EXPLANATORY NOTE

Reference is made to the Current Report on Form 6-K furnished by Fangdd Network Group Ltd. (the “Company”) with the U.S. Securities and Exchange Commission on October 24, 2025 regarding, among other things, the entry into a convertible note purchase agreement with an investor (the “Note Purchase Agreement”) and a share subscription agreement with ZX International Ltd , a company incorporated in British Virgin Islands and controlled by Mr. Xi Zeng, the chairman of the board of directors and chief executive officer of the Company (the “Share Subscription Agreement”).

On December 5, 2025, the Company received a conversion notice from the investor (the “Noteholder”), the holder of the convertible promissory note in a principal amount of US$34,320,000 (the “Note”). The Note was issued to the Noteholder on October 24, 2025 by the Company pursuant to the Note Purchase Agreement to satisfy the Company’s payment obligations for the acquisition of certain assets from the Noteholder.

Pursuant to the terms of the Note and the conversion notice, the Noteholder has elected to convert the outstanding balance of the Note into an aggregate of 32,971,466 Class A ordinary shares of the Company (the “Conversion Shares”) at a conversion price of US$1.0409 per share. In accordance with the instructions from the Noteholder and the terms of the Note, the Conversion Shares were issued to certain permitted designees of the Noteholder (the “Permitted Designees”). After the issuance of the Conversion Shares, no amount of the Note will remain outstanding and the Note will be cancelled.

Following the conversion of the Note and pursuant to the Share Subscription Agreement, the Company has issued 12,731 Class C ordinary shares of the Company, at a purchase price of US$1.81 per share, to ZX International Ltd.

The conversion of the Note and issuance of Class C ordinary shares described above did not result in a change in control of the Company. Immediately after the conversion of the Note and issuance of Class C ordinary shares, the Company’s total number of ordinary shares outstanding is 38,548,413, comprising of 38,529,284 Class A ordinary shares, 5,450 Class B ordinary shares and 13,679 Class C ordinary shares.

The issuance of the Conversion Shares to the Permitted Designees upon conversion of the Note and the issuance of Class C ordinary shares are exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”) pursuant to Section 4(2) of the Securities Act regarding transactions not involving a public offering and is made in reliance on, and in compliance with, Regulation S under the Securities Act.
