SK IE Tech IPO draws record-high demand; brokerage servers down briefly

SK IE Technology Co. (SKIET), the battery materials subsidiary of SK Innovation Co., has set a new record for initial public offering demand, briefly paralyzing computer servers and operations at some of the brokerages handling the share sale.

The South Korean electric vehicle battery separator maker has attracted a total of 80.9 trillion won ($73 billion) in deposits from retail investors during the two-day public subscription, official data showed on Apr. 29.

That represents the highest-ever amount deposited from individual investors for an IPO on a Seoul bourse to get shares of SKIET, beating the previous record set just last month by SK Bioscience Co., which pulled in 63.62 trillion won in public subscription.

SKIET’s shares were oversubscribed by 288 times, attracting 4.74 million subscription accounts, around 12% of all active stock accounts owned by individual investors in Korea. About 5% of short-term funds in the financial market has been mobilized to buy the shares of SKIET, also posting a record amount.

Financial industry officials said some small investors won’t be able to secure a single SKIET share due to the overwhelming demand.


Mirae Asset Securities and JPMorgan are managing the IPO with five other co-underwriters – Korea Investment & Securities, Credit Suisse, SK Securities, Samsung Securities and NH Investment & Securities.

According to the IPO managers, so many individual investors rushed to secure SKIET’s shares online that some of the computer servers at securities companies briefly went down and paralyzed work at the brokerages’ branches.

“It looks like all the Korean people are betting on SKIET as if to win the lotto. The IPO fever in Korea won’t easily go away any time soon,” said a brokerage official.

During the bookbuilding with institutional investors last week, SKIET’s IPO price was set at 105,000 won apiece, the top end of the proposed price band, drawing strong interest from large investors, including the National Pension Service (NPS) and BlackRock Inc., the world’s largest asset manager.

The bookbuilding itself was 1,883 times oversubscribed, also posting an all-time high ratio.

Following its successful bookbuilding and public subscription, investors are now paying close attention to how the share price will move once SK IE Technology goes public on May 11.

Market watchers say if SKIET debuts on the Kospi market with its opening price double the offering price and reaches the daily upper limit of 30%, then it could touch 273,000 won, taking the company’s total market capitalization to close to 19.5 trillion won, similar to its parent SK Innovation.

The company's employees and executives are allowed to subscribe to a total of 4.27 million shares as part of the employee stock ownership scheme — thus, on average, each person can hold around 2.06 billion won worth of shares. If the stock opens at double the offering price and hits the daily limit, an employee would see capital gains of 3.3 billion won theoretically.


The underwriting fee, set at 0.8% of the IPO value, will be shared by the lead managers and co-underwriters.

Industry officials said they will be able to receive a combined 17.9 billion won in underwriting fee due to the successful subscription from investors.

SKIET, which makes lithium-ion battery separators (LiBS), plans to float 21.39 million shares, or 30% of its total outstanding shares, on the main bourse through the IPO.

With the set IPO price, SK will likely raise 2.3 trillion won ($2.1 billion) from the share sale

About 63.2% of the institutional investors, including the NPS, have agreed to a lock-up clause, promising not to sell the stock post-IPO for at least three months. For SKIET employees, the lock-up period is one year.

SK Innovation and SKIET plan to use the proceeds from the IPO to expand their EV battery business.

SKIET has said it will build two additional battery separator plants in Poland to meet the rising demand for electric car batteries. The project, valued at around 1.2 trillion won, marks SKIET’s single largest investment.

SKIET was the first South Korean company to develop lithium-ion battery separators in 2004, and the first in the world to develop the sequential stretching process technology in 2007.
