Pursuant to its terms, the Wulf Resignation Notice expired on January 31, 2026 because the conditions to the effectiveness of Ms. Wulf’s resignation were not satisfied. Therefore, Ms. Wulf has not resigned from the Board and continues to serve as a director of the Company. Rick Sterling’s notice of resignation (the “ Sterling Resignation Notice”), which was also submitted on October 28, 2025, as previously disclosed in the Initial 8-K, remains in effect, subject to the satisfaction of certain conditions set forth in the Sterling Resignation Notice. The resignation notices referenced above were not submitted as the result of any disagreement with the Company on any matter relating to its operations, policies, or practices. Except as expressly set forth herein, this Current Report on Form 8-K/A does not amend the Initial 8-K in any way and does not modify or update any other disclosures contained in the Initial 8-K. This Current Report on Form 8-K/A supplements the Initial 8-K and should be read in conjunction with the Initial 8-K. ‎ 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.
