AllianceBernstein Promotes Onur Erzan to President
AllianceBernstein Holdings, an investment management subsidiary of Equitable Holdings, has promoted Onur Erzan, head of private wealth, to president of the Nashville, Tenn.-based business unit.
Erzan will take the role from CEO Seth Bernstein, who will remain in the top job while working with Erzan to “oversee the transformation of AB’s business prioritization and strategic initiatives,” according to an announcement Monday.
As president, Erzan will lead strategy and corporate development, while continuing his job heading AB’s private wealth management, global asset management distribution and global private alternatives businesses.
Ezran has been part of leading AB’s distribution strategy and expanding into new areas such as active exchange-traded funds, insurance asset-management products, and retirement income, according to the announcement. He has also grown AB’s private wealth team and resources, including partnerships with banks and international custodians.
The new president was promoted to his former role in fall 2025 after joining AB in 2021 after a 20-year career at consultancy McKinsey & Company. He will now also serve as chair of AB’s operating committee, while remaining on Equitable’s management committee.
ETF Provider Tidal Financial Makes Leadership Change
Tidal Investments, a part of white-label ETF provider Tidal Financial Group, has elevated Chief Revenue Officer Gavin Filmore to CEO, while co-founder and former CEO Guillermo Trias moves to the role of executive chairman.
Filmore will take on the day-to-day management and operations of New York-based Tidal after joining the firm in 2021 from Barclays Capital, where he was head of ETF products. He had been the head of product development, then chief operating officer and finally chief revenue officer as of January 2024, according to his LinkedIn profile.
Co-founder Trias, meanwhile, will transition to a role of strategic oversight, planning and supporting corporate initiatives, according to an announcement.
“In a rapidly evolving marketplace where investors are seeking increasingly sophisticated products, Gavin is the ideal leader to guide Tidal’s next chapter,” Trias said in a statement.
As of Jan. 1, 2026, Tidal supports over 360 funds and manages assets totaling more than $45 billion, with an additional $17 billion in assets under service. It works with about 90 asset managers.
NEPC Retirement Lead Bill Ryan Moves to Carlyle Group
Bill Ryan, a former partner and defined contribution leader at Hightower’s institutional consulting firm NEPC, moved in December to a role leading retirement solutions at global investment firm The Carlyle Group, according to a post on LinkedIn.
Ryan made the move a little over a year after Hightower announced it was acquiring the institutional consulting firm and an outsourced chief investment officer that had been overseeing about $1.8 trillion in assets under advisement. He had been with NEPC for over four years, having joined the firm from Aon.
Ryan is a frequent commentator on defined contribution and retirement issues, has held positions with the Defined Contribution Institutional Investment Association, and is currently a member of the ERISA Advisory Council.
“With great gratitude, I am excited to begin my next chapter in 2026, helping U.S. workers prepare to retire with dignity by leading retirement solutions at The Carlyle Group,” Ryan wrote in a post.
Hiring Ryan is a further indication of Carlyle positioning its offerings across institutional and retail investors in partnership with advisors. In August of 2025, it acquired Invesco’s financial advice and investment management provider intelliflo, which included its U.S.-based subsidiaries RedBlack, a provider of SaaS-based portfolio rebalancing tools, and intelliflo Portfolio, a management software tool for U.S.-based RIAs.
