RANKIN JEAN F 4

What Happened

• Jean F. Rankin, a director of InterDigital, received an award of 906 restricted stock units (RSUs) on 2026-06-10 (reported as an acquisition at $0.00, total $0).
• A separate disposition on 2026-06-11 shows 0.864 shares cash-settled at $253.91 per share for $219 — this reflects the cash settlement of a fractional share that arose when RSUs vested.

Key Details

• Transaction dates and amounts:
  • 2026-06-10: Award/Grant (Code A) — 906 RSUs @ $0.00 (value $0).
  • 2026-06-11: Disposition to issuer (cash settlement) — 0.864 share @ $253.91 = $219.
• The RSUs were granted under the company’s 2025 Equity Incentive Plan (footnote F1).
• The 0.864-share cash payment reflects settlement of a fractional share upon vesting; the RSUs were originally granted on 2026-06-11 of the prior year and vested in full on 2026-06-11 with accrued dividend equivalents (footnote F2).
• Shares owned after the transactions are not specified in the provided data.
• Filing was submitted on 2026-06-12 for activity on 2026-06-10/11 — this appears to be timely under Form 4 reporting rules.

Context

• This filing reflects routine director compensation (an annual RSU award) and a standard cash settlement for a fractional share at vesting, not an open-market sale or purchase decision. Such awards are common for non-employee directors and do not, by themselves, indicate a change in the director’s market view.
