Siemens has had success with the spinoff model in the past. In 2018, it spun off its profitable healthcare business as Siemens Healthineers, but retained an 85% stake in the company. For its power spinoff, though, it's planning to only retain a 25% to 50% stake. Many details of the spinoff are still unknown, but Siemens could clean up its balance sheet by spinning off some of its more than $40 billion in debt along with the underperforming turbine business, to the benefit of the parent company.
