AllianceBernstein Holding L.P. (NYSE:AB), known as AB Holding, has publicly traded units listed on the New York Stock Exchange. On 12 October 2026, at 4:05 pm Eastern time, AllianceBernstein L.P. and AB Holding announced preliminary assets under management (AUM) for 30 September 2026. Total AUM was US$900 billion, down US$19 billion, or about 2%, from US$919 billion at 31 August 2026. The release attributed the fall primarily to market depreciation, coupled with net outflows during the month.

What the units represent

AB Holding units are not shares in the operating business directly. AB Holding is a publicly traded partnership whose main asset is its interest in AllianceBernstein L.P., the operating partnership that manages client money. In its second-quarter release, the company said AB Holding owned approximately 31.3% of AllianceBernstein at 30 June 2026. AB Holding must distribute its Available Cash Flow, typically calculated as adjusted net income per unit multiplied by the number of units, so the quarterly distribution tracks the operating partnership's adjusted earnings.

September AUM in detail

All figures are preliminary and in US dollars. Equity AUM was US$356 billion, compared with US$364 billion at the end of August, while fixed income fell to US$315 billion from US$323 billion. Alternatives and multi-asset solutions slipped to US$229 billion from US$232 billion. Actively managed equity declined from US$273 billion to US$266 billion. Passive equity edged down from US$91 billion to US$90 billion, and passive fixed income from US$18 billion to US$17 billion. Every asset class in the release's table declined.

By channel, Institutional recorded net inflows for the month, partly offset by net outflows in Retail and Private Wealth. The company also reported preliminary firmwide net inflows of about US$6.0 billion for the quarter ended 30 September 2026.

Second-quarter results for context

On 28 July 2026 the company reported results for the quarter ended 30 June 2026. GAAP net income per unit was US$0.77, up 20.3% from US$0.64 a year earlier. Adjusted net income per unit was US$0.82, up 7.9% from US$0.76, and the cash distribution per unit was also US$0.82, payable on 27 August 2026 to holders of record on 12 August 2026.

At the operating partnership, GAAP net revenues were US$1,171.0 million, up 7.5% year on year, and adjusted net revenues were US$887.5 million, up 5.1%. Adjusted operating income was US$293.0 million with an adjusted operating margin of 33.0%, 70 basis points higher than a year before. Ending AUM then was a record US$905.5 billion. Net inflows were US$0.8 billion, with passive strategies adding US$9.4 billion and active strategies losing US$8.6 billion.

Chief executive Seth Bernstein said the firm returned to organic growth in the second quarter.

Why it matters

Fee income at asset managers depends heavily on the level of AUM, so a two per cent monthly decline can feed through to revenues, although mix and performance fees also matter. The shift towards passive strategies and away from active equity is a recurring pressure point, because active mandates generally carry higher fees. The company has not disclosed fee rates in these releases.
