Key Dates

Recommendation

Keros Therapeutics has demonstrated a remarkable financial turnaround, moving from a significant net loss to a substantial net income in FY 2025, largely driven by a strategic license agreement. The company maintains a robust cash runway into H1 2028, providing ample liquidity for its operations. Critically, Keros is advancing its lead product candidate, rinvatercept, into Phase 2 trials for two high-need indications (DMD and ALS) with clear timelines. These factors, combined with a strengthened leadership team, suggest strong operational execution and significant potential for future value creation, making it an attractive investment.
