Seagate (STX) Falls 7% After Hours Despite Q1 Beat

Seagate (STX) shares fell about 7% after hours despite a Q1 beat and guidance above forecasts, underscoring sky-high expectations for AI storage stocks.

Lead

The shares closed near $668 before the report. They had risen more than 4% during the regular session and are up more than 50% for the year. In extended trading they fell between roughly 6% and 9%, touching about $610 at the low end.

What Did Seagate Report for Its Fiscal First Quarter?

Seagate reported revenue of $4.23 billion for the quarter ended October 2, up about 61% from $2.6 billion a year earlier and ahead of the $4.11 billion consensus. Non-GAAP diluted EPS was $7.68 against an expected $7.39, up from $2.61 a year ago.

Profitability rose faster than sales. Non-GAAP gross margin reached a record 57.8%, up from 40.1% a year earlier and 510 basis points higher than the prior quarter. Non-GAAP operating income was $2.15 billion, an operating margin of about 50.7%. Non-GAAP net income was $1.78 billion, compared with $583 million a year earlier.

Operating cash flow was $1.7 billion and free cash flow was $1.5 billion, the highest in the company's history. Chair and CEO Dave Mosley called it another quarter of record profitability.

What Did Seagate Guide for the December Quarter?

Seagate guided fiscal Q2 revenue to $4.8 billion, plus or minus $100 million, and non-GAAP EPS to $9.20, plus or minus $0.20. Consensus had stood near $4.53 billion to $4.56 billion in revenue and about $8.58 to $8.61 in EPS. The midpoints are roughly 5% to 6% above revenue forecasts and about 7% above EPS forecasts.

Management tied the outlook to demand from cloud and data-center customers. These customers are storing more training data, model outputs and archives as artificial intelligence workloads expand. The company said its HAMR-based Mozaic product line raises areal density, meaning more terabytes per platter, while it keeps supply discipline. That discipline holds back capacity growth, supports pricing and sustains the margins.

Why Did Seagate Shares Fall Despite the Beat?

Seagate shares fell because the results, strong as they were, did not clear the higher bar investors had set after a steep run in storage names. When a stock has more than doubled in a year, the market judges a quarter against buy-side expectations, not published consensus. Some of those expectations sat above the guidance range.

Margin expansion is also a concern. A 1,770 basis point year-on-year gain in gross margin is hard to repeat. Investors are weighing how long pricing power and tight supply can hold before customers push back or competitors add capacity. Valuation has also rewarded the sector heavily, so the shares are sensitive to any sign that growth is peaking.

The reaction does not point to a weaker business. It points to a stock already priced for exceptional execution, where a clean beat and a raise count as in-line.

How Is Seagate Returning Capital and Managing Its Balance Sheet?

Seagate paid $168 million in dividends and repurchased $400 million of stock during the quarter. It retired $1.2 billion of debt and repaid another $750 million after quarter-end, bringing gross debt to $1.6 billion. Cash and equivalents stood at $1.26 billion.

The board raised the quarterly dividend 3% to $0.76 per share, payable January 7, 2027. Diluted shares outstanding were about 232 million.

Strategic Context

Hard drives remain the main low-cost medium for bulk data storage, the layer beneath the flash and memory chips used to run AI models. Hyperscalers are accumulating data faster than they can discard it, which has lengthened demand cycles and tightened the market for high-capacity drives. For Seagate, the strategic task is converting the demand into higher-density products without adding capacity that would erode pricing.

Outlook

Seagate enters fiscal Q2 with record margins, strong cash generation, a shrinking debt load and guidance above consensus. The after-hours decline reflects positioning and valuation, not a deterioration in fundamentals. The next test is whether the company delivers the $4.8 billion revenue target and holds margins near current levels. The result will shape sentiment toward AI storage and memory names across the sector.
