Longleaf Partners Global Fund stated the following regarding Millicom International Cellular S.A. (NASDAQ:TIGO) in its fourth quarter 2025 investor letter:
“Millicom International Cellular S.A. (NASDAQ:TIGO) – Latin American telecommunications operator Millicom was a contributor for the year. The company extended its strong 2024 performance through 2025, with the share price tracking operational delivery and the visible inflection in equity FCF we flagged in prior letters. This was driven by a focused new management team and an aligned majority shareholder partner in Iliad Group (Atlas). The business exceeded its already twice-raised 2024 FCF guidance and guided to material further growth in 2025, while reaching its 2.5x leverage target and increasing dividends and buybacks. The discount to our appraisal narrowed with this positive performance and solid Colombian M&A news. What was an attractive outlier at a double-digit dividend yield earlier in the year has now aligned with peers at mid-single-digit levels. With the value gap largely closed and limited upside remaining on a risk-adjusted basis, portfolio discipline dictated our exit in the third quarter.”
