Seagate (STX) stock jumped nearly 7% early-market trading after it crushed earnings expectations and showcased that its transformation into a high-margin AI storage business is accelerating.

What the Market Is Telling Us About STX Stock

The surge in STX stock reflects investor excitement that Seagate’s shift toward high-capacity AI-driven storage is delivering massive profitability improvements.

The company is no longer a commoditized hard drive maker struggling with thin margins. It’s becoming a high-margin supplier of specialized storage for data centers powering AI applications.

Seagate shipped 182 exabytes in the September quarter, up 32% year-over-year. Data center revenue accounted for 80% of total revenue, totaling $2.1 billion, up 13% sequentially and 34% year-over-year.

Cloud exabyte demand increased for the ninth consecutive quarter, with nearly 80% of nearline volume coming from drives at or above 24 terabytes.

The real story is HAMR technology—Heat-Assisted Magnetic Recording. This next-generation hard drive technology allows Seagate to pack significantly more data onto each disk.

The company now has five global cloud service providers qualified on its Mozaic 3+ terabyte-per-disk products, which deliver capacities up to 36 terabytes per drive.

Seagate shipped over 1 million Mozaic drives in the September quarter and expects to reach the 50% exabyte crossover for HAMR drives in the second half of calendar 2026.

For STX stock, the margin expansion is the key metric investors are watching. Incremental margins came in at nearly 70% in the September quarter, well above the 50% target management outlined at its May Analyst Day.

CFO Gianluca Romano said the company is executing better than expected due to faster adoption of higher-capacity HAMR drives and an effective pricing strategy.

STX Stock Valuation Model (TIKR)

Seagate’s pricing approach has been consistent for about 10 consecutive quarters. When the company renegotiates contracts, it slightly increases pricing for the same product.

As customers move to higher-capacity products, they get a lower price per terabyte, but Seagate benefits from a lower cost per terabyte due to product mix.

Revenue per terabyte has remained stable despite the significant shift toward higher-capacity drives, which shows pricing discipline.

Supply remains tight, and CEO Dave Mosley said nearline production is largely committed under build-to-order contracts through calendar 2026, with longer-term agreements providing visibility through calendar 2027.

Seagate isn’t planning to add unit capacity. Instead, it’s adding exabyte capacity by transitioning customers to higher-capacity drives through product upgrades.

AI demand is driving the urgency, as Mosley highlighted that AI inferencing is creating explosive growth in unstructured data, particularly video content.

One major hyperscaler reported a 50-fold increase in monthly token consumption over the past year. Video is a huge driver—over 80% of internet traffic is now video content. AI-generated videos make this even more pronounced.

Google reported that over 275 million videos were generated on its Veo platform within the first five months. A one-minute AI video can be up to 20,000 times larger than a 1,000-word text file.

This creates massive demand for cost-effective, high-capacity storage. Hard drives remain the most economical solution for storing enormous volumes of data that need to be retained long-term but accessed less frequently.

Seagate’s HAMR technology provides a sustainable cost advantage compared to alternative storage technologies.

The company is also beginning qualification of its Mozaic 4+ terabyte-per-disk platform with a second major cloud customer.

This platform will offer capacities up to 44 terabytes, with an initial volume ramp starting in the first half of calendar 2026. Seagate expects to remain on its long-term roadmap toward 10 terabytes per disk.

Seagate generated $427 million in free cash flow despite a substantial variable compensation payout.

Cash and cash equivalents increased 25% sequentially to $2.4 billion, including an undrawn credit facility. Net leverage dropped to 1.5 times adjusted EBITDA, and S&P upgraded Seagate’s credit rating earlier this month, recognizing the improved financial profile.

Seagate maintained its three-year revenue CAGR target of around 20% as it expects to grow revenue while expanding margins as customers shift to next-generation storage solutions.

Management emphasized that the best years are still ahead as AI adoption drives structural demand for exabyte-scale storage.
