Tenax (TENX) CEO Christopher Giordano Exercises Options

What Happened
Christopher Thomas Giordano, CEO and Director of Tenax Therapeutics (TENX), exercised stock options on July 13, 2026, acquiring a total of 8,719 shares of common stock. He paid $3.55 for 219 shares ($777) and $5.94 for 8,500 shares ($50,490), for a combined cash outlay of $51,267. The filing also shows corresponding disposition entries for the derivative instruments at $0, reflecting conversion/surrender of the options upon exercise (transaction code M = option exercise).

Key Details

  • Transaction date: July 13, 2026; Form 4 filed July 14, 2026 (appears timely).
  • Acquisitions: 219 shares @ $3.55 ($777) and 8,500 shares @ $5.94 ($50,490); total 8,719 shares, $51,267 paid in cash. (Code M = option exercise.)
  • Dispositions: 219 and 8,500 derivative units reported disposed at $0 — standard reporting when options are converted into shares.
  • Footnotes: F1 confirms the aggregate exercise price was paid in cash. F2–F6 describe various vesting schedules for the options (25% cliff then monthly vesting in some grants; some grants already vested in prior years).
  • Shares owned after the transaction: not provided in the supplied data.
  • No 10b5-1 plan, sale, or tax-withholding entry listed in the provided items.

Context

  • This was an exercise of options (not an open-market purchase or sale). The filing indicates the options were exercised and converted into shares rather than immediately sold (no sale reported).
  • Reporting of the derivative disposal at $0 is common and simply shows the option instruments were surrendered upon exercise.
  • Insider option exercises are routine but represent an acquisition of shares; investors often view purchases/exercises as more informative than routine sales, though this filing alone doesn't indicate the insider's future intentions.
