Maurer Mark Lowry 4

What Happened

• Mark Lowry Maurer, Chief Risk Officer of StoneX Group Inc. (SNEX), exercised options to acquire 40,000 shares at $20.00 per share (cost = $800,000) and then sold those 40,000 shares in an open-market transaction at an average price of $124.88 per share, producing gross proceeds of $4,995,120. The filing shows a derivative disposition of 40,000 shares at $0, consistent with the exercise and immediate sale (a cashless exercise).

Context

• This pattern (exercise followed by an immediate sale) is commonly a cashless exercise: the insider exercises option(s) and sells the resulting shares, often to cover the exercise cost or taxes. The filing is factual and does not indicate the insider's motives.
