Earnings Call Summary

The company closed its acquisition of Amicus last week and is integrating two therapies for rare genetic disorders. Q1 revenue of 766 million dollars was below guidance due to order timing from strong Q4 orders, but patient demand remains robust with Voxzogo patient growth up 20 percent year over year and new adolescent label for Palynziq driving physician engagement. Management expects Q2 EPS to be only modestly higher than Q1 due to pre-close acquisition costs and revenue timing weighted to later quarters, but pivotal data readouts for Voxzogo in hypochondroplasia and BMN-401 are expected in Q2.

Guidance BioMarin raised full year revenue guidance to 3.825 to 3.925 billion dollars after closing the Amicus acquisition, which adds Galafold and Pombility to their Enzyme Therapies portfolio. They expect 20 percent revenue growth in 2026 at the midpoint, with about 55 percent of annual revenue coming in the second half of the year due to order timing and eight months of Amicus product sales beginning in May.

Severe negative reset. The report materially damaged the forward outlook and likely forces major downward revisions.
