Price vs Fundamentals
Why The Stock Is Moving
Note: The most recent financial data is over 3 months old. Metrics shown may not reflect the latest reporting period.
What changed
The stock fell 38.77% over the last year. Revenue declined 46.21% over the trailing twelve months. Operating margin moved from -3,204.41% to -5,199.84%. Free cash flow declined 0.11% over the trailing twelve months.
What the market seems to be pricing
The market appears to be responding to weaker operating momentum rather than only rerating the stock.
What would invalidate this read
Operating margin stands at -5,199.84%. Revenue declined 46.21% — this read reverses if that trend stabilizes. Free cash flow fell 0.11% — a return toward positive territory would undermine the deterioration thesis. If margins and cash flow stabilize while the stock stays depressed, the gap shifts from fundamental damage toward pure multiple compression.
Company profile
Quantum-Si incorporated operates within the life sciences sector, focusing on the creation of an advanced platform for individual molecule detection.
