Routine director Form 144 for small RSU-vest diversification. No material impact expected. Monitor for any subsequent Form 4 filings confirming execution, but this sale is too small to signal insider concern or shift in company trajectory.
Price Chart
Executive Summary
Director Karen K. McGinnis filed a Form 144 on June 11, 2026, indicating intent to sell 6,050 common shares of Alphatec Holdings at an estimated aggregate market value of $48,460.50 (based on a $8.01 reference price). The shares originated from vesting RSUs granted on June 16, 2021. The sale appears small relative to the $1.3B market cap and the insider's likely holdings. This is a routine insider diversification move by a board member and carries no material signal for the company's operating performance or outlook.
