Vicor Corporation (VICR) | The Buildout — AI Infrastructure

The Verdict

Vicor designs and manufactures modular power components and power systems that convert electrical power. Its Advanced Products line implements Factorized Power Architecture, a proprietary approach that distributes power through individual components each optimized for one function. For the AI buildout, the key product is Vertical Power Delivery — the high-current, high-density conversion required at the point of load for advanced processors. Vicor also licenses its power-system intellectual property to OEMs and hyperscalers, and sells into industrial, aerospace and defense, and automotive markets. A legacy Brick Products line of integrated converters is being shrunk to free capacity.

Earnings Beat

Q2 2026 product and royalty revenue was $143.4M, up 26.9% sequentially and 1.6% year over year; the prior-year quarter included a $45M patent litigation settlement. Consolidated gross margin rose 280 basis points sequentially to 58%. Advanced Products revenue rose 45% sequentially to $94.2M, or 65.7% of revenue. One-year backlog rose 26% sequentially to $379.7M.

Management tone: Management beat its own Q2 revenue guide of nearly $126M with $143.4M and raised FY2026 guidance, and the call tone was confident. It held a conservative licensing assumption in guidance even after a new license closed in Q2. Versus the prior quarter, it reframed the second-generation VPD production ramp from before end-2026 to late Q3 or Q4 2027, described the precise first-fab capacity ceiling as yet TBD, and declined to identify licensees or confirm customer concentration.

Management Guidance

Management guided Q3 2026 revenue up nearly 10% sequentially and raised FY2026 revenue to over $600M from nearly $570M. It plans double-digit sequential increases in product revenue for Advanced Products and expects margin expansion as utilization and absorption rise. The most recent license is expected to contribute $5M in Q3 and $10M per quarter for the following four quarters, against a $60M total. The guidance assumes no new licensing agreements until the second ITC case reaches final determination in 2027.

Trajectory

Revenue went from $113.0M in Q1 2026, up 5.3% sequentially, to $143.4M in Q2, up 26.9% sequentially. The rotation is inside the mix: Advanced Products rose 45% sequentially to $94.2M while Brick Products rose 2.4%, and Advanced share went from 57.5% to 65.7%. Consolidated gross margin rose 280 basis points sequentially to 58% from 55.2%. Mix and higher royalty revenue — described as nearly 100% margin — explain much of that, while management says product gross margin was pressured by a one-time first-fab equipment move.

The Model

The model projects FY+1 revenue of $610.0M and EBITDA of $171M, a 28.1% margin, and FY+2 revenue of $927.7M and EBITDA of $316M, a 34.1% margin. The near term anchors on the raised FY2026 guidance, the royalty schedule of $5M in Q3 then $10M per quarter for four quarters, and double-digit sequential product growth in Advanced Products. The FY+2 step-up depends on second-generation VPD production ramps framed for late Q3 or Q4 2027 and on the second fab, which does not ramp until late 2027 or 2028.

Projections are the median of 5 independent model runs. The model’s revenue sits 3.3% below analyst consensus.

Management guided Q3 2026 revenue up nearly 10% sequentially and raised FY2026 revenue to over $600M from nearly $570M. It plans double-digit sequential increases in product revenue for Advanced Products and expects margin expansion as utilization and absorption rise. The most recent license is expected to contribute $5M in Q3 and $10M per quarter for the following four quarters, against a $60M total. The guidance assumes no new licensing agreements until the second ITC case reaches final determination in 2027.

What Could Go Right — and Wrong

Looking Ahead

Over the next 12 months the tests are revenue conversion, royalty timing, and capacity. Management guided Q3 2026 revenue up nearly 10% sequentially and FY2026 revenue over $600M, and plans double-digit sequential product growth in Advanced Products. Selected-customer engagement with second-generation VPD development systems and tools starts in Q3 2026, with production ramps framed for late 2027. The second fab is being built after two properties were purchased in September 2026, but it does not ramp until late 2027 or 2028.

The Company

Vicor designs, develops, manufactures, and markets modular power components and power systems that convert electrical power. Its Advanced Products line implements Factorized Power Architecture, a proprietary approach to distributing power through individual components each optimized to perform a specific function, and includes the PRM regulator, the VTM current multiplier, and modular current driver and multiplier units. Its AI role is Vertical Power Delivery for high-current processors, plus licensing its power-system intellectual property to OEMs and hyperscalers. A second line, Brick Products, is integrated power converters sold into conventional architectures; management treats it as legacy and aims to minimize its footprint.

Vicor runs a vertically integrated chip fab at its Andover, Massachusetts complex, a roughly 320,000-square-foot owned manufacturing building that houses all Massachusetts manufacturing activities, alongside a roughly 90,000-square-foot owned office. It also owns a roughly 31,000-square-foot Sunnyvale, California industrial building leased long-term to a corporate tenant. It sells through four authorized stocking distributors — Arrow Electronics, Digi-Key, Avnet Electronics, and Mouser Electronics — and describes a set of 100 customers across four markets: HPC, industrial, automotive, and aerospace and defense. Advanced Products mostly go direct or through contract manufacturers, while the distributor channel remains Brick-weighted.

Business Segments

Competitive Landscape

Management positions its second-generation Vertical Power Delivery as ahead of generation-one VPD and integrated voltage regulator alternatives, saying competitors are challenged to deliver on current gain and current density and that generation-one solutions are barely above 1 amp per square millimeter. It says the industry has no solution for projected requirements, while also acknowledging that IVRs offer flexibility and that Vicor could supply a building block for them. Vicor's filings do not name competitors, and no neighbor in the source material names Vicor.

Supply Chain

Vicor buys advanced semiconductor devices from wafer foundries and packaging partners, then sells power modules to AI, industrial, and defense systems makers. It owns its Andover fab but depends on unnamed foundries and packaging suppliers.
