Initial public offering (IPO)

An IPO (initial public offering) is the first time a business raises finance publicly. Before that, it can only use private investment.

Going public allows your business to raise large sums of money from new investors. Because there are lots of investors with a small percentage of ownership, but no majority stakeholders, you can retain control of the business.

An IPO is sometimes referred to as either ‘listing’ or ‘floating’ on the public market. In the UK, public markets (see below) sit within the London Stock Exchange.

This method is often called ‘long-term capital’ or ‘patient capital’, as businesses can use it to raise money time and time again, over years and even decades.

Once your business is a public company, you have to regularly disclose financial information. You must update shareholders and the market with half-yearly and annual results.

What are the different IPO markets?

• Main Market – for larger businesses; home of FTSE 100 and 250
• High Growth Segment – for tech-specific businesses not quite ready for the Main Market
• AIM – for smaller, growing businesses looking to scale

The AIM market is the world’s most successful growth marketLink opens in a new window, so it’s suited to smaller businesses that are looking to grow. AIM has less prescriptive rules than the Main Markets to make sure that businesses can go public and raise finance as easily as possible.

Nominated adviser or sponsor

Your nominated adviser (often called a ‘Nomad’) on AIM, or your sponsor on the Main Market, helps prepare and admit your company to the public markets.

Broker

Manages your fundraising activity on the market.

Accountant

Responsible for detailed financial reporting.

Law firm

Performs due diligence and oversees the listing from a legal perspective.

Registrar

Manages the register of your shareholders.

Financial PR firm

Helps craft your story and maintains media interest in your company.

Long-term finance

It’s easy to raise more money once you’ve listed your business, without having to go through the process again.

Retain control

On AIM, there’s no minimum ‘free float’ criteria (the percentage of the business put on the market). You’ll be notified if one investor tries to buy beyond your pre-set threshold.

This can help boost sales.

Gives staff an incentive

With employee share options.

Secondary market for shares

This allows existing investors to exit.

No guaranteed return

You may not achieve the valuation you had hoped for.

Costs

What do you look for in a business?

Management and track record

Have you:

• done this before?
• had success in public or private markets?
• grown a business?
• done it well?

Financial profile

Is your product commercially viable? Can you prove it? Are you profitable? How much profit?

Scalability and opportunity

Time

An IPO can take months and sometimes years, so take your time when choosing business advisers. They’ll be with you for the duration of your life as a public company.

People

The IPO process will absorb your CEO and finance director for at least six months. The director team will need to keep the business running in the meantime.

Life as a public company

Once you’ve successfully listed, you’ll need to comply with transparency and disclosure rules. This means you must disclose business information like company wages, finances and tax.

Ongoing costs

You’ll need to retain your Nomad, broker, law firm and PR agency for as long as your business is on the market. As a result, you should factor in these fees when determining your outgoings.

lPOs are often years in the making — and there’s lots of planning to do upfront. Once everything is in place, the process takes between 10–12 weeks.
