Vicor Corporation stock gains 2.65 percent on higher guidance

Vicor Corporation stock (VICR) was trading at USD 275.45 on Nasdaq on September 23, 2026 at 2:05 p.m. ET, up 2.65 percent from the previous close. The move follows a sharp guidance increase for the third quarter, with revenue growth now expected to exceed 20 percent sequentially.

Guidance rises on royalties

As Yahoo Finance reported on September 22, 2026, Vicor linked the revised outlook to royalty income from Vertical Power Delivery licensing agreements. The company had previously guided to sequential growth of nearly 10 percent, making the new outlook a materially higher threshold for Q3 execution.

The licensing model adds recurring payments alongside direct sales of power modules. That matters because the updated outlook is tied to technology rights and royalties, rather than only to unit volumes. MarketBeat said the license is non-exclusive and involves an AI-systems manufacturer.

Q2 revenue grows 49.3 percent

Vicor's latest reported quarter ended June 30, 2026. According to MetaTrader, Q2 revenue reached USD 143.4 million versus USD 96.0 million in Q2 2025, a year-over-year increase of 49.3 percent. Diluted earnings per share rose to USD 1.04 from USD 0.91, while gross margin fell to 58.0 percent from 65.3 percent.

The figures show a clear split in the earnings profile. Revenue and earnings expanded, but the margin comparison was weaker because the prior-year quarter included a USD 45.0 million patent litigation settlement recorded as revenue. Advanced Products revenue grew 55.5 percent year over year, supporting Vicor's exposure to AI and data-center power demand.

Stock remains below yearly high

Vicor's market capitalization stood at USD 12,487,232,015 on September 23, 2026. The stock's 52-week range was USD 47.56 to USD 382.65, placing the current price 28.0 percent below the yearly high.

Needham reaffirmed a Buy rating and set a USD 320 price target on September 22, 2026, according to MarketBeat. That target sits USD 44.55 above the intraday price, leaving the analyst view dependent on the durability of royalty income and the conversion of AI demand into reported revenue.
