NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2027.

Abstract

"BobberOne" is a low-cost, portable float that will use acoustic sensing to detect regionally important zooplankton, fish, and marine mammals in near real-time. Physical processes such as currents and turbulence transport phytoplankton and small zooplankton, influencing the distributions of larger zooplankton, fish, and higher-level predators. Predation pressure, in turn, drives prey avoidance behaviors that…
