Wison Engineering Services Co. Ltd. (Wison Engrg) filed its monthly return for the period ended 31 May 2026, detailing modest equity movements and confirming compliance with Hong Kong Stock Exchange public-float requirements.

Key share capital movements • Authorised share capital stayed unchanged at 20.00 billion ordinary shares with a par value of HKD 0.10, equivalent to HKD 2.00 billion. • Issued share count rose by 0.54 million shares to 4.07979 billion, reflecting a 0.01% expansion. No treasury shares were held at month-end. • The increase stemmed from the exercise of 539,000 options under the 20 December 2022 Share Option Scheme, generating HKD 0.16 million in cash proceeds.

Option scheme update 1) April 2025 grant (exercise price: HKD 0.301) – 539,000 options were exercised and 546,000 were cancelled, leaving 56.02 million options outstanding.

2) May 2026 grant (exercise price: HKD 0.594) – 70.56 million options were granted; 210,000 were cancelled, resulting in 70.35 million options outstanding.

Total options outstanding under the 2022 scheme stand at 126.37 million, with capacity to issue or transfer up to 269.06 million shares upon future exercises.

Regulatory confirmations • Wison Engrg affirmed that its public float comfortably satisfies the minimum 21.87% requirement under Main Board Rule 13.32B. • The company confirmed full compliance with all listing rules and regulatory obligations relating to the month’s share movements.

Outlook implications While the additional 0.54 million shares have a negligible dilutive effect (approximately 0.01% of issued share capital), the sizeable pool of 126.37 million outstanding options—representing roughly 3.1% of current issued shares—points to potential future dilution if exercised. The company’s maintenance of a compliant public float provides flexibility for any subsequent equity activities.
