Vicor Q2 Beat Confirms AI Tailwinds, But Valuation Leaves Little Room for Error

What happened

Vicor reported a strong Q2, with revenue of $143.4M (up 27% sequentially) and royalties reaching $30.4M, driven by AI power demand and a new OEM license. Backlog hit $380M and gross margin improved to 58%, highlighting operational leverage. Management emphasized plans for a second ChiP fab to address capacity constraints that currently cap shipment growth. However, the stock already trades at 71x earnings, pricing in sustained high royalties and seamless capacity expansion. The next 6-9 months must demonstrate royalty durability (above $25M/quarter) and a committed Fab 2 timeline to justify the multiple.

Implication

If Q3 royalties remain above $25M and Fab 2 gets a dated plan, reassess for potential buy; otherwise, risk of multiple compression if expectations slip.

Thesis delta

The Q2 beat strengthens the bull case on AI momentum and licensing but does not shift the WAIT rating—valuation already reflects these positives. The key unresolved issues are royalty sustainability and capacity execution, which will determine whether the stock can grow into its multiple.
