Nokia Oyj will replace Chief Executive Officer Pekka Lundmark with Intel Corp.’s recently appointed head of artificial intelligence Justin Hotard in a surprise announcement as the network equipment maker works to exit a prolonged slump in orders from phone operators.

Justin Hotard, Intel’s head of data-center and AI operations, is leaving to head up Nokia. Shares of the telecom-gear maker rallied over 2% in Europe; U.S.-listed Intel shares edged higher premarket.

Nokia has announced that CEO Pekka Lundmark will step down. He took up the position in 2020. He will be replaced by Justin Hotard, who is currently Intel’s Chief Data Center Officer and has previously held executive positions at technology companies such as Hewlett Packard Enterprise and NCR Corporation.
