On December 31, 2025, pursuant to that certain Agreement and Plan of Merger, dated as of August 11, 2025 by and among the Registrant, Bandit Parent, LP, a Delaware limited partnership (“Parent”) and Bandit Merger Sub, Inc., a Delaware corporation and an indirect wholly owned subsidiary of Parent (“Merger Sub”), Merger Sub merged with and into the Registrant (the “Merger”), with the Registrant surviving as an indirect wholly owned subsidiary of Parent.

As a result of the consummation of the Merger, the Registrant has terminated any and all offerings of the Registrant’s securities pursuant to its existing registration statements under the Securities Act of 1933, as amended, including the Registration Statements. The Registrant, by filing this Post-Effective Amendment No. 1, hereby terminates the effectiveness of the Registration Statements and, in accordance with undertakings made by the Registrant in the Registration Statements to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance that remain unsold or unissued at the termination of the offering, the Registrant hereby removes from registration all such securities of the Registrant registered pursuant to the Registration Statements that remain unsold or unissued as of the date hereof. The Registration Statements are hereby amended, as appropriate, to reflect the deregistration of such securities.

The foregoing description of the Merger, the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by the Merger Agreement, which is included as Exhibit 2.1 in the Registrant’s Form 8-K filed with the SEC on August 11, 2025.
