Item 1 7.01 ~~Entry~~Regulation ~~Into~~FD ~~a Material Definitive Agreement~~Disclosure.

On ~~June~~September 274, 2025, ~~Bone Biologics Corporation (~~the “Company”) ~~priced~~issued a ~~public~~press ~~offering~~release ~~(the “Offering”) of (i) 793,750 shares (the “Shares”) of its common stock, par value $0.001 per share (the “Common Stock”), together~~ with ~~Series D~~respect ~~warrants~~to (the ~~“Series~~CEO’s DLetter ~~Warrants”)~~ to ~~purchase~~Stockholders. ~~793,750~~A ~~shares~~copy of ~~Common Stock and Series E warrants (~~the ~~“Series~~ Epress ~~Warrants,”~~release ~~together~~is ~~with~~attached ~~the~~hereto ~~Series~~as DExhibit ~~Warrants, the “Warrants”) to purchase 793,750 shares of Common Stock at a combined public offering price of $4~~99.001 ~~per Share~~ and ~~accompanying~~incorporated ~~Warrants~~herein ~~and~~by (ii) pre-funded warrants (the “Pre-Funded Warrants”) to purchase 456,250 shares of Common Stock, together with Series D Warrants to purchase 456,250 shares of Common Stock and Series E Warrants to purchase 456,250 shares of Common Stock at a combined public offering price of $3reference.~~999 per Pre-Funded Warrant and accompanying Warrants.~~

Subject to certain ownership limitations described in the Warrants, (i) the Series D Warrants have an exercise price of $4.00 per share of Common Stock, are exercisable upon issuance and will expire five years from the date of issuance and (ii) the Series E Warrants have an exercise price of $4.00 per share of Common Stock, are exercisable upon issuance and will expire eighteen months from the date of issuance. The exercise price of the Warrants will be subject to adjustment for stock dividends, stock splits, reverse splits, and similar capital transactions as described in the Warrants.

Each Pre-Funded Warrant represents the right to purchase one share of Common Stock at an exercise price of $0.001 per share. Subject to certain ownership limitations described in the Pre-Funded Warrants, the Pre-Funded Warrants are immediately exercisable and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full. In the event of a fundamental transaction, as described in the Warrants and Pre-Funded Warrants, the holder will have the right to receive as alternative consideration, for each share of Common Stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of common stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of Common Stock for which the Series D Warrant, Series E Warrant or Pre-Funded Warrant is exercisable immediately prior to such event. In the event of certain fundamental transactions, holders of the Warrants will have the right to receive the Black Scholes Value of their Warrants calculated pursuant to a formula set forth in the Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the holders of Common Stock in such fundamental transaction.

A holder will not have the right to exercise any portion of the Warrants or the Pre-Funded Warrants if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or, at the election of the holder, 9.99%) 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 Warrants or the Pre-Funded Warrants.

In connection with the Offering, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors. The Purchase Agreement contains customary representations and warranties of the Company, termination rights of the parties, and certain indemnification obligations of the Company and ongoing covenants of the Company, including a prohibition on issuance of Common Stock or securities convertible, exercisable or exchangeable into Common Stock by the Company for a period of 60 days after the closing date of the Offering and a prohibition on the Company entering into variable rate transactions for a period of one year after the closing date of the Offering, subject to certain exceptions.

The net proceeds to the Company from the Offering were approximately $4.3 million, after deducting Placement Agent’s (as defined below) fees and other estimated offering expenses payable by the Company. The potential additional gross proceeds to the Company from the Warrants, if fully-exercised on a cash basis, will be approximately $10 million. The Company intends to use the net proceeds from the Offering to fund clinical trials, maintain and extend its patent portfolio, and for working capital and other general corporate purposes.

The Offering was made pursuant to the Company’s registration statement on Form S-1 (File No. 333-288282), which was declared effective by the Securities and Exchange Commission on June 27, 2025, and a preliminary and final prospectus thereunder. The closing of the Offering took place on June 30, 2025. After the closing of the Offering, the Company had 1,605,260 shares of Common Stock outstanding.

The Company engaged H.C. Wainwright & Co., LLC (the “Placement Agent”) as the exclusive placement agent for the Offering. The Placement Agent did not purchase or sell any securities, nor was it required to arrange the purchase or sale of any minimum number or dollar amount of securities. The Placement Agent agreed to use its reasonable best efforts to arrange for the sale of the securities in the Offering. The Company paid the Placement Agent an aggregate cash fee equal to 7.0% of the gross proceeds received by the Company from the Offering and a management fee equal to 1.0% of the aggregate gross proceeds from the Offering. The Company also reimbursed the Placement Agent for non-accountable expenses in an amount up to $35,000, its legal fees and expenses and other out-of-pocket expenses in the amount of up to $100,000, and its clearing expenses in the amount of $15,950. The Company also issued the Placement Agent or its designees warrants to purchase up to 75,000 shares of Common Stock (or 6.0% of the aggregate number of Shares and Pre-Funded Warrants sold in the Offering) (the “Placement Agent Warrants”). The Placement Agent Warrants have substantially the same terms as the Warrants, except that the Placement Agent Warrants have an exercise price equal to $5.00 and have a term of five years from the commencement of sales of the Offering.

The foregoing is only a summary of the Series D Warrants, the Series E Warrants, the Pre-Funded Warrants, the Placement Agent Warrants and the Purchase Agreement and does not purport to be a complete description thereof. Such descriptions are qualified in their entirety by reference to the Form of Series D Warrant, the Form of Series E Warrant, the Form of Pre-Funded Warrant, the Form of Placement Agent Warrant and the Form of Purchase Agreement, copies of which are incorporated by reference as Exhibits 4.1, 4.2, 4.3, 4.4 and 10.1, respectively, to this Current Report on Form 8-K and are incorporated by reference herein.
