Settlement of restricted stock units ("RSUs") and related dividend equivalents. Includes 16 dividend equivalents. Each RSU represents a contingent right to receive one share of the Company's common stock. On May 8, 2025, the reporting person was granted 1,570 RSUs that vested on May 6, 2026. Each dividend equivalent right is the economic equivalent of one share of the Company's common stock. The dividend equivalent rights accrued on previously awarded RSUs and vested on May 6, 2026. The RSUs represent the reporting person's annual equity award under the Company's Ninth Amended and Restated Non-Employee Director Compensation Policy. The RSUs vest on the date of the next annual meeting of the stockholders of the Company. Unvested RSUs earn dividend equivalents when dividends are declared on the Company's common stock. The number of RSUs received was calculated based on $123.02, which was the closing price of the Company's common stock on the date of grant.

4 terms

Restricted Stock Units financial

"On May 7, 2026, Ostojic received a grant of 1,503 restricted stock units (RSUs)"

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.

dividend equivalents financial

"16 dividend equivalent rights settled into 1,586 shares of common stock"

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.

Non-Employee Director Compensation Policy financial

"annual equity award under the company’s Non-Employee Director Compensation Policy"

Form 4 regulatory

"Following the Form 4 transactions, Ostojic directly holds 10,560 shares"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
