Form 4 overview: On 07/31/2025 System1 (SST) granted Director Moujan Kazerani 15,000 restricted stock units (RSUs) under the 2022 Incentive Award Plan. Each RSU converts 1-for-1 into Class A common stock.
Vesting schedule: The award vests in four equal tranches on 15 Sep 2025, 15 Dec 2025, 15 Mar 2026 and 15 Jun 2026, conditional on continued Board service. The grant was reported at $0 since no cash changed hands.
Post-transaction holdings: Kazerani now beneficially owns 40,292 Class A shares (including 15,000 unvested RSUs), all held directly. No shares were sold or otherwise disposed of.
Context: The company completed a 1-for-10 reverse split on 11 Jun 2025; share counts in this filing reflect the adjusted capital structure. The incremental dilution from the RSU award is immaterial but further aligns a non-executive director with shareholder interests.

On 31 July 2025, director John Civantos was granted 15,000 restricted stock units (RSUs) under the company’s 2022 Incentive Award Plan. Each RSU converts into one share of Class A common stock.

The disclosure reflects routine director compensation and does not indicate any change in the issuer’s operating outlook or capital structure.
System1, Inc. (SST) – Form 4 filed 4 Aug 2025
Director Caroline Horn reported the award of 15,000 restricted stock units (RSUs) on 31 Jul 2025 under the 2022 Incentive Award Plan. The RSUs convert into Class A common stock on a 1-for-1 basis and vest in four equal quarterly installments on 15 Sep 2025, 15 Dec 2025, 15 Mar 2026 and 15 Jun 2026, contingent on her continued board service. No cash was paid (grant price $0).
Following the grant, Horn’s beneficial ownership rose to 37,418 Class A shares, which includes the 15,000 unvested RSUs. The share count reflects System1’s 1-for-10 reverse stock split completed 11 Jun 2025.
The filing signals director retention and modestly strengthens insider alignment, but the incremental issuance is immaterial relative to System1’s total outstanding shares and has no immediate earnings impact.
System1, Inc. (SST) – Form 4 insider filing: President, COO and Director Charles Ursini reported the grant of 337,500 Class A RSUs on 29-Jul-2025. The award was made at $0 cost as part of his ongoing employment agreement.
The RSUs vest one-third on 15-Jul-2026; the remaining two-thirds vest in eight equal quarterly tranches thereafter, subject to continued employment. Following the grant, Ursini’s total beneficial ownership is 367,500 shares, which includes the newly issued unvested RSUs.
The filing also notes that the share count reflects System1’s 1-for-10 reverse split completed on 11-Jun-2025. No shares were sold or disposed; the transaction increases insider alignment but adds potential future dilution once the RSUs settle.
System1, Inc. (SST) – Form 4, filed 30-Jul-2025
Chief Financial Officer Tridivesh Kidambi reported two equity transactions dated 28-29 Jul-2025:

SARs vest in 25% tranches as System1 achieves trailing-12-month Adjusted EBITDA milestones of $50 m, $55 m, $60 m and $65 m.
Post-transaction holdings: 121,124 Class A shares (including 56,276 unvested RSUs) and 72,000 SARs, all held directly. Share totals reflect the company’s 1-for-10 reverse split completed 11-Jun-2025.
