Form 4 shows non-cash earnout share issuance tied to prior deal.

The disclosure records an acquisition of 1,173,272 shares as earnout consideration issued to Beowulf E&D Holdings under a May 2025 purchase agreement. The trigger was the issuer’s private offering of $1,000,000,000 convertible notes on August 21, 2025, with the actual issuance dated 10/17/2025 after stockholder approval to increase authorized shares.

This is an administrative insider ownership update rather than an open-market buy or sell. It increases reported indirect holdings via affiliated entities, with additional positions listed through Riesling Power LLC, direct holdings, and Heorot Power Holdings LLC.

Impact on investors is typically neutral for a Form 4 of this nature; any market effect depends on future decisions by the holder and broader capital structure developments disclosed elsewhere.
