Vicor Corporation Common Stock (VICR) fair value

ACCE thesis

Vicor designs and sells high-density DC-DC power modules and the Factorized Power Architecture that brings high-voltage power close to the processor, a niche that matters most in AI accelerator racks where power delivery is now a binding constraint. Its moat rests on proprietary packaging and patented converter topology, which lets it sustain a 60.6% gross margin and a 36.6% operating margin that most hardware peers cannot approach. Revenue growth of 78.5% is the near-term driver, as hyperscale and AI server customers qualify Vicor modules into next-generation rack designs. At a trailing P/E of 46.0 and a forward P/E of 29.0, the market is already paying for continued expansion, so the question for a deeper look is whether order conversion and capacity keep pace with that growth. The stock has no index membership, which may leave it under-owned relative to its size of $8.1B.
