5 CONSOLIDATED FINANCIAL STATEMENTS AT DECEMBER 31, 2021 Consolidated financial statements and notes

In accordance with Delegated Regulation No. 2015/63 and Implementing Regulation No. 2015/81 supplementing the BRRD Directive on ex-ante contributions to financing mechanisms for the resolution, the Single Resolution Board set the level of contributions to the Single Resolution Fund for 2021. Contributions paid to the fund may be made in cash security deposits recognized as assets on the balance sheet (15% in cash security deposits) and in contributions recorded in income as “Taxes and regulatory contributions” (see Note 6.7) . 5.22 In preparing its financial statements, Natixis is required to make certain estimates and assumptions based on available information which are likely to require expert judgment. This exercise has been made particularly difficult given the current health crisis, which has had unprecedented repercussions on the global economy. These estimates and assumptions constitute sources of uncertainty which may affect the calculation of income and expenses in the income statement, the value of assets and liabilities in the balance sheet and/or certain disclosures in the notes to the financial statements. Thus, the future results of certain transactions could prove to be significantly different from the estimates used to close the financial statements on December 31, 2021, particularly in the current circumstances of extreme uncertainty. Accounting estimates requiring assumptions to be made are mainly used to measure the items set out below: Financial instruments recorded at fair value The fair value of hybrid market instruments not traded on an active market is calculated using valuation techniques. Valuations produced using valuation models are adjusted, depending on the instruments in question and the associated risks, to take account of the bid and ask price for the net position, modeling risks, assumptions regarding the funding cost of future cash flows from uncollateralized or imperfectly collateralized derivatives, as well as counterparty and input risks. The fair values obtained from these methods may differ from the actual prices at which such transactions might be executed in the event of a sale on the market. The valuation models used to price illiquid financial instruments are described in Note 7.5. Some of the unlisted equity instruments categorized under IFRS 9 as “Financial assets at fair value through profit or loss” or “Financial assets at fair value through non-recyclable other comprehensive income” consist of investments in non-consolidated companies. The fair value of investments in unlisted non-consolidated companies is obtained principally by using valuation methods based on multiples or DCF (discounted cash flow). Use of these methods requires certain choices and assumptions to be made in advance, including projected future cash flow forecasts and discount rates. Impairments for expected credit losses The impairment model for expected credit losses is based on parameters and assumptions that affect provisions and value adjustments for losses. These parameters and assumptions are based on current and/or historical data, which also include reasonable and justifiable forecasts such as the estimating and weighting of future economic scenarios. Natixis also considers the opinions of its experts when estimating and applying these parameters and assumptions. Use of estimates and judgment

Guarantee commitments received There are no IFRS standards covering financial guarantees received (other than derivatives or insurance contracts). In the absence of specific guidance, the accounting treatment applied must be determined by analogy with the accounting treatment prescribed by other standards in similar situations. Accordingly, guarantees received meeting the definition of a financial guarantee for an issuer are accounted for in accordance with: IFRS 9, for guarantees received in respect of financial assets (debt V instruments). The measurement of the expected credit losses associated with financial assets must in fact take into account the flows generated by guarantees considered an integral part of the debt instrument; IAS 37, for guarantees received in respect of non-financial liabilities V falling within the scope of IAS 37. b) Financing commitments Financing commitments are irrevocable commitments by Natixis to grant a loan under pre-defined conditions. The vast majority of the financing commitments granted by Natixis give rise to loans granted at market rates at the grant date and recognized at amortized cost. As such, and in accordance with IFRS 9, the commitment to lend and the loan itself are considered successive stages of one and the same instrument. The commitment to lend does not, therefore, fall within the scope of IFRS 9: it is treated as an off-balance sheet transaction and is not revalued. Financing commitments are eligible for the provisioning mechanism under IFRS 9, however (see Note 5.3) . IFRS 9 provides that the issuer of a financing commitment must apply provisioning criteria to loan commitments that do not fall within the scope of this standard. The provisions recognized in respect of these commitments are presented in Note 7.17 “Summary of provisions”. resolution mechanisms The procedure for setting up the deposit and resolution guarantee fund was changed by a French Ministerial Order dated October 27, 2015. Contributions made to the deposit and resolution guarantee fund may be paid in the form of partner or association certificates and cash security deposits (guarantee of irrevocable commitment) recognized as assets on the balance sheet and contributions (which are non-refundable in the event of a voluntary withdrawal of approval to operate) recorded in income as “Taxes and regulatory contributions” among other operating expenses (see Note 6.7) . Directive 2014/59/EU (BRRD – Bank Recovery and Resolution Directive) which establishes the framework for the recovery and resolution of banks and investment firms and Regulation (EU) 806/2014 (SRM regulation) established the introduction of a resolution fund as of 2015. In 2016, this fund became a Single Resolution Fund (SRF) between the member States participating in the Single Supervisory Mechanism (SSM). The SRF is a resolution financing mechanism available to the resolution authority (Single Resolution Board). The latter may use this fund when implementing resolution procedures.
