Royalties changed the math at Vicor overnight. After Monday’s close, the Andover, Massachusetts power-components maker told investors it now expects Q3 sequential revenue growth of more than 20%, up from a prior forecast of nearly 10%. The company cited royalties from a recently announced non-exclusive license to its Vertical Power Delivery technology as the driver. Shares closed Tuesday up roughly 9% to 10%. For a stock already up more than 40% over the prior two weeks, that is a market telling you it wants more of this.
The Business
Vertical Power Delivery addresses what Vicor calls the “last inch” problem: AI processors draw enormous current at low voltage, and Vicor holds patents on feeding that current vertically into the chip rather than across the board.
Vicor says its second-generation design delivers materially higher current density than first-generation approaches, and management has framed that gap as central to why OEMs and hyperscalers are turning to licensing.
Four companies have now secured licenses to the power system technology Vicor developed and patented, with some hyperscalers initially reaching out after their computing systems faced import bans for infringing on Vicor’s NBM patents. That is a coercive dynamic working in Vicor’s favor: license or face an import ban. CEO Patrizio Vinciarelli has been direct about it.
Why Wall Street Is Paying Attention
This is Vicor’s second license in four months. The first helped raise second-quarter guidance from $126 million to $142 million, and that quarter came in with revenue up 27% sequentially and backlog at a record $380 million, up 145% from a year earlier.
The CEO has confirmed four leading companies among OEMs and hyperscalers have secured licenses, and the four brokerages covering the stock rate it a buy, with a median price target of $387.50. That target is well above today’s price. Getting there requires the licensing engine to keep running.
What’s Driving the Opportunity
If additional hyperscalers and suppliers adopt licenses for Vicor’s technology, licensing revenue could become a stable supplement to its core product sales. The CEO has also suggested further import ban proceedings at the ITC could push more unlicensed users to the table.
New sites in New Hampshire are intended to support additional ChiP fabs and expand manufacturing capacity beyond what Vicor has in Andover, as the existing ChiP fab approaches its utilization limit. Royalties scale without factory constraints. Hardware does not.
What Could Go Wrong
The bull case rests on assumptions that are easier to believe today than to guarantee in October. At roughly $10.4 billion of market value, Vicor trades near 22 times trailing revenue. Management’s stated revenue objective is $2.5 billion, more than five times current trailing sales, and the CEO has acknowledged that reaching it requires a second fabrication facility that does not yet exist.
The insider selling picture is not reassuring at these levels. Insider activity over the past 12 months shows heavy selling with no insider buying, with total shares sold valued in the high hundreds of millions of dollars. When the people who know the company best are consistent sellers into every rally, that matters.
The undisclosed terms of licensing agreements, the risk that licensees favor cheaper suppliers, and patents that rivals will keep testing remain key concerns. Royalty rates described by management as low by design could disappoint if Wall Street is modeling something richer.
The Bottom Line
Vicor has done something genuinely rare: it quantified a licensing pivot in a single quarter, doubled expected sequential growth, and demonstrated that its patent portfolio has real economic teeth. The technology is differentiated, the licensing momentum is building, and the AI power infrastructure buildout provides a long runway. Those facts are not in dispute.
The tension is the price. At a recent price near $223.90, Vicor trades more than 228% above GuruFocus’ GF Value estimate, one widely used intrinsic value gauge. Buying here means paying for a second fab, several more licensing deals, and years of royalty growth before a single dollar of it has been reported. That is a lot of future to own at today’s price, especially with insiders using every spike to reduce their exposure. VICR earns a watchlist spot for investors willing to size accordingly. A full position at this valuation demands more margin of safety than the stock currently offers.
