Recent fundamentals and profitability trends

According to the same Pluang overview, Seagate has beaten EPS estimates in recent quarters, and the company is expected to deliver EPS of USD 7.34 in its third quarter of fiscal 2026, reinforcing the view that recent earnings momentum is not a one-off and that the current valuation is tied to a series of estimate beats.

Looking ahead, investors are already focusing on the next quarterly update. Tickeron notes that Seagate is expected to report its upcoming earnings on October 28, 2026, a date that will be watched closely to see whether the company can extend its pattern of revenue growth and EPS outperformance.

Stock level and market context

Seagate stock closed at USD 858.79 on Nasdaq as of September 18, 2026, marking a strong advance that reflects higher expectations for AI-related storage demand but also increases the importance of the October 28, 2026 earnings release for confirming the underlying growth story.
