Two guidance increases, both credited to royalties from the same licensing deal, have added roughly $29 million to the company's implied revenue floor. The open question is whether the money repeats.
Vicor has rewritten its third-quarter outlook twice in less than two weeks, and both times the reason was the same: royalties from a single license on its Vertical Power Delivery technology.
After Wednesday's close, the power-components maker said it now expects third-quarter revenue to grow more than 30% from the second quarter, up from "more than 20%." On , it had raised the same guidance from "nearly 10%." Each time, Vicor pointed to royalties from its first non-exclusive VPD license, granted to a company it described only as a leading AI original equipment maker.
Shares rose 11.73% to $322.84 in premarket trading Thursday, from a $288.94 close. The move added about $1.56 billion to the company's market value.
Putting dollars on the percentages
Vicor guides only in percentages, but the math against its second-quarter revenue of $143.4 million is straightforward. "Nearly 10%" growth implied a third quarter of about $157.7 million. More than 20% implied at least $172.0 million. More than 30% implies at least $186.4 million. The two raises together lifted the implied floor by roughly $28.7 million, and the company attributes the entire increase to one licensee.
Because royalties generally carry little manufacturing cost, additional licensing revenue can have a substantial effect on operating profit. The ultimate contribution will depend on the agreement's terms and other expenses.
The case that this is an engine
Royalties were already a major business before the VPD deal, accounting for $30.4 million, or about 21%, of second-quarter revenue. Chief Executive Patrizio Vinciarelli has said four leading OEMs and hyperscalers now hold licenses to Vicor's power technology, and that because the first VPD patent was only recently asserted, it is "still possible to secure a license at an early stage of escalation with a low royalty rate." The structure of the new license lets the licensee buy VPD modules from other suppliers while paying Vicor, tying royalties to industry volume rather than Vicor's own factory output. Backlog stood at $380 million at the end of June, up 145% from a year earlier.
The case that this is a lump
Both raises cite the same license, and Vicor has not disclosed the royalty amount, the term or whether any of the payment covers past shipments. That last detail decides everything. A back-royalty would inflate one quarter and set up a difficult comparison. The company's history offers a caution: its second quarter of 2025 included a one-time $45 million patent-litigation settlement.
Valuation leaves little room for disappointment. At Wednesday's close the stock traded at about 93 times trailing earnings, and even after Thursday's jump it sits below its 52-week high of $382.65.
What to watch
Vicor reports third-quarter results on . The size of the royalty line, and any indication of how much of it recurs in the fourth quarter, will determine whether two guidance raises marked the start of a new revenue stream or a single unusually large check.
