• Merger Deadline Extended

  To prevent an imminent termination of the Business Combination Agreement, the Second Amendment pushes the Outside Date from August 6, 2026 to December 31, 2026.

• Flexible Extension Mechanism

  Should the SPAC secure an extension of its own business combination deadline, either party can further extend the Outside Date to the shorter of the SPAC extension period or a mutually agreed period.

• Going Concern Context

  The extension arrives as SilverBox Corp IV faces a going concern warning and low cash, making the merger critical for survival.

• Shareholder Vote on August 11

  A shareholder meeting is scheduled for August 11, 2026 to vote on extending the SPAC's liquidation deadline, which could trigger further merger deadline extensions.

The Second Amendment moves the merger Outside Date from August 6, 2026 to December 31, 2026, buying more time to close the Parataxis deal. This follows a recent proxy supplement that extended the SPAC's own liquidation deadline to April 2027, but the merger agreement itself still needed an extension. The amendment also ties further extensions to any future SPAC deadline moves, keeping the merger timeline flexible. With the stock near its 52-week high and a going concern warning in the background, this extension is critical to avoid a deal collapse.
