Hudson Technologies Inc /ny

A maker of refrigerant lifecycle management services, Hudson Technologies supplies, reclaims, and manages the gases that cool air conditioners, refrigerators, and commercial cooling systems across the HVACR industry. Founded in 1991 and based in Woodcliff Lake, New Jersey, the company grew to become one of the nation's largest refrigerant reclaimers, expanding through acquisitions like the 2017 purchase of Airgas-Refrigerants. Its motto, "one pound reclaimed is one pound not made," captures how it takes used refrigerant, purifies it, and sells it again instead of letting it escape into the atmosphere.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
