Millicom Earnings Call Highlights Growth Amid Integration

Millicom International Cellular Sa ((TIGO)) has held its Q4 earnings call. Read on for the main highlights of the call.

Millicom International Cellular SA’s latest earnings call painted a picture of a company in strong operational health, yet bracing for a more complex near term. Management emphasized accelerating organic growth, widening margins and solid cash generation, while acknowledging legal settlements, integration costs and new market losses that could test execution as leverage temporarily ticks higher.

Revenue Growth and Top-Line Momentum

Service revenues reached $1.55 billion in Q4, up 15.9% year over year, powered by recent Ecuador and Uruguay deals. Excluding these additions, organic service revenue still grew 5.2%, signaling a clear acceleration in the core portfolio and suggesting Millicom’s Latin American footprint is regaining volume and pricing power.

EBITDA Expansion and Margin Strength

Group adjusted EBITDA climbed to $778 million with a robust 47.1% margin, a 25.9% increase versus last year’s quarter. Stripping out Ecuador and Uruguay, EBITDA grew 18% to $732 million, reflecting broad‑based margin expansion as scale benefits, cost discipline and mix improvement flow through the income statement.

Equity Free Cash Flow Outperformance

Over the past 12 months, equity free cash flow increased by $139 million to $916 million, or $864 million when excluding infrastructure sales. Q4 eFCF of $278 million topped management’s own guidance despite one‑off headwinds, reinforcing the company’s cash‑generation credentials as it undertakes an aggressive M&A and integration agenda.

Customer Momentum in Postpaid and Home

Millicom added more than 200,000 postpaid subscribers in the quarter, or 1.8 million including Ecuador and Uruguay, driving its postpaid base to 9.1 million, up 12.6% year over year on an organic basis. The Home segment delivered 40,000 net new homes and a 5.1% rise in the customer base, underscoring demand, even if monetization is lagging.

Guatemala and Colombia Lead Country Outperformance

Guatemala posted a standout quarter with postpaid up 20%, mobile service revenue up 5.9% and Q4 operating cash flow up 17%, contributing to $791 million for the full year. Colombia also impressed, with postpaid and home each growing around 10%, service revenue up 6.9% and record adjusted EBITDA of $174 million at roughly a 44% margin.

B2B and Digital Businesses Gain Traction

Digital service revenues, excluding new perimeter assets, surged 40.7% year on year to $79 million, highlighting the strategic push beyond consumer connectivity. B2B mobile service revenue rose 7%, with the SME segment accelerating to 5% growth, as enterprise clients increasingly adopt Millicom’s integrated digital and mobile offerings.

Executing on M&A and Integration

The company moved quickly to integrate Ecuador and Uruguay, installing new leadership, applying its operating playbook and achieving about a 30% reduction in headcount. Millicom also expanded into Chile through a joint venture with NJJ and acquired full control of Tigo Colombia, with management claiming rapid stabilization and early efficiency wins across these assets.

Leverage Control and Balance Sheet Discipline

Net leverage closed the year at 2.31 times, up from 2.09 times at the start of Q4 but still comfortably below the 2.5 times ceiling, with a pro forma ratio of 2.17 times including Ecuador and Uruguay. Management reiterated a disciplined path to at least $900 million in eFCF in 2026 and a deleveraging plan that aims to bring leverage back into the 2.0–2.5 times corridor by 2027.

Operational Margin Club Reaches New Members

Several markets posted eye‑catching profitability, with Paraguay delivering a 52.1% EBITDA margin and Bolivia around 53%, joining the so‑called “Club 50” of operations above 50% margin. These results underscore the impact of tight cost control and efficient local execution in smaller but highly profitable markets.

Impact of One-Time Legal and Settlement Charges

Management pointed to substantial one‑off legal and settlement payments during the year, including significant amounts tied to regulatory and legal resolutions, which weighed on cash flows. These items distorted working capital and eFCF timing, but were framed as non‑recurring overhangs rather than structural profitability issues.

Coltel Integration and Restructuring Drag

The acquisition of Coltel in Colombia is expected to be a notable short‑term drag, with management guiding to a negative run‑rate eFCF for the business. Turning the asset around will require heavy lifting, including restructuring costs in the triple‑digit million dollar range during 2026, before synergies and network rationalization can fully take hold.

Chile Joint Venture Starts in the Red

Millicom’s new Chilean joint venture with NJJ is currently loss‑making, with management bluntly describing it as “losing money every day” at this stage. The ambition is to reach eFCF neutrality within the year, but investors should brace for near‑term earnings pressure as the team restructures operations and invests to stabilize the franchise.

Home Revenue Softness Despite Subscriber Growth

While the Home business is still adding customers, service revenues in the segment slipped 0.3% year over year, marking a second straight quarter of flat to slightly negative growth. The performance suggests that pricing, competition or usage trends are offsetting subscriber gains, leaving Home as a relative weak spot versus mobile.

Non-Recurring Project Revenues in B2B

The B2B unit’s recent strength was flattered by one‑time government projects, with about $16 million cited across Panama and Colombia that may not repeat. Management acknowledged these non‑recurring items, signaling that investors should normalize growth expectations and focus on underlying enterprise demand trends.

Temporary Leverage Pressure from M&A Cash-Outs

Incoming cash payments for completed deals will push leverage above the stated 2.5 times ceiling in the first half of 2026, notably the roughly $570 million for the remaining Tigo Colombia stake and around $220 million linked to Coltel and related liabilities. Additional outlays, including a large payment associated with another transaction, will further strain metrics before deleveraging resumes.

Macro, FX and Political Risk Backdrop

Management repeatedly highlighted the inherent volatility in Latin American markets, including currency swings, political uncertainty and shifting tax and legal regimes. These factors could erode recent FX tailwinds and pressure margins or cash flows, making diversification and hedging critical to sustaining the group’s current momentum.

Colombia Faces Near-Term Margin Headwinds

Despite Colombia’s standout Q4 performance, the company warned that margins there will soften in Q1 due to a sharp increase in statutory minimum wages. This regulatory move lifts personnel and related costs across the operation, creating a short‑term profitability headwind even as revenue trends remain constructive.

Guidance and Outlook

For 2026, Millicom is guiding to at least $900 million in equity free cash flow, roughly in line with the $916 million delivered over the past year, or $864 million excluding tower proceeds. Management expects newly acquired Uruguay and Ecuador to contribute low‑to‑mid‑double‑digit millions of eFCF, while Coltel will remain a drag as restructuring costs swell, leverage briefly exceeds 2.5 times and then trends back toward that level by year‑end with a medium‑term goal of stabilizing between 2.0 and 2.5 times.

Millicom’s earnings call underscored a company delivering strong growth, expanding margins and solid cash generation, while aggressively reshaping its footprint through acquisitions. Execution on turnarounds in Colombia and Chile, along with managing leverage and Latin American macro risks, will be crucial, but for now management’s strategy and financial targets appear credible and balanced between ambition and prudence.
