Option Overhang
In briefOption overhang is the pool of outstanding options and conversion rights whose exercise increases the share count. It measures the latent dilution potential beyond the existing shares and is an important warning sign of future dilution for small caps with option-heavy compensation.
Definition
Option overhang refers to the pool of outstanding stock options, conversion rights and share-based compensation whose future exercise can increase the share count. It quantifies the latent dilution potential beyond the currently outstanding shares. It is usually stated as the share of potential new shares relative to the existing ones.
How it is calculated
Formula. potential new shares from options and conversion rights ÷ outstanding shares × 100%
Why it matters for small caps
For capital-scarce small caps, option programs often replace cash compensation, so a high option overhang can considerably increase the future dilution of existing shareholders.
Common misreadings
- Option overhang is ignored because only undiluted EPS is considered and the latent increase in shares is left out.
In the process
Frequently asked
Where can I find the option overhang?
In the notes to the financial statements under share-based compensation and in disclosures on convertible bonds and contingent capital.
At what point is the overhang critical?
The higher the share of potential new shares, the stronger the possible dilution; there are no fixed thresholds, but double-digit values warrant attention.
What is the difference from realized dilution?
The overhang is latent and only occurs upon exercise; realized dilution is already included in the share count.
