AllianceBernstein Holding L.P. is a publicly traded master limited partnership that primarily holds an ownership interest in AllianceBernstein L.P., the operating investment manager (together referred to as AB). AB provides global investment management and related services across three distribution channels: Institutions, Retail, and Private Wealth Management. The firm earns most of its revenue from investment advisory and services fees that are typically calculated as a percentage of assets under management (AUM), making results sensitive to market levels and net flows. AB’s parent, Equitable Holdings (EQH), is both the controlling owner and AB’s largest client, and the relationship is used to seed and scale higher-fee private/illiquid alternative capabilities.
