[S-8] Cerus Corp Employee Benefit Plan Registration

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.

Positive

• Proposed sale is immaterial at roughly 0.012 % of outstanding shares, limiting potential market impact.

Negative

• Continued insider selling (32,470 shares over three months) can be perceived negatively by some investors.

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.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Item 6. Indemnification of Directors and Officers.

As permitted by Delaware law, the Registrant’s amended and restated certificate of incorporation provides that no director will be personally liable to the Registrant or the Registrant’s stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

• for any breach of the duty of loyalty to the Registrant or the Registrant’s stockholders;

• for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

• for unlawful payment of dividends or unlawful stock repurchases or redemptions under Section 174 of the Delaware General Corporation Law; and

• the Registrant may indemnify the Registrant’s other officers, employees and agents as set forth in the Delaware General Corporation Law;

• the Registrant is required, to the fullest extent not prohibited by law, to advance expenses to the Registrant’s directors and executive officers as incurred in connection with legal proceedings against them for which they may be indemnified, against an undertaking by the indemnified party to repay such advances if it is ultimately determined that the indemnified party is not entitled to indemnification; and

• the rights conferred in the amended and restated bylaws are not exclusive.

The Company has entered into indemnification agreements with each of the Registrant’s directors and executive officers that require the Registrant to indemnify these individuals against expenses, witness fees, damages, judgments, fines and settlement amounts incurred by the director or officer in any action or proceeding, whether actual, pending or threatened, subject to certain limitations, to which any of these individuals may be made a party by reason of the fact that he or she is or was a director or an executive officer of the Registrant or is or was serving or at any time serves at the request of the Registrant as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

Item 9. Undertakings.

1. The undersigned Registrant hereby undertakes:

(a) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference herein.

(b) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

2. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
