Argenx posts Q3 2026 sales surge and announces Forte Biosciences acquisition

Argenx reported third‑quarter 2026 product net sales of about $1.7 billion, up roughly 54 % year‑over‑year, driven by VYVGART. Net income rose to $506 million and earnings per share reached $7.80. The company completed a $2.2 billion acquisition of Forte Biosciences and said it expects combined R&D and SG&A expenses of about $4 billion in 2026. It also announced that Phase 3 data for empasiprubart are slated for December 2026 and that FB102 will move into a Phase 3 trial in celiac disease.

The revenue jump and acquisition expand Argenx’s product portfolio, but higher R&D and integration costs compress operating margin, which investors must weigh. Future Phase 3 readouts could drive further upside if the trials are positive, as the company highlighted in its update.
