The immediate trigger was regulatory, not financial.
During its review of the proposed merger, IMDA said it discovered that Simba may have used radio‑frequency bands that were not assigned to it for mobile services. The regulator suspended its evaluation of the merger pending further investigation and said enforcement action could follow if violations are confirmed.
Because the regulatory review could not proceed, Keppel—the majority owner of M1—decided to allow the transaction to lapse at its contractual long‑stop date on May 21 rather than wait indefinitely for a resolution.
The merger had originally been announced in August 2025 as part of Keppel’s strategy to divest M1’s telecom business, with the deal valuing the operator at about S$1.43 billion.
With the merger abandoned, Singapore’s market structure remains unchanged: four nationwide mobile operators competing in a small and highly saturated market.
This structure has long fueled aggressive price competition. Analysts widely expect that consumers will continue benefiting from low prices and frequent promotions while four operators compete for subscribers.
But the same competition has also compressed profitability across the industry. Smaller operators in particular face pressure to balance:
These economics are a key reason consolidation has repeatedly been discussed as a potential long‑term solution.
For mobile users, the immediate effects are likely positive.
Keeping four operators instead of three preserves intense price competition, which typically translates into cheaper plans and more promotional offers.
However, the longer‑term trade‑off could involve investment incentives. Telecom networks require large and continuous spending—especially for 5G capacity and infrastructure. If profitability remains constrained across the sector, operators may respond by:
That dynamic creates a familiar telecom policy tension: lower prices today versus sustained infrastructure investment tomorrow.
With the sale abandoned, Keppel has activated a contingency plan to improve M1’s performance as a standalone business.
The company said it will execute a 90‑day restructuring programme focused on boosting efficiency and improving run‑rate EBITDA while maintaining service quality.
The plan includes several operational changes:
The goal is to make M1 leaner and more cash‑generative without relying on merger‑driven scale to improve economics.
Simba also faces significant challenges as a standalone operator.
First, the ongoing regulatory investigation into its spectrum use remains an overhang for the company and could potentially lead to enforcement action depending on the findings.
Second, the company operates with relatively low revenue per user. According to Tuas Limited—the Australian‑listed parent company—Simba’s gross mobile ARPU was S$9.61 in the first half of FY2026, essentially unchanged from S$9.60 a year earlier.
Low ARPU makes it difficult to fund ongoing network expansion. Even as a standalone operator, Simba expects S$50 million to S$55 million in mobile and broadband capital expenditure while continuing to expand its network capacity.
The company has reported that it exceeded its 5G coverage obligations ahead of the December 2026 milestone, but sustaining network performance and monetising that infrastructure remain ongoing challenges.
Despite the failed deal, many industry leaders still believe consolidation in Singapore’s telecom market may ultimately be unavoidable.
The fundamental economics have not changed:
Keppel has said the sector would benefit from consolidation, and Singtel’s leadership has already sought clarification from regulators on whether it could participate in future telecom mergers.
In other words, the strategic rationale behind the Simba–M1 deal remains intact—even if the specific transaction failed.
Several developments will determine the next phase of Singapore’s telecom industry:
1. IMDA’s investigation outcome
The regulator’s findings on Simba’s spectrum use could influence both enforcement action and the regulatory environment for future mergers.
2. M1’s restructuring progress
Keppel’s 90‑day transformation plan will reveal whether M1 can improve profitability without consolidation.
3. Future consolidation attempts
Operators and regulators will continue debating whether Singapore’s market structure should remain a four‑player ecosystem or eventually move toward three.
For now, the collapse of the Simba–M1 deal keeps Singapore’s telecom market exactly where it has been for years: highly competitive, consumer‑friendly on prices, and structurally challenging for operators trying to earn sustainable returns.
