SINGAPORE, July 8 (Reuters) – SK Hynix will close bookbuilding for its $28 billion offering of American depositary receipts (ADRs) on Wednesday U.S. time, as orders have already covered its books multiple times, ​said a source with knowledge of the matter.

Underwriters of the ‌South Korean chipmaker’s offering, one of the world’s largest new share sales ever, told investors books would close at 4 p.m., U.S. Eastern Time, and pricing guidance would come after the Thursday close of the South Korean market, with allocations finalised later Thursday ‌U.S. ​time, the source said.

SK Hynix had said in ⁠filings it would set the ⁠final price of the ADR offering on Thursday and start trading on the Nasdaq on July 10.

U.S.-based investors came in with chunky orders starting in the range of $200 million, the source said, adding larger orders ​exceeded $1 billion.

SK Hynix declined to comment.

It said on Monday that Baillie Gifford Overseas Limited, investment funds managed by Coatue Management and Situational Awareness ⁠Partners have each separately indicated interest in ⁠purchasing up to a combined $7 billion of its U.S. ADRs.

IFR ​first reported on Tuesday SK Hynix’s ADR offering was multiple times covered.

The buoyant ​response from investors reflects strong demand still for a piece ‌of one of the world’s largest chipmakers, even as global tech stocks dived amid renewed conflict in the Middle East.

SK Hynix shares lost as much as 3.59% on Wednesday.

The company launched the ADR sale on Monday, offering ⁠17.79 million new shares, making it one of the world’s most valuable tech firms.

The deal is expected to be the second-biggest share sale after a record $85.7 ⁠billion initial public offering ‌by SpaceX last month, surpassing Saudi Aramco’s $25.6 billion IPO ⁠in 2019 and Alibaba’s similar-sized offering in 2014.

SK Hynix ​is a ‌key supplier of high-bandwidth memory chips used in ​AI systems by ⁠customers such as Nvidia and Alphabet Inc’s Google.

Ten ADRs will represent one common share and a Monday filing gave a reference price of 242,500 won per ADR, based on SK Hynix’s July 3 closing price in Seoul.
