Restricted Stock Units financial

"Each Restricted Stock Unit represents a contingent right to receive one share of Vulcan Common Stock."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Omnibus Long-Term Incentive Plan financial

"Annual stock grant made to the reporting person under the Vulcan Materials Company 2025 Omnibus Long-Term Incentive Plan."

cliff vest financial

"Restricted Stock Units cliff vest on the specified date."

A cliff vest is a schedule for stock options or restricted shares where no ownership rights are earned until a fixed date, after which a set portion becomes fully owned all at once — like a probation period that suddenly unlocks pay. Investors watch cliff vests because they influence when insiders can sell shares, affect staff retention and dilution timing, and help predict short-term changes in a company’s shareholder makeup.

Board of Directors financial

"delivered to the reporting person when the reporting person ceases to hold office as a member of the Board of Directors of Vulcan Materials Company."

The Board of Directors is a group of people chosen by a company's owners to help make big decisions and oversee how the company is run. They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.
