How did ACIU's Q4 2024 earnings surprise impact investor sentiment?

AC Immune SA's (ACIU) Q4 2024 earnings report likely had a mixed impact on investor sentiment, given the company's strategic advances and financial highlights juxtaposed against the negative aspects of a significant earnings miss and a substantial earnings decline year-over-year.

1. **Positive Aspects**:
- **Takeda Partnership**: The announcement of a $100 million upfront payment and potential milestone payments of up to $2.1 billion for the ACI-24.060 immunotherapy partnership with Takeda likely bolstered investor confidence in AC Immune's commercial potential.
- **Clinical Trial Progress**: Positive interim safety data from the ABATE Phase 1b/2 trial for ACI-24.060 in Down syndrome patients, along with encouraging interim data from the ACI-7104.056 trial for Parkinson’s disease, may have contributed to a positive sentiment around the company's clinical pipeline.
- **Financial Strength**: AC Immune's substantial increase in contract revenues to CHF 27.3 million and a cash position of CHF 165.5 million, projected to fund operations through early 2027, may have alleviated concerns about the company's financial health.
2. **Negative Aspects**:
- **Earnings Miss**: AC Immune reported a net loss of CHF 50.9 million for the quarter, which may have disappointed investors, especially considering the consensus estimate was not disclosed. However, the company beat expectations by reporting a smaller loss of ($0.06) per share compared to the consensus estimate of ($0.07).
- **Revenue Shortfall**: The company's revenue fell short of expectations, with reported revenues of $16.71 million for the quarter, compared to analyst estimates of $16.36 million.
- **Year-Over-Year Earnings Decline**: AC Immune's net loss of CHF 50.9 million for Q4 2024 represents a significant increase in losses compared to the previous year, which may have raised concerns about the company's profitability trajectory.

In conclusion, while the Takeda partnership and clinical trial progress may have initially lifted investor sentiment, the earnings miss and revenue shortfall, coupled with a substantial year-over-year earnings decline, likely tempered optimism. Investors will need to weigh these factors against the potential long-term benefits of AC Immune's strategic moves and assess the company's ability to execute on its clinical and commercial plans.
