Press Release
     Elnusa Strengthens Strategic Role through Dual Completion with PHR Zona 4 to
                        Support Pertamina's Production Targets

Jakarta, 22 July 2026 - PT Elnusa Tbk (Elnusa), an integrated energy services company and part of Pertamina's Upstream Subholding, continues to
strengthen its role as a strategic partner of Pertamina Hulu Rokan (PHR) Zona 4 through the implementation of Dual Completion technology at Adera
Field. This collaboration forms part of Pertamina's broader initiative to increase national oil and gas production while reinforcing Indonesia's energy
security.

The Dual Completion implementation supported by Elnusa is part of PHR Zona 4's field development strategy to optimize the potential of mature oil and
gas fields. The technology complements various development initiatives, including development drilling, step-out drilling, and reservoir optimization, to
improve the efficiency of hydrocarbon recovery.

In supporting the implementation, Elnusa leveraged its capabilities in Well Intervention & Completion, Engineering Services, and field operation execution
while maintaining the highest Health, Safety, Security, and Environment (HSSE) standards. These capabilities enabled completion activities to be carried
out safely, on schedule, and in accordance with operational standards, contributing to the optimization of production at PHR Zona 4 while creating added
value for Pertamina's upstream field development.

PT Elnusa Tbk's Operations Director, Andri Haribowo, stated that the collaboration with PHR Zona 4 reflects Elnusa's commitment to continuously
delivering operational solutions that create value for Indonesia's upstream oil and gas industry, "The successful implementation of Dual Completion with
PHR Zona 4 demonstrates that strong collaboration between operators and energy service companies can deliver more productive and efficient
operations. Elnusa's capabilities have become an integral part of Pertamina's efforts to optimize field development through strategic partnerships. This
collaboration reflects how national expertise can contribute meaningful value to the sustainability of Indonesia's upstream oil and gas operations," said
Andri.

Through the implementation of Dual Completion at the BNG-D14 well in Adera Field, two productive reservoirs can be produced simultaneously through
a single wellbore without requiring separate wells for each reservoir interval. This approach improves field development efficiency, reduces the need for
additional well interventions, and maximizes the utilization of productive reservoirs, making it an effective solution for mature oil and gas fields.

The application of Dual Completion under PHR Zona 4's field development program has delivered an additional production of approximately 480 barrels
of oil per day (BOPD) and 3.3 million standard cubic feet of gas per day (MMSCFD), exceeding the initial target of 186 BOPD and 1.09 MMSCFD. This
technology has become one of the key approaches for optimizing mature fields through more efficient reservoir utilization. Following this successful
implementation, the technology is planned to be deployed in additional wells, including GNK-PD80 and BNG-B7.

According to Andri, the achievement highlights the importance of close collaboration between operators and energy service providers in creating safer,
more effective, and sustainable operations, "We believe that increasing oil and gas production is driven not only by technology, but also by strong
collaboration among entities within the Pertamina Group. Backed by our experience and technical capabilities, Elnusa remains committed to supporting
PHR and other Pertamina Group entities through reliable, innovative, and operational excellence-driven services to help achieve national oil and gas
production targets while strengthening Indonesia's energy security," Andri concluded.

Moving forward, Elnusa will continue strengthening its synergy with Pertamina Group by delivering integrated energy services that support higher field
productivity, accelerate technology implementation, and promote operational excellence. This commitment reaffirms Elnusa's role as Pertamina's
strategic partner in developing more efficient, sustainable, and competitive upstream operations while contributing to Indonesia's long-term energy
security.
