Seagate's 34% Revenue Growth: Can STX Keep It Up?
💡 Key Takeaway
Seagate's 34% revenue growth and strong fiscal 2027 guidance signal that AI-driven storage demand remains robust, making STX a compelling buy despite its massive run-up.
Seagate's Blockbuster Growth and What's Driving It
Seagate Technology (STX) just reported fiscal 2026 revenue growth of 34%, a standout performance for a company many had written off as a slow-growth hardware maker. The surge was fueled by cloud and data center demand, with a stunning 90% of its exabyte shipments going to data centers. That's not a typo: nine out of every ten bytes Seagate shipped went to power the cloud.
The company also made significant progress with its HAMR (Heat-Assisted Magnetic Recording) technology, which now accounts for 40% of its nearline run rate. HAMR allows for higher storage densities, meaning Seagate can pack more data onto each drive. This is crucial as AI models and cloud services generate explosive amounts of data that need to be stored somewhere.
Management didn't stop at celebrating the past year. They guided for fiscal 2027 revenue growth to exceed fiscal 2026's 34% pace. That's a bold call, but it's backed by the ongoing AI infrastructure buildout and Seagate's improving product mix. The stock has responded in kind, rocketing 343.9% over the past year and earning a Zacks Rank #1 (Strong Buy).
For context, this isn't just a Seagate story. Rival Western Digital (WDC) saw fiscal 2026 revenues jump 36%, with its cloud segment generating 89% of quarterly revenues. And memory specialist Micron (MU) posted record results, benefiting from the same AI-driven demand for storage and memory. The entire storage sector is firing on all cylinders.
Why Seagate's Guidance Matters for Investors
Seagate's guidance for fiscal 2027 is the real headline here. When a company growing at 34% says it will grow even faster next year, investors pay attention. It signals that the AI data boom isn't slowing down—it's accelerating. For Seagate, that means more high-margin nearline drives sold to cloud giants like Amazon, Microsoft, and Google.
The shift to HAMR technology is also a big deal. HAMR drives are more expensive and carry higher margins, so as they become a larger portion of Seagate's mix, profitability should improve. The fact that HAMR is already at 40% of nearline run rate shows adoption is happening quickly, which bodes well for future earnings.
However, the stock's 343.9% gain over the past year means a lot of good news is already priced in. Seagate now trades at a premium valuation, and any hiccup in cloud spending or a delay in HAMR ramp-up could lead to a sharp pullback. The law of large numbers also makes sustaining 34% growth harder as the revenue base grows.
Still, the broader storage demand picture is undeniably strong. Western Digital's 45% year-over-year growth guidance for the current quarter and Micron's record results confirm that this is an industry-wide upcycle, not a Seagate-specific fluke. As long as AI and cloud spending remain robust, storage stocks should continue to benefit.

Buy STX on any pullback, as the AI storage supercycle is far from over and Seagate's HAMR ramp will drive margin expansion.
Seagate's 34% growth and upbeat fiscal 2027 guidance show that demand for high-capacity storage is not slowing. The shift to HAMR technology should boost profitability, and the stock's momentum is backed by strong industry fundamentals. While valuation is stretched, the growth trajectory justifies a premium.
