BioMarin closes Alesta deal, adding ALE1 oral therapy for hypophosphatasia

Why it may matterVerify against the original reporting
The acquisition adds optionality via an oral HPP asset, potentially re-rating BioMarin's growth optionality; however, near-term upside is limited until Phase 1/2a data and regulatory milestones materialize. Historically, strategic acquisitions with late-stage or clinical-stage assets can lift valuation on pipeline optionality, but are tempered by integration and clinical execution risks.
