A stock warrant gives the holder the right to buy shares at a fixed price for a set period of time. Startups rarely issue warrants in ordinary seed or Series A rounds. They show up mainly as “warrant coverage” on venture debt and in strategic partner deals, and they need board approval to issue, amend or extend.
Key takeaways
A warrant is a contract that lets the holder buy a set number of shares, of a set class, at a set price (the exercise price), at any time before the warrant expires. If the company’s shares become worth more than the exercise price, the holder can exercise and capture the difference. If they don’t, the warrant expires unused.
Warrants of private companies can’t be traded on any market. They are restricted securities, and the warrant agreement almost always limits transfers without the company’s consent.
Economically, a warrant and a stock option work the same way: both are rights to buy shares at a fixed price. The difference is who gets them and why. Stock options go to employees, directors, advisors and other service providers as compensation, and they are granted under the company’s equity incentive plan. Warrants go to third parties, such as lenders and commercial partners, as part of a financing or business deal.
That distinction matters because the equity incentive plan generally only allows grants to people providing services. A lender or partner can’t receive options under the plan, so the company issues a standalone warrant instead. Board members and advisors should get options or restricted stock under the plan, not warrants. See Stock Options.
Venture debt. This is where most founders first meet warrants. A venture lender will ask for “warrant coverage,” a warrant worth a percentage of the loan amount, often in the range of 5% to 15%. The warrant is usually exercisable into the class of preferred stock sold in the company’s last priced round, at that round’s price, or into the next round’s stock if the company hasn’t raised a priced round yet.
Strategic and commercial deals. A large customer, channel partner or platform may ask for a warrant as part of a commercial agreement. These warrants often vest on milestones, such as revenue the partner brings in, so the partner only earns the equity if the deal delivers.
Bridge financing. Investors in a bridge loan or convertible note sometimes ask for a small warrant as a sweetener. See Convertible Notes.
Warrants issued alongside preferred stock in an ordinary venture round are uncommon today. If an investor asks for one, treat it as a valuation discount and negotiate it that way.
Say your company borrows $2,000,000 in venture debt with 10% warrant coverage, and your Series A price was $1.00 per share. The lender gets a warrant to buy $200,000 worth of Series A preferred at $1.00 per share, which is 200,000 shares.
The lender doesn’t pay anything for the warrant itself. If the company later sells for $5.00 per share, the lender can exercise and buy 200,000 shares for $200,000, shares that are then worth $1,000,000. If the company never exceeds $1.00 per share, the warrant is worthless.
Check what the coverage is measured against. Some lenders size the warrant on the full facility at signing, even if you never draw all of it. Others start with the first draw and add shares as you borrow more. Where you can, tie coverage to the amount you actually borrow, so you don’t give up equity for money you never take.
Every warrant agreement should state the number of shares and the class of stock, the exercise price, the expiration date, and how the holder exercises. Most warrants also include a “net exercise” (cashless exercise) right, which lets the holder exercise without paying cash by receiving fewer shares, with the exercise price paid out of the warrant’s built-in value.
The exercise price is usually the price per share of the last priced round or the stock’s current fair market value. Occasionally a warrant carries a nominal price, such as $0.01 a share. A “penny warrant” like that is close to an outright stock grant, so value it that way when you negotiate.
The terms worth negotiating are the term (lenders typically ask for seven to ten years), any adjustment to the share count if the company raises at a lower price, transfer restrictions, and what happens on an acquisition. A well-drafted warrant either terminates at an acquisition if not exercised, or is automatically net exercised, so the buyer doesn’t have to deal with an outstanding right to buy stock in a company that no longer exists.
To issue a warrant, the board approves it, usually by written consent, and the company signs a warrant agreement with the holder. The company must have enough authorized and unissued shares of the relevant class to cover the warrant if it’s exercised. Depending on the type of fundraise, you may need to file a Form D and state blue sky filings.
To extend a warrant, the board approves an amendment, and the company and the holder both sign it, before the warrant expires. If the warrant has already expired, there is nothing left to amend. The company would need to issue a new warrant, at a price set at the time of the new grant.
Taxes depend on why the warrant was issued. Warrants issued to lenders or commercial partners as part of a deal generally aren’t compensation. A warrant issued to someone in exchange for services is compensation and is treated much like a nonqualified stock option, so it should be priced at fair market value, and changing its terms can have tax consequences. Talk to a tax advisor before issuing or extending a warrant for services. See 409A Valuation.
Warrants are part of your fully diluted capitalization from the day they are issued: fully diluted shares are issued and outstanding shares, plus the full option pool, plus warrants. In the example above, the lender’s 200,000 shares count against every stockholder’s fully diluted percentage even before exercise. Investors in your next round will count them too. See Authorized, Outstanding and Fully Diluted Shares and What Is a Cap Table?
