Form 4 Overview � Momentus Inc. (MNTS)
Director Chris Hadfield reported a routine equity award dated 30 June 2025. The filing discloses:
- 16,294 Restricted Stock Units (RSUs) granted at $0 cost, each convertible into one Class A common share.
- The RSUs vest in full on the earlier of 30 June 2026 or the day before the 2026 Annual Meeting, contingent on continuous board service.
- After the award, Hadfield’s direct beneficial ownership totals 17,317 Class A shares.
No shares were sold and no cash changed hands; the transaction aligns director incentives with shareholder value but does not inject new capital into the company. The filing appears to be standard board compensation with no immediate balance-sheet or P&L impact.
Momentus Inc. (MNTS) � Form 4 filing dated 07/03/2025
Director Mitchel B. Kugler reported the grant of 32,588 derivative securities on 06/30/2025, split equally between:
- 16,294 Restricted Stock Units (RSUs) that convert into Class A common shares. These RSUs vest in full on the earlier of 30 June 2026 or the day before the 2026 annual meeting, contingent on continued board service.
- 16,294 Deferred RSUs whose settlement was voluntarily deferred by the director until 30 June 2030. Each Deferred RSU is economically equivalent to one Class A share.
The reported price for both grants is $0, reflecting compensation-based awards rather than open-market purchases. Following the transactions, Mr. Kugler beneficially owns the same number of derivative securities (as shown in the filing) and no change was reported for non-derivative share ownership.
Momentus Inc. (MNTS) � Form 4 insider filing. Director Victorino Mercado received an equity grant on 30 June 2025 consisting of 16,294 Restricted Stock Units (RSUs), each convertible into one share of Class A common stock at no cost. Following the grant, Mercado’s total beneficial ownership stands at 20,777 shares held directly. The RSUs will vest in full on the earlier of 30 June 2026 or the day before the 2026 annual shareholder meeting, contingent upon continued board service.
No derivative sales, option exercises, or open-market purchases were reported. The transaction is coded “A,� indicating an award rather than a market purchase, and was executed at a stated price of $0.
This filing reflects routine director compensation and does not disclose any change to corporate strategy, financial performance, or capital structure.
Amazon.com Inc. (AMZN) � Form 4 insider transaction
Douglas J. Herrington, CEO Worldwide Amazon Stores, disclosed the sale of 2,500 common shares on 01 July 2025 through a pre-arranged Rule 10b5-1 trading plan adopted on 07 Nov 2024. The three separate trades were executed at weighted-average prices of $219.17, $219.66 and $220.90, generating roughly $0.55 million in gross proceeds.
After the transactions, Herrington directly owns 514,550 shares and indirectly holds 6,592.501 shares in the Amazon 401(k) plan. The sale represents about 0.5 % of his direct ownership, indicating only a modest reduction in exposure while maintaining a sizeable equity stake that continues to align his interests with shareholders.
No derivative securities were exercised or disposed of, and there is no indication of additional insider activity in this filing.
Momentus Inc. (MNTS) � SEC Form 4 Filing
Director Linda J. Reiners was awarded 16,294 Restricted Stock Units (RSUs) on 06/30/2025. Each RSU converts into one share of Class A common stock upon vesting, increasing her direct beneficial ownership to 21,441 shares.
The RSUs vest in full on the earlier of June 30, 2026 or the day before the 2026 Annual Meeting, provided she remains on the Board. The transaction is coded “A� (award/acquisition) at a stated price of $0, indicating routine director compensation rather than an open-market purchase.
No disposals, cash transactions, or other insider activities were reported. The filing carries minimal dilution risk and does not signal additional corporate developments.
Masimo Corp, identified as a 10% beneficial owner of Neuraxis, Inc. (NRXS), filed a Form 4 disclosing a complete exit from its common-stock position on 1 July 2025.
- Common-stock sales: 531,548 shares sold at $2.25 per share (Code S); beneficial ownership after this trade: 0 shares.
- Pre-funded warrant conversion: 289,779 shares acquired via automatic warrant exercise at $0.0001 per share (Code C), immediately followed by the sale of the same 289,779 shares at $2.25 per share (Code S).
- Derivative position: The pre-funded warrant (exercise price $0.0005) was fully exercised/converted (Code M) and now shows 0 derivative securities outstanding.
Net result: Masimo liquidated a total of 821,327 shares, reducing both its direct and derivative holdings in NRXS to zero. Because Masimo previously qualified as an “insider� under Section 16 (10% owner), the disposal is considered material. The filing does not give reasons for the divestiture nor mention any concurrent corporate events at Neuraxis.
Momentus Inc. (MNTS) � Form 4 insider transaction
On 06/30/2025, Chief Technology Officer Robert E. Schwarz received an equity award of 44,809 Restricted Stock Units (RSUs), each convertible into one share of Momentus Class A common stock. The RSUs were granted at no cost (exercise price $0) and vest in three equal annual installments, contingent on Mr. Schwarz’s continued employment. Following the grant, the executive’s beneficial ownership stands at 44,809 derivative securities, reported as directly held. No open-market purchases, sales, or cash transactions were disclosed, and no non-derivative holdings were reported on the filing.
The filing is a routine compensation-related issuance intended to incentivize and retain key leadership. Given the relatively small share count versus Momentus’s total shares outstanding, the grant is unlikely to have a material dilutive impact for common shareholders.
Momentus Inc. (MNTS) Form 4 filing dated 07/03/2025 discloses that Chief Executive Officer and Director John C. Rood received 170,580 Restricted Stock Units (RSUs) on 06/30/2025. Each RSU converts into one share of Class A common stock upon vesting. The grant vests in three equal annual installments beginning on the vesting commencement date, contingent on continued employment. No common shares were bought or sold, and the RSUs were acquired at a cost basis of $0, indicating a standard equity-based compensation award rather than an open-market transaction. Following the grant, Rood beneficially owns 170,580 derivative securities (RSUs) directly. The filing contains no sales, option exercises, or non-derivative share movements, and therefore does not immediately impact the company’s share count or insider ownership percentages until the RSUs vest.
Momentus Inc. (MNTS) � Form 4 insider filing
Chief Legal Officer Jon Layman reported the grant of 127,298 Restricted Stock Units (RSUs) on 22 Apr 2025. Each RSU represents the right to receive one share of Class A common stock upon vesting. The award:
- Vests in four equal annual tranches beginning from the stated vesting commencement date, contingent on continued employment.
- Was recorded at a transaction price of $0, reflecting a compensation grant rather than an open-market purchase or sale.
- Leaves Mr. Layman with 127,298 derivative securities (RSUs) directly owned following the transaction; no non-derivative (common stock) holdings were reported.
No shares were sold or transferred, and the filing does not reflect any cash proceeds or immediate dilution. The disclosure is routine executive compensation and does not involve a 10% owner or director purchase/sale. Investors should note the potential future share issuance once the RSUs vest, which, while modest relative to Momentus� outstanding share count, will marginally increase dilution over the next four years.
