MONTHLY RETURN OF EQUITY ISSUER ON MOVEMENTS IN SECURITIES FOR THE MONTH ENDED 31 JANUARY 2026
Share Issue/Capital Change Classification · 1% confidence The document is a 'Monthly Return for Equity Issuer' filed with the Hong Kong Exchanges and Clearing Limited. This is a standard regulatory filing required by the HKEX for listed companies to report movements in securities, share capital, and public float status on a monthly basis. It does not fit into specific categories like 'Share Issue' (as it reports no movement) or 'Annual Report', but rather serves as a recurring regulatory disclosure of share capital status.

VOLUNTARY ANNOUNCEMENT - APPROVAL OF OUR APPLICATION FOR TRIVALENT SUBUNIT INFLUENZA VACCINE BY THE NMPA
Regulatory Filings Classification · 1% confidence The document is a voluntary announcement issued by Ab&B Bio-Tech regarding the NMPA approval of their trivalent subunit influenza vaccine. It does not fit into specific financial reporting categories like 10-K, IR, or ER, nor is it a report publication announcement (RPA) as it contains the substantive news itself rather than just announcing the availability of a report. As it is a general corporate regulatory announcement regarding business operations and product approval, it falls under the fallback category of Regulatory Filings (RNS).
