Item 8.01. Other Events.

On April 28, 2026, Kemper Corporation (“Kemper”) delivered notice to JPMorgan Chase Bank, N.A., in its capacity as administrative agent under the Company’s Third Amended and Restated Credit Agreement, dated March 15, 2022 (the “Credit Agreement”), pursuant to which Kemper reduced the total borrowing capacity available under the Credit Agreement from $600 million to $350 million effective May 4, 2026. Following this reduction in borrowing capacity, Kemper considers its available sources of liquidity to be sufficient for its present corporate purposes. This action will result in a reduction in annual fees to Kemper under the Credit Agreement, which is consistent with Kemper’s on-going initiative to reduce corporate expenses.
