Net cash flow from operating activities resulted in a surplus of euro 2,048 million in 2023, compared with a surplus of euro 2,417 million in 2022. The main change is related to the income tax paid, which amounts to euro 669 million in 2023 compared to euro 430 million in the previous year. This increase is partially related to the payment made by the Groupe in January 2023 of an additional euro 107 million in respect of the 2022 financial year, reflecting the implementation of the "Tax Cuts and Jobs Act" (TCJA) in the United States. This tax legislation requires the capitalization and amortization of R&D expenses in the United States over five years.

The loan repayments amounted to euro 502 million in 2023 (mainly related to the Eurobond 2023 in November), compared with euro 10 million in 2022. The (net) repurchase of treasury shares generated a cash outflow of euro 189 million (compared with a cash inflow of euro 41 million in 2022), mainly linked to the share buyback program related to 3,000,000 treasury shares, which took place in February and March for a total amount of euro 222 million.
