Reverse Share Split and Share Consolidation

On September 3, 2025, at an extraordinary general meeting of shareholders of Yueda Digital Holding (the “Company”), the shareholders approved an ordinary resolution authorizing the Company’s board of directors (the “Board”) to effect a reverse share split and share consolidation (the “Reverse Share Split and Share Consolidation”) of the Company’s authorized and issued share capital, at a ratio of up to one-for-one hundred (1:100), but in any case at a ratio of not less than one-for-five (1:5), the exact ratio of which shall be determined by the Board in its sole discretion, at a date to be determined by the Board, with the exact ratios to be set at a whole number within this range.

On November 4, 2025, the Board approved a Reverse Share Split and Share Consolidation at a ratio of one-for-one hundred (1:100) and determined that the effective time of the Reverse Share Split and Share Consolidation would be November 14, 2025. Trading of the Company’s Class A ordinary shares on a split-adjusted basis on The Nasdaq Capital Market is expected to begin at the open of business on November 14, 2025 (the “Effective Date”). Following the Reverse Share Split and Share Consolidation, each shareholder’s percentage ownership interest in the Company and the proportional voting power will remain unchanged except for adjustments resulting from the treatment of fractional shares, which will be rounded up as disclosed in the Company’s press release. As a result of the Reverse Share Split and Share Consolidation, the authorized share capital of the Company shall be altered from US$40,000,000 divided into (i) 900,000,000 Class A ordinary shares of a par value of US$0.04 each and (ii) 100,000,000 Class B ordinary shares of a par value of US$0.04 each, to US$40,000,000 divided into (i) 9,000,000 Class A ordinary shares of a par value of US$4.00 each and (ii) 1,000,000 Class B ordinary shares of a par value of US$4.00 each.

The Company’s Class A ordinary shares will continue to trade under the symbol “YDKG”, but will trade under a new CUSIP number G0137L110 effective as of the Effective Date.

A copy of the Company’s press release announcing the details of the Reverse Share Split and Share Consolidation is furnished as Exhibit 99.1 to this Report on Form 6-K.

Yueda Digital Holding Announces One-for-OneHundred Reverse Share Split and Share Consolidation

New York, NY, Nov. 10, 2025 /PRNewswire/ -- Yueda Digital Holding (Nasdaq: YDKG) (“Yueda” or the “Company”), a Web3 and digital-economy company with a focus on the long-term accumulation of mainstream cryptocurrencies, today announced that on November 4, 2025, the Company’s board of directors approved a one-for-one hundred (1:100) consolidation (the “Reverse Share Split and Share Consolidation”) of the Company’s authorized and issued shares, to be effective for trading purposes at the open of business on November 14, 2025.

The objective of the Reverse Share Split and Share Consolidation is to enable the Company to regain compliance with Nasdaq Marketplace Rule 5550(a)(2), which pertains to the minimum bid price requirement, and maintain its listing on the Nasdaq Capital Market.

Beginning with the opening of trading on November 14, 2025, the Company’s Class A ordinary shares will trade on the Nasdaq Capital Market on a split-adjusted basis, under the same symbol “YDKG” but under a new CUSIP number, G0137L110.

As a result of the Reverse Share Split and Share Consolidation, each 100 issued and outstanding Class A ordinary shares of a par value of US$0.04 each will automatically combine and convert to one issued and outstanding Class A ordinary share of a par value of US$4.00 each. Similarly, each 100 issued and outstanding Class B ordinary shares of a par value of US$0.04 each will be consolidated into one issued and outstanding Class B ordinary share of a par value of US$4.00 each. The Reverse Share Split and Share Consolidation will affect all shareholders uniformly and will not alter any shareholder’s percentage ownership interest in the Company, except for minimal changes that may result from the treatment of fractional shares. No action is required by shareholders holding their shares through a brokerage account.

No fractional shares will be issued to any shareholders in connection with the Reverse Share Split and Share Consolidation, and any fractional shares that would have resulted from the Reverse Share Split and Share Consolidation will be rounded up to the nearest whole number. Each shareholder that would otherwise be so entitled to a fraction of a share shall instead, as a result of the Reverse Share Split and Share Consolidation, be entitled to receive a whole share.

At the time the Reverse Share Split and Share Consolidation is effective, the Company’s authorized share capital will be changed from US$40,000,000 divided into (i) 900,000,000 Class A ordinary shares of a par value of US$0.04 each and (ii) 100,000,000 Class B ordinary shares of a par value of US$ 0.04 each, to US$40,000,000 divided into (i) 9,000,000 Class A ordinary shares of a par value of US$4.00 each and (ii) 1,000,000 Class B ordinary shares of a par value of US$4.00 each. The Company’s total issued and outstanding Class A ordinary shares will be changed from 554,220,134 Class A ordinary shares with a par value of US$0.04 per share to approximately 5,542,224 Class A ordinary shares with a par value of US$4.00 per share.
