Intel shares fell 4% after the chipmaker issued disappointing first-quarter guidance that overshadowed its fourth-quarter earnings beat. The company reported adjusted earnings of $0.15 per share on $13.7 billion in revenue, both exceeding analyst estimates. However, its outlook for the current quarter fell short, projecting breakeven earnings per share versus expectations of $0.05.

CFO David Zinsner cited supply constraints, noting available supply would be at its lowest level in Q1 before improving in the second quarter. The company's Data Center and AI segment grew 9%, but its largest Client Computing Group revenue declined 7% year-over-year. For the full year 2025, Intel posted flat revenue of $52.9 billion.

CEO Lip-Bu Tan highlighted progress on its Intel 18A process technology, calling it a milestone for U.S.-based manufacturing. The company launched its first AI PC platform built on this technology, expecting it to power over 200 designs from global manufacturers. Investors now watch for execution on supply improvements and market share recovery.
