Seagate stock has staged a notable recovery after a volatile reaction to its latest earnings, with investors refocusing on one central figure: management’s forecast for roughly 56% year-over-year revenue growth in the September quarter. That guidance arrived alongside record profitability and a 13th consecutive quarter of gross margin expansion.
Shares of Seagate, ticker STX, recently traded around $811.74 after previously falling 8.53% on the earnings-day session to $747.30 and then recovering in after-hours trading. The rebound suggests the market is reassessing whether the selloff fully reflected the company’s improving operating leverage and stronger data-center demand.
The broader backdrop has also helped. A July 2026 inflation reading showing headline CPI at 3.4% and core CPI at 2.5% matched expectations and supported risk appetite across technology, including storage and memory names.
Key Facts
- Seagate reported fiscal fourth-quarter revenue of $3.629 billion, up 48% year over year and above its $3.45 billion guidance midpoint.
- Non-GAAP gross margin reached a record 52.7%, up 570 basis points sequentially and marking 13 straight quarters of expansion.
- Management guided the September quarter to about $4.1 billion in revenue and non-GAAP EPS of $7.30, implying roughly 56% year-over-year revenue growth at the midpoint.
- Data center revenue rose to $2.9 billion, up 57% year over year, with 195 exabytes shipped into that segment.
- Gross debt fell to $3.6 billion from $5.0 billion a year earlier, with another $1.2 billion of retirement planned for the September quarter.
Seagate Stock and HAMR Storage Growth
The latest quarter highlighted why Seagate has become one of the more closely watched names in the storage hardware space. Revenue growth was strong, but the more important development was margin expansion. Non-GAAP operating margin climbed to 44.6% from 26.2% a year earlier, while non-GAAP EPS jumped to $5.71 from $2.59. Those numbers point to a business benefiting from scale, pricing power and a richer product mix.
At the center of the story is the company’s transition to HAMR, or heat-assisted magnetic recording, which allows higher-capacity drives and better economics. Seagate said HAMR-based drives represented about 40% of the nearline exabyte shipment run rate by the end of fiscal 2026, and it is targeting 70% penetration by June 2027. That target matters because investors are increasingly treating Seagate less like a mature hard-drive maker and more like a supplier with a technology-led upgrade cycle tied to hyperscale data centers.
The company’s customer exposure also explains why the market is paying attention. Data center revenue accounted for the large majority of exabyte shipments, underscoring how dependent Seagate has become on cloud and AI-related storage demand. If hyperscalers continue buying high-capacity drives to support data retention, retrieval and infrastructure expansion, Seagate may continue to deliver stronger pricing and margin performance than many investors once expected from the hard-disk-drive industry.
Seagate’s earnings profile is being reshaped by one powerful combination: higher-capacity drives, tighter supply and a margin streak that has now lasted 13 straight quarters.
Why the September Quarter Matters Most
For investors, the September-quarter outlook is the key data point. Management’s forecast of $4.1 billion in revenue, plus or minus $100 million, implies about 13% sequential growth from the June quarter. The EPS midpoint of $7.30 suggests even faster profit expansion, showing that incremental revenue is falling through at a high rate.
That guidance also indicates the favorable pricing environment is still intact. Seagate signaled higher exposure to non-contract exabyte sales, which can lift margins when supply is tight and customers are willing to pay more for incremental capacity. The trade-off is that spot exposure creates more earnings sensitivity if market conditions weaken later.
Implications for Investors
For equity investors, Seagate presents a mix of momentum, execution strength and valuation risk. On one hand, the company is producing record free cash flow, deleveraging its balance sheet and benefiting from a visible technology transition. Full-year free cash flow reached a record $3.1 billion, and debt reduction improves flexibility for future capital returns or strategic investment.
On the other hand, the stock still carries high expectations even after retreating from prior highs. Seagate’s 52-week range spans $151.23 to $1,145.00, a reminder that sentiment in AI-adjacent infrastructure names can shift quickly. While annualizing the September-quarter EPS midpoint points to a much lower forward earnings multiple than trailing figures suggest, the market is still assigning Seagate a premium based on the assumption that HAMR adoption, pricing discipline and hyperscale demand remain durable.
The main watch-points are clear. First, investors should track whether HAMR penetration continues toward the 70% target by June 2027. Second, exabyte shipment growth will matter more than headline revenue because it offers a cleaner read on underlying storage demand. Third, any sign of supply loosening across the storage market could pressure spot pricing and narrow margins. A company leaning into non-contract sales benefits disproportionately in a tight market, but that same strategy can reverse if capacity catches up.
Balance sheet strength is an important offset. A reduction in gross debt from $5.0 billion to $3.6 billion over the past year, with another $1.2 billion expected to be retired, gives Seagate more resilience than many hardware peers in a downturn. For long-term investors, that deleveraging may be as important as near-term earnings beats.
Seagate now sits at a crucial point where strong fundamentals are colliding with a still-demanding valuation. If management continues to hit growth and margin targets, the recent rebound could extend; if execution slips, the stock’s volatility suggests the market will react quickly.
