VICR
Vicor Corp
Summary
What they do:
Designs and manufactures proprietary Factorized Power Architecture (FPA) power conversion modules that convert 48V bus power to sub-1V point-of-load power for GPUs and AI accelerators, sitting on the server motherboard as the last critical stage of voltage transformation before electricity reaches the processor die.
Why they matter:
As GPU power consumption scales past 1,000 watts per chip, Vicor's patented FPA and Vertical Power Delivery (VPD) architecture eliminates intermediate conversion stages, delivering higher density and efficiency than conventional multi-stage buck regulators — a physics advantage that grows more valuable with every GPU generation.
Recent performance:
FY2025 product revenue $350.3M (+12.1% YoY), total revenue $452.7M including $45M patent settlement, net income $118.6M ($2.61 EPS). Stock has surged from ~$39 to ~$218 over the past 52 weeks. Q4 book-to-bill above 1.2x with backlog at $176.9M.
Our Verdict
Emerging AI power play with proprietary 48V architecture riding the GB200/B200 ramp — AI exposure growing fast but stock has run 5x in 12 months, leaving valuation stretched ahead of Monday earnings.

Vicor Corporation is headquartered in Andover, Massachusetts, where it operates the world's first Converter-housed-in-Package (ChiP) fabrication facility — a 95,000-square-foot automated manufacturing plant that produces the power modules used in high-performance computing, aerospace, defense, and industrial applications. Unlike most semiconductor companies, Vicor is both a chip designer and a module manufacturer. The ChiP fab packages Vicor's power conversion silicon into compact, high-density modules that can be placed directly on server motherboards or even on top of GPU packages themselves.
The physical product is deceptively simple in appearance: small rectangular modules, typically 25mm x 12mm x 4mm, with thick copper pins on the underside. But each module contains proprietary power conversion circuitry that performs a specific function in Vicor's Factorized Power Architecture. A PRM (Pre-Regulation Module) takes unregulated 48V input and produces a regulated output. A VTM (Voltage Transformation Module) takes that regulated voltage and transforms it down to the sub-1V levels that GPU cores require, delivering hundreds of amps with microsecond transient response. By separating regulation from transformation — "factorizing" the power conversion — Vicor eliminates the efficiency losses that plague conventional multi-stage buck converters.
The company's most strategically important product line is Vertical Power Delivery (VPD), which places power conversion modules directly on top of or adjacent to the processor package. In a traditional server, power travels from the rack power supply through the motherboard traces to voltage regulators near the GPU, then through more traces to the GPU itself. Each centimeter of copper trace wastes energy and adds impedance. VPD shortens that path to millimeters, delivering power vertically through the package substrate. This matters because a GPU drawing 1,000+ watts at sub-1V requires over 1,000 amps of current — and at those current levels, even small resistance in the power path wastes tens of watts as heat. Vicor's Gen 5 VPD, launching in Q1 2026 for a lead customer, represents the next evolution of this approach.
Vicor generated $350.3M in product revenue and $57.4M in royalty/licensing revenue in FY2025, with advanced products (including VPD and FPA modules for AI/HPC) growing 26.6% to $248.6M. The company ended 2025 with $402.8M in cash and zero debt. It has approximately 44.65 million shares outstanding and a market cap near $9.7B at current prices around $218.

The Catch
Vicor's stock has run 5x in 12 months on the promise of Gen 5 VPD — but the product revenue growth rate was only 12.1% in FY2025, the lead customer for Gen 5 has not been publicly identified, and the CEO has sold over $25M in shares in the two weeks before Monday's earnings report. The company's moat is real but narrow: Vicor was designed out of NVIDIA's H100 in favor of MPS, proving that the world's most important GPU customer can and does choose alternatives. At ~85x trailing earnings, the stock is priced for a revenue inflection that has not yet appeared in reported numbers. If Monday's earnings show product revenue below $100M or if management tempers expectations on VPD ramp speed, the premium evaporates quickly — and there is no valuation floor at these multiples.
If They Win
If Vicor's Gen 5 VPD becomes the standard power delivery architecture for next-generation AI accelerators — if the lead customer ramp proves successful and multiple hyperscalers and GPU vendors adopt VPD for its physics advantages in delivering 1,000+ watts to processor dies — then Vicor transforms from a niche power module company into the essential last inch of power delivery for every AI processor on earth. Product revenue could scale past $1B by 2028, licensing revenue could compound as competitors are forced to license FPA patents, and the second ChiP fab would fill to capacity. The company's $400M cash position and zero debt provide the balance sheet strength to fund the expansion without dilution. In this scenario, the 5x stock run was early — not late.
