Overview

First Manhattan Co LLC is a long-established, SEC-registered investment adviser that serves both individual/family and institutional clients. The firm provides comprehensive advisory services that span financial planning, portfolio management for individuals, pooled vehicles and institutional clients, and pension consulting. It operates as an LLC, charges fees based on a percentage of assets under management and, in some cases, performance-linked fees, and maintains affiliations consistent with broker‑dealer and trust activities as well as sponsoring and acting as GP/managing member of pooled investment vehicles. The firm’s investment approach is equity-centric and not positioned as an active ESG investor. Its client mix and product menu allow it to work across separately managed accounts, pooled funds and vehicles it sponsors or manages, which aligns with the range of advisory activities listed on its filings. First Manhattan also received recognition in Barron’s 2025 list of Top 100 RIA Firms.
