restricted common stock financial
"Represents shares withheld to satisfy Reporting Person's tax obligations in connection with the vesting of shares of restricted common stock of the Issuer."
Restricted common stock is company shares that carry limits on selling or transferring for a set period or until certain conditions are met, like time-based vesting or regulatory clearance. Think of them as shares in a locked box that gradually open; they can become freely tradable later but initially reduce the number of shares available on the market. Investors watch restricted stock because its eventual release can change a company’s share supply, affect stock price, and influence control and dilution.
Employee Stock Purchase Plan financial
"Includes 89 shares of common stock acquired under the Advanced Drainage Systems, Inc. Employee Stock Purchase Plan, exempt under Rule 16b-3(c)."
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
performance-based units financial
"Reflects grant of performance-based units, originally granted pursuant to the Issuer's 2017 Omnibus Incentive Plan, earned after the Issuer determined that certain performance goals for the performance period ended March 31, 2026 had been met."
dividend equivalents financial
"Total includes dividend equivalents in the amount of 63 shares, which dividend equivalents are settled in 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.
2017 Omnibus Incentive Plan financial
"Originally granted pursuant to the Issuer's 2017 Omnibus Incentive Plan, earned after the Issuer determined that certain performance goals had been met."
KSOP financial
"Represents current allocation under KSOP."
