Millicom (TIGO) Q2 2026 earnings review

M&A Integration Powers Record Cash Flow

Millicom delivered a transformative Q2 2026, surpassing $1 billion in quarterly Adjusted EBITDA for the first time. The consolidation of Coltel (Colombia) alongside operations in Ecuador and Uruguay drove a massive 60% YoY increase in service revenue. More importantly, organic service revenue grew 5.4% and organic EBITDA grew 9.1%, proving the core business remains healthy amid the M&A noise. The acquisitions are already cash-accretive, driving a record $327M in Equity Free Cash Flow (EFCF) and prompting management to raise full-year EFCF guidance to ~$1.1 billion. While headline Net Income plummeted 84% YoY, this is purely an accounting artifact—Q2 2025 included a massive $604M gain from a tower sale. Underlying operating profit actually expanded 30%.

🐂 Bull Case

M&A Playbook Validated

Ecuador and Uruguay have rapidly scaled to ~46-49% margins (up from ~30% pre-acquisition), proving Millicom's turnaround strategy works and generates immediate cash flow.

Operating Leverage

Organic EBITDA growth (9.1%) significantly outpaced organic service revenue growth (5.4%), demonstrating strict cost discipline and the high-margin nature of pre-to-post subscriber migrations.

🐻 Bear Case

Debt and Financing Burden

Net financial expenses surged 65.8% YoY to $279M, driven by M&A financing and higher lease liabilities. Leverage sits at 2.73x, above the <2.5x target.

Home Segment Optical Illusion

Home revenue grew 3%, but management admitted 80% of this was a one-off boost from FIFA World Cup broadcasting rights. Underlying subscriber growth is virtually flat.

⚖️ Verdict: 🟢

Bullish. Millicom is successfully executing a complex, multi-country M&A strategy without blowing up its balance sheet. Hitting $1 billion in quarterly EBITDA and raising EFCF guidance proves the integration playbook works. The core cash-generation engine is accelerating.

Key Themes

DRIVER 🟢

Pre-to-Post Migration Engine

The strategy to migrate prepaid users to postpaid plans continues to be the primary organic growth driver. Excluding Coltel, a staggering 66% of new postpaid sales came from prepaid conversions. This strategy directly fueled an 18.9% YoY increase in mobile ARPU to $7.10, extending customer lifespans and drastically improving unit economics.

DRIVER 🟢

Accretive M&A Integration

The newly acquired assets are performing exceptionally well. Ecuador delivered a 48.9% Adjusted EBITDA margin in Q2, while Uruguay hit 46.0%. Management noted these businesses have rapidly transitioned from ~30% margins under prior ownership to performing in line with the Millicom group average, generating immediate equity free cash flow.

DRIVER

B2B Digital Services Momentum

The B2B segment delivered $401M in service revenue, growing 3.8% organically. The standout within B2B is Digital Services (cloud, cybersecurity, SD-WAN), which surged 14.1% YoY to $120M. Management specifically highlighted success in securing government cybersecurity contracts, transitioning the B2B mix from basic connectivity to high-margin managed services.

CONCERN NEW 🔴

Home Segment Artificial Boost & Harmonization

The Home segment reported 3% organic revenue growth, but this masks underlying weakness. Management conceded that 80% of this growth stemmed from a one-off boost related to FIFA World Cup broadcasting rights (pay-per-view, data top-ups, advertising). Furthermore, the company reported -79k Home net adds due to subscriber counting 'harmonization' in Colombia. Once the World Cup effect fades in Q3/Q4, Home revenue growth could stagnate.

CONCERN NEW 🔴

Ecuador Margin Contraction Imminent

While Ecuador's 48.9% margin is currently a bright spot, CFO Bart Vanhaeren explicitly warned of a multi-percentage point margin contraction in the second half of 2026. The culprit is the planned launch of the Tigo brand in the country, which will require heavy incremental marketing and promotional investments.

CONCERN

Mounting Financial and Lease Expenses

The cost of Millicom's aggressive M&A expansion is visible below the operating line. Net financial expenses spiked 65.8% YoY to $279M. Furthermore, cash lease payments nearly doubled YoY to $161M, driven by perimeter expansion and the recent Lati tower sale-and-leaseback transaction. This creates a higher fixed-cost hurdle for cash generation.

CONCERN NEW 🔴

Bolivia FX Regime Shift

The Bolivian government transitioned from a fixed exchange rate peg to a flexible, market-driven regime, resulting in a severe 58.1% YoY devaluation of the Boliviano against the USD. While management has largely localized the P&L and utilized local bank loans (adding $44M in BOB debt in July) to hedge cash flows, this remains a massive headwind to reported consolidated USD metrics.

Other KPIs

Paraguay Adjusted EBITDA Margin 56.9%

A remarkable expansion from 50.5% a year ago. The 16.9% YoY EBITDA growth outpaced the 3.4% revenue growth, driven by aggressive operational efficiency gains in direct costs and favorable FX tailwinds (the Guarani appreciated against the USD, lowering dollar-denominated content costs).

Net Income $109 million

Down 84% YoY from $676M. However, this is entirely a base-effect optical illusion. Q2 2025 included a $604M one-off gain from the partial closing of the Lati infrastructure tower deal. Excluding this, underlying operating profit actually grew 30.4% YoY to $462M.

Guatemala Service Revenue $382 million

Guatemala remains Millicom's most consistent cash cow, delivering its strongest quarterly performance in 10 years. Service revenue grew 5.9% YoY, fueled by an aggressive 19% expansion in the postpaid customer base and disciplined pre-to-post migration.

Guidance

FY26 Equity Free Cash Flow ~$1.1 billion

Accelerating. Management raised this from the prior 'at least $900 million' target. This implies roughly 20% YoY growth compared to FY25's $916M. The upgrade reflects strong operating leverage and faster-than-expected cash flow accretion from the newly acquired operations.

FY26 Year-End Leverage Below 2.5x

Stable. The company expects to deleverage from the current 2.73x back below its 2.5x target by year-end. This demonstrates management's confidence that the cash generation of the enlarged portfolio can absorb the heavy M&A and restructuring debt.

Key Questions

Home Segment Post-World Cup

With 80% of Q2's 3% Home revenue growth driven by one-off World Cup broadcasting effects, what is the underlying organic growth trajectory expected for the Home business in Q3 and Q4 once this catalyst fades?

Ecuador Rebranding Costs

You warned of margin contraction in Ecuador due to the upcoming Tigo brand launch. Can you quantify the expected OPEX impact in dollars, and how many quarters do you expect this elevated marketing spend to persist?

Coltel Restructuring Horizon

Colombia reported $32M in restructuring costs this quarter. Are we nearing the end of the heavy integration expenses for Coltel/Tigo UNE, or should we expect similar run-rates through the back half of the year?

Bolivia Cash Upstreaming

Given the transition to a flexible FX regime and severe devaluation in Bolivia, what is your current ability to upstream cash from this entity, and do you foresee any need for further asset write-downs?
