SELLAS Life Sciences Group (SLS) drew fresh attention after announcing that its pivotal Phase 3 REGAL trial in acute myeloid leukemia hit the pre-set 80th event, which triggered the final overall survival analysis.
Against that backdrop, SELLAS Life Sciences Group has seen a sharp pullback in recent weeks, with the share price down 28.2% over 30 days and 28.9% over 90 days. Yet its year-to-date share price return of 92.4% and a one-year total shareholder return of more than 4x signal momentum that has built over a longer horizon as investors react to REGAL and SLS009 milestones.

Most Popular Narrative: 74% Undervalued
SELLAS Life Sciences Group closed at $8.37, while the analyst consensus Narrative on Simply Wall St anchors fair value at $32.50 using a 7.5% discount rate. That gap rests on aggressive assumptions about how the REGAL and SLS009 programs convert into revenue and earnings over the next few years.
The main dependency is that upcoming Phase 3 and Phase 2 readouts for galinpepimut-S and SLS009 support continued development and help justify ongoing collaborations and financing.
The current valuation, including a market capitalization that reached over US$1.5b by mid 2026 and a company that remains unprofitable, indicates that expectations for success in key trials and for projected revenue and earnings growth are already heavily reflected in the share price.
