(1) Including 27 million euros in accretion and changes in discount and inflation rates recognized in net fi nancial income (expense) (see Note 7).

Provisions for onerous contracts In the Mining Business, updated cost assumptions led to the recognition of a provision for onerous contracts of 15 million euros. Provisions for work yet to be carried out The main provisions allocated for the fi nancial year relate to the future costs of processing and storing waste and scrap. The main reversals during the fi nancial year relate to the expenses incurred for the treatment and storage of previously provisioned waste and scrap. Main uncertainties Uncertainties relating to provisions for contract completion bear notably on the de fi nition of treatment channels for each category of waste and operating discharges, which are not all fi rmly established, the estimate of the cost of completion of the required facilities and the operational costs of future treatment, and on expenditure schedules. The measurement of provisions takes contingencies for risks into account.

Discount rate At December 31, 2025, Orano assumed discount rates of between 4.85% and 5.08% and a long-term inflation rate of between 1.99% and 2.01%. At December 31, 2024, Orano assumed discount rates of between 4.41% and 4.84% and a long-term inflation rate between 1.85% and 1.89%. At December 31, 2025, the use of an actual discount rate of 10 basis points higher or lower than that used would change the closing balance of provisions for contract completion by -21 million euros or +21 million euros. Other current and non-current provisions At December 31, 2025, other current provisions include in particular: ● provisions for disputes;

● provisions for business contingencies; ● provisions for customer guarantees; ● provisions for ongoing clean-up;

● provisions for the remediation of leased assets; ● provisions for restructuring and layoff plans; ● provisions for contingencies; and ● provisions for losses.
