Singapore Updates Merger Control Regime—What Dealmakers Need To Know

On 7 April 2026, the Competition and Consumer Commission of Singapore ("CCS") unveiled revised Guidelines on Merger Procedures, an updated merger filing form ("Form M1"), and consequential amendments to its Guidelines on Directions and Remedies. The changes—which take effect on 1 May 2026—follow a public consultation last autumn and represent the most significant overhaul of Singapore's merger control framework in recent years.

The regulator's clear objective: a faster, more efficient, and more predictable merger review process.

Three headline changes stand out:

• A new fast-track for low-risk deals. The CCS has introduced a streamlined review track for mergers unlikely to raise competition concerns. Phase 1 timelines drop from 30 to 25 working days—a meaningful acceleration for time-sensitive transactions.
• Less paperwork, earlier signals. Revised guidelines and a slimmed-down Form M1 reduce information requirements for both merger parties and third parties. The CCS also commits to providing earlier indications on whether a transaction may face scrutiny—helping deal teams plan accordingly.
• Structured pre-notification engagement. The new Form M1 includes a courtesy call template, encouraging parties to submit structured transaction summaries before formal filing. This should facilitate more focused and efficient early-stage discussions with the regulator.

What This Means for Dealmakers

For businesses and advisers active in the Singapore market, these reforms offer tangible benefits:

• Tighter deal timetables. The shorter Phase 1 window (25 working days) should improve deal certainty and reduce execution risk for straightforward mergers.
• Lower filing costs. Refined information requirements mean less time spent gathering data and liaising with the regulator—particularly for non-contentious transactions.
• Better visibility on timing. Earlier signals from the CCS on likely outcomes will help deal teams manage signing-to-closing risk and coordinate multijurisdictional filings more effectively.
• Action item: M&A teams and their advisers should familiarise themselves with the revised Form M1 and updated Guidelines before 1 May 2026. Transactions notified on or after that date must use the new form.
