Seagate, Western Digital, and SanDisk report record earnings fueled by AI infrastructure growth
Category: Business
In a remarkable display of market resilience, memory and data storage stocks have surged in 2026, driven by an insatiable demand for high-capacity storage solutions in the artificial intelligence (AI) sector. Seagate Technology, Western Digital, and SanDisk have emerged as frontrunners in this booming market, posting impressive earnings that have captured the attention of investors.
Last Friday, all three major U.S. stock indexes—the tech-heavy Nasdaq, S&P 500, and Dow Jones Industrial Average—registered gains, with the Nasdaq leading the way up by 1.1%. This rally was bolstered by easing inflation concerns and expectations that the Federal Reserve may adopt a less aggressive stance on interest rates, allowing selective risk-taking across equities. Geopolitical developments, particularly around Iran, also influenced market sentiment, stabilizing oil prices and reducing inflation fears.
On May 4, 2026, Zacks Investment Ideas highlighted Micron Technology (MU), Alphabet (GOOGL), and SanDisk (SNDK) as red-hot tech stocks, underscoring the broader trend of rising interest in data storage solutions. Sandisk's stock has skyrocketed more than 3,000% since the beginning of the year, making it the top performer in the S&P 500 for 2026. Meanwhile, Western Digital and Seagate have doubled their stock values over the same period, placing them among the top ten stocks in the index.
Investors are eagerly anticipating upcoming earnings reports from these companies, which are expected to showcase strong results fueled by growing spending on AI hardware from major tech firms like Amazon, Microsoft, and Google. Analysts predict that these earnings could add to the momentum already seen in the market.
The AI boom is creating a storage crunch, as data centers require high-capacity hard disk drives (HDDs) to store, train, and manage vast AI datasets. According to Bank of America analyst Wamsi Mohan, hard disk drive supply remains tight, with manufacturers not adding unit capacity, which is viewed as a structural change in the market. This tight supply has allowed original equipment manufacturers (OEMs) to raise prices, benefiting companies like Seagate and Western Digital.
Seagate reported fiscal 2025 annual revenue of $9.10 billion, marking a 39% year-over-year increase. Its latest quarterly revenue on April 28 reached $3.11 billion, a 44% increase over the prior year, surpassing analyst expectations. Adjusted earnings per share (EPS) for Seagate hit $4.10, exceeding expectations of $3.50. Similarly, Western Digital's fiscal 2025 annual revenue reached $9.52 billion, up 51% year-over-year, with a recent quarterly revenue of $3.02 billion, a 25% jump that also exceeded Wall Street estimates.
The significance of these developments matters. Seagate and Western Digital are increasingly securing long-term contracts, shifting their business models from unpredictable hardware sales to a more stable, recurring demand strategy. This transition enhances revenue visibility and positions these companies favorably in a competitive market.
Both Seagate and Western Digital are benefiting from technological advancements, such as heat-assisted magnetic recording (HAMR), which allows for more data to be packed into the same-sized drive. This innovation reduces material costs, enabling companies to increase storage capacity without needing additional hardware.
In comparison, Micron, a leader in memory and storage solutions, particularly in the DRAM sector, is also experiencing a surge in demand. Micron's current fiscal year sales are expected to grow by 200% year-over-year, with earnings projected to increase by 600%. The company's broader product range, including NAND and HBM memory, provides it with a competitive edge over SanDisk, which relies heavily on NAND-based storage products.
As earnings reports are set to roll in, analysts will be closely monitoring the results from Seagate, Western Digital, and Sandisk, expected to reveal continued revenue and profit growth driven by booming demand and higher prices. Seagate is scheduled to report its earnings after the closing bell on Tuesday, with Western Digital and Sandisk following on Thursday afternoon.
Market analysts are optimistic, with Goldman Sachs stating that there is "fundamental upside for the entire memory/storage complex." They anticipate that strong earnings could provide additional momentum for the stocks, as the AI spending commitments from major tech firms are expected to continue driving demand for data storage solutions.
In the aftermath of these trends, investors are left to ponder the future of these companies. Will the demand for data storage continue to outpace supply, or will new competitors emerge as prices rise? With the current market dynamics, it seems likely that the memory and data storage sector will remain a hotbed of activity for the foreseeable future.
As of now, the market is buoyed by the anticipation of these earnings reports, with analysts from Bank of America predicting that all three companies will exceed Street estimates. The outlook for Seagate, Western Digital, and SanDisk is bright, and their performance may serve as a bellwether for the broader tech sector's health in the coming months.
