AmperCap Acquisition Company

Item 1.01. Entry into a Material Definitive Agreement. As previously disclosed on a Current Report on Form 8-K dated June 5, 2026, AmperCap Acquisition Company (the “Company”) entered into an Administrative Services Agreement (the “Original Agreement”) with AmperSPAC LLC, a Delaware limited liability company and the Company’s sponsor (the “Sponsor”) on June 2, 2026. Pursuant to the Original Agreement, the Company agreed to reimburse the Sponsor up to $5,000 per month for certain office space, utilities and secretarial and administrative support as may be reasonably required by the Company (the “Services Fee”), beginning on the Listing Date and continuing monthly thereafter until the Termination Date (each as defined in the Original Agreement). On July 31, 2026, the Company entered into an Amendment to Administrative Services Agreement (the “Amendment”) with the Sponsor to provide for the payment of the Services Fee to be made on a quarterly basis. Effective July 1, 2026, such payments shall be made in advance on a quarterly basis in the first month of each calendar quarter; provided that any portion of the Services Fee that has been paid for a given month but has not accrued as of the Termination Date shall be refunded to the Company within five (5) business days of the Termination Date. The foregoing description of the Amendment does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Amendment, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
