One capacity expansion announcement from Toshiba (TSHTY) is shaking up the storage trade, putting hard disk drive (HDD) makers under pressure while the broader memory group barely moves. Seagate Technology (STX) is taking the biggest hit, with shares tumbling nearly 10.2% Friday, the sharpest decline among storage stocks. After artificial intelligence (AI) data center demand turned Seagate into one of the year’s standout technology performers, Toshiba is now looking to grab a bigger piece of the same booming market.
According to reports, Toshiba plans to double its HDD supply by investing roughly $380 million in the Philippines to expand production and support a more stable supply of components needed for AI infrastructure. The expansion would mark the Japanese company’s first major HDD investment in about five years, while the company is also developing products aimed at increasing memory capacity per unit.

With the added output targeting storage demand from AI data centers, the same customers driving Seagate’s surging results, the competitive threat is getting harder to ignore. So, with Toshiba stepping up its HDD ambitions, should investors be worried about Seagate’s next move? More importantly, is the sharp selloff a warning sign or a potential opportunity?
About Seagate Stock
Seagate Technology is a global data-storage company founded in 1978. Headquartered in Fremont, California, Seagate specializes in developing and manufacturing mass-capacity data-storage solutions, with hard disk drives (HDDs) at the core of its business. The company serves a wide range of customers, including cloud service providers, hyperscale data centers, enterprises, and consumers, with its storage products playing an increasingly important role in supporting the growing data needs of AI infrastructure.
Seagate’s offerings include high-capacity HDDs, storage systems, and other data-storage solutions designed for applications such as cloud computing, enterprise storage, backup, archiving, gaming, personal computing, video surveillance, and content creation. The company also provides storage solutions for AI-enabled data centers and edge applications, positioning it to benefit from the rapid growth in data generation and the resulting demand for high-capacity storage.
Seagate’s stock has been on a remarkable winning streak, as explosive AI-driven demand for massive data storage has fueled a sharp improvement in the company’s financial performance and profitability. As AI data centers generate and process ever-growing volumes of information, demand for high-capacity storage has surged, giving Seagate a powerful growth catalyst and turning the stock into one of the year’s standout technology performers.
The market has clearly taken notice. Currently valued at a market capitalization of about $201.72 billion, Seagate shares have soared 252% over the past year and gained another 188% so far in 2026, dramatically outpacing the broader S&P 500 Index ($SPX). By comparison, the index is up just 15.8% over the past year and 13.6% in 2026. The stark performance gap highlights just how strongly investors have rewarded Seagate for its exposure to the booming AI-driven storage market.

Seagate closed out fiscal 2026 with a major surge in profitability, fueled by sustained data-center demand and successful execution of its heat-assisted magnetic recording (HAMR) technology roadmap. In its fiscal fourth-quarter results released on July 28, the storage giant reported $3.63 billion in revenue, representing a massive 48.5% year-over-year (YoY) increase and comfortably beating Wall Street’s $3.49 billion estimate.
Non-GAAP earnings per share came in at $5.71, topping analysts’ forecast of $5.09 and soaring 121% from the year-ago period. Margins provided another major highlight. Seagate’s non-GAAP gross margin jumped to 52.7%, crossing the 50% mark for the first time in recent memory and sharply improving from 37.9% a year earlier.
The company said its strong fourth-quarter performance exceeded expectations for both revenue and non-GAAP EPS, capping a fiscal year 2026 in which annual revenue grew 34%, while profitability and free cash flow reached record levels. Seagate Chairman and CEO Dave Mosley attributed the performance to robust cloud data center demand and disciplined execution, adding that the company expects this momentum to continue into fiscal 2027. Seagate also delivered a strong cash-generation performance.
During the fiscal fourth quarter, the company generated $1.3 billion in cash flow from operations and $1.1 billion in free cash flow. For the full fiscal year, operating cash flow reached $3.7 billion, while free cash flow totaled a record $3.1 billion. The company returned $810 million to shareholders through dividends and share repurchases, while simultaneously strengthening its balance sheet by reducing total debt by $302 million during the fourth quarter and $1.4 billion during fiscal 2026.
Seagate ended the year with $3.6 billion in total debt and $1.7 billion in cash and cash equivalents. Looking ahead, Seagate expects the momentum to carry into fiscal 2027. For the first quarter of fiscal 2027, management projects revenue of $4.1 billion, plus or minus $100 million, while adjusted EPS is expected to land between $7.10 and $7.50.
How Do Analysts View STX Stock?
While investors seem spooked by Toshiba’s expansion plans, Wall Street is far from intimidated. Shares of the data storage maker jumped almost 4.5% on Monday after several Wall Street research desks pushed back against concerns over a looming capacity glut, arguing that the previous session’s selloff was overdone. The bullish updates came after Seagate suffered a sharp drop in the prior session following reports that Toshiba plans to double its hard-drive manufacturing capacity in the Philippines by fiscal 2027. That said, investors didn't entirely buy that argument the next day as STX stock sank a little over 9%.
Bernstein stood by its “Outperform” rating, calling the market’s reaction misunderstood, while Citi argued that the HDD industry is currently under-shipping demand by a wide margin. Citi analyst Asiya Merchant also pointed out that Toshiba relies on third-party suppliers for media and recording heads, creating potential bottlenecks that could limit how quickly the company can ramp up production.
Adding another dose of optimism, Goldman Sachs analyst James Schneider named Seagate a top tactical chip pick ahead of earnings, forecasting 2% upside to revenue and 3% upside to guidance, driven by stronger hard-drive pricing and progress in heat-assisted magnetic recording (HAMR) technology. In other words, Wall Street sees Toshiba’s capacity plans as a manageable challenge, not the immediate threat investors feared.
Despite the recent volatility, Wall Street is still firmly in Seagate’s corner. STX stock holds a consensus “Strong Buy” rating, with 21 of the 26 analysts covering it giving the “Strong Buy” rating. Another analyst has a “Moderate Buy” rating, while only four recommend “Hold,” underscoring the strength of the Street’s conviction. And the upside targets are just as striking.
The average price target of $1,143.48 suggests Seagate could gain another 42%, while the Street-high target of $1,600 points to a potential 99% rally from current levels. With most analysts still expecting significant upside, Wall Street appears to view the recent pullback as a bump in the road rather than a reason to abandon the Seagate story.
