These results will be discussed at 8:00 a.m. Eastern Time, during management’s quarterly investor conference call. The details for the call are below. Product and royalty revenues for the second quarter ended June 30, 2026 totaled $143.4 million, a 26.9% sequential increase from $113.0 million in the first quarter of 2026, compared to $141.0 million from product revenues, royalty revenues and a patent litigation settlement of $45.0 million for the corresponding period a year ago. Gross margin increased sequentially to $83.1 million for the second quarter of 2026, compared to $62.4 million for the first quarter of 2026, and decreased from $92.1 million for the corresponding period a year ago. Gross margin, as a percentage of revenue, increased to 58.0% for the second quarter of 2026, compared to 55.2% for the first quarter of 2026. Gross margin decreased from 65.3% for the corresponding period a year ago which included the aforementioned $45.0 million patent litigation settlement. Operating expenses increased sequentially to $48.2 million for the second quarter of 2026, compared to $45.5 million for the first quarter of 2026, and increased from $46.7 million for the corresponding period a year ago. Net income for the second quarter was $49.8 million, or $1.04 per diluted share, compared to net income of $20.7 million, or $0.44 per diluted share, for the first quarter of 2026 and net income of $41.2 million or $0.91 per diluted share, for the corresponding period a year ago. Cash flow from operations totaled $34.0 million for the second quarter, compared to cash flow used for operations of $(3.9) million in the first quarter of 2026, which included the impact of a $28.6 million payment of an award for past litigation, and cash flow from operations of $65.2 million for the corresponding period a year ago. Capital expenditures for the second quarter totaled $11.2 million, compared to $12.4 million for the first quarter of 2026 and $6.2 million for the corresponding period a year ago. Cash and cash equivalents as of June 30, 2026 increased 12.2% sequentially to approximately $453.6 million compared to approximately $404.2 million as of March 31, 2026. Backlog for the second quarter ended June 30, 2026 totaled $380 million, a 26% sequential increase from $301 million at the end of the first quarter of 2026, and increased 145% from $155 million for the corresponding period a year ago. Commenting on second quarter performance, Chief Executive Officer Dr. Patrizio Vinciarelli stated: “Rising demand across high-performance compute, automatic test equipment, and industrial, aerospace and defense applications is absorbing increased capacity within our first ChiP fab. As we get closer to full capacity utilization, we are taking steps toward a second fab for high current density 2nd Gen VPD ChiPs. AI OEMs and Hyper-scalers are at a loss dealing with the current density and PDN limitations of 1st Gen. VPD systems. The industry’s fixation with PoL regulators (replacing VRs, operating from 12V or 6V, with IVRs, operating from 1.8V) merely trades off one handicap (low current density) for another (low current gain). Feeding IVRs with a current multiplier is an incremental opportunity for Vicor. With its 2nd Gen VPD IP, Vicor is uniquely equipped to overcome the power system challenges standing in the way of future advances in TPUs, GPUs and Wafer Scale Engines.”
