Item 2.01.

Completion of Acquisition or Disposition of Assets.

As previously disclosed, on April 1, 2024, Eiger BioPharmaceuticals, Inc. (the “Company”) and its direct subsidiaries filed voluntary petitions for relief (the “Bankruptcy Petitions”) under chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Northern District of Texas (the “Bankruptcy Court”) under the caption In re Eiger BioPharmaceuticals, Inc., et al, Case No. 24-80040 (the “Chapter 11 Cases”).

On April 17, 2024, following the completion of the auction held as part of the Company’s court-supervised sale process under Section 363 of the Bankruptcy Code for the sale of the Company’s Zokinvy asset, Sentynl Therapeutics, Inc. (“Sentynl”) was designated the winning bidder with a final bid during the auction of a base price in the amount of $46.1 million less a credit in the amount of $0.9 million for the termination fee resulting in a net base price in the amount of $45.2 million, subject to certain purchase price adjustments, including a reduction of $100,000 per diem if the sale closed after April 24, 2024. At a hearing held on April 23, 2024, the Bankruptcy Court approved the sale of the Company’s Zokinvy asset to Sentynl. The sale closed on May 3, 2024.

Under the terms of the acquisition, Sentynl acquired global rights to Zokinvy and will be responsible for its manufacture and commercialization.


Item 8.01.

Completion of Acquisition or Disposition of Assets.

During the pendency of the Chapter 11 Cases, in lieu of filing annual reports on Form 10-K and quarterly reports on Form 10-Q under Section 13(a) of the Securities Exchange Act of 1934, as amended, the Company expects to file with the Securities and Exchange Commission, under cover of current reports on Form 8-K, copies of the monthly financial reports required to be filed with the Bankruptcy Court pursuant to rule 2015 of the Federal Rules of Bankruptcy Procedure, as well as any other material information concerning developments in its bankruptcy proceedings.

Cautionary Statements Regarding Trading in the Company’s Securities

The Company’s securityholders are cautioned that trading in the Company’s securities during the pendency of the Chapter 11 Cases is highly speculative and poses substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual recovery, if any, by holders thereof in the Chapter 11 Cases. Accordingly, the Company urges extreme caution with respect to existing and future investments in its securities. In particular, the Company expects that its securityholders could experience a significant or complete loss on their investment, depending on the outcome of the Chapter 11 Cases.


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.
