Atlantic Investment Management

What Atlantic Investment Management does

Atlantic Investment Management is a privately held, catalyst-driven value-oriented equity investment firm founded in 1988 by Alexander J. Roepers and headquartered at 1301 Avenue of the Americas, New York. The firm invests primarily in undervalued mid-cap industrial and consumer products and services companies across the United States, Europe, and Japan, combining concentrated capital allocation, hands-on fundamental research, and a constructive shareholder activism (CSA) approach to engage management and boards on capital allocation and operational improvement. Its flagship product, the Cambrian Fund (US-focused), has generated a 33+ year record of net returns substantially in excess of equity market indexes since 1992, complemented by three additional vehicles — Cambrian Global, Cambrian Europe, and Cambrian Japan — that apply the same methodology across geographies and themes such as Japan's corporate reform cycle.

The firm operates a conventional investment management revenue model consisting of recurring management fees on assets under management plus performance-based fees aligned with client returns, distributed via direct institutional sales to pensions, endowments, foundations, and family offices. Atlantic has been a Registered Investment Adviser since 2006 and reports its long equity positions through quarterly 13F filings, which have shown active 13F portfolio rotation during 2025-2026 (initiating positions in Kirby Corporation, Dauch Corporation, and Axalta Coating Systems; exiting Graphic Packaging and trimming Oshkosh). Current AUM is reported at approximately $1.3 billion versus a historical peak of $5 billion, with the gap reflecting industry-wide value strategy outflows rather than deterioration of the firm's investment process. Marketing and capital raising rely on thought leadership via founder-led media appearances in Institutional Investor, Wall Street Journal, Barron's, Bloomberg, CNBC, and value investing conferences, supplemented by quarterly Zoom updates.
