How Deutsche Telekom and T-Mobile US could pull off the world’s biggest M&A deal

LONDON/BERLIN: Deutsche Telekom is exploring a possible tie-up with T-Mobile US to create a $300 billion telecoms giant, sources said, in what would overtake Vodafone-Mannesmann’s $203 billion merger in 1999 to become the biggest M&A deal ever.

The German group already controls 53% of the U.S. unit. But a deal would potentially bring both companies under one entity in a bid to reignite growth in a stagnating telecoms sector, according to a person familiar with the situation and Bloomberg, which was first to report the talks on Wednesday.
