About
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.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
