AI snapshot
Six angles, distilled from the data.
STX remains in a powerful multi-month uptrend and sits well above its 200-day average of 650.7, with the 50-day average also rising above 854.7. The stock is trading near the top of its 52-week range after a sharp rerating, so the regime favors momentum continuation as long as that trend holds.
Street sentiment is constructive: consensus is Buy with a 4.56/5 score and a $1,125 target, above the recent close. The pattern is broadly positive, with multiple target hikes in late July and only one recent downgrade, suggesting analysts still see upside after the run.
The setup is strong heading into the next report after seven straight EPS beats, including a 12.1% beat last quarter. Fiscal 2027 EPS is modeled at 36.16 versus 13.92 trailing, so shareholders should watch whether storage demand and margin leverage keep beating the higher bar.
Recent insider activity leans clearly negative, led by CEO William Mosley’s cluster of 15 sales on 2026-10-01. With no reported insider buys in the period, the pattern looks like profit-taking rather than a confidence signal, even if some sales may be routine.
Profitability is strong, with a 45.6% gross margin, 43.1% operating margin, and 26.1% net margin. Growth is also sharp, with revenue up 48.5% year over year and earnings up 148.8%, while free cash flow reached $4.243 billion in fiscal 2026.
STX stands out as a high-beta storage name with 37.15% ROE and 29.35% ROA, supported by strong cash generation. The valuation is rich at 71.48x earnings, so the setup favors execution over multiple expansion from here.

Earnings call summaries
Pick a quarter — each call distilled into takeaways, results, and a bull vs bear read.
Seagate capped fiscal 2026 with a strong revenue, margin and cash-flow beat, and management said fiscal 2027 should bring further sequential growth as HAMR and pricing continue to scale.· July 28, 2026
- June quarter revenue was $3.6 billion, up 17% sequentially and 48% year over year; non-GAAP EPS was $5.71, up 39% quarter over quarter and 121% year over year.
- Non-GAAP gross margin reached 52.7%, up 570 bps sequentially, while non-GAAP operating margin rose to 44.6%.
- Free cash flow topped $1.1 billion with a 31% margin, and fiscal 2026 free cash flow totaled a record $3.1 billion.
- HAMR momentum continued: nearline exabytes on HAMR reached about 40% of the run rate, and Mozaic 4 is ramping with the two largest global CSPs.
- Management guided September quarter revenue to $4.1 billion plus or minus $100 million and non-GAAP EPS to $7.30 plus or minus $0.20, with operating margin around 50%.
June quarter revenue was $3.6 billion, up 17% sequentially and up 48% year over year. Non-GAAP EPS was $5.71, up 39% quarter over quarter and 121% year over year. Non-GAAP gross margin was 52.7%, up 570 basis points sequentially, and non-GAAP operating margin was 44.6%, up 710 basis points sequentially. Free cash flow was more than $1.1 billion, with a 31% margin, and fiscal 2026 free cash flow was $3.1 billion. For the September quarter, Seagate guided revenue to $4.1 billion plus or minus $100 million, non-GAAP EPS to $7.30 plus or minus $0.20, non-GAAP operating expenses to about $300 million, and non-GAAP operating margin to around 50%.
Dave Mosley framed the quarter as a strong finish to an outstanding fiscal 2026 and emphasized three pillars: durable demand, the HAMR-based Mozaic roadmap, and disciplined execution. He said demand for mass-capacity storage is strong and growing, that cloud remains the biggest driver, and that AI is reinforcing long-term storage needs through training, inference, agentic applications and physical AI. His tone was confident and constructive, with repeated comments that Seagate expects fiscal 2027 revenue growth to outpace fiscal 2026 and that momentum should continue through the year.
Gianluca Romano highlighted the financial upside in the quarter, including $3.6 billion of revenue, 52.7% gross margin, 44.6% operating margin and $5.71 of non-GAAP EPS. He pointed to $187 million of CapEx in the June quarter, said fiscal 2026 CapEx was 4.7% of revenue, and reiterated a fiscal 2027 CapEx target of 4% to 6% of revenue. On the balance sheet, he said cash and cash equivalents were $1.7 billion, liquidity was $3 billion, gross debt was $3.6 billion exiting fiscal 2026, down $1.4 billion year over year, and net leverage improved to 0.4x; he also noted plans to retire another $1.2 billion of debt in the September quarter.
Analysts focused on gross margin, pricing, HAMR adoption, exabyte growth sustainability and the mix between hyperscale, neocloud and enterprise demand. Management said the strong September pricing reflects a wider supply-demand gap and some favorable contract roll-offs, but stressed the pricing strategy itself has not changed; they also said the business remains predictable through FY27 because orders are secured ahead of production. On HAMR, management said they hit the 40% nearline exabyte milestone and are on track for the next milestones, while emphasizing that the mix shift and product transitions, not unit growth, are what drive the investment and complexity.
The bull case from this call is that Seagate is still seeing strong cloud-driven demand, with data center now about 90% of exabyte shipments and nearline demand continuing to grow. Management also sees more upside from HAMR/Mozaic ramps, improved pricing, and expanding use cases like tiered storage for inference, agentic AI and physical AI, all while generating record cash and paying down debt.
The main risks flagged were that product transitions create factory complexity, temporary inefficiencies and yield challenges, and management acknowledged they must pause factories during some transitions. Pricing strength may not be linear because it depends on quarterly contract timing, output availability and customer qualification cycles, and management said every quarter will differ. They also said the mid-20% exabyte growth target remains the long-term framework, implying there are still execution limits even with strong demand.

A “Sell” may be a pre-scheduled 10b5-1 plan sale rather than a discretionary decision — read insider selling with that in mind.
