Shares of F5 Inc. /zigman2/quotes/209237881/composite FFIV -0.87% fell more than 17% in the extended session Tuesday after the software company reported quarterly earnings and sales above Wall Street expectations but said supply-chain snags are crimping its ability to meet increased demand. F5 said it earned $94 million, or $1.51 a share, in the fiscal first quarter, compared with $88 million, or $1.41 a share, in the year-ago quarter. Adjusted for one-time items, F5 earned $2.89 a share, compared with $2.59 a share a year ago. Sales rose 10% to $687 million, the company said. Factset consensus called for an adjusted EPS of $2.78 a share on sales of $678 million. There was "strong demand" for F5's application security and delivery products, Chief Executive Francois Locoh-Donou said in a statement. While that demand "remains robust, the company expects that its ability to meet customers' continued strong demand for systems will be restricted by supply-chain constraints for the remainder of fiscal year 2022." As a result, the company called for fiscal second-quarter revenue between $610 million and $650 million. The analysts surveyed by FactSet expect sales of $693 million for the quarter. For fiscal 2022, F5 expects revenue growth between 4.5% and 8%, down from a prior expectation of 8% to 9% growth. The company expects fiscal 2022 software revenue growth "near the top end" of a previously provided 35% to 40% guidance range, and fiscal 2022 global services revenue growth of 1% to 2%, it said. F5 ended the regular trading day down 2.4%.
