Context This was an equity award (grant of RSUs), not an open-market purchase or sale. RSU grants are commonly used for compensation and retention and convert to common shares only as they vest; they therefore do not represent immediate cash value to the insider unless and until vested and sold. See the company's Form 8‑K dated June 5, 2026 for additional terms referenced in the filing.
