>If there is a withdrawal agreement, UK recipients will receive EU funding for projects agreed in the current funding cycle from the EU Budget.
So yes, the already committed projects would continue and so the net recipient would continue to be a net recipient until the currently committed projects were completed.

There is reason to think any other country would be treated differently.
