FRANKFURT, May 3 (Reuters) - German healthcare group Fresenius on Wednesday toned up its earnings guidance for the year as demand for recently launched generic infusion drugs continued to grow at higher-than-expected rates.
For 2017, it now expects adjusted net income to grow by 19 to 21 percent, excluding the effect of currency swings, compared with a previous target for a 17 to 20 percent gain, to be shored up later this year by market launches of more than 10 products that have lost patent protection.
That excludes one-off charges of about 50 million euros expected from the last week's deals to acquire U.S. generic drugmaker Akorn Inc for $4.75 billion and the biosimilars arm of Germany's Merck KGaA and another 50 million euros in planned expenditures to build the Merck business later this year.
First-quarter adjusted net income jumped 28 percent to 457 million euros ($500 million), bolstered by recently launched drugs and the acquisition of Spanish hospital chain Quironsalud, coming in above the average estimate of 422 million euros in a Reuters poll of analysts.
The shares were seen 1.5 percent higher in pre-market trades ahead of the 0700 GMT market open, amid an overall German stock market that was indicated slightly lower.
Separately listed subsidiary Fresenius Medical Care , which derives about three quarters of sales from North America, posted a 17 percent gain in quarterly adjusted net income, benefiting from higher reimbursement rates and lower costs of medicines for dialysis patients.
First-quarter adjusted net income of 249 million euros excluded a one-off gain of 59 million euros from settling a dispute with the U.S. Departments of Veterans Affairs and Justice over outstanding payments.
