Broad incumbents

• Arkema: Arkema's Forane refrigerant portfolio includes HFCs, HFOs and reclaimed refrigerants serving HVAC, refrigeration and foam-blowing markets. It competes with Hudson across the refrigerant lifecycle and is exposed to the same AIM Act transition dynamics.
• Clean Harbors: Clean Harbors is a North American environmental and industrial services company with hazardous waste management, recycling and remediation capabilities. It provides broader environmental services that include refrigerant and specialty gas handling, overlapping with Hudson's reclamation and SF6 services.
• Republic Services (US Ecology): Republic Services acquired US Ecology in 2022, a former hazardous and industrial waste management specialist. US Ecology's former specialty waste operations are a directional peer to Hudson's reclamation business, now embedded within a much larger environmental services platform.
• Chemours: Chemours is a major manufacturer of Freon-brand HFC refrigerants and Opteon-brand HFO refrigerants. While primarily a producer rather than reclaimer, it directly competes with Hudson in supplying refrigerants to commercial and industrial customers, including HFC volumes now under AIM Act phase-down.
• Honeywell (Solstice Advanced Materials): Honeywell's Solstice Advanced Materials business is a leading manufacturer of low-GWP HFO refrigerants and is currently Hudson's licensing partner for R-448A/R-449A. It overlaps with Hudson in the supermarket and commercial refrigeration end markets and represents both a partner and competitive threat as it expands downstream.
• Orbia (Mexichem): Orbia's Polymer Solutions (Vestolit) and Fluent brands produce refrigerants and fluorinated specialties globally. Orbia competes with Hudson in refrigerant manufacturing and supply and is a participant in the broader HFC/HFO value chain.

Emerging players

• Heritage-Crystal Clean: Heritage-Crystal Clean provides environmental and industrial services including used oil and parts cleaning, with adjacency to specialty chemicals and waste streams. It is a smaller-scale peer with overlapping environmental services exposure relevant to Hudson's industrial customer base.

Regional players

• Tazzetti: Tazzetti is a European-headquartered specialty gas and refrigerant company with reclamation operations serving industrial and commercial customers. It is a direct reclamation peer to Hudson but operates predominantly in EMEA rather than North America.
• Refex Industries: Refex Industries is an Indian refrigerant manufacturer and reclaimer serving HVAC, automotive and industrial customers across South Asia. It is a direct functional peer in refrigerant reclamation but does not operate in Hudson's core U.S. market.

Direct peers

• A-Gas: A-Gas is a global specialty gas and refrigerant services company with refrigerant recovery, reclamation and lifecycle management operations across the Americas, EMEA and Asia-Pacific. It is the most direct competitor to Hudson in refrigerant reclamation and gas services.
