MCGINNIS KAREN K 4

What Happened

• Karen K. McGinnis, a director of Alphatec Holdings, was granted 32,012 restricted stock units (RSUs) on June 10, 2026 (acquisition reported at $0.00) and sold 6,050 shares in an open-market sale on June 11, 2026 for $8.01 per share, generating proceeds of $48,461. The RSUs represent contingent rights to receive common stock in the future.

Key Details

• Transaction dates and prices:
  • June 10, 2026: Grant of 32,012 RSUs (reported acquisition at $0.00).
  • June 11, 2026: Sale of 6,050 shares at $8.01 each for $48,461 total.
• Shares owned after the transactions: Not specified in the Form 4 filing.
• Notable footnotes:
  • The 32,012 RSUs vest on the earlier of the next annual meeting of stockholders or the reporting person's death/resignation; if death/resignation occurs, vesting is pro rata based on days served (Footnote F1).
  • The June 11 sale was executed under a Rule 10b5-1 trading plan adopted November 21, 2025 to satisfy tax withholding obligations arising from RSU vesting (Footnote F2).
• Filing timeliness: The Form 4 was filed June 12, 2026 for transactions on June 10–11, 2026; the filing appears timely.

Context

• The RSU grant is a compensation award (no cash purchase) and does not necessarily reflect an immediate change in market exposure until the units vest and convert to shares.
• The open-market sale was handled under a pre-established 10b5-1 plan to cover tax withholding from RSU vesting, which is a routine, non-discretionary mechanism many insiders use; such sales are generally considered administrative rather than a direct statement of sentiment.
