Common Stock financial

"The CFO used 2,600 shares of Common Stock to cover tax obligations."

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

tax-withholding disposition financial

"She used 2,600 shares of Common Stock in a 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.

Payment of exercise price or tax liability by delivering securities regulatory

"Transaction code description states Payment of exercise price or tax liability by delivering securities."

Form 4 regulatory

"The insider transaction is reported on Form 4 for Arcosa, Inc."

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.
