Item 3.02. Unregistered Sales of Equity Securities.

As previously reported on its Current Reports on Form 8-K filed on June 13, 2025 and July 1, 2025, Indaptus Therapeutics, Inc. (the “Company”) completed a private placement (the “Private Placement”) of convertible promissory notes (the “Notes”) and warrants (the “Warrants”) to certain accredited investors (the “Purchasers”) in two closings on June 12, 2025 and June 30, 2025, for total gross proceeds of approximately $5.7 million, before deducting the placement agent’s fees and other offering expenses.

In accordance with the terms of the Notes, on July 27, 2025 (the “Conversion Date”), the Notes were automatically converted into an aggregate of 545,598 shares (the “Conversion Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), based on a conversion price of $8.3024, which is equal to 80% of the average Nasdaq closing price for the five trading days immediately preceding and including the Conversion Date. In addition, for Purchasers whose conversions would have exceeded ownership limits of 4.99% or 9.99%, the Company issued pre-funded warrants to purchase an aggregate of 146,763 shares of Common Stock (the “Pre-Funded Warrants”) which represent the portion that would otherwise exceed the applicable threshold. The Pre-Funded Warrants have substantially the same terms as the Warrants, but with an exercise price for the Pre-Funded Warrants of $0.01 per share and no expiration date.

In connection with the automatic conversion of the Notes, the Company issued to the Purchasers Warrants to purchase an aggregate of 1,384,722 shares of Common Stock exercisable at $8.3024 per share and with a term ending on July 27, 2030. In addition, the Company issued to Paulson Investment Company, Inc. (“Paulson”) and its designees placement agent warrants (the “Placement Agent Warrants”) to purchase an aggregate of 83,083 shares of Common Stock. The Placement Agent Warrants have the same terms as the Warrants (except that the Placement Agent Warrants contain a cashless exercise feature that is not dependent on the registration of the underlying shares) and expire on the fifth anniversary of the issue date.

Based in part upon the representations of the Purchasers in the securities purchase agreements and Paulson in the Placement Agent Agreement, entered into in connection with the Private Placement, the offering and sale of the Conversion Shares, the Warrants, the Pre-Funded Warrants, the Placement Agent Warrants and the shares of common stock issuable upon the exercise of the foregoing warrants will be exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and/or Rule 506(c) of Regulation D promulgated under the Securities Act. The issuances and sales of the Conversion Shares, the Warrants, the Pre-Funded Warrants, the Placement Agent Warrants and the shares of common stock issuable upon the exercise of the foregoing warrants will not be registered under the Securities Act or any state securities laws, and such securities may not be offered or sold in the United States absent registration with the Securities and Exchange Commission or an applicable exemption from the registration requirements.

Item 5.07. Submission of Matters to a Vote of Security Holders.

On July 25, 2025, the Company held a special meeting of shareholders (the “Special Meeting”) to consider two proposals in connection with the Private Placement. A total of 236,794 shares of the Company’s Common Stock were present in person or represented by proxy at the Special Meeting, representing approximately 41.35% of the Company’s outstanding Common Stock as of the June 16, 2025 record date, which total constituted a quorum for the Special Meeting in accordance with the Company’s bylaws.
