a leading provider of innovative and sustainable refrigerant products and services to the Heating, Ventilation, Air Conditioning and

Refrigeration Industry – and one of the nation’s largest refrigerant reclaimers – today announced the appointment of

Alan brings 40

and venture capital investing. He is currently Chief Executive Officer of Catalyst Capital Markets, a firm specializing in capital markets

advisory and transaction management. Previously he was Vice Chairman of the Corporate & Institutional Bank of PNC Financial

firm, where he served as Co-Chief Executive Officer until his retirement in 2020. Prior to founding Solebury Capital, Alan held several

senior-level positions at Credit Suisse First Boston, including as Co-Head of Equity Capital Markets for the Americas. He also chaired

Credit Suisse’s Equity Valuation Committee from 1999 to 2005 and sat on the firm’s Investment Banking Committee from 2001-2005.

He began his career at Salomon Brothers. Mr. Sheriff is a board director at Tailwind 2.0 Acquisition Corp., a Nasdaq-listed company.

Jeff has more than

30 years’ experience in senior operational and financial roles, including 20 years in the recycling, waste treatment and disposal

industries. Most recently he served as Chairman and Chief Executive Officer of Nasdaq-listed US Ecology Inc., an environmental services

company focused on industrial waste treatment, disposal, recycling and related industrial and emergency response services. He joined

Ken Gaglione, President

of Directors. Alan brings extensive financial and capital markets experience, and we are confident the Company will benefit from his

expertise going forward as we execute our strategic growth initiatives. We remain focused on growing our core businesses of refrigerant

sales, reclamation and services and believe that Alan will provide valuable perspective and insight as we identify the best pathways

to optimizing our go-to-market approach.

“Likewise,

we believe Jeff’s public-company leadership of US Ecology, Inc. a well-respected provider of environmental services, recycling

and industrial and emergency response services will strengthen our board’s capabilities as we move into Hudson’s next chapter.

Jeff’s wide-ranging knowledge and track record of success as an operational and financial leader in an adjacent industry will enable

His clear vision, leadership, financial acumen, and principled approach to business guided Hudson through its formative years and helped

build it into the company we know today. We would not be in the strong position we are today without Vinnie’s many contributions.”
