Press Release
     Elnusa Strengthens Investment in Upstream Oil and Gas Business to Capture
                 Growth Opportunities and Enhance Long-Term Value
Jakarta, June 25, 2026 – PT Elnusa Tbk (Elnusa), a subsidiary of PT Pertamina Hulu Energi within Pertamina’s Upstream Subholding, continues to reinforce its
long-term growth foundation through the realization of strategic investments in its upstream oil and gas services business line as of May 2026. This initiative
forms part of the Company’s strategy to enhance service capacity, expand technological capabilities, and capture market opportunities amid increasing national
oil and gas exploration and production activities.

The investments realized by Elnusa are focused on strengthening the Company’s core competency as an integrated energy services provider, particularly in the
upstream oil and gas services segment, which has consistently been one of the Company’s key performance contributors. Through a selective, market-driven
approach, these investments are directed at improving competitiveness, increasing asset productivity, and creating sustainable growth drivers.

Within the Marine Site Survey (MSS) line of business, Elnusa has strengthened its Survey Topography & Positioning Services through investments in STPS navigation
equipment. Technological support such as Differential Global Navigation Satellite System (DGNSS), Side Scan Sonar, and Marine Magnetometer enhances the
accuracy of offshore surveys required for rig moving activities, field development, and offshore exploration.

Meanwhile, the Pressure & Pumping Services (PPS) line has been reinforced through the addition of Coiled Tubing Units equipped with the latest monitoring and
modeling technologies. This investment improves well intervention service capacity, which is currently showing promising market prospects in line with increasing
demand for workover activities and production optimization in existing oil and gas fields.

Elnusa has also invested in next-generation Cementing Units to improve operational reliability. This initiative is expected to deliver long-term cost efficiency
while strengthening the Company’s competitive position in cementing services.

In the Non-Seismic Survey segment, Elnusa has expanded its technological capabilities through investment in Passive Geobit C100, supporting more
comprehensive subsurface survey and monitoring needs. In addition, investment in Electric Wireline Logging (EWL) equipment has been made to ensure the
sustainability of offshore cased hole workover and well services, which continue to be essential for customers in the upstream oil and gas sector.

The Director of Business Development of PT Elnusa Tbk, Arief Prasetyo Handoyo, stated that the realization of these investments reflects the Company’s confidence
in the prospects of the upstream oil and gas services industry and Elnusa’s commitment to creating long-term value for its shareholders.

“Our investments are not merely about asset expansion, but represent strategic steps to strengthen capabilities, enhance productivity, and capture growth
opportunities in the upstream oil and gas sector. With a well-measured, market-driven investment portfolio, Elnusa is optimistic about strengthening operational
performance, improving profitability, and delivering sustainable value to all stakeholders,” said Arief.

In line with the increasing national energy demand and ongoing oil and gas field development activities across various regions of Indonesia, Elnusa sees continued
promising growth opportunities in the upstream oil and gas services sector. Accordingly, the Company remains committed to implementing a disciplined and
selective investment strategy, with a focus on enhancing business capacity that directly contributes to revenue and profit growth.

Supported by strong business fundamentals, increasingly advanced technology, and more than five decades of experience in the energy industry, Elnusa is
confident in its ability to further strengthen its position as a strategic partner in the national energy industry while delivering sustainable added value for
investors and all stakeholders.
