ENGLISH SUMMARY OF THE LOAN AGREEMENT, DATED OCTOBER 6, 2025, BETWEEN GRUPO DE COMUNICACIONES DIGITALES, S.A., AND BAC INTERNATIONAL BANK INC.1 On October 6, 2025, Grupo de Comunicaciones Digitales, S.A. (the “Borrower”) entered into a loan agreement (together with its schedules and exhibits, the “Agreement”). The parties to the Agreement are as follows: (i) the Borrower, in such capacity, and (ii) Bac International Bank Inc., as lender (the “Lender”). The following is the summary of the material terms and conditions of the Agreement. In addition to the material terms and conditions that have been summarized herein, the Agreement also includes other customary provisions including, among others, representations and warranties, fees and expenses, amendments and assignment. Loan: Pursuant to the Agreement, the Lender grants to the Borrower an unsecured term loan. Sum of Loan: The Lender grants to the Borrower a loan for the total sum of USD 110,000,000, which shall be disbursed in one disbursement upon completion of all conditions precedent provided in the Agreement (the “Disbursement Date”). Term of Loan: The Loan shall mature sixty-six (66) months after the Disbursement Date (the “Maturity Date”). Payment of Principal and Interest: The Borrower undertakes to make interest payments in twenty-two (22) quarterly installments and the principal payment upon maturity. Interest will be automatically debited from the Borrower’s account held with the Lender on the seventeenth (17th) day of the month following the Disbursement Date and quarterly thereafter on the seventeenth (17th) day of each corresponding quarter. Any remaining balance shall be payable on the Maturity Date in a single installment. Ordinary Interest: The Loan shall accrue interest based on a three-month Term SOFR rate plus a margin of two-point eighty-five percent (2.85%) per annum; provided, that in no event shall the interest rate be less than five percent (5%). Interest will be calculated based on the actual number of calendar days elapsed using a 360-day year. Past-due interest may be capitalized at the Lender’s option and will accrue interest at the same rate as the principal. In addition to interest, the Borrower shall pay FECI2 fees where applicable under Panamanian law, though the Lender must return these funds if the Superintendency of Banks of Panama determines they do not apply and issues a refund. Punitive Interest: Any payment default shall accrue punitive interest on outstanding principal and accrued interest at a rate of 18% per annum (or the maximum rate permitted by Panamanian law). 1 This summary is being filed pursuant to 17 CFR 240.12b-12(d). 2 “FECI” means the rate for the Special Interest Compensation Fund (Tasa para el Fondo Especial de Compensación de Intereses), created by Law 4 of May 17, 1994, as amended.

Other payment obligations: The Borrower shall bear all costs, taxes, and insurance related to the Agreement, including appraisals, notary fees, legal fees, and stamp taxes.

The Borrower shall also be responsible for maintaining all required insurance policies, which must be endorsed in favor of the Lender; failure to provide proof of payment or renewal within the stipulated timeframes may result in the Lender declaring the Loan immediately due and payable.
