Special Events in the Reporting Period

Corporate Bonds Issued

E.ON issued several corporate bonds totaling €3.5 billion in the first nine months of 2022.

• €500 million bond that matures in January 2026 and has a coupon of 0.125 percent (January 2022)
• €800 million green bond that matures in October 2034 and has a coupon of 0.875 percent (January 2022)
• €750 million green bond that matures in January 2025 and has a coupon of 0.875 percent (March 2022)
• €750 million green bond that matures in March 2031 and has a coupon of 1.625 percent (March 2022)
• €600 million bond that matures in August 2028 and has a coupon of 2.875 percent (August 2022)
• NOK 1,500 million private placement that matures in September 2032 and has a coupon of 5.02 percent (September 2022). It is fully hedged for interest rate and currency. Including the hedging transaction, this yields a euro-denominated liability of roughly €150 million with an interest rate of 3.70 percent per annum.

Russia's Invasion of Ukraine Creates Significant Macroeconomic Uncertainty and Impacts the Energy Sector

On February 24, 2022, Russia attacked Ukraine. As a result of Russia's attack against Ukraine, which is a violation of international law, the situation on energy markets remains tense. E.ON's priority in these turbulent times is to secure the energy supply. The power, gas, and heat networks that E.ON operates in

various regions of Europe are running stably, even in the current situation.

The war's repercussions also have implications for E.ON's business, in particular because of higher commodity prices. These implications are described in greater detail below in the sections entitled "Earnings Situation" and "Financial Situation." In addition, our 2021 Annual Report provided commentary on other possible risks for E.ON. One of them is a possible measurement risk for financial assets, including the investment in Nord Stream AG held in pension plan assets. Measurement of this investment at September 30, 2022, declined to €0.1 billion. Among the reasons for this are greater uncertainty amid the current situation and, since September 26, damage to both of Nord Stream 1's pipelines whose cause is as yet unclarified. This decrease in fair value was recognized in equity in other non-operating income. The situation assessable at the balance-sheet date indicated no other triggering events that would necessitate impairment charges on non- current assets, in particular goodwill, other intangible assets, and property, plant, and equipment.

The German federal government's efforts to find ways out of the energy crisis have begun to bear fruit. For example, the country's gas storage facilities were already more than 95 percent full by mid- October, in part because France had begun supplying gas to Germany in October. Partnerships for the supply of liquefied natural gas ("LNG") constituted another factor. In addition, the German federal government has put in place a series of measures to ensure energy independence and supply security. They include steps to increase energy efficiency, regulations for the return of coal- and oil-fired power plants to the electricity market, ways to expand renewables capacity in the near term, and an energy-conservation ordinance.

To ease the burden on private consumers and industry, in the period under review, the German federal government not only temporarily reduced the VAT on gas consumption, it also announced what is now its third relief package. The package consists of short-term assistance and also structural changes to attenuate the rise in energy prices for

end-customers. Legislators are expected to begin enacting the laws and ordinances in the weeks ahead.

The EU is also seeking ways to resolve the energy crisis. In October, the European Commission likewise presented a new package of measures to limit gas prices. In the short term, the Commission envisages limiting wide fluctuations in gas prices by establishing a "dynamic corridor"; the details have not yet been worked out.

Conclusion of a Future Consolidation Agreement with ZSE Shareholders

On April 8, 2022, the shareholders of Západoslovenská energetika a.s. ("ZSE") and of Východoslovenská energetika Holding a.s. ("VSEH"), E.ON SE, and the Slovak Republic, concluded a Future Consolidation Agreement to combine ZSE and the VSEH Group. The agreement provides, among other things, for 100 percent of VSEH shares to be transferred to ZSE, the sale of all or selected VSEH subsidiaries to ZSE, and the implementation of corporate law changes at VSEH.

The transfer of VSEH shares to ZSE will result in ZSE becoming VSEH's sole shareholder (and thus also shareholder of selected VSEH subsidiaries). The ownership interests in ZSE will remain unchanged; that is, E.ON will have a 49-percent stake in VSE and the Slovakian state a 51-percent stake. The new ZSE shareholders agreement, which has yet to be concluded, will essentially correspond to the current shareholders agreement. After the transaction, ZSE will thus continue to be included in E.ON's Consolidated Financial Statements as a jointly owned company and accounted for using the equity method. After closing, the VSEH's

business operations, which previously had been fully consolidated, will be accounted for using the equity method.

It is now assumed that the transaction can be completed in the first half of 2023.

Disposal of Universal Service Provider Business in Hungary To further optimize E.ON's portfolio in Hungary, E.ON Hungária

Zrt. signed an agreement with MVM Zrt. on February 23, 2022, to sell 100 percent of its stake in E.ON Áramszolgáltató Kft. ("EÁS"). EÁS holds a regional universal service provider license under which it supplies electricity to customers in certain regions of Hungary. The transaction closed on April 14, 2022.

Science Based Targets Initiative Confirms E.ON Targets for Reducing CO2 Emissions

E.ON systematically promotes the sustainable development of the energy world. This focus is also reflected in E.ON's ambitious climate targets, which in late May 2022 were officially validated by the Science Based Target Initiative ("SBTi"). E.ON's Group-wide sustainability strategy explicitly commits it to the Paris Climate Agreement's 1.5 degree target. Against this backdrop, E.ON set science-basedemission-reduction targets.

E.ON's stated objective is to be climate-neutral by 2040 and to reduce the emissions that it can directly influence (Scope 1 and 2) by 100 percent by this time. By 2050, E.ON also aims to reduce its Scope 3 emissions by 100 percent relative to 2019.

E.ON and Igneo Establish Joint Venture for Accelerated High- Speed Broadband Rollout

In mid-July, E.ON and Igneo Infrastructure Partners signed an agreement to found a joint venture for the rollout of high-speed broadband infrastructure in Germany. For this purpose, Igneo acquired a 50-percent stake in Westconnect GmbH (formerly Westenergie Breitband GmbH), which was previously a wholly owned E.ON SE subsidiary. The transaction closed on October 31, 2022. In the future, the joint venture intends to provide fiber-

optic broadband connections to more than 1.5 million households and wholesale customers in Germany.

E.ON subsidiary Westenergie remains a 50-percent shareholder; the company's activities will be recorded in E.ON's Consolidated Financial Statements using the equity method.

On Capital Markets Day in the fall of 2021, E.ON announced that it planned to conduct €2 to €4 billion of portfolio optimization. The Igneo transaction is the first such measure.

Contract of Management Board Chairman Leonhard Birnbaum Extended to 2028

At its meeting in late September 2022, the E.ON SE Supervisory Board extended the contract of Management Board Chairman Leonhard Birnbaum by five more years until June 30, 2028. Birnbaum has been a member of the E.ON Management Board since 2013 and its Chairman since April 2021.

Subsequent Events

Agreement on the Temporary Continued Operation of Germany's Remaining Nuclear Power Plants

E.ON supports the German federal cabinet's decision to amend the Atomic Energy Act to stipulate the continued operation of the three nuclear power plants ("NPPs") that remain online. This will enable generating capacity to be maintained in the coming winter to stabilize the German power grid. Under the amendment, the authorization of Emsland, Neckarwestheim 2, and Isar 2 NPPs (the latter of which is operated by PreussenElektra, an E.ON subsidiary) to operate would not expire until the close of April 15, 2023. The Bundesrat and Bundestag will discuss the draft legislation in November. Germany's NPPs can make a valuable contribution toward securing the energy supply amid the crisis and put downward pressure on prices. Isar 2 NPP will shut down briefly to overhaul pressurizer pilot valves so that it can continue operating. After restart, the plant can operate with the existing reactor core until April 15, 2023, at the latest. PreussenElektra could earn power-market revenues for about 2 TWh of Isar 2's electricity output

during this period next year. These potential revenues must be set against the additional costs arising from the extension and any laws that might apply to the treatment of electricity market revenues. E.ON plans that any possible revenues resulting from Isar 2's continued operation will be used for the energy transition, such as for network infrastructure and the development of its hydrogen business.
