What it means
An initial public offering gets a company onto the market, but it is rarely the last time shares are sold. A follow-on offering is any subsequent sale of shares by an already-listed business, and for many companies it is a routine part of funding growth.
In a primary follow-on, the company creates new shares and receives the proceeds. Total share count rises, so each existing share represents a slightly smaller slice of the company, which is dilution in its plainest form.
In a secondary follow-on, no new shares exist. A founder, a venture fund or an early employee simply sells shares they already own, so the company's share count and balance sheet are unchanged even though the market sees a large block of stock change hands.
The market usually reads the two very differently. A primary raise funding an acquisition or a new plant can be taken positively, while a large insider sale often reads as a signal about how those insiders view the price, so share prices frequently dip on announcement.
Mechanically, a follow-on looks much like an initial public offering but faster and cheaper. There is already a market price to anchor the deal, disclosure documents are shorter, and underwriting fees are typically lower because the risk of mispricing is smaller.
Shares are usually priced at a modest discount to the market price to attract buyers for the large block. That discount, plus the underwriting fee, is the real cost to existing shareholders of raising the money this way.
In practice
Real-world examples.
Example
A renewable energy developer with a large pipeline raises $150,000,000 in a primary follow-on to fund three solar farms. Because investors can see the specific projects, the share price holds steady despite the new shares.
Example
Two founders of a listed consumer brand sell 8,000,000 of their own shares in a secondary follow-on to diversify their personal wealth. The company receives nothing and share count is unchanged, but the stock falls 6% on the day as the market digests the insider sale.
Example
A regional bank issues new shares in a follow-on to meet a tightened capital requirement. Existing shareholders are diluted, but the alternative was shrinking the loan book, so the board judges dilution the cheaper outcome.
Formula
Calculation
Net proceeds = New shares x Offer price x (1 - Underwriting fee rate)
Diluted EPS = Total earnings / (Existing shares + New shares)
A listed logistics company has 20,000,000 shares outstanding and earnings of $40,000,000. It issues 5,000,000 new shares at $18 each in a primary follow-on offering, with underwriting fees of 5%.
Gross proceeds = 5,000,000 x $18 = $90,000,000
Underwriting fee = $90,000,000 x 5% = $4,500,000
Net proceeds = $90,000,000 - $4,500,000 = $85,500,000
Earnings per share before = $40,000,000 / 20,000,000 = $2.00
Shares after the offering = 20,000,000 + 5,000,000 = 25,000,000
Earnings per share after = $40,000,000 / 25,000,000 = $1.60
An investor who held 200,000 shares owned 1.0% of the company before the deal and 0.8% afterwards, since 200,000 divided by 25,000,000 is 0.8%. Earnings per share fell 20%, so the $85,500,000 raised must eventually generate at least $10,000,000 of extra profit just to restore the original $2.00.Case study
Seen in the real world.
Verrow Diagnostics is an invented company used here as an illustrative example of how a follow-on offering plays out. Three years after listing, it had a working product and a large order book but not enough manufacturing capacity, and building a second facility needed $60,000,000 it did not have.
The board considered debt but the business was not yet reliably cash generative, so it chose a primary follow-on. With 30,000,000 shares trading at $22, it issued 3,000,000 new shares at a discounted $20.50, raising $61,500,000 gross and about $58,400,000 after fees, while diluting existing holders by roughly 9%.
The fictional outcome is instructive rather than triumphant. Capacity doubled and revenue followed, but earnings per share took seven quarters to return to the pre-offering level, which is the pattern management teams routinely underestimate when they present a raise as a straightforward win.
Watch out
Common mistakes.
- Assuming every follow-on offering brings money into the company. Only a primary offering does, since a secondary offering simply transfers existing shares from one owner to another.
- Reading a share price fall on announcement as proof the deal was bad. Some fall is normal because new shares are priced at a discount and supply has temporarily increased.
- Ignoring the earnings per share effect. Raising money is only worthwhile if the new capital eventually earns more than the return implied by the shares given up.
Questions
People also ask.
How is a follow-on offering different from an initial public offering?
An initial public offering is the first sale of shares to the public, while a follow-on happens after the company is already listed and generally costs less to execute.
Does a follow-on always dilute existing shareholders?
Only a primary offering does, and even then holders who buy their proportionate share of the new stock can keep their percentage intact.
Why are follow-on shares sold at a discount?
Because placing a large block quickly requires an incentive for buyers, and the discount compensates them for taking on that volume.
