Concerns over side effects of AstraZeneca Plc’s COVID-19 vaccine failed to dent the trading debut of its Korean partner SK Bioscience Co., which more than doubled on Thursday, boosting its market cap to 12.9 trillion won ($11.5 billion).
Following a record amount of bids from retail investors for its $1.33 billion initial public offering, SK Bioscience saw its shares gain by their 160% daily limit to 169,000 won per share from the float price of 65,000 won.
The heavily subscribed IPO by SK Bioscience, the local manufacturer of AstraZeneca’s vaccine, is the largest domestic listing since game developer Netmarble Corp. raised $2.39 billion in 2017. It comes just a week after a hot $4.6 billion New York share sale by e-commerce giant Coupang Inc. drew attention to Korean listings globally.
The strong performance by SK Bioscience makes the vaccine-making unit of family-controlled conglomerate SK Group the 28th-largest stock on the benchmark Kospi, just behind cosmetics group Amorepacific Corp.
Its debut comes as several European Union countries such as Germany and France temporarily suspend the Astra vaccine roll-out on worries about side-effects. The World Health Organization said the vaccine should continue to be administered. The European Medicines Agency is due to provide a definitive assessment on Thursday.
“It is difficult to tell exactly how much negative impact this will have on SK Bioscience,” analyst Douglas Kim said in a note on Smartkarmabefore its trading debut.
South Korea plans to inoculate 12 million people before July, with early batches of the vaccine relying mostly on Astra shots manufactured in SK Bioscience’s factory in the southeastern city of Andong. SK Bioscience also signed a licensing agreement last month with Novavax Inc. to manufacture its Covid-19 vaccine in South Korea.
Korean health authorities said on Wednesday that it had so far found no reports of blood-clotting in the country after AstraZeneca vaccine shots. President Moon Jae-in is set to receive the Astra vaccine next week.
SK Bioscience is among the slew of Korean companies trying to ride on the boom market after the country’s benchmark Kospi soared 30% in 2020 on a flood of retail buying. Drugmakers and health-care stocks were among the biggest winners during the pandemic, though their stock price gains have lost steam in 2021. SK Biopharmaceuticals Co., another biotech arm of SK Group focusing on new drug development, saw its shares jump more than three times from its IPO offer price in 2020. That surge in Kospi has prompted local companies from KakaoBank Corp. to Krafton Inc. to seek a listing of their shares, potentially making 2021 a record year for IPOs in South Korea.
SK Bioscience benefited from retail investors’ hunger for shares. Korean mom-and-pop buyers poured in a record 63.6 trillion won ($56.3 billion) to get their hands on SK Bioscience shares, beating the previous 59 trillion won in retail bids for last year’s $321.5 million IPO by Kakao Games Corp., the gaming unit of South Korea’s leading messaging app, Kakao Corp.
Institutional investors, who made up 55% of the SK Bioscience IPO, also poured into the offering. Bids from institutional investors were oversubscribed by 1,275 times.
SK Bioscience has said it is planning to use the IPO proceeds for research and development, as well as establishing a plant to produce the next-generation pneumococcal vaccine in its pipeline, among other things.
SK Chemicals, the SK Group unit that held 98% of SK Bioscience stock before the IPO now has 68%, having sold 7.65 million share sales during the float.
The deal was arranged by NH Investment & Securities Co., Korea Investment & Securities Co., and Mirae Asset Daewoo Co.
