SEC filings, insider trading & institutional ownership from EDGAR.
Seagate Technology is a leading provider of data storage technology and infrastructure solutions, with hard disk drives (HDDs) as its principal product, complemented by solid state drives (SSDs), solid state hybrid drives (SSHDs), storage subsystems, and edge-to-cloud storage solutions marketed under its Lyve portfolio, which includes data transfer shuttles, a storage-as-a-service cloud offering, and the open-source Cortx object storage software. The company designs, manufactures and markets storage products across two broad categories: mass capacity storage—serving nearline applications for hyperscale data centers and cloud computing, video and image applications (VIA), network-attached storage (NAS), and edge-to-cloud infrastructure—and legacy markets, including consumer, mission critical enterprise, and client applications such as desktops, notebooks, DVR storage, and gaming systems. Its product portfolio spans SATA, SAS, and NVMe interfaces, with enterprise nearline HDDs shipping up to 20TB, enterprise SSDs up to 15TB, and various systems including modular storage arrays, JBODs, and expansion shelves for data center infrastructure.
Seagate is vertically integrated, designing and manufacturing critical components such as read/write heads and recording media in-house, while sourcing other components like spindle motors and glass substrates from third parties, and outsourcing certain manufacturing (including printed circuit board assemblies) to contract manufacturers; assembly and manufacturing operations are located in China, Thailand, Malaysia, Northern Ireland, Singapore, and the United States. The company's customers include major original equipment manufacturers (OEMs), large hyperscale data center companies, cloud service providers (CSPs), distributors, and retailers, with branded consumer storage products sold under names such as Seagate Ultra Touch, One Touch, Expansion, Basics, and LaCie, and partnerships with brands like Microsoft Xbox, Sony PlayStation, and Disney's Star Wars and Marvel franchises. Seagate operates in a data storage industry driven by exponential growth in global data creation—forecasted to grow from 84 zettabytes in 2021 to 221 zettabytes by 2026—fueled by trends such as 5G, IoT, artificial intelligence, machine learning, cloud migration, video analytics, and edge computing, positioning the company to serve markets ranging from enterprise and cloud infrastructure to consumer electronics and gaming.
