Vicor Corporation is one of the most underappreciated technology franchises in the public markets. Founded in 1981 by Dr. Patrizio Vinciarelli — an MIT-trained physicist who has run the company for 44 years and who remains CEO, controlling shareholder, and chief innovator — Vicor has spent four decades quietly inventing the architecture that now powers the most energy-intensive infrastructure build in the history of computing: the AI data center.

The company’s Factorized Power Architecture (FPA) and Vertical Power Delivery (VPD) technology solve a problem that no other company has cracked as elegantly: how do you deliver thousands of amperes of clean, stable power to a GPU or AI accelerator chip whose power consumption is doubling with each generation, in a package small enough to fit directly beneath the processor die?

In 2025, the market finally began to recognize what Vicor had been building. Revenue grew 26% to $453 million. Net income exploded from $6 million to $118.6 million. Free cash flow reached $119 million — a 338% increase. The stock rose roughly 543% over the prior 12 months. And yet, by our analysis, the story is in its early chapters, not its final ones.
