• Stockholder approval occurred at the Annual Meeting on June 9, 2026.
• Certificate of Amendment filed with the Delaware Secretary of State and effective on filing (Exhibit 3.1 filed with the 8-K).

Why It Matters

• The amendment raises the number of shares the company is legally permitted to issue.

This filing is a corporate charter change and does not itself issue new shares or disclose any immediate financing, compensation, or transaction plans.
