Insights

Equity compensation analyst

CEO received stock award; shares withheld only for taxes.

Arcosa’s President & CEO Antonio Carrillo was granted 72,142 common shares as equity compensation. This aligns with typical long-term incentive structures that tie leadership rewards to company share performance rather than representing an open-market purchase.

On the same day, 37,157 shares were withheld at $105.68 per share to cover tax liabilities, a non-market disposition. After these transactions, Carrillo directly holds 525,601 shares. The activity appears routine and compensation-driven, not a change in his discretionary investment stance.

What is the significance of the tax withholding in the Arcosa (ACA) Form 4?

The tax withholding reflects 37,157 shares surrendered at $105.68 per share to cover tax obligations on the stock award. Such F-code transactions are non-market dispositions, meaning they do not represent an open-market sale decision by the executive.

Does the Arcosa (ACA) Form 4 suggest a change in the CEO’s confidence?

The filing primarily shows routine equity compensation and tax withholding, not discretionary trading. A grant of 72,142 shares and related tax withholding are standard for executive pay programs and do not, by themselves, clearly indicate a change in the CEO’s sentiment.
