Arrowhead Pharmaceuticals Reports $194.3 Million Net Loss, Acquires Priority Review Voucher for $215 Million

Arrowhead Pharmaceuticals reported a net loss of $194.3 million, or $1.36 per share, for the fiscal 2026 third quarter ended June 30, 2026, while revenue rose to approximately $75 million from $28 million in the prior year quarter. The company highlighted positive Phase III results from its SHASTA-3 and SHASTA-4 studies, which met all primary and secondary endpoints with median triglyceride reductions of 79% and 81%, and a 78% reduction in acute pancreatitis events in the broad SHTG population. Commercial revenue from Redemplo reached approximately $2.4 million, more than double the prior quarter, and the company expanded regulatory approvals to five geographies including the EU, Australia, Canada, China, and the U.S. Operating expenses increased to approximately $245 million, driven by a $36 million rise in R&D to $198 million and a $16 million increase in SG&A to $47 million. The acquisition of a priority review voucher for $215 million represents a significant cash outlay, with payment expected in the fiscal fourth quarter following HSR clearance, aimed at potentially accelerating FDA review of the SNDA for SHTG. Arrowhead ended the quarter with approximately $1.6 billion in cash and investments and 141.1 million common shares outstanding.
