Definium (DFTX) Director Carol A. Vallone Exercises 1,086 Options

What Happened

• Carol A. Vallone, a director of Definium Therapeutics (DFTX), exercised 1,086 derivative securities (transaction code M) on 2026-09-18 at an exercise price of $35.52 per share, for a total cash outlay of $38,575. The filing also shows a simultaneous disposition of 1,086 shares at $0.00 (reported as a derivative disposition).

Key Details

• Transaction date: 2026-09-18. Exercise price: $35.52; total reported acquisition value: $38,575.
• Disposition: 1,086 shares reported disposed at $0.00 (same date and quantity).
• Shares owned after the transaction: Not specified in the provided filing excerpt.
• Filing timeliness: No late-filing indication provided in the data supplied.
• Common footnote implication: a $0.00 disposition in this context often reflects a net/cashless settlement or shares surrendered/withheld to cover exercise costs or taxes (the filing itself reports the mechanics as an exercise and a simultaneous derivative disposition).

Context

• This was an options exercise (derivative conversion). Because the same number of shares were reported as disposed at $0.00 on the same date, this does not represent an open-market sale for cash; instead it likely reflects a net settlement or withholding arrangement tied to the exercise. Such transactions are routine for exercising equity awards and do not necessarily signal a change in insider sentiment.
