Equity Fund Raise · Question

What does dilution mean when a new investor comes in?

Short answer

Dilution is the fall in each existing shareholder's percentage ownership when a company issues new shares to a new investor. Your number of shares stays the same, but the total grows, so your slice of the company is smaller. Whether you are worse off depends on whether the money raised increases the value of the company by more than the share you give up.

In more detail

Picture the company as a cake sliced into shares. When an investor is issued new shares, the cake is cut into more slices. You still hold the same number of slices, but they now represent a smaller fraction of a larger cake. The investor's money, if used well, should make the cake itself larger.

Two figures drive the outcome: the valuation agreed before the investment, often called pre-money, and the amount invested. The investor's stake roughly equals the amount invested divided by the value of the company after the money comes in. A higher agreed valuation means the same cheque buys a smaller stake and dilutes you less.

A simple walk-through

A promoter holds all the shares of a company agreed to be worth a certain amount. An investor puts in a sum equal to a quarter of the value after investment. After the deal, the investor holds a quarter, so the promoter holds three quarters. The promoter owns less in percentage terms but now owns it in a better-funded company.

Dilution also comes from other sources: employee share plans, convertible instruments that later turn into shares, and future rounds. These stack up, so it is wise to model several rounds ahead rather than looking only at the current deal.

Percentage is not the only thing that changes. Control can shift if an investor gains the right to approve key decisions or if your stake falls below levels at which certain resolutions can be passed. Check the shareholders agreement and company law thresholds with an adviser.

Dilution is not a loss in itself. Owners who refuse every form of dilution may miss growth that would have raised the value of their remaining stake. The real question is the price paid for the capital and what it is used for.

Key points

Dilution reduces your percentage when new shares are issued, not your share count.
A smaller share of a more valuable company can be worth more than before.
Higher valuation at the time of investment means less dilution for the same money.
Option plans and convertibles add further dilution that should be modelled.
Watch control thresholds and investor consent rights as your percentage falls.
