Seagate Technology reported a sharp increase in revenue and record profitability for its fiscal first quarter of 2027, but its shares fell in after-hours trading following the results. The data-storage manufacturer posted $4.233 billion in revenue, up 61% from a year earlier, and forecast another strong quarter as demand for high-capacity storage continues to benefit from expanding data-centre infrastructure.
The company announced its results on October 27, 2026, for the quarter ended October 2. Its non-GAAP diluted earnings per share reached $7.68, while free cash flow climbed to $1.5 billion. Both revenue and adjusted earnings exceeded analyst expectations.
Revenue and adjusted earnings exceed expectations
Seagate's quarterly revenue increased from $2.629 billion in the same period a year earlier to $4.233 billion. The improvement reflected stronger demand for the company's mass-capacity storage products, which are used by cloud providers, enterprises and other organisations managing growing volumes of digital information.
Non-GAAP diluted earnings per share rose to $7.68 from $2.61 a year earlier, an increase of approximately 194%. On a GAAP basis, diluted earnings per share were $7.59, compared with $2.43 in the prior-year quarter.
The distinction matters because adjusted earnings exclude certain items under the company's non-GAAP methodology. Investors should therefore consider both measures when assessing the scale and sustainability of the improvement.
Seagate's non-GAAP gross margin reached 57.8%, compared with 40.1% a year earlier. Its non-GAAP operating margin expanded to 50.7%, up from 29% in the prior-year period. These figures show that profitability improved substantially alongside revenue growth.
AI infrastructure is supporting storage demand
The growth in Seagate's results comes as technology companies expand data centres to support artificial intelligence services, cloud computing and other data-intensive workloads.
AI systems generate and process large quantities of information, while businesses increasingly retain data for future use, compliance, analytics and model development. High-capacity hard disk drives remain important in many storage environments where capacity and cost per unit of storage are key considerations.
Seagate specialises in mass-capacity storage and has been developing heat-assisted magnetic recording, or HAMR, technology to increase the amount of information that can be stored on a disk. Chief Executive Dave Mosley said the company was seeing continued growth in data creation, retention and reuse, while long-term customer demand visibility supported its expectation of a multiyear growth phase.
That outlook is management's assessment rather than a guarantee of future results. Actual demand will depend on customer investment plans, storage requirements, competing technologies and broader economic conditions.
Record free cash flow strengthens the balance sheet
Seagate generated $1.7 billion in operating cash flow and $1.5 billion in free cash flow during the quarter. The company described the free-cash-flow result as its highest ever.
Strong cash generation gave Seagate room to reduce debt and return capital to shareholders. During the quarter, it retired approximately $1.2 billion in principal debt and returned $568 million through dividends and share repurchases.
Gross debt fell to $2.4 billion at the end of the quarter. Seagate subsequently retired another $750 million of principal debt, bringing gross debt to $1.6 billion, according to the company's release.
The board also increased the quarterly cash dividend by approximately 3% to $0.76 per share. The dividend was scheduled to be paid on January 7, 2027, to shareholders of record on December 23, 2026.
These developments show that the quarter's performance extended beyond reported earnings: Seagate also generated substantial cash and reduced its debt burden. However, future distributions remain subject to board decisions and the company's financial requirements.
December-quarter guidance exceeds analyst expectations
Seagate forecast fiscal second-quarter 2027 revenue of $4.8 billion, plus or minus $100 million. That implies a range of $4.7 billion to $4.9 billion.
The company projected non-GAAP diluted earnings per share of $9.20, plus or minus $0.20, giving a range of $9.00 to $9.40.
The midpoint of the revenue outlook was above the approximately $4.55 billion consensus cited in market reporting. The midpoint of the adjusted earnings range also exceeded published analyst estimates.
The guidance indicates that management expects the strong operating performance to continue into the December quarter. Nevertheless, the company cautioned that actual results could differ materially from its outlook because of changing market conditions and other business risks. Its adjusted earnings guidance also excludes certain anticipated share-based compensation expenses and other items that cannot be reliably predicted.
Why did Seagate shares fall after the earnings release?
Despite the strong results and upbeat outlook, Seagate shares declined in extended trading after the October 27 announcement. The stock had closed the regular session higher before reversing direction after the earnings release.
Market reports placed the after-hours decline at roughly 6% to 8%, depending on the time and trading source. Extended-hours prices can fluctuate, so the percentage should be understood as a snapshot rather than a final closing result.
The decline illustrates an important feature of earnings-season trading: a company can beat estimates and still see its shares fall. Share prices reflect expectations about future performance as well as reported results. If investors had already priced in strong growth, even an impressive earnings report might not be enough to attract additional buying.
Profit-taking after a substantial share-price advance is one possible explanation. Investors may also have reassessed the valuation implied by the company's expected growth, its exposure to a concentrated group of large customers, or the possibility that technology companies could adjust their infrastructure spending.
However, the after-hours move alone does not establish which factor was responsible. Without a clear explanation supported by management commentary or reliable market reporting, it would be premature to attribute the decline to one specific concern.
What the results mean for the data-storage industry
Seagate's results provide evidence of strong current demand for mass-capacity storage and demonstrate how that demand can translate into higher revenue, margins and cash generation.
For cloud infrastructure providers, storage is an essential component of data-centre investment alongside processors, networking equipment, memory and power infrastructure. Demand for these components can grow at different rates, and storage suppliers remain exposed to production capacity, technology transitions, pricing and customer purchasing cycles.
The quarter also highlights why investors distinguish between operating performance and stock-market valuation. Seagate delivered a strong financial result, but its share-price reaction showed that expectations and positioning can influence trading even when reported figures exceed forecasts.
What to watch next
Investors will monitor Seagate's December-quarter results against its revenue guidance of $4.7 billion to $4.9 billion and adjusted EPS outlook of $9.00 to $9.40. Progress in HAMR technology, customer demand visibility, gross margins and free cash flow will also be important indicators.
For now, the company has reported a record quarter and issued a strong outlook. Whether that performance supports further share-price gains will depend on execution, future demand and the valuation investors are willing to assign to its expected earnings.
