Valuations for Oil and Gas Company Exploration and Production (E&P) is highly specialized. Significant scientific and technical issues are involved in the evaluation of information, due diligence, and nomenclature. Activities within the upstream sector include searching for potential underground or underwater oil and gas fields, drilling exploratory wells, and drilling and operating wells that recover and bring to the surface crude oil, natural gas and related liquids. E&P firms represent the “upstream” aspect of the energy industry. Pipeline and marketing firms are known as “midstream” companies, and refiners and petrochemical companies are considered “downstream” participants.
The primary assets of an E&P company are its oil and gas reserves, that is, hydrocarbons below the surface that have not yet been produced and are economically viable to extract. E&P firms are unique in that their primary asset base is depleting and therefore must be continually replaced through either drilling activities or acquisition. Ownership interests related to reserves can be held in a variety of forms including working interests, royalty (or mineral) interests, and overriding royalty interests.
When analyzing historical financial statements, it is useful to include historical production volumes as well as the average hydrocarbon prices received for the periods in question. Since hydrocarbons are a commodity, the physical volumes indicate whether the company is producing more or less, regardless of revenue increases resulting from price increases. Rather than EBITDA (earnings before depreciation, interest, taxes, and depreciation and amortization), analysts usually consider EBITDAX a primary pricing metric for E&P companies. EBITDAX represents EBITDA before exploration costs for successful efforts companies.
A forward or current year indication of reserves, production, and EBIDAX should be utilized because of the frequency of reserve acquisitions and divestitures among the publicly traded E&P companies that could distort valuation indications.
