also owns SSB Insurance Corp., a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code. The holding company also owned R4ALL, Inc., which managed troubled loans purchased from the Bank. During the third quarter of 2021, the final loan held by R4ALL, Inc. paid off, and the holding company subsequently dissolved R4ALL, Inc. effective October 29, 2021.

​

At December 31, 2021, we had $42.0 billion in assets and 5,036 full-time equivalent employees. Through our Bank branches, ATMs and online banking platforms, we provide our customers with a wide range of financial products and services, through a six (6) state footprint in Alabama, Florida, Georgia, North Carolina, South Carolina and Virginia. These financial products and services include deposit accounts such as checking accounts, savings and time deposits of various types, safe deposit boxes, bank money orders, wire transfer and ACH services, brokerage services and alternative investment products such as annuities and mutual funds, trust and asset management services, loans of all types, including business loans, agriculture loans, real estate-secured (mortgage) loans, personal use loans, home improvement loans, automobile loans, manufactured housing loans, boat loans, credit cards, letters of credit, home equity lines of credit, treasury management services, and merchant services.

​

We also operate a correspondent banking and capital markets division within our national bank subsidiary, of which the majority of its bond salesmen, traders and operational personnel are housed in facilities located in Birmingham, Alabama and Atlanta, Georgia. This division’s primary revenue generating activities are related to its capital markets division, which includes commissions earned on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities; and its correspondent banking division, which includes spread income earned on correspondent bank deposits (i.e., federal funds purchased) and correspondent bank checking account deposits and fees from safe-keeping activities, bond accounting services for correspondents, asset/liability consulting related activities, international wires, and other clearing and corporate checking account services. The correspondent banking and capital markets division was further expanded with the addition of Duncan-Williams on February 1, 2021.

​

We earned net income of $475.5 million, or $6.71 diluted earnings per share (“EPS”), during 2021 compared to net income of $120.6 million, or $2.19 diluted EPS, in 2020. Net income available to the common shareholders was up $354.9 million, or 294.2%, in 2021 compared to 2020. For further discussion of the Company’s results of operations for the year ended December 31, 2021 as compared to the year ended December 31, 2020, and the year ended December 31, 2020 as compared to the year ended December 31, 2019, see Results of Operations section of this MD&A starting on page 57.

​

At December 31, 2021, we had total assets of approximately $42.0 billion compared to approximately $37.8 billion at December 31, 2020. See the Financial Condition section of this MD&A starting on page 68 for a more detailed description of the change in our balance sheet.

​

Our asset quality results remained strong in 2021. For the year ended December 31, 2021, net charge offs as a percentage of average loans remained unchanged at 0.01% from the year ended December 31, 2020. The total Nonperforming Assets (“NPAs”) decreased $35.3 million to $83.7 million at December 31, 2021 from $119.1 million at December 31, 2020. Acquired NPAs decreased $29.4 million to $59.8 million at December 31, 2021 from $89.2 million

51

Table of Contents

at December 31, 2020. Acquired nonperforming loans decreased $20.7 million and acquired OREO and other nonperforming assets decreased $8.7 million. Non-acquired NPAs decreased $6.0 million to $23.9 million at December 31, 2021 from $29.9 million at December 31, 2020. This decline was mainly related to a decline in non-acquired nonperforming loans which fell by $5.9 million from December 31, 2020. Non-acquired OREO and other NPAs remained stable in 2021 and decreased $98,000. The total NPAs as a percentage of total assets decreased 12 basis points to 0.20% at December 31, 2021 as compared to 0.32% at December 31, 2020.

​

Our efficiency ratio was 65.6% at December 31, 2021 compared to 67.5% at December 31, 2020. The positive change in our efficiency ratio was due to the effect of the 22.0% increase in the total of net interest income and noninterest income being greater than the effect of the 18.5% increase in noninterest expense. The main reason for the increase in net interest income and noninterest income was due to the Company having a full year’s effect of the income in 2021 from the merger with CSFL that occurred in June 2020. The lower percentage increase in noninterest expense was mainly due to the cost saves recognized since the merger with CSFL.

​

We continue to remain well-capitalized with a total risk-based capital ratio of 13.56% and a Tier 1 leverage ratio of 8.05%, as of December 31, 2021, compared to 14.24% and 8.27%, respectively, at December 31, 2020. The total risk-based capital ratio decreased in 2021 as total risk-weighted assets increased $1.7 billion, or 6.5%, while total risk-based capital (excluding the change in accumulated other comprehensive income, or AOCI) grew by $50.6 million, or 1.4%. The decrease in the total risk-based capital ratio at the Company was due to the percentage increase in total risk-based capital being less than the percentage increase in total risk-based assets. The reason for the lower percentage increase in the total risk-based capital at the Company was due the redemption of $25.0 million in subordinated debt and $38.5 million in trust preferred securities during the second quarter of 2021 that was included in total risked-based capital along with the amount of allowance for credit losses eligible for capital purposes declining $77.3 million with the releases of provision in 2021. The Tier 1 leverage ratio decreased from the prior year as tier 1 capital (excluding the change in AOCI) increased by $191.5 million or 6.4%, while total average eligible assets increased $3.4 billion, or 9.3%. The Tier 1 leverage ratio declined as the percentage increase in Tier 1 risk-based capital was less than the percentage increase in the average assets for regulatory capital purposes. The increase in average assets was mainly due to an increase in cash and cash equivalents and investments from December 31, 2020 with deposits growing as the federal government has pushed funds into the market through stimulus programs, in addition to consumers remaining conservative in their spending habits. We believe our current capital ratios position us well to grow both organically and through certain strategic opportunities. For further discussion of the Company’s financial condition as of December 31, 2021 compared to December 31, 2020, see Financial Condition section of this MD&A starting on page 68.

COVID-19

Although the economy has been recovering from the COVID-19 pandemic and vaccine distributions and treatments are generally available, businesses throughout the United States and our customers are still being adversely affected by the COVID-19 pandemic. In many of the states in our market area, as the economies have been allowed to reopen, there has been an increase in cases of COVID-19 and several new variants of COVID-19 in 2021 that have caused cases to increase.

​

The impact of the COVID-19 pandemic is fluid and continues to evolve. The COVID-19 pandemic, and its associated impacts on trade (including supply chains and export levels), travel, employee productivity, unemployment, consumer spending, and other economic activities, initially resulted in less economic activity, lower equity market valuations and increased volatility and disruption in financial markets, and had an adverse effect on our business, financial condition and results of general operations, with a more limited impact to our correspondent banking and capital markets business lines. Those impacts declined as the economy reopened during the second half of 2021. However, the ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is uncertain and will depend on various developments and other factors, including, among others, an increase in cases as a result of new waves of the pandemic or as new variants of the disease begin to circulate, how federal, state and local governments and the private sector respond, and the associated impacts on the economy, financial markets and our customers, employees and vendors.

​

Our business, financial condition and results of operations generally rely upon the ability of our borrowers to repay their loans, the value of collateral underlying our secured loans, and demand for loans and other products and services we offer, which are highly dependent on the business environment in our primary markets where we operate and in the United States as a whole. The COVID-19 pandemic has had a significant impact on our business and operations.

As part of our efforts to practice social distancing, in March 2020, we closed all of our banking lobbies and began conducting most of our business through drive-thru tellers and through electronic and online means. To support the health and well-being of our employees, we allowed a majority of our non-customer facing workforce to work from home. In October 2020, we reopened our banking lobbies in our branch locations, but a majority of our support staff is still working from home. We anticipate the remaining support staff that has elected to return to the office will return in early 2022.

​

To support our customers or to comply with law, starting in 2020, we deferred loan payments from 90 to 360 days for consumer and commercial customers. We will continue to offer COVID-19 deferrals through September 30, 2022. For customers directly impacted by the COVID-19 pandemic, we suspended residential property foreclosure sales and involuntary automobile repossessions through October 1, 2020, which was the latest moratorium expiration for states in our footprint. Eviction actions were suspended through December 31, 2020 per Centers for Disease Control and Prevention Agency Order 2020-19654. Additionally, we offered fee waivers, payment deferrals, and other expanded assistance for automobile, mortgage, small business and personal lending customers.

​

Also, we have extended credit to both customers and non-customers related to the Paycheck Protection Program (“PPP”) loans. As of December 31, 2021, we have produced approximately 28,000 loans totaling approximately $3.2 billion through the PPP. Approximately $244.6 million of those PPP loans remain outstanding as of December 31, 2021.

​

The CFPB issued guidelines applicable to mortgage borrowers impacted by COVID-19 relating to loss mitigation and loan modifications which remain in effect from August 26, 2021 until September 30, 2022. We have confirmed that the Company’s current mortgage loan standards and processes meet all of the guidelines set forth by the CFPB. Future governmental actions may require more of these and other types of customer-related responses.

​

As of December 31, 2021, we have deferrals of $8.5 million, or 0.04%, of our total loan portfolio, excluding loans held for sale and PPP loans. For commercial loans, the standard deferral was 90 days for both principal and interest, 120 days of principal only payments or 180 days of interest only payments. We have actively reached out to our customers to provide guidance and direction on these deferrals. In terms of available lines of credit, the Company has not experienced an increase in borrowers drawing down on their lines.

​

While deferrals have been decreasing materially since the third quarter of 2020, given the fluidity of the pandemic and the risk there may be new lockdowns or restrictions on business activities to slow the spread of the virus, there is no guarantee that some loans not currently on deferral might return to deferral status.

​

A restructuring that results in only a delay in payments that is insignificant is not considered an economic concession. In accordance with the CARES Act, the Company implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. The Company’s payment relief assistance includes forbearance, deferrals, extension and re-aging programs, along with certain other modification strategies. The Company elected the accounting policy in the CARES Act to suspend TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic if the concession met the criteria defined under the CARES Act.

​

We are continuously monitoring the impact of the COVID-19 pandemic on our results of operations and financial condition. With the adoption of ASU 2016-13 on January 1, 2020, the Company changed its method for calculating its ACL for loans, investments, unfunded commitments and other financial assets. As a result of the new accounting standard, the Company changed its method for calculating its ACL for loans from an incurred loss method to a life of loan method. Considering the COVID-19 pandemic in our CECL models and moving to one CECL model (with the merged bank) during the third quarter of 2020, we recorded a provision for credit losses of $236.0 million in 2020. The recorded amount mainly was from the second quarter 2020, where the provision for credit losses was comprised of three major components: (1) $119.1 million for the day 1 provision for loans without significant credit deterioration (“Non-PCD”) acquired from CSFL, (2) $31.3 million from the legacy SouthState loan portfolio, and (3) $1.1 million from the acquired CSFL loan portfolio since the merger date. While there have been improvements in the economic forecasts during 2021, resulting in a recovery for credit losses of $165.3 million during the current year, there is continued uncertainty around the COVID-19 pandemic and its latest Omicron variant that may result in additional provision for credit losses in the future.

​

We also are monitoring the impact of COVID-19 on the valuation of goodwill. Additional detail in regards to

Atlantic Capital Bancshares, Inc. Merger

On July 23, 2021, SouthState and Atlantic Capital announced that the two companies had entered into a Merger Agreement, which provides that upon the terms and subject to the conditions set forth in the Merger Agreement, Atlantic Capital will merge with and into SouthState, with SouthState continuing as the surviving corporation in the merger. The Merger Agreement was unanimously approved by the Board of Directors of the Company and Atlantic Capital’s shareholders. The Company received OCC’s approval for the pending merger in October 2021, and the Federal Reserve Board’s approval in February 2022.

​

Under the terms of the Merger Agreement, shareholders of Atlantic Capital will receive 0.36 shares of SouthState’s common stock for each share of Atlantic Capital common stock they own. The transaction is expected to close during the first quarter of 2022. At December 31, 2021, Atlantic Capital reported $3.8 billion in total assets, $2.4 billion in loans and $3.3 billion in deposits.

​

CenterState Bank Corporation Merger

​

On June 7, 2020, the Company acquired all of the outstanding common stock of CSFL, the holding company for CSB, in a stock transaction. Pursuant to the merger agreement, (i) CSFL merged with and into the Company, with the Company continuing as the surviving corporation in the Merger, and (ii) immediately following the Merger, SSB merged with and into CSB, with CSB continuing as the surviving bank in the Bank Merger. In connection with the Bank Merger, CSB changed its name to SouthState Bank, National Association. CSFL common shareholders received 0.3001 shares of the Company’s common stock in exchange for each share of CSFL stock resulting in the Company issuing 37,271,069 shares of its common stock. In total, the purchase price for CSFL was $2.3 billion including the value of the conversion of outstanding warrants, stock options and restricted stock units totaling $10.3 million.

​

In the acquisition, the Company acquired $13.0 billion of loans (excluding loans held for sale) at fair value, net of $239.5 million, or 1.82%, estimated discount to the outstanding principal balance. Of the total loans acquired, Management identified $3.1 billion with credit deficiencies that were identified as Purchased Credit Deteriorated (“PCD”) loans. The Company assumed $15.6 billion in deposits including a $20.2 million premium for fixed maturity time deposits.

​

As a result of the Bank Merger, the Bank became a national banking association that is subject to primary

supervision and regulation by the OCC and subject to the National Bank Act, and is no longer subject to supervision and regulation by the SCBFI. In addition, the FDIC is no longer the Bank’s primary federal regulator, and the Bank is now a member of the Federal Reserve System.

​

Branch Consolidation and Other Cost Initiatives

​

As a part of the ongoing evaluation of customer service delivery and efficiencies, the Company consolidated branch locations in the first quarter of 2021. The annual savings in 2022 of these closures, which primarily includes personnel, facilities, and equipment cost, is expected to be $726,000, and the impact in 2021 was approximately $605,000. Two of the locations were in Florida and two in Georgia.

​

Capital Management

​

On January 27, 2021, the Board of Directors of the Company approved the authorization of a 3.5 million share Company stock repurchase plan (the “2021 Stock Repurchase Plan”). During 2021, the Company repurchased a total of 1,817,941 shares for $146.4 million or $80.51 per share (excluding commission expense).

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared based on the application of accounting policies in accordance with generally accepted accounting principles (“GAAP”) and follow general practices within the banking industry. Our financial position and results of operations are affected by Management’s application of accounting

54

Table of Contents

policies, including estimates, assumptions and judgments made to arrive at the carrying value of assets and liabilities and amounts reported for revenues and expenses. Differences in the application of these policies could result in material changes in our consolidated financial position and consolidated results of operations and related disclosures. Understanding our accounting policies is fundamental to understanding our consolidated financial position and consolidated results of operations. Accordingly, our significant accounting policies and changes in accounting principles and effects of new accounting pronouncements are discussed in Note 1 of our audited consolidated financial statements.

The following is a summary of our critical accounting policies that are highly dependent on estimates, assumptions and judgments.

Business Combinations

​

We account for acquisitions under FASB ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, and liabilities assumed, are recorded at fair value. We adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020 which now requires us to record purchased financial assets with credit deterioration (PCD assets), defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no provision for credit losses affecting net income on acquisition of PCD assets. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit loss expense (or recovery of credit losses) in subsequent periods as they arise. Any non-credit discount or premium resulting from acquiring a pool of purchased financial assets with credit deterioration shall be allocated to each individual asset. At the acquisition date, the initial allowance for credit losses determined on a collective basis shall be allocated to individual assets to appropriately allocate any non-credit discount or premium. The non-credit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted into interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date.

​

A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and non-credit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted into interest income using the effective yield method.

​

For further discussion of our loan accounting and acquisitions, see Note 1—Summary of Significant Accounting Policies, Note 2—Mergers and Acquisitions, Note 4—Loans and Note 5—Allowance for Credit Losses to the audited condensed consolidated financial statements.

​

Allowance for Credit Losses or ACL

​

The ACL reflects Management’s estimate of expected credit losses that will result from the inability of our borrowers to make required loan payments. Due to the Merger between the Company and CSFL, effective June 7, 2020, Management collectively evaluated loans utilizing two different methodologies for the second quarter 2020. Subsequently during the third quarter 2020, Management adopted one methodology. Management used the one systematic methodology to determine its ACL for loans held for investment and certain off-balance-sheet credit exposures. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may result in a range of expected credit losses. It is possible that others, given the same information, may at any point in time reach a different reasonable conclusion. The Company’s ACL recorded in the balance sheet reflects Management’s best estimate within the range of expected credit losses. The Company recognizes in net income the amount needed to adjust the ACL for Management’s current estimate of expected credit losses. See Note 1—Summary of Significant Accounting Policies for further detailed descriptions of our estimation process and methodology related to the ACL. See also Note 5—Allowance for Credit Losses and “Provision for Credit Losses” in this MD&A.

Other Real Estate Owned and Bank Property Held For Sale

​

Other real estate owned (“OREO”) consists of properties obtained through foreclosure or through a deed in lieu of foreclosure in satisfaction of loans. Prior to the merger with CSFL, we classified former branch sites as OREO. During the second quarter of 2020 and with the merger with CSFL, the Company elected to reclassify these assets as bank property held for sale and report on a separate line within the Consolidated Balance Sheet. Both OREO and bank property held for sale are recorded at the lower of cost or fair value and the fair value was determined on the basis of current valuations obtained principally from independent sources, adjusted for estimated selling costs. At the time of foreclosure or initial possession of collateral, for OREO, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the ACL. At the time a bank property is no longer in service and is moved to held for sale, any excess of the current book value over fair value is recorded as Noninterest Expense in the Consolidated Statements of Income. Subsequent adjustments to this value are described below in the following paragraph.

​

We report subsequent declines in the fair value of OREO and bank properties held for sale below the new cost basis through valuation adjustments. Significant judgment and complex estimates are required in estimating the fair value of these properties, and the period of time within which such estimates can be considered current is significantly shortened during periods of market volatility. In response to market conditions and other economic factors, Management may utilize liquidation sales as part of its problem asset disposition strategy. As a result of the significant judgments required in estimating fair value and the variables involved in different methods of disposition, the net proceeds realized from sales transactions could differ significantly from the current valuations used to determine the fair value of these properties. Management reviews the value of these properties periodically and adjusts the values as appropriate. Revenue and expenses from OREO operations, as well as gains or losses on sales and any subsequent adjustments to the value are recorded as OREO Expense in the Consolidated Statements of Income. Gains or losses on sale of bank properties held for sale, and generally any subsequent write-downs to the value, are recorded as a component in Other Expense in the Consolidated Statements of Income.

Goodwill and Other Intangible Assets

​

Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed in a business combination. As of December 31, 2021 and 2020, the balance of goodwill was $1.6 billion. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value.

​

In January 2017, the FASB issued ASU No. 2017-04, which simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on Step 1 of the previous accounting guidance’s two-step impairment test under ASC Topic 350. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The new standard eliminates the requirement to calculate a goodwill impairment charge using Step 2 which involved calculating an implied fair value of goodwill for each reporting unit for which the first step indicated impairment. The standard does not change the guidance on completing Step 1 of the goodwill impairment test. An entity will still be able to perform today’s optional qualitative goodwill impairment assessment before proceeding to the quantitative step of determining whether the reporting unit’s carrying amount exceeds it fair value. This guidance was effective for the Company as of January 1, 2020.

​

During the second quarter of 2021, the Company changed its annual goodwill valuation date to October 31 each year in order for the valuation to be closer to our year-end audit date. We evaluated the carrying value of goodwill as of October 31, 2021, our annual test date, considering the effects of COVID-19, and determined that no impairment charge was necessary. Our stock price has historically traded above its book value. However, during the first quarter of 2020, our stock price fell below book value and remained below book value until November 2020. This drop in stock price was mainly in reaction to the COVID-19 pandemic, which effected stock prices of companies in almost all industries. The lowest trading price for our stock during 2021 was $62.60, which was below year-end book value of $69.27. On December 31, 2021, our stock price closed at $80.11, which is above the book value of $69.27 and tangible book value of $44.62. Based upon our internal valuation and analysis as of October 31, 2021, we determined that no impairment charge was necessary at this time. We will continue to monitor the impact of COVID-19 on the Company’s business,

56

Table of Contents

operating results, cash flows and financial condition. If the COVID-19 pandemic continues and the economy continues to deteriorate and our stock price falls below current levels, we will have to reevaluate the impact on our financial condition and potential impairment of goodwill.

​

Core deposit intangibles and client list intangibles consist primarily of amortizing assets established during the acquisition of other banks. This includes whole bank acquisitions and the acquisition of certain assets and liabilities from other financial institutions. Core deposit intangibles represent the estimated value of long-term deposit relationships acquired in these transactions. Client list intangibles represent the value of long-term client relationships for the correspondent banking and wealth and trust management business. These costs are amortized over the estimated useful lives, such as deposit accounts in the case of core deposit intangible, on a method that we believe reasonably approximates the anticipated benefit stream from this intangible. The estimated useful lives are periodically reviewed for reasonableness.

Income Taxes and Deferred Tax Assets

​

Income taxes are provided for the tax effects of the transactions reported in our consolidated financial statements and consist of taxes currently due plus deferred taxes related to differences between the tax basis and accounting basis of certain assets and liabilities, including loans, available for sale securities, ACL, write downs of OREO properties and bank properties held for sale, accumulated depreciation, net operating loss carry forwards, accretion income, deferred compensation, intangible assets, mortgage servicing rights, and post-retirement benefits. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. A valuation allowance is recorded in situations where it is “more likely than not” that a deferred tax asset is not realizable. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The Company and its subsidiaries file a consolidated federal income tax return. Additionally, income tax returns are filed by the Company or its subsidiaries in the states of Alabama, California, Colorado, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Texas, New York and Virginia and city of New York City. We evaluate the need for income tax reserves related to uncertain income tax positions but had no material reserves at December 31, 2021 or 2020.

Recent Accounting Standards and Pronouncements

For information relating to recent accounting standards and pronouncements, see Note 1 to our audited consolidated financial statements entitled “Summary of Significant Accounting Policies.”

Results of Operations

Consolidated net income available to common shareholders increased by $354.9 million for the year ended December 31, 2021 compared to the year ended December 31, 2020. This increase reflects a decrease in provision for credit losses, an increase in interest income, a decrease in interest expense, and an increase in noninterest income. Partially offsetting these positive effects on net income was an increase in noninterest expense and an increase in the provision for income taxes. The increase in net income was due to the effects from the merger with CSFL in 2020 with the Company having a full year of net interest income and noninterest income from the merger in 2021 along with the Company having a lower amount of merger related expenses in 2021. Another significant impact was related to the releases in the allowance for credit losses in 2021 compared to provision for credit losses in 2020.

Below are key highlights of our results of operations during 2021:

| ● | Consolidated net income available to common shareholders increased 294.2% to $475.5 million in 2021 compared to $120.6 million in 2020, and increased $289.1 million, or 155.0%, from $186.5 million compared to 2019.

| o | Decreased provision for credit losses of $401.3 million as the Company recorded a release of the allowance for credit losses of $165.3 million in 2021 while in 2020, the Company recorded the provision for credit losses of $236.0 million which included an initial Day 1 provision of $119.0 million on Non-PCD loans and unfunded commitments acquired from CSFL (i.e., the impact of the adoption of CECL on Non-PCD acquired loans) and $117.0 million in provision for credit losses on loans. This provision for credit losses

57

Table of Contents

|  | was the result of forecasted losses that took into consideration the impact of the COVID-19 pandemic on the overall economic environment and the potential impact on the overall loan portfolio. During 2021, with the continued stabilization in the economy, the Company released some of the allowance for credit losses based on improvements in economic forecasts;

| o | Increased interest income of $174.8 million, resulting from a $139.3 million increase in interest income from loans and loans held for sale, a $32.9 million increase in interest income from investment securities, and a $2.6 million increase in interest income on federal funds sold, securities purchased under agreement to resell and interest-bearing deposits.

| ◾ | The increase in interest income on loans resulted from a higher non-acquired loan interest income of $115.1 million due to an increase in average balances through organic loan growth and the renewal of acquired loans that are moved to our non-acquired loan portfolio. The increase in interest income due higher average balance was partially offset by a 12 basis point decline in the yield.

| ◾ | Interest income on acquired loans increased $25.7 million due to a higher average balance from the loans acquired in the merger with CSFL in June 2020, with 2021 having a full year’s effect of the acquired loans. This was partially offset by a 41 basis point decline in the yield on the acquired loan portfolio.

| ◾ | The increase in interest income from investment securities was due to an increase in the average balance in 2021 as the Company strategically invested its excess funds from continued deposit growth, which was partially offset by a decline in the yield of 36 basis points resulting from the ongoing lower interest rate environment;

| o | Decreased interest expense of $31.9 million due to a 27 basis point decrease in the cost of total interest-bearing liabilities. The decrease in cost of interest-bearing liabilities was due to the continued low interest rate environment along with the reduction in the average balance of higher costing corporate and subordinated debentures and other borrowings.

| o | Increased noninterest income of $43.1 million was primarily from a $45.3 million increase in correspondent banking and capital markets income, a $21.3 million increase in fees on deposit accounts, a $7.5 million increase in trust and investment services income, and a $7.0 million increase in Bank Owned Life Insurance (“BOLI”) income. These increases were partially offset by a $41.6 million decline in mortgage banking income (See Noninterest Income section on page 63 for further discussion);

| o | Increased noninterest expense of $150.8 million was primarily from a $135.4 million increase in salaries and employee benefits expense, a $16.6 million increase in occupancy expense, a $14.6 million increase in information services expense. In addition, with the redemption of the $38.5 million trust preferred securities, the remaining fair value mark of $11.7 million was written off as an extinguishment of debt cost during the second quarter of 2021. These increases were partially offset by a $38.8 million swap termination expense that occurred in the fourth quarter of 2020 along with an $18.7 million decrease in merger and branch consolidation related expense. (See Noninterest Expense section on page 65 for further discussion); and

| o | Higher income tax provision of $145.4 million due to higher pretax book income in 2021 compared to 2020 along with the recognition of a one-time benefit of $31.5 million recorded in the fourth quarter 2020 related to the ability to carryback tax losses under the CARES Act. The Company recorded pretax book income of $604.3 million in 2021 compared to pretax income of $104.0 million in 2020.

| ● | Basic earnings per common share increased 207.3% to $6.76 in 2021, from $2.20 in 2020 and increased 25.2% from $5.40 in 2019.

| ● | Diluted earnings per common share increased 206.4% to $6.71 in 2021, from $2.19 in 2020, and increased 25.2% from $5.36 in 2019.

| ● | Return on average assets was 1.19% in 2021, compared to 0.42% in 2020 and to 1.21% in 2019. The increase in 2021 compared to 2020 was driven by the growth in net income of 294.2%, or $354.9 million, to $475.5 million being greater than the increase in total average assets of 39.1%, or $11.3 billion, to $40.0 billion in 2021. As mentioned previously, the growth in net income as well as the increase in average assets was mainly related to the full year impact from the merger with CSFL in the second quarter of 2020. The increase in net income was also due to the reversals of provision for credit losses in 2021 as economic forecasts improved

|  | related to the COVID-19 pandemic. The decrease in 2020 compared to 2019 was driven by the increase in total average assets of 86.4%, or $13.3 billion, to $28.8 billion in 2020 due to the merger with CSFL, as well as a decline in net income of 35.3%, or $65.9 million, to $120.6 million in 2020.

| ● | Return on average common shareholders’ equity increased to 10.01% in 2021, compared to 3.35% in 2020, and 7.89% in 2019. The increase in 2021 compared to 2020 was driven by the greater growth in net income of 294.2%, or $354.9 million, to $475.5 million compared to an increase in average common shareholders’ equity of 31.72%, or $1.1 billion, in 2021. As mentioned above, the increase in net income was mainly due to a full year’s impact from the merger with CSFL along with the reversals of provision for credit losses in 2021 related to improved economic forecasts related to the COVID-19 pandemic. The decrease in 2020 compared to 2019, was driven by both an increase in average common shareholders’ equity of 52.5%, or $1.2 billion, and a decline in net income of 35.3%, or $65.9 million, in 2020. The increase in average equity was due to the equity issued in the merger with CSFL in the second quarter of 2020 and the decline in net income was mainly due to the Day 1 provision for credit losses and expenses related to the merger with CSFL.

| ● | Our dividend payout ratio was 28.43% for 2021 compared with 81.45% in 2020 and 30.94% in 2019. The decrease in the dividend payout ratio in 2021 compared to 2020 was due to the growth in net income available to common shareholders, which increased 294.2%, being greater than the increase in dividends paid of 37.7%, or $37.1 million. The increase in net income in 2021 was mainly due to lower net income in 2020 attributable to the Day 1 provision for credit losses from the CSFL merger, higher provision for credit losses due the COVID-19 pandemic and expenses related to the merger with CSFL. The increase in the dividends paid was due to the increase in average outstanding shares from the merger with CSFL for a full year in addition to the Company increasing the cash dividend per share from $0.47 to $0.49 starting in the third quarter of 2021. The increase in the dividend payout ratio in 2020 compared to 2019, was due to the increase in dividends paid of 70.3%, or $40.6 million as well as the decline in net income available to common shareholders, which decreased 35.3%. The increase in the dividends paid was due the increase in outstanding shares from the merger with CSFL and the decline in net income was mainly due to the Day 1 provision for credit losses and expenses related to the merger with CSFL.

Net Interest Income

Net interest income is the largest component of our net income. Net interest income is the difference between income earned on interest-earning assets and interest paid on deposits and borrowings. Net interest income is determined by the yields earned on interest-earning assets, rates paid on interest-bearing liabilities, the relative balances of interest-earning assets and interest-bearing liabilities, the degree of mismatch, and the maturity and repricing characteristics of interest-earning assets and interest-bearing liabilities. Net interest income divided by average interest-earning assets represents our net interest margin.

During 2019, the Federal Reserve’s Federal Open Market Committee’s target for federal funds target rate remained at the 2.25% to 2.50% range until July 2019 when the Federal Reserve began to drop the federal funds target rate. In the last half of 2019, the Federal Reserve dropped the federal funds target rate 75 basis points to the range of 1.50% to 1.75% at December 31, 2019. The Federal Reserve then dropped the federal funds target rate 150 basis points to a range of 0.00% to 0.25% in March 2020 in reaction to the COVID-19 pandemic. This drop in interest rates in 2019 and 2020 continued to affect both our net interest income and net interest margin for the year ended 2021. The yield on interest-earning assets declined 54 basis points in 2021 compared to 2020 and by 83 basis points in 2020 compared to 2019. The yield on our acquired loan portfolio decreased 41 basis points in 2021 from 2020 after a decrease of 147 basis point in 2020 from 2019 and the yield on our non-acquired loan portfolio decreased of 12 basis points in 2021 from 2020 after a decrease of 38 basis points in 2020 from 2019. These declines in yields on earning assets were the main drivers in the net interest margin declining 36 basis points in 2021 compared to 2020 and 51 basis points in 2020 compared to 2019.

We have also continued focusing on increasing core deposits (excluding certificates of deposits and other time deposits). The core deposits grew primarily due to the federal government pushing funds into the market through stimulus programs, in addition to consumers remaining conservative in their spending habits in reaction to the COVID-19 pandemic. These funds are normally lower cost funds. As a result, the cost of interest-bearing deposits decreased 21 basis points in 2021 after decreasing 40 basis points in 2020. The overall cost on all interest-bearing liabilities declined in 2021 compared to 2020 by 27 basis points. The decrease in the cost of interest-bearing liabilities has had a positive effect on our net interest income and net interest margin for 2021, however, the negative effect on the yield on interest earning assets has been greater.

2021 compared to 2020

Net interest income and net interest margin highlighted for the year ended December 31, 2021, compared to 2020:

| ● | Our net interest income increased by $206.8 million, or 25.0%, to $1.0 billion during 2021, compared to 2020, as interest income increased $174.8 million and interest expense declined $31.9 million.

| o | Our interest income increased by $174.8 million due to -

| ◾ | Higher non-acquired loan interest income of $115.1 million due to a higher average balance of $3.4 billion, higher investment securities interest income of $32.9 million because of higher average balances of $2.9 billion, acquired loan interest income increasing by $25.7 million because of higher average balances in acquired loans of $1.4 billion, and higher federal funds sold and repurchase agreements interest income of $2.6 million because of higher average balances of $2.8 billion.

| ◾ | These increases in interest income were partially offset by lower interest income of $1.5 million on loans held for sale due to lower average balances of $54.3 million.

| ◾ | The effects from the increases in the average balance of interest-earning assets have outweighed the effects of the declines in average yields in 2021.

| o | Average interest-earning assets increased $10.3 billion, or 40.6%, to $35.8 billion in 2021, compared to 2020. The increase in the average balance on the non-acquired loan portfolio of $3.4 billion was due to organic growth and renewals of acquired loans that are moved to our non-acquired loan portfolio. The increase in the average balance on the acquired loan portfolio of $1.4 billion was due to the loans acquired from the merger with CSFL being only outstanding 207 days in 2020. Although the acquired loan portfolio increased from 2020, it has declined throughout 2021 due to paydowns, pay-offs and renewals of acquired loans that are moved to our non-acquired loan portfolio. The increase in the average balance in investment securities of $2.9 billion was a result of the Company’s decision to strategically increase the investment portfolio due to the excess liquidity from deposit growth.

| o | Overall, our yield on interest-earning assets in 2021 declined 54 basis points from 2020, due to the falling interest rate environment resulting from the drops in the federal funds rate made by the Federal Reserve in March 2020. The yield on the non-acquired loan portfolio decreased 12 basis points, the acquired loan portfolio yield declined 41 basis points, the yield on investment securities dropped by 36 basis points, and on the yield on federal funds sold, securities purchased under agreements to resell and interest-bearing deposits decreased by 3 basis points. The yield on loans held for sale remained flat. The yield on interest-earning assets also declined as the average balance of lower yielding federal funds sold, securities purchased under agreements to resell, interest-bearing deposits and investment securities increased as a percentage of total interest-earning assets from 22.8% to 31.9%.

| o | Our interest expense declined by of $31.9 million in 2021 compared to 2020 due to –

| ◾ | Interest expense on interest-bearing deposits declining $22.3 million because of a reduction in the average cost of 21 basis points, interest expense related to other borrowings declined $8.9 million because of a lower average balance of $662.6 million, and the interest expense on repurchase agreements declined $790,000 because of a decrease in the average cost of 27 basis points.

| ◾ | The effects from the declines in average cost of interest-bearing liabilities have outweighed the effects of the increases in average balance in 2021.

| o | Average interest-bearing liabilities increased $6.2 billion, or 36.1%, to $23.2 billion in 2021 compared to 2020 mainly due the acquired interest-bearing liabilities from the merger with CSFL only outstanding for 207 days in 2020. The average balance of interest-bearing deposits increased $6.5 billion, the average balance of federal funds purchased increased $259.7 million and repurchase agreements increased $65.1 million. The average balance on other borrowing decreased $662.6 million. Within other borrowings, the average balance on corporate and subordinated debentures increased $81.4 million as the Company assumed $271.5 million in borrowings in the merger with CSFL. The increase related to the merger was partially offset by the Company’s redemption of $63.5 million of subordinated debentures and trust preferred securities assumed from the CSFL merger in June 2021. The average balance of FHLB and FRB borrowings decreased $744.0 million due to the Company’s strategic decision to payoff $700.0 million of

|  | FHLB advances (along with the termination of interest rate hedges on these borrowings) in the fourth quarter of 2020.

| o | The average cost of interest-bearing liabilities in 2021 compared to 2020 decreased 27 basis points. This decrease occurred in all categories of funding, except for other borrowings which increased 229 basis points in 2021. The primary cause for the lower cost on interest-bearing deposits of 21 basis points, federal funds purchased of 8 basis points and repurchase agreements of 27 basis points was the continued low interest rate environment. The cause for the increase in cost on other borrowings in 2021 is due to having a full year’s impact from the higher cost subordinated debt assumed in the CSFL merger along with the effects of paying off the lower cost FHLB and FRB borrowings (along with the termination of the interest rate hedges on these borrowing) in the fourth quarter of 2020.

| ● | Both the non-tax equivalent and the tax equivalent net interest margin decreased by 36 basis points in 2021 compared to 2020 due to the decline in the yield on interest earning assets of 54 basis points, which was only partially offset by a decrease in cost of interest-bearing liabilities of 27 basis points.

2020 compared to 2019

Net interest income and net interest margin highlighted for the year ended December 31, 2020, compared to 2019:

| ● | Our net interest income increased by $322.2 million, or 63.9%, to $826.5 million during 2020, compared to 2019, as interest income increased $319.2 million and interest expense declined $3.0 million.

| ● | Our interest income increased by $319.2 million with acquired loan interest income increasing by $258.8 million because of higher average balances of acquired loans of $6.1 billion, higher non-acquired loan interest income of $51.0 million due to a higher average balance of $2.1 billion, higher investment securities interest income of $8.5 million because of higher average balances of $1.2 billion and higher interest income of $6.6 million on loans held for sale due to higher average balances of $250.4 million. These increases in interest income were partially offset by a $5.7 million decline in federal funds sold and repurchase agreements interest income as the yield declined by 191 basis points, offsetting the effects of the average balance increasing by $2.4 billion. The effects from the increases in average balance of interest-earning assets have outweighed the effects of the declines in average yields in 2020.

| ● | Average interest-earning assets increased $12.0 billion, or 89.8%, to $25.5 billion in 2020, compared to 2019 mainly due to the merger with CSFL. The average balance of our acquired loans portfolio increased by $6.1 billion as the Company acquired $13.0 billion in loans from the merger with CSFL in June 2020. The average balance of our non-acquired loan portfolio increased $2.1 billion because of organic growth. In addition, the average balance of federal funds sold, securities purchased under agreements to resell and interest-bearing deposits increased $2.4 billion and the average balance of investment securities increased $1.2 billion, as we acquired $2.6 billion in cash and cash equivalents and $1.2 billion in investment securities in the merger with CSFL. The increase in the average balance of loans held for sale was due to both the increase in volume from the merger with CSFL along with additional mortgage volume resulting from the decrease in interest rates in 2020.

| ● | Overall, our yield on interest-earning assets in 2020 decreased 83 basis points from 2019, due to a falling interest rate environment as the Federal Reserve dropped the federal funds target rate by 75 basis points from July 2019 to October 2019 and then dropped the federal funds target rate 150 basis points to a range of 0.00% to 0.25% in March 2020 in response to the COVID-19 pandemic. The yield on the non-acquired loan portfolio declined 38 basis points, on the acquired loan portfolio of 147 basis points, on the investment securities by 81 basis points, on federal funds sold, securities purchased under agreements to resell and interest-bearing deposits of 191 basis points and loans held for sale by 97 basis points.

| ● | Our interest expense decreased by $3.0 million in 2020 compared to 2019 with interest expense on interest-bearing deposits declining $10.5 million because of a lower average cost of 40 basis points and with interest expense on federal funds purchased and repurchase agreements declining $677,000 because of a lower average cost of 58 basis points. These declines in interest expense were partially offset by an increase interest expense from borrowings of $8.2 million because of a higher average balance of $362.7 million, mainly due to the assumption of borrowings from the merger with CSFL. The effects from the declines in average cost of interest-bearing liabilities have outweighed the effects of the increases in average balance in 2020.

Table of Contents

| ● | Average interest-bearing liabilities increased $7.5 billion, or 77.9%, to $17.1 billion in 2020 compared to 2019 mainly due to the merger with CSFL. The average balance of interest-bearing deposits increased $6.8 billion as the Company acquired $10.3 billion in interest-bearing deposits from the merger with CSFL in June 2020. The average balance of federal funds purchased and repurchase agreements increased $270.9 million as the Company acquired $401.5 million in federal funds purchased and repurchase agreement from the merger with CSFL. The average balance of borrowings increased $362.7 million as the Company assumed $271.5 million in borrowings from the merger with CSFL along with the average balance of FHLB Advances held during 2020 being higher by $175.8 million in 2020 compared to 2019.

| ● | The average cost of interest-bearing liabilities in 2020 compared to 2019 decreased 41 basis points. This decrease occurred in all categories of funding and was due to the falling interest rate environment in the last half of 2019 and in 2020. The average cost on interest bearing deposits declined 40 basis points, federal funds purchased and repurchase agreement declined 58 basis points and borrowing declined 18 basis points. The decline in the average cost of borrowing due to the decline in interest rates was partially offset by the higher average cost on the subordinated debentures assumed in the merger with CSFL in the second quarter of 2020 along with the rising costs of the cash flow hedges on $700 million of FHLB advances held during most of 2020. The $700 million in FHLB advances and the cash flow hedges tied to these advances were paid-off and terminated in the fourth quarter of 2020.

| ● | Both the non-tax equivalent and the tax equivalent net interest margin decreased by 51 basis points 2020 compared to 2019 due to the decline in the yield on interest earning assets of 83 basis points, which was only partially offset by the lower cost of interest-bearing liabilities of 41 basis points. Our interest-earning assets have repriced more quickly than our interest-bearing liabilities as rates have fallen in the last half of 2019 and in 2020 causing the net interest margin to decline.

Noninterest Income and Expense

Noninterest income provides us with additional revenues that are significant sources of income. In 2021, 2020, and 2019, noninterest income comprised 25.5%, 27.4%, and 22.2%, respectively, of total net interest income and noninterest income. Note that recoveries on acquired loans were no longer recorded through the income statement beginning in 2020 with the adoption of CECL. These recoveries are now recorded through the allowance for credit losses on the balance sheet.

2021 compared to 2020

Our noninterest income increased 13.8% for the year ended December 31, 2021 compared to 2020. This change in total noninterest income resulted from the following:

| ● | Service charges on deposit accounts were higher in 2021 by $10.3 million, or 18.5%, compared to 2020, due primarily to the increase in customers and activity in 2021 through the merger with CSFL completed during the second quarter of 2020. Year-to-date 2020 only included CSFL activity from June 8, 2020 through December 31, 2020. The increase in service charges on deposit accounts was mainly driven by an increase in service charge maintenance fees on checking and savings accounts, in net non-sufficient funds and overdraft protection fee income, in fees related to wire transfers and in commissions from sales of checks.

| ● | Debit, prepaid, ATM and merchant card related income was higher by $11.0 million, or 38.5%, in 2021 compared to 2020. The increase in debit, prepaid, ATM and merchant card related income was mainly driven by higher debit card, credit card sales incentive, and ATM and merchant card income due to the increase in activity related to the merger with CSFL completed in the second quarter of 2020. Year-to-date 2020 only included CSFL activity from June 8, 2020 through December 31, 2020.

| ● | Mortgage banking income decreased by $41.6 million, or 39.2%, which was comprised of $42.2 million, or 41.2%, decrease from mortgage income in the secondary market, partially offset by a $578,000, or 15.5%, increase from mortgage servicing related income, net of the hedge. During 2021, mortgage income from the secondary market comprised of a $8.9 million decline in the change in fair value of the pipeline, loans held for sale and MBS forward trades and a $33.3 million decrease in the net gain on sale of mortgage loans. Net gains on the sale of mortgage loans was $75.1 million in 2021, which is net of the commission expense related to mortgage production of $27.2 million. During the second quarter of 2021, the Company began allocating a lower percentage of its mortgage production and pipeline to the secondary market compared to 2020, which resulted in lower mortgage income from the secondary market. This change was mainly due to the increase in liquidity held at the Bank along with the reduction in the gain on sale margin in 2021 compared to 2020. The allocation of mortgage production between portfolio and secondary market depends on the Company’s liquidity, market spreads and rate changes during each period and will fluctuate quarter to quarter. The increase in mortgage servicing related income, net of the hedge during 2021 was due to a $4.4 million increase from servicing fee income, which was partially offset by a $3.8 million decrease in the change in fair value of the MSR including decay. The decrease in fair value of the MSR is due to an increase in MSR decay of $6.1 million and losses on the MSR hedge of $15.1 million, partially offset by an increase in the change in fair value from interest rates of $17.4 million compared to the 2020. The increase in the servicing fee income is due to the increase in size of the servicing portfolio during 2021.

| ● | Trust and investment services income increased $7.5 million, or 25.6%, in 2021 compared to 2020. The increase in business through the merger with CSFL which was completed in the second quarter of 2020 resulted in the increase in income. Also, assets under management have increased $902.0 million or 17.4% from December 31, 2020 to December 31, 2021.

| ● | Correspondent banking and capital markets income for 2021 increased by $45.3 million from 2020. Year-to-date 2020 only included CSFL correspondent banking activity from June 8, 2020 through December 31, 2020. Also, the acquisition of Duncan-Williams on February 1, 2021 contributed to the increase in correspondent banking and capital markets income during 2021. The income from this business includes commissions earned on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities.

| ● | Bank owned life insurance income increased $7.0 million, or 61.8%, in 2021 compared to 2020. This increase was due to an increase in the cash surrender value of $8.0 million which resulted from the $333.1 million of bank owned life insurance acquired in the merger with CSFL during the second quarter of 2020, along with the purchase of $205.6 million of policies in April 2021. This increase was partially offset by a $1.0 million decline in income resulting from the payout of insurance policies.

| ● | Other income increased by $3.5 million due to the merger with CSFL in the second quarter of 2020. This increase was mainly due to increases in SBA loan servicing fees and gains on sale of SBA loans of $6.1 million. The Company has also seen an increase in Small Business Investment Company (“SBIC”) investment income of $2.1 million during 2021 as the Company has increased its SBIC investment portfolio during 2020

|  | and 2021. These increases were partially offset by $3.6 million in income recorded in 2020 related to the credit valuation adjustment on the Company’s back-to-back interest rate swaps.

2020 compared to 2019

Our noninterest income increased 116.7% for the year ended December 31, 2020 compared to 2019 resulting primarily from the merger with CSFL in June of 2020. In addition, the following was also noted:

​

| ● | Service charges on deposit accounts and debit, prepaid, ATM and merchant card related income was higher in 2020 by $8.9 million than in 2019, due primarily to the increase in customers and activity through the merger with CSFL during the second quarter of 2020. Service charges on deposit accounts increased $3.7 million which was mainly attributable to an increase in service charge maintenance fees on checking accounts. Debit, prepaid, ATM and merchant card related income increased $5.1 million and was mainly attributable to an increase in debit card income.

| ● | Mortgage banking income increased by $88.6 million, or 504.7%, which was comprised of $85.2 million, or 491.8%, increase from mortgage income in the secondary market, and a $3.5 million, or 1389.3%, increase from mortgage servicing related income, net of the hedge. These increases were directly attributable to the increase in volume resulting from the low interest rate environment brought on by the pandemic and monetary policy of the US Government during 2020 along with the increase in volume due to the merger with CSFL. The increase in mortgage income from the secondary market in 2020 was due to a $93.1 million increase in the gain on sale of mortgage loans net of the cost related to mortgage production. This increase was offset by a $8.0 million decline in the change in fair value of the pipeline, loans held for sale and MBS forward trades. The increase in mortgage servicing related income, net of the hedge in 2020 was due to a $1.9 million increase in servicing fee income along with a $1.6 million increase in the change in fair value of the MSR including decay.

| ● | The merger with CSFL resulted in a significant increase in correspondent banking and capital markets income. The income for 2020 increased by $61.9 million, or 2138.7%. The income from this business includes commissions earned on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities.

| ● | Bank owned life insurance (“BOLI”) income is now reported separately (not included in Other Income) in the table above and increased by $5.6 million, or 97.6%, due to the merger with CSFL. Total BOLI increased to $559.4 million at December 31, 2020 as the Company acquired $333.1 million in BOLI through the merger with CSFL in 2020.

| ● | Recoveries on acquired loans declined by $6.8 million, given these are no longer recorded through the income statement, but through the balance sheet as a result of the adoption of CECL.

| ● | Securities gains, net, declined by $2.7 million compared to 2020. During 2019, securities gains were mainly a result of selling VISA Class B shares at a gain of $5.4 million partially offset by net realized losses of $2.7 million on lower yielding securities that were sold during the year.

| ● | Other income increased by $11.9 million primarily from income related to the merger with CSFL. Two of the largest categories were from the servicing and sale of SBA loans, which increased $5.7 million, and from an increase in rental income of $1.4 million.

Noninterest expense represents the largest expense category for our company. During 2021 and 2020, we continued to emphasize careful controls around our noninterest expense. With that, our expenses in 2021 increased $150.8 million or 18.9% from 2020, mainly due to the merger with CSFL. Noninterest expense increased $393.0 million or 97.1% in 2020 from 2019.

​

2021 compared to 2020

​

Noninterest expense increased $150.8 million, or 18.9% for the year ended December 31, 2021 compared to 2020. This increase was mainly due to 2021 having a full year’s effect from the merger with CSFL while 2020 was only partially affected from the merger date of June 7, 2020. The change in total noninterest expense resulted from the following:

​

| ● | Salary and employee benefits increased by $135.4 million, or 32.5%, as all categories of salaries and benefits expense increased due to the merger with CSFL. Salaries increased $66.9 million, benefits increased $11.4 million, commissions increased $32.5 million, and incentives increased $24.6 million. With the merger with CSFL in June 2020, the Company added approximately 2,800 employees, almost doubling its total employees.

| ● | In the fourth quarter of 2020, the company terminated three cash flow hedges (SWAPs) given the current low interest rate environment and expectation of low interest rates in the foreseeable future resulting in a termination cost of $38.8 million.

| ● | Merger and branch consolidation related expense decreased $18.7 million, or 21.7% in 2021 compared to 2020. Merger and branch consolidation expense of $64.4 million in 2021 and $83.0 million in 2020 was related primarily to the merger with CSFL.

| ● | The Company had extinguishment of debt cost of $11.7 million in 2021. This cost was from the write-off of the fair market value adjustment recorded on the trust preferred securities assumed in the CSFL merger. All of the trust preferred securities assumed in the CSFL merger were redeemed in June 2021.

| ● | Information services expense and occupancy expense increased $14.6 million, or 24.4% and $16.6 million, or 22.0%, respectively. These increases were related to the additional cost associated with facilities, employees and systems added through our merger with CSFL as our number of branches increased by 129 during 2020 to 285 at December 31, 2020. The number of branches declined slightly in 2021 to 281.

| ● | Amortization of intangibles increased $8.2 million, or 30.4%. This increase was due to the merger with CSFL, which resulted in the Company recording a core deposit intangible asset of $125.9 million and a correspondent banking customer intangible asset of $10.0 million in June of 2020.

| ● | FDIC assessment and other regulatory charges increased $7.3 million, or 67.9%. This increase was due to an increase in FDIC assessments and OCC examination fees resulting from the merger with CSFL and the growth since the merger, in addition to new regulatory charges attributable to Duncan-Williams.

Table of Contents

| ● | Business development and staff related expense increased $6.6 million, or 64.7% due mainly to the merger with CSFL with the increase in employees. The increase was also due to limited expense in 2020 attributable to the initial impact from the COVID-19 pandemic before vaccines were available.

| ● | Other noninterest expense increased by $8.0 million, or 18.6%. This increase was mainly due to a general increase in expenses due to the merger with CSFL including loan expenses, insurance expense, donations, various operational reserves, and operating charge-offs. There was also an increase of $2.8 million in cost associated with the Association Banking Prime Earnings Credit Program in 2021 from 2020.

​

2020 compared to 2019

​

Noninterest expense increased $393.0 million, or 97.1% for the year ended December 31, 2020 compared to 2019 resulting primarily the merger with CSFL in June 2020. Below includes additional discussion:

​

| ● | Salary and employee benefits increased by $181.9 million, or 77.5%, as all categories of salaries and benefits expense increased due to the merger with CSFL. With the merger, the number of full-time equivalent employees increased 103.5% from 2,547 at December 31, 2019 to 5,184 at December 31, 2020.

| ● | In the fourth quarter of 2020, the company terminated three cash flow hedges (SWAPs) given the current low interest rate environment and expectation of low interest rates in the foreseeable future resulting in a termination cost of $38.8 million.

| ● | Merger and branch consolidation related expense increased $81.4 million, or 1787.2%. This increase was related primarily to the merger with CSFL and includes cost both before and after the merger, including professional fees, severance, contract terminations, branch consolidations, fixed assets written off and other related cost. The costs in 2019 were mainly related to the consolidation of 13 branches during the year.

| ● | Information services expense increased $24.4 million, or 68.7%. This increase was related to the additional cost associated with facilities, employees and systems added through our merger with CSFL. Our number of branches increased by 129, or 83.2% from 155 at December 31, 2019 to 285 at December 31, 2020.

| ● | Occupancy expense increased $28.1 million, or 59.3%. This increase was related to the additional cost associated with facilities added resulting from our merger with CSFL. Our number of branches increased by 129, or 83.2% from 155 at December 31, 2019 to 285 at December 31, 2020.

| ● | Amortization of intangibles increased $13.9 million, or 106.3%. This increase was due to the merger with CSFL which resulted in the Company recording a core deposit intangible asset of $125.9 million and a correspondent banking customer intangible asset of $10.0 million in 2020.

| ● | FDIC assessment and other regulatory charges increased $6.2 million, or 135.7%. This increase was mainly due to the addition of assets and liabilities acquired through our merger with CSFL in the second quarter of 2020.

| ● | In 2019, the Company recorded a pension plan termination expense of $9.5 million related to the termination of our pension plan. This resulted in the recognition of the losses from the pension plan that were being held in accumulated other comprehensive income of $7.7 million and the write-off of the pension plan asset of $1.8 million.

| ● | Other noninterest expense increased by $20.6 million, or 93.2%. This increase was mainly due to a general increase in expenses due to the merger with CSFL including loan expenses, insurance expense, donations, various operational reserves, miscellaneous taxes and miscellaneous operating charge-offs. There was also a $6.5 million increase in passive losses recorded in 2020 related to tax credit partnerships. We added approximately $29 million more in these CRA investments in 2020, of which $13.8 million were acquired through the merger with CSFL. We added approximately $39 million of CRA investments in 2019.

​

Income Tax Expense

Our effective tax rate increased to 21.30% at December 31, 2021 compared to (16.02%) for the year-ended December 31, 2020. When excluding the tax loss carryback and other discrete items, the effective tax rate for the year-ended December 31, 2020 was 14.24%. The increase was mainly due to increased pre-tax book income, offset by an increase in tax-exempt income and federal tax credits available. For additional information refer to Note 12—income

Overview

​

At December 31, 2021, we had total assets of approximately $42.0 billion, consisting principally of $23.6 billion in net loans ($16.1 billion in non-acquired loans, $5.9 billion in acquired non-credit deteriorated loans, $2.0 billion in acquired credit deteriorated loans, net of $301.8 million allowance for credit losses), $7.2 billion in investment securities and $6.8 billion in cash and cash equivalents. Our liabilities at December 31, 2021 totaled $37.2 billion, consisting principally of deposits of $35.1 billion ($11.5 billion in noninterest-bearing and $23.6 billion in interest-bearing) and short-term and long-term borrowings of $1.1 billion. At December 31, 2021, our shareholders’ equity was $4.8 billion.

​

At December 31, 2020, we had total assets of approximately $37.8 billion, consisting principally of $24.2 billion in net loans ($12.3 billion in non-acquired loans, $9.5 billion in acquired non-credit impaired loans, $2.9 billion in acquired credit impaired loans, net of $457.3 million allowance for credit losses, $4.4 billion in investment securities and $4.6 billion in cash and cash equivalents. Our liabilities at December 31, 2020 totaled $33.1 billion, consisting principally of deposits of $30.7 billion ($9.7 billion in noninterest-bearing and $21.0 in interest-bearing) and short-term and long-term borrowings of $1.2 billion. At December 31, 2020, our shareholders’ equity was $4.6 billion.

Book value per common share was $69.27 at the end of 2021, an increase from $65.49 at the end of 2020. Book value per common share increased in 2021 as shareholder equity increased by 3.3% while common shares outstanding declined by 2.3%. The primary reason for an increase in shareholder’s equity of $155.0 million during 2021 was due to net income of $475.5 million. This increase was partially offset by declines in equity resulting from $135.2 million in dividends paid to shareholders, $146.4 million in common stock repurchased on the open market and $68.9 million reduction in AOCI related to unrealized losses on available for sale securities. The primary reason for the decline in common shares outstanding of 1.6 million was due to the Company repurchasing 1.8 million shares on the open market in 2021.

Our common equity to assets ratio decreased to 11.45% in 2021, compared with 12.30% in 2020. The decrease in 2021, compared to 2020, was the result of the percentage increase in total assets of 11.0% being greater than the percentage increase in shareholders’ equity of 3.3%. The increase in total assets was mainly due to the increase in cash and cash equivalents and investment securities as our liquidity has increased through the growth in deposits.

Trading Securities

We have a trading portfolio associated with our Correspondent Bank Division, that was inherited through the acquisitions of CSFL in June 2020 and Duncan Williams in February 2021. For this portfolio, realized and unrealized gains and losses are included in trading securities revenue, a component of Correspondent Banking and Capital Market Income in our “Consolidated Statements of Income”. Securities purchased for this portfolio have primarily been municipal, treasuries and mortgage-backed agency securities and are held for short periods of time and totaled $77.7 million and $10.7 million, respectively, at December 31, 2021 and 2020.

Investment Securities

We use investment securities, the second largest category of interest earning assets, to generate interest income through the employment of excess funds, to provide liquidity, to fund loan demand or deposit liquidation, and to pledge as collateral for public funds deposits, repurchase agreements and as collateral for derivative exposure. At December 31, 2021 and 2020, investment securities totaled $7.2 billion and $4.4 billion, respectively. For the year ended December 31, 2021, average investment securities were $5.7 billion, or 16.1% of average earning assets, compared with $2.9 billion, or 11.4% of average earning assets for the year ended December 31, 2020. The expected average life of the investment portfolio at December 31, 2021 was approximately 6.27 years, compared with 4.35 years at December 31, 2020. See Note 1—Summary of Significant Accounting Policies in the audited consolidated financial statements for our accounting policy on investment securities.

As securities are purchased, they are designated as held to maturity or available for sale based upon our intent, which considers liquidity needs, interest rate expectations, asset/liability management strategies, and capital requirements.

​

During 2021, our total investment securities increased $2.7 billion, or 61.3%, from December 31, 2020. During 2021, we purchased $3.9 billion of securities, $975.3 million classified as held to maturity and $2.9 billion classified as available for sale. We continue to increase our investment securities strategically primarily with excess funds due to deposit growth and excess liquidity. These purchases were partially offset by maturities, paydowns, sales and calls of investment securities totaling $1.1 billion. Net amortization of premiums were $38.0 million for the year ended December 31, 2021.

At December 31, 2021, the unrealized net loss of the available for sale investment securities portfolio was $27.8 million, or 0.5%, below its amortized cost basis. Comparable valuations at December 31, 2020 reflected an unrealized net gain of the available for sale investment portfolio of $62.6 million, or 1.9%, above its amortized cost basis. The decrease in fair value in the available for sale investment portfolio at December 31, 2021 compared to December 31, 2020 was mainly due to the increase in short and long term interest rates during 2021. At December 31, 2021, the unrealized net loss of the held to maturity investment securities portfolio was $41.8 million, or 2.3%, below its amortized cost basis. At December 31, 2020, the unrealized net gain of the held to maturity investment securities portfolio was $1.6 million, or 0.2%, above its amortized cost basis.

| * | Agency mortgage-backed securities (“MBS”), agency collateralized mortgage-obligations (CMO) and agency commercial mortgage-backed securities (“CMBS”) are guaranteed by the issuing government-sponsored enterprise (“GSE”) as to the timely payments of principal and interest. Except for Government National Mortgage Association securities, which have the full faith and credit backing of the United States Government, the GSE alone is responsible for making payments on this guaranty. While the rating agencies have not rated any of the MBS, CMO and CMBS issued, senior debt securities issued by GSEs are rated consistently as “Triple-A.” Most market participants consider agency MBS, CMOs and CMBSs as carrying an implied Aaa rating (S&P rating of AA+) because of the guarantees of timely payments and selection criteria of mortgages backing the securities. We do not own any private label mortgage-backed securities. The balances presented under the ratings above reflect the amortized cost of the investment securities.

Held to maturity

As described above the Company elected to classify some of its securities purchased during 2021 and 2020 as held to maturity. These are securities that the Company does not intend to sell and expects to hold to maturity. The securities consist of $112.9 million of agency securities and $1.6 billion of residential and commercial mortgage-backed securities issued by U.S government agencies or sponsored enterprises and $62.6 million of Small Business Administration loan-backed securities. The following are highlights of our held to maturity portfolio:

| ● | Total held to maturity portfolio totaled $1.8 billion.

| ● | The balance of securities held to maturity represented 4.3% of total assets at December 31, 2021.

| ● | We purchased $975.3 million of held to maturity investment securities in 2021, partially offset by maturities, calls and paydowns totaling $105.0 million in 2021.

Available for sale

Securities available for sale consist mainly of debentures of government sponsored entities, state and municipal bonds, residential and commercial mortgage-backed securities issued by U.S government agencies or sponsored enterprises and Small Business Administration loan-backed securities. At December 31, 2021, investment securities with both a fair value and amortized cost of $5.2 billion, were classified as available for sale. The adjustment for net unrealized losses of $27.8 million between the carrying value of these securities and their amortized cost has been reflected, net of tax, in the Consolidated Balance Sheet as a component of Accumulated Other Comprehensive Loss. The following are highlights of our available for sale securities:

| ● | Total securities available for sale increased $1.9 billion, or 55.9%, from the balance at December 31, 2020. The unrealized gain/loss position on the investment portfolio decreased $90.5 million and net amortization of premiums was $32.1 million during 2021. We purchased $2.9 billion of available for sale investment securities in 2021, partially offset by maturities, calls and paydowns totaling $805.3 million and sales totaling $151.3 million in 2021. The sales in 2021 were mainly related to restructuring our portfolio to fit our investment strategy and risk profile.

| ● | The balance of securities available for sale represented 12.4% of total assets at December 31, 2021 and 8.8% of total assets at December 31, 2020.

| ● | Interest income earned on all investment securities in 2021 was $87.6 million, an increase of $32.9 million, or 60.3%, from $54.6 million in 2020. The increase was due to a $2.9 billion increase in average balances which was partially offset by a reduction in the yield on investment securities. The yield on investment securities declined 36 basis points during 2021, to 1.52%. In 2021, we used a portion of our excess liquidity from deposit growth to increase the size of our investment portfolio, and the 2021 purchases had lower yields compared to the existing portfolio resulting in a decrease in the overall yield of our investment portfolio.

Table of Contents

At December 31, 2021, we had 296 investment securities (including both available for sale and held to maturity) in an unrealized loss position, which totaled $106.0 million. See Note 3—Investment Securities in the consolidated financial statements for additional information. The increase in the number of securities in a loss position and the relative percentage of loss to portfolio size was primarily a result of the increase in short and long-term interest rates during 2021.

Management evaluates securities for impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby Management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the provision for credit losses. Consideration is given to (1) the financial condition and near-term prospects of the issuer including looking at default and delinquency rates, (2) the outlook for receiving the contractual cash flows of the investments, (3) the length of time and the extent to which the fair value has been less than cost, (4) our intent and ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value or for a debt security whether it is more-likely-than-not that we will be required to sell the debt security prior to recovering its fair value, (5) the anticipated outlook for changes in the general level of interest rates, (6) credit ratings, (7) third-party guarantees, and (8) collateral values. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, the results of reviews of the issuer’s financial condition, and the issuer’s anticipated ability to pay the contractual cash flows of the investments. The Company performed an analysis that determined that the following securities have a zero expected credit loss: U.S. Treasury Securities, Agency-Backed Securities including securities issued by Ginnie Mae, Fannie Mae, FHLB, FFCB and SBA. All of the U.S. Treasury and Agency-Backed Securities have the full faith and credit backing of the United States Government or one of its agencies. Municipal securities and all other securities that do not have a zero expected credit loss are evaluated quarterly to determine whether there is a credit loss associated with a decline in fair value. All debt securities in an unrealized loss position as of December 31, 2021 continue to perform as scheduled and we do not believe there is a credit loss or a provision for credit losses is necessary.

​

Also, as part of our evaluation of our intent and ability to hold investments for a period of time sufficient to allow for any anticipated recovery in the market, we consider our investment strategy, cash flow needs, liquidity position, capital adequacy and interest rate risk position. We do not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that we will be required to sell the debt securities. See Note 1—Summary of Significant Account Policies for further discussion.

Other Investments

Our other investment securities consist of non-marketable equity securities that have no readily determinable market value. Accordingly, when evaluating these securities for impairment, Management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. As of December 31, 2021, we determined that there was no impairment on our other investment securities. As of December 31, 2021, other investment securities represented approximately $160.6 million, or 0.38% of total assets and primarily consisted of FRB and FHLB stock which totals $129.7 million and $16.3 million, respectively. There were no gains or losses on the sales of these securities during 2021 or 2020.

Loan Portfolio

Our loan portfolio remains our largest category of interest-earning assets. At December 31, 2021, total loans, excluding held for sale loans, were $23.9 billion, which was an overall decrease of $736.0 million, or 3.0%, from the balance at the end of 2020. Non-acquired loan growth was $3.8 billion, or 30.6% for 2021, which was made up of a 21.5% increase in consumer real estate loans, a 55.0% increase in non-owner occupied real estate loans (including construction and land development loans), a 36.9% increase in commercial owner occupied real estate loans, a 5.4% increase in commercial and industrial loans, a 31.4% increase in other income producing property and a 16.9% increase in consumer non real estate loans. The increases in non-acquired loans were due to organic growth and renewals of acquired loans that are moved to our non-acquired loan portfolio. Total acquired loans decreased by $4.5 billion. The decreases in acquired loans were due to principal payments, charge offs, foreclosures and renewals of acquired loans that were moved to our non-acquired loan portfolio.

Acquired loans as a percentage of total loans decreased to 32.9% at December 31, 2021 compared to 50.2% at December 31, 2020. As of December 31, 2021, non-acquired loans as a percentage of the overall portfolio were 67.1% compared to 49.8% at December 31, 2020. Average total loans outstanding during 2021 were $24.1 billion, increasing $4.7 billion, or 24.5%, over the 2020 average of $19.4 billion.

The following highlights of our loan portfolio as of December 31, 2021 compared to December 31, 2020:

| ● | Non-acquired loans were $16.1 billion, or 67.1% of total loans and acquired loans were $7.9 billion, or 32.9% of total loans at December 31, 2021. This compared to non-acquired loans of $12.3 billion, or 49.8% and acquired loans of $12.4 billion, or 50.2% at December 31, 2020. The increase in non-acquired loans of $3.8 billion was due to organic growth and renewals of acquired loans that were moved to the non-acquired loan portfolio. This increase was net of a reduction in non-acquired PPP loans of $729.0 million in 2021 through pay-off and loan forgiveness. Therefore, excluding PPP loan activity, non-acquired loans increased $4.5 billion. Total acquired loans declined by $4.5 billion, as compared to the same period in 2020. The decrease in acquired loans was due to principal payments, charge offs, foreclosures and renewals of acquired loans that were moved to our non-acquired loan portfolio. The decline also included a reduction of acquired PPP loans of $959.8 million through pay-off and forgiveness of the loans.

| ● | Non-acquired loans secured by non-owner occupied and consumer real estate were $9.0 billion and comprised 37.6% of the total loan portfolio. This was an increase of $2.6 million, or 40.5%, over December 31, 2020. Acquired loans secured by non-owner occupied and consumer real estate were $4.6 billion and comprised 19.2% of the total loan portfolio. This was a decrease of $2.0 million, or 30.8%, over December 31, 2020. Between both the non-acquired and acquired portfolios, 56.7% of loans were non-owner occupied and consumer real estate loans.

| o | Of these non-acquired real estate loans, $5.6 billion, or 23.5% of the loan portfolio were secured by non-owner occupied real estate. Loans secured by consumer real estate were $3.4 billion, or 14.1% of the total

|  | loan portfolio. This compared to loans secured by non-owner occupied real estate of $3.6 billion, or 14.7% and to loans secured by consumer real estate of $2.8 billion, or 11.2% at December 31, 2020.

| o | Of these acquired real estate loans, $3.1 billion, or 13.2% of the loan portfolio were secured by non-owner occupied real estate at December 31, 2021. Loans secured by consumer real estate were $1.4 billion, or 6.0%. This compared to acquired loans secured by non-owner occupied real estate of $4.4 billion, or 17.9% and to loans secured by consumer real estate of $2.2 billion, or 8.9% at December 31, 2020.

| ● | Non-acquired and acquired commercial owner-occupied real estate loans were $3.1 billion, or 13.0% and $1.9 billion or 7.8%, respectively, of the total loan portfolio at December 31, 2021 compared to $2.3 billion, or 9.2% and $2.6 billion or 10.4%, respectively, at December 31, 2020. Non-acquired commercial owner-occupied real estate loans increased $835.5 million through organic growth and renewals of acquired loans and acquired commercial owner-occupied real estate loans decreased $698.1 million due to principal payments, charge offs, foreclosures and renewals of acquired loans that were moved to our non-acquired loan portfolio from December 31, 2020 compared to December 31, 2021.

| ● | Non-acquired and acquired commercial and industrial loans were $2.9 billion, or 12.1% and $855.5 million or 3.6%, respectively, of the total loan portfolio at December 31, 2021 compared to $2.8 billion, or 11.2% and $2.3 billion or 9.3%, respectively, at December 31, 2020. Non-acquired commercial and industrial loans increased $149.9 million and acquired commercial and industrial loans decreased $1.4 billion from December 31, 2020 compared to December 31, 2021. The overall increase in non-acquired commercial and industrial loans included a $729.0 million decline in PPP loans while the overall decrease in acquired commercial and industrial loans included a $959.8 million decline in PPP loans.

Total loan interest income, excluding interest income on held for sale loans, was $983.7 million in 2021, an increase of $140.8 million, or 16.7%, over $842.9 million in 2020, due to a $3.4 billion increase in the average balance of our non-acquired loan portfolio and a $1.4 billion increase in the average balance of our acquired loan portfolio. The growth in the non-acquired loan portfolio average balance was due to normal organic growth and renewals of acquired loans. The growth in the acquired loan portfolio was due to the merger with CSFL that occurred during June of 2020 where the Company acquired approximately $13.0 billion in loans. The effects on interest income from the increases in average portfolio balances were offset by a 12 basis point decrease in the yield on the non-acquired portfolio and a 41 basis point decrease in the yield on the acquired portfolio. The yield on the non-acquired loan portfolio decreased from 3.91% in 2020 to 3.79% in 2021 and the yield on the acquired loan portfolio declined from 4.90% in 2020 to 4.49% in 2021. The decline in the yields on the non-acquired loan portfolio and the acquired loan portfolio was mainly due to the falling interest rate environment as the Federal Reserve dropped the federal funds target rate 150 basis points to a range of 0.00% to 0.25% in March 2020 in reaction to the COVID-19 pandemic, and remains unchanged to date.

Total construction and land development loans were $2.0 billion at December 31, 2021 compared to $1.9 billion at December 31, 2020. Non-acquired construction and land development loans increased $509.0 million in 2021 from $1.3 million at December 31, 2020 to $1.8 billion. Acquired construction and land development loans decreased $370.7 million in 2021 from $610.8 million at December 31, 2020 to $240.1 million. Construction and land development loans are more susceptible to a risk of loss during a downturn in the business cycle.

Total consumer real estate loans were comprised of $3.6 billion in consumer owner occupied loans and $1.2 billion in home equity line loans at December 31, 2021. This compares to $3.7 billion in consumer owner occupied loans and $1.3 billion in home equity lines loans at December 31, 2020. Non-acquired loans secured by consumer real estate were comprised of $2.7 billion in consumer owner occupied loans and $710.3 million in home equity loans at December 31, 2021. At December 31, 2020, we had $2.2 billion in consumer owner occupied loans and $601.2 million in home equity loans in the non-acquired loan portfolio. Acquired loans secured by consumer real estate comprised of $977.3 million in consumer owner occupied loans and $458.3 million in home equity loans at December 31, 2021. At December 31, 2020, we had $1.5 billion in consumer owner occupied loans and $690.9 million in home equity loans in the acquired loan portfolio. During 2021, we have seen the consumer real estate loan portfolio decrease by $167.9 million from 2020 as consumers have paid down debt with all the excess liquidity in the marketplace in 2021 through government stimulus and conservative consumer spending habits during the COVID-19 pandemic.

Troubled Debt Restructurings (“TDRs”)

We designate expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals, or modifications, unless the Company reasonably expects it will execute a TDR with a borrower. In the event of a reasonably-expected TDR, the Company factors the reasonably-expected TDR into the current expected credit losses estimate. For consumer loans, the point at which a TDR is reasonably expected is when the Company approves the borrower’s application for a modification (i.e., the borrower qualifies for the TDR) or when the Credit Administration department approves loan concessions on substandard loans. For commercial loans, the point at which a TDR is reasonably expected is when the Company approves the loan for modification or when the Credit Administration department approves loan concessions on substandard loans. The Company uses a discounted cash flow methodology for a TDR to calculate the effect of the concession provided to the borrower within the ACL.

A restructuring that results in only a delay in payments that is insignificant is not considered an economic concession. In accordance with the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, the Company implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. The Company’s payment relief assistance includes forbearance, deferrals, extension and re-aging programs, along with certain other modification strategies. The Company elected the accounting policy in the CARES Act to not apply TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic if the concession met the criteria as defined under the CARES Act. At December 31, 2021 and 2020, total TDRs were $12.5 million and $19.7 million, respectively, of which $11.2 million were accruing restructured loans at December 31, 2021, compared to $14.6 million at December 31, 2020. We do not have significant commitments to lend additional funds to these borrowers whose loans have been modified.

Total non-acquired nonperforming loans were $23.3 million, or 0.15% of total non-acquired loans, a decrease of approximately $5.9 million, or 20.1%, from December 31, 2020. The decrease in nonperforming loans was driven primarily by a decrease in accruing loans past due 90 days or more of $5.0 million, a decrease in restructured nonaccrual loans of $3.1 million, a decrease in consumer nonaccrual loans of $1.3 million, offset by an increase in commercial nonaccrual loans of $3.5 million. The decline in non-acquired accruing loans past due 90 days or more from 2020 was due to a decline in past due loans related to financing receivables from CBI. These loans are deemed low risk and their past due status can fluctuate due to the type of factoring receivable. Acquired nonperforming loans were $57.0 million, or 0.72% of total acquired loans, a decrease of $20.7 million, or 26.7%, from December 31, 2020. The decrease in acquired nonperforming loans was mainly driven by a decrease in consumer nonaccrual loans of $16.1 million, a decrease in commercial nonaccrual loans of $2.7 million and a decrease in accruing loans past due 90 days or more of $1.8 million. The decline in acquired consumer nonaccrual loans was mostly related to a decline in nonaccrual consumer real estate loans in 2021.

Non-acquired nonperforming loans decreased by approximately $2.2 million during the fourth quarter of 2021 from the level at September 30, 2021. The decrease was mainly due to a decrease in consumer nonaccrual loans of $3.9 million, a decrease in restructured nonaccrual loans of $1.2 million, offset by an increase in accruing loans past due 90

days or more of $2.9 million. Acquired nonperforming loans decreased by approximately $7.7 million during the fourth quarter of 2021 from the level at September 30, 2021. The decrease was mainly due to a decrease in consumer nonaccruals of $6.4 million and a decrease in commercial nonaccruals of $1.4 million. The top ten nonaccrual loans at December 31, 2021 totaled $20.0 million and consisted of two loans located in South Carolina, four in the Georgia, and four in Florida. These loans comprise 26.5% of total nonaccrual loans at December 31, 2021, with the majority being real estate collateral dependent. We do not currently hold a specific reserve against any of these ten loans due to carrying balances being below current collateral values.

At December 31, 2021, non-acquired OREO decreased by $300,000 from the balance at December 31, 2020 to $252,000. At December 31, 2021, non-acquired OREO consisted of one property with an average value of $252,000, an increase of $173,000 in the average value from December 31, 2020 when we had 7 properties. In the fourth quarter of 2021, we added one property with an aggregate value of $252,000 into non-acquired OREO, and we sold two properties with a basis of $81,000 in that same quarter. We recorded a net gain of $6,000 on the properties sold during the fourth quarter of 2021. Our non-acquired OREO property at December 31, 2021 is located in the Central region (Columbia, SC).

At December 31, 2021, acquired OREO decreased by $8.9 million from the balance at December 31, 2020 to $2.5 million. At December 31, 2021, non-acquired OREO consisted of 11 properties with an average value of $226,000, a decrease of $99,000 from December 31, 2020 when we had 35 properties. In the fourth quarter of 2021, we added two properties with an aggregate value of $874,000 into acquired OREO, and we sold 12 properties with a basis of $1.7 million in that same quarter. We recorded a net gain of $618,000 on the properties sold during the quarter. Our general policy is to obtain updated OREO valuations at least annually. OREO valuations include appraisals or broker opinions, (See Other Real Estate Owned (“OREO”) under Critical Accounting Policies and Estimates in Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations for further discussion on our OREO policies.)

Potential Problem Loans

Potential problem loans, which are not included in nonperforming loans, related to non-acquired loans were approximately $6.9 million, or 0.04% of total non-acquired loans outstanding at December 31, 2021, compared to $5.9 million, or 0.05% of total non-acquired loans outstanding at December 31, 2020. Potential problem loans related to acquired loans totaled $19.3 million, or 0.24%, of total acquired loans at December 31, 2021, compared to $13.4 million, or 0.11% of total acquired loans outstanding, at December 31, 2020. All potential problem loans represent those loans where information about possible credit problems of the borrowers has caused Management to have concern about the borrower’s ability to comply with present repayment terms.

Allowance for Credit Losses (“ACL”)

As stated previously, the ACL reflects Management’s estimate of expected credit losses that will result from the inability of our borrowers to make required loan payments. At adoption of ASU 2016-13, the Company established the incremental increase in the ACL through equity and subsequent adjustments through a provision for or recovery of credit losses recorded to earnings. The Company records loans charged off against the ACL and subsequent recoveries, if any, increase the ACL when they are recognized.

Management uses systematic methodologies to determine its ACL for loans held for investment and certain off-balance-sheet credit exposures. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loan portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may result in a range of expected credit losses. The Company’s ACL recorded in the balance sheet reflects Management’s best estimate within the range of expected credit losses. The Company recognizes in net income the amount needed to adjust the ACL for Management’s current estimate of expected credit losses. The Company’s ACL is calculated using collectively evaluated and individually evaluated loans.

The Company merged with CSFL on June 7, 2020. For the second quarter ended June 30, 2020, given the proximity of the merger date to the quarter end, Management collectively evaluated loans from each legacy loan portfolio utilizing pre-existing methodologies implemented prior to the merger and aggregated the result. During the third quarter of 2020, Management consolidated the two methodologies into one to arrive at the ACL recorded at September 30, 2020 for both the ACL related to the loan portfolio and the reserve related to the unfunded commitments

78

Table of Contents

(off-balance-sheet credit exposures). The new methodology for unfunded commitments utilizes a funding rate, as opposed to a utilization rate which was a method applied to the SouthState legacy portfolio prior to the third quarter, to determine the reserve for each respective segment of unfunded commitments. This new method, along with the change in mix of unfunded commitments, resulted in an increase in the reserve for legacy SouthState Bank unfunded commitments during the third quarter of 2020.

The allowance for credit losses is measured on a collective pool basis when similar risk characteristics exist. Loans with similar risk characteristics are grouped into homogenous segments, or pools, for analysis. The Discounted Cash Flow (“DCF”) method is utilized for each loan in a pool, and the results are aggregated at the pool level. A periodic tendency to default and absolute loss given default are applied to a projective model of the loan’s cash flow while considering prepayment and principal curtailment effects. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information (e.g., maturity date, payment amount, interest rate, etc.) with top-down pool assumptions (e.g., default rates and prepayment speeds). The Company has identified the following portfolio segments: Owner-Occupied Commercial Real Estate, Non Owner-Occupied Commercial Real Estate, Multifamily, Municipal, Commercial and Industrial, Commercial Construction and Land Development, Residential Construction, Residential Senior Mortgage, Residential Junior Mortgage, Revolving Mortgage, and Consumer and Other.

In determining the proper level of the ACL, Management has determined that the loss experience of the Bank provides the best basis for its assessment of expected credit losses. It therefore utilized its own historical credit loss experience by each loan segment over an economic cycle, while excluding loss experience from certain acquired institutions (i.e., failed banks). For most of the segment models for collectively evaluated loans, the Company incorporated two or more macroeconomic drivers using a statistical regression modeling methodology.

Management considers forward-looking information in estimating expected credit losses. The Company subscribes to a third-party service which provides a quarterly macroeconomic baseline outlook and alternative scenarios for the United States economy. The baseline, along with the evaluation of alternative scenarios, is used by Management to determine the best estimate within the range of expected credit losses. Management has evaluated the appropriateness of the reasonable and supportable forecast scenarios and has made adjustments as needed. Management evaluates the appropriateness of the reasonable and supportable forecast scenarios and takes into consideration the scenarios in relation to actual economic and other data (such as COVID-19 epidemiological data and federal stimulus), as well as the volatility and magnitude of changes within those scenarios quarter over quarter, and consideration of condition within the bank’s operating environment and geographic area. Additional forecast scenarios may be weighed along with the baseline forecast to arrive at the final reserve estimate. While periods of relative economic stability should generally lead to stability in forecast scenarios and weightings to estimate credit losses, periods of instability can likewise require Management to adjust the selection of scenarios and weightings, in accordance with the accounting standards. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to the long term mean of historical factors within four quarters using a straight-line approach. The Company generally utilizes a four-quarter forecast and a four-quarter reversion period.

The COVID-19 pandemic has created increased volatility and uncertainties within the economy and economic forecasts. Accordingly, Management has used a blended forecast scenario of the baseline and more severe scenario ranging between two-thirds baseline and one-third more severe scenario to an equal weight between the baseline and more severe scenario since December 31, 2020, depending on the circumstances and economic outlook. As of December 31, 2021, Management selected a baseline weighting of 55%, down from 60% in the third quarter of 2021, and increased the more severe scenario to 45%, as several issues have materialized that warrant a more cautious approach. These issues include, but are not limited to, level of optimism in the baseline forecast outlook as compared to consensus forecasts; political impediments to moving the Build Back America legislation forward; persistent headwinds related to the Omicron variant of COVID-19; and growing evidence that inflationary pressures in the labor market and supply chains are more than transitory. The resulting release was approximately $9.2 million during the fourth quarter of 2021. If the economic forecast weighting had not been adjusted from the third quarter of 2021, this would have resulted in a higher release of approximately $13.4 million, which Management deemed inappropriate given the underlying economic conditions and likelihood of additional stimulus as compared with assumptions in the baseline scenario.

Included in its systematic methodology to determine its ACL, Management considers the need to qualitatively adjust expected credit losses for information not already captured in the loss estimation process. These qualitative adjustments either increase or decrease the quantitative model estimation (i.e., formulaic model results). Each period the

79

Table of Contents

Company considers qualitative factors that are relevant within the qualitative framework that includes the following: 1) Lending Policy; 2) Economic conditions not captured in models; 3) Volume and Mix of Loan Portfolio; 4) Past Due Trends; 5) Concentration Risk; 6) External Factors; and 7) Model Limitations.

When a loan no longer shares similar risk characteristics with its segment, the asset is assessed to determine whether it should be included in another pool or should be individually evaluated. The Company’s threshold for individually-evaluated loans includes all non-accrual loans with a net book balance in excess of $1.0 million. Management will monitor the credit environment and make adjustments to this threshold in the future if warranted. Based on the threshold above, consumer financial assets will generally remain in pools unless they meet the dollar threshold. The expected credit losses on individually-evaluated loans will be estimated based on discounted cash flow analysis unless the loan meets the criteria for use of the fair value of collateral, either by virtue of an expected foreclosure or through meeting the definition of collateral-dependent. Financial assets that have been individually evaluated can be returned to a pool for purposes of estimating the expected credit loss insofar as their credit profile improves and that the repayment terms were not considered to be unique to the asset.

Management measures expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals, or modifications, unless the Company reasonably expects it will execute a troubled debt restructuring (“TDR”) with a borrower. In the event of a reasonably-expected TDR, the Company factors the reasonably-expected TDR into the current expected credit losses estimate. For consumer loans, the point at which a TDR is reasonably expected is when the Company approves the borrower’s application for a modification (i.e., the borrower qualifies for the TDR) or when the Credit Administration department approves loan concessions on substandard loans. For commercial loans, the point at which a TDR is reasonably expected is when the Company approves the loan for modification or when the Credit Administration department approves loan concessions on substandard loans. The Company uses a discounted cash flow methodology for a TDR to calculate the effect of the concession provided to the borrower within the ACL.

A restructuring that results in only a delay in payments that is insignificant is not considered an economic concession. In accordance with the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, the Company implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. The Company’s payment relief assistance includes forbearance, deferrals, extension and re-aging programs, along with certain other modification strategies. The Company elected the accounting policy in the CARES Act to not apply TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic if the concession met the criteria as defined under the CARES Act.

For purchased credit-deteriorated, otherwise referred to herein as PCD, assets are defined as acquired individual financial assets (or acquired groups of financial assets with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by the Company’s assessment. The Company records acquired PCD loans by adding the expected credit losses (i.e., allowance for credit losses) to the purchase price of the financial assets rather than recording through the provision for credit losses in the income statement. The expected credit loss, as of the acquisition day, of a PCD loan is added to the allowance for credit losses. The non-credit discount or premium is the difference between the unpaid principal balance and the amortized cost basis as of the acquisition date. Subsequent to the acquisition date, the change in the ACL on PCD loans is recognized through the provision for credit losses. The non-credit discount or premium is accreted or amortized, respectively, into interest income over the remaining life of the PCD loan on a level-yield basis. In accordance with the transition requirements within the standard, the Company’s acquired credit-impaired loans (i.e., ACI or Purchased Credit Impaired) were treated as PCD loans.

The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Therefore, Management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the portfolio and does not record an allowance for credit losses on accrued interest receivable. As of December 31, 2021 and 2020, the accrued interest receivable for loans recorded in Other Assets were $70.6 million and $93.9 million, respectively.

The Company has a variety of assets that have a component that qualifies as an off-balance sheet exposure. These primarily include undrawn portions of revolving lines of credit and standby letters of credit. The expected losses associated with these exposures within the unfunded portion of the expected credit loss will be recorded as a liability on the balance sheet. Management has determined that a majority of the Company’s off-balance-sheet credit exposures are not unconditionally cancellable. Management completes funding studies based on historical data to estimate the

Table of Contents

percentage of unfunded loan commitments that will ultimately be funded to calculate the reserve for unfunded commitments. Management applies this funding rate, along with the loss factor rate determined for each pooled loan segment, to unfunded loan commitments, excluding unconditionally cancellable exposures and letters of credit, to arrive at the reserve for unfunded loan commitments. As of December 31, 2021 and 2020, the liabilities recorded for expected credit losses on unfunded commitments were $30.5 million and $43.4 million, respectively. The current adjustment to the ACL for unfunded commitments is recognized through the Provision for Credit Losses in the Consolidated Statements of Income. The Company did not have an allowance for credit losses or record a provision for credit losses on investment securities or other financials asset during 2021.

With the adoption of ASU 2016-13 on January 1, 2020, the Company changed its method for calculating the allowance for loans from an incurred loss method to a life of loan method. See Note 1—Significant Accounting Policies. As of December 31, 2021, the balance of the ACL was $301.8 million or 1.26% of total loans. The ACL decreased $12.3 million from the balance of $314.1 million recorded at September 30, 2021. This decrease during the fourth quarter of 2021 included an $11.4 million release or decline in the provision for credit losses in addition to $1.0 million in net charge-offs. For the year ended December 31, 2021, the ACL decreased $155.5 million from the balance of $457.3 million. The decrease in ACL of $155.5 million was due to a release of the allowance for credit losses of $152.4 million along with net charge-offs of $3.1 million in 2021. For both the three and twelve months ended December 30, 2021, the Company had releases of allowance for credit losses resulting from improvements in the economic forecasts that drive our ACL model. The improvement in the economy and the increased availability and higher percentage of people receiving the COVID-19 vaccine and boosters contributed to the change in the economic forecasts. As of December 31, 2020, the balance of the ACL was $457.3 million or 1.85% of total loans. For the year ended December 31, 2020, the ACL increased $400.1 million from the balance of $56.9 million. This increase included a $199.4 million provision for credit losses during the period (which includes $109.4 million of provision recorded for non-PCD loans acquired through the merger with CSFL), a $149.4 million allowance for credit losses recorded on acquisition date on PCD loans acquired from CSFL and an increase of $54.5 million through the impact of the initial adoption of CECL. These increases in 2020 were partially offset by $2.8 million in net charge-offs.

​

At December 31, 2021, the Company had a reserve on unfunded commitments of $30.5 million which was recorded as a liability on the Consolidated Balance Sheet, compared to $43.4 million at December 31, 2020. During the year ended December 31, 2021, the Company recorded a release of the reserve for unfunded commitments, or recovery for credit losses, on unfunded commitments of $12.9 million. With the improvement in the economy and the increased availability of the COVID-19 vaccine, the Company began to release some of this reserve for unfunded commitments based on improvements in economic forecasts. This amount was recorded in (Recovery) Provision for Credit Losses on the Consolidated Statements of Income. With the adoption of ASU 2016-13 on January 1, 2020, the Company increased its reserve on unfunded commitments by $6.5 million. During the year ended December 31, 2020, the provision for credit losses on unfunded commitments was $36.6 million. Included in the provision for credit losses for the year ended December 31, 2020, $9.6 million was related to the merger with CSFL, which was completed during the second quarter of 2020. The Company did not have an allowance for credit losses or record a provision for credit losses on investment securities or other financials asset during the first nine months of 2021 or 2020.

​

For the year ended December 31, 2021, the allowance for credit losses was $301.8 million, or 1.26%, of period-end loans. The ACL provides 3.76 times coverage of nonperforming loans at December 31, 2021, compared to 4.28 times at December 31, 2020. Net charge offs to total average loans during the year ended December 31, 2021 were 0.01%, the same percentage as for the year ended December 31, 2020. We continued to show solid and stable asset quality numbers and ratios as of December 31, 2021. The following table provides the allocation, by segment, for expected credit losses. Because PPP loans are government guaranteed and Management implemented additional reviews and procedures to help mitigate potential losses, Management does not expect to recognize credit losses on this loan portfolio and as a result, did not record an ACL for PPP loans within the C&I loan segment presented in the table below.

During 2019, the valuation allowance on acquired credit impaired loans increased by $460,000, or 10.0%. This was the result of impairments of $1.2 million which were recorded through the provision for loan losses, being offset by loan removals of $723,000 due to loans being paid off, fully charged off or transferred to OREO. Impairments are recognized immediately and releases are generally spread over time.

Deposits

We rely on deposits by our customers as the primary source of funds for the continued growth of our loan and investment securities portfolios. Customer deposits are categorized as either noninterest-bearing deposits or interest-bearing deposits. Noninterest-bearing deposits (or demand deposits) are transaction accounts that provide us with “interest-free” sources of funds. Interest-bearing deposits include savings deposit, interest-bearing transaction accounts, certificates of deposits, and other time deposits. Interest-bearing transaction accounts include HSA, IOLTA, and Market Rate checking accounts.

During 2021, all categories of deposits increased from 2020 except for time deposits. Total deposits increased $4.4 billion, or 14.2%, to $35.1 billion during 2021. The year-over-year growth was primarily due to the federal government pushing funds into the market through stimulus programs, in addition to consumers remaining conservative in their spending habits in reaction to the COVID-19 pandemic. Our deposit growth since December 31, 2020 included an increase in interest-bearing demand deposits of $2.9 billion, noninterest-bearing transaction account deposits of $1.8 billion, and saving deposits of $656.5 million. These increases were offset by a decline in time deposits of $938.5 million. During 2021, we continued our focus on increasing core deposits (excluding certificates of deposits and other time deposits), which are normally lower cost funds compared to certificate of deposit balances.

The following table presents total deposits for the two years at December 31:

At December 31, 2021 and 2020, the Company estimates that is has approximately $12.4 billion and $10.0 billion, respectively, in uninsured deposits including related interest accrued and unpaid. Since it is not reasonably practicable to provide a precise measure of uninsured deposits, the amounts above are estimates and are based on the same methodologies and assumptions used for the bank’s regulatory reporting requirements by the FDIC for the Call Report.

Short-Term Borrowed Funds

Our short-term borrowed funds consist of federal funds purchased and securities sold under repurchase agreements, FRB borrowings on a secured line of credit, short-term FHLB Advances and the U.S. Bank line of credit. Note 10—Federal Funds Purchased and Securities Sold Under Agreements to Repurchase in our audited financial statements provides a profile of these funds at each year-end, the average amounts outstanding during each period, the maximum amounts outstanding at any month-end, and the weighted average interest rates on year-end and average balances in each category. Federal funds purchased and securities sold under agreements to repurchase most typically have maturities within one to three days from the transaction date. Certain of these borrowings have no defined maturity date. Note 11—Other Borrowings in our audited financial statements provide provides a profile of short-term FHLB advances, FRB borrowings and the U.S. Bank line of credit at each year-end, the average amount outstanding during each period and the weighted average interest rates on year-end and average balance. Short-term FHLB advances have a maturity of less than one year and the FRB borrowings and U.S. Bank line of credit had a daily maturity.

Long-Term Borrowed Funds

Our long-term borrowed funds consist of trust preferred junior subordinated debt and corporate subordinated debt. Note 11—Other Borrowings in our audited financial statements provides a profile of these funds at each year-end, the balance at year end, the interest rate at year end and the weighted average interest rate for long-term borrowings. Each issuance of trust preferred junior subordinated debt has a maturity of 30 years, but we can call the debt at any point without penalty.

Capital and Dividends

Our ongoing capital requirements have been met primarily through retained earnings, less the payment of cash dividends. As of December 31, 2021, shareholders’ equity was $4.8 billion, an increase of $155.1 million, or 3.3%, compared to the balance at December 31, 2020. The change from year-end 2020 was mainly attributable to net income of $475.5 million, less dividends paid on common shares of $135.2 million, common stock repurchased under our stock repurchase plan of $146.4 million and a decline in the AOCI attributable to a decrease in the market value of securities available for sale of $68.9 million.

The following shows the changes in shareholders’ equity during 2021:

Our equity-to-assets ratio decreased to 11.4% at December 31, 2021 from 12.3% at December 31, 2020. The decrease from December 31, 2020 was due to the percentage increase in equity of 3.3% being less than the percentage increase in total assets of 11.0%. The increase in assets was mainly due to the increase in cash and cash equivalents and investment securities as deposits grew 14.2% providing the bank with excess liquidity during 2021. The lower percentage growth in capital was mainly due to the Company repurchasing $146.4 million in common stock through its stock repurchase plan and paying dividends on common shares of $135.2 million in 2021.

On January 25, 2019, our Board of Directors approved a program (“2019 Repurchase Program”) to repurchase up to 1,000,000 of our common stock. In June 2019, our Board of Directors authorized the repurchase of up to an additional 2,000,000 shares of our common stock under the Company’s 2019 Repurchase Program after considering,

among other things, our liquidity needs and capital resources as well as the estimated current value of our net assets. In 2019, the Company repurchased a total of 2,165,000 shares for $156.9 million, or $72.49 per share (excluding commission expense), of which 1,000,000 shares were from the 2019 Repurchase Program and the remaining 1,165,000 shares were from the revised 2019 Repurchase Program. The Company repurchased an additional 320,000 shares for $24.7 million, or $77.23 per share (excluding commission expense) in 2020 under the 2019 Repurchase Program for a total of 1,485,000 repurchased under the 2,000,000 authorized. On January 27, 2021, the Board of Directors of the Company approved the authorization of a new 3,500,000 million share Company stock repurchase plan, which replaced in its entirety the 2019 Repurchase Program. As of December 31, 2021, we repurchased 1,817,941 shares, at an average price of $80.51 per share, excluding cost of commissions, for a total of $146.4 million, under the 2021 Stock Repurchase Plan and may repurchase up to an additional 1,682,059 shares of common stock under the program. The number of shares to be purchased and the timing of the purchases during 2021, 2020 and 2019 were based on a variety of factors, including, but not limited to, the level of cash balances, general business conditions, regulatory requirements, the market price of our common stock, and the availability of alternative investment opportunities.

​

We are subject to regulations with respect to certain risk-based capital ratios. These risk-based capital ratios measure the relationship of capital to a combination of balance sheet and off-balance sheet risks. The values of both balance sheet and off-balance sheet items are adjusted based on the rules to reflect categorical credit risk. In addition to the risk-based capital ratios, the regulatory agencies have also established a leverage ratio for assessing capital adequacy. The leverage ratio is equal to Tier 1 capital divided by total consolidated on-balance sheet assets (minus amounts deducted from Tier 1 capital). The leverage ratio does not involve assigning risk weights to assets.

​

Specifically, we are required to maintain the following minimum capital ratios:

​

| • | a CET1, risk-based capital ratio of 4.5%;

| • | a Tier 1 risk-based capital ratio of 6%;

| • | a total risk-based capital ratio of 8%; and

| • | a leverage ratio of 4%.

Under the current capital rules, Tier 1 capital includes two components: CET1 capital and additional Tier 1 capital. The highest form of capital, CET1 capital, consists solely of common stock (plus related surplus), retained earnings, accumulated other comprehensive income, otherwise referred to as AOCI, and limited amounts of minority interests that are in the form of common stock. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, Tier 1 minority interests and grandfathered trust preferred securities (as discussed below). Tier 2 capital generally includes the allowance for loan losses up to 1.25% of risk-weighted assets, qualifying preferred stock, subordinated debt and qualifying tier 2 minority interests, less any deductions in Tier 2 instruments of an unconsolidated financial institution. Cumulative perpetual preferred stock is included only in Tier 2 capital, except that the capital rules permit bank holding companies with less than $15 billion in total consolidated assets to continue to include trust preferred securities and cumulative perpetual preferred stock issued before May 19, 2010 in Tier 1 Capital (but not in CET1 capital), subject to certain restrictions. With the merger with CSFL during the second quarter of 2020, the Company’s trust preferred securities no longer qualifies for Tier 1 capital and is now only included in Tier 2 capital for regulatory capital calculations. AOCI is presumptively included in CET1 capital and often would operate to reduce this category of capital. When the current capital rules were first implemented, the Bank exercised its one-time opportunity at the end of the first quarter of 2015 for covered banking organizations to opt out of much of this treatment of AOCI, allowing us to retain our pre-existing treatment for AOCI.

In order to avoid restrictions on capital distributions or discretionary bonus payments to executives, a banking organization must maintain a “capital conservation buffer” on top of its minimum risk-based capital requirements. This buffer must consist solely of Tier 1 Common Equity, but the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital), resulting in the following effective minimum capital plus capital conservation buffer ratios: (i) a CET1 capital ratio of 7.0%, (ii) a Tier 1 risk-based capital ratio of 8.5%, and (iii) a total risk-based capital ratio of 10.5%.

The Bank is also subject to the regulatory framework for prompt corrective action, which identifies five capital categories for insured depository institutions (well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) and is based on specified thresholds for each of the three risk-based regulatory capital ratios (CET1, Tier 1 capital and total capital) and for the leverage ratio.

The federal banking agencies revised their regulatory capital rules to (i) address the implementation of CECL; (ii) provide an optional three-year phase-in period for the adverse regulatory capital effects that banking organizations are expected to experience upon adopting CECL; and (iii) require the use of CECL in stress tests beginning with the 2020 capital planning and stress testing cycle for certain banking organizations that are subject to stress testing. CECL became effective for us on January 1, 2020 and the Company applied the provisions of the standard using the modified retrospective method as a cumulative-effect adjustment to retained earnings. Related to the implementation of ASU 2016-13, we recorded additional allowance for credit losses for loans of $54.4 million, deferred tax assets of $12.6 million, an additional reserve for unfunded commitments of $6.4 million and an adjustment to retained earnings of $44.8 million. Instead of recognizing the effects on regulatory capital from ASU 2016-13 at adoption, the Company initially elected the option for recognizing the adoption date effects on the Company’s regulatory capital calculations over a three-year phase-in.

​

In 2020, in response to the COVID-19 pandemic, the federal banking agencies issued a final rule for additional transitional relief to regulatory capital related to the impact of the adoption of CECL. The final rule provides banking organizations that adopt CECL in the 2020 calendar year with the option to delay for two years the estimated impact of CECL on regulatory capital, followed by the aforementioned three-year transition period to phase out the aggregate amount of benefit during the initial two-year delay for a total five-year transition. The estimated impact of CECL on regulatory capital (modified CECL transitional amount) is calculated as the sum of the impact on retained earnings upon adoption of CECL (CECL transitional amount) and the calculated change in the ACL relative to the ACL upon adoption of CECL multiplied by a scaling factor of 25%. The scaling factor is used to approximate the difference in the ACL under CECL relative to the incurred loss methodology. The modified CECL transitional amount will be calculated each quarter for the first two years of the five-year transition. The amount of the modified CECL transition amount will be fixed as of December 31, 2021, and that amount will be subject to the three-year phase-out. The Company chose the five-year transition method and is deferring the recognition of the effects from the adoption date and the change in the ACL relative to the ACL on adoption date for the first two years of application.

Table 26—Capital Adequacy Ratios

​

The following table presents our consolidated capital ratios under the applicable capital rules:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | December 31, |
(In percent) |  | 2021 |  | 2020 |  | 2019 |
Common equity Tier 1 risk-based capital | ​ | 11.75 | % | 11.77 | % | 11.30 | %
Tier 1 risk‑based capital |  | 11.75 | % | 11.77 | % | 12.25 | %
Total risk‑based capital |  | 13.56 | % | 14.24 | % | 12.78 | %
Tier 1 leverage |  | 8.05 | % | 8.27 | % | 9.73 | %

The Tier 1 leverage ratio and the total risk-based capital ratio both decreased compared to the ratios at December 31, 2020. The Common equity Tier 1 risk-based capital ratio and the Tier 1 risk-based capital ratio both stayed relatively flat in 2021 as they only declined 2 basis points. The Tier 1 leverage ratio decreased from 2020 as tier 1 capital (excluding the change in AOCI) increased by $191.5 million or 6.4%, while total average eligible assets increased $3.4 billion, or 9.3%. The Tier 1 leverage ratio declined as the percentage increase in Tier 1 risk-based capital was less than the percentage increase in the average assets for regulatory capital purposes. The increase in average assets was mainly due to an increase in cash and cash equivalents and investments from December 31, 2020 with deposits growing as the federal government has pushed funds into the market through stimulus programs, in addition to consumers remaining conservative in their spending habits. The lower percentage increase in Tier 1 risk-based capital was mainly due to the Company repurchasing 1,817,941 common shares for $146.4 million through its stock repurchase plan in 2021. The total risk-based capital ratio decreased in 2021 as total risk-weighted assets increased $1.7 billion or 6.5% while total risk-based capital (excluding the change in accumulated other comprehensive income, or AOCI) grew by $50.6 million or 1.4%. The decrease in the total risk-based capital ratio at the Company was due to the percentage increase in total risk-based capital being less than the percentage increase in total risk-based assets. The reason for the lower percentage increase in the total risk-based capital at the Company was due the redemption of $25.0 million in subordinated debt and $38.5 million in trust preferred securities during the second quarter of 2021 that was included in total risked-based capital along with the amount of allowance for credit losses eligible for capital purposes declining $77.3 million with the releases of provision in 2021. The lower percentage increase in Tier 1 risk-based capital was also due to the Company repurchasing 1,817,941 common shares for $146.4 million through its stock repurchase plan in 2021. The Common equity Tier 1 risk-based capital ratio and the Tier 1 risk-based capital ratio both stayed relatively flat in 2021 as they only declined 2 basis points as the percentage change in Tier 1 risk-based capital and the percentage change in total risk-based asset were approximately the same in 2021 compared to 2020. Our capital ratios are currently

well in excess of the minimum standards and continue to be in the “well capitalized” regulatory classification.

​

The Company pays cash dividends to shareholders from its assets, which are mainly provided by dividends from its banking subsidiary. However, certain restrictions exist regarding the ability of its subsidiary to transfer funds to the Company in the form of cash dividends, loans or advances. The approval of the OCC is required if the total of all dividends declared by the Bank in any calendar year exceeds the total of its net profits for that year combined with its retained net profits for the preceding two years, less any required transfers to surplus. The federal banking agencies have issued policy statements which provide that bank holding companies and insured banks should generally pay dividends only out of current earnings.

​

During 2021, the Bank paid dividends to SouthState totaling $200.0 million. The Bank was not required to get approval of the OCC to pay these dividends. We used these funds and excess cash to pay our dividend to shareholders of $135.3 million, repurchase shares of our common stock on the open market totaling $146.4 million and redeem $63.5 million in trust preferred securities and subordinated debentures. During first quarter of 2020, the Bank paid special dividends to the Company totaling $24.7 million for which SCBFI approval was not required. These funds were used to repurchase Company stock on the open market totaling $24.7 million during the first quarter of 2020. The Bank also paid a special dividend of $33.0 million during the first quarter of 2020 to provide the Company with more general operating liquidity during the COVID-19 pandemic. During 2019, the Bank paid special dividends to the Company totaling $157.0 million for which SCBFI approval was required. The Bank received approval from the SCBFI in June 2019 to pay an additional $60.0 million above current year net income in dividends to the Company. These funds were used to repurchase Company stock on the open market totaling $156.9 million during 2019.

The following table provides the amount of dividends and payout ratios for the years ended December 31:

Table 27—Dividends Paid to Common Shareholders

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31, |
(Dollars in thousands) |  | 2021 |  | 2020 |  | 2019 |

Dividend payout ratios | ​ |  | 28.43 | % |  | 81.45 | % |  | 30.94 | %

We retain earnings to have capital sufficient to grow our loan and investment portfolios and to support certain acquisitions or other business expansion opportunities. The dividend payout ratio is calculated by dividing dividends paid during the year by net income for the year.

Liquidity

Liquidity refers to our ability to generate sufficient cash to meet our financial obligations, which arise primarily from the withdrawal of deposits, extension of credit and payment of operating expenses. Liquidity risk is the risk that the Bank’s financial condition or overall safety and soundness is adversely affected by an inability (or perceived inability) to meet its obligations. Our Asset Liability Management Committee (“ALCO”) is charged with the responsibility of monitoring policies that are designed to ensure acceptable composition of our asset/liability mix. Two critical areas of focus for ALCO are interest rate sensitivity and liquidity risk management. We have employed our funds in a manner to provide liquidity from both assets and liabilities sufficient to meet our cash needs.

Asset liquidity is maintained by the maturity structure of loans, investment securities and other short term investments. Management has policies and procedures governing the length of time to maturity on loans and investments. As reported in Table 7, less than one percent of the investment portfolio contractually matures in one year or less. This segment of the portfolio consists mostly of municipal obligations along with some paydowns of mortgage-backed securities. There is also an additional amount of securities that could be called or prepaid, as well as expected monthly paydowns of mortgage backed securities. Normally, changes in the earning asset mix are of a longer term nature and are not utilized for day to day corporate liquidity needs.

Our liabilities provide liquidity on a day to day basis. Daily liquidity needs are met from deposit levels or from our use of federal funds purchased, securities sold under agreements to repurchase, interest-bearing deposits at other banks and other short term borrowings. We engage in routine activities to retain deposits intended to enhance our liquidity position. These routine activities include various measures, such as the following:

89

Table of Contents

| ● | Emphasizing relationship banking to new and existing customers, where borrowers are encouraged and normally expected to maintain deposit accounts with our Bank;

| ● | Pricing deposits, including certificates of deposit, at rate levels that will attract and /or retain balances of deposits that will enhance our Bank’s asset/liability management and net interest margin requirements; and

| ● | Continually working to identify and introduce new products that will attract customers or enhance our Bank’s appeal as a primary provider of financial services.

Our non-acquired loan portfolio increased by approximately $3.8 billion, or approximately 30.6%, compared to the balance at December 31, 2020. The non-acquired loan balance includes $228.9 million PPP loans outstanding at December 31, 2021. Excluding PPP loans, the non-acquired loan portfolio increased by $4.5 billion, or 39.6% from December 31, 2020. The increase in the non-acquired loan portfolio was due to organic growth and renewals of acquired loans that are moved to our non-acquired loan portfolio. The acquired loan portfolio decreased by $4.5 billion, or 36.3%, from the balance at December 31, 2020. This decrease was through principal paydowns, charge-offs, foreclosures and renewals of acquired loans that moved into our non-acquired loan portfolio.

Our investment securities portfolio increased $2.7 billion, or 61.3% compared to the balance at December 31, 2020. The increase in investment securities from December 31, 2020 was a result of the Company strategically investing its excess funds from continued deposit growth. During 2021, we purchased $3.9 billion of securities, $975.3 million classified as held to maturity and $2.9 billion classified as available for sale. These increases were partially offset by maturities, calls, sales and paydowns of investment securities totaling $1.1 billion. Net amortization of premiums were $38.0 million in 2021. Total cash and cash equivalents were $6.8 billion at December 31, 2021, compared to $4.6 billion at December 31, 2020. The growth in cash and cash equivalents and investment securities was driven by the $4.4 billion increase in deposits during 2021.

At December 31, 2021 and December 31, 2020, we had $325.0 million and $600.0 million of traditional, out–of-market brokered deposits. At December 31, 2021 and December 31, 2020, we had $900.1 million and $611.1 million, respectively, of reciprocal brokered deposits. Total deposits were $35.1 billion at December 31, 2021, an increase of $4.4 billion from $30.7 billion at December 31, 2020. Our deposit growth since December 31, 2020 included an increase in interest-bearing transaction accounts of $2.1 billion, an increase in demand deposit accounts of $1.8 billion, and an increase in savings and money market accounts of $1.4 billion partially offset by a decline in certificates of deposit of $938.5 million. Total short-term borrowings at December 31, 2021 were $781.2 million consisting of $381.2 million in federal funds purchased and $400.0 million in securities sold under agreements to repurchase. Corporate and subordinated debentures decreased approximately $63.1 million in 2021 as the Company redeemed $38.5 million in trust preferred securities and $25.0 million in subordinated debentures, in addition to the repayment of $11.0 million of subordinated notes that matured during the second quarter of 2021. With the redemption of the trust preferred securities, the remaining fair value mark on these borrowings of $11.7 was written off as an extinguishment of debt cost. To the extent that we employ other types of non-deposit funding sources, typically to accommodate retail and correspondent customers, we continue to take in shorter maturities of such funds. Our current approach may provide an opportunity to sustain a low funding rate or possibly lower our cost of funds but could also increase our cost of funds if interest rates rise.

Through the operations of our Bank, we have made contractual commitments to extend credit in the ordinary course of our business activities. These commitments are legally binding agreements to lend money to our customers at predetermined interest rates for a specified period of time. We manage the credit risk on these commitments by subjecting them to normal underwriting and risk management processes. We believe that we have adequate sources of liquidity to fund commitments that are drawn upon by the borrowers. In addition to commitments to extend credit, we also issue standby letters of credit, which are assurances to third parties that they will not suffer a loss if our customer fails to meet its contractual obligation to the third-party. Although our past experience indicates that many of these standby letters of credit will expire unused, through our various sources of liquidity, we believe that we will have the necessary resources to meet these obligations should the need arise.

Our ongoing philosophy is to remain in a liquid position as reflected by such indicators as the composition of our earning assets, typically including some level of reverse repurchase agreements, federal funds sold, balances at the Federal Reserve Bank, and/or other short-term investments; asset quality; well-capitalized position; and profitable operating results. Cyclical and other economic trends and conditions can disrupt our desired liquidity position at any time. We expect that these conditions would generally be of a short-term nature. Under such circumstances, we expect

90

Table of Contents

our reverse repurchase agreements and federal funds sold positions, or balances at the Federal Reserve Bank, if any, to serve as the primary source of immediate liquidity. At December 31, 2021, we had total federal funds credit lines of $300.0 million with no outstanding advances. If we needed additional liquidity, we would turn to short-term borrowings as an alternative immediate funding source and would consider other appropriate actions such as promotions to increase core deposits or the use of the brokered deposit markets. At December 31, 2021, we had $981.1 million of credit available at the Federal Reserve Bank’s discount window, but had no outstanding advances as of the end of 2021. In addition, we could draw on additional alternative immediate funding sources from lines of credit extended to us from our correspondent banks and/or the FHLB. At December 31, 2021, we had a total FHLB credit facility of $2.8 billion with $12.1 million in outstanding FHLB letters of credit to secure certain public funds deposits, leaving $2.8 billion in availability on the FHLB credit facility. We have a $100.0 million unsecured line of credit with U.S. Bank National Association with no outstanding advances. We believe that our liquidity position continues to be adequate and readily available.

Our contingency funding plan describes several potential stages based on stressed liquidity levels. Liquidity key risk indicators are reported to the Board of Directors on a quarterly basis. During 2021, we conducted contingency funding plan stress tests on a quarterly basis. We maintain various wholesale sources of funding. If our deposit retention efforts were to be unsuccessful, we would utilize these alternative sources of funding. Under such circumstances, depending on the external source of funds, our interest cost would vary based on the range of interest rates charged. This could increase our cost of funds, impacting our net interest margin and net interest spread.

Asset-Liability Management and Market Risk Sensitivity

Our earnings and the economic value of equity vary in relation to the behavior of interest rates and the accompanying fluctuations in market prices of certain of our financial instruments. We define interest rate risk as the risk to earnings and equity arising from the behavior of interest rates. These behaviors include increases and decreases in interest rates as well as continuation of the current interest rate environment.

Our interest rate risk principally consists of reprice, option, basis, and yield curve risk. Reprice risk results from differences in the maturity or repricing characteristics of asset and liability portfolios. Option risk arises from embedded options in the investment and loan portfolios such as investment securities calls and loan prepayment options. Option risk also exists since deposit customers may withdraw funds at their discretion in response to general market conditions, competitive alternatives to existing accounts or other factors. The exercise of such options may result in higher costs or lower revenue. Basis risk refers to the potential for changes in the underlying relationship between market rates or indices, which subsequently result in narrowing spreads on interest-earning assets and interest-bearing liabilities. Basis risk also exists in administered rate liabilities, such as interest-bearing checking accounts, savings accounts, and money market accounts where the price sensitivity of such products may vary relative to general markets rates. Yield curve risk adverse consequences of nonparallel shifts in the yield curves of various market indices that impact our assets and liabilities.

We use simulation analysis as a primary method to assess earnings at risk and equity at risk due to assumed changes in interest rates. Management uses the results of its various simulation analyses in combination with other data and observations to formulate strategies designed to maintain interest rate risk within risk tolerances.

Simulation analysis involves the use of several assumptions including, but not limited to, the timing of cash flows such as the terms of contractual agreements, investment security calls, loan prepayment speeds, deposit attrition rates, the interest rate sensitivity of loans and deposits relative to general market rates, and the behavior of interest rates and spreads. Equity at risk simulation uses assumptions regarding discount rates that value cash flows. Simulation analysis is highly dependent on model assumptions that may vary from actual outcomes. Key simulation assumptions are subject to stress testing to assess the impact of assumption changes on earnings at risk and equity at risk. Model assumptions are reviewed by our Assumptions Committee.

Earnings at risk is defined as the percentage change in net interest income due to assumed changes in interest rates. Earnings at risk is generally used to assess interest rate risk over relatively short time horizons.

Equity at risk is defined as the percentage change in the net economic value of assets and liabilities due to changes in interest rates compared to a base net economic value. The discounted present value of all cash flows

91

Table of Contents

represents our economic value of equity. Equity at risk is generally considered a measure of the long-term interest rate exposures of the balance sheet at a point in time.

The earnings simulation models take into account our contractual agreements with regard to investments, loans, deposits, borrowings, and derivatives as well as a number of behavioral assumptions applied to certain assets and liabilities.

Mortgage banking derivatives used in the ordinary course of business consist of forward sales contracts and interest rate lock commitments on residential mortgage loans. These derivatives involve underlying items, such as interest rates, and are designed to mitigate risk. Derivatives are also used to hedge mortgage servicing rights. For additional information see Note 28—Derivative Financial Instruments in the consolidated financial statements.

From time to time, we execute interest rate swaps to hedge some of our interest rate risks. Under these arrangements, the Company enters into a variable rate loan with a client in addition to a swap agreement. The swap agreement effectively converts the client’s variable rate loan into a fixed rate loan. The Company then enters into a matching swap agreement with a third-party dealer to offset its exposure on the customer swap. The Company may also execute interest rate swap agreements that are not specific to client loans. As of December 31, 2021, the Company did not have such agreements. For additional information on these derivatives refer to Note 28—Derivative Financial Instruments in the consolidated financial statements.

Our interest rate risk key indicators are applied to a static balance sheet using forward rates from the Moody’s Baseline Scenario. This Base Case Scenario assumes the maturity composition of asset and liability rollover volumes is modeled to approximately replicate current consolidated balance sheet characteristics throughout the simulation. These treatments are consistent with the Company’s goal of assessing current interest rate risk embedded in its current balance sheet. The Base Case Scenario assumes that maturing or repricing assets and liabilities are replaced at current market prices consistent with maintaining a stable balance sheet. Key rate drivers are used to price assets and liabilities with sensitivity assumptions used to price non-maturity deposits. The sensitivity assumptions for the pricing of non-maturity deposits are subjected to stress testing no less frequently than on an annual basis.

Interest rate shocks are applied to the Base Case on an instantaneous basis. The range of interest rate shocks will include upward and downward movements of rates through 400 basis points in 100 basis point increments. At times, market conditions may result in assumed rate movements that will be deemphasized. For example, during a period of ultra-low interest rates, certain downward rate shocks may be impractical. The Model simulation results produced from the Base Case Scenario and related instantaneous shocks for changes in net interest income and instantaneous rate shocks for changes in the economic value of equity are referred to as the Core Scenario Analysis and constitute the policy key risk indicators for interest rate risk when compared to risk tolerances.

As of December 31, 2021, the earnings simulations indicated that the impact of an instantaneous 100 basis point increase / decrease in rates would result in an estimated 9.41% increase (up 100) and 7.58% decrease (down 100) in net interest income.

We use Economic Value of Equity (“EVE”) analysis as an indicator of the extent to which the present value of our capital could change, given potential changes in interest rates. This measure also assumes a static balance sheet (Base Case Scenario) with rate shocks applied as described above. At December 31, 2021, the percentage change in EVE due to a 100 basis point increase or decrease in interest rates was 3.61% and (4.12)%, respectively. The percentage change in EVE due to a 200 basis point increase in interest rates was 6.37%.

Simulation analysis involves the use of several assumptions including, but not limited to, the timing of cash flows such as investment security calls, loan prepayment speeds, deposit attrition rates, the interest rate sensitivity of loans and deposits relative to general market rates, and the behavior of interest rates and spreads. Furthermore, equity at risk simulation uses assumptions regarding discount rates that value cash flows. Simulation analysis is highly dependent on model assumptions that may vary from actual outcomes. For example, higher levels of interest rate sensitivity of deposits to upward movements in interest rates may adversely impact net interest income. Additionally, slower prepayment speeds of loans may adversely impact the economic value of equity in a rising interest rate environment. Key simulation assumptions are subject to stress testing to assess the impact of assumption changes on earnings at risk and equity at risk.

The analysis provided below assumes the base case the Moody’s Baseline forecast as described above. Parallel and sustained interest rate shocks are applied over a one-year time horizon on an instantaneous and ramped basis. Instantaneous shocks assume immediate, sustained interest rate shocks, whereas ramped shocks distribute the assumed change in rates attributable to the shock evenly across the one-year time horizon. This analysis is applied to a static balance sheet that assumes maturing or repricing assets and liabilities are replaced at current market prices and volumes consistent with maintaining a stable balance sheet, with the exception of PPP loans that are not assumed to be replaced. The downward rate shock is subject to product floors and a zero-interest rate.

LIBOR Transition

In July 2017, the Financial Conduct Authority (FCA), which regulates LIBOR, announced that it intends to stop

persuading or compelling banks to submit rates for the calculation of LIBOR at the end of 2021. On March 5, 2021, the FCA confirmed that all LIBOR settings will either cease to be provided by any administrator or no longer be representative immediately after December 31, 2021 for the one-week and two-month US dollar settings and immediately after June 30, 2023 for all remaining US dollar settings.

​

The Alternative Reference Rates Committee has proposed Secured Overnight Financing Rate (“SOFR”) as its preferred rate as an alternative to LIBOR and has proposed a paced market transition plan to SOFR from LIBOR. Organizations are currently working on industry-wide and company-specific transition plans related to derivatives and cash markets exposed to LIBOR. As noted within Part I - Item 1A. Risk Factors of the this Form 10-K for the year ended 2021, we hold instruments that may be impacted by the discontinuance of LIBOR including floating rate obligations, loans, deposits, derivatives and hedges, and other financial instruments but is not able to currently predict the associated financial impact of the transition to an alternative reference rate.

​

We have established a cross-functional LIBOR transition working group that has 1) assessed the Company's current exposure to LIBOR indexed instruments and the data, systems and processes that will be impacted; 2) established a detailed implementation plan; and 3) developed a formal governance structure for the transition. The Company is in the process of developing and implementing various proactive steps to facilitate the transition on behalf of customers, which include:

| ● | The adoption and ongoing implementation of fallback provisions that provide for the determination of replacement rates for LIBOR-linked financial products.

| ● | The adoption of new products linked to alternative reference rates, such as adjustable-rate mortgages, consistent with guidance provided by the U.S. regulators, the Alternative Reference Rates Committee, and GSEs.

| ● | The selection of SOFR indices as the replacement indices, and successful completion of systems testing using the SOFR replacement indices.

The Company discontinued quoting LIBOR on September 30, 2021 and discontinued originating new products linked to LIBOR on December 31, 2021.

​

The Company continues to evaluate its financial and operational infrastructure in its effort to transition all financial and strategic processes, systems, and models to reference rates other than LIBOR. The Company is in the

93

Table of Contents

process of developing and implementing processes to educate client-facing associates and coordinate communications with customers regarding the transition.

As of December 31, 2021, the Company had the following exposures to LIBOR:

| ● | Approximately $6.9 billion of total outstanding loans reference LIBOR. Of this amount, $6.3 billion have maturities occurring after the LIBOR discontinuation date of June 30, 2023.

| ● | Approximately $20.8 billion in interest rate swaps that are indexed to LIBOR with a gross positive fair value of $408.8 million and a gross negative fair value of $410.1 million. However, the interest rate swaps associated with this program do not meet the strict hedge accounting requirements. Therefore, the transition to LIBOR will have no hedge accounting impact as changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. Moreover, the exposure of both sides of these swaps are presented in these figures. These exposures are intended to offset each other.

| ● | Trust preferred securities that reference LIBOR and had a total principal balance of $118.6 million. These securities have maturities ranging from October 7, 2033 through March 14, 2037.

| ● | Subordinated debt that references LIBOR that had a principal balance of $13 million. This debt matures June 30, 2027 and has an initial call date of June 30, 2022.

Asset Credit Risk and Concentrations

The quality of our interest-earning assets is maintained through our management of certain concentrations of credit risk. We review each individual earning asset including investment securities and loans for credit risk. To facilitate this review, we have established credit and investment policies that include credit limits, documentation, periodic examination, and follow-up. In addition, we examine these portfolios for exposure to concentration in any one industry, government agency, or geographic location.

Loan and Deposit Concentration

We have no material concentration of deposits from any single customer or group of customers. We have no significant portion of our loans concentrated within a single industry or group of related industries. Furthermore, we attempt to avoid making loans that, in an aggregate amount, exceed 10% of total loans to a multiple number of borrowers engaged in similar business activities. At December 31, 2021 and 2020, there were no aggregated loan concentrations of this type. We do not believe there are any material seasonal factors that would have a material adverse effect on us. We do not have material foreign loans or deposits.

Concentration of Credit Risk

Each category of earning assets has a certain degree of credit risk. We use various techniques to measure credit risk. Credit risk in the investment portfolio can be measured through bond ratings published by independent agencies. In the investment securities portfolio, the investments consist of U.S. government-sponsored entity securities, tax-free securities, or other securities having ratings of “AAA” to “Not Rated”. All securities, with the exception of those that are not rated, were rated by at least one of the nationally recognized statistical rating organizations. The credit risk of the loan portfolio can be measured by historical experience. We maintain our loan portfolio in accordance with credit policies that we have established. Although the subsidiary has a diversified loan portfolio, a substantial portion of their borrowers’ abilities to honor their contracts is dependent upon economic conditions within our geographic footprint and the surrounding regions.

We consider concentrations of credit to exist when, pursuant to regulatory guidelines, the amounts loaned to a multiple number of borrowers engaged in similar business activities which would cause them to be similarly impacted by general economic conditions represents 25% of Tier 1 capital plus regulatory adjusted allowance for credit losses of the Company, or $860.6 million at December 31, 2021. Based on this criteria, we had seven such credit concentrations at December 31, 2021, including loans on hotels and motels of $892.6 million, loans to lessors of nonresidential buildings (except mini-warehouses) of $4.7 billion, loans secured by owner occupied office buildings (including medical office buildings) of $1.8 billion, loans secured by owner occupied nonresidential buildings (excluding office buildings) of $1.7 billion, loans to lessors of residential buildings (investment properties and multi-family) of $1.3 billion, loans secured by

1st mortgage 1-4 family owner occupied residential property (including condos and home equity lines) of $4.1 billion and loans secured by jumbo (original loans greater than $548,250) 1st mortgage 1-4 family owner occupied residential property of $1.6 billion. The risk for these loans and for all loans is managed collectively through the use of credit underwriting practices developed and updated over time. The loss estimate for these loans is determined using our standard ACL methodology.

With some financial institutions adopting CECL in the first quarter of 2020, banking regulators established new guidelines for calculating credit concentrations. Banking regulators set the guidelines for construction, land development and other land loans to total less than 100% of total Tier 1 capital less modified CECL transitional amount plus ACL (CDL concentration ratio) and for total commercial real estate loans (construction, land development and other land loans along with other non-owner occupied commercial real estate and multifamily loans) to total less than 300% of total Tier 1 capital less modified CECL transitional amount plus ACL (CRE concentration ratio). Both ratios are calculated by dividing certain types of loan balances for each of the two categories by the Bank’s total Tier 1 capital less modified CECL transitional amount plus ACL. At December 31, 2021, the Bank’s CDL concentration ratio was 55.2% and its CRE concentration ratio was 238.5%. At December 31, 2020, the Bank’s CDL concentration ratio was 54.1% and its CRE concentration ratio was 229.5%. As of December 31, 2021 and 2020, the Bank was below the established regulatory guidelines. When a bank’s ratios are in excess of one or both of these loan concentration ratios guidelines, banking regulators generally require an increased level of monitoring in these lending areas by bank Management. Therefore, we monitor these two ratios as part of our concentration management processes.

Effect of Inflation and Changing Prices

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which require the measure of financial position and results of operations in terms of historical dollars, without consideration of changes in the relative purchasing power over time due to inflation. Unlike most other industries, the majority of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant effect on a financial institution’s performance than does the effect of inflation. Interest rates do not necessarily change in the same magnitude as the prices of goods and services.

While the effect of inflation on banks is normally not as significant as is its influence on those businesses which have large investments in plant and inventories, it does have an effect. During periods of high inflation, there are normally corresponding increases in money supply, and banks will normally experience above average growth in assets, loans and deposits. Also, general increases in the prices of goods and services will result in increased operating expenses. Inflation also affects our bank’s customers and may result in an indirect effect on our bank’s business.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of SouthState Corporation (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. Management has assessed the effectiveness of internal control over financial reporting using the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

​

The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

​

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

​

Based on the testing performed using the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), management of the Company believes that the Company’s internal control over financial reporting was effective as of December 31, 2021.

​

The effectiveness of our internal control over financial reporting as of December 31, 2021, has been audited by Dixon Hughes Goodman LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

Shareholders and the Board of Directors

SouthState Corporation

Opinion on Internal Control Over Financial Reporting

We have audited SouthState Corporation’s (the “Company”) internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, SouthState Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of SouthState Corporation as of December 31, 2021 and 2020, and for each of the three years in the period ended December 31, 2021, and our report dated February 25, 2022, expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying management’s report on internal control over financial reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

Shareholders and the Board of Directors

SouthState Corporation

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of SouthState Corporation and Subsidiaries (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020 and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2022 expressed an unqualified opinion thereon.

Adoption of New Accounting Standard

As discussed in Notes 1 and 6 to the consolidated financial statements, effective January 1, 2020, the Company changed its method of accounting for credit losses due to the adoption of Accounting Standards Codification Topic 326, Financial Instruments – Credit Losses.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Credit Losses

As of December 31, 2021, the Company’s loan portfolio was $23.9 billion and the associated allowance for credit losses (“ACL”) was $301.8 million. As described in Notes 1 and 6 to the consolidated financial statements, the Company’s ACL recorded in the balance sheet reflects management’s best estimate within the range of expected credit losses. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The ACL is measured on a collective pool basis when similar risk characteristics exist and the Discounted Cash Flow method is utilized for each loan in a pool, and the results are aggregated at the pool level. A periodic tendency to default and absolute loss given default are applied to a projective model of the loan’s cash flow while considering prepayment and principal curtailment effects. In determining the proper level of the ACL, Management determined that the loss experience of the Company provides the best basis for its assessment of expected credit losses. Management evaluates the appropriateness of the reasonable and supportable forecast scenarios and takes into consideration the scenarios in relation to actual economic and other data (such as COVID-19 epidemiological data and federal stimulus), as well as the volatility and magnitude of changes within those scenarios quarter over quarter, and consideration of condition within the bank’s operating environment and geographic area. Included in the Company’s methodology to determine its ACL, management considers the need to qualitatively adjust expected credit losses for information not already captured in the loss estimation process. These qualitative adjustments either increase or decrease the quantitative model estimation. Each period the Company considers qualitative factors that are relevant within the qualitative framework.

We identified the Company’s estimate of the ACL as a critical audit matter. The principal considerations for that determination included the high degree of judgement and subjectivity relating to management’s selection and application of the macroeconomic data in the forecast and the identification and measurement of the qualitative factors. This required a high degree of auditor effort, including specialized skills and knowledge, and significant auditor judgment in evaluating the estimated credit losses for the loan portfolios.

The primary procedures we performed to address this critical audit matter included:

| ● | We obtained an understanding of the Company’s process for establishing the ACL, including the selection and application of macroeconomic data used in the forecasts and the basis for development and related adjustments of the qualitative factor components of the ACL. |

| ● | We evaluated the design and tested the operating effectiveness of controls relating to management’s determination of the ACL, including controls over: |

| o | Management’s process for selection of macroeconomic data used in the forecasts and the basis for development of qualitative factors of the ACL. |

| o | Management’s review of reliability and accuracy of data used to calculate and estimate the various components of the ACL, including accuracy of the calculation and validation procedures over the Models. |

| o | Management’s process to review the reasonableness of the forecasts and the qualitative factors, including any adjustments. |

| ● | We evaluated the reasonableness of management’s application of qualitative factors to the ACL, including the comparison of factors considered by management to third party or internal sources as well as evaluated the appropriateness and level of the qualitative factor adjustments. |

| ● | We evaluated the reasonableness of management’s selection of macroeconomic forecast weighting to the ACL, including the evaluation of data and information utilized by management by independently obtaining data and information to assess the appropriateness of the application of the macroeconomic factor weighting. |

| ● | We evaluated the mathematical accuracy of the ACL, including the mathematical application of the qualitative adjustments on the loan segments. |

| ● | We assessed the overall trends in credit quality, including adjustments for the qualitative factors by comparing the overall ACL to those recorded by the Company’s peer institutions. |

Note 1—Summary of Significant Accounting Policies

Nature of Operations

SouthState Corporation is a financial holding company headquartered in Winter Haven, Florida, and was incorporated under the laws of South Carolina in 1985. We provide a wide range of banking services and products to our customers through our Bank. The Bank operates SouthState Advisory, Inc., a wholly owned registered investment advisor. The Bank also operates Duncan-Williams, Inc. (“Duncan-Williams”), which it acquired on February 1, 2021. Duncan-Williams is a registered broker-dealer, headquartered in Memphis, Tennessee, that serves primarily institutional clients across the U.S. in the fixed income business. The Bank also owns CBI Holding Company, LLC (“CBI”), which in turn owns Corporate Billing, LLC (“Corporate Billing”), a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide. The holding company owns SSB Insurance Corp., a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code. R4ALL, Inc., the holding company’s subsidiary that managed a troubled loan purchased from the Bank, dissolved effective October 29, 2021. The Company also operates a correspondent banking division within the national bank subsidiary, of which the majority of its bond salesmen, traders and operational personnel are housed in facilities located in Birmingham, Alabama and Atlanta, Georgia. The Bank provides general banking services within a six (6) state footprint in Alabama, Florida, Georgia, North Carolina, South Carolina and Virginia..

The accounting and reporting policies of the Company and its consolidated subsidiary conform to accounting principles generally accepted in the United States of America (‘U.S. GAAP”). There are 13 unconsolidated subsidiaries of the Company that were established for the purpose of issuing in the aggregate approximately $118.6 million of trust preferred securities at December 31, 2021. During 2021, seven unconsolidated subsidiaries of the Company, approximately $39.9 million of trust preferred securities in the aggregate, were dissolved as the Company redeemed the trust preferred debt. See Note 11—Other Borrowings for further detailed descriptions of our trust preferred securities.

Unless otherwise mentioned or unless the context requires otherwise, references herein to "SouthState," the "Company" "we," "us," "our" or similar references mean SouthState Corporation and its consolidated subsidiaries. References to the “Bank” means SouthState Bank, National Association.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and other entities in which it has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Assets held by the Company in trust are not assets of the Company and are not included in the accompanying consolidated financial statements.

Segments

The Company, through its Bank subsidiary, provides a broad range of financial services to individuals and companies in South Carolina, North Carolina, Florida, Alabama, Georgia and Virginia. These services include demand, time and savings deposits; lending and credit card servicing; ATM processing; mortgage banking services; correspondent banking services and wealth management and trust services. While the Company’s decision makers monitor the revenue streams of the various financial products and services, operations are managed and financial performance is evaluated on an organization-wide basis. Accordingly, the Company’s banking and finance operations are not considered by management to constitute more than one reportable operating segment.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses for loans and investment securities held to maturity, fair value of financial instruments, fair values of assets

and liabilities acquired in business combinations, loss estimates related to loans and other real estate acquired, evaluating impairment of investment securities, goodwill impairment tests and valuation of deferred tax assets.

In connection with the determination of the allowance for credit losses, management has identified specific loans as well as adopted a policy of providing amounts for loan valuation purposes which are not identified with any specific loan but are derived from models based on macroeconomic factors and forecasts. Management believes that the allowance for credit losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic forecasts. In addition, regulatory agencies, as an integral part of the examination process, periodically review the banking subsidiary’s allowance for credit losses. Such agencies may require additions to the allowance based on their judgments about information available to them at the time of their examination.

Concentrations of Credit Risk

The Company’s Bank subsidiary grants agribusiness, commercial, and residential loans to customers throughout South Carolina, North Carolina, Florida, Alabama, Virginia and Georgia. Although the subsidiary has a diversified loan portfolio, a substantial portion of their borrowers’ abilities to honor their contracts is dependent upon economic conditions within South Carolina, North Carolina, Florida, Alabama, Virginia, Georgia and the surrounding regions.

The Company considers concentrations of credit to exist when, pursuant to regulatory guidelines, the amounts loaned to a multiple number of borrowers engaged in similar business activities which would cause them to be similarly impacted by general economic conditions represents 25% of total Tier 1 capital plus regulatory adjusted allowance for credit losses of the Company, or $860.6 million at December 31, 2021. Based on this criteria, we had seven such credit concentrations at December 31, 2021, including loans on hotels and motels of $892.6 million, loans to lessors of nonresidential buildings (except mini-warehouses) of $4.7 billion, loans secured by owner occupied office buildings (including medical office buildings) of $1.8 billion, loans secured by owner occupied nonresidential buildings (excluding office buildings) of $1.7 billion, loans to lessors of residential buildings (investment properties and multi-family) of $1.3 billion, loans secured by 1st mortgage 1-4 family owner occupied residential property (including condos and home equity lines) of $4.1 billion and loans secured by jumbo (original loans greater than $548,250) 1st mortgage 1-4 family owner occupied residential property of $1.6 billion. The risk for these loans and for all loans is managed collectively through the use of credit underwriting practices developed and updated over time. The loss estimate for these loans is determined using our standard ACL methodology.

Cash and Cash Equivalents

For the purpose of presentation in the consolidated statements of cash flows, cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from banks including restricted pledged cash, interest bearing deposits with banks, purchases of securities under agreements to resell, and federal funds sold. Due from bank balances are maintained at other financial institutions. Federal funds sold are generally purchased and sold for one-day periods, but may, from time to time, have longer terms.

The Company enters from time to time into purchases of securities under agreements to resell substantially identical securities. When the Company enters into such repurchase agreements, the securities purchased under agreements to resell generally consist of U.S. government-sponsored entities and agency mortgage-backed securities. The Company may elect to use other asset classes at its discretion. It is the Company’s practice to take possession of securities purchased under agreements to resell. The securities are delivered into the Company’s account maintained by a third-party custodian designated by the Company under a written custodial agreement that explicitly recognizes the Company’s interest in the securities. The Company monitors the market value of the underlying securities, including accrued interest, which collateralizes the related receivable on agreements to resell. Historically, these agreements were considered to be cash equivalents with maturities of three months or less. The Company held no securities under agreements to resell at December 31, 2021.

Trading Securities

Through its Correspondent Banking Department and its wholly owned broker dealer Duncan-Williams Inc., the Company purchases trading securities and subsequently sells them to their customers to take advantage of market

F-12

opportunities, when presented, for short-term revenue gains. Securities purchased for this portfolio are primarily municipals, treasuries and mortgage-backed agency securities and are held for short periods of time. This portfolio is carried at fair value and realized and unrealized gains and losses are included in trading securities revenue, a component of Correspondent Banking and Capital Market Income in our Consolidated Statements of Net Income.

Investment Securities

Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and carried at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as “available for sale” and carried at fair value with unrealized gains and losses excluded from earnings and reported in Other Comprehensive Income.

Purchase premiums and discounts are recognized in interest income using methods approximating the interest method over the terms of the securities. Gains and losses realized on sales of securities available for sale are determined using the specific identification method.

Management no longer evaluates securities for other-than-temporary impairment, otherwise referred to herein as Other Than Temporary Impairment (“OTTI”), as ASC Subtopic 326-30, Financial Instruments—Credit Losses—Available for sale Debt Securities, changes the accounting for recognizing impairment on available for sale debt securities. Each quarter Management evaluates impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value. Management considers the nature of the collateral, potential future changes in collateral values, default rates, delinquency rates, third-party guarantees, credit ratings, interest rate changes since purchase, volatility of the security’s fair value and historical loss information for financial assets secured with similar collateral among other factors. Credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby Management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the Provision for Credit Losses in the Consolidated Statements of Income. (see Note 3—Investment Securities).

Other investments include stock acquired for regulatory purposes, investments in unconsolidated subsidiaries and other nonmarketable investment securities. Stock acquired for regulatory purposes include Federal Home Loan Bank of Atlanta (“FHLB”) stock and Federal Reserve Bank (“FRB”) stock. These securities do not have a readily determinable fair value because their ownership is restricted and they lack a market for trading. As a result, these securities are carried at cost and are periodically evaluated for impairment. Investments in unconsolidated subsidiaries represent a minority investment in SCBT Capital Trust I, SCBT Capital Trust II, SCBT Capital Trust III, TSB Statutory Trust I, SAVB Capital Trust I, SAVB Capital Trust II, Southeastern Bank Financial Statutory Trust I, Southeastern Bank Financial Statutory Trust II, Provident Community Bancshares Capital Trust I, FCRV Statutory Trust I, Community Capital Statutory Trust I, CSBC Statutory Trust I, and Provident Community Bancshares Capital Trust II. These investments are recorded at cost and the Company receives quarterly dividend payments on these investments. Other nonmarketable investment securities consist of Business Development Corporation stock and stock in Banker’s Banks. These investments also do not have a readily determinable fair value because their ownership is restricted and they lack a market for trading. As a result, these securities are carried at cost and are periodically evaluated for impairment.

Loans Held for Sale

The Company sells residential mortgages to government sponsored entities (“GSEs “) and mortgage and third-party investors, who may issue securities backed by pools of such loans. The Company retains no beneficial interests in these sales, but may retain the servicing rights for the loans sold. The Company is obligated to subsequently repurchase a loan if the purchaser discovers a representation or warranty violation such as noncompliance with eligibility or servicing requirements, or customer fraud, that should have been identified in a loan file review. Mortgage loans held for sale are accounted for at fair value on an individual loan basis. Estimated fair value is determined on the basis of existing forward commitments, or the current market value of similar loans. Changes in the fair value, and realized gains and losses on the sales of mortgage loans, are reported in Mortgage Banking Income, a component of Noninterest Income in our Consolidated Statements of Income.

F-13

Table of Contents

Loans

Loans that Management has originated and has the intent and ability to hold for the foreseeable future or until maturity or pay off generally are reported at their unpaid principal balances, less unearned income and net of any deferred loan fees and costs. Unearned income on installment loans is recognized as income over the terms of the loans by methods that generally approximate the interest method. Interest on other loans is calculated by using the simple interest method on daily balances of the principal amount outstanding.

We place non acquired loans and acquired loans on nonaccrual once reasonable doubt exists about the collectability of all principal and interest due. Generally, this occurs when principal or interest is 90 days or more past due, unless the loan is well secured and in the process of collection.

A loan is evaluated individually for loss when it is on nonaccrual and has a net book balance over $1 million. Large pools of homogeneous loans are collectively evaluated for loss and reserved at the pool level. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as nonaccrual, provided that Management expects to collect all amounts due, including interest accrued at the contractual interest rate for the period of delay.

Troubled Debt Restructurings (“TDRs”)

The Bank measures expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals, or modifications, unless the Company reasonably expects it will execute a TDR with a borrower. In the event of a reasonably-expected TDR, the Company factors the reasonably-expected TDR into the current expected credit losses estimate. For consumer loans, the point at which a TDR is reasonably expected is when the Company approves the borrower’s application for a modification (i.e., the borrower qualifies for the TDR) or when the Credit Administration department approves loan concessions on substandard loans. For commercial loans, the point at which a TDR is reasonably expected is when the Company approves the loan for modification or when the Credit Administration department approves loan concessions on substandard loans. The Company uses a discounted cash flow methodology for a TDR to calculate the effect of the concession provided to the borrower within the allowance for credit losses.

A restructuring that results in only a delay in payments that is insignificant is not considered an economic concession. In accordance with the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, the Company implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. The Company’s payment relief assistance includes forbearance, deferrals, extension and re-aging programs, along with certain other modification strategies. The Company elected the accounting policy in the CARES Act to not apply TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic if the concession met the criteria as defined under the CARES Act.

Allowance for Credit Losses (“ACL”)

On January 1, 2020, we adopted the requirements of Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, sometimes referred to herein as ASU 2016-13. Topic 326 was subsequently amended by ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses; ASU No. 2019-05, Codification Improvements to Topic 326, Financial Instruments-Credit Losses; and ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. This standard applies to all financial assets measured at amortized cost and off balance sheet credit exposures, including loans, investment securities and unfunded commitments. We applied the standard’s provisions using the modified retrospective method as a cumulative-effect adjustment to retained earnings as of January 1, 2020. With this transition method, we did not have to restate comparative prior periods presented in the financial statements related to Topic 326, but will present comparative prior periods disclosures using the previous accounting guidance for the allowance for loan losses. This adoption method is considered a change in accounting principle requiring additional disclosure of the nature of and reason for the change, which is solely a result of the adoption of the required standard.

ACL – Investment Securities

Management uses a systematic methodology to determine its ACL for investment securities held to maturity. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the held to maturity portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may result in a range of expected credit losses. Management monitors the held to maturity portfolio to determine whether a valuation account will need to be recorded. As of December 31, 2021, the Company had $1.8 billion of held to maturity securities and no related valuation account. As of December 31, 2021, the held to maturity portfolio consisted of U.S. Government Agency, U.S. Government Agency Residential and Commercial Mortgage-backed securities, and Small Business Administration loan-backed securities. Management does not believe that a fair value below amortized cost is due to credit related factors.

Management no longer evaluates available for sale securities for other-than-temporary impairment, otherwise referred to herein as OTTI, as ASC Subtopic 326-30, Financial Instruments—Credit Losses—Available for sale Debt Securities, changes the accounting for recognizing impairment on available for sale debt securities. Each quarter Management evaluates impairment where there has been a decline in fair value below the amortized cost basis of an available for sale security to determine whether there is a credit loss associated with the decline in fair value. Management considers the nature of the collateral, potential future changes in collateral values, default rates, delinquency rates, third-party guarantees, credit ratings, interest rate changes since purchase, volatility of the security’s fair value and historical loss information for financial assets secured with similar collateral among other factors. Credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby Management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the provision for credit losses in the Statements of Income. Management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the investment securities and does not record an allowance for credit losses on accrued interest receivable. As of December 31, 2021 and December 31, 2020, the accrued interest receivables for investment securities recorded in Other Assets were $19.2 million and $13.1 million, respectively.

ACL – Loans

The ACL for loans held for investment reflects Management’s estimate of losses that will result from the inability of our borrowers to make required loan payments. The Company established the incremental increase in the ACL at adoption through equity and subsequent adjustments through a provision for or recovery of credit losses recorded to earnings. The Company records loans charged off against the ACL and subsequent recoveries, if any, increase the ACL when they are recognized.

Management uses systematic methodologies to determine its ACL for loans held for investment and certain off-balance-sheet credit exposures. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loan portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, Management’s process for determining expected credit losses may result in a range of expected credit losses. The Company’s ACL recorded in the balance sheet reflects Management’s best estimate within the range of expected credit losses. The Company recognizes in net income the amount needed to adjust the ACL for Management’s current estimate of expected credit losses. The Company’s ACL is calculated using collectively evaluated and individually evaluated loans.

The allowance for credit losses is measured on a collective pool basis when similar risk characteristics exist. Loans with similar risk characteristics are grouped into homogenous segments, or pools, for analysis. The Discounted Cash Flow (“DCF”) method is utilized for each loan in a pool, and the results are aggregated at the pool level. A periodic tendency to default and absolute loss given default are applied to a projective model of the loan’s cash flow while considering prepayment and principal curtailment effects. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information (e.g., maturity date, payment amount, interest rate, etc.) with top-down pool assumptions (e.g., default rates and prepayment speeds). The Company has identified the following portfolio segments: Owner-Occupied Commercial Real Estate, Non Owner-Occupied Commercial Real Estate, Multifamily, Municipal, Commercial and Industrial, Commercial Construction and Land Development, Residential

F-15

Table of Contents

Construction, Residential Senior Mortgage, Residential Junior Mortgage, Revolving Mortgage, and Consumer and Other.

In determining the proper level of the ACL, Management has determined that the loss experience of the Bank provides the best basis for its assessment of expected credit losses. It therefore utilized its own historical credit loss experience by each loan segment over an economic cycle, while excluding loss experience from certain acquired institutions (i.e., failed banks). For most of the segment models for collectively evaluated loans, the Company incorporated two or more macroeconomic drivers using a statistical regression modeling methodology.

Management considers forward-looking information in estimating expected credit losses. The Company subscribes to a third-party service which provides a quarterly macroeconomic baseline outlook and alternative scenarios for the United States economy. The baseline, along with the evaluation of alternative scenarios, is used by Management to determine the best estimate within the range of expected credit losses. Management has evaluated the appropriateness of the reasonable and supportable forecast scenarios and has made adjustments as needed. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to the long term mean of historical factors within four quarters using a straight-line approach. The Company generally utilizes a four-quarter forecast and a four-quarter reversion period.

Included in its systematic methodology to determine its ACL, Management considers the need to qualitatively adjust expected credit losses for information not already captured in the loss estimation process. These qualitative adjustments either increase or decrease the quantitative model estimation (i.e., formulaic model results). Each period the Company considers qualitative factors that are relevant within the qualitative framework that includes the following: 1) Lending Policy; 2) Economic conditions not captured in models; 3) Volume and Mix of Loan Portfolio; 4) Past Due Trends; 5) Concentration Risk; 6) External Factors; and 7) Model Limitations.

When a loan no longer shares similar risk characteristics with its segment, the asset is assessed to determine whether it should be included in another pool or should be individually evaluated. The Company’s threshold for individually-evaluated loans includes all non-accrual loans with a net book balance in excess of $1.0 million. Management will monitor the credit environment and make adjustments to this threshold in the future if warranted. Based on the threshold above, consumer financial assets will generally remain in pools unless they meet the dollar threshold. The expected credit losses on individually-evaluated loans will be estimated based on discounted cash flow analysis unless the loan meets the criteria for use of the fair value of collateral, either by virtue of an expected foreclosure or through meeting the definition of collateral-dependent. Financial assets that have been individually evaluated can be returned to a pool for purposes of estimating the expected credit loss insofar as their credit profile improves and that the repayment terms were not considered to be unique to the asset.

Management measures expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals, or modifications, unless the Company reasonably expects it will execute a TDR with a borrower. In the event of a reasonably-expected TDR, the Company factors the reasonably-expected TDR into the current expected credit losses estimate. For consumer loans, the point at which a TDR is reasonably expected is when the Company approves the borrower’s application for a modification (i.e., the borrower qualifies for the TDR) or when the Credit Administration department approves loan concessions on substandard loans. For commercial loans, the point at which a TDR is reasonably expected is when the Company approves the loan for modification or when the Credit Administration department approves loan concessions on substandard loans. The Company uses a discounted cash flow methodology for a TDR to calculate the effect of the concession provided to the borrower within the ACL.

A restructuring that results in only a delay in payments that is insignificant is not considered an economic concession. In accordance with the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, the Company implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. The Company’s payment relief assistance includes forbearance, deferrals, extension and re-aging programs, along with certain other modification strategies. The Company elected the accounting policy in the CARES Act to not apply TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic if the concession met the criteria as defined under the CARES Act.

For purchased credit-deteriorated, otherwise referred to herein as PCD, assets are defined as acquired individual financial assets (or acquired groups of financial assets with similar risk characteristics) that, as of the date of acquisition,

F-16

Table of Contents

have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by the Company’s assessment. The Company records acquired PCD loans by adding the expected credit losses (i.e., allowance for credit losses) to the purchase price of the financial assets rather than recording through the provision for credit losses in the income statement. The expected credit loss, as of the acquisition day, of a PCD loan is added to the allowance for credit losses. The non-credit discount or premium is the difference between the unpaid principal balance and the amortized cost basis as of the acquisition date. Subsequent to the acquisition date, the change in the ACL on PCD loans is recognized through the Provision for Credit Losses in the Consolidated Statements of Income. The non-credit discount or premium is accreted or amortized, respectively, into interest income over the remaining life of the PCD loan on a level-yield basis. In accordance with the transition requirements within the standard, the Company’s acquired credit-impaired loans (i.e., ACI or Purchased Credit Impaired) were treated as PCD loans.

The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Therefore, Management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the portfolio and does not record an allowance for credit losses on accrued interest receivable. As of December 31, 2021 and December 31, 2020, the accrued interest receivables for loans recorded in Other Assets were $70.6 million and $93.9 million, respectively.

The Company has a variety of assets that have a component that qualifies as an off-balance sheet exposure. These primarily include undrawn portions of revolving lines of credit and standby letters of credit. The expected losses associated with these exposures within the unfunded portion of the expected credit loss will be recorded as a liability on the balance sheet. Management has determined that a majority of the Company’s off-balance-sheet credit exposures are not unconditionally cancellable. Management completes funding studies based on historical data to estimate the percentage of unfunded loan commitments that will ultimately be funded to calculate the reserve for unfunded commitments. Management applies this funding rate, along with the loss factor rate determined for each pooled loan segment, to unfunded loan commitments, excluding unconditionally cancellable exposures and letters of credit, to arrive at the reserve for unfunded loan commitments. As of December 31, 2021 and December 31, 2020, the liability recorded for expected credit losses on unfunded commitments was $30.5 million and $43.4 million, respectively. The current adjustment to the ACL for unfunded commitments is recognized through the Provision for Credit Losses in the Consolidated Statements of Income.

Other Real Estate Owned and Bank Property Held For Sale

Other real estate owned (“OREO”) consists of properties obtained through foreclosure or through a deed in lieu of foreclosure in satisfaction of loans. Prior to the merger with CSFL, the Company classified former branch sites as held for sale OREO. During the second quarter of 2020 and with the merger with CSFL, the Company elected to reclassify these assets as bank property held for sale and report on a separate line on the Consolidated Balance Sheet. Both OREO and bank property held for sale are recorded at the lower of cost or fair value and the fair value was determined on the basis of current valuations obtained principally from independent sources, adjusted for estimated selling costs. At the time of foreclosure or initial possession of collateral, for OREO, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the ACL. At the time a bank property is no longer in service and is moved to held for sale, any excess of the current book value over fair value is recorded as an expense in the Consolidated Statements of Income. Subsequent adjustments to this value are described in the following paragraph.

The Company reports subsequent declines in the fair value of OREO and bank properties held for sale below the new cost basis through valuation adjustments. Significant judgments and complex estimates are required in estimating the fair value of these properties, and the period of time within which such estimates can be considered current is significantly shortened during periods of market volatility. In response to market conditions and other economic factors, Management may utilize liquidation sales as part of its problem asset disposition strategy. As a result of the significant judgments required in estimating fair value and the variables involved in different methods of disposition, the net proceeds realized from sales transactions could differ significantly from the current valuations used to determine the fair value of these properties. Management reviews the value of these properties periodically and adjusts the values as appropriate. Revenue and expenses from OREO operations as well as gains or losses on sales and any subsequent adjustments to the value are recorded as OREO Expense and Loan Related Expense, a component of Noninterest Expense in the Consolidated Statements of Income. Expenses related to bank property held for sale, as well as gains or losses on sales and any subsequent adjustments to the value, are recorded Other Expenses, a component of Noninterest Expense in the Consolidated Statements of Income.

B usiness Combinations and Method of Accounting for Loans Acquired

The Company accounts for its acquisitions under FASB ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. We adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020 which now requires us to record purchased financial assets with credit deterioration (PCD assets), defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD assets. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit losses (or recovery for credit losses) in subsequent periods as they arise. Any non-credit discount or premium resulting from acquiring a pool of purchased financial assets with credit deterioration shall be allocated to each individual asset. At the acquisition date, the initial allowance for credit losses determined on a collective basis shall be allocated to individual assets to appropriately allocate any non-credit discount or premium. The non-credit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted to interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date.

​

A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and non-credit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted to interest income using the effective yield method.

​

For further discussion of our loan accounting and acquisitions, see Note 2—Mergers and Acquisitions, Note 4—Loans and Note 5—Allowance for Credit Losses to the audited condensed consolidated financial statements.

​

Premises and Equipment

Land is carried at cost. Office equipment, furnishings, and buildings are carried at cost less accumulated depreciation computed principally on the declining-balance and straight-line methods over the estimated useful lives of the assets. Leasehold improvements are amortized on the straight-line method over the shorter of the estimated useful lives of the improvements or the terms of the related leases including lease renewals only when the Company is reasonably assured of the aggregate term of the lease. Additions to premises and equipment and major replacements are added to the accounts at cost. Maintenance and repairs and minor replacements are charged to expense when incurred. Gains and losses on routine dispositions are reflected in current operations.

Leases (Topic 842) and Method of Adoption

​

On January 1, 2019, we adopted the requirements of Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842). Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; ASU No. 2018-11, Targeted Improvements; and ASU No. 2019-01, Codification Improvements to Topic 842 Leases. The purpose of the update was to increase transparency and comparability between organizations that enter into lease agreements. The key difference between the previous guidance and the update is the recognition of a right-of-use asset (ROU) and lease liability on the statement of financial position for those leases previously classified as operating leases under the old guidance. ASC Topic 842 defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. In applying this standard, we reviewed our material contracts to determine if they included a lease by this new definition and did not identify any new leases. Our lease agreements in which ASC Topic 842 has been applied are primarily for real estate properties, including retail branch locations, operations and administration locations and stand-alone ATM locations. These leases have lease terms from greater than 12 months to leases with options of more than 24 years. Related to lease payment terms, some are fixed payments or based on a fixed annual increases while others are variable and the annual increases are based on market rates. The Company performed an analysis on equipment leases for the implementation of ASC Topic 842 and determined the number and dollar amount of our equipment leases was not material.

A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We chose the transition method of adoption provided by ASU 2018-11, Leases (Topic 842) – Targeted Improvements, where we initially apply the new lease standard at the effective date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption if applicable. Therefore, we applied this standard to all existing leases as of the adoption date of January 1, 2019, recording a ROU asset and a lease liability in an equal amount. We did not have a cumulative-effect adjustment to the opening balance of retained earnings. With this transition method, we did not have to restate comparative prior periods presented in the financial statements related to ASC Topic 842, but will present comparative prior periods disclosures using the previous accounting guidance for leases. This adoption method is considered a change in accounting principle requiring additional disclosure of the nature of and reason for the change, which is solely a result of the adoption of the required standard.

​

ASC Topic 842 provides a package of practical expedients in applying the lease standard that had to be chosen at the date of adoption. We chose to elect this package of practical expedients. With this election, we do not have to reassess whether any expired or existing contracts are or contain a lease, do not have to reassess the classification of any expired or existing leases, do not have to separate lease and non-lease components and can account for both as a single lease component, and do not have to reassess initial direct costs or cash incentives for any existing leases due to immateriality. In addition, we chose not to apply ASC Topic 842 to short-term leases (leases with terms of 12 months or less) and not to record an underlying ROU asset or lease liability based on the uncertainty around the renewal of these leases. The Company will recognize lease expense for such leases on a straight-line basis over the lease term.

​

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We determined that we do not have any leases classified as finance leases and that all of our leases are operating leases at adoption. Two finance leases were acquired through the merger with CSFL, though these leases are immaterial. ROU assets and liabilities for operating leases are recognized at commencement date based on present value of lease payments not yet paid, discounted using the discount rate for the lease at the lease commencement date over the lease term. For operating leases, lease expense is determined by the sum of the lease payments to be recognized on a straight-line basis over the lease term. Based on the transition method that we chose to follow, the commencement date of the lease term for all existing leases is January 1, 2019. The lease term used for the calculation of the initial ROU asset and lease liability will include the initial lease term in addition to any renewal options or termination costs in the lease that we think are reasonably certain to be exercised or incurred. We received input from several levels of Management and our Corporate Real Estate Department in determining which options were reasonably certain to be exercised. A discount rate is also needed in the calculation of the initial ROU assets and lease liability. ASC Topic 842 requires that the implicit rate within the lease agreement be used if available. If not available, we should use its incremental borrowing rate in effect at the time of the lease commencement date. We looked at the incremental borrowing rate from several of our borrowing sources to determine an average rate to be used in the calculation of the initial ROU asset and lease liability. The Company also considered the term of the borrowings as they relate to the terms of the leases.

​

The adoption of the new standard had a material impact on our consolidated balance sheet, with the recording of ROU asset and lease liability of $82.2 million at the commencement date of January 1, 2019. We did not have a cumulative-effect adjustment to the opening balance of retained earnings at commencement. As of December 31, 2021 and 2020, we had ROU assets of $110.3 million and $113.4 million, respectively, recorded within premises and equipment on the balance sheet and a lease liability of $115.9 million and $118.3 million, respectively, recorded within other liabilities on the balance sheet. The adoption of ASC Topic 842 did not have a material impact on our consolidated income statement.

Bank Owned Life Insurance

Bank owned life insurance (BOLI) are comprised of long-term life insurance contracts on the lives of certain current and past employees where the insurance policy benefits and ownership are retained by the employer. Its cash surrender value is an asset that the Company uses to partially offset the future cost of employee benefits. The cash value accumulation on BOLI is permanently tax deferred if the policy is held to the insured person’s death and certain other conditions are met.

Intangible Assets

Intangible assets consist of goodwill, core deposit intangibles and client list intangibles that result from the acquisition of other banks or branches from other financial institutions. Core deposit intangibles represent the value of long-term deposit relationships acquired in these transactions. Client list intangibles represent the value of long-term client relationships for the wealth and trust management business. Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed in a business combination. At December 31, 2021 and December 31, 2020, the balance of goodwill was $1.6 billion. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value.

In January 2017, the FASB issued ASU No. 2017-04, which simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on Step 1 of the previous accounting guidance’s two-step impairment test under ASC Topic 350. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The new standard eliminates the requirement to calculate a goodwill impairment charge using Step 2 which involved calculating an implied fair value of goodwill for each reporting unit for which the first step indicated impairment. The standard does not change the guidance on completing Step 1 of the goodwill impairment test. An entity will still be able to perform today’s optional qualitative goodwill impairment assessment before determining whether to proceed to the quantitative step of determining whether the reporting unit’s carrying amount exceeds it fair value. This guidance was effective for the Company as of January 1, 2020.

​

The Company evaluated the carrying value of goodwill as of October 31, 2021, our annual test date, considering the effects of COVID-19 and other market condition and determined that no impairment charge was necessary.

​

Core deposit intangibles and client list intangibles consist primarily of amortizing assets established during the acquisition of other banks. This includes whole bank acquisitions and the acquisition of certain assets and liabilities from other financial institutions. Core deposit intangibles, included in Core Deposit and Other Intangibles in the Consolidated Balance Sheets, are amortized over the estimated useful lives of the deposit accounts acquired (generally 10 to 13 years) on either (1) the straight-line method or (2) an accelerated basis method which reasonably approximates the anticipated benefit stream from the accounts. The estimated useful lives are periodically reviewed for reasonableness. Client list intangibles, included in Core Deposit and Other Intangibles in the consolidated Balance Sheets, are amortized over the estimated useful lives of the client lists acquired (generally 15 years) on the straight-line method. The estimated useful lives are periodically reviewed for reasonableness.

Mortgage Servicing Rights

The Company has a mortgage loan servicing portfolio with related mortgage servicing rights. Mortgage servicing rights (“MSRs”) represent the present value of the future net servicing fees from servicing mortgage loans. Servicing assets and servicing liabilities must be initially measured at fair value, if practicable. For subsequent measurements, an entity can choose to measure servicing assets and liabilities either based on fair value or lower of cost or market. The Company uses the fair value measurement option for MSRs.

The methodology used to determine the fair value of MSRs is subjective and requires the development of a number of assumptions, including anticipated prepayments of loan principal. Fair value is determined by estimating the present value of the asset’s future cash flows utilizing estimated market-based prepayment rates and discount rates, interest rates and other economic factors and assumptions validated through comparison to trade information, industry surveys and with the use of independent third-party appraisals. Risks inherent in the MSRs valuation include higher than expected prepayment rates and/or delayed receipt of cash flows. The value of MSRs is significantly affected by mortgage interest rates available in the marketplace, which influence mortgage loan prepayment speeds. In general, during periods of declining interest rates, the value of mortgage servicing rights declines due to increasing prepayments attributable to increased mortgage refinance activity. Conversely, during periods of rising interest rates, the value of servicing rights generally increases due to reduced refinance activity. MSRs are carried at fair value with changes in fair value recorded as a component of Mortgage Banking Income each period in the Consolidated Statements of Income. The Company also uses derivative instruments to mitigate the income statement effect of changes in fair value due to

F-20

changes in valuation inputs and assumptions of its MSRs.

Transfer of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over the transferred assets is deemed to be surrendered when: (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The Company reviews all sales of loans by evaluating specific terms in the sales documents and believes that the criteria discussed above to qualify for sales treatment have been met as loans have been transferred for cash and the notes and mortgages for all loans in each sale are endorsed and assigned to the transferee. As stated in the commitment document, the buyer has no recourse with these loans except in the case of fraud. In certain sales, mortgage servicing rights may be retained and in other programs potential loss exposure from the credit enhancement obligation may be retained, both of which are evaluated and appropriately measured at the date of sale.

​

The Company packages fixed rate conforming mortgage loans as securities to investors issued through Fannie Mae and Freddie Mac and sold to third-party investors or sells them to satisfy cash forward mandatory commitments to Fannie Mae and Freddie Mac. The Company records loan securitizations or cash forwards as a sale when the transferred loans are legally isolated from its creditors and the accounting criteria for a sale are met. Gains or losses recorded on loan securitizations and cash forwards depend in part on the net carrying amount of the loans sold, which is allocated between the loans sold and retained interests based on their relative fair values at the date of sale. The Company generally retains mortgage servicing rights on residential mortgage loans sold in the secondary market. Loans transferred to “held-for-sale” with the intention of disposal through a bulk loan sale will be sold with servicing released. Since quoted market prices are not typically available, the fair value of retained interests is estimated through the services of a third-party service provider to determine the net present value of expected future cash flows. Such models incorporate management’s best estimates of key variables, such as prepayment speeds and discount rates that would be used by market participants and are appropriate for the risks involved. Gains and losses incurred on loans sold to third-party investors are included in Mortgage Banking Income in the Consolidated Statements of Income.

​

Revenue from Contracts with Customers (Topic 606) and Method of Adoption

​

On January 1, 2018, we adopted the requirements of Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“ASU Topic 606”). The majority of our revenue is derived primarily from interest income from receivables (loans) and securities. Other revenues are derived from fees received in connection with deposit accounts, mortgage banking activities including gains from the sale of loans and loan origination fees, correspondent banking activities including revenue from the sale of fixed income securities and fees from hedging services, and trust and investment advisory services. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

​

The Company adopted ASU Topic 606 using the retrospective transition approach which requires restatement of prior periods. The Company selected this method even though there were no material changes in the timing of revenue recognition due to the fact that ASU Topic 606 requires us to report network costs associated with debit card and ATM transactions netted against the related fees from such transactions. Previously, such network costs were reported as a component of other noninterest expense. The Company restated prior periods for this reclassification. For years 2021, 2020 and 2019, gross interchange and debit card transaction fees totaled $38.3 million, $30.2 million and $24.5 million, respectively while related network costs totaled $20.3 million, $16.5 million and $11.9 million, respectively. On a net basis, the Company reported $18.0 million, $13.7 million and $12.6 million, respectively, as interchange and debit card transactions fees in the accompanying Consolidated Statements of Income as noninterest income for the years ended December 31, 2021, 2020, and 2019. This adoption method is considered a change in accounting principle requiring additional disclosure of the nature of and reason for the change, which is solely a result of the adoption of the required standard. When applying the retrospective approach under ASU Topic 606, the Company has elected, as a practical expedient, to apply the revenue standard only to contracts that are not completed as of January 1, 2018. A completed contract is considered to be a contract for which all (or substantially all) of the revenue was recognized in accordance with revenue guidance that was in effect before January 1, 2018. There were no uncompleted contracts as of January 1, 2018 for which application of the new standard required an adjustment to retained earnings.

​

The following disclosures related to ASU Topic 606 involve income derived from contracts with customers. Within the scope of ASU Topic 606, the Company maintains contracts to provide services, primarily for investment advisory and/or custody of assets. Through the Company’s wholly owned subsidiaries, the Bank, and SouthState Advisory, Inc., the Company contracts with its customers to perform IRA, Trust, and/or Custody and Agency advisory services. Total revenue recognized from these contracts with customers was $37.0 million, $29.4 million and $29.2 million for the years ended December 31, 2021, 2020 and 2019. The Bank contracts with its customers to perform deposit account services. Total revenue recognized from these contracts with customers is $107.3 million, $85.7 million and $76.4 million for the years ended December 31, 2021, 2020 and 2019. Due to the nature of our relationship with the customers that we provide services, we do not incur costs to obtain contracts and there are no material incremental costs to fulfill these contracts that should be capitalized.

​

Disaggregation of Revenue - The portfolio of services provided to the Company’s customers which generates revenue for which the revenue recognition standard applies consists of approximately 1.1 million active contracts at December 31, 2021. The Company has disaggregated revenue according to the timing of the transfer of service. Total revenue derived from contracts in which services are transferred at a point in time was $180.8 million, $182.8 million and $104.3 million for the years ended December 31, 2021, 2020 and 2019. Total revenue derived from contracts in which services are transferred over time was $19.9 million, $17.9 million and $19.0 million for the years ended December 31, 2021, 2020 and 2019. Revenue is recognized as the services are provided to the customers. Economic factors impacting the customers could affect the nature, amount, and timing of these cash flows, as unfavorable economic conditions could impair the customers’ ability to provide payment for services. This risk is mitigated as we generally deduct payments from customers’ accounts as services are rendered.

​

Contract Balances - The timing of revenue recognition, billings, and cash collections results in billed accounts receivable on our balance sheet. Most contracts call for payment by a charge or deduction to the respective customer account but there are some that require a receipt of payment from the customer. For fee per transaction contracts, the customers are billed as the transactions are processed. For hourly rate and monthly service contracts related to trust and some investment revenues, the customers are billed monthly (generally as a percentage basis point of the market value of the investment account). In some cases, specific to SouthState Advisory, Inc., customers are billed in advance for quarterly services to be performed based on the past quarter’s average account balance. These do create contract liabilities or deferred revenue, as the customers pay in advance for service. Neither the contract liabilities nor the accounts receivables balances are material to the Company’s balance sheet.

​

Performance Obligations - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASU Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The performance obligations for these contracts are satisfied as the service is provided to the customer (either over time or at a point in time). The payment terms of the contracts are typically based on a basis point percentage of the investment account market value, fee per hour of service, or fee for service incurred. There are no significant financing components in the contracts. Excluding deposit services revenues which are mostly billed at a point in time as a fee for services incurred, all other contracts within the scope of ASU Topic 606 contain variable consideration in that fees earned are derived from market values of accounts or from hours worked for services performed which determines the amount of consideration to which we are entitled. The variability is resolved when the hours are incurred or services are provided. The contracts do not include obligations for returns, refunds, or warranties. The contracts are specific to the amounts owed to the Company for services performed during a period should the contracts be terminated.

​

Significant Judgments - All of the contracts create performance obligations that are satisfied at a point in time excluding the contracts billed in advance through SouthState Advisory, Inc. and some immaterial deposit revenues. Revenue is recognized as services are billed to the customers. Variable consideration does exist for contracts related to our trust and investment services as revenues are based on market values and services performed. The Company has adopted the right-to-invoice practical expedient for trust management contracts through SouthState Bank which we contract with our customers to perform IRA, Trust, and/or Custody services.

Advertising Costs

The Company expenses advertising costs as they are incurred and advertising communication costs the first time the advertising takes place. The Company may establish accruals for anticipated advertising expenses within the

F-22

Table of Contents

course of a fiscal year.

Comprehensive Income

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as (1) unrealized gains and losses on available for sale securities (2) unrealized gains and losses on effective portions of derivative financial instruments accounted for as cash flow hedges and (3) net change in unrecognized amounts related to pension and post-retirement benefits, are reported as a separate component of the equity section of the balance sheet. Such items, along with net income, are components of total comprehensive income (see Consolidated Statements of Comprehensive Income on page F-8).

Employee Benefit Plans

The Company’s defined benefit pension and other post retirement plans are accounted for in accordance with FASB ASC 715, Compensation—Retirement Benefits, which requires the Company to recognize the funded status in its statement of financial position. See Note 17—Retirement Plans for information regarding the defined benefit pension plan and Note 18—Post-Retirement Benefits for information regarding our post-retirement benefit plans. The Company terminated its defined benefit pension plan in 2019. The expected costs of the post retirement benefit plans are being expensed over the period that employees provide service.

The Employee Stock Purchase Plan (“ESPP”) allows for a look-back option which establishes the purchase price as an amount based on the lesser of the stock’s market price at the grant date or its market price at the exercise (or purchase) date. For the shares issued in exchange for employee services under the plan, the Company accounts for the plan under the FASB ASC 718, Compensation—Stock Compensation, in which the fair value measurement method is used to estimate the fair value of the equity instruments, based on the share price and other measurement assumptions at the grant date. See Note 19—Share-Based Compensation for the amount the Company recognized as expense for the years ended December 31, 2021, 2020 and 2019.

Income Taxes

Income taxes are provided for the tax effects of the transactions reported in the accompanying consolidated financial statements and consist of taxes currently due plus deferred taxes related primarily to differences between the tax basis and financial statement basis of gains on acquisitions, loans, available for sale securities, allowance for credit losses, write downs of OREO properties, bank properties held for sale, accumulated depreciation, net operating loss carryforwards, accretion income, deferred compensation, intangible assets, mortgage servicing rights, and pension plan and post-retirement benefits. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the Provision for Income Taxes in the Consolidated Statements of Income.

The Company recognizes interest and penalties accrued relative to unrecognized tax benefits in its respective federal or state income tax accounts. As of December 31, 2021 and 2020, there were no material accruals for uncertain tax positions. The Company and its subsidiaries file a consolidated federal income tax return. Additionally, income tax returns are filed by the Company or its subsidiaries in the state of Alabama, California, Colorado, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Texas, New York, Virginia, and in the city of New York City. Generally, the Company’s federal and state income tax returns are no longer subject to examination by taxing authorities for years prior to 2018.

Earnings Per Share

Basic earnings per share (“EPS”) represents income available to common shareholders divided by the weighted-average number of shares outstanding during the year. Diluted earnings per share reflects additional shares that would have been outstanding if dilutive potential shares had been issued. Potential shares that may be issued by the Company relate solely to outstanding stock options, restricted stock and restricted stock units (non-vested shares and vested shares subject to a holding period), and warrants, and are determined using the treasury stock method. Under the treasury stock method, the number of incremental shares is determined by assuming the issuance of stock for the

F-23

Table of Contents

outstanding stock options, reduced by the number of shares assumed to be repurchased from the issuance proceeds, using the average market price for the year of the Company’s stock. Weighted-average shares for the basic and diluted EPS calculations have been reduced by the average number of unvested restricted shares.

Derivative Financial Instruments

The Company’s interest rate risk management strategy incorporates the use of a derivative financial instrument, specifically an interest rate swap, to essentially convert a portion of its variable-rate debt to a fixed rate. Cash flows related to variable-rate debt will fluctuate with changes in an underlying rate index. When effectively hedged, the increases or decreases in cash flows related to the variable-rate debt will generally be offset by changes in cash flows of the derivative instrument designated as a hedge. This strategy is referred to as a cash flow hedge. For derivatives designated as hedging exposure to variable cash flows of a forecasted transaction (cash flow hedge), the derivative’s entire gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. For derivatives that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

The Company also maintains loan swaps which are accounted for as a fair value hedge. This derivative protects the Company from interest rate risk caused by changes in the LIBOR curve in relation to a certain designated fixed rate loan. Fair value hedges convert the fixed rate to a floating rate (see Note 28—Derivative Financial Instruments). For discussion related to Reference Rate Reform, please refer to the caption “Issued But Not Yet Adopted Accounting Standards” within this Note 1—Summary of Significant Accounting Policies.

The Company’s risk management strategy for its mortgage banking activities incorporates derivative instruments used to hedge both the value of the mortgage servicing rights and the mortgage pipeline. These derivative instruments are not designated as hedges and are not speculative in nature. The derivative instruments that are used to hedge the value of the mortgage servicing rights include financial forwards, futures contracts, and options written and purchased. When-issued securities and mandatory cash forward trades are typically used to hedge the mortgage pipeline. These instruments derive their cash flows, and therefore their values, by reference to an underlying instrument, index or referenced interest rate.

The Company’s risk management strategy also incorporates the use of interest rate swap contracts that help in managing interest rate risk within the loan portfolio and foreign currency exchange. These derivatives are not designated as hedges and are not speculative, and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third-party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings (See Note 28—Derivative Financial Instruments).

By using derivative instruments, the Company is exposed to credit and market risk. If the counterparty fails to perform, credit risk is equal to the fair value gain in a derivative. When the fair value of a derivative contract is positive, this situation generally indicates that the counterparty is obligated to pay the Company, and, therefore, creates a repayment risk for the Company. When the fair value of a derivative contract is negative, the Company is obligated to pay the counterparty and, therefore, has no repayment risk. The Company minimizes the credit risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by the Company.

The Company’s derivative activities are monitored by its Asset-Liability Management Committee as part of that committee’s oversight of the Company’s asset/liability and treasury functions. The Company’s Asset-Liability Management Committee is responsible for implementing various hedging strategies that are developed through its analysis of data from financial simulation models and other internal and industry sources. The resulting hedging strategies are then incorporated into the overall interest-rate risk management process.

The Company recognizes the fair value of derivatives as assets or liabilities in the financial statements. The accounting for the changes in the fair value of a derivative depends on the intended use of the derivative instrument at inception. The change in fair value of the effective portion of cash flow hedges is accounted for in other comprehensive

F-24

Table of Contents

income rather than net income. Changes in fair value of derivative instruments that are not intended as a hedge are accounted for in the net income in the period of the change (see Note 28—Derivative Financial Instruments for further disclosure).

Reclassification

Certain amounts previously reported have been reclassified to conform to the current year’s presentation. Such reclassifications had no effect on net income and shareholders’ equity.

Subsequent Events

The Company has evaluated subsequent events for accounting and disclosure purposes through the date the financial statements are issued. See Note 31—Subsequent Events for further information.

Recent Accounting and Regulatory Pronouncements

Accounting Standards Adopted

In February 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-02, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section of Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842). This update adds the content of SEC Staff Accounting Bulletin (“SAB”) No. 119 to the FASB Codification. SAB No.119 provides interpretive guidance on methodologies and supporting documentation for measuring credit losses, with a focus on the documentation the staff would normally expect registrants engaged in lending transactions to prepare and maintain to support estimates of current expected credit losses for loan transactions. The ASU also updates the SEC section of the FASB Codification for the delay in the effective date of Topic 842 for public business entities that otherwise would not meet the definition of a public business entity except for a requirement to include its financial information in another entity’s filing with the SEC. The clarification related to SAB No. 119 was adopted in the first quarter of 2020 when ASU 2016-13 was adopted. See ASU 2016-13 below for overall effect of Topic 326 Financial Instruments-Credit Losses on our consolidated financial statements. The change in the effective date for ASU 2016-02 – Leases did not affect the Company in that we adopted the standard in 2019.

​

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying the amending existing guidance. Some of the simplification items included are 1) simplification for intraperiod tax allocations where entities will determine the tax effect of pre-tax income or loss from continuing operations without consideration of the tax effect of other items that are not included in continuing operations, 2) simplification for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year allowing an entity to record a benefit for year-to-date loss in excess of its forecasted loss, and 3) simplify the accounting for income taxes by requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax. This guidance is effective for interim and annual reporting periods beginning after December 15, 2020. Early adoption is permitted. The amendments related to franchise taxes that are partially based on income should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. All other amendments should be applied on a prospective basis. The Company adopted ASU No. 2019-12 but it did not have a material impact on our consolidated financial statements.

​

In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans (Subtopic 715-20). ASU 2018-14 amends ASC 715-20 to add, remove, and clarify disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public business entities, ASU 2018-14 is effective for fiscal years ending after December 15, 2020 and requires entities to apply the amendment on a retrospective basis. Early adoption is permitted. The Company adopted ASU No. 2018-14 but it did not have a material impact on our consolidated financial statements.

​

In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial

F-25

Table of Contents

Instruments-Credit Losses, Topic 815. This update, related to ASU 2016-01, clarifies certain aspects brought to the Account Standards Board attention by stakeholders related to these ASUs, but does not change the core principles of these standards. The areas of improvement clarified in this update are related to 1) expected recoveries for purchased financial assets with credit deterioration, 2) transition relief for troubled debt restructurings, 3) disclosures related to accrued interest receivables, 4) financial assets secured by collateral maintenance provisions and 5) conforming amendment to Subtopic 805-20. This clarification was adopted in the first quarter of 2020 when the overall standard was adopted. See ASU 2016-13 below for overall effect of Topic 326 Financial Instruments-Credit Losses on our consolidated financial statements.

​

In April 2019, the FASB issued ASU No. 2019-05, Targeted Transition Relief (Topic 326 – Financial Instruments-Credit Losses). This update provides entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments—Credit Losses— Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10 applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held to maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement—Overall, and 825-10. This update was adopted in the first quarter of 2020 when the overall standard was adopted. See ASU 2016-13 below for overall effect of Topic 326 Financial Instruments-Credit Losses on our consolidated financial statements.

​

In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. This update related to ASU 2016-01, ASU 2017-12 and ASU 2016-13 clarifies certain aspects brought to the Account Standards Board attention by stakeholders related to these ASUs, but does not change the core principles of these standards. The clarifications related to ASU 2016-01 and 2017-12 were adopted in the second quarter of 2019 and did not have a material impact on our consolidated financial statements. The clarifications related to ASU 2016-13 were adopted in the first quarter of 2020 when the overall standard was adopted. See ASU 2016-13 below for overall effect of Topic 326 Financial Instruments-Credit Losses on our consolidated financial statements.

​

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820). ASU 2018-13 removes, modifies, and adds certain disclosure requirements in ASC 820 related to Fair Value Measurement on the basis of the concepts in the FASB Concepts Statement Conceptual Framework for Financial Reporting — Chapter 8: Notes to Financial Statements. ASU 2018-13 was effective for all entities for fiscal years beginning after December 15, 2019, including interim periods therein. The ASU requires application of the prospective method of transition (for only the most recent interim or annual period presented in the initial fiscal year of adoption) to the new disclosure requirement additions. The ASU also requires prospective application to any modifications to disclosures made because of the change to the requirements for the narrative description of measurement uncertainty. The effects of all other amendments made by the ASU must be applied retrospectively to all periods presented. This update did not have a material impact on our consolidated financial statements.

​

In January 2017, the FASB issued ASU No. 2017-04, Intangible-Goodwill and other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test under ASC Topic 350 and eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test consists of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The guidance was effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those years. Based on effects of the COVID-19 pandemic on the economy and on our stock price, the Company evaluated its goodwill on a quarterly basis in 2020 per ASU 2017-04 and has reverted to an annual impairment test cycle. The most recent analysis as of October 31, 2021 determined there was no impairment of goodwill or other intangibles. The Company will continue to monitor if a triggering event occurs that requires goodwill to be evaluated before the nest annual impairment test date.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an ACL that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in earlier recognition of credit losses for loans, investment securities portfolio, and purchased financial assets with credit deterioration. See Note 1—Summary of Significant Account Policies – Allowance for Credit Losses for further discussion. We adopted the new standard as of January 1, 2020. This standard did not have a material impact on our investment securities portfolio at implementation. Related to the implementation of ASU 2016-13, the Company recorded additional ACL for loans of $54.4 million, deferred tax assets of $12.6 million, an additional reserve for unfunded commitments of $6.4 million and an adjustment to retained earnings of $44.8 million. See table below for impact of ASU 2016-13 on the Company’s consolidated balance sheet. See Note 1—Summary of Significant Accounting Policies for further discussion.

Issued But Not Yet Adopted Accounting Standards

In March 2020, FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848 – Facilitation of the Effects of Reference Rate Reform on Financial Reporting and subsequently expanded the scope of ASU No. 2020-04 with the issuance of ASU No. 2021-01. This update provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that will be discontinued. The amendments in this update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The main provisions for contract modifications include optional relief by allowing the modification as a continuation of the existing contract without additional analysis and other optional expedients regarding embedded features. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate that will be discontinued because of reference rate reform. The amendments in this update were effective for all entities as of March 12, 2020 and

F-27

Table of Contents

may be applied through December 31, 2022. An entity may elect to apply the amendments in this update to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. An entity may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected, the amendments in this update must be applied prospectively for all eligible contract modifications and hedging relationships.

​

The Company has established a LIBOR Committee and various subcommittees which have evaluated the impact of adopting and implementing ASU 2020-04 on the consolidated financial statements including the evaluation of all of its contracts, hedging relationships and other transactions that will be affected by reference rates that are being discontinued. The cross-functional LIBOR Committee and subcommittees have 1) assessed the Company's current exposure to LIBOR indexed instruments and the data, systems and processes that will be impacted; 2) established a detailed implementation plan; and 3) developed a formal governance structure for the transition. The Company is in the process of developing and implementing various proactive steps to facilitate the transition on behalf of customers, which include the adoption and ongoing implementation of fallback provisions that provide for the determination of replacement rates for LIBOR-linked financial products; the adoption of new products linked to alternative reference rates, such as adjustable-rate mortgages, consistent with guidance provided by the U.S. regulators, the Alternative Reference Rates Committee, and government sponsored entities; the cessation of quoting LIBOR and originating new products linked to LIBOR by December 31, 2021; and the selection of SOFR indices as the replacement indices, and successful completion of systems testing using the SOFR replacement indices.

​

As a result of the implementation plan, the Company discontinued quoting LIBOR on September 30, 2021 and discontinued originating new products linked to LIBOR on December 31, 2021. The Company continues to evaluate its financial and operational infrastructure in its effort to transition all financial and strategic processes, systems, and models to reference rates other than LIBOR. The Company is in the process of developing and implementing processes to educate all client-facing associates and coordinate communications with customers regarding the transition. In addition, the Company expects to adopt the LIBOR transition relief allowed under ASU No. 2020-04.

Note 2—Mergers and Acquisitions

CenterState Bank Corporation

​

On June 7, 2020, the Company acquired all of the outstanding common stock of CSFL, of Winter Haven, Florida, the bank holding company for CenterState Bank, N.A. (“CSB”), in a stock transaction. Pursuant to the Merger Agreement, (i) CSFL merged with and into the Company, with the Company continuing as the surviving corporation, and (ii) immediately following the merger, SouthState Bank, a South Carolina banking corporation and wholly owned bank subsidiary of the Company, merged with and into CSB, a national banking association and wholly owned bank subsidiary of CSFL, with CSB continuing as the surviving bank. In connection with the bank merger, CSB changed its name to “South State Bank, National Association”. CSFL common shareholders received 0.3001 shares of the Company’s common stock in exchange for each share of CSFL stock resulting in the Company issuing 37,271,069 shares of its common stock. In total, the purchase price for CSFL was $2.26 billion including the value of the conversion of CSFL’s outstanding warrants, stock options and restricted stock units totaling $10.3 million. During the fourth quarter 2020, the purchase price (consideration transferred) decreased by $5.2 million due to an update to the value for stock options assumed and converted in the merger from $15.5 million to $10.3 million. The stock options assumed reflect their intrinsic value based upon a Black Scholes valuation.

​

In the acquisition, the Company acquired $13.0 billion of loans, including PPP loans, at fair value, net of $239.5 million, or 1.82%, estimated discount, including a fair value adjustment of $29.8 million recorded during the third quarter, to the outstanding principal balance, representing 113.9% of the Company’s total loans at December 31, 2019. Of the total loans acquired, Management identified $3.1 billion that had more than insignificantly deteriorated since origination and were thus determined to be PCD loans.

​

In its assumption of the deposit liabilities, the Company believed the deposits assumed from the acquisition have an intangible value. The Company applied ASC Topic 805, which prescribes the accounting for goodwill and other intangible assets such as core deposit intangibles, in a business combination. The Company determined the estimated

F-28

Table of Contents

fair value of the core deposit intangible asset totaled $125.9 million, which will be amortized utilizing a sum-of-the-years’-digit method over an estimated economic life not to exceed ten years. In determining the valuation amount, deposits were analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships. During the third quarter 2020, the Company identified an additional intangible related to its correspondent banking business acquired in the CSFL merger of approximately $10.0 million. As a result of the various measurement period adjustments identified during 2020 and 2021, goodwill was reduced by $38.1 million to $562.4 million.

​

During the years ended December 31, 2021 and 2020, the Company incurred approximately $64.4 million and $83.0 million, respectively, of acquisition and branch consolidation costs related to this transaction. These acquisition costs are reported in merger and branch consolidation related expenses on the Company’s Consolidated Statements of Income.

​

The CSFL transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition date.

Explanation of fair value adjustments

(a)— Represents the reversal of CSFL's existing fair value adjustments of $40.7 million and the adjustment to record securities at fair value (premium) totaling $46.2 million (includes reclassification of all securities held as HTM to AFS totaling $175.7 million).

(b)— Represents approximately 2.04%, or $269.1 million, total mark of the loan portfolio including a 1.97%, or $259.7 million credit mark, based on a third-party valuation. Also, includes the reversal of CSFL's ending allowance for credit losses of $158.2 million and fair value adjustments of $62.6 million. Fair value was subsequently adjusted by $29.8 million due to a reduction in the loan mark (discount).

(c)— Represents the MTM adjustment of $4.0 million on leased assets partially offset by the write-off of de minimis fixed assets of $1.6 million. Subsequently, the fair value on certain bank premises was adjusted by $2.9 million based on updated appraisals received.

(d)— Represents approximately a 1.28% core deposit intangible, or $125.9 million from a third-party valuation. This amount is net of $84.9 million existing core deposit intangible and $1.2 billion of existing goodwill from CSFL’s prior transactions that was reversed. Approximately $10.0 million in a customer list intangible related to the correspondent banking business was subsequently identified and recorded in the third quarter of 2020.

(e)— Represents the reversal of prior valuation reserves of $878,000 and recorded new valuation reserves of $1.7 million on both OREO and other repossessed assets. The fair value was subsequently adjusted based on gains and losses recognized from sales of OREO and other repossessed assets.

| (f)— | Represents deferred tax assets related to fair value adjustments measured using an estimated tax rate of 22.0%. This includes an adjustment from the CSFL tax rate to our tax rate. The difference in tax rates relates to state income taxes. Additional deferred tax liability related to subsequent fair value adjustments identified and an updated estimated tax rate of 23.78% was approximately $7.8 million.

(g)— Represents a valuation reserve of bank property held for sale of $4.4 million, a fair value adjustment of a lease receivable of $116,000 and a fair value adjustment of interest receivable of $501,000. These amounts are offset by positive fair value adjustment for investment in low income housing of $3.3 million.

(h)— Represents estimated premium for fixed maturity time deposits of $20.2 million partially offset by the reversal of existing CSFL fair value adjustments related to time deposit marks from other merger transactions of $546,000.

| (i)— | Represents the recording of a discount of $12.5 million on TRUPs from a third-party valuation partially offset by the reversal of the existing CSFL discount on TRUPs and other debt of $5.1 million.

| (j)— | Represents the reversal of an existing $7.1 million unfunded commitment reserve at purchase date partially offset by a fair value adjustment to increase lease liabilities associated with leased facilities totaling $2.5 million. The discount rate applied to the bank owned life insurance split dollar liability was subsequently adjusted resulting in an increase in the other liability of $857,000.

| (k)— | The purchase price, or the fair value of total consideration transferred, decreased by $5.2 million to $2.9 million for stock options assumed and converted in the merger. The stock options assumed reflect their intrinsic value based upon a Black Sholes valuation.

Comparative and Pro Forma Financial Information for the CSFL Acquisition

Pro-forma data for the year ended December 31, 2020 listed in the table below presents pro-forma information as if the CSFL acquisition occurred at the beginning of 2020. These results combine the historical results of CSFL in the Company’s Consolidated Statements of Income and, while certain adjustments were made for the estimated impact of certain fair value adjustments and other acquisition-related activity, they are not indicative of what would have occurred had the acquisition taken place on January 1, 2020.

Merger-related costs of $83.0 million from the CSFL acquisition were incurred during 2020 and were excluded from pro forma information below. No adjustments have been made to reduce the impact of any OREO write downs, investment securities sold or repayment of borrowings recognized by CSFL in 2020. The Company recorded expenses related to systems conversions and other costs of integration during the year 2020 and 2021 for the CSFL merger. The core system conversion for the CSFL merger was completed during the second quarter of 2021. The Company expects to achieve further operating cost savings and other business synergies as a result of the acquisition, which are not reflected in the pro forma amounts below. The total revenues presented below represent pro-forma net interest income plus pro-forma noninterest income.

The disclosures regarding the results of operations for CSFL subsequent to the acquisition date are omitted as this information is not practical to obtain. The majority of the fixed costs and purchase accounting entries were booked on the Company’s core system making it impractical to determine CSFL’s results of operation on a stand-alone basis.

​

The Company’s other investment securities consist of non-marketable equity securities that have no readily determinable market value. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. As of December 31, 2021, the Company has determined that there was no impairment on its other investment securities.

The amortized cost and fair value of debt and equity securities at December 31, 2021 by contractual maturity are detailed below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties.

Management evaluates securities for impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby Management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the provision for credit losses. Consideration is given to (1) the financial condition and near-term prospects of the issuer including looking at default and delinquency rates, (2) the outlook for receiving the contractual cash flows of the investments, (3) the length of time and the extent to which the fair value has been less than cost, (4) our intent and ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value or for a debt security whether it is more-likely-than-not that we will be required to sell the debt security prior to recovering its fair value, (5) the anticipated outlook for changes in the general level of interest rates, (6) credit ratings, (7) third-party guarantees, and (8) collateral values. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, the results of reviews of the issuer’s financial condition, and the issuer’s anticipated ability to pay the contractual cash flows of the investments. The Company performed an analysis that determined that the following securities have a zero expected credit loss: U.S. Treasury Securities, Agency-Backed Securities including securities issued by Ginnie Mae, Fannie Mae, FHLB, FFCB and SBA. All of the U.S. Treasury and Agency-Backed Securities have the full faith and credit backing of the United States Government or one of its agencies. Municipal securities and all other securities that do not have a zero expected credit loss are evaluated quarterly to determine whether there is a credit loss associated with a decline in fair value. All debt securities in an unrealized loss position as of December 31, 2021 continue to perform as scheduled and we do not believe that there is a credit loss or that a provision for credit losses is necessary. Also, as part of our evaluation of our intent and ability to hold investments for a period of time sufficient to allow for any anticipated recovery in the market, we consider our investment strategy, cash flow needs, liquidity position, capital adequacy and interest rate risk position. We do not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that we will be required to sell the debt securities. See Note 1—Summary of Significant Account Policies for further discussion.

Management continues to monitor all of our securities with a high degree of scrutiny. There can be no assurance that we will not conclude in future periods that conditions existing at that time indicate some or all of its securities may be sold or would require a charge to earnings as a provision for credit losses in such periods.

At December 31, 2021 and 2020, investment securities with a carrying value of $2.1 billion were pledged to secure public funds deposits and for other purposes required and permitted by law. At December 31, 2021 and 2020, the carrying amount of the securities pledged to collateralize repurchase agreements was $471.3 million and $515.9 million, respectively.

The following is a summary of total loans:

(Dollars in thousands) |  | 2021 |  | 2020 |
Loans: | ​ | ​ |  | ​ | ​ |  | ​
Construction and land development (1) | ​ | $ | 2,029,216 | ​ | $ | 1,890,846 | ​

Loans, net | ​ | $ | 23,626,359 | ​ | $ | 24,206,825 | ​

| (1) | Construction and land development includes loans for both commercial construction and development, as well as loans for 1-4 family construction and lot loans.

| (2) | Consumer owner occupied real estate includes loans on both 1-4 family owner occupied property, as well as loans collateralized by 1-4 family owner occupied properties with a business intent.

| (3) | As a result of the conversion of legacy CenterState’s core system to the Company’s core system completed during the second quarter of 2021, several loans were reclassified to conform with the Company’s current loan segmentation, most notably residential investment loans were reclassified from Consumer Owner Occupied to Other Income Producing Property, and some multi-family loans were reclassified from Other Income Producing Property to Commercial Non-Owner Occupied. Prior period loan balances presented above were revised to conform with the current loan segmentation.

In accordance with the adoption of ASU 2016-13, the above table reflects the loan portfolio at the amortized cost basis for the years ended December 31, 2021 and 2020, to include net deferred costs of $15.9 million compared to net deferred fees of $35.6 million, respectively, and unamortized discount total related to loans acquired of $68.0 million and $97.7 million, respectively. Accrued interest receivable (AIR) of $70.6 million and $93.9 million are accounted for separately and reported in other assets for the periods December 31, 2021 and 2020.

​

As part of the ongoing monitoring of the credit quality of our loan portfolio, Management tracks certain credit quality indicators, including trends related to (i) the level of classified loans, (ii) net charge-offs, (iii) non-performing loans (see details below), and (iv) the general economic conditions of the markets that we serve.

​

The Company utilizes a risk grading matrix to assign a risk grade to each commercial loan. Classified loans are assessed at a minimum every six months. A description of the general characteristics of the risk grades is as follows:

| ● | Pass—These loans range from minimal credit risk to average, however, still acceptable credit risk.

| ● | Special mention—A special mention loan has potential weaknesses that deserve Management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date.

| ● | Substandard—A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness, or weaknesses, that may jeopardize the liquidation of the debt. A substandard loan is characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.

| ● | Doubtful—A doubtful loan has all of the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of the currently existing facts, conditions and values, highly questionable and improbable.

​

Construction and land development loans in the following table are on commercial and speculative real estate. Consumer owner occupied loans are collateralized by 1-4 family owner occupied properties with a business intent. As noted previously, as a result of the conversion of legacy CenterState’s core system to the Company’s core system

There is no interest income recognized during the period on nonaccrual loans. The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Loans on nonaccrual status in which there is no allowance assigned are individually evaluated loans that do not carry a specific reserve. See Note 1—Summary of Significant Accounting Policies for further detailed on individually evaluated loans.

The Bank designates individually evaluated loans (excluding TDRs) on non-accrual with a net book balance exceeding the designated threshold as collateral dependent loans. Collateral dependent loans are loans for which the repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. These loans do not share common risk characteristics and are not included within the collectively evaluated loans for determining ACL. Under ASC 326-20-35-6, the Bank has adopted the collateral maintenance practical expedient to measure the ACL based on the fair value of collateral. The ACL is calculated on an individual loan basis based on the shortfall between the fair value of the loan's collateral, which is adjusted for selling costs, and amortized cost. If the fair value of the collateral exceeds the amortized cost, no allowance is required. During the second quarter of 2020, the Bank increased the threshold limit for loans individually evaluated from $500,000 to $1.0 million. The significant changes above in collateral percentage are due to appraisal value updates or changes in the number of loans within the asset class and collateral type. Overall collateral dependent loans increased by $8.4 million from December 31, 2020 compared to the balance at December 31, 2021

In the course of resolving delinquent loans, the Bank may choose to restructure the contractual terms of certain loans. Any loans that are modified are reviewed by the Bank to determine if a TDR, sometimes referred to herein as a restructured loan, has occurred. The Bank designates loan modifications as TDRs when it grants a concession to a borrower that it would not otherwise consider due to the borrower experiencing financial difficulty (FASB ASC Topic 310-40). The concessions granted on TDRs generally include terms to reduce the interest rate, extend the term of the debt obligation, or modify the payment structure on the debt obligation. See Note 1—Summary of Significant Accounting Policies for how such modifications are factored into the determination of the ACL.

Loans on nonaccrual status at the date of modification are initially classified as nonaccrual TDRs. Loans on accruing status at the date of concession are initially classified as accruing TDRs if the note is reasonably assured of repayment and performance is expected in accordance with its modified terms. Such loans may be designated as nonaccrual loans subsequent to the concession date if reasonable doubt exists as to the collection of interest or principal under the restructuring agreement. Nonaccrual TDRs are returned to accruing status when there is economic substance to the restructuring, there is documented credit evaluation of the borrower’s financial condition, the remaining balance is reasonably assured of repayment in accordance with its modified terms, and the borrower has demonstrated sustained repayment performance in accordance with the modified terms for a reasonable period of time (generally a minimum of six months).

The Company elected the accounting policy in the CARES Act to not apply TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic if the concession met the criteria stipulated in the CARES Act. Details in regards to the Company’s implemented loan modification programs in response to the COVID-19 pandemic under the CARES Act is disclosed under the Note 1—Summary of Significant Accounting Policies.

At December 31, 2021 and 2020, the balance of accruing TDRs was $11.2 million and $14.6 million, respectively. The Company had $537,000 and $576,000 remaining availability under commitments to lend additional funds on restructured loans at December 31, 2021 and 2020, respectively. The amount of specific reserve associated with restructured loans was $2.5 million and $1.2 million at December 31, 2021 and 2020, respectively.

Securities Sold Under Agreements to Repurchase

​

Securities sold under agreements to repurchase (“repurchase agreements”) represent funds received from customers, generally on an overnight or continuous basis, which are collateralized by investment securities owned or, at times, borrowed and re-hypothecated by the Company. Repurchase agreements are subject to terms and conditions of the master repurchase agreements between the Company and the client and are accounted for as secured borrowings. The Company monitors the fair value of the underlying securities on a daily basis. Some securities underlying these agreements include arrangements to resell securities from broker-dealers approved by the Company. Repurchase agreements are reflected at the amount of cash received in connection with the transaction and included in federal funds purchased and securities sold under agreements to repurchase on the consolidated balance sheets.

At December 31, 2021 and December 31, 2020, the Company’s repurchase agreements totaled $400.0 million and $394.9 million, respectively. All of the Company’s repurchase agreements were overnight or continuous (until-further-notice) agreements at December 31, 2021 and December 31, 2020. These borrowings were collateralized with government, government-sponsored enterprise, or state and political subdivision-issued securities with a carrying value of $471.3 million and $515.9 million at December 31, 2021 and December 31, 2020, respectively. Declines in the value of the collateral would require the Company to increase the amounts of securities pledged.

(5) These subordinated notes were not classified as Tier 2 Capital for regulatory capital purposes.

Short-Term Borrowings

​

The Company has from time-to-time entered into borrowing agreements with the FHLB and FRB. Borrowings under these agreements are collateralized by stock in the FHLB, qualifying first and second mortgage residential loans, investment securities, and commercial real estate loans under a blanket-floating lien.

​

As of December 31, 2021 and 2020, there were no outstanding short-term borrowings. For the years ended December 31, 2021 and 2020, the average balance for short-term borrowings was $2.0 million and $745.9 million,

F-49

respectively. The year-to-date weighted average cost for the years ended December 31, 2021 and 2020 was 2.22% and 0.63%, respectively. Net eligible loans of the Company pledged via a blanket lien to the FHLB for advances and letters of credit at December 31, 2021, were approximately $3.7 billion and investment securities and cash pledged were approximately $227.6 million. This allows the Company a total borrowing capacity at the FHLB of approximately $2.8 billion. After accounting for letters of credit totaling $12.0 million, the Company had unused net credit available with the FHLB in the amount of approximately $2.8 billion at December 31, 2021. The Company also has a total borrowing capacity at the FRB of $981.1 million at December 31, 2021 secured by a blanket lien on $1.6 billion in net eligible loans of the Company. The Company had no outstanding borrowings with the FRB at December 31, 2021 and 2020.

​

During the fourth quarter of 2020, we paid-off early our FHLB advances of $700.0 million and terminated the interest rate swaps related to these advances at a cost of $38.8 million reflected in Noninterest Expense in the Consolidated Statements of Income.

​

Junior Subordinated Debt

​

The obligations of the Company with respect to the issuance of the capital securities constitute a full and unconditional guarantee by the Company of the trusts’ obligations with respect to the capital securities. Subject to certain exceptions and limitations, the Company may elect from time to time to defer interest payments on the junior subordinated debt securities, which would result in a deferral of distribution payments on the related capital securities.

​

All of the Company’s junior subordinated debt is callable after five years from issuance. Therefore, all of the junior subordinated debt is callable at December 31, 2021.

​

As of December 31, 2021, the sole assets of the trusts were an aggregate of $117.2 million, net of unamortized discount, of the Company’s junior subordinated debt securities with like maturities and like interest rates to the trust preferred securities.

​

As of December 31, 2021, the Company recorded a $117.2 million liability for the junior subordinated debt securities, net of a $1.4 million discount recorded on Citizens South Banking Corporation Statutory Trust I, Community Capital Statutory Trust I, FCRV Statutory Trust I and Provident Community Bancshares Capital Trust I and II. The Company, as issuer, can call any of these subordinated debt securities without penalty. If the Company were to call the securities, the amount paid to the holders would be $118.6 million and the Company would fully amortize any remaining discount into interest expense. The remaining discount is being amortized over a four-year period.

​

As of December 31, 2021, and 2020, there was $117.2 million (net of discount of $1.4 million) and $144.3 million (net of discount of $14.1 million), respectively, in junior subordinated debt. The weighted average cost of the junior subordinated debt at period end December 31, 2021 was 1.89% and the weighted average cost year to date for the year ended December 31, 2021 of 1.97%. This does not take into account the unamortized discount at period end or the discount amortization recorded during the year. If the discount were taken into account, the weighted average cost year to date would be 2.85%. This compares to a weighted average cost of the junior subordinated debt at period end December 31, 2020 of 2.05% and the weighted average cost year to date for the year ended December 31, 2020 of 2.51%. If the discount were taken into account, the weighted average cost year to date would be 3.56% in 2020. During the second quarter of 2021, the Company redeemed $38.5 million in trust preferred securities that were acquired in the merger with CSFL. With the redemption of the trust preferred securities, the remaining fair value mark on these borrowings of $11.7 million was written off as an extinguishment of debt cost.

​

Pursuant to the Basel III rules adopted by the bank regulatory agencies in July 2013, financial institutions with less than $15 billion in total assets may continue to include their trust preferred securities issued prior to May 19, 2010 in Tier 1 capital, but cannot include in Tier 1 capital any trust preferred securities issued after such date. A financial institution may continue to include its trust preferred securities in Tier 1 capital if it exceeds $15 billion in total assets through organic growth, but if it exceeds $15 billion in total assets through an acquisition or enters into an acquisition after exceeding $15 billion in total assets through organic growth, then the trust preferred securities would no longer be included in Tier 1 capital. Therefore, upon closing on the merger with CSFL in 2020, all of the Company’s trust preferred securities are no longer included in Tier 1 capital. Following the merger, these trust preferred securities are now included in Tier 2 capital for regulatory capital purposes.

Subordinated Debt and Notes

​

As of December 31, 2021, the Company recorded a $209.9 million liability for the subordinated debt, which was net of $3.1 million in debt issuance costs recorded on the CenterState subordinated debt issuance of $200.0 million. The remaining balance of the debt issuance costs are being amortized over a seven and one-half year period.

​

The weighted average cost of the subordinated debt at period end December 31, 2021 was 5.80% and the weighted average cost year to date for the year ended December 31, 2021 of 5.81%. The weighted average cost of the subordinated debt at period end December 31, 2020 was 5.78% and the weighted average cost year to date for the year ended December 31, 2020 of 5.69%. This does not take into account the amortization of the debt issuance costs. If the debt issuance costs were taken into account, the weighted average cost year to date for the year ended December 31, 2021 and 2020 would be 6.06% and 5.93%, respectively.

​

Qualifying subordinated debt can be included in Tier 2 capital for regulatory capital purposes. Of our subordinated debt, the amounts for the Landmark Bancshares and CenterState Bank Corporation totaling $213.0 million qualify for Tier 2 capital at December 31,2021. During the second quarter of 2021, the Company redeemed $25.0 million in subordinated debentures and repaid $11.0 million of subordinated notes that matured. The subordinated notes for Residential Warranty Corp. and Messiah College totaling $11.0 million that matured in 2021 did not qualify for Tier 2 capital purposes.

​

Line of Credit

​

On November 15, 2021, the Company entered into an amendment and restatement to its Credit Agreement (the “Agreement”) with U.S. Bank National Association (the “Lender”). The Agreement provides for a $100 million unsecured line of credit by the Lender to the Company. The maturity date of the Agreement is November 14, 2022, provided that the Agreement may be extended subject to the approval of the Lender. Borrowings by the Company under the Agreement will bear interest at a rate per annum equal to 1.40% plus monthly reset term SOFR Rate. As of December 31, 2021 and 2020, there was no outstanding balance associated with the line of credit. For the year ended December 31, 2021, the average balance for U.S. Bank line of credit was $2.0 million and year-to-date weighted average cost for the years ended December 31, 2021 was 2.22%. There was no outstanding balance on the U.S. Bank line of credit during 2020.

​

The provision for income taxes differs from that computed by applying the federal statutory income tax rate of 21% in 2021, 2020 and 2019 to income before provision for income taxes, as indicated in the following analysis:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ | ​ | $ | 128,736 | ​ | $ | (16,660) | ​ | $ | 43,942 | ​

​

The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

​

Under the CARES Act, tax law changed to include the ability to carry back net operating losses ("NOLs") generated in 2018 through 2020 for five years, which was previously disallowed. Due to differences in tax and GAAP accounting rules, which relates to a tax method change to fair value for loans, the Company filed a short period tax return as of the merger date, which generated a NOL. This loss was carried back to the 2015 through 2017 tax years at a 35% tax rate, generating an income tax benefit of $31.5 million during 2020.

The Company had federal net operating loss (“NOL”) and realized built-in loss carryforwards of $61.8 million and $91.9 million for the years ended December 31, 2021 and 2020, respectively, which expire in varying amounts between 2026 to 2036. All of the Company's loss carryforwards are subject to Section 382 of the Internal Revenue Code, which places an annual limitation on the amount of federal net operating loss carryforwards which the Company may utilize after a change in control, and also limits the Company's ability to utilize certain tax deductions (realized built-in losses or RBIL) due to the existence of a Net Unrealized Built-in Loss (NUBIL) at the time of the change in control. The Company acquired federal net operating loss carryforwards of $62.9 million in the 2020 merger with CSFL. These acquired NOLs are subject to a combined annual Section 382 limitation of $16.0 million. In total, the allowable deduction for all loss carryforwards on an annual basis is $20.7 million. The Company is allowed to carry forward any such limited RBIL under terms similar to those related to NOLs.

The Company also has acquired state net operating losses in Georgia, Florida and Alabama. These are also subject to annual limitations under Section 382, similar to the federal NOLs. The Company expects all Section 382 limited carryforwards to be realized within the applicable carryforward period.

The Company has state net operating loss carryforwards of $169.4 million and $222.9 million for the years ended December 31, 2021 and 2020, respectively, most of which expire in varying amounts through 2039. There is a valuation allowance of $4.8 million on $122.5 million of state operating loss carryforwards at the parent company for which realizability is uncertain.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more

likely than not that the Company will realize the benefits of these deferred tax assets, net of the valuation allowance at December 31, 2021.

​

As of December 31, 2021, the Company had no material unrecognized tax benefits or accrued interest and penalties. It is the Company's policy to account for interest and penalties accrued relative to unrecognized tax benefits as a component of income tax expense.

​

Generally, the Company’s federal and state income tax returns are no longer subject to examination by taxing authorities for years prior to 2018.

Note 16—Restrictions on Subsidiary Dividends, Loans, or Advances

The Company pays cash dividends to shareholders from its assets, which are mainly provided by dividends from its banking subsidiary. However, certain restrictions exist regarding the ability of its subsidiary to transfer funds to the Company in form of cash dividends, loans or advances. The approval of the OCC is required if the total of all dividends declared by the Bank in any calendar year exceeds the total of its net profits for that year combined with its retained net profits for the preceding two years, less any required transfers to surplus. The federal banking agencies have issued policy statements which provide that bank holding companies and insured banks should generally pay dividends only out of current earnings.

​

During 2021, the Bank paid dividends to the Company of $200.0 million. These funds were used to repurchase approximately $146.4 million of Company stock on the open market, to pay dividends to shareholders of approximately $135.2 million and to redeem and pay-off trust preferred and subordinated debt of $74.5 million during 2021. During first quarter of 2020, the Bank paid special dividends to the Company totaling $24.7 million for which SCBFI approval was not required. These funds were used to repurchase Company stock on the open market totaling $24.7 million during the first quarter of 2020. The Bank also paid a special dividend of $33.0 million during the first quarter of 2020 to provide the Company more general operating liquidity during the COVID-19 pandemic. The Bank paid approximately $32.6 million to fund quarterly shareholder divided payments.

Under Federal Reserve regulations, the bank is also limited as to the amount it may lend to the Company. The maximum amount available for transfer from the bank to the Company in the form of loans or advances was approximately $503.2 million and $479.5 million at December 31, 2021 and 2020, respectively.

Note 17—Retirement Plans

The Company and its subsidiary had a non-contributory defined benefit pension plan covering all employees hired on or before December 31, 2005, who had attained age 21, and who had completed one year of eligible service. The Company’s funding policy on the pension plan was based principally, among other considerations, on contributing an amount necessary to satisfy the Internal Revenue Service’s funding standards. Effective July 1, 2009, the Company suspended the accrual of benefits for pension plan participants under the non-contributory defined benefit plan. The plan was terminated in the second quarter of 2019.

During 2018, we made the decision to terminate the non-contributory defined benefit pension plan. We received approval from the IRS through a determination letter in the fourth quarter of 2018 to proceed with the termination. The termination of the pension plan was recorded during the second quarter of 2019 and distributions of assets from the plan were fully paid out by the fourth quarter of 2019. During the second quarter of 2019, the Company recorded a charge of $9.5 million related to the termination of the pension plan in the Consolidated Statement of Income. This cost was the result of the recognition of the pre-tax losses from the pension plan that were recorded and held in accumulated other comprehensive income of $7.7 million and the write-off of the pension plan asset of $1.8 million. Participants had the option to be fully paid out in a lump sum or be paid through an annuity over time. If the participant chose the annuity, the funds were placed in an annuity product with a third-party.

The following sets forth the pension plan’s funded status and amounts recognized in the Company’s accompanying consolidated financial statements:

​

Due to the termination of the pension plan in 2019, there was no benefit obligation or plan assets at December 31, 2021 and 2020. The weighted-average assumptions used to determine net periodic pension cost are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year ended |
​ | ​ | December 31, |
​ | ​ | 2021 | ​ | 2020 | ​ | 2019 |
Discount rate |  | — | % | — | % | 4.10 | %
Expected long-term return on plan assets |  | — | % | — | % | 7.75 | %

​

For the year ended December 31, 2019, the discount rate of 4.10% was determined by matching the projected benefit obligation cash flows of the plan to an independently derived yield curve, to arrive at the single equivalent rate.

The policy, as established by the Investment Committee of the Defined Benefit Pension Plan, sought to maximize return within reasonable and prudent levels of risk. The overall long-term objective of the Plan was to achieve a rate of return that exceeds the actuarially assumed rate of return. The investment policy was reviewed on a regular basis and revised when appropriate based on the legal or regulatory environment, market trends, or other fundamental factors. In determining the long-term rate of return for the pension plan, the Company considered historical rates of return and the nature of the plan’s investments. Prior to making the decision to terminate the Plan, the Plan assets were divided among various investment classes with allowable allocation percentages as follows: Equities 55 - 65%, Fixed Income 20 - 40%, Cash Equivalents 0 - 35%. During 2019 before the termination of the pension plan, approximately 98% of pension plan assets were invested with Fixed Income Assets, and approximately 2% of pension plan assets were held in cash equivalents. When the decision was made to terminate the plan, the Investment Committee and the Company made the decision to move the Plan assets into less risky investments of Cash Equivalents and Fixed Income Assets and out of Equities. The plan made no purchases of the Company’s stock during 2021, 2020 and 2019. The difference between actual and expected returns on plan assets was accumulated and amortized over future periods and, therefore, affects the recognized expenses in such future periods.

​

Expenses incurred and charged against operations with regard to all of the Company’s retirement plans were as follows:

The Company and its subsidiaries have a Safe Harbor plan. Under the plan, electing employees are eligible to participate after attaining age 18. Plan participants elect to contribute portions of their annual base compensation in any combination of pre-tax deferrals or Roth post-tax deferrals subject to the annual IRS limit. Employer contributions may be made from current or accumulated net profits. Participants may elect to contribute 1% to 50% of annual base

compensation as a pre-tax contribution. Employees participating in the plan receive a 100% matching of their 401(k) plan contribution, up to 4% of salary. Effective January 1, 2018, employees are eligible for an additional 2% discretionary matching contribution contingent upon achievement of the Company’s annual financial goals and payable the first quarter of the following year. Based on our financial performance in 2021, we do not expect to pay a discretionary matching contribution in the first quarter of 2022. As a result of the merger with CSFL in 2020, all former CSFL employees became eligible to participate in the Company’s 401(k) plan as of legal close. CSFL’s existing 401(k) plan balances were merged into the Company’s 401(k) plan on January 4, 2021.

Employees can enter the savings plan on or after the first day of each month. The employee may enter into a salary deferral agreement at any time to select an alternative deferral amount or to elect not to defer in the Plan. If the employee does not elect an investment allocation, the plan administrator will select a retirement-based portfolio according to the employee’s number of years until normal retirement age. The plan’s investment valuations are generally provided on a daily basis.

Note 18—Post-Retirement Benefits

At December 31, 2021, the Company and its subsidiary have two post-retirement health and life insurance benefit plans, SouthState Bank Retiree Medical Plan (the “retiree medical plan”) and the First Federal Retiree Welfare Plan (the “retiree welfare plan”).

Retiree Medical Plan

Under the retiree medical plan, post-retirement health and life insurance benefits are provided to eligible employees, such benefits being limited to those employees of the Company eligible for early retirement under the pension plan on or before December 31, 1993, and former employees who are currently receiving benefits. The plan was unfunded at December 31, 2021, and the liability for future benefits has been recorded in the consolidated financial statements.

The following sets forth the retiree medical plan’s funded status and amounts recognized in the Company’s accompanying consolidated financial statements:

Note 19—Share-Based Compensation

Compensation cost is recognized for stock options and restricted stock awards issued to employees. Compensation cost is measured as the fair value of these awards on their date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used as the fair value of restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period for stock option awards and as the restriction period for restricted stock awards. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

Our 2004, 2012, 2019 and 2020 share-based compensation plans are long-term retention plans intended to attract, retain, and provide incentives for key employees and non-employee directors in the form of incentive and non-qualified stock options, restricted stock, and restricted stock units (“RSUs”). Our 2020 plan was adopted by our shareholders at our annual meeting on October 29, 2020. The Company also assumed the obligations of CSFL under various equity incentive plans pursuant to the merger of CSFL on June 7, 2020.

Stock Options

With the exception of non-qualified stock options granted to directors under the 2004 and 2012 plans, which in some cases may be exercised at any time prior to expiration and in some other cases may be exercised at intervals less than a year following the grant date, incentive stock options granted under our 2004, 2012, 2019 and 2020 plans may not be exercised in whole or in part within a year following the date of the grant, as these incentive stock options become exercisable in 25% increments pro ratably over the four-year period following the grant date. The options are granted at an exercise price at least equal to the fair value of the common stock at the date of grant and expire ten years from the date of grant. No options were granted under the 2004, 2012 or 2019 plans after January 26, 2012, February 1, 2019, and October 29, 2020, respectively, and the plans are closed other than for any options still unexercised and outstanding. The 2020 plan is the only plan from which new share-based compensation grants may be issued. It is the Company’s policy to grant options out of the 2,072,245 shares registered under the 2020 plan.

Activity in the Company’s stock option plans is summarized in the following table. All information has been retroactively adjusted for stock dividends and stock splits.

The fair value of options is estimated at the date of grant using the Black-Scholes option pricing model and expensed over the options’ vesting periods. We have not granted any stock options for the years ended December 31, 2021, 2020 and 2019, and therefore, we have not used the Black-Scholes option pricing model to fair value options.

As of December 31, 2021 and 2020, there were no unrecognized compensation costs related to non-vested stock option grants under the plans. As of December 31, 2019, there was $720,000 of total unrecognized compensation cost related to non-vested stock option grants under the plans. The total fair value of shares vested during the years ended December 31, 2021, 2020, and 2019 was approximately $0, $1.4 million, and $799,000, respectively. Compensation expense of $0, $720,000, and $641,000 was recorded in 2021, 2020, and 2019, respectively. Of the expense in 2020,

approximately $481,000 was recognized in June 2020 due to the acceleration of vesting of stock options through the merger with CSFL.

Restricted Stock

We, from time-to-time, grant shares of restricted stock to key employees and non-employee directors. These awards help align the interests of these employees and directors with the interests of our shareholders by providing economic value directly related to increases in the value of our stock. The value of the stock awarded is established as the fair market value of the stock at the time of the grant. We recognize expenses, equal to the total value of such awards, ratably over the vesting period of the stock grants. Restricted stock grants to employees typically “cliff vest” after four years. Grants to non-employee directors typically vest within a 12-month period.

​

All restricted stock agreements are conditioned upon continued employment, or service in the case of directors. Termination of employment prior to a vesting date, as described below, would terminate any interest in non-vested shares. Prior to vesting of the shares, as long as employed by the Company, the key employees and non-employee directors will have the right to vote such shares and to receive dividends paid with respect to such shares. All restricted shares will fully vest in the event of change in control of the Company or upon the death of the recipient. Due to the merger between the Company and CSFL effective June 7, 2020, a total of 29,303 restricted stock awards became fully vested.

Non-vested restricted stock for the year ended December 31, 2021 is summarized in the following table. All information has been retroactively adjusted for stock dividends and stock splits.

​

The Company granted 0, 9,145, and 8,934 shares for the years ended December 31, 2021, 2020, and 2019, respectively. The weighted-average- grant-date fair value of restricted shares granted in 2021, 2020, and 2019 was $0, $55.96, and $73.34, respectively. Compensation expense of $370,000, $1.5 million, and $1.7 million was recorded in 2021, 2020, and 2019, respectively. Of the expense in 2020, approximately $704,000 was recognized in June 2020 due to the acceleration of vesting of restricted stock awards through the merger with CSFL.

The vesting schedule of these shares as of December 31, 2021 is as follows:

​

​ | ​ | ​ | ​
​ |  | Shares |
2022 |  | 750 | ​
2023 |  | 750 | ​
2024 |  | 1,566 | ​
​ |  | 3,066 | ​

​

As of December 31, 2021, there was $166,000 of total unrecognized compensation cost related to non-vested restricted stock granted under the plans. The cost is expected to be recognized over a weighted-average period of 2.65 years as of December 31, 2021. The total fair value of shares vested during the years ended December 31, 2021, 2020 and 2019 was approximately $448,000, $4.6 million, and $3.0 million, respectively.

Restricted Stock Units (“RSU”)

We, from time-to-time, also grant performance RSUs and time-vested RSUs to key employees. These awards help align the interests of these employees with the interests of our shareholders by providing economic value directly related to our performance. Some performance RSU grants contain a three-year performance period while others contain a one to two-year performance period and a time-vested requirement (generally two to four years from the grant date). We communicate threshold, target, and maximum performance RSU awards and performance targets to the applicable key employees at the beginning of a performance period. Due to the merger with CSFL, all legacy and assumed performance based restricted stock units converted to a time-vesting requirement. With respect to some long-term

F-62

Table of Contents

incentive awards, dividend equivalents are accrued at the same rate as cash dividends paid for each share of the Company’s common stock during the performance or time-vested period, and subsequently paid when the shares are issued on the vesting or settlement date. The value of the RSUs awarded is established as the fair market value of the stock at the time of the grant. We recognize expenses on a straight-line basis typically over the performance and vesting/or time-vesting periods based upon the probable performance target, as applicable, that will be met. For the year ended December 31, 2021, we accrued for 100.0% of the RSUs granted. Due to the merger between the Company and CSFL effective June 7, 2020, a total of 242,018 restricted stock units became fully vested in 2020.

​

Nonvested RSUs for the year ended December 31, 2021 is summarized in the following table.

Employee Stock Purchase Plan

The Company previously registered 363,825 shares of common stock in connection with the establishment of an Employee Stock Purchase Plan. At the annual shareholders meeting on October 29, 2020, a proposal was adopted to increase the shares of common stock that may be issued under the plan by up to 1,400,000 shares. The plan is available to all employees who have attained age 21 and completed six months of service. The Company currently has approximately 1.4 million shares available for issuances under the plan. The price at which common stock may be purchased for each quarterly option period is the lesser of 95% of the common stock’s fair value on either the first or last day of the quarter.

The 2002 Employee Stock Purchase Plan permits eligible employees to purchase Company stock at a discounted price. Beginning July 1, 2009, the 15% discount was reduced to 5%. Employees purchased 33,013, 32,476 and 21,100 shares in 2021, 2020 and 2019, respectively, through the Employee Stock Purchase Plan. The Company recognized $126,000, $81,000 and $75,000 in share-based compensation expense for the years ended December 31, 2021, 2020 and 2019, respectively.

Under other arrangements where directors or officers surrendered currently owned shares to the Company to acquire proceeds for exercising stock options or paying taxes on currently vesting restricted stock, the Company repurchased 13,412, 122,708, and 35,674 shares at a cost of $1.1 million, $7.7 million, and $2.5 million in 2021, 2020, and 2019, respectively. Of the amounts in 2020, 86,263 shares at a cost of $5.2 million were related to the vesting of restricted stock due to the merger with CSFL.

Note 21—Lease Commitments

On January 1, 2019, we adopted the requirements of Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842). The purpose of the update was to increase transparency and comparability between organizations that enter into lease agreements. The key difference between the previous guidance and the update is the recognition of a right-of-use asset (ROU) and lease liability on the statement of financial position for those leases previously classified as operating leases under the old guidance. ASC Topic 842 defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. In applying this standard, we reviewed our material contracts to determine if they included a lease by this new definition and did not identify any new leases. Our lease agreements in which ASC Topic 842 has been applied are primarily for real estate properties, including retail branch locations, operations and administration locations and stand-alone ATM locations. We performed an analysis on equipment leases for the implementation of ASC Topic 842 and determined the number and dollar amount of our equipment leases was not material.

​

A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We chose the transition method of adoption where we initially apply the new lease standard at the effective date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption if applicable. Therefore, we applied this standard to all existing leases as of the adoption date of January 1, 2019, recording a ROU asset and a lease liability in an equal amount. We recorded a ROU asset and lease liability of $82.2 million at the commencement date of January 1, 2019. We did not have a cumulative-effect adjustment to the opening balance of retained earnings at commencement and the adoption of ASC Topic 842 did not have a material impact on our consolidated income statement.

​

As of December 31, 2021 and 2020, we had operating ROU assets of $110.3 million and $113.4 million, respectively, and operating lease liabilities of $115.9 million and $118.3 million, respectively. We maintain operating leases on land and buildings for our operating centers, branch facilities and ATM locations. Most leases include one or more options to renew, with renewal terms extending up to 23 years. The exercise of renewal options is based on the sole judgment of management and what they consider to be reasonably certain given the environment today. Factors in determining whether an option is reasonably certain of exercise include, but are not limited to, the value of leasehold improvements, the value of renewal rate compared to market rates, and the presence of factors that would cause a significant economic penalty to us if the option is not exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet and instead are recognized in lease expense on a straight-line basis over the lease term. We do not sublease any portion of these locations to third parties.

As of December 31, 2021, the Company also holds a small number of finance leases assumed in connection to the CSFL merger completed in 2020. These leases are all real estate leases. Terms and conditions are similar to those real estate operating leases described above. Lease classifications from the acquired institutions were retained. At December 31, 2021, we do not maintain any leases with related parties, and we determined that the number and dollar amount of our equipment leases was immaterial. As of December 31, 2021, we have two additional operating leases that have not yet commenced of $22,000. These operating leases will commence in fiscal year 2022 with a lease term of 13 months.

Note 22—Contingent Liabilities

The Company has been named as defendant in various legal actions, arising from its normal business activities, in which damages in various amounts are claimed. The Company is also exposed to litigation risk related to the prior business activities of banks acquired through whole bank acquisitions. Although the amount of any ultimate liability with respect to such matters cannot be determined, in the opinion of management, any such liability will not have a material effect on the Company’s consolidated financial statements.

The Company and its subsidiary are involved at times in certain litigation arising in the normal course of business. In the opinion of management as of December 31, 2021, there is no pending or threatened litigation that will have a material effect on the Company’s consolidated financial position or results of operations.

Note 23—Related Party Transactions

During 2021 and 2020, the Company’s banking subsidiary had loan and deposit relationships with certain related parties, principally directors and executive officers, their immediate families and their business interests. All of these relationships were in the ordinary course of business at rates and terms substantially consistent with similar transactions with unrelated parties. Loans outstanding to this group (including immediate families and business interests) totaled $10.1 million and $28.7 million at December 31, 2021 and 2020 respectively. During 2021, $102.2 million of new loans were made to this group while repayments of $120.8 million were received during the year. During 2020, $12.4 million of new loans were made to this group while repayments of $17.7 million were received during the year. There were also additions to related party loans of $31.8 million due to the addition of new related parties through the acquisition of CSFL, and reductions to related party loans of $35.3 million due to the removal of related parties through the acquisition of CSFL in 2020. Related party deposits totaled approximately $21.4 million and $18.8 million at December 31, 2021 and 2020, respectively.

Note 24—Financial Instruments with Off-Balance Sheet Risk

The Company’s subsidiary is a party to credit related financial instruments with off-balance sheet risks in the normal course of business to meet the financing needs of their customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees. Such commitments involve, to varying degrees, elements of credit, interest rate, or liquidity risk in excess of the amounts recognized in the consolidated balance sheets. The contract amounts of these instruments express the extent of involvement the subsidiary has in particular classes of financial instruments.

The subsidiary’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, standby letters of credit, and financial guarantees is represented by the contractual amount of those instruments. The subsidiary uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. At December 31, 2021 and 2020, the following financial instruments, whose contract amounts represent credit risk, were outstanding:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31, | ​
(Dollars in thousands) | ​ | 2021 | ​ | 2020 | ​
Commitments to extend credit | ​ | $ | 7,416,311 | ​ | $ | 5,929,845 | ​
Standby letters of credit and financial guarantees | ​ |  | 71,824 | ​ |  | 76,507 | ​
​ | ​ | $ | 7,488,135 | ​ | $ | 6,006,352 | ​

​

As of December 31, 2021 and 2020, the subsidiary had recorded a liability for expected credit losses on unfunded commitments, excluding unconditionally cancellable exposures and letters of credit, of $30.5 million and $43.4 million, respectively, which was recorded in Other Liabilities on the Balance Sheet. See Note 1—Summary of Significant Accounting Policies for discussion of liability recorded for expected credit losses on unfunded commitments.

Commitments to Extend Credit

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The Bank evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the bank upon extension of credit, is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and personal guarantees. Unfunded commitments under commercial lines-of-credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines-of-credit are uncollateralized and usually do not contain a specified maturity date and may not be drawn to the extent to which the banking subsidiary is committed.

Standby Letters of Credit and Financial Guarantees

Standby letters of credit and financial guarantees are conditional commitments issued by the banking subsidiary to guarantee the performance of a customer to a third-party. Those letters of credit and guarantees are primarily issued to support public and private borrowing arrangements. Essentially, all standby letters of credit have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the customer.

Note 25—Fair Value

FASB ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value under accounting principles generally accepted in the United States, and enhances disclosures about fair value measurements. FASB ASC 820 clarifies that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions.

The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale and trading securities, derivative contracts, mortgage loans held for sale, and MSRs are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, OREO, bank properties held for sale, and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets.

FASB ASC 820 establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

​ | ​
Level 1 | Observable inputs such as quoted prices in active markets;
Level 2 | Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
Level 3 | Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

The following is a description of valuation methodologies used for assets recorded at fair value.

Trading Securities

​

The fair values of trading securities are determined as follows: (1) for those securities that have traded prior to the date of the consolidated balance sheet but have not settled (date of sale) until after such date, the sales price is used as the fair value; and, (2) for those securities which have not traded as of the date of the consolidated balance sheet, the fair value was determined by broker price indications of similar or same securities.

Investment Securities

Securities available for sale are valued on a recurring basis at quoted market prices where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable securities. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange and The NASDAQ Stock Market. Level 2 securities include mortgage-backed securities and debentures issued by government sponsored entities, municipal bonds and corporate debt securities, or U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Securities held to maturity are valued at quoted market prices or dealer quotes similar to securities available for sale. The carrying value of FHLB and FRB stock approximates fair value based on the redemption provisions.

Mortgage Loans Held for Sale

Mortgage loans held for sale are carried at fair value with changes in fair value recognized in current period earnings. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustments for mortgage loans held for sale are recurring Level 2.

Loans

We do not record loans at fair value on a recurring basis. However, from time to time, a loan may be individually evaluated for expected credit losses if it no longer shares similar risk characteristics with other pooled loans. Once a loan is identified as and individually evaluated loan, Management measures expected credit losses using estimated fair value methodologies. The fair value of the individually evaluated loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Those individually evaluated loans not requiring an ACL represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. At December 31, 2021, approximately 55% of the individually evaluated loans were evaluated based on the fair value of the collateral because such loans were considered collateral dependent. Individually evaluated loans, where an allowance is established based on the fair value of collateral; require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, we consider the impaired loan as nonrecurring Level 2. When an appraised value is not available or Management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, we consider the individually evaluated loan as nonrecurring Level 3.

​

Other Real Estate Owned (“OREO”)

OREO, consisting of properties obtained through foreclosure or in satisfaction of loans, is typically reported at fair value, determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, and adjusted for estimated selling costs (Level 2). However, OREO is considered Level 3 in the fair value hierarchy because Management has qualitatively applied a discount due to the size, supply of inventory, and the incremental discounts applied to the appraisals. Management also considers other factors, including changes in absorption rates, length of time the property has been on the market and anticipated sales values, which have resulted in adjustments to the collateral value estimates indicated in certain appraisals. At the time of foreclosure, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the ACL. Gains or losses on sale and generally any subsequent adjustments to the value are recorded as a component of OREO Expense and Loan Related Expense in the Consolidated Statements of Income.

Bank Property Held for Sale

​

Bank property held for sale consists of locations that Management has identified as no longer needed and reclassified from bank premises. These properties are typically reported at fair value, determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, and adjusted for estimated selling costs (Level 2). However, bank property held for sale is considered Level 3 in the fair value hierarchy because Management has qualitatively applied a discount due to the size, supply of inventory, restrictions and the incremental discounts applied to the appraisals. Management also considers other factors, including changes in absorption rates, length of time the property has been on the market and anticipated sales values, which have resulted in adjustments to the collateral value estimates indicated in certain appraisals. At the time a property is identified as held for sale, any excess of the book balance over the fair value of the real estate is treated as a charge against earnings. Gains or losses on sale and generally any subsequent write-downs to the value are recorded as a component in Other Expense in the Consolidated Statements of Income.

​

Derivative Financial Instruments

Fair value is estimated using pricing models of derivatives with similar characteristics or discounted cash flow models where future floating cash flows are projected and discounted back; and accordingly, these derivatives are classified within Level 2 of the fair value hierarchy. See Note 28—Derivative Financial Instruments for additional information.

F-68

Table of Contents

Mortgage servicing rights (“MSRs”)

The estimated fair value of MSRs is obtained through an independent derivatives dealer analysis of future cash flows. The evaluation utilizes assumptions market participants would use in determining fair value including market discount rates, prepayment speeds, servicing income, servicing costs, default rates and other market driven data, as well as the market’s perception of future interest rate movements. MSRs are classified as Level 3.

Changes in Level 3 Fair Value Measurements

When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses below include changes in fair value due in part to observable factors that are part of the valuation methodology.

There were no changes in hierarchy classifications of Level 3 assets or liabilities for the year ended December 31, 2021. A reconciliation of the beginning and ending balances of Level 3 assets and liabilities recorded at fair value on a recurring basis for the years ended December 31, 2021 and 2020 is as follows:

Fair Value of Financial Instruments

We used the following methods and assumptions in estimating our fair value disclosures for financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those models are significantly affected by the assumptions used, including the discount rates and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The use of different methodologies may have a material effect on the estimated fair value amounts. The fair value estimates presented herein are based on pertinent information available to Management as of December 31, 2021 and 2020. Such amounts have not been revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash and Cash Equivalents—The carrying amount is a reasonable estimate of fair value.

Trading Securities — The fair values of trading securities are determined as follows: (1) for those securities that have traded prior to the date of the consolidated balance sheet but have not settled (date of sale) until after such date, the sales price is used as the fair value; and, (2) for those securities which have not traded as of the date of the consolidated balance sheet, the fair value was determined by broker price indications of similar or same securities.

I nvestment Securities—Securities available for sale are valued at quoted market prices or dealer quotes. Securities held to maturity are valued at quoted market prices or dealer quotes similar to securities available for sale. The carrying value of FHLB and FRB stock approximates fair value based on the redemption provisions. The carrying value of our investment in unconsolidated subsidiaries approximates fair value. See Note 3—Investment Securities for additional information, as well as page F-67 regarding fair value.

Loans held for sale — The fair values disclosed for loans held for sale are based on commitments from investors for loans with similar characteristics.

​

Loans — The fair value of loans is based on an exit price. To estimate an exit price, all loans (fixed and variable) are being valued with a discounted cash flow analyses for loans that includes our estimate of future credit losses expected to be incurred over the life of the loans. Fair values for certain mortgage loans (e.g., one-to-four family residential) and other consumer loans are estimated using discounted cash flow analyses based on our current rates offered for new loans of the same type, structure and credit quality. Fair values for other loans (e.g., commercial real estate and investment property mortgage loans, commercial and industrial loans) are estimated using discounted cash flow analyses-using interest rates we currently offer for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using a discounted cash flow analysis.

​

Deposit Liabilities—The fair values disclosed for demand deposits (e.g., interest and non-interest bearing checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts, and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Table of Contents

Federal Funds Purchased and Securities Sold Under Agreements to Repurchase—The carrying amount of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings maturing within ninety days approximate their fair values.

Other Borrowings—The fair value of other borrowings is estimated using discounted cash flow analysis on our current incremental borrowing rates for similar types of instruments.

Accrued Interest—The carrying amounts of accrued interest approximate fair value.

Derivative Financial Instruments—The fair value of derivative financial instruments (including interest rate swaps) is estimated using pricing models of derivatives with similar characteristics or discounted cash flow models where future floating cash flows are projected and discounted back.

Commitments to Extend Credit, Standby Letters of Credit and Financial Guarantees—The fair values of commitments to extend credit are estimated taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair values of guarantees and letters of credit are based on fees currently charged for similar agreements or on the estimated costs to terminate them or otherwise settle the obligations with the counterparties at the reporting date.

The estimated fair value, and related carrying amount, of the Company’s financial instruments are as follows:

Note 26—Regulatory Matters

The Company is subject to regulations with respect to certain risk-based capital ratios. These risk-based capital ratios measure the relationship of capital to a combination of balance sheet and off-balance sheet risks. The values of both balance sheet and off-balance sheet items are adjusted based on the rules to reflect categorical credit risk. In addition to the risk-based capital ratios, the regulatory agencies have also established a leverage ratio for assessing capital adequacy. The leverage ratio is equal to Tier 1 capital divided by total average consolidated on-balance sheet assets (minus amounts deducted from Tier 1 capital). The leverage ratio does not involve assigning risk weights to assets.

​

Under current regulations, the Company and the Bank are subject to a minimum ratio of common equity Tier 1 capital (“CET1”) to risk-weighted assets of 4.5%. and a minimum required ratio of Tier 1 capital to risk-weighted assets of 6%. The minimum required leverage ratio is 4%. The minimum required total capital to risk-weighted assets ratio is 8%.

​

In order to avoid restrictions on capital distributions and discretionary bonus payments to executives, under the new rules a covered banking organization is also required to maintain a “capital conservation buffer” in addition to its minimum risk-based capital requirements. This buffer is required to consist solely of CET1, and the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital). The capital conservation buffer became fully phased-in on January 1, 2019 and consists of an additional amount of Tier 1 common equity equal to 2.5% of risk-weighted assets.

​

The Bank is also subject to the regulatory framework for prompt corrective action, which identifies five capital categories for insured depository institutions (well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) and is based on specified thresholds for each of the three risk-based regulatory capital ratios (CET1, Tier 1 capital and total capital) and for the leverage ratio.

​

The following table presents actual and required capital ratios as of December 31, 2021 and December 31, 2020 for the Company and the Bank under the current capital rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations.

As of December 31, 2021 and 2020, the capital ratios of the Company and the Bank were well in excess of the minimum regulatory requirements and exceeded the thresholds for the “well capitalized” regulatory classification.

​

In June 2016, the FASB issued ASU No. 2016-13 which required an entity to utilize a new impairment model

F-73

Table of Contents

known as the CECL model to estimate its lifetime “expected credit loss.” This standard was adopted and became effective on January 1, 2020 and the Company applied the provisions of the standard using the modified retrospective method as a cumulative-effect adjustment to retained earnings. Related to the implementation of ASU 2016-13, we recorded additional allowance for credit losses for loans of $54.4 million, deferred tax assets of $12.6 million, an additional reserve for unfunded commitments of $6.4 million and an adjustment to retained earnings of $44.8 million. Instead of recognizing the effects on regulatory capital from ASU 2016-13 at adoption, the Company initially elected the option for recognizing the adoption date effects on the Company’s regulatory capital calculations over a three-year phase-in. In March 2020, in response to the COVID-19 pandemic, the regulatory agencies provided an additional transitional method option of a two-year deferral for the start of the three-year phase-in of the recognition of the adoption date effects of ASU 2016-13 along with an option to defer the current impact on regulatory capital calculations of ASU 2016-13 during the first two years (“five-year method”). Under this five-year method, the Company would recognize an estimate of the previous incurred loss method for determining the allowance for credit losses in regulatory capital calculations and the difference from the CECL method would be deferred for two years. After two years, the effects from adoption date and the deferral difference from the first two years of applying CECL would be phased-in over three years using the straight-line method. The regulatory rules provide a one-time opportunity at the end of the first quarter of 2020 for covered banking organizations to choose its transition option for CECL. The Company chose the five-year method and is deferring the recognition of the effects from adoption date and the CECL difference from the first two years of application.

Cash Flow Hedges of Interest Rate Risk

The Company is exposed to interest rate risk in the course of its business operations and manages a portion of this risk through the use of derivative financial instruments, in the form of interest rate swaps. The Company accounts for interest rate swaps that are classified as a cash flow hedges in accordance with FASB ASC 815, Derivatives and Hedging, which requires that all derivatives be recognized as assets or liabilities on the balance sheet at fair value. We had no cash flow hedges as of December 31, 2021 and 2020. For more information regarding the fair value of the Company’s derivative financial instruments, see Note 25—Fair Value, to these financial statements.

During 2020 the Company utilized interest rate swap agreements to manage interest rate risk related to funding through short term FHLB advances. During the fourth quarter of 2020, the Company made the decision to repay the FHLB advances and terminate the interest rate swap agreements due to the current low interest rate environment and

the expectation that interest rates will remain low during the average life of these interest rate swaps. As a result, in December 2020, the Company recorded through earnings termination costs of $40.8 million related to the interest rate swaps which included $2.0 million in interest expense on the interest rate swap hedges.

For derivatives designated as hedging exposure to variable cash flows of a forecasted transaction (cash flow hedge), the derivative’s entire gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. For derivatives that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately. Historically, for designated hedging relationships, we have had a third-party perform retrospective and prospective effectiveness testing on a quarterly basis using quantitative methods to determine if the hedge is still highly effective. Hedge accounting ceases on transactions that are no longer deemed highly effective, or for which the derivative has been terminated or de-designated.

The Company did not maintain any cash flow hedges on the balance sheet throughout the year ended December 31, 2021. The Company recognized an after-tax unrealized gain on its cash flow hedges in other comprehensive income of $10.8 million for the year ended December 31, 2020. During 2020, at the time of the termination of the cash flow hedges, the Company reclassified into current earnings the unrealized loss on the cash flow hedge of $38.8 million ($30.3 million after-tax). There was no ineffectiveness in the cash flow hedges during the year ended December 31, 2020. (See Note 15—Accumulated Other Comprehensive Income (Loss) for activity in accumulated comprehensive income (loss) and the amounts reclassified into earnings related the cash flow hedges.)

Credit risk related to the derivative arises when amounts receivable from the counterparty (derivatives dealer) exceed those payable. We control the risk of loss by only transacting with derivatives dealers that are national market makers whose credit ratings are strong. Each party to the interest rate swap is required to provide collateral in the form of cash or securities to the counterparty when the counterparty’s exposure to a mark-to-market replacement value exceeds certain negotiated limits. These limits are typically based on current credit ratings and vary with ratings changes. With the Company not maintaining any cash flow hedges at December 31, 2021 and 2020, there was no collateral pledged.

Balance Sheet Fair Value Hedge

​

As of December 31, 2021 and 2020, the Company maintained loan swaps, with an aggregate notional amount of $15.7 million and $16.4 million, respectively, accounted for as a fair value hedge in accordance with ASC 815, Derivatives and Hedgin g. This derivative protects the company from interest rate risk caused by changes in interest rates in relation to a certain designated fixed rate loan. The derivative converts the fixed rate loan to a floating rate. Settlement occurs in any given period where there is a difference in the stated fixed rate and variable rate. The fair value of this hedge is recorded in other assets or in other liabilities. All changes in fair value are recorded through earnings as noninterest income. There was no gain or loss recorded on this derivative in 2021 or 2020.

Non-designated Hedges of Interest Rate Risk

​

Customer Swaps

​

The Company maintains interest rate swap contracts with customers that are classified as non-designated hedges and are not speculative in nature. These agreements are designed to convert customer’s variable rate loans with the Company to fixed rate. These interest rate swaps are executed with loan customers to facilitate a respective risk management strategy and allow the customer to pay a fixed rate of interest to the Company. These interest rate swaps are simultaneously hedged by executing offsetting interest rate swaps with unrelated market counterparties to minimize the net risk exposure to the Company resulting from the transactions and allow the Company to receive a variable rate of interest. The interest rate swaps pay and receive interest based on a floating rate based on one month LIBOR plus credit spread, with payments being calculated on the notional amount. The Company is in process of implementing a plan to transition these interest rate swap contracts to a reference rate other than LIBOR. For Discussion related to Reference Rate Reform, please refer to Issued But Not Yet Adopted Accounting Standards within Note 1—Summary of Significant Accounting Policies. The interest rate swaps are settled monthly with varying maturities.

​

As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of

F-76

Table of Contents

December 31, 2021 and 2020, the interest rate swaps had an aggregate notional amount of approximately $20.8 billion and $18.6 billion, respectively. At December 31, 2021, the fair value of the interest rate swap derivatives was recorded in other assets at $408.8 million and other liabilities at $408.8 million with a net liability position of $5,000. At December 31, 2020, the fair value of the interest rate swap derivatives was recorded in other assets at $802.8 million and other liabilities at $802.7 million for a net asset position of $17,000. All changes in fair value are recorded through earnings as noninterest income. As of December 31, 2021, we provided $347.6 million of cash collateral on the counterparty swaps which is included in cash and cash equivalents on the balance sheet as deposits in other financial institutions (restricted cash). The Company also provided $348.8 million in investment securities at market value as collateral on the counterparty swaps which is included in investment securities.

​

Foreign Exchange

​

The Company also enters into foreign exchange contracts with customers to accommodate their need to convert certain foreign currencies into U.S. Dollars. To offset the foreign exchange risk, the Company has entered into substantially identical agreements with an unrelated market counterparty to hedge these foreign exchange contracts. At December 31, 2021 and 2020, there were no outstanding contracts or agreements related to foreign currency. If there were foreign currency contracts outstanding at December 31, 2021 and 2020, the fair value of these contracts would be included in other assets and other liabilities in the accompanying balance sheet. All changes in fair value are recorded as other noninterest income. There was no gain or loss recorded related to the foreign exchange derivative for the years ended December 31, 2021 or 2020.

Mortgage Banking

The Company also has derivatives contracts that are not classified as accounting hedges to mitigate risks related to its mortgage banking activities. These instruments may include financial forwards, futures contracts, and options written and purchased, which are used to hedge mortgage servicing rights; while forward sales commitments are typically used to hedge the mortgage pipeline. Such instruments derive their cash flows, and therefore their values, by reference to an underlying instrument, index or referenced interest rate. The Company does not elect hedge accounting treatment for any of these derivative instruments and as a result, changes in fair value of the instruments (both gains and losses) are recorded in the Company’s consolidated statements of income in mortgage banking income.

Mortgage Servicing Rights

Derivatives contracts related to mortgage servicing rights are used to help offset changes in fair value and are written in amounts referred to as notional amounts. Notional amounts provide a basis for calculating payments between counterparties but do not represent amounts to be exchanged between the parties, and are not a measure of financial risk. On December 31, 2021 and 2020, the Company had derivative financial instruments outstanding with notional amounts totaling $205.0 million and $149.0 million related to mortgage servicing rights, respectively. The estimated net fair value of the open contracts related to the mortgage servicing rights was recorded as a gain of $1.2 million at December 31, 2021 compared to a gain of $119,000 at December 31, 2020.

The following table presents the Company’s notional value of forward sale commitments and the fair value of those obligations along with the fair value of the mortgage loan pipeline.

Note 29—Loan Servicing, Mortgage Origination, and Loans Held for Sale

The portfolio of residential mortgages serviced for others, which are not included in the accompanying balance sheets, was $6.1 billion and $5.1 billion at December 31, 2021 and 2020, respectively. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts and disbursing payments to investors. The amounts of contractually specified servicing fees earned by the Company during the years ended December 31,

F-77

Table of Contents

2021 and 2020 were $14.1 million and $9.8 million, respectively. Servicing fees are recorded in mortgage banking income in the Company’s consolidated statements of income.

At December 31, 2021 and 2020, MSRs were $65.6 million and $43.8 million, respectively, on the Company’s consolidated balance sheet. MSRs are recorded at fair value with changes in fair value recorded as a component of mortgage banking income in the Consolidated Statements of Income. The market value adjustments related to MSRs recorded in mortgage banking income for the years ended December 31, 2021 and 2020 were gain of $9.9 million and loss of $7.4 million, respectively. The Company has used various free standing derivative instruments to mitigate the income statement effect of changes in fair value due to changes in market value adjustments and to changes in valuation inputs and assumptions related to MSRs.

The following table presents the changes in the fair value of MSRs and its offsetting hedge.

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Net effect on statements of income | ​ | $ | (9,825) | ​ | $ | (6,037) | ​ | $ | (7,598) | ​

​

The fair value of MSRs is highly sensitive to changes in assumptions and fair value is determined by estimating the present value of the asset’s future cash flows utilizing market-based prepayment rates, discount rates and other assumptions validated through comparison to trade information, industry surveys and with the use of independent third-party appraisals. Changes in prepayment speed assumptions have the most significant impact on the fair value of MSRs. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of the MSR. Measurement of fair value is limited to the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different time. See Note 25—Fair Value for additional information regarding fair value.

The characteristics and sensitivity analysis of the MSRs are included in the following table.

​

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the changes in assumptions to fair value may not be linear. Also, in this table, the effects of an adverse variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumptions, while in reality, changes in one factor may result in changing another, which may magnify or contract the effect of the change.

Custodial escrow balances maintained in connection with the loan servicing were $29.6 million and $26.6 million, respectively, at December 31, 2021 and 2020.

Whole loan sales were $3.1 billion and $3.2 billion, respectively, for the years ended December 31, 2021 and 2020, of which $2.4 billion and $2.7 billion, respectively, or 76.8% and 85.1%, respectively, were sold with the servicing rights retained by the Company.

Loans held for sale have historically been comprised of residential mortgage loans awaiting sale in the secondary market, which generally settle in 15 to 45 days. At December 31, 2021, loans held for sale were $191.7 million, compared with $290.5 million at December 31, 2020.

Note 30—Investments in Qualified Affordable Housing Projects

The Company has investments in qualified affordable housing projects (“QAHPs”) that provide low income housing tax credits and operating loss benefits over an extended period. The tax credits and the operating loss tax benefits that are generated by each of the properties are expected to exceed the total value of the investment made by the Company. For the year ended December 31, 2021, tax credits and other tax benefits of $13.7 million and amortization of $9.9 million were recorded. For the year ended December 31, 2020, the Company recorded tax credits and other tax benefits of $11.2 million and amortization of $12.9 million. At December 31, 2021 and 2020, the Company’s carrying value of QAHPs was $99.5 million and $105.6 million, respectively, with an original investment of $140.8 million and $137.1 million respectively. The Company has $15.6 million and $42.7 million in remaining funding obligations related to these QAHPs recorded in liabilities at December 31, 2021 and 2020, respectively. None of the original investment will be repaid. The investment in QAHPs is being accounted for using the equity method.
