Item 4 is hereby amended to add the following: Termination of Rights Agreement On June 5, 2026, the Issuer and Computershare Trust Company, N.A., as rights agent (the "Rights Agent"), executed Amendment No. 1 (the "Amendment") to the Rights Agreement, dated as of February 2, 2026, by and between the Issuer and the Rights Agent (as amended, the "Rights Agreement"). The Amendment accelerates the expiration date of the Rights Agreement to the earlier of June 8, 2026, and the Redemption Date (as defined in the Rights Agreement). At the time of the termination of the Rights Agreement, all of the Rights that were previously distributed to holders of the Issuer's issued and outstanding common stock pursuant to the Rights Agreement will expire. In deciding to accelerate the expiration date to June 8, 2026, the Issuer's Board of Directors determined that an active Rights Agreement is no longer needed to protect stockholder value at this time. Joint Mining Agreement On April 27, 2026, the Issuer entered into a Joint Mining Agreement with Big Digital Energy, LLC ("BDE"), (the "Colocation Agreement"). Through the Colocation Agreement, Management desires to bring real revenue into the Issuer in the short term while pursuing its goal to move its operations away from Bitcoin mining towards selectively monetizing excess capacity where economically prudent and aligned with shareholder value creation. The Issuer's core strategy is to optimize the utilization of each megawatt by deploying it toward the highest-value applications, with current priority given to future expansion into AI and high-performance computing ("HPC") data center developments. BDE is deemed an affiliate of the Issuer because it is owned and/or controlled by the Reporting Persons. Entities affiliated with the Reporting Persons hold 60%, 20%, and 20% ownership interests, respectively, in BDE. Under the terms of the Colocation Agreement, BDE will purchase and deliver approximately 25,000 s19xp mining computers, and the Issuer will provide BDE with approximately 75MW of computing capacity at its facility in Midland, PA. The Parties will operate under a 50%/50% profit-sharing structure, pursuant to which the Issuer will receive all cash net proceeds from the mining operations. The cash revenue will be used for general corporate purposes and asset purchases to ensure the Issuer's use of all available power across its facility locations. As its share of the profit-sharing structure, BDE will receive monthly grants consisting of a combination of (i) shares of the Issuer's common stock, where the number of shares will equal 20% of its share of the monthly cash net proceeds divided by 30-day volume weighted average price of the Issuer's common stock ("VWAP") on the grant date, and (ii) pre-funded warrants to purchase the Issuer's common stock, where the number of underlying shares will equal 80% of its share of the monthly cash net proceeds divided by $20. The pre-funded warrants allowed BDE to purchase the Issuer's common stock at an exercise price of $20 per share and have a five-year term.
