Seagate Technology PLCSeagate posted fiscal Q4 revenue up 48.5% to $3.63B, EPS of $5.71 beating consensus, and record $3.1B free cash flow.
Seagate Technology is already shipping its HAMR-based Mozaic drives to 75% of the world's leading cloud customers, while Western Digital's competing 44TB Hammer drive will not reach hyperscalers until the first half of calendar year 2027. Seagate posted fiscal Q4 revenue of $3.63 billion, up 48.5% year over year, with non-GAAP earnings per share of $5.71 beating the $5.0932 consensus, and its Mozaic 4 drives, capable of up to 44 terabytes per drive, were shipping for revenue to those cloud customers by March. Western Digital, now a pure-play hard disk drive company after the Sandisk separation, reported revenue of $3.75 billion, up 43.8% year over year, earnings per share of $3.56, and gross margin of 54.4%, with growth driven by its 40TB ePMR drives. Both companies guided fiscal Q1 2027 revenue to roughly $4.10 billion. Seagate expanded gross margin to 52.3% from 37.4% year over year and posted record free cash flow of $3.1 billion for the year, though its shares are up 325.27% over the past year, while Western Digital trades at a price-to-earnings ratio of 17 with a cleaner balance sheet. The next test for Seagate is whether it can push 70% of nearline exabytes onto HAMR by fiscal 2027 without yield issues, while Western Digital's 44TB Hammer qualification with hyperscalers in early 2027 is critical.
