Rockhopper Exploration plc (AIM: RKH), the oil and gas company with key interests in the North Falkland Basin, announces the results of its Open Offer to Qualifying Shareholders, itself announced on 27 August 2026 and which, in accordance with its terms, closed for acceptances at 11.00 a.m. on 15 September 2026.
The Company is pleased to announce that valid acceptances were received from Qualifying Shareholders for a total of 24,242,324 Open Offer Shares under the Open Offer, representing a take-up of approximately 118% per cent. of the 20,529,259 Open Offer Shares available under the Open Offer.
Qualifying Shareholders who have validly applied for Open Offer Shares will receive their full basic entitlement. Applications for New Ordinary Shares under the Excess Application Facility have been scaled back on a pro rata basis, in accordance with the terms of the Open Offer as outlined in the Circular.
Accordingly, the Open Offer has raised total gross proceeds of approximately US$20 million (approximately £14.4 million) through the issue of a total of 20,529,259 Open Offer Shares.
Admission and dealings
The Open Offer Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with each other and with the Existing Ordinary Shares, including the right to receive all dividends and other distributions declared, made or paid after the date of Admission. Application has been made to the London Stock Exchange for the Open Offer Shares to be admitted to trading on AIM ("Admission"). Dealings in the Open Offer Shares and Admission are expected to take place on or around 8.00 a.m. on 18 September 2026.

This announcement contains (or may contain) certain forward-looking statements with respect to certain of the Company's plans and its current goals and expectations relating to its future financial condition and performance and which involve a number of risks and uncertainties. The Company cautions readers that no forward-looking statement is a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statements.
