Q3 Revenue Beat Not Enough to Change Cognex's Wait Rating

What happened

Cognex reported Q3 revenue of $313 million, up 19% year over year, with four of five end markets delivering double-digit constant currency growth. This follows a strong Q1 and comes after the stock gained 87% over the past twelve months. The prior DeepValue report set a WAIT rating, a base case value of $62, and a bull case of $76, contingent on proof of AI-driven margin expansion. While the revenue growth exceeds the base case's low-teens assumption, the article lacks details on gross margin, EBITDA margin, or OneVision adoption, leaving the AI thesis unconfirmed. Consequently, the positive revenue print alone is insufficient to upgrade the rating given the stock's rich valuation at 73.5x P/E and 48.5x EV/EBITDA.

Implication

The Q3 revenue growth of 19% supports the bull scenario's high-teens growth, but investors should demand evidence of gross margin above 72%, EBITDA margin above 31%, and explicit AI-related revenue contribution before paying up further. The stock likely trades above $63 given the strong print, but without margin confirmation, the risk-reward remains skewed to the downside relative to the $52 attractive entry. The DeepValue report's base case of $62 is now challenged on the upside, but the bull case of $76 is not yet validated. Maintain a WAIT and look for the next earnings release to confirm margin and AI traction. Consider adding only on a pullback toward $52 or on clear evidence of sustained margin improvement.

Thesis delta

The Q3 revenue print of $313M (+19% y/y) with broad-based growth strengthens the bull scenario but does not yet validate the AI-led margin expansion needed to justify the current premium. The WAIT rating remains appropriate until margin and AI adoption evidence emerges.
