On October 6, Seagate Technology PLC fell 3.16% in pre-market trading, trading at $861.5/share, with Turnover of $49.72 million. The decline follows reports that Seagate and Toshiba are competing to acquire TDK's hard-disk drive magnetic-head business, raising concerns over potential multi-billion-dollar capital expenditure and integration risks.

According to the reports, Seagate submitted a higher bid in the summer after Toshiba initiated negotiations in the spring, with the deal potentially valued at several billion dollars. TDK is the only independent supplier of HDD magnetic heads, serving Seagate, Toshiba, and Western Digital, meaning the winner would control a critical link in the HDD supply chain. The prospective large-scale acquisition expenditure, combined with recent executive share sell-offs, has put pressure on Seagate's near-term valuation.
