1) 2. Are single applicants eligible to apply, or is this call meant for consortia only?

For the PRIMARY Open Call, only consortia of 2-3 partners can apply. Single

applicants are not eligible. Consortia with more than 3 entities will be rejected during

the eligibility criteria evaluation phase.

2) 3. How many applications can one (1) entity submit? And how many of them can be selected for funding?

Applicants can participate in only one (1) consortium and participate in the call with

only one (1) proposal. If multiple versions of the same application are submitted, only

the last version will be evaluated.

3) 4. Can entities from non-EU countries submit proposals to the PRIMARY Open Call?

Applicants from non-EU countries may apply if they are eligible under the Horizon

Europe Regulation 2021/695 and the List of Participating Countries (Horizon Europe:

V3.8 – 12.02.2026) and are explicitly included in the list of eligible countries provided

in Section 2.2.3 of the PRIMARY Open Call Applicants’ Guide. Applicants from countries not included in this list are not eligible to participate in the PRIMARY Open

Call.

4) 5. Can successful applicants receive payment in advance after contracting?

In all selected sub-projects, payments are deliverable-based, meaning that the sub￾grantees need to deliver a specific report after the end of each phase to receive the payment (no prefinancing is foreseen). First payment will take place after the

submission and evaluation of the first deliverable in M04.

5) 6. For how long will the platform accept proposals?

The platform will open for proposal submission on the 9th of March 2026, and it will

remain open until 17:00 CEST on the 8th of June 2026.
