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.

Amended and Restated 2015 Long-Term Incentive Plan financial

"Award of common stock units under Occidental Petroleum Corporation's Amended and Restated 2015 Long-Term Incentive Plan."

dividend reinvestment financial

"Includes 58 shares acquired between July 2025 and April 2026 through dividend reinvestment."

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.
