U.S. Cellular (NYSE: USM), an 83%-owned subsidiary of Telephone & Data Systems (NYSE: TDS) announced today that Laurent C. Therivel ("LT") will be appointed President and Chief Executive Officer, effective July 1, 2020. Kenneth R.

Therivel will also be appointed to replace Meyers on both the U.S. Cellular and TDS Boards of Directors.

Therivel, 45, joins U.S. Cellular from AT&T where he served most recently as CEO of AT&T Mexico, a wireless company that operates under the AT&T and Unefon brands, where he led a team of over 18,000 employees.

"As a result of an orderly succession planning process and an extensive search, we are very pleased to announce LT's appointment," commented LeRoy T. Carlson, Jr., Chairman of U.S. Cellular and President and CEO of TDS. "With his deep experience in the telecommunications industry, LT brings tremendous insight and perspective to this role. During his years at AT&T he had a variety of important assignments leading wireless and wireline operations, strategy and finance. He is highly customer-focused which aligns well with U.S. Cellular's mission of providing exceptional wireless experiences to our customers. I am confident LT's leadership, experience and collaborative style will build upon the success that U.S. Cellular has achieved under Ken Meyers' leadership."

"I look forward to joining U.S. Cellular, which is in a strong position to continue providing customers with high-quality wireless service," said Therivel. "More than ever, the essential nature of our solutions has been validated over the past few months during the pandemic. I am excited to work alongside U.S. Cellular's talented management team and with all of its associates to build on the successes of its customer and community-focused strategies. I am honored to have the opportunity to contribute to U.S. Cellular's bright future and am intensely focused on working toward long-term growth and sustainability."

"We greatly thank Ken for his many years of exemplary service to U.S. Cellular and the TDS Enterprise," continued Mr. Carlson. "This includes his many contributions to the growth and development of thousands of associates through 33 years of dedicated leadership. We wish him much health and happiness during this next chapter in his life."

"Ken has spent over three decades of his career with TDS and U.S. Cellular in a variety of leadership positions including executive vice president and CFO for both Companies. Throughout his time as CEO, Ken applied his deep understanding of our industry, as well as his strategic and financial knowledge to further improve U.S. Cellular's performance and operational efficiency. He led and developed a strong senior management team to execute aggressive, yet economically sound, customer-focused strategies. Ken's effective leadership and commitment to the Company's culture will leave a lasting effect on U.S. Cellular."
