Item 1.01. Entry into a Material Definitive Agreement.

Registered Direct Offering

On October 8, 2025, bioAffinity Technologies, Inc. (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with institutional investors (the “Purchasers”), pursuant to which the Company agreed to issue to the Purchasers in a registered direct offering (the “Offering”), 720,000 shares (the “Shares”) of the Company’s common stock, par value $0.007 per share (the “Common Stock”).

The Offering closed on October 9, 2025 (the “Closing Date”), and the Company received aggregate gross proceeds of approximately $1.8 million before deducting placement agent fees and other offering expenses payable by the Company. The Shares are being offered by the Company pursuant to a shelf registration statement on Form S-3 (File No. 333-275608), which was declared effective by the Securities and Exchange Commission on November 27, 2023 (as amended from time to time, the “Registration Statement”).

Pursuant to the terms of the Purchase Agreement, until November 14, 2025, the Company has agreed not to issue (or enter into any agreement to issue) any shares of Common Stock or Common Stock Equivalents (as defined in the Purchase Agreement), subject to certain exceptions. The Company has further agreed not to enter into an agreement involving any Variable Rate Transaction (as defined in the Purchase Agreement) until six (6) months following the Closing Date, provided however, that the prohibition on “at the market offerings” and equity lines of credit shall expire on November 14, 2025. In addition, each of the Company’s officers and directors have entered into lock-up agreements with the Company pursuant to which each of them has agreed not to, for a period of 60 days from the Closing Date, offer, sell, transfer or otherwise dispose of the Company’s securities, subject to certain exceptions.

WallachBeth Capital, LLC acted as the exclusive placement agent (the “Placement Agent”) on a “reasonable best efforts” basis, in connection with the Offering pursuant to that certain placement agency agreement, dated October 8, 2025 (the “Placement Agency Agreement”), by and between the Company and the Placement Agent. Pursuant to the Placement Agency Agreement, the Placement Agent will receive a cash fee of 8.0% of the aggregate gross proceeds paid to the Company for the securities sold in the Offering and reimbursement of certain out-of-pocket expenses up to a maximum of $75,000.

The foregoing summaries of the Offering, including the securities to be issued in connection therewith, the forms of Placement Agency Agreement and Purchase Agreement, do not purport to be complete and are qualified in their entirety by reference to the definitive transaction documents, copies of which are attached hereto as Exhibits 1.1 and 10.1, respectively, and are each incorporated herein by reference.

The Company notes that the representations, warranties and covenants made by the Company in any agreement that is incorporated by reference herein were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements. In addition, the assertions embodied in any representations, warranties and covenants contained in such agreements may be subject to qualifications with respect to knowledge and materiality different from those applicable to security holders generally. Moreover, such representations, warranties or covenants were accurate only as of the date when made, except where expressly stated otherwise. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of the Company’s affairs at any time.

An opinion of Sheppard, Mullin, Richter & Hampton LLP regarding the validity of the Shares being issued and sold in the registered direct offering is filed as Exhibit 5.1.

This Current Report on Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy, and these securities cannot be sold in any state or jurisdiction in which this offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any state or jurisdiction.
