Why Seagate Technology Holdings Stock Is Back Under the Microscope

Seagate Technology Holdings (STX) is drawing fresh attention after its latest quarterly and full-year earnings, which showed higher revenue and net income alongside commentary tying performance to AI driven storage demand.

The company reported fourth-quarter sales of US$3.63b, compared with US$2.44b a year earlier. Net income for the quarter was US$1.29b, compared with US$488m, with diluted earnings per share from continuing operations at US$5.58 versus US$2.24.

For the full year to July 3, 2026, Seagate Technology Holdings reported sales of US$12.20b, compared with US$9.10b a year earlier. Net income was US$3.18b, compared with US$1.47b, and diluted earnings per share from continuing operations was US$13.90 versus US$6.77.

Management has also issued guidance for the fiscal first quarter 2027, targeting revenue of about US$4.1b, plus or minus US$100m. Alongside this, Seagate Technology Holdings affirmed a quarterly cash dividend of US$0.74 per share, payable on October 7, 2026 to shareholders of record at the close of business on September 24, 2026.

These figures sit against a share price of US$812.76 at the last close on August 5, 2026. The stock is down about 4.7% over the past day and down roughly 5.1% over the past week, while still up over the past year.

After a sharp run that has produced a very large 1 year total shareholder return of about 4.4x, Seagate Technology Holdings is now seeing momentum cool. The 1 month share price return is down 8.7% as the wider AI memory and storage group reacts to mixed guidance from peers like Western Digital and Sandisk and reassesses how quickly recent earnings strength and AI driven storage demand might translate into future cash flows.

Those inputs include forecasts for strong annual revenue growth, rising profitability and a future earnings multiple that is lower than the current P/E but still reflects a premium to a broad tech peer group.

Result: Fair Value of $1,115.87 (UNDERVALUED)

However, you still need to watch for HDD pricing optimism fading or AI storage spending patterns shifting, which could pressure Seagate Technology Holdings’ revenue and margin assumptions.

Another View: What Seagate’s P/E Ratio Is Telling You

The analyst narrative flags Seagate Technology Holdings as 27.2% undervalued relative to a US$1,115.87 fair value, yet the current P/E ratio of 57.9x tells a more cautious story. That is far above the Global Tech industry at 22.9x, the peer average at 28.9x, and even the 57.8x fair ratio.

In plain terms, the share price already embeds very strong expectations, with little gap between the current P/E and the fair ratio. That can leave less room for error if growth or margins land below the analyst script. Which valuation lens do you trust most when expectations are this high?
