Singapore’s Telco Price War May Have Reached Its Economic Limit. Is StarHub-M1 the Exit?

For years, Singapore’s mobile market has offered consumers something investors generally dislike: more competition, more capacity and lower prices without a corresponding increase in industry profits.

That model is now becoming harder to sustain.

StarHub’s underlying EBITDA excluding Ensign fell sharply in the first half of 2026, while its mobile-service revenue declined. Singtel’s Singapore operations are also facing pressure. Meanwhile, the failed attempt by Simba to acquire M1 has left the country’s four-network-operator structure intact. StarHub subsequently moved MyRepublic’s 4G customers onto its own network, adding another layer to the industry’s reshaping.

The obvious conclusion is that Singapore needs a telco merger.

But the more interesting investment question is:

Would a StarHub-M1 combination actually create value — or merely combine two businesses whose economics are already deteriorating?

That distinction matters enormously for shareholders.

A merger can remove duplicate costs.

It can also remove a competitor.

The first creates synergies.

The second creates pricing power.

The second may ultimately be worth far more.

The real problem is not subscribers. It is the economics of each subscriber

Investors often assess telecom companies through subscriber numbers.

That is increasingly the wrong metric for Singapore.

The market is already highly penetrated. Adding another mobile customer does not necessarily create much economic value when operators compete aggressively on price.

The more important question is:

How much cash flow can each customer generate after network, spectrum, marketing and customer-acquisition costs?

This is where Singapore’s telco economics have become problematic.

StarHub’s mobile-service revenue declined 10.5 per cent year on year in H1, while blended mobile ARPU fell to S$20 from S$21. Singtel Singapore’s mobile ARPU similarly declined to S$22 from S$23.

Those numbers may appear small.

They are not.

A one-dollar reduction in monthly ARPU across a large subscriber base compounds into a substantial annual revenue loss.

And unlike a retailer selling more products, a telco cannot necessarily compensate by dramatically increasing usage. Network capacity is already expensive, while customers increasingly expect unlimited or high-data allowances at low prices.

This creates a vicious cycle:

lower prices → lower ARPU → weaker margins → pressure to cut costs → less room to invest → greater emphasis on acquiring subscribers → further price competition.

That is the industry’s real problem.

Why consolidation could be worth more than the cost savings

The strongest argument for a StarHub-M1 merger is not that it could eliminate duplicated corporate functions.

It is that Singapore may have too many network operators for the economic size of the market.

DBS estimates a potential StarHub-M1 combination could generate around S$65–75 million of annual synergies, equivalent to roughly 9–11 per cent of combined 2026 EBITDA in its analysis.

That is meaningful.

But cost synergies are only the first layer.

The bigger opportunity is potentially restoring industry pricing discipline.

Consider what happens if four competitors are constantly fighting for market share.

Each has an incentive to offer cheaper plans.

But once two competitors disappear through consolidation, the remaining operators may have less incentive to compete purely on price.

That does not mean prices suddenly jump.

More likely, the market gradually becomes less promotional.

Discounting becomes less aggressive.

ARPU stabilises.

Customer acquisition becomes less expensive.

And the same network infrastructure can generate more revenue.

This is why the potential merger should be viewed as an industry-restructuring event, not simply an M&A transaction.

StarHub is increasingly positioning itself as the natural consolidator

There is an important strategic development that the market should not overlook.

StarHub has been steadily increasing its consumer scale without buying another network operator.

In August, it announced that all MyRepublic 4G subscribers would migrate onto the StarHub network, extending an existing 5G wholesale partnership.

That move has two implications.

First, StarHub gains additional network utilisation and wholesale economics.

Second, it demonstrates that the company is already consolidating customer relationships around its network.

StarHub also describes itself as Singapore’s number-two mobile operator by revenue market share.

That makes an eventual M1 transaction strategically logical.

The resulting business could have greater scale across:

• mobile;
• broadband;
• enterprise connectivity;
• 5G infrastructure;
• wholesale arrangements; and
• consumer brands.

In other words, StarHub does not necessarily need to acquire M1 simply to get bigger. It could acquire M1 to change the economics of the entire mobile business.

The failed Simba-M1 deal actually makes StarHub more interesting

At first glance, the collapse of Simba’s proposed acquisition of M1 looks like bad news for consolidation.

But there is a second interpretation.

The deal demonstrated that M1 has strategic value to potential buyers.

The transaction was ultimately terminated in May 2026 after conditions were not fulfilled or waived by the long-stop date.

The failure also leaves Keppel with an asset it has previously indicated should fit within a broader strategy of portfolio optimisation.

That potentially creates a different negotiating dynamic.

A future buyer is no longer necessarily competing with Simba on the same transaction.

And StarHub has a potentially stronger industrial rationale for acquiring M1 than a financial buyer would.

For StarHub, M1 is not just another telecom asset. It is potentially the missing piece in a domestic network consolidation strategy.

But the deal only works if StarHub does not overpay

This is where investors need to be careful.

A good strategic asset can become a bad investment at the wrong price.

DBS’s July analysis estimated M1 at around S$1.02 billion enterprise value, based on roughly 7–7.5 times estimated FY2026 EBITDA. It estimated around S$70 million of recurring annual synergies.

Those assumptions are important.

If StarHub pays substantially more than the standalone value of M1, it is effectively giving the seller some of the merger benefits.

That would weaken shareholder returns.

The ideal transaction therefore has three components:

reasonable purchase price + credible cost synergies + improving industry pricing.

Take away the first and the deal can destroy value.

Take away the second and it becomes difficult to justify.

Take away the third and investors are left with a larger but still low-growth telco.

StarHub’s balance sheet gives it some ammunition — but not unlimited ammunition

Funding is another important part of the equation.

StarHub’s recent results showed S$874.3 million of revenue excluding Ensign and EBITDA of S$158.6 million for H1 2026. The company also highlighted the Ensign transaction as strengthening its financial flexibility.

Management has indicated an intention to dispose of its remaining Ensign stake by end-2026, potentially creating additional capital for strategic purposes.

That could provide StarHub with greater M&A capacity.

But investors should resist the temptation to treat every dollar of disposal proceeds as “free money”.

Capital used to buy M1 has an opportunity cost.

The company could instead:

• reduce debt;
• increase dividends;
• buy back shares;
• invest in enterprise infrastructure; or
• pursue other growth opportunities.

The correct question is therefore not:

Can StarHub afford M1?

It is:

Will buying M1 generate a higher return than the alternatives available to StarHub?

There is another way the merger could create value: network efficiency

The StarHub-M1 relationship is unusually interesting because the two already share 5G infrastructure through Antina.

That potentially lowers the complexity of network integration.

The industry therefore has an unusual situation where two competitors already cooperate on infrastructure while competing commercially.

A merger could theoretically bring those economics closer together.

Instead of two companies separately optimising commercial operations around shared infrastructure, a combined operator could potentially optimise:

• spectrum utilisation;
• network investment;
• customer acquisition;
• retail distribution;
• back-office systems;
• technology platforms; and
• enterprise sales.

That is why the network-sharing arrangement matters.

The merger is not starting from zero.

There is already an infrastructure relationship that could make some of the economic benefits easier to realise.

The bigger beneficiary may actually be Singtel

There is an important second-order effect here.

Investors might instinctively assume StarHub is the obvious winner from consolidation.

But Singtel could benefit substantially too.

Why?

Because Singtel would remain one of the largest operators in a market with fewer competitors.

If the industry becomes less promotional, Singtel could see its domestic mobile economics stabilise without having to spend capital acquiring another operator.

And Singtel is no longer solely dependent on Singapore consumer telecoms.

Its FY2026 group results show a much broader earnings base, with 85 per cent of proportionate EBITDA coming from outside Singapore and significant contributions from Airtel, AIS, NCS, Digital InfraCo and Optus.

This means Singtel could potentially enjoy the benefits of a more rational Singapore market while continuing to allocate capital toward higher-growth businesses elsewhere.

That may make Singtel a less obvious but potentially important consolidation beneficiary.

Why Simba matters more than its market share suggests

The fourth operator is central to the investment thesis.

If Simba continues competing aggressively on price, a StarHub-M1 merger may not fully solve the industry’s pricing problem.

Three network operators could still compete intensely.

This is why regulatory developments surrounding Simba matter.

The company has been cooperating with IMDA investigations concerning whether it breached telecommunications requirements, while the previous M1 transaction was terminated.

But investors should not build a thesis around regulatory difficulties eliminating Simba.

That would be speculative.

The more durable thesis is different:

Regulatory requirements can gradually reduce the structural cost advantages available to smaller operators.

Cybersecurity, resilience and 5G requirements can increase the cost of operating a network.

If smaller operators face more of the same obligations as incumbents, some of the economic gap could narrow.

That could encourage more rational competition without regulators explicitly forcing a merger.

The bear case: consolidation does not automatically create pricing power

There is a serious counterargument.

Singapore’s telecommunications market is highly regulated.

Competition authorities and regulators have historically placed considerable emphasis on consumer choice.

Even if StarHub and M1 merge, the resulting company cannot simply behave as if it has a monopoly.

Simba remains.

Singtel remains.

MVNOs remain.

And consumers can switch providers relatively easily.

There is therefore no guarantee that consolidation translates into materially higher ARPU.

Another problem is that customers may not be particularly loyal to telecom brands.

If StarHub raises prices while a competitor keeps promotional plans, customers can move.

That limits the amount of pricing power consolidation can generate.

The second bear case: integration could consume the synergies

A merger creates costs before it creates benefits.

Systems must be integrated.

Employees may need to be rationalised.

Retail networks may overlap.

Customer migration can create churn.

Technology platforms need to be combined.

Regulatory approvals can take time.

And the more ambitious the transformation, the longer the payback period.

This is why DBS expects meaningful synergy extraction to be more visible from FY2027 rather than immediately.

For shareholders, patience would therefore be required.

A merger headline could lift StarHub’s share price immediately.

But the real test comes later.

Can management actually convert the promised synergies into recurring free cash flow?

What about StarHub’s non-mobile businesses?

Another reason not to view StarHub purely as a mobile merger play is its enterprise business.

StarHub said its enterprise won orderbook increased by approximately 50 per cent year on year in H1 2026.

This matters because enterprise connectivity and digital infrastructure can provide a different growth path from saturated consumer mobile.

The strategic risk is that investors become so focused on a potential M1 deal that they overlook StarHub’s broader transformation.

The best-case scenario is therefore not:

StarHub + M1 = bigger telco.

It is:

StarHub + M1 = lower-cost network platform + stronger consumer economics + growing enterprise business.

That is a much more compelling investment thesis.

Bull case: consolidation finally changes the industry’s profit pool

The bullish case has four layers.

1. Cost synergies

Duplicated costs can be removed.

2. Network efficiencies

Existing infrastructure-sharing arrangements could make integration more economically attractive.

3. Better ARPU

Reduced competitive intensity could stabilise pricing.

4. Greater scale

The combined company would have greater bargaining power, customer scale and network utilisation.

DBS estimates annual synergies of around S$65–75 million.

If industry ARPU simultaneously stabilises, the earnings upside could be considerably larger than the headline cost savings.

This is why the deal could represent a structural change rather than a financial engineering exercise.

Bear case: StarHub buys a declining asset at the top of the cycle

The bearish scenario is almost the opposite.

StarHub pays too much.

M1’s earnings continue deteriorating.

The cost savings take longer than expected.

ARPU remains under pressure.

Simba continues competing aggressively.

Integration costs rise.

And StarHub ends up with a larger balance sheet but little improvement in return on capital.

That would be a particularly painful outcome because telecom infrastructure requires substantial ongoing investment.

A bigger network is not necessarily a better investment.

Scale only creates value when the incremental customer and network economics improve.

The most important metrics for investors

If StarHub-M1 discussions advance, investors should look beyond the acquisition price.

The following metrics will tell them whether the thesis is actually working:

Of these, ARPU and free cash flow may be the most important.

If ARPU rises but free cash flow does not, the merger is not delivering enough.

If ARPU stabilises and free cash flow rises, the market may finally have evidence that Singapore telecom consolidation is working.

Investment conclusion: StarHub is becoming a consolidation option, but the deal price is everything

The Singapore telco sector has reached an uncomfortable point.

Consumers are benefiting from cheap mobile and broadband services.

But increasingly, shareholders are paying the price.

StarHub’s underlying earnings pressure demonstrates the problem, while Singtel’s Singapore operations are also experiencing weaker domestic economics.

The market therefore has a strong structural reason to consolidate.

But investors should distinguish between a plausible merger and a profitable merger.

For StarHub, an M1 acquisition could be transformative if it delivers three things simultaneously:

lower costs, stronger network economics and a recovery in ARPU.

The first is relatively tangible.

The second is plausible.

The third is the real prize — and the hardest to prove.

That is why I would classify StarHub as a WATCH / SPECULATIVE BUY ON CONSOLIDATION EXECUTION, rather than simply buying the stock because a merger might happen.

The upside is potentially substantial if the market begins to price StarHub as the beneficiary of a structural rationalisation of Singapore’s mobile industry. DBS, for example, has already estimated around S$65–75 million of potential annual synergies from a StarHub-M1 combination.

But investors should demand discipline on valuation and leverage.

The best outcome is not for StarHub to become Singapore’s largest telco.

It is for StarHub to become a more profitable telco.

That distinction will determine whether an M1 acquisition creates shareholder value or simply creates a larger version of today’s problem.

Over the next 12–24 months, the most important signal may therefore not be the announcement of a merger.

It will be something much less exciting:

whether Singapore’s mobile ARPU finally stops falling.

If it does, investors may discover that the real value of StarHub-M1 was never the S$70 million or so of cost savings.

It was the possibility of finally ending a decade-long race to the bottom in Singapore telecom pricing.

And if that happens, Singtel could benefit alongside StarHub — because the biggest winner from consolidation may ultimately be the entire industry’s profit pool.
