Item 8.01. Other Events.
On April 9, 2026, Theriva Biologics, Inc. (the
“Company”) called to order its Special Meeting of Stockholders (the “Special Meeting”). At that time, there were
not present or represented by proxy a sufficient number of shares of the Company’s common stock to constitute a quorum. As a result,
the Company was not able to convene the Special Meeting. The Company has determined to call a new meeting of stockholders to seek approval
of the warrant exercise proposal and adjournment proposal set forth in the definitive proxy statement filed with the Securities Exchange
Commission (the “SEC”) by the Company on March 16, 2026. The Company intends to file with the SEC and mail proxy materials
to its stockholders that will include information regarding the date and time of the new meeting, as required.
Under that certain warrant inducement agreement
(the “Inducement Agreement”), dated October 16, 2025, by and between the Company and certain institutional investors,
the Company agreed to use its reasonable best efforts to call a stockholder meeting within 60 days following the closing of the transactions
contemplated by the Inducement Agreement for the purpose of seeking approval of the issuance of up to an aggregate of 16,184,560
shares of the Company’s common stock upon the exercise of certain common stock purchase warrants (“New Warrants”)
issued pursuant to the Inducement Agreement (“Stockholder Approval”). The purpose of the Special Meeting was to seek such
Stockholder Approval. Because the Company was not able to convene the Special Meeting, unless waived by the investors, the Company will
be required under the Inducement Agreement to continue to call an additional meeting of stockholders every 60 days thereafter to
seek Stockholder Approval until the earlier of the date on which Stockholder Approval is obtained or the New Warrants are no longer outstanding.
SIGNATURES
Pursuant to the requirements
of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto
duly authorized.
