Why is Vicor stock surging today?
Vicor Corporation's stock surged 10.8% in pre-market trading after raising its Q3 2026 revenue growth guidance to over 30% due to higher-than-expected royalties from its VPD technology licensing. This is the second guidance increase in ten days, driven by new AI OEM licensees. The stock reached $320.08, with CEO Patrizio Vinciarelli noting four major OEMs and hyperscalers have licensed the technology. The broader market had minimal impact on this move.
