SANTA CLARA, Calif.--(BUSINESS WIRE)--Intel Corporation today announced that first-quarter revenue is expected to be below the company's previous outlook. The company now expects first-quarter revenue to be $12.8 billion, plus or minus $300 million, compared to the previous expectation of $13.7 billion, plus or minus $500 million. The change in revenue outlook is a result of weaker than expected demand for business desktop PCs and lower than expected inventory levels across the PC supply chain.
