Looking back at 2023

As the CEO and Chief Sustainability Officer, I am pleased to present Uniper's eighth Sustainability Report. It is a testament to our dedication to systematically improving sustainability performance across all facets of our operations and supply chains. I am proud to share the progress we have made.

2023 was an exciting year for Uniper. In August we announced our new strategy:"Accelerating the energy transition: flexible, balanced, bespoke." Europe wants to reduce its greenhouse- gas emissions by at least 55% by 2030 and to achieve climate neutrality by 2050. Germany aims to be climate-neutral by 2045. Uniper wants to achieve this already by 2040. This is a truly mammoth task. But we consider Uniper to be very well positioned for these changes. We are playing a decisive role in transforming the energy system, which you can read about in this report.

Throughout 2023, we made significant strides in various aspects of sustainability. Uniper was named as one of the world's best employers and earned the gold Pride Champion seal. We carried out several projects that enhance biodiversity and promoted activities that support both the physical and mental health of our employees. We continued to discuss ESG risks and impacts with several international NGOs and high-risk suppliers. These are just a few examples.

Uniper's sustainability journey is ongoing, and I recognize that there is always room for improvement. As we move forward, we remain dedicated to finding innovative solutions and collaborating with stakeholders to address the most pressing sustainability challenges of our time.

I would like to express my gratitude to all our employees who have contributed to our sustainability efforts. Together, we can create a more sustainable future for generations to come.

Best wishes,

Michael Lewis

Our report

Uniper has published an annual Sustainability Report for each year since 2016, when we became an independent company. This is therefore our eighth Sustainability Report. It is available in English and German. It presents information about our most material sustainability topics, how we manage them, and what we achieved in the reporting period. The reporting period is the calendar year 2023.

Majority shareholders

The majority shareholder of Uniper SE is the Federal Republic of Germany, with a 99.12% stake in Uniper. This was the result of the financial stabilization pack- age, which totaled around €13.5 billion and the acquisition of the Uniper share package from Fortum.

Our report

This report's description of our materiality assessment and management approach reflects the Global Reporting Initiative's standards (GRI). The report uses GRI indicators to disclose information on selected issues; their use is referenced in each instance. We are working toward reporting 100% in accordance with the GRI Standards: Core Option to provide our stakeholders with an even more comprehensive overview. The sections of this report that fulfill a GRI standard are identified with the corresponding standard in the GRI Index, which is published together with this report on the Uniper website.

Uniper's material issues have been clustered into three impact areas: Planet, People & Society, and Responsible Governance. This report is structured according to these three impact areas.

This Sustainability Report is published as a PDF, which can be downloaded from our website. Uniper also reports on its sustainability progress in interim quarterly reporting.

This report supersedes the Uniper Sustainability Report 2022.

Personnel changes in the Supervisory Board and the Board of Management

Personnel changes in the Uniper Supervisory Board and the Board of Management occurred in 2023. On January 20, 2023, the Supervisory Board of Uniper SE appointed Dr. Jutta A. Dönges to the Board of Management of Uniper SE as CFO effective March 1, 2023. Dr. Jutta A. Dönges, who had been a member of Uniper SE's Supervisory Board since December 2022, resigned from the Supervisory Board of Uniper SE effective at the end of February 2023. On March 1, 2023, the new Chief Operating Officer, Holger Kreetz, also joined Uniper's Board of Management. Holger Kreetz was previously head of Uniper's Asset Management division. On June 1, 2023, Michael Lewis started at Uniper as the new CEO and, due to the strategic importance of sustainable business development for Uniper as a whole, he also assumed the role of Chief Sustainability Officer (CSO). Carsten Poppinga completed Uniper's Board of Management, joining as the new Chief Commercial Officer (CCO) on August 1, 2023.

Dr. Gerhard Holtmeier, who had been Managing Director of Uniper SE's parent company, UBG Uniper Beteiligungsholding GmbH, with its registered office in Berlin (Charlottenburg District Court, HRB 248168 B), since December 2022, joined the Supervisory Board of Uniper SE as a new member effective March 21, 2023. He was nominated by the Federal Ministry of Finance and UBG to succeed Dr. Jutta A. Dönges on the Supervisory Board. The Düsseldorf District Court had appointed Dr. Gerhard Holtmeier and additional shareholder representatives as members of the Supervisory Board. Shareholders then formally elected the initially court-appointed shareholder representatives to the Supervisory Board at the Annual General Meeting on May 24, 2023. At its inaugural meeting on May 24, 2023, the Supervisory Board subsequently elected Tom Blades as Chairman of the Supervisory Board. Prof. Dr. Ines Zenke was elected Deputy Chairwoman of the Supervisory Board. Harald Seegatz also holds the office of Deputy Chairman of the Supervisory Board as an employee representative.

Uniper

Sustainability Report 2023

Our strategy and purpose are fully dedicated to sustainability. We once again performed an extensive materiality analysis in 2023 to reassess which sustainability topics are most material for Uniper.

Materiality assessment

Understanding our stakeholders' views and expectations is crucial to Uniper's success and the public's acceptance of our operations. It is also of great importance for Uniper to understand its impact on environmental, social, and governance (ESG) issues. We conduct an annual materiality assessment to identify which issues our sustainability efforts should focus on most. An issue's materiality reflects its relevance to our business, our stakeholders, and the estimated magnitude of its impact on Uniper and of Uniper's impact on the issue.

The first dimension of the materiality assess- ment, business impact, involves an in-depth study to assess the impact of a number of eco- nomic, environmental, and social issues on Uniper and the impact of Uniper's business activities on the issues. The issues are evaluated in relation to their significance from the standpoint of the law, the public interest, Uniper's competi- tors, and ESG ratings. Correlations between the issues and the UN Sustainable Development Goals (SDGs) are also examined. An update of

the business impact study was performed in 2023 to take into account relevant developments.

The second dimension of the materiality assess- ment, stakeholder expectations, considers the view of Uniper's internal and external stakehold- ers. In 2023, stakeholder expectations were compiled by means of surveys in which participants were asked to rate the importance of Uniper's material issues. Participants included Uniper employees and management, and representatives from the main external stakeholder groups, such as non-governmental organizations (NGOs), customers, and investors.

The following materiality matrix provides an overview of the assessment's findings. The horizontal axis indicates the issues' impact on Uni- per's business and Uniper's impact on the issue. The vertical axis indicates the issues' relevance from a stakeholders' perspective. As in recent years, "Climate Change and GHG," "Secure and affordable energy supply," and "Emissions to air, land, and water" are Uniper's three most material topics.

The various sections of this report describe Uni- per's management approach for the issues, the progress it achieved in the reporting period, and, where appropriate, exceptions to its definition of materiality.

How Uniper contributes to the SDGs

Ratings and rankings

In August Uniper announced its new corporate strategy: "Accelerating the energy transition: flexible, balanced, be- spoke." Our new strategy is to use our unique combination of capabilities - flexible and increasingly green power, reliable and increasingly green gas, and system optimization - to accelerate Europe's transition toward carbon neutrality. And, consistent with our heritage, we will continue to ensure supply security for our markets. All of this is captured in our new motto: Uniper - the beating heart of energy.

Uniper has developed the Strategic Sustainability Plan (SSP) to support the corporate strategy and to actively manage and minimize the main negative environmental and social impacts of its business activities and to set commitments and targets to improve ESG performance.

Our approach

The SSP groups the material issues derived from the materiality assessment into three categories: Planet, People & Society, and Responsible Governance. These categories provide the framework for the development of specific commitments, targets, and action plans in alignment with selected UN Sustainable Development Goals (SDGs). The long-term commitments reflect the core elements of Uniper's corporate culture and strategy and build the basis for the SSP targets.

The SSP is Uniper's main tool for defining and managing appropriate risk-mitigation and impact-remediation measures for material issues. This accords with the recommendations of international frameworks, such as the OECD Guidelines for Multinational Enterprises. The SSP seeks to not only mitigate impacts but, where relevant, take proactive steps and seize opportunities to have a positive impact on ESG issues. It aims to ensure systematic monitoring and review of Uniper's sustainability performance and ambitions. The HSSE & Sustainability function tracks this performance and progress, and reports on it by means of quarterly reviews for the Management Board and senior manag- ers. Uniper discloses its progress on at least an annual basis in external reports.

Highlights 2023

In 2023 Uniper made more progress implementing the commitments defined in the SSP. We made a number of new commitments and set new sustainability targets as part of the adoption of our new strategy in August 2023. For example, we raised our climate ambitions. We now aim to reduce our carbon emissions by 55% by 2030 and to be carbon-neutralGroup-wide by 2040 - ten years earlier than previously planned. We also set the ambition for women to hold 30% of leadership positions by 2030. In addition, we underscored our commitment to a just transition and NGO engagement and intend to enhance our performance management and create comprehensive frameworks for these issues.

Uniper will further refine its SSP approach in 2024 to align it with the new EU Corporate Sustainability Reporting Directive (CSRD) and the strategic pillars of our new corporate strategy. We will revise the SSP in 2024 to consider new targets, commitments, and KPIs for topics such as decarbonization, biodiversity, NGO en- gagement, just transition, and innovation.

This Sustainability Report provides additional insights into our management approach for material issues and our approach to the new commitments.

Uniper. The beating heart of energy.

Uniper's contribution to the Sustainable Development Goals

Foreword

Our report

Our material topics and sustainability strategy

The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet now and into the future. At its heart are the 17 Sustainable Development Goals (SDG) - an urgent call for action by all countries in a global partnership. They recognize that ending poverty and other deprivations must go hand

in hand with strategies that improve health and education, reduce inequality, and spur economic

growth - all while tackling climate change and working to preserve our oceans and forests (source: www.praeventionstag.de). We recognize the importance of all the 17 SDGs and fully support them. We have prioritized 10 SDGs that are particularly relevant to our business activities, strategy, and material topics. Here are some examples of how Uniper contributed to the 10 prioritized goals in 2023.

Alongside the diversity, equity and inclusion (DEI) ambassador net- work, Uniper's employee-led resource groups are instrumental in promoting and supporting DEI - for instance, Women@Uniper (inter- nal women's network) and Uniper's LGBTQIA+ network. All of these groups continued their activities in 2023 and increased their mem- bership.

In 2023, Uniper also commissioned the Association of Compensation & Benefits Experts (ACBE) to audit its compensation scheme in order to identify potential gender pay gaps. The audit confirmed that Uniper's pay equity in Germany is within the tolerance limit of 5% and the Company was awarded the "Fair Compensation" certificate.

1. Diversity, equity, and Inclusion

We intend to increase our new renewable energy capacities primarily through onshore wind and solar in Europe. In late August 2022, Uniper received regulatory approval to build a 17 MW solar farm at our former coal-fired power plant in Wilhelmshaven on Germany's North Sea coast. This project is expected to generate approximately 16,000 MWh of renewable electricity per year.

In 2023, Uniper embarked on a project to build a 300 MW solar farm outside Elsfleth, a town located about 30 kilometers northwest of Bremen. Additionally, Uniper announced in November 2023 six ready- to-build solar projects in Hungary with a combined capacity of 280 MW. They will start producing green electricity by 2027.

1. Climate change and greenhouse gas emissions

In 2023, Nyckeltalsinstitutet AB, a Stockholm-based people analytics firm, again recognized Uniper as an excellent employer and, indeed, as Sweden's Best Employer. The award considers data and scientific analyses of working conditions such as health care, salary, sick leave, management setup, and career opportunities.

In 2023, the US-based Institute for Quality named Uniper one of the world's best employers in Germany. It drew on 55 different sources (including rating portals, career websites, and media coverage) to assess the attractiveness of more than 74,000 companies on topics like sustainability and new work.

In 2023, we had 21 new trainees take part in our 18-to-24-month pro- gram, which assigns them to various roles depending on their individual interests and career plans. More than 95% of those who completed the program between 2016 and year-end 2023 took on a permanent role at Uniper.
