Analysis · INM · Life Sciences
Mentari Therapeutics has added $200 million to its pre-closing private placement, lifting the total to $490 million alongside the original $290 million. The new capital comes from a syndicate of blue-chip healthcare investors and is priced at a 52.8% premium to the original round — a strong signal of demand. With the proceeds, the combined company's runway now extends into 2029, funding both PACAP-targeted programs through Phase 2a readouts. For InMed shareholders, however, the dilution is stark: they will own just 1.15% of the combined entity, down from earlier estimates. The deal de-risks the merger financing and validates Mentari's pipeline, but leaves legacy InMed holders with a sliver of the upside.
