• Allowed WACCs/RoE are usually adjusted only once per regulatory period Short-term • Inflation-indexation in most countries with t+2 time-lag

• Allowed WACCs/RoE to gradually increase (with start of new regulatory periods) Mid-term due to higher interest rates • Positive effect from inflation-indexation (double digit million effect p.a.)

• Higher allowed WACCs/RoE with start of new regulatory periods in all countries Sensitivities Long-term • Allowed WACCs/RoE : +1% in regulatory return rate leads to triple digit million Euro increase of allowed returns p.a. • Inflation-indexation: +1% in inflation leads to a high double digit million Euro increase p.a.

Prior-year figures have been adjusted due to the subsequent adjustment of certain figures. 3. From 2019 onward, emissions from power and heat generation are divided into emissions from plants owned and operated by E.ON (Scope 1) and emissions from plants leased to, and operated by, customers (Scope 3). 4. The Greenhouse Gas Protocol and DEFRA attribute no direct CO2 emissions to energy generated at renewable facilities and nuclear power stations. This figure includes emissions from power and heat generation from CHP assets leased to B2B customers since 2018. 5.
