(RTTNews) - Fresenius Medical Care AG & Co. KGaA (FMS) reported that its fourth quarter net income attributable to shareholders of the company increased 29% year-over-year to 229 million euros, while quarterly net income was up 23% at constant currency. These effects were only slightly mitigated by an improved U.S. payor mix, in particular due to an increased number of patients with Medicare Advantage coverage. The company targets to return to earnings growth this year, despite the ongoing impact of the pandemic and an increasingly inflationary cost environment.
