The IPO timeline: what happens and when

The IPO timeline: what happens and when

Every listing is different in the detail, but most follow the same broad sequence. Knowing the stages, and where the delays usually come from, helps a board plan realistically and keep the process on track.

1. Preparation

Before any formal work begins, the company gets itself ready: audited accounts in order, a board with the right mix of experience, governance that will stand up to public scrutiny, and a clear equity story. This stage is often the longest, and the one most companies underestimate.

2. Appointing advisers

The company appoints its key advisers. Depending on the market this typically includes a nominated or sponsoring adviser, a broker, lawyers and reporting accountants. The adviser team shapes everything that follows.

3. Due diligence

The advisers examine the business in detail: financial, legal and commercial. The reporting accountants review the numbers, the lawyers review contracts, title and disputes. Issues found here need to be resolved before the company can list.

4. The admission document or prospectus

The company, with its advisers, prepares the document that will be published to investors. It describes the business, its risks, its financial history and the terms of the offer. Drafting and verifying it takes several rounds.

5. Marketing and pricing

The broker introduces the company to investors, gauges demand and helps set the price. Management presents the equity story in meetings. Demand at this stage determines how much can be raised and at what price.

6. Admission and first day of trading

The document is published, the shares are admitted to the market and trading begins. The company is now public, with ongoing obligations to report and disclose.

Where the delays come from

Delays almost always come from the early stages: accounts that are not audit-ready, governance gaps, or problems found in due diligence. Market conditions can also shift the timetable at the pricing stage.

The companies that list most smoothly are those that do the preparation work well before they appoint advisers.
