SanDisk held an Investor Day unveiling a 2030 product blueprint and igniting rallies across memory and AI supply chain stocks.

Sandisk, the memory and storage chip giant, unveiled an ambitious long-term financial model and growth strategy at its Investor Day on August 13, projecting mid-to-high double-digit revenue growth, approximately 80% non-GAAP gross margin, and roughly 50% adjusted free cash flow margin by fiscal 2030. The company also committed to returning 100% of excess cash to shareholders after meeting operating needs. These announcements sparked a market-wide rally, with Sandisk shares surging more than 16% intraday and lifting the global memory and AI storage supply chain.

The cornerstone of Sandisk's strategy is a series of new business model agreements signed with eight customers, which lock in approximately 50% of bit supply for fiscal 2027 and roughly two-thirds for fiscal 2028. This unprecedented demand visibility marks a structural shift for the traditionally cyclical memory industry. Industry research firm TrendForce estimates these floor-price agreements have locked in a guaranteed revenue floor of at least $93.9 billion (approximately NT$3 trillion).

Under Sandisk's financial framework, revenue is expected to expand at a mid-to-high double-digit compound annual rate from fiscal 2028 through fiscal 2030, driven by continued bit shipment growth and structural demand from AI inference workloads requiring increased storage capacity. The company projects non-GAAP gross margin to remain near 80%, with non-GAAP operating margin reaching approximately 75% and operating expenses accounting for only about 5% of revenue.

Sandisk's forecast that enterprise data center flash memory demand will reach 1.2 zettabytes by 2030 emerged as the key catalyst igniting broader market enthusiasm. Market observers noted that if the long-term contract model scales across the industry, it could reduce the severe price volatility traditionally associated with memory chips, bringing earnings structures closer to those of logic chip and application-specific chip makers.

On the technology front, Sandisk is advancing BiCS9 QLC and BiCS10 QLC products. BiCS10 QLC delivers a 60% improvement in bit density over BiCS8, helping meet AI data center demand for higher storage density, performance, and power efficiency. Sandisk and Kioxia have commenced mass production of 10th-generation 3D flash memory at the Kitakami Fab2 facility in Japan.

The rally extended broadly across the supply chain. Western Digital surged 7.8% to close at $489.50 on strong investor focus regarding AI inference and cloud buildouts driving demand for high-capacity HDDs and the company's positioning in HAMR and UltraSMR technologies. Micron rose 6.64% to $971.82, with fiscal Q3 2026 revenue of $41.46 billion, adjusted EPS of $25.11, and gross margin of 84.9%. The company has signed 16 long-term partnership agreements with customers, further strengthening revenue visibility. South Korea's SK Hynix saw its U.S.-listed shares jump approximately 8%.

AI server and data center solutions provider Super Micro Computer gained 5.74% to close at $39.77, reporting fiscal Q4 2026 adjusted EPS of $1.70 and revenue of $11.1 billion. The company issued fiscal Q1 2027 revenue guidance of $14.5 billion to $15.5 billion, reflecting strong demand for servers and liquid cooling platforms.

Optical networking benefited significantly from AI data center interconnect demand. Ciena rose 5.45% to $455.58, with fiscal Q2 2026 revenue of $1.57 billion and backlog of $7.7 billion. The company raised full-year revenue guidance to approximately $6.3 billion. Marvell climbed 5.09% to $228.12, having raised its fiscal 2029 custom silicon revenue target to over $10 billion and projecting interconnect business growth of over 70% in fiscal 2027.

Seagate, the hard drive giant, gained 4.47% to $917.47 on strong demand for high-capacity nearline drives. The company reported fiscal Q4 2026 revenue of $3.6 billion and adjusted EPS of $5.71, with full-year free cash flow of $3.1 billion. HAMR technology and the Mozaic platform are accelerating in volume, with long-term contract visibility extending to 2028.

Semiconductor equipment and test companies also rallied. Lam Research rose 5.31% to $343.42, with sustained market focus on its exposure to etch and thin-film deposition equipment in memory and advanced process capacity expansions. Teradyne gained 4.2% to $419.67, recently added to the Nasdaq 100 index, benefiting from expanding semiconductor test equipment demand as AI chip complexity increases.

Intel rose 4.74% to $105.73, with market attention centered on its 18A and 14A process node progress, foundry business order momentum, and its planned $20 billion equity raise to fund AI-related initiatives and Ohio fab construction. Hewlett Packard Enterprise gained 4.15% to $61.23, reporting fiscal Q2 2026 revenue of $10.7 billion, up 40% year-over-year, with non-GAAP EPS of $0.79, and raised full-year EPS guidance to $3.35–$3.45 on elevated AI systems backlog.

However, structural headwinds remain. The United States' recent Section 301 tariffs on 60 global trading partners—covering Taiwan, South Korea, and other core semiconductor supply chain regions—could create long-term margin compression for U.S. hardware and semiconductor companies, adding uncertainty to the outlook despite the market's broadly optimistic sentiment.
