Calix (CALX) CFO Cory Sindelar Exercises Options for 27,000 Shares

What Happened

  • Cory Sindelar, Chief Financial Officer of Calix, exercised stock options on Feb 2, 2026 to acquire 27,000 shares at an exercise price of $5.05 per share, for a total cash cost of $136,350. The same filing shows a simultaneous entry for 27,000 shares reported as disposed at $0.00 (both transactions coded M for option exercise/derivative).

Key Details

  • Transaction date: 2026-02-02.
  • Acquired: 27,000 shares at $5.05 — total $136,350.
  • Disposed: 27,000 shares at $0.00 (reported as a derivative disposition).
  • Footnote: 100% of the option shares were fully vested and exercisable as of Oct 1, 2021 (per filing).
  • Shares owned after the transactions: not specified in the provided filing excerpt.
  • Filing timeliness: filing date 2026-02-03 for a 2026-02-02 transaction — no indication in the excerpt that the Form 4 was late.

Context

  • This was an option exercise (transaction code M). The paired acquisition and $0.00 disposal entries often reflect shares being surrendered or used to satisfy option terms or tax withholding, though the filing excerpt does not explicitly state the reason. Exercises are routine for vested option holders and do not by themselves indicate a bullish or bearish personal view.
