March 1 (Reuters) - Swiss logistics group Kuehne und Nagel reported a bigger-than-expected 49% drop in annual operating profit on Friday, citing weaker performance across nearly all its segments in a challenging environment.

Its earnings before interest and taxes fell to 1.90 billion Swiss francs ($2.15 billion) last year, from 3.76 billion in 2022, missing analysts' forecast of 2.01 billion in a company-provided poll.
