TGS Awards Performance Share Units and Restricted Share Units

TGS Awards Performance Share Units and Restricted Share Units

Oslo, Norway (15 August 2025) - TGS has issued awards of Performance Share Units

(PSUs) and Restricted Share Units (RSUs) to 283 key employees of the Company, as

authorized by the shareholders of the company at its Annual General Meeting on

8 May 2025.  With the exception of certain PSUs and RSUs, which may be secured

by the Company's treasury stock, 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 a maximum of 1.5 shares, 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 15 August 2028, provided the employee remains employed with TGS on the

vesting date.  Upon vesting, the PSUs will be converted to the right to receive

TGS shares on the terms approved by the Annual General Meeting, depending on

performance versus target metrics.  The number of shares issuable upon vesting

will be determined by multiplying the number of PSUs granted by a factor of 0%

to 150%.  The factor is determined by performance against three target metrics:

(i) Absolute Total Shareholder Return (TSR), (ii) Relative TSR, and (iii) HSE

and Sustainability goals.  TSR performance is measured by the three-year period

commencing on the Date of Grant and ending on the Vesting Date.  HSE and

Sustainability performance is measured for the period 1 January 2025 through 31

December 2027.

The RSUs are granted to executives, senior leadership teams and other certain

key employees and will also vest on 15 August 2028, 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

1,900,000.
