- Going concern
- Affirmed
“The directors have completed an assessment of business and liquidity risks and an assessment of forecast future results and the Company has received a letter of support from Lummus Technology Holdings V LLC confirming that it will provide support to the Company should it be required for a period of at least twelve months from the date of approval of these financial statements. The directors have therefore concluded that the Company has adequate resources to continue in operational existence for a period of a year from the date of approval of these financial statements.”
Significant events
- “The war in Ukraine and conflict between Iran and Israel has led to material fluctuations in oil and natural gas prices, with energy security and affordability back at the top of the agenda. This may result in a long term policy push towards renewables, alternative energy sources, carbon abatement and energy efficiency. This will continue to be the growing trend/direction of the energy sector. Our business is progressively adapting to support our clients' evolving needs.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
