Siemens AG made an announcement that it plans to spin off its healthcare division with a value of $15 billion to help boost investments in one of its units that is most successful, in one of the largest portfolio revamps at the engineering giant based in Germany that narrows the company focus on factory gear, transport and energy.

The company will pursue a public listing for the asset, with all details on its planned scope and when it will be completed to follow.

Profit from its industrial operations was €2.45 billion equal to $2.68 billion for the three months that ended September 30, with little change when compared to the same period one year ago. Analysts were expecting €2.41 billion.

Joe Kaeser the CEO at Siemens said that healthcare was an attractive business and possibly the most attractive the company has.

Siemens has bet that its healthcare unit will capture growth at a better rate when being a stand-alone company, though Siemens would look to retain the control of said asset.

CEO Kaeser has shifted the company more toward the energy divisions it has, which includes its business of wind-turbines and the CEO has said he does not expect there to be demand swings across that field following the election of Donald Trump to the White House.

Siemens stock was up over 2.9% in Frankfurt trading on Thursday. The stock has increased by 19% since the start of 2016 making it the DAX Index’s third best performer for that period.

Plans to list the healthcare unit whittles down even further the sprawling portfolio of the company that includes wind turbines, high-speed trains as well as medical scanners.

Over the last decade, the company has retreated in a large way from products that are consumer oriented and has focused on its industrial applications, selling things such as light bulbs, phones and hearing aids.

Amongst the largest divestments recently at Siemens was its lighting unit Osram, though the CEO said it was not correct to compare that asset with healthcare.

Sales during the fourth quarter were up 3% to just over €21.90 billon, while orders were down 14% following the receiving of large orders during the same period one year ago.

The gas and power division led its growth in sales with an increase of 10%, while its process industry and drives were the only ones that reported a drop in sales.
