Millicom International Cellular S.A. (TIGO) saw its stock price soar 5.77% during intraday trading on Thursday. The significant move followed the company's release of its fourth-quarter 2025 financial results, which substantially exceeded market expectations.

The telecommunications provider reported quarterly earnings of $1.50 per share, crushing the analyst consensus estimate of $0.88 by 70.45%. Revenue for the quarter reached $1.652 billion, a 15.69% increase year-over-year and above the estimated $1.566 billion. The company also highlighted record service revenue growth, driven by its commercial strategy including the migration from prepaid to postpaid services and the successful integration of its expanded footprint in Ecuador and Uruguay.

CEO Marcelo Benitez stated the quarter marked "another record-setting period" and the close of "the strongest year in our company's history," citing exceptional profitability and a robust balance sheet. The positive earnings surprise and optimistic outlook for 2026, including a target for equity free cash flow of at least $900 million, provided a clear catalyst for the stock's upward movement.
