Failure to Satisfy Listing Rule Form 8 K

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On October 16, 2024, Revelation Biosciences, Inc. (the "Company") received a letter (the "Minimum Bid Price Deficiency Letter") from the Listing Qualifications Department (the "Staff") of The Nasdaq Stock Market LLC ("Nasdaq"), notifying the Company that it was not in compliance with Nasdaq Listing Rule 5550(a)(2) which requires listed companies to maintain a minimum bid price of $1.00 per share (the "Minimum Bid Price Requirement").

Normally, a company would be afforded a 180-calendar day period to demonstrate compliance with the Minimum Bid Price Requirement. However, pursuant to Listing Rule 5810(c)(3)(A)(iv) the Company is not eligible for any compliance period specified in Rule 5810(c)(3)(A) because the Company effected one or more reverse stock splits over the prior two-year period with a cumulative ratio of 250 shares or more to one.

Separate from and in addition to the Minimum Bid Price Deficiency Letter, as previously disclosed, on August 14, 2024, the Company received a letter (the "Stockholders' Equity Requirement Deficiency Letter" and together with the Minimum Bid Price Deficiency Letter, the "Deficiency Letters") from the Staff of Nasdaq notifying the Company that it was not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires the Company to maintain a minimum of $2,500,000 in stockholders' equity for continued listing on The Nasdaq Capital Market (the "Stockholders' Equity Requirement"), nor is it in compliance with either of the alternative listing standards, market value of listed securities of at least $35 million or net income of $500,000 from continuing operations in the most recently completed fiscal year, or in two of the three most recently completed fiscal years. The Minimum Bid Price Deficiency Letter stated that the Company's Stockholders' Equity Requirement Deficiency serves as an additional basis per Nasdaq Listing Rule 5810(d)(2) for delisting the Company's securities from The Nasdaq Stock Market and that at a hearing in connection with the Minimum Bid Price Requirement, the Nasdaq Hearings Panel ("Panel") will consider the Company's Stockholders' Equity Requirement Deficiency as well. By virtue of the Company's financing activities during the third quarter, the Company believes it satisfied the Stockholders' Equity Requirement as of September 30, 2024.

The Company intends to take all reasonable measures available to regain compliance under the Nasdaq Listing Rules and remain listed on Nasdaq. The Company has the right to appeal the Deficiency Letters by requesting a hearing before an independent panel, which it intends to do prior to the deadline for filing such appeal. The hearing request would stay any suspension or delisting action pending the conclusion of the hearing process and the expiration of any additional extension period granted by the panel following the hearing. However, there can be no assurance that the Company will ultimately regain compliance with all applicable requirements for continued listing. Neither the Deficiency Letters nor the Company's noncompliance have an immediate effect on the listing or trading of the Company's common stock or warrants, which will continue to trade on The Nasdaq Capital Market under the symbols "REVB" and "REVBW," respectively.
