NSF lists this award's end date as 31 May 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 September 2028.

Abstract

Einstein’s theory of general relativity is a highly successful and precise description of space and time. One of its most striking and central predictions is the existence of black holes: regions of spacetime where gravity is so strong that nothing, not even light, can escape from them. Another prediction is the existence of gravitational waves, ripples in the geometry of spacetime that propagate at the speed of…
