Hello, and thank you for taking an interest in our news flow. Today, we are delighted to announce and present the details of our latest acquisition. This transaction has added significance, given it represents a major step into a new target market of renewable energy, and of course, it's our first international venture. Turning to slide two of the deck, Full Circle are an established brand in the onshore wind turbine services market, headquartered in Amersfoort, Holland, providing operational field services across the U.K. and selected European territories. The acquisition represents an excellent fit with our proven M&A criteria, namely, Full Circle have long-term client relationships, highly recurring, full-scope contracts, directly delivered monitoring, repair, and maintenance services, a market with high barriers to new entrants, a very experienced management team, and importantly, reliable and accretive operating margins.
We have purposefully targeted specific renewables market, given the tremendous growth prospects and the fact that opportunities are emerging as site owners consider alternative service options as OEM arrangements come to the end of their life. In terms of value and deal structure, Sean?
Sure. We are paying EUR 60 million for Full Circle, which represents 10x EBITDA, based on our expectations for the business for the 12 months to September 2025, which, of course, is our financial year 2025. The transaction is being funded out of existing cash resources and our RCF, which has been increased to GBP 120 million from GBP 80 million, which will give us firepower for further acquisitions. The acquisition will be immediately earnings enhancing and will have ROIC in excess of our cost of capital within three full years of ownership.
Turning to slide 3, here are illustrations of the tremendous long-term and reliable growth opportunities in a market with numerous tailwinds, including binding commitments in the U.K. and across Europe for an energy transition, as we target and move towards net zero. Wind energy is fundamental to everybody's plans in this regard. Over the next five years, as the chart on the right indicates, the market for onshore O&M wind services is forecast to double, and the chart on the left of this page sets out the plans for onshore wind energy capacity increases across each of the territories where Full Circle have established an operational presence, noting on this chart an 8% compound annual growth rate through to 2030. Extremely reliable indeed.
A related attraction is the fact that Full Circle are already very strong in the U.K., and they are selectively seeding and growing a presence in targeted European territories. Turning to slide 4, this is a picture of the competitor landscape in the territories where Full Circle are currently focused. So you'll see it's a very fragmented situation in the four larger territories where it operates, and they screen very strongly in terms of capability, range, and scale. They are the only pure-play, full-scope, independent service provider of onshore wind services. Turning to slide 5, well, it's here that we set out Full Circle's full-scope service proposition. Their control center in Amersfoort has 24/7 state-of-the-art remote monitoring capability, including a differentiated ability for continuous predictive maintenance, which can dramatically improve operational availability.
Service responsibilities also include aspects of remote real-time monitoring and control, diagnostic, advice, service and maintenance, including event response, blade repair, you can actually see a drone inspecting some blades on one of the images at the bottom of this, page, and major component replacement. Operational availability rates for turbines under Full Circle management are typically, around 97%. Turning to slide six, Sean.
Yep. Full Circle has excellent revenue visibility through its long-term O&M contracts, which can vary between three and 15 years in duration and have a 95% renewal rate on existing contracts once the initial term ends. The business has successfully switched its focus from only servicing EWT turbines into a multi-brand strategy, which has grown from less than EUR 5 million in FY 2021 to a forecast of EUR 10 million in the twelve months to September 2025. This has supported the revenue growth in the business from GBP 22 million in FY 2023 to a forecast of GBP 31 million in the twelve months to September 2025, with a sustainable operating profit margin of 14%, which, of course, is higher than the existing group margin and is therefore accretive.
While the business is based in the Netherlands, approximately 78% of its revenue is derived in the U.K., with the rest split between France, Italy, Greece, and the Netherlands.
In summarizing, we are delighted to have acquired a leading brand in a new and compelling market sector. The growth potential is tremendous, given the tailwinds for onshore wind. We see opportunities to further leverage full-scope services in both existing and new territories. The well-established relationship servicing EWT turbines, as well as a growing list of multi-brand contracts, presents an extremely reliable pipeline. We've acquired a very experienced management team, who have ambition to build on the established platform through both organic and inorganic expansion, and of course, we will leverage the wider capabilities of Renew's engineering expertise and scale to support these growth ambitions.
