What Is Dilution?

Dilution is a term used in finance to describe the reduction in existing shareholders' ownership percentages in a company due to the issuance of new shares. This phenomenon can occur for various reasons, such as a company raising additional equity capital or when employees exercise stock options. When the total number of shares outstanding increases, each existing shareholder's ownership stake is diminished, ultimately affecting the share's value.

The Basics of Shares

A share represents an ownership interest in a company. When a company goes public through an Initial Public Offering (IPO), it issues a certain number of shares, also referred to as the "float." If the company chooses to issue additional shares later, typically in a secondary offering, it effectively increases the float. This leads to dilution of the existing shares, meaning that shareholders who purchased stock during the IPO now own a smaller proportion of the firm than they did before the new shares were issued.

Key Takeaways

Understanding Dilution

You can think about dilution as cutting a cake into more pieces. While there may now be more pieces available, each individual piece is smaller. Similarly, while shareholders retain ownership, their percentage of ownership dilutes as more shares are issued.

The impact of dilution goes beyond simply ownership percentages; it also affects the company's earnings per share (EPS). EPS is calculated by dividing net income by the total number of outstanding shares. When new shares are added, the denominator increases, often leading to a decline in EPS. Many companies provide both non-diluted and diluted EPS figures to give investors insight into potential impacts of dilution on their investments.

Why Do Companies Issue New Shares?

Companies often resort to issuing new shares to raise capital for various reasons, including:

While these actions may ultimately enhance the firm's value, existing shareholders are often the ones bearing the cost of dilution.

Examples of Dilution

General Example

A simple illustration can clarify how dilution works. Imagine a company with 100 issued shares held by 100 shareholders, each owning 1% of the company. If the company subsequently issues another 100 shares to new investors, the total outstanding shares rise to 200. This means each existing shareholder now owns only 0.5% of the company, effectively reducing their influence and voting power.

Real-World Example

Real-world scenarios help substantiate the principles of dilution. A notable example is MGT Capital, which in July 2016, filed a proxy statement outlining a stock option plan for their new CEO, John McAfee. Simultaneously, the company planned to finance acquisitions through stock and outlined proposals for additional share issuance. This advance notice allowed investors to understand the looming dilution and to plan their investments accordingly.

Dilution Protection

Given the negative implications of dilution on existing shareholders, dilution protection provisions are often included in investment agreements. These provisions can protect investors from experiencing significant declines in their ownership percentage during subsequent funding rounds.

How Does It Work?

Such protections are typical in venture capital agreements and are often referred to as "anti-dilution provisions." These clauses can also be a part of convertible securities, safeguarding investors from dilution that arises from new stock issues at prices lower than what they originally paid.

Conclusion

While dilution can provide a company with much-needed capital for growth or debt reduction, it can also significantly impact existing shareholders. Understanding the mechanics of dilution, its implications, and the protections that can be put in place is crucial for investors aiming to make informed decisions in the ever-evolving landscape of corporate finance. Being aware of dilution not only protects investments but also allows shareholders to participate effectively in a company's growth journey.
