Vicor Corporation (VICR) Q3 2026 earnings review

Vicor's patent royalties tripled, but its new orders slowed

Vicor's patent royalties carried a record quarter while orders for its power modules slowed. Revenue reached $197 million, up 79% from a year ago, and royalties tripled because an AI equipment maker took the first licence to the company's vertical power delivery design. Product shipments rose 16% from last quarter, a smaller step than the royalties, and chief executive Patrizio Vinciarelli said the company bought two sites for new factories.

At a glance
Revenue$197.1M +79% from a year ago
Royalty revenue$66.6M $21.7M a year ago
Backlog$406M +7% from last quarter
Full-year revenue outlookNot updated July floor of over $600M; by our math Q4 needs only $147M

โš–๏ธ Verdict: ๐ŸŸข Bullish

The story got better because licensing is turning into a business with contracted customers rather than a string of lawsuits: a first licence at per-unit rates, and a trade commission investigation that Vinciarelli said is bringing more licence inquiries. Margins on the modules themselves also recovered, by our math, after slipping last quarter. The bad news: new orders added only $26 million to the backlog, against $79 million last quarter, so the demand behind the factory expansion is harder to see.

The question now is how much of this quarter's royalty income repeats. Either the new licence pays Vicor for every unit its customer ships, so royalties stay near a third of revenue, or Vicor booked much of it at signing, as it did with $15 million last quarter, and the line drops back. Next quarter's royalty figure and the revenue note in the quarterly filing will tell.

๐Ÿ‚ Bull Case

๐ŸŸข๐ŸŸข strengthening GROWTH

Patent Royalties Became a Third of Revenue

Vicor earns money two ways. It sells power modules built in its own plant, and it licenses its patents to equipment makers and cloud operators whose systems would otherwise infringe them. This quarter royalties tripled to $66.6 million, 34% of revenue by our math, and for the first time they drove the result.

Chief executive Patrizio Vinciarelli said Vicor "granted our first VPD license to an AI OEM at Stage-2 unit royalty rates". VPD, short for vertical power delivery, is the company's method of feeding current to AI processors. On October 9 the US International Trade Commission opened an investigation into imports Vicor says infringe those patents, which Vinciarelli said is "prompting inquiries about licenses at royalty rates that strongly favor early adopters".

Royalties carry no factory cost, so they lifted gross margin to 68.3% from 58.0% last quarter. They are not free, though: selling and administrative costs rose $11 million from last quarter, partly on "contingency fees to law firms enforcing Vicor IP", the release said. And the line can swing, because last quarter $15 million of royalties came from signing one contract rather than from shipments.

What to watch: the royalty line next quarter and the revenue note in the quarterly filing that splits it. A figure that holds near this quarter's level would show the new licence pays as its customer ships, which is what the licensing case needs.

๐ŸŸข fading MARGIN

Factory Margins Improved Without Counting Royalties

Vicor reports one gross margin for modules and royalties together, so the royalty jump hides what the factory earned. Because the cost line covers products only, we can strip the royalties out: by our math the margin on modules reached 52.2%, against 46.7% last quarter, the highest in the five quarters we can compute.

The cost of making the products fell to 47.8% of product revenue from 53.3% last quarter, so the Andover plant is absorbing its fixed costs better as volume rises. One quarter does not settle it, because finance chief James Schmidt blamed last quarter's slip on an equipment move he did not quantify, and the release says nothing about that charge now.

What to watch: the same calculation next quarter. A product margin that stays above 50% would show the gain came from volume rather than from one favourable mix of orders.

๐ŸŸข strengthening GROWTH

Revenue Beat the Company's Own Plan by a Quarter

In July finance chief James Schmidt told investors to expect revenue nearly 10% above the second quarter, about $158 million by our math. Vicor delivered 25% more than that, a second beat in a row against its own plan and a larger one than the first.

The size of the beat says the plan was cautious, not that demand changed, because management set it assuming no new licence before the trade commission ruled, and a new licence arrived anyway. The same caution now hangs over the full-year floor of over $600 million. After nine months of $453 million, by our math Vicor needs only $147 million in the fourth quarter to reach it, less than it just reported.

What to watch: whether Schmidt states a fourth-quarter figure or a new full-year number. A full-year number well above $600 million would show the July floor was never the plan.

๐ŸŸข strengthening CAPITAL ALLOCATION

Vicor Bought Sites for Two More Factories

Vicor makes its modules in one plant in Andover, Massachusetts, which it calls ChiP Fab-1. Last quarter Vinciarelli said that plant was approaching full use and no second site had been chosen. He now says the company has bought two sites within 30 miles of it, and that three plants would give "a nearly 5X increase in capacity from 3 Fabs".

The purchase answers where the capacity will come from, but not when. The release gives no cost and no opening date, and management said last quarter that a second plant would not contribute before late 2027, so the ceiling on shipments stays in place for several quarters while customers decide whether to wait.

What to watch: capital spending and the commitments note in the quarterly filing. A step up in commitments would show Vicor is spending the money on time.

๐Ÿป Bear Case

๐Ÿ”ด๐Ÿ”ด persistent GROWTH contradicts narrative

New Orders Slowed While Vicor Bought More Factories

Vicor's backlog is the value of orders scheduled to ship within twelve months, and it sets the pace for product revenue. The backlog is still rising, to $406 million, but the amount Vicor adds to it each quarter is shrinking fast, so the stock looks strong while the flow behind it weakens.

  • Added to backlog this quarter: $26 million, by our math
  • Added last quarter: $79 million; the quarter before that: $124 million
  • Orders against shipments: about 1.2 to 1 by our math, after above 2 to 1 in the first quarter and just above 1 in the second, as management reported

Vinciarelli announced the purchase of two more factory sites and said "Capacity expansion is necessary in view of demand and industry trends." But the order flow points the other way: shipments grew faster than in any quarter of the past year, while new orders barely outran them. He also confirmed last quarter that customers were ordering further ahead as lead times stretched, so part of the backlog may be scheduling rather than new demand.

What to watch: the backlog next quarter against product revenue. A backlog that falls while shipments rise would mean customers pulled orders forward into the capacity shortage rather than placed new ones.

๐Ÿ”ด persistent GROWTH

Shipments Grew Less Than the Plan Needed

The July plan rested on hardware, because management had scheduled only $5 million of royalties from its newest licence for this quarter. By our math that left the plan needing $133โ€“140 million of product revenue. Vicor shipped $130.5 million, up 16% from last quarter, the largest step in the past year but still short of the range.

The total still beat the plan by a wide margin because royalties arrived instead, so the licensing line, not the factory, closed the gap. That means the test of whether the backlog converts into shipments at the pace the plan assumed is not yet passed. The 47% rise in product revenue from a year ago says less, because the year-ago quarter was small.

What to watch: product revenue next quarter against the backlog at the start of it. Another sequential rise near this quarter's pace would show the factory can ship as fast as the backlog implies.

๐Ÿ”ด persistent DISCLOSURE

Risks this quarter didn't answer

The release comes with no transcript, no quarterly filing and no outlook, so four standing concerns got no new numbers, and the list below says where each one will next become readable.

  • Customer concentration: the share of revenue and backlog from the largest AI customer; the quarterly filing's customer note will show it.
  • Licence renewals: the two-year agreements begin expiring in 2027, and nothing in the release says how a renewal works or what happens if a licensee declines.
  • Royalty recognition: how much of this quarter's royalty figure Vicor booked at signing rather than earned per unit shipped; the filing's revenue note will show it.
  • Current density: the promise to push second-generation VPD past 5 amps per square millimetre by early next year got no update; the next call should.

Vicor Says Rival Chip-Side Regulators Hit Limits

Vinciarelli again argued against VRs and IVRs, the voltage regulators that sit beside or inside an AI processor and compete with Vicor's modules. He said they "face electrical, mechanical and thermal barriers to escalating AI processor requirements" and that the Open Compute industry group "confirmed the challenges of VRs and IVRs". Vicor showed its second-generation VPD to equipment makers and cloud operators in private sessions, drawing "positive feedback and interest in engaging", but the release names no customer and no order.

๐Ÿ’ฒ Other KPIs

Accounts receivable (26Q3) $122.5 million
โ‡— accelerating

Customers owe Vicor more: receivables rose 55% from June, while revenue rose 38%. Receivables are the money owed for goods and licences already billed. Measured in days of sales, by our math they reached about 57, up from 44 a year ago. The release does not say whether licence payments billed late in the quarter account for the jump.

Free cash flow (26Q3) $53.6 million
โ‡— accelerating

Cash from operations less capital spending rose to $53.6 million from $22.8 million last quarter, the third rise in a row after the first quarter's litigation payment turned it negative. Capital spending reached 8% of revenue, about double the year-ago share, as the Andover plant adds equipment. Cash on hand ended at $513 million.

Treasury stock (26Q3) $165.9 million
โ‡— accelerating

Treasury stock, the cost of Vicor's own shares it holds, rose by $37.8 million from June by our math. The release does not mention repurchases, and the figure can also include shares withheld to cover employees' taxes, so the quarterly filing will show which. Diluted shares still stood 6% above a year ago after stock issuance.

โ“ Key Questions

Does the full-year outlook of over $600 million still stand?

The release contains no outlook. After nine months of $453 million, the July floor needs only $147 million in the fourth quarter, less than Vicor just reported, so it no longer tells investors anything about the next quarter.

How much of this quarter's royalty income recurs each quarter?

Last quarter $15 million was booked at signing. The new VPD licence carries per-unit rates, so the split between unit royalties and signing-day recognition decides whether royalties stay near a third of revenue.

What did the two new sites cost, and when will they ship?

Capital spending is already 8% of revenue. Without a budget and an opening date, nobody can judge how long the capacity ceiling lasts or how much cash the expansion absorbs.

Was the lead AI customer more than 10% of revenue?

Management declined to quantify concentration in each of the last two quarters. The backlog's quality cannot be judged without knowing how much of it one customer holds.

How much of the $11 million rise in SG&A was legal contingency fees?

The release says operating expenses include fees to law firms enforcing Vicor's patents. Accrued expenses rose $14.6 million from June, so the fee rate on royalties matters for the margin the licensing business really earns.
