Entry into a Material Definitive Agreement.

On August 13, 2025, TSS, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Lucid Capital Markets, LLC, as the sole book-running manager (the “Underwriter”), relating to the previously announced underwritten public offering (the “Offering”) by the Company of 3,000,000 shares (the “Underwritten Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”).

The public offering price of the Underwritten Shares was $17.00 per share, and the Underwriters agreed to purchase the Underwritten Shares from the Company pursuant to the Underwriting Agreement at a price of $16.15 per share (the “Purchase Price”). Under the terms of the Underwriting Agreement, the Company granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 450,000 shares of Common Stock (the “Over-Allotment Shares” and, together with the Underwritten Shares, the “Shares”) at the Purchase Price. The Underwriters elected to exercise this option on August 13, 2025.

The Company estimates that, net of the underwriter’s commission, proceeds to the Company will be approximately $55.3 million.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties and other terms and conditions customary in agreements of this type.
