Seagate Technology (STX) fell 5.87% to $836.18 in morning trading as reports emerged that the company is in a competitive bidding war with Toshiba for TDK’s hard-drive magnetic heads unit. The stock opened with a -1.6% gap and continued to decline throughout the session amid heightened uncertainty over the potential acquisition. The move reflects investor concerns over the strategic and financial implications of the bid, as well as the broader competitive landscape in the hard-disk drive market.
What Happened
Seagate is reportedly in talks to acquire TDK’s hard-drive magnetic heads unit, a key component in the production of hard disk drives. The company is competing with Toshiba for the business, which could be worth several billion dollars. This development has sparked concerns among investors about the risks and costs associated with the acquisition, particularly given the intense competition in the sector. The stock’s decline came as reports circulated through multiple financial outlets, including Seeking Alpha, Barron’s, and Stocktwits News, each highlighting the potential impact of the bidding war. The uncertainty surrounding the deal’s outcome has led to a sharp selloff, with the stock hitting an intraday low of $824.29 before stabilizing slightly in late morning trading.
What The Data Shows
The stock has traded within a wide 52-week range of $209.00 to $1145.00 and currently has a market cap of $193.1B. Over the past eight sessions, it has declined 2.5% from $914.98 to $891.98. The current session saw a volume of 0.7 million shares, which is 0.1 times the 3-month average. The stock also printed eight fresh 52-week lows on October 6. Recent insider activity has been bearish, with 34 sales totaling $379.3 million disclosed in the last 90 days, including recent sales by CEO William Mosley and other executives.
What To Watch
The company has no upcoming earnings date in the near term. Investors should monitor the breadth of coverage and any further developments in the bidding war for TDK’s hard-drive unit, as well as any updates from Toshiba or TDK that could affect the outcome of the deal.

The threat also isn't immediate. Doubling exabyte production would take two years, Sankar said, pointing to the 12-month cycle time for wafers and assuming another 12 months that would be needed to build out production and install manufacturing equipment. He also noted that customers are seemingly "skeptical about [the] capacity ramp trajectory for Toshiba." The company has previously fallen short of some of its production targets.
