Andrew HockeyCEO of IOG, commented:

“Last year saw an immense effort by the whole IOG team to progress towards production, culminating in the safe and successful delivery of First Gas from the Blythe and Elgood fields on 13 and March 15, 2022 respectively. I am very proud of our team for overcoming the many challenges we’ve faced and achieving this major milestone. By working closely together, guided by our core values ​​of resourcefulness, innovation, drive, efficiency, resilience and safety, we have turned IOG from an unfunded micro-cap into a material UK gas producer with exciting further growth plans.

We can now start to reap the benefits of our strategic focus on UK gas, which has always had compelling economic logic: the UK remains highly dependent on this commodity that will be pivotal in the global energy transition. Phase 1 production gives IOG both the operational platform and the financial capacity to deliver incremental value for our shareholders.

I believe we have the right people, assets and partnerships to build on what we have achieved so far and deliver exciting further phases of growth over the years ahead: what I call our “project factory”. I would like to thank the whole team, our partner CER and all our contractors for their dedication in making Phase 1 production a reality. I also owe all our shareholders my sincere thanks for their continued support in helping us turn IOG, your company, into a respected UK gas developer and producer. I believe this is just the start and I look forward to delivering further growth on your behalf.”
