EXPLANATORY NOTE

Convertible Note Transaction with Certain Investors

On May 16, 2025, the Company entered into Convertible Note Purchase Agreements (“CNPA”) with certain investors (the “Investors”). Pursuant to the CNPAs, the Company will issue to the Investors convertible notes in one or more tranches with an aggregate original principal amount of $80,000,000 (the “Notes”). On May 20, 2025, the Company issued in the aggregate $20,000,000 of Notes to the Investors.

Each of the Notes, once effective, will have a term of 360 days. The Notes carry an aggregate original issue discount of $6,400,000. The Company will bear the costs and other transaction expenses incurred in connection with the purchase and sale of the Notes.

Each Investor has the right to elect to convert all or a portion of the outstanding balance under each of the Note into Class A ordinary shares of US$0.2 each in the capital of the Company (the “ordinary shares”) pursuant to the following formula: conversion shares equals amount being converted divided by the conversion price, which is calculated as (A) the lowest market closing price of the Company’s ordinary shares in the 90 trading days preceding the date of conversion request (B) multiplied by 70% and (C) rounded down to the nearest 2 decimal places. The conversion is subject to adjustment in the event of a share subdivision, share dividend, recapitalization, or similar transaction.

Ownership Limitation: The Company may at it option decline to effect any conversion of the outstanding balance under each of the Note to the extent that after giving effect to such conversion would cause the Investors (on an individual basis) to beneficially own a number of shares exceeding 9.99% of the number of ordinary shares outstanding on such date

Upon occurrence of an Event of Default (as defined in the Note), the interest rate shall accrue on the outstanding balance at the rate equal to 10% per annum. In the event of a default, Investors will continue to have the right to make conversions until such time the outstanding balance is paid in full.

The Registrant will use the net proceeds from the offering of the Note for working capital and general corporate purposes.

The foregoing descriptions of the Purchase Agreements and the Notes are summaries of the material terms of such agreements, do not purport to be complete and are qualified in their entirety by reference to the Purchase Agreements, and the Notes, which are attached hereto as Exhibits 99.1, and 99.2. The prospectus supplement relating to the Offering is filed on the SEC’s web site at http://www.sec.gov.
