Although investor sentiment continues to remain low and unlikely to change for the remainder of the year, it seems that fact has fallen on deaf ears of those companies looking to graduate to the public ranks. Already in the first few days of September, five biopharma companies have added themselves to the IPO runway, bringing the number of pending U.S. offerings to 12, according to BioWorld.

HONG KONG – Sinomab Bioscience Ltd., a Hong Kong clinical-stage antibody firm, said its application for a Hong Kong IPO was accepted by the stock exchange, making it the 16th biopharma to submit an application under the new rules of the Hong Kong Exchange (HKEX).

DUBLIN – To no one's great surprise, the underwriters of Genmab A/S's IPO on Nasdaq exercised their overallotment option, the company announced Friday, taking the total gross to $581.8 million. The Copenhagen-based antibody developer priced the offering of about 32.8 million American depositary shares at $17.75 Thursday. The stock (NASDAQ:GMAB) ended the week at $18.10.

Despite the ups and downs of the general markets and a U.S. government shutdown at the beginning of the year that contributed to no biopharma companies graduating to the public ranks in January, the enthusiasm for biopharma IPOs has remained steady since then. In fact, a flurry of IPO listings on U.S. stock exchanges last month helped bring the total of those offerings to 30 at the halfway point in the year. 

Although the public biopharmaceutical sector set a fast pace at the beginning of the year, it has been all downhill since February, with the BioWorld Biopharmaceutical index losing 16% of its value. However, a strong performance in June, with the group gaining 7.6%, helped the sector marginally push into positive territory year-to-date (YTD). At the halfway point of the year, the index is trailing the general market by a wide margin, with the Dow Jones Industrial Average trading up 14% and the Nasdaq Composite index up 20%.
