Shares of Vicor Corporation (VICR) surged 18.39% in after-hours trading following the company's release of its third-quarter 2025 financial results, which significantly exceeded analyst expectations. The power components maker demonstrated robust performance, particularly in its licensing revenue segment.

Vicor reported earnings per share (EPS) of $0.63 for the quarter ended September 30, 2025, marking a substantial increase from $0.26 in the same period last year.

CEO Dr. Patrizio Vinciarelli highlighted the company's success in licensing revenue, which reached a record rate in Q3. He expressed optimism about Vicor's IP licensing practice, stating, "As high density power systems pioneered by Vicor, including NBMs and VPD, are on the critical path of high performance computing, I expect Vicor's IP licensing practice to grow substantially." This positive outlook, coupled with the strong financial results, appears to be driving investor enthusiasm and the significant after-hours stock price increase.
