“The successful bond raise will provide us with the balance sheet strength and flexibility to deliver production growth from the Shaikan Field as we prepare to embark on a multi-year development and drilling programme from 2027. This new bond follows ShaMaran’s recent successful $200 million issue and, on completion of the contemplated merger, will put the combined company in a strong position to unlock the significant growth potential of its diversified asset base.”
