[Form 4] StoneX Group Inc. Insider Trading Activity

Rhea-AI Filing Summary

StoneX Group (SNEX) – Form 4 insider transaction

On 16 June 2025, Chief Information Officer Abigail H. Perkins exercised 16,767 stock options at an exercise price of $27.58 (transaction code “M”), immediately acquiring the same number of common shares. She then sold 10,470 shares on the open market at a $86.2209 average price (transaction code “S”).

• Gross sale proceeds ≈ $0.90 million; option exercise cost ≈ $0.46 million.
• Net result: Perkins retained 6,297 additional shares, raising her direct stake from about 37,616 to 43,913 shares (+17%), plus 337 indirect shares held for her children.
• She continues to hold 241,875 unexercised options.
• No check-box was ticked indicating a Rule 10b5-1 trading plan.

The mixed transaction (partial sale after option exercise) signals both liquidity taking and increased long-term exposure. No other material events were disclosed in this filing.

Positive

• Officer retained 6,297 newly issued shares, boosting direct ownership by roughly 17%.

Negative

• Officer sold 10,470 shares for about $0.9 million, representing nearly 19% of her direct stake and executed outside a disclosed 10b5-1 plan.

Insights

Corporate Governance Analyst

TL;DR: CIO sells ~$0.9M but keeps 6k shares; net stake up 17%—signal neutral-to-slightly negative for sentiment.

The filing shows a classic exercise-and-sell pattern: the officer covered tax/liquidity by offloading 62% of exercised shares, pocketing roughly $0.9 million in proceeds while still expanding ownership by 6,297 shares. Because the sale represents about 19% of her post-exercise direct holdings and is not under a disclosed 10b5-1 plan, the market may view the cash-out negatively. However, the net increase in share count partially offsets that concern and indicates continued alignment with shareholders. With 241,875 remaining options, future dilution or additional sales are possible but not immediate. Overall impact on valuation is modest; I classify this as neutral.
