AllianceBernstein Names Onur Erzan President

AllianceBernstein L.P. announced Monday that Onur Erzan was appointed its president, effective immediately, splitting off a role that was previously held by CEO Seth Bernstein since 2017.

As president, Erzan will partner with Bernstein, who remains CEO, and assume responsibility for AB’s strategy and corporate development functions. Erzan will also continue to lead AB’s private wealth management, global asset management distribution and global private alternatives businesses, which he assumed in fall 2025, according to the announcement.

The announcement also said that Ezran will remain a member of the Equitable Holdings management committee and serve as chair of AB’s operating committee.

“This is a pivotal moment for AB,” Bernstein said in an statement. “Onur’s appointment to president underscores his criticality to AB and Equitable Holdings, and his strong connections both within the firm and across the industry. Onur has built a robust and effective distribution business through his commitment to our clients. He has a passion for winning and a strong belief in identifying key success factors for our business and future success.”

In asset management, Erzan played a “pivotal role” in launching AB’s exchange-traded funds business and insurance asset-management vertical and enhancing retirement income solutions, according to the announcement.

“Since joining AB, I’ve been inspired by our colleagues in offices around the world, our firm’s commitment to innovation, and our collective passion to ensure client success,” Erzan said in a statement. “I’m honored to step into the role of president and look forward to charting the firm’s future alongside Seth.”

Prior to joining AB in January 2021, Ezran spent 20 years with McKinsey & Company, most recently as a senior partner and co-leader of its wealth and asset management practice.

AB’s Lifetime Income Strategy received a regulatory boost last September, when the U.S. Department of Labor issued an advisory opinion affirming that AB’s product met the criteria to be classified as a qualified default investment alternative under the Employee Retirement Income Security Act—a move that could spur broader adoption by plan sponsors.

As of November 30, 2025, AllianceBernstein had $865 billion in assets under management.
