CHK Oil Limited disclosed that, on 11 May 2026, it signed an addendum with Aral Petroleum Capital LLP to prolong their existing memorandum of understanding (MOU) on potential cooperation by six months to 11 November 2026. The extension follows the initial three-month exclusivity period from 10 November 2025 and a prior three-month prolongation that expired on 9 May 2026.

The new addendum, described as the “Second Extension,” removes the original exclusivity clause, allowing either party to engage with other counterparties during or after the extended period. All other terms of the MOU remain unchanged, and additional time has been allotted for continued due diligence and negotiation of definitive terms.

The company reiterated that the MOU is non-binding and imposes no statutory obligations on either side. CHK Oil stated it will issue further announcements if a legally binding agreement is reached, in accordance with Hong Kong Listing Rules.

Shareholders and potential investors are advised to exercise caution when dealing in the company’s shares.
