Citron Research released a short‑seller report on SanDisk Corporation on March 5 2026 at 09:14 UTC, alleging that the company’s narrative around AI‑driven memory growth is overstated and that its valuation is unsustainable.
The report’s thesis is that NAND flash memory is a commodity product in a cyclical market. Citron argues that the current tight supply is temporary and that a surge in supply from competitors such as Samsung could erode SanDisk’s pricing power and margins, citing historical cycles in 2008, 2012 and 2018 as evidence that the market behaves similarly each time.
SanDisk’s most recent quarterly results, released on January 29 2026, showed Non‑GAAP earnings per share of $6.20 and revenue of $3.03 billion, beating estimates by $2.66. Gross margin stood at 50.9%, driven by strong demand in edge computing, data‑center and consumer segments. The earnings beat was largely due to the company’s ability to maintain pricing power and operational leverage amid a favorable mix of high‑margin enterprise SSD deployments.
CEO David Goeckeler defended the company’s outlook, stating, "NAND is now recognized as indispensable to the world's storage needs, driving a foundational shift in how commercial relationships between suppliers and customers are structured." He added, "We continue to see customer demand well above supply beyond calendar year 2026," and noted, "This quarter's performance underscores our agility in capitalizing on better product mix, accelerating enterprise SSD deployments, and strengthening market demand dynamics, all at a time when the critical role that our products play in powering AI and the world's technology is being recognized."
Management’s guidance for the next quarter projects revenue of $4.4 billion to $4.8 billion and adjusted earnings per share of $12 to $14, with gross margin expected to rise to 65‑67%. The upward revision signals confidence in sustained demand and margin expansion, reinforcing the company’s belief that AI‑driven infrastructure demand represents a structural shift rather than a temporary cycle.
Investors reacted to Citron’s report by expressing concerns about valuation and the cyclical nature of NAND, while a broader sell‑off in memory stocks and geopolitical tensions added pressure. Western Digital’s sale of its remaining stake in SanDisk further amplified supply concerns. Despite the company’s strong earnings and optimistic outlook, market sentiment remained cautious, reflecting the tension between short‑seller allegations and management’s defense of a structural growth narrative.
