Item 1.01 Entry into a Material Definitive Agreement

On September 14, 2025, Sidus Space, Inc. (the “Company”) entered into a placement agency agreement (the “Placement Agency Agreement”) with ThinkEquity LLC (“the “Placement Agent”), pursuant to which the Company agreed to issue and sell directly to investors, in a best efforts offering (the “Offering”) an aggregate of 9,800,000 shares (the “Shares”) of the Company’s Class A common stock, par value $0.0001 (the “Common Stock”), at an offering price of $1.00 per Share.

The Shares were offered and sold by the Company pursuant to the Company’s effective registration statement on Form S-3 (File No. 333-273430), including a base prospectus, filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 26, 2023 and declared effective on August 14, 2023

The closing of the Offering is expected to occur on September 16, 2025, subject to the satisfaction of customary closing conditions. The gross proceeds to the Company from the Offering are expected to be approximately $9.8 million, before deducting placement agent fees and expenses and estimated offering expenses payable by the Company. The Company intends to use the net proceeds received from the Offering for working capital and general corporate purposes.

Pursuant to the Placement Agency Agreement, the Company agreed to pay the Placement Agent a cash fee equal to 7.0% of the aggregate purchase price paid by the purchasers in the Offering. The Company also agreed to reimburse the Placement Agent for all reasonable and out-of-pocket expenses incurred in connection with the Placement Agent’s engagement, including reasonable fees and expenses of the Placement Agent’s legal counsel and due diligence analysis in an amount not to exceed $125,000. In addition, the Company agreed to issue to ThinkEquity or its designees warrants (the “Placement Agent Warrants”) to purchase up to an aggregate of 490,000 shares of the Company’s Common Stock. The Placement Agent Warrants are exercisable immediately upon issuance at an exercise price of $1.25 per share and have a term of exercise equal to five years from the date of issuance.

The Placement Agency Agreement contains customary representations and warranties, agreements and obligations, conditions to closing and termination provisions. The foregoing descriptions of terms and conditions of the Placement Agency Agreement and the Placement Agent Warrants do not purport to be complete and are qualified in their entirety by the full text of the form of the Placement Agency Agreement and the form of Placement Agent Warrant, copies of which are attached hereto as Exhibits 1.1, and 4.1, respectively.
