MILLICOM INTERNATIONAL CELLULAR SA

As further detailed in note 1, Millicom operates in a single region (Latin America), and more specifically in the following countries: Guatemala, Colombia, Panama, Honduras, Paraguay, El Salvador, Bolivia, Nicaragua and Costa Rica.

As further explained in the 2024 Group's Consolidated Financial Statements, the 'Chief Operating Decision Maker ("CODM") assesses performance and allocates resources, based on individual countries, which are its operating segments. The Honduras joint venture is reviewed by the CODM in a similar manner as for the Group’s controlled operations and is therefore also shown as a separate operating segment at 100%. However, these amounts are subsequently eliminated in order to reconcile with the Group consolidated numbers, as shown in the reconciliations below.

Management evaluates performance and makes decisions about allocating resources to the Group's operating segments based on financial measures, such as revenue, including service revenue, and Adjusted EBITDA. Capital expenditures are also a significant aspect for management and in the telecommunication industry as a whole. Management believes that service revenue and Adjusted EBITDA are essential financial indicators for the CODM and investors. These measures are particularly valuable for evaluating performance over time. Management utilizes service revenue and Adjusted EBITDA when making operational decisions, allocating resources, and conducting internal comparisons against historical performance and competitor benchmarks. Additionally, these metrics provide deeper insights into the Group's operating performance. Millicom's Nomination, Talent and Compensation Committee also employs service revenue and Adjusted EBITDA when assessing employees' performance and compensation, including that of the Group's executives. A reconciliation of service revenue to revenue and Adjusted EBITDA to profit before taxes is provided below.
