Tax-withholding entries 1 transaction, 324 shares Summary of tax-withholding dispositions in this filing
restricted common stock financial
"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 49 shares of common stock acquired under the Advanced Drainage Systems, Inc. Employee Stock Purchase Plan"
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.
KSOP financial
"Represents current allocation under KSOP"
tax-withholding disposition financial
"transaction_action: tax-withholding disposition"
A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.
Rule 16b-3(c) regulatory
"acquired under the Advanced Drainage Systems, Inc. Employee Stock Purchase Plan, exempt under Rule 16b-3(c)"
An SEC rule that lets corporate insiders avoid automatic "short‑swing" profit recovery when they buy or sell their company’s stock under a pre‑approved, written plan that meets specific conditions. For investors, it matters because it clarifies when insider trades are treated as routine, reducing legal uncertainty and helping distinguish trades made for ordinary compensation or pre‑planned reasons from those that might signal opportunistic or timely insider advantage.
