Amendment Description Brownie’s Marine Group, Inc. (the “Company”) is filing this Amendment No. 2 (“Amendment”) to its Quarterly Report on Form 10-Q for the six months ended June 30, 2026, which was originally filed with the Securities and Exchange Commission (“SEC”) on August 4, 2026 (the “Original Report”). Following the amendment to the Original Report on August 24, 2026 (“Amendment No. 1”) to correct errors in reporting of net income, operating results, other income and net income for the three months ended June 30, 2026 and to report that the financial statements and related financial information in the Original Report should no longer be relied upon ( as reported in the Company’s Current Report on Form 8-K as filed with the SEC on August 24, 2026), it came to the Company’s attention that the Original Report had inadvertently referenced the period reported upon in the Explanatory Note as the six months ended June 30, 2025. This Amendment is being filed to correct such disclosure and correctly reference the six months ended June 30, 2026. Also, the Company has determined it appropriate to correct certain other immaterial errors described below:
