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

On September 11, 2026, Quality Industrial Corp., a Nevada corporation (the “Company”), filed a Certificate of Withdrawal of Certificate of Designation (the “Certificate of Withdrawal”) with the Secretary of State of the State of Nevada to withdraw the Certificate of Designation of Series A Preferred Stock that was originally filed on April 4, 2018 (the “Certificate of Designation”). The Certificate of Designation created a series of preferred stock designated as Series A Preferred Stock, par value $0.001 (“Series A Preferred Stock”). No shares of Series A Preferred Stock were outstanding at the time of the withdrawal. The withdrawal was authorized by a resolution of the Company’s board of directors.

As a result of the filing of the Certificate of Withdrawal, the Series A Preferred Stock is no longer a designated series of the Company’s preferred stock, and all references to the Series A Preferred Stock in the Company’s charter documents are of no further force or effect. The shares of preferred stock previously designated as Series A Preferred Stock have been returned to the status of authorized but undesignated shares of preferred stock of the Company.

The foregoing description of the Certificate of Withdrawal is qualified in its entirety by reference to the full text of the Certificate of Withdrawal, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.
