This notification concerns the following undertakings:

—	T-Mobile USA, Inc. (‘TMUS’, United States), controlled by Deutsche Telekom AG (Germany),

TMUS and OHC will acquire within the meaning of Article 3(1)(b) and 3(4) of the Merger Regulation joint control of Greenlight and GoNetSpeed, both previously ultimately controlled by OHC.

The concentration is accomplished by way of purchase of shares and assets (2).

The business activities of the undertakings concerned are the following:

—	TMUS is a wireless telecommunications company providing nation-wide coverage, voice, messaging and data services in the United States, Puerto Rico and the United States Virgin Islands,

The business activities of both Greenlight and GoNetSpeed are the following: provision of fibre-to-the-premises broadband serving primarily residential customers in the Northeastern United States.
