Chimera Investment Corp. CIM Number of deferred compensation plans

The Compensation Committee of the Board of Directors of the Company had previously approved a Stock Award Deferral Program, or the Deferral Program. The Deferral Program consisted of two distinct non-qualified deferred compensation plans within the meaning of Section 409A of the Code, as amended, one for non-employee directors (the “Director Plan”) and one for certain executive officers (the “Executive Officer Plan”). Under the Deferral Program, non-employee directors and certain executive officers could elect to defer payment of certain stock awards made pursuant to the 2023 Plan. Deferred awards are treated as deferred stock units and paid at the earlier of separation from service or a date elected by the participant who is separating. Payments are generally made in a lump sum or, if elected by the participant, in five annual installments. Deferred awards receive dividend equivalents during the deferral period in the form of additional deferred stock units. Amounts are paid at the end of the deferral period by delivery of shares from the 2023 Plan (plus cash for any fractional deferred stock units), less any applicable tax withholdings. Deferral elections do not alter any vesting requirements applicable to the underlying stock award. On November 5, 2024, the Compensation Committee of the Board of Directors of the Company irrevocably terminated the Executive Officer Plan and suspended new deferral elections under the Director Plan. The Executive Officer Plan was liquidated as of November 30, 2025, and all amounts outstanding under the Executive Officer Plan on the liquidation date were paid at that time in accordance with applicable tax rules. All deferrals previously made under the Director Plan will remain outstanding, and all deferrals pursuant to prior elections made by directors will be paid on the originally scheduled payment dates. At both June 30, 2026 and December 31, 2025, there are approximately 92 thousand shares for which payments have been deferred until separation or a date elected by the participant. At June 30, 2026 and December 31, 2025, there are approximately 310 thousand and 269 thousand DERs earned but not yet delivered, respectively.
