SELLAS Life Sciences: The Ownership Structure Has Changed Before The Defining Catalyst

SELLAS Life Sciences enters its pivotal REGAL readout with a transformed shareholder base, stronger balance sheet, and a new supply structure. Institutional ownership doubled to 36.34%, with average allocation rising, reflecting both new and existing holders increasing stakes ahead of the binary event. Passive and index-linked funds now dominate SLS's register, while multi-strategy and quant funds have exited, reducing volatility-driven trading around the catalyst. SLS holds an estimated $138.3M cash, providing multi-year runway and flexibility post-readout, with its Greater China license intact and short interest declining. REGAL remains the defining catalyst, with the final 80th event approaching after an extended event-driven timeline and prior IDMC continuation recommendation, reflecting longer-than-expected survival follow-up.

SELLAS now has a different shareholder base, a stronger balance sheet, and a new supply structure as it approaches a key binary event.
