Insights

Equity analyst – Latin American telecoms

Telecom Argentina is absorbing a controlled subsidiary, consolidating operations from 2026.

The filing states that Telecom Argentina will merge with its controlled company TSMA, acting as the absorbing entity, with effect from January 1, 2026. From that date, TSMA’s operations will be considered to be carried out by Telecom Argentina, meaning the business currently in TSMA will be reported directly under the parent.

The planned Consolidated Special Merger Financial Situation Statement as of December 31, 2025 suggests a structured accounting approach to the reorganization. The document does not quantify assets, liabilities, or any merger consideration, so the financial impact cannot be assessed from this information alone.

Subsequent financial statements for periods after January 1, 2026 should reflect the merged structure and may provide more detail on how TSMA’s operations affect Telecom Argentina’s consolidated results.
