What is an Equity Warrant?

What is an equity warrant?

A warrant is the right to purchase or sell something at a specified price. The most common type of warrant in venture finance is an equity warrant (also known as a stock warrant) granted to a lender as part of a financing arrangement.

An equity warrant gives a lender the right to purchase a percentage of the company (typically between 1-5%) or a specified quantity of stock at a set price per share (e.g., exercise price). Thus, they are similar to a call option in the stock market.

Why do lenders use equity warrants?

Lenders sometimes use equity warrants as an alternative way to yield higher returns on the money they lend to companies and to compensate for the risk. This allows the lender to offer lower interest rates as the potential upside of a warrant offsets their risk of lending. However, in the world of venture finance, warrants can also have a significant downside for the lender and the borrower.  Everything in finance is about the trade-off between risk and reward. Therefore, many lenders and borrowers will negotiate a balance between higher/ lower interest rates with equity warrants.

How is a warrant exercised?

Warrants can last forever or for shorter periods.   The duration of the warrant period is generally a negotiated matter but can be up to 10 years and can have exercise prices set at a nominal amount or, again, a negotiated value.

When a company has a liquidity event, such as an IPO or private sale, the venture lender will be allowed (or required) to exercise their warrant as long as the price per share is above any set minimum “strike price.”

If the price per share is not above the strike price, they must wait for another liquidity event before exercising their warrant.

How lenders make money on the warrant.

After purchasing the shares at the warrant’s exercise price, lenders have the ability (often obligation) to sell those shares immediately at the sale price. Thus, the difference between prices is profit for the lender.

If the founders and other shareholders still owned the rights granted by the warrant, they would have realized this additional profit. This is why the actual cost of capital is impossible to predict when a warrant is involved.

When a company doesn’t perform as hoped, lenders often have additional protections for their investment. This protection is usually in the shape of a “put option.”

The Put Option

Also known as a “warrant put,” the put option gives the lender the right to sell the warrant back to the borrower for a specified amount of cash known as the “put amount.”

These options can usually be exercised a few years after the loan is issued or after the end of the term.

Think of the put amount as a guaranteed minimum for the lender. If a lender doesn’t want to hold the warrant any longer, they can put the warrant. Therefore, a borrower must expect to have to pay this amount.

If you give a warrant of 1% of your company and there is a put amount of $30,000, expect to pay at least $30,000.

A lender may want to exercise a warrant put at a time the company really needs cash, which can impact your company’s growth or financial strength.

Often, it is in the company’s best interest to refinance the put amount with another loan, further increasing their cost of capital.


Ultimately, warrants lead to widely varying costs of capital for borrowers. It is a diversification technique that allows lenders to get greater returns from the companies that do the best, but often at the expense of those companies.

If your company accepts an equity warrant and grows very well, the warrant may increase your cost of capital beyond financing options without warrants.  However, you may also have benefitted from a lower interest rate, so there is a clear trade-off.
