Seagate Technology (STX) is rallying after reporting fiscal third-quarter 2026 results that topped expectations and pairing the beat with optimistic guidance for fiscal Q4 2026. Management pointed to record profitability and close to $1 billion in free cash flow as evidence that demand conditions—especially for nearline, mass-capacity storage used in data centers—remain strong and are improving operating leverage.

In its fiscal Q3 2026 release, Seagate said it exceeded the high end of its revenue and EPS guidance and delivered record margin performance while producing close to $1 billion in free cash flow. For fiscal Q4 2026, the company guided to revenue of about $3.45 billion, plus or minus $100 million, implying sequential growth from Q3 levels and reinforcing the narrative that the current upcycle has momentum into the next quarter.

The market is treating the results as confirmation that hyperscale and enterprise customers are prioritizing storage capacity additions tied to AI workloads, which tend to expand data retention and training/inference datasets. Seagate’s commentary on technology progress—alongside improving mix toward higher-capacity drives—adds to expectations for sustained pricing discipline and better margins through the cycle.
