SanDisk designs solid-state storage products based on flash memory, a non-volatile technology that preserves data without power. Its offerings include memory cards (CompactFlash, SD) and USB flash drives, using controllers and firmware to manage read/write, error correction, and wear leveling for durable, portable storage. The company helped popularize flash memory for cameras and mobile devices and expanded production to meet growing demand. In 2016, Western Digital acquired SanDisk for about $19 billion, combining flash expertise with HDD leadership to provide a broader range of storage solutions.

SanDisk soars 12% to $273B market cap before joining S&P 100

Sandisk Corporation joined the S&P 100 index on 21 September following an 11.9% surge that lifted its share price to $1,740 and pushed market capitalisation to approximately $273 billion. The flash-memory company's latest quarterly results showed revenue climbing 372% to $8.97 billion, whilst gross margin expanded to 84.6%. Data-centre revenue more than doubled sequentially to $2.98 billion. Management increased its share-repurchase authorisation to $15.5 billion and projected revenue of up to $10.8 billion for the coming quarter. The repurchase capacity represents roughly 5.7% of Sandisk's market capitalisation, whilst S&P 100 admission could trigger additional index-fund demand.

Micron and SanDisk jump 5-8% on memory shortage despite strong jobs report flipping Fed hike odds above 50%

Micron Technology and SanDisk shares jumped 5% and 8% respectively on Friday, despite a strong US jobs report that briefly pushed Federal Reserve rate hike odds above 50%. The US economy added 162,000 jobs in August, nearly triple expectations, sending Treasury yields higher and pressuring broader markets. The memory chip makers outperformed as semiconductor shortages continued to drive prices higher. Susquehanna expects DRAM contract prices to rise over 50% this quarter, whilst NAND prices could climb about 60%. Dell's COO highlighted persistent supply constraints across DRAM and NAND chips during the company's earnings call. The rally contrasted with rate-sensitive sectors like gold miners, which fell 1.9%, underscoring unusual strength in memory stocks despite hawkish market repricing.

Sandisk revenue surges 371% on AI demand as Qualcomm faces handset market headwinds

Sandisk reported 371% year-over-year revenue growth in its recent quarter, driven by AI demand and a strategic shift to long-term customer agreements. The flash memory storage company posted a 78% operating margin for the quarter ended 3 July 2026. In contrast, Qualcomm is experiencing gradual revenue decline despite its strong position in wireless communication technologies. The company recorded a 17% operating margin for the quarter ended 28 June 2026. Sandisk's transformation over the past 18 months moved it away from quarterly price negotiations towards long-term contracts, reducing business cyclicality whilst improving revenue visibility. Qualcomm is transitioning to serve the data centre market, where its wireless connectivity expertise could drive future growth and potentially reverse its current revenue trend.

SanDisk and Kioxia commit $31B to NAND expansion backed by $91B in contracted demand

SanDisk and Japanese partner Kioxia announced plans to invest over $31 billion in Japan over six years to expand NAND flash capacity for AI applications. The investment includes roughly $11.3 billion for a new facility at Kioxia's Kitakami plant to produce tenth-generation BiCS Flash. SanDisk shares closed at $1,484.98 on Friday, up 526% year to date. The company has signed new business model agreements with eight data centre and edge customers, with a weighted average duration of over four years. CEO David Goeckeler said revenue visibility stretched from three months a year ago to over four years. The backlog includes $91.1 billion in remaining performance obligations, backed by $16.5 billion in customer financial guarantees. Fiscal fourth-quarter revenue reached $8.96 billion, up 372% year over year.

SanDisk lays off dozens in Israel R&D centres despite 2,809% stock surge and $8.96B revenue

SanDisk has laid off dozens of R&D employees at its Israeli development centres in Kfar Saba, Tefen, and Omer, according to reports. The sites employ approximately 700 people. The cuts come as SanDisk experiences exceptional growth, with shares up 2,809% over the past year. The flash-memory maker reported fiscal Q4 revenue of $8.96 billion, up 372% year-over-year, whilst EPS of $38.82 exceeded Wall Street's $33.28 estimate. Data centre revenue more than doubled from the prior quarter to $2.98 billion. SanDisk expects up to $10.8 billion in revenue this quarter and is targeting roughly 80% gross margins through fiscal 2030. The layoffs appear part of a cost-efficiency initiative, as GAAP operating expenses fell 1% from the prior quarter to $545 million.
