Perimeter Solutions vs Fortress: A Competitive and Legal History

Perimeter's PHOS-CHEK fire retardant currently has no competition. It has a five-year exclusive contract with the USFS to sell retardant and manage its fire bases. Entrants may proceed through the specification process, but may not be commercialised without compensating Perimeter or the company's approval to use its base equipment.

This setup is pretty unique. It's a legal sole source supplier for five years. But it hasn't always been this way. We have been following numerous legal battles and protests against the company for the last year.

This piece of research aims to curate our primary research on the historic and future potential competition to Perimeter's fire retardant business. It collates perspectives from our library and facts from public government and court filings.
