Correction: TGS Q3 2021 Earnings Update

OSLO, Norway (8 October 2021) - Based on preliminary reporting from operating
units, TGS management expects net IFRS revenues* for the third quarter of 2021
to be approximately USD 200 million, compared to USD 58 million in Q3 2020. Net
…

segment revenues* are expected to be approximately USD 61 million, compared to
USD 81 million in Q3 2020.

Kristian Johansen, CEO at TGS, commented: “The market conditions for multi-
client seismic data continues to be very challenging. E&P companies’ 2021
budgets do not allow for much spending beyond what was committed at the start of
the year, meaning that the recent oil price increases so far have had little
impact on spending levels. However, with the current oil price, the value
proposition of exploration for new oil and gas resources is very attractive. As
such, we remain optimistic that spending on exploration related data and
services will improve as E&P companies are entering a new budget cycle with
lower levels of legacy commitments. Meanwhile, the financial position stays
healthy with approximately USD 200 million of cash and no interest-bearing debt
on the balance sheet.”

TGS will report the Q3 2021 financial results on 28 October 2021.

• Following notification from The Financial Supervisory Authority of Norway
  (Finanstilsynet) TGS will from 2021 increase emphasis on IFRS in its financial
  reporting to the market. The Company will continue to provide segment
  information for historic comparison and as alternative performance measures of
  the business as such measures are commonly used throughout the industry, and
  TGS’ management believes they better reflect the ongoing activity in projects-
  in-progress. The main difference between IFRS and Segment reporting relates to
  revenue recognition. Under IFRS revenue recognition generally is deferred until
  project completion and delivery to the customer when performance obligations are
  met. Under Segment reporting, net revenue from projects-in-progress is
  recognized based on Percentage of Completion (POC). Revenue recognition has
  subsequent effects on the recognition of amortization of the multi-client
  library. Please see the annual report for a complete description of the
  Company’s accounting principles.

Adjustments between preliminary IFRS and Segment revenue numbers for Q3 2021:

Preliminary IFRS reported revenue: USD 200 million

• Revenue recognized from performance obligations met during Q3 for completed
  projects: USD 163 million

• Revenue recognized under POC during Q1: USD 24 million
  = Preliminary net segment reported revenue: USD 61 million

Vis børsmeldingen

development of the energy industry in the Republic of Suriname. The agreement
allows the consortium to acquire, promote and license multi-client seismic
programs, including new 3D acquisition and legacy data reprocessing, in the
shallow water acreage offshore Suriname.

Suriname’s shallow offshore acreage includes three blocks recently awarded, and
current open acreage is slated to be offered in a competitive bid round for
2023. The new seismic data from the consortium’s multi-client programs will be
instrumental in accurately delineating the prospectivity and potential of this
underexplored area and is on trend with the recent material discoveries
announced on the prolific block 58.

Plans are in place to start acquiring the new 3D seismic data in the shallow
offshore area from Q4 2021 with first products being made available during H1
2022.

Kristian Johansen, CEO at TGS, commented: “We are pleased to announce entry to
Suriname to continue successful evaluation of the region’s potential. With this
exciting multi-client agreement, the consortium will play a key part in
encouraging and enhancing future exploration in Suriname, ultimately helping our
customers de-risk their investment opportunities.”

Sophie Zurquiyah, CEO, CGG, said: “CGG brings its multi-client expertise and
high-end imaging technology to this major new program that marks our return to
the Guyana-Suriname basin after our successful campaign in the Stabroek block.
The resulting exceptional data will bring new insight and potentially extend the
trend of recent significant discoveries to the shallow waters of Suriname.”

Luo Junchao, President of BGP Offshore, commented, “We are excited to be part of
this innovative and pioneering consortium with TGS and CGG providing the
industry with a world-class “drill ready” dataset. BGP Offshore will deploy its
state-of-the-art 3D vessel BGP Prospector on phase 1 of this project.”

TGS Announces Q3 2021 Results

OSLO, Norway (28 October 2021) - TGS today reported interim financial results
for Q3 2021.

…

Vis børsmeldingen

Net IFRS revenues amounted to USD 200 million in Q3 2021, an increase of 243%
compared to Q3 2020. EBITDA was USD 167 million, and the operating result was
USD 36 million, compared to USD 40 million and USD -90 million, respectively, in
Q3 2020.

Net segment revenues (1) amounted to USD 61 million in Q3 2021, compared to USD
81 million in Q3 2020. Segment EBITDA was USD 28 million versus USD 62 million
in the same quarter of 2020, while the segment operating result amounted to USD
-28 million, the same as in Q3 2020.

Free cash flow (2) amounted to USD 6 million in Q3 2021, up from USD 4 million
in Q3 2020. After shareholder distribution of USD 23 million, the cash balance
totaled USD 190 million at 30 September 2021. For the first nine months of
2021, free cash flow amounted to USD 108 million, compared to USD -4 million in
2020.

The solid financial position allows TGS to maintain the quarterly dividend at
USD 0.14 per share and continue its share repurchase program with a remaining
value of up to USD 7 million.

“The market conditions for multi-client seismic data continue to be challenging.
E&P companies’ 2021 budgets do not allow for much spending beyond what was
committed at the start of the year, meaning that the recent oil price increases
so far have had little impact on spending levels. However, with the increasing
oil price combined with low cost of exploration related services, the value
proposition of exploration is approaching all-time-high levels, and we are
starting to see some early signs of a recovery,” says Kristian Johansen, CEO of
TGS. “I’m pleased with the progress seen in our New Energy Solutions business,
where we expect to generate approximately USD 10 million of pro-forma revenues
this year.”

A live presentation and webcast of the results and business update, featuring
CEO Kristian Johansen and CFO Sven Børre Larsen, will be held at Skøyen Atrium,
Askekroken 11, 0277 Oslo, Norway (first floor) at 9:00 am CEST.

Notes
1 - IFRS versus Segment Reporting:
The main difference between IFRS and Segment reporting relates to revenue
recognition. Under IFRS revenue recognition generally is deferred until project
completion and delivery to the customer when performance obligations are met.
Under Segment reporting, net revenue from projects-in-progress is recognized
based on Percentage of Completion (POC). Revenue recognition has subsequent
effects on the recognition of amortization of the multi-client library. Please
see annual report for a complete description of the Company’s accounting
principles.

• Revenue recognized from performance obligations met during Q3 for completed
  projects: USD 163 million

• Revenue recognized under POC during Q3: USD 24 million
  = Preliminary net segment reported revenue: USD 61 million

Differences in EBIDTA and operating result between IFRS and segment reporting
are caused by the aggregate differences in revenues and the resulting impact on
amortization.
