Going concern

Affirmed

“After making enquiries and having taken into consideration the above factors, the Directors have reasonable expectation that the Company has adequate resources to continue in operational existence for the going concern period. Accordingly, they continue to adopt the going concern basis in preparing the financial statements.”

Significant events

• “The Triton Hub experienced a mixed 2024 - where positive subsurface results were achieved from infill well drilling, but production was disappointing due to a number of unplanned outages that resulted in a year-on-year average production decline from 14,100 boepd to 9,000 boepd.”
• “The first shutdown in May followed a trip on the single gas export compressor that was available, a weakness that continued throughout 2024, causing another significant outage in Q4 commencing from 26 October. Production was also adversely impacted by the summer shutdown for annual maintenance work on Triton overrunning by three weeks..”
• “Unfortunately, problems have continued into the start of 2025, as issues resulting from Storm Éowyn caused production to be suspended at the end of January.”
• “In May 2024, the Company's sister company Serica Energy (UK) Limited transferred its 50% owned and operated Columbus field to the Company for a consideration of $15.1 million. The Company now owns a 75% equity interest in the Columbus field.”
• “In July 2024, the Company's sister company Serica Energy (UK) Limited also transferred its 18% owned non-operated Erskine field to the Company for a consideration of $0.5 million.”
• “In the prior year, on 1 September 2023, the Company transferred its 100% owned and operated oil and gas assets which included the Gannet E, Evelyn and a share of the Triton FPSO to its sister company, Serica Energy Chinook Limited for a consideration of $153.0 million.”

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
