“These achievements highlight Murphy’s ability to create value across exploration, appraisal and development,” stated Eric M. Hambly, President and Chief Executive Officer. “Bubale West-1X and Lac Da Trang North-1X further expand our resource potential, while development progress at Lac Da Vang and Chinook #8 demonstrate our ability to efficiently convert resources into production and cash flow. Together, these results strengthen our portfolio and position Murphy to create long-term shareholder value.”

Côte D’ivoire

The Bubale West-1X well in Block CI-103 offshore Côte d’Ivoire was drilled to a total measured depth of approximately 19 357 ft (5900 m) in 9039 ft (2755 m) of water and encountered approximately 88 feet (27 m) of net oil pay in the Turonian reservoir. Additional hydrocarbons were also encountered in the deeper Albian reservoir.

Preliminary analysis of logs and fluid samples indicates high-quality oil. Information obtained from the well will be integrated with existing subsurface data to optimise the remaining appraisal program at Bubale.

Murphy’s subsidiary, Murphy CI-103 Oil Co., Ltd., holds an 85% working interest in Block CI-103 and serves as operator. Société Nationale d’Opérations Pétrolières de la Côte d’Ivoire (PETROCI) holds the remaining 15% working interest.

Vietnam

Murphy achieved first oil from the Lac Da Vang field in Block 15-1/05 offshore Vietnam on 27 September 2026. The development is expected to ramp up through 2028 as additional wells are brought online, with net peak production of approximately 10 - 15 MBOEPD in 2028 - 2029.

The achievement of first oil represents a major milestone in Murphy’s Vietnam strategy and establishes a new source of production and cash flow from the Company’s offshore portfolio.

Murphy also announced a successful exploration result at the Lac Da Trang North-1X well in Block 15-1/05, which encountered 131 ft (40 m) of net oil pay. The well was drilled to a total measured depth of approximately 12 579 ft (3834 m) in 147 ft (45 m) of water.

The Company and its partners will evaluate the Lac Da Trang North-1X data and assess potential appraisal and development options. Importantly, the now-producing Lac Da Vang asset provides nearby infrastructure for a potential tieback of the Lac Da Trang North discovery, creating a pathway to a capital-efficient, shorter-cycle development.

Murphy’s subsidiary, Murphy Cuu Long Bac Oil Co., Ltd., serves as the operator of Block 15-1/05, holding a 40% working interest. PetroVietnam Exploration Production Corporation Ltd. holds a 35% working interest and SK Earthon Co. Ltd. holds the remaining 25%.

Gulf of America

The Chinook #8 development well in Walker Ridge Block 425 is now online and producing through the Pioneer floating production, storage and offloading vessel (FPSO) in the Cascade-Chinook field. Consistent with pre-drill expectations, the well achieved an initial gross production rate of approximately 15 MBOEPD.

Murphy, through its subsidiaries, holds an 86.7% working interest in Chinook #8. Petrobras America Inc. holds the remaining 13.3% through its ownership interest in MP GOM.
