Item 1.01. Entry into a Material Definitive Agreement As previously disclosed, on October 20, 2025, Co-Diagnostics, Inc., a Utah corporation (the “Company”), entered into an equity distribution agreement (the “Original Equity Distribution Agreement”) with Maxim Group LLC (“Maxim”). On July 27, 2026, the Company and Maxim entered into an amendment to the Original Equity Distribution Agreement (the “Equity Distribution Agreement Amendment”), which, among other things, removed the fixed aggregate dollar limitation on sales under the Original Equity Distribution Agreement, such that future offers and sales of our Common Stock will be limited solely by the amount of Common Stock currently registered and available for issuance under our effective registration statement. The offer and sale of the shares is being made pursuant to the Shelf Registration Statement (Registration No. 333-295803) and the related prospectus supplement dated July 27, 2026 (the “Prospectus Supplement”) filed by the Company with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended. The foregoing description of the Equity Distribution Agreement Amendment is only a summary and is qualified in its entirety by reference to the full text of the Equity Distribution Agreement Amendment, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference. In connection with the Company’s entry into the Equity Distribution Agreement Amendment and filing of the Prospectus Supplement, the Company also agreed with the investors under the Securities Purchase Agreement dated May 19, 2026, to extend the period during which the Company will not issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock or file any registration statement or prospectus, or any amendment or supplement thereto to 5:00 pm Eastern Time on August 14, 2026. The legal opinion of Dorsey & Whitney LLP relating to the shares being offered pursuant to the Equity Distribution Agreement (as amended by the Equity Distribution Agreement Amendment) and the Prospectus Supplement is filed as Exhibit 5.1 to this Current Report on Form 8-K. This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy the shares as discussed herein, nor shall there be any sale of the shares in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
