EFX.AI: Powering the FutureThe talents of our global team and differentiated data that only Equifax can provide areour greatest assets. Unique and proprietary data is the foundation of our Equifax AIData Moat. In an era of standardized AI engines, most AI tools rely on publicly-availablemarket data for use in AI models. When AI tools are a shared resource, the data isthe difference. We believe that AI will have a more profound impact than previoustechnology milestones over the past 50 years, such as the personal computer in the1980s or the internet in the 1990s. While many companies are expected to be disruptedor disintermediated by AI, Equifax is leveraging AI to disrupt the industry with higherperforming,AI-driven solutions fueled by proprietary data. Only Equifax can access ourscale, proprietary data assets for AI and delivery to our customers. This unique datadifferentiates us in the industry and positions us to leverage our unique and differentiateddata and EFX.AI for ongoing innovation and growth in an AI-forward business environment.The Equifax Cloud and our custom data fabric were purpose-built to maintain andmanage the large volume of diverse, proprietary datasets needed to maximize AIperformance. If data is the “new oil,” then the Equifax single data fabric is both therefinery and the pipeline that allows us to turn OnlyEquifax data into high-qualityfuel for our customers. That fuel is amplified by EFX.AI across our proprietary data.Only Equifax can use this data for the development of customer solutions and new productsusing our patented EFX.AI technology. The moat around our data – the protection weprovide to ensure that our data can only be used by our customers on a permissionedor aggregated basis and not blended with public, untrusted sources – is critical.The EquifaxData MoatAI requires deep,accurate, and highqualitydata. TheEquifax data fabricingests 20 billionrecords per monthglobally while alsoenabling us to managethat data in keepingwith regulatoryrequirements.The Work Number® Database209 million active employment records and 813million total employment records for verificationsof employment and income from approximately4.9 million different U.S. employers.Relationship with the NationalConsumer Telecom and UtilitiesExchange, Inc.® (NCTUE®)Operation and management of the U.S.NCTUE database that includes more than430 million telecommunications, pay TV,internet, home security, and utility accountrecords and their associated payments.Commercial Financial NetworkNearly 200 million U.S. commercial tradelinesacross almost 79 million businesses.Core Credit Unique, high-quality data is a performance multiplier for AI and the Equifax AI Data Moat.In 2025, some of our differentiated, non-public data in the U.S. included:More than 3.6 billion U.S. tradelines with over1.6 billion updates monthly to currently reportedaccounts. The U.S. consumer credit file includescontributions from over 15,000 data furnishers.DataX and TeletrackAccess to more than 120 million unbanked,underbanked, and credit rebuilding consumers –enabling greater access to credit.

In 2025, approximately 90% of our record $6.075 billion in revenue was generatedthrough the direct sale of, or through products generated from, proprietarydata unique to Equifax. Our powerful combination of proprietary data and patentedEFX.AI technology drove a record more than 180 NPIs and 2025 Vitality Index (definedas percentage of revenue from new products introduced in the last three years) of15% which was 50% above our Long-Term goal of 10%.We have tripled the number of products launched using EFX.AI since 2023, and in 2025,100% of our new models and scores were powered by EFX.AI. These new AI-drivenmodels provided a remarkable nearly 30% performance lift over legacy models – aperformance improvement that demonstrates that our AI strategy is not only scaling,but providing the superior predictive value required to lead the market.Expanding AI Across Equifax With AI 4 EFXand Our E3 Strategic Operations PlanWhile we are incredibly proud of how we’re delivering higher-performing, EFX.AIpoweredinnovation to help our customers grow, we are equally energized by theoperational efficiencies gained through our new internal AI 4 EFX initiative. AI 4 EFX,enabled by the Equifax Cloud, is focused on the powerful ways that we’re usingAI internally to spend less time on routine items and more time on the complex,creative, and collaborative challenges that drive the New Equifax forward.ExcellenceInvesting deeply in our people.Providing continuous AI upskilling,new learning opportunities,and clear career paths. It’sabout empowering creativityand growing the best talent inthe industry, which, in turn, helpsus better serve our customersand consumers.EffectivenessHow we elevate our impact.We are focused on deliveringinnovative solutions andsuperior service that createsmaximum value for customersand consumers.EfficiencyWorking smarter. Being AIforwardmeans leveraging AI anddeploying AI agents to handleroutine tasks, and empoweringour people to focus on the moststrategic, creative, and fulfillingparts of their jobs.As we implement our E3 Operations plan, we are focused on improving our consumerand customer call centers with AI-enabled and AI-assisted call processes and drivingmeaningful efficiencies. Recent initiatives include the use of a virtual agent in ourU.S. call center that allows sensitive tasks like consumer credit freezes to be handledthrough intuitive, secure conversations. The virtual agent integrates with our callcenter technology to leverage the skilled expertise of human agents when required.This process decreases wait times, speeds time to resolution, and improves theconsumer experience. This AI call center transformation and broad deployment of AIagents demonstrates our ability to fundamentally reimagine labor-intensive workflowsand serves as a template for broader workforce productivity gains. Over the next3 years, we expect to drive towards $75 million of annual cost savings from our E3strategic plan.1 2 3 Core to AI 4 EFX is E3, a 3-year strategic Operations plan unique to Equifax that we expect todeliver approximately $75 million of savings. E3 is built on 3 pillars:100% of our newmodels and scoreswere powered byEFX.AI. These newAI-driven modelsprovided a nearly 30%performance lift overlegacy models.

AI is also driving technology efficiency. It further enables us to drive more softwareoutput from the same engineering investment, with nearly 4,000 software engineersusing AI coding tools. In January 2026, our Technology team produced more than 6million lines of AI-generated code.AI is being leveraged across the entire software development lifecycle frominformation gathering and requirements planning through coding, testing,deployment, monitoring, and data management to transform how we build, protect,and deploy products.By automating coding and maintenance, we are delivering:Accelerated DevelopmentAI now assists with real-time codingand complex system updates,allowing engineers to move fasterfrom concept to feature. Weare accelerating coding velocity,automatically generating unit tests,and deploying virtual developeragents for routine tasks. AI-poweredknowledge retrieval immediatelytranslates unstructured designs intoclear requirements, while automatedroadmap and requirements toolingensures strong alignment betweenengineering and product strategy.Built-in Quality and SecurityWe have automated the creationof rigorous tests and code reviews,helping to quickly detect potentialissues. AI-powered test generationand quality engineering toolsembed quality checks directlyinto the development workflow,achieving 30% AI test coverage,while automated data quality agentsgenerate syntactically perfect codefor data frameworks. This helps toensure data accuracy and reliabilityof data.Operational ResilienceIn the event that a softwaredeployment issue occurs, AI-drivendiagnostics help to identify theroot cause and execute recoverysteps instantly to reduce systemdowntime. These capabilities havedriven a 41% reduction in incidents,and a change failure rate of under2% versus an industry standard ofunder 5%. Predictive observabilitycapabilities forecast potential issuesbefore they occur and significantlylower Mean Time to Resolution –the time it takes for the team to fullyresolve a system issue from themoment it is first reported.More efficient code generation enables our technology talent to focus on high-valueinnovation rather than routine tasks. As we continue to scale adoption in 2026, weexpect these gains to compound for even faster product delivery, accelerated responsetimes to market opportunities, and improved return on spend. AI will create capacityand speed in our Technology team, as we continuously integrate new AI capabilities atevery stage of the development lifecycle.Embedding AI across our software development lifecycle is critical in our evolutionto Agentic Engineering. Our Agentic AI Platform, slated for full production release in2026, is accelerating and standardizing the development, deployment, monitoring, andgovernance of AI agents across our business. Equifax has built a unified foundation forsecurity, compliance, and deployment monitoring. By aligning this platform with theNational Institute of Standards and Technology (NIST) AI Risk Management Framework,we have ensured that security and responsibility are not obstacles to speed, butdrivers of it. This secure-by-design architecture allows us to move from siloed effortsto “build once, deploy everywhere” economics.Importantly, we have also leveraged AI and automation to enhance our security,upgrading our ability to not only triage and remediate potential threats, but toaccelerate the critical security decisions that drive business delivery. In 2025, we usedAI and automation to streamline our Security Operations Center and auto-resolveOur Agentic AIplatform is alignedwith the NIST AIRisk Managementframework. Securityand responsibilityare not obstaclesto speed, but driversof it.

Our internal security culture was reinforced throughan AI-powered platform that delivered personalized training to our workforce,validated by over 240,000 phishing simulations. We also successfully defendedagainst AI threats. As cybercriminals adopted AI-enabled tools to create highlyrealistic deepfake impersonations and launch more complex attacks, we recalibratedour defenses.With almost 90% of our global employees and contractors leveraging AI tools in 2025,it has been deeply embedded in our organization.Securing Our Enterprisefor AI Use by Every EmployeeGlobal Equifax employees have instant accessto a pre-approved list of enterprise-ready AItools to accelerate innovation and streamlinetheir workflows. As new features are released,we selectively pause them until they meetEquifax security standards and controls. Wecontinuously restrict high-risk external modelsthat do not align with our requirements.Leveraging AI within our HumanResources talent lifecycle,including the use of thetechnology alongside employeeinput about skills and careeraspirations, to help them visualizeindividualized career paths anddiscover new opportunities.LegalDeveloping AI tools in our Legalteam to quickly and securelyanalyze contracts and report oncontract status.FinanceDecreasing manual processingtimes in our Finance department’sAccounts Payable process byusing AI to classify and extractrelevant data from invoices.We saw deployment and benefits from AI tools ramp rapidly as we expanded newcapabilities across our team. As our workforce and developers embraced AI todrive innovation, we ensured that they could do so securely. We built the necessaryguardrails – from automated content safety filters to secure coding frameworks –that allowed our teams to adopt powerful new tools while taking precautions toprotect the enterprise from potential data leakage or unmanaged risk.Ensuring That AI Models AreSafe and That Business Data IsProtected Is CriticalWe have designed our architecture so that wenever rely solely on an AI model provider toprotect our data – implementing an agnosticcontrol layer that sits between our employeesand the AI. This layer sanitizes prompts andresponses, checking for sensitive data beforeit reaches the AI model.

fuller insights are designed to help more Americans live their financial best and achieve the American dream of homeownership. Offering VantageScore 4.0 mortgage credit scores for $1 provides a 90% savings over lenders’ current mortgage credit score costs. This move builds on the February 2026 economic benefits study from credit risk research company Deep Future Analytics which quantified the impact of Federal Housing Finance Agency (FHFA) Director Bill Pulte’s July 2025 decision to authorize VantageScore 4.0 for competitive use in GSE-conforming mortgages. More than 200 Equifax mortgage lender customers were testing or in production with VantageScore 4.0 at the end of 2025 given the significant cost savings opportunity. We are committed to providing consumers with the resources that they need to increase their financial capability. In 2025, we continued to expand the services we provide to help people better understand their personal finances and the credit system. Examples included: Further supporting the needs of our 30.3 million myEquifax® users in the U.S. with the launch of a new myEquifax mobile application that gives people a convenient way to monitor their financial health from mobile devices.
