Registration Statement on Form S-3 (File No. 333-262231) filed with the SEC on January 19, 2022, registering an indeterminate number of (a) shares of Everbridge’s common stock, par value $0.001 per share (“Common Stock”), (b) shares of Everbridge’s preferred stock, par value $0.001 per share (“Preferred Stock”), (c) debt securities, and (d) warrants to purchase Common Stock.

Registration Statement on Form S-3 (File No. 333-229239) filed with the SEC on January 14, 2019, registering an indeterminate number of (a) shares of Common Stock, (b) shares of Preferred Stock, (c) debt securities, and (d) warrants to purchase Common Stock.

On July 2, 2024, pursuant to the Amended and Restated Agreement and Plan of Merger, dated as of February 29, 2024 (the “Merger Agreement”), by and among Everbridge, Everbridge Holdings, LLC, a Delaware limited liability company (formerly known as Project Emerson Parent, LLC) (“Parent”), and Project Emerson Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), which amends and restates the previously announced Agreement and Plan of Merger, dated as of February 4, 2024, by and among Everbridge, Parent and Merger Sub, Merger Sub merged with and into Everbridge (the “Merger”), with Everbridge continuing as the surviving corporation of the Merger and a wholly owned subsidiary of Parent.

As a result of the Merger, Everbridge has terminated any and all offerings of Everbridge’s securities pursuant to its existing registration statements under the Securities Act of 1933, as amended, including the Registration Statements. In accordance with undertakings made by Everbridge in the Registration Statements to remove from registration, by means of a post-effective amendment, any securities that had been registered under the Registration Statements for issuance that remain unsold at the termination of the offering, Everbridge hereby removes from registration all such securities of Everbridge registered pursuant to the Registration Statements that remain unsold or otherwise unissued as of the date hereof. The Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such securities, and Everbridge hereby terminates the effectiveness of the Registration Statements.
