Ithaca Energy, a leading UK independent production and growth company, today provides the following unaudited trading update for the year ended 31 December 2025.

Yaniv Friedman, Executive Chairman, commented: “2025 was a year of great progress as we continued to deliver on our value creation strategy. We fully integrated a number of accretive acquisitions, increased our financial firepower for growth and built on our robust hedge book to secure future investments and distributions. We also delivered meaningful increases in production, revenue and EBITDAX whilst reducing costs, all of which drove increased free cashflow, supporting our $500 million dividend commitment. We’re excited by our prospects for the year ahead and beyond, and we enter the year with a significantly increased production rate.”

Operational Highlights:

• Strong 2025 production: Average production of 119 kboe/d (2024: 80 kboe/d) in-line with previously upgraded guidance of 119-125 kboe/d and notwithstanding unprecedented levels of turnaround activity in the year
• Entering 2026 with increased installed production capacity: 2025 exit rate of approximately 148 kboe/d achieved, with a peak daily production exceeding 150 kboe/d in the period following delivery of new wells at Cygnus, Seagull and J Area
• Safe and responsible operator with ‘perfect day’ strategy driving positive trend in HSE performance: Zero Tier 1 or Tier 2 events recorded in the year and improved HSE performance with a material reduction in Total Recordable Injury Rate and in Greenhouse Gas emission intensity from 2024
• Material resource base: Preliminary 2P Reserves of over 350 mmboe and 2C Resources of over 300 mmboe as at 31 December 2025 (2024 2P Reserves and 2C Resources: 657 mmboe). Reserve/resource replacement delivered through material organic and inorganic investment across key growth areas with 2P reserves replacement ratio of over 130%

• Hedge position provides strong coverage into 2026: Material hedge book at year end 2025, with further proactive hedging through Q1, taking advantage of upside market volatility, to build a strong hedge position at 31 January of 43.8 mmboe (c.58% oil, c.42% gas) into 2027, with average oil swap pricing >$66/bbl and average gas swap pricing of 92p/therm, protecting 2026 cash flows in an anticipated weaker commodity price environment
• Financial firepower to support continued growth: Low leverage position of 0.56x with significant available liquidity of $1.5 billion at 31 December 2025, including $1.3bn fully undrawn Reserve Based Lending facility, which underpins capital allocation flexibility to continue to execute on our value creation strategy

• Targeted investment to support growth: Estimated 2025 net producing asset capital cost of $629 million at lower end of guidance of $630-670 million reflecting targeted organic investment in high return wells, reliability enhancement and efficiency opportunities supporting increased production capacity
• Significant progression of West of Shetlands Strategy: Estimated 2025 net Rosebank capital spend of $224 million, falling below the bottom end of guidance of $230-270 million, with critical milestone of FPSO sail away expected in Q1, supporting progression of the project towards first production.
