Successful Realisation of Investment in Streamline Innovations

Riverstone Credit Opportunities Income ("RCOI" or the "Company"), the LSE-listed energy infrastructure and energy-transition credit investor, is pleased to announce the successful realisation of its first lien green loan in Streamline Innovations (or "Streamline") at a 20 percent gross IRR (15 percent net IRR) and 1.33x gross MOIC (1.25x net MOIC).

In July 2023, RCOI committed $9.9 million in a first lien green loan to Streamline, a leader in environmentally-advanced treatment solutions for the removal of hydrogen sulfide (H2S) from energy, renewable fuels, wastewater, and industrial processes. This investment followed the successful realisation of RCOI's initial November 2021 investment in Streamline, in which RCOI committed $13.8 million in a first lien green loan and achieved a 24 percent gross IRR (19 percent net IRR) and a 1.3x gross MOIC (1.2x net MOIC).

The Company remains focused on the realisation of RCOI's assets and returning capital to shareholders. Since the Company's AGM on 22 May 2024 and adoption of the Wind-down Investment Policy, the Company has redeemed approximately 41 per cent of the Company's Ordinary Shares with 49,066,161 Ordinary Shares outstanding following the most recent redemption on 27 June 2025. Following this Realisation, the Company's portfolio is comprised of six remaining positions. Furthermore, the Company has an estimated unencumbered cash and cash equivalents position of approximately $4.8 million.
