Western Digital’s operating results make a credible bullish case: FY2026 revenue, margins and free cash flow rose sharply, while the company reported strong cloud demand and began shipping next-generation hard drives of up to 40TB. But those facts do not show that WDC stock is undervalued. Without a current share price and valuation analysis, “buy aggressively” is not a conclusion the available evidence can support.
What Western Digital is today
Western Digital Corporation, branded WD and traded on Nasdaq as WDC, is now focused on hard disk drives (HDDs). Its continuing operations comprise one reportable HDD segment, with products sold under the Western Digital and WD brands. The company serves three end markets: Cloud, Client and Consumer.
WD completed the separation of its Flash business on February 21, 2025, creating Sandisk Corporation as an independent public company. Sandisk’s post-separation business and results should not be treated as part of WD’s current operating story.
- Cloud: Storage solutions for cloud customers; this is WD’s largest and fastest-growing end market.
- Client: HDD solutions for OEM and channel customers, including desktop and notebook applications.
- Consumer: External HDD storage sold through retail and channel partners.
What WD’s latest reported results show
WD’s fiscal year ended July 3, 2026. The figures below are company-reported results, not forecasts. Non-GAAP measures are not interchangeable with GAAP results.

| Period and measure | Reported figure | Comparison or context |
|---|---|---|
| FY2026 revenue | $12.919 billion | Up 36% year over year |
| FY2026 gross margin | 48.9% GAAP; 49.1% non-GAAP | FY2025 gross margin was 38.8% GAAP and 39.4% non-GAAP |
| FY2026 non-GAAP operating income | $4.817 billion | Up 107% year over year |
| FY2026 non-GAAP free cash flow | $3.511 billion | Up 145% year over year |
| Q4FY26 revenue | $3.747 billion | Up 44% year over year and 12% sequentially |
| Q4FY26 gross margin | 54.1% GAAP; 54.4% non-GAAP | Company-reported quarter result |
| Q4FY26 non-GAAP diluted EPS | $3.56 | Up 109% year over year |
| Q4FY26 free cash flow | $1.281 billion | Company-reported quarter result |
The results point to both growth and improved profitability: revenue climbed while gross margin expanded, and the company generated substantial free cash flow. They do not establish how much of that performance is sustainable, or what investors are already paying for it.
Read the Q4 GAAP and non-GAAP figures separately
WD reported Q4FY26 GAAP net income attributable to common shareholders of $3.195 billion, while its non-GAAP diluted EPS was $3.56. The company’s Q4 GAAP statement included $1.684 billion of interest and other income. Those figures use different measures; the unusually high GAAP net income should not be read as a straightforward measure of recurring operating earnings. Investors comparing earnings over time should examine the company’s reconciliations and the composition of non-operating items rather than treating GAAP net income and non-GAAP EPS as equivalent.
What management expected for Q1FY27
On August 5, 2026, WD guided to Q1FY27 revenue of $4.1 billion, plus or minus $100 million; non-GAAP gross margin of 55% to 56%; and non-GAAP diluted EPS of $4.00, plus or minus $0.15. These were management’s estimates, not reported results. WD said it provides guidance on a non-GAAP basis because some items are difficult to estimate or depend on future events.

The guidance indicated that management expected further growth and margin expansion after Q4FY26. It should be assessed as a dated forecast, not substituted for actual Q1FY27 performance.
How much of the growth case depends on cloud and AI
WD attributes storage demand to long-term cloud growth and AI and hybrid-data workloads. The company’s Q4FY26 investor presentation showed Cloud at approximately 89% of revenue, with Client and Consumer each around 5% to 6%, across the five quarters displayed. The mix makes cloud infrastructure spending central to the investment case, but also leaves WD exposed to the purchasing decisions of a concentrated group of large customers.
WD reported 231 nearline exabytes shipped in Q4FY26, compared with 190 in Q4FY25. Its presentation also reported 22 non-nearline exabytes in Q4FY26, compared with 20 in Q4FY25. These are company-reported shipment metrics; they indicate growth in shipped storage capacity, not by themselves the profitability or future pace of demand.

CEO Irving Tan said in WD’s August 5, 2026 results release that the company’s Q4 results reflected its ability to scale innovation and operational execution to support customers’ growing storage demand. CFO Kris Sennesael described FY2026 as a year of broadening demand and deeper customer engagement, and expressed confidence in long-term growth, further margin expansion and free cash flow. These statements explain management’s view; they are not independent confirmation that AI demand will translate into a particular level of future revenue or earnings.
What is shipping, and what remains a roadmap target
Capacity announcements matter, but a product in qualification, one entering production, one being shipped and a long-range capacity target are different milestones. WD’s February 2026 announcement and Q4FY26 presentation described the following stages:
| Technology or milestone | Status described by WD | How to interpret it |
|---|---|---|
| Next-generation ePMR drives up to 40TB per drive | The Q4FY26 presentation said WD had started shipping them. | A company-reported shipment milestone, not proof of shipment volume, yields or margins. |
| 40TB UltraSMR ePMR | In February 2026, WD said this drive was in qualification with two hyperscale customers and that volume production was planned for the second half of 2026. | Qualification and planned production were forward-looking milestones in that announcement; the later presentation separately reported shipping next-generation ePMR drives up to 40TB. |
| HAMR | WD said qualification was underway with two hyperscale customers, with ramp production described for 2027. | A planned ramp, dependent on qualification and execution—not an already established high-volume product. |
| HAMR capacity scaling to 100TB | WD’s February 2026 roadmap targeted scaling to 100TB by 2029. | A long-range company target, not a capacity already shipping. |
WD also announced High Bandwidth Drive and Dual Pivot technologies, a power-optimized HDD and an intelligent software/API platform concept for AI customers. The company said these technologies could improve bandwidth, I/O performance or power use for selected workloads. Those are vendor claims and development statements; the evidence here does not include independent comparative tests.

How buybacks, dividends and debt affect the case
WD’s FY2026 Form 10-K reported that it repurchased 14.7 million shares for $2.59 billion during the fiscal year and had $3.26 billion remaining under its repurchase program as of July 3, 2026. It reported FY2026 cash dividends of $0.50 per common share. On August 4, 2026, the company declared a $0.15-per-share dividend, payable September 17 to shareholders of record September 8.
Repurchases can reduce the number of shares outstanding and dividends return cash to shareholders, so both can affect per-share outcomes. Neither establishes that the shares are undervalued: a buyback’s value depends in part on the price paid, while a dividend does not remove operating or valuation risk.
The capital-allocation picture also includes financing. WD used retained Sandisk shares in transactions to reduce debt and reported that it no longer held Sandisk shares as of July 3, 2026. The filing reported $710 million aggregate principal amount of 2028 convertible notes outstanding at fiscal year-end. Convertible debt brings potential dilution as well as repayment obligations; assessing shareholder returns requires considering debt and share count alongside buybacks and dividends.

What could weaken the bullish thesis
WD’s filings and results release identify risks that directly test the growth and margin story. The company does not quantify the probability or financial impact of each risk in the cited disclosures.
- Customer concentration and spending cycles: A few large cloud buyers could slow orders, delay qualification or negotiate for lower prices. Volatile demand, macroeconomic conditions, inflation, interest rates and recession could also affect investment in storage infrastructure.
- Pricing and competition: Competition or weaker pricing could limit the benefit of higher capacity and strong shipment demand.
- Technology and manufacturing execution: New products must be developed, qualified and produced at scale. Higher-capacity drives or HAMR could take longer, cost more or face yield, supply or manufacturing constraints than expected.
- Supply and customer commitments: WD cites dependence on a limited number of qualified suppliers and the effects of long-term agreements. Supply-chain delays or changes in customer relationships could interfere with planned growth.
- Financial and operational risks: The company also identifies debt, cybersecurity, international conflicts and the possibility that dividends or repurchases could be reduced or discontinued.
These risks matter because the optimistic case depends not only on end-market demand, but on WD converting that demand into qualified products, reliable supply, attractive pricing and sustained cash generation.
What would show that the market is wrong?
Strong results show that WD’s business improved in FY2026; they do not show that the stock is mispriced. Establishing that the market underestimates future results requires comparing a current share price with a defensible view of normalized earnings and free cash flow. The company figures cited here do not provide a current valuation, peer comparison or independent consensus estimate, so they cannot substantiate a claim that WDC is undervalued now.
For an investment decision, test the bullish thesis against the price and the assumptions embedded in it. In particular, compare:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- WD’s HDD exposure with other storage investments’ exposure to HDDs or flash, keeping Sandisk separate after the 2025 split.
- Cloud and hyperscaler revenue concentration, rather than treating AI-related demand as evenly spread across customers and end markets.
- Capacity actually shipped and technologies qualified against future production plans and roadmap targets.
- Gross-margin expansion and free-cash-flow conversion across more than a single strong quarter or fiscal year.
- Customer commitments and pricing visibility, including the effects of long-term agreements.
- Debt, potential share dilution, dividends and repurchases together.
- Valuation against normalized earnings and cash flow, not just a recent growth rate or a single quarter’s results.
On the operating evidence, WD had a strong FY2026 and a credible opportunity tied to cloud storage growth, with a substantial execution and customer-concentration risk. That supports investigating the stock, not an unconditional recommendation to buy aggressively. The valuation question remains unresolved until the share price and sustainable earnings and cash-flow assumptions are assessed.
