Intel Falls 21.8% After Weak Q1 Guidance Despite Sixth Straight Q4 Beat

INTCINTC

Intel stock fell 21.8% to $42.49 after issuing weak Q1 FY2026 guidance. While Q4 results beat estimates for a sixth straight quarter, weak Q1 outlook and supply constraints pressured gross margins, and custom ASIC business grew 50% to a $1B run rate.

1. Sharp Stock Decline Driven by Disappointing Q1 Outlook

Over the four weeks ending January 22, 2026, Intel shares fell by 21.8%, reflecting investor concern after management’s Q1 FY’26 revenue guidance of $12.6 billion to $13.6 billion missed the $14 billion consensus. Adjusted EPS guidance of $0.20 to $0.30 also trailed analyst estimates of $0.45. Intel cited ongoing supply constraints at its fabs, limiting its ability to meet strong demand for client and data-center CPUs. This marked the first quarter in over two years that Intel’s guidance failed to match the sell-side consensus, leading to a near-term technical breakdown and elevated implied volatility in options markets.

2. AI PC Opportunity Pushed by Core Ultra Series 3

Intel’s launch of its Core Ultra Series 3 processors, built on its 18A node, positions the company to capture a segment of the AI-enabled PC market forecast to reach $25 billion by 2026. To date, over 200 distinct laptop and desktop designs featuring these chips have been announced, representing an estimated design win ratio above 30% among major OEMs. First-Principles Partners projects that AI PC revenue could contribute as much as $3 billion in incremental sales by year-end, helping Intel to narrow the margin gap with competitors in the client segment and underpinning a bullish long-term rating based on improving unit economics.

3. Custom ASIC Growth and Foundry Capacity Constraints

In 2025, Intel’s custom ASIC business grew by more than 50%, exiting the year at an annualized $1 billion run rate thanks to demand for networking and AI fabrics. Strategic partnerships with Ericsson and Amazon Web Services to produce 5G SoCs and AI accelerator chips on Intel’s 18A process have begun feeding incremental foundry revenue. However, limited wafer supply remains a bottleneck: Intel operated fabs at near-100% utilization in Q4 2025, prompting management to defer scaling of its next-generation 14A node until firm external commitments materialize. CEO Lip-Bu Tan has indicated that customer qualification for 14A will be a prerequisite for capital deployment, with supply agreements expected to be finalized in the back half of 2026.
