Western Digital (WDC) is back in the spotlight as tight hard disk drive supply meets heavy demand from AI workloads, with analysts highlighting improved earnings visibility, pricing power, and strong Nearline storage interest ahead of upcoming results.

Western Digital’s share price has surged recently, with a 45.54% 30 day share price return and a 113.49% year to date share price return, while its multi year total shareholder returns are several times higher and reflect strong momentum around AI driven storage demand and tight HDD supply.

With Western Digital trading around US$400 and recent returns running far ahead of the broader market, the key question now is whether the current valuation still leaves upside or if the share price already reflects years of future growth.

Most Popular Narrative: 25% Overvalued

The most followed narrative puts Western Digital’s fair value at $321, below the last close at $400.73, and builds that gap around ambitious earnings and margin goals tied to AI storage demand.

Bullish analysts are largely keying off the reiterated view that the $20 plus per share EPS figure is intended as a floor, not a peak, alongside a stated path to 50% plus gross margin and 40% plus EBIT. At the same time, the clustering of higher targets signals growing attention to how AI generated video and memory demand could feed into revenue mix and profitability over time.

Want to see how a double digit EPS floor, richer margins and a premium earnings multiple are stitched together into one story? The core assumptions about future revenue growth, profitability and the discount rate are all laid out, along with how long AI driven demand would need to hold up to support that valuation path.

Result: Fair Value of $321 (OVERVALUED)

However, there is still meaningful execution risk, with Western Digital heavily exposed to a small group of hyperscale customers and potential disruption from alternative storage technologies.

Another View: Cash Flows Paint A Different Picture

While the most popular narrative sees Western Digital as about 25% overvalued at a fair value of $321 versus a share price near $400, the SWS DCF model points the other way, with an estimate of future cash flow value around $524 and the stock trading below that level.
