Up 476% Over the Past Year, Can Vicor Stock Keep Climbing Through 2028?

Key Takeaways:

• Explosive Bookings: Vicor posted a book-to-bill above 2 in Q1 2026, with its one-year backlog jumping 70% sequentially to $300 million.
• Price Projection: Based on current assumptions, VICR stock could reach $469.32 by December 2028.
• Potential Gains: That target implies a total return of 78.3% from the current price of $263.16.
• Annual Return: Investors could see roughly 26.2% annualized growth over the next 2.5 years.

Vicor Corporation (VICR) is not a household name, but it makes something every AI data center desperately needs: power delivery technology that can push enormous amounts of current directly into next-generation chips. The stock has risen 477% over the past year as that need has become urgent.

Q1 2026 revenue hit $113 million, up 20% year over year. Management guided Q2 revenue to nearly $126 million and full-year 2026 revenue to nearly $570 million.

Those are not small numbers for a company that did just $94 million in Q1 last year. The backlog rising to $300 million with a book-to-bill above 2 tells you demand is outpacing what Vicor can currently ship.

What the Model Says for Vicor Corporation Stock

We analyzed Vicor through the lens of a dual-engine business: a fast-growing advanced power products company and an increasingly valuable IP licensing operation.

The core technology at the center of the bull case is Vertical Power Delivery, or VPD.

• Modern AI chips require enormous amounts of current at very low voltages — think delivering 2,000 amps at under one volt to a processor.
• Existing solutions can’t do this efficiently. Vicor’s second-generation VPD solution offers a current density of 3 amps per square millimeter and a current multiplication factor of up to 40x, all in a package just 1.5 millimeters thick.
• That combination — high current density, high current multiplication, extreme thinness — is what makes next-generation wafer-scale and chiplet-based AI processors work.
• Competitors who have copied Vicor’s first-generation design are running into physical limits that make scaling impossible.
• The lead customer — widely understood to be Cerebras Systems — is in a steep production ramp of its wafer-scale engine.
• Vicor’s second-generation VPD solution is expected to begin ramping with this customer before year-end, with additional HPC customers to follow as capacity allows.

The second engine is IP licensing.

• Vicor won its first ITC exclusion order, has a second ITC case targeting additional products, and
• CEO Patrizio Vinciarelli has suggested a third case is possible.
• Royalty revenue could grow to 50% of product revenue over time, management has said. That’s nearly 100% margin.
• A hyperscaler and multiple OEMs are already licensees, and management believes most major customers will eventually need a Vicor license as AI infrastructure scales.
• On capacity, Vicor has identified a path to expand its first fab from $1 billion to $1.5 billion in annual revenue support. A second fab is in planning, with Vicor now focused on existing buildings to accelerate the timeline.

Using a forecast of 35.9% annual revenue growth and 35.2% operating margins, with an exit P/E of 49.6x, our model projects VICR reaching $469.32 by December 2028. That’s a 78.3% total return, or 26.2% annualized.

The 49.6x P/E assumption sits below VICR’s current NTM multiple of 69.7x and its one-year average of 62.9x, reflecting reasonable compression as growth matures. Trailing EBIT margins are just 18.1%, so the 35.2% assumption requires substantial execution on both revenue scale and licensing income.

Our Valuation Assumptions

TIKR’s Valuation Model lets you plug in your own assumptions for a company’s revenue growth, operating margins, and P/E multiple, and calculates the stock’s expected returns.

Here’s what we used for Vicor Corporation stock:

1. Revenue Growth: 35.9%

Vicor Corporation grew revenues 26.1% last year off a low base, and full-year 2026 guidance of $570 million implies roughly 50% growth from 2025.

The 35.9% assumption reflects strong momentum through 2028 as the second-generation VPD ramps and licensing revenue builds, while acknowledging that hypergrowth rarely holds indefinitely.

2. Operating margins: 35.2%

Trailing EBIT margins are just 18.1%, but the business is still early in scaling.

Gross margins were 55.2% in Q1, pointing to strong underlying profitability.

As licensing income grows at near-100% margins and fixed costs get absorbed across higher revenue, 35.2% operating margins are achievable — but require execution.

3. Exit P/E Multiple: 49.6x

VICR currently trades at 69.7x forward earnings.

The model assumes compression to 49.6x — still a premium multiple, but closer to the five-year average of 50.6x.

For a business with a potential IP licensing tailwind and near-monopoly in VPD, some premium is warranted.

What Happens If Things Go Better or Worse?

Here’s how Vicor Corporation stock could perform under different scenarios by December 2031:

• Low Case: With revenue growing at 26% and net income margins of 30.8%, investors could see a total return of 106.7% (17.6% annually).
• Mid Case: At 28.9% revenue growth and 32.9% net income margins, the total return climbs to 182% (26% annually).
• High Case: If revenue grows at 31.8% and margins reach 34.6%, total returns could hit 274.5% (34.2% annually).

The wide range reflects genuine uncertainty about IP licensing timing, second-fab execution, and how quickly additional VPD customers ramp once capacity becomes available.

The low case still delivers strong returns.

The high case — driven by licensing scaling toward 50% of revenue — would be transformational.
