Context

• The RSU grant is a typical equity award to align management/directors with shareholders; these units convert to shares upon vesting (here, one year after grant).
• The open‑market purchase is a direct buy of common shares; purchases by insiders are often considered more informative than routine sales, though filings do not state the insider’s motive.
