Cisco shares rose as much as 5% in extended trading on Wednesday after the enterprise software and hardware maker disclosed fiscal second-quarter earnings that surpassed analysts' expectations. Here's how the company did: Earnings: 84 cents per share, adjusted, vs. 81 cents per share as expected by analysts, according to Refinitiv. Revenue: $12.70 billion, vs. $12.65 billion as expected by analysts, according to Refinitiv. Revenue increased by 6% year over year in the quarter, which ended Jan. 29, according to a statement. In the previous quarter revenue had risen 8%. "There are still significant constraints with semiconductors, preventing us from completing manufacturing of some of our products, and that remains a headwind to revenue growth despite very strong demand," Cisco CEO Chuck Robbins said on a conference call with analysts. He said he isn't sure when components would become more readily available.
