These Post-Effective Amendments (these "Post-Effective Amendments") are being filed by Assertio Holdings, Inc., a Delaware corporation (the "Registrant"), to deregister all securities remaining unissued and unsold under the following Registration Statements on Form S-3 (each, a "Registration Statement", and collectively, the "Registration Statements") filed with the U.S. Securities and Exchange Commission (the "SEC") by the Registrant or its predecessors, Assertio Therapeutics, Inc. and Depomed, Inc.:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Registration Statement on [Form S-3 (No. 333-277831), filed with the SEC on March 11, 2024](https://www.sec.gov/Archives/edgar/data/1808665/000110465924033094/tm247707-2_s3.htm) and declared effective on April 24,

· Registration Statement on [Form S-3 (No. 333-252368), filed with the SEC on January 25, 2021](https://www.sec.gov/Archives/edgar/data/1808665/000110465921006777/tm213908d1_s3.htm) and declared effective on

The Registrant is filing these Post-Effective Amendments to withdraw and remove from registration any unissued and unsold securities registered pursuant to the above-referenced Registration Statements.

On May 13, 2026, the Registrant entered into an Agreement and Plan of Merger (the "Merger Agreement") with Zydus Worldwide DMCC, a limited liability company incorporated under the laws of the United Arab Emirates ("Parent"), Zara Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of Parent ("Purchaser"), and, solely for purposes of Section 9.20 thereof, Zydus Pharmaceuticals (USA) Inc., a New Jersey corporation. Pursuant to the Merger Agreement, on May 18, 2026, Purchaser commenced a tender offer (the "Offer") to purchase all of the issued and outstanding shares of common stock, par value $0.0001 per share, of the Registrant (the "Shares") at a price of $23.50 per Share, payable in cash, without interest and subject to any applicable withholding of taxes. The Offer expired one minute after 11:59 p.m., Eastern Time, on June 15, 2026, and on June 16, 2026, Purchaser irrevocably accepted for payment all Shares validly tendered and not validly withdrawn pursuant to the Offer. On June 16, 2026, pursuant to the Merger Agreement and in accordance with Section 251(h) of the General Corporation Law of the State of Delaware, Purchaser merged with and into the Registrant (the "Merger"), with the Registrant continuing as the surviving corporation and a wholly-owned subsidiary of Parent.

The foregoing description of the Offer, 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 attached as [Exhibit 2.1](https://www.sec.gov/Archives/edgar/data/1808665/000110465926059856/tm2611405d26_ex2-1.htm) to the Registrant's Current Report on Form 8-K filed with the SEC on May 13, 2026.

As a result of the Merger, the Registrant has terminated all offerings of its securities pursuant to the Registration Statements. In accordance with an undertaking made by the Registrant in each of the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance that remain unsold at the termination of the offerings, the Registrant hereby removes from registration all such securities registered under the Registration Statements that remain unsold as of the date hereof and terminates the effectiveness of the Registration Statements.

**SIGNATURES**

Pursuant to the requirements of the Securities Act of 1933, as amended, and Rule 478 thereunder, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing these Post-Effective Amendments to the Registration Statements and has duly caused these Post-Effective Amendments to the Registration Statements to be signed on its behalf by the undersigned, thereunto duly authorized, in Pennington, New Jersey, on June 16, 2026.
