- Affirmed
“Management has produced forecasts to reflect plausible scenarios that consider the sector environment as a whole. During the entire pandemic the company remained cash positive, despite significant headwinds. The company has recovered strongly from the pandemic downturn with significant growth and very strong cash generation, and would remain cash positive, even without forecast growth. These forecasts, coupled with the assessment of the company's financial position give the company's directors a reasonable expectation that the company will be able to continue in operational existence for the foreseeable future. Thus management continue to adopt the going concern basis of accounting in preparing the annual financial statements.”
Significant events
- “In September 2022, the company as an entity was acquired from ION Geophysical Corporation by Sercel Holding SAS (Sercel), a company registered in France.”
- “During 2024, the company continued with strong integration with Sercel and Viridien, against a background of sustained market improvement post pandemic.”
- “Looking ahead, the directors believe we are now in a favourable multiyear upcycle, driven by years of underinvestment and lack of supply of oil and gas. As such, exploration will increase, especially offshore, to fill the supply gap.”
- “geopolitical events have continued to place a different emphasis on the energy industry and energy security that may increase sector spend in due course. The company also has a strategy to diversify to non-energy sectors, this is beginning to gain traction, and progress is being made in new markets.”
