Business Operations and Key Markets

Energy operates three businesses in three core regions: North, CEE, and South. The Exploration & Production business focuses on the exploration, development, and production of crude oil, natural gas liquids, and natural gas. The Gas business manages a comprehensive natural gas sales and logistics network, spanning from the wellhead to the end customer. This includes storage, multi-commodity trading, and the Group’s power activities. The Energy segment’s Low Carbon Business develops sustainable energy sources, including geothermal projects and renewable power solutions, such as solar and wind energy.

The Fuels business segment refines and markets crude oil and other feedstock. It operates refineries with an annual capacity of 17.8 mn t in Schwechat (Austria), Burghausen (Germany), and Petrobrazi (Romania). In these refineries, crude oil is processed into petroleum products, which are sold to commercial and private customers.

OMV has a strong position in the markets located within the areas of its supply, serving commercial customers and operating a retail business of 1,708 filling stations.

OMV holds minority stakes in various equity-accounted investments, the most significant being the 15% participation in ADNOC Refining (United Arab Emirates) with an annual refining capacity of 7.1 mn t (OMV share).

The Chemicals business segment is one of the world’s leading providers of advanced and circular polyolefin solutions and a European market leader in base chemicals and plastics recycling.

OMV Group has a production capacity, including joint ventures, of 7.0 mn t of base chemicals, 6.4 mn t of polyolefins, and 0.8 mn t of compounding. The majority of production is located in Europe, with two overseas manufacturing facilities in the United States, one in Brazil, and one in South Korea. In addition, OMV holds minority stakes in various equity-accounted investments, the most significant ones being Borouge (United Arab Emirates), a Borealis joint venture with ADNOC that operates the largest petrochemical complex in the world, and the Baystar joint venture (Pasadena, United States), which has operated an ethane cracker since 2022 and started up an additional polyethylene plant using the unique Borstar® technology in 2023.

OMV Group is pursuing various initiatives in mechanical and chemical recycling and renewable polyolefins. Borealis is building a propane dehydrogenation plant in Belgium to leverage expected growth in propylene demand in Europe. The new facility will have a production capacity of 0.7 mn t of propylene. Moreover, Borouge 4 is currently being built (Ruwais, United Arab Emirates), an ethane-based steam cracker with a total capacity of 1.5 mn t and polyolefin plants with a total capacity of 1.4 mn t using the unique Borstar® technology.

Group management, financing, and insurance activities, as well as certain service functions, are concentrated in the Corporate & Other (C&O) segment.

One of the key measures of operating performance for the Group is the Clean CCS Operating Result.

On March 3, 2025, OMV and ADNOC signed a binding agreement for the combination of their shareholdings in Borealis and Borouge into Borouge Group International. Consequently, on March 3, 2025, the Borealis Group, excluding the Borouge investments, was reclassified to “held for sale” and in addition classifies as “discontinued operations.” More information can be found in Note 4 – OMV and ADNOC to Establish a New Polyolefins Joint Venture. The result from discontinued operations remains reflected in the Clean CCS Operating Result.

The disclosure of special items is considered appropriate in order to facilitate the analysis of ordinary business performance. To reflect comparable figures, certain items affecting the result are added back or deducted. These items can be divided into four subcategories: personnel restructuring, unscheduled depreciation and write-ups, asset disposals, and other.

Furthermore, to enable effective performance management in an environment of volatile prices and comparability with peers, the CCS effect is eliminated from the accounting result. The CCS effect, also called inventory holding gains and losses, is the difference between the cost of sales calculated using the current cost of supply, and the cost of sales calculated using the weighted average method after adjusting for any changes in valuation allowances. In volatile energy markets, measuring of the costs of petroleum products sold based on historical values (e.g., weighted average cost) can have distorting effects on reported results. This performance measurement enhances the transparency of results and is commonly used in the oil industry. OMV therefore publishes this measure in addition to the Operating Result determined according to IFRS.

In 2025, special items for unscheduled depreciation and write-ups were mainly attributable to impairments of E&P assets in the Energy segment. For further details on impairments and write-ups, see Note 9 – Depreciation, Amortization, Impairments and Write-ups.

The category Other special items was mainly affected by an impairment of other financial assets in the Energy segment related to abandonment obligations, foreseen to be incurred by OMV Petrom at its own costs, following the agreed principles between OMV Petrom and the Romanian State, as well as by temporary valuation effects. For further details, see Note 20 – Financial Assets.
