Item 1.01. Entry into a Material Definitive Agreement.

Palmer Square BDC Funding I LLC (the “SPV”), a wholly owned subsidiary of Palmer Square Capital BDC Inc. (the “Company”), provided written notice (the “Commitment Reduction Notice”) of its intent to reduce the amount of aggregate commitments to $350 million from $525 million in accordance with and as permitted under that certain credit facility (the “Credit Facility”) among the SPV, as borrower, Bank of America, N.A., as administrative agent, BofA Securities, Inc., as sole lead arranger and sole book manager, and the lenders from time to time a party thereto. The other terms of the Credit Facility were not changed. Such reduction in the aggregate commitment of the SPV under the Credit Facility pursuant to the Commitment Reduction Notice was effective as of July 1, 2026. The SPV pays commitment fees on the unused capacity of the Credit Facility and the reduction of commitments will reduce this unused capacity. The Company believes this is a tool to maintain an appropriate amount of unused capacity to support future portfolio growth while also reducing unnecessary costs.
