Revelation Biosciences Inc. Announces 1-for-35 Reverse Stock Split effective February 1, 2023 and

Results of Special Meeting of Stockholders

San Diego, CA – January 31, 2023 – Revelation Biosciences Inc. (NASDAQ: REVB) (the “Company” or “Revelation”), announced today that, on February 1, 2023, the Company will implement a 1-for-35 reverse split of its common stock following approval at its Special Meeting of Stockholders held on January 30, 2023. The reverse stock split will be effective as of the morning of February 1, 2023, and the Company’s common stock will trade on a post-split basis at the beginning of trading on the same date under the existing trading symbol “REVB.” The CUSIP number for the common stock following the reverse stock split will be 76135L 309.  At the meeting, the stockholders also approved an increase in the authorized common stock to 500,000,000 shares and ratified the appointment of Baker Tilly US, LLP as independent public accountants to the Company.

The reverse stock split is intended to increase the market price per share of the Company’s common stock to regain compliance with the minimum bid continued listing requirement of The Nasdaq Capital Market. The Company intends to continue to pursue additional actions to satisfy the exchange’s minimum stockholders’ equity requirement. The reverse stock split will reduce the number of shares of the Company’s common stock currently outstanding to approximately 672,460 shares. Proportionate adjustments will be made to the conversion and exercise prices of the company’s warrants, restricted stock unit awards, stock options and to the number of shares issued and issuable under the Company’s equity incentive plans.

Information for Stockholders

Upon the effectiveness of the reverse stock split, each thirty-five shares of the Company’s issued and outstanding common stock will be automatically combined and converted into one issued and outstanding share of common stock. The reverse stock split will affect all stockholders uniformly and will not alter any stockholder’s relative interest in the Company’s equity, except to the extent that the reverse stock split would have resulted in a stockholder owning a fractional share. Holders of common stock otherwise entitled to a fractional share as a result of the reverse stock split will automatically be entitled to receive an additional fraction of a share of common stock to round up to the next whole share. The reverse stock split will not change the par value of the common stock or modify the rights or preferences of the common stock. The Company’s transfer agent, Continental Stock Transfer & Trust Co., will maintain the book-entry records for the Company’s common stock. Registered stockholders holding pre-split shares of the Company’s common stock electronically in book-entry form are not required to take any action to receive post-split shares. Stockholders owning shares via a broker, bank, trust or other nominee will have their positions automatically adjusted to reflect the reverse stock split, subject to such broker’s particular processes, and will not be required to take any action in connect with the reverse stock split. Continental Stock Transfer & Trust Co. can be reached at (212) 509-4000 or (800)-509-5586.
