POSITIVE PROFIT ALERT

This announcement is made by Twintek Investment Holdings Limited (the "Company", together with its subsidiaries, the "Group") pursuant to Rule 13.09 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules") and the Inside Information Provisions (as defined in the Listing Rules) under Part XIVA of the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).

The board of directors of the Company (the "Board") wishes to inform the shareholders and potential investors of the Company that, based on the information currently available to the Board, and the preliminary review of the unaudited consolidated management accounts of the Group for the year ended 31 March 2021 (the "Year"), the Company is expected to record a consolidated net profit in the range of HK$8.0 million to HK$13.0 million for the Year, as compared to the consolidated net loss of approximately HK$23.8 million for the corresponding year in 2020. The expected turnaround from consolidated net loss to consolidated net profit is mainly attributable to, among other factors: (1) the resumption of certain projects which have been temporarily suspended under the COVID-19 pandemic; and (2) the resumption of a project which has fallen behind schedule due to a change in main contractors in 2018.

The information contained in this announcement is only based on a preliminary assessment of the latest information available to the Board, including the latest unaudited consolidated management accounts of the Group for the Year, which have neither been reviewed by the audit committee of the Company nor reviewed or audited by the Company's auditors. The Group's financial result for the Year will only be ascertained after all the relevant results and accounting treatments are finalised. The actual results of the Group for the Year, which are expected to be announced in late June 2021, may differ from the information contained in this announcement.
