Operational & Corporate Update and Notice of Annual General Meeting

Gulf Keystone, a leading independent operator and producer in the Kurdistan Region of Iraq (“KRI” or “Kurdistan”), is today providing an update on operational and corporate activity and the Company’s upcoming 2023 Annual General Meeting (“AGM”).

Operational & Corporate Update

Following the shut-in of the Iraq-Turkey pipeline on 25 March 2023, production from the Shaikan Field remains shut-in. The suspension of exports has resulted in a gross production deferment to date of around 2.9 million barrels, or approximately 8,000 bopd on a full-year basis.

While no official timeline to restart pipeline operations has been publicly announced, the Company continues to believe that the suspension of exports will be temporary. We are encouraged by the announcement from the Kurdistan Regional Government (“KRG”) on 11 May 2023 that it has reached an agreement with the Iraqi government on measures to allow the resumption of oil exports through Turkey and that Iraq's State Oil Marketing Organization (“SOMO”) has officially requested Turkish authorities to allow the Kurdistan Region’s oil exports via the country's Ceyhan port. The Company remains ready to resume production immediately.

The Company continues to seek clarity from the KRG on when consistent monthly oil sales payments will resume and when the current overdue receivables for the months of October 2022 to February 2023, totalling $128 million net on the basis of the KBT pricing mechanism, will be paid.

The Company remains focussed on preserving liquidity and continues to reduce capital expenditures and costs across the business, while maintaining a strong focus on safety and long-term asset reliability.

As previously announced, the Board has been considering the proposed final 2022 ordinary annual dividend of $25 million and, while the importance of distributions to shareholders is recognised, it believes that it is prudent to cancel the dividend. Once regular payments from the KRG resume, the Board will consider the reinstatement of dividends in line with its financial framework, which includes an assessment of the Company’s expected liquidity, cash flow generation and investment needs.

GKP will provide further updates to the market, as appropriate.
