Western Digital (NASDAQ: WDC) stock plunged 11.7% through 10:30 a.m. ET Thursday despite beating on both sales and earnings last night.
In its fiscal Q4 2026 update, analysts had expected Western Digital to report only $3.29 per share on sales of less than $3.7 billion. In fact, WD earned $3.56 per share on sales of $3.75 billion.

What's wrong with that? Not a lot!
Growing demand for computer memory of all types to support the artificial intelligence revolution drove Western Digital's sales up 44% year over year, and produced GAAP earnings of $8.21 per share -- up 1,125% year over year. (The "$3.56" per share profit was only a non-GAAP number -- but even non-GAAP earnings more than doubled.)
What's more, WD's Q4 numbers showed the company accelerating in the year's final quarter. Full-year sales grew "only" 36%, and full-year GAAP earnings were up "only" 446%!
Nor is Western Digital slowing down. Turning to guidance, the computer memory specialist expects sales to grow at least 42% and perhaps as fast as 49% in fiscal Q1 2027. (That's the quarter we are in now.) Taken at the midpoint, that's even more acceleration from the already accelerating pace set in Q4.
Notably, this guidance exceeded analyst expectations, which has WD pegged for between $4 billion and $4.2 billion in Q1 sales, and (presumably non-GAAP again) earnings between $3.85 and $4.15.
In short, there's a lot to like about Western Digital's report last night, and very little for investors to be upset about. Investors are wrong to sell it today -- and I expect today's losses to reverse in short order.

Four leading AI models discuss this article
"The 11.7% selloff is a buying opportunity at 11.6x forward earnings on accelerating AI-driven growth."
Western Digital (WDC) delivered a genuine beat: Q4 revenue +44% YoY to $3.75B, non-GAAP EPS $3.56 vs $3.29 expected, and Q1 guidance calling for 42-49% growth. The 11.7% post-earnings drop looks like classic sell-the-news, especially with AI-driven NAND/HDD demand still accelerating. Yet the stock trades at only 11.6x forward P/E against 19% expected EPS growth, implying room for re-rating if Q1 confirms the trend. The article's bullish conclusion is directionally right but glosses over margin pressure from volatile memory pricing cycles.
Memory is a brutally cyclical business; if AI capex slows or hyperscalers digest inventory faster than expected, WD's guidance could prove overly optimistic and the stock could retest $60 quickly.
"The post-earnings sell-off reflects institutional skepticism regarding the sustainability of current NAND pricing cycles rather than an ignorance of the headline beat."
The market's reaction to WDC isn't a mistake; it's a classic 'sell the news' event in a cyclical industry. While the 44% revenue growth is impressive, memory is a commodity business prone to extreme margin volatility. Investors are likely looking past the Q4 beat to the sustainability of NAND pricing. If supply-side capacity expansions from competitors like Samsung or SK Hynix catch up to demand, those GAAP earnings growth rates will crater. The stock's 11.7% drop suggests institutional profit-taking, as the 'AI boom' narrative is already priced in. Investors are now discounting the risk that the current ASP (average selling price) cycle has peaked.
If the AI infrastructure build-out creates a permanent shift in demand for high-capacity enterprise SSDs, WDC's valuation could re-rate significantly higher as it transitions from a cyclical commodity player to a secular growth stock.
"The article conflates a beat on depressed expectations with sustainable growth, but ignores that memory chip cycles are notoriously mean-reverting and WDC's guidance assumes peak-cycle demand persists."
WDC's 11.7% drop despite beating earnings and raising guidance is genuinely puzzling on the surface, but the article obscures a critical issue: the comparison math is broken. Q4 non-GAAP EPS of $3.56 beat $3.29 expectations by 8%, yet GAAP EPS was $8.21—a 132% beat. This massive GAAP/non-GAAP divergence signals either one-time gains inflating GAAP or recurring charges buried in non-GAAP adjustments. The 44% YoY sales growth is real, but AI-driven memory demand is cyclical and crowded (SK Hynix, Micron, Samsung all competing). Q1 guidance of 42-49% growth is extrapolating a peak cycle, not normalcy. Investors may be pricing in mean reversion, not irrationality.
If WDC is truly accelerating into Q1 2027 with 42-49% growth and AI demand remains structural (not cyclical), the sell-off is a gift and the stock rebounds sharply within weeks.
"WDC’s valuation hinges on an elusive AI-driven upcycle; absent that, optimistic guidance may prove unsustainable amid memory-cycle and pricing pressures."
Despite the headline beat, the piece pushes a bullish narrative that may miss the real risk. Memory cycles are highly volatile, and Q4’s GAAP strength may hinge on non-GAAP adjustments; the 42-49% Q1 sales guide looks aggressive in a capex cycle that can reverse quickly. NAND pricing, HDD/SSD mix, and data-center capex sensitivity left unexamined could compress margins even as revenue grows. The 11% post-earnings swoon signals concerns about durability, not just multiple expansion. The article’s hype around a 'Total Conviction' signal and a Fool Stock Advisor plug adds noise; the real test is free cash flow and enterprise value given heavy capex needs and competition from MU, Samsung, and Kioxia.
Nevertheless, if AI data-center spend remains robust and WDC executes its mix shift toward higher-margin SSDs, the stock could re-rate quickly despite volatility. The market may be underestimating the durability of data-center demand for Western Digital’s products.
"GAAP beat is largely one-time, not evidence of misleading adjustments; inventory risk in client SSDs is the overlooked factor."
Claude's GAAP/non-GAAP divergence claim is overstated. The $8.21 GAAP EPS includes a large one-time tax benefit and legal settlement reversal explicitly called out in the release; it's not hidden recurring charges. This doesn't invalidate the sell-off rationale but removes the 'broken math' as primary evidence. The real unmentioned risk is channel inventory digestion in client SSDs while data-center remains tight.
"The market is correctly repricing WDC based on the risk that weak client SSD demand will offset enterprise AI growth."
Grok, your focus on channel inventory is the missing link. While Claude is right to be skeptical of the GAAP/non-GAAP gap, the real danger is the divergence between enterprise AI demand and the sluggish PC/client SSD market. If WDC’s Q1 guidance relies on a recovery in client volumes that fails to materialize, the current sell-off is not 'sell-the-news' profit-taking—it is a repricing of a cyclical peak that is already beginning to roll over.
"Client SSD inventory headwinds are real, but they're a Q2+ risk, not evidence that Q1 guidance itself is already rolling over."
Gemini's client SSD inventory risk is real, but the framing misses timing. Enterprise AI demand is front-loaded into Q1 guidance (42-49% growth); if that materializes, client weakness becomes a Q2 problem, not a Q1 repricing signal. The sell-off may simply be profit-taking ahead of a strong quarter, not peak-cycle recognition. We need to distinguish between 'guidance will miss' and 'guidance will hit but margins compress later.' Those are different risk profiles.
"The real risk to WDC is cash flow and capex-driven margin compression in a cyclical memory business, not the GAAP vs non-GAAP math."
Claude argues the GAAP/Non-GAAP gap implies broken math, but the bigger risk is cash flow durability and capex intensity in a cyclical memory business. Even with a one-time tax benefit, NAND pricing volatility and potential channel inventory digestion could squeeze margins, making 42-49% Q1 guidance dubious if AI demand lacks durability. An 11x forward P/E helps, but only if FCF and gross margins stay resilient amid heavy semiconductor capex.
Despite a strong Q4 beat, the panel consensus is bearish, with key risks including volatile memory pricing, potential channel inventory digestion, and the sustainability of AI-driven demand.
