stock units financial

"The shares indicated constitute units that settle solely in the common stock"

Stock units are individual pieces of ownership in a company, like slices of a pie that together make up the whole business. They matter to investors because each unit represents a claim on the company’s assets, profits and sometimes voting power, and changes in the number or value of these units affect ownership percentages, potential dividends and share dilution — all of which influence an investment’s worth.

common stock financial

"settle solely in the common stock of American Water Works Company, Inc."

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.
