TGS Q2 2021 Earnings Update

OSLO, Norway (8 July 2021) - Based on preliminary reporting from operating
units, TGS management expects net IFRS revenues* for the second quarter of 2021
to be approximately USD 65 million, compared to USD 66 million in Q2 2020. Net
…

Vis børsmeldingen

segment revenues* are expected to be approximately USD 54 million, compared to
USD 96 million in Q2 2020.

Kristian Johansen, CEO at TGS, commented: “As described in the Q1 2021 report,
the market conditions for multi-client seismic data continues to be very
challenging, and there are no signs of substantial improvements in the near-
term. However, based on dialogue with our largest customers we remain confident
that we will ultimately see a recovery of the market. Meanwhile, our asset-light
business model, robust balance sheet and strong cash flow enable us to take
advantage of strategic opportunities, both in the subsurface data area and in
the New Energy Solutions segment.”

TGS will report the Q2 2021 financial results on 22 July 2021.

• Following recent 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 annual report for a complete description of the Company’s
  accounting principles.

Adjustments between preliminary IFRS and Segment revenue numbers for Q2 2021:

Preliminary IFRS reported revenue: USD 65 million

• Revenue recognized from performance obligations met during Q2 for completed
  projects: USD 36 million

• Revenue recognized under POC during Q1: USD 25 million

= Preliminary net segment reported revenue: USD 54 million

line of Schlumberger, have secured pre-funding for a 6,400 square kilometer
…

Vis børsmeldingen

multi-client 3D survey commencing in October in the Sarawak Basin, offshore
Malaysia.

The survey is the first phase of a multi-year contract awarded by Petronas in
2020 through competitive bidding to acquire and process up to 105,000 square
kilometers of multi-client 3D data over a 5-year period in the Basin.

The first phase of the survey will be acquired by PGS’ Ramform Sovereign using
multi-sensor GeoStreamer technology and is expected to take approximately 4
months.

The survey area covers acreage included in the Malaysia Bid Round 2021 and fast-
track results will be delivered in time for block evaluation. Future acquisition
phases are subject to securing sufficient pre-funding.

Nathan Oliver, Executive Vice President, Sales & Services at PGS commented, “We
are very pleased to commence the first phase of MultiClient acquisition in the
Sarawak basin. By combining the Ramform vessel and our multi-sensor GeoStreamer
technology, the energy industry will get access to high-quality seismic data to
explore this prolific hydrocarbon basin.”

Will Ashby, Executive Vice President, Eastern Hemisphere at TGS, commented,
“Through working closely with our clients and consortium partners, we were able
to develop this important project which builds upon recent exploration success
in the area. This project will support the upcoming bid round offshore Sarawak
and will spearhead the next wave of exploration in this region.”

TGS Announces Q2 2021 Results

OSLO, Norway (22 July 2021) - TGS today reported interim financial results for
Q2 2021.

…

Vis børsmeldingen

Net IFRS revenues amounted to USD 72 million in Q2 2021, an increase of 9%
compared to Q2 2020 and USD 7 million higher than the preliminary earnings
update July 8(th). EBITDA was USD 50 million, and the operating result was USD
-15 million, compared to USD 27 million and USD -97 million, respectively, in Q2
2020.

Net segment revenues (1) amounted to USD 54 million in Q2 2021, compared to USD
96 million in Q2 2020. Segment EBITDA was USD 32 million versus USD 56 million
in the same quarter of 2020, while the segment operating result amounted to USD
-25 million, compared to USD -85 million in Q2 2020.

Free-cash flow (2) amounted to USD 18 million in Q2 2021, up from USD -10
million in Q2 2020. After shareholder distribution of USD 20 million and
spending USD 24 million in relation to mergers & acquisitions, the cash balance
totaled USD 223 million at 30 June 2021.

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 14 million.

“Our asset-light business model, robust balance sheet and strong cash flow
enable us to take advantage of strategic opportunities, both in our subsurface
data business and in our New Energy Solutions segment. As described in previous
reports, the market conditions for multi-client seismic data continue to be very
challenging, and there are no signs of substantial improvements in the near-
term. However, based on dialogue with our largest customers, we remain confident
that we will ultimately see a recovery of the market,” says Kristian Johansen,
CEO of TGS.

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.

Adjustments between IFRS and Segment revenue numbers for Q2 2021:
IFRS reported revenue: USD 72 million

• Revenue recognized from performance obligations met during Q2 for completed
  projects: USD 43 million

• Revenue recognized under POC during Q1: USD 25 million
  = Net segment revenue reported revenue: USD 54 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.

2 - Defined as Cash flow from operations after organic investments in the multi-
client library.

TGS Announces NOAKA Ocean Bottom Node Seismic Survey on the Norwegian Continental Shelf

OSLO, Norway (2 August 2021) - TGS, a global provider of energy data and
intelligence, today announced a new Ocean Bottom Node (OBN) seismic survey on
the Norwegian Continental Shelf (NCS).
…

Vis børsmeldingen

The 437 square kilometer survey will be acquired in the NOAKA area, between
Oseberg and Alvheim in the Norwegian North Sea, containing both held and open
acreage. This region has seen significant Infrastructure-Led Exploration (ILX)
activity in recent years and includes the development of the NOAKA fields, one
of the largest developments on the NCS, with recoverable reserves of more than
500 million barrels of oil equivalents.

TGS expects to emulate the recent success of the TGS-AGS Utsira OBN project in
the North Sea (the first large-scale, densely sampled OBN survey for
exploration) and will apply the learnings from TGS’ ongoing reprocessing of
Utsira, including the extraction and use of ultra-long offset signal for FWI-
based model building. As with Utsira, the NOAKA survey will utilize full azimuth
and ultra-long offsets to understand and illuminate the complex geology in the
region. In addition, it will make use of multicomponent processing leading to
stable low frequencies, high signal-to-noise ratios, reliable AVO and the
ability to distinguish between structure and attribute anomalies.

Kristian Johansen, CEO at TGS, stated: “TGS remains committed to further advance
its position as a leading provider of OBN technology to the energy industry. We
continue to focus on areas, such as U.S. GOM and the North Sea, where the
enhanced insight from this method can generate economically attractive new
exploration opportunities for our clients”.

Acquisition is expected to commence in Q3 2021 with final processing
deliverables expected in Q3 2022. Revenues are expected to be recognized in Q4
2021.

TGS Vesting Under the 2018 Long-term Incentive Plan

In accordance with the measures approved by the shareholders of TGS at the
Annual General Meeting on 8 May 2018, the Board of Directors of TGS NOPEC
Geophysical Company ASA authorized TGS to grant Performance Stock Units (PSUs),
…

Vis børsmeldingen

Performance Restricted Stock Units (P-RSUs), and Restricted Stock Units (RSUs)
under the 2018 Long Term Incentive Plan to key employees of TGS on 3 August
2018. Each RSU represented the right to receive one share, while each PSU and
P-RSU represented the right to receive a maximum of one share depending on
performance against target metrics during the measurement period of 1 January
2018 to 31 December 2020. The granted PSUs, P-RSUs, and RSUs were secured by
free-standing warrants.

In accordance with the terms of the 2018 Long Term Incentive Plan, the PSUs, P-
RSUs, and RSUs vested on 3 August 2021, resulting in a total of 58 PSU/P-RSU/RSU
holders having the right to request the issuance of a total of 247,000 TGS
shares at par value NOK 0.25. The TGS Board of Directors determined that the
final payout on the PSUs and P-RSUs is 60% based on achievement of performance
metrics set forth in the plan, resulting in a total of 174,000 shares issuable
to ten holders of the vested PSUs and 16,800 shares issuable to four holders of
P-RSUs. In addition, 56,200 shares are issuable to 44 employees for the vesting
of the RSUs.

PSU/P-RSU/RSU holders have the option of allowing a portion of their vested
shares to be cash settled by TGS, using the fair market value of the shares as
defined under the plan, to cover tax withholding obligations and other necessary
deductions that arise in connection with the vest.

Correction: TGS Vesting Under the 2018 Long-term Incentive Plan

In accordance with the measures approved by the shareholders of TGS at the
Annual General Meeting on 8 May 2018, the Board of Directors of TGS ASA
authorized TGS to grant Performance Stock Units (PSUs), Performance Restricted
…

Vis børsmeldingen

Stock Units (P-RSUs), and Restricted Stock Units (RSUs) under the 2018 Long Term
Incentive Plan to key employees of TGS on 3 August 2018. Each RSU represented
the right to receive one share, while each PSU and P-RSU represented the right
to receive a maximum of one share depending on performance against target
metrics during the measurement period of 1 January 2018 to 31 December 2020.
The granted PSUs, P-RSUs, and RSUs were secured by free-standing warrants.

In accordance with the terms of the 2018 Long Term Incentive Plan, the PSUs, P-
RSUs, and RSUs vested on 3 August 2021, resulting in a total of 58 PSU/P-RSU/RSU
holders having the right to request the issuance of a total of 247,000 TGS
shares at par value NOK 0.25. The TGS Board of Directors determined that the
final payout on the PSUs and P-RSUs is 60% based on achievement of performance
metrics set forth in the plan, resulting in a total of 174,000 shares issuable
to ten holders of the vested PSUs and 16,800 shares issuable to four holders of
P-RSUs. In addition, 56,200 shares are issuable to 44 employees for the vesting
of the RSUs.

PSU/P-RSU/RSU holders have the option of allowing a portion of their vested
shares to be cash settled by TGS, using the fair market value of the shares as
defined under the plan, to cover tax withholding obligations and other necessary
deductions that arise in connection with the vest.

The following primary insiders have the right to request the issuance of the
following number of TGS shares related to the vesting of the PSUs/P-RSUs/RSUs, a
portion of which may be cash-settled as described above:

----Fredrik Amundsen – 15,000 shares

----William J.C. Ashby – 15,000 shares

----Whitney Eaton --­­ 1,000 shares

----Kristian Kuvaas Johansen – 40,800 shares

----Sven Borre Larsen ­-- 19,200 shares

----Tana LaDon Pool --­­ 15,000 shares

----Tanya Herwanger – 9,000 shares

----Amund Soia – 1,000 shares

----David Hajovsky – 4,200 shares

Attached is the list of primary insiders reflecting the balance of free-standing
warrants relating to granted PSUs, P-RSUs, and RSUs after the vesting of the
2018 Long Term Incentive Plan.

TGS Awards Performance Share Units and Restricted Share Units

Oslo, Norway (18 August 2021) - TGS ASA has issued awards of Performance Share
Units (PSUs) and Restricted Share Units (RSUs) to 89 key employees of the
Company, as authorized by the shareholders of the Company at its Annual General
…

Vis børsmeldingen

Meeting on 11 May 2021. The PSUs and RSUs are secured by free-standing warrants
that, upon vesting of the PSUs and RSUs in accordance with their terms, are
convertible to shares of the Company’s common stock. Each PSU represents the
right to receive the maximum of one share, while each RSU represents the right
to receive one share.

The PSUs are granted to members of the executive and senior leadership teams and
will vest on 10 August 2024, provided the employee remains employed with TGS on
the vesting date. Upon vesting, the PSUs will be converted to TGS shares on the
terms approved by the Annual General Meeting, depending on performance versus
target metrics. The number of shares will be determined by multiplying the
number of PSUs granted by a factor of 0% to 100%. The factor is determined by
performance against three target metrics: (i) relative return on average capital
employed compared against a defined peer group of companies, (ii) TGS’ return on
average capital employed, and (iii) HSE and ESG goals. Each of the performance
metrics is measured for the period 1 January 2021 through 31 December 2023.

The RSUs are granted to certain key employees and will also vest on 10 August
2024, provided the employee remains employed at vesting and has achieved a
satisfactory performance rating against their goals over the three-year plan
period. Upon vesting, the holder of the RSUs will receive an equivalent number
of TGS shares.

The list of the primary insiders receiving PSUs and RSUs is attached. The
maximum number of new shares to be issued under the awarded PSUs and RSUs is
550,000.
