Harout Semerjian, Pr盲sident & CEO und Direktor von Geron Corp (GERN), erhielt am 08/07/2025 Zuteilungen von Aktienoptionen in H枚he von insgesamt 11,000,000 Optionen, die in Stammaktien ausge眉bt werden k枚nnen, mit einem Aus眉bungspreis von $1.30 je Aktie und einer Laufzeit bis zum 08/06/2035.

Februar 2026 und die verbleibenden 6,125,000 in 42 gleichen monatlichen Raten beginnend am 7. Februar 2026; eine zweite Zuteilung von 4,000,000 Optionen vestet mit 1,000,000 Aktien am 7.

Positive
  • 11,000,000 options granted to the CEO are clearly disclosed, including exercise price ($1.30) and expiration (08/06/2035).
  • Vesting schedules are detailed and explicitly conditioned on continued service, providing transparent retention terms.
Negative
  • Potential dilution upon exercise: the awards cover 11,000,000 underlying shares, which would increase share count if exercised (share鈥慶ount context not provided).

Insights

TL;DR: Large multi鈥憏ear option grant to CEO ties compensation to continued service and future performance; disclosure is routine.

The Form 4 reports two option awards totaling 11,000,000 options granted to Harout Semerjian with a $1.30 exercise price and an 08/06/2035 expiration. Vesting is explicitly conditioned on continued service with detailed tranche schedules, which aligns award realization to future employment. The direct ownership reporting and explicit vesting dates provide clear governance disclosure; the filing does not include contextual company share counts or valuation metrics, so materiality relative to outstanding equity cannot be assessed from this filing alone.

TL;DR: 11M options at $1.30 with staged vesting and long expiry are a significant executive compensation event but appear to be standard service鈥慶onditioned equity awards.

The filing specifies two option grants: 7,000,000 and 4,000,000 options, each exercisable at $1.30 and expiring on 08/06/2035. Vesting schedules provide an initial tranche and then monthly installments over 42 and 36 months respectively, explicitly conditioned on continued service. From a pay design perspective, the structure emphasizes retention and potential long鈥憈erm upside for the CEO. The filing contains no information on prior grants, total dilution, or how these awards compare to market benchmarking.
