Risk factors and legal proceedings

The risks HUDSON TECHNOLOGIES INC /NY names in Item 1A of its 10-K filed Mar 16, 2026: 15 risks under these headings, as written.4

  • Risks Related to Business Strategy and Operations
  • Our revenues, results of operations and cash flows could be materially and adversely affected by changes in commodity prices.
  • Our existing and future debt obligations could impair our liquidity and financial condition.
  • We may need additional financing to satisfy our future capital requirements, which may not be readily available to us.
  • Adverse weather or economic downturn could adversely impact our financial results.
  • Financial Covenants
  • Our business is impacted by customer concentration.
  • Our information technology systems, processes, and sites may suffer interruptions, failures, or attacks which could affect our ability to conduct business.
  • Risks Related to Regulatory and Environmental Matters
  • The nature of our business exposes us to potential liability.
  • Our business and financial condition is substantially dependent on the sale and continued environmental regulation of refrigerants.
  • A number of factors could negatively impact the price and/or availability of refrigerants, which would, in turn, adversely affect our business and financial condition.
The other 6 risks
  • Issues relating to potential global warming and climate change could have an impact on our business.
  • Risks Related to Our Common Stock and Other General Risks
  • As a result of competition, and the strength of some of our competitors in the market, we may not be able to compete effectively.
  • We have the ability to designate and issue preferred stock, which may have rights, preferences and privileges greater than Hudson’s common stock and which could impede a subsequent change in control of us.
  • If our common stock were delisted from NASDAQ it could be subject to “penny stock” rules which would negatively impact its liquidity and our shareholders’ ability to sell their shares.
  • Our management has significant control over our affairs.
  • We may fail to successfully integrate any additional acquisitions made by us into our operations.

Legal proceedings

The Company’s current contract with DLA expires in July 2026. In October 2025, the DLA awarded a new five-year contract with a five-year renewal option to the Company (the “2025 DLA Contract”). Following issuance of the new contract, a competitor filed a bid protest at the U.S. Court of Federal Claims, challenging the DLA’s evaluation of proposals and the contract award to the Company. As the recipient of the 2025 DLA Contract, the Company is a party to the bid protest. In response, the DLA is reviewing its evaluation to determine whether corrective action is necessary and has rescinded the 2025 DLA Contract award during this process. While the bid protest and corrective action is pending, the Company will continue providing logistics support under its existing contract which runs through July 2026.
