Context

• These were dividend reinvestments (the company issued shares in lieu of cash dividends), not open-market purchases — routine for insiders enrolled in a DRIP and generally viewed as reinvestment of income rather than a fresh cash buy signal.
• The activity increases the director's stake modestly; because DRIP shares are issued as part of routine dividend treatment and exempt under Rule 16a-11, they convey less direct investment intent than discretionary open-market purchases.
