("EnQuest" or the "Company")

Malaysia PAC Operator of the Year

10 June 2025

EnQuest Malaysia was the proud recipient of two prestigious awards, including Operator of the Year, at the recent PETRONAS Emerald Awards ceremony in Kuala Lumpur. This is the second consecutive year in which EnQuest has been recognised as the best Petroleum Arrangement Contractor ('PAC') by PETRONAS and the first time in the history of the awards that this accolade has been retained. In addition to the PAC of the Year award, PETRONAS also recognised EnQuest with an award for Abandonment Excellence.

The Emerald Awards celebrate the achievements of upstream operators across various technical and non-technical disciplines. Award recipients were selected based on key criteria, including operational performance, corporate governance, regulatory compliance, and active collaboration with PETRONAS and the wider upstream sector in Malaysia throughout 2024. This year's theme, 'Advancing Progress Towards a Sustainable Future', reflects a collective commitment to sustainability and innovation across the industry, values that are central to EnQuest's global operations.

These awards are further validation of EnQuest's strong reputation in Malaysia, built over ten years of successful operations in the country, and demonstrate the esteem in which the Company's capabilities are held as we continue to deliver diversified growth across South East Asia. EnQuest has announced several key growth initiatives in the region in recent months, including the award of the DEWA PSC and securing the Seligi 1b gas agreement in Malaysia, the acquisition of Harbour Energy's Vietnam business and, most recently, the successful PSC awards at Gaea and Gaea II in Indonesia.

EnQuest has now established a pathway to grow its South East Asian production to more than 35,000 Boepd by the end of the decade, with the opportunity to deliver additional upside across its existing Asia portfolio through field optimisation, organic investment, acquisition and further new country entries.

On the PAC Operator of the Year, Radzif Ahmed, South East Asia General Manager said:

"To receive this recognition once is a great honour. To receive it twice, back-to-back, is a powerful testament to the consistency, capability, and commitment of the EnQuest team, both onshore and offshore. It is also a reaffirmation of the vision we share with PETRONAS in advancing Malaysia's upstream sector. 2024 was a significant year for EnQuest Malaysia; we celebrated our 10 years in Malaysia, the DEWA PSC awards, and enhanced Seligi gas development, and we were proud to continue our track record of HSE excellence with zero lost time injuries. We look forward to deploying our operational excellence as we deliver continued growth in Malaysia and across the region."
