SDCL Efficiency Income Trust plc ("SEIT" or the "Company")
Project Finance Agreement to reduce RCF

SDCL Efficiency Income Trust plc (LSE: SEIT) is pleased to announce a new financing facility. This has been negotiated on favourable terms and serves to achieve liquidity that will be used to reduce SEIT's drawings on its RCF by approximately £17 million.

Financing at Zood Infrastructure Ltd ("Zood")

As referred to in the Annual Results on 23 June 2025, Sustainable Development Capital LLP ("SDCL" or the "Investment Manager") has successfully secured a new senior debt facility for the Zood portfolio of operational assets, operated and managed by the Electric Vehicle Network ("EVN"). Zood is wholly owned by SEIT, which also owns a 15% minority stake in EVN. The new financing does not prevent a full or partial disposal in the future.

The facility provides an initial £17.6 million in long-term financing plus an additional uncommitted facility of up to £40 million to support Zood's growing pipeline of projects. The majority of the initial drawing will be used to reduce the Company's RCF,

Jonathan Maxwell, CEO of SDCL, commented:

"As we focus on de-leveraging SEIT and crystallising value for its shareholders, the financing at Zood helps to reduce SEIT's short term revolving credit facility, while providing Zood with financing.

"The Investment Manager is targeting disposals and refinancings in the coming months with the objective to continue to reduce the RCF and, ultimately, to return capital to shareholders."
