The lawsuit formalizes known legal risks and could pressure ERAS shares further as the lead plaintiff deadline approaches. Monitor for Erasca's response (e.g., 8-K filing) and any settlement discussions. The recent $550M offering provides cash for R&D but also dilutes existing holders, compounding negative sentiment.
