FACTSET RESEARCH SYSTEMS INC

The general policy of the Board is that compensation for directors should be a mix of cash and equity-based compensation. We do not pay management directors for Board service in addition to their regular employee compensation. The Compensation and Talent Committee, which consists solely of independent directors, has the primary responsibility for reviewing and considering any revisions to director compensation. The Board reviews the committee’s recommendations and determines the amount of director compensation. Each director is provided access to FactSet services, at no charge, which allows them to utilize our suite of products.

Compensation for the Board is set on a calendar year basis. During fiscal 2025, non-employee director compensation consisted of:

For the period September 1, 2024 through December 31, 2024:

•An annual retainer of $60,000. Each director could choose to receive the retainer as a quarterly cash payment or receive the equivalent value in an equity grant consisting 50% of non-qualified stock options and 50% of restricted stock units;

•An equity grant of non-qualified stock options having an intended grant date fair value of $75,000; and

•An equity grant of restricted stock units having an intended grant date fair value of $75,000.

The Compensation and Talent Committee, with advice and information from the independent compensation consultant, periodically reviews the competitiveness of the Company's non-employee director compensation based on pay practices among the Company's peer group, as described starting on page 35, and broader general industry practices. For calendar year 2025, we

2025 Proxy Statement 17 updated our non-employee director compensation program, based on the Committee's review of competitive market analysis and advice of Meridian Compensation Partners, in order to deliver more market competitive total pay.

Accordingly, for the period January 1, 2025 through August 31, 2025:

•An annual retainer of $60,000. Each director may choose to receive the retainer as a quarterly cash payment or receive the equivalent value in an equity grant consisting 37.5% of non-qualified stock options and 62.5% of restricted stock units;

•Annual retainers of $50,000 for the Board Chair, $25,000 for the Chair of the Audit Committee, $25,000 for the Chair of the Compensation and Talent Committee, and $15,000 for the Chair of the Nominating and Corporate Governance Committee, all of which the director may choose to receive in cash or equity, as described above;

•An equity grant of non-qualified stock options having an intended grant date fair value of $75,000; and

•An equity grant of restricted stock units having an intended grant date fair value of $125,000.

Equity grants for non-employee directors are made on January 15 (or the first business day thereafter) of each year. Stock options granted to non-employee directors vest fully on the first anniversary of the grant date and have a seven-year term. Restricted stock units granted to non-employee directors vest fully on the first anniversary of the grant date.

•Any director appointed during a calendar year is entitled to receive:

•Pro rata cash payments of the annual retainer during the year the director begins service; and

•A pro rata equity grant for the appropriate portion of the first year of service on January 15 (or the first business day thereafter) of the year following the start of service, in addition to the standard annual grant for the year following the start of service.

The FactSet Research Systems Inc. Non-Employee Directors’ Stock Option and Award Plan, as Amended and Restated (the “Director Plan”) provides for the grant of stock-based awards, including stock options and restricted stock units, to non-employee directors of FactSet. Under the Director Plan, the Compensation and Talent Committee may award an annual equity grant to each non-employee director on or around January 15th of each year. The number of option shares or restricted stock units to be granted in order to deliver the intended value will be determined on the grant date.

The Compensation and Talent Committee recommended and the Board approved an annual equity grant of 518 non-qualified stock options and 278 restricted stock units to each of the non-employee directors serving on the Board on January 15, 2025. Additionally, each non-employee director serving on the Board on January 15, 2025 was given an award of $60,000 with the election to receive the retainer as a quarterly cash payment or receive the equivalent value in a mix of non-qualified stock options and restricted stock units. For calendar year 2025, directors Abrams, Frank, Shavel, and Tejada opted for the equity grant consisting of 155 non-qualified stock options and 83 restricted stock units. Directors Abrams, Hylton, Siegel, and McGonigle each received additional retainers for their service as Chair.

The exercise price for the non-qualified stock options granted under the retainer and annual grant was $453.98 per share, being equal to the closing price of FactSet common stock on January 15, 2025. The grant date fair value for all non-qualified stock options was $144.90 and the grant date value for all restricted stock units was $449.72. The non-qualified stock options granted to directors vest 100% on the first anniversary of the date of grant and expire seven years from the date of grant while the restricted stock units granted to directors vest 100% on the first anniversary of the date of grant.

On September 22, 2020, the Board adopted stock ownership guidelines that require each of our non-employee directors to own FactSet stock having a value of at least $400,000. See "Compensation Discussion and Analysis — Stock Ownership Guidelines."

We pay or reimburse our directors for travel, lodging and related expenses incurred in connection with attending Board, committee and stockholder meetings and other Company business related events. From time to time, we may reimburse a director’s

2025 Proxy Statement 18 expenses for participation in third party-supplied continuing education related to the director’s Board or committee service. There was no reimbursement for educational participation made to the directors during fiscal 2025.
