Oil and Gas Reserve Estimation and Disclosures (unaudited) The following tables provide supplementary information in respect of the Group’s oil and gas activities. In the absence of detailed disclosure rules in this area under IFRS, the Group has elected to voluntarily disclose the data that would have been required under the ASC 932 as if it was reporting under US GAAP. To the extent that information refers to financial statements data, the information is based on the primary financial statements (IFRS financial statements). The regional structure is presented below 1: Romania and Black Sea Bulgaria, Kazakhstan and Romania Austria Austria Russia Russia North Sea Norway Middle East and Africa Iran (evaluation on hold), Kurdistan Region of Iraq, Libya, Tunisia, United Arab Emirates, Yemen, Madagascar (until 2019), Pakistan (until 2018) New Zealand and Australia Australia and New Zealand Malaysia SapuraOMV 2 1 Regions listed in the Director’s Report ‘Central and Eastern Europe’ (includes Romania and Black Sea as well as Austria) and ‘Asia-Pacific’ (includes New Zealand and Australia as well as Malaysia) are split further in this disclosure to provide the information in a more detailed manner. 2 Includes not only Malaysia but also SapuraOMV subsidiaries in New Zealand, Australia and Mexico. Acquisitions There were no major acquisitions during 2020. On January 31, 2019, OMV acquired a 50% stake of the issued share capital in SapuraOMV Upstream Sdn. Bhd. As OMV has the decision power over relevant activities, the new entity and its subsidiaries are fully consolidated. Besides future growth in daily production in Malaysian offshore gas fields, this transaction gives OMV access to exploration blocks in New Zealand, Australia and Mexico. SapuraOMV Upstream Sdn. Bdn. and its subsidiaries are depicted in the Malaysia region in the upcoming tables. On April 29, 2018 OMV acquired 20% in the offshore concession consisting of two main fields, SARB and Umm Lulu, in Abu Dhabi, as well as the associated infrastructure. Futher, a concession agreement was signed on December 19, 2018, awarding OMV with 5% interests in the Ghasha concession offshore comprising the Ghasha mega project. OMV also completed the acquisition of Shell’s Upstream business in New Zealand on December 28, 2018. Disposals There were no major disposals during 2020 and 2019. On June 28, 2018 the sale of the Upstream companies active in Pakistan was closed. Furthermore, the sale of OMV Tunisia Upstream GmbH was finalized on December 21, 2018, comprising part of OMV’s Upstream business in Tunisia. Non-controlling interest As OMV holds 51% of OMV Petrom, it is fully consolidated; figures therefore include 100% of OMV Petrom assets and results. OMV has a share of 50% in SapuraOMV and it is fully consolidated; figures therefore include 100% of SapuraOMV assets and results. Equity-accounted investments OMV holds a 10% interest in Pearl Petroleum Company Limited (Middle East and Africa region). OMV has a 24.99% interest in OJSC Severneftegazprom (Russia region). The disclosures of equity-accounted investments in below tables represent the interest of OMV in the companies. The subsequent tables may contain rounding differences.

The results of oil and gas activities should not be equated to Upstream net income since interest costs, general corporate overhead costs and other costs are not allocated. Income taxes are hypothetically calculated, based on the statutory tax rates and the effect of tax credits on investments and loss carryforwards.

Proved oil and gas reserves were estimated based on a 12-month average price, unless prices are defined by contractual arrangements. Proved developed reserves are those proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods, or in which the costs of the required equipment are relatively minor compared with the cost of a new well and through installed extraction equipment and infrastructure operational at the time of the reserves estimate. It should be reasonably certain that the required future expenditure will be made to safeguard existing equipment within the current budget. Proved undeveloped reserves are those proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion or substantial new investment is required in order to safeguard or replace ageing facilities.

Neither the effects of future pricing changes nor expected changes in technology and operating practices are considered. Future cash inflows represent the revenues received from production volumes, including cushion gas held in storage reservoirs, assuming that the future production is sold at prices used in estimating year-end quantities of proved reserves (12 months average price). Future production costs include the estimated expenditures for production of the proved reserves plus any production taxes without consideration of future inflation. Future decommissioning costs comprise the net costs associated with decommissioning wells and facilities. Future development costs include the estimated costs of development drilling and installation of production facilities. For all three categories year-end costs without consideration of inflation are assumed. Future income tax payments are calculated on the basis of the income tax rate applicable in each of the countries in which the Group operates. The present cash value results from the discounting of the future net cash flow at a discount rate of 10% per year. The standardized measure does not purport to be an estimate of the fair value of the Group’s proven reserves. An estimate of fair value would also take into account, amongst many other factors, the expected recovery of reserves in excess of proved reserves, anticipated changes in future prices and costs as well as a discount factor representative of the risks inherent in the production of oil and gas.
