Sector Focus
Cronus Partners maintains a diversified advisory practice with primary expertise concentrated in Environmental Services—a specialization that reflects both the firm's deep commitment to this sector and the growing importance of environmental technologies and solutions. Beyond environmental services, the firm actively advises on transactions across aerospace and defense, manufacturing (both discrete and process), maritime industries, energy, and business services sectors.
The Environmental Services focus encompasses water treatment and remediation technologies, PFAS treatment solutions, separation and flotation systems, and industrial processing equipment. Recent client work includes advisory relationships with firms developing cutting-edge water treatment technologies, such as patented Suspended Air Flotation (SAF®) systems that address critical environmental challenges.
The firm's manufacturing expertise spans precision machining, contract manufacturing, specialized chemicals, and industrial components. Its aerospace and defense practice includes MRO (maintenance, repair, overhaul) facilities, aircraft component manufacturers, and avionics/systems integrators. In maritime, the firm advises shipping services, marine engineering, and port operations companies.

Process & Fee Structure
Cronus Partners typically runs institutional-quality M&A processes, managing comprehensive buyer outreach, preparing management presentations, organizing data rooms, and supporting due diligence. The firm generally works on a retainer-plus-success-fee basis, consistent with middle-market M&A advisory norms. Engagement structures typically include monthly retainers credited against success fees upon deal close. The firm generally does not accept engagements below $10M-$15M in enterprise value.
Buyer Network
Cronus has demonstrated consistent access to a diverse buyer network including:
- Private Equity Firms: Altus Capital Partners, Genstar Capital, Industrial Growth Partners, and other middle-market PE firms focused on add-on acquisitions and platform builds

The firm's aerospace network is particularly strong, with demonstrated ability to facilitate transactions between MRO/manufacturing companies and both strategic buyers and PE investors.
