Mirum Pharmaceuticals posts strong Q3 sales, raises full‑year guidance and secures FDA approval for ATEBRIOZ

Mirum Pharmaceuticals reported third‑quarter 2026 net product sales of $185.7 million, a 40% year‑over‑year increase driven by LIVMARLI and bile‑acid medicines. The company received U.S. FDA approval and launched ATEBRIOZ for fibrodysplasia ossificans progressiva and announced positive Phase 3 results for LIVMARLI, ATEBRIOZ and brelovitug. It lifted its full‑year net product‑sales outlook to $715 million‑$720 million and plans several regulatory submissions in 2027.

The higher guidance raises revenue expectations for the next twelve months, which could improve cash flow forecasts and reduce the need for additional financing. The FDA approval adds a new marketed product, expanding Mirum’s revenue base.
