The gain on existing interest in 2024 resulted from the revaluation of the investment in Prosino S.r.l. (Borgosesia, Italy) at fair value due to the increased interest in voting rights (see note 2.1 and 6.3).

Miscellaneous other income includes income that is not presented as sales, such as income from export incentive schemes and income from government grants. In 2024, this also includes a portion of the insurance compensation received for the earthquake in Türkiye in 2023 and the release of the environmental provision relating to the sold land and buildings in Ingolstadt (Germany) (see note 4.8).

Miscellaneous other expenses include expenses that are not directly linked to cost of sales, or which cannot be allocated to research and development expenses or selling, general, and administrative expenses. Such expenses include costs related to cancelled customer projects and losses from onerous customer contracts.
