The Financial Post reports in its Tuesday, Sept. 2, edition that Dell Technologies shares fell after a decline in artificial intelligence server sales, booking $5.6-billion in orders for the fiscal second quarter, down from $12.1-billion previously (all figures U.S.). A Bloomberg dispatch to the Post reports that profit margins on these servers did not meet analysts' expectations. Despite strong demand for high-powered servers from companies like Dell and Super Micro Computer, concerns about profitability linger due to reliance on costly processors from Nvidia and AMD. Dell shipped $8.2-billion worth of AI servers and ended the quarter with an $11.7-billion backlog. Dell's infrastructure unit, which includes server and networking sales, reported an operating margin of 8.8 per cent, below analysts' expectations of 10.3 per cent. Overall, Dell's adjusted gross margin was 18.7 per cent, down from the previous year and short of the 19.6-per-cent estimate. The stock was up 16 per cent this year before the latest results were announced. Still, Dell boosted its annual outlook and posted quarterly sales and profit that topped analysts' estimates. Earnings will be about $9.55 a share in the fiscal year ending in January, an increase from a May forecast.
