Current report
We rely on highly skilled personnel throughout all levels of our business. Our business could be harmed if we are unable to retain or motivate key personnel, hire a sufficient number of qualified new personnel, or maintain our corporate culture.
Current report
Our future success depends in substantial part on our ability to attract, recruit, hire, motivate, develop, and retain talented personnel possessing the qualifications, experiences, capabilities and skills we need for all areas of our organization, including our CEO and members of our senior leadership team. Succession planning to ensure effective transfer of knowledge and a seamless transition when key personnel depart is also important to our long-term success. In September 2025, we announced that on November 1, 2025, G. Michael Sievert would retire as our Chief Executive Officer and continue to serve as Vice Chairman of the Company and Vice Chairman of our Board of Directors, and Srinivasan Gopalan would serve as our Chief Executive Officer. Our ability to execute our business strategies and retain key executives may be adversely affected by the transition. Additionally, as we continue to make significant investments in new technologies and new business areas, we are increasingly dependent on being able to hire and retain technically skilled employees, including those with expertise in AI and machine learning.
Current report
Both external factors, such as fluctuations in economic and industry conditions, changes in U.S. immigration policies, regulatory changes, political forces and the competitive landscape, and internal factors, such as employee tolerance for changes in our corporate culture, organizational changes, limited remote working opportunities, and our compensation programs, may impact our ability to effectively manage our workforce. Further, employee compensation and benefit costs may increase due to inflationary pressures, and if our compensation does not keep up with inflation or that of our competitors’, we may see increased employee dissatisfaction and departures or difficulty in recruiting new employees. If key employees depart or we are unable to recruit and integrate new employees successfully, our business could be negatively impacted.

Previous wording
We have entered into joint venture agreements aimed at establishing a robust fiber broadband network that complements our fixed wireless services. Once closed, differences in views among the joint venture participants may result in delayed decisions or disputes. Operating through joint ventures in which we do not hold a majority ownership interest results in us having limited control over many decisions made with respect to the businesses of the joint ventures. We also cannot control the actions of our joint venture partners. These joint ventures may not be subject to the same requirements regarding internal controls and internal control over financial reporting that we follow. As a result, internal control problems may arise with respect to these joint ventures. Any of these risks could have a material adverse effect on our business, financial condition and results of operations and could also affect our reputation.
