What it means
A flotation is a fundraising event and a change of legal status at the same time. New shares issued at the offer price bring cash into the company, whereas shares sold by founders or early investors bring cash to those individuals instead.
Most offers mix the two, and the split matters to buyers because money going to selling shareholders does not fund future growth. Getting to a listing takes months of preparation and a small army of advisers.
Accountants prepare audited historic figures, lawyers draft the prospectus, and the sponsoring bank builds a book of institutional demand across a range of prices. The final price is struck where the book is comfortably covered, usually with a deliberate discount so the shares trade up on the first day.
The costs are substantial and often understated in internal business cases. Underwriting commission commonly runs somewhere around 3% to 7% of the money raised, on top of legal, accounting, registrar, exchange and marketing fees that can add several million dollars on a mid-size deal.
Ongoing listed-company costs for reporting, investor relations and additional governance then continue every year afterwards. The benefits are real but conditional rather than automatic.
A listing gives access to public equity for future fundraising, a traded currency for making acquisitions, an exit route for early backers and a visible market valuation. Those benefits only materialise if the company is large enough and interesting enough to attract genuine research coverage and steady trading volume.
Flotation is also not the only route onto an exchange. A direct listing places existing shares on the market without raising new money or using underwriters, while a reverse takeover puts a private business inside an already-listed shell company.
Each avoids some flotation costs but gives up the price discovery and demand-building that a properly bookbuilt offer provides.
In practice
Real-world examples.
Example
A family-owned engineering group floats 30% of its equity to fund two acquisitions and give a retiring founder an exit. Roughly 60% of the proceeds go to the company and 40% to the selling founder, a split the prospectus discloses clearly because institutional buyers scrutinise it closely.
Example
A software business abandons its flotation two weeks before pricing when demand comes in below the bottom of the range. It has already spent about $4,000,000 on advisers, none of which is recoverable, and it raises a private round instead at a lower valuation.
Example
A mining company lists on a smaller growth market with a free float of just 18%. Trading volume never develops, only one broker covers the stock, and four years later the board takes the company private again, concluding that the listing cost more in fees and management time than it delivered.
Formula
Calculation
Gross Proceeds = New Shares Issued x Offer Price
Net Proceeds = Gross Proceeds - Underwriting Fee - Other Costs
Free Float % = Shares Sold to the Public / Total Shares After the Offer
Larkhill Systems has 30,000,000 shares held privately and decides to float. It issues 10,000,000 new shares at an offer price of $12.00, so gross proceeds are 10,000,000 x $12.00 = $120,000,000.
Underwriting commission is 5% of gross proceeds, or 0.05 x $120,000,000 = $6,000,000, and legal, accounting, registrar, exchange and marketing costs add a further $3,500,000. Total issue costs are $6,000,000 + $3,500,000 = $9,500,000, so net proceeds to the company are $120,000,000 - $9,500,000 = $110,500,000. The all-in cost of the flotation is $9,500,000 / $120,000,000 = 7.9% of the money raised.
After the offer Larkhill has 30,000,000 + 10,000,000 = 40,000,000 shares in issue, valuing the company at 40,000,000 x $12.00 = $480,000,000 at the offer price, with a free float of 10,000,000 / 40,000,000 = 25%. If the shares close their first day at $14.40, that is a 20% first-day rise, and the "money left on the table" is 10,000,000 x ($14.40 - $12.00) = $24,000,000, being value that went to new investors rather than to the company.Case study
Seen in the real world.
The following is an illustrative and fictional example. Danesfield Health Group, an invented operator of outpatient clinics, floated after eight years as a private business. It issued 12,000,000 new shares at $15.00, raising $180,000,000 gross, and its founders sold a further 4,000,000 existing shares into the same offer.
Issue costs came to $13,600,000, roughly 7.6% of the $180,000,000 of new money raised, leaving Danesfield with $166,400,000 of net new capital for its clinic rollout. The shares rose 14% on the first day of trading, which the sponsoring bank presented as a strong debut and one large existing shareholder privately described as leaving money behind.
Two years later the picture was mixed in a way the illustrative example is meant to highlight. The new capital funded eleven additional clinics and revenue nearly doubled, but the listed-company overhead ran at about $2,400,000 a year and the chief executive estimated she spent a fifth of her time on investor relations. Flotation had bought Danesfield growth capital at the price of permanent public scrutiny.
Watch out
Common mistakes.
- Assuming all the money raised goes to the company. Where existing shareholders sell into the offer, that portion of the proceeds goes to them personally and never touches the business.
- Budgeting only the underwriting fee. Legal, accounting, registrar, exchange, printing and marketing costs frequently add another 2% to 4% of the amount raised, and annual listed-company costs continue indefinitely.
- Treating a large first-day price rise as an unqualified success. A big pop means the shares were priced too cheaply, and every dollar of that rise is capital the company could have raised but did not.
Questions
People also ask.
What is the difference between a flotation and an IPO?
None in substance. Flotation is the more common term in the United Kingdom and Commonwealth markets, while initial public offering is standard in the United States.
How much of a company usually floats?
Free floats commonly land somewhere between 25% and 40% at listing, since most exchanges impose a minimum and institutional investors want enough liquidity to trade meaningfully.
What is a lock-up period?
It is a contractual commitment, typically 90 to 180 days, during which founders, management and pre-listing investors agree not to sell further shares, giving the new market time to settle.
