Historical Context
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Nov 26 | Investor conferences | Neutral | +0.9% | Announced December fireside chats and investor meetings with webcast access. |
| Nov 14 | Earnings update | Negative | +1.7% | Q3 loss, going-concern doubt, restructuring, added debt and ATM usage. |
| Nov 12 | Conference participation | Neutral | -6.0% | Planned Jefferies and Piper Sandler investor conference presentations and webcasts. |
| Nov 07 | Preclinical data | Positive | +7.0% | Promising pre-clinical data for IO112 and IO170 and 2026 IND plan for IO112. |
| Oct 20 | Phase 3 results | Positive | +25.2% | Phase 3 Cylembio plus KEYTRUDA data showing improved PFS but missed significance. |
Recent history shows stronger positive reactions to clinical data updates, while earnings and financing disclosures with going-concern language drew more mixed or divergent reactions.
Over the last few months, IO Biotech has combined major clinical updates with financing and restructuring actions. Phase 3 melanoma data reported on Oct 20, 2025 and earlier clinical disclosures were followed by notable positive price moves. By contrast, the Nov 14, 2025 Q3 results highlighted operating losses, going-concern risk, new debt, and workforce reductions. The current conference-participation announcement on Nov 26, 2025 fits a pattern of frequent investor-relations activity following these clinical and financial developments.
