Publication Date: Nov -01

📋 Highlights
  • $1.13 Billion Revenue: Q3 total product net sales reached $1.13 billion, driven by $1 billion in VYVGART sales.
  • 3 Phase III Therapies: Three first-in-class molecules (efgartigimod, empasiprubart, ARGX-119) in Phase III, targeting autoimmune and neurological diseases.
  • Operating Expenses: Q3 expenses rose 5% to $805 million, with R&D up 9% ($28M) and SG&A up 4% ($11M).
  • MG Market Leadership: VYVGART is #1 prescribed biologic in MG, with 100% YoY growth and 60,000-patient opportunity.
  • 5 Phase III Readouts: Five registrational trials expected in 2026, including CMS for ARGX-119 and seronegative gMG expansion for efgartigimod.

Commercial Performance

The commercial performance was strong, with consistent delivery of new patient growth for 15 quarters while executing on the strategy to unlock the full 60,000 patient opportunity in Myasthenia Gravis (MG). VYVGART remains the #1 prescribed and fastest-growing biologic in MG, with a strong safety and efficacy profile driving earlier prescribing decisions. The prefilled syringe was a major driver of growth this quarter, continuing the trend seen since the subcutaneous version was launched. The IV formulation continues to be an important contributor to the business.

Pipeline Progress

Argenx is making significant progress in its pipeline, with three first-in-class molecules in Phase III development: efgartigimod, empasiprubart, and ARGX-119. The company is excited about the potential expansion of its label to include seronegative gMG patients following positive top-line results. The unmet need in this area is significant, especially for triple seronegative patients who experience diagnostic challenges and currently have no approved therapies.

Valuation Metrics

With a P/E Ratio of 53.7 and an EV/EBITDA of 115.95, the market is pricing in significant growth expectations. Analysts estimate next year's revenue growth at 34.0%, indicating a strong outlook for the company. The ROE (%) is 18.96, indicating a relatively high return on equity. The Net Debt / EBITDA ratio is -4.93, indicating a healthy debt position.

Guidance and Outlook

The operating expenses for the rest of the year are guided between $2.6 billion and $2.7 billion, with a focus on investing in growth. The company is excited about the size of the opportunity in Graves' disease, with a large prevalence of the disease and a clear unmet need. The trial design for Graves' disease will be presented soon, and the company is not commenting on the potential disease modification.
