Class C Common Stock financial

"security_title: "Class C Common Stock""

A class C common stock is a type of company share that usually represents ownership but often carries limited or no voting power compared with other share classes. For investors, that matters because it can affect influence over company decisions and sometimes the stock’s price or dividend priority — think of it as owning a ticket to the same event but in a section with less say in how the event is run.

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.

grant/award acquisition financial

"transaction_action: "grant/award acquisition""

Employee Stock Purchase Plan financial

"Includes shares purchased through the Under Armour, 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.
