"United States segment: compliance risk assessment

As a US-listed company, T-Mobile US conducts a risk assessment based on its own methodology. The outcome is regularly reported to the relevant bodies, including representatives of Deutsche Telekom AG. Before T-Mobile US selects suppliers, a centralized Third-Party Risk Management (TPRM) process screens for anticorruption, global sanctions, and human rights violations, as well as financial, security, reputational, and environmental risks. Supplier risk assessments are performed on an ongoing basis depending on the risk profile of the supplier. Automated, real-time workflows in TPRM look for any adverse news or changes in supplier risk profiles and continually monitor current suppliers for policy violations and risks. Events or issues detected by TPRM monitoring are escalated to the enterprise legal, compliance, and business teams for review and recommended handling.

T-Mobile US expects its affiliates, business partners, suppliers, and their stakeholders to comply with its Human Rights Statement. This covers areas such as discrimination, working conditions, and freedom of expression. Furthermore, T-Mobile US uses its Responsible Sourcing Policy to encourage suppliers to set their own science-based emissions reduction targets, and the policy tracks supplier performance through regular assessments managed by EcoVadis"

"When selecting suppliers, our procurement organization focuses on ensuring that we cooperate with efficient, reliable suppliers that work with sustainability in mind. This will allow us to safeguard our capacity to innovate and competitiveness over the long term. When selecting suppliers, we include sustainability criteria in the decision. CO₂ emissions are generally weighted with 20 percent as part of tenders.

As part of supplier management, there are various processes that aim to minimize the risks in the supply chain and to increase its sustainable further development. We set out our minimum requirements for our suppliers in the SCoC to ensure compliance with the requirements along the value chain. With strategic procurement processes, suppliers are registered on our supplier portal. The supplier qualification then begins where suppliers are vetted in relation to various criteria."
