PROFIT WARNING

This announcement is made by SIM Technology Group Limited ("Company", together with its subsidiaries, the "Group") pursuant to Rule 13.09(2) of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited ("Listing Rules") and the Inside Information Provisions (as defined in the Listing Rules) under Part XIVA of the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong).

The board ("Board") of directors of the Company ("Directors") wishes to inform the shareholders ("Shareholders") and potential investors of the Company that, based on the preliminary review of the unaudited consolidated management accounts of the Group for the year ended 31 December 2025 ("FY2025") and information currently available to the Company, the Group is expected to record a loss attributable to the owners of the Company in the range of approximately HK$5 million to HK$20 million for FY2025, which was substantially decreased as compared to that for the year ended 31 December 2024 ("FY2024") of approximately HK$95 million.

The Board considers that the significant decrease in loss in FY2025 as compared to that for FY2024 was primarily attributable to the following factors: First, the systematic enhancement of operational awareness among all employees of the Group, implementation of optimized appraisal and incentive mechanisms and effective cost-control measures have resulted in a further reduction in labour cost compared with last year. Second, increased factory utilization has contributed to the realisation of economies of scale. Third, by proactively phasing out projects with negative gross margins and low efficiency, the product structure has been gradually improved. Fourth, the dissolution of several subsidiaries in the People's Republic of

China in 2024 resulted in a one-time exchange loss of approximately HK$30.8 million.

Shareholders should note that the Company is still in the process of (i) finalising the change in fair value of the Group’s financial assets and investment properties; and (ii) performing impairment assessment on certain current and non-current assets of the Group. The aforementioned loss attributable to owners of the Company is subject to adjustment after the finalisation of the fair value valuation and impairment assessment.

The information contained in this announcement is only based on a preliminary assessment by the Board with reference to the unaudited consolidated management accounts of the Group for FY2025 and information currently available to the Company, and is not based on any figures or information which have been audited or reviewed by the Company’s auditors. There may be changes or adjustments following further review of the unaudited management accounts for FY2025 by the Board.

Shareholders and potential investors of the Company are advised to exercise caution when dealing in the securities of the Company.
