INPP reaches Finacial Close on Sizewell C4 Nov 2025 13:38
All conditions to financial close have now been satisfied, marking the start of revenue commencement. Under the RAB model, INPP will benefit from regulated, inflation-linked returns from day one of its investment, as returns are not exposed to fluctuations in power generation or the market price. Through the construction and early operations phase to the late 2030s, the investment offers a fixed, regulated equity return of 10.8% in real terms, including an annual cash yield of c.6%, resulting in a forecast internal rate of return ('IRR') in the low-teens, well above the returns achievable through share buybacks. These returns are subject to Ofgem's licence and underpinned by a Government Support Package that provides protections in the event of construction cost overruns or delays and ring-fences nuclear-specific risks, consistent with INPP's prior disclosures[2].
