restricted stock unit financial

"Represents a restricted stock unit ("RSU") award."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

RSU financial

"Represents a restricted stock unit ("RSU") award."

Restricted stock units (RSUs) are a form of company shares given to employees as part of their compensation, usually with certain restrictions or conditions, such as remaining with the company for a set period. When these restrictions lift, employees receive actual shares that they can sell or hold. For investors, RSUs can impact a company's stock supply and reflect the company's commitment to attracting and retaining talent.

tax liability financial

"withheld by the Issuer to cover the tax liability upon the vesting"

withheld financial

"These shares were withheld by the Issuer to cover the tax liability"

Chief Executive Officer financial

"officer_title": "Chief Executive Officer""

A chief executive officer (CEO) is the top leader of a company, responsible for making major decisions, setting goals, and guiding the organization’s overall direction. Think of the CEO as the captain of a ship, steering it toward success. Investors pay close attention to the CEO because their leadership and strategy can significantly influence the company's performance and future growth.

The 500,221 restricted stock units granted to ACV Auctions’ CEO vest in twelve substantially equal quarterly installments starting July 1, 2026. Vesting requires his continuous service through each vesting date, spreading the award’s benefit over several years as he remains with the company.

Were any ACVA shares sold by the CEO in this filing?

No discretionary open-market sales were reported. Instead, 33,405 shares of ACV Auctions Common Stock were withheld at $4.27 per share to cover tax liabilities from a prior RSU vesting, which the filing clarifies does not represent a voluntary sale by the CEO.

How many ACVA shares does the CEO own after these Form 4 transactions?

For the tax-withholding transactions on April 1, 2026, ACV Auctions used a price of $4.27 per share. At that price, 33,405 shares of Common Stock were withheld to satisfy the CEO’s tax obligations arising from the vesting of a previously granted RSU award.

Why were ACVA shares withheld in the Form 4 instead of being sold in the market?

The filing states that the 33,405 ACV Auctions shares were withheld by the issuer to cover tax liability from a prior RSU vesting. This mechanism settles taxes directly with shares, avoiding an open-market sale and not reflecting a discretionary trading decision by the CEO.
