Siemens AG is close to naming a venue for the stockmarket listing of its Healthineers medical equipment arm, with Frankfurt now favored for the listing which could value the company at 40 billion euros ($47.5 billion).

Siemens is expected to float 15-25 percent of Healthineers, which makes X-ray and MRI machines, by March of next year, sources have said. That implies stock worth 6-10 billion euros could be put up for sale.

If Frankfurt gets the listing rather than New York or London, both considered by Siemens because of their deep capital markets, it would make the share sale Germany’s largest since the sales of state shares in Deutsche Telekom  around the turn of the millennium.

The German industrial conglomerate which is seeking to simplify its structure has already appointed Goldman Sachs Deutsche Bank and JP Morgan as lead organizers of the Healthineers IPO.
