Dell Technologies forecasted lower-than-expected fourth-quarter revenue and earnings, sending shares down 10% in after-hours trading. The company projected revenue below Wall Street estimates despite upbeat comments on AI sales growth. Dell's adjusted earnings per share exceeded expectations, while its revenue fell short of projections. The company reported higher net income and revenue compared to the same period last year. Dell leads in providing computer clusters for artificial intelligence development, particularly systems using Nvidia chips. It faces competition from Super Micro Computer, Hewlett Packard Enterprise, and Asian manufacturers.
