Why is Vicor stock surging today?
Vicor Corporation's stock rose 12.3% after hours after raising its Q3 2026 revenue growth guidance from nearly 10% to over 20%, driven by royalties from its VPD licensing program. Four major companies have licensed the technology, and the CEO noted potential supply disruptions for unlicensed suppliers. The company also recently authorized a $150M share buyback and acquired properties for AI-driven demand. The Nasdaq closed at a record high, led by AI stocks, but broader indices were unchanged.
