This surge aligns with industry-wide gains, , both of which are also benefiting from rising demand for high-bandwidth memory (HBM) and DRAM.

A critical catalyst for Seagate’s performance was its announcement of a $500 million notes exchange agreement. The transaction, which involved converting $500 million in 3.5% exchangeable senior notes into approximately $503.4 million in cash and additional shares, provided immediate liquidity while signaling confidence in the company’s equity.
