US conglomerate General Electric has offered concessions in an attempt to counter EU regulatory concerns about its €12.4 billion bid for French peer Alstom’s power unit, its biggest ever acquisition.

The company submitted its proposal on Thursday but did not provide details.

“GE confirms it has submitted remedies to the European Commission in relation to the GE-Alstom transaction.

“These remedies add­ress the concerns of the Commission and at the same time preserve the economic and strategic value of the deal,” the company said in a statement.

The concessions will have to address the European Commission’s worries that the deal could hurt competition as it would result in the merged gas turbine company competing with only German rival Siemens.

The EU competition authority is likely to extend its scrutiny to mid-September from August 21 as it seeks feedback from rivals such as Siemens, Mitsubishi Hitachi Power Systems, Toshiba Corp, Italian company Ansaldo and customers.

Selling off some of Alstom’s intellectual property or physical equipment lines would be considered limited concessions to win EU approval, Sanford Bernstein analyst Steven Winoker said in a research note last month.

GE has drawn the line against divesting anything that would hurt business gained from servicing gas turbines, which generate lucrative revenues.
