Ribbon (RBBN) COO Sam Bucci Receives 500,000 Equity Awards
What Happened Sam Bucci, Chief Operating Officer of Ribbon Communications (RBBN), received a total of 500,000 derivative equity awards on June 15, 2026, reported as three grants of 250,000, 150,000 and 100,000 units. Each award was reported at $0.00 because these are restricted stock units (RSUs) and performance stock units (PSUs) — not open-market purchases or sales — and will convert one-for-one into common stock upon vesting.
Key Details
- Transaction date: 2026-06-15; filing date: 2026-06-17 (Form 4, accession 0001708055-26-000058) — filing appears timely.

- Units granted: 250,000 + 150,000 + 100,000 = 500,000 total units.

- Important footnotes from the filing:
- RSUs and PSUs convert to common stock on a one-for-one basis (F1).
- RSU vesting: 1/3 on June 15, 2027; remaining 2/3 in four equal semi-annual installments through June 15, 2029 (F2).
- One PSU tranche vests April 15, 2029 and pays 0–100% of target based on annual goals set by the Compensation Committee (F3).
- Another PSU tranche vests April 15, 2029 and pays 0–125% of target based on relative total shareholder return vs. a peer group (F4).
Context These awards are compensation grants that will convert to common shares only if and when they vest (time-based RSUs and performance-based PSUs). PSUs may pay out anywhere from zero up to the indicated caps depending on performance, so the ultimate number of shares issued could be less than or greater than the target amounts reported. Because this is a grant (not a market buy or sale), it reflects executive compensation rather than an immediate insider purchase or liquidation.
