Most Popular Narrative: Fairly Valued

Despite recent momentum, the most-followed narrative places Millicom’s fair value at $49.14, almost in line with the last close of $50.33. The close gap between current price and estimated fair value suggests the market may already be reflecting the company’s future prospects.

The market may be overestimating Millicom's future revenue growth by assuming that rapid postpaid penetration and ARPU uplift, driven by digital transformation and rising data demand in Latin America, will consistently materialize. This is despite increasing price competition from low-cost entrants and aggressive offers (e.g., WOM, Telefonica), which could cap ARPU and slow subscriber acquisition, potentially impacting top-line growth.
