On September 21, Seagate Technology PLC rose 4.35% in regular trading, trading at $909.26/share, with turnover of $198 million.

On the news front, Seagate's nearline HDD capacity has been fully booked through year-end, with select major clients securing supply allocations through 2029, while retail mechanical hard drive prices have reached all-time highs. The supply-demand imbalance stems from surging AI data center storage requirements. Seagate, Western Digital, and Toshiba collectively control approximately 80% of global HDD production capacity, with priority fulfillment of data center orders tightening retail supply channels. The company's most recent quarterly revenue reached $3.63 billion, a 48.5% year-over-year increase, while gross margin expanded significantly from 37% to 52%.

Further underpinning the outlook, the company's CFO recently disclosed that 80-90% of data center storage shipments will leverage its HAMR (Heat-Assisted Magnetic Recording) technology. A separate industry survey noted that 99% of enterprises expect AI to drive storage demand higher, though only 38% report adequate infrastructure readiness. Within the sector, Western Digital gained 4.0%, Dell Technologies rose 2.91%, and Super Micro Computer added 3.12%.
