Analysis · CMMB · Life Sciences
Just days after Chemomab Therapeutics announced a definitive reverse merger with Scipher Medicine, HBM Healthcare Investments—a Cayman-based venture capital firm—disclosed a 12.5% beneficial ownership stake, comprising 18.2 million ordinary shares via ADSs and 62.8 million ordinary shares underlying pre-funded warrants. The combined company will redomicile in the U.S. and list on Nasdaq under ticker 'SCIP'. In a move that significantly de-risks the merger vote, HBM has entered into a shareholder support agreement, committing to vote its entire stake in favor of the transaction and against any competing proposals. To fulfill these voting obligations, HBM raised its beneficial ownership blocker on the pre-funded warrants from 4.99% to 19.99%, effective September 7, 2026, and intends to exercise the warrants on a cashless basis. This alignment of a major institutional investor signals strong confidence in the deal, which is expected to close in Q4 2026. Existing Chemomab shareholders will receive contingent value rights tied to legacy asset nebokitug milestones, offering potential upside. The disclosure solidifies the merger's path forward and underscores institutional support at a critical juncture.
