Key Takeaways
- Seagate shares tumbled 7.5% following CEO Dave Mosley’s comments dismissing factory construction as too time-consuming.
- Company strategy prioritizes technological advancement through higher-density platters over expanding manufacturing capacity.
- Lead times for recording head wafers currently exceed nine months, with finished drives requiring an additional three months.
- Seagate now operates on a build-to-order framework with forward visibility extending four to five quarters.
- The firm’s Mozaic 3 HAMR platform has secured qualification across all targeted cloud service providers, with 50% exabyte transition projected for late 2026.
Seagate Technology (STX) experienced a sharp 7.5% decline on Monday, with shares retreating from approximately $795 to around $736, following remarks by CEO Dave Mosley at the JPMorgan Global Technology, Media and Communications Conference where he ruled out constructing additional manufacturing facilities.

During a discussion about scaling production capacity to address growing hard disk drive demand, Mosley delivered a clear message: constructing new facilities would require excessive time and risk creating surplus capacity.
“If we took the teams off and started building new factories or bringing up new machines that would just take too long,” Mosley explained. “You end up more capacity, if you will, but then you’d slow the rate of growth on that technology.”
Rather than pursuing physical expansion, Seagate is concentrating on maximizing storage density within existing infrastructure — prioritizing technological innovation over volume scaling.
The organization aims to achieve compound annual growth in the mid-20s percentage range through progressive platter density improvements, advancing from 3 terabytes per platter to 4, then ultimately 5 terabytes per platter. According to Mosley, this trajectory enables growth without the capital burden of constructing new manufacturing sites.
Tight Supply Chain Conditions
Seagate faces constrained supply conditions. Recording head wafers — an essential component — currently have procurement lead times stretching beyond nine months. Manufacturing completed drives adds another quarter to the timeline.
To navigate these constraints, Seagate has transitioned to a build-to-order operational model, providing the company with demand visibility spanning four to five quarters into the future.
Mosley conceded that customer demand is outstripping available supply, with clients requesting additional exabytes. However, he indicated that increasing unit production capacity only becomes viable if broader applications such as Edge AI gain traction, which would necessitate expansion beyond current data center concentrations.
Seagate’s Mozaic 3 HAMR (Heat-Assisted Magnetic Recording) platform has achieved qualification status with all intended cloud service providers. The organization anticipates reaching 50% exabyte crossover to HAMR technology during the latter half of calendar year 2026.
Valuation Metrics and Insider Transaction Patterns
STX currently trades at a P/E ratio of 69.77x — elevated relative to its earnings characteristics. GuruFocus designates the stock as considerably overvalued according to its GF Value assessment framework.
The GF Score for STX registers at 71 out of 100, with profitability and growth metrics each earning 7/10 ratings. Financial strength receives a comparatively lower score of 6/10.
Insider transaction patterns have attracted scrutiny. Company insiders divested $66.4 million in stock during the previous three-month period, with zero insider purchases recorded during that timeframe.
Seagate commands a market capitalization of roughly $164.89 billion and functions within a practical duopoly alongside Western Digital in the HDD marketplace.
The stock’s decline occurred solely in response to Mosley’s conference presentation, with no new earnings release or guidance revision announced that day.
