    After a share price that has already moved sharply on AI enthusiasm and guidance updates, the real test for Vicor now is simple: does the current valuation still leave enough upside to justify the risks you would be taking on?

    Most Popular Narrative: 41.5% Undervalued

    Vicor's most followed narrative pegs fair value at $406.25 per share, well above the last close of $237.62. This immediately raises questions about what kind of growth profile is being assumed to justify that gap.

    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.
