In addition, the Amended & Restated KY Power Agreements move the planned delivery of Muskie’s second 500 MW phase from 2030 to 2029, subject to Kentucky Public Service Commission approval and Kentucky Power’s construction schedule. The first 500 MW phase at Muskie remains targeted to begin ramping in 2028. The Amended & Restated KY Power Agreements were executed on October 1, 2026.

Financing Strategy Update In connection with the development of its data center campuses, the Company intends to increase the size of its existing senior secured revolving credit facility and is also seeking to raise additional senior secured debt to further support letter of credit needs in connection with the Company’s long-term power development partnerships with utilities. The upsize of the existing revolving credit facility will be subject to customary closing conditions, and there can be no assurance that the Company will obtain any additional financing.
