Mirae Asset Securities, which took part in the underwriting group for SpaceX's initial public offering, saw its entire allocation of IPO shares cut during the final allocation process. Mirae Asset Securities refunded in full the subscription deposits paid by domestic investors.

On June 13, the financial investment industry said SpaceX had planned to allocate 2,314,815 shares to Mirae Asset Securities out of 555,555,555 Class A common shares being sold in the IPO.

But lead manager Goldman Sachs did not allocate sellable shares to some underwriters, including Mirae Asset Securities, in the final allocation process, it said. It was attributed to a reallocation of shares as demand from institutional investors surged after the Nasdaq listing.

Underwriting amounts listed in U.S. Securities and Exchange Commission filings refer to the underwriting ratio based on participation in the underwriting group. They may differ from the final allocation of shares that can be sold to investors.

Mirae Asset Securities accepted subscriptions for SpaceX IPO shares from domestic individual and corporate professional investors and institutional investors through June 10. The offering was conducted in two rounds, with a total target amount of $500 million. Investor interest was strong enough that it closed within 1 to 2 minutes after sales began.

But the subscriptions did not lead to an actual allocation because no final sellable shares were allocated. Mirae Asset Securities processed full refunds of subscription deposits paid by investors early on June 13.

A Mirae Asset Securities official said, "The sellable shares actually allocated to each underwriter are determined at the lead manager's final discretion, and we are sorry to have caused inconvenience to customers because the allocated shares disappeared in this process."

The official added, "We are sorry for the inconvenience caused to customers who waited for the results of this IPO subscription," and said, "We will continue to do our best to protect investors and provide stable services."

SpaceX listed on Nasdaq on June 12 local time. The offering price was $135 per share, and the first-day closing price rose 19.34 percent from the offering price to $161.11. SpaceX was reported to have raised $75 billion, about 114 trillion won, through the IPO.
