The new funding will enable Mainstream to deliver on its updated and more focused strategy, concentrating on developing its pipeline of projects primarily in three core markets where it sees the greatest potential for value creation - South Africa, Australia, and the Philippines - and creating value through strong project execution, a lean cost base and capital efficiency.

In 2023, Mainstream secured a corporate facility of up to USD 220 million with DNB, supported by shareholders. Aker Horizons' share of the sponsor commitment is 58.4% of the maximum facility size, equivalent to USD 129 million. This amount will be provided to Mainstream as a shareholder loan, disbursed in phases: USD 75 million will be provided in April 2025, while the remaining USD 53 million will initially be provided through an extended letter of credit facility expected to be converted to shareholder loans in 2025 and 2026.

Additionally, new funding for Mainstream has been agreed upon in the form of a shareholder loan facility of up to EUR 64 million provided pro-rata 70% by Aker Horizons and 30% by Mitsui, along with a letter of credit facility with DNB of up to EUR 64 million, also backed pro-rata by Aker Horizons and Mitsui. Both facilities may be drawn until maturity at year-end 2026, with drawdowns contingent on reaching agreed milestones under Mainstream's updated strategy.
