INTRODUCTORY NOTE

On April 1, 2020, T-Mobile US, Inc., a Delaware corporation (“T-Mobile”), and Sprint Corporation, a Delaware corporation (“Sprint,” collectively with T-Mobile, the “Sellers”), completed the previously announced business combination (the “Merger”) between T-Mobile and Sprint pursuant to the Business Combination Agreement, dated as of April 29, 2018, as amended, by and among T-Mobile, Sprint, and the other parties thereto. As a result of the Merger, Sprint became an indirect wholly-owned subsidiary of T-Mobile.

On July 1, 2020, T-Mobile and Sprint completed the previously announced divestiture of Sprint’s prepaid wireless business to DISH Network Corporation, a Nevada corporation (“DISH”), pursuant to the terms and conditions of the Asset Purchase Agreement, dated as of July 26, 2019 (as amended, the “Asset Purchase Agreement”). Pursuant to the terms of the Asset Purchase Agreement, DISH acquired Sprint’s prepaid wireless business, which was historically operated by Sprint under the Boost Mobile, Virgin Mobile and Sprint prepaid brands, including customer accounts, inventory, contracts, intellectual property and certain other specified assets (but excluding the Assurance brand Lifeline customers and the prepaid wireless customers of Shenandoah Telecommunications Company and Swiftel Communications, Inc.), and assumed certain related liabilities (collectively, the “Prepaid Business Sale”).

On July 1, 2020, in connection with the closing of the Prepaid Business Sale, the Sellers and DISH entered into a Master Network Services Agreement (the “MNSA”). Pursuant to the terms of the MNSA, DISH would receive network services from T-Mobile for a period of seven years, including (i) legacy network services for certain Boost Mobile prepaid end users on the Sprint network, (ii) T-Mobile network services for certain end users that have been migrated to the T-Mobile network or provisioned on the T-Mobile network by or on behalf of DISH, and (iii) infrastructure mobile network operator services to assist in the access and integration of the DISH network.

Item 1.01 - Entry into a Material Definitive Agreement

In addition to binding the Parties to certain material modifications of the overall commercial relationship, the Term Sheet requires T-Mobile and DISH to negotiate in good faith an amendment to the MNSA and any other necessary agreements in order to further effectuate such modifications. These modifications include, as described further below, certain bilateral roaming arrangements and restrictions, commitments relating to the migration of customers off of Sprint’s legacy code division multiple access wireless network technology (“CDMA”) network, changes to DISH’s pricing and available discounts, and the addition of DISH minimum purchase commitments. Until such time as the definitive agreements are entered into (and whether or not any such definitive agreements are ever finalized, executed, and entered into), the Term Sheet, and all of the obligations contained within the Term Sheet, shall remain in full force and effect and binding upon the parties (subject to the DOJ approval noted above).

Item 7.01 – Regulation FD Disclosure

On June 21, 2022, T-Mobile and DISH issued a joint press release in connection with the announcement of the execution of the Term Sheet. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference. The information furnished pursuant to this Item 7.01, including Exhibit 99.1, will not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as may be expressly set forth by specific reference in such a filing.

Cautionary Statement Regarding Forward-Looking Statements

This communication contains certain forward-looking statements concerning T-Mobile, DISH and the proposed transactions (subject to DOJ approval) between T-Mobile and DISH. All statements other than statements of fact, including information concerning future results, are forward-looking statements. These forward-looking statements are generally identified by the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “could” or similar expressions. Such forward-looking statements include, but are not limited to, statements about the benefits of the proposed transactions, including anticipated future financial and operating results, T-Mobile’s objectives, expectations and intentions, and the expected timing of completion of the proposed transactions. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements. Such factors include, but are not limited to, the risk that the DOJ withdraws, retracts or modifies its approval in a manner that adversely affects T-Mobile or the expected benefits of the proposed transactions with

DISH or does not approve the Term Sheet in a timely manner or at all; the failure to satisfy any of the conditions to the proposed transactions on a timely basis or at all; the occurrence of events that may give rise to a right of one or both of the parties to terminate the Term Sheet or definitive agreements; adverse effects on the market price of T-Mobile’s common stock and on T-Mobile’s operating results because of a failure to complete the proposed transactions in the anticipated timeframe or at all; negative effects of the announcement, pendency or consummation of the proposed transactions on the market price of T-Mobile’s common stock and on T-Mobile’s operating results, including as a result of changes in key customer, supplier, employee or other business relationships; the risk of litigation or regulatory actions; and other risks and uncertainties detailed in T-Mobile’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, including in the sections thereof captioned “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements,” as well as in its subsequent reports on Form 8-K and Form 10-Q, all of which are filed with the SEC and available at www.sec.gov and www.t-mobile.com. Forward-looking statements are based on current expectations and assumptions, which are subject to risks and uncertainties that may cause actual results to differ materially from those expressed in or implied by such forward-looking statements. Given these risks and uncertainties, persons reading this communication are cautioned not to place undue reliance on such forward-looking statements.
