Oslo, Norway (9 September 2024) - In February 2019, TGS implemented an

purchase TGS common shares at a discount through payroll deductions. The ESPP
operates in six-month periods, and at the end of each period, employees in
eligible jurisdictions (United States, United Kingdom and Canada) have the
option to purchase stock at a 15% discount to the market price at the time of
purchase.  The plan sets a maximum purchase of shares per employee per six-month
period and ESPP dividends are reinvested in shares.

The following primary insiders received shares from the ESPP purchase on
September 5, 2024, as participants in the ESPP.  The schedule attached reflects
