Marmurek Eric S 4

What Happened

• Eric S. Marmurek, Chief Financial Officer of Ribbon Communications (RBBN), received three equity awards on June 15, 2026 totaling 300,000 shares (150,000 + 90,000 + 60,000). Each grant is reported as a derivative award at $0.00 per share (award/grant code A).
• These awards consist of restricted stock units (RSUs) and performance stock units (PSUs) that convert to common stock on a one-for-one basis; they are not immediate cash or open-market purchases/sales.

Key Details

• Transaction date: June 15, 2026; Form 4 filed June 17, 2026 (filing appears timely).
• Reported grants: 150,000; 90,000; 60,000 shares (total 300,000). Price reported: $0.00 (derivative awards).
• Shares owned after transaction: Not specified in the Form 4 filing.
• Vesting and performance notes:
  • RSUs vest one-third on June 15, 2027, with the remaining two-thirds vesting in four equal semi‑annual installments through June 15, 2029. (Footnote F2)
  • One PSU tranche vests April 15, 2029 and is earned based on annual goals for the three fiscal years prior to vesting; payout may be 0%–100% of target. (Footnote F3)
  • Another PSU tranche vests April 15, 2029 and is earned based on relative total shareholder return (TSR) vs. a peer group; payout may be 0%–125% of target. (Footnote F4)
• These are standard equity compensation grants (code A); no sale, purchase, exercise, or tax-withholding sale is reported.

Context

• Awards like RSUs and PSUs represent potential future ownership contingent on continued service and/or performance; they do not reflect immediate cash proceeds or market selling/buying activity.
• PSUs are performance-contingent — the final number of shares issued can be lower or higher than the target amounts depending on achievement of the stated metrics.
