Seagate Was Supposed to Lose to SSDs. Here’s What $1,000 Invested 10 Years Ago Became

From Flash Casualty to AI Storage Backbone

Ten years ago, Seagate Technology (NASDAQ:STX | STX Price Prediction) looked like it was on the wrong side of history. Flash and SSDs were taking share in consumer and enterprise storage, and hard drives seemed headed for a slow fade.

Seagate narrowed its focus to high-capacity nearline drives for hyperscale cloud customers. The breakthrough was its HAMR-based Mozaic platform, which raises capacity by packing more data onto each disk. That way, the company grows without simply building more drives. Data center now accounts for 81% of total revenue, and “the vast majority of our Nearline Exabyte supply is now allocated under long-term supply agreements through calendar 2028.”

AI turned that niche into a growth engine. In fiscal Q1 2027, revenue rose 61.0% YoY to $4.23B, non-GAAP EPS hit a record $7.68, and non-GAAP gross margin reached 57.8%.

Seagate Kept Paying Dividends While the Business Turned Around

Income investors collected a check every quarter along the way. The quarterly payout was $0.63 in December 2016 and was just raised to $0.76. Seagate also retired $1.26B of debt in Q1 and $750M more after the quarter closed. Management now calls buybacks its “primary vehicle” for capital returns.

Seagate beat the index at every horizon, but most of the gain came late. CEO Dave Mosley pointed to a “big downturn” in storage only a few years ago, and anyone who held through it endured that slump. Timing matters even now: shares fell 30.06% over the past month, from $848.99 to $593.76, after record earnings failed to impress.

What Could Drive Seagate Higher, and What Could Derail It

The case for Seagate rests on HAMR continuing to deliver and long-term contracts protecting pricing. The case weakens if hyperscaler spending stalls and the old boom-bust cycle returns. Seagate is one of the picks-and-shovels names benefiting from the AI data center buildout (we profiled seven of these non-chipmaker suppliers, from power to storage, in a free report you can grab here).

The bull case: Management guides Q2 revenue of $4.80B and EPS of $9.20, expects to be net cash positive exiting calendar 2026, and has Mozaic 5 drives of upwards of 50 terabytes in development.

The bear case: Revenue depends heavily on a few large hyperscale customers. Tariffs, Middle East conflict, and possible dilution from the Exchangeable Senior Notes due 2028 add risk. Income buyers should also know the forward yield is just 0.49%.

Contract visibility through calendar 2028 supports the long-term story, while a 30% drop in a month-on-record result shows how volatile the shares remain. Investors should watch Q2 delivery against guidance and hyperscaler spending trends.
