NautaDutilh advised the underwriters in the USD 862.5 (including over-allotment option) million capital raise of argenx. This was the 4th time that argenx raised its capital since its Nasdaq IPO in May 2017 and also the 5th time that the NautaDutilh Amsterdam and Brussels teams were involved. This transaction was not only the largest capital raise for argenx to date, but it also marks the largest ECM transaction of a European biotech in history on any exchange.
Only one day before launch of the offering, on May 26, argenx publicly announced that its lead medicine efgartigimod met the primary endpoint for a Phase III trial in myasthenia gravis. This resulted in a share price increase of over 30% in one day on both Euronext Brussels and Nasdaq and an upsize of the original size of the transaction due to a strong demand.
