Rhea-AI Filing Summary

Alphatec Holdings, Inc. (ATEC) – Form 144 Notice of Proposed Sale

Insider Tyson Marshall intends to sell up to 18,092 common shares via Morgan Stanley Smith Barney on or about 5 Aug 2025. At the filing price the lot is worth $269,688.68. With 147,983,775 shares outstanding, the sale represents roughly 0.012 % of ATEC’s float.

The shares stem from restricted-stock vesting under a registered compensation plan. Marshall has already sold 14,378 shares in the prior three months for $171,952, bringing recent and proposed disposals to 32,470 shares (≈ 0.022 % of shares outstanding).

The filer certifies no undisclosed adverse information and signs the standard Rule 144 representation. No other operational or financial data are provided.

Insights

Securities Analyst

TL;DR: Small insider sale (<0.02 % of float); unlikely to pressure ATEC shares materially.

The Form 144 shows Tyson Marshall planning to dispose of 18,092 newly-vested restricted shares, valued at about $270 k. Even when combined with the 14,378 shares sold during the last quarter, the aggregate 32,470 shares equal only 0.022 % of Alphatec’s 148 m share base. Such volume is typically absorbed without meaningful price impact, suggesting a neutral signal for liquidity and valuation.

The filing offers no insight into company fundamentals; therefore, investors should treat this as routine insider diversification rather than a directional indicator. The absence of adverse-information disclaimers further supports a neutral reading.
