FINANCIAL EFFECT OF THE DISPOSAL AND USE OF PROCEEDS

On 3 March 2026, it was announced that the Group had decided to divest the Target Company, which had been classified as a discontinued operation of the Group in 2025, and its business was classified as assets held for sale on the expectation of a sale of the business. Upon Closing, the Target Company will cease to be a subsidiary of the Company with its financial results no longer being consolidated into the consolidated financial statements of the Group.

Shareholders should note that the actual financial effect of the Disposal on the Group will depend on, among other things, the financial position of the Target Company at Closing and the final purchase price adjustments, and is further subject to a final audit.

Based on (i) the total Purchase Price of US$120 million (approximately HK$940 million); (ii) the adjusted unaudited net asset value of the Target Company (exclusive of intercompany balances) as at 31 March 2026 of approximately HK$833 million; and (iii) the estimated adjustments on working capital, cash and indebtedness at the Closing, the Group is expected to recognise an estimated net gain of approximately HK$11 million upon the Closing.

The actual gain on disposal of the Target Company will be subject to the review and final audit by the auditor of the Company and will depend on, amongst others, (i) the carrying value of the Target Company at Closing, (ii) the agreed adjustments on closing working capital, closing cash and closing indebtedness at the Closing, as well as (iii) the actual transaction costs incurred.

The proceeds are intended for disciplined capital allocation in line with the Group’s payout policy and growth priorities, primarily to bolster core business operations.

REASONS FOR AND BENEFITS OF THE DISPOSAL

The Target Company is a separate major line of the Group’s semiconductor solutions business. For the strategic fit of the Group’s businesses, the Group had decided to divest the Target Company from the semiconductor solutions segment through sale, which will help to sharpen the Group’s focus on the back-end packaging business. The Group believes that the Target Company is better positioned for long-term success under a new owner that can provide continued investment and operational synergies. Moreover, the Disposal enables the Group to realise value from its investment in the Target Company’s business and to reallocate resources in line with the Group’s strategic priorities.

Having considered the above factors, the Directors consider that the terms and conditions of the Disposal (including the Purchase Price) is fair and reasonable and in the interests of the Company and its shareholders as a whole.
