In the past six months (March 2026 - September 2026), SanDisk shares experienced substantial gains, advancing 695% in 2026 and over 1,700% in the past year, making it the best-performing stock in the S&P 500 in both 2025 and 2026, largely due to the AI boom and a severe memory chip shortage. In April 2026, shares rallied following an analyst upgrade and Nasdaq-100 inclusion. Western Digital continued to dispose of its remaining equity stake in May 2026. In July 2026, SanDisk reported strong Q4 fiscal 2026 results with revenue surging 372% to $8.97 billion, driven by data center revenue more than doubling, though the stock fell 13.3% due to high market expectations and a slightly below-forecast revenue outlook. August 2026 saw the board approve a $14 billion share repurchase program and announce a joint investment with Kioxia of over $31 billion in Japan through 2032, including a new fab. In September 2026, SanDisk entered the S&P 100 and experienced a rally, possibly driven by increasing demand for data storage solutions in AI, but also saw a pullback of 18-33% from its June peak due to profit-taking and concerns about future AI-related memory demand. SanDisk has also signed multiple strategic multi-year supply agreements to improve demand visibility and reduce cyclicality, covering roughly two-thirds of fiscal 2028 bit supply.
