dividend reinvestment plan financial

"Includes 119 shares acquired through dividend reinvestment plan as of April 28, 2026."

A dividend reinvestment plan lets shareholders automatically use cash dividends to buy more shares of the same company instead of receiving the money. It matters to investors because it turns regular payouts into a steady way to grow ownership and take advantage of compound returns—like having your savings automatically buy additional slices of a pie over time—while often reducing transaction costs and smoothing purchase timing.

Common Stock financial

"security_title: Common Stock"

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.
