| Item 3. | Source and Amount of Funds or Other Consideration | |
As described in Item 4 below, on February 19, 2026, ETP Global III Fund L.P. purchased a convertible note with a principal amount of US$5 million using its working capital pursuant to certain Note Purchase Agreement between ETP Global III Fund L.P. and the Issuer dated December 11, 2025. | ||

A convertible note with a principal amount of US$5 million has been issued to the Purchaser on the same date (the "Convertible Note"). The Purchaser has the right to convert such note into the Company's ordinary shares, par value US$0.0001 per share (the "Ordinary Shares") at any time from and including the 91st day after the issuance thereof to and including the maturity date at a conversion price of the volume weighted average closing price of the Company's Ordinary Shares during the five consecutive trading days immediately preceding the date of conversion notice by ETP Global III Fund L.P.

The descriptions of the Convertible Note are qualified in their entirety by reference to the Convertible Note itself, a copy of which is attached hereto as Exhibit B and incorporated hereby by reference in its entirety.
The beneficial ownership reported hereof included Ordinary Shares that the reporting person has the right to acquire within 60 days, through the conversion of such Convertible Note, with an assumed conversion price of US $1, given consideration of the average volume-weighted closing price of the Company's Ordinary Shares of US$0.15 for the last five trading days. | ||
