What decision this helps you make: Whether a share issuance helps or harms the holders who do not participate — and, if you are the issuer, which structure to use.

What this topic is

A follow-on offering is a public company selling stock after its listing. If the company issues new shares, it raises money and the share count grows. If existing holders sell their own shares, the company raises nothing and the count does not change. The two are routinely called the same thing, and they are opposite transactions.

Why it matters

Issuance is how listed companies fund growth, repair balance sheets and survive downturns. It is also the mechanism by which shareholders are quietly transferred value — through the discount, the fees, and the use of the proceeds. Knowing which is happening is the difference between a rational reaction and a reflex.

Who should learn it

Investors reading an offering announcement, executives and boards deciding how to raise equity, and anyone who has watched a stock fall on a capital raise and assumed the fall was the dilution.

What you will understand

  • The real difference between a secondary sale and a primary issuance
  • Four issuance structures and what each trades away
  • The arithmetic of ownership, earnings and value dilution — which differ
  • Why a rights issue leaves a participating holder exactly whole

Prerequisites

Common misconception

"Issuing shares dilutes existing holders." Only if the shares are sold below what they are worth, or the money is deployed below the cost of capital. Sell new stock at fair value and pro-rata ownership falls while value per share is unchanged — the holder owns a smaller slice of a proportionally larger pie. Sell it above fair value and remaining holders are made better off. The damage in a real offering comes from the discount and the fees, which are usually a small single-digit percentage, not from the share count, which is often the number everyone quotes.
