Seagate’s Q1 Earnings Dilemma on Oct. 27: Blockbuster AI Data Demand Confronts Rising Oversupply Fears

Seagate stock cratered 31% in a month on fears that a Toshiba supply surge will crush pricing, but the upcoming earnings report could either validate those fears or expose them as overblown. Watch one metric above all others to know…

White circuit lines emanate from the brain, connecting to four smaller, glowing, rounded-rectangle icons around it: 'HBM' (depicting stacked memory chips) on the top left, 'DRAM' (a RAM stick) on the bottom left, 'eSSD' (a CPU-like chip) on the top right, and 'NAND' (a circuit board pattern) on the bottom right. Wavy, sparkling light trails in shades of blue and purple flow between these components, set against a blurred background of a dark data center filled with server racks glowing with blue light. The overall aesthetic is futuristic and highly technological.

Seagate Technology (NASDAQ:STX | STX Price Prediction) reports fiscal first-quarter results on Oct. 27 after the bell. The shares fell 31.7% over the past month on oversupply fears. This report has to show that AI storage demand and pricing power still hold.

Record Results Run Into a Sharp Monthlong Selloff

Last quarter was Seagate’s fifth straight beat on both EPS and revenue. Non-GAAP EPS of $5.71 exceeded the $5.09 consensus. Revenue rose 48.5% year over year to $3.629 billion. Non-GAAP gross margin reached 52.7%, and free cash flow came in above $1.1 billion.

Management guided to $4.10 billion in revenue, plus or minus $100 million, and non-GAAP EPS of $7.30, plus or minus $0.20. CEO Dave Mosley said fiscal 2027 revenue growth should outpace fiscal 2026’s 34%.

Sentiment turned soon after. Reports that Toshiba plans a major capacity ramp for AI data center HDDs raised concerns of a supply glut. The stock slid from $923.11 on Sept. 23 to $630.49. Barron’s reported that Morgan Stanley has since come out in support of the battered stock.

Analysts Expect Triple-Digit EPS Growth

Metric Consensus Year-Ago Actual Implied YoY Growth
Q1 FY27 EPS $7.4031 $2.61 183.6%
Q1 FY27 Revenue $4.14 billion $2.629 billion 57.5%
FY27 EPS $36.6633 $15.58 135.3%
FY27 Revenue $19.08 billion $12.195 billion 56.5%

Consensus EPS sits above the guidance midpoint. It has risen since $5.8791 90 days earlier.

Price per Exabyte Will Settle the Oversupply Debate

Pricing is the first metric to watch. June-quarter price per exabyte rose 10% year over year, and management said the supply-demand gap had widened from a few quarters earlier. Management also noted some available output in fiscal Q1, priced favorably. If Toshiba’s ramp is putting pressure on deals, it should show up here first.

Contract coverage is the second test. Mosley said the vast majority of nearline exabytes are allocated into calendar 2028, and customers want to extend planning through 2029 and beyond. You should listen for whether those horizons keep stretching.

Third is the Mozaic 4 ramp. The 44-terabyte HAMR platform is scaling up with the two largest global cloud service providers, and management expected an even stronger contribution in the September quarter. Seagate is one of the picks-and-shovels AI infrastructure names we broke down in a free report on seven stocks powering the AI boom beyond the chipmakers. Seagate plans to exit calendar 2026 with 50% of HAMR exabytes on Mozaic 4. Product transitions bring yield challenges, so delivery against the about 50% operating margin guide matters.

Finally, capital returns. Debt should fall to about $2.4 billion this quarter, and management expects buybacks to increase over the next several quarters.

Locked-In Contracts Have to Beat the Glut Narrative

STX price target

Seagate keeps exceeding estimates, but the stock still sold off hard on competition headlines. The options market leans cautious, with a full-chain put/call ratio of 1.06. This report gives management room to show that long-term contracted pricing drives results. If Mosley supports the 2028 allocation story with firm pricing and margin data, I think the oversupply concerns lose much of their hold.
