About BIOSYSEN annual reports
Where can I download BIOSYSEN (01355) annual reports?
Every year in the table above links straight to the PDF on HKEXnews, the Hong Kong Stock Exchange's official filing system. Both English and Chinese editions are available. 13 annual reports are indexed, covering 2013 to 2026.
Do Hong Kong listed companies publish quarterly reports?
No. Main Board issuers are only required to publish an interim report (half-year) and an annual report. Quarterly financial reporting is not mandatory, so Hong Kong filings arrive twice a year rather than four times. This page holds 14 interim reports for BIOSYSEN.
What is the difference between an annual report and a results announcement?
A results announcement (final or interim) is the condensed financial summary a company releases shortly after the period ends — usually a few dozen pages. The annual report follows months later and contains the audited financial statements, the directors' report and corporate governance disclosures. Read the announcement for the numbers first, the annual report for the full picture.
