In brief

FY2026 revenue grew 34%, margins rose sharply and free cash reached a record. But storage is cyclical, the balance sheet carries debt, and the mechanical 53/100* score has a period-mapping issue. Official results therefore matter more than the score.

What does Seagate do?

Seagate produces high-capacity hard drives for cloud data centres and enterprises. HAMR technology aims to store more data per drive. As AI generates more data, demand for economical storage may rise, but customer orders and pricing remain cyclical.

What do FY2026 results show?

Revenue rose 34% to $12.20 billion, GAAP gross margin reached 45.6% and operating margin 33.6%. Net income was $3.18 billion, operating cash $3.7 billion and free cash $3.1 billion.

The company shipped 789 exabytes of HDD capacity, retired $1.4 billion of debt and returned $810 million through dividends and repurchases. The recovery therefore appears in cash as well as accounting profit.

How should the five categories be read?

Growth 5/100 model result: The five-year cycle looks weak, but FY2026 revenue growth was 34%. The category is cautious because of earlier contraction and does not capture the latest recovery on its own.

Profitability 80/100: Official FY2026 gross margin of 45.6% and operating margin of 33.6% are strong. The model gave missing gross margin a neutral score and capped return on capital at its maximum.

Cash flow 33/100 model result: The model uses the prior year's $818 million. Official FY2026 free cash of $3.1 billion is much stronger, though the disk cycle can change cash generation quickly.

Balance sheet 50/100: The model shows a 1.38 current ratio and five-times net debt/free cash using the prior cash input. Retiring $1.4 billion of debt in FY2026 is positive, but leverage risk has not disappeared.

Shareholder policy 85/100: Stock compensation is low, the approximate valuation measure does not signal an extreme premium, and FY2026 distributions were about 26% of official free cash. The model's 73% ratio uses prior-year cash.

Critical combinations

Positive combination
  • AI data growth + mass-capacity drives
  • HAMR transition + rising margin
  • Record cash + debt reduction
Risk combination
  • Cyclical orders + fixed costs
  • Debt + cash volatility
  • Customer concentration + technology execution risk

What matters next?

The company expects cloud data-centre demand and its Mozaic HAMR platform to support momentum into 2027. The long-term test is combining capacity growth with pricing discipline and preserving margins through weaker parts of the cycle.

What does this mean?

Seagate delivered a strong operational and cash recovery in FY2026. One strong year does not remove the storage cycle; debt, margins and free cash should be monitored together. This is not investment advice.

Sources and method

Where the figures come from

  • Seagate FY2026 Form 10-K, SEC — 53-week fiscal year ended 3 July 2026; primary source.
  • Seagate FY2026 results — the company's official annual and Q4 results release.
  • The automated system labels the filing FY2027 and uses FY2025 comparatives such as $9.10 billion revenue and $818 million free cash. Official FY2026 figures are $12.20 billion revenue and $3.10 billion free cash. The 53 score is only the capped mechanical result; mis-period inputs are not used in the interpretation.
