Warrant overhang
Also called: overhang, warrant coverage
The block of shares that could be created if a company's outstanding warrants are exercised. It is potential dilution that does not yet appear in the shares outstanding figure.

What it means
A warrant is a contract that lets its holder buy newly issued shares from the company at a fixed exercise price until an expiry date. Warrants are often handed out alongside shares in a financing as a sweetener. Until they are exercised, they add nothing to the share count. Once exercised, every warrant becomes a new share, and the company receives the exercise price in cash.
The total number of shares those warrants could become is the overhang. The term is used loosely for any unexercised securities that can turn into common stock, but it most often refers to warrants.
Why it matters
- It is dilution waiting in the wings. The fully diluted share count, which includes warrants, can be far larger than the basic count on a quote page.
- The exercise price is a reference point. Warrants are generally only worth exercising when the stock trades above the exercise price, so traders note where those prices sit relative to the current price.
- Terms vary. Some warrants can be exercised on a cashless basis, some have price adjustment clauses that lower the exercise price after later financings, and some can be called by the company. The terms are in the warrant agreement, usually filed as an exhibit.
Worked example
Hypothetical: Company X has 60,000,000 shares outstanding and 8,000,000 warrants with a $3.00 exercise price. If all are exercised, the count becomes 68,000,000, a 13% increase, and the company receives $24,000,000. If the stock trades at $2.00, exercising would mean paying $3.00 for a share worth $2.00, so holders generally wait.
Warrants are one input; an ATM offering is another common source of new shares.
