San Francisco, CA Office

First Manhattan Co. LLC provides discretionary and non‑discretionary investment management and financial planning primarily for high‑net‑worth individuals, along with trusts, pension and profit‑sharing plans, charitable organizations, private investment vehicles and institutional clients. As of year‑end 2025 the firm reported managing roughly $38 billion through a team of about 65 portfolio professionals.

The firm emphasizes long‑term, research‑driven, value‑oriented management of equity and fixed‑income portfolios, with portfolio managers devoting substantial time to fundamental research that can include face‑to‑face meetings with company management and industry contacts. Advice is tailored to client objectives and delivered via individually managed portfolios that may combine actively managed holdings and third‑party passive fund investments, and the firm typically integrates wealth planning alongside portfolio management.

Distinctive features include an assets‑per‑advisor level above $200 million, a higher AUM‑per‑advisor ratio than many enterprise peers, and active management of investment companies — including several private funds (with strategies focused on the banking sector and companies with significant China revenue) and two non‑transparent exchange‑traded funds. The firm is affiliated with an in‑house, state‑chartered trust company that offers trustee and estate administration services and operates alongside an affiliated broker‑dealer and acquired adviser practices; the brochure discloses the governance and compensation conflicts those arrangements can create and describes policies and oversight intended to address them.
