‌Highlights

Segment developments balanced by diversified business model - results for the first quarter in line with expectations

• Positive development - supported by investment-related organic growth - recorded by the regulated Networks Segment and in South East Europe

• Substantial price- and volume-related earnings decline in the Generation Segment

• Normalisation of earnings in the energy distribution business slowed by the creation of a provision in connection with the new, legally required social tariff

• Lower earnings contribution from the equity accounted subsidiaries RAG and Burgenland Energie

• Revenue +3.3%, EBITDA -2.2%, Group net result +9.8%

  Energy sector framework conditions

• Temperature-related energy demand in Austria significantly above the long-term average and previous year; slight increase in the heating degree total in North Macedonia and significantly milder weather in Bulgaria

• Generation coefficients for wind and water - with the exception of water flows in North Macedonia -clearly below the long-term average and previous year in all markets

• Average spot wholesale prices for base load electricity slightly lower than the previous year

  Continued progress in the expansion of

  wind power, photovoltaics and battery storage

• Installed wind power capacity rises to 561 MW at the end of December 2025 (30 September 2025: 532 MW);

  expansion goal: 770 MW by 2030

• Installed photovoltaic capacity totals 133 MWp at the end of December 2025 (30 September 2025: 120 MWp);

  expansion goal: 300 MWp by 2030

• Installed battery storage capacity equals 12 MW at the end of December 2025 (30 September 2025: 8 MW);

  expansion goal: 300 MW by 2030

  Investment programme with approximately EUR 1bn annually up to 2030

• Thereof roughly four fifths in Lower Austria with focal points on the network infrastructure, renewable generation, battery storage, e-charging infrastructure and drinking water supplies

• Transformation of the energy system as a stated growth perspective in accordance with EVN's Strategy 2030

  Closing for the sale of the international project business expected by the end of March 2026

• The Environment Segment is no longer reported separately (see the explanation of the changed segment structure on page 10)

  Long-term financial ambition by 2030

• The planned implementation of our Strategy 2030 in connection with an annual investment volume of roughly EUR 1bn will drive organic growth in all segments. On this basis, our target for EBITDA in the 2029/30 financial year ranges from approximately EUR 1.1bn to EUR 1.2bn.

  Outlook and dividend policy for the current financial year confirmed

• EVN expects EBITDA and Group net result for the current 2025/26 financial year roughly at the prior year level -under the assumption of a stable regulatory and energy policy environment.

• Group net result is expected to range from approximately EUR 430m to EUR 480m.

• The dividend for the financial years beginning with 2025/26 is planned to equal at least EUR 0.90 per share. In the following years up to 2029/30, the dividend should increase to at least EUR 1.10 per share to reach a payout ratio of roughly 40%.

• Revenue: +3.3% to EUR 830.7m

• EBITDA: -2.2% to EUR 247.4m

• EBIT: -7.8% to EUR 153.2m

• Group net result: +9.8% to EUR 126.9m

Revenue recorded by the EVN Group rose by 3.3% to

EUR 830.7m in the first quarter of 2025/26, above all due to regulatory price effects in the distribution network companies in Lower Austria and Bulgaria. This positive development was contrasted by a price- and volume-related decline in revenues from renewable generation. In addition, the contract for the provision of reserve capacity from the Theiss power plant was not extended by the transmission network operator APG and therefore expired on 30 September 2025. That also contributed to the reduction of revenue from thermal electricity generation.

Personnel expenses were 3.8% higher at EUR 119.8m. The main reasons included adjustments required by collective bargaining agreements and a slight increase in the average workforce to 7,719 (previous year: 7,695 employees).

Other operating expenses rose by 4.9% to EUR 43.5m due to a year-on-year increase in receivables write-offs.

The share of results from equity accounted investees with operational nature fell by more than half to EUR 23.2m (previous year: EUR 47.1m). The decline resulted from lower earnings contributions, especially from RAG, Burgenland Energie and Verbund Innkraftwerke. The targeted continuation of earnings normalisation at the supply company EVN KG was slowed by the creation of a provision in connection with the new, legally required social tariff.

Other operating income in the comparative period included insurance compensation for damages which resulted from the flooding in Lower Austria during September 2024. This was reflected in a decline of 24.2% to EUR 43.7m in the reporting period. Other operating income for the first quarter of 2025/26 also includes a positive non-recurring effect from the acquisition of a company.

The cost of electricity purchases from third parties and primary energy expenses rose by 1.5% to EUR 424.0m, above all due to higher upstream network costs at Netz Niederösterreich and an increase in procurement costs at EVN Wärme. Contrasting factors included a decline in natural gas procurement volumes and costs as well as lower procurement costs for generation.

Based on these developments, EBITDA declined by 2.2% year-on-year to EUR 247.4m.

The high volume of investments led to an increase of 8.4% in scheduled depreciation and amortisation to EUR 94.2m. EBIT as 7.8% lower year-on-year at EUR 153.2m.

Financial results, which were negatively influenced in the comparative period by a foreign exchange effect related to the deconsolidation of the two sludge-fired combined heat and power plants in Moscow, improved to EUR -11.1m in the first quarter of 2025/26 (previous year: EUR -16.9m).

The result before income tax declined by 4.8% to EUR 142.1m. After the deduction of EUR 14.4m in income tax expense (previous year: EUR 27.7m), which was reduced by the reversal of a tax provision, and the earnings attributable to non-controlling interests, Group net result for the period equalled EUR 126.9m. That represents a year-on-year increase of 9.8%. The earnings from discontinued operations (reporting under IFRS 5 of the available-for-sale parts of the international project business) which are included in Group net result amounted to EUR 3.3m (previous year: EUR 5.1m).

Statement of financial position

EVN's balance sheet total equalled EUR 11,233.8m as of

31 December 2025 and was 1.8% over the level on 30 Sep-

tember 2025.

Property, plant and equipment and intangible assets increased during the first quarter of 2025/26 as a result of the ongoing investment activity. The carrying amount of equity accounted investments was also higher as of 31 December 2025, while

the positive development of the Verbund share led to a slight increase in other investments. The Verbund share closed the reporting period at EUR 62.00, compared with EUR 61.90 as of 30 September 2025. In total, non-current assets rose by 1.2% to EUR 9,739.0m.

Current assets rose by 5.9% to EUR 1,494.9m as of

31 December 2025. Seasonal and closing date effects led to an increase in trade receivables at Netz Niederösterreich, EVN Wärme and the sales companies in South East Europe.

In contrast, the investments in cash funds declined in comparison to 30 September 2025. Current assets also include the assets in the available-for-sale parts of the international project business, which were reclassified according to IFRS 5 and have been reported under discontinued operations since 30 September 2025.

EVN Letter to Shareholders 1st Quarter 2025 / 26 Key Figures Highlights Interim management report Segment reporting Consolidated interim report

‌EVN's equity after the first quarter of 2025/26 amounted to EUR 6,790.5m, exceeding the value as of 30 September 2025 due to the result recorded in the period. The first quarter state-ment of financial position does not include the dividend of EUR 0.90 per share for the 2024/25 financial year,

which will be proposed to the 97th Annual General Meeting on 25 February 2026 and is planned for distribution on

5 March 2026. The equity ratio remained unchanged at 60.4% as of 31 December 2025 (30 September 2025: 60.4%).

Non-current liabilities rose by a slight 1.1% over the level on 30 September 2025 to EUR 3,181.7m as of 31 Decem-

ber 2025. This development reflected the high investment activity and the resulting increase in construction and investment subsidies.

Current liabilities increased by 2.9% over the level at year-end 2024/25 to EUR 1,261.6m at the end of the reporting period. In addition to a higher balance of liabilities to an equity accounted investee which are reported under other current liabilities, this position also includes a new short-term bank liability. A contrasting factor involved the reversal of a provision for tax liabilities. Similar to the asset side, the liabilities held

for sale include the liabilities in discontinued operations that were reclassified.

Statement of cash flows

The relevant starting point for gross cash flow in the first quarter of 2025/26 equals EUR 146.3m (previous year:

EUR 155.1m) and includes the result before income tax from the statement of operations as well as the results of discontinued operations (also see the transition in the notes to the consolidated interim financial statements on page xxx).

Gross cash flow rose by 9.5% over the previous year to EUR 180.9m in the first quarter of 2025/26. This increase was based primarily on a lower year-on-year negative correction for non-cash earnings components which was offset in part by the decline in the result before tax.

The development of working capital was negatively influenced by an increase in trade receivables as of the balance sheet date and a renewed increase in the capital commitment for EVN KG. These factors led to cash flow from operating activities of EUR -50.6m (previous year: EUR -32.1m).

Cash flow from investing activities totalled EUR 36.2m (previous year: EUR 12.6m). It reflects the increase in construction and investment subsidies in contrast to the year-on-year lower investment volumes as well as the further reduction of investments in cash funds which is reported under current financial investments.

Cash flow from financing activities totalled EUR -6.4m in the first quarter of 2025/26 (previous year: EUR -17.6m) and consisted chiefly of scheduled debt repayments. In

the previous year, this position also included the conclusion of a EUR 50m bank loan.

Cash flow amounted to EUR -20.8m in the first quarter

of 2025/26 (previous year: EUR -37.2m), and cash and cash equivalents equalled EUR 114.4m as of 31 December 2025 (previous year: EUR 24.7m). EVN had contractually committed, undrawn credit lines of EUR 765m at its disposal at the end

of the reporting period to service potential short-term financing requirements.

Shareholder structure

In accordance with Austrian federal and provincial constitutional law, the province of Lower Austria is the major shareholder of EVN AG with a stake of 51.0%. These constitutional requirements limit the transfer of the investment, which is held directly by NÖ Landes-Beteiligungsholding GmbH, St. Pölten.

The second largest shareholder of EVN AG is Wiener Stadt-werke GmbH, Vienna, with an investment of 28.4%. This company is wholly owned by the City of Vienna. EVN AG held 0.9% of the company's share capital as of 31 December 2025, and free float equalled 19.7%.

  Energy

  Increase in sales volumes of heat, decline in electricity and natural gas

• Decline in sales volumes of electricity and natural gas due to ongoing strong competition and the steady increase in customers' own electricity supplies from their photovoltaic and battery storage systems

• Increase in heat sales volumes resulting from the cooler weather and continuing concentration and expansion in the heat network

  EBITDA, EBIT and result before income tax below previous year

• Decline in revenue due to volume and price effects in the marketing of EVN's own generation; weather-related increase in revenue at EVN Wärme as a contrasting factor

• The declining prices were also reflected in lower costs, similar to the development of revenue.

• Lower earnings contribution from equity accounted investees: The further normalisation of earnings in the energy supply company EVN KG was slowed by the creation of a provision for the expected mandatory implementation of a social tariff for vulnerable households as part of the new Austrian Electricity Industry Act ("Elektrizitätswirt-schaftsgesetz", ElWG). In spite of this negative effect, EVN KG reported a nearly constant earnings contribution of EUR 7.2m for the reporting period (previous year: EUR 7.6m)

• End of electricity and gas supply business by EnergieAllianz in Germany as of 31 December 2025

  Continuation of high investment volume

• Main focal points: expansion of the district heating networks and connecting pipelines as well as the revitalisation and capacity expansion of existing district heating plants

• Completion of the biomass combined heat and power plant in St. Pölten

• Investments in charging infrastructure for e-mobility at several retail chains in Austria

  Pricing measures in energy supply in response to intensified competition in Austria

• As of 1 April 2026, EVN KG will offer household customers a new tariff with a twelve- month commitment at an average energy price of 10 cents net per kWh

1. The prior year values were adjusted to reflect the changed presentation of the Group's internal financing and distribution structure.

   Generation

   Electricity generation below previous year

   • Commissioning of new wind parks unable to completely offset the decline in wind flows; electricity generation from photovoltaics nearly doubles following the recommissioning of the photovoltaic plant in Dürnrohr, which was damaged by flooding in September 2024, and following the commissioning of new photovoltaic plants

   • Below average water flows

   • Since the contract for the provision of reserve capacity was not extended by the transmission network operator APG, the Theiss power plant will remain operational for the time being but is not producing for the market.

     EBITDA, EBIT and result before income tax substantially below previous year

   • Unfavourable generation conditions and lower market prices lead to decline in revenue

   • Generation-based lower earnings contribution from the equity accounted Verbund Innkraftwerke

   • Investment-related slight year-on-year increase in scheduled depreciation and amortisation

     Strong momentum for the expansion of renewable generation

   • Completion of the wind park in Gnadendorf (28.8 MW) -increase in total wind power capacity to 561 MW

   • Commissioning of the photovoltaic plant in Gaweinstal during October 2025 (EVN share: 3.3 MWp)

   • Examples of the projects currently in progress:

     • Repowering of the wind park in Ebenfurth (increase in installed capacity to 12.6 MW)

     • Construction of a wind park in Neusiedl an der Zaya (14 MW)

     • Repowering of the wind park in Grosssierning (increase in installed capacity to 26.5 MW)

     • Construction of a wind park in Grosskrut-Poysdorf (14 MW)

     • Construction of a photovoltaic plant in Ollersdorf (5.3 MWp)

   Adjustment of segment structure

   • The segment structure was adjusted beginning with the 2025/26 financial year to reflect the sale of the international project business; this caused a corresponding adjustment of the prior-year figures.

   • EVN Wasser, which is responsible for drinking water supplies in Lower Austria, is now assigned to the Networks Segment.

     Decline in electricity and natural gas network sales volumes

   • Decline in electricity network sales volumes to industrial and household customers caused by economic effects and increase in customers' own electricity supplies from their photovoltaic and battery storage systems

   • Decline in natural gas sales volumes to industrial customers; weather-related increase in demand from household customers as a contrasting factor

   • Decline in natural gas sales volumes intensified by the end of the Theiss power plant use for network stabilisation following expiration of the contract with the network transmission operator APG

     EBITDA, EBIT and result before income tax above previous year

   • Decline in cost of materials

   • Increase in upstream network costs

   • Positive non-recurring effect in connection with the acquisition of a company by kabelplus in December 2025

   • Higher volume of investments leads to increase in scheduled depreciation and amortisation

     Continuing high investments in supply security

   • Expansion and strengthening of infrastructure for green electricity feed-in (networks and substations)

   • New construction and expansion of 55 transformer stations; four were completed during the reporting period or are in the project conclusion phase

   • Investments in the digitalisation of network infrastructure

   • Construction of the eighth natural filter plant in Reisenberg, Lower Austria

     New system network tariffs for household customers as of 1 January 2026

     Improvement in revenue

   • Positive price effects as the main driver

   • System network tariffs for household customers in the 2025 calendar year increased by 32.0% on average for electricity and by 19.4% on average for natural gas

   • Positive revenue development also for Internet services and drinking water supplies

   • Increase of 6.9% on average in network tariffs for electricity announced by E-Control

   • Increase of 30.6% on average in network tariffs for natural gas

‌Notes to the consolidated interim report Accounting and valuation methods

Reporting in accordance with IFRS

The following standards and interpretations require mandatory application beginning with the 2025/26 financial year:

This consolidated interim report as of 31 December 2025, of EVN AG, taking into consideration § 245a of the Austrian Commercial Code (UGB), was prepared in accordance with the guidelines set forth in the International Financial Reporting Standards (IFRS) by the International Accounting Standards Board (IASB) as well as the interpretations of the International Financial Reporting Interpretations Committee (IFRIC) that were applicable at the balance sheet date and adopted by the European Union (EU).

EVN has exercised the option stipulated in IAS 34 to present condensed notes. Accordingly, the consolidated interim report contains merely condensed reporting compared to the Annual report, pursuant to IAS 34, as well as selected information and

IAS 21 The Effects of Changes in Foreign Exchange Rates 01.01.2025

details pertaining to the period under review. For this reason, it should be read together with the Annual report of the

2024/25 financial year (balance sheet date: 30 September 2025).

The accounting and valuation methods applied in preparing the consolidated financial statements as of 30 September 2025 remain unchanged, with the exception of the following new rules issued by the IASB which require mandatory application in the current financial year. The preparation of a consolidated interim report according to IFRS requires EVN to make assumptions

and estimates which influence the reported figures. Actual results can deviate from these estimates.

In order to improve clarity and comparability, all amounts in the notes and tables are generally shown in millions of euros (EURm) unless indicated otherwise. Immaterial mathematical differences may arise from the rounding of individual items or percentage rates. The financial statements of companies included in this consolidated interim report are prepared on the basis of unified accounting and valuation methods.

1) In accordance with the Official Journal of the EU, these standards are applicable to financial years beginning on or after the effective date.

The first-time mandatory application of the revised standards and interpretations has no material impact on the interim consolidated financial statements.

Seasonally-related effects on business operations

In particular, the energy business is subject to weather-related fluctuations in power generation and sales, thus lower revenue and earnings are typically achieved in the second half of the financial year.

Auditor´s review

The consolidated interim report was neither subject to a comprehensive audit nor subject to an auditor's review by chartered accountants.

EVN Letter to Shareholders 1st Quarter 2025 / 26 Key Figures Highlights Interim management report Segment reporting Consolidated interim report

Scope of consolidation

The scope of consolidation is established in accordance with the requirements contained in IFRS 10. A total of 27 domestic and 23 foreign subsidiaries (30 September 2025: 26 domestic and 23 foreign subsidiaries), including the parent company EVN AG, were fully consolidated as of 31 December 2025. As of 31 December 2025, a total of 12 subsidiaries were not consolidated due to their immaterial influence on the assets, liabilities, cash flows and profit and loss, both in detail and together (30 Septem-

ber 2025: 12).

1) Internal reorganisation

Kabelplus signed an acquisition and transfer agreement for the purchase of 100% of the insolvent Speed Connect Netzwerks-errichtungs GmbH (hereafter Speed Connect) in August 2025. The restructuring plan submitted by Speed Connect was accepted by the creditors' meeting on 3 November 2025, whereby its legal validity represented a closing condition for the acquisition and transfer agreement. The closing took place on 15 December 2025 after confirmation by the competent insolvency judge and the end of the legal appeal period. Following the conclusion of the acquisition, Speed Connect was initially included through full consolidation as of 31 December 2025. SCA Breitband GmbH, a subsidiary of Speed Connect, is currently in liquidation and not included in EVN's consolidated financial statements due to a lack of materiality.

Speed Connect was founded in 2022 with the goal to pursue wide-ranging glass fibre expansion in Austria's rural and periurban regions. The business model was based on an open access approach under which the installed wholesale network would be available to all Internet providers. Due to the economic development, insolvency proceedings were opened over the company's assets on 24 June 2025 at the debtor's request. The glass fibre expansion to date had taken place predominantly in the provinces of Lower Austria and Burgenland and can be connected to the kabelplus network with minimal expense. That creates synergy effects in kabelplus' area of activity as well as opportunities to supplement the existing business model.

The acquisition was initially recognised on a preliminary basis in accordance with IFRS 3.45 due to the complexity of the valuation and accounting issues. These issues involve, in particular, property, plant and equipment, deferred tax assets and inventories. The preliminary values will be adjusted within 12 months after the acquistion date if new findings to the existing facts and circumstances are identified.

The (preliminary) fair values of the acquired assets and assumed liabilities on the acquistion date are shown below:

EVN Letter to Shareholders 1st Quarter 2025 / 26 Key Figures Highlights Interim management report Segment reporting Consolidated interim report

Kabelplus purchased the shares in Speed Connect for a symbolic euro. The company was provided with EUR 2.9m to finance the mass credit, the cash quota and working capital. This amount is considered part of the consideration paid.

In addition, a shareholder loan for a purchase price of EUR 2.0m was assigned to kabelplus. The payment was made to the former owners and served to finance the share purchase.

The consideration paid for the purchase of the shares in Speed Connect totalled EUR 4.9m and was transferred on the acquisition date. The table showing the assets acquired and liabilities assumed does not include intragroup liabilities of EUR 4.9m attributable to Speed Connect because they are classified as consideration transferred. The difference between the fair value of the acquired assets and assumed liabilities equalled EUR 10.3m; it was recorded through profit or loss and included under other operating income. The resulting gain on the acquisition results, in particular, from opportunities to utilise loss carryforwards in the EVN Group, from the valuation of property, plant and equipment, and from the special features of a purchase process associated with insolvency proceedings.

If the acquisition had taken place at the beginning of the reporting period, revenue would have increased by EUR 0.1m and Group net result would have decreased by EUR 2.0m. This does not include the special effects from the restructuring measures.

There were no other acquisitions which fall under the scope of application of IFRS 3 during the reporting period.

Information on climate change and effects of the macroeconomic environment

For the possible effects of climate change and the macroeconomic environment, please refer to the disclosures in the consolidated financial statements as of 30 September 2025. In preparing the interim consolidated financial statements as of 31 December 2025, the EVN Group assessed, in particular, the recoverability of assets in accordance with IAS 36 and IFRS 9 as well as other uncertainties relating to discretionary judgements.

Against the background of the growing importance of climate risks, the company's strategic considerations include the special requirements created by the energy transformation and the far-reaching changes required by this transformation towards climate neutrality as well as the related effects on all sectors of the economy and on private households. Analyses in this context place a special focus on the requirements for climate protection, possible implementation tracks and the implications for the company's business model. These elements create an important basis for evaluating the opportunities and risks for our business resulting from climate change and the related, rapidly changing regulations.

The impact of climate change on asset valuation is evaluated at regular intervals. Climate-related fluctuations in earnings, whether due to production fluctuations or changes in demand, are analysed as part of the planning process and incorporated into the planning calculations after consultation with management. The measures derived from the EVN Climate Initiative are also incorporated into the planning calculations. These planning calculations subsequently form the basis for the impairment calculations

to be carried out in accordance with IAS 36.

The further development of the geopolitical and macroeconomic situation is uncertain due to the tense situation surrounding armed conflicts, sanctions and trade disputes, and could lead to rising energy prices again at any time. Volatile energy price developments have weighed on earnings in recent years, particularly in the sales business.

As in previous financial years, the EVN Group takes macroeconomic developments into account by applying a forward-looking component when assessing receivables. It determines the impairment requirement for trade receivables in accordance with IFRS 9 B5.5.35 on the basis of regionally differentiated analyses of historical payment defaults.

Apart from price developments on the energy markets and their varying effects on EVN's activities and business areas, the Group is affected by potential further cost increases in the context of its investments and operating expenses. All these price increases may only be passed on to customers with a delay. In addition, macroeconomic developments may also have a direct and indirect negative impact on energy demand and, together with cost increases, lead to a decline in earnings.

Thanks to low net debt and a comfortable level of contractually agreed, undrawn credit lines, EVN continues to enjoy a high degree of financial flexibility and solid liquidity reserves. Its integrated business model and broadly diversified customer portfolio have a particularly stabilising effect. At present, therefore, it can be assumed that the company will continue as a going concern.

As at 31 December 2025, there were no indications of impairment of the EVN Group's assets.

EVN Letter to Shareholders 1st Quarter 2025 / 26 Key Figures Highlights Interim management report Segment reporting Consolidated interim report

Notes to discontinued operations

On 10 December 2024, EVN and STRABAG SE reached an agreement on the key points of a possible sale of material parts of the EVN Group's international project business and subsequently negotiated binding transaction documents. As of 31 December 2024, the criteria have therefore been met to report the parts of the international project business held for sale in the consolidated financial statements in the Environment Segment as held for sale in accordance with IFRS 5. This reclassification specifically involves WTE Wassertechnik GmbH, which is headquartered in Essen, Germany, together with its subsidiaries, which are involved in either the operation of plants in Austria, Germany, Slovenia, Cyprus and Kuwait, or the construction of plants for drinking water supplies, wastewater disposal and thermal sewage sludge utilisation in Germany, Romania, North Macedonia, Croatia, Bahrain and Kuwait. As this is a significant line of business that covers almost the entire Environment Segment, it has been classified as a discontinued operation.

The binding transaction documents were finalised and the purchase agreement was signed on 18 June 2025. The closing is subject to receipt of the necessary approvals and third-party consent as well as the fulfilment of standard market conditions and is expected to take place by March 2026. As of 31 December 2025, the discontinued operations included the following assets and liabilities after the consolidation of all intragroup receivables and liabilities:

3.3

5.1

EVN's consolidated balance sheet contained assets of EUR 553.1m and liabilities of EUR 194.0m from the discontinued operations as of 31 December 2025. Intragroup receivables of EUR 1.4m and intragroup liabilities of EUR 280.0m from the discontinued operations were eliminated during the consolidation of liabilities in accordance with IFRS 10. The inclusion of these intragroup receivables and liabilities would increase the assets and liabilities of the discontinued operations to EUR 554.4m, respectively EUR 474.1m.

The purchase price agreed with STRABAG amounts to EUR 100m and is due and payable at the closing. In addition, part of the intragroup cash pool receivables due from the WTE Group will be assumed by STRABAG, and the remaining part will be transferred to WTE as equity prior to the closing. This transfer is defined as an earn-out purchase price and will be repaid by STRABAG from the future cash flows generated by defined projects. The amount of the earn-out purchase price is dependent on the balance of cash pool receivables on the closing date as well as the expected cash flows from the defined projects. The expected transaction price, less selling costs for the discontinued operations, was below the value of net assets as of 30 September 2025 and, consequently, resulted in an impairment loss of EUR 15.3m. A valuation according to IFRS 5.15 resulted in a revaluation of

EUR 2.5m as of 31 December. Therefore, the cumulative impairment as of 31 December 2025 totalled EUR 12.7m. The valuation effects are reported as part of the results from discontinued operations. The valuation as of the reporting date is dependent significantly on the amount and timing of the expected cash inflows from the projects designated for the earn-out.

The discontinued operations showed cumulative income of EUR 30.8m in other comprehensive income (OCI) as of 31 December 2025. It consisted primarily of foreign exchange differences as well as USD and KWD cash flow hedges to safeguard the cash flows from the wastewater project in Kuwait. The balance will be transferred to the consolidated statement of operations on the closing date.

The following table shows the income and expenses of the discontinued operations for the first quarter of 2025/26 and 2024/25.

Revenue by country

The share of results from equity accounted investees with operational nature decreased in the first quarter of 2025/26 to EUR 23.2m (previous year: EUR 47.1m). This decline was mainly due to lower operating earnings at RAG, Burgenland Energie and Verbund Innkraftwerke.

Earnings per share are calculated by dividing the Group net result (= net profit for the period attributable to EVN AG shareholders) by the weighted average number of shares outstanding, i. e. 178,306,081 as of 31 December 2025 (31 December 2024: 178,279,208 shares). There is no difference between basic earnings per share and diluted earnings per share. Calculated on the basis of a Group net result amounting to EUR 126.9m (previous year: EUR 115.5m), earnings per share at the balance sheet date 31 December 2025 totalled EUR 0.71 (previous year: EUR 0.65 per share).

Selected notes to the consolidated statement of financial position

In the first quarter of 2025/26, EVN acquired intangible assets and property, plant and equipment to the sum of EUR 163.7m (previous year: EUR 170.2m). Property, plant and equipment with a net carrying amount (book value) of EUR 1.3m (previous year: EUR 0.8m) were disposed of, with a capital loss of EUR 0.1m (previous year: capital gain of EUR 1.1m).

EVN Letter to Shareholders 1st Quarter 2025 / 26 Key Figures Highlights Interim management report Segment reporting Consolidated interim report

The other investments, mainly classified as FVOCI, include the Verbund shares held by EVN with a market value of EUR 2,720.7m, which has increased by EUR 4.4m since 30 September 2025 due to the development of the Verbund share price. In accordance with IFRS 9, the adjustments to the changed market values were offset with the valuation reserve after the deduction of deferred taxes.

The number of EVN shares in circulation developed as follows:

As of 31 December 2025, the number of treasury shares amounted to 1,572,321 (or 0.87% of the share capital) with an acquisition value of EUR 17.2m. The treasury shares held by EVN are not entitled to any rights, and in particular, they are not entitled to dividends.

The non-current loans and borrowings are composed as follows:

The bank loans include promissory note loans in the amount of EUR 337.0m (previous year: EUR 337.0m). The promissory note loans were issued in October 2012, April 2020, July 2022 and February 2025.

Segment reporting

1. The comparative information was adjusted due to the dissolution of a reporting segment.

2. Comparative periods were adjusted due to changes in the Group's internal financing structure.

3. In intangible assets and property, plant and equipment

The results shown in the total column represent the results reported on the consolidated statement of operations. The consolidation column reflects the elimination of intersegment transactions.

At the end of the 2024/25 financial year on 30 September 2025, EVN adjusted its internal organisational and reporting structure and dissolved the previous Environment Segment as an independent reporting segment. The reason for this is the initiated sale of significant parts of the international project business, which are reported as discontinued operations in accordance with IFRS 5. The activities of EVN Wasser will be allocated to the Networks Segment in future. All other activities of the previous Environment Segment have been presented in All Other Segments reporting segment since 1 October 2025. In accordance with IFRS 8.29, the previous year's figures in the segment reporting have been retrospectively adjusted to present the new segment structure in a comparable manner.

EVN Letter to Shareholders 1st Quarter 2025 / 26 Key Figures Highlights Interim management report Segment reporting Consolidated interim report

The previous table shows the financial instruments carried at fair value and their classification in the fair value hierarchy according to IFRS 13.

Level 1 input factors are observable parameters such as quoted prices for identical assets or liabilities. These prices are used for valuation purposes without modification.

Level 2 input factors represent other observable parameters which must be adjusted to reflect the specific characteristics of the valuation object. Examples of the parameters used to measure the financial instruments classified under Level 2 are forward price curves derived from market prices, exchange rates, interest structure curves and the counterparty credit risk.

Level 3 input factors are non-observable factors which reflect the assumptions that would be used by a market participant to determine an appropriate price.

There were no reclassifications between the various levels during the reporting period.

Hedging transactions designated as cash flow hedges (portfolio hedge electricity) are presented together with derivative financial instruments measured at fair value through profit or loss. A separate presentation is not possible due to the netting of derivative financial instruments as a result of standard netting agreements in the energy sector.

Other obligations and risks

Other obligations and risks increased by EUR 91.3m to EUR 1,332.7m compared to 30 September 2025. This change was mainly due to the increase in scheduled orders for investments in intangible assets and property, plant and equipment and an increase in guarantees in connection with energy transactions. This was partially offset by a reduction in guarantees in connection with the construction and operation of power plants and by a reduction in guarantees for environmental projects.

Contingent liabilities relating to guarantees in connection with energy transactions are recognised in the amount of the actual risk for EVN for those guarantees issued for the procurement or marketing of energy. This risk is measured by the changes between the stipulated price and the actual market price, whereby EVN is only exposed to procurement risks when market prices decline and to selling risks when market prices increase. Accordingly, fluctuations in market prices may lead to a change in the risk exposure after the balance sheet date. The risk assessment resulted in a contingent liability of EUR 125.7m as of 31 December 2025. The nominal volume of the guarantees underlying this assessment was EUR 462.2m
