Approach 2: Seagate Technology Holdings Price vs Earnings

For a profitable company, the P/E ratio is a useful way to think about what you are paying for each dollar of current earnings, which helps you compare opportunities across the market using a common yardstick.

What counts as a "normal" or "fair" P/E depends on how fast earnings are expected to grow and how risky those earnings are. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually points to a lower multiple.

Seagate Technology Holdings is trading on a P/E of 88.58x, compared with the wider Tech industry average of 23.66x and a peer group average of 42.60x. Simply Wall St’s Fair Ratio for Seagate, based on its earnings growth profile, industry, profit margin, market cap and risk factors, is 77.50x. This Fair Ratio is designed to be more tailored than a simple peer or industry comparison because it adjusts for company specific characteristics rather than relying only on broad group averages.

Comparing the current P/E of 88.58x with the Fair Ratio of 77.50x suggests the stock is trading above what this framework would view as a fair multiple.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Seagate Technology Holdings Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives on Simply Wall St take the story you believe about Seagate Technology Holdings, link it to a forecast for revenue, earnings and margins, and turn that into a Fair Value that you can compare with the current price. Each Narrative lives inside the Community page, updates automatically when new earnings or news arrives, and can reflect very different views, such as a bullish Seagate Narrative that points to a Fair Value around US$1,096.35 and a more cautious one closer to US$375.00. This allows you to quickly see which story most closely matches your own expectations and whether you think the stock is priced above or below what you consider reasonable.

For Seagate Technology Holdings, however, we will make it really easy for you with previews of two leading Seagate Technology Holdings Narratives:

Start with the bullish case if you think the market is still underappreciating what the AI storage cycle and margin story could mean over the next few years. Then contrast it with a more tempered view that leans on consensus forecasts and a Fair Value that sits closer to, or below, where the stock is trading today.

Fair Value in this bullish Narrative: US$1,096.35 per share

Implied undervaluation vs last close of US$931.04: about 15.1% below this Fair Value

Assumed annual revenue growth: 37.51%

  • Assumes AI-driven data growth, next-generation HAMR-based Mozaic drives and regulatory data retention trends support higher revenue, wider margins and a larger storage footprint for Seagate over time.
  • Models a ramp in earnings from US$2.4b to US$16.0b by 2029 with profit margins rising from 21.6% to 55.8%, and a future P/E of 22.9x applied to those earnings.
  • Highlights risks from faster adoption of flash and SSDs, customer consolidation, potential environmental compliance costs and shifts in cloud storage architectures that could challenge this optimistic path.

Fair Value in this more cautious Narrative: US$847.68 per share

Implied overvaluation vs last close of US$931.04: about 9.8% above this Fair Value

Assumed annual revenue growth: 30.37%

  • Builds in strong AI and cloud storage demand and the ramp of Mozaic HAMR drives, but anchors forecasts closer to analyst consensus on revenue, margins and earnings.
  • Projects revenue rising to US$24.4b and earnings to US$10.9b by 2029, with margins at 44.7% and a future P/E of 25.9x, implying the stock is roughly in line with, or slightly above, what this group views as fair.
  • Calls out trade policy, debt levels, tax changes, supply constraints and competition from SSD and NAND technology as factors that could limit how much of the AI storage theme ultimately flows through to shareholders.

Once you have a sense of which Narrative feels closer to your own expectations on growth, margins and risk, you can use that as a reference point against the current share price rather than reacting only to recent returns or headlines.
