Restricted Stock Units financial

"security_title": "Restricted Stock Units""

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 equivalent rights financial

"Reflects the vesting of dividend equivalent rights that accrued on 900 restricted stock units"

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.

tax withholding obligations financial

"The reporting person disposed of shares of common stock to satisfy tax withholding obligations."

Long-Term Incentive Plan financial

"The RSUs were granted on 4/24/2025 under the Companys 2023 Long-Term Incentive Plan"

A long-term incentive plan is a company program that pays executives or employees with stock, options, or cash tied to multi-year performance goals, where the rewards become theirs only after meeting conditions over time. Think of it as a delayed bonus or retirement-style reward that aligns employees’ interests with shareholders by encouraging them to boost long-term value; investors watch these plans because they affect pay costs, share dilution and management incentives.

contingent right financial

"Each RSU represents a contingent right to receive one share of AZZ common stock."
