If a listed company faces accumulated losses of 50% or more of its capital, the company is required to be moved from a first category listing to a second category of listing. This measure is designed to protect investors by ensuring that only financially stable companies remain in the primary listing category, which is subject to stricter regulatory oversight and higher investor expectations. The second category listing provides a lower level of visibility, which reflects the increased financial risks associated with such companies. This helps mitigate the potential impact on other market participants.
