All listed companies in Bursa Malaysia (formerly known as Kuala Lumpur Stock Exchange or KLSE) are required to announce their results quarterly. You can find these quarterly reports at the company announcements section of Bursa Malaysia's web site. Click on the "Announcements" at the left panel, choose either current for recent announcements or historical for old announcements. Remember to sort the list by company.
At the very same page you may find annual reports or audited financial statements. Look at the left panel to search for the words "Annual Audited Accts" or "Annual Reports".
For company database, e.g. profile, directors, shareholders, financial data since 1997, etc., you may sign in to KLSE-RIIAM Information System. There is a wealth of free information on all the counters listed in Bursa Malaysia.
