Based on preliminary reporting from operating units, management of TGS expects Produced revenues³ to be approximately USD 400 million in Q2 2026, versus a company collected consensus estimate of USD 359 million. Produced revenues in Q2 2025 were USD 308 million. Multi-client investment is expected to be approximately USD 168 million in Q2 2026, compared to USD 114 million in Q2 2025.

Kristian Johansen, CEO of TGS commented: “I am very pleased to report strong Q2 revenues with a Y/Y growth of 30%, driven primarily by solid multi-client performance in Latin America and Africa. Asset utilization during the quarter was slightly above our expectations, with 3D streamer utilization reaching 94% and an average normalized OBN crew count of 1.7. While the de-escalation of the conflict in the Middle East has resulted in lower oil prices, the oil companies are gradually becoming more focused on replenishing reserves through exploration. Supported by increasing energy security requirements and the need to sustain long-term production, we remain confident that exploration activity is set to grow over the coming years.”

TGS will release its Q2 2026 results at 07:00 a.m. CEST on 23 July 2026. CEO Kristian Johansen and CFO Sven Børre Larsen will present the results at 09:00 a.m. CEST, webcasted live.

^{³ For the purpose of Produced revenues, multi-client revenues committed prior to completion of projects are recognized on a percentage of completion basis. This differs from IFRS reporting, where revenues committed prior to completion are recognized when the customers receive access to the finished data. Management of TGS expects IFRS revenues to be approximately USD 373 million in Q2 2026, compared to USD 334.2 million in Q2 2025.}
