Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year. On July 27, 2026, Non-Invasive Monitoring Systems, Inc., a Florida corporation (the “Company”), filed Articles of Amendment to the Company’s Articles of Incorporation (“Articles of Amendment”) with the Secretary of State of the State of Florida to effect a reverse stock split of the Company’s issued and outstanding shares of common stock, par value $0.01 per share (“Common Stock”), at a ratio of 1-for-150. The Company’s board of directors (the “Board”), acting by unanimous written consent in lieu of a meeting on May 22, 2026, and the holders of a majority of the Company’s outstanding shares of Common Stock, acting by written consent in lieu of a special meeting on June 4, 2026, had previously authorized a reverse stock split of the Company’s Common Stock by a ratio of no less than 1-for-100 and no more than 1-for-500, with the exact ratio to be determined by the Board in its sole discretion. On July 13, 2026, the Board, acting by unanimous written consent in lieu of a meeting, authorized the Company to effect the reverse stock split at the ratio of 1-for-150. The reverse stock split became effective in the market on July 30, 2026 (the “Effective Time”). At the Effective Time, every one hundred and fifty (150) shares of the Company’s Common Stock were automatically combined into one (1) share of Common Stock. Any fractional shares of the Company’s Common Stock that would have resulted from the reverse stock split were rounded up to the nearest whole share. Immediately prior to the Effective Time, the Company had 154,810,655 shares of Common Stock issued and outstanding. Immediately following the Effective Time, the Company has 1,032,640 shares of Common Stock issued and outstanding. The reverse stock split did not change the par value of the Company’s Common Stock, which remains $0.01 per share, or the number of authorized shares of the Company’s Common Stock, which remains 400,000,000. The reverse stock split affects all holders of the Company’s Common Stock equally and does not affect any stockholder’s percentage ownership interest in the Company, except for de minimus adjustments that resulted from the treatment of fractional shares. The rights and privileges of the holders of shares of the Company’s Common Stock are substantially unaffected by the reverse stock split. As a result of the reverse stock split, the number of shares of the Company’s Common Stock that may be issued upon conversion or exercise of outstanding securities convertible into, or exercisable or exchangeable for, shares of the Company’s Common Stock, and the conversion or exercise prices for those securities, will also be ratably adjusted in accordance with their terms. The Company’s Common Stock is quoted on the OTC Markets, Pink Limited Market under the symbol “NIMU.” The reverse stock split will be reflected in the market quotation on or around the Effective Time under the new CUSIP number 655366607. Stockholders will have their positions automatically adjusted to reflect the reverse stock split and are not required to take any action.
