Hudson Technologies is a cheap option on refrigerant scarcity dated by federal law. A 2020 statute cuts HFC supply from 60% of baseline today to 30% on January 1, 2029, and EPA moves keeping legacy high-GWP equipment in service only add demand. From 2029 much servicing must use reclaimed refrigerant, and Hudson is a top US reclaimer. It trades near 1x sales with net cash. Risks: inventory overhang defused the 2024 cut, a defense contract is in rebid, and the reclaim mandate is softer. x.comÂ
