Form 4 Overview – Ribbon Communications Inc. (RBBN)
Director Shaul Shani reported two equity transactions dated 16-17 June 2025:
- Grant of 42,500 Restricted Stock Units (RSUs) on 16 Jun 2025 (Code A). These RSUs vest on 16 Jun 2026, or earlier at the 2026 annual meeting if the director is not re-elected.
- Conversion of 48,365 fully-vested RSUs into common shares on 17 Jun 2025 (Code M). The underlying RSUs were originally awarded on 17 Jun 2024 and vested in full after one year.
Following these transactions, Shani’s direct common-stock ownership increased to 153,711 shares, and he now holds 42,500 unvested RSUs that can settle one-for-one into additional common shares when vested. No open-market purchases or sales were reported, and all exercises were priced at $0, consistent with RSU settlements.
Because the filing reflects routine equity-compensation activity without any disposition of shares for cash, it is unlikely to have a material effect on Ribbon Communications’ near-term fundamentals or share-float dynamics. Nevertheless, the director’s larger share position marginally tightens equity alignment with public shareholders.
Ribbon Communications Inc. (RBBN) – Form 4 insider activity
Director Bruns H. Grayson filed a Form 4 on 18-Jun-2025 reporting two equity transactions:
- RSU grant: 42,500 restricted stock units awarded on 16-Jun-2025 (Code A). The units vest on 16-Jun-2026, or earlier at the 2026 annual meeting if the director does not stand for, or is not re-elected to, the board.
- RSU conversion: 48,365 RSUs granted on 17-Jun-2024 fully vested on 17-Jun-2025 and were converted into an equal number of common shares (Code M). No cash consideration was paid.
Following the conversion, the director’s direct beneficial ownership rose to 738,413 common shares. No shares were sold and no open-market purchases occurred; all movements stem from equity compensation. The RSU grant represents potential future dilution of 42,500 shares once vested.
