Item 5.03 Amendment to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On April 30, 2026, Inno Holdings Inc., a Texas holding company (the “Company”) filed a Certificate of Amendment to the Certificate of Formations of the Company with the Secretary of State of the State of Texas (the “Certificate of Amendment”) that provides for a 1-for-20 reverse stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock, with no par value (the “Common Stock”). The Reverse Stock Split became effective on May 4, 2026 at 09:30 a.m., Eastern Time.

The foregoing description of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to the Certificate of Amendment, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K (this “Report”) and is incorporated herein by reference.

Item 7.01 Regulation FD Disclosure

On April 29, 2026, the Company issued a press release entitled “Inno Holdings Inc. Announces 1-for-20 Reverse Stock Split in Ongoing Nasdaq Compliance Efforts.” The Company announced that its board of directors has approved the Reverse Stock Split pursuant to the authorization grated from the annual meeting of the Company’s stockholders on March 2, 2026. A copy of the press release is attached as Exhibit 99.1 to this report.

The new CUSIP number for the Common Stock following the Reverse Stock Split is 4576JP406. Upon effectiveness of the Reverse Stock Split, every twenty (20) shares of the Company’s issued and outstanding Common Stock were reclassified and combined into one (1) share of Common Stock. Accordingly, the number of issued and outstanding shares of Common Stock of the Company was reduced from 50,413,224 shares before the Reverse Stock Split to 2,520,662 shares after the Reverse Stock Split. No fractional shares were issued; instead, any fractional entitlement was rounded up to the next highest whole number at the participant level.

The information in Item 7.01 of this Report, including the information in the press release furnished pursuant to this Item 7.01 of Form 8-K, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference in the filings of the registrant under the Securities Act of 1933, as amended, except in the event that the Company expressly states that such information is to be considered filed under the Exchange Act or incorporates it by specific reference in such filing.
