Message from the CEO and President

April 1, 2025

Dear Fellow Shareholders,

In a rapidly changing global marketplace, CSG continues to relentlessly execute our value-creating strategy that prioritizes fantastic operating discipline, strong double-digit free cash flow growth, and investor friendly capital allocation.

Since joining the company in early 2016, I have held my CSG stock on the way to becoming a top ten shareholder because I believe CSG offers each of us excellent and sustained shareholder returns. CSG’s Board of Directors and leadership team will continue to put our money behind the commitments we make to you.

Team CSG closed 2024 with a record-setting Q4 that we expect will further accelerate our business momentum heading into 2025 and beyond. Our continued success stems from several earn-the-right-to-grow foundations.

■ | CSG’s growth is powered by a culture-first, inclusive operating model that wins with the best talent globally. We grow and reward leaders around the world who demonstrate exceptional CSG leadership traits defined as humble, company-first leaders who possess a ferocious determination to constantly deliver better and better business results no matter what. Our people thrive on managing competing priorities in a constrained environment.
■ | CSG’s innovation enables us to simplify complex monetization and customer engagement processes in a wide variety of industry verticals with integrated, domain-specific technology. As a result, any brand in any industry with recurring customer relationships can be more profitable by selling, engaging, and monetizing better with integrated CSG technology that embeds data-driven real-time workflows.
■ | CSG’s sticky value proposition, global direct sales team, and increasingly channel-driven go-to-market efforts are fueling excellent new sales wins globally. Equally exciting is the level of revenue diversification we are achieving with 30% of revenue coming from exciting new industry verticals like retail, financial services, insurance, healthcare, and government, just to name a few.
■ | CSG’s strong operating discipline is expanding our gross margins and profitability, which we expect to convert into sustained double-digit free cash flow growth in the coming years. We believe CSG is just beginning to see the longer-term benefits of a shift toward better revenue mix as we grow SaaS revenue faster in exciting new industry verticals combined with quarter-in, quarter-out efficiency improvements.

Message from the CEO and President

As we consistently deliver better organic financial results, we also aspire to reward investors with disciplined value-creating capital allocation that balances returning capital to shareholders with good accretive acquisitions that strengthen our market leadership. With the compounding effect of more inorganic SaaS scale, we think that investors could benefit from an expanded CSG earnings multiple as we look to become more asset-light and generate even faster inorganic profit and free cash flow growth in the years ahead.

Being the best in the world at simplifying complex monetization and customer engagement with sticky, industry-leading, domain-specific CSG technology is never easy.

We are extremely grateful to our customers for the decades long trust they place in us, and to our over 5,800 CSG employees around the world who turn these bold expectations into reality every day.

Sincerely,

Brian A. Shepherd

President and Chief Executive Officer

Director Independence and Experience

The Board has determined that each director except Mr. Shepherd, our President and CEO, is an “independent director” as defined in the applicable rules of The Nasdaq Stock Market, Inc. (“Nasdaq”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”). We believe that having a Board consisting of predominantly independent, experienced directors with independent oversight by a non-executive Chair (as described below) is in the best interests of the Company and its shareholders.

It is critical that we recruit and nominate independent directors who help achieve the goal of a well-rounded, diverse Board that functions respectfully as a unit. Our Board includes directors who have historical institutional knowledge of the Company and the markets we serve, complemented by directors who bring diversity of experience, perspectives, qualifications, and leadership to address the issues facing the Company. Our Board has made a concerted effort to recruit new directors to achieve the right blend between continuity and new perspectives. The following charts represent director independence, tenure, and diversity, assuming the three nominees are elected at the Annual Meeting.

Corporate Governance and Board of Directors

Overview

As described in this section, the Board has formalized several policies, procedures, and standards of sound corporate governance. We continue to monitor best practices and legal and regulatory developments with the view of refining our governance policies and procedures, as appropriate. The Board encourages you to visit the governance page on our website at ir.csgi.com/governance/documents-and-charters, which provides information about our corporate governance practices and includes the following documents:

■ | Board Committee Charters
■ | Code of Ethics and Business Conduct

■ | Corporate Governance Guidelines
■ | Stock Ownership Policy

We will disclose on our website any amendments to our Code of Ethics and Business Conduct and any waiver of a provision of our Code of Ethics and Business Conduct that is required to be disclosed under applicable SEC rules.

Information contained on, or accessible through, our website or any other website is not part of, nor incorporated by reference in, this proxy statement.

Insider Trading Policy

We have adopted an Insider Trading Policy governing the purchase, sale, and other dispositions of CSG's securities by our officers, directors, employees, consultants, or contractors who have contact with material nonpublic information, immediate family members of each of the foregoing, as well as the Company itself (“Covered Parties“). Pursuant to our Insider Trading Policy, no Covered Party may engage in any transaction involving CSG's securities during any period when the Covered Party is aware of material nonpublic information concerning CSG. Our Insider Trading Policy also prohibits Covered Parties from engaging in any transaction involving CSG's securities except during an Open Trading Window (as defined in the policy). We believe our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws. A copy of our Insider Trading Policy is filed as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Board Leadership Structure

The Board does not have a policy regarding separation of the roles of CEO and Chair of the Board and believes it is in the best interests of the Company to determine the appropriate leadership structure based on current circumstances.

Mr. Cooper has served as Chair of the Board since 2022 and will retire at the conclusion of the Annual Meeting and is not standing for re-election. Following a careful and thorough succession process, Marwan Fawaz, an independent director, was selected by the Board to succeed Mr. Cooper as Chair of the Board, subject to Mr. Fawaz being re-elected at the Annual Meeting. Mr. Fawaz was selected for this role by the Board based on his extensive experience in the industry and his many years of service on CSG's Board, and his appointment will ensure continuity in the Company's governance philosophy. The Board has determined that an independent director serving as Chair is in our best interests at this time. Our Board believes that an independent director serving as Chair ensures that the independent directors have a significant role in the active oversight of our business, including overseeing risk management, setting agendas, and establishing Board priorities and procedures. In the future, if the Board believes it would be in the best interests of the Company and our shareholders, the Board may decide that one person should serve as both CEO and Chair of the Board.

Risk and Compliance Oversight

Risk and Compliance Oversight

Overall Risk Approach

The Board is responsible for oversight of our risks, including establishing our risk appetite and overseeing our risk management framework. The Board recognizes that effective risk oversight is important to the success of our strategy and is an integral part of its fiduciary duties to the Company and our shareholders. The Board believes well-considered risk-taking is a critical component of innovation and effective leadership but also recognizes that imprudently accepting risks or failing to appropriately identify and mitigate risks could negatively impact our business and shareholder value. The Board therefore seeks to foster a risk-aware culture that conforms to an established risk appetite framework while encouraging thoughtful risk-taking in pursuit of the Company’s strategic initiatives.

The Board exercises its risk oversight primarily through the Company's executive management, the Audit Committee, and the Cybersecurity Committee, as described below. The Board believes our current leadership structure facilitates its oversight of risk by combining independent leadership through the Board and the Audit Committee, with the experience of the Company's executive management team members, who each have intimate knowledge of our business, industry, and challenges.

Board Committee Risk Oversight

The Audit Committee receives regular reports on risk-related matters from members of executive management, including:

■ | The Chief Compliance Officer, who reports functionally to the Chief Legal Officer and administratively to the Audit Committee, prepares reports summarizing compliance risks, issues, and activities.
■ | The Head of Internal Audit, who reports functionally to the Audit Committee and administratively to the Chief Accounting Officer, prepares reports summarizing the results of internal audits, our enterprise risk program, and the related risks, issues, and activities.

Our Compensation Committee and SSG Committee monitor risks in their respective areas of responsibility and keep the Board informed of any specific risks through regular reports.

The full Board receives a report on cybersecurity on a quarterly basis from our Chief Information Officer (“CIO“) and Chief Information Security Officer (“CISO“), and the Cybersecurity Committee of the Board convenes as necessary to oversee critical or emerging cybersecurity risks and to ensure alignment on approach. Additionally, the Cybersecurity Committee reviews the outcomes of our regular tabletop exercises with our CIO and CISO and ensures that lessons learned have been incorporated into the overall strategy. For additional information on our cybersecurity risk oversight, please see Part I, Item 1C of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Risk Assessment and Mitigation Program

We maintain a formal risk assessment and risk mitigation program. Our executive officers, in conjunction with members of our risk and security organizations, review this program periodically throughout the year. This program has three goals: (i) identify those risks that are most likely to affect our business; (ii) assign individual executives to be responsible for monitoring and mitigating each of those risks; and (iii) provide a formal mechanism for the assigned executives to report back periodically on the adequacy and effect of mitigation efforts. The Audit Committee and the Board regularly review the results of this program.

Annual Board Evaluation Process

Annual Board Evaluation Process

The Board is committed to a rigorous annual self-evaluation. The Chair of the SSG Committee coordinates an annual evaluation process that alternates between a self-evaluation survey and an evaluation conducted by an independent, third-party consultant. In 2024, the Chair of the SSG Committee led the self-evaluation process. The results of the annual evaluation were provided to the full Board for their consideration. Regular Board evaluations will continue to include a Board survey process.

Board Refreshment Policies

The Board does not have a mandatory retirement age or term limits because we believe such fixed rules do not recognize the continuing contributions of directors who have developed experience with, and insight into, the Company. However, the Board understands there is value in regularly reviewing and refreshing its composition, if appropriate, and continually evaluating the effectiveness of its directors as described herein.

What We Look for in Director Nominees

In recommending nominees for election as directors, the SSG Committee reviews the present composition of the Board to determine if additional qualities, skills, and expertise would help the Board and its committees properly discharge their responsibilities. When there is a need, the SSG Committee utilizes the services of executive search firms with well-established board practices to help identify and recruit qualified director nominees. When identifying and assessing a candidate’s qualifications, the SSG Committee considers, among other things:

■ | the candidate’s independence, judgment, skills, background, and experience;
■ | the candidate’s ability and willingness to devote the required amount of time to serve as a Board member and as a member of one or more Board committees;

■ | the candidate’s other business and professional commitments and potential conflicts of interest; and
■ | the number and type of other boards on which the candidate serves.

Although we do not have a written policy on director diversity, the SSG Committee values and seeks directors who encompass many different attributes, including background, experience, skills, substantive expertise, gender, ethnicity, geography, and education. Our Board is particularly interested in assembling a group of directors who understand the needs of our customers and also have experience in operations, finance, accounting, marketing, human resources, sales, and domestic and international business—particularly in the technology and communications service provider industries. We also consider whether nominees are active or retired executive officers of public or private companies and whether they have ever served on the board of a public company.

We expect Board members to display the personal attributes necessary to be effective directors: integrity, sound judgment, independence, and ability to collaborate. We believe the current members of our Board have an optimal variety of business and personal experiences, backgrounds, and expertise, and that they share the personal attributes described above. This year, upon the recommendation of the SSG Committee, the Board appointed Ms. Samantha Greenberg. Ms. Greenberg, who is standing for election for the first time since her appointment, was recommended by an independent third-party search firm and appointed to the Board in May 2024. For more information regarding the skills and experience of our directors, including Ms. Greenberg, please see the directors’ biographies, which begin on page 15, Proposal 1 — Election of Directors.

Consideration of Director Recommendations by Shareholders

The SSG Committee will consider director recommendations by our shareholders in the same manner that the Committee considers other director candidates.

Our Secretary will forward qualifying recommendations from shareholders to the Chair of the SSG Committee for further review and consideration. For shareholders who wish to nominate a director at a meeting, our bylaws provide that shareholder nominations for election to the Board are subject to certain advance notice and informational requirements. See Shareholder Proposals for additional requirements and information. Shareholders may obtain a copy of the relevant bylaw provisions from our Secretary at CSG Systems International, Inc., 169 Inverness Drive West, Suite 300, Englewood, Colorado 80112.

Board Committees

Audit Committee

Number of Meetings in 2024: 9

The Audit Committee’s primary purposes are to oversee our accounting and financial reporting processes, the audits of our financial statements, and our risk and compliance management programs (excluding management of cybersecurity risk, which rests with the Cybersecurity Committee and the Board). All members of the Audit Committee satisfy all Nasdaq and SEC requirements applicable to audit committee members, and all members of the Audit Committee are “independent” as defined by the SEC and Nasdaq rules and regulations. The Board has determined that Mr. Barnes, Mr. Cooper, Mr. Tavares, Ms. Yang, and Ms. Greenberg are “audit committee financial experts” as defined by applicable SEC rules.

Compensation Committee

Number of Meetings in 2024: 5

The Compensation Committee’s primary purposes are to review and recommend management compensation and benefit policies, and to evaluate the performance and recommend the compensation of our executive officers. In addition, the Compensation Committee has independent authority to administer and grant equity awards (under our equity plans) and annual performance bonuses for executive officers, other than the CEO. The Compensation Committee is also responsible for ongoing risk oversight and risk evaluation of our compensation policies and practices for employees generally. The Compensation Committee may delegate any of its responsibilities to a subcommittee or the Chair of the Compensation Committee. The Compensation Committee may also delegate to one or more of our officers the authority to grant awards to non-executive officers and employees under our equity compensation plans. Since 2022, the Compensation Committee has delegated to the CEO the authority to grant equity awards to non-executive officers and other employees.

All members of the Compensation Committee satisfy all Nasdaq and SEC requirements applicable to compensation committee members, and all members of the Compensation Committee are “independent” as defined by the SEC and Nasdaq rules and regulations.

Determining Executive Officer Compensation and Use of Independent Executive Compensation Consultants

To assist the Compensation Committee with its responsibilities, the Compensation Committee retains an independent executive compensation consultant, consults with our CEO (other than with respect to compensation decisions for the CEO) and our Chief Experience Officer, and draws upon the extensive business experience of its members. The Compensation Committee directs the independent executive compensation consultant to prepare a comprehensive formal assessment of the competitiveness of our executive officer compensation program, including a comparison of the principal components of our program (base salaries, performance bonuses, and equity awards) and other compensation program elements with those of a peer group of other public companies as well as industry best practices. The Compensation Committee considers this assessment and other data provided by the independent executive compensation consultant in arriving at its decisions or recommendations to the Board with respect to base salaries, performance bonuses, long-term incentives, and other compensation program elements for our executive officers. For additional information about our executive compensation program, processes, and procedures, see Compensation Discussion and Analysis.

The Compensation Committee periodically evaluates the qualifications of its independent executive compensation consultant. During 2024, Semler Brossy, a national compensation consulting firm, provided executive compensation guidance to the Compensation Committee. Semler Brossy reported directly to the Compensation Committee Chair, and also coordinated with management for data collection and other work streams as directed by the Committee. Semler Brossy did not provide any other services to us in 2024.

During 2024, the Compensation Committee requested information from Semler Brossy, our executives, and our Board members in order to assess the independence of both of the Compensation Committee’s executive compensation consultant and to determine whether their work raised any conflict of interest. Based on the information provided, the Compensation Committee determined that Semler Brossy was independent and that its work did not raise conflicts of interest.

Risks Related to Compensation Policies and Practices for All Employees

The Compensation Committee does not believe that risks arising from our compensation policies and practices are reasonably likely to have a material adverse effect on the Company. A number of the factors considered by the Compensation Committee when it develops executive compensation recommendations have the effect of mitigating risk. Additionally, executive officers and senior management regularly review our employee compensation policies and practices, including the elements of our compensation programs, to determine whether any element or program design encourages excessive risk-taking.

For more information about the factors we consider that reduce the likelihood of excessive risk-taking, see Risk and Compliance Oversight and Compensation Discussion and Analysis.

Sustainability, Social Responsibility, and Governance Committee

Number of Meetings in 2024: 4

The SSG Committee is the Company's nominating committee. Its primary purposes are to identify individuals qualified to become Board members, recommend to the Board nominees for election as directors, recommend directors for appointment to Board committees, evaluate the Board’s performance in conjunction with the formal and structured annual Board evaluation process, review and recommend the compensation of our directors, including awarding of equity to our non-employee directors, review CEO succession planning, oversee and support company commitments to Environmental, Social, and Governance (“ESG”) and other public policy initiatives as they pertain to business objectives and long-term strategy, and develop and recommend for Board approval our Corporate Governance Guidelines and Code of Ethics and Business Conduct.

All members of the SSG Committee are “independent” as defined by the SEC and Nasdaq rules and regulations.

Cybersecurity Committee

The Cybersecurity Committee convenes on an ad hoc basis to address critical or emerging cybersecurity concerns and to ensure alignment in the Company's approach to these issues. The Cybersecurity Committee’s primary purpose is to provide oversight, guidance, and recommendations to the Board on cybersecurity matters, including data responsibility objectives, strategies, capabilities, initiatives, and risk assessment and mitigation protocols for the Company. The members of this Committee have specific cybersecurity experience. Prior to February 2024, the Board managed cybersecurity matters through the Audit Committee and a Cybersecurity Subcommittee.

All members of the Cybersecurity Committee are “independent” as defined by the SEC and Nasdaq rules and regulations.

Director Attendance at Meetings

Director Attendance at Meetings

During 2024, the Board held nine meetings. Each director attended at least 75% of the aggregate of the total number of meetings of the Board and of the committees on which they served. In addition, during 2024, the Board held three executive sessions during which only independent directors were present. The Board expects to continue to conduct executive sessions limited to non-employee directors, at least twice a year. Our non-employee directors may schedule additional executive sessions at their discretion.

Historically, most shareholders vote by proxy. Accordingly, directors are not required to attend our annual meetings. We expect, but do not require, employee directors to attend if their schedules permit, and non-employee directors are welcome to attend if they wish. All of our current directors attended our 2024 Annual Meeting. The Board scheduled the Annual Meeting to coincide with a regular quarterly meeting of the Board so that all members could more easily attend the Annual Meeting.

Communications with the Board

We invite shareholders or any other interested party to send written communications to the Board or to individual Board members. Please send your letter in care of the Secretary of the Company at the address of our principal offices as shown on the first page of this proxy statement or via email to our Investor Relations Department at john.rea@csgi.com. Any letter that relates to accounting, internal accounting controls, or auditing matters will be forwarded to the Chair of the Audit Committee. All other appropriate letters will be forwarded to the entire Board or to the individual Board member(s) to whom they are addressed. If a letter relates to publicly available information about the Company or our stock, the Secretary will respond to the writer directly. If a letter is primarily commercial in nature or, in the Secretary’s opinion, relates to an improper or irrelevant topic, the Secretary will make a record of it, but will not transmit the communication to the Board.

Social

Attracting, growing, and retaining a future-ready workforce is critical to our success. CSG believes that inclusive companies that attract and grow employees with many different perspectives outperform others. As a result, this principle is reflected in how we lead, work, and deliver exceptional value to our customers.

Our global teams—with employees represented in over 20 countries—reflect a rich tapestry of backgrounds, cultures, identities, and experiences that celebrates the uniqueness of over 5,800 CSGers. We create this richness by building diverse talent pipelines and creating opportunities for mentoring, coaching, sponsorship, and development, including our Employee Belonging Groups and our special equity and mentorship programs to reward our top performing emerging leaders.

Ultimately, we aspire to be the employer of choice for growth-minded individuals who want to create a more future-ready company, community, and industry. We believe that with a culture-first, people-first philosophy, we will consistently do right by our employees, our customers, and our shareholders.

Proposal 1 — Election of Directors

The Board is divided into three classes with staggered terms. The terms of our Class I Directors will expire at the Annual Meeting.

The Board, upon recommendation of the SSG Committee, has nominated Mr. Conley, Mr. Fawaz, and Ms. Greenberg to be re-elected as Class I Directors at the Annual Meeting. In addition, Mr. Cooper, a Class I Director, has announced that he is retiring in connection with the Annual Meeting and, as a result, the number of directors to serve on our Board following the Annual Meeting will be ten.

Unless a proxy is marked otherwise, the person acting under the accompanying proxy will vote to elect Mr. Conley, Mr. Fawaz, and Ms. Greenberg as the Class I Directors to serve until the 2028 annual meeting of shareholders.

Compensation of Directors

After consultation with the Compensation Committee’s independent executive compensation consultant, including an analysis of peer and market practices, the Board sets the director compensation program to align with similar companies in our industry. Periodically, our Board of Directors reviews the competitiveness of our compensation program for non-employee directors.

Based on such analysis, supported by the Compensation Committee’s independent executive compensation consultant, the SSG Committee decided not to change our non-employee director compensation program in 2024.

Our non-employee director compensation program consists of the following:

Cash Compensation(1)
Annual retainer for non-employee director service(2) |  | $ | 75,000
Additional annual retainer for Chair of the Board |  | $ | 75,000
Additional annual retainer for committee member service(3) |  | $ | 7,500
Additional annual retainer for committee chair service: |  |  |
Audit Committee |  | $ | 16,000
Compensation Committee |  | $ | 16,000
Sustainability, Social Responsibility, and Governance Committee |  | $ | 10,000
Equity Compensation(4)
Annual equity |  | $ | 200,000

(1) | Cash retainers are paid in advance in quarterly installments, subject to such non-employee director’s continued service on the Board.
(2) | A director who is an officer or employee of the Company does not receive additional compensation for serving as a director or committee member. Mr. Shepherd is the only current officer or employee of the Company who serves as a director, and he does not currently serve on any Board committee.
(3) | Each non-employee director who serves as a committee member is entitled to only one committee member retainer irrespective of the number of committees on which such non-employee director serves.
(4) | Each non-employee director receives an annual equity grant in the form of restricted stock as determined by the SSG Committee and approved by the Board, which vests on the day immediately preceding the first annual general meeting of the Company’s shareholders occurring after the award date. Numbers of shares awarded are calculated by dividing the annual equity grant amount by the twenty-day trailing average of our common stock closing share price on Nasdaq (“20-day Trailing Average”), calculated twenty consecutive trading days prior to the award date.

(1) | This column reflects the aggregate grant date fair value of 4,723 shares of restricted stock granted to each non-employee director during the year computed in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 718 (“ASC Topic 718”). The value reported excludes the impact of estimated forfeitures, if any. Assumptions used to determine these amounts are set forth in Note 13 of our 2024 Form 10-K.
(2) | The aggregate number of restricted stock awards that had not vested as of December 31, 2024, was 4,723 shares for each non-employee director. No other awards held by non-employee directors were outstanding as of that date.

Share Ownership Policy

In April 2022, the Board established a robust share ownership policy for our non-employee directors, CEO, and Executive Vice Presidents, which was updated in February 2024. Those covered by the policy must attain the minimum ownership level within five years of April 1, 2022 or within five years of their date of appointment, whichever is later. Individuals may not sell any shares of CSG stock that they own, including any net shares received upon the exercise of options or vesting of restricted stock or restricted stock units until the ownership requirements are met, subject to a limited number of exceptions.

The Board and management believe that share ownership aligns the interests of the Company’s non-employee directors, CEO, and Executive Vice Presidents with the interests of shareholders, promotes sound corporate governance, and demonstrates a commitment by leadership to the long-term future of the Company. All non-employee directors, the CEO, and Executive Vice Presidents are in compliance with the ownership policy, subject to applicable grace periods and other transfer limitations.

Delinquent Section 16(a) Reports

Below is a summary of the required minimum share ownership levels:

Role |  | Minimum Ownership Level(1) |  | Compliance Status as of December 31, 2024
Non-Employee Board Directors |  | 5x annual cash retainer |  | 100%
CEO |  | 6x base salary |  | 100%
Executive Vice Presidents |  | 3x base salary |  | 100%

(1) | Stock value is determined by using a “20-day Trailing Average” ending on the applicable measurement date. Stock ownership for the purpose of compliance with these guidelines includes: shares purchased on the open market, shares obtained through the employee stock purchase plan, shares obtained through stock option exercise (and not thereafter sold), and vested shares of restricted stock or restricted stock units.

Management conducts an annual assessment to determine whether an individual has met the applicable requirements. Failure to comply with the share ownership guidelines will result in consequences to be determined by the Compensation Committee for the CEO, Executive Vice Presidents or the SSG Committee for non-employee directors.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our Section 16 officers (as defined in the applicable regulations), directors, and persons who beneficially own more than 10% of our common stock, to file certain reports of ownership and changes of ownership of our equity securities with the SEC. Officers, directors, and the shareholders who beneficially own more than 10% of such shares are required by SEC regulation to furnish to the Company copies of all Section 16(a) forms that they file.

Based solely on our review of the copies of such forms filed with the SEC and written representations from certain reporting persons, we believe that all filings required by our officers, directors, and persons who beneficially own more than 10% of our common stock were timely filed for the year ending December 31, 2024, except the inadvertently late filings of Michael Woods and Hai Tran. Mr. Woods did not timely file a Form 4 to report one transaction from February 29, 2024, but such form was subsequently filed on March 12, 2024. Additionally, Mr. Tran and Mr. Woods each did not timely file a Form 4 to report one transaction from March 28, 2024, but such forms were subsequently filed on April 3, 2024.

■ | Expanded our leadership position in the North American PayTV and broadband market by continuing to deepen our relationships with these customers and deploy new solutions.
■ | Announced a watershed contract renewal with Comcast, extending our agreement through 2030 and expanding on a 35+ year relationship to continue to provide mission-critical support for Comcast’s Triple-Play broadband subscribers and other areas of Comcast’s business.
■ | Announced record new logo wins and extensions in 2024 with big global brands, including Telenor Denmark, Lyse, Formula1, and Zain Sudan.
■ | Continued our industry diversification efforts by increasing revenue from verticals outside the Communications Service Provider industry to approximately 30% of our revenue, up from approximately 28% in 2023.
■ | Drove innovation and technology leadership with $158 million of research and development investments to enable a growing list of companies around the world to provide a more personalized customer experience and monetize new digital products and services.
■ | Returned $102 million to shareholders through a combination of $35 million of declared dividends and $68 million in common stock repurchases. We also increased our 2024 dividend by 7% from the prior year, representing our 12th consecutive year of increasing our dividend payout. CSG has proudly returned approximately $540 million to shareholders over the past five years.
■ | CSG’s Board of Directors authorized an additional $100 million share repurchase program in August 2024 to support continued shareholder returns.

2024 Executive Compensation Highlights

Highlights of our 2024 Executive Compensation Program include:

■ | Market-Aligned, Performance-Driven Compensation Programs. As in prior years, our executive compensation program was designed to compensate our NEOs in a manner that aligned with market practice and shareholder interests, and consisted of three primary components: base salary, cash annual bonus, and long-term equity incentives. Our annual bonus was based on objective and quantifiable revenue less transaction fees and non-GAAP operating margin goals, and our long-term incentives consisted of a majority of performance-based awards on multi-year revenue and non-GAAP EPS goals as well as relative total shareholder return (“rTSR”) compared to the Russell 2000.
■ | Strong Say-on-Pay Support. Our 2024 Say-on-Pay proposal was approved by 97.5% of shareholders. Shareholder engagement is a key value and a significant factor in determining our compensation programs, and we are pleased with the positive response from shareholders to enhancements we have made in recent years.
■ | Pay for Performance Alignment. Our financial performance resulted in a 2024 annual performance bonus achievement at 60.3% of target. Our NEOs earned an overall weighted achievement of 129.4% of target shares for our 2023 two-year performance-based LTI award’s financial objectives, and 100% for our 2022 three-year performance-based LTI award’s rTSR objectives. We view these outcomes as indicative of our rigorous goal-setting process.
■ | Long-Term CEO Performance Award. In December 2024, our Board of Directors awarded our CEO with a five-year long-term incentive equity award that vests based on rigorous predetermined stock price thresholds over a five-year period, subject to time-based vesting conditions. The intention of this award was to create additional incentives beyond the goals and time frames of our ongoing performance-based LTI program and equity awards and to explicitly tie an additional portion of our CEO’s compensation to the successful execution of our long-term strategy and significant value creation for our shareholders. The award reflects the CEO’s pivotal role in executing our strategic long-term vision.

Executive Summary

Compensation Mix and Pay-for-Performance Compensation Program

A majority of the total target compensation for our NEOs was based on the achievement of key financial and operational measures under our annual performance bonus program and performance-based LTI awards.

CEO |  | Other NEOs - Average

Our NEOs achieved a payout of 2024 annual performance bonus along with 2022 and 2023 performance-based LTI awards vesting in 2024 under our executive compensation program as follows:

■ | 60.3% of target under the annual performance bonus program for 2024;
■ | 100.0% of target shares vest under the 2022 three-year market performance-based LTI awards; and

■ | 129.4% of target shares vest under the 2023 two-year financial performance-based LTI awards.

Annual Performance Bonus Program |  | Performance-Based |  | Provide an annual bonus opportunity that is tied to predetermined Company performance goals and achievement of individual performance objectives to ensure focus on annual financial and operating results |  | 11-21% |  | Based on Revenue less Transaction Fees and non-GAAP adjusted operating margin, and subject to a People & Culture Modifier, in addition to individual performance. Resulted in a 2024 bonus payout equal to 60.3% of target.
LTI Program-Performance-Based Awards |  | Performance-Based |  | Provide compensation and ownership opportunity based on the achievement of ambitious, multi-year strategic and shareholder goals(1) |  | 30-55% |  | 2024 performance-based LTI awards are tied to multi-year non-GAAP EPS and Revenue goals, as well as rTSR vs. the Russell 2000 Index

Summary of Say-on-Pay and Responsiveness

Shareholder engagement and feedback are key factors and a significant part of our ongoing review of corporate governance and executive compensation practices. We are committed to actively seeking feedback from our shareholders to foster constructive dialogue on our programs and the decision-making process behind them.

In 2024, we received strong Say-on-Pay support, where shareholders owning 97.5% of our shares approved our 2024 Say-on-Pay proposal. While we are pleased with the positive response from our shareholders to the enhancements we have made in recent years, we believe ongoing dialogue with our shareholders regarding executive compensation is important. As such, we continue to solicit and consider feedback from our shareholders as part of our regular outreach efforts.

How the Compensation Committee Determines Executive Compensation

How the Compensation Committee Determines Executive Compensation

The Compensation Committee evaluates and determines the base salary for each of our NEOs, other than the CEO, as well as the performance measures and target levels for the annual performance bonus program and performance-based LTI awards for the current year. The Compensation Committee evaluates and recommends to the Board the base salary, performance measures, and target levels for the annual performance bonus program and performance-based LTI awards for the current year for the CEO.

When making compensation decisions and recommendations, the Compensation Committee considers the following key factors:

■ | Competitive peer group and market information and guidance provided by the Compensation Committee’s independent executive compensation consultant
■ | Our financial and operational performance compared to the performance targets for our incentive plans
■ | Progress on key strategic initiatives
■ | Individual performance reviews and compensation recommendations provided by the CEO
■ | Compensation Committee and Board evaluations, both formal and informal, of the NEOs, including the CEO

Role of the Independent Executive Compensation Consultant and Management

The Compensation Committee has sole authority and discretion to retain and terminate executive compensation consultants, independent legal counsel, and other advisers to help the committee perform its responsibilities. It also has the sole authority to approve the fees, scope, and other terms of engagement with its executive compensation consultant and other advisers, with full funding provided by the Company. The Compensation Committee is responsible for determining the independence of its executive compensation consultant and other advisers. Management is available on request to assist the compensation consultant by providing historical pay data and perspective on our competitive environment for recruiting managerial talent.

The Compensation Committee has retained Semler Brossy as its independent compensation consultant. In 2024, Semler Brossy attended Compensation Committee meetings, including executive sessions, and provided counsel on various compensation-related matters, including peer group selection, competitive market assessments, and insights into market trends in executive compensation and structuring LTI awards. The Compensation Committee assessed the independence of Semler Brossy pursuant to SEC rules and concluded that their work did not raise any conflicts of interest.

Role of Benchmarking in Determining Compensation and Peer Group

How We Use Peer Group Information

To assist the Compensation Committee in establishing 2024 compensation for the NEOs, our executive compensation consultant provided a competitive assessment using peer group compensation information for the primary elements of our NEO compensation packages. Along with our executive compensation consultant, the Compensation Committee analyzed and assessed peer group data for roles corresponding to and closely aligned with the roles of our NEOs.

The Compensation Committee recognizes that peer group comparisons may not be perfectly aligned because the responsibilities at peer group companies may not be directly comparable to those of our NEOs with similar or equivalent titles. The Compensation Committee generally considers total direct compensation for an NEO to be competitive if it is near the median of the peer group data.

Peer Group Used for Benchmarking

The peer group used for compensation benchmarking is created based on analysis and recommendations by our independent executive compensation consultant. The peer group is reviewed annually to ensure its composition and characteristics remain consistent with our objectives. As a result of the 2023 review for the 2024 compensation peer group, the Compensation Committee made changes to the peer group by removing two peers, Aspen Technology, Inc. and EVO Payments, Inc., as a result of merger and acquisition activity. The Compensation Committee selected peers based on a combination of business applicability, scale, and impact on peer group size.

(1) | Base salary amounts were effective as of January 1, 2024.

Based on the review and assessment of peer data and competitive market practices for the duties and responsibilities of each position, the Compensation Committee recommended that the Board approve an increase in base salary for all of the NEOs. Mr. Woods’ increase was specifically driven by the expanded duties and responsibilities associated with his promotion to Executive Vice President.

2024 Compensation

Annual Performance Bonuses

Annual performance bonuses are awarded under the terms of our annual performance bonus program and are determined based on the following formula:

Base Salary | X | NEO Target Bonus Percentage | X ( | Company Performance Percentage Achieved | + | People & Culture Percentage Achieved | ) X | NEO Individual Performance Percentage Achieved | = | Total Bonus Earned

NEO Target Bonus Percentage

The Compensation Committee provides competitive performance-based bonus opportunities for the NEOs based on the achievement of annual goals. After considering the competitive compensation information provided by our executive compensation consultant, the 2024 and 2023 target bonus percentages for each NEO were as follows:

NEO | 2024 Target Bonus % |  | 2023 Target Bonus %
Brian Shepherd | 150% |  | 150%
Hai Tran | 100% |  | 75%
Elizabeth Bauer | 75% |  | 75%
Rasmani Bhattacharya | 75% |  | 75%
Michael Woods | 75% |  | 70%

All NEO target bonus percentages were maintained, except for the increase to Mr. Tran’s target bonus from 75% to 100% for 2024 and Mr. Woods’ target bonus from 70% to 75%, which were based on the Compensation Committee’s review and assessment of peer data, competitive market practices, individual performance, and the expansion of their respective responsibilities.

2024 Compensation

Company Performance Percentage

The Company performance percentage is based on our performance against two predetermined financial performance goals: GAAP revenue (“Revenue”) less transaction fees and non-GAAP adjusted operating margin percentage (as defined below). If we achieve the target levels of performance for both measures, the Company performance percentage achieved will be 100%. We must achieve the minimum threshold performance for both measures for the Company performance percentage to exceed zero. If we exceed target levels, the Company performance percentage may reach a maximum of 200%. The predetermined targets for 2024 performance bonuses were established by the Compensation Committee in January 2024. The following table shows our financial results with respect to the 2024 targets:

|  | 2024 Minimum Threshold (30% Payout) |  | 2024 Target (100% Payout) |  | 2024 Maximum (200% Payout) |  | 2024 Results
Revenue less Transaction Fees (in millions) |  | $ | 1,093.0 |  | $ | 1,137.0 |  | $ | 1,177.0 |  | $ | 1,099.4
Non-GAAP adjusted operating margin percentage(1) |  |  | 17.0% |  |  | 17.25% |  |  | 18.15% |  |  | 18.15%

(1) | Non-GAAP adjusted operating margin percentage is calculated by dividing Non-GAAP operating income as a percentage of Revenue less transaction fees. Non-GAAP operating income is defined as our GAAP operating income with the following items added back, as applicable: (a) stock-based compensation; (b) restructuring and reorganization charges; (c) executive transition costs; and (d) acquisition-related expenses (e.g., amortization of acquired intangible assets, earn-out compensation, and transaction-related costs).

The Company’s performance percentage achieved for 2024 based on the results in the above table was calculated at 60.3% and was certified by the Compensation Committee in February 2025. The predetermined targets were established by the Compensation Committee in January 2024. The amount is determined by linear extrapolation between the intersection of established weighted percentages based on Revenue less transaction fees on the x-axis and non-GAAP adjusted operating margin percentage on the y-axis.

Michael Woods’ Customer Experience (CX) and North America Communications, Median & Technology (NA CMT) Performance

Mr. Woods’ bonus is based on the following predefined financial performance metrics of Customer Experience (CX) and North America Communication, Media, and Technology (NA CMT): (i) NA CMT Recognized Revenue (20% weighting); (ii) NA CMT Sales Bookings (15% weighting); (iii) NA CMT Direct Margin (15% weighting); (iv) CX Recognized Revenue (20% weighting); (v) CX Sales Bookings (15% weighting); (iii) CX Direct Margin (15% weighting). Based on actual performance delivered in 2024 against these measures and the outcome of the weighted measure calculation, Mr. Wood received a payout of 96.5%, exclusive of People & Culture modifier.

People & Culture Modifier Percentage

Our annual performance bonus program has included a People & Culture Modifier since 2022. The Board considered the People & Culture Modifier and determined that the 2024 annual performance bonuses did not merit a positive or a negative modification.

NEO Individual Performance Percentage

The final component of the annual performance bonus program is an evaluation of each NEO’s individual performance achievement expressed as a percentage, not to exceed 100%. This evaluation is based on the achievement of certain common and unique objectives described below. These non-financial objectives are important to our success and are designed to enhance shareholder value over the long term.

Common Objectives

Each NEO has multiple common objectives associated with the stewardship of his or her areas of responsibility. The specific objectives vary by NEO but typically include achieving both near- and long-term business objectives and meeting budget expectations.

Unique Objectives

The following are examples of categories of individual unique objectives based on area of responsibility:

■ | Deliver on key development initiatives. The Company has a technology product roadmap that requires significant software development investments aimed at achieving specified feature and functional milestones, and overall, at modernizing our platforms and processes to enhance our market competitiveness.
■ | Maintain and expand customer relationships. It is critical to ensure the relationships with our key customers remain strong and expand to ensure contract renewals result in more profitable revenue growth.
■ | Contribute to growth initiatives. Implementation of our long-term strategic growth plan is a fundamental objective, including the successful completion and integration of our merger, acquisition, and partnership strategies.
■ | Increase cost efficiency. Our NEOs are expected to identify and implement potential cost savings and process efficiencies in identified areas of the Company.
■ | Employee development. Succession planning and development of key leaders and employees is an important organization-wide objective, including transitioning identified tasks and functions to new leaders, where applicable.

The Compensation Committee met in February 2025 to consider the 2024 performance of each NEO as compared to his or her respective performance goals. Mr. Shepherd summarized the 2024 performance of the other NEOs and presented information to the Compensation Committee for review. In addition, the Board met in February 2025 to review the 2024 performance of Mr. Shepherd. After evaluating each NEO’s performance, the Compensation Committee assigned each NEO, including Mr. Shepherd, an individual performance percentage of 100% for 2024.

Final Bonus Calculation

The following table provides each NEO’s earned 2024 annual performance bonus calculation:

NEO |  | Base Salary |  |  | NEO Target Bonus Percentage |  | Company Performance Percentage Achieved |  | People & Culture Modifier Percentage Achieved |  | x |  | NEO Performance Percentage Achieved |  | = |  | 2024 Total Bonus Earned

2024 Compensation

Long-Term Incentive Program

We use our LTI program to provide variable pay compensation in the form of equity that rewards executives when we achieve long-term results that align with shareholders’ interests.

Under our LTI program, we generally grant our NEOs a combination of performance and time-based restricted stock awards (with such performance LTI awards eligible to vest and pay out at up to 200% of the target number of shares), which are administered under our Amended and Restated 2005 Stock Incentive Plan. Each NEO is awarded an aggregate LTI value based on a review of market data and recommendations from our Compensation Committee’s independent executive compensation consultant. For 2024, we added a fourth metric to our mix of awards to emphasize Organic Revenue Growth (defined below) while providing an appropriate balance of performance and time-based compensation to support our long-term strategy. We believe this mix motivates outstanding performance and encourages retention.

2024 LTI AWARD MIX

Award Type |  | Allocation Percentage |  | Alignment to Shareholder Interests
Performance-Based Restricted Stock |  |  |  | Vesting depends on our performance over a two-year to three-year period against specified predetermined performance measures: ■ Non-GAAP EPS (Two-Year) ■ Total Revenue (Two-Year) ■ Average Annual YoY Organic Revenue Growth % (Two-Year) ■ Three-Year Relative TSR
Time-Based Restricted Stock |  |  |  | Provides strong retention incentive over a three-year vesting period and furthers shareholder alignment; value realized for the award depends on our stock price when the award vests

LTI Grant Award Timing

Our Compensation Committee approves LTI awards for our NEOs during scheduled meetings of the Compensation Committee or the Board and LTI awards are made in accordance with the terms of our Amended and Restated 2005 Stock Incentive Plan. The timing of our annual LTI planning and equity grant process is in the first quarter of the year and we generally grant awards to our NEOs and other executives on the tenth of the month following approval. Similarly, during the year, on the same date each month, we may approve grants to certain new hires as part of their hiring total rewards package or grant to certain employees for key retention purposes or part of a special recognition program.

Our restricted stock award agreements provide for the accrual of cash dividends for unvested shares. Accrued dividends are only paid when (and to the extent that) shares vest and are forfeited if the underlying shares are not earned.

See the Executive Compensation Tables – 2024 Grants of Plan-Based Awards for additional information on the 2024 grants.

2024 Performance-Based LTI Award

The 2024 performance-based awards were based on Total Revenue, Average Annual YoY Organic Revenue Growth, Non-GAAP EPS, and TSR relative to the Russell 2000 Index. The portion of the award measured against Total Revenue, Average Annual YoY Organic Revenue Growth, and non-GAAP EPS has an opportunity to vest at the end of a performance period ending December 31, 2025, and the portion based on rTSR has an opportunity to vest at the end of a performance period ending December 31, 2026.

The Compensation Committee selected the measures described below, their associated weightings, and performance period length to focus executives on financial metrics key to our strategic objectives and on driving returns for our shareholders, while balancing long-term goal setting with maintaining a strong line of sight toward achievement on multi-year financial goals.

Performance Measures | Weighting | Definition
Non-GAAP EPS (Two-Year) |  | Calculated by dividing non-GAAP net income by the weighted average of fully-diluted shares outstanding for the period. Non-GAAP net income is defined as pre-tax income calculated in accordance with GAAP, adding back the following items, as applicable: (a) restructuring and reorganization charges; (b) executive transition costs; (c) acquisition-related expenses (e.g. amortization of acquired intangible assets, earn-out compensation and transaction-related costs); (d) stock-based compensation; (e) gain (loss) on acquisitions or dispositions; and (f) gain (loss) on the debt extinguishment/conversion; less income tax expense, determined by applying a non-GAAP effective income tax rate.
Total Revenue (Two-Year) |  | Revenue as reported under GAAP.
Average Annual YoY Organic Revenue Growth (Two-Year) |  | Average Annual Year-over-Year Organic Revenue Growth Percent. Organic Revenue Growth is calculated as the percentage increase in total revenue excluding revenue from acquired companies for a period of 12 months following the date of the acquisition. Calculation of the Organic Revenue Growth will be certified to the Compensation Committee.
Three-Year Relative TSR |  | Percentile ranking against Russell 2000 Index over a three-year period.

For the non-GAAP EPS, Total Revenue, and Average Annual YoY Organic Revenue Growth performance measures, we have established minimum, target, and maximum measures, for which our NEOs may earn from zero to 200% based on the level of achievement over the two-year performance period. For the relative TSR performance measure, we have established minimum, target, and maximum measures, for which our NEOs may earn from 0% to 200% based on the level of achievement over the three-year performance period. The payout is capped at 100% if the absolute TSR is negative.

Due to the competitively sensitive nature of our performance goals, we do not publicly disclose specific financial metric targets. However, the Compensation Committee carefully establishes the financial metric targets and each goal is set at a rigorous growth level and is closely aligned with our forward-looking business strategy.

2024 Time-Based LTI Award

Our time-based restricted stock awards are designed to significantly strengthen the retention value of our LTI program by providing a full value component to balance our performance-based awards. The time-based restricted stock awards generally vest ratably over a three-year period, beginning on the first anniversary of the grant date, subject to continued employment with the Company.

CEO Performance-Based Equity Award

In late 2024, recognizing the ambitious nature of our long-term business strategy and the need for a strong performance incentive aligned with goals and a time frame that exceed those of typical annual equity awards under our LTI program, our Board approved a performance-based equity award for our CEO (“CEO Performance Award”). The CEO Performance Award is intended to provide an enhanced link between our CEO’s long-term incentives and the successful execution of our bold, multi-year strategic goals, which we believe, if effectively executed, can drive stock price performance and significant long-term shareholder value.

The Board only considers awards outside our annual equity programs in limited scenarios, where extraordinary strategic, competitive, or individual factors justify additional performance incentives. In this case, the Board determined that a long-term, stock-price growth-based award was appropriate based on the following reasons:

■ | CSG is undergoing a five-year strategic transformation focused on revenue growth, profitability, cash flow expansion, and revenue diversification. The success of this strategy will be directly measured by its impact on our shareholders.

38 |  | CSG SYSTEMS INTERNATIONAL, INC. 2025 PROXY STATEMENT |

Table of Contents

Compensation Discussion and Analysis

Clawback Policy

■ | The Board believes that the CEO’s incentives should be closely tied to long-term shareholder value. The CEO Performance Award strengths that alignment by linking compensation to stock performance beyond the scope of typical annual equity awards, both in terms of timeframe and performance rigor.
■ | The stock price metric ensures that a portion of our CEO’s compensation is directly tied to the impact of our strategic plan on shareholder value. This structure also provides flexibility in an uncertain market environment, where setting precise long-term operational goals can be challenging.

The CEO Performance Award had a grant date value of $4.0 million based on the closing price of CSG common stock on the date of grant, representing a 100% achievement, with a right to earn additional shares representing up to 200% achievement. The CEO Performance Award vests contingent upon the achievement of predetermined stock price thresholds over a five-year period, all of which are set above our all-time high stock price. Achievement of the CEO Performance Award is also subject to time-based service vesting conditions of between three and five years. The stock price thresholds and service vesting period for each tranche are outlined in the table below. Significant, sustained stock price growth is required for any shares to vest, requiring a 40% increase from the grant date stock price to be achieved to vest at target levels, reinforcing the CEO Performance Award’s emphasis on long-term, sustained stock price growth and strong alignment with shareholder interests.

Tranche | Stock Price Threshold | Cumulative Award Shares Eligible to Vest (as a % of the number of Target Shares) |  | Service Vesting Dates |  | % Growth from Grant Price $53.71
1 | $70 | 50% |  | December 10, 2027 |  | 30%
2 | $75 | 100% |  | December 10, 2028 |  | 40%
3 | $80 | 150% |  | December 10, 2029 |  | 49%
4 | $85 | 200% |  | December 10, 2029 |  | 58%

The stock price threshold will be deemed achieved as of the date on which the 90 calendar day trailing average per closing stock price equals or exceeds that stock price threshold. Subject to continued employment with CSG per the terms of the CEO Performance Award, each tranche of the CEO Performance Award will vest on the later of: (i) the achievement of the applicable stock price threshold; or (ii) the applicable service vesting date. Any portion of the CEO Performance Award that does not vest by December 10, 2029 will be forfeited. Under the terms of the CEO Performance Award, the CEO Performance Award may vest in full or in part, to the extent that stock price thresholds have been met, upon an involuntary termination of employment (including a constructive termination) following a change in control.

Clawback Policy

We adopted an updated clawback policy in November 2023 to address the recovery of erroneously awarded incentive-based compensation in compliance with SEC and Nasdaq rules. Our clawback policy authorizes the Company to reduce, cancel, or require the recovery of all or a portion of a current or former executive officer’s annual bonus or LTI compensation award, including the recoupment of cash, time-based stock compensation, and performance-based stock compensation, in the context of a material restatement of the financial statements of the Company due to material noncompliance with any financial reporting requirement under applicable securities laws. In connection with our executive severance policy, the Company is also authorized to reduce or cancel, or require the recovery of all or a portion of an NEO’s annual bonus or LTI award paid as severance under such policy.

Anti-Hedging and Anti-Pledging Policy

As part of our Insider Trading Policy, all employees and directors (and their designees) are prohibited from engaging in short sales of our securities and engaging in transactions that are designed to hedge, pledge, or offset any decrease in the market value of our stock, including certain forms of hedging, pledging and monetization transactions, such as zero-cost collars, prepaid variable forward sale contracts, equity swaps, and exchange funds.

Other Considerations

Other Considerations

Other Benefits

The Compensation Committee does not believe that perquisites and other benefits should play a major role in the overall compensation of our NEOs. We offer our NEOs substantially the same benefits as our other employees, including health, dental, vision coverage, life and disability insurance, and the opportunity to defer a portion of their annual base salary and annual performance bonus through a 401(k) plan that is generally available to our U.S.-based population. The 401(k) plan includes Company matching contributions.

In 2021, the Board decided to freeze the non-qualified deferred compensation program discussed in 2024 Non-Qualified Deferred Compensation. Under this plan, in prior active years, a matching contribution was made equal to 25% of NEOs’ contributions, up to a maximum of $6,250 per NEO per year. Due to the limited historical employee participation rate in the non-qualified deferred compensation program, the Board froze the plan effective January 1, 2022, and as such prohibited any future contributions to the program.

Our NEOs participate in an Executive Severance Plan that provides benefits in the event of an involuntary separation from service. See Severance and Change in Control Benefits for details.

Tax Deductibility of Executive Compensation

Section 162(m) of the Internal Revenue Code and regulations promulgated thereunder generally limit the amount of compensation we can deduct in any one fiscal year for compensation paid to our CEO, CFO, and certain other covered employees to $1 million. The changes in U.S. tax law expanded the definition of “covered employees” to include any person who served as chief executive officer or chief financial officer at any time during a taxable year, as well as any person who was ever identified as a covered employee in 2017 or any subsequent year. While the Compensation Committee considers the deductibility of compensation as one factor in determining executive compensation, it retains the flexibility to grant discretionary awards and make payments that it determines to be consistent with the goals of our executive compensation program even if the amounts are not deductible by the Company for tax purposes.

Accounting Considerations

Financial Accounting Standards Board ASC Topic 718, Compensation—Stock Compensation (“ASC Topic 718”), requires us to recognize an expense for the fair value of equity-based compensation awards over the expected service period. Grants of stock awards under our equity incentive award plans are accounted for under ASC Topic 718. We will consider the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs. As accounting standards change, we may revise certain programs to appropriately align the accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Proposal 2 — Advisory Vote to Approve the Compensation of Our Named Executive Officers

We are asking our shareholders to vote to approve, on an advisory (nonbinding) basis, the compensation of our NEOs as disclosed in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our shareholders the opportunity to express their views on the compensation of our NEOs. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the philosophy, policies, and practices described in this proxy statement.

As described in Compensation Discussion and Analysis, our executive compensation program is designed to attract and retain qualified executives, recognize and reward individual performance, and align executive pay with shareholder return over both the short and long term. Under our executive compensation program, our NEOs are rewarded for achieving specific annual and long-term strategic, financial, and operational goals, and for increasing shareholder value.

The say-on-pay vote is advisory, and therefore not binding on the Company, the Compensation Committee, or our Board. The approval or disapproval of this proposal by shareholders will not require the Board or the Compensation Committee to take any action regarding our executive compensation practices. However, the Board and Compensation Committee value the opinions of our shareholders and will consider the outcome of the vote when considering future decisions on the compensation of our NEOs.

2024 Non-Qualified Deferred Compensation

The following table contains information about contributions, earnings, withdrawals, and account balances for our NEOs under the Company’s non-qualified Wealth Accumulation Plan. In 2021, due to the limited historical employee participation rate, the Board decided to freeze the Plan effective January 1, 2022, and prohibited any further contributions to the Wealth Accumulation Plan.

The Wealth Accumulation Plan was an elective, unfunded deferred compensation plan intended to build net worth through the deferral of cash compensation on a before-tax basis. Participation in the Wealth Accumulation Plan was limited to Vice Presidents and above, including the NEOs. Each participant was required to elect by December of the preceding year to defer: (1) up to 25% of the participant’s base salary; and/or (2) up to 100% of the participant’s cash bonus. All eligible employees could elect to defer up to $700,000 in the aggregate for any one year. A matching contribution was made equal to 25% of the deferral, up to a maximum of $6,250 per participant for any one plan year. The Non-Qualified Deferred Compensation Table below shows the aggregate amount each NEO elected to defer and the amount that the Company contributed to the Wealth Accumulation Plan.

Payment may be made as a lump sum or in monthly installments for up to 180 months, depending on whether the participant elects to receive payment as an in-service distribution or upon termination of employment, and the payment options offered at the time of the participant’s deferral election. Generally, Wealth Accumulation Plan deferral account benefit payments will not begin earlier than the elected commencement date. If a participant dies, the participant’s deferred compensation benefit will be paid to his or her beneficiaries or estate in a lump sum. Participants may request an early withdrawal in the event of an unforeseen emergency, which request is subject to approval. For all participants, distributions triggered by termination of employment are automatically delayed six months. The Company has reserved the right to terminate the Wealth Accumulation Plan and distribute all vested amounts credited to participant accounts upon a change in control.

The participant may select from a wide mix of investment crediting funds that best suit their goals, time horizon, and risk tolerance. The investment options available and their performance, as well as planning tools to assist the participant in selecting an appropriate mix, are available online with the record keeper. The participant may change investment crediting elections or request investment exchanges between options whether online or through phone services with the record keeper. Investment crediting options are used to measure the notional gains and losses that will be credited to the participant’s account over time. While no actual investment is made in the investment crediting options selected, the participant’s account is subject to the same market investment risk as the actual investment in such investment crediting options.

Participants were fully vested immediately in their own salary deferrals and vested 100% in Company matching contributions after three years of service. All NEOs who participated in the plan were fully vested in their Wealth Accumulation Plan account balances at the time the Wealth Accumulation Plan was frozen.

Severance and Change in Control Benefits

Executive Severance Plan

The Compensation Committee regularly reviews and benchmarks severance benefits to ensure they are consistent with market best practices as well as consistent among executives of similar seniority and responsibility across the Company. The Compensation Committee believes that maintaining a competitive level of separation benefits is appropriate as part of an overall compensation program designed to attract, retain, and motivate the highest-quality management team.

The Executive Severance Plan standardizes the benefits to be provided to our executives in the event of termination by CSG for any reason other than cause, death, or disability, or by the executive for good reason (each, a “Qualifying Termination”), as such terms are defined under the Executive Severance Plan.

Each of our executive officers participate in the Executive Severance Plan with each of Mr. Shepherd and Ms. Bauer entering into participation agreements that differ from the standard form participation agreement in order to reflect benefits previously contained in their respective 2021 employment agreements (which were terminated in connection with the adoption of the Executive Severance Plan) and other benefits as described below.

In the event of a Qualifying Termination that does not occur within the first 18 months following a Change in Control of CSG, executives participating in the Executive Severance Plan would receive the following separation benefits:

■ | a severance payment consisting of an amount equal to 100% of the executive’s annual base salary and 100% of the target bonus, paid over a 12-month period; provided, with the exception of Mr. Shepherd, whose payment is based on 200% of his base salary and 100% of the target bonus pursuant to his participation agreement;
■ | a lump sum amount equal to the COBRA continuation coverage premiums that would be payable by the executive for the first 18 months of the COBRA continuation period;
■ | if the termination occurs on or after June 1 of the applicable calendar year, a lump sum payment consisting of the executive’s annual bonus, pro-rated for the number of days the executive was employed during the calendar year and based on the actual performance of the company for the year in which the executive’s termination date occurs; and
■ | a pro-rated portion of the unvested time-based restricted stock award and a pro-rated portion of the unvested performance-based restricted stock awards with the vesting amount of both based on the number of months employed during the vesting cycle and with the performance-based stock vesting based on the actual performance achieved at the end of the performance period.

Severance and Change in Control Benefits

In the event of a Qualifying Termination within the first 18 months following a change in control of CSG, executives participating in the Executive Severance Plan would receive, subject to any limitations under 280G, the following separation benefits:

■ | a lump sum severance payment consisting of an amount equal to 200% of the executive’s annual base salary and target bonus, with the exception of Mr. Shepherd and Ms. Bauer, who would receive an amount equal to 300% of their annual base salary and target bonus as reflected in their participation agreements;
■ | a cash amount equal to the COBRA continuation coverage premiums that would be payable by the executive for the first 18 months of the COBRA continuation period;
■ | an additional lump sum payment consisting of the executive’s target bonus, pro-rated for the number of days the executive was employed during the calendar year; and
■ | vesting of all unvested time-based and performance-based restricted stock awards, with the vesting amount for the performance-based stock awards determined at target; provided, however, that for any performance-based stock awards on a relative TSR metric, the performance period would be deemed to have ended on the date of the change in control and will be valued on that date.

Payments to executives under the Executive Severance Plan are contingent on, among other things, the executive entering into and complying with a broad-based release of CSG.

Potential Payments Upon Termination of Employment Under the Executive Severance Plan

Potential Payments Upon Termination of Employment Under the Executive Severance Plan

The following describes the additional amount of compensation that would be paid to each of our NEOs under the Executive Severance Plan in the event of a termination of the NEO’s employment under various scenarios. The amounts shown are estimates of the amounts that would be paid to each NEO assuming a termination was effective as of December 31, 2024. We used $51.11 per share, the closing price of our common stock as of December 31, 2024 (the last trading day of our 2024 fiscal year), in determining the potential value of accelerated vesting of restricted stock awards. The actual amounts to be paid can only be determined at the time of an NEO’s separation from us.

Termination for Death or Disability

Assuming termination of employment on December 31, 2024, if our NEO’s employment is terminated by reason of disability, he or she would receive continued coverage under the group insurance benefits until the first to occur of the cessation of such disability or the attainment of age 65. The total disability value of premiums as of December 31, 2024, for the group insurance benefits were $252,726 for Mr. Shepherd (age 57), $315,907 for Mr. Tran (age 55), $67,139 for Ms. Bauer (age 62), $96,142 for Ms. Bhattacharya (age 56), and $781,803 for Mr. Woods (age 40).

In addition, Mr. Shepherd and Ms. Bauer would receive accrued benefits, any other amounts or benefits earned, accrued, or owed but not paid as of the employment termination date, and his or her pro-rated bonus at target performance for 2024 in accordance with the terms of his or her respective Executive Severance Plan participation agreements.

All outstanding unvested time-based equity awards will vest in full upon the NEO’s death. The values of the unvested time-based awards for each of our NEOs as of December 31, 2024, were $5,161,088 for Mr. Shepherd, $1,783,177 for Mr. Tran, $1,084,197 for Ms. Bauer, $834,269 for Ms. Bhattacharya, and $586,794 for Mr. Woods all based on values on the last trading day of the year, December 31, 2024. For more information, see Outstanding Equity Awards at Fiscal Year-End.

Termination for Cause

Assuming termination of employment on December 31, 2024, by the Company for cause, the NEO would receive accrued benefits through the termination date and any other amounts or benefits earned, accrued, or owed to but not paid as of the employment termination date.

Cause

Under the Executive Severance Plan, “Cause” means that one or more of the following have occurred: (i) the executive’s willful and deliberate failure to substantially perform his or her executive and management duties hereunder to the detriment of the Company for reasons other than employee’s sickness, injury, or disability; (ii) the executive’s willful and deliberate misconduct, which is a material violation of the Company’s written policies and/or results in substantial injury or damage (whether reputational, financial, or otherwise) to the Company; (iii) the executive’s conviction of, or plea of guilty or nolo contendere to, a felony; (iv) the executive’s breach of any restrictive covenant agreement with the Company, including but not limited to, confidentiality noncompete, nonsolicitation and/or nondisclosure covenants; and (v) the executive’s certification of materially inaccurate financial or other information pertaining to the Company with actual knowledge of such inaccuracies on the executive’s part. In no event will the results of operations of the Company or exercise of the executive’s business judgment made in good faith constitute an independent basis for terminating the executive’s employment for Cause.

Change in Control

Under the Executive Severance Plan, a “Change in Control” of the Company generally includes (i) the date any one person, or more than one person acting as a group, acquires ownership of stock of the Company that, together with stock held by such person or group constitutes more than 50% of the total voting power of the stock of the Company. However, if any one person, or more than one person acting as a group, is considered to own more than 50% of the total fair market value or total voting power of the stock of the Company, the acquisition of additional stock by the same person or persons is not considered causing a change in the ownership of the Company or to cause a change in the effective control of the Company; (ii) the date any one person, or more than one person acting as a group, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) ownership of stock of the Company possessing 50% or more of the total voting power of the stock of the Company; (iii) the date that any one person, or more than one person acting as a group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all the assets of the Company immediately before such acquisition or acquisitions; or (iv) the date a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election. A more detailed definition of Change in Control is included in the Executive Severance Plan.

Good Reason

Under the Executive Severance Plan, “Good Reason” exists if, without the executive’s consent, any of the following applies: (i) a material diminution in the executive’s duties, responsibilities, or authority; or (ii) a material reduction in base salary (other than a reduction effected on behalf of the Company as part of a general cost-saving strategy that affects similarly situated employees of the Company); or (iii) following a Change in Control, the assignment to the executive of duties significantly inconsistent with, or different from, the executive’s duties and responsibilities existing at the time of the Change in Control.

The executive may terminate his or her employment for “Good Reason” by giving the Company 30 days’ notice of any event or condition that would constitute a basis for “Good Reason” within 90 days of such event or condition first arising. Upon receipt of such notice, the Company will have 30 days to cure, and if not cured within such period, the executive’s termination will be effective upon expiration of the 30-day cure period.

CEO Pay Ratio

Pursuant to Item 402(u) of SEC Regulation S-K, we are required to annually disclose the ratio of the annual total compensation of our CEO to that of our median employee.

We believe the pay ratio disclosed below is a reasonable estimate calculated in a manner consistent with applicable SEC rules. Because there has been significant changes within our employee population, we recalculated the median employee for 2024. To identify the median employee in 2024 and to determine the annual total compensation, as defined below, of our median employee and our CEO, we took the following steps:

■ | We selected December 31, 2024, as the date on which we would identify our median employee because it enabled us to make such identification in an efficient and reasonable manner;
■ | We identified our median employee, after accumulating annual base pay, bonus earned, and equity granted (“Annual Total Compensation”) for our entire global employee workforce, excluding our CEO, based on the local currency of the countries in which they were employed for the fiscal year that ended on December 31, 2024;
■ | Each employee’s Annual Total Compensation was then converted to U.S. Dollars using average foreign currency rates prevailing during the year, and arrayed high to low to identify our median employee; and
■ | We calculated total compensation for the median employee in a similar manner that we calculated compensation for our NEOs for our 2024 Summary Compensation Table (“Total Compensation”), resulting in Total Compensation for our median employee of $73,476 for the year ended December 31, 2024.

Our CEO’s Total Compensation for 2024 was $11,394,373, as reported in the Executive Compensation Tables - 2024 Summary Compensation Table, and was approximately 155 times the Total Compensation of the median employee.

Relationship Between Pay and Performance

We believe the compensation actually paid in each of the years reported above and over the five-year cumulative period are reflective of the Compensation Committee’s emphasis on “pay-for-performance” as it fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our annual performance bonus and our LTI program, including our Revenue.

Revenue continues to be our most important financial metric due to the following:

■ | Revenue growth is a critical part of our long-term strategic objectives.
■ | Our CEO and executive leadership team have set a long-term revenue target of $1.5 billion.
■ | Revenue or a related metric is included in both short-term and long-term incentive programs.
■ | For the following relationship depictions, the compensation actually paid for the current CEO and former CEO have been aggregated.

Proposal 3 — Ratification of the Appointment of KPMG LLP as

Our Independent Registered Public Accounting Firm for Fiscal 2025

KPMG LLP has served as our independent registered public accounting firm since 2002 and has been appointed by the Audit Committee to serve in such capacity for 2025. The Company expects that representatives of KPMG LLP will attend the Annual Meeting. Such representatives will have the opportunity to make a statement if they wish, and they will be available to respond to appropriate questions.

The following table sets forth the amounts paid to KPMG in three categories.

“Audit Fees” are the aggregate fees billed by KPMG LLP for 2024 and 2023 for professional services rendered for audits of our annual consolidated financial statements and reviews of financial statements included in the Company’s Quarterly Reports on Form 10-Q/Form 10-K, as well as for services that are normally provided by KPMG LLP in connection with statutory and regulatory filings or engagements for such periods, such as the attestation on the effectiveness of the Company’s internal control over financial reporting.

“Audit-Related Fees” are the aggregate fees billed by KPMG LLP in 2024 and 2023 for assurance and related services that are reasonably related to the performance of the audits or reviews of the Company’s financial statements and are not reported under “Audit Fees.”

“Tax Fees” are the aggregate fees billed by KPMG LLP in 2024 and 2023 for federal, state, and foreign tax compliance, tax advice, and tax planning services.

|  |  | 2024 |  |  | 2023
Audit Fees |  | $ | 2,603,200 |  | $ | 2,471,170
Audit-Related Fees |  |  | 726,800 |  |  | 723,740
Tax Fees |  |  | 14,600 |  |  | 16,400
TOTAL FEES |  | $ | 3,344,600 |  | $ | 3,211,310

Other than as reported above, no other fees were billed by KPMG LLP for 2024 or 2023. All of the services listed above were pre-approved by the Audit Committee under the procedures described below.

Proposal 3 — Ratification of the Appointment of KPMG LLP as Our Independent Registered Public Accounting Firm for Fiscal 2025

Pre-approval Policies and Procedures

Pre-approval Policies and Procedures

The Audit Committee charter requires the Audit Committee to approve, before services are performed, all audit and permissible non-audit-related services to be provided to the Company by the Company’s independent registered public accounting firm. The Audit Committee has delegated to its Chair the authority to perform the Audit Committee’s responsibilities with respect to such approvals. The Audit Committee Chair is required to report to the Audit Committee at its next meeting on the manner in which such delegated performance was carried out. Each year since 2002, the engagement of KPMG LLP to provide services to the Company has been approved in advance either by the Audit Committee or by its Chair pursuant to this delegated authority.

The Audit Committee annually evaluates the performance of the independent registered public accounting firm and determines whether to engage the current independent auditors or consider other independent audit firms. Factors considered by the Audit Committee in deciding whether to retain the current independent auditors include:

■ | quality of service and sufficiency of resources;
■ | communication and interaction; and
■ | independence, objectivity, and professional skepticism.

Based on this evaluation, the Audit Committee and the Board believe that retaining KPMG LLP to serve as our independent registered public accounting firm for the year ending December 31, 2025, is in the best interests of the Company and its shareholders.

Although the Audit Committee is directly responsible for the appointment of the Company’s independent registered public accounting firm, the Board is requesting that shareholders ratify such appointment as a matter of good corporate governance. If shareholders do not ratify such appointment, the Audit Committee nevertheless may determine that it is in the best interests of the Company and its shareholders to retain KPMG LLP for the year ending December 31, 2025. Regardless of the vote on this proposal, the Audit Committee at any time during the year may appoint a different independent registered public accounting firm for the year ending December 31, 2025, if the Audit Committee determines that such a change would be in the best interests of the Company and its shareholders.

| THE BOARD RECOMMENDS THAT SHAREHOLDERS VOTE FOR RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL 2025.

Report of the Audit Committee

The primary purposes of the Audit Committee, as set forth in its charter, are to oversee the Company’s accounting and financial reporting processes and the audits of the Company’s consolidated financial statements and to provide oversight of our risk and compliance management programs. The Audit Committee has implemented procedures to help it execute these responsibilities. During 2024 and through the completion of the audit of the Company’s consolidated financial statements for that year, those procedures included regular meetings with management and with appropriate representatives of the Company’s independent registered public accounting firm.

We reviewed and discussed both with management and with the Company’s independent registered public accounting firm, KPMG LLP, the Company’s audited consolidated financial statements for the year ended December 31, 2024.

We also discussed with KPMG LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and the SEC.

We received the written disclosures and the letter from KPMG LLP required by the applicable requirements of the PCAOB regarding KPMG LLP’s communications with the Audit Committee concerning independence, and have discussed with KPMG LLP its independence.

Based upon these reviews and discussions, we recommended to the Board that the audited consolidated financial statements of the Company as of and for the year ended December 31, 2024, be included in the Company’s Annual Report on Form 10-K for such year for filing with the SEC.

Related Party Transactions

The Audit Committee of the Board is responsible for reviewing and approving all related party transactions that must be reported under applicable SEC rules. Related party transactions are those (a) involving the Company, (b) in which one of our directors, nominees for director, executive officers, or greater than five percent shareholders, or their immediate family members, have a direct or indirect material interest, and (c) where the amount involved exceeds $120,000 in any fiscal year.

Various policies and procedures of our Company, including the charter of the Audit Committee and annual questionnaires completed by all of our directors and executive officers, require the directors and executive officers to disclose and otherwise identify to the Company the transactions or relationships that could be viewed as constituting potential or actual conflicts of interest or otherwise require disclosure under applicable SEC rules as “related person transactions” between our Company or its subsidiaries and related persons. In determining whether to approve or reject any such transaction, the Audit Committee would consider all relevant facts and circumstances it deems necessary to make a decision, including the nature, type, frequency, and dollar amount(s) involved in the transaction, and the risks, costs, and benefits to the Company.

There were no related party transactions during 2024 and there are not any currently proposed transactions, in which the Company and any related person were or are participants, that would be required to be disclosed pursuant to Item 404 of SEC Regulation S-K.

Questions and Answers about the 2025 Annual Meeting and Voting

How to Participate in the Annual Meeting

What items of business will be voted on at the Annual Meeting and how does the Board suggest I vote?

Three proposals are scheduled to be voted on at the Annual Meeting:

Proposal |  |  |  | Board Recommendation
Proposal 1 |  | To elect our three Class I Directors |  | FOR each nominee
Proposal 2 |  | To approve, on an advisory basis, the compensation of our named executive officers |  | FOR
Proposal 3 |  | To ratify the appointment of KPMG LLP as our independent registered public accounting firm for fiscal 2025 |  | FOR

We also will transact any other business that properly comes before the Annual Meeting.

What shares can I vote?

You are entitled to one vote for each share of our common stock that you owned as of the close of business on March 20, 2025, the “record date” for the Annual Meeting. You can also vote all shares for which you hold a valid proxy. At the close of business on the record date, there were 28,773,311 shares of our common stock outstanding.

May I attend the Annual Meeting?

There will not be a physical location for the meeting. You may attend the virtual Annual Meeting only if you were a shareholder of the Company as of the record date or you hold a valid proxy for the Annual Meeting. You will need the 16-digit control number included in your Notice of Internet Availability, on your proxy card, or on the instructions that accompany your proxy materials.

May I vote my shares at the Annual Meeting?

If you are a shareholder of record—meaning you hold our common stock in your name with our transfer agent (Computershare Trust Company, N.A.)—you may vote your shares online at the Annual Meeting. If you are a beneficial owner—meaning that a broker, bank, trustee, or other nominee holds your common stock in “street name”—you can vote online during the Annual Meeting only if you obtain a valid proxy from the record holder giving you the right to vote the shares. Even if you plan to attend the Annual Meeting, we recommend that you submit your proxy or voting instructions as soon as possible so that your vote will be counted if you later decide not to attend the Annual Meeting.

May I vote my shares without attending the Annual Meeting?

You may direct how your shares are voted without attending the Annual Meeting. If you are a shareholder of record, you will receive a Notice of Internet Availability, which explains how to access the proxy materials online, contains a listing of matters to be considered at the Annual Meeting, and describes how shares can be voted by telephone, online, or by completing and returning a proxy card. If you hold shares beneficially in “street name,” your broker, bank, trustee, or other nominee should provide you a means to instruct how your shares should be voted.

Questions and Answers about the 2025 Annual Meeting and Voting

How to Participate in the Annual Meeting

What if I am a beneficial owner and do not give voting instructions to my broker?

If you are a beneficial owner of CSG shares, your broker, bank, or other nominee is not permitted to vote on your behalf on Proposal 1 (the election of directors), Proposal 2 (the advisory say-on-pay proposal), or any other matter to be considered at the Annual Meeting except for Proposal 3 (the ratification of the appointment of KPMG LLP as our independent auditor for 2025), unless you provide specific instructions by completing and returning the voting instruction form or following the instructions you receive about voting your shares on the Internet or by telephone. A broker non-vote occurs when a broker, bank, trustee, or other nominee returns a proxy card but does not vote on one or more matters because such broker, bank, trustee, or other nominee does not have the authority to do so without instructions from the beneficial owner. Broker non-votes and discretionary authority are further described below. If you do not provide voting instructions, your shares will not be voted on any proposal except for Proposal 3. For your vote to be counted, you will need to communicate your voting instructions in a timely manner as directed by your broker, bank, or other nominee.

What if I return my proxy card but do not provide voting instructions?

If you are a shareholder of record and you return your signed proxy card without giving specific voting instructions, your shares will be voted as recommended by the Board.

May I change or revoke my vote?

If you are a shareholder of record, there are three ways to change or revoke your vote before the conclusion of voting at the Annual Meeting: (1) deliver a new proxy bearing a later date by mail, telephone, or over the Internet, which automatically revokes your earlier proxy; (2) provide a written notice of revocation to our Secretary at our principal offices listed on the first page of this proxy statement; or (3) vote online during the Annual Meeting. Attending the Annual Meeting without voting will not affect your previously granted proxy.

If you are a beneficial owner, you may change your vote by submitting new voting instructions to your broker, bank, trustee, or other nominee. Alternatively, if you have obtained a valid proxy from your broker, bank, trustee, or other nominee giving you the right to personally vote your shares, you can vote online during the Annual Meeting.

How many shares must be present or represented to conduct business at the Annual Meeting?

We can transact business at the Annual Meeting if a majority of the issued and outstanding shares of common stock entitled to vote are present or represented by proxy. Abstentions are counted for the purpose of determining whether there is a quorum.

“Broker non-votes” will be counted for the purpose of determining whether there is a quorum as long as the bank, broker, or nominee uses its discretionary authority to vote on Proposal 3 (the ratification of the appointment of KPMG LLP as our independent auditor for 2025).

Questions and Answers about the 2025 Annual Meeting and Voting

How to Participate in the Annual Meeting

What is the voting requirement to approve each of the proposals?

Proposal |  |  |  | Vote Required to Pass |  | Effect of Abstentions and Broker Non-votes
Proposal 1, Election of Directors |  |  |  | Each nominee who receives a majority of the votes cast for his or her election (meaning the number of votes cast FOR a director’s election exceeds the number of votes cast AGAINST that director’s election) will be elected as a director. |  | Abstentions will have no effect Broker non-votes will have no effect
Proposal 2, Advisory Say-on-Pay Vote |  |  |  | The Board will consider shareholders to have approved this advisory proposal if it receives the affirmative vote of a majority of the shares present at the meeting or represented by proxy at the meeting and entitled to vote. |  | Abstentions will have the same effect as votes AGAINST Broker non-votes will have no effect
Proposal 3, Ratification of Auditors |  |  |  | The proposal will be approved if it receives the affirmative vote of a majority of the shares present at the meeting or represented by proxy at the meeting and entitled to vote. |  | Abstentions will have the same effect as votes AGAINST Broker non-votes will have no effect

The majority voting standard described above for the election of directors applies in any “uncontested election” of directors (i.e., an election where the number of nominees does not exceed the number of directors to be elected).

If a continuing director seeking re-election does not receive a majority of the votes cast FOR his or her election, that director must submit a resignation to the Board, with a presumption that the resignation will be accepted unless the Board determines there is a compelling reason for the director to remain on the Board. In the case of a contested election, directors will be elected by a plurality vote, meaning that the nominees who receive the greatest number of votes cast FOR their election will be elected.

How are votes counted?

Votes cast will be tabulated by the inspector of elections appointed for the Annual Meeting. If you provide specific instructions on your proxy card, your shares will be voted as you instruct.

What happens if additional matters are presented at the Annual Meeting?

We are not aware of any business to be acted upon at the Annual Meeting other than the three proposals described in this proxy statement. If you grant a proxy, the individuals named as proxy holders, Brian A. Shepherd and Rasmani Bhattacharya, will have the discretion to vote your shares on any additional matters properly presented for a vote at the Annual Meeting.

Who will bear the cost of soliciting votes for the Annual Meeting?

We will pay the entire cost of preparing, assembling, printing, mailing, and distributing these proxy materials, and soliciting votes. Our directors, executives, and regular employees, without additional remuneration, and their appointed agents, may solicit proxies or votes in person, by telephone, or by electronic communication. We will request banks, brokers, and other fiduciaries to forward proxy materials to the owners of stock held in their names and will reimburse their reasonable out-of-pocket expenses incurred in connection with that distribution.

Where can I find the voting results of the Annual Meeting?

We will announce voting results of the Annual Meeting in a Current Report on Form 8-K filed with the SEC no later than four business days after the Annual Meeting.

For shareholder proposals and shareholder nominations submitted outside of the SEC proposal rules, our bylaws require that the Secretary of the Company receive advance written notice in proper form for matters to be brought before an annual shareholders meeting. We must receive notice of such shareholder proposals for the 2026 annual meeting no later than December 2, 2025.

Householding

We have adopted a procedure called “householding.” This practice allows us to deliver only one copy of proxy-related materials, annual reports, and information statements to shareholders who share the same address and last name and who do not participate in e-mail delivery of these materials unless one or more shareholders notify us that he or she would like to receive an individual copy. If you share an address with another shareholder and receive only one set of proxy-related materials and would like to request a separate copy for this year’s Annual Meeting or for future meetings or shareholder communications, please send your written request to CSG Systems International, Inc., 169 Inverness Drive West, Suite 300, Englewood, Colorado 80112, Attn: Investor Relations Department or to john.rea@csgi.com or call us at (303) 200-2000.
