(Reuters) - Super Micro Computer shares tumbled 12.3% in premarket trading on Wednesday as concerns over the high cost of producing AI server chips weighing on its profit forecast, eclipsing upbeat sales forecasts.
The company's fourth-quarter adjusted gross margin was 11.3%, compared with analysts' average estimate of 14.1%, according to LSEG data, as Super Micro grappled with higher supply chain costs and a tight inventory of key components.
