What Engine Capital does
Engine Capital Management, LP is a New York-based activist hedge fund founded in March 2013 by Arnaud Ajdler that operates as a value-oriented special situations investment vehicle. The firm invests both actively and passively in publicly traded companies undergoing change, applying a fundamental, primary-research-driven methodology to identify mispriced equities and engaging constructively with management teams and boards of directors to unlock shareholder value. Its investment philosophy emphasizes strict valuation discipline, concentrated best-idea positioning, long-term orientation, and limiting permanent capital loss through rigorous due diligence. The legal entity operates as a Delaware/New York limited partnership under the name Engine Capital Management, LP, governed by New York law.
The firm's revenue model follows standard hedge fund economics: management fees on assets under management plus performance fees on realized gains, with capital sourced from institutional investors through direct fundraising. Engine deploys capital through concentrated minority activist positions in publicly traded companies, with disclosed stakes including UniFirst (~3.2%, leading to the announced $5.5B sale to Cintas), Upwork (~3.5%), Orthofix Medical (>10% built across February-May 2026), Civeo Corporation, Fox Factory Holding, KBR (reduced from 6.1% of AUM in Q4 2025), and Weave Communications. The firm operates with 11-50 employees from its headquarters at 1345 Avenue of the Americas, 33rd Floor, New York, NY 10105, and markets itself through its website, press releases, investor relations outreach, presentations at industry conferences including Sohn, and select media appearances (Yahoo Finance, The Deal).
