(Reuters) -Cisco Systems said on Wednesday that its finance chief Scott Herren will retire from the company in July, and raised its annual results forecast, betting on steady demand from cloud customers for its networking equipment, driven by the artificial intelligence boom. Herren will be replaced by Mark Patterson, currently Cisco's chief strategy officer, who will start as the CFO on July 27. With products such as ethernet switches and routers, Cisco has benefited from a boom in data center investment, as technology giants have ramped up capital expenditure to meet the computing power needed to run generative AI applications.
