Compensation-related stock grant, not an open-market trade.

Christopher Seay Peacock received 669 shares of restricted common stock in a grant categorized as a “grant, award, or other acquisition.” The shares were issued at a stated price of $0.00 per share, indicating a compensation award rather than a purchase.

The restricted stock vests in three equal annual installments starting on the grant anniversary, so full ownership depends on continued service and award conditions.
