Seagate Technology PLC surged 7.56% during the trading session, extending a powerful post-earnings rally as investors cheered the company's fiscal fourth-quarter results and an exceptionally bullish forward guidance that far exceeded Wall Street expectations.

The storage giant reported quarterly revenue of $3.629 billion, a 48% year-over-year increase that beat the consensus estimate of $3.485 billion. Adjusted earnings per share came in at $5.71, soaring 120% from a year earlier and topping forecasts by roughly 12%. Even more critically, the company guided for fiscal first-quarter revenue of $4.0–$4.2 billion, well above the Street's $3.75 billion estimate, with adjusted EPS of approximately $7.30 versus the $5.80 consensus. The blockbuster guidance reflects robust, sustained demand for mass-capacity storage driven by the artificial intelligence buildout.

Sentiment was further bolstered by a wave of analyst price-target hikes from firms including Citi, Barclays, JPMorgan, Wells Fargo, and Wedbush. A broader rally in memory and semiconductor stocks also provided a tailwind, as the sector benefited from positive AI spending commentary and expectations of persistent memory shortages. Seagate's strategic positioning in the AI-driven storage cycle, including the ramp of HAMR technology and locked cloud data center capacity through 2028, underscored the company's long-term growth narrative.
