Amended and Restated 2015 Long-Term Incentive Plan financial

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

dividend reinvestment financial

"Includes 258 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.

tax withholding obligations financial

"Represents shares of common stock withheld to satisfy tax withholding obligations."

tax-withholding disposition financial

"transaction_action: "tax-withholding disposition" for 913 shares of Common Stock."

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.

"transaction_code_description: "Grant, award, or other acquisition" for 4,149 shares."
