Regulatory Filings Classification · 95% confidence The document is a monthly return filing (Form FF301) submitted to the Hong Kong Exchanges and Clearing Limited (HKEX) regarding movements in securities for the month ended 30 April 2026. It details movements in authorized share capital, issued shares, treasury shares, and public float sufficiency confirmation. It is a regulatory compliance report related to share capital and public float requirements under the Exchange Listing Rules. The document is not an annual or interim financial report, earnings release, or management discussion. It is a regulatory filing providing updates on share capital and public float status, which fits the category of Regulatory Filings (RNS). The document length is about 5761 characters, and it contains detailed data rather than just an announcement of a report, so it is not a Report Publication Announcement (RPA).
2026-05-04 English
RESUMPTION GUIDANCE
Regulatory Filings Classification · 95% confidence The document is an announcement from Sunho Biologics, Inc. regarding the resumption guidance issued by the Hong Kong Stock Exchange due to the company's trading suspension. It references the delay in publication of the 2025 Annual Results and outlines conditions for resumption of trading, including conducting investigations, internal control reviews, and publishing outstanding financial results. The document is a regulatory announcement about compliance and trading suspension status rather than the actual annual report or financial results. It is not a full financial report but a compliance and status update related to regulatory requirements and listing rules. Therefore, it fits best under Regulatory Filings (RNS). The document length (6081 characters) and content confirm it is a detailed regulatory announcement, not a report or presentation.

Report Publication Announcement Classification · 90% confidence The document is a regulatory announcement notifying shareholders of a further delay in publishing the Company’s 2025 Annual Results and despatch of its 2025 Annual Report, as well as continued suspension of trading. It does not contain the actual annual results or report itself but rather informs of the timing and publication status of those reports. Therefore, it falls under “Report Publication Announcement” (RPA).
2026-04-27 English
FURTHER SUPPLEMENTAL ANNOUNCEMENT IN RELATION TO THE DELAY IN PUBLICATION OF THE ANNUAL RESULTS ANNOUNCEMENT FOR THE YEAR ENDED DECEMBER 31, 2025 AND CONTINUED SUSPENSION OF TRADING
Regulatory Filings Classification · 95% confidence The document is an announcement from Sunho Biologics, Inc. regarding the delay in publication of its 2025 Annual Results and the continued suspension of trading of its shares.

It is a regulatory announcement related to compliance with listing rules and disclosure obligations. The document length is 6563 characters, which is relatively short and consistent with an announcement rather than a full report. Therefore, this document fits best under Regulatory Filings (RNS) as it is a regulatory announcement about the delay and suspension, not the annual report itself.

Monthly Return of Equity Issuer on Movements in Securities for the Month Ended 31 March 2026
Regulatory Filings Classification · 87% confidence The document is a routine monthly return (Form FF301) filed with the Hong Kong Stock Exchange under its Listing Rules, detailing movements in share capital, issued shares, and public float confirmations. It is not a full financial report (10-K or interim/quarterly report), nor is it an investor presentation, dividend notice, M&A, or management change. It also does not announce a specific new share issue or buyback; rather it is a compliance filing under exchange regulations. Therefore, it falls into the general “Regulatory Filings” category (RNS).
2026-04-09 English
SUSPENSION OF TRADING
Regulatory Filings Classification · 80% confidence The document is an official announcement published on the Hong Kong Stock Exchange regarding the suspension of trading in the company’s shares. It does not present financial results, management analysis, or governance rules, nor is it a voting result, delisting notice, or specific report. It is a miscellaneous regulatory announcement filing that does not neatly fit other categories. Therefore it should be classified as a general Regulatory Filing (RNS).
