Chengdu, China, March 18, 2026 (GLOBE NEWSWIRE) -- JIADE LIMITED (Nasdaq: JDZG) ("JIADE" or the "Company"), a provider of one-stop comprehensive education support services for adult education institutions through its subsidiaries in the People's Republic of China, today announced that it will effect a reverse stock split of its ordinary shares on a 1-for-25 basis (the "Reverse Stock Split").

The Reverse Stock Split has been approved by the Company's shareholders and the Company's board of directors, and is being effectuated primarily to regain compliance with Nasdaq Marketplace Rule 5550(a)(2) relating to the maintenance of the minimum bid price per share of the Company's Class A ordinary shares.

Any fractional shares that would have otherwise resulted from the Reverse Stock Split will be rounded up to the next whole number and no fractional shares will be issued. The Reverse Stock Split affects all shareholders uniformly and will not alter any shareholder's percentage interest in the Company's outstanding ordinary shares, except for adjustments that may result from the rounding up of fractional shares.

Upon the effectiveness of the Reverse Stock Split, every twenty-five shares of the Company's issued and outstanding Class A ordinary shares as of the effective date will automatically be combined into one Class A ordinary share, every twenty-five shares of the Company's issued and outstanding Class B ordinary shares as of the effective date will automatically be combined into one Class B ordinary share, and every twenty-five shares of the Company's preference shares will automatically be combined into one preference share. Such adjustments will reduce the total number of (i) outstanding Class A ordinary shares of the Company from approximately 34.3 million to approximately 1.4 million, (ii) outstanding Class B ordinary shares of the Company from approximately 1.1 million to approximately 42,082, and (iii) preference shares of the Company from approximately 30 million to approximately 1.2 million.
