Gulf Keystone merger terms and shareholder consideration
The companies’ proposed combination agreement provides for a statutory merger in Bermuda, where both businesses are incorporated, with Gulf Keystone surviving as the legal entity. Both boards have unanimously approved the proposed transaction.
The approximately $601 million equity value for ShaMaran is based on Gulf Keystone’s closing share price of 225 pence on October 19, 2026, and the exchange rates specified in the announcement. It is a share-based transaction value, not a cash payment to ShaMaran investors.
The companies put the consideration at a 22.9% premium to ShaMaran’s October 19 closing price, based on its Swedish depository receipts. After adjusting for Gulf Keystone’s intended special dividend, that premium falls to 13.5%. The distinction matters because the dividend is intended for existing Gulf Keystone shareholders rather than incoming ShaMaran holders.
The $50 million dividend remains subject to applicable Bermuda law, Gulf Keystone’s bye-laws and board approval. The companies also intend to formalise the combined business’s future distributions policy around completion.

Four-field portfolio would broaden the operating base
The merger would bring Gulf Keystone’s operated Shaikan field interest together with ShaMaran’s non-operated interests in Atrush and Sarsang in the Kurdistan Region of Iraq. It would also include ShaMaran’s separately announced investment in the Hamrin field in Federal Iraq.
Gulf Keystone holds a 61.5% working interest in Shaikan, while ShaMaran holds 50% of Atrush and 18% of Sarsang. ShaMaran’s Hamrin investment is a 25% shareholding in HKN Hamrin Ltd., the company holding the field’s development and production contract.
Management presents the combination as a way to broaden cash generation and support development spending across the portfolio. Those benefits remain expectations rather than completed operating results. The two companies will continue to operate independently until closing.
Oslo listing plans change the shareholder arrangements
Gulf Keystone intends to move its primary listing to the Euronext Oslo Børs main market and, in due course, discontinue its London listing. ShaMaran’s existing share and Swedish depository receipt listings would cease in connection with completion.
The announcement identifies the transaction as a reverse takeover under UK Listing Rules. Gulf Keystone therefore expects its existing UK listing category to be cancelled at completion; a continuing London listing would require an application for admission to another category.
ShaMaran investors holding shares through Norway’s securities depository would receive Gulf Keystone shares directly. Holders who retain Swedish depository receipts through closing would instead receive unlisted Gulf Keystone depository receipts under a temporary conversion programme.
Approvals and closing remain outstanding
The largest shareholder of each company has indicated an intention to support the deal. The Lundin family holds approximately 25.6% of ShaMaran, while Lansdowne Partners manages holdings representing approximately 13% of Gulf Keystone. These indications do not replace the required shareholder votes.
Completion is not conditional on financing because the merger consideration consists entirely of newly issued shares. Separately, ShaMaran contemplates refinancing its 2029 bond, with approximately $144 million outstanding, while Gulf Keystone is considering a bond issue to fund some Shaikan development expenditure.
Conclusion
The next scheduled disclosure is the merger information document, expected around December 1, ahead of the proposed shareholder meetings. The share exchange, dividend and listing changes remain contingent on the transaction progressing to completion.
