Why the S$1.43 Billion Simba–M1 Deal Collapsed—and What Happens Next

The long-stop date had already been extended to 21 May 2026 while IMDA reviewed the proposed consolidation. Once the regulator paused that review, there was no clear path to completing the deal on time.

The original transaction covered M1’s telecommunications business, while Keppel planned to retain M1’s ICT business. The proposed sale was announced in August 2025 at an enterprise value of S$1.43 billion, with Keppel expecting close to S$1 billion in cash proceeds for its effective stake.

What triggered IMDA’s investigation

IMDA was reviewing the proposed consolidation under Singapore’s telecom and media competition framework. During that process, it learned that Simba could have been using radio-frequency bands that had not been assigned to it to provide mobile services.

Using spectrum outside an operator’s assigned bands without prior approval would breach the Telecommunications Act 1999 and the conditions of Simba’s Facilities-Based Operations licence, according to reporting on IMDA’s position.

The issue is significant beyond the merger itself. Singapore’s Ministry of Digital Development and Information said mobile network operators must use only spectrum assigned to them, because unauthorised use can cause interference and potentially give an operator an unfair competitive advantage.

IMDA therefore suspended its merger assessment until further notice, saying the investigation’s findings could be material to its decision on the proposed consolidation. The suspension was not a finding that Simba had breached the rules: the regulator was still investigating the allegation.

What penalties could Simba face?

If the alleged spectrum breach is established, IMDA has said it will take appropriate enforcement action. The legal material provided identifies possible powers to impose a financial penalty of up to S$1 million and to suspend or cancel all or part of the relevant spectrum right.

Those are potential consequences, not penalties that had been imposed at the time the merger review was suspended. The available reporting does not establish the investigation’s final findings or a confirmed enforcement outcome.

What happens to M1 now?

Keppel has activated a “Plan B” focused on improving M1’s operating performance while it retains majority ownership. The initial programme is designed to improve M1’s run-rate EBITDA through:

• structural rightsizing;
• AI-led automation;
• lower technology-platform costs;
• lower network costs; and
• product rationalisation.

Keppel described the programme as a 90-day effort to strengthen M1’s competitiveness while maintaining customer experience.

Keppel later set a target of S$70 million in annual cost savings by 2028. It reported that the measures introduced so far were expected to deliver S$4 million in annual savings initially, with yearly savings targeted to reach S$10 million by the end of 2026.

The company has not immediately relaunched the sale process. Its stated approach was to improve M1 first and re-engage potential buyers in roughly 12 to 18 months.

Could Simba still be involved in a future consolidation?

The failed transaction does not necessarily end the possibility of consolidation in Singapore’s telecom market. Keppel has not ruled out a future deal involving Simba, but any later proposal would be a separate transaction and would again require regulatory review and approval.

That distinction matters: the original agreement has ended, and a future approach would have to be assessed in light of any findings from the spectrum investigation as well as competition and public-interest considerations.

What could the changes mean for M1 employees?

Keppel has not promised that the efficiency programme will avoid job losses. Its use of terms such as “rightsizing” and automation indicates that workforce structure is part of the cost-reduction plan, but no confirmed number of redundancies was announced in the available evidence.

Unionised employees would need to be handled through the relevant collective-agreement and consultation processes. That does not establish a specific redundancy plan; it only sets the process that would apply if workforce changes are proposed.

M1 had about 1,300 employees and roughly two million mobile subscribers at the time. The scale of the workforce and customer base explains why Keppel said the restructuring would need to balance cost reductions with service quality.

The bottom line

The Simba–M1 deal failed because a regulatory investigation interrupted IMDA’s review just days before the contractual deadline. Keppel decided that allowing the agreement to lapse was more practical than extending it again, leaving M1 under its control and shifting the immediate focus from a sale to operational restructuring.

The next milestones are the outcome of IMDA’s spectrum investigation, the progress of M1’s efficiency programme, and whether Keppel can attract new buyers after improving the business. A future consolidation involving Simba remains possible in principle, but it would face fresh regulatory scrutiny.
