Sunshine Oilsands Ltd. has circulated a proxy form for a special meeting set for 11:30 a.m. on 24 June 2026 in Hong Kong (9:30 p.m. on 23 June 2026 in Calgary).

The agenda features one ordinary resolution:

1. Approve, confirm and ratify the Placing Agreement signed on 21 December 2025 between the company and its placing agent, together with all related transactions. 2. Grant a specific mandate empowering directors to allot and issue up to 114.28 million new Class “A” common voting shares under the agreement.

Key administrative points:

• Shareholders on the Hong Kong register must lodge proxy documents with Computershare Hong Kong Investor Services by 11:30 a.m. on 22 June 2026 (Hong Kong time). • Shareholders on the Canada register must submit proxies to Odyssey Trust Company by 4:30 p.m. on 19 June 2026 (Toronto time).

Completion and delivery of a proxy does not preclude shareholders from attending and voting in person. The proxy defaults to voting “FOR” the resolution unless otherwise instructed.
