FAQ

What insider transaction did GPC executive Alain Masse report?

Alain Masse reported that 403 shares of Genuine Parts common stock were withheld on August 1, 2026 at $128.52 per share. The disposition was coded “F,” indicating shares were used to cover an exercise price or tax liability rather than sold on the open market.

How many Genuine Parts (GPC) shares does Alain Masse own after this Form 4?

After the withholding, Alain Masse directly holds 24,850 shares of Genuine Parts common stock. A footnote explains this ending balance was increased by 32 shares to reflect additional shares received through dividend accrual.

Was the GPC Form 4 transaction by Alain Masse an open-market sale?

No. The Form 4 uses code F, described as “Payment of exercise price or tax liability by delivering or withholding securities.” This indicates 403 shares were withheld to meet obligations, not sold in a discretionary open-market transaction.

At what price were Alain Masse’s GPC shares valued for the withholding?

The 403 Genuine Parts shares were valued at a per-share price of $128.52 for this transaction. This price is used to determine the value of the shares applied toward the exercise price or associated tax liability.

Was Alain Masse’s GPC transaction identified as under a Rule 10b5-1 plan?

The Form 4’s Rule 10b5-1 checkbox is not checked, so the transaction is not affirmatively reported as made under a Rule 10b5-1 trading plan. The filing instead characterizes it as a tax or exercise-price related share withholding.

What does the dividend accrual footnote mean in Alain Masse’s GPC filing?

A footnote states Masse’s ending balance was increased by 32 shares to account for dividend accrual. This means additional Genuine Parts shares were credited to him due to dividends, and these are included in the 24,850-share post-transaction holding.
