Intel shares plunged more than 20% in late trading on Thursday after the chipmaker issued a fourth-quarter revenue forecast that fell well short of Wall Street expectations, a miss driven by a memory chip shortage that is squeezing PC demand and by supply problems in its data centre business. The reaction was sharp because it contrasted with a strong third quarter and with investor optimism that had more than doubled the stock this year on expectations of AI-driven gains.
Intel said it expects fourth-quarter revenue of $15B to $16B, below the $17B analysts had expected on average. It also forecast adjusted earnings of 25 cents a share, compared with estimates of 43 cents. The gap between guidance and consensus was wide enough to reset near-term expectations for a company that has been trying to convince investors its turnaround is gaining traction.
Key facts at a glance
- Fourth-quarter revenue guidance: $15B to $16B, versus about $17B expected.
- Adjusted earnings guidance: 25 cents a share, versus 43 cents expected.
- Third-quarter revenue: $16.5B, up 21% from a year earlier.
- Data centre and AI sales: $7.3B, up 78%.
- PC chip sales: $8.1B, down 5%.
- PC market outlook: a 12% contraction this year and another 10% decline in 2027.
- Stock reaction: shares fell more than 20% in late trading.
The headline number obscured a more complicated split inside Intel. The company’s third quarter was strong by several measures: revenue rose 21% to $16.5B, data centre and AI sales jumped 78% to $7.3B, and PC chip sales slipped 5% to $8.1B. That followed the fastest growth in more than a decade in the prior quarter. Yet the forward guide suggested that the forces supporting demand for AI infrastructure are not enough to offset pressure in the PC supply chain and disruptions in the data centre unit.
A memory shortage becomes a PC problem
PC makers are struggling with a shortage of memory chips, a component that is essential to every laptop and desktop and that has become more expensive as AI data centres absorb available supply. The shortage has pushed up prices and cut demand for PCs, according to industry research cited in the market reaction. PC manufacturers have reached the limit of what they can pay for memory, one research firm said in September, leaving them with few options beyond raising system prices, reducing configurations or slowing shipments.
Memory is a critical part of the PC bill of materials, and when DRAM and NAND prices rise sharply, the effect travels quickly through the channel. Notebook makers typically operate on thin margins, so a sustained increase in memory costs can force them to adjust product mix, postpone promotions or pass costs to consumers. In a market already sensitive to weak consumer spending, those moves can soften demand further. Intel, as a leading supplier of PC processors, sits at the center of that chain: weaker PC builds mean weaker orders for its chips, even if its processor share remains strong.
Intel expects the PC market to shrink 12% this year and another 10% in 2027. That outlook implies that management does not see the memory squeeze as a one-quarter event. The shortage has been building as memory manufacturers allocate capacity toward higher-value products used in AI servers, including high-bandwidth memory and server DRAM. That shift supports the AI buildout but tightens the supply of conventional memory used in client devices. For PC makers, the result is a cost shock at a time when demand was already uneven.
“Memory pricing went up a lot. I think my prediction is that in 2027 it is going to be a very severe issue to all of us,” chief executive Lip-Bu Tan said. The comment framed the shortage as an industry-wide problem rather than a company-specific misstep. It also explained why Intel’s PC chip outlook could remain under pressure even if processor demand itself is stable. When memory is scarce and expensive, the constraint is not necessarily the CPU; it is the ability of PC makers to assemble and sell complete systems at acceptable prices.
Data centre growth meets supply friction
The data centre business offered a contrasting picture. Sales in the segment jumped 78% to $7.3B, reflecting strong demand for servers and AI infrastructure. But Tan said the unit would have done better without shortages of some raw materials and a factory shutdown in Israel. Those operational issues matter because data centre customers plan capacity far in advance, and any delay in supply can shift revenue between quarters or open the door to competitors.
Intel has been trying to rebuild its position in data centre processors while also expanding into AI accelerators, a market where Nvidia has a dominant position and AMD has been gaining share. The company’s manufacturing strategy is central to that effort. Under Tan, Intel has been restructuring operations, cutting costs and seeking to prove that its advanced process technologies can attract external customers as well as support its own products. Supply disruptions at a time of rapid AI demand are therefore more than a logistical nuisance; they can affect customer confidence and the credibility of the turnaround.
The fourth-quarter guide also implies a sequential decline from the third quarter. Intel reported $16.5B in revenue for the third quarter and guided to $15B to $16B for the fourth, a range that brackets a meaningful step down. The company attributed the outlook to the memory shortage hitting PC demand and to supply problems slowing the data centre unit. For investors, the question is whether those constraints are temporary bottlenecks or signs that the recovery will be more uneven than expected.
Why the stock reaction was so severe
The stock had more than doubled this year as investors bet Intel would gain from AI. That rally raised expectations, making the company vulnerable to any sign that the AI opportunity would not translate into near-term financial results. A revenue guide below consensus and an earnings guide well below estimates gave investors a reason to reassess the pace of improvement. The late-session drop of more than 20% reflected both the size of the guidance miss and the high bar created by the stock’s earlier run.
Intel is also in the middle of an expensive turnaround. The company recently sold $15B in shares to fund its efforts under Tan, adding capital for manufacturing, research and restructuring. A large equity raise can strengthen the balance sheet, but it also puts more focus on execution: investors want to see that the capital is being deployed into businesses that can grow and defend market share. The memory shortage and data centre supply issues are exactly the kind of operational tests that can shape confidence in that plan.
The wider industry context helps explain the tension. AI spending has been concentrated in data centres, where memory makers, chip designers and server builders are competing for limited capacity. PC demand, by contrast, is more cyclical and more sensitive to component prices. When memory supply tightens, the PC market can weaken even if the broader technology economy is growing. Intel’s outlook captures that split: strong AI-related data centre sales on one side, and a PC business constrained by memory costs and cautious OEM purchasing on the other.
For PC makers, the memory shortage has become a planning problem. They must decide whether to absorb higher component costs, reduce memory configurations, delay launches or raise prices. Each choice has trade-offs. Lower configurations can hurt performance and customer satisfaction; higher prices can depress unit demand; delays can leave older inventory in the channel. Those decisions feed directly into processor orders, which is why Intel’s PC chip revenue can weaken before end-user demand fully reflects the cost increase.
Intel’s guidance also lands against a backdrop of intense competition. In PCs, the company faces rivals that are pushing alternative architectures and trying to win share in notebooks and desktops. In data centres, customers have more choices than ever for general-purpose processors and AI acceleration. A supply-constrained quarter does not erase Intel’s incumbency or its manufacturing ambitions, but it gives competitors an opening to deepen relationships with customers who need predictable delivery.
The third-quarter results show that Intel still has meaningful growth engines. Data centre and AI sales of $7.3B represented a sharp increase and underscored how much demand exists for compute infrastructure. Total revenue of $16.5B, up 21%, was a sign that the company can grow even while managing a complex transition. The problem is that the fourth-quarter guide shifts attention from that growth to the constraints that could limit it.
Intel’s shares had more than doubled this year before the late-session decline, reflecting investor bets that the company would benefit from AI and from Tan’s turnaround plan. The company recently sold $15B in shares to fund that plan, giving it more room to invest while it navigates the memory shortage and the data centre supply disruptions. The next few quarters will test whether those constraints are manageable bottlenecks or a deeper drag on the recovery.
