I am pleased to invite you to join our Board of Directors and senior leadership for our 2026 Annual Meeting of Stockholders (Annual Meeting), which will be held on Tuesday, May 12, 2026, at 12:00 p.m. Central Daylight Time. Our Annual Meeting will be a virtual meeting of stockholders, which will be conducted via live audio webcast.

The attached Notice of Annual Meeting of Stockholders and proxy statement will serve as your guide to the business to be conducted at the meeting. We are also mailing a Notice of Internet Availability of Proxy Materials (Notice) to our stockholders. We believe the Notice process allows us to provide our stockholders with the information they desire in a timely manner, while saving costs and reducing the environmental impact of our Annual Meeting. The Notice contains instructions on how to access our 2025 Annual Report (which includes our 2025 Annual Report on Form 10-K), proxy statement and proxy card over the internet, as well as instructions on how to request a paper copy of the materials, if desired.

Your vote is very important to us. We encourage you to sign and return your proxy card and/or vote by telephone or via the internet following the instructions on the Notice as soon as possible so that your shares will be represented and voted at the Annual Meeting. Instructions on how to vote are on page 10 of the proxy statement.

**We urge you to read the accompanying proxy statement carefully and to vote FOR the director nominees proposed by the Board of Directors, FOR proposals 2 and 3 and AGAINST proposal 4, in accordance with the recommendations of the Board of Directors.** 

On behalf of your Board of Directors, thank you for your confidence in TransUnion. We look forward to your continued support.

Submitting Questions During the Annual Meeting

We are committed to ensuring, to the extent possible, that stockholders will be afforded the ability to participate at the virtual meeting similarly to how they would participate at an in-person meeting. As part of the Annual Meeting, we will answer questions following the presentation of each proposal to be voted on at the Annual Meeting, and will hold a live online Q&A session, during which we intend to answer questions submitted before or during the Annual Meeting, as time permits. Questions must be confined to matters properly brought before the Annual Meeting and/or of general Company concern. We reserve the right to edit profanity or other inappropriate language, or to exclude questions that are not pertinent to meeting matters or that are otherwise inappropriate. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition. We kindly ask stockholders not to ask more than two questions in order to allow us to answer questions from as many stockholders as possible. Questions may be submitted during the Annual Meeting through <u>www.virtualshareholdermeeting.com/TRU2026</u>.

Technical Assistance During the Annual Meeting

If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the login page at <u>www.virtualshareholdermeeting.com/TRU2026</u>. Please check in beginning at 11:45 a.m. Central Daylight Time on May 12, 2026, the day of the Annual Meeting, so we may address any technical difficulties before the Annual Meeting.

Executive Compensation Highlights

#### Executive Compensation Philosophy
Our executive compensation program is based on a philosophy that aligns the interests of our executives and stockholders. The following are key objectives of our compensation philosophy:

• Attract, motivate and retain highly experienced executives who are vital to our short- and long-term success, profitability and growth;

• Align the focus of our executives with the interests of our stockholders by rewarding executives for the achievement of strategic goals that successfully drive our strategy, operations and business performance and, thereby enhance stockholder value;

• Differentiate pay and rewards based on criticality of role and actual individual and company financial performance while remaining fair and equitable; and

• Promote thoughtful decision-making while discouraging unnecessary and excessive risk-taking.

#### Strong Stockholder Support
Our most recent Say-on-Pay vote was held at our 2025 Annual Meeting of Stockholders and received 95.14% stockholder support. We believe this strong Say-on-Pay vote outcome demonstrates stockholder support for our executive compensation program.

#### Executive Compensation Payouts are Aligned with our Named Executive Officers' ("NEOs") and the Company's Performance During 2025
• Our NEOs' 2025 annual incentive payouts were 154% of target resulting from above target performance achievement on all three performance measures: Defined Consolidated Adjusted EBITDA, Defined Consolidated Revenue and Defined Adjusted Diluted Earnings per Share.

• Our 2023 PSU (as defined on page 44) performance total weighted payout was 142% of target resulting from above target performance achievement on Cumulative Adjusted EBITDA (30% weighting), Cumulative Revenue (20% weighting), and Relative TSR (as defined on page 44) (50% weighting).

#### Target Compensation Mix is Linked to Company Performance and Aligned with Stockholders' Interests
• 93% of our CEO's 2025 target compensation and 83% of our other NEOs' 2025 target compensation is "at-risk" based on Company and share price performance.

• 80% of our CEO's 2025 target compensation and 65% of our other NEOs' 2025 target compensation is based on long-term incentives aligned with stockholders' interests.

---

Q: Why are we holding a virtual Annual Meeting?

---

| | |
|:---|:---|
| A: | We will continue using the latest technology to provide expanded access, improved communication and cost savings for our stockholders and the Company while providing stockholders the same rights and opportunities to participate as they would have at an in-person meeting. Furthermore, we believe that hosting a virtual meeting is in the best interest of the Company and its stockholders and enables increased stockholder attendance and participation because stockholders can participate from any location around the world.  |

---

---

| | |
|:---|:---|
| Q: | Who is entitled to vote at the Annual Meeting?  |

---

---

| | |
|:---|:---|
| A: | Only stockholders of record at the close of business on March 16, 2026, the record date for the Annual Meeting, are entitled to receive notice of, and to vote at, the Annual Meeting or any adjournments or postponements thereof. The record date is established by our Board. Stockholders are entitled to one vote for each share of our common stock that they owned as of the record date. On the record date, we had 192,940,493 shares of our common stock outstanding and entitled to vote at the Annual Meeting.  |

---

A complete list of such stockholders will be available for examination, by any stockholder, at our offices in Chicago, Illinois during normal business hours for a period of ten days before

the Annual Meeting. Please contact our Corporate Secretary, Rachel W. Mantz, at (312) 985-2000 if you wish to inspect the list of stockholders before the Annual Meeting.

Our stock trades on the New York Stock Exchange ("NYSE") under the ticker "TRU."

Q: What do I need to do to attend and participate in the Annual Meeting virtually?

---

| | |
|:---|:---|
| A: | Both stockholders of record and stockholders whose shares are held in street name (defined below) will be able to attend the Annual Meeting via live audio webcast, submit their questions during the meeting and vote their shares electronically at the Annual Meeting by visiting <u>www.virtualshareholdermeeting.com/TRU2026</u>. To participate in the Annual Meeting, you will need the control number included on your Notice or proxy card. If you do not have a control number, please contact your broker, banker or other nominee as soon as possible so that you can be provided with one.  |

---

We have designed our virtual format to enhance your access, participation and communication and we are committed to ensuring, to the extent possible, that stockholders will be afforded the ability to participate at the virtual meeting similarly to how they would participate at an in-person meeting. As part of the Annual Meeting, we will answer questions following the presentation of each proposal to be voted on at the Annual Meeting, and will hold a live online Q&A session, during which we intend to answer questions submitted before or during the Annual Meeting, as time permits. Questions must be confined to matters properly brought before the Annual Meeting and/or of general Company concern. We reserve the right to edit profanity or other inappropriate language, or to exclude questions that are not pertinent to meeting matters or that are otherwise inappropriate. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition. We kindly ask stockholders not to ask more than two <br>

------

##### [**Table of Contents**](#toc)
questions in order to allow us to answer questions from as many stockholders as possible. Questions may be submitted during the Annual Meeting through <u>www.virtualshareholdermeeting.com/TRU2026</u>.

The Annual Meeting live audio webcast will begin promptly at 12:00 p.m. Central Daylight Time on Tuesday, May 12, 2026. We encourage you to access the meeting prior to the start time. Online check-in will begin at 11:45 a.m. Central Daylight Time, and you should allow ample time for the check-in procedures. <br>

Q: What is the difference between holding shares as a registered stockholder and as a beneficial owner or in street name?

---

| | |
|:---|:---|
| A: | If your shares were registered directly in your name as of the record date with our transfer agent, Equiniti Trust Company, LLC, you are considered the "registered stockholder" of those shares. As a stockholder of record, we will mail the Notice, or if requested, copies of the proxy materials directly to you.  |

---

If your shares are held in a stock brokerage account or by a bank or other nominee ("street name"), you are considered the "beneficial owner" of the shares that are registered in street name. In this case, the Notice or, if requested, printed proxy materials and our 2025 Annual Report were forwarded to you by your broker, bank or other nominee. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares by following the voting instructions included in the materials, and your broker is not allowed to vote your shares without instruction except for certain matters. However, because a beneficial owner whose shares are held in street name is not the stockholder of record, you may not vote your shares of our common stock virtually at the Annual Meeting unless you follow your broker, bank or other nominee's procedures for obtaining a legal proxy. <br>

Q: What is a proxy?

---

| | |
|:---|:---|
| A: | A proxy is your legal designation of another person, called a proxy holder, to vote the shares  |

---

that you own. If you designate someone as your proxy holder in a written document, that document is called a proxy. We have designated Heather J. Russell, Executive Vice President, Chief Legal Officer, and Rachel W. Mantz, Senior Vice President, Deputy General Counsel and Corporate Secretary, to act as proxy holders at the virtual Annual Meeting as to all shares for which proxies are returned or voting instructions are provided by internet or telephonic voting.

---

| | |
|:---|:---|
| Q: | What routine matters will be voted on at the Annual Meeting?  |

---

---

| | |
|:---|:---|
| A: | The ratification of the appointment of our independent registered public accounting firm is a routine matter on which brokers may vote in their discretion on behalf of customers who have not provided voting instructions; however, certain brokers will not vote on such matters unless they have received voting instructions from their customers.  |

---

---

| | |
|:---|:---|
| Q: | What non-routine matters will be voted on at the Annual Meeting?  |

---

---

| | |
|:---|:---|
| A: | The election of our directors, the non-binding advisory vote on our NEOs' compensation and the advisory vote on a stockholder proposal requesting a stockholder right to call a special meeting are each non-routine matters on which brokers are not allowed to vote unless they have received voting instructions from their customers. Brokers who do not receive voting instructions will only be allowed to vote on the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal year 2026, provided such brokers provide discretionary voting.  |

---

Q: Could other matters be decided at the Annual Meeting?

---

| | |
|:---|:---|
| A: | We are not aware of any matters that will be considered at the Annual Meeting other than those described in this proxy statement. However, if any other matters properly arise at the Annual Meeting, the persons named in your proxy will vote in accordance with their best judgment.  |

##### [**Table of Contents**](#toc)

---

| | |
|:---|:---|
| Q: | How does the Board recommend that I vote?  |

---

---

| | |
|:---|:---|
| A: | The Board recommends that you vote:  |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "**FOR**" the election of each of the 12 director nominees named in this proxy statement as a director for a one-year term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "**FOR**" the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal year 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "**FOR**" the approval, on a non-binding advisory basis, of our NEO compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "**AGAINST**" the stockholder proposal requesting a stockholder right to call a special meeting.

---

| | |
|:---|:---|
| Q: | What is the vote required for each proposal?  |

---

---

| | |
|:---|:---|
| A: | For **Proposal 1**, *Election of Directors*, to be elected, each director nominee must receive a majority of the votes cast (the number of shares voted "FOR" a director nominee must exceed the number of votes cast "AGAINST" that nominee). Any incumbent director who fails to receive the required number of votes for re-election is required to promptly tender his or her resignation, and the NCG Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. Taking into account the recommendation of the NCG Committee, the Board will determine whether to accept or reject any such resignation, or what other action should be taken, within 90 days from the date of the certification of election results. We will publicly disclose any such decision by the Board with regard to any director's resignation. If you hold your shares in street name and do not give your broker specific voting instructions, your shares will not be voted and will not be counted in the election of the director nominees. Abstentions and broker non-votes will have no effect on the outcome of Proposal 1.  |

---

For **Proposal 2**, *Ratification of Appointment of Independent Registered Public Accounting Firm*, the proposal will be approved if a majority of the shares present or represented at <br>

the Annual Meeting and entitled to vote on the proposal are cast "FOR" the proposal. As Proposal 2 is advisory and non-binding, the Board will review the voting results on this proposal and take the results into account when making future decisions regarding this matter. Broker non-votes (described below) may be voted at the discretion of the broker or other nominee with respect to Proposal 2. Abstentions will have the effect of a vote against Proposal 2.

For **Proposal 3**, *Non-Binding Advisory Vote to Approve Named Executive Officer Compensation*, the proposal will be approved if a majority of the shares present or represented at the Annual Meeting and entitled to vote on the proposal are cast "FOR" the proposal. As Proposal 3 is advisory and non-binding, the Board will review the voting results on this proposal and take the results into account when making future decisions regarding this matter. Broker non-votes will have no effect on the outcome of Proposal 3. Abstentions will have the effect of a vote against Proposal 3. <br>

For **Proposal 4**, *Advisory Vote on a Stockholder Proposal Requesting a Stockholder Right to Call a Special Meeting*, the proposal will be approved if a majority of the shares present or represented at the Annual Meeting and entitled to vote on the proposal are cast "FOR" the proposal. As Proposal 4 is advisory and non-binding, the Board will review the voting results on this proposal and take the results into account when making future decisions regarding this matter. Broker non-votes will have no effect on the outcome of Proposal 4. Abstentions will have the effect of a vote against Proposal 4. <br>

---

| | |
|:---|:---|
| Q: | What is a broker non-vote?  |

---

---

| | |
|:---|:---|
| A: | NYSE permits brokers to vote their customers' stock held in street name on routine matters when the brokers have not received voting instructions from their customers. NYSE does not, however, allow brokers to vote their customers' stock held in street name on non-routine matters unless they have received voting instructions from their customers. In such cases, the uninstructed shares for which the broker is unable to vote are called "broker non-votes." For purposes of determining  |

---

------

##### [**Table of Contents**](#toc)
the outcome of any proposal as to which the broker has physically indicated on the proxy that it does not have, or chooses not to exercise, discretionary authority to vote, if allowed, these shares will be treated as not present and not entitled to vote with respect to that proposal, even though those shares are considered entitled to vote for quorum purposes.

Q: What is the effect of an abstention?

---

| | |
|:---|:---|
| A: | A stockholder who abstains on some or all matters is considered present for purposes of determining if a quorum is present at the Annual Meeting. Abstentions will have no effect on the outcome of Proposal 1 and will have the effect of a vote against Proposals 2 through 4.  |

---

Q: What constitutes a quorum?

---

| | |
|:---|:---|
| A: | A majority of the aggregate voting power of the common stock entitled to be voted at the Annual Meeting is a quorum, which is required for holding and transacting business at the Annual Meeting. The shares may be present virtually or represented by proxy at the Annual Meeting. Both abstentions and broker non-votes are counted as present for the purpose of determining the presence of a quorum.  |

##### [**Table of Contents**](#toc)
Q: Why did I receive a Notice of Internet Availability of Proxy Materials instead of printed proxy materials?

---

| | |
|:---|:---|
| A: | Most stockholders received a Notice instead of a full set of printed proxy materials. The Notice provides access to proxy materials in a fast and efficient manner via the internet. This reduces the amount of paper necessary to produce these materials, as well as the costs associated with mailing these materials to stockholders. On or around March 24, 2026, we will begin mailing the Notice to certain stockholders of record as of the close of business on March 16, 2026, and we will post our proxy materials on the website referenced in the Notice.

CORPORATE GOVERNANCE AND RELATED MATTERS

General

TransUnion is a global information and insights company with approximately 13,800 associates operating in more than 30 countries. We make trust possible by ensuring each person is reliably represented in the marketplace. We do this with a Tru<sup>™</sup> picture of each person: an actionable view of consumers, stewarded with care. Through our acquisitions and technology investments we have developed innovative solutions that extend beyond our strong foundation in core credit into areas such as marketing, fraud, risk and advanced analytics. As a result, consumers and businesses can transact with confidence and achieve great things. We call this Information for Good<sup>®</sup>.

Our Board directs the management of our business and affairs and also oversees our business on behalf of our stockholders. The Board and management recognize that the interests of TransUnion and our stockholders are advanced by responsibly addressing the concerns of multiple constituencies, including employees, consumers, customers and the communities in which we operate. Our Corporate Governance Guidelines support the Board in its oversight role and in fulfilling its obligation to stockholders.

Our Corporate Governance Guidelines address, among other things:

• the composition and responsibilities of the Board,

• director independence and qualification standards,

• Board meeting requirements,

• management succession planning,

• compensation of non-management directors, and

• communications with Board members.

The NCG Committee regularly reviews our Corporate Governance Guidelines and recommends modifications of these guidelines to the Board when appropriate, including when NYSE and SEC regulations require changes.

You can find our Corporate Governance Guidelines on our Investor Relations website, <u>investors.transunion.com</u>, on the "Corporate Governance—Governance Documents" page.

Board Leadership Structure and Role of Board in Risk Oversight

#### Board Leadership Structure
Our Board of Directors is currently led by Ms. Pamela Joseph, our Non-Executive Chairperson. Whenever the Chairperson of the Board is also the Chief Executive Officer ("CEO") or is a director who does not otherwise qualify as an "independent director," the independent directors will elect from among themselves a Lead Director of the Board. In such instance, following nomination by the NCG Committee, each independent director will be given the opportunity, by secret ballot, to vote in favor of a Lead Director nominee or to write in a candidate of his or her own. The Lead Director will be elected by a plurality and will serve until the Board meeting immediately following the next annual meeting of stockholders, unless otherwise determined by the Board. Since the CEO position is currently separate from our Chairperson position, we do not have a Lead Director at this time.

We believe that the separation of the Chairperson and the CEO roles is appropriate for us at this time. The Board believes that this leadership structure is appropriate because it strikes an effective balance between management and independent director participation in the Board process. The Non-Executive Chairperson role allows our President & CEO to focus on his management responsibilities in leading the business, setting our strategic direction and optimizing our performance and operations. At the same time, the Non-Executive Chairperson can focus on Board leadership, provide guidance to the CEO, and focus on corporate governance and our overall business strategy. The Board believes that the separation of functions between the CEO and the Non-Executive

------

##### [**Table of Contents**](#toc)
Chairperson of the Board provides independent leadership of the Board in the exercise of its oversight responsibilities, increases the accountability of the CEO and creates transparency into the relationship among executive management, the Board and our stockholders.

#### Role of the Board in Risk Oversight
The Board of Directors has extensive involvement in the oversight of risk management related to TransUnion and our business, which is implemented through regular reporting to the Board by the Audit Committee and Risk and Compliance Committee.

The Audit Committee reviews our accounting, reporting and financial practices, including the quality and integrity of our financial statements and our financial reporting and disclosure practices, the soundness of our internal controls over financial reporting, and, together with the Risk and Compliance Committee, our compliance with applicable legal and regulatory requirements. The Audit Committee reviews and discusses with management, our independent auditor and the Risk and Compliance Committee, our guidelines and policies governing the process by which risk assessment and enterprise risk management are undertaken, including our major financial and other risk exposures, and the steps management has taken to monitor and mitigate the risk of such exposures. The Audit Committee also periodically reviews with management (including the Chief Legal Officer) and our independent auditor, any correspondence with, or other action by, regulators or governmental agencies, and any employee complaints, submissions or published reports that raise concerns regarding our financial statements, accounting or auditing matters, or compliance with law or our Code of Business Conduct.

The Risk and Compliance Committee oversees the Company's risk management, as outlined in the Global Risk Taxonomy approved by our Enterprise Risk Management Committee ("ERMC"), a management-level committee chaired by our Chief Risk and Compliance Officer and consisting of our CEO, his direct reports and our Chief Information Security Officer. The Risk and Compliance Committee also oversees the assessment of the quality and effectiveness of our capabilities, policies and controls (including the methods of identifying, assessing, monitoring and mitigating such risks), and review of our enterprise risk management framework, enterprise risk appetite, compliance infrastructure and material risk exposures. The Risk and Compliance Committee periodically reviews and approves our Global Risk Appetite Statement, which summarizes our approach to taking, managing and responding to risks, and provides parameters to guide management on risk decisions. The ERMC sets our risk strategy within the boundaries of our Global Risk Appetite Statement and escalates certain issues to the Risk and Compliance Committee, or other relevant Board committees, as appropriate. The Risk and Compliance Committee also oversees the quality and effectiveness of our information security framework – including capabilities, policies and controls, and methods for identifying, assessing and mitigating information and cybersecurity risks – and assesses the effectiveness of our management of information security-related risks. The committee meets periodically with our Chief Legal Officer, Chief Risk and Compliance Officer, Chief Information Security Officer and other appropriate legal, risk or compliance staff to review any legal or regulatory matters that may have a material impact on our business or operating strategy.

As described above, through regular meetings with management, including the finance, legal, risk and compliance and internal audit functions, the Audit Committee and Risk and Compliance Committee review and discuss the significant areas of risk to our business and summarize for the Board areas of compliance risk and appropriate mitigating factors. In addition, our Board receives periodic operating performance reviews from management.

#### Executive Sessions of the Board
Our non-management directors regularly meet in executive sessions without management present. Ms. Joseph, our Board Chairperson, presides at such sessions.

Director Independence

Our Board has affirmatively determined that each of Mses. Clark, Joseph, Yarkoni and Zukauckas, Dr. Awad and Messrs. Chakraborty, Dia, Fradin, Gottdiener, Kumar and Monahan has no material relationship with the Company and qualifies as an independent director under the standards established by NYSE, as currently in effect.

In making that determination, the Board considered all relevant facts and circumstances, including the director's commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, and applied the following standards under NYSE rules, which provide that a director will not be considered independent if he or she:

• is currently an employee of the Company or has an immediate family member who is one of our executive officers;

• has been a Company employee within the past three years or has an immediate family member who has been an executive officer within the past three years;

• has, or has an immediate family member who has, received within the past three years more than $120,000 during any 12-month period in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service), and other than a family member's compensation for service as a non-executive employee;

• is a current partner or employee of a firm that is our internal or external auditor; has an immediate family member who is a current partner of such a firm; has an immediate family member who is a current employee of such firm and personally works on our audit; or was, or has an immediate family member who was within the last three years, a partner or employee of such a firm and personally worked on our audit within that time;

• has, or has an immediate family member who has, been employed as an executive officer of another company where any of our present executives have served on the other company's compensation committee during the past three years; or

• is currently employed as an executive officer or employee, or has an immediate family member who is currently employed as an executive officer, of another company that makes payments to, or receives payments from, the Company for property or services in an amount which, in any single fiscal year, exceeds the greater of (a) $1 million or (b) 2% of such other company's consolidated gross revenues.

The purpose of the independence review by our Board is to determine whether any such relationships or transactions were material and, therefore, inconsistent with a determination that the director or director nominee is independent. As a result of its review of our nominees for director, the Board determined that Mses. Clark, Joseph, Yarkoni and Zukauckas, Dr. Awad and Messrs. Chakraborty, Dia, Fradin, Gottdiener, Kumar and Monahan are independent under NYSE rules. Mr. Cartwright does not qualify as an independent director because he is currently the President & CEO of the Company. There are no family relationships between any of the nominees for director or between any nominee and any executive officer of our Company.

Mandatory Retirement

Any director who reaches age 75 while in office must resign when he or she reaches the age of 75. A director elected to the Board before his or her 75th birthday may continue to serve until the later of (1) the expiration of the director's then-current term and (2) the annual stockholders' meeting coincident with or next following his or her 75th birthday. On the recommendation of the NCG Committee, the Board may waive this requirement as to any director if the Board deems such waiver to be in the best interest of the Company.

------

##### [**Table of Contents**](#toc)
No Term Limits

The Board believes we benefit from the service of directors who have developed, through valuable experience over time, an increasing insight into the Company and its operations. The NCG Committee will review periodically the appropriateness of each director's continued service.

Stockholder Engagement

We employ a broad stockholder engagement program that provides management and our Board with valuable insight and feedback from investors throughout the year. Senior management communicated with investors throughout the year by means of quarterly press releases, conference calls, investor conferences and in-person meetings. We also conducted hundreds of additional investor calls throughout the year. During 2025, we engaged with stockholders representing more than 65% of our outstanding common stock and with more than 85% of actively managed shares. Key areas of focus for our discussions included financial and operating performance, strategic initiatives (including our ongoing transformation program), long-term growth opportunities and capital allocation.

Throughout the year, we also reached out to some of our largest stockholders to specifically understand their expectations related to corporate governance, environmental and social matters, including expectations related to Board members' skills and experience; responsible usage of emerging technologies such as artificial intelligence ("AI"); risk management standards; and efforts around financial inclusion.

Proxy Access

Our Fifth Amended and Restated Bylaws ("Bylaws") contain a proxy access provision, which enables an eligible stockholder, or a group of up to 20 stockholders, owning at least three percent (in aggregate, if applicable) of our outstanding common stock continuously for at least three years, to nominate and include in our proxy materials director nominees constituting up to the greater of two nominees or 20% of the number of directors on the Board that the common stockholders are entitled to elect, provided that the nominating stockholders and the proposed Board nominees satisfy the requirements in our Bylaws. If an eligible stockholder or group of stockholders wishes to nominate one or more director candidates to be included in our proxy statement for the 2027 Annual Meeting of Stockholders, our Corporate Secretary must receive the proposal at our principal executive offices at 555 West Adams Street, Chicago, Illinois 60661 between October 25, 2026 and November 24, 2026.

Communications with Directors

We have established a process for communications with directors. Stockholders and other interested parties may communicate with the Board, the Board Chairperson (or Lead Director), or the non-management directors as a group, regarding bona fide questions or concerns, by transmitting correspondence by mail or e-mail addressed as follows: Corporate Secretary (Rachel Mantz, rachel.mantz@transunion.com), 555 West Adams Street, Chicago, Illinois 60661. The Corporate Secretary will regularly forward such communications or a summary thereof to the Board or the applicable director(s). Such communications may be made confidentially or anonymously.

Meetings and Meeting Attendance

During 2025, each of our directors attended at least 75% of the Board and Board committee meetings on which he or she served (held during the period that such director served). Our Board met eight times during 2025.

Directors are expected to attend our annual stockholders' meeting. For our 2025 Annual Meeting of Stockholders, all members of our Board who were then-serving attended the meeting.

Sustainability Overview

We are dedicated to making meaningful, positive contributions to the world and the communities we serve. We are making an impact through our commitments to enabling life-changing access to credit in mature and emerging markets and using technology innovation to help consumers improve their access to credit while doing good for people and the planet.

At the Board level, TransUnion's sustainability program (including energy efficiency and other sustainability-related risks and matters) is overseen by the NCG Committee. The NCG Committee receives updates from management on such matters on a quarterly basis.

#### Sustainability Program
We strive to maintain a comprehensive program across the sustainability issues most salient to our business and measure our progress in these areas. As discussed below, our sustainability program focuses on enhancing financial inclusion; maintaining robust corporate governance, compliance and security programs; supporting our workforce and the communities in which we do business; and managing our environmental impact.

*Financial Inclusion* 

Our business, at its core, is grounded in increasing financial inclusion and economic opportunity. To us, financial inclusion means ensuring individuals and businesses have equal access to affordable financial products and services, including credit, to meet their needs when it comes to building wealth and managing risks. As a pioneer in alternative and trended credit data, we leverage the data assets we steward to help create a more robust picture of consumers whose credit risk can be difficult to accurately assess using only traditional scoring methods. We also foster consumer education through our various partnerships and charitable contributions, and we underpin our financial inclusion efforts with policy support and research.

*Governance, Compliance and Security* 

We maintain robust governance, compliance and security programs to promote alignment with the requirements of our industry and to uphold our high standards.

• *Corporate Governance Practices* —We maintain a corporate governance program that upholds high ethical, legal and industry standards. Management regularly reports to the NCG Committee regarding our corporate governance program and seeks the committee's input regarding any proposed modifications to our governance structure.

• *Business Ethics* —We handle sensitive information that we use to help individuals make life-changing decisions every day. To help secure sensitive data, we place great importance in training and holding our employees accountable for compliance with all applicable legal and ethical standards. Furthermore, to promote the high ethical standards required to conduct our business, we maintain several programs, policies and processes. For example, our Code of Business Conduct describes the standards by which we operate with each other, our consumers, customers, vendors and business partners. In order to ensure that our associates, officers and Board members are well-informed and have the guidance to act in a manner consistent with our values, everyone at TransUnion is required to review and affirm the Code of Business Conduct annually. The Audit Committee and Risk and Compliance Committee periodically review with management any correspondence with, or other action by, regulators or governmental agencies, and any employee complaints, submissions or published reports that raise concerns regarding compliance with our Code of Business Conduct.

• *Data Security* —The security and protection of personal data is our highest priority. We are committed to aligning with industry-leading cyber risk management best practices and complying with all applicable legal and regulatory requirements. Our Information Security program is based on ISO/IEC 27001:2022 principles, including a global-level Information Security Department that develops our

------

##### [**Table of Contents**](#toc)
security policies, standards and procedures, and we consistently evolve our approach to protect against increasing security threats around the world. At the Board level, our Risk and Compliance Committee is responsible, on behalf of the Board, for oversight of our compliance with applicable global data privacy and security regulations and requirements, and assesses the effectiveness of systems, controls and procedures we use to facilitate compliance with such requirements. The Risk and Compliance Committee also oversees the quality and effectiveness of our information security framework and assesses the effectiveness of our management of information security-related risks. At the management level, the ERMC sets our risk strategy within the boundaries of our Global Risk Appetite Statement. We regularly engage independent third-party organizations to conduct independent security assessments, and we maintain a Third Party Risk Management program, performing risk management assessments of our vendors, and continuously monitoring third-party risk on topics including sustainability. <br>

• *Artificial Intelligence* —We approach new technologies from a security-first standpoint to protect the data we steward. Our intentional, responsible approach to new technology selection and adoption, including AI, is rooted in our evolving AI Principles, which align with our mission, values and beliefs. Our cross-functional, management level, Data Risk Committee (the "DRC") is responsible for implementing processes to efficiently and effectively manage risks associated with data, including analytics and model governance, and our use of emerging technologies, including AI. The DRC developed an AI risk assessment framework and is responsible for monitoring the full landscape of emerging global AI regulations and adapting the framework in accordance with changes to applicable regulations and technologies. The DRC escalates issues to the ERMC, as appropriate, which works to align the risks related to AI-use within the scope of our Global Risk Appetite Statement. The ERMC escalates AI-related risk issues to the Risk and Compliance Committee, as appropriate. We have started incorporating human-supervised AI to drive efficiency on our teams; it helps to automate workflows and build better products. For additional details regarding our AI governance and the use of AI at TransUnion, please see our 2025 Global Impact Report. For the avoidance of doubt, neither our 2025 Global Impact Report nor any disclosures included on our corporate website are incorporated by reference into this proxy statement.

• *Data Privacy* —TransUnion's business is based on innovative sourcing, processing and provisioning of data to internal and external stakeholders. Privacy compliance is of paramount importance to the ongoing operation of TransUnion, promoting a strong industry reputation, maintaining operational efficiency and positively affecting regulator, customer and investor confidence. We have invested significantly into enhancing our data privacy efforts in recent years. We maintain a global data privacy framework that governs and supports the management of data privacy across TransUnion. As part of that framework, we conduct privacy-focused assessments of changes to our products and processing activities for compliance with privacy regulations and alignment with consumer expectations. Our assessments consider the nature of the data use and notice made available to consumers, along with information security, individuals' privacy rights and expectations and any relevant data quality considerations. Our U.S. Privacy Committee and International Risk Management Committee oversee privacy risk in the U.S. and internationally, respectively, and escalate issues to the ERMC as appropriate. At the Board level, our Risk and Compliance Committee is responsible for oversight of our compliance with applicable global data privacy and security regulations and requirements, including any privacy risks escalated by the ERMC.

*People, Workforce and Communities* 

Our talented, highly trained employees bring their experience, perspective and creativity to their teams around the world. We support our employees by providing competitive benefits and development opportunities. Our workforce is comprised of approximately 13,800 knowledgeable and passionate employees around the world.

• *Wellbeing & Benefits* —When our associates are able to bring their best selves to the workplace, our business thrives. Our benefit programs are designed to provide associates with a safe and supportive

------

##### [**Table of Contents**](#toc)
work environment. In addition to the types of benefits employees have come to expect from a company of our size and industry – such as 401(k) matching and dental coverage – we also offer leading benefits such as hybrid work arrangements and caregiver support. We are also proud to offer mental health coverage globally to our associates and their families, so they are better able to manage the challenges they may face. <br>

• *Talent Acquisition & Retention* —We see our people as a source of strength and know that they are essential to our mission, innovation and growth. Our talent acquisition team works to find the best talent for each role, through merit and skills-based hiring practices. We promote a comprehensive and unbiased supportive environment that encourages individual merit and performance.

• *Communities* —TransUnion recognizes the importance of having a robust supply chain. We invest in building relationships with small businesses in the communities where we operate, helping create prosperity for all. Additionally, through our GoodWorks@TU program, we give back to the communities where we operate with volunteerism and philanthropic donations. Our teams organize group volunteer efforts, including a dedicated month of service every April, and many of our associates commit their personal time to a variety of causes.

We value our people and communities and work diligently to provide expanded, merit-based opportunities for all in and outside the workplace. We are dedicated to providing a welcoming and growth-oriented work environment that enables our people to reach their full potential. We aim to promote these initiatives in accordance with applicable legal frameworks in our various operations around the globe.

*Energy and Environment* 

TransUnion maintains a holistic energy efficiency strategy to reach our climate targets, identify efficiencies, and reduce our impact on the environment. Our strategy is designed to help us meet our climate targets by focusing on the way we impact the environment the most – energy consumption.

In 2021, we set two targets, to achieve operational net zero Scope 1 and Scope 2 market-based greenhouse gas ("GHG") emissions by 2025 and 30 percent reductions on leased real estate Scope 3 emissions by 2030, using 2019 as a baseline. We achieved our 2025 goal through a combination of actual emission reductions, primarily through the purchase of renewable energy (including market instruments such as renewable energy certifications), real estate consolidation and the use of carbon offsets to address certain residual GHG emissions.

We continue to pursue reductions of our Scope 3 emissions, including those associated with our leased real estate emissions goal through efforts such as our real estate consolidation strategy. This allows us to more efficiently use our office space, thereby reducing our costs and environmental impact. As we continue to reduce emissions through renewable energy purchases (including through renewable energy certificates), we are also purchasing carbon offsets to help mitigate the impact of emissions that we have been unable to eliminate.

More information on our sustainability practices, our emissions calculations and associated methodology, as well as certain information regarding our approach to sustainability disclosures and related risks, is available in our 2025 Annual Report on Form 10-K and our 2025 Global Impact Report (which Global Impact Report, for the avoidance of doubt, is not incorporated herein by reference).

Considerations for Board Nominees

When considering whether directors and nominees have the experience, qualifications, attributes and skills to enable our Board to satisfy its oversight responsibilities effectively in light of our business and structure, the Board focused primarily on each person's background and experience as reflected in the information discussed below in the section titled "Background and Experience of Directors" and each of the directors' individual biographies. We believe that our directors provide an appropriate mix of experience and skills relevant to the size and nature of our business.

------

##### [**Table of Contents**](#toc)
Our NCG Committee is responsible for reviewing the qualifications of potential director nominees and recommending candidates to the Board for nomination for election to the Board, and recommending whether Board members should stand for reelection. Our Corporate Governance Guidelines and NCG Committee charter set forth the selection criteria for evaluating potential director nominees, including, but not limited to, a potential candidate's strength of character, mature judgment, industry knowledge or experience, independence of thought, ability to work collegially with other members of the Board and any other factors the NCG Committee considers appropriate. Each individual is evaluated in the context of the Board as a whole, with the objective of recommending a group that can best steer the success of our business.

The NCG Committee also considers differences of professional experience, viewpoint, individual characteristics, qualities and skills, resulting in naturally varying perspectives among the directors. The NCG Committee considers candidates with demonstrated skills or experience in the following areas, among others: business or regulatory acumen, industry knowledge and experience, relevant career experience and financial experience, as well as those skills listed in the "Background and Experience of Directors" table set forth on page 21. The NCG Committee may also consider the extent to which a candidate would fill a present need on the Board.

In identifying qualified candidates for our Board, our NCG Committee reviews candidates' existing commitments to other businesses and potential conflicts of interest with other pursuits. The NCG Committee evaluates legal considerations such as antitrust issues, corporate governance background, financial and accounting background, executive compensation background and the size, composition and combined expertise of the existing Board. Our NCG Committee will consider director candidates from many sources, including stockholders. Stockholder recommendations must follow certain procedures under SEC rules and regulations and our Bylaws. Any such recommendations must be in writing and delivered to the NCG Committee at the following address: Corporate Secretary, 555 West Adams Street, Chicago, Illinois 60661. The NCG Committee will evaluate all candidates for the Board in the same manner, including those candidates proposed by stockholders.

Our Third Amended and Restated Certificate of Incorporation provides for an unclassified Board. At the Annual Meeting, all director nominees elected by our stockholders will be elected to hold office for a term of one year, or until their successors are duly elected and qualified.

Board Evaluations

Our Board and each of its committees perform an annual self-assessment to evaluate their effectiveness in fulfilling their respective obligations. In 2025, we engaged an independent third party (the "Board Consultant") to assist us with completing the assessment. Topics in the assessment included a review of the Board's roles and responsibilities, meetings, compensation, access to information, Board composition, communications and additional matters. A summary identifying any themes or issues that emerged in the evaluations was presented to the Board on an anonymous basis and was reviewed and discussed by the Board in a non-executive session, led by the Board Consultant. The NCG Committee also uses the results of the annual evaluations to periodically consider the mix of skills and experience the directors bring to the Board to assess whether the Board has the necessary tools to perform its oversight function effectively.

Each committee also conducts its own annual self-evaluation and reports the results to the chairperson of the applicable committee and the Chairperson of the Board, including a comparison of the committee's performance against the requirements of its written charter. Feedback received from committee evaluations is compiled anonymously and reviewed and discussed by the committee members in a non-executive session annually, and addressed with management, as appropriate. Pursuant to its charter, the NCG Committee also periodically reviews the performance of each committee and makes recommendations to the Board for the creation of additional, or elimination of existing, committees.

Management Succession Planning

The Board and the Compensation Committee require senior management to report (at least annually) on succession planning, which includes, among other things, an assessment of the experience, performance and

------

##### [**Table of Contents**](#toc)
skills for possible successors to the CEO and other executive officer positions. The Board collaborates with senior management to ensure that effective plans are in place for management succession, including reviewing succession plans relating to the CEO and other executive officer positions, as well as potential successors to those who occupy these positions. Additionally, pursuant to its charter, the Compensation Committee oversees and approves the management continuity planning process. This includes reviewing and encouraging the adoption of programs that provide for the identification and development of executives and other critical talent with an emphasis on CEO and executive officer succession matters. The Compensation Committee reports periodically to the Board on succession planning.

Background and Experience of Directors

Our director nominees reflect a wide range of backgrounds, skills and experiences, ranging from government relations to several current and former CEOs from varying industries. We believe that identifying the primary skills of our directors provides a meaningful representation of the balance of skills of our Board as a whole. Our directors' individual viewpoints and unique experiences enhance the quality of our Board's discussions and the ability to execute on our business strategy.

The table below, which is current as of March 16, 2026, highlights the experience and skills of our director nominees that we believe are critical to the success of TransUnion and are based on the findings from our ongoing stockholder engagement efforts.

Code of Business Conduct

We have adopted a Code of Business Conduct that applies to all directors, officers and employees. You can find our Code of Business Conduct on our Investor Relations website, <u>investors.transunion.com</u>, on the "Corporate Governance—Governance Documents" page, and a copy of the Code of Business Conduct may also be obtained free of charge upon a request directed to TransUnion, 555 West Adams Street, Chicago, Illinois 60661, Attn: Corporate Secretary.

In the event that we amend or waive provisions of the Code of Business Conduct that apply to our Chief Executive Officer, Chief Financial Officer, Principal Accounting Officer or Controller, and other senior financial officers performing similar functions, we intend to disclose the relevant information on our website.

Related Person Transactions

#### Related Person Transactions Policies and Procedures
Our Board of Directors has adopted a written Related Person Transaction Policy, which provides that any "Related Person Transaction" must be reviewed and approved or ratified in accordance with specified procedures. The term "Related Person Transaction" includes any transaction, arrangement or relationship, or series of similar transactions, arrangements or relationships, in which (1) the aggregate dollar amount involved exceeds $120,000 in any fiscal year, (2) the Company is, or is proposed to be, a participant, and (3) any person who is or was (since the beginning of the last fiscal year) a director, a nominee for director, an executive officer or a beneficial owner of more than five percent of any class of our voting securities, or a member of the immediate family of any such person, had, has or will have a direct or indirect material interest (other than solely as a result of being a director or being less than a five percent beneficial owner of another entity) (collectively, a "Related Person").

Our policy requires each director, nominee and executive officer to notify the Executive Vice President, Chief Legal Officer in writing of any potential Related Person Transaction in which the director, nominee, executive officer or an immediate family member has or will have an interest and to provide specified details of the transaction. The Executive Vice President, Chief Legal Officer will deliver a copy of the notice to the Audit Committee, which will then review the relevant facts and circumstances of each proposed Related Person Transaction and approve, ratify or disapprove the transaction.

The vote of a majority of disinterested members of the Audit Committee is required to approve or ratify any Related Person Transaction. The Audit Committee may approve or ratify a Related Person Transaction if the Audit Committee determines, in its business judgment, based on the review of all available information, that the transaction is fair and reasonable to the Company, that there is a business or corporate interest supporting the Related Person Transaction, and that the Related Person Transaction is in the best interests of the Company.

------

##### [**Table of Contents**](#toc)
In making this determination, the Audit Committee will consider, among other things:

• the business or corporate purpose of the transaction;

• whether the transaction is entered into on an arms-length basis and on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances;

• whether the transaction would impair the independence of the director or executive officer;

• whether the transaction would otherwise present an improper conflict of interest; and

• whether the transaction would violate any law or regulation applicable to us or any provision of our Code of Business Conduct.

The policy also contains categories of pre-approved transactions, which do not require further review by the Audit Committee, including the following: (1) any transaction that involves compensation to a Board member or an executive officer that is reportable under SEC rules; (2) indemnification and advancement of expenses made pursuant to our organizational documents; (3) any transaction with another company if the Related Person's only relationship with that company is as (a) a director or an employee of that company (other than an executive officer), (b) a beneficial owner of less than five percent of that company's outstanding equity, or (c) in the case of partnerships, a limited partner, and the Related Person and all other Related Persons have an aggregate interest of less than five percent in the partnership; (4) charitable contributions, grants or endowments by TransUnion to a charitable organization or university if the Related Person's only relationship to such organization is as an employee (other than an executive officer) or a director or trustee; and (5) transactions involving rates or charges that are determined by competitive bids.

Compensation Committee Interlocks and Insider Participation

Messrs. Monahan (Chairperson), Fradin and Kumar and Ms. Joseph were members of the Compensation Committee during 2025. None of these individuals is or has been an officer or employee of the Company or is serving or has served as a member of the compensation committee of another entity that has an executive officer serving on our Compensation Committee. None of our executive officers serves on the board of directors or as a member of the compensation committee of another entity at which a member of our Compensation Committee serves as an executive officer. Additionally, none of our executive officers serves on the compensation committee of another entity at which a member of our Board serves as an executive officer.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the beneficial ownership of our common stock as of March 16, 2026, by:

• each person that is the beneficial owner of more than 5% of our outstanding common stock;

• each member of our Board;

• each of our "named executive officers" (as defined in the section titled "Compensation Discussion and Analysis" in this proxy statement); and

• all of the members of our Board and our executive officers as a group.

The information below is based on a total of 192,940,493 shares of our common stock outstanding as of March 16, 2026.

To our knowledge, unless otherwise disclosed in the footnotes to this table, and subject to applicable community property laws, we believe that the persons named in the table have sole voting and investment power with respect to their beneficially owned common stock.

Beneficial ownership for the purposes of the following table is determined in accordance with the rules and regulations of the SEC. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting thereof, or to dispose or direct the disposition thereof, or has the right to acquire such powers within 60 days. Shares of common stock subject to options that are currently exercisable or exercisable within 60 days of March 16, 2026 are deemed to be outstanding for calculating the percentage ownership of the person holding the options, but are not deemed outstanding for the purposes of calculating the percentage ownership of any other person. Unless otherwise indicated in the table or footnotes below, the address for each beneficial owner is c/o TransUnion, 555 West Adams Street, Chicago, Illinois 60661.

As a practical matter, we assist our directors and officers by monitoring transactions and completing and filing Section 16 reports on their behalf.

PROPOSAL 1: ELECTION OF DIRECTORS

Upon the recommendation of the Nominating and Corporate Governance Committee, our Board has nominated the 12 people named below for election as directors at our Annual Meeting. Each of the nominees for director has agreed to be named in this proxy statement and to serve as a director if elected.

#### Nominees :

#### Dr. George M. Awad

#### Christopher A. Cartwright

#### Sayan Chakraborty

#### Suzanne P. Clark

#### Hamidou Dia

#### Russell P. Fradin

#### Charles E. Gottdiener

#### Pamela A. Joseph

#### Thomas L. Monahan, III

#### Ravi Kumar Singisetti

#### Charlotte B. Yarkoni

#### Linda K. Zukauckas
If elected, each of the 12 director nominees will serve a term of one year on our Board, until our 2027 Annual Meeting of Stockholders or until their successors are duly elected and qualified in accordance with our Bylaws.

The affirmative vote of a majority of votes (meaning the number of shares voted "FOR" a nominee must exceed the number of shares voted "AGAINST" such nominee) cast virtually or represented by proxy and entitled to vote at the Annual Meeting will elect each of the 12 nominees for a one-year term. If any nominee for director receives a greater number of votes "AGAINST" his or her election than votes "FOR" such election, our Corporate Governance Guidelines provide that such person will tender to the Board his or her resignation as a director. The NCG Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken, and, taking into account the recommendation of the NCG Committee, the Board will determine whether to accept or reject such resignation, or what other action should be taken, within 90 days from the date of the certification of election results. We will publicly disclose any such decision by the Board with regard to any director's resignation. Unless instructions to the contrary are given, all properly delivered proxies will be voted "FOR" the election of these 12 nominees as directors.

In the event that any nominee for any reason is unable to serve, or for good cause will not serve, the proxies will be voted for such substitute nominee as our Board may determine. We are not aware of any nominee who will be unable to serve, or for good cause will not serve, as a director.

The relevant experiences, qualifications, attributes and skills of each nominee that led our Board to recommend each of the above persons as a nominee for director are described in the section titled "Background and Experience of Directors."

#### The Board of Directors recommends a vote "FOR" each of the foregoing nominees to serve as a director for a one-year term.
Director Compensation

The following table discusses the compensation earned by our non-employee directors in 2025. As of March 31, 2025, all of our non-employee directors were independent, as Mr. Gottdiener qualified as an independent director under the NYSE Listing Standards on such date. Mr. Cartwright, our President & CEO, is not included in the

------

##### [**Table of Contents**](#toc)
table below because he did not receive any additional compensation for his service on the Board. Mr. Cartwright's 2025 compensation is presented in the "Summary Compensation Table—2025" found on page 63.

The Compensation Committee annually reviews non-employee director compensation with its independent compensation consultant, FW Cook, to confirm that pay is aligned with the market and that of our Custom Comparator Group (as defined on page 51) used for executive compensation benchmarking, but is not excessive.

After its annual compensation review in May 2025, upon the recommendation of FW Cook, the Compensation Committee recommended, and the Board approved, a $20,000 increase (from $190,000 to $210,000) in the grant value of the annual restricted stock granted to our non-employee directors to align with our Custom Comparator Group.

In 2025, our non-employee directors were eligible for the annualized compensation amounts described below. The non-employee directors are paid on a quarterly basis for their service on our Board and Committees<sup>(1)</sup>:

---

| | |
|:---|:---|
|  Board of Directors' Annual Retainer | $95000 |
|  Board Chairperson Fee | $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;150000 |
|  Audit Committee Chairperson Fee | $30000 |

|  Nominating and Corporate Governance Committee Chairperson Fee | $20000 |
|  Mergers, Acquisitions and Integration Committee Chairperson Fee | $20000 |
|  Risk and Compliance Committee Chairperson Fee | $20000 |
|  Technology Committee Chairperson Fee | $20000 |
|  Committee Member Fees | $10000 |

---

(1) The Chairperson and members of the Executive Committee do not receive compensation for service on the Executive Committee.

In addition, in 2025, our non-employee directors received restricted stock grants with a grant value of $210,000 under our Second Amended and Restated 2015 Omnibus Incentive Plan ("Second Amended 2015 Plan"), which vest on the one-year anniversary of the grant date. The restricted stock grants provide the directors with the same rights as stockholders generally, including the right to receive dividends paid on our common stock.

The total compensation earned by our non-employee directors in 2025 is shown in the table below.

(1) The amounts shown in this column represent the full grant date fair value of the restricted stock grant in 2025 as computed in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718. Assumptions used in the calculation of these amounts are included in Note 16 "Stock-Based Compensation," of the consolidated financial statements contained in our 2025 Annual Report on Form 10-K. Dr. Awad, Messrs. Dia, Fradin, Gottdiener, Kumar and Monahan, and Mses. Clark, Joseph and Zukauckas each received a grant of 2,463 shares of restricted stock under our Second Amended 2015 Plan on May 7, 2025. These are the only outstanding restricted stock grants for each director as of December 31, 2025.

##### [**Table of Contents**](#toc)

#### Stock Ownership Requirements
We maintain a formal stock ownership policy requiring all non-employee directors to hold TransUnion common stock, which includes unvested restricted stock, in an amount equal to five times the Board of Directors' annual retainer. To attain the desired multiple, each director must retain 75% of the after-tax value of his or her shares received pursuant to any equity grant after January 1, 2016, until such multiple is achieved. All applicable directors have met their stock ownership requirements as of December 31, 2025.

#### Business Expenses
The non-employee directors are reimbursed for their business expenses related to their attendance at our meetings, including room, meals and transportation to and from Board and committee meetings. On rare occasions, a director's spouse may accompany a director when traveling on TransUnion business.

#### Director and Officer Liability ("D&O") Insurance
D&O insurance insures our individual directors and officers against certain losses that they are legally required to bear as a result of their actions while performing duties on our behalf. Our D&O insurance policy does not break out the premium for directors versus officers and, therefore, a dollar amount cannot be assigned to the coverage provided for individual directors.

PROPOSAL 2: RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed the independent registered public accounting firm of PricewaterhouseCoopers LLP to audit our consolidated financial statements for the year ending December 31, 2026. We are not required under SEC regulations to submit this proposal. However, the Board believes it is appropriate and a good corporate governance practice to do so.

Ratification of Appointment of PricewaterhouseCoopers LLP

The ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2026 will be approved if a majority of the shares present or represented at the Annual Meeting and entitled to vote on the proposal are cast "FOR" the proposal. Unless instructions to the contrary are given, all properly delivered proxies will be voted "FOR" ratification.

If the appointment is not ratified by the stockholders, the Audit Committee will consider the appointment of a different independent registered public accounting firm.

A representative of PricewaterhouseCoopers LLP is expected to be present at the virtual Annual Meeting, will be offered the opportunity to make a statement if such representative desires to do so and will be available to respond to appropriate questions.

**The Board of Directors recommends a vote "FOR" the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for fiscal year 2026.** 

Audit and Related Fees

The following table sets forth fees for audit services rendered by PricewaterhouseCoopers LLP for the audit of our annual financial statements and fees billed for other services for the years ended December 31, 2025 and 2024:

These services include due diligence related to business acquisitions and disposals, carve-out audits and attestation services.

------

##### [**Table of Contents**](#toc)
Our Audit Committee has established guidelines to approve services and fees for any non-audit services to be provided by our independent registered public accounting firm, all in accordance with applicable laws, regulations and rules. The Audit Committee may delegate authority to one or more independent members of the Audit Committee to grant pre-approvals of audit and permitted non-audit services, provided that any such pre-approvals will be presented to the full Audit Committee at its next scheduled meeting.

Notwithstanding the foregoing, pre-approval is not necessary for minor non-audit services if: (i) the aggregate amount of all such non-audit services provided constitutes not more than five percent of the total amount of revenue paid by TransUnion to our independent auditor during the fiscal year in which the non-audit services are provided; (ii) such services were not recognized by TransUnion at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Audit Committee and approved prior to the completion of the audit by the Audit Committee or by one or more members of the Audit Committee who are members of the Board to whom authority to grant such approvals has been delegated by the Audit Committee.

Audit Committee Report

The Audit Committee of our Board of Directors currently consists of the directors whose names appear below. Each member of the Audit Committee is "independent" and meets the financial literacy requirements of NYSE's listing standards.

PROPOSAL 3: NON-BINDING ADVISORY VOTE TO APPROVE

NAMED EXECUTIVE OFFICER COMPENSATION

As discussed in the section titled "Compensation Discussion and Analysis," which begins on page 43 of this proxy statement, the Board believes that our long-term success depends largely on the talents of our employees. Our compensation program plays a significant role in our ability to attract, retain and motivate the highest quality employees. The Board believes that our current compensation program directly links executive compensation to performance and the achievement of strategic goals, and aligns the interests of our executive officers with those of our stockholders.

This proposal provides stockholders with the opportunity to cast a non-binding advisory vote to approve the compensation program. This non-binding advisory vote is commonly referred to as a "Say-on-Pay" vote. The "Say-on-Pay" vote is being provided pursuant to SEC regulations. While the vote does not bind the Board to any particular action, the Board values the input of the stockholders, and will take into account the outcome of this vote in considering future compensation arrangements.

The Board encourages you to review carefully the sections titled "Compensation Discussion and Analysis" beginning on page 43 and "Executive Compensation" beginning on page 63, and to cast a non-binding advisory vote to approve our executive compensation programs through the following resolution:

"**RESOLVED**, that the compensation paid to TransUnion's named executive officers, as disclosed in the 2026 proxy statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby **APPROVED**."

In 2022, based on the results of the advisory stockholder vote held at the 2022 annual meeting of stockholders regarding the frequency of future "Say-on-Pay" votes, the Board determined "1 YEAR" as the frequency of our future Say-on-Pay votes. Unless the Board modifies its determination on the frequency of future "Say-on-Pay" advisory votes, the next Say-on-Pay vote will be held at the annual meeting of stockholders in 2027.

The compensation of our named executive officers as disclosed in this proxy statement will be approved, on a non-binding advisory basis, if a majority of the shares present or represented at the Annual Meeting and entitled to vote on the proposal are cast "FOR" the proposal. Unless instructions to the contrary are given, all properly delivered proxies will be voted "FOR" the approval of the compensation of our named executive officers.

**The Board of Directors recommends that you vote "FOR" the approval, on a non-binding advisory basis, of the compensation of our named executive officers as disclosed in this proxy statement.**

COMPENSATION DISCUSSION AND ANALYSIS

The information contained in this Compensation Discussion and Analysis ("CD&A") describes the material elements of compensation paid or awarded to our principal executive officer, principal financial officer, and our three other most highly compensated executive officers (collectively, our "named executive officers" or "NEOs") for the fiscal year ended December 31, 2025.

For 2025, our NEOs were:

In the Executive Summary section of this CD&A, we highlight our:

• 2025 Business Results;

• 2025 Annual Incentive Plan Performance;

• 2023 PSU Performance; and

• 2025 Executive Compensation Program Actions, Results and Changes.

In the remainder of this CD&A, we describe:

• How our executive compensation philosophy and governance practices align with stockholders' interests, reflect best practices and promote thoughtful decision-making while discouraging unnecessary and excessive risk taking (see page 46);

• The role of the Compensation Committee, management and compensation consultant in compensation decisions (see page 48);

• An overview of our NEOs' 2025 target compensation mix (see page 48);

• Key executive compensation components (see page 50);

• Our market analysis and benchmarking (see page 51); and

• Our 2025 executive compensation program (see page 52).

Executive Summary

#### 2025 Business Results
A summary of our consolidated results as reported in our 2025 Annual Report on Form 10-K, filed with the SEC on February 27, 2026, and our related earnings release for the year and fourth quarter ended December 31, 2025, is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Revenue of $4,576 million, an increase of 9% (10% on a constant currency basis)<br>• Consolidated Adjusted EBITDA of $1,646 million, an increase of 9% (10% on a constant currency basis)<br>• Adjusted Diluted Earnings Per Share of $4.30, an increase of 10%<br>• Consolidated Adjusted EBITDA margin was 36%, even with 36% in 2024<br>

------

##### [**Table of Contents**](#toc)
Constant currency growth rates assume foreign currency exchange rates are consistent between years. This allows financial results to be evaluated without the impact of fluctuations in foreign currency exchange rates. Our consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). In addition to GAAP measures, we use the non-GAAP measures of Consolidated Adjusted EBITDA, Consolidated Adjusted EBITDA Margin and Adjusted Diluted Earnings per Share as supplemental measures of our operating performance. For a more detailed explanation of why we present these measures, and how we calculate these non-GAAP measures and the reconciliation of these non-GAAP measures to their nearest GAAP measures, see our 2025 Annual Report on Form 10-K, under the heading "Non-GAAP Measures—Years Ended December 31, 2025, 2024 and 2023."

#### 2025 Annual Incentive Plan Performance
The following highlights the consolidated financial performance results used for our 2025 annual incentive plan. Our Defined Consolidated Adjusted EBITDA was $1,634.9 million, resulting in a payout of 139.8% of target; our Defined Consolidated Revenue was $4,548.1 million, resulting in a payout of 173.7% of target; and our Defined Adjusted Diluted Earnings per Share was $4.27, resulting in a payout of 169.0% of target. For all NEOs, Defined Consolidated Adjusted EBITDA has a 35% weighting, Defined Consolidated Revenue has a 35% weighting, and Defined Adjusted Diluted Earnings per Share has a 20% weighting. The remaining 10% is for each NEO's Strategic Individual Objectives. Our 2025 annual incentive plan, including individual objectives, applicable weightings and achievement is discussed in greater detail beginning on page 53 in the section titled "2025 Executive Compensation Program—Annual Incentive Plan."

![LOGO](g42958g09y25.jpg)

#### 2023 PSU Performance
The following summarizes the performance results for our performance share units ("PSUs") granted in February 2023 with a performance period of January 1, 2023 to December 31, 2025 (the "2023 PSUs"). The performance metrics used for these share-based grants consist of Cumulative Adjusted EBITDA, Cumulative Revenue and Relative Total Stockholder Return ("Relative TSR") performance over the performance period. These metrics are defined in the grant agreements and are similar, but not identical, to the performance metrics used for our 2025

------

##### [**Table of Contents**](#toc)
annual incentive plan as discussed above. In the context of our PSUs, both Cumulative Adjusted EBITDA and Cumulative Revenue include adjustments to remove the impact of currency fluctuation and inorganic growth. For purposes of this section, references to Cumulative Adjusted EBITDA, Cumulative Revenue and Relative TSR will have the meanings ascribed to them in the grant agreements. Overall, our Cumulative Adjusted EBITDA over the performance period was $4,523.2 million, resulting in vesting at 111% of target under this metric. Our Cumulative Revenue over the performance period was $12,390.0 million resulting in vesting at 200% of target under this metric. Our Relative TSR performance over the performance period was at the 62nd percentile resulting in vesting at 138% of target. For our 2023 PSUs, Cumulative Adjusted EBITDA has a 30% weighting, Cumulative Revenue has a 20% weighting, and Relative TSR has a 50% weighting, resulting in an overall weighted payout at 142% of target.

Our PSU performance is discussed in greater detail beginning on page 57 in the section titled "2025 Executive Compensation Program—Long-Term Incentive Plan—2023 PSU Performance."

![LOGO](g42958g50a01.jpg)

#### 2025 Executive Compensation Program Actions, Results and Changes
We took the following actions with respect to our NEOs and executive compensation program in 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mr. Cartwright received an increase to his target bonus percentage to better align with market benchmarks (see page 53).<br>• Mr. Cello received a base salary increase to better align his pay with peers and to market benchmarks (see page 52).<br>• Each of our NEOs received a payout under our 2025 annual incentive program at 154.0% of target based on corporate and individual performance (see page 55).<br>• Our NEOs, including our CEO, each received annual long-term incentive ("LTI") awards in the form of time-vesting RSUs and performance-vesting PSUs (see page 56).<br>• Mr. Abdelsadek and Mses. Chambers and Zuiker each received a sign-on equity grant in the form of time-vesting RSUs in connection with the commencement of their employment with TransUnion (see page 59).<br>

#### Executive Compensation Philosophy & Practices
Our executive compensation program is based on a philosophy that aligns the interests of our executives and stockholders. The following are key objectives of our compensation philosophy, which are used to guide the Compensation Committee in making compensation decisions. These objectives are evaluated to confirm the appropriateness of each objective in light of the overall corporate strategy and market practices.

• Attract, motivate and retain highly experienced executives who are vital to our short- and long-term success, profitability and growth;

• Align the focus of our executives with the interests of our stockholders by rewarding executives for the achievement of strategic goals that successfully drive our strategy, operations and business performance and, thereby, enhance stockholder value;

• Differentiate pay and rewards based on criticality of role and actual individual and company financial performance while remaining fair and equitable; and

• Promote thoughtful decision-making while discouraging unnecessary and excessive risk-taking.

In support of this philosophy, the Compensation Committee:

• Reviews and approves corporate goals and objectives for our CEO;

• Evaluates the performance of our CEO in light of such goals and objectives and approves the annual base salary, annual incentive, LTIs and other benefits provided to the CEO and other executive officers;

• Reviews and recommends to the full Board, or approves, new executive compensation programs, including LTI compensation programs;

• Periodically reviews the operation of our executive compensation programs as well as the administration of such programs to determine whether they are achieving their intended purpose(s);

• Requires our executives to establish and maintain significant stock ownership in the Company;

• Engages an independent compensation consultant to solely advise the Compensation Committee as to the competitiveness of our program and incentives being provided to our CEO and the other executives; and

• Places a significant portion of each executive's compensation at risk, contingent upon meeting measurable and meaningful performance goals.

#### Most Recent Say-on-Pay Voting Results
At our 2022 Annual Meeting of Stockholders, the stockholders approved, on a non-binding advisory basis, holding a non-binding advisory vote to approve the executive compensation of the NEOs on an annual basis (the "Say-on-Pay vote"). Our most recent Say-on-Pay vote was held at our 2025 Annual Meeting of Stockholders, which received 95.14% stockholder support. We believe this strong Say-on-Pay vote outcome shows support for the program and no changes have been made to the current program design as a result of the most recent Say-on-Pay vote. As discussed in this proxy statement, we will be conducting a non-binding Say-on-Pay vote at our 2026 Annual Meeting.

Role of Compensation Committee, Management and Compensation Consultant in Compensation Decisions

Pursuant to its charter, the Compensation Committee is responsible for overseeing our executive compensation program, developing and reviewing our executive compensation philosophy, and recommending to the full Board, or approving, decisions regarding executive compensation.

The Compensation Committee is ultimately responsible for making the compensation decisions with respect to our CEO and other NEOs and creating appropriate programs for them. The Compensation Committee seeks and considers input from senior management and an independent compensation consultant in connection with its duties. In 2025, the Compensation Committee engaged FW Cook as a consultant on executive compensation matters.

FW Cook's engagement includes reviewing and advising on executive compensation matters principally related to the CEO, the executive officers, our senior executives and outside directors. For 2025, FW Cook assisted the Compensation Committee by:

• Recommending a comparator group for benchmarking purposes;

• Providing comparator group data on compensation levels and design for our executive officers and outside directors;

• Reviewing the Company's compensation policies and practices and providing assessments as to whether such policies and practices are reasonably likely to have a material adverse effect on the Company; and

• Providing insight into broader market practices, executive compensation trends and regulatory developments and management compensation proposals.

FW Cook performs services solely on behalf of the Compensation Committee and does not provide any other services to us. The Compensation Committee assessed the independence of FW Cook and concluded that no conflicts of interest exist that would prevent FW Cook from independently representing the Compensation Committee.

Executive management regularly participates in the compensation decision-making process in the following specific respects:

• The CEO reports to the Compensation Committee his performance evaluation of our senior executives, including the NEOs (other than himself). Together with the EVP, Chief Human Resources Officer, the CEO recommends compensation decisions for these individuals, including base salary levels, the mix of incentive awards and performance objectives; and

• The CEO develops recommended performance objectives and targets for our incentive compensation programs.

Overview of 2025 Target Compensation Mix

The Compensation Committee annually reviews the CEO's and other NEOs' compensation. Through this process, the Compensation Committee evaluates all elements of target total compensation against a pre-determined group of companies (as described below in the section titled "Market Analysis and Benchmarking"). As noted in the following section, there is a significant emphasis on performance-based components of compensation. For additional detail on each compensation component, please see the sections below titled "2025 Executive Compensation Program—Base Salary," "2025 Executive Compensation Program—Annual Incentive Plan" and "2025 Executive Compensation Program—Long-Term Incentive Plan."

------

##### [**Table of Contents**](#toc)

#### Target Compensation Mix
There is a significant emphasis on the elements that comprise performance-based pay (annual and long-term incentive awards). As illustrated in the following charts, a significant percentage of our CEO's and all other NEOs' 2025 target total compensation (*i.e.*, target annual incentive, RSUs and PSUs) is linked to Company performance and aligned with the interests of our stockholders and considered "at-risk:" 93% for the CEO and 83% for our other NEOs.

Key Executive Compensation Components

The key components of our executive compensation program for NEOs are base salary, annual incentive, employee benefits (health, welfare, retirement and perquisites) and LTI awards, which consist of time-vested RSUs and PSUs, which are subject to a three-year performance period.

These elements are illustrated in detail below:

---

Market Analysis and Benchmarking

As described below, we use various tools and methods, including benchmarking, to evaluate whether each NEO's level of pay is appropriate. For 2025, the benchmarking process for all of our NEOs is described below.

#### Benchmarking
The Compensation Committee benchmarks against the median for each pay component (*i.e.*, base salary, target annual incentive and target LTI grants) and total compensation to guide our compensation objectives. We utilize the median as a point of reference and not necessarily the definitive compensation level. Consequently, our NEOs' compensation may be positioned at a level less than or greater than the median based on time in position, experience and competitive pay objectives, as well as other factors.

*Comparator Group* 

The Compensation Committee, with input from FW Cook and management, annually approves a public-company comparator group (the "Custom Comparator Group") to be used in reviewing and benchmarking various pay components in addition to the use of technology industry and general industry data.

The selection of the Custom Comparator Group begins with an initial list of potential organizations and is then filtered using various selection criteria to determine our final list of comparator companies. The following outlines the process the Compensation Committee used in selecting the Custom Comparator Group for benchmarking executive compensation.

![LOGO](g42958g67n89.jpg)

Based on the above methodology, the evaluation resulted in no year-over-year changes to our Custom Comparator Group.

##### [**Table of Contents**](#toc)
2025 Executive Compensation Program

#### Base Salary
Each NEO receives an annual base salary as compensation for services rendered in the NEO's position during the year. The Compensation Committee annually evaluates the performance of the CEO and determines his base salary in light of his goals and objectives, individual performance and competitive market data. The Compensation Committee also, at least annually, reviews each other NEO's base salary based on a recommendation from the CEO, with input from our EVP, Chief Human Resources Officer, and adjusts the NEO's base salary when appropriate. In general, the CEO recommends a base salary increase for the other NEOs when supported by additional responsibilities, strong individual performance or changes in competitive market data.

In February 2025, as part of the annual compensation review process, Mr. Cello received a base salary increase to reflect strong performance and to better align his pay with executives holding comparable positions in the Custom Comparator Group. Mr. Cartwright's base salary remained unchanged from 2024. Our other NEOs' 2025 base salaries were established in connection with the commencement of their employment with TransUnion in 2025.

The following table sets forth the NEO's 2025 annualized base salary compared to each individual's 2024 annualized base salary.

(1) Mr. Abdelsadek and Mses. Chambers and Zuiker do not have 2024 data as each commenced employment with the Company in 2025.

#### Incentive Compensation
Outside of base salary, benefits and perquisites (described below), all other compensation received by each NEO is considered "at-risk," including compensation received under our annual incentive plan and LTI plan.

*Target Setting* 

The Compensation Committee set the performance targets for our 2025 annual incentive plan and LTI plan in early 2025. The Compensation Committee believes that the performance targets it established were appropriately challenging, while providing meaningful motivational value to our NEOs. The performance targets required the Company to generate significant performance while effectively managing various macroeconomic factors during 2025.

The Compensation Committee considered the following factors when establishing the performance targets, including the related threshold and maximum target levels:

• corporate strategy;

• annual and long-term operating plans;

• performance history;

• macroeconomic environment;

------

##### [**Table of Contents**](#toc)
• input from FW Cook and management; and

• difficulty of the performance targets in light of the above factors.

#### Annual Incentive Plan
The annual incentive plan is designed to motivate and reward our NEOs based on financial and individual performance. Financial targets are approved by the Compensation Committee at the beginning of the performance period with individual and other qualitative goals designed to successfully drive our operations and business results and to achieve our overall corporate strategy. Each NEO's annual incentive is determined by multiplying the applicable NEO's target annual incentive percentage by the NEO's eligible base salary and then multiplying this result by the percentage achievement with respect to the applicable financial and individual goals, provided the threshold level of performance is achieved.

*Target Levels* 

Each NEO has a target annual incentive expressed as a percentage of their eligible base salary. The target is determined by the Compensation Committee after consideration of several factors, including the NEO's duties and responsibilities and competitive market data. Mr. Cartwright received an increase to his 2025 target annual bonus from 150% to 175% of his base salary in order to better align his pay with other CEOs in the Custom Comparator Group. Mr. Cello's 2025 target annual bonus was unchanged from 2024. Our other NEOs' 2025 target annual bonuses were established in connection with the commencement of their employment with TransUnion in 2025.

*Financial and Individual Objectives, Targets and Potential Payouts* 

The following table defines the various financial and individual objectives applicable for the 2025 annual incentive plan. The actual payout ranges between 0% and 200% of target for each objective depending on actual performance. The objectives of Defined Consolidated Adjusted EBITDA, Defined Consolidated Revenue and Defined Adjusted Diluted Earnings per Share (each defined below) are to incentivize our NEOs to drive the achievement of overall Company financial performance. Strategic Individual Objectives consist of quantitative and qualitative metrics tailored to each NEO, which are designed to drive key business priorities and incentivize the delivery of significant strategic progress. Additionally, these goals are designed to provide NEOs with the

------

##### [**Table of Contents**](#toc)
opportunity to achieve above target payouts only upon robust performance. In 2025, the Strategic Individual Objectives were subject to a downward modifier based on the Company's Operational Standards and Risk Management Objectives (as defined below).

It also provides actual 2025 results and payouts under the 2025 annual incentive plan as a percentage of target. For each financial objective the NEO receives a 50% payout at threshold performance, a 100% payout at target performance and a 200% payout at maximum performance. The payout for performance between percentages is interpolated on a straight-line basis and performance below threshold results in a 0% payout for that financial objective.

*2025 Annual Incentive Payouts* 

The following table summarizes each NEO's 2025 annual incentive plan objectives described above, including the applicable weighting, payout as a percentage of target and payout as a dollar amount. The weightings for each NEO are determined based on the NEO's role, duties and responsibilities and are designed to strengthen the link between pay and performance. Payments based on the 2025 annual incentive plan were 154.0% of target.

For the Strategic Individual Objectives, the Board (for the CEO) and the CEO (for the remaining NEOs) evaluated each of the NEOs in conjunction with such NEO's self-evaluation, with the Compensation Committee approving the final performance. In 2025, all of our NEOs, including our CEO, earned a 105% payout on their Strategic Individual Objectives. Mr. Cartwright delivered financial results that exceeded expectations each quarter, while accelerating TransUnion's pace of innovation and enhancing its technology and operating platforms. Mr. Cello demonstrated strong leadership by enhancing finance operations through both technology and talent development, strengthening the global capability centers for ongoing transformation, and driving meaningful process simplification and efficiency improvements. Since joining TransUnion in March 2025, Mr. Abdelsadek has materially advanced the product management initiative by strengthening alignment between product solutions and the broader organization and driving positive momentum. Since joining TransUnion in February 2025, Ms. Chambers has effectively delivered a clear strategic direction for global operations, aligning the organization with our technology transformation and establishing a scalable, client and consumer centric roadmap. Since joining TransUnion in June 2025, Ms. Zuiker has demonstrated strong leadership by elevating human resources and communications from tactical execution to a strategic enterprise enabler, strengthening incentives, workforce strategy, and the operating model to support scalable global growth. The Compensation Committee also considered progress against various applicable human capital goals as part of its holistic

evaluation of each NEO. The Company achieved its Operational Standards and Risk Management Objectives; therefore, no downward modification was made to any of the NEOs' final Strategic Individual Objectives.

*2026 Annual Incentive Plan* 

In 2026, the weightings of the metrics in the annual incentive plan for our NEOs will be as follows: Defined Consolidated Adjusted EBITDA – 35%, Defined Consolidated Revenue – 35%, Defined Adjusted Diluted Earnings per Share – 20%, and Strategic Individual Objectives – 10%. The Compensation Committee determined to remove the Operational Standards and Risk Management Objectives as a modifier in our 2026 annual incentive plan. The Compensation Committee and the Company remain committed to strong operational risk management and the Company has embedded all of the applicable operational risk management metrics into its day-to-day operations or into the NEOs' Strategic Individual Objectives. The Compensation Committee has the discretion under the 2026 annual incentive program to make adjustments to performance metrics and/or results as it determines to be appropriate or necessary in order to reflect the impact of mergers, acquisitions and dispositions, corporate allocations and/or transfers of revenue and/or expenses from one segment of our business to another.

#### Long-Term Incentive Plan
*2025 Annual LTI Grants* 

Our NEOs receive annual LTI grants, which are linked directly to the creation of stockholder value over a multi-year term. In 2025, 80% of the target total compensation opportunity provided to our CEO and 65% of the target total compensation opportunity provided to all other NEOs was equity-based and directly correlated to the Compensation Committee's view that there should be a strong connection between an NEO's rewards and stockholder value creation.

As noted previously, 50% of the 2025 target LTI grant value was delivered in the form of time-vested RSUs that vest ratably over a 42-month period where 33% vests on each of August 28, 2026 and August 28, 2027, and 34% vests on August 28, 2028. The remaining 50% of the 2025 target LTI grant value was delivered in the form of PSUs that vest following a three-year performance period starting January 1, 2025 and ending December 31, 2027. When dividends are paid on our common stock, unvested RSUs accrue dividend equivalents that are paid out in cash or, in the sole discretion of our Compensation Committee, in shares of our common stock, based on the number of shares that vest. Similarly, for PSUs, dividend equivalents accrue during the performance period and are paid out in cash or, in the sole discretion of our Compensation Committee, in shares of our common stock, based on the number of shares that vest as a result of actual Company performance.

The PSU grants made in 2025 have the following three performance components and weightings with the actual payout ranging between 0% and 200% of target for each performance component depending on actual Company performance:

---

| | |
|:---|:---|
| **Performance Component**  | **Weighting** |
|  Cumulative Adjusted Diluted Earnings per Share<sup>(1)</sup> | 30% |
|  Cumulative Revenue<sup>(1)</sup> | 20% |
|  Relative TSR against the companies in the Commercial and Professional Services industry classification within the Russell 3000 Index (the "Relative TSR Peer Group") | 50% |

---

(1) Cumulative Adjusted Diluted Earnings per Share is calculated using the definition of Adjusted Diluted Earnings per Share disclosed in our 2025 Annual Report on Form 10-K, adjusted to be on an organic, constant currency basis. Cumulative Revenue is calculated based on revenue reported in our 2025 Annual Report on Form 10-K, adjusted to be on an organic, constant currency basis.

Additionally, if our actual Total Stockholder Return ("TSR") during the performance period is negative, then the maximum payout for the Relative TSR performance component is 100%, regardless of actual performance against the Relative TSR Peer Group.

------

##### [**Table of Contents**](#toc)
The Compensation Committee sets our financial performance targets for the Cumulative Adjusted Diluted Earnings per Share and Cumulative Revenue components taking into consideration our long-term strategic plan. We do not publicly disclose specific financial performance targets on a prospective basis. Prospectively disclosing these specific targets would provide competitors and others with insights into our confidential planning process and strategies and potentially harm us competitively. We design our financial performance targets to be challenging. There is a risk we will not achieve threshold or target performance resulting in either no shares or shares awarded below target.

The Cumulative Adjusted Diluted Earnings per Share and Cumulative Revenue performance components applicable to our PSUs granted in 2025 differ from the Defined Adjusted Diluted Earnings per Share and Defined Consolidated Revenue financial components in our 2025 annual incentive plan. Each are independent financial components intended to drive different behavior. The performance targets for the annual incentive financial components are based on our annual internal operating targets and designed to incentivize our annual performance, while the performance targets for the PSU components are based on our long-term strategic plan and designed to incentivize long-term performance.

To determine the 2025 target LTI grant value for each NEO, the Compensation Committee considered target total compensation data from our Custom Comparator Group for comparable executive positions, the strategic direction of the Company and the NEO's scope of authority and responsibility.

The target number of restricted stock units (both RSUs and PSUs) granted to each NEO was determined by dividing the target grant value by the closing stock price on the date of grant and rounding down to the nearest whole share. The aggregate grant date fair values of these RSUs and PSUs are reported in the "Summary Compensation Table—2025" calculated in accordance with FASB ASC Topic 718.

The table below reflects the 2025 target annual LTI grant value for each NEO with respect to the annual LTI grant made on February 28, 2025 for Messrs. Cartwright and Cello and Ms. Chambers, and September 2, 2025 for Mr. Abdelsadek and Ms. Zuiker, which were pro-rated based on their respective employment start dates.

*2023 PSU Performance* 

In February 2026, the Compensation Committee certified the results for the 2023 PSUs, which vested on February 28, 2026. Vesting of the 2023 PSUs was based on Cumulative Adjusted EBITDA, Cumulative Revenue and our Relative TSR against the Relative TSR Peer Group.

The chart below details the applicable performance measures, weightings, targets and the certified performance achievement as a percentage of target. The payout for performance between percentages is interpolated on a straight-line basis and performance below threshold results in a 0% payout for that performance measure. The Compensation Committee did not exercise any discretion to adjust the final performance achievement for the 2023 PSUs.

Sign-On Equity Grants

As described above, a primary goal of our executive compensation program is to attract, motivate and retain highly experienced executives who are vital to our short- and long-term success, profitability and growth. The CEO and Compensation Committee extensively review talent retention on an on-going basis. In 2025, we made sign-on equity grants to Mr. Abdelsadek and Mses. Chambers and Zuiker in connection with the commencement of their employment with TransUnion.

On November 15, 2024, the Compensation Committee approved a sign-on equity grant of time-vesting RSUs to Ms. Chambers with a dollar-denominated value of $4,700,000, which was granted on March 3, 2025. The RSUs will vest over a 36-month period, 31% of which vested on September 3, 2025, 36% of which vested on March 3, 2026, 25% of which will vest on March 3, 2027, and 8% of which will vest on March 3, 2028, subject to Ms. Chambers' continued service as of the applicable vesting date.

On December 4, 2024, the Compensation Committee approved a sign-on equity grant of time-vesting RSUs to Mr. Abdelsadek with a dollar-denominated value of $5,811,000, which was granted on April 1, 2025. The grant is comprised of RSUs that will vest over a 36-month period, 34% of which vested on October 1, 2025, 32% of which will vest on April 1, 2026, 31% of which will vest on April 1, 2027, and 3% of which will vest on April 1, 2028, subject to Mr. Abdelsadek's continued service as of the applicable vesting date.

On June 4, 2025, the Compensation Committee approved a sign-on equity grant of time-vesting RSUs to Ms. Zuiker with a dollar-denominated value of $3,500,000, which was granted on July 1, 2025. The RSUs will vest over a 36-month period, 40% of which will vest on July 1, 2026, 30% of which will vest on July 1, 2027, and 30% of which will vest on July 1, 2028, subject to Ms. Zuiker's continued service as of the applicable vesting date.

2026 Annual LTI Grants

Consistent with the 2025 annual LTI grants, 50% of the target 2026 LTI grant value will be delivered in the form of PSUs, as described above, and the remaining 50% of the 2026 annual LTI grant will continue to be delivered in time-vested RSUs that vest ratably over a 42-month period where 33% will vest on each of August 27, 2027 and August 27, 2028, and 34% will vest on August 27, 2029. The PSUs granted in 2026 will be eligible to vest based on substantially the same metrics and weightings as applied to the 2025 PSUs over a three-year performance period, commencing on January 1, 2026 and ending on December 31, 2028.

#### Stock Ownership Requirements
The Compensation Committee maintains a formal stock ownership policy requiring all executives (defined as the CEO and his direct reports) to hold TransUnion common stock, including unvested RSUs, in an amount equal to six times annual base salary for the CEO and three times annual base salary for all other executives. To attain the requisite multiples, the executive must retain 75% of the after-tax value of the executive's shares received pursuant to any long-term incentive grant made after January 1, 2016 until such multiple is achieved. Executives aged 60 or older are subject to a reduced ownership requirement equal to 50% of the applicable amount.

All NEOs have satisfied their applicable stock ownership requirements as of December 31, 2025.

#### Prohibited Transactions; Hedging and Pledging
Our Insider Trading Policy limits the timing and types of transactions in TransUnion securities by Company directors, employees and officers (including our NEOs), and any member of such person's immediate family sharing the same household, any corporations or other business entities they control or manage, and any trusts of which they are the trustee or otherwise have investment control over.

------

#### **Table of Contents**
Subject to certain specified exceptions, among other restrictions,

our Insider Trading Policy:

• allows all executive officers, directors and certain designated employees to trade TransUnion securities only during open window periods and only after they have pre-cleared transactions with the Executive Vice President, Chief Legal Officer (or her designee);

• prohibits the short-selling of TransUnion securities or "selling against the box" (failing to deliver sold securities); and

• prohibits transactions in puts, calls or other derivatives on TransUnion securities on an exchange or in any other organized market, as well as any other derivative or hedging transactions on TransUnion securities.

Transactions made pursuant to approved 10b5-1 plans, certain stock option exercises and purchases through our 2015 Employee Stock Purchase Plan (as amended from time to time), are examples of the types of transactions that may be permissible during blackout periods, in accordance with our Insider Trading Policy.

Our Insider Trading Policy also prohibits holding TransUnion securities in a margin account or pledging TransUnion securities as collateral for a loan unless approval is received from the Executive Vice President, Chief Financial Officer and Executive Vice President, Chief Legal Officer (or their respective designees), which approval is in their sole discretion.

#### Clawback Policy
The Board maintains the TransUnion Policy for Recovery of Erroneously Awarded Compensation (the "Clawback Policy") in accordance with the rules issued by the SEC and NYSE that took effect in 2023. Pursuant to the Clawback Policy, in the event that the Company is required to prepare an accounting restatement to correct the Company's material noncompliance with any financial reporting requirement under securities laws, the Company must recover any incentive-based compensation received by any of our current or former executive officers during the three completed fiscal years immediately preceding the date of the applicable accounting restatement to the extent the amount of such incentive-based compensation received by any such executive officer exceeds the amount that would have been received had such incentive-based compensation been determined based on the restated financial reporting measure.

#### Equity Award Timing Policies and Practices
We do not currently grant (and do not currently have any outstanding) stock options, stock appreciation rights or any similar awards with "option-like" features. Although we do not have a formal policy with respect to the timing of our equity award grants, the Compensation Committee generally grants equity awards on a consistent annual schedule, and we do not take material non-public information of the Company into account when determining the timing and terms of such awards. In addition, we do not grant equity awards in anticipation of the release of material non-public information, and we do not time the release of material non-public information for the purpose of affecting the value of executive compensation.

#### Executive Benefits and Perquisites
The NEOs receive benefits that are part of a competitive total compensation package necessary to attract and retain executive talent, and are generally identical to those we provide to other U.S.-based employees. These benefits include medical, dental, vision, life and disability insurance. In addition, we offer a qualified retirement plan (described below) and, for the NEOs, a nonqualified supplemental retirement plan (described below). NEOs are also eligible to participate in an annual physical program and may receive reimbursement for financial planning and tax services up to the maximum amount of $15,000 for the CEO and $12,000 for the other NEOs.

------

#### **Table of Contents**

#### Retirement Plans
We maintain the TransUnion 401(k) & Savings Plan (the "401(k) Plan"), which is a broad-based 401(k) savings and retirement plan in which all U.S. based employees, including the NEOs, may participate. Generally, we match employees' eligible contributions up to a certain amount and also may make a non-elective Company contribution. The Internal Revenue Code of 1986, as amended (the "Code") places certain limits on the amount of contributions that may be made by and on behalf of employees to the 401(k) Plan. Therefore, to allow for contributions beyond the limits set under the Code, we also maintain the nonqualified Retirement and 401(k) Supplemental Plan (the "Supplemental Plan") for U.S. based employees. In general, under the Supplemental Plan, each NEO may defer all or some portion of the NEO's cash compensation that the NEO was not otherwise permitted to defer under the 401(k) Plan due to limitations under the Code in order to provide additional retirement savings. Matching contributions to the Supplemental Plan are made on a discretionary basis using the same matching formula under the 401(k) Plan. Additionally, we may make a discretionary non-elective contribution on behalf of the NEOs to the Supplemental Plan at the end of the year based on a similar contribution to the 401(k) Plan.

#### CEO Employment Agreement
Upon his promotion to CEO, we entered into an employment agreement with Mr. Cartwright (the "Cartwright Employment Agreement"), which is summarized under "Executive Compensation—Payments upon Termination and Change in Control—2025" and the accompanying narrative.

We have entered into a Severance and Restrictive Covenant Agreement (the "Severance Agreement") with each of the other NEOs (other than Mr. Cartwright). The Severance Agreements are designed to maximize retention and are summarized under "Executive Compensation—Payments upon Termination and Change in Control—2025" and the accompanying narrative.

#### Use of Tally Sheets
In 2025, the Compensation Committee reviewed compensation summaries for each executive officer, including the NEOs. These summaries outline each component of pay and amounts paid in certain termination and change in control scenarios. Changes to our NEOs' compensation are not based off this information; however, the Compensation Committee uses this information to confirm that pay objectives continue to be aligned with the long-term interests of our stockholders.

#### Federal Income Tax Considerations
Section 162(m) of the Code limits the deductibility of compensation in excess of $1 million paid to certain NEOs in any calendar year. Additionally, under the tax rules in effect before 2018, compensation that qualified as "performance-based" under Section 162(m) was deductible without regard to this $1 million limit. However, the 2017 Tax Cuts and Jobs Act (the "Tax Act") eliminated this performance-based compensation exception effective January 1, 2018, subject to a special rule that "grandfathers" certain awards and arrangements that were in effect on or before November 2, 2017. As a result, compensation that the Compensation Committee structured to qualify as performance-based compensation under Section 162(m) of the Code that is paid on or after January 1, 2018 may not be fully deductible, depending on the application of the special grandfather rules.

While the Tax Act limits the deductibility of compensation paid to the NEOs, such limitations will not have a material impact on our executive compensation program. Our Compensation Committee may, among other things, determine that failing to meet its objectives to attract, retain and motivate senior executives creates more risk for the Company than the financial impact of losing the tax deduction. Our Compensation Committee will continue to structure our compensation program in the best long-term interests of our stockholders, with deductibility of compensation being one of a variety of considerations taken into account.

(1) The base salary rate for Mr. Cartwright remained the same for 2025 from 2024; however, due to a lower number of working days in 2025 compared to 2024, the amount reported in this column for 2025 for Mr. Cartwright is lower than the amounts reported in 2024.

(2) Amounts in this column represent a cash sign-on bonus of $612,800 paid to Mr. Abdelsadek and a cash sign-on bonus of $600,000 paid to Ms. Chambers in connection with the commencement of their respective employment with TransUnion.

(3) The amounts shown in this column represent the aggregate grant date fair value of RSUs and PSUs granted to the NEOs calculated in accordance with FASB ASC Topic 718. For 2025 RSUs, assumptions used in the calculation of these amounts are included in Note 16, "Stock-Based Compensation," of the consolidated financial statements in our 2025 Annual Report on Form 10-K. For PSUs based on Cumulative Adjusted EBITDA (for PSUs granted in 2023) or Cumulative Adjusted Diluted Earnings per Share (for PSUs granted in 2024 and 2025) and Cumulative Revenue, the amounts are based on target performance, which is the probable outcome under FASB ASC Topic 718 as of the grant date, and our stock price as of the grant date. For PSUs based on Relative TSR, the amounts are based on the fair value as of the grant date as determined using a risk-neutral Monte Carlo model. For the 2025 PSUs granted in February 2025 and September 2025, assumptions used in the calculation of grant date fair value for the PSUs based on Relative TSR include: (i) a remaining term of 2.84 and 2.33 years, respectively; (ii) a risk-free rate of 3.95% and 3.62%, respectively; (iii) an expected dividend yield of 0% for both grants; (iv) the historical stock price volatility for the Company and our peers ranging between 15.89% and 123.09% for both grants; and (v) the Company's dividend adjusted stock price on the date of grant of $92.55 and $86.80, respectively. The table below illustrates the grant date fair value of the PSUs based on Cumulative Adjusted EBITDA (for PSUs granted in 2023) or Cumulative Adjusted Diluted Earnings per Share (for PSUs granted in 2024 and 2025) and Cumulative Revenue (for PSUs granted in 2023, 2024 and 2025) assuming a maximum performance of 200%, and the grant date fair value of the PSUs based on Relative TSR at a target performance of 100% for each NEO.

(1) Reflects threshold, target and maximum payment opportunities for the 12 months ended December 31, 2025 under our 2025 annual incentive plan. The threshold amount reflects a 50% payout of the target incentive opportunity, which is payable only if the applicable financial and/or individual performance goals are achieved at threshold levels. The target amount reflects a 100% payout of the target incentive opportunity if both financial and individual performance are at target levels. The maximum amount reflects a 200% payout of the target incentive opportunity, if both financial and individual performance are at maximum levels. The actual amounts paid in March 2026 under our 2025 annual incentive plan are disclosed in the "2025 Summary Compensation Table" under the "Non–Equity Incentive Plan Compensation" column.

(2) Reflects PSUs granted during 2025 under our Second Amended 2015 Plan. When dividends are paid on our common stock, PSUs accrue dividend equivalents during the performance period that are paid out in cash or, in the sole discretion of our Compensation Committee, in shares of our common stock, based on the number of shares that vest as a result of actual Company performance. The performance components and vesting provisions for the PSUs are described above in the section titled "2025 Executive Compensation Program—Long-Term Incentive Plan."

(3) Reflects RSUs granted during 2025 under our Second Amended 2015 Plan. When dividends are paid on our common stock, unvested RSUs accrue dividend equivalents that are paid out in cash or, in the sole discretion of our Compensation Committee, in shares of our common stock, based on the number of shares that vest. The vesting provisions for the RSUs are described above in the section titled "2025 Executive Compensation Program—Long-Term Incentive Plan."

(4) The amounts shown in this column represent the aggregate grant date fair value calculated in accordance with FASB ASC Topic 718. For 2025 RSUs, assumptions used in the calculation of these amounts are included in Note 16, "Stock-Based Compensation," of the consolidated financial statements in our 2025 Annual Report on Form 10-K. For PSUs based on Cumulative Adjusted Diluted Earnings per Share and Cumulative Revenue, the amounts are based on target performance, which is the probable outcome under FASB ASC Topic 718 as of the grant date, and our stock price as of the grant date. For PSUs based on Relative TSR, the amounts are based on the fair value as of the grant date as determined using a risk-neutral Monte Carlo model. We provide information regarding the assumptions used to calculate the value of all PSU and RSU awards made to our NEOs in footnote (1) to the Summary Compensation Table above.

(3) Amounts reported in this column do not constitute above-market or preferential earnings and, therefore, are not reported in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column of the Summary Compensation Table for 2025. Each NEO self-directs the investment of the Supplemental Plan account balance into one or more of the available investment funds described below.

(4) The aggregate balance includes amounts previously reported as compensation for our NEOs in the Summary Compensation Table for prior years for each NEO. These amounts include the following for our other NEOs: Mr. Cartwright- $799,395 and Mr. Cello- $327,491. Mr. Abdelsadek and Mses. Chambers and Zuiker did not participate in the non-qualified deferred compensation plan for 2025.

#### Nonqualified Deferred Compensation Plan
The Supplemental Plan is a nonqualified tax deferred compensation program for a limited number of U.S.-based executives, including the NEOs. The Supplemental Plan provides a favorable tax vehicle for deferring cash compensation (*i.e.*, salary and annual incentive payments). Under the terms of the Supplemental Plan, participants are able to defer up to 100% of cash compensation received. Deferred amounts are self-directed into one or more of the available investment funds described below and are credited with gains or losses of the various funds selected by the participant. The Supplemental Plan does not offer any above-market rate of return. Upon termination of employment, deferred amounts are paid, at the participant's election, in a lump sum or annual installments over a period of either five or ten years. Participants are not permitted to take loans under the terms of the Supplemental Plan. On a discretionary basis, we contribute a match equal to 100% of the first 3% and 50% on the next 2% of the participant's contributions, which mirrors the 401(k) Plan. The table below lists the available investment options under the Supplemental Plan and their annual rate of return for the 2025 calendar year.

Payments upon Termination and Change in Control—2025

#### Cartwright Employment Agreement
Pursuant to the Cartwright Employment Agreement, upon an involuntary termination by the Company without Cause (as defined in the Cartwright Employment Agreement), termination following non-renewal or voluntary termination for good reason by Mr. Cartwright, Mr. Cartwright is entitled to certain severance payments and benefits, contingent on his execution and non-revocation of a general release of claims. Details of the payments under the Cartwright Employment Agreement upon various separation scenarios are described below.

"Good reason" is defined in the Cartwright Employment Agreement as the occurrence or non-occurrence of any of the following events, without written consent:

• a material reduction in position, overall responsibilities, level of authority, title or level of reporting;

• a material reduction in base salary compensation and annual incentive compensation opportunity, measured in the aggregate, which is not the result of a uniformly applied adjustment across all similarly-situated employees;

• a change in location of employment by more than 50 miles from the then-current location; or

• a material breach of any material covenant, provision or term of the Cartwright Employment Agreement.

The Cartwright Employment Agreement also includes certain restrictive covenants and confidentiality provisions intended to protect our interests, including a non-compete clause for 12 months following termination, a customer non-solicitation clause for 12 months following termination and an employee non-solicitation clause for twenty-four months following termination. The table below outlines the payments under the Cartwright Employment Agreement upon various separation scenarios.

#### NEO Severance Agreements
We have also entered into Severance Agreements with each of the other NEOs other than Mr. Cartwright. The Severance Agreement for each NEO contains similar provisions, including certain severance payments, contingent upon executing a general release of claims, upon an involuntary termination without cause or voluntary termination for good reason. Details of the payments under each NEO's Severance Agreement upon various separation scenarios are described below.

"Good reason" is defined in the Severance Agreements as:

• a material reduction in position, overall responsibilities, level of authority, title or level of reporting;

• a material reduction in base salary compensation and annual incentive compensation opportunity, measured in the aggregate, which is not the result of a uniformly applied adjustment across all similarly-situated employees; or

• a change in location of employment by more than 50 miles from the then-current location.

Each Severance Agreement also includes certain restrictive covenants and confidentiality provisions intended to protect our interests, including a non-compete clause for 12 months following termination, a customer non-solicitation clause for 12 months following termination and an employee non-solicitation clause for 12 months following termination. The tables below outline the payments under each NEO's Severance Agreement upon various separation scenarios.

#### LTI Grants
LTI grants to our NEOs are governed by the terms and conditions of the underlying grant agreements and applicable plan. RSUs and PSUs granted prior to May 2, 2024 were granted under our Amended and Restated 2015 Omnibus Incentive Plan (the "First Amended 2015 Plan") and RSUs and PSUs granted on or after May 2, 2024 were granted under our Second Amended 2015 Plan. The tables below outline the vesting treatment of LTI grants upon various scenarios under the First Amended 2015 Plan and Second Amended 2015 Plan.

| | | |
|:---|:---|:---|
| Scenario | Vesting Treatment | Definitions |
| Death or<br>Disability | All unvested RSUs and PSUs immediately vest upon death or *disability* assuming target performance for the PSUs. | *Disability* has the meaning in any employment, consulting or similar agreement or, in the absence of any such definition or agreement, it is a condition entitling the employee to receive benefits under a long-term disability plan of the Company, or, in the absence of such a plan, the complete and permanent inability of the employee by reason of illness or accident to perform his or her duties. |
| Voluntary or<br>Involuntary Termination | All unvested RSUs and PSUs forfeit, unless the employee is *retirement eligible*. If the employee is *retirement eligible*, subject to the holder's execution of a general release of claims in a form prescribed by the Company, (i) the RSUs granted in a calendar year prior to the calendar year of retirement vest pro rata based on the number of months actively employed during the vesting period and (ii) PSUs granted in a calendar year prior to the calendar year of retirement vest pro rata, subject to actual Company performance during the full performance period, and based on the number of months the employee provides services to us during the performance period.<br>Under the terms of the Cartwright Employment Agreement, if Mr. Cartwright is involuntarily terminated without cause, terminates following a non-renewal of the agreement by the Company or voluntarily resigns for good reason, subject to his execution of a release of claims and continued compliance with restrictive covenants, any outstanding RSUs or PSUs granted on or after January 1, 2019 will vest pro rata based on the number of full and partial months he was actively employed during either the vesting period (RSUs) or performance period (PSUs). All PSUs are subject to actual Company performance during the full performance period. | &nbsp;&nbsp;&nbsp;&nbsp; To qualify as *retirement eligible*, an employee must terminate employment (for any reason other than disability, death or for cause) at a time when:<br>• the employee is age 55 (or older),<br>• the sum of the employee's age plus completed years of service is at least 65,<br>• the employee has completed at least 5 years of service with the Company,<br>• the employee does not have an offer for and has not accepted employment with any other for-profit business on financial terms and conditions substantially similar to those provided by the Company, and<br>• the employee provided at least 60 days' written notice of the employee's intent to retire.<br>As of December 31, 2025, only Mr. Cartwright was retirement eligible. |
| Qualifying<br>Termination<br>following a<br>Change in<br>Control | All RSUs and PSUs fully vest only if there is a *qualifying termination* within two years following the *change in control* (unless the RSUs and PSUs are not assumed in the transaction).<br>The PSUs will vest and be settled based on our actual performance for the Relative TSR performance component as of the date of the change in control and target performance for the Cumulative Adjusted EBITDA (for PSUs granted in 2023) or Cumulative Adjusted Diluted Earnings per Share (for PSUs granted in 2024 and 2025) and Cumulative Revenue (for PSUs granted in 2023, 2024 and 2025) performance components. | *Qualifying termination* includes an involuntary termination for any reason other than death, disability or cause or termination for good reason (as defined in the Cartwright Employment Agreement for Mr. Cartwright or the Severance Agreement for the other NEOs).<br>C*hange in control* is defined as (1) the acquisition by any person of more than 50% of Company common stock; (2) during any period of 12 months, individuals who, at the beginning of such period, constitute the Board cease for any reason to constitute at least a majority of the Board; or (3) the sale, transfer or other disposition of all or substantially all of our assets. |

##### [**Table of Contents**](#toc)
All RSUs and PSUs are subject to reduction, cancellation, forfeiture or recoupment to the extent provided in our Clawback Policy.

The following chart illustrates payments and benefits our NEOs would receive upon the occurrence of various separation scenarios, including an involuntary termination without cause or a voluntary termination for good reason, death, disability and a qualifying termination within two years following a change in control. All scenarios are assumed to occur on December 31, 2025. No incremental severance payments or equity vesting occurs upon a voluntary resignation.

(1) Severance payments for Mr. Cartwright represent payments under the terms of the Cartwright Employment Agreement. If Mr. Cartwright is involuntarily terminated without cause, terminates following a non-renewal of the agreement by the Company or voluntarily resigns for good reason, including following a change in control, then he receives a cash payment equal to two times the sum of his current base salary and target bonus, payable over 18 months in equal installments. The severance payments for the other NEOs (Messrs. Cello and Abdelsadek and Mses. Chambers and Zuiker) represent payments under the terms of their individual Severance Agreements. If the NEO is involuntarily terminated without cause or voluntarily resigns for good reason, including following a change in control, then the NEO would receive an amount equal to 1.5 times the sum of the NEO's annualized base salary and the average of such NEO's two previous years of actual bonuses under the annual incentive plan, which is paid in equal installments over 18 months. The NEOs are also eligible for a pro rata target annual incentive payment based on the number of days worked during the calendar year.

(2) Upon death or disability, all RSUs and PSUs vest. Similarly, upon a qualifying termination within two years following a change in control, all RSUs and PSUs vest. The RSU and PSU values above are based on the closing share price on December 31, 2025 ($85.75) and assume target performance for the PSUs in all cases. Under the terms of the Cartwright Employment Agreement, if Mr. Cartwright is involuntarily terminated without cause, terminated following a non-renewal of the agreement by the Company or voluntarily resigns for good reason, any outstanding RSUs or PSUs granted on or after January 1, 2019 will vest pro rata based on the number of full and partial months he was actively employed during either the vesting period (RSUs) or performance period (PSUs). All PSUs are subject to actual Company performance during the full performance period.

(3) Under the terms of the Cartwright Employment Agreement and Severance Agreements, upon an involuntary termination without cause, termination following a non-renewal of the agreement by the Company (Cartwright Employment Agreement only) or voluntary resignation for good reason, including following a change in control, each NEO receives outplacement services for a period of one year (up to a maximum value of $50,000 for Mr. Cartwright and $35,000 for all other NEOs) and a lump sum amount equal to COBRA premiums for 18 months. The amounts reflect the maximum value of the outplacement services and the value of 18 months of health, dental and vision coverage using our 2026 COBRA premium rate.

PAY RATIO DISCLOSURE

We calculated our CEO pay ratio described below in compliance with the requirements set forth in Item 402(u) of Regulation S-K. We identified the median employee using our estimated employee population as of December 31, 2025, which included 13,533 global full-time, part-time, temporary and seasonal employees employed on that date, and applied our consistently-applied compensation measure of annual base salary and annual short-term cash incentive target in effect on December 31, 2025. Nearly all of our employees receive an annual base salary (paid on an hourly, weekly, biweekly or monthly basis) and are eligible to participate in one of our short-term incentive programs (*i.e.*, company annual bonus or sales commission plan), which reasonably reflects the annual compensation of our employees. For employees outside the United States, we converted the annual base salary into United States dollars using the applicable exchange rates on December 31, 2025.

Once we identified our median employee, we then calculated the median employee's annual total compensation in the same manner as the NEOs found in the "Summary Compensation Table—2025" on page 63. Our median employee's annual total compensation was $47,057. Our President & Chief Executive Officer's annual total compensation disclosed in the Total column of the "Summary Compensation Table—2025" was $16,731,398. Accordingly, our estimated CEO to median employee pay ratio for 2025 was 356:1.

(3) The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized or received by the Company's PEO and non-PEO NEOs. These amounts reflect the Summary Compensation Table Total with certain adjustments as described in footnote 3 below.

(4) Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the PEO and the Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Negative numbers reflect a reduction in the value of the equity compensation of the PEO and Non-PEO NEOs during the relevant period. Amounts in the Exclusion of Stock Awards column are the totals from the Stock Awards column set forth in the Summary Compensation Table.

(5) The "Industry Index TSR" set forth in this table utilizes the Dow Jones U.S. Financials Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2025. The comparison assumes $100 was invested for the period starting December 31, 2020, through the end of the listed year in the Company and in the Dow Jones U.S. Financials Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.

(6) We determined Defined Consolidated Adjusted EBITDA ($ Millions) to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2025. Defined Consolidated Adjusted EBITDA is a non-GAAP measure that, as described in our CD&A, is defined as Consolidated Adjusted EBITDA as reported in our 2025 Annual Report on Form 10-K, further adjusted to eliminate the impact of foreign currency fluctuations, and to eliminate the impact of certain legal and regulatory expenses as approved by management and the Compensation Committee for annual incentive plan purposes. Other companies in our industry may calculate Consolidated Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

RISK ASSESSMENT IN COMPENSATION PROGRAMS

Our compensation programs, including our incentive compensation plans, are designed with specific features to address potential risks while rewarding employees for achieving long-term financial and strategic objectives through appropriate risk taking. The following elements are incorporated into our compensation programs to mitigate risk:

• *A Balanced Mix of Compensation Components* —The target compensation mix for our executive officers is composed of base salary, annual cash-based incentives and long-term incentive awards, representing a mix that is not overly weighted toward short-term cash incentives. For example, our RSUs and PSUs granted in 2025 have at least a three-year vesting or performance period, complementing our annual incentive.

• *Multiple Performance Factors* —Our annual incentive plan uses corporate financial metrics and individual performance, which encourages focus on the achievement of various strategic objectives for the overall benefit of the Company.

• *Capped Incentive Awards* —Annual incentive awards and PSUs are capped at 200% of target.

• *Stock Ownership* —We have stock ownership requirements for our executives aligning the interests of our executive officers with the long-term interests of stockholders.

• *Prohibited Transactions* —Our executives are prohibited from various pledging and hedging transactions.

• *Clawback Policy* —Our executive officers are subject to our Clawback Policy, which provides for the recovery of incentive-based compensation following an accounting restatement.

Based on these factors, the Compensation Committee, in consultation with management and FW Cook, concluded that our compensation programs are appropriate and do not create risks that are reasonably likely to have a material adverse effect on the Company.

PROPOSAL 4: ADVISORY VOTE ON A STOCKHOLDER PROPOSAL

REQUESTING A STOCKHOLDER RIGHT TO CALL A SPECIAL MEETING

We have been advised that John Chevedden (the "Proponent"), residing at 2215 Nelson Ave., No. 205, Redondo Beach, CA 90278, intends to present the following stockholder proposal for consideration at the Annual Meeting. The number of Company securities that the Proponent owns will be provided to stockholders promptly upon request. In accordance with federal securities laws, the stockholder proposal and supporting statement are quoted verbatim below. The Company disclaims all responsibility for the content of the proposal and the supporting statement, including any other sources referenced in the supporting statement.

#### Proposal 4 - Give Shareholders the Ability to Call for a Special Shareholder Meeting
![LOGO](g42958g18a00.jpg)

Shareholders ask our Board of Directors to take the steps necessary to amend the appropriate company governing documents to give the owners of a combined 10% of our outstanding common stock the power to call a special shareholder meeting or the owners of the lowest percentage of shareholders, as governed by state law, the power to call a special shareholder meeting. Such a special shareholder meeting can be an online shareholder meeting.

There shall be no discriminatory rule to require ownership of shares for a specific period of time in order for shares to participate in calling for a special shareholder meeting.

To guard against the TransUnion Board of Directors becoming complacent shareholders need the ability to call a special shareholder meeting to help the Board adopt new strategies when the need arises. TransUnion has been moving worse than sideways since 2020. TransUnion stock was at $102 in 2020 and at $84 in the 4th quarter of 2025.

This proposal topic received between 51% and 72% support each in 2024 at Jabil, Warner Brothers Discovery, ANSYS, Vertex Pharmaceuticals and DexCom.

A shareholder right to call for a special shareholder meeting, as called for in this proposal, can help make shareholder engagement meaningful. A shareholder right to call for an online special shareholder meeting will help ensure that the TransUnion Board and management engages with shareholders in good faith because shareholders will have a viable Plan B by calling for an online special shareholder meeting.

Any argument that a special shareholder meeting is too cumbersome has little validity. In the vast majority of cases or in most cases, once a special meeting is called for by shareholders, the issues behind calling for a special shareholder meeting are resolved.

With the widespread use of online shareholder meetings it is much easier for a company to conduct a special shareholder meeting online for important issues and the TransUnion bylaws thus need to be updated accordingly.

Please vote yes:

#### Give Shareholders the Ability to Call for a Special Shareholder Meeting Proposal 4
Board Response to Proposal 4: Advisory Vote on a Stockholder Proposal Requesting a Stockholder Right to Call a Special Meeting

We have carefully reviewed the stockholder proposal and, for the following reasons, have determined that it is not in the best interests of the Company or our stockholders.

------

##### [**Table of Contents**](#toc)

#### Allowing 10% of Stockholders to Call Special Meetings Would Be Costly, Disruptive and Benefit Only a Small Percentage of Stockholders
Allowing stockholders holding only 10% of the Company's outstanding common stock to call special meetings at any time and for any purpose could expose the Company and the Board to disruption by a small subset of investors or special interest groups whose objectives may not align with the best interests of the Company or our long-term stockholders.

Granting stockholders the right to call special meetings could also create substantial administrative and financial burdens and materially disrupt the Company's operations. Special meetings are expensive and time-intensive, given the preparation of required disclosure materials and associated printing and mailing expenses. Moreover, planning and executing a special meeting demands substantial time and attention from the Board, senior management and other key personnel, diverting their time and attention away from their primary responsibility of running the Company in the best interests of our stockholders.

The Board believes that special meetings of stockholders should only be called in extraordinary circumstances, when the Board or the Chairperson of the Board determines, in accordance with the Board's or the Chairperson's business judgment and the exercise of the Board's or the Chairperson's fiduciary duties, that it is in the best interests of stockholders to take the extraordinary step of convening a special meeting. As a result, our Third Amended and Restated Certificate of Incorporation provides that a special meeting of stockholders may only be called by the Board or the Chairperson of the Board.

#### We Have an Excellent Corporate Governance Structure
We are firmly committed to best-in-class corporate governance and have adopted a wide range of practices and procedures that promote effective governance, oversight and accountability. In addition, we employ a broad stockholder engagement program that provides management and our Board with valuable insight and feedback from investors throughout the year. We regularly engage with key stockholders to discuss, among other items, governance issues to ensure that management and the Board understand and address issues that are important to the Company's stockholders. Our Board believes that the corporate governance concerns raised by the Proponent are misplaced. Some of the Company's strong governance practices include the following:

• our governing documents do not contain any supermajority voting provisions;

• each of our directors is elected annually for a one-year term;

• all of our directors, except for the Company's President & Chief Executive Officer, are "independent" under the standards of the SEC and NYSE;

• each of the Board's Audit, Compensation, and Nominating and Corporate Governance Committees is composed solely of independent directors;

• we have a mandatory retirement age of 75 for directors (subject to waiver if the Board determines it to be in the best interests of the Company); and

• we have adopted proxy access, which allows stockholders owning at least three percent of the Company's common stock for three years to nominate, and include in the Company's proxy materials, director candidates constituting up to the greater of two nominees or 20% of the Board.

For the reasons described above, the Board believes the proposal is unnecessary and not in the best interests of the Company or our stockholders. Our current governance framework already provides robust stockholder rights and meaningful avenues for engagement while preserving the stability needed to execute the Company's long-term strategy.

#### The Board of Directors recommends a vote "AGAINST" the stockholder proposal to adopt a stockholder right to call special meetings.

OTHER INFORMATION

Other Business

Our Board does not know of any other matters that are to be presented for action at the Annual Meeting. If any other matters are brought before the meeting, the proxy holders will vote as recommended by our Board. If no recommendation is given, the proxy holders will vote in their discretion.

Proxy Solicitation

The expense of soliciting proxies will be paid by TransUnion. We have retained Georgeson LLC to assist with the solicitation of proxies at an estimated fee of $11,500 plus expenses. Some of the executive officers and other employees of TransUnion may solicit proxies personally, by telephone, mail, facsimile or other means of communication, if deemed appropriate. TransUnion will reimburse brokers or other persons holding stock in their names or in the names of their nominees for their reasonable expenses in forwarding proxy materials to beneficial owners of TransUnion's common stock.

Stockholder Proposals for 2027 Annual Meeting and Director Nominations

Under SEC regulations, if a stockholder wants us to include a proposal in our proxy statement and form of proxy for our 2027 Annual Meeting of Stockholders, our Corporate Secretary must receive the proposal at our principal executive offices at 555 West Adams Street, Chicago, Illinois 60661 by November 24, 2026.

Under our Bylaws, stockholders wishing to nominate a person for election as a director or to introduce an item of business at a meeting of our stockholders (but not include it in our proxy materials), must submit the proposed nominee or item of business by delivering notice to our Corporate Secretary at our principal executive offices, as follows:

• Normally, for an annual meeting, we must receive the notice not less than 90 days or more than 120 days before the first anniversary of the prior year's meeting. For our 2027 Annual Meeting of Stockholders, we must receive notice no earlier than January 12, 2027 and no later than February 11, 2027.

• However, if we hold the annual meeting on a date that is more than 30 days before or 70 days after such anniversary date, we must receive the notice not earlier than 120 days before such annual meeting and no later than the close of business on the later of (i) the 90<sup>th</sup> day before such annual meeting and (ii) the 10<sup>th</sup> day after the date on which public announcement of the date of the meeting is first made.

The notice is required to contain certain information set forth in our Bylaws about both the nominee or proposed business, as applicable, and the stockholder making the nomination or proposal. Any such proposal must also comply with the requirements of Rule 14a-8 of the Exchange Act. A nomination or proposal that does not comply with the foregoing requirements will be disregarded.

In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 13, 2027.

In connection with our 2027 Annual Meeting of Stockholders, the Company intends to file a proxy statement and a WHITE proxy card with the SEC in connection with our solicitation of proxies for that meeting.
