Seagate Technology (NASDAQ:STX | STX Price Prediction) reports fiscal Q4 2026 results tonight at 4:05 PM ET. With shares up 445.89% over the past year, but down 8.28% today, the earnings report will test whether HAMR execution and cloud demand can justify a $170 billion market cap.
Momentum Meets a Higher Bar
Last quarter reset expectations. Seagate delivered $3.1 billion in revenue, up 44% year-over-year, with non-GAAP gross margin expanding to 47% from 36.2% a year earlier. Free cash flow reached $953 million, the highest in over a decade.
CEO Dave Mosley raised the multi-year revenue growth target from “low- to mid-teens to a minimum of 20% over the next few years,” citing structural AI-driven storage demand. Nearline capacity is almost fully allocated through calendar 2027. Since the April earnings report, STX has climbed 41.2%, though it has slipped 9.21% over the past month as investors digest valuation.

Consensus sits just above management’s guided midpoint, a modest cushion given Seagate’s four consecutive beats ranging from 6.01% to 16.94%. Operating margin is guided to the lower 40% range, extending the leverage story.
HAMR Qualification and Margin Durability Take Center Stage
Tonight, I’ll be watching four things when Seagate reports.
- Mozaic qualification progress. Two of the four largest cloud customers were qualified in Q3, with the remaining two expected to complete qualification in the current quarter. Confirmation matters for the fiscal 2027 target of 70% of nearline exabytes on HAMR.
- Exabyte shipments. Polymarket traders assign a 95% probability that Q4 hard drive exabytes exceed 190, but only 51.5% above 210. Confidence in the 210 threshold dropped 24 percentage points in four days.
- Margin trajectory. Incremental gross margin has held above 70%, well ahead of the prior 50% framework. Investors will focus on whether pricing gains and HAMR mix keep that pace.
- Capital returns. Seagate retired $641 million in debt last quarter with roughly $400 million in convertible notes remaining. Management flagged that the majority will probably go to share buybacks once debt reduction winds down.
