Moody’s Sustainability Assessment
Meridiam monitors its CSR performance every two years based on an assessment conducted by a third-party ESG/SDG ratings agency – Moody’s. Since 2020, this assessment is even more comprehensive and covers the whole sustainability approach of Meridiam and how it is implemented in all its activities.

The Sustainability Assessment was first carried out in 2020 and again in 2022 on Meridiam and its portfolios, and covered SDG-orientated topics. In the 2022 Sustainability Assessment, Meridiam obtained a scoring of 65/100, hence rating “Advanced”*, as was the case in 2020 (see Advanced Sustainability Rating by Moody’s).

[*] Recognition was received in December 2022. Members of Moody’s ESG Solutions are required to pay for their application to be analyzed and scored against Moody’s benchmarks.

A new era for SIMPL.

In November 2021, Meridiam was ISO 37001 certified by the French Association for Standardization (AFNOR) (see certificate). As a reminder, this standard assesses the reliability and performance of anti-corruption management systems within various organizations.

Initially covering the Paris headquarters and two of its African offices (Dakar and Addis Ababa), this certification was extended two years later, in 2023, to the offices in Libreville (Gabon) and Johannesburg (South Africa). In November 2025, it was further extended to all European offices.

The fight against corruption at all levels (investors, partners, suppliers, employees) and all geographies is a priority for Meridiam.
