OCONNOR SEAN MICHAEL 4

What Happened
Sean Michael O'Connor, Executive Vice‑Chairman and Director of StoneX Group Inc. (SNEX), exercised a total of 300,000 options and immediately sold the 300,000 resulting shares across three trading dates. He exercised 140,070 shares on 2026-05-15, 87,790 shares on 2026-05-18, and 72,140 shares on 2026-05-19 at an exercise price of $13.34 per share (total cash paid ≈ $4.00M). The subsequent open‑market sales generated gross proceeds of about $33.17M (sales on 5/15 ≈ $15.45M, 5/18 ≈ $9.79M, 5/19 ≈ $7.93M). The filing shows the exercise (derivative) entries and matching sales, indicating a cashless exercise followed by immediate dispositions.

Context

• These trades were exercises of derivative awards (code M) immediately followed by open‑market sales (code S), effectively a cashless exercise/sell-to-cover or sale-for-cash strategy rather than an outright purchase indicating increased insider ownership.
• Such transactions are common for executives realizing value from vested options; they are factual disclosures and do not by themselves indicate the insider's longer‑term view.
