Intel (INTC.US) Q3 revenue rises 21%, but weak guidance leads to over 20% plunge after hours

According to Woofun AI, Intel (INTC.US) suffered a severe market backlash after releasing its third-quarter 2026 financial report. Despite double-digit growth in revenue, the stock price plunged more than 20% in after-hours trading. The core issue was that fourth-quarter revenue and profit guidance fell far short of Wall Street expectations, and an incident at its Israel-based factory further exacerbated short-term supply and profit pressures.

The financial data released on October 29 shows that Intel's revenue for the quarter reached $16.51 billion, a 21% year-over-year increase; however, net profit fell 18% year-over-year to $3.32 billion, with diluted earnings per share at $0.60, down 33% year-over-year. Under the Non-GAAP measure, performance was relatively impressive: net profit reached $2.756 billion, soaring by 169% year-over-year; earnings per share were $0.52, up 126% year-over-year, outperforming previous market expectations of $0.40. In terms of gross margin, the GAAP measure was 43%, and Non-GAAP was 44.1%, up 4.8 and 4.1 percentage points year-over-year, respectively.

However, the strong Q3 performance failed to boost market confidence. The immediate trigger for the stock price crash was pessimistic fourth-quarter guidance. The company expects Q4 revenue to be only $15 billion to $16 billion, with Non-GAAP earnings per share as low as $0.25—significantly below Wall Street expectations of about $17.07 billion in revenue and $0.43 earnings per share. Before the report, Intel’s stock had already fallen 3.6% during regular trading on October 29, closing at $92.07; after the results and guidance, the after-hours loss quickly expanded to exceed 20%.

The business segments showed significant divergence. The Data Center & AI Division (DCAI) became the growth engine, with Q3 revenue reaching $7.318 billion, a 78% year-over-year surge; operating profit was $3.039 billion, more than triple last year’s $964 million, with an operating margin as high as 41.5%. In contrast, the Client Computing & Physical AI Division (CCPG) showed weakness, earning $8.097 billion, down 5% year-over-year; operating profit was $2.285 billion, below last year’s $2.694 billion, with an operating margin of 28.2%.

Woofun AI summarized that management provided detailed explanations of supply and demand dynamics. CEO Pat Gelsinger pointed out that although the PC industry faces short-term pressure, CPU demand remains robust. The current priority is to increase the supply of Xeon processors and strengthen the product portfolio and roadmap. CFO David Zinsner emphasized that the Q3 data center business achieved the company's strongest revenue growth in 15 years, with revenue, gross margin, and earnings per share all surpassing prior guidance. Supply remains a constraint, as server CPU demand growth has outpaced expansion of supply for some products. Intel is working to relieve Xeon supply bottlenecks by increasing factory output, improving yield, and shortening production cycles. On the product front, the next-generation Xeon processor, Diamond Rapids, is advancing for high-performance computing, AI inference, and enterprise workloads; Intel also showcased rack-level designs based on Xeon processors and the stand-alone GPU D Series for AI inference at OCP Global Summit.

The struggles of the PC market and the internal transaction structure of the foundry business further complicated the financial picture. Q3 PC chip revenue was $8.1 billion, down 5% year-over-year, below the market expectation of $8.98 billion. Zinsner expects the PC market slowdown to last at least into the first half of 2027, with rising memory chip prices lifting the prices of end devices and dampening consumer purchasing willingness. Q3 foundry revenue reached $6.697 billion, a 58% year-over-year increase, but this included a substantial internal elimination amount of $6.291 billion, representing manufacturing charges paid by other Intel product units to the foundry division. Deducting internal transactions, actual external foundry revenue was limited. In terms of profitability, the foundry division’s Q3 operating loss was $1.853 billion, narrower than last year’s $2.321 billion, but the operating loss margin remained high at 27.7%.

Advances in process technology are key to Intel's long-term competitiveness. Intel 18A has entered mass production, with the third-generation Core Ultra processor (Panther Lake) being manufactured at scale and using ASML's High-NA EUV lithography technology. The Xeon 6+ processor launched in Q2 this year was the first server-grade product built on the 18A process. Subsequently, Intel pushed forward the 18A-P and 14A process generations; 18A-P has entered risk production to optimize performance, power consumption, and thermal characteristics. Q3 saw the release of version 0.9 of the 14A process’s PDK (Process Design Kit), enabling potential customers to design and validate their chips. Intel expects customers to make 14A process selections successively from the second half of 2026 through the first half of 2027. In advanced packaging, Intel is promoting technologies such as EMIB-T and has partnered with Lens Technology to explore integrating glass processing with semiconductor packaging.

Capital expenditure has surged, highlighting the financial pressures of a heavy-asset business model. TD Cowen (TD.US) analyst Joshua Buchalter pointed out that EMIB-T advanced packaging technology is creating valuable external market opportunities, but the critical factor for foundry valuation remains winning large-scale front-end wafer manufacturing clients. Intel’s Q3 capital expenditure reached $4.219 billion, up from $2.956 billion a year earlier; cash flow from operating activities was $5.082 billion, and adjusted free cash flow was $1.639 billion.

The company revised its full-year 2026 capital expenditure target from $18 billion to $20 billion and plans to significantly increase investment in 2027, focusing on manufacturing equipment, cleanroom capacity, and substrate production. To support growth, Intel completed a public stock offering of about $23 billion in August, raising net cash proceeds of $22.617 billion. Unlike asset-light companies like Arm, Intel bears the burden of long-term manufacturing spending; if demand falls short of expectations, fixed asset investments will drag down profit margins. While Q3 Non-GAAP gross margin was 44.1%, the Q4 guidance is only 38%, a decline of 6.1 percentage points, reflecting the financial sustainability challenges of its expansion plans.

Ecosystem partnerships and the Israel factory incident are causing short-term impacts. In Q3, Intel announced a partnership with Oracle (ORCL.US) to expand Xeon processor use in Oracle Cloud Infrastructure (OCI), including for planned OCI X14 products based on Diamond Rapids. Meta’s Muse Spark Open has completed testing on the upcoming GPU D Series (codename Crescent Island) and Xeon platform. In the client arena, Intel collaborated with Google to launch the first Googlebook devices featuring third-generation Core Ultra processors, with participation from manufacturers like Acer, Asus, and Lenovo.

Additionally, Intel has partnered with AMD (AMD.US) to integrate x86 CPU optimizations for PyTorch into the oneDNN software library; and with SAP to link enterprise IT systems and operational technology, expanding physical AI applications in industrial scenarios.

However, these partnerships have not yet disclosed specific procurement amounts or the scale of long-term orders, and therefore cannot be directly booked as realized revenue. In terms of foundry external client outreach, there is still no official confirmation regarding Google’s custom TPU chips being manufactured by Intel or a potential collaboration with Nvidia. On the competitive front, Intel faces challenges from TSMC (TSM.US) in advanced process technology and customer relations, as well as from AMD and Nvidia (NVDA.US). At the same time, tech giants such as Microsoft, Google, Amazon, and Meta are developing their own chips to reduce dependency. In October, a blast at the Kiryat Gat factory in Israel halted production for about two weeks; this plant primarily uses Intel 10 process technology for data center chips. Zinsner stated the incident is expected to reduce Q4 revenue by about $300 million and gross margin by roughly 200 basis points.

The factory is scheduled to gradually resume production around the end of October, but inspection of damaged wafers is ongoing, and a similar impact on Q1 2027 revenue is expected. If the damaged wafers cannot be recovered, the impact may persist. Under Pat Gelsinger’s leadership, Intel needs to solve three main problems: increasing Xeon supply, controlling cost pressures, and converting 18A/14A technology into external orders. Q4 revenue guidance of $15 billion to $16 billion reflects short-term growth pressure, persistent PC market weakness through the first half of 2027, and recovery at the factory yet to be seen. Previously, Intel's share price had more than doubled since 2026, and the market is reassessing the company’s growth prospects and the financial requirements for manufacturing expansion.
