Coleman , President and Chief Executive Officer of Hudson Technologies commented , “ We are pleased to have delivered strong second quarter results as demonstrated by substantial revenue growth and significantly improved profitability . Our performance was driven by increased demand as well as favorable pricing trends across our portfolio of refrigerants . We view the selling season as a nine - month period , and the second quarter has historically been a strong quarter for us as it typically coincides with warmer weather in the North and Northeast resulting in the start - up of cooling systems . During the second quarter , our business also benefitted from the favorable impact of the U.S. economy reopening . As we move through the balance of our selling season , we're optimistic about the activity and interest we're seeing for our products in the marketplace . " Additionally , from a regulatory perspective , we're looking forward to the anticipated publication of HFC allocations in September as the allocation portion of the AIM Act goes into effect . When the allocations become public , we'll have more visibility around how the industry will be positioned to supply the large and growing installed base of HFC systems as virgin production begins it phasedown starting in 2022. The AIM Act establishes a cumulative 40 % reduction in the baseline by 2024 and we anticipate that reclamation will be critical to maintaining necessary supply during this HFC phasedown period . Given our reclamation capabilities and robust distribution network , Hudson is uniquely positioned as both a supplier and a reclaimer , to meet potential supply shortfalls as virgin HFC production is phased down to 15 % in the year 2036. We believe the upcoming HFC phasedown represents a tremendous long - term growth opportunity and will create a favorable environment for us to capture additional business with our sustainable , reclaimed refrigerant offerings , " Mr. Coleman concluded .
