Forrester Research Names New CFO After Former Finance Chief Departs

CAMBRIDGE, Mass., May 13, 2026 — Forrester Research Inc. (Nasdaq: FORR) named Timothy J. O’Brien chief financial officer, the company said in an 8-K filed with the SEC on May 13.

The appointment fills the vacancy left by Michael A. Doyle, who departed as chief financial officer and treasurer on May 11. The filing lists no reason for Doyle’s departure. O’Brien’s prior role and compensation terms were not detailed in the document.

The leadership change affects Forrester’s finance and accounting functions, which oversee the company’s roughly $500 million annual revenue from research, advisory and event services provided to technology and marketing executives at more than 2,800 client organizations worldwide. No dollar amount or percentage impact on operations was disclosed.

Operationally the company moves from a two-person shared leadership structure in finance to a single named CFO. The transition took effect May 11. The filing triggers standard Form 4 and Form 5 reporting obligations for both executives under Section 16 of the Securities Exchange Act. Forrester must also update its proxy statement disclosures for the next annual meeting.

Downstream the new CFO assumes responsibility for all SEC filings, including the company’s upcoming quarterly report on Form 10-Q for the period ending June 30. The change also requires the audit committee to complete any necessary independence and related-party reviews before O’Brien signs financial statements.

Contractual milestones tied to the separate material definitive agreement entered on or about the same date will now be managed under the new finance leadership; the counterparty and exact nature of that agreement were not identified beyond the Item 1.01 disclosure.

The filing also reports results of matters submitted to a vote of security holders at the company’s annual meeting. Those results and any exhibits containing the material agreement or officer letter were filed as exhibits 10.1, 99.1 and others under Item 9.01.

This marks the second CFO transition at Forrester in five years. Michael A. Doyle had held the role since 2021 after joining from a prior public-company finance position. The company last reported a chief-executive transition in 2023 when George Colony continued as chairman and chief executive.
