FACTSET RESEARCH SYSTEMS INC

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 GAAP. 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 (with the participation of the Chief Executive Officer and Chief 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 not effective as of August 31, 2024 as a result of the material weakness in internal control over financial reporting described below.

Our management has identified certain control deficiencies related to the design and operation of our information technology (“IT”) general controls (“ITGCs”) that support our revenues, accounts receivable, and deferred revenues processes which, in the aggregate, rise to a material weakness in internal control over financial reporting. The deficiencies related to program change management and user access in connection with segregation of duties and restriction to appropriate users. As a result, the automated controls and IT dependent manual business process controls that rely upon information from the affected financial applications were also deemed not effective. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

While we have concluded that these control deficiencies did not result in any material misstatements in our Consolidated Financial Statements or disclosures in any of the fiscal years ended August 31, 2024, 2023 or 2022, they were not remediated as of August 31, 2024, and thus created a reasonable possibility that they could result in a material misstatement to the Consolidated Financial Statements that would not be prevented or detected on a timely basis. Accordingly, we determined that these control deficiencies constituted a material weakness.

After giving full consideration to the material weakness, and the additional analyses and other procedures we performed to ensure that our Consolidated Financial Statements included in this Annual Report on Form 10-K were prepared in accordance with GAAP, our management has concluded that our Consolidated Financial Statements present fairly, in all material respects, our financial position, results of operations and cash flows for the periods disclosed in conformity with GAAP.

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 an adverse opinion on the effectiveness of our internal control over financial reporting as stated in their report on the subsequent page.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of FactSet Research Systems Inc. (the Company) as of August 31, 2024 and 2023, 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, 2024, 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, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended August 31, 2024, 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, 2024, 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 October 29, 2024 expressed an adverse opinion thereon.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Opinion on Internal Control Over Financial Reporting

We have audited FactSet Research Systems Inc.’s internal control over financial reporting as of August 31, 2024, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria, FactSet Research Systems Inc. (the Company) has not maintained effective internal control over financial reporting as of August 31, 2024, based on the COSO criteria.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment. Management has identified a material weakness related to the design and operation of information technology (“IT”) general controls for certain financial applications that support the revenue, accounts receivable, and deferred revenue processes. Consequently, automated controls and IT dependent manual business process controls that rely upon information from the affected financial applications were also deemed ineffective.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of August 31, 2024 and 2023, 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, 2024, and the related notes and financial statement schedule listed in the Index at Item 15(a). This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2024 and 2023 consolidated financial statements, and this report does not affect our report dated October 29, 2024, which expressed an unqualified opinion thereon.

Basis for Opinion

Definition and Limitations of Internal Control Over Financial Reporting

A company’s 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. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 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.
