The companies also announced agreements with DISH Network Corporation (NASDAQ: DISH) in which the combinedT-Mobile and Sprint, as the proposed NewT-Mobile, will divest Sprint’s prepaid businesses and Sprint’s 800 MHz spectrum assets to DISH. Additionally, upon the closing of the divestiture transaction, the companies will provide DISH wireless customers access to the NewT-Mobile network for seven years and offer standard transition services arrangements to DISH during a transition period of up to three years. DISH will also have an option to take on leases for certain cell sites and retail locations that are decommissioned by the NewT-Mobile, subject to any assignment restrictions.

We are pleased that our previously announced target synergies, profitability and long-term cash generation have not changed,” saidT-Mobile CEO and NewT-Mobile CEO John Legere.

“Today marks an incredibly important step forward for the NewT-Mobile. We are ready to bring this superchargedUn-carrier to consumers and businesses across the country, and this milestone brings us much closer to making that vision a reality for customers everywhere!” said Legere. “Our goal was to ensure that the DOJ’s concerns were addressed while enabling us to deliver on every aspect of the synergies we promised to unlock… and we did it. It may have taken longer than expected by some, but today’s results are awin-win for everyone involved. We cannot wait to get to work bringing thispro-consumer,pro-competition NewT-Mobile 5G network to U.S. customers from coast to coast!”

“This is an important day for our country and, most important, American consumers and businesses,” said Sprint Executive Chairman Marcelo Claure. “Today’s clearance from the DOJ, along with our anticipated approval from the FCC, will allow the U.S. to fiercely compete for 5G leadership. We plan to build one of the world’s most advanced 5G networks, which will massively revolutionize the way consumers and businesses use their connected devices to enhance their daily lives. The powerful combination of 5G, artificial intelligence and the Internet of Things will unleash endless possibilities.”
