Innovation was a key driver of our growth as launches already contributed 11 percent of sales, with Beyfortus becoming a blockbuster in its first full year of sales. We exceeded our business EPS guidance. In 2024, we announced an intention to sell a controlling stake in Opella consumer health, which will make Sanofi a focused, science-driven biopharma company. We increased R&D investments and achieved significant progress with our pipeline in 2024, including positive phase 3 study results for new medicines such as rilzabrutinib in rare diseases and tolebrutinib in multiple sclerosis. As we enter 2025, we expect continued, solid growth in sales and a strong rebound in earnings. We are also confident in the mid to long-term growth prospects of Sanofi, supported by ongoing launches, Dupixent (currently expected to reach sales of around €22 billion in 2030 7 , in line with the current ambition), and expected future launches from our pipeline.” Q4 2024 Change Change at CER FY 2024 Change Change at CER IFRS net sales reported €10,564m +9.1% +10.3% €41,081m +8.6% +11.3% IFRS net income reported €683m — — €5,744m +6.4% — IFRS EPS reported €0.54 — — €4.59 +6.5% — Free cash flow 8 €2,340m -25.5% — €5,955m -19.6% — Business operating income €2,078m -11.8% -7.7 % €11,343m +1.5% +7.6% Business net income €1,642m -15.1% -11.2 % €8,912m -1.8% +4.1% Business EPS €1.31 -14.9% -11.0% €7.12 -1.8% +4.1% 1 Changes in net sales are at constant exchange rates (CER) unless stated otherwise (definition in Appendix 9). 2 To facilitate an understanding of operational performance, Sanofi comments on the business net income statement which is a non-IFRS financial measure (definition in Appendix 9).
