What Avem Partners buys
Avem Partners is a private equity firm in Santa Ana, California, founded in 2017 to buy lower middle market aerospace and defense companies in North America. It works only in that industry and favors engineering-driven precision manufacturers with certified quality systems, steady cash flow and repeat orders tied to aircraft, defense and space programs. Its stated targets are founder-owned companies with $15 million to $100 million of revenue, $3 million to $10 million of EBITDA and an enterprise value of $20 million to $100 million, with $15 million to $30 million invested per deal.
Avem takes majority control, leaves management with a meaningful ownership stake and uses limited debt. Its three partners have spent about two decades running and investing in aerospace suppliers, and a group of operating partners, all former industry executives, helps find deals, review them and serve on boards. Its last two acquisitions were financed with capital from True West Capital Partners, family offices, wealthy individuals and Avem's own principals. It now owns four Southern California manufacturers, most recently PAMCO, bought in April 2026.

Greymont’s take
How Avem Partners fits a seller
Avem fits founders of aerospace and defense machine shops, fittings makers, structures suppliers and specialty materials producers who want to sell control but keep a meaningful stake and stay involved. Because the partners know the industry well, diligence on certifications, customer approvals and program exposure can move faster than with a generalist buyer. Avem also showed with FMI Aerostructures in 2025 that it will buy a struggling supplier through a court-supervised sale.
Avem says it expects to spend three to five years improving each company and then sell it through a competitive auction run by an investment bank, so an owner who keeps equity should plan on a second sale within that window. Owners should ask how Avem plans to combine its holdings, since it describes building a scaled aerospace platform, and who will finance the deal, because its recent purchases relied on co-investors rather than a disclosed fund.
Questions owners ask
What size company does Avem Partners buy?
Its criteria call for founder-owned aerospace and defense companies with $15 million to $100 million of revenue, $3 million to $10 million of EBITDA and an enterprise value of $20 million to $100 million, with $15 million to $30 million invested per deal.
Does Avem invest outside aerospace and defense?
No. Avem says it focuses only on aerospace and defense, and it prefers engineering-driven precision manufacturers that carry regulated quality certifications and earn recurring revenue from long-running programs.
What has Avem bought recently?
In April 2026 it completed the purchase of PAMCO, a Sun Valley, California maker of fluid conveyance fittings, and in April 2025 it bought FMI Aerostructures, a Valencia airframe parts maker, through a court-supervised sale.
How long does Avem usually own a company?
Its strategy page describes three to five years of work on operations, governance and growth, followed by a competitive sale process run by an investment bank to get the best price for its investors.
