Seagate stock faces execution test as HAMR ramp accelerates

Seagate Technology Holdings plc is entering a more demanding execution phase after setting out a stronger fiscal second-quarter outlook. In an analysis published on November 2, Zacks said higher cloud storage demand, pricing and the transition to heat-assisted magnetic recording, or HAMR, underpin the next growth step.

Seagate stock traded at 449.50 euros on Lang & Schwarz at 11:37 CET on Tuesday, November 10, 2026. The quote provides a current trading reference, while the near-term investment case rests on whether Seagate can convert demand visibility into shipments and sustain its pricing advantage.

Higher guidance raises the execution bar

Management expects fiscal second-quarter revenue of 4.8 billion US dollars, plus or minus 100 million US dollars, and non-GAAP earnings of 9.20 US dollars per share, plus or minus 20 cents. The midpoint of the revenue outlook implies roughly 70 percent year-over-year growth, according to Zacks.

The company also expects non-GAAP operating margin to move toward the mid-50 percent range, with operating expenses near 300 million US dollars. A significant increase in exabyte shipments and continued benefits from value-based pricing are expected to support the quarter.

HAMR ramp remains the key test

Seagate expects HAMR to represent roughly half of its nearline exabyte shipment run rate by the end of calendar 2026. The Mozaic 4 platform supports capacities of up to 44 terabytes and is ramping with two leading cloud service providers. The technology is intended to raise capacity per drive and support exabyte growth without relying primarily on higher unit production.

Nearline shipments rose 1 percent sequentially to 198 exabytes in the September quarter as Seagate staged Mozaic 4 products ahead of customer qualifications. The December quarter therefore depends on qualification timing, manufacturing execution and the ability to increase shipments without losing margin support. Longer HAMR production cycles and higher external component costs remain relevant risks.

Contracts improve visibility, not certainty

Zacks reports that most of Seagate’s nearline exabyte supply is allocated under long-term agreements through calendar 2028, while some cloud customer agreements extend through 2030. Build-to-order contracts establish configurations and pricing through calendar 2027, with 2028 terms expected to be finalized over the coming quarters.

Those commitments improve planning visibility, but they do not remove execution risk. Customer qualifications, product mix, manufacturing yields and pricing will determine how much of the contracted demand becomes reported revenue and cash generation.

The broader US equity backdrop remains relevant for storage shares, as shown by the S&P 500.
