Item 3.01

Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On September 10, 2026, Bone Biologics Corporation (the “Company”) received a letter from the Listing Qualifications Staff of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based upon the closing bid price of the Company’s common stock for the last 30 consecutive business days, the Company no longer meets Nasdaq Listing Rule 5550(a)(2), which requires listed companies to maintain a minimum bid price of at least $1 per share.

Nasdaq Listing Rule 5810(c)(3)(A) provides a compliance period of 180 calendar days, or until March 9, 2027, in which to regain compliance with the minimum bid price requirement. If the Company evidences a closing bid price of at least $1 per share for a minimum of 10 consecutive business days during the 180-day compliance period, the Company will regain compliance. In the event the Company does not regain compliance with the $1 bid price requirement by March 9, 2027, the Company may be eligible for consideration of a second 180-day compliance period if it meets the continued listing requirement for market value of publicly held shares and all other initial listing standards for Nasdaq’s Capital Market, other than the minimum bid price requirement, and notifies Nasdaq of its intent to cure the minimum bid price deficiency.

If the Company fails to regain compliance with the Nasdaq continued listing standards, Nasdaq will provide notice that the Company’s common stock will be subject to delisting. The Company would then be entitled to appeal that determination to a Nasdaq hearings panel.

The notification has no immediate effect on the listing of the Company’s common stock on Nasdaq. The Company intends to monitor the closing bid price of its common stock and consider its available options in the event the closing bid price of its common stock remains below $1 per share. The Company intends to seek stockholder approval for a reverse stock split of its outstanding common stock at its upcoming annual meeting of stockholders. If the closing bid price of the common stock remains below $1 per share and the stockholders approve the proposal, the Company’s Board of Directors may authorize a reverse stock split to attempt to increase the per share price of the common stock and regain compliance with the Nasdaq Listing Standards.

Words like “attempt,” “believe,” “intend,” “may,” “will,” and “would” or the negative thereof or other variations thereon or comparable terminology, are used to identify forward-looking statements, although not all forward-looking statements contain these words.
