These results will be discussed later today at 5:00 p.m. Eastern Time, during management’s quarterly investor conference call. The details for the call are below.

Revenues for the first quarter ended March 31, 2024 totaled $83.9 million, a 14.3% decrease from $97.8 million for the corresponding period a year ago, and a 9.5% sequential decrease from $92.7 million in the fourth quarter of 2023.

Gross margin, as a percentage of revenue, increased to 53.8% for the first quarter of 2024, compared to 47.6% for the corresponding period a year ago, and increased from 51.1% for the fourth quarter of 2023. Operating expenses increased to $44.0 million for the first quarter of 2024, compared to $36.1 million for the corresponding period a year ago, and increased sequentially from $40.0 million for the fourth quarter of 2023, primarily due to an increase in legal expenses.

Commenting on first quarter performance, Chief Executive Officer Dr. Patrizio Vinciarelli stated: “Q1 gross margins and operating expenses reflect a step up in royalty income and legal expenses relating to our campaign to assert Vicor Intellectual Property. Licenses to OEMs, giving access to patented power system technology from otherwise infringing suppliers, will complement future revenues from our 5G product line and ChiP foundry. These capabilities position Vicor ahead of demands for escalating current and power density, with superior performance and foundry capacity that anticipate market requirements.”

“As we confront challenges and pursue opportunities, 2024 will be seen as the year in which our product strategy, selective licensing of Intellectual Property and clarity of purpose secured Vicor’s future growth and profitability. We are pleased with our execution of this comprehensive vision.”
