AllianceBernstein L.P. Announces CEO Retirement, Names New CEO

What Happened

• AllianceBernstein L.P. (ABLP) filed an 8-K on Sept. 25, 2026 announcing that current CEO Seth Bernstein will retire effective March 31, 2027 and will remain on the firm’s board after retirement. The firm named Onur Erzan (age 50), currently President, as President and Chief Executive Officer effective April 1, 2027; he will also join the AB Board on that date. A press release was issued the same day under Regulation FD.

Key Details

• Seth Bernstein retirement package: restricted AB Holding Unit awards with a total grant date fair value of $2.5M (three-year annual vesting to be issued around the Retirement Date); a $1.0M Equitable Holdings LTIP award to be issued in Q2 2027; 26 weeks of salary continuation totaling $325,000; continued benefits and transition support, subject to customary restrictive covenants and assistance obligations.
• Onur Erzan compensation (offer letter): base salary $650,000 (effective Jan. 1, 2027); 2027 total compensation target of $13.5M composed of cash bonus $5.8M, AB ICAP award $3.45M, Equitable Holdings equity $2.35M, and the annual amortized value of a prior 2025 restricted AB award $1.25M.
• Severance and post-termination terms for Erzan: if terminated without Cause (or resigns for Good Reason), eligible for 1.5x annual base salary plus annual bonus, COBRA cost payments for 18 months (after-tax), prior-year earned bonus when paid to peers, and continued vesting of unvested equity awards; subject to a 6-month non-compete and 12-month non-solicitation as a condition of severance.

Why It Matters

• Leadership transition is material for investors because it establishes AB’s CEO succession timeline and commits near-term compensation and severance obligations that affect executive expense and governance. The filing details specific compensation arrangements and restrictive covenants, and confirms continuity (Bernstein remains on the board) while Onur Erzan — with prior roles at AB and a long consulting background — takes operational control starting April 1, 2027.
