NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Table dollars in thousands, except share and per share data) (Unaudited)

Note 1—Basis of Presentation

These unaudited interim condensed consolidated financial statements include the accounts of Byline Bancorp, Inc., a Delaware corporation (the “Company,” “Byline,” “we,” “us,” “our”), a bank holding company whose principal activity is the ownership and management of its Illinois state chartered subsidiary bank, Byline Bank (the “Bank”), based in Chicago, Illinois.

These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In preparing these financial statements, the Company has evaluated events and transactions subsequent to September 30, 2020 for potential recognition or disclosure. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information in footnote disclosures normally included in financial statements prepared in accordance with GAAP has been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Consolidated Financial Statements for the years ended December 31, 2019, 2018, and 2017.

In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 855, “Subsequent Events,” the Company’s management has evaluated subsequent events for potential recognition or disclosure through the date of the issuance of these condensed consolidated financial statements.

The Company has one reportable segment. The Company’s chief operating decision maker evaluates the operations of the Company using consolidated information for purposes of allocating resources and assessing performance. Therefore, segments disclosures are not required.

No subsequent events were identified that would have required a change to the condensed consolidated financial statements or disclosure in the notes to the condensed consolidated financial statements.

Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications did not result in any changes to previously reported net income or stockholders’ equity.

Note 2—Accounting Pronouncements Recently Adopted or Issued

The following reflect recent accounting pronouncements that have been adopted or are pending adoption by the Company. As the Company qualifies as an emerging growth company and has elected the extended transition period for complying with new or revised accounting pronouncements, it is not subject to new or revised accounting standards applicable to public companies during the extended transition period. The accounting pronouncements pending adoption below reflect effective dates for the Company as an emerging growth company with the extended transition period.

Adopted Accounting Pronouncement

Nonrefundable Fees and Other Costs (Subtopic 310‑20)—In March 2017, FASB issued ASU No. 2017‑08, Receivables—Nonrefundable Fees and Other Costs. The amendments in the ASU shorten the amortization period for certain callable debt securities held at a premium at the earliest call date. Under current GAAP, the Company amortizes the premium as an adjustment of yield over the contractual life of the instrument. As a result, upon exercise of a call on a callable debt security held at a premium, the unamortized premium is charged to earnings. The ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. However, the amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. The Company is required to apply the amendments on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Given our emerging growth status, t he Company adopted these amendments on January 1, 2020 in conjunction with ASU No. 2017-08, which did not have a material impact on the Company’s Consolidated Financial Statements.

Issued Accounting Pronouncements Pending Adoption

Leases (Topic 842)—In February 2016, FASB issued ASU No. 2016‑02, Leases. The amendments in this ASU require lessees to recognize the following for all leases (with the exception of short-term) at the commencement date: a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The amendments in this ASU leave lessor accounting largely unchanged, although certain targeted improvements were made to align lessor accounting with the lessee accounting model. This ASU simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is evaluating the new guidance and its impact on the Company’s Consolidated Statements of Operations and Consolidated Statements of Financial Condition. In November 2019, FASB issued ASU No. 2019-10, Effective Dates, which delays the effective date of this ASU for entities not classified as Public Business Entities (PBEs). Our status as an emerging growth company makes us eligible for this deferral. Assuming the Company remains an emerging growth company, the new authoritative guidance is effective for fiscal years beginning after December 15, 2020, and interim periods with fiscal years beginning after December 15, 2021. The Company expects an increase in assets and liabilities as a result of recognizing additional right-of-use assets and liabilities under lease contracts in which the Company is lessee. While the Company has not quantified the impact of this ASU on its direct financing lease portfolio, it does not expect a material change in its accounting for the initial direct costs related to these leases.

Financial Instruments—Credit Losses (Topic 326)—In June 2016, FASB issued ASU No. 2016‑13, Measurement of Credit Losses on Financial Instruments. Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU require a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendments in this ASU broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss, which will be more useful to users of the financial statements. In November 2019, FASB issued ASU No. 2019-10, Effective Dates, which delays the effective date of the ASU for entities not classified as PBEs. Assuming the Company remains an emerging growth company, the new authoritative guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is in the process of implementation and determining the impact that this ASU will have on the Company’s Consolidated Financial Statements.

Income Taxes (Topic 740)—In December 2019, FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes. The amendments in the ASU simplify the accounting for income taxes by removing the following: the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items; the exception to the requirement to or not to recognize a deferred tax liability for a foreign entity when it becomes an equity method investment or it becomes a subsidiary, respectively; and the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in the ASU changes current authoritative guidance by requiring the recognition of franchise 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; requiring an evaluation when a step up in the tax basis of goodwill should be considered part the of business combination; specifying that it is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements; and requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the

enactment date. The amendments are effective for annual periods beginning after December 15, 2021, and interim periods within annual periods beginning after December 15, 2022. Early adoption is permitted. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2022. The Company is currently evaluating the provisions of ASU No. 2019-12 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements.

Reference Rate Reform (Topic 848)—In March 2020, FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in the ASU provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in the ASU provide optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. The amendments in the ASU will be in effect for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the provisions of ASU No. 2020-04 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements.

Note 3—Acquisition

On April 30, 2019, the Company acquired all of the outstanding common stock of Oak Park River Forest Bankshares, Inc. (“Oak Park River Forest”) and its subsidiary pursuant to an Agreement and Plan of Merger, dated as of October 17, 2018 (the “OPRF Merger Agreement”). Oak Park River Forest operated one wholly owned subsidiary, Community Bank of Oak Park River Forest. Oak Park River Forest was merged with and into Byline. As a result of the merger, Oak Park River Forest’s subsidiary bank, Community Bank of Oak Park River Forest, was merged with and into Byline Bank, with Byline Bank as the surviving bank. The acquisition improves the Company’s footprint in the Chicagoland market, diversifies its commercial banking business, and strengthens the core deposit base.

At the effective time of the merger (the “OPRF Effective Time”), each share of Oak Park River Forest’s common stock was converted into the right to receive: (1) 7.9321 shares of Byline’s common stock, and (2) an amount in cash equal to $6.2 million divided by the number of outstanding shares of Oak Park River Forest common stock as of the closing date, with cash paid in lieu of any fractional shares. The per share cash consideration was based on the total $6.2 million divided by the outstanding shares of Oak Park River Forest common stock, or $33.375 per outstanding share. Based on the closing price of the Company’s common stock of $20.02, as reported by the New York Stock Exchange, and 1,464,558 shares of common stock issued with respect to the outstanding shares of Oak Park River Forest common stock, the stock consideration was valued at $29.3 million. Options to acquire 35,870 shares of Oak Park River Forest common stock that were outstanding at the OPRF Effective Time were cancelled, at the option holders election, in exchange for a cash payment in accordance with the OPRF Merger agreement of $4.2 million, to be paid after the closing date. The value of the total merger consideration at closing was $35.5 million before issuance costs of $585,000.

The transaction resulted in goodwill of $20.2 million, which is nondeductible for tax purposes, as this acquisition was a nontaxable transaction. Goodwill represents the premium paid over the fair value of the net tangible and intangible assets acquired and reflects related synergies expected from the combined operations. The Company incurred Oak Park River Forest merger-related expenses, including acquisition advisory expenses, of $2.3 million for the year ended December 31, 2019, including $2.3 million for the nine months ended September 30, 2019. The Company incurred merger-related income of $135,000 for the three months ended September 30, 2019, resulting from a legal fee credit. Core system conversion expenses were $2.0 million related to the Oak Park River Forest acquisition for the year ended December 31, 2019. Core system conversion expenses of $1.2 million and $1.9 million related to the Oak Park River Forest acquisition were recognized during the three and nine months ended September 30, 2019, respectively. These expenses are reflected in non-interest expense on the Consolidated Statements of Operations.

The acquisition of Oak Park River Forest was accounted for using the acquisition method of accounting in accordance with ASC Topic 805. Assets acquired, liabilities assumed and consideration exchanged were recorded at their respective acquisition date fair values. Determining the fair value of assets and liabilities involves significant judgment regarding methods and assumptions used to calculate estimated fair values. The fair value adjustments associated with this transaction were finalized during the first quarter of 2020.

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. The Company evaluated the securities that had an unrealized loss for other than temporary impairment and determined all declines in value to be temporary. There were 41 securities available-for-sale with unrealized losses at September 30, 2020. There were no securities held-to-maturity with unrealized losses at September 30, 2020. The Company anticipates full recovery of amortized cost with respect to these securities by maturity, or sooner, in the event of a more favorable market interest rate environment. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The proceeds from all sales of securities available-for-sale, and the associated gains and losses, for the three and nine months ended September 30, 2020 and 2019 are listed below:

There were $1.0 million and $2.4 million in net gains reclassified from accumulated other comprehensive income into earnings for the three and nine months ended September 30, 2020, respectively. There were $178,000 and $1.2 million in net gains reclassified from accumulated other comprehensive income into earnings for the three and nine months ended September 30, 2019, respectively.

Securities posted as collateral were $994.1 million and $552.4 million at September 30, 2020 and December 31, 2019, respectively, of which carrying amounts of $407.9 million and $301.1 million were pledged at September 30, 2020 and December 31, 2019, respectively. At September 30, 2020 and December 31, 2019, of those pledged, the carrying amounts of securities pledged as collateral for public fund deposits were $346.4 million and $240.4 million, respectively, and for customer repurchase agreements of $56.4 million and $55.7 million, respectively. At September 30, 2020 and December 31, 2019, there were no securities pledged for advances from the Federal Home Loan Bank. Other securities were pledged for derivative positions, letters of credit and for purposes required or permitted by law. At September 30, 2020 and December 31, 2019, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity.

Total loans and leases consist of originated loans and leases, acquired impaired loans and acquired non-impaired loans and leases. At September 30, 2020 and December 31, 2019, total loans and leases included the guaranteed amount of U.S. government guaranteed loans of $765.7 million and $119.8 million, respectively. At September 30, 2020 and December 31, 2019, the discount on the unguaranteed portion of U.S. government guaranteed loans was $25.7 million and $23.1 million, respectively, which are included in total loans and leases. At September 30, 2020 and December 31, 2019, installment and other loans included overdraft deposits of $301,000 and $852,000, respectively, which were reclassified as loans. At September 30, 2020 and December 31, 2019, loans and leases and loans held for sale pledged as security for borrowings were $2.4 billion and $1.8 billion, respectively.

The minimum annual lease payments for lease financing receivables as of September 30, 2020 are summarized as follows:

|  | Minimum Lease Payments |
2020 |  | $ | 18,955 |
2021 |  |  | 73,625 |

Total |  | $ | 209,606 |

Originated loans and leases represent originations excluding loans initially acquired in a business combination. However, once an acquired non-impaired loan reaches its maturity date, and is re-underwritten and renewed, it is internally classified as an originated loan. Acquired impaired loans are loans acquired from a business combination with evidence of credit quality deterioration and are accounted for under ASC Topic 310-30. Acquired non-impaired loans and leases represent loans and leases acquired from a business combination without more than insignificant evidence of credit quality deterioration and are accounted for under ASC Topic 310-20. Acquired leases and revolving loans having evidence of credit quality deterioration do not qualify to be accounted for as acquired impaired loans and are accounted for under ASC Topic 310-20. The following tables summarize the balances for each respective loan and lease category as of September 30, 2020 and December 31, 2019:

The Company increased the allowance for loan and lease losses by $10.0 million and $29.3 million for the three and nine months ended September 30, 2020, respectively, and by $453,000 and $6.4 million for the three and nine months ended September 30, 2019, respectively. For acquired impaired loans, the Company increased the allowance for loan and lease losses by $295,000 and $2.3 million for the three and nine months ended September 30, 2020, respectively. The Company decreased the allowance for loan and lease losses by $480,000 and increased them by $260,000 for the three and nine months ended September 30, 2019, respectively.

For loans individually evaluated for impairment, the Company increased the allowance for loan and lease losses by $768,000 and $4.1 million for the three and nine months ended September 30, 2020, respectively, and by $276,000 and $2.9 million for the three and nine months ended September 30, 2019, respectively.

An allowance for loan and lease loss allocation has not been made for Paycheck Protection Program (“PPP”) loans as the loans have a 100% SBA guarantee. On a quarterly basis, the Company assesses the collectability of its government guarantee using historical experience.

The following tables summarize the recorded investment, unpaid principal balance, and related allowance for loans and leases considered impaired as of September 30, 2020 and December 31, 2019, which exclude acquired impaired loans. For purposes of these tables, the unpaid principal balance represents the outstanding contractual balance. Impaired loans include loans that are individually evaluated for impairment as well as troubled debt restructurings for all loan categories. The sum of non-accrual loans and loans past due 90 days still on accrual will differ from the total impaired loan amount.

Loan servicing revenue totaled $2.9 million and $2.7 million for the three months ended September 30, 2020 and 2019, respectively. Loan servicing revenue totaled $8.7 million and $7.9 million for the nine months ended September 30, 2020 and 2019, respectively. Loan servicing asset revaluation, which represents the changes in fair value of servicing assets, resulted in an upward valuation of $1.1 million for three months ended September 30, 2020 and a downward valuation of $1.6 million for three months ended September 30, 2019, respectively. Loan servicing asset revaluation resulted in downward valuations of $2.7 million and $4.1 million for the nine months ended September 30, 2020 and 2019, respectively.

The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in secondary market premiums contribute to the change in fair value of servicing rights while prepayment speed assumptions have the most significant impact on the fair value of servicing rights.

Generally, as interest rates rise on variable rate loans, loan prepayments increase due to an increase in refinance activity, which may result in a decrease in the fair value of servicing assets. Measurement of fair value is limited to the conditions existing and the assumptions used as of a particular point in time, and those assumptions may change over time. Refer to Note 15—Fair Value Measurement for further details.

Note 10—Income Taxes

The Company uses an estimated annual effective tax rate method in computing its interim tax provision. This effective tax rate is based on forecasted annual pre-tax income, permanent tax differences and statutory tax rates.

The effective tax rate for the nine months ended September 30, 2020 and 2019 was 28.5% and 27.7%, respectively. The Company recorded discrete income tax provision of $231,000 and a benefit of $64,000 related to the exercise of stock options and vesting of restricted shares for the nine months ended September 30, 2020 and 2019, respectively.

Net deferred tax assets decreased to $35.9 million at September 30, 2020 compared to $38.3 million at December 31, 2019. The net decrease in the total net deferred tax assets recorded as of September 30, 2020 was a result of an increase in unrealized gains on available-for-sale securities and decreases in net operating losses and tax credits, partially offset by an increase in allowance for loan and lease losses, and unearned processing fees related to PPP originations.

On June 26, 2020, the Company issued $50.0 million in 6.00% fixed-to-floating subordinated notes that mature on July 1, 2030. On August 3, 2020, the Company issued an additional $25.0 million as part of the same series of notes as the $50.0 million issued on June 26, 2020. The subordinated notes bear a fixed interest rate of 6.00% until July 1, 2025 and a floating interest rate equal to a benchmark rate, which is expected to be three-month Secured Overnight Financing Rate plus 588 basis points thereafter until maturity. These transactions resulted in debt issuance costs of approximately $1.7 million that will be amortized over 10 years.

As of September 30, 2020, the net liability outstanding of the subordinated notes was $73.3 million The Company may, at its option, redeem the notes, in whole or in part, on a semi-annual basis beginning on July 1, 2025, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required. The subordinated notes are intended to qualify as Tier 2 capital for regulatory capital purposes

In 2004, the Company’s predecessor, Metropolitan Bank Group, Inc., issued $35.0 million floating rate junior subordinated debentures to Metropolitan Statutory Trust 1, which was formed for the issuance of trust preferred securities. The debentures bear interest at three-month LIBOR plus 2.79% (3.03% and 4.69% at September 30, 2020 and December 31, 2019, respectively). Interest is payable quarterly. The Company has the right to redeem the debentures, in whole or in part, on any interest payment date on or after March 2009. Accrued interest payable was $43,000 and $71,000 as of September 30, 2020 and December 31, 2019, respectively.

As part of the Ridgestone acquisition, the Company assumed the obligations to RidgeStone Capital Trust I of $1.5 million in principal amount, which was formed for the issuance of trust preferred securities. Beginning on June 30, 2008, the interest rate reset to the five-year LIBOR plus 3.50% (6.38% at December 31, 2019), which was in effect until June 30, 2023 and updated every five years. Interest was paid on a quarterly basis. The Company had the right to redeem the debentures, in whole or in part, on any interest payment date on or after June 30, 2008. There was no accrued interest payable as of December 31, 2019. On February 25, 2020 the Company notified the trustee of RidgeStone Capital Trust I of its intent to redeem the debentures. On June 30, 2020, the Company redeemed the debentures, in whole and at the par value of $1.5 million and recognized a charge of $112,000 to non-interest income for the remaining discount.

The Company owns all of the common securities of each trust. The junior subordinated debentures qualify, and are treated as, Tier 1 regulatory capital of the Company subject to regulatory limitations. The trust preferred securities issued by each trust rank equally with the common securities in right of payment, except that if an event

For the nine months ended September 30, 2020 and 2019, the Company received $549,000 and $560,000, respectively, in sublease income. The total amount of minimum rentals to be received in the future on these subleases is approximately $808,000, and the leases have contractual lives extending through 2025. In addition to the above required lease payments, the Company has contractual obligations related primarily to information technology contracts and other maintenance contracts.

Commitments to extend credit—The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The contractual or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for funded instruments. The Company does not anticipate any material losses as a result of the commitments and letters of 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 amount does not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties).

Letters of credit are conditional commitments issued by the Company to guarantee to a third-party the performance of a customer. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 1.25% to 18.00% and maturities up to 2050. Variable rate loan commitments have interest rates ranging from 1.25% to 8.25% and maturities up to 2048.

Note 15—Fair Value Measurement

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. In addition, the Company has the ability to obtain fair values for markets that are not accessible.

These types of inputs create the following fair value hierarchy:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The Company’s own data used to develop unobservable inputs may be adjusted for market considerations when reasonably available.

The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to assets and liabilities.

The Company used the following methods and significant assumptions to estimate fair value for certain assets measured and carried at fair value on a recurring basis:

Securities available-for-sal e—The Company obtains fair value measurements from an independent pricing service. Management reviews the procedures used by the third party, including significant inputs used in the fair value calculations. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. When market quotes are not readily accessible or available, alternative approaches are utilized, such as matrix or model pricing.

The Company’s methodology for pricing non-rated bonds focuses on three distinct inputs: equivalent rating, yield and other pricing terms. To determine the rating for a given non-rated municipal bond, the Company references a publicly issued bond by the same issuer if available as well as other additional key metrics to support the credit worthiness. Typically, pricing for these types of bonds would require a higher yield than a similar rated bond from the same issuer. A reduction in price is applied to the rating obtained from the comparable bond, as the Company believes if liquidated, a non-rated bond would be valued less than a similar bond with a verifiable rating. The reduction applied by the Company is one notch lower (i.e. a “AA” rating for a comparable bond would be reduced to “AA-” for the Company’s valuation). In 2020 and 2019, all of the ratings derived by the Company were “BBB” or better with and without comparable bond proxies. The fair value measurement of municipal bonds is sensitive to the rating input, as a higher rating typically results in an increased valuation. The remaining pricing inputs used in the bond valuation are observable. Based on the rating determined, the Company obtains a corresponding current market yield curve available to market participants. Other terms including coupon, maturity date, redemption price, number of coupon payments per year, and accrual method are obtained from the individual bond term sheets.

Equity and other securities—The Company utilizes the same fair value measurement methodology for equity and other securities as detailed in the securities available-sale portfolio above.

Servicing assets—Fair value is based on a loan-by-loan basis taking into consideration the original term to maturity, the current age of the loan and the remaining term to maturity. The valuation methodology utilized for the servicing assets begins with generating estimated future cash flows for each servicing asset, based on their unique characteristics and market-based assumptions for prepayment speeds and costs to service. The present value of the future cash flows are then calculated utilizing market-based discount rate assumptions.

Derivative instruments—Interest rate derivatives are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. Derivative financial instruments are included in other assets and other liabilities in the Consolidated Statements of Financial Condition.

|  |  |  | Expected weighted average loan life |  | 0.1 - 8.6 years |  | 3.7 years |  |  | Increase

The Company used the following methods and significant assumptions to estimate fair value for certain assets measured and carried at fair value on a non-recurring basis:

Impaired loans (excluding acquired impaired loans)—Impaired loans, other than those existing on the date of a business acquisition, are primarily carried at the fair value of the underlying collateral, less estimated costs to sell, if the loan is collateral dependent. Valuations of impaired loans that are collateral dependent are supported by third party appraisals in accordance with the Bank’s credit policy. Other valuation methods include analysis of discounted cash flows, which measures the present value of expected future cash flows discounted at the loan’s effective interest rate. Impaired loans that are not collateral dependent are not material.

Assets held for sale—Assets held for sale consist of former branch locations and real estate previously purchased for expansion. Assets are considered held for sale when management has approved to sell the assets following a branch closure or other events. The properties are being actively marketed and transferred to assets held for sale based on the lower of carrying value or its fair value, less estimated costs to sell.

(Table dollars in thousands, except share and per share data) (Unaudited)

Other real estate owne d—Certain assets held within other real estate owned represent real estate or other collateral that has been adjusted to its estimated fair value, less cost to sell, as a result of transferring from the loan portfolio at the time of foreclosure or repossession and based on management’s periodic impairment evaluation. From time to time, non-recurring fair value adjustments to other real estate owned are recorded to reflect partial write-downs based on an observable market price or current appraised value of property.

Adjustments to fair value based on such non-recurring transactions generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment. The following tables summarize the Company’s assets that were measured at fair value on a non-recurring basis, excluding acquired impaired loans, as of September 30, 2020 and December 31, 2019:

The following methods and assumptions were used by the Company in estimating fair values of other assets and liabilities for disclosure purposes:

Cash and cash equivalents—For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Securities held-to-maturity—The Company obtains fair value measurements from an independent pricing service. Management reviews the procedures used by the third party, including significant inputs used in the fair value calculations. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. When market quotes are not readily accessible or available, alternative approaches are utilized, such as matrix or model pricing.

Restricted stock—The fair value has been determined to approximate cost.

Loans held for sale—The fair value of loans held for sale are based on quoted market prices, where available, and determined by discounted estimated cash flows using interest rates approximating the Company’s current origination rates for similar loans adjusted to reflect the inherent credit risk.

(Table dollars in thousands, except share and per share data) (Unaudited)

Loan and lease receivables, net—For certain variable rate loans that reprice frequently and with no significant changes in credit risk, fair value is estimated at carrying value. The fair value of other types of loans is estimated using an exit price notion. It is estimated by discounting f uture cash flows, using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Deposits—The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated by discounting future cash flows, using rates currently offered for deposits of similar remaining maturities.

Paycheck Protection Program Liquidity Facility—The carrying amount approximates fair value.

Federal Home Loan Bank advances—The fair value of FHLB advances is estimated by discounting the agreements based on maturities using rates currently offered for FHLB advances of similar remaining maturities adjusted for prepayment penalties that would be incurred if the borrowings were paid off on the measurement date.

Securities sold under agreements to repurchase—The carrying amount approximates fair value due to maturities of less than ninety days.

Subordinated notes—The fair value is based on available market prices.

Junior subordinated debentures—The fair value of junior subordinated debentures, in the form of trust preferred securities, is determined using rates currently available to the Company for debt with similar terms and remaining maturities.

Accrued interest receivable and payable—The carrying amount approximates fair value.

Commitments to extend credit and letters of credit—The fair values of these off-balance sheet commitments to extend credit and commercial and letters of credit are not considered practicable to estimate because of the lack of quoted market prices and the inability to estimate fair value without incurring excessive costs.

The estimated fair values of financial instruments not carried at fair value and levels within the fair value hierarchy are as follows:

Note 16—Derivative Instruments and Hedge Activities

As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company records derivative assets and derivative liabilities on the Consolidated Statements of Financial Condition within accrued interest receivable and other assets and accrued interest payable and other liabilities, respectively. The following tables present the fair value of the Company’s derivative financial instruments and classification on the Consolidated Statements of Financial Condition as of September 30, 2020 and December 31, 2019:

|  | September 30, 2020 |  |  | December 31, 2019 |

Interest rate swaps designated as cash flow hedges—There were no cash flow hedges outstanding at September 30, 2020 and December 31, 2019. In September 2019, the Company terminated $250.0 million interest rate swaps designated as cash flow hedges of interest payments associated with certain FHLB advances, which were executed to reduce interest rate risk in a declining rate environment. The transaction resulted in a net loss of $383,000, net of tax, which was the clean value at the termination date. As of September 30, 2020, the remaining balance in accumulated other comprehensive loss was $320,000, which is being amortized over the original life of the cash flow hedge. At September 30, 2020, the Company estimates $92,000 of the unrealized loss to be reclassified as an increase to interest expense during the next twelve months.

The following table reflects the net gains (losses) recorded in accumulated other comprehensive income (loss) and the Consolidated Statements of Operations relating to the cash flow derivative instruments for the nine months ended:

Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements and/or the Company has not elected to apply hedge accounting. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings.

Other interest rate derivatives— The Company also enters into derivative transactions through products with its commercial customers and simultaneously enters into an offsetting interest rate derivative transaction with third-parties. These transactions allow the Company's borrowers to effectively convert a variable rate loan into a fixed rate loan. The total combined notional amount was $373.8 million as of September 30, 2020 with maturities ranging from January 2022 to March 2030. The fair values of the interest rate derivative agreements are reflected in other assets and other liabilities with corresponding gains or losses reflected in non-interest income. During the three months ended September 30, 2020 and 2019, there were $41,000 and $170,000 of transaction fees, respectively, included in other non-interest income, related to these derivative instruments. During the nine months ended September 30, 2020 and 2019, there were $700,000 and $886,000 of transaction fees, respectively, included in other non-interest income, related to these derivative instruments.

These instruments are inherently subject to market risk and credit risk. Market risk is associated with changes in interest rates and credit risk relates to the Company’s risk of loss when the counterparty to a derivative contract fails to perform according to the terms of the agreement. Market and credit risks are managed and monitored as part of the Company’s overall asset-liability management process. The credit risk related to derivatives entered into with certain qualified borrowers is managed through the Company’s loan underwriting process. The Company’s loan underwriting process also approves the Bank’s swap counterparty used to mirror the borrowers’ swap. The Company has a bilateral agreement with each swap counterparty that provides that fluctuations in derivative values are to be fully collateralized with either cash or securities.

The following table reflects other interest rate derivatives as of September 30, 2020:

Notional amounts |  | $ | 373,782 |
Derivative assets fair value |  |  | 19,133 |
Derivative liabilities fair value |  |  | 20,307 |
Weighted average pay rates |  |  | 4.48 | %
Weighted average receive rates |  |  | 2.31 | %
Weighted average maturity |  | 6.1 years |

Other credit derivatives— The Company has entered into risk participation agreements with counterparty banks to assume a portion of the credit risk related to borrower transactions. The credit risk related to these other credit derivatives is managed through the Company’s loan underwriting process. The total notional amount was $8.7 million and $9.3 million as of September 30, 2020 and December 31, 2019, respectively. The fair value of the other credit derivatives are reflected in other liabilities with corresponding gains or losses reflected in non-interest income.

The Company has agreements with its derivative counterparties that contain a cross-default provision under which if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain derivative counterparties that contain a provision where if the Company fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations resulted in a net asset position.

The following table reflects amounts included in non-interest income in the Consolidated Statements of Operations relating to derivative instruments that are not designated in a hedging relationship for the three and nine months ended September 30, 2020 and 2019:

As of September 30, 2020, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $20.3 million. The Company has posted $20.9 collateral related to these agreements as of September 30, 2020. If the Company had breached any of these provisions at September 30, 2020, it could have been required to settle its obligations under the agreements at their termination value of $20.3 million. For purposes of this disclosure, the amount of posted collateral by the counterparties is limited to the amount offsetting the derivative asset and derivative liability.

Note 17 – Share-Based Compensation

In June 2017, the Company adopted the 2017 Omnibus Incentive Compensation Plan (the “Omnibus Plan”) in connection with our IPO. The Omnibus Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent rights and other equity-based, equity-related or cash-based awards. A total of 1,550,000 shares of our common stock have been reserved for issuance under the Omnibus Plan. As of September 30, 2020, there were 1,001,731 shares available for future grants under the Omnibus Plan.

On July 6, 2017, in conjunction with the completion of the IPO, the Company granted 58,900 restricted shares of the Company’s common stock to certain key employees, pursuant to the Omnibus Plan. These shares fully vested on July 6, 2020. A total of 11,898 restricted shares were also granted during the year ended December 31, 2017 in connection with the recruitment of employees. These restricted shares vest ratably over a four year period.

During 2018, the Company granted 131,157 shares of restricted common stock, par value $0.01 per share. Of this total, 101,559 restricted shares will vest ratably over four years on each anniversary of the grant date and 14,380 restricted shares will vest ratably over three years on each anniversary of the grant date, all subject to continued employment. A total of 4,053 restricted shares have vested.

In addition, 11,165 performance-based restricted shares were included in the 2018 grant. The number of shares which may be earned under the award is dependent upon the Company’s return on average assets over a three-year period ending December 31, 2020, measured in 2018 against the Company’s internal targets and for 2019 and 2020 against a peer group consisting of publicly-traded bank holding companies ranging in asset size from 50% to 200% of the Company’s total assets. Under the 2018 award, 25% of the shares will be earned at threshold performance, 100% will be earned at target and 50th percentile performance, and up to 125% of the shares with above target and 75th percentile performance. Any earned performance shares will vest on the third anniversary of the grant date.

In October 2014, the Company adopted the Byline Bancorp, Inc. Equity Incentive Plan (“BYB Plan”). The maximum number of shares available for grants under this plan was 2,476,122 shares. During 2016 and 2015, the Company granted options to purchase 212,400 and 1,634,568 shares, respectively; the Company did not grant any stock options during 2017. In June 2017, the Board of Directors terminated the BYB Plan and no future grants can be made under this plan. Options to purchase a total of 1,390,579 shares remain outstanding under the BYB Plan at September 30, 2020.

The types of stock options granted under the BYB Plan were Time Options and Performance Options. The exercise price of each option is equal to the fair value of the stock as of the date of grant. These option awards have vesting periods ranging from one to five years and have 10-year contractual terms. Stock volatility was computed as the average of the volatilities of peer group companies.

The vesting of Time Options is conditional based on completion of service. Performance Options have conditional vesting based on either performance targets or market performance. Certain Performance Options’ performance goals will be satisfied (in whole or in part) if the Bank achieves various performance targets such as profitability, asset quality, and conditional based on market performance, as outlined in the BYB Plan. Each of the performance goals identified are measured for achievement (or failure to achieve) independent of each other. In October 2017, the Board of Directors determined that the Performance Option goals were satisfied, in whole, and these Performance Options converted to Time Options. As a result of the previous completion of service, 414,894 performance options vested on October 3, 2017.

The fair values of the stock options were determined using the Black-Scholes-Merton model for Time Options and a Monte Carlo simulation model for Performance Options.

Pursuant to the terms of the Merger Agreement, upon the Effective Time, each outstanding First Evanston Option held by a participant in the First Evanston Bancorp, Inc. Stock Incentive Plan (the “FEB Plan”) ceased to represent a right to acquire shares of First Evanston common stock and was assumed and converted automatically into a fully vested and exercisable adjusted option to purchase shares of Byline common stock (each an “Adjusted Option”). In accordance with the Merger Agreement, the number of shares of Byline common stock to which each such Adjusted Option relates is equal to the product (rounded down to the nearest whole share of Byline common stock) of: (a) the number of shares of First Evanston common stock subject to the First Evanston Option immediately prior to May 31, 2018, multiplied by (ii) 4.725. Each Adjusted Option has an exercise price per share of Byline common stock equal to the quotient (rounded up to the nearest whole cent) of (x) the per share exercise price of such First Evanston Option immediately prior to May 31, 2018, divided by (y) 4.725.

The Company must receive approval of the Federal Reserve Board prior to any redemption of the Company Series B Preferred Stock.

For the three months ended September 30, 2020 and 2019, the Company declared and paid dividends on the Series B preferred stock of $196,000. For the nine months ended September 30, 2020 and 2019, the Company declared and paid dividends on the Series B preferred stock of $587,000.

On November 1, 2019, the Company announced that its Board of Directors approved a stock repurchase program authorizing the purchase of up to an aggregate of 1,250,000 shares of the Company’s outstanding common stock. The shares may, at the discretion of management, be repurchased from time to time in open market purchases as market conditions warrant or in privately negotiated transactions. The Company is not obligated to purchase any shares under the program, and the program may be discontinued at any time. The actual timing, number and share price of shares purchased under the repurchase program will be determined by the Company at its discretion and will depend on a number of factors, including the market price of the Company’s stock, general market and economic conditions and applicable legal requirements. The shares authorized to be repurchased represent approximately 3.3% of the Company’s outstanding common stock at June 30, 2020. The program will be in effect until December 31, 2020 unless terminated earlier. The program was paused in March 2020.

The Company repurchased 118,486 shares at a cost of $1.7 million under this program in the first quarter of 2020. Repurchased shares are recorded as treasury shares on the trade date using the treasury stock method, and the cash paid is recorded as treasury stock. Treasury stock acquired is recorded at cost and is carried as a reduction of stockholders’ equity in the Consolidated Statement of Financial Condition.

On September 8, 2020, the Company’s Board of Directors declared a cash dividend of $0.03 per share payable on October 6, 2020 to stockholders of record of the Company’s common stock as of September 22, 2020. No cash dividends were declared to common stockholders during the third quarter of 2019.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion and analysis of Byline Bancorp, Inc.’s financial condition and results of operations and should be read in conjunction with our Unaudited Interim Condensed Consolidated Financial Statements and notes thereto included elsewhere in this report. The words “the Company,” “we,” “Byline,” “our” and “us” refer to Byline Bancorp, Inc. and its consolidated subsidiaries, unless we indicate otherwise.

Overview

Our business

We are a bank holding company headquartered in Chicago, Illinois and conduct all our business activities through our subsidiary, Byline Bank, a full service commercial bank, and Byline Bank’s subsidiaries. Through Byline Bank, we offer a broad range of banking products and services to small and medium sized businesses, commercial real estate and financial sponsors and to consumers who generally live or work near our branches. In addition to our traditional commercial banking business, we provide small ticket equipment leasing solutions through Byline Financial Group, a wholly-owned subsidiary of Byline Bank, headquartered in Bannockburn, Illinois with sales offices in Illinois and New York, and sales representatives in Illinois, Michigan, New Jersey, and New York. We also participate in U.S. government guaranteed lending programs and originate U.S. government guaranteed loans. Byline Bank was the second most active originator of SBA loans in the country and the most active SBA lender in Illinois and Wisconsin, as reported by the SBA for the quarter ended September 30, 2020. Additionally, we provide trust and wealth management services to our customers. As of September 30, 2020, we had consolidated total assets of $6.5 billion, total gross loans and leases outstanding of $4.4 billion, total deposits of $4.8 billion, and total stockholders’ equity of $794.7 million.

Oak Park River Forest Acquisition

On April 30, 2019, we completed the acquisition of Oak Park River Forest Bankshares, Inc. (“Oak Park River Forest”), the parent company of Community Bank of Oak Park River Forest, under the terms of a definitive merger agreement. As a result of the merger, Oak Park River Forest’s wholly owned bank subsidiary, Community Bank of Oak Park River Forest, was merged with and into Byline Bank. As of the acquisition date, Oak Park River Forest had $329.8 million in assets, including $30.5 million of securities, $274.7 million of loans, and $290.2 million of deposits.

At the effective time of the merger, each share of Oak Park River Forest’s common stock was converted into the right to receive: (1) 7.9321 shares of Byline’s common stock, and (2) an amount in cash equal to $6.2 million divided by the number of outstanding shares of Oak Park River Forest common stock as of the closing date, with cash paid in lieu of fractional shares. Options to acquire Oak Park River Forest common stock that were outstanding at the Effective Time were paid in cash based on elections made by option holders, resulting in an aggregate stock options transaction value of $4.2 million. In the aggregate, Byline paid $6.2 million in cash and issued 1,464,558 shares of its common stock in respect of the outstanding shares of Oak Park River Forest common stock. The value of the total merger consideration at closing was approximately $35.5 million before issuance costs of $585,000.

Strategic Branch Consolidation

We continually perform strategic reviews of our existing banking footprint. With technology improvements and changes to customers’ banking preferences, we examine branch growth potential, customer usage, branch profitability, services provided, markets served and proximity to other locations with a goal of minimizing customer impact and deposit runoff. Since our recapitalization, which occurred in June 2013, our branch network has been reduced from 88 to 57, including eight branches added through the acquisition of First Evanston Bancorp, Inc. (“First Evanston”) and its subsidiary bank, First Bank & Trust in 2018 and three branches added through the Oak Park River Forest acquisition in 2019. During 2018 and 2019, we consolidated seven branches and two other facilities within our current network that had a minimal impact on our customer service levels, convenience, and business development capabilities. Additionally, during the first quarter of 2020, we consolidated another three branches and repurposed one with minimal customer impact, service levels, and overall convenience. These activities resulted in a one-time charge of approximately $437,000. We expect to generate $1.3 million in annual cost savings as a result of this consolidation, a portion of which we will seek to reinvest back into the business.

On September 18, 2020, we announced plans to optimize our branch network as part of efforts to accommodate changing customer behaviors while also recognizing operating efficiencies. We plan to consolidate 11 of our 57 full-service offices, or approximately 20% of our branch network. Most of the impacted branches are located within two miles of another Byline Bank branch that will continue to operate within the respective market. These branch consolidations are scheduled to

47

commence on December 31, 2020 and will result in a one-time charge of approximately $5.9 million, including $696,000 recognized during the third quarter 2020 related to salaries and employee benefit expenses. We anticipate annualized cost savings of approximately $4.3 million beginning in 2021, an estimated 25% of which will be utilized to increase investment in our digital banking platform and the continued renovation and upgrading of other retail branches.

We plan to continue to leverage our seasoned management team, the attractive market opportunity in the Chicago metropolitan area, our diversified lending approach and our track record of successfully integrating acquisitions to drive future growth. We believe that having a deep understanding of customers, longstanding ties to the communities in which we operate, a strong market position and exceptional employees allows us to provide the attention, responsiveness and customized service our clients seek while offering a diverse range of products to serve a variety of needs.

Response to COVID-19 Pandemic

The coronavirus disease 2019 (“COVID-19”) pandemic has caused health and economic concerns in the United States and globally. In March 2020, U.S. President Trump declared a public health and national emergency due to COVID-19, which resulted in mandatory stay-at-home orders in most U.S. states, including Illinois and Wisconsin. The impacts associated with the COVID-19 pandemic continue to have destabilizing and negative effects on global, national, and local economic and business activity. In response to this economic disruption, federal and state governments have recently enacted laws intending to stimulate the economy during this time. President Trump has signed into law three economic stimulus packages, including the $2.0 trillion Coronavirus Relief and Economic Security Act (the “CARES Act”) on March 27, 2020, which, among other things, initiated the Paycheck Protection Program (the “PPP”) under the Small Business Administration (“SBA”). PPP loans originated before June 5, 2020 have a two-year term and bear an interest rate of 1.0%, however borrowers can request an extension to five-years. PPP loans originated after June 5, 2020 have a five-year term and bear an interest rate of 1.0%. On April 16, 2020, the original $349.0 billion of funding for loans to small businesses under the PPP was depleted, and on April 27, 2020 the Federal government funded an additional $310.0 billion to the PPP. As a preferred SBA lender, we assisted our customers in participating in both the initial and second round of funding appropriations approved by Congress for the PPP, which was designed to help small businesses maintain their workforce during the COVID-19 pandemic. We were able to provide our customers with access to the PPP, and through September 30, 2020, we registered over 3,700 loans totaling $635.4 million. The Company received fee income from the Federal government of approximately $22.7 million. This fee income is deferred over the life of the PPP loan and before costs incurred by the Company, including technology costs for loan application and processing and loan servicing costs.

The CARES Act also temporarily eases the guidance applicable to loan modifications and the effect on assessing TDRs related to the COVID-19 pandemic. Modifications within the scope of this relief include arrangements that defer or delay payments of principal and/or interest and extend until the earlier of the following: 1) 60 days after the date on which the national emergency related to the COVID-19 outbreak is terminated; or 2) December 31, 2020. Through September 30, 2020, we approved approximately $631.8 million in COVID-19 related payment deferrals, or 16.8% of loans and leases, excluding PPP loans at September 30, 2020, primarily relating to our commercial banking customers. At September 30, 2020 we had $27.9 million in active COVID-19 related payment deferrals, or 0.74% of loans and leases, excluding PPP loans. We expect payment deferral requests from borrowers to continue throughout the COVID-19 pandemic, including our borrowers who have SBA 7(a) loans, and possibly beyond. We have also assisted our customers’ cash flow needs by waiving or refunding certain fees, including early withdrawal fees on time deposits.

As part of the CARES Act, the SBA is required to pay six months of principal, interest and any associated fees that borrowers owe for all current 7(a), 504, and Microloans in regular servicing status as well as new 7(a), 504, and Microloans disbursed prior to September 27, 2020. The payments to be made by the SBA are not deferments. These payments will be forgiven, and borrowers will not be expected to make these payments at a later date. At September 30, 2020, we have $87.1 million in SBA 7(a) loans that are receiving principal and interest payments under the CARES Act.

We have also initiated a series of measures to ensure the safety of employees, customers, and communities, to support customer needs, and to limit operational disruptions. We maximized social distancing protocols by augmenting business hours and the locations of employee teams. All of our non-retail employees have the ability to work from home and have done so during this time since mid-March 2020. We have temporarily closed 16 branches, converted 15 branches to drive-thru only locations, opened 15 hub branch locations allowing regular lobby traffic, and kept 11 full service branches

48

with lobby hours by appointment. We continue to proactively engage with our customers to assist them through these uncertain times.

Critical Accounting Policies and Significant Estimates

Our accounting and reporting policies conform to accounting principles generally accepted in the United States (“GAAP”) and to general practices within the Banking industry. To prepare financial statements and interim financial statements in conformity with GAAP, management makes estimates, assumptions and judgments based on available information. These estimates, assumptions and judgments affect the amounts reported in the financial statements and accompanying notes; and are based on information available as of the date of the financial statements. As this information changes, actual results could differ from the estimates, assumptions and judgments reflected in the financial statements. In particular, management has identified several accounting policies that, due to the estimates, assumptions and judgements inherent in those policies, are critical in understanding our financial statements.

These critical accounting policies and estimates include (i) acquisition‑related fair value computations, (ii) the carrying value of loans and leases, (iii) determining the provision and allowance for loan and lease losses, (iv) the valuation of intangible assets such as goodwill, servicing assets and core deposit intangibles, (v) the determination of fair value for financial instruments, including other-than-temporary-impairment losses, (vi) the valuation of real estate held for sale, and (vii) the valuation of or recognition of deferred tax assets and liabilities. An increase was made to the provision for loan and lease losses as a result of increases in qualitative factors relative to the COVID-19 pandemic.

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits us an extended transition period for complying with new or revised accounting standards affecting public companies. We have elected to take advantage of this extended transition period, which means that the financial statements included in this report, as well as any financial statements that we file in the future, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as we remain an emerging growth company or until we affirmatively and irrevocably opt out of the extended transition period provided for under the JOBS Act.

The following is a discussion of the critical accounting policies and significant estimates that require us to make complex and subjective judgments. Additional information about these policies can be found in Note 1 of our audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019, that we filed with the Securities and Exchange Commission (“SEC”) on March 12, 2020.

Business Combinations

We account for business combinations under the acquisition method of accounting in accordance with ASC 805. We recognize the fair value of the assets acquired and liabilities assumed as of the date of acquisition, with any excess of the fair value of consideration provided over the fair value of the identifiable net tangible and intangible assets acquired recorded as goodwill. Transaction costs are expensed as incurred. Application of the acquisition method requires extensive use of accounting estimates and judgements to determine the fair values of the identifiable assets acquired and liabilities assumed at the acquisition date.

In accordance with ASC 805, the acquiring company retains the right to make appropriate adjustments to the assets and liabilities of the acquired entity for information obtained during the measurement period about facts and circumstances that existed as of the acquisition date. The measurement period ends as of the earlier of (i) one year from the acquisition date or (ii) the date when the acquirer receives the information necessary to complete the business combination accounting.

Carrying Value of Loans and Leases

Our accounting methods for loans and leases differ depending on whether they are new or acquired loans and leases; and for acquired loans, whether the loans were acquired at a discount as a result of credit deterioration since the date of origination.

Originated Loans and Leases

We account for originated loans and leases and purchased loans and leases not acquired through business combinations as originated loans and leases. The new loans that management has the intent and ability to hold for the foreseeable future are reported at their outstanding principal balances net of any allowance for loan and lease losses, unamortized deferred fees and costs and unamortized premiums or discounts. The net amount of non-refundable loan

49

origination fees and certain direct costs associated with the lending process are deferred and amortized to interest income over the contractual lives of the new loans using methods which approximate the level yield method. Discounts and premiums are amortized or accreted to interest income over the estimated term of the new loans using methods that approximate the effective yield method. Interest income on new loans is accrued based on the unpaid principal balance outstanding. Additionally, once an acquired non-impaired loan reaches its contractual maturity date, it is re-underwritten, and if renewed, it is classified as an originated loan.

Acquired Loans and Leases

Acquired loans and leases are recorded at fair value as of the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either acquired impaired or acquired non‑impaired. Acquired impaired loans reflect evidence of credit deterioration since origination for which it is probable that all contractually required principal and interest will not be collected by us. Subsequent to acquisition, we periodically update for changes in cash flow expectations, which are reflected in interest income over the life of the loan as accretable yield. Any subsequent decreases in expected cash flow attributable to credit deterioration are recognized by recording a provision for loan losses.

For acquired non‑impaired loans and leases, the excess or deficit of the loan and lease principal balance over the fair value is recorded as a discount or premium at acquisition and is accreted through interest income over the life of the loan or lease. Subsequent to acquisition, these loans and leases are evaluated for credit deterioration and a provision for loan and lease losses would be recorded when probable loss is incurred. These loans and leases are evaluated for impairment consistent with originated loans and leases.

Provision and Allowance for Loan and Lease Losses

The provision for loan and lease losses reflects the amount required to maintain the allowance for loan and lease losses (“ALLL”) at an appropriate level based upon management’s evaluation of the adequacy of general and specific loss reserves.

The ALLL is maintained at a level that management believes is appropriate to provide for known and inherent incurred loan and lease losses as of the dates of the Consolidated Statements of Financial Condition, and we have established methodologies for the determination of its adequacy. The methodologies are set forth in a formal policy and take into consideration the need for an overall general valuation allowance as well as specific allowances that are determined on an individual loan basis. We increase our ALLL by charging provisions for probable losses against our income and decreased by charge‑offs, net of recoveries.

The evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses available information to recognize losses on loans and leases, changes in economic or other conditions may necessitate revision of the estimate in future periods.

The ALLL is maintained at a level management believes is sufficient to provide for probable losses based upon an ongoing review of the originated and acquired non‑impaired loan and lease portfolios by portfolio category, which include consideration of actual loss experience, peer loss experience, changes in the size and risk profile of the portfolio, identification of individual problem loan and lease situations which may affect a borrower’s ability to repay, and evaluation of prevailing economic conditions.

For acquired impaired loans, a specific valuation allowance is established when it is probable that we will be unable to collect all of the cash flows expected at acquisition, plus the additional cash flows expected to be collected arising from changes in estimates after acquisition.

The originated and non‑impaired acquired loans have limited delinquency and credit loss history and have not yet exhibited an observable loss trend. The credit quality of loans in these loan portfolios are impacted by delinquency status and debt service coverage generated by the borrowers’ businesses and fluctuations in the value of real estate collateral.

Acquired non‑impaired loans and originated loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. All acquired non‑impaired loans and originated loans of $100,000 or greater with an internal risk rating of substandard or below and on non-accrual, as well as loans classified as troubled debt restructurings (“TDR”), are reviewed individually for impairment on a quarterly basis.

50

In March 2020, CARES Act was signed into law. Section 4013 of the CARES Act temporarily eases the guidance applicable to loan modifications and the effect on assessing TDRs related to the COVID-19 pandemic. Modifications within the scope of this relief include arrangements that defer or delay payments of principal or interest and extend until th e earlier of the following: 1) s ixty days after the date on which the national emergency related to the COVID-19 outbreak is terminated; or 2) December 31, 2020.

Goodwill and Other Intangible Assets

Goodwill. Goodwill represents the excess of the purchase consideration over the fair value of net assets acquired in connection with our recapitalization and acquisitions using the acquisition method of accounting. Goodwill is not amortized but is periodically evaluated for impairment under the provisions of ASC Topic 350, Intangibles—Goodwill and Other (“ASC 350”).

Impairment testing is performed using either a qualitative or quantitative approach at the reporting unit level. Our goodwill is allocated to Byline Bank, which is our only applicable reporting unit for the purposes of testing goodwill for impairment. We have selected November 30 as the date to perform the annual goodwill impairment test. Additionally, we perform a goodwill impairment evaluation on an interim basis when events or circumstances indicate impairment potentially exists. Given recent events involving the declaration of federal and state emergencies as a result of the COVID-19 pandemic, we qualitatively evaluated goodwill and determined goodwill was not impaired as of September 30, 2020.

The ongoing impact of the COVID-19 pandemic may cause an additional and sustained decline in our common stock price, which may require added qualitative and quantitative analysis and may result in an impairment charge being recorded in a future period. If we should conclude that all or a portion of our goodwill is impaired, we would record a non-cash charge to earnings for the amount of such impairment. Such a charge would have no impact on tangible capital or regulatory capital. At September 30, 2020, we had goodwill of $148.4 million, or approximately 18.7% of equity.

Servicing Assets. Servicing assets are recognized separately when they are acquired through sales of loans or when the rights to service loans are purchased. When loans are sold with servicing rights retained, servicing assets are recorded at fair value in accordance with ASC Topic 860, Transfers and Servicing (“ASC 860”). Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in the prepayment speed and discount rate assumptions have the most significant impact on the fair value of servicing rights. See Note 7 and Note 15 of our Unaudited Interim Condensed Consolidated Financial Statements as of September 30, 2020, included in this report, for additional information.

Core Deposit Intangible Assets. Other intangible assets primarily consist of core deposit intangible assets. In valuing core deposit intangibles, we consider variables such as deposit servicing costs, attrition rates and market discount rates. Core deposit intangibles are reviewed annually, or more frequently when events or changes in circumstances occur that indicate that their carrying values may not be recoverable. If the recoverable amount of the core deposit intangibles is determined to be less than its carrying value, we would then measure the amount of impairment based on an estimate of the fair value at that time. We also evaluate whether the events or circumstances have occurred that warrant a revision to the remaining useful lives of intangible assets. In cases where a revision is deemed appropriate, the remaining carrying amounts of the intangible assets are amortized over the revised remaining useful life. Core deposit intangibles are currently amortized over an approximate ten year period.

Customer Relationship Intangible. Other intangible assets also include our customer relationship intangible asset. In valuing our customer relationship intangibles, we consider variables such as assets under management, attrition rates, and fee structure. Customer relationship intangibles are currently amortized over a 12 year period.

Fair value of Financial Instruments

ASC Topic 820, Fair Value Measurement defines fair value as the price that would be received to sell a financial asset or paid to transfer a financial liability in an orderly transaction between market participants at the measurement date.

The degree of management judgment involved in determining the fair value of assets and liabilities is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not available, management judgment is necessary to estimate fair value. In addition, changes in market conditions may reduce the availability of quoted prices or observable data. For example, reduced liquidity in the capital markets or changes in secondary market activities could result in observable market inputs

51

becoming unavailable. Therefore, when market data is not available, we would use valuation techniques requiring more management judgment to estimate the appropriate fair value measurement.

See Note 15 of our Unaudited Interim Condensed Consolidated Financial Statements as of September 30, 2020, included in this report, for a complete discussion of our use of fair value of financial assets and liabilities and their related measurement practices.

Valuation of Real Estate Held for Sale

Other Real Estate Owned (“OREO”). OREO includes real estate assets that have been acquired through, or in lieu of, loan foreclosure or repossession and are to be sold. OREO assets are initially recorded at fair value, less estimated costs to sell, of the collateral of the loan, on the date of foreclosure or repossession, establishing a new cost basis. Adjustments that reduce loan balances to fair value at the time of foreclosure or repossession are recognized as charge‑offs in the allowance for loan and lease losses. Positive adjustments, if any, at the time of foreclosure or repossession are recognized in non‑interest expense. After foreclosure or repossession, management periodically obtains new valuations and real estate or other assets may be adjusted to a lower carrying amount, determined by the fair value of the asset, less estimated costs to sell. Any subsequent write‑downs are recorded as a decrease in the asset and charged against other real estate owned valuation adjustments, included within non-interest expense. Operating expenses of such properties, net of related income, are included in non‑interest expense, and gains and losses on their disposition are included in non‑interest expense. Gains on internally financed other real estate owned sales are accounted for in accordance with the methods stated in ASC Topic 360‑20, Real Estate Sales (“ASC 360‑20”). Any losses on the sales of other real estate owned properties are recognized immediately.

Assets Held for Sale. Assets held for sale consist of former branch locations and real estate purchased for expansion. Assets are considered held for sale when management has approved a plan to sell the assets following a branch closure or other events. The properties are being actively marketed and transferred to assets held for sale based at the lower of its carrying value or its fair value, less estimated costs to sell. Adjustments to reduce the asset balances to fair value are recorded at the time of transfer and are recognized through a charge against income. An assessment of the recoverability of other long-lived assets associated with all branches is periodically performed, resulting in impairment losses which are reflected in other non-interest expense.

Income Taxes

We use the asset and liability method to account for income taxes. The objective of the asset and liability method is to establish deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the income tax basis of our assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. Our annual tax rate is based on our income, statutory tax rates and available tax planning opportunities. Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in determining tax expense and in evaluating tax positions, including evaluating uncertainties.

52

Deferred income tax assets represent amounts available to reduce income taxes payable on taxable income in future years. Such assets arise because of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as from net operating loss carryforwards. We review our deferred tax positions quarterly for changes which may impact realizability. We evaluate the recoverability of these future tax deductions by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies. We use short and long‑range business forecasts to provide additional information for its evaluation of the recoverability of deferred tax assets. It is our policy to recognize interest and penalties associated with uncertain tax positions, if applicable, as components of non‑interest expense.

A deferred tax valuation allowance is established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some of the deferred tax asset will not be realized. See Note 11 of the notes to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019, for further information on income taxes.

Refer to Note 2 of our Unaudited Interim Condensed Consolidated Financial Statements as of September 30, 2020, included in this report, for a description of recent accounting pronouncements, including the effective dates of adoption and anticipated effects on our results of operations and financial condition.

Primary Factors Used to Evaluate Our Business

As a financial institution, we manage and evaluate various aspects of both our results of operations and our financial condition. We evaluate the levels and trends of the line items included in our consolidated balance sheet and income statement as well as various financial ratios that are commonly used in our industry. We analyze these ratios and financial trends against our own historical performance, our budgeted performance and the final condition and performance of comparable financial institutions in our region. Comparison of our financial performance against other financial institutions is impacted by the accounting for acquired non‑impaired and acquired impaired loans.

These factors and metrics described in this report may not provide an appropriate basis to compare our results or financial condition to the results or financial condition of other financial services companies, given our limited operating history and strategic acquisitions since our recapitalization.

Results of Operations

Overview

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of interest income on loans and lease receivables, including accretion income on loans, investment securities and other short-term investments, and interest expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent upon our generation of non-interest income, consisting primarily of income from fees and service charges on deposits, loan servicing revenue, wealth management and trust income, ATM and interchange fees, and net gains on sales of investment securities and loans. Other factors contributing to our results of operations include our provisions for loan and lease losses, provision for income taxes, and non-interest expenses, such as salaries and employee benefits, occupancy and equipment expenses, and other miscellaneous operating costs.

Our results for the first nine months of 2020 were impacted by additional provision for loan and lease losses, leading to an increase in the allowance for loan and lease losses to reflect the weakening economic conditions and uncertainty due to the COVID-19 pandemic.

We reported consolidated net income of $13.1 million for the three months ended September 30, 2020 compared to net income of $15.3 million for the three months ended September 30, 2019, a decrease of $2.3 million or 14.8%. The decrease in net income was primarily attributable to a $9.8 million increase in provision for loan and lease losses, and a $4.3 million decrease in net interest income, offset by a $7.4 million increase in non-interest income, a $3.7 million decrease in non-interest expense, and a $663,000 decrease in provision for income taxes.

The decrease in net interest income during the three months ended September 30, 2020 was mainly a result of decreased average yields on securities and loans and leases, partly offset by decreased cost of funds. The increase in provision for loan and lease losses reflects specific impairment provided for non-performing loans as well as qualitative allocations to address the impact of the COVID-19 pandemic. The increase in non-interest income was principally driven by an increase in loan servicing asset valuation and net gains on sale of loans. The decrease in non-interest expense was mostly due to a decrease in salaries and employee benefits, a decrease in legal, audit, and other professional fees and data processing expenses. The decrease in provision for income taxes was driven by a decrease in net income before provision for income taxes during the period.

Net income available to common stockholders was $12.9 million, or $0.34 per basic and diluted common share, for the three months ended September 30, 2020 compared to $15.1 million, or $0.40 per basic and $0.39 per diluted common share, for the three months ended September 30, 2019. Dividends on preferred shares were $196,000 for the three months ended September 30, 2020 and 2019.

Our annualized return on average assets was 0.81% for the three months ended September 30, 2020 compared to 1.12% for the three months ended September 30, 2019. Our annualized return on average stockholders’ equity was 6.57% for the three months ended September 30, 2020 compared to 8.34% for the three months ended September 30, 2019. Our efficiency ratio was 52.47% for the three months ended September 30, 2020 compared to 59.81% for the three months ended September 30, 2019.

We reported consolidated net income of $25.2 million for the nine months ended September 30, 2020 compared to net income of $41.2 million for the nine months ended September 30, 2019, a decrease of $16.0 million, or 38.8%. The decrease in net income was primarily attributable to a $29.4 million increase in provision for loan and lease losses and a $3.4 million decrease in net interest income, offset by a $3.2 million increase in non-interest income, a $7.8 million decrease in non-interest expense, and a $5.8 million decrease in provision for income taxes.

The decrease in net interest income was mostly due to a decrease in interest and fees on loans and leases, which was partially offset by a decrease in interest expense, primarily attributable to interest expense on deposits. The increase in provision for loan and lease losses reflects specific impairment provided for non-performing loans as well as qualitative allocations to address the impact of the COVID-19 pandemic. The increase in non-interest income was driven by an increase in loan servicing asset revaluation, net gains on sales of securities available-for sale, and loan servicing revenue. The decrease in non-interest expense was a result of a decrease in salaries and employee benefits as a result of an increase in deferred costs for the origination of PPP loans, a decrease in data processing expense, and a decrease in legal, audit and other professional fees. The decrease in provision for income taxes was due to a decrease in net income before provision for income taxes during the period.

Net income available to common stockholders was $24.6 million, or $0.65 per basic and $0.64 per diluted common share, for the nine months ended September 30, 2020 compared to $40.6 million, or $1.09 per basic and $1.07 per diluted common share, for the nine months ended September 30, 2019. Dividends on preferred shares were $587,000 for the nine months ended September 30, 2020 and 2019.

Our annualized return on average assets was 0.56% for the nine months ended September 30, 2020 compared to 1.05% for the nine months ended September 30, 2019. Our annualized return on average stockholders’ equity was 4.33% for the nine months ended September 30, 2020 compared to 7.91% for the nine months ended September 30, 2019. Our efficiency ratio was 57.35% for the nine months ended September 30, 2020 compared to 61.15% for the nine months ended September 30, 2019.

Net Interest Income

Net interest income, representing interest income less interest expense, is a significant contributor to our revenues and earnings. We generate interest income from interest and dividends on interest-earning assets, which include loans, leases and investment securities we own. We incur interest expense from interest paid on interest-bearing liabilities, which include interest-bearing deposits, subordinated debt, FHLB advances, junior subordinated debentures and other borrowings. To evaluate net interest income, we measure and monitor (i) yields on our loans and other interest-earning assets, (ii) the costs of our deposits and other funding sources, (iii) our net interest spread, and (iv) our net interest margin. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as the annualized net interest income divided by average interest-earning assets. Because non-interest-bearing sources of funds, such as non-interest-bearing deposits and stockholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these non-interest-bearing sources.

We also recognize income from the accretable discounts associated with the purchase of interest-earning assets. Because of our recapitalization and bank acquisitions, we derive a portion of our interest income from the accretable discounts on acquired loans. The accretion is generally recognized over the life of the loan and is impacted by changes in expected cash flows on the loan. This accretion will continue to have an impact on our net interest income as long as loans acquired with a discount at acquisition represent a meaningful portion of our interest-earning assets. As of September 30, 2020, acquired loans with evidence of credit deterioration accounted for under ASC Topic 310-30, Accounting for Purchased Loans with Deteriorated Credit Quality, represented 5.0% of our total loan portfolio compared to 6.8% at December 31, 2019.

Changes in the market interest rates we earn on interest-earning assets or pay on interest-bearing liabilities, as well as the volume and types of interest-earning assets, interest-bearing and non-interest-bearing liabilities, are usually the largest drivers of periodic changes in net interest spread, net interest margin and net interest income. In addition, our interest income includes the accretion of the discounts on our acquired loans, which will also affect our net interest spread, net interest margin and net interest income.

Increases and decreases in interest income and interest expense result from changes in average balances (volume) of interest-earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following table sets forth the effects of changing rates and volumes on our net interest income during the periods shown. Information is provided with respect to (i) effects on interest income attributable to changes in volume (changes in volume multiplied by prior rate) and (ii) effects on interest income attributable to changes in rate (changes in rate multiplied by prior volume). Changes applicable to both volume and rate have been allocated to volume. Yields have been calculated on a pre-tax basis. The table below is a summary of increases and decreases in interest income and interest expense resulting from changes in average balances (volume) and changes in average interest rates (dollars in thousands):

Net interest income for the three months ended September 30, 2020 was $53.5 million compared to $57.8 million during the same period in 2019, a decrease of $4.3 million, or 7.5%. Interest income decreased $12.8 million for the three months ended September 30, 2020 compared to the same period in 2019 primarily a result of decreased average yields on loans and leases as market interest rates decreased from a year ago partly offset by loan and lease growth through originations. Interest expense decreased by $8.5 million for the three months ended September 30, 2020 compared to the same period in 2019 mostly due to decreases in the average rates paid on deposits and other borrowings as well as a change in deposit mix.

Net interest income for the nine months ended September 30, 2020 was $159.0 million compared to $162.4 million during the same period in 2019, a decrease of $3.4 million, or 2.1%. Interest income decreased $19.6 million for the nine months ended September 30, 2020 compared to the same period in 2019 primarily a result of decreased average yields on loans and leases as market interest rates decreased from a year ago as well as lower-yielding PPP loan balances partly offset by loan and lease growth through origination and purchases of mortgage-backed securities. Interest expense decreased by $16.2 million for the nine months ended September 30, 2020 compared to the same period in 2019 mostly due to decreases in the average rates paid on deposits and borrowings as well as a change in deposit mix.

The net interest margin for the three months ended September 30, 2020 was 3.60%, a decrease of 102 basis points compared to 4.62% for the three months ended September 30, 2019. The net interest margin for the nine months ended September 30, 2020 was 3.81%, a decrease of 71 basis points compared to 4.52% for the nine months ended September 30, 2019. The primary driver of the decrease for the three and nine month periods was a decrease in average loan and lease yields resulting from decreased market interest rates, lower-yielding PPP loan balances, and decreased loan accretion. Those decreases were partly offset by a lower cost of funds resulting from decreased market interest rates and the access of funds available to borrow at a lower cost as well as higher non-interest-bearing demand deposit balances.

Net loan accr etion income was $3.9 million for the three months ended September 30, 2020 compared to $7.7 million for the three months ended September 30, 2019, a decrease of $3.8 million, or 49.2%. Net loan accr etion income was $10.8 million for the nine months ended September 30, 2020 compared to $17.8 million for the nine months ended September 30, 2019, a decrease of $7.0 million, or 39.5%. Total net loan accretion on acquired loans contributed 26 basis points to the net interest margin for the three months ended September 30, 2020 compared to 62 basis points for the three months ended September 30, 2019. Total net loan accretion on acquired loans contributed 26 basis points to the net interest margin for the nine months ended September 30, 2020 compared to 50 basis points for the nine months ended September 30, 2019. Projected accretion income as of September 30, 2020 is summarized as follows:

Provision for Loan and Lease Losses

The provision for loan and lease losses represents a charge to earnings necessary to establish an allowance for loan and lease losses that, in management’s evaluation, is appropriate to provide coverage for probable losses incurred in the loan and lease portfolio. The allowance for loan and lease losses is increased by the provision for loan and lease losses and is decreased by charge-offs, net of recoveries on prior charge-offs.

Provisions for loan and lease losses were $15.7 million and $5.9 million for the three months ended September 30, 2020 and 2019, respectively, an increase of $9.8 million, or 165.4%. Provisions for loan and lease losses were $45.7 million and $16.3 million for the nine months ended September 30, 2020 and 2019, respectively, an increase of $29.4 million, or 180.1%. The increase reflects specific impairment provided for non-performing loans, including the unguaranteed portion of U.S. government guaranteed loans and increases to our general reserves, including allocations of $8.4 million and $22.0 million, for the three and nine months ended September 30, 2020, respectively, to address the uncertainty and impact of the COVID-19 pandemic. The ALLL as a percentage of loans and leases increased from 0.84% at December 31, 2019 to 1.40% at September 30, 2020. The ALLL as a percentage of loans and leases excluding PPP loans was 1.63% at September 30, 2020.

Non-Interest Income

Non-interest income was $22.3 million for the three months ended September 30, 2020 compared to $14.8 million for the three months ended September 30, 2019, an increase of $7.4 million, or 50.3%. The increase was primarily due to an increase in net gains on sale of loans and an increase in loan servicing asset revaluation.

Non-interest income was $44.2 million for the nine months ended September 30, 2020 compared to $41.0 million for the nine months ended September 30, 2019, an increase of $3.2 million, or 7.9%. The increase was primarily due to an increase in loan servicing asset revaluation and an increase in net gains on securities available-for-sale.

While portions of the loans that we originate are sold and generate gain s on sale revenue, servicing rights for the majority of loans that we sell are retained by us. In exchange for continuing to service loans that have been sold, we receive servicing revenue from a portion of the interest cash flow of the loan. We generated $2.9 million in loan servicing revenue on the sold portion of the U.S. government guaranteed loans for the three months ended September 30, 2020 compared to $2.7 million for the three months ended September 30, 2019, an increase of $244,000 or 9.1%. We generated $8.7 million in loan servicing revenue on the sold portion of the U.S. government guaranteed loans for the nine months ended September 30, 2020 compared to $7.9 million for the nine months ended September 30, 2019, an increase of $813,000 or 10.4%. The increase was mainly driven by an increase in total loans serviced due to additional U.S government guaranteed loans sold with retained servicing rights during the periods. At September 30, 2020 and 2019, the outstanding balance o f guaranteed loans serviced was $1.5 billion and $1.3 billion, respectively.

Loan servicing asset revaluation represents net changes in the fair value of our servicing assets. Loan servicing asset revaluation had a upward adjustment of $1.1 million for the three months ended September 30, 2020 compared to a downward adjustment of $1.6 million for the three months ended September 30, 2019, an increase of $2.7 million, or 169.8%, due to a decrease in discount rate as a result of improving secondary market pricing during third quarter of 2020 and slower prepayment speeds. Loan servicing asset revaluation had a downward adjustment of $2.7 million for the nine months ended September 30, 2020 compared to $4.1 million for the nine months ended September 30, 2019, a decrease of $1.4 million, or 35.2%, due to secondary market volatility late in the first quarter of 2020 and early in the second quarter 2020 as a result of the COVID-19 pandemic.

ATM and interchange fees were $1.0 million for the three months ended September 30, 2020 compared to $973,000 for the three months ended September 30, 2019, an increase of $55,000, or 5.7%. The increase was mostly due to higher third-party merchant fees. ATM and interchange fees were $3.1 million for the nine months ended September 30, 2020 compared to $2.6 million for the nine months ended September 30, 2019, an increase of $454,000, or 17.2%. The increase was mainly driven by higher interchange income as a result of a signing bonus for a new payment processing merchant.

Net gains on sales of securities were $1.0 million during the three months ended September 30, 2020 compared to $178,000 for the three months ended September 30, 2019. Net gains on sales of securities were $2.4 million during the nine months ended September 30, 2020 compared to $1.2 million for the nine months ended September 30, 2019, an increase of $1.3 million, or 109.6%. We sold $80.5 million of securities during the nine months ended September 30, 2020 and $92.1 million during the nine months ended September 30, 2019.

Change in fair value of equity securities, net, was a $154,000 increase and a $15,000 decrease in fair value for the three months ended September 30, 2020 and 2019, respectively. Change in fair value of equity securities, net, was a $301,000 and $1.0 million increase in fair value for the nine months ended September 30, 2020 and 2019, respectively. The amount recorded during the periods were a result of the increase or decrease in the fair value of these securities.

Net gains on sales of loans were $12.7 million for the three months ended September 30, 2020 compared to $9.4 million for the three months ended September 30, 2019, an increase of $3.3 million, or 34.7%. We sold $121.2 million of U.S. government guaranteed loans during the three months ended September 30, 2020 compared to $93.3 million during the three months ended September 30, 2019. Net gains on sales of loans were $23.9 million for the nine months ended September 30, 2020 compared to $23.1 million for the nine months ended September 30, 2019, an increase of $790,000, or 3.4%. We sold $260.9 million of U.S. government guaranteed loans during the nine months ended September 30, 2020 compared to $234.7 million during the nine months ended September 30, 2019. The increase in net gains on sales was mainly driven by increased demand for U.S. government guaranteed loans.

Wealth management and trust income represents fees charged to customers for investment, trust, or wealth management services and are primarily determined by total assets under management. Wealth management and trust income was $693,000 for the three months ended September 30, 2020 compared to $653,000 for the three months ended September 30, 2019. Wealth management and trust income was $2.0 million for the nine months ended September 30, 2020 compared to $1.9 million for the nine months ended September 30, 2019. Assets under management were $557.9 million and $566.0 million as of September 30, 2020 and 2019, respectively. The variances were mostly driven by market conditions.

Other non-interest income was $1.0 million for the three months ended September 30, 2020 compared to $918,000 for the three months ended September 30, 2019, an increase of $90,000 or 9.7%. Other non-interest income was $1.8 million for the nine months ended September 30, 2020 compared to $2.6 million for the nine months ended September 30, 2019, a decrease of $793,000 or 30.7%. The primary driver of the de crease in the period was decreased swap and other operating income.

Non-Interest Expense

Non-interest expense was $41.7 million for the three months ended September 30, 2020 compared to $45.4 million for the three months ended September 30, 2019, a decrease of $3.7 million, or 8.2%. The decrease was primarily due to a decrease in decrease in legal, audit, and other professional fees and data processing expenses. Non-interest expense was $122.2 million for the nine months ended September 30, 2020 compared to $130.1 million for the nine months ended September 30, 2019, a decrease of $7.8 million, or 6.0%. The decrease was primarily due to a decrease in salaries and employee benefits as a result of an increase in deferred costs for the origination of PPP loans and a decrease data processing expenses.

The following table presents the major components of our non-interest expense for the periods indicated (dollars in thousands):

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |
|  | 2020 |  |  | 2019 |  |  | 2020 |  |  | 2019 |

Salaries and employee benefits, the single largest component of our non-interest expense, totaled $23.1 million for the three months ended September 30, 2020 compared to $24.5 million for the three months ended September 30, 2019, a decrease of $1.4 million, or 5.8%. Salaries and employee benefits totaled $67.2 million for the nine months ended September 30, 2020 compared to $71.1 million for the nine months ended September 30, 2019, a decrease of $3.9 million, or 5.5%. The decrease resulted from an increase in deferred costs for the origination of PPP loans partly offset by organizational growth and increased employer costs related to benefits.

Occupancy and equipment expense was $5.2 million for the three months ended September 30, 2020 compared to $4.5 million for the three months ended September 30, 2019, an increase of $708,000, or 15.1%.

The increase in the periods was a result of our additional branches resulting from the bank acquisition in the second quarter of 2019. The increase was also a result of increased real estate taxes and increased investment in equipment and technology assets.

Loan and lease related expenses were $2.1 million for the three months ended September 30, 2020 compared to $1.9 million for the three months ended September 30, 2019, an increase of $104,000, or 5.3%. Loan and lease related expenses were $4.6 million for the nine months ended September 30, 2020 compared to $5.4 million for the nine months ended September 30, 2019, a decrease of $743,000, or 13.8%. The decrease was principally driven by higher loan expense reimbursements from borrowers in the periods.

Legal, audit, and other professional fees were $2.4 million for the three months ended September 30, 2020 compared to $4.1 million for the three months ended September 30, 2019, a decrease of $1.7 million, or 41.2%. Legal, audit, and other professional fees were $6.8 million for the nine months ended September 30, 2020 compared to $9.1 million for the nine

months ended September 30, 2019, a decrease of $2.3 million, or 25.4%. The decrease reflects the merger expenses and other strategic projects in the third quarter of 2019.

Data processing expense was $2.7 million for the three months ended September 30, 2020 compared to $4.1 million for the three months ended September 30, 2019, a decrease of $1.4 million, or 34.5%. The decrease was primarily due to expenses in connection with the Oak Park River Forest core system conversion during the third quarter of 2019. Data processing expense was $8.2 million for the nine months ended September 30, 2020 compared to $11.1 million for the nine months ended September 30, 2019, a decrease of $2.9 million, or 26.3%. The decrease reflects the merger expenses related to the Oak Park River Forest acquisition and the core system integration expenses in the second quarter of 2019.

Net loss recognized on other real estate owned and other related expenses was $349,000 for the three months ended September 30, 2020 compared to $94,000 for the three months ended September 30, 2019, an increase of $255,000, or 271.3%. Net loss recognized on other real estate owned and other related expenses was $1.3 million for the nine months ended September 30, 2020 compared to $543,000 for the nine months ended September 30, 2019, an increase in expense of $781,000, or 117.6%. These increases were primarily due to impairments of other real estate owned.

Other intangible assets amortization expense was $1.9 million for the three months ended September 30, 2020 compared to $2.0 million for the three months ended September 30, 2019, a decrease of $56,000, or 2.8%. Other intangible assets amortization expense was $5.7 million for the nine months ended September 30, 2020 compared to $5.7 million for the nine months ended September 30, 2019, a decrease of $3,000, or 0.1%.

Other non-interest expense was $4.0 million for the three months ended September 30, 2020 compared to $4.2 million for the three months ended September 30, 2019, a decrease of $263,000 or 6.2%. The decrease was mostly due to lower advertising expense and other operating expenses. Other non-interest expense was $12.3 million for the nine months ended September 30, 2020 and $12.7 million for the nine months ended September 30, 2019, a decrease of $347,000, or 2.7%. This decrease is principally attributed to a decrease in advertising expense offset by an increase in FDIC insurance assessment.

Our efficiency ratio was 52.47% for the three months ended September 30, 2020 compared to 59.81% for the three months ended September 30, 2019. The improvement in our efficiency ratio for the three months ended September 30, 2020 was driven by both a decrease in our non-interest expense and an increase in our non-interest income. Our adjusted efficiency ratio was 52.43% for the three months ended September 30, 2020 compared to 58.17% for the three months ended September 30, 2019. Our efficiency ratio was 57.35% for the nine months ended September 30, 2020 compared to 61.15% for the nine months ended September 30, 2019. The improvement in our efficiency ratio for the nine months ended September 30, 2020 was driven by decreased non-interest expense. Our adjusted efficiency ratio was 56.98% for the nine months ended September 30, 2020 compared to 57.87% for the nine months ended September 30, 2019. Please refer to the “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of our non-GAAP measures to the most directly comparable GAAP financial measure.

Income Taxes

Our provision for income taxes for the three months ended September 30, 2020 totaled $5.3 million compared to $5.9 million for the three months ended September 30, 2019. The decrease in income tax expense was principally due to decreased income before provision for income taxes during the period. Our effective tax rate was 28.7% for the three months ended September 30, 2020 and 27.9% for the three months ended September 30, 2019.

Our provision for income taxes for the nine months ended September 30, 2020 totaled $10.0 million compared to $15.8 million for the nine months ended September 30, 2019. The decrease in income tax expense was principally due to decreased income before provision for income taxes during the period. Our effective tax rate was 28.5% for the nine months ended September 30, 2020 and 27.7% for the nine months ended September 30, 2019.

Financial Condition

Balance Sheet Analysis

Our total assets increased by $974.7 million, or 17.7%, to $6.5 billion at September 30, 2020 compared to $5.5 billion at December 31, 2019. The increase in total assets includes an increase of $588.9 million, or 15.6%, in loans and leases from $3.8 billion at December 31, 2019 to $4.4 billion at September 30, 2020. Our originated loan and lease portfolio increased by $800.9 million and our acquired loan and lease portfolio decreased by $212.1 million. The increase in our originated portfolio was primarily attributed to organic loan and lease growth, mostly PPP loans, and renewals of acquired non-impaired loans that are now reflected with originated loans. The decrease in our acquired portfolio was attributed to renewals reflected in originated loans, payoffs, and pay downs during the period.

Total liabilities increased by $930.1 million, or 19.5%, to $5.7 billion at September 30, 2020 compared to $4.8 billion at December 31, 2019. Total deposits increased by $662.7 million, or 16.0%, driven by growth in non-interest-bearing deposits, money market demand deposits, and interest-bearing checking accounts, partly offset by a decrease in time deposits. Borrowings increased by $243.2 million, or 42.4%.

Investment Portfolio

Our investment securities portfolio consists of securities classified as available-for-sale and held-to-maturity. There were no securities classified as trading in our investment portfolio as of September 30, 2020 or December 31, 2019. All available-for sale securities are carried at fair value and may be used for liquidity purposes should management consider it to be in our best interest. Securities available-for-sale consist primarily of residential mortgage-backed securities, commercial mortgage- backed securities and U.S. government agencies securities.

Securities available-for-sale increased $322.9 million, or 27.2%, from $1.2 billion at December 31, 2019 to $1.5 billion at September 30, 2020. The increase was mainly attributed to purchases of mortgage-backed securities.

At September 30, 2020, our held-to-maturity securities portfolio consists of obligations of states, municipalities and political subdivisions. We carry these securities at amortized cost. Securities held-to-maturity were $4.4 million at September 30, 2020 and December 31, 2019.

We had no securities that were classified as having other-than-temporary-impairment (“OTTI”) as of September 30, 2020 or December 31, 2019.

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. At September 30, 2020, we evaluated the securities which had an unrealized loss for OTTI and determined all declines in value to be temporary. There were 41 investment securities with unrealized losses at September 30, 2020. We anticipate full recovery of amortized cost with respect to these securities by maturity, or sooner in the event of a more favorable market interest rate environment. We do not intend to sell these securities and it is not more likely than not that we will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

Restricted Stock

As a member of the Federal Home Loan Bank system, Byline Bank is required to maintain an investment in the capital stock of the FHLB. No market exists for this stock, and it has no quoted market value. The stock is redeemable at par by the FHLB and is, therefore, carried at cost. In addition, Byline Bank owns stock of Bankers’ Bank that was acquired as part of a bank acquisition. The stock is redeemable at par and carried at cost. As of September 30, 2020 and December 31, 2019, we held $9.7 million and $22.1 million, respectively, in FHLB and Bankers’ Bank stock. We evaluate impairment of our investment in FHLB and Bankers’ Bank based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. We did not identify any indicators of impairment of FHLB and Bankers’ Bank stock as of September 30, 2020 and December 31, 2019.

Loan and Lease Portfolio

Lending-related income is the most important component of our net interest income and is the main driver of the results of our operations. Total loans and leases at September 30, 2020 and December 31, 2019 were $4.4 billion and $3.8 billion, respectively, an increase of $588.9 million, or 15.6%. Originated loans were $3.6 billion at September 30, 2020, an

increase of $800.9 million, or 28.2%, compared to $2.8 billion at December 31, 2019. Acquired impaired loans and acquired non-impaired loans and leases were $737.9 m illion at September 30, 2020, a decrease of $212.1 million, or 22.3%, compared to $950.0 m illion at December 31, 2019. The increase in our originated portfolio wa s primarily attributed to organic loan and lease growth, primarily PPP loans, and renewals of acquired non-impaired loans that are now reflected with originated loans. The decrease in our acquired portfolio is attributed to renewals reflected in originated loans, payoffs, and pay downs during the period.

We strive to maintain a relatively diversified loan portfolio to help reduce the risk inherent in concentration in certain types of collateral. Loans, excluding leases, are typically made to real estate, manufacturing, wholesale, retail and service businesses for working capital needs, business expansions and operations. The Company's exposure to certain industries as of September 30, 2020 represents the following percentages of the portfolio: 27.4% real estate, 15.1% manufacturing, 7.9% consumer, 6.5% wholesale trade, 5.9% accommodation and food service, 6.5% retail trade, and all other industries individually represent less than 5% of the portfolio or 9.5% of the total loan portfolio. As of September 30, 2020, the loan portfolio included $396.0 million of unguaranteed 7(a) SBA and USDA loans with exposure to the following top three industries: 18.3% food services, 15.4% retail trade, and 13.0% manufacturing.

The expected life of our loan portfolio will differ from contractual maturities because borrowers may have the right to curtail or prepay their loans with or without penalties. Because a portion of the portfolio is accounted for under ASC 310-30, the carrying value is significantly affected by estimates and it is impracticable to allocate scheduled payments for those loans based on those estimates. Consequently, the tables presented include information limited to contractual maturities of the underlying loans.

Allowance for Loan and Lease Losses

The ALLL is determined by us on a quarterly basis, although we are engaged in monitoring the appropriate level of the allowance on a more frequent basis. The ALLL reflects management’s estimate of probable incurred credit losses inherent in the loan and lease portfolios. The computation includes elements of judgement and high levels of subjectivity.

Factors considered by us include, but are not limited to, actual loss experience, peer loss experience, changes in size and risk profile of the portfolio, identification of individual problem loan and lease situations which may affect a borrower’s ability to repay, and evaluation of the prevailing economic conditions. Changes in conditions may necessitate revision of the estimate in future periods.

We assess the ALLL based on three categories: (i) originated loans and leases, (ii) acquired non-impaired loans and leases, and (iii) acquired impaired loans with further credit deterioration after the acquisitions or our recapitalization.

Total ALLL was $61.3 million at September 30, 2020 compared to $31.9 million at December 31, 2019, an increase of $29.3 million, or 91.8%. The increase was primarily due to increases in the general reserve driven by newly originated loans and leases and renewals of acquired non-impaired loans that are also reflected within originated loans and leases, and specific impairments in the unguaranteed portion of the U.S. government guaranteed portfolio as well as commercial loan relationships. The increase also includes allocations of $22.0 million to address the estimated impact of the uncertainty caused by the COVID-19 pandemic. Economic factors considered in recognizing the additional allocation includes the impact that an increased unemployment rate due to sheltering in place had on a borrowers’ ability to repay loans; and an increase in watch and classified loans.

Total ALLL to total loans and leases held for investment, net before ALLL, was 1.40% and 0.84% of total loans and leases at September 30, 2020 and December 31, 2019, respectively. The increase was primarily driven by an increase in specific impairments on non-performing loans, including the unguaranteed portion of U.S. government guaranteed loans, and increases to our general reserve to address the impact of the COVID-19 pandemic and the continued economic uncertainty.

Non-Performing Assets

Non-performing loans and leases include loans and leases 90 days past due and still accruing and loans and leases accounted for on a non-accrual basis. Non-performing assets consist of non-performing loans and leases plus other real estate owned. Non-performing assets at September 30, 2020 and December 31, 2019 totaled $51.3 million and $46.2 million, respectively, an increase of $5.1 million, or 11.2%, due to the increase in non-accrual loans.

Total non-accrual loans and leases increased by $6.9 million, or 19.1%, between December 31, 2019 and September 30, 2020 mostly due to a net increase of $8.8 million in commercial real estate loans. The U.S. government guaranteed portion of non-performing loans totaled $3.7 million at September 30, 2020 and $4.2 million at December 31, 2019.

Total OREO decreased from $9.9 million at December 31, 2019 to $8.2 million at September 30, 2020. The $1.7 million decrease in OREO resulted mostly from sales and valuation adjustments.

Total accruing loans past due decreased from $40.2 million at December 31, 2019 to $10.0 million at September 30, 2020. This represents a decrease of $30.2 million, or 75.1%, and can be attributed to decreases in commercial real estate loans, commercial and industrial loans, and construction, land development, and other land loans, primarily as a result of SBA CARES Act payments and payment deferrals granted to assist customers with their short-term cash flow needs during the COVID-19 pandemic. See Note 6 of our Unaudited Interim Condensed Consolidated Financial Statements, included in this report, for further information.

The following table sets forth the amounts of non-performing loans and leases, non-performing assets, and OREO at the dates indicated (dollars in thousands):

Acquired impaired loans (accounted for under ASC 310-30) that are delinquent and/or on non-accrual status continue to accrue income provided the respective pool in which those assets reside maintains a discount and recognizes accretion income. The aforementioned loans are characterized as performing loans based on contractual delinquency. If the pool no longer has a discount and accretion income can no longer be recognized, any loan within that pool on non-accrual status will be classified as non-accrual for presentation purposes.

Deposits

Our loan and lease growth is funded primarily through core deposits. We gather deposits primarily through each of our 56 branch locations in the Chicago metropolitan area and one branch in Brookfield, Wisconsin. Through our branch network, online, mobile and direct banking channels, we offer a variety of deposit products including demand deposit accounts, interest-bearing products, savings accounts, and certificates of deposit. We offer competitive online, mobile, and direct banking channels. Small businesses are a significant source of low cost deposits as they value convenience, flexibility, and access to local decision makers that are responsive to their needs.

Total deposits at September 30, 2020 were $4.8 billion, representing an increase of $662.7 million, or 16.0%, compared to $4.1 billion at December 31, 2019, driven by an increase in customer liquidity. Non-interest-bearing deposits were $1.7 billion, or 35.7% of total deposits, at September 30, 2020, an increase of $439.0 million, or 34.3%, compared to $1.3 billion at December 31, 2019, or 30.9% of total deposits. Core deposits were 89.9% and 83.1% of total deposits at September 30, 2020 and December 31, 2019, respectively.

Our average cost of deposits was 0.22% during the third quarter of 2020 compared to 0.94% during the third quarter of 2019. Our average cost of deposits was 0.43% during the nine months ended September 30, 2020 compared to 0.91% during the nine months ended September 30, 2019. These decreases were principally attributed to lower rates on interest-bearing deposits as a result the interest rate environment and an improved deposit mix. Our average non-interest bearing deposits to total deposits ratios were 35.4% during the third quarter of 2020 compared to 30.1% during the third quarter of 2019. We had $35.0 million and $41.0 million of brokered time deposits at September 30, 2020 and December 31, 2019, respectively. Our loan and lease to deposit ratio was 91.96% at September 30, 2020 compared to 91.56% at December 31, 2019.

Borrowed Funds

On June 26, 2020, the Company issued $50.0 million in 6.00% fixed-to-floating subordinated notes that mature on July 1, 2030. On August 3, 2020, the Company issued an additional $25.0 million. The subordinated notes bear a fixed interest rate of 6.00% until July 1, 2025 and a floating interest rate equal to a benchmark rate, which is expected to be three-month Secured Overnight Financing Rate (“SOFR”) plus 588 basis points thereafter until maturity (or earlier redemption). The Company may, at its option, redeem the notes, in whole or in part, on a semi-annual basis beginning on July 1, 2025, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required. The subordinated notes are intended to qualify as Tier 2 capital for regulatory capital purposes. The transaction resulted in debt issuance costs of approximately $1.7 million that will be amortized over 10 years.

In addition to deposits, we also utilize FHLB advances as a supplementary funding source to finance our operations. The bank’s advances from the FHLB are collateralized by residential and multi-family real estate loans and securities. At September 30, 2020 and December 31, 2019, we had maximum borrowing capacity from the FHLB of $2.0 billion and $1.9 billion subject to the availability of collateral, respectively. At September 30, 2020, the Company had $215.0 million of FHLB advances with a maturities ranging from October 2020 to May 2021.

The Company has the capacity to borrow funds from the discount window of the Federal Reserve System. The Company utilized the discount window to lower its cost of funds during the nine months ended September 30, 2020. There were no borrowings outstanding under the Federal Reserve Bank discount window line as of September 30, 2020 and December 31, 2019. The Company pledges loans as collateral for any borrowings under the Federal Reserve Bank discount window.

(1) | Our credit agreement with a third-party lender matures on October 2021. The line of credit bears interest at either the LIBOR Rate plus 195 basis points or the Prime Rate minus 75 basis points, based on our election, which is required to be communicate to the lender at least three business days prior to the commencement of an interest period. If we fail to provide timely notification, the interest rate will be Prime Rate minus 75 basis points.

Customer Repurchase Agreements (Sweeps)

Securities sold under agreements to repurchase represent a demand deposit product offered to customers that sweep balances in excess of the FDIC insurance limit into overnight repurchase agreements. We pledge securities as collateral for the repurchase agreements. Securities sold under agreements to repurchase decreased by $3.7 million, from $49.6 million at December 31, 2019 to $45.9 million at September 30, 2020.

Liquidity

We manage liquidity based upon factors that include the amount of core deposits as a percentage of total deposits, the level of diversification of our funding sources, the amount of non-deposit funding used to fund assets, the availability of unused funding sources, off-balance sheet obligations, the availability of assets to be readily converted into cash without undue loss, the amount of cash and liquid securities we hold and the re-pricing characteristics and maturities of our assets when compared to the re-pricing characteristics of our liabilities, the ability to securitize and sell certain pools of assets and other factors.

Our liquidity needs are primarily met by cash and investment securities positions, growth in deposits, cash flow from amortizing loan portfolios, and borrowings from the FHLB. For additional information regarding our operating, investing, and financing cash flows, see Consolidated Statements of Cash Flows in our Unaudited Interim Condensed Consolidated Financial Statements included elsewhere in this report.

As of September 30, 2020, Byline Bank had maximum borrowing capacity from the FHLB of $2.0 b illion and $1.4 billion from the Federal Reserve Bank (“FRB”). As of September 30, 2020, Byline Bank had open FHLB advances of $215.0 million and open letters of credit of $21.5 million, leaving us with available aggregate borrowing capacity of $930.9 m illion. In addition, Byline Bank had uncommitted federal fun ds lines available of $1 15.0 million and $968.7 million available under the Federal Reserve Bank discount window line at September 30, 2020.

As of December 31, 2019, Byline Bank had maximum borrowing capacity from the FHLB of $1.9 billion and $547.8 million from the FRB. As of December 31, 2019, Byline Bank had open advances of $490.0 million and open letters of credit of $20.8 million, leaving us with available aggregate borrowing capacity of $1.4 billion. In addition, Byline Bank had an uncommitted federal funds line available of $115.0 million and $547.8 million available under the Federal Reserve Bank discount window line at December 31, 2019.

On October 13, 2016, the Company entered into a $30.0 million revolving credit agreement with a correspondent bank. Through subsequent amendments, the revolving credit agreement was reduced to $15.0 million and the maturity was extended to October 8, 2021. The amended revolving line of credit bears interest at either the London Interbank Offered Rate (“LIBOR”) plus 195 basis points or the Prime Rate minus 75 basis points, based on the Company’s election, which is required to be communicated at least three business days prior to the commencement of an interest period. If the Company fails to provide timely notification, the interest rate will be Prime Rate minus 75 basis points. At September 30, 2020 and December 31, 2019, the line of credit had no outstanding balance.

There are regulatory limitations that affect the ability of Byline Bank to pay dividends to the Company. See Note 21 of our Consolidated Financial Statements, included in our Annual Report on Form 10-K for the year ended December 31, 2019 for additional information. Management believes that such limitations will not impact our ability to meet our ongoing short-term cash obligations.

We expect that our cash and liquidity resources will be generated by the operations of Byline Bank, which we expect to be sufficient to satisfy our liquidity and capital requirements for at least the next twelve months.

On April 21, 2020, Byline Bank entered into a Letter Agreement with the Federal Reserve Bank of Chicago that allows the Bank to access the Paycheck Protection Program Liquidity Facility (the “PPPLF”). Under the terms of the PPPLF, the Bank will pledge PPP loans funded under the CARES Act, to the Federal Reserve Bank of Chicago as collateral for available advances under the PPPLF. PPP loans pledged as collateral will be valued at an amount equal to the principal amount of the PPP loan outstanding at the time the PPP loan is pledged. Advances under the PPPLF will be an amount equal to the aggregate principal amount of PPP loans pledged by Byline Bank, will carry an interest rate of 0.35%, and mature on the maturity date of the corresponding PPP loans pledged as collateral. The Bank had $449.6 million outstanding under the PPPLF at September 30, 2020.

Capital Resources

Stockholders’ equity at September 30, 2020 was $794.7 million compared to $750.1 million at December 31, 2019, an increase of $44.6 million, or 5.9%. The increase was primarily driven by the increase in accumulated other comprehensive income reflecting the unrealized gains in our available-for-sale securities portfolio in addition to net income generated during the nine months ended September 30, 2020, less dividends declared.

The Company and Byline Bank are subject to various regulatory capital requirements administered by federal banking regulators. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by federal banking regulators that, if undertaken, could have a direct material effect on our financial statements.

Under applicable bank regulatory capital requirements, each of the Company and Byline Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Byline Bank must also meet certain specific capital guidelines under the prompt corrective action framework. The capital amounts and classification are subject to qualitative judgments by the federal banking regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Byline Bank to maintain minimum amounts and ratios of

81

CET1 Capital, Tier 1 capital and total capital to risk-weighted assets and of Tier 1 capital to average consolidated assets, (referred to as the “leverage ratio”), as defined under these capital requirements.

As of September 30, 2020, Byline Bank exceeded all applicable regulatory capital requirements and was considered “well-capitalized.” There have been no conditions or events since September 30, 2020 that management believes have changed Byline Bank’s classifications.

The regulatory capital ratios for the Company and Byline Bank to meet the minimum capital adequacy standards and for Byline Bank to be considered well capitalized under the prompt corrective action framework and the Company’s and Byline Bank’s actual capital amounts and ratios are set forth in the following tables as of the periods indicated (dollars in thousands):

The Company and Byline Bank must maintain a capital conservation buffer consisting of CET1 capital greater than 2.5% of risk-weighted assets above the required minimum risk-based capital levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. The conservation buffers for the Company and Byline Bank exceed the minimum capital requirement as of September 30, 2020.

Provisions of state and federal banking regulations may limit, by statute, the amount of dividends that may be paid to the Company by Byline Bank without prior approval of Byline Bank’s regulatory agencies. The Company is economically

82

dependent on the cash dividends received from Byline Bank. These dividends represent the primary cash flow from operating activities used to service obligations. For the nine months ended September 30, 2020 and year ended December 31, 201 9, the Company received $7.5 million and $13.5 million, respectively, in cash dividends from Byline Bank in order to pay the required interest on its outstanding junior subordinated debentures in connection with its trust pr eferred securities interest, dividends on the Series B preferred stock outstanding, and to fund other Company-related activities.

On November 1, 2019, the Company announced that its Board of Directors approved a stock repurchase program authorizing the purchase of up to an aggregate of 1,250,000 shares of the Company’s outstanding common stock. The shares may, at the discretion of management, be repurchased from time to time in open market purchases as market conditions warrant or in privately negotiated transactions, including pursuant to a Rule 10b5-1 plan, all as effected to the extent permitted by applicable law, including pursuant to the safe harbor provided under Rule 10b-18 of the Securities Exchange Act of 1934, as amended. The Company is not obligated to purchase any shares under the program, and the program may be discontinued at any time. The actual timing, number and share price of shares purchased under the repurchase program will be determined by the Company at its discretion and will depend on a number of factors, including the market price of the Company’s stock, general market and economic conditions and applicable legal requirements. The shares authorized to be repurchased represent approximately 3.3% of the Company’s currently outstanding common stock. Shares repurchased will be available for issuance under the Company’s equity incentive plans and for other general corporate purposes. The program will be in effect until December 31, 2020, unless terminated earlier. The Company repurchased 118,486 shares, or approximately $1.7 million, of stock during the first nine months of 2020 under this program, which were recorded as treasury shares on the trade date as a reduction in stockholders’ equity. This program was paused in March 2020.

On September 8, 2020, the Company announced that its Board of Directors declared a cash dividend on its common stock of $0.03 per share for the third quarter of 2020, which totaled $1.2 million. The dividend was paid on October 6, 2020 to stockholders of record on September 22, 2020.

Contractual Obligations

FHLB advances are fully described in Note 12 of our Unaudited Interim Condensed Consolidated Financial Statements, included elsewhere in this report. Operating lease obligations are in place for facilities and land on which banking facilities are located. See Note 14 of our Unaudited Interim Condensed Consolidated Financial Statements, included elsewhere in this report for additional information.

Off-Balance Sheet Items and Other Financing Arrangements

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit, commercial letters of credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The contractual or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments.

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 amount does not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by Byline Bank upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties). At September 30, 2020, commercial line of credit usage was $1.2 billion, or 57.2% of available lines compared to $1.2 billion, or 58.7% of available lines at December 31, 2019.

Letters of credit are conditional commitments issued by Byline Bank to guarantee the performance of a customer to a third-party. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

83

Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 1.25% to 1 8.00% and maturities up to 20 50. Variable rate loan commitments have interest rates ranging from 1.25% to 8.25% and maturities up to 20 48.

Our exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. We use the same credit policies in making commitments and conditional obligations as for funded instruments. We do not anticipate any material losses as a result of the commitments and standby letters of credit.

We enter into interest rate swaps that are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. We also enter into interest rate swaps with certain qualified borrowers to facilitate the borrowers’ risk management strategies and concurrently entered into mirror-image derivatives with a third party counterparty.

We recognize derivative financial instruments at fair value regardless of the purpose or intent for holding the instrument. We record derivative assets and derivative liabilities on the Consolidated Statements of Financial Condition within other assets and other liabilities, respectively. Because the derivative assets and liabilities recorded on the balance sheet at September 30, 2020 do not represent the amounts that may ultimately be paid under these contracts, these assets and liabilities are listed in the table below (dollars in thousands):

|  | September 30, 2020 |

GAAP Reconciliation and Management Explanation of Non-GAAP Financial Measures

Some of the financial measures included in our “Selected Financial Data” are not measures of financial performance in accordance with GAAP. Our management uses the non‑GAAP financial measures set forth below in its analysis of our performance:

| • | “Adjusted net income” and “adjusted diluted earnings per share” exclude certain significant items, which include incremental income tax benefit related to the reversal of the valuation allowance on our net deferred tax assets, incremental income tax benefit related to Illinois corporate income tax rate increases, incremental income tax expense or benefit related to federal corporate income tax reductions, impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses adjusted for applicable income tax. Management believes the significant items are not indicative of or useful to measure the Company’s operating performance on an ongoing basis.

| • | “Adjusted non-interest expense” is non-interest expense excluding certain significant items, which include impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses.

| • | “Adjusted efficiency ratio” is adjusted non-interest expense less amortization of intangible assets divided by net interest income and non-interest income. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Adjusted non-interest expense to average assets” is adjusted non-interest expense divided by average assets. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Adjusted return on average stockholders’ equity” is adjusted net income divided by average stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Adjusted return on average assets” is adjusted net income divided by average assets. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Non-interest income to total revenues” is non-interest income divided by net interest income plus non-interest income. Management believes that it is standard practice in the industry to present non-interest income as a percentage of total revenue. Accordingly, management believes providing these measures may be useful for peer comparison.

| • | “Pre‑tax pre‑provision net income” is pre‑tax income plus the provision for loan and lease losses. Management believes this metric is important due to the tax benefit resulting from the reversal of the net deferred tax asset valuation allowance, the decrease in the federal corporate income tax rate, and the increase in the Illinois state corporate income tax rate. The metric demonstrates income excluding the tax provision or benefit and the provision for loan and lease losses, and enables investors and others to assess the Company’s ability to generate capital to cover credit losses through a credit cycle.

| • | “Adjusted pre-tax pre-provision net income” is pre-tax pre-provision net income excluding certain significant items, which include impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Pre‑tax pre‑provision return on average assets” is pre-tax income plus the provision for loan and lease losses, divided by average assets. Management believes this metric is important due to the change in tax expense or benefit resulting from the recent decrease in the federal corporate income tax rate and the recent increase in the Illinois state income tax rate. The ratio demonstrates profitability excluding the tax provision or benefit and excludes the provision for loan and lease losses. “Adjusted pre-tax pre-provision return on average assets” excludes certain significant items, which include impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses.

| • | “Tangible common equity” is defined as total stockholders’ equity reduced by preferred stock and goodwill and other intangible assets. Management does not consider servicing assets as an intangible asset for purposes of this calculation.

| • | “Tangible assets” is defined as total assets reduced by goodwill and other intangible assets. Management does not consider servicing assets as an intangible asset for purposes of this calculation.

| • | “Tangible book value per common share” is calculated as tangible common equity, which is stockholders’ equity reduced by preferred stock and goodwill and other intangible assets, divided by total shares of common stock outstanding. Management believes this metric is important due to the relative changes in the book value per share exclusive of changes in intangible assets.

| • | “Tangible common equity to tangible assets” is calculated as tangible common equity divided by tangible assets, which is total assets reduced by goodwill and other intangible assets. Management believes this metric is important to investors and analysts interested in relative changes in the ratio of total stockholders’ equity to total assets, each exclusive of changes in intangible assets.

| • | “Tangible net income available to common stockholders” is net income available to common stockholders excluding after-tax intangible asset amortization.

| • | “Adjusted tangible net income available to common stockholders” is tangible net income available to common stockholders excluding certain significant items. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Return on average tangible common stockholders’ equity” is tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

| • | “Adjusted return on average tangible common stockholders’ equity” is adjusted tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

We believe that these non‑GAAP financial measures provide useful information to its management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, we acknowledge that our non‑GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP financial measures that we and other companies use. Management also uses these measures for peer comparison.

Item 3. Quantita ti ve and Qualitative Disclosures A bout Market Risk.

Our primary market risk is interest rate risk, which is defined as the risk of loss of net interest income or net interest margin because of changes in interest rates.

We seek to measure and manage the potential impact of interest rate risk. Interest rate risk occurs when interest-earning assets and interest-bearing liabilities mature or re-price at different times, on a different basis or in unequal amounts. Interest rate risk also arises when our assets, liabilities and off-balance sheet contracts each respond differently to changes in interest rates, including as a result of explicit and implicit provisions in agreements related to such assets and liabilities and in off-balance sheet contracts that alter the applicable interest rate and cash flow characteristics as interest rates change. The two primary examples of such provisions that we are exposed to are the duration and rate sensitivity associated with indeterminate-maturity deposits (e.g., non-interest-bearing checking accounts, negotiable order of withdrawal accounts, savings accounts and money market deposits accounts) and the rate of prepayment associated with fixed-rate lending and mortgage-backed securities. Interest rates may also affect loan demand, credit losses, and other items affecting earnings.

We are also exposed to interest rate risk through the retained portion of the U.S. government guaranteed loans we make and the related servicing rights. Our U.S. government guaranteed loan portfolio is comprised primarily of SBA 7(a) loans, virtually all of which are quarterly or monthly adjustable with the prime rate. The SBA portfolio reacts differently in a rising rate environment than our other non-guaranteed portfolios. Generally, when interest rates rise, the prepayments in the SBA portfolio tend to increase.

Our management of interest rate risk is overseen by our bank’s asset liability committee, and is chaired by Byline Bank’s Treasurer, based on a risk management infrastructure approved by our board of directors that outlines reporting and measurement requirements. In particular, this infrastructure sets limits and management targets, calculated monthly, for various metrics, including our economic value sensitivity, our economic value of equity and net interest income simulations involving parallel shifts in interest rate curves, steepening and flattening yield curves, and various prepayment and deposit duration assumptions. Our risk management infrastructure also requires a periodic review of all key assumptions used, such as identifying appropriate interest rate scenarios, setting loan prepayment rates based on historical analysis, non-interest-bearing and interest-bearing demand deposit durations based on historical analysis and the targeted investment term of capital.

We manage the interest rate risk associated with our interest-bearing liabilities by managing the interest rates and tenors associated with our wholesale borrowing sources and deposits from our customers that we rely on for funding. In particular, from time to time we use special offers on deposits to alter the interest rates and tenors associated with our interest-bearing liabilities. We manage the interest rate risk associated with our interest-earning assets by managing the interest rates and tenors associated with our investment and loan portfolios, from time to time purchasing and selling investment securities.

In addition, we manage our interest rate risk under different dynamic scenarios which we believe provides important information for our net interest income projections. This simulation allows us to monitor and seek to protect earnings in various interest rate cycles.

We utilize interest rate swaps to hedge our interest rate exposure on commercial loans when it meets our clients’ and Byline Bank’s needs. Typically, customer interest rate swaps are for terms of more than five years. As of September 30, 2020, we had a notional amount of $373.8 million of interest rate swaps outstanding. The overall effectiveness of our hedging strategies is subject to market conditions, the quality of our execution, the accuracy of our valuation assumptions, the associated counterparty credit risk and changes in interest rates.

We do not engage in speculative trading activities relating to interest rates, foreign exchange rates, commodity prices, equities or credit.

We are also subject to credit risk. Credit risk is the risk that borrowers or counterparties will be unable or unwilling to repay their obligations in accordance with the underlying contractual terms. We manage and control credit risk in the loan and lease portfolio by adhering to well-defined underwriting criteria and account administration standards established by management and overseen by the Bank’s loan committee. Written credit policies document underwriting standards, approval levels, exposure limits and other limits or standards deemed necessary and prudent. Portfolio diversification at the obligor, industry, product and/or geographic location levels is actively managed to mitigate concentration risk. In addition, credit risk management also includes an independent credit review process that assesses compliance with commercial, real estate and other credit policies, risk ratings, and other critical credit information. In addition to implementing risk management practices

91

that are based upon established and sound lending practices, we adhere to sound credit principles. We understand and evaluate our customers’ borrowing needs and capacity to repay, in conjunction with their character and history.

Evaluation of Interest Rate Risk

We use a net interest income simulation model to measure and evaluate potential changes in our net interest income. We run various hypothetical interest rate scenarios at least monthly and compare these results against a scenario with no changes in interest rates. Our net interest income simulation model incorporates various assumptions, which we believe are reasonable but which may have a significant impact on results such as: (1) the timing of changes in interest rates, (2) shifts or rotations in the yield curve, (3) re-pricing characteristics for market-rate-sensitive instruments on and off balance sheet, (4) differing sensitivities of financial instruments due to differing underlying rate indices, (5) the effect of interest rate limitations in our assets, such as floors and caps, (6) the effect of our interest rate swaps and (7) overall growth and repayment rates and product mix of assets and liabilities. Because of limitations inherent in any approach used to measure interest rate risk, simulation results are not intended as a forecast of the actual effect of a change in market interest rates on our results but rather as a means to better plan and execute appropriate asset-liability management strategies and manage our interest rate risk.

Potential changes to our net interest income in hypothetical rising and declining rate scenarios calculated as of September 30, 2020 is presented in the following table. The projections assume (1) immediate, parallel shifts downward of the yield curve of 100 basis points and immediate, parallel shifts upward of the yield curve of 100, 200 and 300 basis points and (2) gradual shift downward of 100 basis points over 12 months and gradual shifts upward of 100 and 200 basis points over 12 months. In the current interest rate environment, a downward shift of the yield curve of 200, and 300 basis points does not provide us with meaningful results. In a downward parallel shift of the yield curve, interest rates at the short-end of the yield curve are not modeled to decline any further than 0%. For the dynamic balance sheet and rate shift scenarios, we assume interest rates follow a forward yield curve and then increase it by 1/12th of the total change in rates each month for twelve months.

| Estimated Increase (Decrease) in Net Interest Income |
| Twelve Months Ending |  |  | Twelve Months Ending |
Change in Market Interest Rates as of September 30, 2020 | September 30, 2021 |  |  | September 30, 2022 |
Immediate Shifts |  |  |  |  |  |  |
+300 basis points |  | 16.2 | % |  |  | 23.9 | %
+200 basis points |  | 10.6 | % |  |  | 16.0 | %
+100 basis points |  | 4.7 | % |  |  | 7.4 | %
-100 basis points |  | (2.6 | )% |  |  | (4.4 | )%
Dynamic Balance Sheet and Rate Shifts |  |  |  |  |  |  |
+200 basis points |  | 5.5 | % |  |  |  |
+100 basis points |  | 2.2 | % |  |  |  |
-100 basis points |  | (1.3 | )% |  |  |  |

The results of this simulation analysis are hypothetical, and a variety of factors might cause actual results to differ substantially from what is depicted. For example, if the timing and magnitude of interest rate changes differ from those projected, our net interest income might vary significantly. Non-parallel yield curve shifts such as a flattening or steepening of the yield curve or changes in interest rate spreads, would also cause our net interest income to be different from that depicted. An increasing interest rate environment could reduce projected net interest income if deposits and other short-term liabilities re-price faster than expected or faster than our assets re-price. Actual results could differ from those projected if we grow assets and liabilities faster or slower than estimated, if we experience substantially different repayment speeds in our loan portfolio than those assumed in the simulation model, if we experience a net outflow of deposit liabilities or if our mix of assets and liabilities otherwise changes.

These simulation results do not contemplate all the actions that we may undertake in response to potential or actual changes in interest rates, such as changes to our loan, investment, deposit, funding or hedging strategies.

Item 4. Controls and Procedures.

The Company’s management, including our President and Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)), as of the end of the period covered by this report. Based on such evaluation, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of September 30, 2020, the Company’s disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and is accumulated and communicated to the Company’s management, including our President and Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting during the quarter ended September 30, 2020, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.
