The company anticipates immaterial exposure to U.S. tariffs for China, Mexico, and Canada, expecting limited impact in 2025.

Management Comments

• "We were very pleased with our second quarter performance across all aspects of the business, including strong growth, exciting pipeline progress, and delivery of our business development strategy."
• "In the quarter, global demand for BioMarin's innovative therapies resulted in double-digit year-over-year revenue growth and significant profitability expansion."
• "Today, we are pleased to share early data for BMN 333, a potential new treatment option for children with achondroplasia. BMN 333, our long-acting CNP, achieved our targeted profile in the healthy volunteer study and is now expected to move into the pivotal study in 2026. Our goal is for BMN 333 to demonstrate superiority to VOXZOGO and set a new standard for the treatment of achondroplasia."
• "We were also pleased to have delivered on our business development strategy with the acquisition of Inozyme, which closed on July 1st. The acquisition strengthens our portfolio, adding a late stage enzyme replacement therapy, BMN 401, formerly INZ-701, for the treatment of ENPP1 Deficiency."
• "With the first half of the year now complete, I am pleased with our progress and remain enthusiastic about our potential to deliver for patients, employees and our shareholders through the remainder of 2025 and beyond."

Industry Context

BioMarin operates in the highly specialized and high-growth rare disease biotechnology sector, characterized by significant unmet medical needs and premium pricing for innovative therapies. The strong performance of VOXZOGO and the strategic acquisition of Inozyme, adding BMN 401 for ENPP1 Deficiency, align with the industry trend of focusing on orphan drugs and genetic conditions, which often benefit from accelerated regulatory pathways and strong market exclusivity. The company's emphasis on expanding its achondroplasia franchise with BMN 333 and exploring new indications for VOXZOGO demonstrates a commitment to leadership in this specific therapeutic area. The discontinuation of BMN 390 highlights the inherent R&D risks in drug development, a common challenge across the biotech industry, but the redeployment of resources indicates a strategic approach to portfolio management.

Comparison to Industry Standards

• The reported 16% year-over-year revenue growth and 50% Non-GAAP Diluted EPS growth for Q2 2025 are strong indicators of performance, particularly in the specialized rare disease market where high growth rates are often seen for successful new therapies like VOXZOGO.
• The expansion of GAAP Operating Margin by 16.6 percentage points and Non-GAAP Operating Margin by 8.7 percentage points suggests effective cost management and leverage of sales growth, which is a positive trend compared to many biotech companies that may struggle with profitability during growth phases.
• The acquisition of Inozyme and its lead candidate BMN 401 for ENPP1 Deficiency positions BioMarin in a new rare genetic disorder, similar to how other rare disease specialists like Alexion Pharmaceuticals (now AstraZeneca Rare Disease) or Sarepta Therapeutics expand their portfolios into new indications with high unmet needs.
• The development of BMN 333 as a potential next-generation therapy for achondroplasia, aiming for superiority over VOXZOGO, reflects a strategy of internal competition and innovation, a practice seen in leading pharmaceutical companies that seek to extend their market leadership in key therapeutic areas.
• The discontinuation of BMN 390 due to immunogenicity is a common occurrence in drug development, reflecting the high attrition rate of preclinical and clinical candidates across the pharmaceutical industry. Companies like Pfizer or Novartis regularly prune their pipelines based on early-stage data.

Stakeholder Impact

• Shareholders: Positive impact due to strong financial performance, raised guidance, and promising pipeline developments, potentially leading to increased share value.
• Patients: Positive impact through continued access to existing innovative therapies (VOXZOGO, Enzyme Therapies) and the advancement of new potential treatments for rare genetic conditions (BMN 333, BMN 401, PALYNZIQ expansion).
• Employees: Generally positive, with redeployment of employees from the discontinued BMN 390 program, indicating internal opportunities. Continued investment in business initiatives suggests job stability and growth.
• Customers (Healthcare Providers): Positive, as new treatment options and expanded indications become available, enhancing their ability to treat patients with rare diseases.
• Creditors: Positive, as strong operating cash flow and a healthy cash balance of approximately $1.9 billion indicate robust financial health and ability to meet obligations.

Next Steps

• Finalize accounting for the Inozyme acquisition and include acquired IPR&D charges in Q3 2025 financial results.
• Provide an update on full-year 2025 guidance items, including the impact of acquired IPR&D charges, in the Q3 2025 earnings update.
• Initiate the registration-enabling Phase 2/3 study for BMN 333 in 1H 2026.
• Share initial data for BMN 351 (Duchenne muscular dystrophy) by year-end 2025.
• Begin the Phase 2 study for BMN 349 (AATD-associated liver disease) in 1H 2026.

• Submit applications to expand PALYNZIQ age eligibility (12-17 years) in the U.S. and Europe in 2H 2025.
• Share topline data from VOXZOGO pivotal study in hypochondroplasia in 1H 2026.
• File submissions to global health authorities for VOXZOGO in hypochondroplasia in 2H 2026.
• Continue to advance VOXZOGO's CANOPY clinical program in additional indications (hypochondroplasia, idiopathic short stature, Noonan syndrome, Turner syndrome, SHOX deficiency).
• Progress plans to advance BMN 401 for ENPP1 Deficiency across additional age groups and evaluate for other indications.
• Continue increasing new patient starts for VOXZOGO, execute U.S. expansion initiatives, and ongoing OUS build-out.
