Gulf Keystone and ShaMaran have agreed to merge through a share swap valuing ShaMaran's equity at about $601 million, according to ShaMaran's announcement, alongside an investment announcement expanding its operations into federal Iraq. The transaction consideration will be paid in new Gulf Keystone shares issued to ShaMaran shareholders, based on an exchange ratio specified in the merger agreement between the companies. Under the announced terms, ShaMaran shareholders will receive 0.07533958 new Gulf Keystone shares for each ShaMaran share held at completion. Shareholders of each company will own about 50% of the combined entity, according to the structure ShaMaran outlined in its statement on the agreement. Gulf Keystone will remain the "surviving legal entity" under Bermuda law, according to the announcement's description of the legal structure that will continue after the merger.

The financial arrangements include Gulf Keystone's intention to make a special distribution of $50 million to its existing shareholders on completion of the transaction, according to ShaMaran's announcement outlining the merger terms. The planned distribution remains subject to legal approvals and approval by Gulf Keystone's board as part of the arrangements accompanying completion of the agreement between the companies. Comparing the share-swap consideration with the closing price of ShaMaran's Swedish depositary receipts on the eve of the announcement, the premium offered to the company's shareholders is 22.9% before adjusting for the special distribution. After adjusting for the planned distribution to Gulf Keystone shareholders, the consideration premium falls to 13.5% relative to the same pre-announcement closing price. Both premium calculations are based on the price of ShaMaran's Swedish depositary receipts in that session, while the cash distribution is for Gulf Keystone's existing shareholders.

Alongside the merger agreement, ShaMaran announced an investment in Hamrin that adds federal Iraq to the scope of the transaction, alongside oil assets in the Kurdistan Region of Iraq. The company said in its investment announcement that it would own a 25% stake in HKN Hamrin Ltd., the company associated with the field project. The project company holds the development and production contract for the Hamrin field in federal Iraq, while HKN operates it under the arrangements announced by ShaMaran. The first phase of the development plan targets an increase in the field's production to about 60 thousand barrels per day by 2028, according to the investment statement accompanying the merger announcement. That target relates to Hamrin's production under its development plan, while ShaMaran's announced participation consists of a stake in the project company holding the contract.

To fund its commitments, ShaMaran is considering a bond issue of up to $200 million, according to its announcement on the investment in Iraq and the planned accompanying financing. It intends to use the proceeds of the proposed issue to refinance its outstanding bonds and fund the Hamrin investment, as well as for general corporate purposes listed in the announcement's use of proceeds. ShaMaran described the financing as a "proposed bond issue," leaving the fundraising as a step the company is considering alongside its announced investment. On costs at the combined entity, the companies estimate that the merger will generate annual general and administrative expense savings of up to $5 million, according to the agreement announcement. Those estimated savings relate to combining the companies' operations after completion, while the financing ShaMaran is considering would cover existing debt, the field investment and general corporate needs.

Against the backdrop of developments in ShaMaran's operations, the company also announced the start of payments of accumulated supplementary receivables on export sales from September to December 2025. ShaMaran said in a statement on the payments that Iraq's State Organization for Marketing of Oil, SOMO, had allocated an additional cargo to compensate producers based on international prices. The announced payments concern supplementary receivables arising from exports during that period, under the compensation arrangements addressed in the company's statement on the start of payments. On the equity market front, Gulf Keystone intends to move to Oslo's main market, according to the merger announcement's description of the company's listing arrangements. Its plan also includes subsequently ending its London listing, a change the company intends to make to its listed shares alongside the transaction's corporate structure.

The announced shareholder milestones begin with the expected publication of the merger information document around 1 December 2026, according to the indicative timetable ShaMaran provided in its announcement of the agreement between the companies. That date precedes the shareholder meetings to vote on the transaction, which the companies are expected to hold around 22 December 2026, according to the same timetable. The transaction will be put to each company's shareholder meeting for a vote as part of the process the companies have outlined for proceeding with the proposed share swap and merger. Following those milestones, Gulf Keystone and ShaMaran expect to complete the merger in mid-2027, subject to satisfaction of the conditions governing implementation of their announced agreement. The dates for publication of the document, the shareholder meetings and completion remain part of the transaction's indicative timetable, with the companies linking their completion expectation to fulfilment of its conditions.
