Mike Sievert cut his last ties with T-Mobile US, resigning from the board and stepping down as vice chair a little over a year after he gave up the CEO job.

In a filing with the US Securities and Exchange Commission (SEC) Sievert (pictured) told the board he would resign from it and from its Transaction Committee on 1 November.

T-Mobile noted the resignation is not the result of any disagreement with the company over operations, policies or practices.

Recon Analytics founder and analyst Roger Entner noted on X Sievert’s exit echoes the departure of his predecessor John Legere years earlier.

The timing matches the expiry of an amendment to his employment agreement and made in September 2025 and completes a handover process begun when T-Mobile confirmed then COO Srini Gopalan would succeed Sievert as CEO.

A contract struck with Sievert in 2023 would have seen him remain CEO until 2028. He was appointed to the post in 2020 when T-Mobile closed its merger with Sprint.

He took on the vice chair post to stay involved in the management of the company and on the board.

Gopalan became T-Mobile’s COO in March 2025 after heading Deutsche Telekom’s German business.

He joined the US operator’s board in 2022.

Vodafone Group revealed its influential corporate affairs chief Joakim Reiter (pictured) is to depart at the end of the year, bringing the curtain down on a nine-year spell with the operator.

Reiter was instrumental in Vodafone’s push for fairer laws and regulations for the telecoms sector.

CEO Margherita Della Valle acknowledged Reiter’s impact, saying he argued the case for Vodafone with authorities “across Europe and Africa”.

She credited Reiter for making a “tremendous contribution” to Vodafone.

The executive is set to build on his campaigning work by becoming secretary general of the European Roundtable for Industry, a group established in 1983 to promote cooperation between businesses, governments and regulators.

Companies involved in the roundtable account for a combined €3 trillion in revenue per annum and make annual investments of €120 billion.

Vodafone stated it would announce a successor to Reiter “in due course”.

The European Roundtable for Industry is yet to detail what current secretary general Anthony Gooch Galvez’ plans are.
