Though Seagate Technology Holdings plc (NASDAQ:STX)’s revenue for the third quarter of 2025 has reached a 31% year-on-year increase, the sequential growth shows a 7% decline owing to temporary supply constraints arising from geopolitical tensions. Proportionately, the mass capacity shipments were also down, but by 5%. Seagate Technology Holdings plc (NASDAQ:STX) continues struggling to manage the operational issues that previously affected its performance. For the fourth quarter, the company anticipates a negative performance that closely follows the customer buying decisions, which is expected to be impacted by potential tariffs and Fed rate cuts.
