Press Release
  Seismic Technology Strengthens Competitiveness, Elnusa Secures Continued Non-Captive
                                Projects in South Sumatra
Jakarta, 3 September 2026 – PT Elnusa Tbk (IDX: ELSA), an integrated energy services company and part of Pertamina’s Upstream Subholding, continues
to strengthen its presence in the non-captive market through technological capabilities and operational excellence. Elnusa has once again earned the trust
of a customer outside the Pertamina Group to undertake two 3D Seismic Survey projects covering a total area of approximately 150 km² in Musi Banyuasin
Regency, South Sumatra. Targeted for completion in early 2027, these projects follow two previous 3D seismic projects covering 365 km² in adjacent
areas.

The continuation of projects from the same customer reflects confidence in Elnusa’s ability to manage seismic operations with a high degree of technical
and operational complexity. Cumulatively, the series of projects covers approximately 515 km², further strengthening the Company’s track record in the
non-captive geoscience market. Expanding beyond the Pertamina ecosystem forms part of Elnusa’s strategy to broaden its customer base, optimize the
utilization of its assets and competencies, and unlock new sources of growth.

Elnusa Corporate Secretary, Rustam Aji, said that continued customer confidence demonstrates that the capabilities developed by Elnusa are competitive
in the external market. “For us, non-captive projects serve as validation of Elnusa’s competitiveness. Being entrusted once again to undertake projects in
adjacent areas demonstrates that the technology, personnel competencies, and execution quality we have developed are capable of delivering value to
our customers. Our strategy is to continue converting these strengths into market opportunities and sustainable business growth,” said Rustam.

In executing the projects, Elnusa is optimizing the STRYDE Nimble Seismic System as part of the Company’s efforts to strengthen its next-generation
seismic technology capabilities since early 2026. Previously, Elnusa made a strategic investment in 25,000 STRYDE Range+ nodes, supported by the STRYDE
Nimble System and STRYDE Mini System. This combination of technologies provides greater flexibility in survey design and execution, enables
simultaneous project operations, and optimizes resource utilization for both 2D and 3D seismic acquisition.

The nodal technology also supports higher-density seismic data acquisition with improved data quality, accelerates survey cycles, and enhances
operational efficiency. Its compact and flexible design provides an advantage when operating in complex field conditions and areas with limited access.
For Elnusa, technology investment is not only aimed at strengthening technical capabilities, but also at improving asset productivity, enhancing service
competitiveness, and increasing the Company’s ability to capture broader market opportunities.

These advantages are particularly relevant to the characteristics of the two projects in Musi Banyuasin Regency, which traverse diverse environments
ranging from forest areas and rivers to mining areas and residential communities. Such conditions require adaptive survey planning, readiness of personnel
and technology, as well as disciplined operational management. Elnusa also ensures that Health, Safety, Security & Environment (HSSE), regulatory and
permitting compliance, as well as communication and engagement with local governments, communities, and other local stakeholders, remain integral
to every stage of project execution.

The strengthening of Elnusa’s geoscience business is aligned with the Company’s strategic direction to position technology and innovation as key drivers
of growth. Elnusa’s seismic capabilities are supported not only by advanced technology, but also by extensive experience in managing various onshore
and offshore projects of different scales and characteristics. This combination of technology, people, and execution capability represents a competitive
advantage for the Company in expanding market penetration both within and beyond the Pertamina ecosystem.

“Going forward, we want to ensure that every technology investment generates increasingly optimal economic value. This means technology must go
beyond enhancing capabilities; it must improve efficiency, address customer needs, expand market reach, and ultimately create long-term value for the
Company and its shareholders,” added Rustam.

Through the strengthening of seismic technology and expansion into the non-captive market, Elnusa continues to reinforce its positioning as a technology-
driven energy services company. This strategy complements Elnusa’s strong business presence within the Pertamina ecosystem while building an
increasingly diversified customer base, thereby supporting the Company’s competitiveness and sustainable growth.
