Frank Thomas AJ 4

What Happened

Frank Thomas, Executive Vice President of Interactive Brokers Group (IBKR), had 31,730 shares disposed on May 8, 2026 to satisfy tax obligations related to equity awards. The shares are recorded at $84.42 per share (closing price on the vesting date), for a total value of approximately $2,678,647. This disposition is reported under transaction code F, indicating a payment of exercise price or tax liability (i.e., share withholding), which is a routine administrative action when restricted stock units (RSUs) vest.

Key Details

• Transaction date: May 8, 2026; reported on Form 4 filed May 28, 2026 (filing appears late relative to the typical 2-business-day Form 4 deadline).
• Price used: $84.42 per share (closing price on vesting date, per footnote).
• Shares involved: 31,730 shares withheld/disposed; total value ≈ $2,678,647.
• Shares owned after transaction: Not provided in the details supplied.
• Footnotes: The amount includes (a) Class A common stock attributable to vested RSUs awarded under the amended 2007 Stock Incentive Plan and (b) unvested RSUs awarded under the Plan.
• Transaction code: F = payment of exercise price or tax liability (share withholding), not an open-market sale.

Context

Share withholding to cover taxes when RSUs vest is a common, administrative transaction and does not necessarily reflect an intentional market sell by the insider. For retail investors, such withholdings are routine and generally less informative than open-market purchases or discretionary sales. Note the Form 4 was filed about 20 days after the vesting date, which is later than standard reporting timelines and may delay public visibility into the transaction.
