Part I

Corporate History

FactSet Research Systems Inc. and its wholly-owned subsidiaries ("we," "our," "us," the "Company" or "FactSet") was founded in 1978 and has been publicly traded since June 1996. We are dual-listed on the New York Stock Exchange ("NYSE") and the Nasdaq Stock Market ("Nasdaq") under the symbol "FDS". FactSet has been a member of the S&P 500 since December 2021.

Business Overview

FactSet is a global data and artificial intelligence ("AI") solutions provider to the financial markets with open and flexible technologies that deliver financial intelligence to finance professionals worldwide.

Our platform delivers expansive data, sophisticated analytics, and flexible, AI-powered technologies used by global financial professionals to power their critical investment, dealmaking and advisory workflows. As of August 31, 2026, we had more than 9,200 clients and over 260,000 professionals using our solutions, including institutional asset managers, bankers, wealth managers, asset owners, partners, hedge fund professionals, corporate users, private equity and venture capital professionals, and market infrastructure participants. Our revenues are primarily derived from subscriptions to our multi-asset class data and solutions that include workstations, portfolio analytics, enterprise data solutions, and AI solutions. We also offer managed services that operate as an extension of our clients' internal teams to support data, performance, risk and reporting, and AI-enabled workflows.

We drive our business based on a detailed understanding of our clients’ workflows. We provide financial data and market intelligence on securities, companies, industries and people to enable our clients to research advisory, dealmaking and investment ideas and analyze, monitor and manage their portfolios. Our solutions for institutional buyside clients span the investment lifecycle of investment research, portfolio construction and analysis, trade execution, performance measurement, risk management and reporting. Our banking solutions facilitate company and market research, enabling clients to perform fundamental analysis, generate ideas, and build and distribute presentations through proprietary and third-party databases with global coverage of public and private markets, granular industry metrics, and deep historical data. Our wealth solutions support home office, advisory, and client engagement workflows, providing financial advisors with tools to monitor markets and their book of business, prospect for new clients, and generate proposals, while enhancing existing client relationships and improving firm-wide efficiency across the investment portfolio lifecycle. We provide open and flexible data and technology offerings, including a configurable desktop and mobile platform, comprehensive data solutions, cloud-based digital solutions, application programming interfaces ("APIs"), and model context protocol ("MCP") servers. AI is embedded throughout these offerings to enhance data discovery, automate routine workflows and improve the speed and accuracy of client insights. Our platform and solutions are supported by our client success and service teams.

We operate our business through three reportable segments ("segments"): the Americas, EMEA and Asia Pacific. Within each segment, we offer a range of products, data, managed services, and analytical applications which can be tailored to a wide range of workflows.

Segments

Our segment revenues are based on the geographic region where our clients contract with us:

• Americas: The Americas segment primarily sells to clients in North, Central and South America. In the Americas, we have offices in eight states in the United States ("U.S."). Additionally, we have data centers in two states in the U.S. and an office in each of Brazil and Canada. Revenues from the Americas represented 65% of total revenues during fiscal 2026.

• EMEA: The EMEA segment primarily sells to clients in Europe, the Middle East and Africa via offices in Bulgaria, France, Germany, Italy, Latvia, Luxembourg, the Netherlands, Sweden, the United Arab Emirates and the United Kingdom ("UK"). Revenues from EMEA represented 24% of total revenues during fiscal 2026.

• Asia Pacific: The Asia Pacific segment primarily sells to clients in Asia and Australasia via office locations in Australia, China, Hong Kong Special Administrative Region ("SAR") of China, India, Japan, the Philippines and Singapore. Revenues from Asia Pacific represented 11% of total revenues during fiscal 2026.

Refer to Part II, Item 8. Note 16, Segment Information, in the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K for more information on our segments.

Products and Solutions

We deliver trusted, connected financial data, software applications, advanced analytics, and AI-powered solutions embedded in the critical workflows that finance professionals rely on every day. We serve a diverse array of clients in over 80 countries and a wide range of verticals, ranging from the largest global financial services firms with multiple business lines to smaller and independent firms. Our clients include institutional asset managers, asset owners, hedge funds, investment banks, wealth managers, private equity and venture capital firms, corporations, and market infrastructure participants.

As our clients’ needs vary, we tailor our data and technology to become an integral component of the workflows that drive their decision-making. Clients access our capabilities in the form that best fits their operating model, whether through software applications, data feeds and APIs, or managed services. Many clients use our capabilities in more than one form, combining our data and applications with their own workflows and systems.

Underpinning these workflows is a broad and expanding set of financial markets data, including client-owned data, that we ingest, map, normalize, and structure. Our mapping links entities, securities, and identifiers across our content allowing our clients to integrate our data with their own. We also deliver our content in forms designed for machine consumption, including the metadata and symbology that allow AI agents and other automated systems to interpret and act on it. In addition, through our CUSIP Global Services ("CGS") business, operating on behalf of the American Bankers Association, we support security master files and serve as the exclusive issuer of Committee on Uniform Security Identification Procedures ("CUSIP") and CUSIP International Number System ("CINS") identifiers globally.

Business Strategy

We strive to be a trusted enterprise partner and service provider to our clients across the financial services spectrum, delivering relevant intelligence, insights and execution solutions tailored to our clients’ business models.

To execute our strategy, we are focused on three core pillars and primary areas of investment:

• Expanding our data and analytics offerings and delivery capabilities:** We continue to expand our data and analytics to provide a comprehensive corpus of industry, proprietary, contributed, and third-party data and models. This includes granular data for key industry verticals, real-time market data, fund data and frontier unstructured data. In addition to using our growing data catalog to drive our AI-powered workstation products, we aim to continue to expand our delivery capabilities in the cloud and through other methods, including MCP, to advance our position as a leading enterprise data provider for our clients in the AI age. We aim to be a single, authoritative source by collecting, mapping, normalizing, and structuring data into formats that both professionals and AI systems can rely on.

• Transforming client workflows with AI:** Through continued innovation, we aim to help our clients re-design their core workflows with AI. This includes fundamentally re-imagining our core workstation product and building agentic solutions with specialized domain knowledge across our firm types, including investment research, performance reporting, financial modeling, pitch creation, meeting preparation, advisory client engagement, and more. We are developing the platform for clients to build, register, entitle, audit, and manage AI agents, whether developed by us, our clients, or third parties, and to intelligently route work between deterministic systems and large language model systems to optimize quality.

• Enhancing our commercial capabilities for the AI age:** We are building a suite of AI products with a focus on trusted, high-quality data, secure integration with models and workflows, and deep domain expertise. To deploy these new solutions and capture value, we are upgrading our commercial and go-to-market capabilities, including by actively moving client contracts to longer duration enterprise platform agreements that combine subscription-based minimums with consumption-based pricing components.

Revenues and Annual Subscription Value ("ASV")

We derive most of our revenues by delivering client access to our multi-asset class data and solutions powered by our platform of connected data and technology that is available over the contractual term (referred to as the "Hosted Platform"). The Hosted

Platform is a subscription-based service that provides client access to various combinations of products and services including workstations, portfolio analytics, enterprise data solutions, AI agents, and agentic workflow solutions.

We believe ASV reflects our ability to grow recurring revenues and generate positive cash flows, and thus serves as a key indicator of the successful execution of our business strategy. ASV at any point in time represents our forward-looking revenues for the next 12 months from all recurring services currently being supplied to clients. Organic ASV at any point in time equals our ASV excluding ASV from acquisitions and the comparable impact of dispositions and discontinued lines of business, effected within the last 12 months, and the impact of foreign currency movements.

FactSet Clients and Users

We had 9,258 clients and 260,671 professionals using FactSet as of August 31, 2026. Our client count includes clients with ASV of $10,000 and above. For the year ended August 31, 2026, annual ASV retention was greater than 95% and, when expressed as a percentage of clients, annual retention was 90%.

Third-Party Content

We collect and aggregate content from third-party data suppliers, news sources, exchanges, brokers and contributors into our own dedicated managed databases, which our clients access through our flexible delivery platforms. We seek to maintain contractual relationships with a minimum of two content providers for each major type of financial data, though certain data sets on which we rely have a limited number of suppliers. We make every effort to assure that, where reasonable, alternative sources are available. We have entered into third-party content agreements of varying lengths, which in some cases can be terminated with one year’s notice, at predefined dates, and in other cases on shorter notice. We are not dependent on any one third-party content supplier to meet the needs of our clients. Two suppliers each represented more than 10% of our total third-party content costs during fiscal 2026.

Data Centers and Cloud Computing

Our business is dependent on our ability to process substantial volumes of data and transactions rapidly and efficiently on our networks and systems. Our global technology infrastructure supports our operations and is designed to facilitate reliable and efficient processing and delivery of data and analytics to our clients. As part of our hybrid cloud strategy, we operate two fully redundant, physically separated data centers in the U.S. that provide client services, while also using market-leading cloud providers to run products and services to best benefit from the cloud's elasticity, resiliency, security, and regionalization. We currently use several cloud providers; however, one supplier provided the majority of our cloud computing support for fiscal 2026. Our physical data centers provide layers of redundancy to enhance system performance, including maintaining, processing and storing data at multiple locations. In the event of a single site failure or localized disaster, client workloads will automatically move to unaffected sites. We continue to focus on maintaining a global technology infrastructure that allows us to support our growing business.

Intellectual Property

We have registered trademarks and copyrights for many of our products and services and will continue to evaluate the registration of additional trademarks and copyrights as appropriate. We enter into confidentiality agreements with our employees, clients, data suppliers and vendors. We strive to protect our workflow solutions, documentation and other written materials under trade secret, copyright and patent laws. While we do not believe we are dependent on any one of our intellectual property rights, we do rely on the combination of intellectual property rights and other measures to protect our proprietary rights. Despite these efforts, existing intellectual property laws may afford only limited protection.

Research and Product Development

A key aspect of our growth strategy is to offer new solutions and enhance our existing products by making them faster and more robust with deeper data and insights. We continue to invest in AI solutions that adapt as our clients’ workflows evolve, helping professionals leverage automation, generative intelligence and dynamic analytics, while rapidly embracing new technologies to improve discoverability and usability of our products and services.

The Competitive Landscape

We are a part of the financial information services industry focused on delivering expansive data, sophisticated analytics, and flexible technology through our open platform. We offer clients comprehensive solutions with a broad set of products delivered through a desktop or mobile user interface, AI-enabled chat and agentic solutions, cloud-based platforms, standardized or bespoke data feeds, and APIs. In addition, our applications, client support and service offerings are entrenched in the workflow

of many financial professionals given the data management, portfolio analysis and screening capabilities offered. We are entrusted with significant amounts of our clients' own proprietary data, including portfolio holdings. As a result, we believe our products are central to our clients’ analysis, decision-making and operations.

We operate in a highly competitive environment. Our current competitive market is comprised of both large, well-capitalized companies and smaller, niche firms including market data suppliers, vertical AI solution providers, news and information providers, technology firms, and many third-party content providers that also supply us with financial information included in our products. The financial market data environment is competitive and includes many firms that provide products and services similar to our offerings, most notably Bloomberg L.P., S&P, London Stock Exchange Group ("LSEG"), BlackRock, MSCI Inc., and Morningstar Inc., in addition to clients with in-house teams developing their own solutions.

As a result, the Board of Directors and the Compensation and Talent Committee oversee and regularly engage with our Chief Executive Officer ("CEO"), Chief People & Workforce Transformation Officer and other senior leaders on topics such as talent attraction, talent development, retention, succession planning, compensation and benefits, workplace culture, and employee engagement. At the management level, our Chief People & Workforce Transformation Officer is responsible for leading the development and execution of the Company’s people and workforce management strategy with the support of the Company’s Executive Leadership Team.

Compensation Program

Our compensation program consists of a mix of annual salary; annual cash bonus for eligible employees, linked to Company and individual performance; and equity awards for eligible employees, designed to align their interests with our stockholders.

Well-being and Benefits

Employee wellbeing is a central component of FactSet’s people strategy. Our programs are designed to support physical, mental, and financial health while fostering a safe, inclusive, and resilient workplace. FactSet provides robust health benefits, as well as a range of wellness initiatives that support physical, emotional, social, and financial health. Policies and programs support work-life integration, including remote and hybrid work options, parental leave, and time-off programs tailored to employee needs.

Retention and Engagement

To attract and retain the talent critical to deliver on our business objectives and create sustainable growth, we foster a culture that promotes employee engagement, satisfaction, and professional development. We conduct an annual confidential employee engagement survey to assess satisfaction, gather feedback, and identify opportunities for improvement. We also invest in our employees by providing a range of training and learning programs designed to help employees advance their knowledge, skills and experience, including mentorship, leadership development programs, department-specific training, and focused upskilling.

Government Regulation

We are subject to reporting requirements, disclosure obligations and other recordkeeping requirements of the Securities and Exchange Commission ("SEC") and the various local authorities that regulate each location in which we operate. Our P.A.N. Securities, LP subsidiary is a member of the Financial Industry Regulatory Authority, Inc. and is a registered broker-dealer

under Section 15 of the Exchange Act. P.A.N. Securities, LP, as a registered broker-dealer, is subject to Rule 15c3-1 under the Exchange Act, which requires that we maintain minimum net capital requirements. We claim exemption under Rule 15c3-3(k)(2)(i).

Additional Information

Additional information with respect to our business is included in the following pages and is incorporated herein by reference:

The following risks could materially and adversely affect our business, financial condition, results of operations, and cash flows and, as a result, the trading price of our common stock could decline. These risk factors do not identify all risks that we face; our operations could also be affected by factors that are not presently known to us or that we currently consider to be immaterial to our operations. Due to risks and uncertainties, known and unknown, our past financial results may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. Investors should also refer to the other information set forth in this Annual Report on Form 10-K, including Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations and our Consolidated Financial Statements including the related Notes. Investors should carefully consider all risks, including those disclosed here, before making an investment decision.

Cybersecurity, Technology and Data Security Risks

Unauthorized access to confidential data including client data, other cyber-attacks, and the failure of our cybersecurity systems and procedures

Many of our products, as well as our internal systems and processes, involve the collection, retrieval, processing, storage and transmission of our own, as well as supplier and client, proprietary information and sensitive or confidential data through a variety of media channels. We rely on, and continuously invest in, internal processes, controls, policies, procedures and employee training programs designed to protect confidential data received in the ordinary course of business, including information from client portfolios and strategies. However, these measures do not guarantee security, and improper access to or release of confidential information may still occur—whether due to employee error or malfeasance, system error, inadvertent release, failure to properly purge or protect data, or through cyber-attacks.

Our size, scale and role in the financial markets increase our exposure to cyber-attacks and other cybersecurity risks. We and the third-party service providers we rely on for certain critical functions are subject to system failures, security breaches and cyber-attacks - including those sponsored by nation-states, terrorist organizations, or others seeking to illicitly obtain technology or intellectual property - as well as to fraud or malice by employees or vendors, human error, software or hardware failures, and the risks associated with our use of mobile and cloud technologies. These threats take many forms, including the use of generative and agentic AI, phishing, hacking, viruses, denial of service attacks, tampering, intrusions, physical break-ins, ransomware and malware.

Cyber-attacks continue to evolve in sophistication, frequency and volume, including as threat actors exploit generative and agentic AI to discover and exploit vulnerabilities at unprecedented speed and scale, and may be difficult to detect for long periods of time. Our protective measures, and those of the third parties to which we are connected, may not be effective, and a failure by our clients or third-party providers to notify us of an incident in a timely manner could delay our response and increase the resulting harm. As a result, we may not be able to anticipate, prevent or detect all attacks, and we are exposed to heightened risks of cyber-attacks or other security incidents. In addition, future advances in computing, including quantum computing, could weaken or render obsolete the encryption and other security measures on which we and our third parties rely, including through the potential future decryption of data captured today.

We also make acquisitions periodically, and we may inherit cybersecurity risks when these acquisitions are integrated into our infrastructure. Although we conduct due diligence during acquisition processes, acquired businesses may not have invested as heavily in security measures and technology, and this may introduce additional security risk.

We make a range of commitments to our clients regarding our security practices and posture, and if we do not adequately implement and enforce them, we could be in violation of those commitments. Cyberattacks, security breaches or third-party reports of perceived vulnerability, even if no breach has occurred, could damage our brand and reputation, result in litigation, regulatory actions, loss of client confidence and increased legal liability. While we maintain insurance intended to address certain cybersecurity and data protection risks, it may not cover all or the majority of the costs, losses or types of claims. We maintain, and continue to invest in, a cybersecurity program designed to identify, prioritize and mitigate these risks, including a multi-year strategy to further enhance our security posture, controls and resiliency and to remediate control gaps as they are identified. As threats continue to evolve, we must devote additional resources to modify and enhance our systems and processes, including patch and vulnerability management, and these efforts may not be completed on the timeframe we anticipate, may require significant additional investment, and may not be sufficient to prevent or mitigate every cyberattack or security incident.

A prolonged or recurring outage and other business continuity disruptions could result in a reduced or total loss of service; the loss of clients and adverse impact on our reputation

Our clients rely on us for the delivery of time-sensitive, accurate, complete and up-to-date data and applications. Our business is dependent on our ability to process substantial volumes of data and transactions rapidly and efficiently on our computer-based networks, database storage facilities, and other network infrastructure, which are located across multiple facilities globally. If we experience significant growth of our client base, increases in the number of products or services we offer, or increases in the speed at which we are required to provide products and services, it may strain our systems. Additionally, our systems and networks may become strained due to aging or end-of-life technology that we have not yet updated or replaced.

Our computer operations, as well as our other business centers, and those of our suppliers and clients, may be vulnerable to interruption by fire, natural disaster, public health crisis (e.g., pandemics), extreme weather or climate conditions, power loss, telecommunication failures, terrorist attacks, acts of war or civil unrest, internet failures, computer viruses, security breaches, employee or systems errors, and other events beyond our reasonable control. In addition, in remote work environments, the daily activities and productivity of our workforce are now more closely tied to key vendors consistently delivering their services without material disruption. Our ability to deliver information using the internet and to operate in a remote working environment may be impaired because of infrastructure failures, service outages at third-party internet providers, malicious attacks, or other factors.

We currently use multiple providers of cloud services; however, one supplier provides the majority of our cloud computing support. We have limited control over its performance, and a disruption or loss of service from this provider could impair our system's operation and our ability to operate for a period of time.

We maintain back-up facilities and certain other redundancies for each of our data centers to minimize the risk that any event will disrupt those operations, but if we were to suffer such an event it may mean we are unable to provide our service for a prolonged period of time, and our IT disaster recovery processes may not be adequate. In addition, changes we make to our systems, software, infrastructur

Cybersecurity Risk Management and Strategy

We maintain an information security program with a dedicated internal team that is tasked with leading enterprise-wide cybersecurity strategy, policy, standards, architecture, and processes. Our information security team is responsible for identifying, assessing, managing, and responding to cybersecurity risks, threats and incidents relating to the protection of our information assets, systems and operations. The information security team also oversees the detection, prevention, mitigation and remediation of cybersecurity incidents. Our information security team monitors emerging cyber threat activity to tune and upgrade our cyber capabilities.

Our information security program is managed by a dedicated Chief Information Security Officer ("CISO") who reports to our Chief Technology Officer, a member of our Executive Leadership Team ("ELT"). Our CISO has over 30 years of experience working in technology and cybersecurity at financial services companies, including serving as CISO of a major financial institution. The information security team is comprised of approximately 70 employees, with dedicated teams assigned to governance, risk and compliance, identity and access management, strategy and architecture, product security, and cyber incident detection and response. The team operates from FactSet locations around the world, including offices in the U.S., India, the Philippines and Europe.

FactSet's information security and governance framework is guided by International Organization for Standardization ("ISO") 27001 and System and Organization Control ("SOC") 2 Trust Service Criteria and the National Institute of Standards and Technology ("NIST") Cybersecurity Framework.

Cybersecurity risk management is integrated into our broader Enterprise Risk Management ("ERM") framework. FactSet's ERM program is designed to identify, prioritize and assess the most significant risks that could impact our ability to achieve our strategic business objectives. Our information security leadership team, in concert with our ERM team, reviews our cybersecurity risks each quarter through our enterprise risk assessment process.

FactSet's information security program is grounded in a threat-led risk-based approach. We continuously assess the maturity of our program against evolving threats and leading frameworks, and we identify and prioritize areas for enhancement, which we address through a multi-year cybersecurity strategy. Our information security team undertakes various activities to assess, identify and manage risks from cybersecurity threats, including managing security controls, conducting penetration testing, leading training and tabletop exercises (including an annual tabletop exercise with the ELT), and conducting internal and external vulnerability assessments. All FactSet's employees receive mandatory annual cybersecurity training; software

engineers receive training on secure software development best practices; and other ad hoc training is provided to employees on the latest cyber threat landscape. In addition, we also perform quarterly "phishing simulations" to test the effectiveness of our security training program.

FactSet's information security team performs annual adversarial penetration testing with leading service providers, to mimic motivated threat actors, to assess the internal and external security posture of the Company. Findings from the penetration test and our internal and external vulnerability assessments are classified using a combination of scores and internal business metrics.

We have processes to identify and mitigate cybersecurity risks stemming from our relationships with third parties, including protocols to assess vendors' cybersecurity programs before we engage them and to monitor vendors, once engaged, for ongoing compliance with our cybersecurity standards.

We also have an incident response plan and scenario playbooks that provide procedures for how we can detect, respond to, and recover from potential cybersecurity incidents, which include processes designed to triage, assess severity, escalate, contain, investigate, and remediate any incident, as well as to comply with any applicable legal obligations and mitigate potential brand and reputational damage.

Our information security program is regularly evaluated by internal and external experts with the results of those reviews reported to senior management, including the ELT and the FactSet Audit Committee, and, where appropriate, the Board of Directors (the "Board"). We also actively engage with key vendors, industry participants, and intelligence and law enforcement communities as part of our continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures. These efforts inform our ongoing, multi-year program to mature our cybersecurity posture as the external threat environment evolves.

The cybersecurity threat landscape is dynamic and volatile and requires significant investment. To date, risks from cybersecurity threats have not materially affected, and we do not believe are reasonably likely to materially affect, our business strategy, results of operations, or financial condition. As discussed more fully under Part I, Item 1A, Risk Factors in this Annual Report on Form 10-K, although our processes are designed to help identify, detect, prevent, respond to, and mitigate cybersecurity risks, cybersecurity threats are rapidly evolving and we may not be able to anticipate, prevent, or detect all such attacks and there is no guarantee that a future cybersecurity incident could not materially affect our business strategy, results of operations, or financial condition.

Cybersecurity Governance

Cybersecurity is an important part of the risk management focus of our Audit Committee, Board and ELT. The Audit Committee has primary oversight of our technology and cyber risk profile, cyber strategies and information security initiatives. The Audit Committee monitors management’s responsibility in the area of risk oversight, including cybersecurity risks. At each regular meeting, the Audit Committee receives updates from the CISO regarding trends, emergent risks to our technology infrastructure, major updates on security assessments and threat landscape, and the steps we are taking to respond to these matters. The full Board is kept informed through regular updates from the Audit Committee Chair and an annual update from the CISO, or as may otherwise be required.

Management has day-to-day responsibility for identifying risks facing FactSet, formulating risk management policies and procedures, managing our key risk exposures on a day-to-day basis and setting the right “tone at the top.” As part of this, the ERM and technology teams, including the CISO, also deliver regular updates to the ELT on cybersecurity and related matters.

As of August 31, 2026, we have 33 offices worldwide, including our corporate headquarters located at 45 Glover Avenue, Norwalk, Connecticut where we occupy 91,718 square feet of office space. These offices include our data content collection offices located in India and the Philippines. We also have two data centers that support our technological infrastructure located in the U.S.

Refer to the table set forth below for the listing of our leased office space by geographic location. We believe our existing and planned leased space is suitable and adequate for our current business needs. We regularly review our real estate footprint to best support our operations and should our real estate needs increase, we believe additional space will be available.

Market Information

Our common stock is listed on the NYSE and Nasdaq under the symbol "FDS".

Holders of Record – As of October 15, 2026, we had approximately 1,757 holders of record of our common stock. However, because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

Dividends - We paid four quarterly dividends during fiscal 2026. In the third quarter of fiscal 2026, we increased our quarterly cash dividend from $1.10 to $1.16 per share. Future cash dividend payments are subject to final determination by our Board of Directors and will depend on our earnings, capital requirements, financial condition and other relevant factors. Refer to Part II, Item 8. Note 12, Stockholders' Equity, in the Notes to the Consolidated Financial Statements of this Annual Report on Form 10-K for more information on our dividends.

Fiscal 2026 in Review

Revenues totaled $2,476.3 million for fiscal 2026, an increase of 6.7% compared to the prior year, driven by a corresponding 6.7% increase in organic revenues. Revenues increased in all our segments, mainly in the Americas. Revenues increased primarily from workstations, data solutions and, to a lesser extent, portfolio management and trading solutions. Refer to Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, Non-GAAP Financial Measures, of this Annual Report on Form 10-K for a definition of organic revenues and a reconciliation between revenues and organic revenues.

As of August 31, 2026, organic annual subscription value ("Organic ASV") totaled $2,568.2 million, an increase of 7.0% over the prior year. Organic ASV increased in all our segments, with the majority of the increase in the Americas. Organic ASV growth was mainly driven by data solutions and, to a lesser extent, workstations and middle office solutions. Refer to Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, Annual Subscription Value, of this Annual Report on Form 10-K for the definition of Organic ASV.

Operating margin was 28.3% for fiscal 2026, compared with 32.2% for fiscal 2025. This decrease was primarily driven by higher operating expenses as a percentage of revenues, mainly due to an increase in employee compensation costs, primarily driven by restructuring charges, higher variable compensation costs and one-time CEO compensation costs pursuant to the terms of his employment agreement, partially offset by growth in revenues.

Net income for fiscal 2026 was $533.5 million, a decrease of 10.6% from the prior year. Diluted earnings per common share ("Diluted EPS") for fiscal 2026 was $14.57, a decrease of 6.3% compared with the prior year. These decreases were primarily driven by higher operating expenses, including non-recurring items, partially offset by growth in revenues. The decrease in Diluted EPS was also partially offset by a reduction in the diluted weighted average common shares outstanding of approximately 1.8 million shares.

We returned $808.1 million to our stockholders in the form of share repurchases and dividends during fiscal 2026.

As of August 31, 2026, our client and user counts were 9,258 and 260,671, respectively. Our employee headcount was 12,444 as of August 31, 2026, a decrease of 2.8% compared to the prior year, primarily due to restructuring and reduced hiring, reflecting net headcount reductions of 5.5% in the Americas, 2.3% in Asia Pacific and 1.2% in EMEA.

Annual Subscription Value ("ASV")

We believe ASV reflects our ability to grow recurring revenues and generate positive cash flows, and thus serves as a key indicator of the successful execution of our business strategy.

–ASV at any point in time represents our forward-looking revenues for the next 12 months from all recurring services currently being supplied to clients.

–Organic ASV at any point in time equals our ASV excluding ASV from acquisitions and the comparable impact of disp

In the normal course of business, we are exposed to foreign currency exchange risk and interest rate risk that could impact our financial position and results of operations. Current market events have not required us to materially modify our financial risk management strategies with respect to our exposures to foreign currency exchange risk or interest rate risk.

Foreign Currency

Transaction Risk

As we operate globally, we are exposed to the risk that our financial condition, results of operations and cash flows could be impacted by changes in foreign currency exchange rates. During fiscal 2026, we maintained a series of foreign currency forward contracts to hedge a portion of our projected operating expenses in these primary currency exposures, namely the British Pound Sterling, Euro, Indian Rupee and Philippine Peso. As of August 31, 2026, the hedge maturity periods of our outstanding foreign currency forward contracts range from the first quarter of fiscal 2027 through the fourth quarter of fiscal 2027. Based on the operating income for fiscal 2026, comparing the average foreign currency exchange rates for fiscal 2026 to the respective rates for fiscal 2025 and the impact of the change in hedge activity, resulted in a decrease in operating income of $2.1 million. We utilize cash flow hedges to manage risk and not for speculative or trading purposes.

We performed a sensitivity analysis to determine the effects on both the fair value of our outstanding foreign currency forward contracts and our operating income, excluding these forward contracts, of a hypothetical devaluation of the U.S. dollar by 10% as of August 31, 2026, relative to the other foreign currencies in which we transact. The sensitivity analysis indicated that a devaluation of the U.S. dollar by 10% would have increased the fair value of our outstanding forward contracts by approximately $19 million as of August 31, 2026 and decreased our operating income, excluding these forward contracts, by an estimated $51 million for fiscal 2026. This sensitivity analysis has inherent limitations as it disregards the possibility that rates of multiple foreign currencies will not always move in the same direction relative to the value of the U.S. dollar over time and does not account for our forward contracts that we utilize to mitigate fluctuations in exchange rates.

Translation Risk

We are exposed to foreign currency risk due to the translation of our results from certain international operations into U.S. Dollars, as part of the consolidation process. Fluctuations in foreign currency exchange rates can create volatility in our results of operations and our financial condition.

The following table reflects the foreign currency translation adjustment gains and losses recorded in Other comprehensive income (loss):

Cash and Cash Equivalents and Investments

Interest Rate Risk

As of August 31, 2026, we had Cash and cash equivalents of $233.3 million and Investments of $32.0 million. Our cash equivalents primarily consist of money market funds and our Investments consist of mutual funds. We are exposed to interest rate risk through fluctuations in interest rates on our money market funds and mutual funds. As we have a restrictive investment policy, our financial exposure to fluctuations in interest rates is expected to remain low. Refer to Part II, Item 8. Note 2, Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K for more information on our Cash and cash equivalents.

Credit Risk

We are exposed to credit risk for our cash, cash equivalents and restricted cash held in financial institutions in the event of a default, to the extent that such amounts are in excess of applicable insurance limits; however, we do not believe our concentration of cash, cash equivalents and restricted cash presents a significant credit risk as the counterparties to the instruments consist of multiple high-quality, credit-worthy financial institutions.

Debt

Interest Rate Risk

Our Senior Notes have a fixed interest rate and are not subject to interest rate change. As such, our interest rate exposure is limited to the outstanding balance of our floating rate debt under our 2025 Credit Facilities. As of August 31, 2026, this outstanding balance was $375.0 million, which bore interest at a rate equal to the applicable one-month Term SOFR plus a 0.875% interest rate margin, based on a debt leverage pricing grid. Assuming the principal balance of our outstanding floating rate debt remained at $375.0 million, a hypothetical 25 basis point change (up or down) in the one-month SOFR would result in an approximate $1 million change to our annual interest expense.

Refer to Part II, Item 8. Note 10, Debt in the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K for more information on our outstanding borrowings.

Management’s Statement of Responsibility for Financial Statements

Our management prepares and is responsible for the fairness, integrity and objectivity of our Consolidated Financial Statements. The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and include amounts based on our management’s estimates and judgments. All financial information in this Report on Form 10-K has been presented on a basis consistent with the information included in the accompanying financial statements.

Our policies and practices reflect corporate governance initiatives that are compliant with the listing requirements of the New York Stock Exchange, the Nasdaq Stock Market and the corporate governance requirements of the Sarbanes-Oxley Act of 2002. Our management, with oversight by our Board of Directors, has established and maintains a strong ethical climate so that our affairs are conducted to the highest standards of personal and corporate conduct.

We maintain accounting systems, including internal accounting controls, designed to provide reasonable assurance of the reliability of financial records and the protection of assets. The concept of reasonable assurance is based on recognition that the cost of a system should not exceed the related benefits. The effectiveness of those systems depends primarily upon the careful selection of financial and other managers, clear delegation of authority and assignment of accountability, inculcation of high business ethics and conflict-of-interest standards, policies and procedures for coordinating the management of corporate resources, and the leadership and commitment of top management. In compliance with the Sarbanes-Oxley Act of 2002, we assessed our internal control over financial reporting as of August 31, 2026 and issued a report (see below).

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for FactSet. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Our management (including our Principal Executive Officer and Principal Financial Officer) conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of August 31, 2026. Ernst & Young LLP (PCAOBID: 42), an independent registered public accounting firm, has audited the effectiveness of our internal control over financial reporting and has issued a report on our internal control over financial reporting, which is included in their report on the subsequent page.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of FactSet Research Systems Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of FactSet Research Systems Inc. (the Company) as of August 31, 2026 and 2025, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the period ended August 31, 2026, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at August 31, 2026 and 2025, and the results of its operations and its cash flows for each of the three years in the period ended August 31, 2026, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of August 31, 2026 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated Oct

Evaluation of Disclosure Controls and Procedures

Our management, including our Principal Executive Officer and Principal Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") as of the end of the annual period covered by this report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that, as of August 31, 2026, our disclosure controls and procedures were effective.

Remediation of Previously Reported Material Weakness

As first reported in our Annual Report on Form 10-K for the fiscal year ended August 31, 2024, we identified deficiencies in the design and operation of IT general controls that support our revenues, accounts receivable, and deferred revenues processes which, in the aggregate, gave rise to a material weakness in internal control over financial reporting. Management, with the oversight of the Audit Committee of our Board of Directors, executed a remediation plan, which included:

• Implementing controls that increase the frequency and effectiveness of user access management and change management, including improved logging and segregation of duties capabilities.

• Formalizing standard operating procedures and documentation for change monitoring and segregation of duties review controls and training relevant personnel on the design and operation of our IT general controls.

• Performing additional testing of IT general controls to demonstrate the sustainability and repeatability of control operating effectiveness.

• Implementing technology solutions to enhance the control framework for supporting change monitoring, segregation of duties and access management review controls.

• Hiring additional IT compliance personnel and Chief Audit Executive.

During the year ended August 31, 2026, management completed our testing of these remediation measures. The enhanced controls operated for a sufficient period of time, and management completed testing of their design and operating effectiveness in the fourth quarter. Based on the results of this testing, management concluded that the material weakness was remediated as of August 31, 2026.

Changes in Internal Control over Financial Reporting

Other than completion of the remediation measures described above, there were no changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of fiscal 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
