OmniVision Integrated Circuits Group, Inc. disclosed a minor contraction in its A-share capital structure for April 2026, reflecting simultaneous employee option exercises, minimal convertible-bond conversions and a targeted repurchase on the Shanghai Stock Exchange.

Opening position (9 April 2026) • Issued A shares (excluding treasury): 1.20482 billion • Treasury shares: 5.59 million • Total issued shares: 1.21041 billion

New share issuance • Employee stock-option exercises under the 2023 First and Second Phase Stock Option Incentive Plans produced 52,435 new A shares at an exercise price of RMB 78.01 each, adding roughly 0.004% to the share count. • Conversion of the company’s December 2026 convertible bonds resulted in 249 new shares at RMB 159.12 apiece. • Aggregate new shares issued: 52,684.

Share buyback • On 30 April 2026, OmniVision repurchased 417,000 A shares on the Shanghai Stock Exchange at prices ranging from RMB 98.14 to RMB 98.80, for a total outlay of RMB 41.06 million. The volume-weighted average price was approximately RMB 98.49 per share. All repurchased shares are being held as treasury stock.

Closing position (30 April 2026) • Issued A shares (excluding treasury): 1.20446 billion • Treasury shares: 6.00 million • Total issued shares: 1.21046 billion

Net impact • The company’s outstanding A-share float declined by 364,316 shares, equivalent to 0.03% of the opening balance, primarily due to the buyback offsetting the modest option-driven increase. • Treasury stock grew by 417,000 shares, providing additional flexibility for future share-based incentives or potential cancellation.

All corporate actions were executed under board authorisation and in compliance with Hong Kong Listing Rules and Shanghai Stock Exchange regulations, as confirmed in the filing.
