#### TABLE OF CONTENTS

### ABOUT OCCIDENTAL
Our principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil (which includes condensate), natural gas liquids (“NGL”) and natural gas. The chemical segment primarily manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil (which includes condensate), NGL, natural gas, carbon dioxide and power. It also optimizes its transportation and storage capacity, and invests in entities that conduct similar activities, such as Western Midstream Partners, L.P. (“WES”).

The midstream and marketing segment also includes our low carbon ventures (“OLCV”) businesses. OLCV seeks to leverage our legacy of carbon management expertise to develop carbon capture, utilization and storage projects, including the commercialization of direct air capture technology, and invests in other low-carbon technologies intended to reduce greenhouse gas emissions from our operations and strategically partner with other industries to help reduce their emissions.

Our principal executive offices are located at 5 Greenway Plaza, Suite 110, Houston, Texas 77046; our telephone number is (713) 215-7000.
