Millicom Chief Executive Officer Marcelo Benitez commented:

"The fourth quarter marked another record‑setting period for Millicom and a powerful close to what has been the strongest year in our company's history. Our strategy delivered accelerating topline momentum, with service revenue growing organically 5.2% year‑on‑year to reach an all‑time high of $1.5 billion. This performance reflects our continued disciplined execution of our commercial strategy, particularly the ongoing migration from prepaid to postpaid and our focus on driving fixed‑mobile convergence as well as the successful integration of our expanded footprint in Ecuador and Uruguay. Our operational excellence also translated into exceptional profitability. Through rigorous cost discipline and industry‑leading efficiency, we delivered our highest‑ever quarterly Adjusted EBITDA of $778 million and a record EFCF of $278 million.

These achievements capped off a landmark year for Millicom. In 2025, we generated $916 million in EFCF, surpassing our full‑year target, while maintaining leverage below 2.5x, even after the perimeter expansions in Uruguay and Ecuador. Just as importantly, we executed several major strategic milestones that further strengthened the company. We completed the Lati tower sale, for a total consideration of approximately $975 million, reached a settlement with the DOJ, and advanced a number of other legacy cleanup efforts, all of which position Millicom for greater agility and clarity moving forward.

As we look ahead, Millicom enters 2026 in its strongest position yet, both operationally and financially. Our balance sheet is more robust, our commercial strategy is delivering consistent results, and our regional footprint is generating increasing opportunities for scale and innovation. With this foundation, we have built exceptional momentum and are ready to embark on another transformative year for Millicom."

2026 Financial Targets

Millicom targets 2026 EFCF of at least $900 million and year-end leverage around 2.5x. These targets include restructuring costs of all acquired businesses.

Subsequent Events

On January 5, 2026, Tigo Paraguay signed a Share Purchase Agreement ("SPA") to sell its Mobile Finance business in Paraguay (Mobile Cash Paraguay S.A. and Transcom S.A.) for a base price of $10 million (and a potential $7 million earn-out, contingent of SPA's conditions). The transaction is subject to approval by the Central Bank of Paraguay and Conacom.

Following the closings with SBA, Tigo Guatemala signed an MLA amendment for the use of ground space on January 22, 2026. This amendment has a 15-year term and is for a total annual amount of approximately $13 million (resulting in the recognition of right-of-use assets and lease liabilities for $119 million). Concurrently, the termination of prior lease agreements resulted in a decrease the right-of-use assets by $68 million and lease liabilities by $74 million.

On January 27, 2026, Millicom was awarded 100% of the EPM's remaining shares in UNE EPM Telecommunicaciones S.A. ("UNE" or "Tigo Colombia"), following a winning bid in the public auction conducted by Empresas Públicas de Medellín E.S.P. ("EPM"). Millicom offered COP 418,741 per share, representing a total consideration of COP 2.1 trillion, (approximately $571 million). The transaction closed on January 29, 2026.

On February 6, 2026, Millicom closed the acquisition of Telefónica's controlling 67.5% equity stake in Colombia Telecomunicaciones S.A. E.S.P. ("Coltel") in a tender offer that was conducted in accordance with the terms publicly disclosed, with a price of approximately $214 million for Telefónica's controlling 67.5% equity stake in Coltel.

On February 10, 2026, Millicom, through a jointly controlled vehicle, Celtel Chile, S.L. (owned by Millicom Spain, S.L. at 49% and NJJ Cactus SAS at 51%), completed the acquisition of 100% of the shares of Telefónica Móviles Chile S.A., pursuant to a Share Purchase Agreement (SPA) executed at the same date. The closing consideration was $50 million paid in cash. The SPA also provides for contingent consideration in the form of earn-outs up to $150 million, determined by formulas and procedures set out in the SPA, without recourse to Millicom.

In addition, under a Call Option Agreement signed at closing, Millicom has two 30‑day windows following the fifth and sixth anniversaries of closing to acquire NJJ's entire interest in Celtel Chile, S.L. at a price determined under the agreement's valuation formulas; if Millicom does not exercise, NJJ obtains a subsequent 60‑day option to acquire Millicom's interest using the same pricing methodology.

On February 18, 2026 Tigo Guatemala executed a variable five-year term bank credit facilities with Banco GYT Continental for an amount of GTQ400 million (approximately $52 million).
