Definition

Dilution is the decrease in existing shareholders’ ownership percentage of a company that occurs when the company issues additional shares. This can happen through the conversion of convertible securities, the exercise of stock options or warrants, or issuing new shares. The result is a reduction in earnings per share (EPS) and book value per share as the number of outstanding shares increases.

Examples

  1. Convertible Securities:

    • A company issues 1,000 convertible bonds, each convertible into 10 shares of common stock. If all the bonds are converted, an additional 10,000 shares are issued, diluting the ownership and EPS of existing shareholders.

  2. Stock Options:

    • Employees hold options to purchase 5,000 shares. When exercised, the company’s total number of shares outstanding increases, diluting the value and EPS of existing shares.

  3. Warrants:

    • A company issues 3,000 warrants, with each warrant convertible into one share of common stock. If all warrants are exercised, 3,000 new shares are added to the share pool.

Frequently Asked Questions

Q1: What is the impact of dilution on earnings per share (EPS)?

  • A1: Dilution reduces EPS since the same level of earnings is now spread across a greater number of shares.

Q2: How does dilution affect book value per share?

  • A2: Book value per share declines because the company’s total equity value remains the same while the number of outstanding shares increases.

Q3: What are fully diluted earnings per share?

  • A3: Fully diluted EPS is calculated assuming all convertible securities, warrants, and stock options are converted into common stock. It provides a worst-case scenario for dilution.

Q4: Can dilution be beneficial at any time?

  • A4: Dilution can be beneficial if the capital raised is used in a way that significantly increases the company’s profitability and overall value.

Q5: How do companies report potential dilution?

  • A5: Companies report potential dilution in their financial statements typically through the calculation of diluted EPS.

  • Earnings Per Share (EPS): A company’s profit divided by its number of outstanding shares. It indicates the company’s profitability per share of stock.

  • Book Value Per Share: A measure of the book value of a company expressed on a per-share basis. Calculated as total equity divided by the number of outstanding shares.

  • Fully Diluted Earnings Per (Common) Share: Earnings per share calculated considering all possible shares that could be created from convertible securities, stock options, warrants, etc. being converted to common stock.
