Regulatory provisions and applicable professional doctrine Our work described below was carried out in accordance with the professional guidelines of the Compagnie Nationale des Commissaires aux Comptes and the international standard ISAE 3000 (revised) " Assurance Engagements other than Audits and Reviews of Historical Financial Information " from the IAASB ( International Auditing and Assurance Standards Board ). Our independence is defined in the provisions of Article L.822-11 of the French Commercial Code and in our Code of Ethics. In addition, we have put in place a quality control system that includes documented policies and procedures to ensure compliance with applicable legal and regulatory texts, ethical rules and the professional doctrine of the Compagnienationale des commissaires aux comptes with respect to this intervention. Nature and scope of the work We have planned and performed our work in order to enable us to formulate a conclusion of moderate assurance on the following information (the “Information”): RES financing - amounts arranged in 2021 V Natixis Assurance general fund temperature at end 2021 V Percentage of Natixis Investment Managers assets under V Independence and quality control

The nature, timing and extent of the procedures performed on this information depend on our professional judgment, including the evaluation of the risks of material misstatement,whether they result from fraud or error. We took into account the relevant internal controls for the preparation of the Information by the Company during our risk assessment. We also have: assessed the appropriatenessof the Guidelineswith regard to their V relevance, completeness, reliability, neutrality and comprehensibility; verified the implementation of a process for the collection, V compilation, processing and control aimed at ensuring the completeness and consistency of the Information; conducted interviews with the relevant departments at the V Company’shead office and with a selection of contributingentities in order to analyze the deployment and application of the Guidelines; implementedanalytical procedures to verify the calculationsmade V and the correct consolidation of the data collected and the consistency of their changes; conducted detailed tests on the basis of sampling, carried out at V the level of a selection of representative (1) entities that we have selected, consisting of verifying the correct application of definitions and procedures and reconciling the data with the supporting documents. The sample thus selected covers between 74% and 100% of the consolidated data relating to Information. We believe that the audit evidencewe have obtained is sufficient and appropriate to provide a basis for our opinion. The procedures implemented as part of a moderate assurance are less extensive than those required for a reasonable assurance carried out in accordance with the professional doctrine of the Compagnie Nationale des Commissaires aux Comptes; a higher level of assurance would have required more extensive audit work.
