Vicor's royalty revenue jumps to $66.6m on a new patent license

Vicor's royalty revenue rose to $66.6m in the third quarter from $21.7m a year earlier, and the power-module maker's quarterly report, filed with the SEC on Oct. 26, ties the jump to a new license agreement signed during the quarter. Total revenue rose 78.5% to $197.1m.

Royalties now supply 33.8%* of Vicor's revenue, and they do far more for its profits. The company books cost of revenue only against products, so license income goes straight to gross margin. Gross margin rose to 68.3% of revenue from 57.5%, and operating income rose to $72.1m from $20.9m. Diluted earnings were $1.33 a share, against $0.63.

Vicor has not named the licensee. Its results release, furnished to the SEC on Oct. 20, says it granted its first license for vertical power delivery, Vicor's technology for powering AI processors, to an AI equipment maker.

Neither the 10-Q nor the release says how much of the $66.6m covers sales made before the quarter. That gap matters. Vicor's own history shows how quickly royalties can fall back: in the third quarter of 2025 they included a catch-up amount, the company said in February, and in the fourth quarter they dropped to $14.5m. The 10-Q adds that certain licenses are booked as cash arrives, which makes the line lumpier still.

The product business needs no such caveat. Product revenue rose 47.1%* from a year earlier to $130.5m. Within it, Advanced Products, whose sales the 10-Q says are concentrated in the data center and hyperscaler segments, brought in $72.2m* excluding royalties, up 65.0%*. Brick Products, the older converters sold mainly to defense, industrial and transport customers, rose 29.7% to $58.3m. The 10-Q credits improved market demand for both.

Orders support more of the same. Backlog, which Vicor defines as orders scheduled to ship within 12 months, was $406.0m at Sept. 30, up from $379.7m at June 30. Inventory rose 6.2% in the quarter to $110.9m, which the 10-Q says was in anticipation of higher volume to fill that backlog.

Licensing has a cost, but it sits lower down the income statement. Selling, general and administrative expense rose $15.8m from a year earlier to $38.6m, and legal fees made up $13.9m of the increase. The 10-Q attributes the legal-fee increase mainly to licensing agreements and to more legal activity. Legal fees reached $16.1m* in the quarter, equal to 24.2%* of royalty revenue, and the release says operating expenses include contingency fees to the law firms enforcing Vicor's patents.

Not all of the quarter's revenue has reached the bank. Receivables were $122.5m at Sept. 30, 2.02 times* the level at the end of 2025. Operating cash flow for the nine months fell to $80.4m from $123.8m, as receivables rose by $61.8m and Vicor paid SynQor $28.6m in March to satisfy a patent judgment in full. The third quarter alone was stronger: the release puts operating cash flow at $69.7m, against capital spending of $16.1m.

The balance sheet carries no debt and $513.1m of cash, which gives Vicor room for its expansion plans. Its chief executive, Patrizio Vinciarelli, said in the release that the purchase of two more sites within 30 miles of its first fab, in Andover, Mass., will give Vicor three fabs with nearly five times the first fab's capacity. The 10-Q lists $14.0m of capex commitments, mainly for production equipment, and gives no price for either site. Vicor bought back no shares in the quarter, though the board authorized up to $150m of buybacks in August.

The quarter shows two businesses moving at different speeds. The module business is growing on demand that the backlog and inventory build both corroborate. The licensing business produced 33.8%* of revenue in a single quarter on the strength of one new agreement whose terms, timing and licensee are undisclosed. Investors who value Vicor on third-quarter earnings are valuing a royalty stream that has fallen back once before.

The release gives no fourth-quarter outlook, and without one the quarter cannot yet be read as a new run rate.
