Seagate, Western Digital Shares Fall on Report of Toshiba HDD Expansion
Summary
Shares of hard drive makers Seagate and Western Digital fell sharply following a report that rival Toshiba plans a major investment to double its production capacity, aiming to capture a larger share of the growing AI data center market.
Shares of hard drive manufacturers Seagate Technology (NASDAQ: STX) and Western Digital (NASDAQ: WDC) plummeted on Friday after a report detailed competitor Toshiba's plan to significantly expand its production capacity to target the growing demand from artificial intelligence data centers.
Toshiba's Expansion Plan
According to a report from Nikkei, Toshiba intends to invest approximately ¥60 billion ($400 million) to double its hard disk drive (HDD) production capacity by fiscal 2027. The expansion will reportedly focus on the company’s factory in the Philippines and is aimed directly at supplying the storage-intensive needs of AI infrastructure.
The HDD market is an oligopoly dominated by three companies: Seagate, Western Digital, and Toshiba. This investment signals Toshiba's ambition to significantly alter the market landscape.
Intensifying Competition
The news sparked investor concerns about increased competition and potential pricing pressure in the concentrated HDD sector. Toshiba, which currently accounts for just over 10% of the market based on capacity, has set a medium-term target of reaching a 30% share, according to the Nikkei report.
AdAn aggressive expansion by Toshiba could disrupt the current market dynamics, giving major customers like hyperscalers and data-center operators more supply options and greater negotiating power. This could potentially erode the market share and margins of the two current leaders.
Market Reaction
The sell-off was sharp, with Seagate shares falling 11% and Western Digital dropping 7% in Friday's trading. The negative reaction comes after a period of massive gains for both stocks this year, which had left them vulnerable to profit-taking on any news that could challenge the industry's favorable supply-demand outlook.
Prior to the decline, Seagate shares had gained roughly 240% this year, while Western Digital had risen about 170%. Shares of SanDisk (NASDAQ: SNDK), which also has exposure to the data-storage market, fell about 1%.
