AI Memory Boom Boosts Micron, SanDisk Outlook
AI memory boom lifts Micron and SanDisk as SanDisk Investor Day and a Bank of America research scenario prompted trader positioning and cyclicality debate.
KEY TAKEAWAYS
- Bank of America modeled Micron EPS near $236 by fiscal 2030 under an AI HBM tightness scenario.
- SanDisk guided mid-to-high-teens annual revenue growth and aggressive margin targets for FY2028-FY2030.
- Some institutions trimmed Micron and exited SanDisk, illustrating profit-taking amid the rally.

Micron Technology and SanDisk attracted investor attention this week as the AI memory boom accelerated, driven by Intel CEO Lip-Bu Tan’s Aug. 12 remarks on new memory architectures and SanDisk’s Aug. 13 Investor Day. The developments prompted bullish analyst scenarios alongside some institutional repositioning.
Micron Earnings Outlook and HBM Market Growth
Bank of America projected that Micron’s earnings per share could reach about $236 by fiscal 2030, implying a 34.1% annual EPS compound growth rate compared with a consensus near $136. The firm tied this upside to sustained AI-driven demand for high-bandwidth memory (HBM) and ongoing supply tightness.
The research highlighted a 343% year-over-year surge in Micron’s HBM-related DRAM revenue and noted that HBM consumes roughly three times the wafer capacity per bit, which constrains supply and supports elevated pricing. The report models the global HBM market expanding from about $35 billion in 2025 to roughly $100 billion by 2028, reflecting a near 40% compound annual growth rate.
Bank of America emphasized that the memory industry has historically experienced sharp boom-and-bust cycles, cautioning investors against assuming current conditions will persist indefinitely.
SanDisk Investor Day Targets and AI Storage Demand
On Aug. 13, SanDisk presented a financial framework for fiscal years 2028 to 2030 tied to AI infrastructure demand. The company guided to mid-to-high-teens annual revenue growth, roughly aligned with bit-shipment expansion, the industry term for physical storage capacity produced.
SanDisk set long-term targets of about 80% non-GAAP gross margin, roughly 75% non-GAAP operating margin, and approximately 50% adjusted free-cash-flow margin. It also committed to returning 100% of excess cash after funding operations and investments. Management linked these forecasts to “New Business Model” agreements with about eight customers expected to account for roughly two-thirds of bits shipped by fiscal 2028. The company cited enterprise data-center flash demand of about 1.2 zettabytes by 2030.
Coverage characterized the guidance as unusually aggressive for the NAND segment and a sector-wide catalyst, noting that achieving these margins depends on execution and sustained AI demand.
Intel Memory Architecture Initiatives and Investor Positioning
Intel CEO Lip-Bu Tan discussed exploring new memory architectures and closer CPU-memory integration on the TechSurge podcast, describing the effort as a strategic research and development focus rather than an announced product lineup. He said he had previously viewed memory as a commodity but now believes “the economics have changed,” calling new memory architectures one of his “pet projects.”
Technical reports identified two architectural efforts: Cross-Batch Memory (XBM), which aims to deliver HBM4-like bandwidth without a silicon interposer by using UCIe connections and back-end-of-line thin-film transistors, and Z-Angle Memory (ZAM), a stacked DRAM co-developed with SoftBank’s SAIMEMORY targeting higher bandwidth density and lower power consumption. An XBM patent was filed Dec. 26, 2024, and published Jul. 2, 2026, while ZAM prototypes are targeted for 2027 with potential commercialization in 2029–2030. These timelines represent technology roadmaps rather than revenue forecasts.
Intel has not disclosed a standalone memory business unit or earnings cadence tied to these projects and said it is “not ready to unfold” full plans.
Meanwhile, a Q2 2026 13F filing by Appaloosa Management showed the fund trimmed Micron and exited SanDisk, illustrating institutional repositioning amid the rally. Coverage framed this as profit-taking and redeployment into other AI-stack exposures.
The market debate centers on whether AI-driven memory demand represents a structural step change or a cyclical surge. Analyst scenarios and SanDisk’s targets have fueled sector optimism, while some institutional filings and the industry’s history of abrupt capacity swings provide countervailing signals.
