ASX-listed companies are required to follow continuous disclosure obligations under the ASX Listing Rules. Each company must promptly release any information that may have a material effect on its stock price. This includes financial results, changes in leadership, major contracts, mergers, acquisitions, or any significant operational developments. Companies must submit periodic reports such as annual and half-yearly financial statements, quarterly activity updates (for some sectors), and disclose any changes to capital structure. These disclosures are made through the ASX Market Announcements Platform to ensure transparent and timely information for all market participants.
