Monitor regulatory approval timeline (Fed, DIFS) and Grand River shareholder vote. The fixed exchange ratio creates stock-price risk for Grand River electing shareholders tied to ISBA's market price. Watch for any material adverse change in Grand River's adjusted equity below $45.7M, which would reduce cash consideration. No immediate trading catalyst for ISBA given the neutral, routine nature of this S-4 filing.
