Vicor (VICR) stock came into focus after the company reported second quarter 2026 results, with revenue of US$143.35 million and net income of US$49.77 million, alongside higher earnings per share compared with the same period a year earlier.

Despite reporting higher revenue and net income, Vicor’s latest earnings update coincides with a share price that is down 8.8% over one day and 35.5% over the past month, while still showing a very large 1 year total shareholder return. This suggests that recent momentum has faded following a strong run.

So with Vicor sliding hard after reporting higher revenue and earnings, yet still trading at a sizeable discount to analyst targets, is the market being prudently cautious or overly harsh on the valuation?

Most Popular Narrative: 48.1% Undervalued

Vicor’s most followed narrative pegs fair value at $406.25 versus the last close of $211.01, which frames the recent share price slide in a very different light.

The accelerated adoption of high-power, high-density AI computing in data centers is driving demand for advanced power delivery solutions. Vicor's Gen 5 vertical power delivery products and 800V-to-48V converters target this need, with customer engagements and sampling set to expand in Q3 and Q4. These next-gen products enable Vicor to address a market expected to exceed $5 billion by 2027, supporting long-term revenue growth and eventual margin expansion as manufacturing scales.

Curious what sits behind that fair value gap for Vicor? The narrative leans heavily on steep revenue compounding, firm margins and a rich future earnings multiple. The specific growth path, margin profile and discount rate are all spelled out in detail.

Result: Fair Value of $406.25 (UNDERVALUED)

However, Vicor’s narrative still faces pressure from a book to bill ratio below 1 and heavy reliance on unpredictable, litigation-driven licensing income.
