A letter to our Shareholders

Mark L. Feidler, Independent Chairman of the Board of Directors

Mark W. Begor, Chief Executive Officer

2024 marked an energizing chapter of transformation and growth for the New Equifax. We made significant progress towards the completion of our data and technology transformation, and as we look ahead to what’s next, we are building on the strong foundation of the Equifax Cloud™. In 2025 and beyond, we expect to drive competitive advantage as we pivot to leveraging the Equifax Cloud and focus fully on growth, innovation, new products, and our EFX.AI capabilities.

Equifax 2024 revenue of $5.68 billion was a record and up 8% on a reported and organic constant currency basis over 2023, delivering on the financial performance goals set at the beginning of the year against challenging U.S. mortgage and hiring macros. Our strong 2024 performance was aligned with our EFX2026 Strategic Priorities, and was an important inflection point in our ability to accelerate our free cash flow generation and to continue to drive growth through our investments in new products and targeted bolt-on acquisitions. Equifax is well-positioned to return capital to shareholders through both dividend growth and the launch of a multi-year share repurchase program in 2025 and beyond.

We entered 2025 with close to 85% of revenue in the Equifax Cloud, and with our United States Information Solutions (USIS) business unit, Canada, Chile and several other Latin American countries completing their consumer cloud customer migrations – a tremendous milestone after over 4 years of building the new Equifax Cloud. Our Cloud progress allowed us to decommission legacy systems and 10 additional data centers to deliver $300 million in spending reductions. Leveraging the power of the Equifax Cloud, we also delivered our fifth consecutive year of more than 100 New Product Innovations (NPIs) with a Vitality Index (defined as percentage of revenue from new products introduced in the last three years) of 12%, well above our 10% long term Vitality target for new products, while accelerating the development of advanced models and scores leveraging our market-leading EFX.AI capabilities. In 2024, 95% of our new models and scores were built using Artificial Intelligence (AI) and Machine Learning (ML), up from 75% in 2023.

International achieved more than a billion dollars in revenue for the fourth consecutive year, with 2024 revenue of $1.35 billion, up a very strong nearly 19% in constant currency year-over-year. Latin America continues to lead our International NPI with a 25% Vitality Index. In March 2025, we appointed Patricio Remon as our new President of Equifax International. Patricio joined Equifax in 2006, most recently serving as President of Equifax Europe, and brings deep global business knowledge, strong customer relationships, growth expertise, and a proven track record of outstanding leadership to the role.

U.S. Information Solutions delivered annual revenue of $1.89 billion, an increase of 10% from 2023. With the Equifax Cloud transformation of our U.S. Consumer and telecommunications and utilities exchanges complete, USIS accelerated its NPI growth, doubling the number of new products.

We made strong progress towards completing our Equifax Cloud Data and Technology Transformation in 2024, with USIS, Argentina, Canada, Chile, the Dominican Republic and Paraguay completing their Consumer Cloud customer migrations. We ended 2024 with the majority of our North America businesses and close to 85% of Equifax revenue in the Cloud as we pivot from building to leveraging the Cloud for innovation, new products, and growth. ​ With our USIS and Workforce Solutions Cloud migrations substantially complete, we are rapidly developing and bringing to market new OnlyEquifax™ solutions that include unique income and employment data from The Work Number® database and our USIS credit and alternative data assets. These OnlyEquifax solutions allow our customers to enhance their mortgage, auto, and personal loan originations by using credit attributes alongside income and employment information. | As a part of our Equifax Cloud transformation we have decommissioned 36 data centers to date, including 10 in 2024, with three additional data centers expected to be decommissioned by the end of March 2025. Decommissioning legacy on-premise systems and software reduces spending, improves operating margins, and lowers the capital intensity of our business. ​ New Product Innovation leveraging the Equifax Cloud enabled us to deliver a strong 12% Vitality Index in 2024 from broad-based, double-digit performances across all of our businesses, with new product revenue of about $650 million. ​ We were recognized in the inaugural TIME Magazine list of America’s Best Midsize Companies for organizations based in the U.S. with annual revenue between $100 million and $10 billion. Our inclusion in this prestigious list was based on strong performance in employee satisfaction, revenue growth, and responsible business practices. | We continued our EFX.AI innovation, and in 2024, 95% of our new models and scores were built using AI and ML, ahead of our 80% goal and up from 75% in 2023. We are seeing significant lifts in performance and predictiveness using EFX. AI and our differentiated data in models, scores, and new products. ​ The Work Number database reached 188 million active records, a 12% increase from 2023, with employment records for nearly 233 million people. We now have 4.2 million employers contributing payroll records to The Work Number database, and signed 15 new partnership agreements – including an agreement with Workday – that will drive record growth in 2025. ​ We continued our commitment to leadership in Security, evolving to meet – and anticipate – emerging cybersecurity threats in 2024 with a maturity level that has outperformed all major industry benchmarks for the last 5 years, a National Institute of Standards Technology (NIST) Cybersecurity Framework (CSF) score of 4.3, and an industry-leading passwordless transformation. Our roll-out of passwordless credentialing technology across Equifax, including the use of biometrics, helps eliminate the number one threat facing security teams: stolen credentials.

EFX2026: Delivering Against Our Strategic Priorities

​

Accelerate Innovation and New Products

​

In 2024, we leveraged the Equifax Cloud to accelerate New Product Innovation, marking our fifth consecutive year with over 100 new products developed. With a broad based 2024 Vitality Index of 12%, this was also our third consecutive year above our Long Term 10% Vitality Index goal. Revenue from new products was $650 million, with USIS notably seeing a 90% year-over-year increase in new product revenue.

Workforce Solutions continues to lead Equifax in NPIs with a nearly 15% Vitality Index and solutions powered by unique, differentiated data that expand our TotalVerify® data hub, including Talent Report™ High School. This solution provides instant verification of available U.S. high school diploma data to employers and background screeners during the pre-hire process through an exclusive integration with the National Student Clearinghouse®. And we continued our commitment to providing an extensive set of verification solutions for the mortgage industry with offerings like All Employers Within 90 Days, enabling credentialed lenders to verify a borrower’s income and employment information from the previous 90 days – useful in situations where a borrower has been employed at the same job for a long period of time and employment records beyond the last three months are not needed.

USIS introduced 28 new products in 2024 with a Vitality Index of 8.5%, including new offerings designed to give lenders and service providers the confidence they need to extend capital to small businesses in a rapidly changing economic environment. The new Equifax Cloud-based Merchant Data Network can improve traditional commercial scoring by more than 8% by providing valuable insights into the revenue small businesses generate from aggregated credit card transactions at the point of sale. The collaborative network combines the power of the Equifax Commercial Financial Network with aggregated credit card transaction data from Fiserv and other leading data providers to bring new visibility to more than 5.5 million businesses from more than 50 billion credit card transactions per year.

Our International business unit outperformed its 2023 results, delivering a Vitality Index of 10.4% and a total of 78 NPIs in 2024 – nearly half of which were multimarket offerings. The Equifax Cloud enables us to quickly extend the impact of our International Solutions by taking successful products from one market and easily introducing them into additional markets while maintaining compliance with local data and regulatory requirements. Multi-market solutions included a new suite of Equifax Scores that were first introduced in Argentina and then localized and launched in the Dominican Republic. These new, 100% Cloud-based scores leverage EFX.AI and our unique alternative data assets to bring new financial visibility to more consumers.

​

Our innovative technologies help drive Equifax products and solutions forward so that our customers and consumers can make critical decisions with greater confidence. As of January 2025, Equifax has more than 625 issued or pending patents across the globe. Our Cloud transformation is enabling us to deliver on patented innovation with a 52% year-over-year increase in original patent applications filed and 57% year-over-year increase in patents granted.

Leverage Equifax Cloud Capabilities

The Equifax Cloud is a top-tier global technology and security infrastructure that continues to set Equifax apart in the industry. We made strong progress against our Equifax Cloud data and technology transformation over the last year, including the migration of our USIS consumer and telecommunications and utilities exchanges to the Cloud. Along with The Work Number, which we migrated more than two years ago, we now have the majority of our North American businesses and three largest data exchanges in the new Equifax Cloud. We ended 2024 with close to 85% of Equifax revenue in the Cloud as we pivot from building to leveraging the Cloud for innovation, new products, and growth.

We also made substantial progress in our International technology transformation activities, completing our Canadian Cloud transformation, and moving Argentina, Chile, Costa Rica, the Dominican Republic, and Paraguay 100% to the Cloud in 2024. 2025 is also off to a strong start, with the migration of our consumer credit exchange in Spain completed in the first quarter. Our cloud-native infrastructure is already providing us with the competitive advantages of always-on stability, faster data transmission speeds, and industry leading security for our customers.

As a part of our Equifax Cloud transformation we have decommissioned 36 data centers to date, including 10 in 2024, with three additional data centers expected to be decommissioned by the end of March 2025. Decommissioning legacy on-premise systems and software reduces spending, improves operating margins, and lowers the capital intensity of our business. Our International Cloud migration efforts will continue in 2025 and 2026 resulting in additional cloud cost savings. In addition, our Cloud transformation significantly reduces the footprint of on-site technology and data centers and leverages the enhanced energy efficiency of cloud service providers.

As we near the finish line of our over $1.5 billion security, data, and technology transformation, we are confident that the Equifax Cloud will be central to our differentiation and our competitive advantage for years to come.

​

Expand Differentiated Data Assets

Unique, differentiated data and analytics continue to be at the heart of our business. With the Equifax Cloud, we are expanding the depth and accuracy of our data and helping our customers innovate faster to create more effective insights into the people and communities they serve. Central to the Equifax Cloud is our custom data fabric, an adaptable data platform that unifies the enterprise’s data (from over 100 siloed data sources) in a single, virtual structure, enabling critical data governance measures, including data segregation, and maintaining compliance with regulatory requirements.

Data fabric offers the ability to ingest and analyze our non-public data at scale, and enhances the keying and linking of our data assets for delivery of multi-data solutions.

​

Powered by the Equifax Cloud, our data fabric enables 40 million inquiries daily and ingests 15 billion records per month on a global basis.

In 2024, our differentiated, non-public data included:

​

​ | ​
The Work Number Database – 188 million active employment records and 734 million total employment records for verifications of employment and income from 4.2 million different U.S. employers. ​ Core Credit – More than 3.5 billion U.S. tradelines with over 1.6 billion updates monthly to currently reported accounts. ​ Relationship with the National Consumer Telecom and Utilities Exchange, Inc.® (NCTUE®) – Operation and management of the U.S. NCTUE database that includes more than 430 million telecommunications, pay TV, internet, home security and utility account records and their associated payments. ​ Insights – 198 million incarceration records from over 2,300 facilities across the United States. ​ IXI – Wealth information with more than $30 trillion in anonymized assets and investments. | DataX and Teletrack – Access to 120 million unbanked, underbanked and credit rebuilding consumers – enabling greater access to credit. ​ Partnerships for cash flow data – Information on balances, deposits and withdrawals from more than 7,700 participating U.S. financial institutions – allowing access to visibility of 96.5% of U.S. checking accounts. ​ Partnership with National Student Clearinghouse – Access to 130 million degrees from 2,700 colleges and universities. ​ Digital Solutions – Combined trust and fraud signals from more than 60 billion consumer interactions. ​ Commercial Financial Network – 194.4 million U.S. commercial tradelines across 76.7 million businesses.

​

Strategic partnerships are core to our differentiated data strategy. Last year, USIS extended its nearly 30-year relationship with the NCTUE, continuing our exclusive operation and management of the unique NCTUE database that includes more than 430 million account records and enabling us to deliver products and services that layer telecommunications, pay TV, internet, home security and utility insights on top of traditional credit data to help maximize consumer approval rates, help identify potential risks, reduce manual intervention costs and improve customer experience.

We also signed 15 new strategic partnerships in 2024, including Workday, which we expect will fuel Workforce Solutions verification services revenue growth in 2025. By integrating Workday Payroll and The Work Number employment and income verification service, Workday customers will be able to offer their employees seamless, instant verifications in support of their most important life events such as applying for a home mortgage, an auto loan, or government benefits.

Drive AI Innovation

The Equifax Cloud and our custom data fabric enable us to drive AI innovation and maximize our EFX.AI capabilities.

The successful use of AI requires deep, accurate and high-quality data. EFX.AI allows us to derive more value from our trusted, proprietary, non-public data – helping lenders and service providers make better decisions and open financial opportunities to otherwise underserved populations. In 2024, 95% of our new models and scores were built using AI and ML, ahead of our 80% goal and up from 75% in 2023.

We are well positioned to deliver continued strong, EFX.AI-powered new product growth leveraging the Equifax Cloud. New Cloud and AI-based scores in 2024 included the latest addition to the USIS OneScore suite of risk scores: the new OneScore for Alternative Finance. Designed to expand financial opportunities for consumers that may be credit invisible, unscorable, thin-file, or credit rebuilding, this new score leverages predictive insights from our DataX and Teletrack specialty finance data with the option to include traditional credit data. Our research indicates that OneScore for Alternative Finance could help boost approval rates by as much as 40% for consumers seeking new financial opportunities, with the potential to expand the scorable population to reach up to 97% of Americans seeking alternative finance loans.

Importantly, EFX.AI is aligned to both our EFX2026 Strategic Priorities and shared corporate values. Our approach is guided by our AI Governance Program, which sets strategic direction, provides global oversight of the use of AI systems, and defines the principles and practices that comprise Responsible AI at Equifax, with requirements that are aligned to the NIST AI Risk Management Framework. Whether it is for innovation, internal development, or operational improvements, Equifax uses AI Systems in a transparent, trustworthy, fair, explainable, and secure manner to provide benefits to consumers and customers.

​

2025 marks the 10-year anniversary of our patented Explainable AI (xAI) technology. Equifax led the way towards an industry standard for xAI in financial services, introducing the first machine learning credit scoring system with the ability to generate logical and actionable reason codes for consumers. Our AI innovation continues. As of January 2025, more than 300 of our pending and approved patents support our approach to AI. We infuse our patented AI techniques into solutions designed to enable customers to get to insights faster – helping to create new consumer opportunities.

​

Put Customers and Consumers First

Consumers and our customers depend on our data for important financial decisions and we take that responsibility very seriously. We began our Equifax Cloud, data and technology transformation to strengthen security and enhance our data quality and accuracy. With our North American Cloud transformation substantially completed in 2024, we have made significant improvements to our dispute process and consumer support, all with a goal of ensuring maximum possible accuracy. We believe that even one error affecting a consumer is one error too many, which is why we continue to invest in our data quality capabilities, technology, and processes to ensure that we can effectively detect and proactively remove inaccurate account information.

We transparently publish a monthly consumer credit report accuracy metric on our website, and in 2024 Equifax U.S. consumer credit report accuracy averaged 99.83% each month. This metric is determined by calculating the number of tradelines, collections, and bankruptcy disputes within the month that resulted in a change to a U.S. consumer credit report (regardless of whether that change had any impact on a consumer’s credit score).

​

Our Purpose is to help people live their financial best, and we strive to support economically healthy individuals and financially inclusive communities in each of the 24 countries where we do business.

Providing consumers with the resources they need to increase their financial capability is an important part of this. We are proud to provide ongoing credit education designed to help people understand both their personal finances and the credit system as well as the role we play in helping to provide access to mainstream, sustainable financial products. Examples of this include:

• We continue to evolve the experience for our 26.7 million myEquifax™ users to include access to new offers and services and we are introducing a mobile app in the second quarter of 2025 that will give consumers additional credit visibility.

• Building on our commitment to consumer education, our robust online U.S. Knowledge Center was updated to include a new Spanish-language hub designed to meet the needs of the 13% of the U.S. population that speaks Spanish at home.

• More than 2 million viewers have tuned in to our consumer credit video education series, “Equifax Learn,” on YouTube. And in 2024 we added a Spanish language version of the series to drive more awareness of our free translated U.S. credit report in Spanish, helping Spanish-speakers understand credit, know what information is in their credit report and get in the habit of monitoring their financial accounts.

Our New Product Innovation also plays a critical role in helping people live their financial best. In Canada, a new Global Consumer Credit File introduced in 2024 helps lenders make more confident credit lending decisions for newcomers to the country. The solution creates a calibrated credit score using newcomers’ credit histories from their countries of origin – essential in obtaining services such as housing, credit cards, and mobile phone contracts. Solutions ranging from our USIS Merchant Data Network and OneScore for Alternative Finance solutions, to our UK Open Banking and Open Finance offerings are designed to help global lenders responsibly create new financial opportunities by bringing more visibility to consumers and small businesses.

In 2024, we marked the 30th anniversary of Victim Information and Notification Everyday (VINE). VINE, acquired in our purchase of Appriss Insights in 2021, is the leading victim notification network in the U.S. It allows survivors, victims of crimes, and other concerned citizens to access timely and reliable information about offenders or criminal cases in U.S. jails and prisons. Last year, we saw nearly 6 million consumer registrations, 298 million offender searches, and nearly 22 million notifications to help keep victims of crime safe.

The Work Number plays a critical role in securing important financial moments such as starting a new job, leasing a car, applying for a mortgage, or seeking government benefits. The Work Number provided social service verifications for 25.5 million people seeking benefits while streamlining government operations and helping to ensure the integrity of safety net programs. Some of these programs include Medicaid, SNAP, Temporary Assistance for Needy Families (TANF), Housing Choice Vouchers, Supplemental Security Income (SSI), and more.

​

Execute Bolt-on M&A

Since 2018, we have invested more than $4.5 billion in 25 strategic bolt-on acquisitions to strengthen our core capabilities, grow our differentiated data assets, and drive future non-mortgage growth. These acquisitions have grown our talented team and have expanded our international footprint into new markets. In 2024 we focused our efforts on integrating acquisitions completed over the last two years to drive synergies across our business.

Just one year after the acquisition of Boa Vista Serviços, we are creating powerful new opportunities for Brazilian customers and consumers with the addition of our cloudnative products, decisioning and analytics capabilities, including our InterConnect® decision management system for easy access to data sources, attributes, models and decision rules. With Equifax|Boa Vista we are helping to drive new financial opportunities for the 34 million unbanked and underbanked consumers in Brazil, and customers are responding. In the fourth quarter of 2024 Equifax|Boa Vista saw double digit growth. We are continuing this strong momentum with a clear focus on leveraging our robust global platforms, and the completion of the Equifax|Boa Vista migration to the Cloud.

In 2022, we expanded our International footprint into the Caribbean with the acquisition of Data-Crédito, the largest consumer credit reporting agency in the Dominican Republic. Equifax República Dominicana was fully migrated to the Cloud last year and the legacy data center was decommissioned. With this transformation, our Dominican Republic team put the power of the Equifax Cloud into action with their powerful new localized Equifax Scores. In a country where 49% of the population is unbanked, these cloudbased scores are bringing new financial visibility to more consumers by combining our EFX.AI capabilities and unique alternative data for better insights.

​

Continue Leadership in Security

We continued to deliver on our commitment to being an industry leader in security. As our fifth consecutive publication of our Security Annual Report reflects, our maturity level has outperformed all major industry benchmarks for the last five years, exceeding Technology and Financial Services companies analyzed. Prioritizing security and building it into our systems – versus bolting it on – has become part of our culture and helps drive our performance with strong security underpinning our technology innovation.

We are constantly evolving to meet – and anticipate – emerging cybersecurity threats. In 2024 we completed an important milestone in transitioning nearly 22,000 full and part-time employees to passwordless authentication. Passwordless technology, including the use of biometrics, helps eliminate the number one threat facing security teams: stolen credentials. This change has also created a more seamless experience

for our global workforce. Removing the daily friction of passwords means that password resets, lockouts and Multi-Factor Authentication tools can be removed to save time and costs. Our passwordless environment also eliminates Knowledge- Based Authentication – the use of personal questions to verify a user’s identity – from internal helpdesk calls, ensuring that AI voice cloning and deep fakes cannot be used to trick agents into giving away access, online or on the phone.

We remain deeply committed to transparency, communication and collaboration – sharing our security resources for the benefit of the communities where we live and work. In 2024 we expanded our relationship with the Government of Costa Rica. Costa Rica is our third largest Equifax geography worldwide and our work with the country’s Ministry of Science, Innovation, Technology and Telecommunications is designed to boost the country’s cybersecurity, innovation and digital skills capacity at both the institutional and national levels. The new collaboration enables the sharing of Indicators of Compromise, the digital and informational “clues’’ used by incident responders to detect, diagnose, halt, and remediate malicious activity in their networks, fostering a better understanding of cyber threats. This collaboration will help strengthen cybersecurity at all levels.

We also continue to help the Costa Rican government build the cyber and technology talent pipeline in their universities. In 2024, the Costa Rican Commission for the Implementation of the National Framework of Qualifications approved the inclusion of a new cloud skills standard as part of the educational system. This has been the result of collaboration between the Costa Rican public sector organizations and expert private sector organizations, led by Equifax. Under this new standard, any technical schools in Costa Rica will be able to develop programs on cloud skills.

We are proud of the work that we do in helping organizations around the world become more secure and continue to actively engage with customers, policymakers, and other organizations regarding the challenges and opportunities in cybersecurity.

Act as One Team, One Equifax

We believe that our nearly 15,000 team members around the world are our greatest asset. Working together as One Equifax to drive cross-functional collaboration and innovation is critical to our success.

• As a values-driven organization, we are committed to nurturing a culture where everyone feels welcomed, valued and respected. Diversity of experience and thought drives increased creativity and innovation – which fuels our bottom line.

• In 2024, Equifax was named to the inaugural TIME Magazine list of America’s Best Midsize Companies, for organizations based in the U.S. with annual revenue between $100 million and $10 billion. Our inclusion in this prestigious list was based on strong performance in employee satisfaction, revenue growth, and responsible business practices.

Support for the communities where our employees live and work is core to our responsible business practices. Last year, the Equifax Foundation put our Purpose into action by making $1.3 million in direct charitable grants to community partners in Atlanta and St. Louis – including On The Rise Financial Center, Westside Future Fund, Prosperity Connection, and Credit Builders Alliance to help low-to-moderate income communities achieve the credit strength needed to live their financial best.

Through our Equifax Gives program, we matched more than $1 million in employee charitable donations in 2024 for more than $3.3 million in total community impact.

We also continued our direct community engagement, maintaining a strong commitment to employee volunteerism. Our BEST Credit Training, which trains U.S. based employees to deliver financial literacy content in their communities, provided more than 1,500 hours of training last year. We expanded our work with organizations like Junior Achievement, creating an Equifax storefront at the Atlanta-based Junior Achievement Finance Park where more than 30,000 students each year learn the basics of credit through real-life scenarios. And we doubled our UK community efforts, dedicating time and talent to organizations like Speakers for Schools. Over the last year we worked with more than 600 UK youth to help them learn more about credit, understand how to borrow responsibly, and avoid potential financial scams.

Internal career development remained a priority in 2024 and we continued to make a number of internal and external training opportunities available to our teams worldwide, with our global employees completing almost 170,000 hours of training and professional development. We also continued our work to enable employees to explore and map career options, identify and access targeted focus areas and development options matched to career desires, and easily access recommended internal job postings. We are proud to be a place where our employees can grow and develop their careers with nearly 50% of open roles filled internally in 2024.

2025 is a pivotal year for Equifax in our ability to accelerate our Free Cash Flow generation as capital expenditures come down and our EBITDA expands. Our strong Free Cash Flow conversion – which will approach our 95% long term goal – and leverage from expanding EBITDA, positions us to return capital to shareholders through both growing our dividend and launching a multi-year share repurchase program in 2025.

In 2025, we expect to deliver 6% constant dollar revenue growth, as well as adjusted EBITDA margin expansion of 25 basis points, with EBITDA increasing to over $1.9 billion despite our expectation of continued challenging end markets in mortgage and hiring. Adjusted EPS at the midpoint of guidance is expected to be $7.45 per share, up 2% versus 2024, with Free Cash Flow approaching $900 million.

We anticipate U.S. mortgage credit inquiries to decline 12% in 2025 compared to last year, and further expect U.S. hiring to be down about 8% relative to 2024, and on the order of over 10% below average hires over the last 10 years. Absent these assumed mortgage and hiring market declines, 2025 organic constant dollar revenue growth would be at the midpoint of our Long Term framework of 7 to 10% with EBITDA margins expanding over 100 basis points. As end markets normalize, we are confident in our ability to deliver organic revenue growth in our 7 to 10% Long Term framework, continue expanding adjusted EBITDA margins at 50 basis points per year, growing cash conversion to above 95%, and executing bolt-on M&A.

​

We are entering the next chapter of the New EFX with our Cloud transformation substantially complete with about 85% of EFX revenue in the Cloud. We are energized by our commercial momentum, New Product Innovation, EFX.AI capabilities, and the benefits of the new EFX Cloud, but even more energized about the future of the New Equifax!

​

On behalf of the Equifax Board, leadership team, and nearly 15,000 global employees, we thank you for your ongoing support and confidence in our business.

​

Thanks for your support,

Mark W. Begor

Chief Executive Officer and Director

Mark L. Feidler

Compensation Program Highlights

2024 Compensation Decisions

For the 2024 fiscal year, the Committee thoughtfully evaluated the compensation program structure in light of the ongoing evolution of our business strategy and shareholder feedback, when making decisions regarding the program. After evaluation, the Compensation Committee took certain actions with respect to our short- and long-term incentive programs for 2024, as summarized below and described in further detail under “Analysis of 2024 Compensation Decisions” beginning on page 62:

Our compensation program has been designed in response to direct shareholder feedback, and remained consistent with our prior year program (see page 62) |  | ● In designing the 2024 compensation program, the Compensation Committee conducted a thoughtful review, considering both the ongoing evolution of our business strategy and feedback from our shareholders ● During its deliberations, the Committee noted that our shareholders were broadly supportive of the structure and design of our core 2023 compensation program, including the use of performance-based equity award structures to drive alignment of the interests of our executives and shareholders ● As a result of this feedback, the Committee determined not to make any changes to our core compensation program for 2024 – As an example, our CEO’s target pay did not increase in 2024 relative to 2023
Our compensation program is designed to deliver payouts that align with performance (see pages 56-62, 66 and 76) |  | ● Our compensation program emphasizes long-term equity awards and annual performance-based cash incentives so that a majority of each executive’s total compensation opportunity is linked directly to the Company’s stock price or otherwise tied to performance – For 2024, 89% of target total direct compensation for our CEO and an average of 85% for the other NEOs was in the form of variable, at-risk pay ● Our annual and long-term compensation plans, including our 2024 compensation program, have operated by design to align CEO pay with our financial performance – In 2022-2024, although we achieved record revenues, our financial performance fell short of our enterprise targets due to the unprecedented declines in the U.S. mortgage market and challenging U.S. macroeconomic environment, which began in 2022 and continued through 2024; as a result, the annual incentive payout to our CEO, whose award is tied 100% to enterprise financial results, was below target in each of 2022, 2023 and 2024 – The TSR and Adjusted EBITDA performance shares granted in 2022 both paid out below target, reflecting the prolonged challenges to our business presented by U.S. macroeconomic factors

Compensation Best Practices

 Independent Compensation Committee advised by independent compensation consultant  Performance-oriented pay philosophy, as evidenced by a target pay mix for our CEO and other NEOs that is predominantly performance-based (see page 58)  Capped annual and long-term performance-based awards  Double-trigger change in control cash severance benefits and vesting of equity awards  No income tax gross-ups other than for certain relocation or foreign tax expenses  Performance shares are subject to a post-vesting holding period of 12 months |  |  Compensation clawback policy contains financial and reputational harm standard, including in supervisory capacity  Meaningful share ownership requirements for senior executives  Anti-hedging and -pledging policy for directors, officers and other employees  Senior executives cannot purchase or sell Equifax securities except pursuant to a Rule 10b5-1 trading plan with robust requirements  No re-pricing of underwater stock options  RSUs granted under our annual LTI program cliff vest at the end of three years

Proposal 1

Election of Director Nominees

All members of our Board are elected to serve until the next annual meeting of shareholders and until their successors have been elected and qualified. The ten nominees for election listed in Proposal 1 have consented to being named in this Proxy Statement and to serve if elected. All director nominees attended 75% or more of the aggregate of the meetings of the Board and of the committees of the Board on which such directors served during 2024. The Company does not have a policy about directors’ attendance at the annual meeting of shareholders, but directors are encouraged to attend. All of the directors then serving attended the 2024 Annual Meeting.

Our director nominees have a variety of backgrounds, which reflects the Board’s continuing objective to achieve a diversity of perspective and experience. As more fully discussed in “Process for Identifying Director Nominees” on page 34, director nominees are considered on the basis of a range of criteria, including their business knowledge and background, reputation and global business perspective. They must also have demonstrated experience and ability that is relevant to the Board’s oversight role with respect to Company business and affairs. Biographical information for each of the nominees is set forth on pages 23-32 and a Board matrix is set forth on page 33.

During his tenure, Equifax has grown from $3.4 billion of annual revenue in 2018 to record annual revenue of $5.7 billion in 2024, a compound growth rate of approximately 9%.

Process for Identifying Director Nominees

When the need to fill a new Board seat or vacancy arises, the Governance Committee proceeds in the manner it deems appropriate to identify a qualified candidate or candidates. Candidates may be identified through the engagement of an outside search firm, recommendations from independent directors, the Chairman of the Board, management or other advisors to the Company, and recommendations by shareholders. The Governance Committee Chair and Chairman of the Board are provided with copies of the resumes for any potential candidates so identified and review them as appropriate with the Governance Committee, our CEO and the full Board.

Our Governance Committee determines the selection criteria and qualifications for director nominees. As set forth in our Governance Guidelines, these criteria include, among other things, a director candidate’s integrity and ethical standards, independence from management, an ability to provide sound and informed judgment, a history of achievement that reflects superior standards and willingness to commit sufficient time. Cybersecurity is one of the skills that the Governance Committee specifically considers in its assessment of Board membership criteria. With respect to the most recent additions to the Board, the Governance Committee was also focused on expertise in accounting and finance, corporate governance, data and analytics, Equifax industry knowledge, international business, legal and regulatory, risk management, technology and strategy development.

Although the Committee does not have a formal diversity policy for Board membership, it considers whether a director nominee contributes or will contribute to the Board in a way that can enhance the perspective and experience of the Board as a whole through, among other things, diversity in professional background, education, gender, age, race and ethnicity. When current Board members are considered for nomination for re-election, the Committee also takes into consideration their prior Board contributions, performance and meeting attendance records. The effectiveness of the Board’s skills and expertise is also considered as part of the Board’s annual self-assessment.

Directors are limited to service on three other public company boards, not including our Board. Audit Committee members may not serve on the audit committee of more than three public companies absent a Board determination that such service will not impair the ability of such member to serve effectively on our Audit Committee. In addition, when our CEO is a member of our Board, he or she may not serve on more than two other public company boards. These policies – and our directors’ compliance with these policies – are reviewed at least annually and all directors currently comply with these limitations.

See “Questions and Answers about the Annual Meeting” beginning on page 125 for information on the procedures for shareholders to recommend director nominees for consideration by the Governance Committee.

Shareholder Engagement Program

Program Overview

Our Board of Directors and management team value the constructive feedback received from shareholders through our proactive and regular engagement. Investor engagement continues to prompt review of and changes to our governance practices, and our Board remains committed to seeking out and responding to investor feedback. Our integrated outreach team, led by our Office of Corporate Secretary and Investor Relations personnel, and joined by members of our Board for certain conversations, discusses a wide variety of issues with our shareholders.

2024 Outreach and Engagement

This past year, we continued our extensive outreach efforts, which follow an annual cycle centered around our annual meeting of shareholders.

Following our 2024 Annual Meeting, we reached out to shareholders holding approximately 78% of our outstanding common shares (“O/S”) and engaged with shareholders holding approximately 65% of our outstanding shares. We thoughtfully considered shareholder input on a range of topics, including Board governance and oversight, artificial intelligence, shareholder rights, data accuracy and consumer experience, employee engagement and more. Our Independent Board Chair and our Compensation Committee Chair led several of these engagement meetings. We included outreach to both of the leading proxy advisory firms as part of our engagement efforts.

Board Leadership Structure

The Board annually reviews its leadership structure and our governance documents provide the Board with the flexibility to select the appropriate leadership structure for us at any given time. In 2017, the Board decided to adjust its leadership structure to separate the roles of Chairman and CEO. Mark Feidler, who had previously served as a leader for the independent directors in his role as Presiding Director, was elected to the role of Independent Chairman. In selecting Mr. Feidler to serve as Independent Chairman, the then-serving independent directors considered, among other things, his effective leadership when serving in the role of Presiding Director and his ability to commit sufficient time to the additional workload and increased meeting attendance as important qualifications.

The Board has determined that having separate Chairman and CEO roles is in the best interest of the Company and its shareholders at this time. This structure provides for direct independent oversight of management and clearly delineates the role of the Board as a source of insight and oversight for management. The Board believes this leadership structure, which also includes a majority independent Board and fully independent Board committees, best serves the objectives of the Board’s independent oversight of the Company’s business and affairs.

​ ​ | ​ ​
| Mark L. Feidler INDEPENDENT CHAIRMAN OF THE BOARD

The role and responsibilities of Independent Chairman include:

· Calling meetings of the full Board or of the non-management directors · Establishing the agenda for each Board meeting, in coordination with the CEO · Presiding at all meetings of the Board · Advising the CEO of decisions reached and suggestions made at the executive sessions of the non-management directors | · Facilitating communication between the directors and with the CEO · Meeting directly with management and other employees of the Company · Presiding at meetings of shareholders and calling special meetings of shareholders · Being available for consultation and direct communication with shareholders

Board Self-Evaluation Process for 2024-2025

This year, based upon the recommendation of the Governance Committee, the Board determined it was appropriate to implement its standard process for the 2024-2025 self-evaluation cycle. Under the standard process, each director completed written Board and committee evaluation questionnaires, which were aggregated by the Office of Corporate Secretary without individual attribution and reviewed by the Independent Chairman as well as the committee chairs. The Independent Chairman participated in one-on-one discussions with each of the other directors, during which they discussed the response summaries, and reviewed the evaluation results with the full Board in February 2025. In addition to the Board self-evaluation, each standing committee conducted its own self-evaluation and charter review.

| Feedback Incorporated Over the past few years, the evaluation process has highlighted opportunities to strengthen the effectiveness of the Board’s practices, structures, competencies and communications. Key themes for this year’s evaluation included: ● Areas of strategic focus and Board composition in support of long-term strategy ● Balance and scope of topics and materials covered in Board meetings ● Board engagement and communication with management ● Management, director and committee succession planning

Director Independence

Our Governance Guidelines provide that a substantial majority of our Board should be independent. Our Guidelines for Determining the Independence of Directors, which is an appendix to our Governance Guidelines and may be accessed on our website at www.equifax.com/about-equifax/corporate-governance, meet or exceed the requirements of SEC rules and regulations and the NYSE listing standards.

The Board has affirmatively determined that all director nominees (other than our CEO, Mark Begor) are independent under the applicable NYSE listing standards, SEC rules and our Guidelines for Determining the Independence of Directors. In making these determinations, the Board considered the types and amounts of the commercial dealings between the Company and the companies and organizations with which the directors are affiliated. The Board views the independence analysis as an ongoing consideration and will continue to monitor these relationships.

Each director is an equal participant in decisions made by the full Board. All of our standing Committees are comprised solely of independent directors.

Board Refreshment and Succession Planning

Board Refreshment

The Governance Committee regularly assesses the requirements of the Board and makes recommendations regarding its size, composition and structure. The Governance Committee is focused on how the experience and skill set of each individual director complements those of fellow directors to create a balanced Board that reflects a mix of viewpoints, skills and expertise through members with a diversity of professional experience, education, gender, age, race and ethnicity. As part of its ongoing strategic review regarding Board refreshment, the Governance Committee seeks to anticipate future needs for expertise in cybersecurity, data and analytics, international business operations and technology. Among other things, the Governance Committee considers committee composition and chair rotation as part of its overall succession planning process.

The Governance Committee and the Board actively seek new director candidates that can provide valuable guidance as we focus on executing our strategic priorities by fully leveraging the Equifax Cloud and our EFX.AI advanced analytics and machine learning capabilities to drive innovation, new products and growth. The Board believes that the additions of Melissa Smith in 2020, Audrey Tillman in 2021, Karen Fichuk in 2023 and Barbara Larson in 2024 have provided our Board with additional broad-based executive leadership experience, as well as enhanced expertise in accounting and finance, corporate governance, cybersecurity, data and analytics, Equifax industry knowledge, international business, legal and regulatory, risk management, technology and strategy development.

The Board will continue to seek out highly-qualified director candidates as part of the Board succession plan to enhance the composition of our Board to align with our overall strategy.

Board Tenure and Succession Planning

Pursuant to our Bylaws and Governance Guidelines, we have a mandatory retirement age of 72, after which a director will not be elected or re-elected unless the Governance Committee and Board determine that the continued service of the director on the Board would be of benefit to the Company. The following chart shows the individual and average tenure of our director nominees, which is well distributed to create a balanced Board. Since 2020, we have refreshed our Board with four new directors who bring valuable perspective and expertise.

Committee Tenure and Refreshment

The Governance Committee is responsible for reviewing the composition of the committees of the Board. In its review of committee composition, the Governance Committee considers the responses collected during the Board and committee annual self-evaluations, as well as the past experience and relevant skills of each director. The Governance Committee and the Board annually consider the composition of the committees of the Board to ensure each committee has the appropriate relevant mix of skills and experience.

Director Orientation and Continuing Education

Upon joining our Board, our directors participate in an orientation program regarding our Company, including business operations, strategy, regulatory compliance, cybersecurity, governance and company policies. In addition to the onboarding process, our Board receives regular updates from management regarding the Company’s operating plan and strategy, including updates specific to each business unit and the enterprise as a whole. In addition to these regular reports, the Board receives periodic updates from management and third parties, as appropriate, regarding regulatory compliance, government relations, investor perspectives, artificial intelligence, shareholder activism and other Board governance topics. The Board also conducts periodic visits to our key facilities. Our directors participate in annual cybersecurity training and receive annual updates on our crisis management program in order to ensure enterprise preparedness. Board members also may attend outside director continuing education programs at Company expense to assist them in keeping pace with developments in corporate governance and other critical issues relating to the operations of public company boards.

Management Succession Planning and Talent Development Process

Our Board is accountable for the development, implementation and continual review of a succession plan for the CEO and other executive officers. The Governance and Compensation Committees jointly oversee the succession planning process for the CEO and the Compensation Committee oversees the succession planning process for other executive officers. The Compensation Committee monitors each of the CEO’s direct reports for high potential internal CEO succession candidates, all of whom have ongoing exposure to the Board and are reviewed annually with the Board by the CEO and the Chief Human Resources Officer. The Compensation Committee and the Board also review the foregoing in executive session on a regular basis. The Board’s process ensures that critical business capabilities are safeguarded, executive development is prioritized and strategic talent is leveraged to focus on current and new business imperatives.

We adopted the National Institute of Standards and Technology (NIST) AI Risk Management Framework (“NIST AI Framework”) as the foundation for managing AI risks across our company. The NIST AI Framework complements our NIST-aligned Security and Privacy Controls Framework and helps us define actionable requirements for managing AI risks.

We established AI Controls and Operational Requirements to integrate the NIST AI Framework into our business operations. We mapped these AI Controls and Operational Requirements to our overall Compliance Control Framework to help ensure we meet regulatory requirements for our use of AI systems and establish a unified set of requirements across the Company.

To implement our AI Controls and Operational Requirements, we published a global AI Policy. Where possible, we leverage existing governance and oversight processes and Standard Operating Procedures to address the risks associated with using AI, further supporting end-to-end governance and oversight.

How We Manage Risk

We have a comprehensive enterprise risk management (“ERM”) program focused on the application of controls over the following primary risk types:

​ | ​ | ​
· Compliance · Cybersecurity · Data and Privacy | · Financial · Legal · Operational | · Reputational · Strategic · Technology

In addition to the categories set forth above, we have a process under our ERM program for identifying other risks that could adversely affect our business, including risks related to responsible business-related matters. Our Audit Committee annually reviews our policies and processes with respect to risk assessment and risk management.

We have implemented an ERM framework based on the “three lines of defense” model for establishing effective checks and balances, which is used by leading financial institutions.

LINES OF DEFENSE
1 OPERATIONAL |  | 2 RISK & COMPLIANCE |  | 3 INTERNAL AUDIT DEPARTMENT
The first line of defense, the operational line, is the business unit or corporate support unit, such as IT, data security, finance and human resources. Business unit and corporate support unit leaders are directly responsible for managing risks and controls in their operations. |  | The second line of defense provides risk and regulatory compliance oversight, and is primarily comprised of the Enterprise Risk Management and Compliance organizations within Equifax. These functions have a direct reporting channel to the Board and are responsible for establishing frameworks, policies and standards, performing independent risk-based monitoring and testing, and independently identifying and assessing material risks, including IT and data security risks. |  | The third line of defense, the internal audit department, as supplemented by third party support, audits the effectiveness of the oversight of the second line of defense and performs direct audits of the first line of defense. Internal audit is responsible for providing the Audit and Technology Committees and senior management with an independent assessment and assurance regarding the design and effectiveness of the risk management framework.

The execution of our ERM program is supervised by our Compliance organization, with each business unit and corporate support unit having primary responsibility for assessing and mitigating risks within its respective areas of responsibility. Our Chief Privacy and Compliance Officer leads the ERM organization and function and meets regularly with the Board, the Audit Committee and the Technology Committee. A Risk Program Governance team develops, enhances, deploys and manages risk program elements.

Related Person Transaction Policy

The Board has adopted a written policy for approval of transactions between the Company and its directors, director nominees, executive officers, greater than 5% beneficial owners and their respective immediate family members (each, a “Related Person”), where the amount of the transaction is expected to exceed $120,000 in a single calendar year.

The policy provides that the Audit Committee reviews transactions subject to the policy and decides whether or not to approve those transactions. In doing so, the Audit Committee determines whether the transaction is in the best interests of the Company. In making that determination, the Audit Committee takes into account the following, along with other factors it deems appropriate:

| ● | the extent of the Related Person’s interest in the transaction;

| ● | whether the transaction is on terms generally available to an unaffiliated third-party under the same or similar circumstances;

| ● | the benefits to the Company;

| ● | the availability of other sources for comparable products or services; and

| ● | the terms of the transaction.

The Governance Committee also determines the impact or potential impact on a director’s independence in the event the Related Person is a director, an immediate family member of a director, or an entity in which a director is a partner, shareholder or executive officer.

Certain Relationships and Related Person Transactions of Directors, Executive Officers and 5 Percent Shareholders

During 2024, the Company was not a participant in any transaction or series of transactions in which the amount involved did or may exceed $120,000 in which any Related Person had or will have a direct or indirect material interest, other than the compensation arrangements (including with respect to equity compensation) described in “Executive Compensation” beginning on page 54 and “Director Compensation” beginning on page 111.

Our Incentive Programs Align Payouts with Financial Performance and Non-Financial Goals

Our 2024 compensation program metrics, established in the first quarter of 2024, were:

Annual Incentive Plan (AIP) Opportunity
Payouts are based on the attainment of financial goals and individual non-financial strategic goals | Financial Goals ● Corporate Operating Revenue measures our top line business growth 1, 2 ● Corporate Adjusted EPS measures our profitability 1, 2 Individual Non-Financial Strategic Goals Individual goals aligned with our strategic priorities (see page 65): ● Accelerate Innovation and New Products ● Leverage Equifax Cloud Capabilities ● Expand Differentiated Data Assets ● Drive AI Innovation ● Put Customers and Consumers First ● Execute Bolt-on M&A ● Continue Leadership in Security ● Act as One Team, One Equifax Payouts Align With Performance Our NEOs’ 2024 AIP awards paid out between 95%-118% of target in alignment with our performance against financial goals (see page 66)

​

Long Term Incentive (LTI) Plan Opportunity
Designed to strike a balance between stock market-based and operational performance | Financial Performance Metrics ● Performance shares tied to three-year cumulative TSR measuring our stock performance relative to companies in the S&P 500, providing a broad index for comparison and alignment with shareholder investment choices - If our cumulative three-year TSR is negative, the payout is capped at target (100%), regardless of our relative TSR percentile ranking ● Performance shares tied to Adjusted EBITDA are earned based on our Adjusted EBITDA performance over a three-year period 3 - If we fail to meet our threshold Adjusted EBITDA goals for any year during the three-year performance period, the payout for that year will be $0 Payouts Align With Performance TSR and Adjusted EBITDA performance shares granted in 2022 vested in 2025 at 68.6% and 61.7% of target, respectively (see page 76)

1 | Corporate Operating Revenue and Corporate Adjusted EPS, as used for corporate-level financial goals under the AIP, are non-GAAP measures. Corporate Operating Revenue is Operating Revenue adjusted to be stated in constant dollars at our budgeted 2024 foreign exchange rates. Corporate Adjusted EPS is Adjusted EPS as shown in Annex A to this Proxy Statement, and then further adjusted to be stated in constant dollars at our budgeted 2024 foreign exchange rates. Because of these adjustments to Operating Revenue and Adjusted EPS, the actual Corporate Operating Revenue and Corporate Adjusted EPS used for incentive management purposes are not the same as Operating Revenue and Adjusted EPS reported under our “2024 Financial Highlights” on page 55.

2 | Certain of our NEOs had roles for 2024 for which their AIP outcome was tied to specific business unit-level financial goals, as described in further detail under “Analysis of 2024 Compensation Decisions” beginning on page 62.

3 | Adjusted EBITDA is a non-GAAP measure, as shown in Annex A to this Proxy Statement.

Say-on-Pay Voting Results in 2024

In evaluating our executive compensation program, one factor our Compensation Committee considers is the results of the most recent annual shareholder advisory vote on executive compensation, or “say-on-pay”, vote. At our 2024 Annual Meeting, approximately 91% of the votes cast approved our executive compensation program. Following our 2024 Annual Meeting, the Committee continued to review our compensation program and practices and how they align with our core compensation philosophy, market best practices and our strategic priorities. The Committee continues to take steps to ensure that pay opportunities are performance-based, with a mix of fixed and at-risk variable pay that ensures alignment between management and shareholder interests.

Shareholder Engagement on Executive Compensation

As part of our Board-directed shareholder engagement program, feedback received from shareholders on our executive compensation program is shared with the Compensation Committee and the full Board. The Compensation Committee considers this feedback, as well as the compensation plan and benchmarking advice from its independent compensation consultant, in its review of our compensation program.

Following the 2024 Annual Meeting, members of our management team, together with our Compensation Committee Chair or our Independent Board Chair for certain conversations, conducted investor outreach meetings with investors representing approximately 65% of our shares. During these meetings, our shareholders:

| ● | expressed support for our core compensation program, including our use of performance-based equity award structures to drive alignment of the interests of our NEOs and shareholders; and

| ● | described their priorities and provided constructive feedback regarding various topics.

This feedback informed the Committee’s decisions with respect to the design of our 2025 compensation program, which remains consistent with our 2024 program, as more fully described under “Actions Taken with Respect to 2025 Compensation” on page 76.

Taking account of shareholder feedback, we continue to improve our proxy disclosures regarding the structure of our executive compensation program. We will continue to evaluate and integrate this feedback into the Committee’s discussions, including topics such as metrics that are used to determine the NEOs’ short- and long-term incentive compensation.

Compensation Program Highlights

Executive Compensation Philosophy

| ● | The Compensation Committee is responsible for the Company’s executive compensation policies and plans.

| ● | The Committee works to ensure that incentives are performance-based and aligned with shareholders’ interests, while guarding against metrics or goals that create inappropriate or excessive risk reasonably likely to have a material adverse effect on the Company.

| ● | The Committee has designed and regularly reviews our compensation program to ensure we are providing competitive pay opportunities to attract and retain executive talent and to incentivize achievement of strategic and financial goals.

2024 Target Pay Mix

As illustrated in the charts below, the Company emphasizes long-term equity awards and annual performance-based cash incentives so that a majority of each executive’s total compensation opportunity is linked directly to the Company’s stock price or otherwise tied to performance. For 2024, 89% of target total direct compensation for our CEO and an average of 85% for the other NEOs was in the form of variable, at-risk pay. Moreover, 80% of long-term incentive awards for our CEO and 75% of long-term incentive awards for our other NEOs was in the form of performance-based compensation (performance shares and stock options).

* | Percentages calculated based upon actual base salary, target annual incentive and the target grant date value of annual long-term incentive awards, excluding special awards. Percentages may not total 100% due to rounding.

Compensation Design Process

Role of the Compensation Committee and Management in Determining Executive Compensation

The Compensation Committee reviews and makes decisions about executive compensation, including the amount of base salary, short-term incentives and long-term incentives awarded to our NEOs. Our CEO and other executives may assist the Committee from time to time in its evaluation of compensation elements or program design or by providing mathematical calculations, historical information, year-over-year comparisons and assessments of performance and potential. For the 2024 AIP and 2024 LTI program, the Committee considered recommendations from members of management regarding the performance measures and targets, including the individual non-financial strategic goals under the AIP. The Compensation Committee also considers recommendations from its independent compensation consultant and competitive data and makes decisions on executive compensation based on its assessment of individual performance and achievement of goals by both the individual and the Company.

The CEO’s performance is reviewed by the Compensation Committee with input from the other non-employee members of the Board. The CEO annually reviews the performance of each executive officer who reports to him, including the NEOs. The conclusions reached and recommendations made based on these reviews, including with respect to salary adjustments and annual award amounts, are presented to the Compensation Committee for approval and to the Board for review. Members of management play various additional roles in this process:

| ● | The CEO makes recommendations to the Committee regarding the design of performance measures for our AIP and the design of our LTI program, as well as compensation packages for the executive officers (other than himself) based on his evaluation of the performance, experience, long-term potential and leadership of the executives who report to him.

| ● | The Chief Human Resources Officer provides the Committee with details regarding the operation of our compensation plans, including the design of performance measures for our AIP and the design of our LTI program. The CHRO also facilitates a robust performance evaluation process and succession planning discussions.

| ● | The Chief Financial Officer provides information and analysis relevant to the establishment of financial performance targets for our performance-based annual and long-term incentive awards and presents information regarding the attainment of corporate and business unit financial goals for the preceding year.

| ● | The Chief Legal Officer attends meetings of the Committee to provide input on legal issues, to communicate investor perspectives on our pay program based on shareholder engagement efforts, and to respond to questions about corporate governance and executive compensation.

Although members of management participate in the executive compensation process, the Compensation Committee makes the final determination regarding our overall compensation program design and the compensation provided to each of our NEOs.

Compensation Consultant Services and Independence

The Compensation Committee has the authority to engage advisors to assist it in fulfilling its responsibilities. The Committee retained Frederic W. Cook & Co., Inc. (“FW Cook”), a nationally-recognized executive compensation consulting firm, to provide advice with respect to 2024 compensation for our CEO and other executive officers. FW Cook performs services solely on behalf of the Committee and does not provide any other services to the Company. Management had no role in selecting the Committee’s compensation consultant and has no separate relationship with FW Cook. The Committee has assessed the independence of FW Cook pursuant to SEC and NYSE rules and concluded that no conflict of interest exists that would prevent FW Cook from independently representing the Committee. In 2024, FW Cook assisted the Committee in determining appropriate levels of compensation for the CEO and other executive officers for 2024, advising on the structure of variable incentives and assisting the Committee in evaluating performance goals.

Benchmarking Use of a Peer Group

Compensation Peer Group

Robust Annual Review Process

We are a global data, analytics and technology company. We provide information solutions for businesses, governments and consumers, and we provide human resources business process automation and outsourcing services for employers. The market for our products and services is highly competitive and is subject to change. Our direct competitors vary widely in size and in the nature of the products and services they offer.

The Committee regularly evaluates whether the compensation opportunities for our executives are appropriate and competitive by comparing each NEO’s target compensation opportunity to the compensation opportunities for executives in comparable positions at peer companies. The Committee considers the pay practices of our peer companies as a primary factor when setting target pay opportunities for our executives. However, the Committee also believes that compensation decisions are multi-dimensional and require consideration of other factors, including relevant industry data, market competition, internal pay equity and each individual executive’s performance, experience, long-term potential and leadership contributions.

The Committee conducts an annual review of our peer group, with the assistance of FW Cook, to ensure the selected companies continue to reflect our business strategy and the evolving market in which we compete for business. Most importantly, the Committee seeks to ensure that the peer group also includes competitors for talent, as our labor market for executive leadership extends across the highly competitive technology and technology-enabled industries. The peer group selection process further refines these business and labor market competitors to only include companies that are similar to us in scale and business complexity.

Business Evolution and Impact on Peer Group

Since 2018, our market capitalization has increased by 2.7x and we have transformed into a faster growing, diversified data, analytics and technology company that has expanded well beyond a traditional consumer credit bureau. Our peer group has evolved along with our business. During the past several years, the Committee has made changes to our peer group to align with our size, growth orientation and business strategy and to more closely reflect companies we consider competitors for executive talent.

In particular, the Committee has sought to ensure that our peer group continues to reflect the significance of Workforce Solutions, our largest and fastest-growing business segment. We have added peers over time to reflect our Workforce Solutions services offerings (including peers that provide global cloud based financial and human capital management software and application services and related outsourcing solutions). We have also added peers we consider competitors for executive talent (including peers that provide credit ratings, data analytics and workflow solutions, and mortgage technology data and analytics).

Although the Committee reviews the compensation peer group annually, the Committee does not change the peer group annually. We last made changes to our peer group in May 2022.

2024 Peer Group

In May 2023, following annual review and based on the recommendations of FW Cook, the Committee determined it would be appropriate to retain the same 15-company peer group for 2024 that was utilized in 2023. The Committee utilized this peer group in February 2024 when setting NEO pay levels under the 2024 compensation program.

The companies comprising our 2024 compensation peer group were as follows:

Automatic Data Processing, Inc. | Gartner, Inc. | Paychex, Inc.
Broadridge Financial Solutions, Inc. | Global Payments, Inc. | S&P Global Inc.
Fidelity National Information Services | Intercontinental Exchange, Inc. | TransUnion
Fair Isaac Corporation (FICO) | Intuit Inc. | Verisk Analytics, Inc.
Fiserv, Inc. | Moody’s Corporation | Workday, Inc.

​

​

Table of Contents

2025 Peer Group

Following annual review in May 2024, the Committee determined to retain the same 15-company peer group described above for purposes of setting 2025 compensation levels.

Peer Group for Performance Shares

The peer group described above was deemed appropriate for compensation purposes, although the stock performance of those companies is not necessarily impacted by the same economic factors as ours. Moreover, investors are likely to compare Equifax to other companies in the S&P 500 Index (of which we are a member). For that reason, the Compensation Committee believes that a broader peer group is more appropriate for evaluating TSR performance for performance shares issued under our LTI program. Therefore, the Committee uses the companies in the S&P 500 Index as the comparative group for that purpose.

Use of “Tally Sheets”

On a regular basis, the Compensation Committee reviews “tally sheets” relating to compensation of the NEOs. For each executive, the tally sheets quantify the executive’s total compensation package, the impact of stock price changes on the value of existing long-term incentives, the wealth created from prior equity grants and amounts payable upon hypothetical employment change events. These summaries allow the Committee to assess the cumulative impact of its past compensation decisions and to evaluate retention risk. Tally sheet review in 2024 did not lead to any specific compensation program changes.

Other Factors Considered in Setting Pay Opportunities for NEOs

The CEO and the Compensation Committee consider a number of factors in addition to the market data in determining individual pay amounts. Such factors include an individual’s level of performance, the individual’s demonstrated success in meeting or exceeding business objectives and creating shareholder value, job market conditions, our operating environment and business challenges, the individual’s importance to our business, succession planning considerations and the individual’s pay in the context of others at the Company. The application of discretion based on such factors may result in pay opportunities that are different from market. Overall compensation opportunities reflect our executives’ positions, responsibilities, performance, leadership and tenure. In the case of our CEO, the terms of his employment agreement are also relevant.

Analysis of 2024 Compensation Decisions

Context for 2024 Compensation Decisions

At our 2023 Annual Meeting, the advisory vote on executive compensation, or “Say-on-Pay” vote, failed to receive support from a majority of votes cast. Following the 2023 Annual Meeting, our Compensation Committee, Governance Committee and entire Board were focused on understanding and responding to our shareholders’ feedback as reflected in the 2023 Say-on-Pay vote.

During the summer and through the fall of 2023, we conducted extensive engagement with shareholders to capture their feedback on our compensation program. During these discussions, shareholders generally expressed strong support for the structure and design of our core compensation program. Instead, we heard that most investors do not favor one-time awards and that investors who voted against our Say-on-Pay proposal in 2023 did so due to concerns about the possibility of additional one-time awards being granted to our CEO. In response to this feedback, the Compensation Committee committed that it does not intend to grant any future one-time awards to our CEO or other NEOs (beyond the awards granted in the process of hiring new employees) absent extraordinary circumstances.

In view of the shareholder feedback received, the Compensation Committee concluded that a change to our 2023 core compensation program would not be responsive to shareholder feedback. In designing our 2024 compensation structures and target pay levels, the Committee sought to ensure that the compensation program reflected our strategic business priorities, while also ensuring that the Company could attract and retain talented employees in order to create value for shareholders and provide appropriate incentives for executives managing those efforts.

2024 Annual Cash Incentive Structures and Outcomes

Summary

Annual cash incentive awards are designed to reward the achievement of near-term business goals in alignment with our strategic business priorities. Moreover, these awards are structured to ensure that payouts are aligned to performance and shareholder experience. In addition to financial metrics, annual incentive awards are based on an assessment of individual contributions toward the achievement of business and strategic goals.

The 2024 corporate financial performance goals for the NEOs with Company-wide responsibilities were based on Corporate Operating Revenue (used to measure top line business growth) and Corporate Adjusted EPS (used to measure profitability). We refer to this as the Corporate Plan. The financial goals for business unit leaders were focused primarily on relevant business unit revenue and operating income performance (used to measure business unit growth and profitability), as well as Corporate Adjusted EPS (to emphasize profitability of the Company as a whole). We refer to these as Business Unit Plans.

When setting the range of performance goals for the Corporate Plan and the Business Unit Plans at the outset of the fiscal year, the Compensation Committee considers our financial results from the prior year and our annual operating budget for the coming year. The Committee also considers the history of goal attainment in prior years, economic and industry conditions, industry sector performance and the views of our shareholders.

Establishment of Corporate-Level Financial Goals

The Compensation Committee established corporate-level financial goals required to earn a cash incentive award for 2024 in a manner that was designed, within reasonable limits, to encourage achievement that exceeds target goals and penalizes underachievement. The financial goals under our compensation program are established with reference to our annual operating budget, which is approved by the Board. We set challenging but achievable goals, including maximum payout opportunities requiring exceptional performance for the Company and our executives in order to drive the achievement of our short-and long-term objectives.

The 2024 threshold, target and maximum levels for Corporate Operating Revenue were each set above 2023 levels, and above 2023 actual results. The 2024 threshold, target and maximum levels for Corporate Adjusted EPS targets were set above 2023 levels. The 2024 target and maximum goal levels were set above 2023 actual results, while the 2024 threshold level for Corporate Adjusted EPS was set slightly below our 2023 actual results, due to the unprecedented declines in the U.S. mortgage market that began in 2022 and continued throughout 2023 and 2024.

In setting the corporate-level financial goals under the 2024 AIP, the Compensation Committee considered (i) our 2024 operating budget, (ii) our 2024 financial outlook as of February 2024 (including assumptions related to global macroeconomic factors, U.S. mortgage market conditions and business unit growth trends for 2024) and (iii) our strategic priorities, taking into account the initiatives to be implemented during 2024. Although we achieved record revenue in 2023, our financial performance fell short of our targets due to the unprecedented declines in the U.S. mortgage market and a softening of the global macroeconomic environment. The Compensation Committee was mindful of these external, macroeconomic factors when setting the 2024 AIP goals. In designing the 2024 compensation structures and target pay levels, the Committee sought to ensure that the compensation program reflected our financial and strategic business priorities, while also ensuring that the Company could attract and retain talented employees in order to create value for shareholders and provide appropriate incentives for executives managing those efforts.

1 | Corporate Operating Revenue and Corporate Adjusted EPS, as used for the corporate-level financial goals under the AIP, are non-GAAP measures. Corporate Operating Revenue is Operating Revenue adjusted to be stated in constant dollars at our budgeted 2024 foreign exchange rates and further adjusted. Corporate Adjusted EPS is Adjusted EPS as shown in Annex A to this Proxy Statement and then further adjusted to be stated in constant dollars at our budgeted 2024 foreign exchange rates. Because of these adjustments to Operating Revenue and Adjusted EPS, the actual Corporate Operating Revenue and Corporate Adjusted EPS used for incentive management purposes are not the same as Operating Revenue and Adjusted EPS reported under our 2024 Performance Highlights above.

2 | Mr. Begor’s AIP awards are determined based exclusively on achievement measured against Company financial goals (rather than 80% financial goals and 20% individual objectives). As a result, his 2024 AIP payout was based upon our Corporate Adjusted EPS (81.25% weighting) and Corporate Operating Revenue (18.75% weighting).

Establishment of Business Unit-Level Financial Goals

The Compensation Committee reviewed and approved a Business Unit Plan for each of our business units. The Compensation Committee established business unit-level financial goals required to earn a cash incentive award for 2024 in a manner designed, within reasonable limits, to encourage achievement that exceeds target goals and penalizes underachievement. Each Business Unit Plan included a corporate-level financial goal (Corporate Adjusted EPS) at a 30% weighting.

In 2024, Messrs. Borton and Ploder participated in the Business Unit Plan for the Workforce Solutions business unit and Mr. Horvath participated in the Business Unit Plan for the USIS business unit. The 2024 business unit objectives for Messrs. Borton, Ploder and Horvath are set forth below.

USIS Plan

The 2024 target and maximum levels for USIS operating revenue were set above 2023 levels, with threshold equal to 2023 actual results. The 2024 target and maximum levels for USIS operating income were set above 2023 levels and above 2023 actual results. The threshold operating income level was set below 2023 actual results due to the unprecedented declines in the U.S. mortgage market that began in 2022 and continued throughout 2023 and 2024.

Establishment of Individual Non-Financial Strategic Goals

Non-financial strategic goals have proven to be an effective tool for motivating our executives to execute on our key strategic initiatives. Through our conversations with shareholders, we understand the importance of clearly linking these non-financial goals to our business strategy and the creation of long-term shareholder value. Individual non-financial objectives for our NEOs are developed in the first quarter of each year in connection with the preparation of our business plan and overall strategy. These individual objectives are specific to each NEO but also intended to support our enterprise-wide initiatives. The 2024 non-financial performance objectives for our NEOs were developed in alignment with our enterprise-wide strategic priorities, tailored to each NEO’s individual role and responsibilities.

These individual non-financial strategic goals are considered management business objectives (MBOs) and evaluated along with an executive’s other MBOs to ultimately determine the 20% portion of that executive’s AIP opportunity based on non-financial individual goals. Consistent with investor feedback, our CEO’s 2024 AIP payout was based entirely on financial performance metrics, although he was still responsible for meeting individual strategic non-financial goals.

Evolution of AIP Goals Related to Responsible Business Priorities

As described above, we have identified a set of responsible business priorities that are aligned with our corporate strategy. By aligning our responsible business practices with our corporate strategy, we remain focused on the areas that are most relevant to our business, which drives the creation of shareholder value while at the same time positioning the Company for long-term sustainability.

Since 2018, our AIP has incorporated non-financial goals that relate to our Equifax responsible business practices. We began by adding a cybersecurity performance measure as an AIP metric in 2018, in order to promote a Company-wide focus on data security and reinforce our overall security program goals. Today, Equifax employees who participate in the AIP have a mandatory security-focused performance goal as part of their individual objectives, which is designed to support the highest level of performance under our global cybersecurity awareness program. Employees are required to identify one or more predetermined security goals, established by the Security Department, that are most appropriate to their role and scope of responsibility.

Over the past several years, we have continued to monitor the evolution of non-financial strategic goals in compensation programs. In recent years, we have expanded our use of non-financial goals in the AIP to include other responsible business practices tied to pre-determined individual performance objectives that align with our strategic priorities.

Evaluation of Individual NEO Performance

Following the end of each year, the CEO evaluates the performance of the other NEOs, taking into account performance for the just-completed year versus predefined commitments for such year, as well as any unforeseen financial, operational and strategic issues and any other relevant information. These performance evaluations are subject to the review of the Compensation Committee. For 2024, the payout levels for the non-financial MBO portion of the AIP (20% weighting) were set at 0% to 200% of target.

The Compensation Committee evaluates the performance of the CEO in a similar manner, with input from the full Board. In connection with the amendment of our CEO’s employment agreement in February 2021, the Compensation Committee determined that Mr. Begor’s future AIP awards would be determined based exclusively on achievement measured against Company financial goals (rather than 80% financial goals and 20% individual objectives). The Committee set non-financial performance objectives for Mr. Begor for 2024; however, Mr. Begor’s performance against those objectives did not impact his 2024 incentive payout.

Summary of 2024 Annual Cash Incentive Awards

In February 2025, the Compensation Committee reviewed each NEO’s performance against the pre-established 2024 performance goals as approved by the Committee. Awards could range from 0% of the executive’s award goal (for performance below the threshold level) to 200% of the individual’s award target (for performance at or above the maximum level). The award paid to our CEO under the 2024 AIP was based exclusively on achievement measured against specified financial goals. Awards paid to our other NEOs under the 2024 AIP were determined based on achievement measured against specified financial goals (80% weighting) and non-financial MBOs (20% weighting). The target and maximum incentives, along with a summary of the actual 2024 awards earned by the NEOs, are set forth in the table that follows. A detailed description of how each NEO’s 2024 incentive award was achieved follows the table.

Although we achieved record revenue in 2024, our financial performance fell short of our enterprise targets due to the continued challenging U.S. macroeconomic environment, including the mortgage market, with U.S. mortgage inquiries down 10% compared to 2023. As a result, the payout to our CEO, whose AIP award is tied 100% to enterprise financial results, was below target. Payouts to our other NEOs under the 2024 AIP were 107.2% of target, on average.

2024 Long-Term Equity Incentive Compensation

Overview

For our CEO and other NEOs, LTI is the largest element of their total compensation package. In determining the value of long-term incentive awards to executive officers other than the CEO, the Committee considers numerous factors including the benchmarking data described on page 61, individual performance, internal equity, importance of role and share run rate (a measure of actual equity-grant activity in relation to the total number of shares outstanding at the Company).

In February 2024, the Committee approved a 2024 Annual LTI structure for our NEOs other than the CEO consisting of TSR performance shares (weighted 25%), Adjusted EBITDA performance shares (weighted 25%), market-priced stock options with a ten-year term (weighted 25%) and time-based RSUs (weighted 25%). The 2024 Annual LTI award mix for our CEO is set forth in his employment agreement and consists of TSR performance shares (weighted 30%), Adjusted EBITDA performance shares (weighted 30%), premium-priced stock options (weighted 20%) and time-based RSUs (weighted 20%).

The 2024 Annual LTI framework for our NEOs (including our CEO) remained consistent with the 2023 LTI award mix.

2024 Annual LTI Structure
| ⏺ TSR performance shares: value based on the performance of our stock relative to companies in the S&P 500 Index over a three-year period; subject to post-vesting holding period of 12 months ⏺ Adjusted EBITDA performance shares: value based on our Adjusted EBITDA performance during a three-year period; subject to post-vesting holding period of 12 months ⏺ Premium-priced stock options: granted to our CEO, cliff vest on the third anniversary of the grant date and have exercise prices set at a premium to the market value of our stock on the grant date ⏺ Market-priced stock options: granted to our other NEOs, vest ratably over three years and have an exercise price set at the market value of our stock on the grant date ⏺ Time-based RSUs: accomplish retention objectives through a three-year cliff vesting schedule while also augmenting the alignment of management and shareholder interests |

A detailed description of each element of our 2024 Annual LTI program follows.

2024 LTIP Elements

Performance shares are granted based on two different metrics: TSR and Adjusted EBITDA.

TSR Performance Shares

TSR performance shares align with shareholder interests, as higher relative TSR results in higher returns for shareholders compared to other investment options. TSR performance shares are earned, if at all, based on the percentile ranking of the Company’s cumulative TSR compared to the TSR of the companies in the S&P 500 Index (as constituted on the initial grant date, subject to certain adjustments) after a three-year performance period.

As described on page 61, our compensation peer group is composed of companies with which we compete for business and talent. While the Committee recognizes this as a valuable peer group for evaluating compensation, the stock performance of the companies in our compensation peer group is not necessarily impacted by the same economic factors as ours. Moreover, investors are likely to compare Equifax to other companies in the S&P 500 Index (of which we are a member). For this reason, the Committee believes that the broader peer group of the S&P 500 Index is more appropriate for evaluating our relative TSR performance for purposes of performance shares issued under our LTI plan.

​

​ | ​
72 | 2025 Proxy Statement

​

Table of Contents

Payouts in February 2027 (if any) for the TSR performance shares awarded on February 9, 2024 will be based on the following scale, with straight-line interpolation between the threshold and maximum levels:

TSR Performance Shares: Performance/Payout Scale

​ | ​ | ​ | ​
Company TSR |  | Performance Share Payout as a
Percentile | ​ | % of Target
75th |  | 200 | %
50th |  | 100 | %
25th |  | 50 | %
Below 25th |  | 0 | %

The number of TSR performance shares payable is the target award multiplied by a percentage (from 0% to 200%), calculated by taking an average of the payout percentages achieved for each of the last four quarters of the performance period based on the Company’s cumulative TSR percentile ranking through the end of each such quarter. Basing the award payout on the average of the payout percentages for each of the last four quarters of the three-year performance period counterbalances potential late performance period volatility.

If our team does not deliver cumulative TSR that ranks at or above the 25th percentile, the value of the TSR performance shares will be $0. In addition, in the event our cumulative TSR is negative over the three-year performance period, the payout is capped at 100% of the target shares, irrespective of our TSR percentile rank versus the S&P 500.

TSR performance share awards accrue dividend equivalents on earned shares and require the recipient to hold the shares for a period of 12 months following vesting.

Adjusted EBITDA Performance Shares

Adjusted EBITDA performance shares tie our executive compensation payouts to a key internal operational performance metric that measures management’s ability to drive profitable growth.

Adjusted EBITDA performance shares granted in 2024 are earned, if at all, based on our Adjusted EBITDA for each of the three years of the performance period. In February 2024, the Committee set the threshold, target and maximum Adjusted EBITDA levels for 2024, and threshold, target and maximum Adjusted EBITDA growth rate goals for each of 2025 and 2026. The number of Adjusted EBITDA performance shares payable is the target award multiplied by a percentage (from 0% to 200%), calculated by taking an average of the payout percentages achieved for each of the three years of the performance period.

Adjusted EBITDA performance share awards accrue dividend equivalents on earned shares and require the recipient to hold the shares for a period of 12 months following vesting.

Market-Priced Stock Options

The Compensation Committee believes that market-priced stock options provide a strong incentive for the creation of long-term shareholder value, because stock options may be exercised for a profit only to the extent our stock price appreciates after the grant date. If our NEOs are not able to drive share price returns in excess of the exercise price before the expiration date, the realized value of their 2024 stock options will be $0.

The exercise price of stock options granted in 2024 for our NEOs other than the CEO were set at the market value of our stock on the grant date. The market-priced stock options granted on February 9, 2024 vest in equal installments on the first, second and third anniversaries of the grant date, assuming continued employment with the Company, and have a ten-year term.

Premium-Priced Stock Options

Premium-priced stock options granted to our CEO tighten the link between our long-term incentive compensation and the creation of shareholder value by ensuring that our CEO receives gains only after a premium return is delivered to investors.

The exercise prices of stock options granted in 2024 for our CEO were set above the market value of our stock in two equally weighted tranches, with exercise prices of 110% and 120% of the market value of our stock on the grant date. The premium-priced stock options granted on February 9, 2024 cliff-vest on the third anniversary of the grant date, assuming continued employment with the Company, and have a seven-year term.

RSUs

We use RSUs to encourage retention of our employees over the long-term and simultaneously inspire our team to focus on corporate performance. The RSUs issued to our NEOs on February 9, 2024 cliff vest on the third anniversary of the grant date, thereby maximizing the award’s long-term retention value. The value of RSUs varies directly with the market price of our common stock, which creates an added incentive to make decisions that will build shareholder value over the long term. RSUs accrue dividend equivalent units on earned shares.

Target Grant Value for 2024 Annual LTI Awards

The following table details the target grant value used by the Compensation Committee to determine the number of performance shares, stock options and RSUs granted to each NEO in 2024. Actual grant date values, computed in accordance with applicable accounting standards, are disclosed in the “2024 Grants of Plan-Based Awards” table on page 86. The actual value of equity awards that may be realized by the NEOs will depend on their continued service, our Adjusted EBITDA growth and our future stock price performance.

The Committee approved a 2024 Annual LTI award mix for our CEO that included TSR performance shares (weighted 30%), Adjusted EBITDA performance shares (weighted 30%), premium-priced stock options with a seven-year term (weighted 20%) and time-based RSUs (weighted 20%). The Committee approved a 2024 Annual LTI award mix for our NEOs other than the CEO that included TSR performance shares (weighted 25%), Adjusted EBITDA performance shares (weighted 25%), market-priced stock options with a ten-year term (weighted 25%) and time-based RSUs (weighted 25%).

1 | Except as otherwise noted, the grant date for annual equity awards to each of the NEOs was February 9, 2024; the closing stock price on such date was $249.18.

2 | The Compensation Committee determined the 2024 long-term incentive awards by establishing a dollar value for each NEO and then converting this dollar value to a number of performance shares, stock options (either market- or premium-priced) and RSUs.

3 | The number of TSR performance shares granted is calculated by taking the target grant value divided by the closing price of our common stock on the grant date, then applying an illiquidity discount to reflect the 12-month post-vesting holding period.

4 | The number of Adjusted EBITDA performance shares granted is calculated by taking the target grant value divided by the closing price of our common stock on the grant date, then applying an illiquidity discount to reflect the 12-month post-vesting holding period.

5 | Premium-priced stock options were granted to our CEO in 2024 and market-priced stock options were granted to our other NEOs. The premium-priced stock options were granted in two equally-weighted tranches, with exercise prices of 110% and 120% of the grant date closing stock price. The number of premium-priced stock options granted is calculated using a Monte Carlo model, which is built on a lattice model framework. The number of market-priced stock options granted is calculated based on a binomial valuation model.

6 | The number of RSUs granted is calculated by taking the target grant value divided by the closing price of our common stock on the grant date.

7 | The grant date for the annual equity award to Mr. Borton, who joined the Company on May 6, 2024, was May 6, 2024; the closing stock price on such date was $231.34.

8 | Mr. Farshchi received an annual equity award of $1,700,000 on February 9, 2024 in his capacity as Chief Information Security Officer. He received an additional annual equity grant of $800,000 on February 20, 2024 upon his appointment as Chief Technology Officer in recognition of his increased responsibilities and a review of competitive market rates for his new position; the closing stock price on such date was $257.85.

2024 Borton New Hire Award

In connection with his hiring as Executive Vice President, President, Workforce Solutions, and to compensate him for foregoing unvested equity previously granted at his prior employer, in addition to the 2024 annual LTI award, on May 6, 2024, Mr. Borton received a new hire “make whole” grant of RSUs, TSR performance shares and Adjusted EBITDA performance shares with an aggregate grant date fair value of $6.2 million. His new hire RSU award (comprising $3 million in value) vests in three equal increments beginning on the first anniversary of the grant date. His new hire TSR and Adjusted EBITDA performance share awards (comprising $3.2 million in aggregate value) vest at the end of a three-year performance period. As described above under “2024 LTIP Elements,” RSU and TSR performance share awards accrue dividend equivalents on earned shares; TSR and Adjusted EBITDA performance shares require the recipient to hold the shares for a period of 12 months following vesting.

CEO Equity Deferrals

As a result of his voluntary, irrevocable deferral elections, our CEO will continue to be invested in Equifax for more than ten years following his tenure at the Company.

| ● | During the past four years, our CEO has made proactive irrevocable elections under our deferred compensation program to defer 100% of his long-term incentives granted in the form of RSUs and performance shares.

| ● | These deferred equity awards had an aggregate value of more than $61 million as of March 7, 2025 (assuming payout at 100% of target for his outstanding awards), are payable only in Equifax common stock if earned and are not payable until after Mr. Begor leaves the Company.

| ● | Deferred awards granted in 2021 begin paying out in equal annual installments over a 10-year period, beginning five years following Mr. Begor’s departure from Equifax.

| ● | Deferred awards granted in 2022 through 2024 begin paying out in equal annual installments over a 10-year period, beginning seven months following Mr. Begor’s departure from Equifax.

| ● | These deferral decisions reflect our CEO’s belief in the shareholder value to be delivered by executing on our strategic priorities and building on the strong foundation of the Equifax Cloud to accelerate innovation, new products, EFX.AI capabilities and growth.

Vesting Results of Previously-Granted Performance Shares

2022 TSR Performance Share Awards

In February 2025, the Compensation Committee approved the vesting and payment of the TSR performance shares granted in February 2022 at 68.61% of the target award level. The Committee’s determination was based on the Company’s achievement of total shareholder return relative to companies in the S&P 500 Index (as constituted on the initial grant date, subject to certain adjustments) over the three-year performance period ended December 31, 2024. The number of TSR performance shares payable was the target award multiplied by a percentage (from 0% to 200%) that was calculated by taking the average of the payout percentages achieved through each of the last four quarters of the performance period, based upon the Company’s cumulative TSR percentile ranking through the end of each such quarter, as shown in the table below:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Period from January 1, 2022 through the end of:

2022 Adjusted EBITDA Performance Share Awards

In February 2025, the Compensation Committee approved the vesting and payment of the Adjusted EBITDA performance shares granted in February 2022 at 61.7% of the target award level. The Committee’s determination was based on our Adjusted EBITDA for each of the three years of the performance period ended December 31, 2024. The number of Adjusted EBITDA performance shares payable was the target award multiplied by a percentage (from 0% to 200%) that was calculated by taking the average of the payout percentages achieved for each of the three years of the performance period, as shown in the table below:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | Actual | ​ | Actual Payout
Performance Period |  | Threshold (50%) |  | Target (100%) |  | Maximum (200%) |  | Performance |  | as a % of Target
Year 1 | 2022 |  | $1.671 billion |  | $1.893 billion |  | $ 1.963 billion |  | $1,721,798 |  | 61.5%
Year 2 | 2023 |  | $1.722 billion (prior year actual) |  | $1.851 billion (+7.5% from prior year actual) |  | $1.911 billion (+11% from prior year actual) |  | $1,694,748 |  | 0%
Year 3 | 2024 | ​ | $1.695 billion (prior year actual) |  | $1.822 billion (+7.5% from prior year actual) |  | $1.881 billion (+11% from prior year actual) | ​ | $1,836,067 | ​ | 123.7%
Final 3-Year Average Payout Percentage |  | 61.7%

Actions Taken with Respect to 2025 Compensation

Based on a 91% approval of our compensation program at the 2024 Annual Meeting and direct engagement with approximately 65% of our shareholder base since that time, our investors have expressed support for our overall compensation strategy.

In February 2025, after conducting a thoughtful review and considering shareholder feedback as described above, the Committee determined the key elements of our 2025 executive compensation program. Based on the high level of shareholder support for our core compensation program, the Committee determined that no changes to the structure of the compensation program were necessary in 2025 compared to 2024.

The Compensation Committee will continue to monitor our executive compensation program to ensure that it is consistent with the Company’s objectives, provides appropriate incentives to management, and remains competitive with other companies in the industries in which we operate and compete for executive talent.

Other Compensation Program Information

Equity Award Grant Practices

We have a written policy on equity grants, including stock options, designed to formalize our equity grant practices and ensure that equity awards will be made on specified dates. The Compensation Committee reviews and approves annual equity-based awards to senior executives who are direct reports to the CEO or reporting officers under Section 16 of the Exchange Act in the first calendar quarter of each year (around the time of their annual performance reviews). In accordance with our policy and shareholder-approved 2023 Omnibus Incentive Plan (which replaced our 2008 Omnibus Incentive Plan effective May 4, 2023), the Committee has delegated specific authority to the CEO to approve grants (within specified limits) to non-executive officers and other eligible employees. We may make equity awards at other times during the year for new hires or for other reasons, such as a job promotion or as a result of an acquisition. The Compensation Committee reviews equity grants made pursuant to the CEO’s delegated authority, if any, on a quarterly basis.

The Compensation Committee does not take material nonpublic information into account when determining the timing and terms of equity awards and the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. We generally schedule Board and Committee meetings at least a year in advance and, as noted above, make annual equity awards to our NEOs at around the same time every year.

As required by Item 402(x) of the Securities Exchange Act of 1934, the following table presents information regarding stock options issued to our NEOs in 2024 during any period beginning four business days before the filing of Form 10-K or Form 10-Q, or the filing or furnishing of a Form 8-K that discloses material nonpublic information (other than a Form 8-K disclosing a material new option grant under Item 5.02(e)), and ending one business day after the filing or furnishing of such report with the SEC.

Retirement and Other Benefits

Our NEOs receive retirement, deferred compensation and other benefits that are designed to be part of a competitive package to attract and retain executive talent. We maintain the following retirement, deferred compensation and other benefit plans, in which all or some of our NEOs participate:

401(k) Plan

The 401(k) Plan is a tax-qualified defined contribution plan that permits eligible employees (including NEOs) to defer a portion of their compensation and receive Company matching contributions.

Supplemental Retirement Plan

The Supplemental Retirement Plan for Executives of Equifax Inc. (the “SERP”) covers certain of our NEOs (Messrs. Gamble and Ploder) as well as certain senior executive officers designated by the Compensation Committee. The SERP provides monthly supplemental retirement benefits after retirement. The SERP was closed to new participants after January 1, 2016.

Supplemental Contribution Program

In 2016, we amended the Executive Deferred Compensation Plan to establish a supplemental retirement contribution program (the “Supplemental Contribution Program”) for senior executive officers designated by the Compensation Committee who are not eligible to participate in the SERP. The Supplemental Contribution Program provides for an annual contribution equal to 10% of the sum of the eligible executive’s base salary paid and cash incentive earned for the year. Messrs. Begor, Borton, Horvath and Farshchi participate in the Supplemental Contribution Program. Messrs. Gamble and Ploder participate in the SERP and are not eligible to participate in the Supplemental Contribution Program.

Deferred Compensation Plans

The NEOs and other executives are eligible to participate in the Company’s non-qualified deferred compensation plans. These plans allow participants to elect to defer cash compensation and receipt of shares of Company stock on vesting of RSU and performance share awards. Deferred amounts are payable upon the executive’s retirement or other termination of employment. See pages 94-96 for more information on our deferred compensation plans.

During the past four years, our CEO has made proactive, irrevocable elections under our deferred compensation program to defer 100% of his long-term incentives granted in the form of RSUs and performance shares. These deferred equity awards had an aggregate value of more than $61 million as of March 7, 2025 (assuming payout at 100% of target for his outstanding awards), are payable only in Equifax common stock if earned and are not payable until after Mr. Begor leaves the Company. As a result of his deferral elections, our CEO will continue to be invested in Equifax for more than ten years following his tenure at the Company. See page 75 for more information.

Other Benefits

We provide our NEOs with benefits generally available to our U.S. employees, including participation in our employee stock purchase program and medical, dental, vision, life insurance and disability insurance benefits.

Limited Perquisites

We offer limited perquisites to our executive officers. Perquisites for our executives have the following objectives:

| ● | maximizing the value of Company-provided compensation through provision of a financial planning and tax services allowance in an annual amount of up to $50,000 for the CEO and $10,000 for other NEOs ($12,500 in their first year for newly-hired and newly-promoted executives);

| ● | supporting executives’ continued health and ability to render services to the Company through an annual physical program;

| ● | to allow the CEO’s travel time to be used productively, providing the CEO with private aircraft usage for personal purposes, up to an annual limit of $200,000 in 2024; and

| ● | providing monthly relocation living allowances under certain circumstances, as approved by the Compensation Committee.

The attributed costs of perquisites are included in the “All Other Compensation” column of the Summary Compensation Table on page 83 and Note 7 thereto. We do not provide tax reimbursement on the value of the applicable perquisite other than certain relocation and foreign tax expenses.

CEO Employment Agreement

On November 7, 2024, the Company entered into a letter agreement (the “2024 Letter Agreement”) with our CEO which amends certain terms of the employment agreement between the Company and Mr. Begor dated March 27, 2018 (as amended by the letter agreement between the Company and Mr. Begor dated February 4, 2021 and the 2024 Letter Agreement, the “Employment Agreement”).

Under the Employment Agreement, Mr. Begor’s annual base salary is $1.5 million, subject to increase but not decrease, by the Board or the Compensation Committee. Mr. Begor’s target annual cash incentive award opportunity is 120%, subject to increase but not decrease, of his annual base salary and is determined exclusively based upon achievement measured against specified Company financial goals.

Under the Employment Agreement, Mr. Begor’s long-term incentive award target grant date value is $10.1 million, subject to increase but not decrease. The components of Mr. Begor’s annual long-term incentive award consist of (i) 60% performance shares, (ii) 20% premium-priced stock options and (iii) 20% time-based RSUs. Each award of premium-priced options will be split evenly into two equally-weighted tranches, based on fair value on the grant date, with exercise prices set at premiums of 110% and 120% to the fair market value of a share of our common stock on the applicable grant date.

As a result of the above, 80% of Mr. Begor’s annual long-term incentive award is subject to substantive performance requirements and only 20% being subject to time-based vesting. Mr. Begor’s annual long-term incentive awards are subject to the Company’s enhanced clawback policy whereby the Board may recover incentive compensation awarded to employees in the event of misconduct or failure of oversight that results in significant financial or reputational harm, irrespective of whether there has been a financial restatement.

Mr. Begor participates in the Company’s incentive, savings, retirement and welfare benefit plans and programs made available to senior executives. The Employment Agreement provides for perquisites that include an annual physical and a financial planning allowance. These perquisites serve the important business purposes of ensuring that our CEO is aware of his personal health and receives adequate assistance in managing his personal finances, each of which enables him to focus his time on managing our business.

If Mr. Begor is (i) terminated by the Company without “cause,” (ii) resigns for “good reason” or (iii) on or after December 31, 2027, voluntarily terminates his employment (each as defined in the Employment Agreement), provided he signs a release of claims against the Company and complies with applicable restrictive covenants, any then outstanding equity awards will vest in accordance with the applicable award agreement.

If Mr. Begor is terminated by the Company without cause (other than due to disability or death) or resigns for good reason within the period six months prior to and two years after a “change in control” (as defined in the Employment Agreement), he will be entitled to receive, provided he signs a release of claims against the Company and complies with applicable restrictive covenants, (i) a lump sum payment equal to three times the sum of (x) his annual base salary and (y) his target annual incentive opportunity for the year of termination, (ii) any accrued but unpaid annual incentive plus a pro rata annual incentive for the year of termination, (iii) full vesting of any outstanding equity awards (subject, in the case of performance-based awards, to the determination of achievement of the performance measures in accordance with the applicable award agreement and incentive plan) and (iv) access to the Company’s health plan for two years or the lesser period permitted by the Company’s general benefits plans and applicable law and monthly payments of or an amount equal to premiums for continuation of healthcare coverage under Section 4980B of the Internal Revenue Code (“Code”) or comparable law (“COBRA”) for 24 months.

Mr. Begor is required to own and hold Company stock having a value equal to six times his annual base salary.

The Employment Agreement contains confidentiality, non-competition and non-solicitation restrictions during the term of the Employment Agreement and for certain specified periods thereafter, that are comparable to the restrictions applicable to other senior executives.

Except for Mr. Begor’s Employment Agreement, employment agreements are not used with respect to any other executive officer, each of whom is employed on an “at will” basis.

Change in Control Arrangements

The Equifax Inc. 2019 Change in Control Severance Plan (the “CIC Plan”) applies to each of our NEOs and senior executives, except our CEO. The severance benefits applicable to Mr. Begor in the event of a change of control are contained in his employment agreement with the Company, as described above. See “Change in Control Severance Plan” on pages 101-102 for more information on the CIC Plan.

Subject to the discretion of the Compensation Committee, under our 2008 Omnibus Incentive Plan and 2023 Omnibus Incentive Plan (which replaced the 2008 Omnibus Incentive Plan effective May 4, 2023) and applicable award agreements, equity awards granted to our NEOs include a “double-trigger” change in control provision to limit accelerated vesting in the event of a change in control of Equifax to those situations where an executive is terminated without cause, the executive terminates for good reason or the acquirer fails to assume the awards.

Consideration of Certain Tax Effects

The Company’s annual tax deduction for compensation paid to each of the NEOs and certain other current or former officers who are subject to the compensation limits of Code Section 162(m) is capped at $1 million. The Compensation Committee considers these implications, including the potential lack of deductibility under Section 162(m), among several factors when making compensation decisions, but the Compensation Committee has provided and reserves the right to provide compensation that does not qualify as deductible under Section 162(m).

Management of Compensation-Related Risk

In establishing and reviewing the Company’s executive compensation program, the Compensation Committee annually considers whether the program encourages unnecessary or excessive risk-taking and has concluded that it does not. The Committee reviewed our material compensation programs and noted numerous ways in which risk is effectively managed or mitigated. This evaluation for 2024, which was conducted with the assistance of management and the Committee’s independent compensation consultant (FW Cook), covered a wide range of practices and policies. All plans were deemed to have substantial risk mitigators which, in the most material incentive plans, include a balanced mix of fixed and variable pay and short and long-term incentives; use of multiple performance measures including corporate, business unit and individual performance weightings in incentive plans; a portfolio of long-term equity incentives including time-based and performance-based measures; caps, discretion in payment, decelerators, clawbacks, oversight by non-plan participants, significant stock ownership guidelines, pre-approval requirements for executive stock transactions; and the existence of policies prohibiting Company stock hedging and pledging and requiring executive incentive compensation recoupment in specified circumstances.

The Compensation Committee has also reviewed the Company’s overall enterprise risks and how compensation programs for employees generally impacted individual behavior that could exacerbate these enterprise risks. Board and management processes are in place to oversee risk associated with global compensation programs and practices, including, but not limited to, regular business reviews; alignment of compensation plan goals with our annual and long-term strategic goals and performance expectations; review of enterprise risk management by the Board as part of the annual strategy and budget reviews; and other appropriate internal controls. The Committee concluded that the Company’s compensation plans, programs and policies, considered as a whole, including applicable risk-mitigation features, are not reasonably likely to have a material adverse effect on the Company.

Policies on Clawback of Incentive Compensation

We have a clawback policy that covers all employees, including executive officers, and applies to equity awards and other incentive compensation awarded to such employees. The Compensation Committee has discretion to apply the policy to recover and recoup incentive compensation in all of the events described below:

| ​ |  | ​ |
Events that Trigger Action |  | Covered Persons |  | Covered Awards
Material restatement with misconduct | ​ | Current and former employees | ​ | Annual and long-term incentives awarded within three-year period preceding the date the misconduct is discovered
Material restatement without misconduct | ​ | Current and former executives | ​ | Excess amount of annual and long-term incentives awarded within three-year period preceding the restatement date
Materially inaccurate financial statements or performance metrics with misconduct | ​ | Current and former employees | ​ | Annual and long-term incentives awarded within three-year period preceding the date the misconduct is discovered
Materially inaccurate financial statements or performance metrics without misconduct | ​ | Current and former employees | ​ | Excess amount of annual and long-term incentives awarded within three-year period preceding the date the inaccuracy is discovered
Misconduct resulting in significant financial and/or reputational harm and the employee either engaged in the misconduct or failed to fulfill his or her supervisory responsibility to prevent another employee from engaging in such misconduct | ​ | Current and former employees | ​ | Annual and long-term incentives awarded within three-year period preceding the date the misconduct is discovered

The policy also provides that the Company will disclose its decision to take action, the number of employees impacted and their seniority, and the aggregate amount of the clawback/forfeiture if the underlying circumstances of the misconduct are publicly disclosed. The policy provides that the Committee may limit or eliminate disclosure if the events are not publicly disclosed or if disclosure would be likely to result in or exacerbate any litigation or other proceeding against the Company or its officers or directors, violate applicable law with respect to privacy, violate legal privilege or breach a contractual obligation.

Under the terms of award agreements issued under our 2008 Omnibus Incentive Plan and our 2023 Omnibus Incentive Plan (which replaced the 2008 Omnibus Incentive Plan effective May 4, 2023), employees, including our NEOs, who violate the agreement’s non-compete, non-solicitation and non-disclosure restrictions or who engage in certain other activities detrimental to the Company may be subject to financial consequences, including cancellation of their outstanding equity awards or recovery by the Company of all gains from exercised stock options and vested shares received during the period beginning six months prior to the date of the violation. In addition, these recovery means are also applicable to the incentive equity awards of any employee who is terminated for cause, as determined in the sole discretion of the Committee.

We also have a clawback policy that complies with SEC rules and NYSE listing standards related to clawbacks.

Stock Ownership Requirements

The Compensation Committee recognizes the critical role that executive stock ownership has in aligning the interests of management with those of shareholders. As such, we maintain a formal stock ownership policy, under which our CEO and our other senior executives are required to acquire and hold Equifax common stock with a market value of six times base salary and three times base salary, respectively, within five years of assuming their respective positions. As of the most recent annual measurement date, all of our executive officers were in compliance with our stock ownership requirements.

Insider Trading Policy

We have an insider trading policy that governs the purchase, sale and other disposition of our securities by our directors, officers and employees. We believe this policy is reasonably designed to promote compliance with insider trading laws, rules and regulations and listing standards applicable to the Company. In addition, it is our policy to comply with applicable securities and state laws, including insider trading laws, when engaging in transactions in our securities.

Mandatory Trading Plans for Senior Executives

Our insider trading policy also prohibits our CEO and other senior executives from purchasing or selling Equifax securities except pursuant to a Rule 10b5-1 trading plan in a form that has been approved by the Office of Corporate Secretary.

Hedging and Pledging Policies

Under our insider trading policy, our employees, officers and directors are prohibited from purchasing or selling financial instruments (including prepaid variable forward contracts, equity swaps, collars, exchange funds and other derivative securities), or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Equifax securities. We also prohibit our directors, officers and employees from holding our stock in a margin account or pledging our stock as collateral for a loan.

Compensation Committee Interlocks and Insider Participation

Tom Hough, Mark Feidler, Rob Marcus and Melissa Smith were members of the Compensation Committee during 2024. None of these individuals is or has been an executive officer of the Company, or had any relationship requiring disclosure by the Company under the SEC’s rules requiring disclosure of certain relationships and related party transactions. None of the Company’s executive officers served as a director or a member of a compensation committee (or other committee serving an equivalent function) of any other entity, the executive officers of which served as a director of the Company or a member of the Compensation Committee during 2024.

1 | Salary represents base salary paid to each of the NEOs for each year shown. Amounts shown are not reduced to reflect the individuals’ election, if any, to defer receipt of salary under the Equifax 2005 Executive Deferred Compensation Plan or the Equifax Inc. Employee Deferred Compensation Plan (2022). For Mr. Ploder, this amount also includes a payment of $72,116 for unused vacation paid upon retirement.

2 | The grant date for annual equity awards to each of the NEOs except Chad Borton was February 9, 2024; the closing stock price on such date was $249.18. The grant date for the annual equity award to Mr. Borton was his new hire date of May 6, 2024; the closing stock price on such date was $231.34. Mr. Farshchi received an annual equity award on February 9, 2024 in his capacity as Chief Information Security Officer and an additional grant on February 20, 2024 to recognize his promotion to Chief Technology Officer; the closing stock price on such date was $257.85.

3 | For each NEO, the amounts in this column represent the aggregate grant date fair value computed in accordance with FASB ASC Topic 718 without regard to estimated forfeitures related to service-based vesting conditions. Amounts shown are not reduced to reflect the individuals’ election, if any, to defer receipt of stock awards under the Equifax Director and Executive Stock Deferral Plan or the Equifax Inc. Employee Deferred Compensation Plan (2022). Stock awards in 2024 included time-vested RSUs, TSR performance shares and Adjusted EBITDA performance shares. For the 2024 TSR performance share awards, the grant date fair value was determined using a Monte Carlo valuation model consistent with the estimated full cost to be recognized over the three-year performance period based on the probable outcome of the performance conditions, then applying an illiquidity discount to reflect the 12-month post-vesting holding period.

The calculations reflect an accounting value for the 2024 TSR performance share grants to our NEOs other than Mr. Borton of $295.83 per share, which was 118.72% of our closing stock price on the February 9, 2024 grant date. Mr. Farshchi received an additional grant on February 20, 2024 in connection with his promotion to Chief Technology Officer; the calculations for his promotion grant reflect an accounting value for the 2024 TSR performance share grants of $306.12 per share, which was 118.72% of our closing stock price on the grant date. For Mr. Borton, who joined the Company on May 6, 2024, the calculations reflect an accounting value for the 2024 TSR performance share grants of $235.16 per share, which was 101.65% of our closing stock price on the May 6, 2024 grant date. Assumptions used in the calculation of the amounts in this column are described in Note 8 to our audited consolidated financial statements for the fiscal year ended December 31, 2024, in our 2024 Form 10-K.

For the 2024 Adjusted EBITDA performance share awards, the grant date fair value was determined based on our closing stock price on the grant date, then applying an illiquidity discount to reflect the 12-month post-vesting holding period. The calculations reflect an accounting value for the 2024 Adjusted EBITDA performance share grants to our NEOs other than Mr. Borton of $227.75 per share for the awards, which was 91.4% of our closing stock price of $249.18 on the February 9, 2024 grant date. Mr. Farshchi received an additional grant on February 20, 2024 in connection with his promotion to Chief Technology Officer; the calculations for his promotion grant reflect an accounting value for the 2024 Adjusted EBITDA performance share grants of $235.67 per share,

which was 91.4% of our closing stock price on the grant date. For Mr. Borton, the calculations reflect an accounting value for the 2024 Adjusted EBITDA performance share grant of $210.08, which was 90.8% of closing price on the May 6, 2024 grant date.

The value of the 2024 time-vested RSU awards, TSR performance share awards and Adjusted EBITDA performance share awards, based on the closing price of our common stock on the grant date and assuming the highest level of performance under the performance share awards would be achieved (200% of the target), are as follows: Mr. Begor, $15,281,462; Mr. Gamble, $5,376,806; Mr. Borton, $14,606,114; Mr. Horvath, $4,704,518; Mr. Farshchi, $3,361,728; and Mr. Ploder, $4,704,518. The NEOs may never realize any value from the performance shares, and to the extent they do, the amounts realized may have no correlation to the amounts reported above.

4 | The amount in this column shows the aggregate grant date fair value of stock options computed in accordance with FASB ASC Topic 718. For NEOs (excluding Mr. Begor), the amount is based on the fair value of the stock option award as estimated using the binomial model multiplied by the number of shares subject to the option award. For Mr. Begor, who received premium priced stock option awards, the amount is based on the fair value of the stock option award as estimated using the Monte Carlo model multiplied by the number of shares subject to the option award. Assumptions used in the binomial and Monte Carlo models for calculation of the amounts in this column are described in Note 8 to our audited consolidated financial statements for the fiscal year ended December 31, 2024, in our 2024 Form 10-K.

5 | Represents annual incentive awards paid under the Annual Incentive Plan for services performed in 2024, 2023 and 2022, respectively. Amounts shown are not reduced to reflect the NEO’s election, if any, to defer receipt of awards under the Equifax 2005 Executive Deferred Compensation Plan or the Equifax Inc. Employee Deferred Compensation Plan (2022).

6 | For Messrs. Gamble and Ploder, the amounts in this column reflect the aggregate increase (or decrease), if any, of accumulated pension benefit accruals at the earliest unreduced retirement age for such NEOs under the SERP in the applicable fiscal year. For Mr. Ploder, amounts also reflect accruals under the Equifax Inc. U.S. Retirement Income Plan (“USRIP”). There are no above-market or preferential earnings on compensation deferred on a basis that is not tax-qualified, including such earnings on non-qualified contribution plans. The pension accrual amounts represent the difference in present value liability (measured at the respective fiscal year-end dates shown in the table) based on the assumptions shown in the text following the “Pension Benefits at 2024 Fiscal Year-End” table on page 92. Year-over-year changes in pension value generally are driven in large part by changes in actuarial pension assumptions as well as increases in service, age and compensation. The increase in pension values for Mr. Gamble is due to one additional year of service under the SERP offset partially by an increase in the discount rate. The decrease in pension values for Mr. Ploder is due to an increase in the discount rate as well as Mr. Ploder’s post-retirement benefit selection, which has a lesser value than our pre-retirement benefit assumptions. The decrease in value more than offsets the value of an additional year of service. See “Pension Benefits at 2024 Fiscal Year-End” on page 92 for more information on pension benefits.

| a | The amounts in this column are based on the aggregate incremental cost to the Company, if any, with respect to tax and financial planning services, annual medical examinations, event tickets and private aircraft usage, none of which exceeded $25,000 as a category for any NEO except for Mr. Begor, whose total includes $50,000 for tax and financial planning services and $183,342 for private aircraft usage.

| b | The amounts for Messrs. Borton and Horvath reflect reimbursement for relocation and/or temporary living expenses associated with their Company-required moves.

| c | The Company does not provide any additional tax reimbursements on the value of perquisites and personal benefits received by the NEOs other than those provided to other employees. The Company’s standard policy for employees is to provide a tax gross-up for certain relocation assistance.

| d | For Messrs. Begor, Borton, Horvath and Farshchi, the amounts in this column reflect a Company contribution to the Supplemental Contribution Program (part of the non-qualified deferred compensation plan) for the applicable fiscal year as well as a Company match of 100% of the first 5% of compensation (subject to the government limit on compensation of $345,000 in 2024) contributed on a pre-tax and/or after-tax basis to the tax-qualified 401(k) Plan. For Messrs. Gamble and Ploder, the amounts reflect a Company match of 50% of the first 6% of compensation (subject to the government limit on

| e | Represents imputed income for the cost of $3,000,000 in life insurance coverage. Mr. Ploder has this coverage as a participant in the Equifax Inc. Executive Life and Supplemental Retirement Benefit Plan, which was closed to new participants in 2005. Existing participants at time of closure were grandfathered under the plan. Post-retirement, Mr. Ploder asked the Company to cancel his life insurance policy; the policy was cancelled in January 2025.

8 | The 2022 amounts for Mr. Begor include the July 2022 performance-oriented equity award of TSR performance shares, Adjusted EBITDA performance shares, premium-priced stock options and RSUs, with an aggregated grant date fair value of $25 million. The 2023 amounts for Mr. Horvath include a new hire “make whole” grant of RSUs and TSR performance shares with an aggregated grant date fair value of $4 million. The 2024 amounts for Mr. Borton include a new hire “make whole” grant of RSUs, TSR performance shares and Adjusted EBITDA performance shares with an aggregated grant date fair value of $6.2 million.

| PS-EBITDA (N) = new hire grant of Adjusted EBITDA performance shares; RSUs (N) = new hire grant of time-vested RSUs; PS-TSR (P) = promotion grant of TSR performance shares; PS-EBITDA (P) = promotion grant of Adjusted EBITDA performance shares; RSUs (P) = promotion grant of time-vested RSUs; and MPSOs (P) = promotion grant of market-priced stock options.

2 | The amounts shown represent the range of possible dollar payouts that could have been earned under the 2024 AIP. With respect to Mr. Begor, the amount in the “Threshold” column assumes the Company achieved the minimum performance level required for the granting of AIP awards for each component of the AIP award, resulting in an award equal to 25% of Mr. Begor’s award target. With respect to our other NEOs, the amount in the “Threshold” column assumes the Company achieved the minimum performance level required for the granting of AIP awards for each component of the AIP award, and that the NEO was rated “achieves expectations” for the individual performance portion of the award (100% of target), resulting in an award equal to 40% of each such NEO’s award target.

3 | Represents grants to each NEO during 2024 of performance shares under our 2023 Omnibus Incentive Plan. TSR performance shares granted are earned, if at all, based on our TSR performance after a three-year period relative to the TSR after the same period for the companies in the S&P 500 Index as of the grant date. Adjusted EBITDA performance shares granted are earned, if at all, based on Adjusted EBITDA for each of the three years of the performance period. Performance shares accrue dividend equivalent units which vest at the same time and at the same level of award attainment as the underlying shares. Performance share awards require the recipient to hold the shares for a period of 12 months following vesting. Information regarding performance targets, vesting and additional performance share award details is set forth under “2024 Long-Term Equity Incentive Compensation” beginning on page 72.

4 | Represents the number of RSUs granted to each NEO during 2024. The RSUs will vest, subject to continued employment, on the third anniversary of the grant date, except Mr. Borton’s new hire RSU award, which vests in three equal increments beginning on the first anniversary of the grant date. Dividend equivalents accrue on unvested shares. Additional information regarding RSUs is set forth under the heading “2024 Long-Term Equity Incentive Compensation” beginning on page 72.

5 | For Mr. Begor, represents premium-priced stock options issued with an exercise price equal to 110% or 120% of the closing price of Equifax stock ($249.18) on the February 9, 2024 grant date. For Messrs. Gamble, Horvath, Farshchi and Ploder, represents market-priced stock options issued with an exercise price equal to the closing price of Equifax stock ($249.18) on the February 9, 2024 grant date. For Mr. Borton, represents market-priced stock options issued with an exercise price equal to the closing price of Equifax stock ($231.34) on the May 6, 2024 grant date. For Mr. Farshchi, represents market-priced stock options issued in connection with his promotion to Chief Technology Officer with an exercise price equal to the closing price of Equifax stock ($257.85) on the February 20, 2024 grant date.

6 | Represents full grant date fair value of stock and option awards granted to each NEO in 2024 computed in accordance with FASB ASC Topic 718, excluding the estimated effect of forfeitures. The premium-priced stock options granted in 2024 to our CEO cliff vest on February 9, 2027, subject to continued employment, and have a seven-year term. The market-priced stock options granted in 2024 to NEOs other than the CEO vest, subject to continued employment, one-third annually for three years following the grant date and have a ten-year term.

Additional Discussion of Material Items in Summary Compensation and Grants of Plan-Based Awards Tables

Our executive compensation policies and practices, pursuant to which the compensation set forth in the Summary Compensation Table and the Grants of Plan-Based Awards Table was paid or awarded, are described under “Compensation Discussion and Analysis” beginning on page 54. A summary of certain material terms of our compensation plans and arrangements is set forth below.

2024 Annual Incentive Plan

Annual incentive opportunities awarded to our NEOs are earned based on Company performance against one-year operating objectives and individual performance metrics. The actual amount of annual incentive earned by each NEO pursuant to the individual performance portion is reported in the “Non-Equity Incentive Plan Compensation” column in the Summary Compensation Table. Annual incentive plan thresholds, targets and maximums are identified for each NEO in the “Estimated Possible Payouts Under Non-Equity Incentive Plan Awards” column of the “2024 Grants of Plan-Based Awards” table on page 86. Additional information regarding the design of the annual incentive plan is included in the CD&A.

401(k) Plan

We sponsor a tax-qualified 401(k) Plan in which eligible salaried employees may participate in either a basic plan or an enhanced plan put into place following the 2008 freeze of certain benefits payable to non-grandfathered employees under the USRIP. For 2024, we matched either 50% of the first 6% of eligible pay, or 100% of the first 5% of eligible pay an employee contributed on a pre-tax or Roth after-tax basis to the plan (subject to the government limit on compensation, or $345,000 in 2024).

The following table shows the present value at December 31, 2024 of accumulated benefits payable to each of our NEOs at the earliest unreduced retirement age (age 60 or current age for executives over the age of 60), including the number of years of service credited to each NEO, under the USRIP and the SERP. Age 60 is the earliest age at which a participant can begin receiving an unreduced early retirement benefit under the SERP. No pre-retirement mortality was assumed. Mr. Gamble is currently eligible for retirement under the SERP. Mr. Ploder retired on September 30, 2024 and is currently eligible to start payments under the USRIP and SERP.

U.S. Retirement Income Plan

The USRIP is a tax-qualified defined benefit plan that covers eligible salaried U.S. employees. The USRIP is fully frozen for all U.S. employees, including for Mr. Ploder who is the only NEO who is a participant in the USRIP. For Mr. Ploder, service credit was frozen as of December 31, 2008, and salary increase was frozen as of December 31, 2012. Other grandfathered participants who were still employed on December 31, 2014 had their pension benefits fully frozen on such date.

Supplemental Retirement Plan

The SERP covers certain NEOs (Messrs. Gamble and Ploder) as designated by the Compensation Committee. Messrs. Begor, Borton, Horvath and Farshchi do not participate in the SERP. The plan provides benefits that supplement the USRIP benefits. The SERP provides an annual benefit equal to 2.5% of “average annual compensation” times years of service as a senior executive officer (up to 10 years), plus 1.67% of average annual earnings multiplied by years of service as a senior executive officer in excess of 10 years (up to 20 years). “Average annual compensation” for this purpose is generally determined by taking the monthly average of the participant’s compensation (including base salary and annual incentives) over the 36 consecutive month period during the participant’s employment with the Company in which he or she was paid the greatest amount of compensation, and multiplying such monthly average by 12. For service as a senior executive officer in excess of 20 years or in a position other than as a senior executive officer, a participant receives a “restoration benefit” using a formula similar to that of the USRIP, without the IRS limits on compensation. In general, only actual years of service with the Company are credited for purposes of determining the SERP benefit. The SERP was closed to new participants after January 1, 2016.

The benefit under the SERP is reduced by the benefit payable under the USRIP and is paid without regard to the limitations under Code Sections 401(a) and 415. However, the maximum aggregate benefit from both the SERP and the USRIP cannot exceed 50% of the executive’s average total earnings.

The normal retirement age under the SERP is age 65. However, participants can retire early once they reach age 55 if they have five years of service under the plan. The benefit would be reduced to reflect the early commencement of the benefit.

The benefit for senior executive officer service is unreduced at age 60, with reductions from age 60 for those who retire prior to age 60. The “restoration benefit” is reduced from normal retirement age to the participant’s early retirement age in the same manner as the USRIP. The normal form of benefit and optional forms of benefit are the same as those in the USRIP.

Non-Qualified Deferred Compensation

The following table sets forth information regarding the NEOs’ participation in our non-qualified deferred compensation plans in 2024. All of the balances relate to executives’ own deferred amounts. Cash deferrals are invested in investment funds available to the general public. Stock deferrals are deferred as stock equivalent units with earnings and losses solely attributable to changes in our stock price. We do not make any additional contributions to such plans, except as explained below with respect to the Supplemental Contribution Program.

During the past four years (2021-2024), our CEO made proactive, irrevocable elections under our deferred compensation program to defer 100% of his long-term incentives granted in the form of RSUs and performance shares. As a result of his voluntary, irrevocable deferral elections, our CEO will continue to be invested in Equifax for more than ten years following his tenure at the company. See page “CEO Equity Deferrals” on page 75 for more information.

1 | These amounts include salary, annual incentive plan and stock contributions made by NEOs and deferred into the Equifax Inc. Employee Deferred Compensation Plan (2022) and the Director and Executive Stock Deferral Plan. Accordingly, cash deferral amounts are included in the amounts reported in the “Salary” and the “Non-Equity Incentive Plan Compensation” columns in the Summary Compensation Table on page 83. Amounts in this table do not include equity subject to a deferral election but not yet vested. See page 75 for more information regarding our CEO’s irrevocable elections to defer $61 million of equity over a 10-year period following his retirement from Equifax.

2 | These amounts represent the Company’s contribution on behalf of the NEO under the Supplemental Contribution Program funded in February 2025 based on base salary and incentives earned in 2024. Participants in the SERP are not eligible to participate in the Supplemental Contribution Program.

3 | Aggregate earnings in the last fiscal year are not reported in the Summary Compensation Table because earnings were neither preferential nor above-market. These amounts include earnings (losses), dividends and interest provided on current contributions and existing balances, including the change in value of the underlying investment options in which the NEO is deemed to be invested.

4 | These amounts represent each NEO’s aggregate balance in the Equifax Inc. Employee Deferred Compensation Plan (2022) (including amounts earned under the 2024 AIP that were deferred in February 2025) and the Director and Executive Stock Deferral Plan and/or the Supplemental Contribution Program (including the Supplemental Contribution Program contributions made in February 2025 relating to 2024 eligible compensation) as of December 31, 2024. Amounts in this table do not include equity subject to a deferral election but not yet vested.

Supplemental Contribution Program

After the SERP was closed to new participants on January 1, 2016, the Company amended the Equifax 2005 Executive Deferred Compensation Plan to add provisions to permit senior executive officers designated by the Compensation Committee to receive supplemental retirement contributions (the “Supplemental Contribution Program”). NEOs and senior executive officers who participate in the SERP are not eligible to participate in the Supplemental Contribution Program. Messrs. Begor, Borton, Horvath and Farshchi participate in the Supplemental Contribution Program.

The Supplemental Contribution Program provides for an annual contribution equal to 10% of the sum of the eligible executive’s base salary and annual cash incentive earned for the year. The Company’s contributions are credited to an account for the executive and the executive directs the investments of the account among designated investment alternatives. The account fully vests upon the executive’s completion of three years of service after the date the executive becomes a participant in the plan. The account also fully vests upon the executive’s termination of employment as a result of death or disability.

Table of Contents

For Supplemental Contribution Program contributions credited for years prior to 2022, and upon the executive’s termination of employment after age 55 (or in the event of death or disability), the vested amount credited to the account is payable in a lump sum or in annual installments over a period of up to 15 years. If the executive terminates employment prior to age 55 (except for death or disability), the vested account is not payable until the executive attains age 55 and is paid in a lump sum.

For Supplemental Contribution Program contributions credited for 2022 and beyond, and upon the executive’s termination of employment at any age, the vested amount credited to these accounts are payable in a lump sum or in annual installments over a period of up to 10 years, beginning in the seventh month following termination of employment.

Deferred Compensation Plans

We maintain two frozen deferred compensation plans that, prior to their freezing, allowed for certain management employees to defer the receipt of compensation (such as salary, incentive compensation and/or stock from vested shares) until a later date based on the terms of the plans. These plans, the Director and Executive Stock Deferral Plan and the Equifax 2005 Executive Deferred Compensation Plan, were frozen, effective as of December 31, 2021, as described below. The Board adopted a new deferred compensation plan in 2021, the Equifax Inc. Employee Deferred Compensation Plan, which allows for certain management employees to defer the receipt of compensation earned for services performed in calendar years commencing on or after January 1, 2022, as described below. The benefits under our deferred compensation plans are represented by the assets of a grantor trust which, through our funding, makes investments in certain mutual funds. The purpose of this trust is to ensure the distribution of benefits to participants in the deferred compensation plans. However, all benefits under the plan are non-funded obligations of the Company and are subject to the claims of creditors in the event of bankruptcy.

Director and Executive Stock Deferral Plan (frozen December 31, 2021)

This nonqualified plan was frozen by the Board, effective as of December 31, 2021, and no deferral elections may be made under the plan in respect of compensation earned for services performed after such date. Prior to the freezing of the plan, it permitted the directors, NEOs and other senior leadership team members to defer receipt of compensation and taxes upon the vesting of RSUs and performance shares. Participants could defer 25%, 50%, 75% or 100% of the portion of the grant that is vesting. Stock deferrals track the performance of our common stock, with credit for dividends beginning with grants made in 2020. The participant receives the right to a number of shares of deferred stock. In general, amounts deferred under the plan are not paid until the participant retires. However, participants may also establish sub-accounts from which amounts are to be paid on specific pre-retirement timetables established by the director or executive officer, referred to as a scheduled withdrawal. Amounts deferred are paid in our common stock, either in a lump sum or in annual installments over a period of two years up to five years for retirement distributions, or up to five years for a scheduled withdrawal.

Equifax 2005 Executive Deferred Compensation Plan (frozen December 31, 2021)

This nonqualified plan was frozen by the Board, effective as of December 31, 2021, and no deferral elections may be made under the plan in respect of compensation earned for services performed after such date. This plan is a tax deferred compensation program for a limited number of executives, including NEOs, and provides a tax-favorable vehicle for deferring annual compensation, including base salary and annual or periodic incentives. Prior to the freezing of the plan, an executive could defer up to 75% of his or her base salary and up to 100% of any incentive payment. Amounts deferred are credited with gains or losses which mirror the performance of benchmark investment funds selected by the participant from among several publicly-available investment funds. The plan does not offer any above-market or preferential rates of return to the NEOs. Amounts deferred are paid, at the participant’s option, either in a lump sum or in annual installments over a period of up to 15 years for retirement or termination distributions, or up to five years for a scheduled withdrawal.

Equifax Inc. Employee Deferred Compensation Plan (2022)

The Equifax Inc. Employee Deferred Compensation Plan was adopted by the Board, effective as of November 4, 2021. This nonqualified plan allows for certain management or highly compensated employees, including NEOs, to defer the receipt of compensation earned for services performed in calendar years commencing on or after January 1, 2022. The plan is a tax deferred compensation program and provides a tax favorable vehicle for deferring annual compensation, including base salary and annual or periodic incentives, and long-term incentive compensation, including RSUs and

performance shares. Under the plan, a participant may defer up to 75% of his or her base salary and up to 100% of any cash or stock-based incentive compensation, including RSUs and performance shares. Any cash-based compensation that is deferred under the plan is credited with gains or losses which mirror the performance of benchmark investment funds selected by the participant from among several publicly-available investment funds. The plan does not offer any above-market or preferential rates of return to the NEOs. Any RSUs or performance shares that are deferred under the plan are credited in shares of deferred stock, which are notional shares equal in value to one share of our common stock. If any cash dividends or other distributions are paid with respect to our common stock between the date the deferred stock is credited to the participant’s account under the plan and the date the deferred stock is delivered to the participant, dividend equivalent units will be credited in respect of the participant’s deferred stock and will be deemed reinvested in additional deferred stock. Deferred stock credited to the plan is paid in shares of our common stock.

Amounts deferred under the Equifax Inc. Employee Deferred Compensation Plan are paid, at the participant’s option, either in a lump sum or in annual installments over a period of up to 10 years for distributions upon a termination of employment, or up to five years for a scheduled withdrawal. The Supplemental Contribution Program is continued under the Equifax Inc. Employee Deferred Compensation Plan on substantially the same terms as set forth in the frozen Equifax 2005 Executive Deferred Compensation Plan, except that payment of a participant’s vested supplemental contribution amounts will be made following his or her termination of employment either in a lump sum or in annual installments over a period of up to 10 years, as elected by the participant. Participants in the Equifax Inc. Employee Deferred Compensation Plan will be charged a proportionate share of the administrative fees incurred in connection with its administration.

Potential Payments Upon Termination or Change In Control

The following tables summarize the value of potential payments and benefits that our NEOs would receive if they had terminated employment on December 31, 2024 under the circumstances shown. The tables exclude amounts that would be paid in the normal course of continued employment, such as accrued but unpaid salary and earned annual cash incentive for 2024, and vested account balances in our 401(k) Plan that are generally available to all of our active U.S. salaried employees. Actual amounts to be paid can only be determined at the time of such executive’s termination of service.

Ploder Retirement

Mr. Ploder stepped down from his role as Executive Vice President, President, Workforce Solutions, on May 6, 2024 and retired from Equifax on September 30, 2024. Mr. Ploder and the Company entered into a transition agreement and general release related to his retirement whereby, in recognition of his service, the Company agreed to amend the terms of certain equity awards excluded from retirement vesting eligibility such that the awards will continue to vest in accordance with the original vesting schedule after Ploder’s termination date ($1.76 million value as of September 30, 2024).

Payments Made Upon Termination

Regardless of the manner in which an NEO’s employment terminates, the executive is entitled to receive amounts earned during the executive’s term of employment. The amounts include:

| ● | annual incentive compensation earned during the fiscal year for termination due to retirement, job elimination, death or disability;

| ● | vested shares awarded under the Omnibus Incentive Plan;

| ● | amounts contributed under the 401(k) Plan for termination due to retirement, job elimination, death or disability;

| ● | amounts contributed under executive compensation deferral programs for termination due to death or disability; and

| ● | accrued but unused vacation pay and amounts accrued and vested under the USRIP and the SERP.

Equifax Inc. Severance Plan

Under this plan, our full-time U.S. salaried employees are eligible for a severance benefit in the event: (i) their employment is terminated because of the elimination of their position, unless they were offered replacement employment as defined in the plan; (ii) their office is relocated to a place requiring a commute more than 35 miles longer than their prior commute; or (iii) they are terminated due to inability or failure to meet job expectations, provided the employee signs a general release of claims. The amount of the severance benefit is determined based on the employee’s length of service and base salary. In general, for job elimination or relocation, an eligible exempt employee is entitled to receive four weeks of severance for any portion of their first year of service plus two weeks for each year of completed service, up to 52 weeks. Termination for inability or failure to meet job expectations of eligible exempt employees entitles the employee to four weeks of severance for less than five years of service, eight weeks of severance for at least five but less than 10 years of service, and 12 weeks of severance for 10 or more years of service.

intact leadership team to the successor organization and focus the team on shareholder objectives rather than how the outcome may affect them personally. The CIC Plan is not intended to replace or affect other compensation elements.

The CIC Plan provides the participating NEOs with severance benefits in the event that (i) a “change in control” of the Company occurs, and (ii) within 6 months prior to or within 24 months after the change in control, a participating NEO is terminated by the Company without “cause” or by the NEO for “good reason” (referred to as a “CIC Qualifying Termination”). If a CIC Qualifying Termination occurs, the NEO is eligible to receive:

| ● | a cash payment equal to two times the NEO’s current base salary and target annual incentive for the year of termination;

| ● | a pro rata target annual incentive for the year of termination;

| ● | a cash payment equal to 24 months of the cost of COBRA coverage for the NEO and his or her dependents; and

| ● | full vesting of any unvested supplemental retirement benefits.

Severance payments to an NEO are generally capped such that the payments will be reduced to satisfy the “parachute payment” limits of Code Section 280G.

Pursuant to the CIC Plan, a “change in control” is deemed to occur upon:

| ● | an accumulation by any person, entity or group of 20% or more of the Company’s common stock;

| ● | a business combination resulting in shareholders immediately prior to the combination owning less than two-thirds of the Company’s common stock;

| ● | the members of the current Board of Directors ceasing to constitute a majority of the Board of Directors, except for new directors that are regularly elected; or

| ● | shareholder approval of a plan of complete liquidation or dissolution of the Company or an agreement for the sale of disposition of all or substantially all of the Company’s assets.

Under the terms of the CIC Plan, the participating NEOs become subject to standard definitions of “Cause” and “Good Reason” that align with contemporary best practices and severance benefits become subject to the Company’s compensation clawback policy. An NEO can be terminated for “cause” as a result of: (i) conviction or plea of guilty or nolo contendere to a felony or other serious crime involving moral turpitude; (ii) willful misconduct that is materially injurious to the Company or any of its subsidiaries (whether financially, reputationally, or otherwise); (iii) willful and continued failure of an NEO to perform his or her duties and responsibilities (other than as a result of physical or mental illness or injury) after receipt of written notice of such failure, provided that the NEO shall have 30 days after the date of receipt of such notice in which to cure such failure (to the extent cure is possible); (iv) gross negligence in managing the material risks of the Company or its subsidiaries; (v) material breach of the CIC Plan or of the restrictive covenants after receipt of written notice of such breach, provided, that the NEO shall have 30 days after the date of receipt of such notice in which to cure such breach (to the extent cure is possible); or (vi) material violations of law or the Company’s Code of Conduct or insider trading policy, any of which results in material financial or reputational harm to the Company. An NEO can terminate his or her employment for “good reason” based upon (i) a material adverse change in the NEO’s duties, authority, or responsibilities; (ii) a material reduction in the NEO’s base salary (which for purposes of the CIC Plan shall mean a reduction of 10% or more) or the target percentage of base salary under the Annual Incentive Plan; (iii) a material reduction in the value of the NEO’s annual equity or long term incentive award opportunity; (iv) a relocation of the NEO’s primary work location of more than 35 miles; or (v) the material breach by the Company of the terms of the CIC Plan.

In order to be eligible to receive severance benefits, the NEO must execute a release of claims against the Company and comply with confidentiality, non-competition and non-solicitation restrictive covenants. In addition, severance benefits are subject to the Company’s clawback policy.

Change in Control and Termination Provisions of Other Plans

Annual Incentive Plan

Under the AIP, which is established under the 2023 Omnibus Incentive Plan, an NEO would forfeit his or her award if he or she voluntarily terminated his or her employment other than for “good reason” (as defined in the plan) prior to year-end or if he or she is terminated by us for “cause” (as defined in the plan). However, the executive would receive a pro rata award under the plan if the executive’s employment is terminated prior to year-end as a result of death, disability, retirement or job elimination. If there is a change in control event and an NEO is terminated without cause or

terminates for “good reason,” payments for annual incentive opportunities would be made to the executive in the manner described under “Payments Made Upon a Change in Control” on page 101.

Omnibus Incentive Plans

Although subject to the discretion of the Compensation Committee, under the 2008 Omnibus Incentive Plan, 2023 Omnibus Incentive Plan and applicable award agreements, equity awards to our NEOs include a “double-trigger” change in control provision to limit accelerated vesting in the event of a change in control of Equifax to those situations where an executive is terminated without cause, the executive terminates for good reason or the acquirer fails to assume the awards.

Rabbi Trust

We maintain a trust agreement with an independent trustee establishing a springing rabbi trust for the purpose of funding benefits payable to participants (including participating NEOs) under our SERP. The trust is a grantor trust, irrevocable except in the event of an unfavorable ruling by the IRS as to the tax status of the trust or certain changes in tax law. It is currently funded with a nominal amount of cash. Future contributions will be made to the grantor trust if and when required by the provisions of the trust or at the discretion of the Company. If there is a change in control, the grantor trust must be fully funded, within 10 days following the change in control, with an amount equal to the entire benefit to which each participant would be entitled under the covered plan as of the date of the change in control (calculated on the basis of the present value of the projected future benefits payable under the covered plan). “Change in Control” is defined in substantially the same manner as in the CIC Plan described under “Payments Made Upon a Change in Control,” except that (i) there is no “double trigger,” (ii) a business combination resulting in shareholders immediately prior to the combination owning equal to or less than two-thirds of the Company’s common stock constitutes a change in control, (iii) a business combination in which there is not a change in at least a majority of the members of the Board of Directors does not constitute a change in control and (iv) a change in a majority of the members of the Board of Directors does not constitute a change in control. The assets of the grantor trust are required to be held separate and apart from the other funds of Equifax and its subsidiaries, but remain subject to the claims of general creditors under applicable state and federal law.

Director Fees

Director cash compensation in 2024 consisted of an annual cash retainer of $90,000 and an annual cash retainer of $30,000 for the Audit Committee Chair, $25,000 for the Compensation Committee Chair, $20,000 for the Governance Committee Chair and $30,000 for the Technology Committee Chair. An annual cash retainer is also paid, in the amount of $15,000 for Audit Committee members, $12,500 for Compensation Committee members, $10,000 for Governance Committee members and $15,000 for Technology Committee members. An annual cash retainer of $150,000 was paid to Mr. Feidler as Independent Chairman. Effective January 1, 2025, the annual cash retainer increased to $100,000.

By paying directors an annual retainer, the Company compensates each non-management director for his or her role and judgment as an advisor to the Company, rather than for his or her attendance or effort at individual meetings. Directors with added responsibility are recognized with higher cash compensation as noted above.

Equity Awards

Upon joining our Board, each independent director receives a one-time grant of RSUs with a grant date fair value of $200,000 under our shareholder-approved Omnibus Incentive Plan. In addition, each independent director receives an annual long-term incentive grant of RSUs with a grant date fair value of $200,000 on the date of the annual meeting of shareholders. The initial and annual grants vest three years and one year, respectively, after the grant date, with accelerated vesting in the event of the director’s death, disability, retirement or a change in control of the Company. These equity grants are designed to further align the interests of our directors with those of our shareholders and to attract and retain highly-qualified directors through equity ownership. RSUs granted to directors accrue dividend equivalent units. Effective January 1, 2025, the annual grant value increased to $220,000.

On May 2, 2024, Barbara Larson received a one-time grant of RSUs with a grant date fair value of $200,030 in connection with her election to the Board. On May 2, 2024, each independent director then serving received an annual long-term incentive grant of RSUs with a grant date fair value of $200,030.

Stock Ownership Requirement

Each independent director is required to own Equifax common stock with a market value of at least five times his or her annual cash retainer. New directors have five years to achieve the ownership requirement. Under our insider trading policy, our directors are prohibited from purchasing or selling financial instruments (including prepaid variable forward contracts, equity swaps, collars, exchange funds and other derivative securities), or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Equifax securities. We also prohibit our directors from holding our stock in a margin account or pledging our stock as collateral for a loan.

Equifax 2005 Director Deferred Compensation Plan (frozen December 31, 2021)

The Equifax 2005 Director Deferred Compensation Plan was frozen by the Board, effective as of December 31, 2021, and no deferral elections may be made under the plan in respect of compensation earned for services performed after such date. Prior to the freezing of the plan, each director could elect to defer receipt of up to 100% of his or her stock-based or cash retainer fees. A director who elected to defer his or her fees is credited with a number of share units having an equivalent value at the end of each quarter based on his or her advance deferral election, with credit for dividends beginning with grants made in 2020. Share units are equivalent to shares of the Company’s common stock, except that share units have no voting rights. In general, amounts deferred are not paid until the director retires from the Board. However, directors may also establish sub-accounts from which amounts are to be paid on specific pre-retirement timetables established by the director. At the end of the applicable deferral period, the director receives a share of common stock for each share unit awarded. Such shares are received either in a lump sum or over a period not to exceed 15 years for retirement distributions, or up to five years for a scheduled withdrawal, as elected in advance by each director.

Director and Executive Stock Deferral Plan (frozen December 31, 2021)

The Director and Executive Stock Deferral Plan was frozen by the Board, effective as of December 31, 2021, and no deferral elections may be made under the plan in respect of compensation earned for services performed after such date. Prior to the freezing of the plan, each director could elect to defer up to 100% of his or her annual and/or new director RSU grant, including dividend equivalent units, plus taxes otherwise due upon the vesting of RSUs. A director who elected to defer his or her annual and/or new director RSU grant is credited with a number of share units as of the vesting date based on his or her advance deferral election. In general, amounts deferred under the plan are not paid until the director retires from the Board. However, directors may also establish sub-accounts from which amounts are to be paid on specific pre-retirement timetables established by the director. Amounts deferred are paid in shares of our common stock, at the director’s option, either in a lump sum or in annual installments over a period of up to 15 years for retirement distributions, or up to five years for a scheduled withdrawal.

Equifax Inc. Board of Directors Deferred Compensation Plan (2022)

The Equifax Inc. Board of Directors Deferred Compensation Plan was adopted by the Board, effective as of November 4, 2021. This nonqualified plan allows for non-employee members of the Board to defer the receipt of compensation earned for services performed in calendar years commencing on or after January 1, 2022. The plan is a tax deferred compensation program and provides a tax favorable vehicle for deferring stock-based and cash retainer fees. Under the plan, a director may defer up to 100% of his or her stock-based and/or cash retainer fees. Any compensation that is deferred by a director is credited in shares of deferred stock, which are notional shares equal in value to one share of our common stock. If any cash dividends or other distributions are paid with respect to our common stock between the date the deferred stock is credited to the director’s account under the plan and the date the deferred stock is delivered to the director, dividend equivalent units will be credited in respect of the director’s deferred stock and will be deemed reinvested in additional deferred stock. Deferred stock credited to the plan is paid in shares of our common stock.

Amounts deferred under the Equifax Inc. Board of Directors Deferred Compensation Plan are paid, at the director’s option, either in a lump sum or in annual installments over a period of up to 10 years for distributions upon a termination of services as a member of the Board, or up to five years for a scheduled withdrawal. Participants in the Equifax Inc. Board of Directors Deferred Compensation Plan will be charged a proportionate share of the administrative fees incurred in connection with its administration.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s directors, executive officers, and persons who own more than ten percent of a registered class of the Company’s equity securities to file reports of securities ownership and changes in such ownership with the SEC. Directors, executive officers and greater than ten percent shareholders also are required by SEC rules to furnish the Company with copies of all Section 16(a) forms they file. Based upon a review of copies of such forms furnished to the Company and written representations provided by the reporting persons, the Company believes that all Section 16(a) filing requirements were timely met in 2024, except for one Form 4 reporting a transaction for Todd Horvath that was filed late due to an administrative error.

Audit Committee Report

The Audit Committee consists of the five directors named below. The Audit Committee operates pursuant to a written charter adopted by the Board of Directors, which is reviewed annually by the Audit Committee. The Board has determined that each member of the Audit Committee is independent and qualified to serve in accordance with the NYSE listing standards, applicable SEC rules and the Audit Committee charter.

The Audit Committee assists the Board in its oversight of: (i) the integrity of the Company’s financial statements and other financial information provided to its shareholders; (ii) the Company’s compliance with legal and regulatory requirements; (iii) the qualifications, independence and performance of the Company’s independent auditor; (iv) the performance of the Company’s internal audit function; (v) and the integrity of the Company’s internal control over financial reporting and its financial reporting processes. The Audit Committee also oversees risk management with respect to cybersecurity in coordination with the Technology Committee.

Management of the Company is responsible for the preparation and presentation of the Company’s financial statements, the effectiveness of internal control over financial reporting, and maintaining procedures that are reasonably designed to assure compliance with accounting standards and applicable laws and regulations. The Company’s independent registered public accounting firm, Ernst & Young LLP, is responsible for performing an independent audit of the consolidated financial statements and of the Company’s internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States) (the “PCAOB”). The Audit Committee’s responsibility is to monitor and oversee these processes on behalf of the Board of Directors.

In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed with management and Ernst & Young the audited financial statements for the fiscal year ended December 31, 2024. The Audit Committee has reviewed and discussed with management and Ernst & Young the quarterly financial statements for each quarter in such fiscal year, management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2024, Ernst & Young’s evaluation of the Company’s internal control over financial reporting as of that date, and audit plans and results. The Audit Committee has also discussed with Ernst & Young the matters required to be discussed with the independent auditor by the applicable requirements of the PCAOB.

The Audit Committee has received from Ernst & Young the written disclosures required by applicable requirements of the PCAOB regarding Ernst & Young’s communications with the Audit Committee concerning independence, and has discussed with Ernst & Young its independence. The Audit Committee has also considered whether the provision of specific non-audit services by Ernst & Young is compatible with maintaining its independence and determined that the services provided by Ernst & Young for fiscal year 2024 were compatible with, and did not impair, its independence.

In reliance on the reviews and discussions referred to above, the Audit Committee has recommended to the Board of Directors that the financial statements referred to above be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Proposal 3

Ratification of Appointment of Ernst & Young LLP as Independent Registered Public Accounting Firm for 2025

The Audit Committee has selected Ernst & Young LLP (“Ernst & Young”) as the Company’s independent registered public accounting firm for fiscal year 2025, and the Board is asking shareholders to ratify that selection. Although current laws, rules, and regulations, as well as the charter of the Audit Committee, require the Audit Committee to engage, retain, and supervise the Company’s independent registered public accounting firm, the Board considers the selection of the independent registered public accounting firm to be an important matter of shareholder concern and is submitting the selection of Ernst & Young for ratification by shareholders as a matter of good corporate practice. Additionally, in conjunction with the mandated rotation of the Audit Firm’s lead engagement partner, the Audit Committee and its chair are directly involved in the selection of Ernst & Young’s new lead engagement partner. The members of the Audit Committee and the Board believe that the continued retention of Ernst & Young is in the best interests of the Company and its shareholders. If the shareholders do not ratify the selection of Ernst & Young, the Audit Committee will review the Company’s relationship with Ernst & Young and take such action as it deems appropriate, which may include continuing to retain Ernst & Young as the Company’s independent registered public accounting firm.

Ernst & Young has served as our independent registered public accounting firm since 2002. A representative of Ernst & Young will be available during the 2025 Annual Meeting to make a statement if such representative desires to do so and to respond to appropriate questions.

Independent Registered Public Accounting Firm Fees

The following table sets forth the fees of Ernst & Young for services rendered to the Company for the fiscal years ended December 31, 2024 and 2023:

​ | ​ | ​ | ​ | ​ | ​ | ​
Fee Category |  | 2024 |  | 2023
Audit Fees 1 | ​ | $ | 6,287,020 | ​ | $ | 7,103,720
Audit-Related Fees 2 | ​ |  | 0 | ​ |  | 331,250
Tax Fees 3 | ​ |  | 769,060 | ​ |  | 853,690
All Other Fees 4 | ​ |  | 19,700 | ​ |  | 8,890
TOTAL | ​ | $ | 7,075,780 | ​ | $ | 8,297,550

1 | Services normally provided by the Company’s independent registered public accounting firm consists of fees and expenses for professional services rendered for: (i) the integrated audit of our annual consolidated financial statements and internal control over financial reporting; (ii) review of the interim consolidated financial statements included in our quarterly reports to the SEC; (iii) statutory and regulatory filings or engagements; (iv) accounting consultations on matters addressed during the audit or interim reviews; and (v) SEC filings, including comfort letters, consents and comment letters.

2 | Consists of fees and expenses for services that reasonably are related to the performance of the audit, review of our consolidated financial statements or diligence-related efforts and are not reported under “Audit Fees.”

3 | Consists of fees and expenses for professional services related to tax planning and tax advice.

4 | Consists of fees for products and services provided by Ernst & Young which are not included in the first three categories above.

Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services Performed by the Independent Registered Public Accounting Firm

The Company maintains a pre-approval policy that mandates that the Audit Committee approve the audit and non-audit services in advance. All audit and non-audit services for the fiscal year ended December 31, 2024 were either pre-approved by the Audit Committee or were approved pursuant to the Audit Committee’s pre-approval policy. The Audit Committee has authorized its Chair to pre-approve certain permissible audit and non-audit services that arise between Audit Committee meetings, provided the Audit Committee is informed of the decision to pre-approve the services at its next scheduled meeting. In its pre-approval of non-audit services and fees, the Audit Committee considers, among other factors, the possible effect of the performance of such services on the auditor’s independence. The Audit Committee has determined that performance of services other than audit services is compatible with maintaining the independence of the Company’s independent registered public accounting firm. See “Audit Committee Report” on page 117.

To avoid potential conflicts of interest in maintaining auditor independence, the law prohibits a publicly traded company from obtaining certain non-audit services from its independent registered public accounting firm. In 2023 and 2024, we did not obtain any of these prohibited services from Ernst & Young. The Company uses other accounting firms for these types of non-audit services.

Proposal 4

Approval of Amendments to our Articles of Incorporation to Eliminate the Supermajority Voting Requirements

Our Board regularly considers a broad range of corporate governance topics and is committed to adopting governance practices that are beneficial to the Company and our shareholders. After careful consideration of shareholder feedback, current market practice and the recommendation of the Governance Committee, the Board has unanimously determined that it would be in the best interests of Equifax and our shareholders to amend the Company’s Amended and Restated Articles of Incorporation (the “Articles of Incorporation”) to remove supermajority voting thresholds.

The Articles of Incorporation currently require the affirmative vote of not less than two-thirds (2/3) of the votes entitled to be cast in order to amend certain provision of the Articles of Incorporation. If shareholders approve these amendments to the Articles of Incorporation, the Company’s governing documents will provide that the voting standard for all matters, except for contested elections of directors or as required by applicable law or regulation, is a majority of the votes cast favoring the action. As required by the Georgia Business Corporation Code, this proposal requires the approval of a majority of the votes entitled to be cast on the proposal.

The Board is now asking the Company’s shareholders to approve the amendments to the Articles of Incorporation as described below.

Equifax’s Current Supermajority Standards

The Articles of Incorporation currently require the affirmative vote of the holders of not less than two-thirds (2/3) of the votes entitled to be cast to make, alter, amend, change, add to or repeal any provision of the Articles of Incorporation or the bylaws of the Company inconsistent with Article IV of the Articles of Incorporation, unless such action is recommended by a majority of the Board.

Article IV of the Articles of Incorporation relates to, among other things, the Company’s prior classified board structure which was declassified over ten years ago, the size of the Board, vacancies on the Board and the amendment, repeal and adoption of bylaws.

Proposed Amendments

The amendments to the Articles of Incorporation (the “Amendments”) remove the supermajority voting provision and inoperative language related to the Company’s prior classified board structure and declassification.

If shareholders approve the Amendments, the Company’s governing documents will provide that the voting standard for all matters, except for contested elections of directors or as required by applicable law or regulation, is a majority of the votes cast favoring the action.

Rationale for Proposed Amendments

In December 2024, the Board voted to approve the Amendments and to recommend that the Company’s shareholders approve the Amendments at the 2025 Annual Meeting.

The Board is committed to strong corporate governance practices and regularly assesses ways to improve the Company’s practices. In determining whether to propose the Amendments, the Board carefully considered various arguments in support of and against the Amendments. The Board recognizes that a supermajority threshold for certain governing document provisions, such as the amendment, repeal or adoption of bylaws may promote continuity and stability in the Company’s corporate governance practices. While the Board continues to believe that these are important benefits, the Board has also considered that supermajority requirements may have the effect of reducing the accountability of directors to shareholders, and recognizes the benefit of providing shareholders an opportunity to participate in corporate governance. The Board also recognizes that a growing number of public companies have proposed eliminating supermajority voting requirements and these proposals have generally received strong support

​

​ | ​
120 | 2025 Proxy Statement

​

Table of Contents

from shareholders. Further, the Board recognizes that the supermajority voting threshold in the Articles of Incorporation was more beneficial when the Company had a classified board structure, which is now no longer relevant.

In view of the considerations described above, the Board, upon the recommendation of the Governance Committee, has unanimously determined to eliminate the supermajority voting threshold as proposed.

Text and Effectiveness of the Proposed Amendments

The complete text of the amendments to Article IV of the Articles of Incorporation is set forth below with deletions indicated by strike-throughs and additions indicated by underlining:

ARTICLE IV

(a) Subject to the rights of the holders of any outstanding series of Preferred Stock or any other outstanding class or series of shares of the Corporation as may be specified in or authorized by these Amended and Restated Articles of Incorporation, the business and affairs of the Corporation shall be managed by, or under the direction of, a Board of Directors comprised as follows:

1. The Board of Directors of the Corporation shall consist of not less than nine nor more than 20 Directors, the exact number of Directors to be determined from time to time by a resolution of the Board of Directors.

2. Subject to the provisions of Section 3 of this Article IV, the Directors shall be divided into three classes, designated as Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of Directors constituting the entire Board of Directors. At each Annual Meeting of Shareholders, successors to the class of Directors whose term expires at that Annual Meeting of Shareholders shall be elected for a three-year term. If the number of Directors has changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of Directors in each class as nearly equal as possible, and any additional Director of any class elected to the Board of Directors to fill a vacancy resulting from an increase in such a class shall hold office for a term that shall coincide with the remaining term of that class, unless otherwise required by law, but in no case shall a decrease in the number of Directors for a class shorten the term of an incumbent Director. A Director shall hold office until the Annual Meeting of Shareholders for the year in which such Director’s term expires and until his or her successor shall be elected and qualified, subject, however, to prior death, resignation, retirement, disqualification or removal from office.

3. Notwithstanding anything contained in Section 2 of this Article IV to the contrary, beginning at the 2010 Annual Meeting of Shareholders, Directors shall be elected annually for terms of one year, except that any Director whose term expires at the 2011 Annual Meeting of Shareholders or the 2012 Annual Meeting of Shareholders shall continue to hold office until the end of the term for which such Director was elected or appointed and until such Director’s successor shall have been elected and qualified, subject, however, to prior death, resignation, retirement, disqualification or removal from office. Accordingly, (i) at the 2010 Annual Meeting of Shareholders, the Directors whose terms expire at that meeting shall be elected to hold office for a one-year term expiring at the 2011 Annual Meeting of Shareholders; (ii) at the 2011 Annual Meeting of Shareholders, the Directors whose terms expire at that meeting shall be elected to hold office for a one-year term expiring at the 2012 Annual Meeting of Shareholders; and (iii) at the 2012 Annual Meeting of Shareholders, the Directors whose terms expire at that meeting shall be elected to hold office for a one-year term expiring at the 2013 Annual Meeting of Shareholders. Directors shall be elected annually for terms expiring at the next Annual Meeting of Shareholders.

4. Except as otherwise required by law, any vacancy on the Board of Directors resulting from death, resignation, retirement, disqualification, removal from office or any other reason and any newly created directorships resulting from an increase in the authorized number of Directors or any other reason may be filled by a majority of the Directors then in office, even if less than a quorum, or by a sole remaining Director. Any Director so chosen shall hold office until the next Annual Meeting of the Shareholders and until his or her successor has been duly elected and qualified. No decrease in the number of authorized Directors shall shorten the term of any incumbent Director.

(b) Except as may be prohibited by law or by these Amended and Restated Articles of Incorporation, the Board of Directors shall have the right to make, alter, amend, change, add to, or repeal the By-laws of the Corporation, and have the right (which, to the extent exercised, shall be exclusive) to establish the rights, powers, duties, rules and procedures that from time to time shall govern the Board of Directors, each of its members, including without limitation, the vote required for any action by the Board of Directors, and that from time to time shall affect the Directors’ powers to

​

​ | ​

​

Table of Contents

manage the business and affairs of the Corporation. No By-law shall be adopted by shareholders that shall impair or impede the implementation of the foregoing.

(c) Notwithstanding any other provisions of these Amended and Restated Articles of Incorporation or the By-laws of the Corporation (and notwithstanding the fact that a lesser percentage for separate class vote for certain actions may be permitted by law, by these Amended and Restated Articles of Incorporation or by the By-laws of the Corporation), the affirmative vote of the holders of not less than two-thirds (2/3) of the votes entitled to be cast by the holders of all then outstanding shares of Voting Stock, voting together as a single class, shall be required to make, alter, amend, change, add to or repeal any provision of these Amended and Restated Articles of Incorporation or the By-laws of the Corporation inconsistent with this Article IV; provided, however, that this Article IV(c) shall not apply to, and such two-thirds (2/3) vote shall not be required to alter, amend, change, add to or repeal any provisions of the By-laws relating to this Article IV, or this Article IV of these Amended and Restated Articles of Incorporation, recommended by a majority of the Board of Directors.

(d) The invalidity or unenforceability of this Article IV, or any portion hereof, or of any action taken pursuant to this Article IV shall not affect the validity or enforceability of any other provision of these Amended and Restated Articles of Incorporation, any action taken pursuant to such other provision, or any action taken pursuant to this Article IV.

VOTE REQUIRED

The affirmative vote of shareholders holding a majority of the votes entitled to be cast on the proposal is required to approve the proposed amendments.

Proposal 5

Shareholder Proposal Regarding
Simple Majority Vote

John Chevedden, 2215 Nelson Avenue — No. 205, Redondo Beach, CA 90278, owner of at least $2,000 worth of shares of the Company’s common stock, has notified the Company that it intends to present a proposal for consideration at the Annual Meeting. As required by the Exchange Act, the text of the shareholder proposal and supporting statement appear as submitted to the Company by the proponent. The Board and the Company accept no responsibility for the contents of the proposal or the supporting statement.

Proposal 5 – Simple Majority Vote

Shareholders request that our board take each step necessary so that each voting requirement in our charter and bylaws (that is explicit or implicit due to default to state law) that calls for a greater than simple majority vote be replaced by a requirement for a majority of the votes cast for and against applicable proposals, or a simple majority in compliance with applicable laws. If necessary this means the closest standard to a majority of the votes cast for and against such proposals consistent with applicable laws. This includes making the necessary changes in plain English.

Shareholders are willing to pay a premium for shares of companies that have excellent corporate governance. The supermajority voting requirements of Equifax have been found to be one of 6 entrenching mechanisms that are negatively related to company performance according to "What Matters in Corporate Governance" by Lucien Bebchuk, Alma Cohen and Allen Ferrell of the Harvard Law School. Supermajority requirements are used to block initiatives supported by most shareowners but opposed by a status quo management.

This proposal topic won from 74% to 88% support at Weyerhaeuser, Alcoa, Waste Management, Goldman Sachs, FirstEnergy and Macy’s. These votes would have been higher than 74% to 88% if more shareholders had access to independent proxy voting advice.

This proposal topic, as a shareholder proposal, received 98%-support at the 2023 annual meetings of American Airlines and The Carlyle Group. This proposal topic also received 98% support each at Domino’s Pizza, FMC Corporation, ConocoPhillips, Masco Corporation and Power Integrations in 2024.

The overwhelming shareholder support for this proposal topic at hundreds of major companies raises the question of why Equifax has not initiated this proposal topic on its own. It also raises the question that Equifax may be overlooking other areas of corporate governess improvement that could easily be adopted to increase shareholder value at virtually no cost.

Support Simple Majority Vote — Proposal 5

BOARD’S STATEMENT OPPOSING PROPOSAL 5

The Board of Directors has carefully considered this proposal and believes it is not in the best interests of the Company or its shareholders. The Board recommends a vote “AGAINST” Proposal 5 for the following reasons:

The Board has carefully considered this proposal and concluded that its adoption is unnecessary in light of the amendment to our Amended and Restated Articles of Incorporation that we are asking our shareholders to approve in Proposal 4. The Company's own proposal in Proposal 4, which is unanimously supported by the Board in light of current market practice and the recommendation of the Governance Committee, will have the effect of eliminating the only supermajority voting requirement explicitly referenced in any of our governing documents, making this proposal unnecessary.

Table of Contents

As described in the Company's proposal in Proposal 4, the Board cannot unilaterally remove the supermajority voting requirement from our Amended and Restated Articles of Incorporation as Georgia law requires shareholder approval. For this reason, the Board has approved and recommended that shareholders approve the amendment to our Amended and Restated Articles of Incorporation to eliminate the supermajority voting requirement described in Proposal 4. If we receive shareholder approval of the Company's proposal in Proposal 4, the amendment will be filed promptly with the Secretary of State of the State of Georgia and there will be no remaining supermajority voting standards in our governing documents.

We believe that the Company’s proposal in Proposal 4 sufficiently addresses this topic.

Board Recommen dation The Board recommends a vote “AGAINST” Proposal 5.

What is the difference between holding shares as a registered shareholder and as a beneficial owner?

If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, you are considered the “registered stockholder” of those shares. We mail the proxy materials and our Annual Report to you directly.

If your shares are held in street name with a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of the shares that are registered in street name. In this case, the proxy materials and our Annual Report will be 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 on how to vote your shares by following the voting instructions included in the materials.

Employees with shares allocated in an employee benefit plan account will vote shares allocated to their benefit plan account electronically and will not receive a paper mailing for those shares. Such employees should review the information on procedures for voting by employees on page 128.

What is the procedure for voting?

Shareholders of record

Shareholders of record may attend and cast their votes by attending the 2025 Annual Meeting in person or virtually, as described on page 125.

In addition, shareholders of record may cast their vote by proxy and participants in the Company’s benefit plans may submit their voting instructions by:

| ● | Using the internet at the web address noted in the proxy materials email or proxy card you received (if you have access to the internet, we encourage you to vote in this manner);

| ● | Using the toll-free telephone number listed on the proxy card (if you received one); or

| ● | Signing, completing and returning a proxy card (if you received one) in the provided postage-paid envelope.

Votes cast through internet and telephone voting procedures are authenticated by use of a personal identification number. This procedure allows shareholders to appoint a proxy (or Company benefit plan participants to provide voting instructions) and to confirm that their actions have been properly recorded. Specific instructions to be followed are set forth on the proxy materials email or proxy card (if you received one).

Beneficial owners

If you are the beneficial owner of shares held in “street name,” you have the right to direct your bank, broker or other nominee on how to vote your shares by using the voting instruction form provided to you by them, or by following their instructions for voting through the Internet or by telephone. In the alternative, you may attend and cast your vote during the meeting as described on page 125. If you are a beneficial owner but do not have a control number, you may gain access to the meeting by contacting your broker or by following the instructions included with your proxy materials. In order for your shares to be voted on all matters presented at the meeting, we urge all shareholders whose shares are held in street name by a bank, brokerage firm or other nominee to provide voting instructions to your bank, brokerage firm or other nominee.

Can I change my proxy vote?

Yes. If you are a registered shareholder, you can change your proxy vote or revoke your proxy at any time before the 2025 Annual Meeting by:

| ● | Authorizing a new vote electronically through the Internet or by telephone up until 11:59 p.m., Eastern Time, on May 7, 2025;

| ● | Delivering a written revocation of your proxy to Equifax Inc., Attn: Office of Corporate Secretary, P.O. Box 4081, Atlanta, Georgia 30302, before your original proxy is voted at the Annual Meeting;

| ● | Returning a signed proxy card with a later date; or

| ● | Voting during the Annual Meeting.

If you are a beneficial owner of shares, you can submit new voting instructions by contacting your broker, bank or other nominee. You can also vote during the 2025 Annual Meeting as described above.

Your attendance at the 2025 Annual Meeting does not revoke your proxy. Unless you vote during the meeting, your last valid proxy prior to or at the 2025 Annual Meeting will be used to cast your vote.

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

Proxies that are signed and returned but do not contain voting instructions will be voted:

| ● | FOR the election of the ten director nominees listed in Proposal 1.

| ● | FOR the advisory vote to approve the compensation of our NEOs (Proposal 2).

| ● | FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the 2025 fiscal year (Proposal 3).

| ● | FOR the approval of amendments to our Articles of Incorporation to eliminate supermajority voting requirements (Proposal 4).

| ● | AGAINST the shareholder proposal regarding simple majority voting requirements (Proposal 5).

Table of Contents

In accordance with the Board’s recommendation by the individuals named as proxy holders in the proxy card, if any other matters are properly brought before the 2025 Annual Meeting.

How do I vote if I participate in one of the Company’s 401(k) or defined contribution plans?

Participants in the Equifax Inc. 401(k) Plan and the Equifax Canada Retirement Savings Program for Salaried Employees (collectively, the “Company Plans”) may instruct the applicable plan trustee how to vote all shares of Company common stock allocated to their accounts. To allow sufficient time for the plan trustees to vote, the trustees must receive your voting instructions no later than 11:59 p.m., Eastern Time, on May 6, 2025. The 401(k) Plan trustee will vote shares for which it has not received instructions in the same proportion as the shares for which it has received instructions. The Canada Retirement Savings Program trustee will only vote those plan shares for which voting instructions are received prior to this deadline. Participants in the Company Plans may not vote the shares owned through such plans after this deadline, including at the Annual Meeting.

How many shares must be present to hold the 2025 Annual Meeting?

In order for us to lawfully conduct business at our 2025 Annual Meeting, a majority of the shares outstanding and entitled to vote as of March 7, 2025 must be present or represented by proxy. This is referred to as a quorum. Your shares are counted as present at the meeting if you attend the 2025 Annual Meeting and vote during the meeting or if you properly return a proxy by Internet, by telephone, or by mail in advance of the meeting and do not revoke the proxy. If a quorum is not present, the meeting may be adjourned from time to time until a quorum is present.

Will my shares be voted if I do not provide my proxy or instruction card?

Registered Shareholders

If your shares are registered in your name, your shares will not be voted unless you provide a proxy by internet, telephone or mail, or vote during the 2025 Annual Meeting.

Plan Participants

If you are a participant in one of our employee 401(k) or defined contribution plans and you do not provide timely instructions to the plan trustee, shares allocated to your account(s) will be voted by the plan trustee depending on the terms of your plan and other legal requirements.

Beneficial Owners

If you hold shares through an account with a broker and you do not provide voting instructions, under NYSE rules, your broker may vote your shares on routine matters only. The ratification of the appointment of Ernst & Young LLP (Proposal 3) is considered a routine matter, and your nominee can therefore vote your shares on that proposal even if you do not provide voting instructions. Proposals 1, 2, 4 and 5 are not considered routine matters, and your nominee cannot vote your shares on these proposals unless you provide voting instructions. Votes withheld by brokers in the absence of voting instructions from a beneficial owner are referred to as “broker non-votes.”

Multiple Forms of Ownership

The Company cannot provide a single proxy or instruction card for shareholders who own shares in different forms of accounts (employee benefit plan shares, registered shares, and beneficially-owned shares). As a result, if your shares are held in multiple types of accounts, you must submit your votes for each type of account in accordance with the instructions you receive for that account.

What is the vote required for each proposal?

For Proposal 1, Election of Director Nominees, each director nominee for whom more shares are voted “for” than “against” his or her election will be elected as a director at the meeting. Under our Bylaws, if more votes are cast “against” than are cast “for” a nominee, the nominee shall offer his or her resignation. The independent members of the Board will determine and promptly publicly announce the action to be taken with respect to acceptance or rejection of the resignation offer.

For each of Proposal 2, Advisory Vote to Approve Named Executive Officer Compensation, Proposal 3, Ratification of Appointment of Ernst & Young LLP as Independent Registered Public Accounting Firm for 2025, Proposal 4, Approval of Amendments to our Articles of Incorporation to Eliminate Supermajority Voting Requirements, and Proposal 5,

​

​

Table of Contents

Shareholder Proposal Regarding Simple Majority Voting Requirements, the proposal will be approved if more votes are cast “for” than are cast “against” the proposal. Proposals 2 and 3 are advisory and nonbinding. The Board will review the voting results on these proposals and take the results into account when making future decisions regarding these matters. “Votes cast” exclude abstentions and broker non-votes.

What is the effect of an abstention?

A shareholder who abstains on some or all matters is considered present for purposes of determining if a quorum is present at the 2025 Annual Meeting, but an abstention is not counted as a vote cast. An abstention has no effect for the vote on any proposal.

What is the effect of a broker non-vote?

Broker non-votes will be counted for purposes of calculating whether a quorum is present at the 2025 Annual Meeting, but will not be counted for purposes of determining the number of votes present in person or represented by proxy and entitled to vote with respect to a particular proposal. Thus, a broker non-vote will not impact our ability to obtain a quorum, will not affect the outcome with respect to the election of directors, and will not otherwise affect the outcome of the vote on a proposal that requires the affirmative vote of a majority of the votes cast on the proposal.

Who will count the votes?

A representative of Broadridge Financial Services will tabulate the votes and act as independent inspector of election for the 2025 Annual Meeting.

Where can I find the voting results of the 2025 Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting. The final voting results will be tallied by the inspector of election and disclosed by the Company in a Current Report on Form 8-K filed with the SEC within four business days following the 2025 Annual Meeting.

What is “householding” and how does it affect me?

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, we send only one Annual Report and Proxy Statement to eligible shareholders who share a single address, unless we have received instructions to the contrary from any shareholder at that address. The practice is designed to reduce our printing and postage costs. Shareholders who participate in householding will continue to be able to separately vote their proxies. We do not use householding for any other shareholder mailings, such as dividend checks, Form 1099s, or account information statements.

If you are eligible for householding, but received multiple copies of our Annual Report and Proxy Statement and prefer to receive only a single copy for your household, please contact Equifax Inc., Attn: Office of Corporate Secretary, P.O. Box 4081, Atlanta, Georgia 30302, telephone (404) 885-8000. If you are a registered shareholder residing at an address with other registered shareholders and wish to receive a separate Annual Report or Proxy Statement at this time or in the future, we will provide you with a separate copy. To obtain this copy, please contact the Office of Corporate Secretary. If you own shares through a broker, bank or other nominee, you should contact the nominee concerning householding procedures.

The Company cannot provide a single proxy or voting instruction card for shareholders who own shares in different forms of accounts (employee benefit plan shares, registered shares, and beneficially-owned shares). Accordingly, you will receive a separate solicitation and proxy for each type of account in which shares are held and you must submit your votes for each type of account in accordance with the instructions received for that account.

Can I receive a copy of the Annual Report?

Yes. We will provide a copy of our Annual Report without charge, upon written request, to any registered or beneficial owner of common stock entitled to vote at the 2025 Annual Meeting. Requests should be made in writing addressed to the Equifax Inc., Attn: Office of Corporate Secretary, P.O. Box 4081, Atlanta, Georgia 30302, or by calling (404) 885-8000.

Can I view the Proxy Statement and Annual Report on the Internet?

Yes. The Proxy Statement and Annual Report are available on the internet at https://investor.equifax.com/financial-information/annual-reports-and-proxy-statements. Most shareholders will receive their annual meeting materials via

​

​

Table of Contents

electronic delivery. The SEC also maintains a website at https://www.sec.gov that contains reports, proxy statements and other information regarding Equifax.

Can I choose to receive the Proxy Statement and Annual Report on the internet instead of receiving them by mail?

Yes. If you are a registered shareholder or beneficial owner, you can elect to receive future annual reports and proxy statements on the internet only and not receive copies in the mail by following the instructions on your proxy card or voting instruction form. Your request for electronic transmission will remain in effect for all future annual reports and proxy statements, unless withdrawn. Most active employees who participate in the Company’s savings plans will receive an online notification announcing Internet availability of the annual report and proxy statement; a paper copy will not be provided unless requested by following the instructions in the email notification.

Who pays the cost of this proxy solicitation?

The Company has retained Innisfree M&A Incorporated to assist in soliciting proxies for an annual fee of $25,000 plus expenses, and will bear the cost of soliciting proxies. Directors, officers and other Company associates also may solicit proxies by telephone or otherwise. Brokers and other nominees will be requested to solicit proxies or authorizations from beneficial owners and will be reimbursed for their reasonable expenses.

How do I recommend a director nominee or submit a proposal or director nominee for the 2026 Annual Meeting of Shareholders?

The Governance Committee will consider for possible nomination qualified Board candidates that are submitted by our shareholders using the same process that applies to candidates identified by other sources. Shareholders wishing to make such a submission may do so by sending the following information to the Governance Committee no later than [ ] and no earlier than [ ], c/o Equifax Inc., Attn: Office of Corporate Secretary, P.O. Box 4081, Atlanta, Georgia 30302: (1) a nomination notice in accordance with the procedures set forth in Section 1.12 of our Bylaws; (2) a request that the Governance Committee consider the shareholder’s candidate for inclusion in the Board’s slate of nominees for the applicable meeting; and (3) along with the shareholder’s candidate, an undertaking to provide all other information the Committee or the Board may request in connection with their evaluation of the candidate. A copy of our Bylaws is available on our website at www.equifax.com/about-equifax/corporate-governance or by writing to the Corporate Secretary.

Any shareholder’s nominee must satisfy the minimum qualifications for any director described above in the judgment of the Governance Committee and the Board. In evaluating shareholder nominees, the Governance Committee and the Board may consider all relevant information, including the factors described above, and additionally may consider the size and duration of the nominating shareholder’s holdings in the Company; whether the nominee is independent of the nominating shareholder and able to represent the interests of the Company and its shareholders as a whole; and the interests and/or intentions of the nominating shareholder.

Shareholders may also submit proposals and director nominations through our proxy access procedures for consideration at the 2026 Annual Meeting, including proposals submitted for inclusion in the Company’s proxy materials for the 2026 Annual Meeting. Notice of such proposals or director nominations must be delivered to us no later than [ ] (and, in the case of a director nomination pursuant to proxy access, no earlier than [ ]). The proposal or director nomination must satisfy the information and other requirements specified in our Bylaws and, if to be included in our proxy materials for the 2026 Annual Meeting, must comply with SEC Rule 14a-8 and other applicable rules and interpretations of the SEC.

Any shareholder proposal or director nomination submitted to the Company in connection with the 2026 Annual Meeting should be addressed to the Corporate Secretary at the address above. In addition, the shareholder proponent or a duly authorized representative must appear in person at the 2026 Annual Meeting to present the proposal.

In addition to satisfying the foregoing advance notice requirements under our Bylaws, to comply with the universal proxy rules under the Securities Exchange Act of 1934, shareholders 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 Securities Exchange Act of 1934.

ANNEX A:

Reconciliation of Non-GAAP Financial Measures

We refer in this Proxy Statement to Adjusted EPS and Adjusted EBITDA, which are non-GAAP financial measures.

Adjusted EPS attributable to Equifax is diluted EPS attributable to Equifax, defined as net income adjusted for acquisition-related amortization expense, accrual for legal and regulatory matters related to the 2017 cybersecurity incident, fair market value adjustment and gain on sale of equity investments, pension mark-to-market fair value adjustment, foreign currency impact of certain intercompany loans, acquisition-related costs other than acquisition amortization, realignment of resources and other costs, income tax effect of stock awards recognized upon vesting or settlement, Argentina highly inflationary foreign currency adjustment, adjustments to deferred tax balances, reversal of a valuation allowance for certain deferred tax assets, legal settlement, and aggregated tax impact of these adjustments.

Adjusted EBITDA is defined as net income excluding income taxes, interest expense, net, depreciation and amortization expense, accrual for legal and regulatory matters related to the 2017 cybersecurity incident, fair market value adjustment and gain on sale of equity investments, pension mark-to-market fair value adjustment, foreign currency impact of certain intercompany loans, acquisition-related costs other than acquisition amortization, realignment of resources and other costs, Argentina highly inflationary foreign currency adjustment and legal settlement.

Adjusted EPS and Adjusted EBITDA are provided to show the performance of our core operations without the effect of the excluded items, consistent with how our management reviews and assesses our historical performance when measuring operating profitability, evaluating performance trends and setting performance objectives. This non-GAAP measure is not a measurement of financial performance under GAAP and should not be considered as an alternative to EPS, and may not be comparable to non-GAAP financial measures used by other companies.

The following table reconciles Adjusted EPS to net income attributable to Equifax, the most directly comparable financial measure calculated in accordance with GAAP:

Notes to Reconciliation of Non-GAAP Financial Measures to the Comparable GAAP Financial Measures

Acquisition-related amortization expense – For the years ended December 31, 2024 and 2023, we recorded acquisition-related amortization expense of certain acquired intangibles of $261.1 million ($207.5 million, net of tax) and $250.7 million ($201.9 million, net of tax), respectively. We calculate this financial measure by excluding the impact of acquisition-related amortization expense and including a benefit to reflect the material cash income tax savings resulting from the income tax deductibility of amortization for certain acquired intangibles. These financial measures are not prepared in conformity with GAAP. Management believes excluding the impact of amortization expense is useful because excluding acquisition-related amortization, and other items that are not comparable allows investors to evaluate our performance for different periods on a more comparable basis. Certain acquired intangibles result in material cash income tax savings which are not reflected in earnings. Management believes that including a benefit to reflect the cash income tax savings is useful as it allows investors to better value Equifax. Management makes these adjustments to earnings when measuring profitability, evaluating performance trends, setting performance objectives and calculating our return on invested capital.

Accrual for legal and regulatory matters related to the 2017 cybersecurity incident – Accrual for legal and regulatory matters related to the 2017 cybersecurity incident includes legal fees to respond to subsequent litigation and government investigations for the periods presented. For the year ended December 31, 2024, we recorded an accrual for legal and regulatory matters related to the 2017 cybersecurity incident of $0.3 million ($0.2 million, net of tax). For the year ended December 31, 2023, we recorded an accrual for legal and regulatory matters related to the 2017 cybersecurity incident of $16.8 million ($16.7 million, net of tax). Management believes excluding these charges is useful as it allows investors to evaluate our performance for different periods on a more comparable basis. Management makes these adjustments to net income when measuring profitability, evaluating performance trends, setting performance objectives and calculating our return on invested capital. This is consistent with how management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Fair market value adjustment and gain on sale of equity investments – For the year ended December 31, 2023, we recorded a $13.4 million ($8.8 million, net of tax) gain related to adjusting our investment in Brazil to fair value at the date of the acquisition and gain related to the sale of an equity method investment. On August 7, 2023, we purchased the remaining interest of our equity investment in Brazil. The investment in Brazil had a readily determinable fair value and the carrying value of the investment was adjusted to fair value as of the close date, resulting in a loss. Management believes excluding these charges from certain financial results provides meaningful supplemental information regarding our financial results for the twelve months ended December 31, 2023, since the non-operating gains or losses are not comparable among the periods. This is consistent with how our management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Pension mark-to-market fair value adjustment – We utilize a mark-to-market method of accounting for recognizing actuarial gains and losses and expected return on plan assets for our defined benefit pension and other postretirement benefit plans. Under our accounting methodology for recognizing actuarial gains and losses and expected return on plan assets for our defined benefit pension and other postretirement benefit plans, remeasurement of projected benefit obligation and plan assets are immediately recognized in earnings through net periodic benefit cost within Other Income (Expense) on the Consolidated Statements of Income, with pension and postretirement plans to be remeasured annually in the fourth quarter, or on an interim basis as triggering events require remeasurement. For the year ended December 31, 2024, we recorded an $11.6 million ($8.7 million, net of tax) loss related to the mark-to-market fair value adjustment of our pension and postretirement benefit plans. For the year ended December 31, 2023, we recorded a $0.1 million ($0.1 million, net of tax) loss related to the mark-to-market fair value adjustment of our pension and postretirement benefit plans. Management believes excluding these charges from certain financial results provides meaningful supplemental information regarding our financial results, since the non-operating gains and losses are not comparable among the periods. This is consistent with how our management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Foreign currency impact of certain intercompany loans – For the year ended December 31, 2024, we recorded a foreign currency loss related to certain intercompany loans of $0.4 million. For the year ended December 31, 2023, we recorded a $1.0 million foreign currency gain related to certain intercompany loans. The impact was recorded to the Other

Income (Expense), net line item within the Consolidated Statements of Income. Management believes excluding this charge is useful as it allows investors to evaluate our performance for different periods on a more comparable basis. This is consistent with how management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Acquisition-related costs other than acquisition amortization – For the year ended December 31, 2024, we recorded $68.4 million ($51.8 million, net of tax) for acquisition-related costs other than acquisition amortization. For the year ended December 31, 2023, we recorded $103.2 million ($79.5 million, net of tax) for acquisition-related costs other than acquisition amortization. These costs primarily related to transaction and integration costs resulting from recent acquisitions and were recorded in operating income. Management believes excluding this charge from certain financial results provides meaningful supplemental information regarding our financial results, since a charge of such an amount is not comparable among the periods. This is consistent with how our management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting, and analyzing future periods.

Charge related to the realignment of resources and other costs – During the year ended December 31, 2024, we recorded $48.0 million ($34.1 million, net of tax) of restructuring charges related to the realignment of resources and other costs. These restructuring charges predominantly relate to our ongoing efforts toward completion of our technology transformation in order to support the Company's strategic objectives. For the year ended December 31, 2023, we recorded $34.6 million ($24.6 million, net of tax) of restructuring charges for the realignment of resources and other costs. These restructuring charges predominantly related to the reduction of headcount and contract terminations in order to support the Company’s strategic objectives and increase the integration of our global operations. Management believes excluding this charge from certain financial results provides meaningful supplemental information regarding our financial results for the twelve months ended December 31, 2024 and 2023, since the charges are not comparable among the periods. This is consistent with how our management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Income tax effects of stock awards that are recognized upon vesting or settlement – For the year ended December 31, 2024, we recorded a tax benefit of $8.2 million related to the tax effects of deductions for stock compensation in excess of amounts recorded for compensation costs. For the year ended December 31, 2023, we recorded a tax benefit of $3.4 million related to the tax effects of deductions for stock compensation in excess of amounts recorded for compensation costs. Management believes excluding this tax effect from financial results provides meaningful supplemental information regarding our financial results for the twelve months ended December 31, 2024, as compared to 2023, because these amounts are non-operating and relate to income tax benefits or deficiencies for stock awards recognized when tax amounts differ from recognized stock compensation cost. This is consistent with how management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Argentina highly inflationary foreign currency adjustment – Argentina experienced multiple periods of increasing inflation rates, devaluation of the peso, and increasing borrowing rates. As such, Argentina was deemed a highly inflationary economy by accounting policymakers. For the year ended December 31, 2024, we recorded a $1.1 million foreign currency loss related to the impact of remeasuring the peso denominated monetary assets and liabilities as a result of Argentina being a highly inflationary economy. During the year ended December 31, 2023, we recorded a foreign currency loss of $3.8 million. Management believes excluding this charge is useful as it allows investors to evaluate our performance for different periods on a more comparable basis. This is consistent with how management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Adjustments to deferred tax balances – During the year ended December 31, 2023, we recorded a tax benefit of $27.2 million related to the write off of a deferred tax liability related to our original investment in Boa Vista Serviços as a result of our purchase of the remaining interest in Boa Vista Serviços in the third quarter of 2023. We determined the deferred tax balance should no longer be recorded as a result of our purchase of the remaining interest in Boa Vista Serviços during the third quarter of 2023. Management believes excluding this tax effect from certain financial results provides meaningful supplemental information regarding our financial results for both periods since this adjustment is not comparable among the periods. This is consistent with how management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Reversal of a valuation allowance for certain deferred tax assets – For the year ended December 31, 2024, we recorded a full reversal of a valuation allowance for certain deferred tax assets of $4.6 million. The valuation allowance was initially recorded in the first quarter of 2020 for deferred tax assets where the benefit was not expected to be realized. In the fourth quarter of 2024, we determined the benefit is expected to be realized for the deferred tax assets and

​

therefore we fully reversed the valuation allowance initially recorded. The tax effect of the initial valuation allowance recorded was excluded from financial results in the first quarter of 2020, and therefore the tax effect of the reversal of the valuation allowance has been excluded from financial results in the fourth quarter of 2024. Management believes excluding this tax effect from financial results provides meaningful supplemental information regarding our financial results for the twelve months ended December 31, 2024 because this amount is not comparable among the periods. This is consistent with how management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Legal settlement – For the year ended December 31, 2024, we recorded a $15.0 million charge for a settlement associated with the resolution of a matter with the CFPB. Management believes excluding this charge from certain financial results provides meaningful supplemental information regarding our financial results for the year ended December 31, 2024, since a charge of such an amount is not comparable among the periods. This is consistent with how our management reviews and assesses Equifax’s historical performance and is useful when planning, forecasting and analyzing future periods.

Adjusted EBITDA and EBITDA margin – Management defines adjusted EBITDA as consolidated net income attributable to Equifax plus net interest expense, income taxes, depreciation and amortization, and also excludes certain one-time items. Management believes the use of adjusted EBITDA and adjusted EBITDA margin allows investors to evaluate our performance for different periods on a more comparable basis.
