With the latest results on the table, the next step is to see how these earnings and margin trends line up with the most widely held narratives around Cognex and where those stories might need updating.

TTM earnings and margins pull ahead of revenue

• Over the last twelve months, revenue came in at US$1.0b while net income reached US$142.5 million, giving a 13.6% net margin versus 12.8% a year earlier and 20.8% earnings growth over that period.
• Supporters of the bullish view highlight Cognex's push into AI vision and platforms like OneVision. This recent 20.8% earnings growth with a higher net margin adds some weight to that view, although it still sits against a five year annualised earnings decline of 23.7%, which shows how much catch up is baked into that optimistic story.
  • The bullish narrative leans on structurally higher margins over time. However, the data in hand shows a move to 13.6% today from 12.8% a year ago, which is progress but far from the mid 20% margin levels bullish scenarios often reference.
  • Revenue of about US$1.0b in the trailing period provides a base for that thesis, but the long term earnings decline figure reminds you that execution over multiple years has been uneven compared with the rapid earnings ramp that bullish investors talk about.

Supporters who think this margin and earnings uptick already points toward the bullish scenario may want to see how that case is built out in full before leaning on it too heavily. 🐂 Cognex Bull Case

Premium P/E of 77x sets a high bar

• Cognex trades at a trailing P/E of 77x, well above the peer average of 49.2x and the US Electronic industry at 27.7x, while the DCF fair value in the data is US$30.73 against a current share price of US$65.91.
• Skeptics focus on this valuation gap, and the numbers here support that caution because earnings grew 20.8% over the last year off a five year annualised decline of 23.7%, which is a much choppier history than the premium multiple and the 68.00 analyst target price imply.
  • The DCF fair value of US$30.73 is less than half of the share price, suggesting the current 77x P/E already assumes ongoing earnings growth well beyond the recent 20.8% trailing increase.
  • With the stock also described as more volatile than the US market over the past three months, the combination of rich multiples and recent price swings is exactly the kind of setup bearish investors point to when arguing the downside case.

Skeptical investors who see a stretched multiple and a large gap to DCF fair value may want to walk through how the bear case connects those concerns to future earnings paths. 🐻 Cognex Bear Case

Quarterly EPS swings highlight cyclical exposure

• Basic EPS has moved from US$0.14 in Q1 2025 to US$0.31 in Q1 2026, but the path in between ranged from US$0.11 in Q3 2025 to US$0.24 in Q2 2025 and US$0.20 in Q4 2025, showing a wide band of quarterly outcomes even as trailing twelve month EPS reached US$0.85.
• Analysts' consensus narrative talks about a broader move into AI powered vision and more diverse end markets to smooth cyclical swings. The current pattern fits that story only partly, because the trailing figures show better margins and higher EPS on a twelve month view while the quarter to quarter EPS volatility still reflects exposure to cyclical sectors like electronics and automotive that the narrative flags as ongoing risks.
  • The trailing revenue line moving from US$914.5 million to US$1.0b across the last six rolling quarters gives some scale to that transition, but it does not remove the shorter term lumpiness in quarterly EPS that comes with those end markets.
  • That mix of improving trailing margins and choppy single quarter EPS is exactly what the consensus view is trying to balance when it talks about both opportunities in new verticals and pressure from commoditisation and competitive pricing.
