Vicor rises after quarterly report showing stronger revenue and margins

What happened

Vicor (VICR) rose 7.1% on October 20, 2026, after third-quarter results showed product and royalty revenue of $197 million and higher profitability tied to demand for artificial-intelligence infrastructure. The company reported the quarter’s product and royalty revenue was $197 million and said management is pursuing capacity expansion, including securing two new sites, to meet AI-related and other market demand, according to GlobeNewsWire and Seeking Alpha.

How big was the move

The stock closed at $204.14, and the day’s rise was 7.1%, trading at 1.8 times its 20-day average in volume. Over the last five sessions the stock fell 23.6%, while the S&P 500 over five sessions fell 1.2% and the Technology sector median on the day rose 1.2%. Compared with its sector, the move was 5.8 percentage points better than the sector median. The session’s change was 1.1 times a typical daily move for this stock, and the company has a market sensitivity described as beta of 2.53, meaning the stock tends to move more than the market.

Earnings were released at this session, so the results were the direct cause of the move. The report showed quarterly earnings of $1.33 per share against $1.32 expected, 0.8% above estimates, part of a six-quarter streak of beating consensus. That sequence of surprises, together with strong product and royalty revenue, helps explain the outsized intraday reaction despite the recent five-session weakness.

The technical picture

The stock was 23.2% below its 20-day moving average, 10.9% below its 50-day moving average and 9.3% below its 200-day moving average. The 50-day average is above the 200-day average, a sign of an established uptrend, while the Relative Strength Index (14 days) was 38, a neutral reading between 30 and 70. The stock is 46.7% below the 52-week high. Over one month the stock fell 8.8% and over three months it fell 6.1%, but over one year it rose 255.5% and is 239.7 percentage points ahead of the S&P 500 over that period.

Volatility was 98% annualized over 60 days, higher than 83% of its own readings over five years, underscoring the stock’s tendency for wide swings. That elevated volatility, combined with a beta of 2.53, means price moves can be large when earnings or other material news land.

Fundamentals and valuation

For the four quarters through September 30, 2026, revenue was $560.7 million, which grew 27.0% from a year earlier and versus growth of 11.7% one quarter earlier. Diluted earnings per share for that period were $3.82, and earnings per share growth from a year earlier rose 109.2%. Gross margin widened to 60.6% from 56.7% a year earlier, and operating margin improved to 24.9% from 17.1%. Return on invested capital was 10.5%, while share count over one year increased by 6.0%.

The company’s market value stood at $8.83 billion. The stock trades at 53.4 times trailing earnings and 51.9 times expected earnings. Its price to trailing earnings is lower than 76% of its own readings over the past five years; the five-year median was 76.8 times earnings. Those multiples reflect high expected growth and strong profitability but also embed substantial optimism about future expansion and demand sustainability.

PromtFinance scores paint a mixed picture: Growth was strong at 88 and Quality was Exceptional at 95, while Revisions were Exceptional at 98, signalling improving analyst estimates. Stability was very weak at 21, reflecting the stock’s elevated volatility and recent swings. Value scored 45 (Neutral) and Momentum was 59 (Neutral). Together, the scores underline rapid underlying growth and high margins, while also flagging larger price variability for investors.

Earnings and analyst expectations

Vicor’s last report on October 20, 2026, showed quarterly earnings of $1.33 per share against $1.32 expected, 0.8% above estimates, and the company has delivered six consecutive quarters beating estimates. The average surprise over the last four reports was 60.9% above estimates. The typical two-day reaction after recent reports was that the stock rose 2.4%. The next report is expected on February 18, 2027.

Analyst coverage includes seven analysts, with a consensus rating of Buy and 86% of those ratings at Buy or Strong Buy. The consensus price target is $347.50, which is 70.2% above the closing price. That gap reflects high expectations for continued revenue and margin expansion tied to product sales and royalties, and for the company’s ability to scale capacity to meet demand.
