Developing a phasing out strategy is a legal obligation under the Horizon Europe Regulation. When assessing the performance of partnerships funded under Horizon Europe, the absence of a credible phasing out strategy constitutes noncompliance with one of the implementation criteria set out in the legal framework (annex III). Such noncompliance will be reflected accordingly in monitoring and evaluation exercises, and may be (pending the final legislative framework that will be adopted) considered in the future selection of partnerships under FP10 (e.g. as part of the legacy criterion under the proposal for a Specific Programme implementing Horizon Europe 2028-2034).
