On September 26, 2017 Siemens and Alstom have signed a Memorandum of Understanding to combine Siemens' mobility business, including its rail traction drives business, with Alstom. The transaction brings together two innovative players of the railway market with unique customer value and operational potential. The two businesses are largely complementary in terms of activities and geographies. Siemens will receive newly issued shares in the combined company representing 50 percent of Alstom's share capital on a fully diluted basis.

On February 6, 2019 the European Commission has announced its decision to prohibit the proposed combination of the Siemens and Alstom mobility businesses. As a result of this prohibition, the merger will not proceed. Siemens and Alstom regret that the remedies they offered, including recent improvements, have been considered insufficient by the EU Commission.
