KRITZMACHER JOHN A 4

What Happened

• John A. Kritzmacher, a director of InterDigital, was reported as receiving an award of 906 restricted stock units (RSUs) (reported 2026-06-10, $0.00 grant price). Following vesting, 0.864 fractional shares were cash‑settled to the issuer on 2026-06-11 for $253.91 per share, totaling $219.
• The grant is a compensatory award (not a market purchase); the small cash settlement is a routine disposition of a fractional share and not an open‑market sale.

• Footnotes: F1 — Annual RSU award under the company’s 2025 Equity Incentive Plan for non‑management directors. F2 — The 0.864 share disposal reflects cash settlement of a fractional share from RSUs granted 6/11/2025 that vested 6/11/2026, including accrued dividend equivalents.

Context

• RSU awards to non‑employee directors are routine compensation and do not necessarily signal a buy/sell view by the director. The fractional‑share cash settlement is common practice to avoid issuing fractional shares and involved only $219, so it is immaterial in size.
