Vicor Nearly Doubles Q3 Growth Guidance as AI Chipmakers Pay Up for Power Patents
Vicor raised its fiscal Q3 sequential revenue growth forecast to more than 20% from nearly 10%, driven by royalties from a new patent license deal for its Vertical Power Delivery technology.

Dow Jones Newswires (full wire text read via TradingView, Sept. 22, 2026) reports the guidance raise, the royalty driver, the four licensees and the import-ban rationale, the $254.48 Tuesday close (+14%), the 366% year-to-date gain, the Needham estimate changes, and the May Q2 raise. Vicor's company release (GlobeNewswire, Sept. 21) was read in full and informed the draft, but its host is not on Production's refetch-approved host list, so it is documented in the frozen evidence rather than the cited inventory; the same applies to valuation and insider-activity sources. All growth figures are sequential quarter-over-quarter, not year-over-year.
Reported Tuesday, September 22, 2026; guidance announced Monday, September 21.
Vicor Corporation nearly doubled its revenue-growth guidance for the fiscal third quarter, saying royalties from a newly licensed patent portfolio will push sequential revenue growth past 20%. Shares rose 14% to $254.48 on Tuesday and have gained 366% this year, according to Dow Jones Market Data.
Late Monday, Vicor told investors the third quarter is shaping up to be much bigger than planned. The power-electronics maker lifted its sequential revenue growth forecast to more than 20%, from the nearly 10% it had expected, saying the driver is royalties from a new patent license deal for its Vertical Power Delivery technology — money from its patent portfolio, not from selling more hardware.
The key numbers: Q3 sequential revenue growth guidance — more than 20%, up from nearly 10% · royalty driver — a new patent license deal for Vicor's artificial-intelligence-power technology, its Vertical Power Delivery architecture for AI chips · four licensed companies so far, a mix of hyperscalers and equipment makers, unnamed · market reaction — shares up 14% Tuesday to $254.48, and up 366% this year, per Dow Jones Market Data · Needham — Buy rating, $320 price target; Q3 revenue estimate raised to $172 million, adjusted EPS to $1.18.
Vicor disclosed the raise late Monday, Sept. 21. The forecast it replaced called for sequential growth of nearly 10%. The new growth comes from royalty fees from a new patent license deal for its artificial-intelligence-power technology, according to Dow Jones Newswires. The technology is Vertical Power Delivery, or VPD — Vicor's patented technology, which the wire calls its core architecture for powering high-performance artificial-intelligence chips.
Chief Executive Patrizio Vinciarelli did not disclose the company's specific clients, but said a total of four major companies — a mix of hyperscalers and original equipment manufacturers — have now secured licenses for Vicor's patented power technology, known as Vertical Power Delivery. His account of why they signed: the clients approached Vicor after realizing that using unlicensed power delivery components put their AI computing systems at risk of import bans from the U.S. International Trade Commission and patent infringement litigation, per Dow Jones Newswires.
Investors moved fast. Shares rose 14% to close at $254.48 on Tuesday, extending an extraordinary run: Vicor is up 366% this year, per Dow Jones Market Data.
Needham analyst Bolton called the new agreement a strong operational success and raised his fiscal 2026 targets on Vicor: he now expects third-quarter revenue of $172 million, up from $158 million, and adjusted earnings of $1.18 a share, up from 89 cents. Needham maintained its Buy rating and its $320 price target.
This is not the first time royalties have moved the guidance. In May, management raised its second-quarter revenue guidance to $142 million from $126 million, citing higher product revenue and additional royalties from an undisclosed new license. The repetition matters: licensing is starting to look like a recurring lever for Vicor rather than a one-time windfall — though the company has not disclosed the royalty rate or how much of the revised outlook comes from the new agreement. What to watch now is whether more hyperscalers and suppliers sign licenses, and whether the third-quarter numbers, when they land, show royalties becoming a durable line item rather than a quarterly surprise.
Vicor in plain English
Sequential growth compares one quarter to the one right before it. Vicor is saying its third-quarter revenue will be more than 20% higher than the second quarter's — up from its earlier expectation of about 10% growth. A royalty is a fee one company pays another for the right to use its patented technology. Vicor owns the patents on a way of delivering power to AI chips, called Vertical Power Delivery. When a hyperscaler or equipment maker pays Vicor to use it, Vicor gets high-margin income without building anything new. The twist in the story: Vicor says some buyers came to the table after realizing that using unlicensed power components put their AI computing systems at risk of import bans from the U.S. International Trade Commission. Signing a license is insurance against getting locked out of the market. The open question for beginners: Vicor has not said what royalty rate it charges or how much of the new forecast comes from the license. Those details arrive with the actual quarterly results.
Vicor for experienced readers
Two guidance raises in two quarters, both citing royalties. In May it was second-quarter revenue to $142 million from $126 million on higher product revenue plus royalties from an undisclosed new license; now it is third-quarter sequential growth to more than 20% on the new Vertical Power Delivery license. The pattern to watch is whether licensing becomes a recurring revenue line or stays a series of one-off boosts. The enforcement posture is the negotiation tool. By pointing to AI computing systems at risk of import bans from the U.S. International Trade Commission, Vicor is pricing the license against the alternative: litigation risk and supply disruption. If more hyperscalers and suppliers sign, VPD licensing becomes a durable royalty stream; if they call the bluff, the royalty story stalls. The open question is scale. Four licensees are disclosed; the royalty rate and the split between royalty income and product revenue are not. The third-quarter actuals will show how much of the more-than-20% sequential growth the new license really delivered.
Not yet known
The release gives no royalty rate and no split of the revised outlook between royalties and product revenue. The identities of the four licensees are unknown, as is whether more hyperscalers and suppliers will sign licenses. The actual third-quarter numbers arrive with Vicor's next earnings report.
