Millicom International Cellular S.A. (TIGO) - Porter's Five Forces: Bargaining power of suppliers

The bargaining power of suppliers for Millicom International Cellular S.A. (TIGO) is shaped by the specialized nature of critical infrastructure inputs and strategic asset monetization decisions.

Global network equipment vendors hold high power. This stems from the oligopolistic structure of the market for specialized technology required for 5G and Fiber-to-the-Home (FTTH) rollouts. You can see the scale of these commitments in the figures below, which reflect a significant, near-term financial obligation to these key technology partners.

Reliance on tower companies has increased following a major infrastructure transaction. Millicom International Cellular S.A. (TIGO) entered an agreement with SBA Communications for a sale and leaseback of approximately 7,000 towers across Guatemala, Honduras, Panama, El Salvador, and Nicaragua, valued at approximately $975 million, expected to close in mid-to-late 2025.

The terms of this supplier relationship are now long-term and substantial:

• Leaseback term on sold sites is at least 15 years.
• Agreement includes a build-to-suit for up to 2,500 additional sites.
• SBA projects $129 million in site leasing revenues in the first full year.
• SBA projects $89 million in tower cash flow in the first full year.

Spectrum acquisition represents a significant, government-controlled input cost. Following the successful $380 million acquisition of Telefónica's operations in Ecuador in October 2025, the broader spectrum landscape in that country shows high supplier power from the government.

For fiber optic cable and backhaul, supplier power is moderated by Millicom International Cellular S.A. (TIGO)'s own substantial footprint. This internal asset base helps mitigate external dependency for network capacity.

• Fiber-cable footprint as of December 31, 2024: approximately 14 million homes passed.
• Fiber-cable footprint as of March 31, 2025: over 14 million homes passed.

Millicom International Cellular S.A. (TIGO) - Porter's Five Forces: Bargaining power of customers

You are looking at a customer base in Latin America where price is a major driver, even as Millicom International Cellular S.A. (TIGO) successfully migrates users to higher-value plans. The persistent economic backdrop means customers are definitely watching their spending closely. For instance, you saw inflation in a key market like Argentina was still around 40% as of June 2025, which keeps the cost-of-living concerns front and center for the average consumer across the region. This environment forces Millicom International Cellular S.A. (TIGO) to be strategic about its pricing, as evidenced by the mobile service revenue growth of 5.5% year-over-year in Q3 2025, which was explicitly driven by ARPU (Average Revenue Per User) expansion in prepaid, achieved by aligning pricing with inflation. Here's a quick look at the dual nature of the mobile base:

For the prepaid segment, the bargaining power is inherently high because switching costs are low. If a customer is not locked into a contract, moving to a competitor for a better per-minute or per-gigabyte rate is relatively simple. The fact that prepaid volumes remain stable, even as postpaid grows, shows this segment is still price-sensitive and represents a constant pool of potential churn if value propositions falter.

However, Millicom International Cellular S.A. (TIGO) has a strong defense mechanism in its convergence strategy, which bundles mobile and home services under one plan. This bundling directly increases the cost for a customer to switch providers, as they would have to replace multiple services. This strategy is working well in the home business, which added 60,000 new customers in Q3 2025, marking a 5.4% year-over-year increase. More importantly, this bundling keeps home business churn in the low single digits-a clear indicator of sticky customer relationships in that segment. In Colombia, for example, home customers grew 12% to reach 1.6 million HFC and FTTH connections, directly benefiting from this integrated approach.

The postpaid base, while smaller, has higher retention, but this comes with higher expectations. This base grew to 8.9 million customers, a 14% year-over-year increase, showing successful migration from prepaid. Still, these higher-value customers demand a superior network experience and better service quality. If the network performance lags or customer service irritates them, their increased spending power means they can exert significant pressure for better value or switch to a rival offering a premium experience. For instance, in Colombia, the postpaid customer base alone rose 12% year-over-year in Q3 2025, showing the success of upselling, but these customers are less forgiving of service gaps.

• Low switching costs for the stable prepaid base maintain high customer leverage on price.
• Convergence strategy successfully locks in home customers, resulting in low single digits churn.
• The growing postpaid base of 8.9 million customers demands service quality commensurate with their spend.
• Millicom International Cellular S.A. (TIGO) is actively managing ARPU in prepaid by aligning pricing with regional inflation trends.

Millicom International Cellular S.A. (TIGO) - Porter's Five Forces: Competitive rivalry

The competitive rivalry in Millicom International Cellular S.A. (TIGO)'s core Latin American markets remains fierce, characterized by a tight race for subscriber share and technology leadership. You see this most clearly in Colombia, where the landscape is dominated by three major mobile network operators (MNOs).

As of the end of December 2024, the Colombian mobile market held almost 103mn mobile lines total. América Móvil's Claro was the clear leader with 52.0mn connections, followed by Telefónica's Movistar with 20.8mn, and Millicom's Tigo with 16.7mn connections. WOM, recently saved from bankruptcy, held 7.7mn subscribers.

The battle for next-generation services is intense. By June 2025, 5G technology accounted for 12.4% of total mobile internet access, reaching 6.03 million connections, a massive 185.5% increase compared to 2024. Claro leads this segment with a 68.4% share as of June 2025, while Tigo held 15.7% and Movistar held 15.9%. In fact, Claro operated 92.2% of the nation's 1,433 active 5G sites as of June 2025, with Tigo/Movistar operating the remainder.

Millicom International Cellular S.A. (TIGO) is actively moving to consolidate its position, which directly impacts rivalry levels. This is evident in the M&A activity:

• Acquisition of Telefónica Uruguay for an enterprise value of $440M.
• Successful completion of the acquisition of Telefónica's operations in Ecuador for $380 million on October 30, 2025.
• The Ecuador deal added 5.2mn mobile customers, representing 28.3% of that market as of February 2025.
• The Uruguay deal added another 1.5mn mobile lines.
• The planned acquisition of a 67.5% stake in Movistar Colombia (Coltel) was valued at $400 million.

By March 2025, before the full integration of these deals, Millicom had 41.6mn mobile subscribers across Latin America. The company incurred a $25 million charge related to its strategic exit from Africa to fund this pivot.

Competition is inherently capital-intensive, driven by the necessary build-out of next-generation networks. Millicom projects its full-year 2025 Cash CapEx to be $677 million, matching the 2024 figure. This spending is set against a backdrop where leading Latin American telcos, including América Móvil and Millicom International Cellular S.A. (TIGO), are projected to have a combined capex of over $16bn in 2025, excluding acquisitions. For context, América Móvil allocated a $7 billion capital expenditure budget for 2024 to accelerate its 5G rollout.

The strategy of acquiring competitors is a direct move to reduce rivalry and drive consolidation. The combined Tigo and Movistar mobile internet connections under Millicom's control reached more than 17 million in the first half of 2025, still significantly behind Claro but far ahead of the fourth-ranked provider, WOM, which had 2.67 million connections. Millicom expects the Uruguay acquisition to be Equity Free Cash Flow (EFCF) accretive as early as 2026. The company's leverage ended Q1 2025 at 2.47x, with a stated aim to maintain leverage below 2.5x by 2026.

Here is a snapshot of the competitive structure in key markets based on recent data:

The capital intensity is further illustrated by the spending plans of the major regional players:

• Millicom International Cellular S.A. (TIGO) Projected 2025 Capex: $677mn.
• América Móvil Projected 2025 Global Investment: $6.7bn.
• Combined Leading LatAm Telco Capex (2025 Est.): Over $16bn.
• Colombia 5G Connections (End-Dec 2024): 3.8mn (7.7% of total mobile internet accesses).

Millicom International Cellular S.A. (TIGO) - Porter's Five Forces: Threat of substitutes

The threat from substitutes remains a significant structural pressure point for Millicom International Cellular S.A. (TIGO), particularly as Over-The-Top (OTT) applications directly cannibalize traditional revenue streams like voice, SMS, and Pay-TV services.

This substitution effect is defintely structural; you see evidence of people using less traditional voice services, which is mirrored globally by the increasing cost and declining appeal of legacy SMS for enterprise use cases. For instance, international SMS rates have spiked dramatically, in some cases rising by 40% to 500%, making alternatives more compelling for businesses reaching customers in South America.

In many developing markets where Millicom International Cellular S.A. (TIGO) operates, hyper-scalers like Google are actively moving significant traffic away from SMS channels, indicating a clear industry pivot away from this traditional service.

Millicom International Cellular S.A. (TIGO) counters this substitution risk by aggressively scaling its B2B digital services portfolio, which includes cloud, cybersecurity, and SD-WAN offerings. This strategic pivot is showing strong results in the latest reporting periods.

Here's a quick look at the numbers illustrating the dual dynamic of the threat and the company's digital response:

The reliance on data-centric services is clear, but this also exposes Millicom International Cellular S.A. (TIGO) to alternatives that bypass traditional network infrastructure entirely.

The low-cost alternative of Wi-Fi-only communication, enabled by unlicensed spectrum technologies, presents a persistent substitution threat for data access, especially in areas with high fixed broadband penetration or where mobile data costs remain a barrier for end-users.

The structural shift is evident in the growth disparity:

• Digital Services Revenue Growth: 35% year-over-year.
• Total Mobile Postpaid Customer Growth: 14% year-over-year (Colombia Q3 2025).
• Traditional Voice/SMS Revenue: Implied decline/stagnation relative to digital growth.

Millicom International Cellular S.A. (TIGO) - Porter's Five Forces: Threat of new entrants

The threat of new entrants for Millicom International Cellular S.A. (TIGO) in the late 2025 landscape remains decidedly low, primarily due to formidable structural barriers to entry across capital, regulatory, and operational domains within its core Latin American markets.

Extremely High Capital Expenditure Requirements

Launching a competitive mobile and fixed network operation requires massive upfront and ongoing capital. Building out the necessary infrastructure, especially for next-generation services like 5G and Fiber-to-the-Home (FTTH), demands significant investment that deters most potential entrants. Millicom International Cellular S.A. (TIGO) itself has signaled its commitment to this scale of spending, planning to keep its annual Capital Expenditure (CapEx) envelope around ~$700 million for 2025. A new competitor would need to commit comparable, if not greater, sums just to achieve parity in network coverage and quality.

Prohibitive Spectrum Acquisition Costs and Taxation

Securing the necessary radio frequency spectrum licenses is a major hurdle. Spectrum pricing policies in Latin America show significant variation, and in some cases, costs are inflated by high annual taxes charged to license holders, as seen in Mexico. Industry experts have called for abolishing policies that unnecessarily raise spectrum costs to facilitate infrastructure deployment. While a direct comparison to European spectrum costs is complex, the focus on revenue maximization through high auction prices in the region acts as a significant financial barrier, effectively pricing out smaller or less capitalized players before they even begin network construction.

Significant Regulatory and Permitting Hurdles

Beyond the direct financial outlay, navigating the regulatory environment presents a bureaucratic challenge. In many Latin American countries, local regulations often conflict with federal authority, resulting in municipal permitting processes that are frequently restrictive, non-transparent, and bureaucratic for passive infrastructure deployment. These barriers increase the opportunity cost of deployment significantly. While some progress is being made-El Salvador introduced a single platform for unified fees, and Peru is drafting proposals to reduce environmental report approval times-the general complexity remains a deterrent. Furthermore, in some jurisdictions, specific fees are imposed with the purpose of either limiting infrastructure deployment or increasing government revenue, sometimes on an ad-hoc annual basis.

Scale of Incumbent Operations

The sheer scale of Millicom International Cellular S.A. (TIGO)'s established operations presents a formidable competitive moat. For a new entrant to pose a credible threat, it must be able to match the incumbent's existing market presence and financial footprint. Millicom International Cellular S.A. (TIGO)'s total revenue for the trailing twelve months ending Q3 2025 stood at $5.59 billion. This revenue base supports ongoing network investment, economies of scale in procurement, and the ability to absorb regulatory shocks that might cripple a smaller, newer competitor.

The barriers to entry can be summarized by the required investment profile:

• High annual CapEx commitment, estimated near $700 million for Millicom.
• Costly spectrum acquisition, often burdened by high regional taxes.
• Bureaucratic municipal permitting processes slowing deployment.
• Need to match incumbent scale, evidenced by TIGO's $5.59 billion TTM revenue.

The combination of massive required capital, high spectrum costs, and complex, often unpredictable municipal red tape means that only a well-funded, highly strategic global or regional player could realistically consider entering these markets, and even then, the path is fraught with friction.
