According to a post from Ted David (veteran radio/tv broadcaster, now retired) on the NYRMB, the future WHSQ/ESPN 880 will be "contractually obligated" to continue airing CBS News on the Hour for 18 months–until first quarter 2026 at the latest.
I'm not doubting him, but I will say that typically, stations in this situation are only contractually obligated to carry the commercials, not the programming. But who knows what these folks signed?
