May 6 (Reuters) - Germany's Fresenius missed analysts' revenue expectations, hit by adverse currency exchange effects, as it reported first-quarter results on Wednesday.

The Hessian-based healthcare group reported quarterly revenue of 5.74 billion euros ($6.73 billion) before special effects, which was below analysts' average estimate of 5.81 billion euros in a Vara consensus poll.

Its operating profit before special effects was also below expectations at 678 million euros. Analysts were expecting 682 million euros on average.

Fresenius joins several other European companies that have been hit by unfavourable currency exchange rates, as translating the weak U.S. dollar to euros became more expensive.

The group confirmed its outlook for the 2026 financial year.
