Here you can find KPIs for Deutsche Telekom's central compliance measures.
Our compliance culture is an essential part for corporate governance geared towards integrity and appreciation. We are committed to ethical principles as well as to the law throughout the Group. We have anchored this in our guidelines and our Code of Conduct. We also provide further compliance information in the Annual Report.
Prevent
Corruption violates national and international law. We reject all forms of corruption – both bribery as active corruption and corruption as passive corruption – in the public and private sectors. Our compliance management system (CMS) is therefore particularly geared towards preventing corruption.
We have implemented a compliance management system with the aim of minimizing risks from systematic violations of legal or ethical standards that could lead to regulatory or criminal liability of the company, its board members or employees or to significant reputational damage. The Executive Board assumes its overall responsibility for compliance as a key management task. Our Chief Compliance Officer is responsible for the design and management of the compliance management system. At the level of our operating segments and national companies, compliance officers implement the compliance management system and our compliance targets locally.
The Compliance Risk Assessment (CRA) is one basis of our compliance management system. It enables us to identify and assess compliance risks and initiate appropriate preventive measures. For this purpose, we have set up a process that has to be run through regularly. The selection of companies participating in the CRA is risk-oriented.
Group Compliance department provides central support for local assessments and provides a standardized methodology. This methodology defines that risks are evaluated in terms of likelihood of occurrence and potential damage. Existing preventive measures are considered in managing the risk. If necessary- new mitigating measures be derived.
In 2025, the CRA was conducted in 51 subsidiaries in Germany and abroad, with a focus on the German Supply Chain Due Diligence Act (LkSG). The regular, broader standard CRA was conducted in 2024 at Deutsche Telekom AG and 101 other subsidiaries in Germany and abroad. The next risk assessment is planned for 2026.
As a U.S.-listed company, T-Mobile US conducts a risk assessment using its own methodology, on which it regularly reports to the relevant committees (where also representatives of Deutsche Telekom AG are members).
We regularly have our compliance management system with a focus on "anti-corruption" audited by independent auditors according to Assurance Standard 980 by the German Institute of Public Auditors (“IDW”). The audits focus on general compliance processes as well as on processes that are exposed to an increased risk of corruption: e.g., in the areas of procurement, sales, events, donations, sponsoring, mergers & acquisitions and human resources.
After an IDW PS 980 audit of Deutsche Telekom AG and eight other subsidiaries in Germany was carried out in 2024, twelve international subsidiaries were audited according to this audit standard in 2025. In addition to compliance processes, the audits once again focused in particular on processes that are exposed to an increased risk of corruption. As in the previous audits, the effectiveness of the compliance management system with a focus on "anti-corruption" of all audited international subsidiaries was confirmed.

AskMe – To prevent compliance risks, we operate a helpline for our employees, the consulting portal AskMe, for questions about value- and legally compliant behavior or other compliance issues. Queries that are assigned to the Group Compliance department's responsibility in terms of content are answered directly here. Queries that are the responsibility of other departments will be forwarded to them.
The following diagram shows the number of queries to AskMe received by topic.
Information and Training of Employees
On our intranet, we offer our employees comprehensive information about compliance. In addition, we regularly train and sensitize our employees through compliance training and other compliance information such as newsletters or mailings. Classroom training and various eLearning formats on compliance topics are available. Specially tailored classroom training courses on compliance and anti-corruption are held for managers and executives regularly. The training content sensitizes managers to their special role and responsibility.
Participants Compliance Trainings - group-wide
Our eLearning offer on compliance is established and also addresses the value-based, integrity and cultural aspects of compliance.
In 2023, we rolled out the eLearning "Basic Knowledge Compliance" (T-Mobile US has its own training). This deals with the principles of compliance code of conduct, conflicts of interest and anti-corruption and includes a self-check for decisions in difficult situations (ICARE-Check). Since the rollout at the end of August 2023 until the end of the year 2025, 89% of employees have completed the eLearning “Basic Knowledge Compliance”. The campaign will continue in 2026. The eLearning is reviewed every 24 – 36 months for up-to-dateness, revised if necessary and rolled out again This eLearning as well as other compliance trainings such as anti-corruption or digital ethics are accessible to approximately 130,000 employees. To ensure sufficient competence in dealing with Artificial Intelligence (AI) in accordance with the EU AI Act, we offer our employees an eLearning Digital Ethics as well as, promtathons, AI-Learning Journeys, LEX Sessions (Learning from Experts) etc.
At T-Mobile US, more than 91% took part in a Business Integrity Training, which is divided into different episodes. The company culture is fundamental for all teams - it determines the way we treat each other, how we work together. Particularly in the case of upcoming changes, the compliance culture, which aims to behave in accordance with the law and with integrity, is therefore always considered and shaped. We obtain information on the compliance culture through relevant statements in the employee survey.
As the world becomes increasingly complex and we are all confronted with new challenges and regulations every day, it is more important than ever to sharpen the inner compass of our employees so that they can act confidently and with integrity in different situations. For this purpose, we have developed the ICARE Check, a self-test with five simple questions. It provides guidance to all employees on how to make a responsible decision in difficult situations.

In addition, best practice examples are discussed in regular worldwide virtual meetings. Through the exchange, all units can learn from each other and make targeted improvements for their CMS.
