At the bottom of the income statement, Vicor also provided a surprise, reporting net income of $63.3 million, or $1.33 per diluted share, compared to $28.3 million, or $0.63 per diluted share, in Q3 2025. Analysts had anticipated Vicor posting diluted earnings per share of $1.24 for Q3 2026.
It wasn't merely the insight into the company's recent financial performance that investors celebrated, however. Vicor reported a backlog totaling $406 million as of the end of September 2026 -- a 166% increase from the $153 million it had at the end of September 2025.
Is it too late to load up on Vicor stock?
Because it licenses its power system technologies to hyper-scalers, Vicor has emerged as yet another artificial intelligence (AI) stock investment opportunity -- specifically one that provides data center exposure. And while the hype around AI investments has waned recently, Vicor stock is still up about 87% since the start of the year. And with the impressive performance, Vicor's stock has now soared to a rich valuation. Currently, shares are trading at 75.8 times operating cash flow, a premium to its five-year average cash flow multiple of 36.6. At this point, investors should wait for the stock to experience a pullback before they choose to pull the trigger on a Vicor investment.
