Filing Released Lang Actions
DISCLOSEABLE TRANSACTION IN RELATION TO THE DISPOSAL OF 20% EQUITY INTEREST IN AN ASSOCIATE
Regulatory Filings Classification · 1% confidence The document is a Hong Kong Stock Exchange announcement under the GEM Listing Rules disclosing a ‘disclosable transaction’ – namely, the sale (disposal) of a 20% equity interest in an associate. It is not a full financial report, management discussion, proxy statement, dividend notice, or other more specific form. It is a regulatory announcement of a share disposal transaction, which does not neatly fit into capital-raising (CAP), share issue (SHA), share purchase (POS), M&A takeover (TAR) or any other specific category. Thus it falls into the general regulatory announcement fallback category: RNS.

NEXT DAY DISCLOSURE RETURN
Transaction in Own Shares Classification · 1% confidence The document is a Next Day Disclosure Return under Hong Kong Listing Rules detailing the repurchase of ordinary shares (treasury shares) by the issuer, including opening and closing balances, repurchase date, price, quantities, and confirmations under Main Board and GEM Rules. This is a direct report of the company buying back its own shares, matching the definition of Transaction in Own Shares (POS), rather than a financing update, board change, or regulatory filing announcement. Thus, it should be classified as POS.
2025-06-16 English
NEXT DAY DISCLOSURE RETURN
Transaction in Own Shares Classification · 1% confidence The document is a Hong Kong Stock Exchange “Next Day Disclosure Return” reporting changes in issued shares and treasury shares, specifically detailing a repurchase of 8,000 shares as treasury shares pursuant to Main Board Rule 10.06(4)(a) / GEM Rule 13.13(1). This falls squarely under “Transaction in Own Shares” (share buyback/repurchase).
2025-06-06 English
NEXT DAY DISCLOSURE RETURN
Transaction in Own Shares Classification · 1% confidence The document is a Next Day Disclosure Return (Form FF305) filed under Hong Kong Stock Exchange rules, detailing changes in issued shares and treasury shares, specifically share repurchases (buybacks) and on-market sales of treasury shares. This is a direct report of the company’s transactions in its own shares. According to the classification definitions, this falls under "Transaction in Own Shares (POS)".
2025-06-04 English
MONTHLY RETURN OF EQUITY ISSUER ON MOVEMENTS IN SECURITIES FOR THE MONTH ENDED 31 MAY 2025
Regulatory Filings Classification · 1% confidence The document is a regulatory ‘Monthly Return for Equity Issuer and Hong Kong Depositary Receipts’ filed under Chapter 19B of the HKEX Listing Rules, detailing movements in authorised share capital, issued shares, treasury shares and repurchases for the month ended 31 May 2025. This is a continuous listing-rule compliance filing to the exchange and does not match the specialized categories for annual reports, earnings releases, board changes, share-issuance notices or buyback notifications alone. It is therefore classified under the fallback “Regulatory Filings” category (RNS).
2025-06-03 English
NEXT DAY DISCLOSURE RETURN
Transaction in Own Shares Classification · 1% confidence The document is a statutory ‘Next Day Disclosure Return’ under Hong Kong Listing Rules detailing changes in issued and treasury shares, specifically reporting on-market share repurchases and changes in issued share capital. This corresponds to a company’s own share transactions (buybacks and treasury sales). It is not an AGM, earnings release, or annual report but a transaction report in own shares. Therefore, the correct classification is POS (Transaction in Own Shares).
