Mobile consolidation: ambition is essential, but so are credible numbers

No-one enters a mobile merger expecting the estimated financials and related synergies to be wrong. But deal after deal, operators (and the investors backing them) find financial assumptions no longer stack up once the true complexity of integration becomes apparent. And when confidence in the numbers slips, so does investor support.

Stakeholders have become more demanding. After years of missed synergy targets, shareholders, lenders and regulators want answers earlier, and in more detail. They are less willing to accept optimistic projections on trust.

A strong strategy is no longer enough. If you are building a consolidation business case, the numbers must stand up to scrutiny across network complexity, operating model design and execution risk.

The business case is where every M&A begins, and it is what every investor, regulator and shareholder will probe first. There are no second attempts.

The anatomy of a consolidation business case

Strip any merger back to its core and you will find three synergy categories: revenue, opex and capex. The relative weight of each category depends on the market and the specific merger at hand. And the model is only as strong as its weakest assumption.

Revenue synergies assume beforehand that the merged operator will be worth more than the two entities separately. The value comes from reduced churn, increased market share and improved pricing power, all driven by lower competitive intensity. Of the three synergy categories, revenue synergies are the most attractive. But they are also the most fragile.

In developing Asia–Pacific markets, pricing power has been one of the primary drivers of consolidation synergies. India's mobile market consolidated from more than a dozen operators to three dominant players and one minor operator between 2012 and 2018, and industry ARPU has almost doubled since the lows of 2016–2017. 

Opex and capex synergies matter more in markets where revenue growth is limited:

• Network opex savings come from eliminating duplicated sites and rationalising IT systems and OSS/BSS.
• Non-network opex savings come from consolidating distribution, sales and retail channels.
• Capex savings come from combining spectrum assets and re-planning the network based on the existing footprint of the two consolidating operators, and also from reduced ongoing maintenance spend from network consolidation.

The business case faces different tests from different stakeholders. Investors and boards weigh synergies against the acquisition price and the debt/equity structure. Regulators examine post-merger market structure, impact on competition and pricing. But all of them ask the same thing: can you make good on these numbers? Because synergies that look clean on a slide deck still have to be delivered on the ground. Value is not declared in a deck; it is earned in delivery.

Where financial assumptions break down

Having supported over 1100 transactions across technology, media and telecoms (TMT) in the past 5 years, we have seen where consolidation business cases tend to unravel: revenue delivery and network integration.

Revenue assumptions are the hardest to protect during consolidation. Management attention gets pulled into the mechanics of combining two businesses – workforce restructuring, brand consolidation, network and systems integration – and the activities that sustain or grow the top line suffer as a result. Churn does not pause for a merger and customers do not wait for integration to settle. If confidence drops, they leave. 

Network integration is where most business cases meet their biggest test. Large operators carry different radio access network (RAN) vendors, towercos, billing platforms and IT systems. Bringing them together at scale is messy, and the complexity is routinely underestimated in three ways:

• The consolidation opportunity is overstated. Business cases fail to account for ground realities like site lease expiry timelines, actual site capacity and the operational and technical dependencies between overlapping infrastructure.
• Integration timelines are too aggressive. Decommissioning sites, equipment relocation and vendor complexity exceed projections. When networks are integrated within 1 to 2 years, the merger is far more likely to succeed. If it takes longer and related implications are not budgeted in the business plan, costs compound and synergy targets recede.
• Integration costs are under-provisioned. The expenditure required to decommission sites, exit contracts and manage the physical transition is frequently larger than what is budgeted in the business case.

India's recent consolidation history is a case in point. Two major operators, each with ~150 000 sites, attempted to merge networks. The projected savings did not materialise because site-level complexity had been underestimated. Revenue targets compounded the problem, and management found itself fighting to retain existing revenue rather than growing it.

The consequences of getting the numbers wrong

For many operators, shortfalls only become visible once execution is underway, by which point they have already committed to the targets.

In our experience, the strongest consolidation cases are those subjected to early challenge, both internally as well as by independent firms such as Analysys Mason, to avoid consequences such as: 

Integration taking longer and costing more than planned

Network complexity exceeds what the business case assumed. Decommissioning timelines slip, vendor dependencies prove harder to resolve and the cost of managing the integration grows. 

Investor confidence weakening

When the numbers that underpinned the deal structure are not met, boards and shareholders lose faith in management. Appetite for further capital commitment declines, which constrains the very investment needed to fix the problem. 

And when the shortfall becomes apparent, management starts cutting deeper than planned – headcount, network investment, anything that closes the numbers – which makes the underlying problem worse. It becomes a downward spiral that is difficult to reverse. 

Debt lingering longer than expected

Many consolidation deals are highly leveraged. Underperformance against the projections used to structure that leverage causes debt covenants to tighten and refinancing costs to rise. Regulators may also intervene with price controls or mandated investment obligations if the operator fails to meet its commitments. Debt that was meant to accelerate value creation becomes a long-term constraint.

The cycle self-reinforcing

Once an operator is underperforming against its targets, getting approval for further investment becomes harder. But without that investment, the network does not improve, revenue stays flat, and the operator falls further behind. We have seen organisations stuck in this position for years; underinvested, underperforming and short of options. 

But it does not have to be like this… 

How operators should build a consolidation business case

From our experience, business cases stand up to scrutiny when commercial, technical, operational and financial inputs are worked through together from the outset – and the operator's management team and business units have been contributing from the earliest stages.

Each layer of the model needs to be tested against the realities of the market and the network:

• Revenue assumptions need to reflect realistic post-merger competitive dynamics, accounting for how rivals are likely to respond.
• Opex assumptions need to be built from detailed site-level operational data.
• Capex projections need to reflect the true cost, complexity and timeline of integration, including what it takes to decommission infrastructure and exit contracts.

Speed of network integration also matters enormously. In a recent mobile merger in Indonesia, management made network integration its priority and completed the core work within 18 months. 

That speed changed the narrative. Instead of fighting internal complexity, leadership could focus on customers, product innovation and growth. The result was greater momentum.

Two things consistently separate the mergers that deliver from those that do not:

1. Board engagement from the beginning. Boards need to be active participants, not a final approval step. The best outcomes we have seen come from boards getting involved early and asking the right questions, especially on the material synergy areas. 
2. External advisers from day one. Advisers like Analysys Mason, which have worked across multiple mergers and geographies, know where business cases tend to diverge from delivery. An independent perspective is critical to building a credible business case. The earlier these conversations happen, the fewer problems tend to emerge once the deal is in motion.

None of this guarantees a successful merger. However, it helps ensure the spreadsheet and reality stay aligned. After all, ambition gets the deal approved, but credible numbers get it delivered.

Credibility is built before the deal is announced 

Time and again, we have seen deals run into problems during execution that could have been avoided if the right work had been done at the business case stage. 

The assumptions that get locked in are the ones that boards will approve, regulators will test and investors will hold you to; there is no opportunity to revisit them once the deal is in motion.

But there is no template for building this business case. Critical assumptions vary from deal to deal, which is why breadth of experience matters. Analysys Mason has worked on 195 transaction projects in 2025, with a combined deal value of USD41 billion. We can quickly recognise where a model is likely to diverge from what can be delivered.

We understand that ambition drives deals forward. But we also know that ambition without credible assumptions is a risk that operators, investors and regulators are no longer willing to take. The numbers you lock in are the numbers you live with.
