Key Details

• Filing date: September 10, 2026 (Form 8-K, Item 8.01).
• Shares covered: 7,095,721 shares of common stock (par value $0.0001).
• Seller: United States Department of Commerce — resale of existing shares (not a new issuance).
• Legal opinion: Paul, Weiss legal opinion filed as Exhibit 5.1 and incorporated into the S-3ASR registration statement (original S-3ASR filed January 20, 2026).

Why It Matters
This filing registers shares held by the U.S. Department of Commerce for potential resale into the public market. That can increase the number of shares available for trading (float) and potentially affect share supply and liquidity; it does not represent newly issued shares or an immediate sale. The inclusion of the legal opinion indicates the company is clearing legal matters needed to permit the resale under its existing registration statement.
