Item 8.01 Other Events.
As disclosed in a current
report on Form 8-K filed by HH&L Acquisition Co. (“HH&L”) with the U.S. Securities and Exchange Commission
(the “SEC”) on February 9, 2023, shareholders of HH&L approved the Extension Amendment Proposal to amend the second
amended and restated memorandum and articles of HH&L (as amended on February 7, 2023, the “Second MAA”), thereby
providing HH&L the rights to extend the Termination Date (as defined in the definitive proxy statement on Schedule 14A filed by HH&L
on January 17, 2023 with the SEC (the “Definitive Proxy Statement”)) from February 9, 2023 to March 9, 2023, and in
the event that HH&L does not consummate a business combination by March 9, 2023, to further extend the Termination Date for two additional
one-month periods for an aggregate of two months, from March 9, 2023 to May 9, 2023, by resolutions of the Board of Directors (the “Board”)
of HH&L and without approval of shareholders of HH&L (each, an “Extension”).
In February 2023, the Board
of HH&L implemented an Extension, thereby extending the Termination Date to March 9, 2023.
On March 6, 2023, pursuant
to the Second MAA, the Board of HH&L resolved, through unanimous written resolutions, to implement a second Extension to allow additional
time for HH&L to complete its initial business combination and extend the Termination Date to April 9, 2023.
Pursuant to the Extension
Amendment Proposal, on or prior to March 16, 2023, HH&L will deposit into the Trust Account US$380,000, as Contribution for the Additional
Extension Period from March 9, 2023 to April 9, 2023.
