Item 1.01. Entry into a Material Definitive Agreement

On October 28, 2025, Co-Diagnostics, Inc., a Utah corporation (the “Company”), entered into a Securities Purchase Agreement (the “Purchase Agreement”) with two institutional investors (the “Investors”) named therein, pursuant to which the Company agreed to issue and sell, in a registered direct offering priced at-the-market under Nasdaq rules by the Company directly to the Investors (the “Offering”) (i) an aggregate of 12,002,272 shares (the “Shares”) of common stock, par value $0.001 per share, of the Company (“Common Stock”), at an offering price of $0.55 per Share and (ii) an aggregate of 725,000 pre-funded common stock purchase warrants (the “Pre-Funded Warrants”) to purchase 725,000 shares of Common Stock at an offering price of $0.5499 per Pre-Funded Warrant (the “Pre-Funded Warrant Shares”, and collectively with the “Pre-Funded Warrants” and “Shares”, the “Securities”). The Pre-Funded Warrants will have an exercise price of $0.0001 per share, will be exercisable immediately and will expire when exercised in full.

A holder will not have the right to exercise any portion of the Pre-Funded Warrants if the holder (together with its affiliates) would beneficially own in excess of 4.99% or 9.99%, as applicable, of the number of shares of Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrants.

The Shares will be offered by the Company pursuant to a prospectus supplement to a registration statement on Form S-3 (File No. 333-270628), which was filed with the Securities and Exchange Commission (the “Commission”) on March 16, 2023, and was declared effective by the Commission on April 6, 2023.

Also on October 28, 2025, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Maxim Group LLC (the “Placement Agent”) pursuant to which the Company engaged the Placement Agent as the exclusive placement agent in connection with the Offering. The Company agreed to pay the Placement Agent a cash fee equal to seven percent (7.0%) of the gross proceeds from the sale of the Securities. The Company also agreed to reimburse the Placement Agent for out-of-pocket expenses, including the reasonable fees of legal counsel not to exceed $50,000. The Placement Agency Agreement also contains representations, warranties, indemnification and other provisions customary for transactions of this nature.

The Offering is expected to close on October 29, 2025. The aggregate gross proceeds to the Company from the Offering will be approximately $7 million before deducting the Placement Agent’s fees and related offering expenses. The Company intends to use proceeds from the Offering for working capital and general corporate purposes.

The foregoing summaries of the Purchase Agreement, the Pre-Funded Warrant and the Placement Agency Agreement do not purport to be complete and are subject to, and qualified in their entirety by, such documents attached as Exhibits 10.1, 4.1 and 1.1, respectively, to this Current Report on Form 8-K, which are incorporated herein by reference.

This Current Report on Form 8-K does not constitute an offer to sell any securities or a solicitation of an offer to buy any securities, nor shall there be any sale of any securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

A copy of the opinion of Dorsey & Whitney LLP relating to the legality of the issuance and sale of the Shares is attached as Exhibit 5.1 hereto.

Item 8.01. Other Events

On October 28, 2025, the Company issued a press release (the “Pricing Press Release”) announcing the pricing of the Offering. A copy of the Pricing Press Release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

Forward Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
