S&P Global Ratings affirmed its 'AAA' long-term rating on Grinnell College , Iowa's revenue bonds. The outlook is stable. A general obligation of Grinnell College secures the bonds. As of June 30, 2025, college had about $207 million in fixed-rate debt outstanding, which fully amortizes by 2052. The debt has a bullet payment of roughly $61 million due in 2052; however, this poses little to no risk to the college given the size of its financial resources and liquidity. The college does not have any additional debt plans within our outlook period. We assessed Grinnell's enterprise risk profile as extremely strong, characterized by enrollment that grew slightly in fall 2023 and fall 2024, but is expected to be slightly weaker
