Seagate Technology Holdings Plc (STX Quick QuoteSTX - Free Report) has delivered a strong start to fiscal 2027, strengthening the investment case for companies benefiting from rising AI infrastructure spending and expanding cloud storage requirements. Fiscal first-quarter revenue rose from $2.63 billion in the year-ago quarter to $4.23 billion, reflecting stronger demand for mass-capacity storage products, improved pricing and rising data center requirements.

Non-GAAP gross margin was 57.8% compared with 40.1% a year earlier. This improvement indicates that Seagate is benefiting not only from higher shipments but also from better pricing and a more favorable product mix. Free cash flow reached approximately $1.48 billion, while operating cash flow was $1.69 billion. These results point to improved financial flexibility and greater potential to reward shareholders.

STX’s shares have gained 173.7% in the past year, outperforming the Zacks Computer-Integrated Systems industry’s growth of 117%. The stock has also outperformed the Zacks Computer & Technology sector and the S&P 500’s growth of 14.7% and 13.3%, respectively.

STX faces tough competition from HDD giant Western Digital Corporation (WDC Quick QuoteWDC - Free Report) and SSD manufacturers such as Samsung and Micron Technology (MU Quick QuoteMU - Free Report) , as well as players from the broader data-storage market like NetApp, Inc. (NTAP Quick QuoteNTAP - Free Report) . NetApp’s enterprise storage and cloud data-management solutions serve overlapping customer needs, although its business model differs from Seagate's HDD-focused operations. WDC, MU and NTAP have gained 163.2%, 317.5% and 85.4%, respectively.

However, after a strong earnings performance, investors must consider whether STX still offers attractive upside or whether its valuation already reflects much of the positive outlook.

Let's examine the earnings performance, growth drivers, risks and investment strategy for STX stock.

AI Infrastructure is a Major Growth Catalyst for STX

The company's recent results highlighted improving profitability, strong cash generation and sustained demand for mass-capacity storage. Its position in the HDD market, particularly through HAMR technology, allows it to capitalize on the growing volume of data generated by AI workloads. Demand remains strong across data centers and edge markets, driven by AI adoption and growing digital data volumes. Seagate expects revenue growth and margin expansion throughout fiscal 2027, with long-term demand visibility extending beyond 2030.

Industry supply remains tight, with much of Seagate's exabyte capacity allocated through 2028. Multiyear supply agreements extending through 2030 improve revenue visibility, support pricing stability and enable the company to align production with customer demand. It continues to advance its HAMR technology through its Mozaic platform. It is ramping Mozaic 4 drives with capacities of up to 44TB and developing Mozaic 5 drives targeting 50TB, with qualification expected by the end of 2027. STX also expects 40TB drives to ramp over the coming quarters, while progressing toward its 4TB-per-platter target and increasing HAMR's share of shipments to 50% by year-end.

The company is strengthening collaboration with hyperscalers and enterprise customers through long-term supply agreements, product qualification and coordinated capacity planning. Emerging workloads, including AI acceleration, key-value (KV) cache storage and physical AI, could create additional demand opportunities over time. With no significant debt maturities until 2029, Seagate has greater flexibility to prioritize shareholder returns while investing in technology development and aligning production with sustained storage demand.

Debt Reduction Strengthens STX's Financial Position

Seagate also made substantial progress in improving its balance sheet. During the fiscal first quarter, the company retired approximately $1.2 billion in principal debt, reducing gross debt to $2.4 billion. After the quarter ended, it retired another $750 million in principal debt, bringing gross debt to $1.6 billion. At the end of the reported quarter, it held $1.3 billion in cash and cash equivalents. This deleveraging is likely to reduce interest expenses, improve financial resilience and provide greater flexibility during periods of macroeconomic swings.

Lower debt may also enable the company to direct more future cash flow toward shareholder returns and strategic investments. Seagate returned $568 million to shareholders through dividends and share repurchases during the quarter. The board also declared a quarterly cash dividend of 76 cents per share, payable on Jan. 7, 2027, to shareholders of record as of Dec. 23, 2026. However, investors should continue to assess capital allocation decisions alongside investment requirements and future operating conditions.

STX’s Fiscal Q2 Guidance Signals Further Growth

Strong pricing, favorable product mix and operational efficiencies are supporting margin expansion. Although rising external component costs create pressure, price increases are more than offsetting these costs, with quarterly average selling price growth trending in the mid-teens. Seagate expects operating margins to remain in the 50-55% range for fiscal second quarter, while maintaining capital expenditure at 4-6% of revenue and focusing on disciplined capacity expansion rather than acquisitions.

Management expects strong operating performance to continue. STX expects continued sequential growth, driven by strong demand, higher exabyte shipments and value-based pricing. It forecasts revenue of $4.8 billion (+/- $100 million), up 7% year over year at the midpoint, and non-GAAP EPS of $9.20 (+/- 20 cents). Operating expenses are expected to remain near $300 million. Other expenses are projected to decline to about $25 million from $38 million this quarter, reflecting lower interest costs after October's debt reduction.

Despite its strong performance, Seagate faces several risks such as fluctuations in data center spending and changes in cloud providers’ investment plans, which could weaken demand for high-capacity drives. Delays in HAMR adoption or manufacturing challenges could also limit the benefits of higher recording density. Additionally, competition from SSDs and other storage technologies may pressure demand and pricing in certain applications.

Estimate Revision Trend for STX

STX is currently witnessing an uptrend in estimate revisions. Earnings estimates for fiscal 2027 have been revised up 1.8% to $36.72 over the past 60 days, while estimates for fiscal 2028 have risen 2.08% to $59.49.

Going by the price/earnings ratio, the company’s shares currently trade at 16.22 forward earnings compared with 10.47 for the industry.

In comparison, the forward 12-month price/earnings multiple for MU, NTAP and WDC are 5.13X, 25.09X and 16.1X, respectively.

Investment Verdict: Is STX Stock Still a Buy?

STX reported record September-quarter results and forecast further sequential growth in December, driven by the Mozaic 4 ramp, value-based pricing and operating leverage. Following significant debt reduction and a return to investment-grade status, Seagate raised its dividend to 76 cents per share and signaled higher buybacks starting in calendar 2027. External component cost inflation and product-transition scrap remain key execution risks.

Overall, Seagate appears well-positioned to benefit from the growing need to store and reuse data. Investors should monitor upcoming earnings, HAMR deployment, free cash flow and demand trends to assess whether the company's improving fundamentals can support further long-term shareholder value. Currently holding a Zacks Rank #2 (Buy), STX deserves portfolio consideration as a long-term AI infrastructure investment.
