Amentum Holdings

Amentum Holdings

Amentum Holdings was established in 2015 by Jake Kloberdanz, building a permanent-capital structure designed to acquire and operate private infrastructure companies. The firm's wealth origin is not publicly disclosed, and it does not market itself as a single-family office. Instead, Amentum operates as an investment holding company, deploying capital directly into operating businesses rather than through limited partnership fund structures. The founding thesis holds that the energy transition requires patient, indefinite-duration capital — a mismatch with traditional private equity's 10-year fund life. Amentum targets mid-market infrastructure businesses across the decentralized energy and electrification landscape. The firm's portfolio spans electric vehicle charging infrastructure, distributed solar generation, energy storage, and fleet electrification services. It acquires controlling stakes in founder-led companies, then provides operational resources to scale them. Confirmed investments include Electrify America, the public EV charging network spun out of Volkswagen's Dieselgate settlement, which Amentum backed alongside other institutional partners. The geographic footprint concentrates on North America, with operating subsidiaries serving US commercial and municipal fleets, logistics hubs, and retail charging corridors. Deployment data and total committed capital are not publicly disclosed. The firm maintains a lean leadership structure centered on Kloberdanz, with operating partners embedded at the portfolio-company level rather than a large centralized investment team. No public headcount is available. There are no disclosed adjacent vehicles, philanthropic foundations, or co-investor clubs. In May 2024, press reports confirmed Amentum's continued ownership stake in Electrify America as the network surpassed 4,000 charging stations across the United States, reflecting the holding-company model's patient-capital posture. Amentum's structural differentiator is its permanent-holding-company architecture. Where most infrastructure investors operate 10-to-15-year closed-end funds that must eventually sell assets to return capital, Amentum holds subsidiaries indefinitely. This eliminates forced exit timelines and allows acquired businesses to compound without transaction pressure. The model resembles Constellation Software's operating philosophy applied to energy infrastructure — buy, hold, improve permanently — but applied to a capital-intensive sector where competitors are almost exclusively fund-structured.
