ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On July 15, 2026 Acme United Corporation (the “Company”) entered into a new $65 million syndicated credit facility with HSBC Bank USA, National Association. (HSBC) and City National Bank, a U.S. subsidiary of Royal Bank of Canada. The new facility, which replaces the Company’s prior $65 million credit facility with HSBC that was scheduled to expire on May 31, 2027, is intended to provide liquidity for growth, acquisitions, dividends, and other business activities. The new agreement expires on July 15, 2029. HSBC serves as the administrative agent for the syndicate.

Borrowings bear interest at Term SOFR plus an applicable margin (ranging from 2.00%–2.75%) determined by the Company’s Net Funded Debt to EBITDA ratio. A commitment fee of 0.25% per annum accrues on unused commitments and is paid monthly. The Credit Agreement is secured by a first-priority lien on substantially all assets of the Company.

The new Credit Agreement contains customary affirmative and negative covenants, representations and warranties and other terms which are materially similar to those of the prior credit agreement. These provisions include the following quarterly financial maintenance covenants: (i) maximum Net Funded Debt to EBITDA ratio of 3.75 to 1.00 and (ii) minimum Fixed Charge Coverage Ratio of 1.10 to 1.00. It also contains customary events of default, including payment defaults, covenant breaches, cross-default with material indebtedness, bankruptcy events, and a change of control, upon which payment of outstanding amounts may be accelerated.

On July 15, 2026, the opening balance under the new credit facility was $28.5 million, an amount equal to the payoff amount paid by the Company to HSBC on that date in connection with the termination of the former credit facility.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement, Revolving Notes and a Security Agreement, copies of which appear as Exhibits 10.1-10.4 to this Current Report on Form 8-K.
