ALLIANCEBERNSTEIN L.P. 8-K

What Happened
AllianceBernstein L.P. filed an 8-K and issued a press release on January 5, 2026 announcing the appointment of Onur Erzan, age 50, as President, effective immediately. Mr. Erzan was promoted from his role as Head of Global Client Group and Private Wealth (since 2022) and recently took on oversight of Global Private Alternatives in Fall 2025. He assumes the President role from Seth Bernstein, who will continue as Chief Executive Officer.

Key Details

• Appointment effective January 5, 2026; disclosed in an 8-K and company press release.
• Onur Erzan has been with AllianceBernstein since 2021 and led Global Client Group & Private Wealth since 2022.
• Prior to AB, Mr. Erzan spent ~20 years at McKinsey & Company, most recently as a Senior Partner and co-leader of Wealth & Asset Management.
• Mr. Erzan will chair the AB Operating Committee and remains a member of the Equitable Holdings Management Committee; Seth Bernstein continues as CEO.

Why It Matters
This is a senior leadership change that clarifies AllianceBernstein’s executive structure without replacing the CEO. For investors, the move signals continuity at the CEO level while elevating an experienced client- and wealth-focused executive to lead day-to-day operations and the operating committee. The filing is procedural (an 8-K) and does not include financial results, but leadership changes can affect strategy execution, client relationships and operating oversight.
