Summary

Summary of the 8-K filed June 6, 2025. Cited figures are marked; the original filing is the authoritative source.

Affiliated Managers Group (AMG) filed an 8-K on June 6, 2025 disclosing that Thomas M.

Wojcik was appointed President of the Company effective June 3, 2025, while retaining his role as Chief Operating Officer. Jay C. Horgen, who had been President and CEO, will continue as Chief Executive Officer, so the change expands Wojcik's responsibilities rather than replacing Horgen.

The filing describes Wojcik as a co-developer of AMG's growth strategy, and he will continue to report to Horgen. Wojcik joined AMG in 2019 from BlackRock and served as CFO from 2019 through 2024 before becoming COO in 2024. The Compensation Committee approved a one-time restricted stock unit award under the 2020 Equity Incentive Plan with a grant-date fair value of $5.0 milliona.

The award vests in March 2030 and is fully subject to performance-based conditions, which is intended to tie his compensation to long-term value creation. Details required under Regulation S-K Items 401 and 404 are incorporated by reference from AMG's April 11, 2025 proxy statement, so the 8-K itself adds limited new governance detail. The press release also highlights strategic positioning.

Management said private markets and liquid alternative strategies now contribute half of AMG's earnings, and aggregate AUM was approximately $712 billionb as of March 31, 2025. For investors, the key takeaways are a succession-oriented leadership expansion with clear CEO continuity and a long-dated, performance-contingent incentive, rather than any change to financial results or guidance.
