Short answerA mid-market private sale in Singapore usually needs about four to six weeks to prepare the room and six to ten weeks of due diligence before signing. An SGX Mainboard listing takes much longer. Add a CCCS review if market shares are near the guides.

How it works

The estimate adds room preparation, due diligence and any regulatory review. Preparation grows when records are scattered; due diligence grows with the number of bidders because Q&A volume rises.

CCCS reviews are counted in working days: about six weeks for Phase 1 and around six months if a Phase 2 review follows. Public holidays such as Chinese New Year and Hari Raya, and year-end audits, often add a week or two in practice.

Questions people ask

How long does due diligence take in Singapore?

For a typical mid-market private deal, six to ten weeks after the room opens. Small business sales can be done in three to four weeks; IPOs take several months.

What slows a Singapore deal down?

Disorganised records, unanswered Q&A, missing corporate resolutions, regional subsidiaries with records in other languages, and regulatory reviews.

When should the data room be ready?

Before the first bidders are invited. Opening a half-empty room sends a poor signal and creates a flood of requests.
