of a combination of OBN and streamer acquisition services. The parties plan to
collaborate on seismic acquisition projects utilizing TGS streamer and OBN crews
for exploration and development projects. The CA will also deepen the
relationship between Chevron and TGS and drive collaboration on technology
development in a wide range of geophysical areas from survey design, acquisition
technology, data collection, and data integration. The previously announced St
Malo 4D OBN reservoir monitoring contract in the Gulf of America, will be
included in this agreement and will kick start the collaboration immediately.

Kristian Johansen, CEO of TGS, commented, “We are thrilled to announce a major
milestone in our commitment to evolving the global marine seismic market: the
signing of the global Capacity Agreement (CA). Chevron, a true industry explorer
and long-term client, is ideal for this strategic collaboration. This agreement
not only provides crucial utilization and visibility for both parties but also
creates an opportunity for collaboration across our wider service portfolio. Our
shared focus on new frontier areas makes us highly complementary, and we are
excited to immediately begin supporting Chevron’s global exploration and
reservoir management strategies”.

TGS Announces Pelotas Norte Phase I Multi-client Survey Offshore Brazil

OSLO, Norway (17 November 2025) - TGS, a global leader in energy data and
intelligence, is pleased to announce Pelotas Norte Phase I multi-client 3D
survey in the Pelotas Basin, offshore southern Brazil. Phase I will encompass
…

Vis børsmeldingen

approximately 14,800 square kilometers across 21 exploration blocks, the
majority of which lie in un-held acreage expected to be included in upcoming bid
rounds.

A Ramform Titan-class vessel is scheduled to mobilize for the survey later in
Q4, with project duration running into Q3 2026. The vessel is utilizing TGS
GeoStreamer(®) technology, delivering high-resolution 3D seismic data delivery.
The project is supported by industry funding.

The Pelotas Basin features early basin carbonates and passive margin clastic
sequences, including three organic-rich intervals of Albian, Turonian and
Paleocene ages. The basin attracts significant industry interest driven by its
geological similarities to the conjugate margin and the proven hydrocarbon
systems of West Africa.

Kristian Johansen, CEO of TGS, commented: “Exploration activity in the Pelotas
Norte Basin is accelerating, with several major oil companies increasing their
presence and commitment to the area. The Pelotas Norte Phase I multi-client
survey significantly expands our seismic coverage. By leveraging our advanced
acquisition capabilities and imaging expertise this survey will help our clients
to better understand the basin’s geological structures and derisk future
exploration activities. Following the announcement of two large multi-client
surveys in the Equatorial Margin earlier in Q3, the addition of Pelotas Norte
Phase I brings the number of Ramform Titan-class vessels working offshore Brazil
to three for the remainder of this year and well into next.”

TGS Announces New OBN Multi-client Survey in the Gulf of America

OSLO, Norway (15 January 2026) - TGS, a leading provider of energy data and
intelligence, is pleased to announce APEX 1, a first-of-its-kind, next-
generation multi-client long-offset Ocean Bottom Node (OBN) acquisition campaign
…

Vis børsmeldingen

in the Gulf of America. Node deployment for APEX 1 commenced in December 2025,
and acquisition is expected to be completed in late Q2 2026. Early products are
expected in Q3 2026 and final data delivery Q4 2027.

APEX 1 sets a new benchmark for large-scale long offset multi-client seismic by
deploying a denser node grid than previous ultra-long offset OBN programs and by
being designed as a stand-alone exploration dataset, without reliance on
underlying streamer seismic coverage.

APEX 1 is enabled by TGS’ Gemini™ enhanced frequency source and leverages the
TGS’ deep expertise in long-offset OBN acquisition, processing, and Dynamic
Matching FWI (DM-FWI). The combination of dense node spacing, ultra-long
offsets, and advanced imaging workflows is designed to deliver a step-change in
subsurface resolution, velocity accuracy, and geological confidence for
exploration and appraisal.

This survey creates a highly flexible, future-proof exploration dataset that
supports a wide range of geological objectives. The approach opens new
opportunities for operators to deploy one of the industry’s most powerful
exploration tools, not only in the Gulf of America, but also in other offshore
basins worldwide.

The project is supported by industry funding.

Kristian Johansen, CEO of TGS, commented: “TGS continues to push the boundaries
of what is possible in multi-client seismic. APEX 1 is the result of
collaboration across the entire company, from acquisition and imaging to
commercial and technology teams, and reflects our ability to listen to our
customers and respond with innovative, high-impact solutions. At a time when
efficiency, data quality, and decision confidence matter more than ever, APEX 1
demonstrates TGS’ commitment to delivering unmatched value and reinforcing our
position as the leading innovator in seismic technology. We are proud of what
this project represents today and excited about the opportunities it unlocks for
our customers globally.”

client campaign in the Gulf of America.

Commencing earlier this month, Engagement 9 covers 161 OCS blocks in the Walker
Ridge protraction area, one of the Gulf of America’s most prolific deepwater
provinces. This new dataset is expected to deliver step change improvements in
subsurface illumination across a region known for its structural complexity and
deep hydrocarbon potential. Implementation of a low frequency source enables
richer low frequency content that significantly enhances FWI and long wavelength
velocity model building.

The project’s areal coverage includes several of the basin’s most significant
producing assets, including Stones, Jack, St. Malo, and Cascade, providing
operators with a modern, high quality imaging uplift across established
production corridors. In addition to supporting field development and
optimization efforts, Engagement 9 is positioned to unlock infrastructure-led
exploration opportunities, offering clients greater subsurface confidence
adjacent to existing infrastructure in a region with a strong commercial track
record.

Acquisition is projected to conclude in July 2026, with final data products
anticipated for release in H2 2027.

Kristian Johansen, CEO at TGS, commented, “TGS is proud to expand our OBN data
portfolio in the Gulf of America through continued collaboration with SLB.
Engagement 9 reflects our shared commitment to technological innovation and to
delivering the highest value subsurface insight to our customers. With the
application a low frequency source and the strategic coverage of key producing
hubs, this project provides a unique opportunity to drive improved imaging and
future exploration success in one of the world’s most productive deepwater
environments.”

offshore Angola. The survey covers approximately 12,600 line kilometers and
…

Vis børsmeldingen

Ramform Victory commenced operations earlier in Q1. Data acquisition is
estimated to be completed in approximately 100 days, with fast-track products
available in Q3. Full data processing is scheduled for completion in Q2 2027.

The Ultra Profundo multi-client 2D survey marks the first 2D multi-client
acquisition over Angola’s ultra deepwater areas since 2015 and targets a highly
underexplored region. The survey delivers modern, long-offset seismic data
critical for imaging complex pre-salt and top-salt structures as well as basin
floor channel systems, significantly enhancing regional geological
understanding.

Kristian Johansen, CEO of TGS, commented: “Angola’s ultra deepwater margin
represents one of the most exciting frontier exploration opportunities in West
Africa. Our Ultra Profundo multi-client 2D program delivers high-quality seismic
coverage needed to unlock pre-salt and sub-salt potential. By leveraging TGS’
acquisition and imaging capabilities, we will provide high-quality data
supporting future exploration activities.”

TGS announces Q4 2025 results

OSLO, Norway (12 February 2026) - TGS today reports interim financial results
for Q4 2025.

…

Vis børsmeldingen

Financial highlights:

• Q4 Revenues of USD 363 million, driven by strong multi-client performance
  (sales-to-investment of 2.0x for the full year 2025)

• Solid order inflow of USD 598 million in Q4 2025 - total order backlog
  increased to USD 706 million

• Net cash flow of USD 206 million in 2025

• Improved balance sheet resilience by reducing net debt by USD 73 million in
  2025, to USD 427 million

• Stable dividend payment of USD 0.155 per share to be paid in Q1 2026

• 2026 guidance:

  • Multi-client investment in the range of USD 500-575 million supported by
    strong customer commitments, up from USD 447 million in 2025
  • Significant increase in vessel utilization driven by high multi-client
    activity - OBN activity expected to be in-line with 2025
  • Gross operating cost of approximately USD 950 million - Capex at
    approximately the same level as in 2025.

"Considering the difficult market conditions, I am satisfied with our Q4 2025
results. We gained significant traction with customers, achieving an order
inflow of USD 598 million - our best quarter since before the pandemic. Our
multi-client business performed well, and strong momentum at year-end meant our
sales-to-investment ratio met our annual goal of 2.0x. Although contract
revenues in Marine Data Acquisition were affected by reduced proprietary seismic
survey activity, our integrated business model allowed us to improve asset
utilization, thanks to increased demand for multi-client projects. The Imaging
division benefited from a sharpened strategic approach, producing a 65% growth
in pro-forma external revenue for 2025.

Throughout the year, we maintained our focus on cost and capital efficiency,
which led to a substantial reduction in costs. Consequently, we generated a net
cash flow before dividends of more than USD 200 million and lowered net debt to
USD 427 million by year-end, despite revenue declines and challenging market
conditions.

Due to oil price uncertainty and elevated geopolitical risks, we do not expect
notable improvements in market conditions in the near future. However, as the
global oil market is expected to move toward a more balanced state in the latter
part of 2026, and as our clients increasingly prioritize reserve health and
exploration for new resources, I am optimistic about a sustained recovery in
demand over the longer term," says Kristian Johansen, CEO of TGS.

Management presentation
CEO Kristian Johansen and CFO Sven Børre Larsen will present the results at
09:00 a.m. CET today at Thon Hotel Vika Atrium, Munkedamsveien 45, Oslo, Norway.

The presentation is open to the public and will be webcasted live.
