Is it possible to request a no-cost extension at the end of the grant period if there are unexpended funds?
No, by law all Federal agencies are required to cancel any remaining grant balances by September 30th of the 5th fiscal year after the award funds were issued. This means that after 5 years, any unspent grant money is by law returned to the Treasury and is no longer available for expenditure. Because the New Innovator awards are multi-year funded (all award funds are issued up front), the 5-year deadline coincides with the end of the project period, and therefore, no-cost extensions cannot be allowed.
