Item 1.01 Entry into a Material Definitive Agreement.

On September 10, 2025, Inno Holdings Inc. (the “Company”) entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain institutional investors, pursuant to which the Company offered, in a registered direct offering, 1,200,000 shares of its common stock, at a purchase price of $3.60 per share and pre-funded warrants to purchase up to 800,000 shares of common stock, at a purchase price of $3.59999 per pre-funded warrant (equal to $3.60 minus the exercise price of $0.00001 per pre-funded warrant). Upon closing of the offering, 285,000 pre-funded warrants were exercised for the issuance of 285,000 shares of the Company’s common stock.

The offering was made pursuant to that certain Registration Statement on Form S-3 (File No. 333-284054), which was previously filed with the U.S. Securities and Exchange Commission (the “SEC”) and declared effective by the SEC on January 10, 2025, including the Prospectus contained therein and a prospectus supplement dated September 10, 2025 filed with the SEC on September 11, 2025.

The closing of the offering occurred on September 11, 2025. The Company received net proceeds of approximately $6.7 million from the offering, after deducting the estimated offering expenses payable by the Company, including the placement agent fees. The Company intends to use the net proceeds from the offering for general corporate purposes, including working capital.

In connection with the offering, the Company entered into a placement agent agreement (the “Placement Agent Agreement”), on September 9, 2025, with Aegis Capital Corp. (the “Placement Agent”), as the exclusive placement agent for the offering. The Company paid the Placement Agent a cash fee of 5.0% of the aggregate gross proceeds received in the offering and reimbursed certain expenses of the Placement Agent.

The foregoing summaries of the Securities Purchase Agreement and the Placement Agent Agreement do not purport to be complete and are subject to, and qualified in their entirety by, copies of such documents which are filed as exhibits to this report and are incorporated by reference herein.

McCarter & English, LLP, counsel to the Company, delivered opinions as to the legality of the issuance and sale of the shares and pre-funded warrants, and the legality and enforceability of the pre-funded warrants, as applicable, copies of which are filed as exhibits to this report.

Item 8.01 Other Events.

On September 10, 2025, the Company issued a press release announcing the pricing of the offering. On September 11, 2025, the Company issued a press release announcing the closing of the offering. Copies of the press releases are filed as exhibits to this report.
