Seagate Technology Holdings plc (STX)

Seagate Technology Holdings plc is a provider of mass-capacity data storage, with nearly 50 years of history. It designs and manufactures hard disk drives (HDDs), storage systems and related solutions that help hyperscale companies, cloud service providers, enterprises and consumers protect, create and manage data. The company is vertically integrated and focuses its technology roadmap on increasing areal density, including its Mozaic platform, which uses its implementation of heat-assisted magnetic recording (HAMR). It also develops performance technologies such as multi-actuation, advanced channel coding and signal processing.

Seagate serves two principal end markets. The Data Center portfolio includes HDDs of up to 44TB and storage systems of up to 3.5PB, built for AI-enabled cloud computing, business-critical applications, content delivery, backup and archive. The Edge / Internet of Things (Edge IoT) portfolio includes storage products from 1TB to 32TB for video and image applications, network-attached storage, smart infrastructure, personal computing, gaming, streaming, creative workflows and backup. The company reports a single reportable business segment, and the vast majority of its business comes from Data Center markets.

Data Center products are sold primarily to cloud service providers, original equipment manufacturers (OEMs), distributors and enterprise organizations. Many major customers buy under master purchase agreements, with deliveries based on purchase orders and demand forecasts. For certain products, particularly high-capacity nearline drives, Seagate works with key customers on longer-term forecasts and supply commitments. Edge IoT products are sold through OEMs, distributors, retailers and third-party resellers, with a retail channel serving casual users, gamers and creative professionals. Distributors operate under non-exclusive agreements that typically include limited return rights and price protection. Edge IoT demand is seasonal, with higher sales typically in the first half of the fiscal year.

Seagate designs and makes many critical HDD components itself, including read/write heads and magnetic recording media, and uses strategic suppliers and contract manufacturers for selected components and assembly. Component manufacturing, subassembly, and final assembly and test take place in China, Malaysia, Northern Ireland, Singapore, Thailand and the United States. Some components and raw materials, including rare earth elements, precious metals and specialized alloys, come from a limited number of suppliers. Primary R&D facilities are in Northern Ireland, Singapore, Thailand and the United States. Competitors include HDD makers Western Digital and Toshiba Electronics Devices & Storage, NAND flash suppliers, and storage systems providers. As of July 3, 2026, Seagate held about 3,036 U.S. patents and 226 non-U.S. patents and employed about 30,000 people, roughly 25,000 of them in Asia. It is organized under the laws of Ireland.
