Western Digital (WDC) Stock Prediction: $725 Bull vs $290…

The popular WDC stock prediction this month starts from the wrong premise: that Western Digital “crashed on record earnings” because the AI storage trade is finished. The tape says otherwise. On 6 August, the day after WD beat its own guidance, the stock fell 13.0% to $451.52 while Seagate, which supplies nearline hard drives to the same hyperscalers, rose 1.8%. That was not a verdict on storage demand. It was a verdict on Western Digital relative to its main competitor, and it explains why WDC closed at $460.93 on 10 September, 38% below its highest close of $746.23 on 18 June, while Seagate sits just 21% below its own peak (stockanalysis.com daily closes, 10 September 2026).

Here is what most coverage misses. Strip out the noise and the “discount” has almost closed. Both companies guided September-quarter revenue to exactly $4.1bn. Annualise the guided non-GAAP EPS and WDC trades at 28.8 times ($4.00 x 4) against Seagate’s 29.5 times ($7.30 x 4). The drawdown removed a premium, it did not create a bargain. Two more traps sit in the numbers: trailing GAAP EPS of $24.28 includes a $6.5bn gain on the retained SanDisk stake, so screens showing a 19x trailing multiple are flattering the stock (the non-GAAP figure is $10.22, or 45x), and the $2.59bn WD spent on repurchases in fiscal 2026 did not shrink the diluted share count, which held at roughly 385-388 million as convertible notes were settled in stock.

Why WDC stock is 38% below its June high

The slide came in two distinct legs, and they have different causes. The first, from the 18 June peak to mid-July, hit the whole memory and storage complex at once. On 26 June WDC fell 13.2% and Seagate 12.2%; on 16 July WDC dropped 9.2%, Seagate 10.0% and SanDisk 12.6%. When four names with different products and pricing cycles fall together, the driver is positioning, not fundamentals. After a year in which WDC rose from $95.02 to a June peak nearly eight times higher, the crowded trade simply unwound.

The second leg is the one that matters for the forecast, because it was specific to Western Digital. WD reported fiscal fourth-quarter results after the bell on 5 August. Revenue of $3.75bn and non-GAAP EPS of $3.56 beat the consensus of roughly $3.69bn and $3.33 cited by Proactive via Yahoo Finance on 6 August. Guidance pointed to September-quarter revenue growth of 42% to 49%. The stock still fell 13.0% the next day while Seagate gained. The reason was the gross-margin guide of 55%-56%, which the market compared directly with Seagate’s.

That comparison is harsh because Seagate is further along the HAMR (heat-assisted magnetic recording) curve, the technology that pushes a single drive past 40 terabytes and cuts cost per terabyte. Seagate has already built its Mozaic product line around HAMR. WD’s own 44-terabyte HAMR drive is scheduled for the first half of calendar 2027. In the meantime WD is leaning on a 40-terabyte ePMR drive, which began shipping in the June quarter, and on UltraSMR, which it expects to make up about 60% of nearline exabytes as it exits fiscal 2027.

Since then the stock has traded in a range of roughly $434 to $536 on a closing basis, with the latest move a 4.4% drop on 10 September. Pre-market on 11 September it was indicated at $463.00 at 4:11 a.m. New York time (stockanalysis.com). This forecast anchors on the $460.93 regular-session close, not the pre-market indication.

The social conversation has not caught up with the distinction. A scan of the past 30 days of social posts found mostly YouTube explainers titled in the “crashed on record earnings” mould and thin Reddit threads, consistent with a retail audience treating the drop as a demand scare. Coverage was partial (no X, TikTok or Instagram results), so treat that read as directional.

What Western Digital and Seagate are saying

Management’s message on the call was that demand is not the problem and pricing is getting better, not worse. “As global data creation continues to accelerate, we enter fiscal year 2027 with continued confidence in the durability of demand and with increasing visibility into our business,” said Irving Tan, Chief Executive Officer at Western Digital, in the 5 August results release.

The pricing detail came from the finance chief. According to Kris Sennesael, Chief Financial Officer at Western Digital, speaking on the fiscal Q4 call, “the blended average year-over-year price increase per terabyte improved from high single digits last quarter to high teens this quarter.” That is the single most important number for the bull case. WD shipped 231 exabytes in the quarter, up 22%, so revenue grew faster than volume because each terabyte sold for more.

The first question on that call went straight to the margin gap. “It’s hard not to compare your results with your main competitor, where they’re seeing better sequential top-line growth and targeting gross margins nearly 200 basis points higher than your September guide,” said CJ Muse, analyst at Cantor Fitzgerald. Tan’s reply was that “there are always quarter-to-quarter variations in terms of gross margin,” pointing to the timing of long-term agreement (LTA) renewals and the ramp of new drive platforms.

On visibility, Tan was more concrete: “We are very much in the throes of discussions with customers to establish LTAs for calendar year 2029, 2030, and 2031 as well.” Long-dated contracts cut both ways. They lock in volume, but they also lock in price, which caps the upside if spot pricing keeps climbing.

Seagate’s framing a week earlier was aimed at exactly the technology gap investors are pricing. “Seagate is well positioned to address strengthening exabyte demand through our Mozaic platform and differentiated HAMR technology roadmap,” said Dave Mosley, Chair and Chief Executive Officer at Seagate, on 28 July.

The demand side still looks intact. Alphabet lifted its 2026 capital expenditure forecast to $195bn-$205bn from $180bn-$190bn on 22 July, and “We’re still in a supply-constrained environment,” Anat Ashkenazi, Chief Financial Officer at Alphabet, told analysts. Supply was already tight a year ago: TrendForce reported in September 2025 that nearline HDD lead times had stretched from a few weeks to over 52 weeks.

WDC vs Seagate: the numbers behind the discount

The chart shows both legs of the drawdown and where the three scenario levels sit against the June peak.

Set side by side, the two companies look far more alike than the 17-percentage-point gap in their drawdowns suggests. WD actually printed the higher gross margin last quarter. What Seagate has is a higher earnings run-rate per share and an earlier HAMR ramp.

Two other numbers shape the valuation. At 360.5 million shares outstanding on 7 August (per the 10-K cover), WD’s market value at $460.93 is about $166bn. On fiscal 2026 free cash flow of $3.51bn that is a 2.1% yield; on the June quarter’s $1.28bn annualised, about 3.1%. That is not cheap for a hardware supplier, which is why the bear case below does not need a demand collapse to work. For the memory side of the same trade, see our Micron (MU) bull and bear levels and the SanDisk (SNDK) forecast, the flash business WD spun off in February 2025.

The structural tension: concentration, converts and the SSD threat

Three structural issues sit under the headline numbers, and each one feeds a different scenario.

Customer concentration. Cloud was 89% of fiscal 2026 revenue, the top 10 customers 73% and three customers 44% between them, according to the 10-K. That is up from 55% for the top 10 in fiscal 2024. Pricing power with a customer who takes 16% of your output is real only as long as supply stays tight. If one hyperscaler pauses to digest the drives it has bought, WD has little diversified demand to fall back on.

The share count. Having tracked WD’s capital structure since the SanDisk separation, the pattern worth flagging is that repurchases are mostly offsetting convertible dilution rather than shrinking the company. Basic shares rose from 339.0 million in January to 360.5 million in August, mainly because a June exchange of $858m of 2028 convertible notes was settled with $860m of cash and 21.3 million shares. The 26 August exchange added another 4.65 million shares. Diluted shares were about 388 million in the June quarter and are guided at about 388 million again. The good news is the balance sheet: WD has now used its entire SanDisk stake (28.8 million shares at the spin) to retire debt and repurchase stock, and ended fiscal 2026 with $1.58bn of cash, no long-term debt and $1.05bn of borrowings classified as current, including $350m drawn on a revolver that matures in January 2027.

Substitution. TrendForce’s September 2025 note warned that the HDD shortage was pushing cloud providers to test high-capacity QLC SSDs for cold data, which offer about 30% lower power consumption. For now cost per terabyte keeps hard drives in the cold tier, but every quarter of 52-week lead times gives cloud customers a reason to redesign around flash. Our coverage of the NAND price ceiling at Kioxia and SK Hynix tracks the other side of that substitution trade, and our list of stocks that could be the next SanDisk covers the names benefiting from it.

Capital spending is also turning up. WD said fiscal 2027 capex will be higher than fiscal 2026’s $418m as it invests in heads, media and automation, though Sennesael said in his prepared remarks that more exabytes from new platforms “does not require spending CapEx to add unit capacity.” Supply discipline is the whole bull case, so any sign that either HDD maker is adding unit capacity would be the clearest warning.

WDC stock prediction: bull, base and bear cases

All three scenarios use the same method: an estimate of fiscal 2028 (year ending mid-2028) non-GAAP EPS multiplied by the multiple the market is likely to pay for it 12 months from now. The starting point is WD’s own guide of $4.00 for the September quarter. The FinanceFeeds base path puts fiscal 2027 EPS at about $18 ($4.00, then roughly $4.40, $4.70 and $5.00), assuming pricing and the 40-terabyte ramp keep margins rising in line with guidance.

Base case: $550 (+19%), probability 45%

Fiscal 2028 EPS of about $22 at 25 times. That assumes revenue grows around 20% in fiscal 2028 as exabyte growth runs at the 25%-plus rate Tan described, price per terabyte rises more slowly than the current high-teens pace as LTAs reset, and operating margin drifts into the high 40s. The multiple compresses modestly from today’s 28.8x run-rate as growth normalises. The result sits back inside the range WDC traded through in late July and early August.

Bull case: $725 (+57%), probability 25%

Fiscal 2028 EPS of about $26 at 28 times. This needs three things at once: price-per-terabyte gains staying in the high teens or better through calendar 2027, the 44-terabyte HAMR drive shipping on schedule in the first half of calendar 2027, and gross margin moving toward 60% so WD closes the gap with Seagate. On about 375 million diluted shares, $26 implies roughly $9.75bn of net income, which fits a revenue base near $23.5bn at a 50% operating margin. Even then, $725 remains just below the 18 June highest close.

Bear case: $290 (-37%), probability 30%

EPS stalls around $16, close to today’s run-rate, and the multiple falls to 18 times. The route there is not a demand collapse. It is pricing peaking as long-dated LTAs lock in lower escalators, a hyperscaler digesting inventory, HAMR slipping into late 2027 while Seagate keeps ramping, and faster QLC substitution at the cold tier. At $290 the market value would be about $105bn, a free-cash-flow yield of roughly 5% on a $5.5bn fiscal 2027 estimate, a yield that would price in very little growth beyond fiscal 2027.

The probability-weighted value is about $516, 12% above the $460.93 close. The bull target is above spot and the bear target below it, as required. The skew is positive but narrower than the chart suggests, because the base case assumes margin gains WD has guided but not yet delivered.

Invalidation. The bull case is off the table if the December-quarter gross-margin guide, due with fiscal Q1 results, comes in below 55%, or if management moves the HAMR launch beyond the first half of calendar 2027. The bear case weakens sharply if WD guides December-quarter gross margin at 57% or higher and confirms signed LTAs running to 2031 with price escalators intact.

What would change my mind. A narrowing of the gross-margin gap with Seagate for two consecutive quarters would push me toward the bull case. Evidence that either HDD maker is adding unit capacity, or that a top-three customer is moving cold storage to QLC flash at scale, would push me toward the bear. For a sense of how the server side of the same AI build-out is being priced, compare our Dell bull and bear case.

Frequently asked questions

What is the WDC stock prediction for the next 12 months?

FinanceFeeds sets a base case of $550, 19% above the $460.93 close on 10 September 2026, with a $725 bull case and a $290 bear case. The base case assumes fiscal 2028 non-GAAP EPS of about $22 valued at 25 times. The probabilities are 45% base, 25% bull and 30% bear, which produces a probability-weighted value of roughly $516.

Why did Western Digital stock fall after beating earnings?

WD beat revenue and EPS expectations for its fiscal fourth quarter and guided higher, but its September-quarter gross-margin guide of 55%-56% sat below what Seagate was implying. Investors read that as a sign WD is behind in HAMR drive technology. The stock fell 13.0% on 6 August while Seagate rose 1.8%.

Does Western Digital still own shares in SanDisk?

No. WD kept 28.8 million SanDisk shares at the February 2025 separation and has now used all of them. It swapped shares to cut debt in June 2025 and February 2026, then exchanged the final 1.7 million SanDisk shares for 4.8 million of its own shares in the June 2026 quarter. That stake produced a $6.5bn gain that inflates fiscal 2026 GAAP EPS.

How does WDC compare with Seagate (STX)?

Both guided $4.1bn of September-quarter revenue. WD posted the higher June-quarter non-GAAP gross margin at 54.4% against Seagate’s 52.7%, but analysts on WD’s call said Seagate is targeting margins nearly 200 basis points above WD’s guide, and Seagate is further along its HAMR ramp. On annualised guided EPS, WDC trades at 28.8 times and STX at 29.5 times, so the valuation gap is smaller than the drawdown gap suggests.

When does HAMR matter for Western Digital?

WD says its 44-terabyte HAMR drive will ship in the first half of calendar 2027, with 50-terabyte products following in the second half. Until then it relies on 40-terabyte ePMR drives and UltraSMR. Any slip in that schedule would be the most direct threat to the margin catch-up that the base and bull cases assume.

Does Western Digital pay a dividend?

Yes. The board declared a quarterly dividend of $0.15 per share, payable on 17 September 2026 to holders of record on 8 September. At $460.93 that is a yield of about 0.13%. Most shareholder returns come through repurchases, which totalled $2.59bn in fiscal 2026.
