- $VICR surged roughly 12% after hours on September 21, reaching around $251 after the company sharply raised its Q3 2026 revenue outlook. - Vicor increased its Q3 sequential revenue growth guidance from roughly 10% to more than 20%, citing royalties from recently signed Vertical Power Delivery, or VPD, licenses as the primary driver. - According to $VICR's CEO, four leading OEMs and hyperscalers have now secured licenses to Vicor's power-system technology. - On September 17, Vicor announced another non-exclusive VPD license with a leading AI OEM, allowing that customer to procure VPD modules from suppliers other than Vicor as well. - VPD is designed to address the "last inch" limitations of lateral power delivery by delivering extremely high current density at low voltage to high-power AI accelerators. - Earlier on September 11, Vicor said Fab-1 utilization was approaching capacity and acquired sites in New Hampshire for ChiP Fab-2 and Fab-3, with initial Fab-2 deployment targeted in roughly one year.
