(2) The statistics include only active seismic 3D vessels (capacity working on

New Energy Solutions projects are excluded). The Ramform Victory was brought

into operation in Q3 2023, and the Ramform Vanguard was converted to a dual-

purpose seismic and offshore wind vessel in Q2 2024. The two cold-stacked

vessels are excluded from the statistics.)

Based on a preliminary financial review TGS expects organic Q4 2024 multi-client

investment to be approximately USD 100 million.

Kristian Johansen, CEO at TGS, commented: "Utilization of our OBN crews in Q4

was strong, with most of the activity focused on acquiring 4D production data in

the US Gulf of Mexico. Project delays from late 2024 and into 2025 caused our

multi-client investment to be in the low-end of the guided range, which also

impacted vessel utilization in the quarter. I'm pleased about solid multi-client

performance in Q4, and for the full year 2024. During the quarter we announced

four significant streamer contract awards, enhancing visibility and vessel

utilization for the first half of 2025."

TGS will release its Q4 2024 results at 07:00 a.m. CET on 20 February 2025. CEO

Kristian Johansen and CFO Sven Børre Larsen will present the results at 09:00

a.m. CET during a live presentation and webcast. The presentation will take

place at House of Oslo, Ruseløkkveien 34, 0251 Oslo and is open to the public.
