THE SHARE CONSOLIDATION PROPOSAL

General

The Board of Directors believes that it is in the best interest of the Company and the shareholders, and is hereby soliciting shareholder approval, to effect a share consolidation of the Company’s authorized issued and unissued shares, at a ratio of 25-for-1, to take effect upon shareholder approval.

The Share Consolidation must be passed by an ordinary resolution which requires the affirmative vote of a simple majority of the votes cast by such shareholders as, being entitled to do so, vote in person or, where proxies are allowed, by proxy or, in the case of corporations, by their duly authorized representative, at the Meeting. If the Company’s shareholders approve this proposal, the Board of Directors will have authority to implement the Share Consolidation at any time after the approval of the Share Consolidation.

The Share Consolidation will be implemented simultaneously for all authorized, issued, and outstanding shares. The Share Consolidation will affect all shareholders uniformly and will have no effect on the proportionate holdings of any individual shareholder, with the exception of adjustments related to the treatment of fractional shares (see below under the subheading “Fractional Shares”).

Purpose of the Share Consolidation

The Company’s Class A ordinary shares are currently listed on Nasdaq under the symbol “JDZG.” Among other requirements, the listing maintenance standards established by Nasdaq require the Class A ordinary shares to have a minimum closing bid price of at least $1.00 per share. Pursuant to the Nasdaq Marketplace Rule 5550(a)(2) (the “Minimum Bid Requirement”), if the closing bid price of the Class A ordinary shares is not equal to or greater than $1.00 for 30 consecutive business days, Nasdaq will send a deficiency notice to the Company.

In addition, Nasdaq now imposes stricter conditions on companies that use a share consolidation to regain compliance with the $1.00 Minimum Bid Requirement. Under the Rule 5810(c)(3)(A)(iv), if the Company’s Class A ordinary shares fail to meet the Minimum Bid Requirement at any time following a reverse stock split effected within the prior twelve months, the Company will not be eligible for the standard cure period and Nasdaq’s Listing Qualifications Department will issue a Staff Delisting Determination with respect to its security.

On December 20, 2024, the Company received a letter from Nasdaq (the “Notice”), notifying the Company that based upon the closing bid price of its securities for the last 30 consecutive business days preceding the Notice, the Company was not in compliance with the Minimum Bid Requirement. On May 23, 2025, at the Company’s annual general meeting, the Company approved a share consolidation to cure the deficiency. Accordingly, on July 18, 2025, the Company received a letter from Nasdaq, notifying that the Company had maintained compliance with the listing rule and is allowed to maintain its listing on Nasdaq.

Because the Company effected a share consolidation on May 23, 2025, pursuant to the Rule 5810(c)(3)(A)(iv), if a second non-compliance with the Minimum Bid Requirement occurs prior to May 23, 2026, the Company will be issued a delisting notice and will not be eligible for the standard cure period. To ensure the Company’s compliance with the Minimum Bid Requirement, the Board of Directors determined that it was in the best interest of the Company and its shareholders to solicit the approval of the Shareholders for the Share Consolidation.

In the event the Class A ordinary shares were to be no longer eligible for continued listing on Nasdaq, the Company could be forced to seek to be traded on the OTC Bulletin Board or in the “pink sheets.” These alternative markets are generally considered to be less efficient than, and not as broad as, Nasdaq, and therefore less desirable. Accordingly, the Board of Directors believes delisting of the Class A ordinary shares would likely have a negative impact on the liquidity and market price of the Class A ordinary shares and may increase the spread between the “bid” and “ask” prices quoted by market makers.

The Board of Directors has considered the potential harm to the Company of a delisting from Nasdaq and believes that delisting could, among other things, adversely affect (i) the trading price of the Class A ordinary shares and (ii) the liquidity and marketability of the Class A ordinary shares. This could reduce the ability of holders of the Class A ordinary shares to purchase or sell Class A ordinary shares as quickly and as inexpensively as they have done historically.

Delisting could also adversely affect the Company’s relationships with customers, who may perceive the Company’s business less favorably, which would have a detrimental effect on the Company’s relationships with these entities.

Furthermore, if the Class A ordinary shares were to be no longer listed on Nasdaq, it may reduce the Company’s access to capital and cause the Company to have less flexibility in responding to its capital requirements. Certain institutional investors may also be less interested or prohibited from investing in the Class A ordinary shares, which may cause the market price of the Class A ordinary shares to decline.

Registration and Trading of the Company’s Class A Ordinary Shares

The Share Consolidation will not affect the registration of the Company’s Class A ordinary shares or the Company’s obligation to publicly file financial and other information with the U.S. Securities and Exchange Commission. When the Share Consolidation is implemented, the Company’s Class A ordinary shares will begin trading on a post-consolidation basis on the effective date that the Company announces such implementation by press release. In connection with the Share Consolidation, the CUSIP number of the Company’s Class A ordinary shares (which is an identifier used by participants in the securities industry to identify the Company’s Class A ordinary shares) will change.

Fractional Shares

No fractional shares will be issued in connection with the Share Consolidation. Instead, record holders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the Share Consolidation ratio will automatically be entitled to receive an additional fraction of one share of the relevant class to round up to the next whole share. For those beneficial holders who hold shares through a brokerage firm, the Company intends to round up fractional shares at the participant level. Cash will not be paid for fractional shares.

Authorized Shares

At the time the Share Consolidation is effective, the Company’s authorized shares will be consolidated at the same ratio meaning there will be a reduction in the number of the authorized shares in the Company by a factor of 25 (as set out above under the subheading “General”).

Street Name Holders of Class A Ordinary Shares

The Company intends for the Share Consolidation to treat shareholders holding Class A ordinary shares in street name through a nominee (such as a bank or broker) in the same manner as shareholders whose shares are registered in their names. Nominees will be instructed to effect the Share Consolidation for their beneficial holders. However, nominees may have different procedures. Accordingly, shareholders holding Class A ordinary shares in street name should contact their nominees.

Share Certificates

Mandatory surrender of certificates is not required by the Company’s shareholders. The Company’s transfer agent will adjust the record books of the Company to reflect the Share Consolidation as of the effective date. New certificates will not be mailed to shareholders.

RESOLUTION TO BE VOTED UPON

The full text of the resolution to be proposed is as follows:

RESOLVED, BY ORDINARY RESOLUTION, that every 25 issued and unissued Class A Ordinary Share of a par value of US$0.0001 each in the Company's share capital, every 25 issued and unissued Class B Ordinary Share of a par value of US$0.0001 each in the Company's share capital, and every 25 issued and unissued preference share of a par value of US$0.0001 each in the Company’s share capital, be consolidated into one Class A ordinary share of a par value of US$0.0025 each, one Class B ordinary share of a par value of US$0.0025 each, and one preference share of a par value of US$0.0025 each, respectively (each a “Consolidated Share”), and each such Consolidated Share shall rank pari passu in all respects with each other and have the rights and privileges and be subject to the restrictions as contained in the amended and restated memorandum and articles of association of the Company (the “Share Consolidation”), so that immediately following the Share Consolidation, the authorized share capital of the Company shall be changed:
