Semiconductor and storage firms face market shifts amid AI demand

The semiconductor and storage sectors are experiencing significant shifts driven by artificial intelligence demand and changing competitive landscapes. Sandisk has seen massive growth since its February 2025 spinoff, with its stock rising over 4,700% and revenue reaching $20.2 billion in fiscal 2026. This rapid appreciation has led to speculation regarding a potential stock split due to its high nominal share price.

Western Digital is also seeing strong performance, with sales rising 44% to $3.8 billion in its fourth quarter of fiscal 2026. However, the company recently faced an 11.7% stock decline following reports that Toshiba plans to double its hard-drive production capacity. Such an expansion could potentially increase Toshiba’s market share from 17% to 30%, challenging the dominance of Western Digital and Seagate Technology.

Meanwhile, Micron has reported strong fiscal 2026 results, with revenue reaching $133 billion. Despite exceeding expectations, investors remain cautious due to the cyclical nature of the memory industry. While Micron benefits from high demand for DRAM and high-bandwidth memory (HBM) through partnerships with Nvidia, analysts warn of a potential downturn in fiscal 2028 as the industry cycle shifts.
