SanDisk Extends AI Storage Rally as Memory Cycle Risks Persist

SanDisk Corporation has emerged as a major beneficiary of artificial intelligence infrastructure spending, with its shares climbing sharply in 2026 as demand for NAND flash memory supports higher revenue and profit margins. Analysts have raised their price targets on expectations that AI data centers will sustain storage demand, although historical industry cycles and the prospect of falling memory prices present risks to the rally.

TradingView reported on October 11 that SanDisk shares had gained 575% in 2026 and recovered nearly 60% from their July low, reaching approximately $1,600. The company's performance reflects growing demand for high-capacity storage as AI systems expand beyond model training toward large-scale inference and other computing workloads.

Analyst forecasts have continued to rise. Mizuho recently increased its price target to $2,050 from $1,875, citing demand associated with agentic AI. Rosenblatt set a $2,400 target in late September, while Arete Research established a $3,000 target in August, according to TradingView.

Separately, The Globe and Mail reported that SanDisk's median analyst price target was $2,225, compared with a share price of $1,660 at the time of its report on October 7. That target implied approximately 34% upside. The publication also reported that Micron Technology had gained 460% over the preceding year, while SanDisk had risen 1,190% over the same period.

SanDisk's financial results show the scale of the recent expansion. According to Yahoo Finance's October 9 analysis, revenue over the trailing 12 months reached $20.2 billion, compared with $7.4 billion a year earlier. Its adjusted operating margin increased to 61.6% from 6.9%, while its generally accepted accounting principles operating margin improved to 61.2% from negative 18.7%.

Operating cash flow represented 57.6% of revenue over the trailing 12 months. SanDisk traded at approximately 21.8 times earnings on October 7, close to the S&P 500's multiple of 21.5, according to Yahoo Finance. However, the company's earnings had changed substantially from the previous year, complicating comparisons based on valuation multiples.

Management's August 5 fiscal fourth-quarter 2026 earnings call highlighted the role of pricing in the expansion. Higher prices accounted for approximately two-thirds of sequential revenue growth, while increased sales volume contributed the remainder. That dependence creates exposure if memory prices weaken as manufacturers expand supply.

The broader semiconductor industry provides a warning. The Globe and Mail reported that NAND and dynamic random access memory prices had increased 70% and 160%, respectively, since January 2025, despite retreating from earlier peaks. During the previous downturn, prices for both memory types fell approximately 70% between early 2021 and late 2023.

That earlier decline coincided with substantial losses for memory-related stocks. Micron shares fell 50%, while Western Digital, SanDisk's former parent company, declined 60%. Those losses occurred even though Micron and Western Digital traded at approximately 12 and 14 times adjusted earnings, respectively, after reporting fiscal 2021 results.

Analysts supporting the current bullish outlook point to structural changes in storage demand. TradingView reported that SanDisk is pursuing longer-term customer contracts that establish volume commitments and price floors, while directing more production toward enterprise customers and data centers. These arrangements could improve revenue visibility compared with dependence on short-term memory pricing, although they do not eliminate exposure to market fluctuations.

Supply growth remains another concern. Increased production by competitors, including Chinese manufacturers, could create excess inventory and pressure prices. Consumer electronics demand also remains a potential source of weakness, while lower memory prices could reduce earnings before those changes appear fully in financial statements.

Yahoo Finance also reported that SanDisk shares had experienced two declines of at least 20% within 30 trading days since 2025. Following the April 7, 2025, decline of 35%, the shares eventually gained approximately 2,158% over the following year and reached a peak return of about 2,926% after 371 days. The July 17, 2026, decline of 26% remains too recent for a comparable one-year assessment, and the shares subsequently experienced a further maximum drop of 25% during the period analyzed.

SanDisk's next earnings report, expected at the end of October, is likely to provide updated information on pricing, customer contracts, demand from AI infrastructure and the durability of its elevated margins.
