  General Fusion's Lawson Machine 26 (LM26) achieved compressional plasma heating to 0.72 keV (8.4 million degrees Celsius), representing a more than 3x increase in electron temperature.

• Validation of Core Technology

  The LM26 machine demonstrated significant increases in plasma density and magnetic field (10x starting values), maintained plasma stability, and showed no significant contamination, validating its Magnetized Target Fusion approach.

• Progress Towards Key Milestone

  These results represent significant progress toward the company's next major targeted milestone of 1 keV electron temperature, with a technical paper submitted for peer review.

• Strategic Timing Ahead of Merger Vote

  This positive technical update comes just before the July 6, 2026, shareholder meeting for Spring Valley Acquisition Corp. III to approve the business combination with General Fusion.

General Fusion, the target of Spring Valley Acquisition Corp. III's SPAC merger, announced a significant technical breakthrough in its Magnetized Target Fusion (MTF) technology. The company's LM26 machine achieved compressional plasma heating to 0.72 keV (8.4 million degrees Celsius), a more than threefold increase, along with significant increases in plasma density and magnetic field, and demonstrated plasma stability. This validation of core technology is critical for a pre-revenue fusion energy company and comes just weeks before the shareholder vote on the proposed business combination, potentially boosting investor confidence and influencing redemption rates.
