Germany’s antitrust regulator has extended the review of IBM’s $962 million acquisition of T-Systems to July 9.

According to a statement placed on the website of Germany’s antitrust office, it is extending its review of a mainframe computing deal between the IT services arm of Deutsche Telekom, T-Systems, and IBM.

The review period is being extended by two weeks to July 9, said the Federal Cartel Office in its update of the deal which sees IBM acquiring the assets of T-Systems.

The two firms have declined to comment in detail on the mainframe alliance which was announced in January. At that time reports stated IBM would pay $962 million (860 million euros) for the business which has an employee strength of 400.

Adel Al-Saleh, T-Systems’ CEO had drafted plans to turn around the company at the beginning of 2018. He has cut staff, closed offices and outsourced some jobs to try and generate sustainable profits and cash flows.

Neither T-Systems nor IBM responded to requests for comments.
