A potential merger between StarHub and M1 would create a stronger challenger to Singtel in Singapore's mobile market, but would likely come at the cost of consumer perks, according to analysts cited by CNA.

The assessment lands on a market that has spent years defined by fierce price competition among three full-service operators plus a fourth entrant. StarHub and M1, the second- and third-largest traditional players by subscriber base, have both spent much of the past decade competing on aggressive data bundles, promotional pricing and handset subsidies. Consolidation would end the head-to-head rivalry between two of the three incumbents.

What would the merger change competitively?

The core of the analyst argument is straightforward arithmetic. Combining StarHub's and M1's mobile customer bases into a single entity would produce an operator with scale approaching Singtel's local mobile business, rather than two smaller players each fighting the market leader separately.

That scale matters in several concrete ways:

• Combined network and spectrum holdings across the merged entity's footprint
• Greater negotiating leverage with equipment vendors and handset suppliers
• A single balance sheet better able to fund 5G rollout and network upgrades
• Reduced duplication of capital expenditure on overlapping infrastructure

Singapore's regulators structured the 5G era around competition. At the 2019 spectrum awards, the Infocomm Media Development Authority (IMDA) designated two 3.5GHz licence winners — Singtel through a consortium, and a StarHub-M1 joint venture — precisely so that no single operator would dominate the mid-band 5G band. A full corporate merger of StarHub and M1 would collapse that jointly held 5G position into one entity, tightening the structure the regulator originally engineered.

Why would consumers lose out?

The second half of the analysts' warning is the mirror image of the first. The same consolidation that strengthens the merged company's competitive position weakens the pressure that keeps prices and perks generous.

With one fewer independent national operator bidding for subscribers, the incentives shrink for:

• Aggressive promotional data bundles and price plans
• Generous handset subsidies and trade-in offers
• Loyalty rewards and retention offers
• Frequent plan refreshes aimed at poaching rivals' customers

Singapore's mobile users have benefited from years of this competition, particularly after the 2016 entry of TPG Telecom as a fourth player triggered a round of price cuts and larger data allowances across the market. Removing one competitor from that equation would, on the analysts' reading, unwind some of those gains.

What happens next?

No merger has been announced. The discussion remains at the level of analyst speculation about a potential transaction, not a confirmed corporate action by either StarHub or M1's ownership.

Any actual deal would face scrutiny from Singapore's competition and telecoms authorities, who would have to weigh the competition concerns against any efficiency or network-investment commitments the merging parties offered. How IMDA and the Competition and Consumer Commission of Singapore would treat a market going from three full-service mobile operators to two is the question that would ultimately determine whether such a merger could proceed, and on what conditions.
