NEW YORK, Feb 1 (Reuters) - Shares of C.H. Robinson Worldwide stock tumbled by 14% on Thursday after weak freight demand combined with disruptions arising from the Red Sea crisis caused the U.S. freight and logistics giant's fourth quarter results to miss analyst estimates.

C.H. Robinson's revenue fell about 17% to $4.2 billion in the quarter ended Dec. 31, while adjusted earnings per share fell 51% to 50 cents dragged down by poor demand and falling prices from excess freight capacity, the company reported late on Wednesday. Wall Street analysts had expected revenue of $4.34 billion and earnings per share of 81 cents, according to LSEG data. C.H. Robinson shares dropped to as low as $72.29, the lowest since May 2020, and were on track for their biggest daily percent decline since October 2019.

"Our fourth quarter results did not meet our expectations as we continue to battle through a poor demand and pricing environment," said C.H. Robinson Chief Executive Dave Bozeman during an analyst conference call on Wednesday.

Attacks by Yemen's Iran-aligned Houthi group on vessels in the Red Sea, launched to express solidarity with Palestinians in Gaza, have forced shippers like C.H. Robinson to take longer routes that can add weeks to delivery times.

"While the Red Sea disruption continues without any clear time line of when it will be resolved, the strain on capacity and the elevated spot rates are expected to continue through at least the Chinese New Year," Bozeman said.
