T-Mobile executives oppose $300B Deutsche Telekom merger plan - report
According to Semafor, T-Mobile US executives told Deutsche Telekom they no longer support a proposed $300 billion merger. They cited shareholder concerns and likely US regulatory requirements, including a guarantee that T-Mobile’s US revenue would be reinvested or kept in the country. T-Mobile shares were down about 0.9% and Deutsche Telekom ADRs about 0.9% lower.
