Singapore – German dialysis specialist, Fresenius Medical Care has agreed to sell its controlling interest in Sound Inpatient Physicians Holdings to an investment consortium led by Summit Partners for $2.15B.

The deal, expected to close in late 2018, will bring a pretax book gain of about €800M.

Fresenius has also decided to pull out of its planned $4.75B acquisition of Akorn after it found data integrity breaches at the drugmaker.
