Dilution

Dilution is when the ownership percentage of existing shareholders in a company decreases because new shares are issued.

What it means

Imagine a company as a pie divided into slices. Each slice represents a share of the company.

When the company issues more shares, it's like cutting the pie into more slices. Each person's slice becomes smaller if they don't buy more of the new slices.

This means their ownership part of the company decreases in size. Dilution can happen when a company raises more money by selling additional shares.

It might also occur when employees or investors convert their stock options or warrants into shares. While dilution reduces each shareholder's ownership percentage, the money raised through issuing new shares can help the company grow.

In practice

Real-world examples.

1

Example

Imagine you're an entrepreneur who owns 50% of your startup with 100 shares. If you issue 100 more shares to a new investor, your ownership drops to 25% because there are now 200 shares in total.

2

Example

A small business with 1,000 shares decides to issue 500 new shares to raise funds for expansion. The original owners now own a smaller percentage of the business, as the total number of shares has increased to 1,500.

Think of it

Think of a group of friends sharing a pizza. If more friends join and you have to cut the pizza into more slices, each friend gets a smaller piece.
