Warrant Overhang: How to Count Shares Not Issued Yet

What does warrant overhang mean?

A warrant is a contract that gives its holder the right to buy a company's shares at a fixed price, the exercise price (also called the strike), until an expiry date. Warrants are handed out constantly in small-cap financings as a sweetener: buy a share, get a warrant to buy another one later.

Every outstanding warrant is a share that could appear in the future. Added together, those potential shares are the company's warrant overhang. They are not in the shares outstanding figure on a quote page, but they are a real claim on the company's equity, and they tend to be exercised exactly when the stock has risen above the strike.

Where warrants come from

Warrants usually arrive attached to a financing:

• Registered direct offerings and PIPEs. Investors receive, for example, one warrant per share purchased, often exercisable at or slightly above the offering price for five years.
• Underwritten offerings. Units of one share plus one warrant are common in small-cap public offerings.
• Placement agent compensation. The broker that arranged a deal often receives its own warrants, typically covering a small percentage of the shares sold.
• Debt deals. Lenders frequently receive warrants alongside a loan or convertible note.

Each issuance is announced in an 8-K or a prospectus supplement, and each one adds a line to the warrant table in the company's financial statement notes.

Reading the warrant table

The notes to the financial statements in a 10-Q or 10-K usually contain a table listing warrants outstanding by series, with the number of shares, exercise price and expiry date. Here is a hypothetical example for Company X, which has 40,000,000 shares outstanding and a stock price of $1.50.

All figures are hypothetical.

Total overhang is 28,000,000 shares, equal to 70% of the current share count. If every warrant were exercised, Company X would have 68,000,000 shares. But only 14,000,000 of them are in the money at today's price, so the overhang that matters now is smaller than the headline total.

Three ways a warrant becomes shares

How many new shares an exercise creates depends on how it is exercised.

Cash exercise

The holder pays the exercise price and receives one share per warrant. Company X's 10,000,000 PIPE warrants at $1.00 would add 10,000,000 shares and $10,000,000 of cash.

Cashless exercise

A cashless exercise lets the holder surrender part of the warrant's value instead of paying cash, receiving only the net shares. It is often available only when no effective registration statement covers the warrant shares. The standard formula is:

Net shares = Warrant shares × (Market price − Exercise price) ÷ Market price

For the same PIPE warrants at a $1.50 market price: 10,000,000 × ($1.50 − $1.00) ÷ $1.50 = 3,333,333 shares, and the company receives no cash. Fewer shares are issued, but nothing is paid in.

Pre-funded warrants

A pre-funded warrant is a warrant whose price was almost entirely paid upfront, leaving a nominal exercise price such as $0.0001. They are used so an investor can buy into a deal without immediately owning shares above an ownership blocker threshold. Economically, they are shares waiting to be issued. Company X's 3,000,000 pre-funded warrants should be counted as near-certain future shares, not as optional ones.

Why the exercise price matters

An out-of-the-money warrant (strike above the market price) is rarely exercised, because the holder could buy shares cheaper in the market. An in-the-money warrant can be exercised and the shares sold at a profit, as long as the shares are registered for resale, often through an S-1 resale registration, or otherwise tradable.

This is why traders pay attention to strike prices: they mark levels at which a new source of share supply becomes economic. If Company X traded at $2.00, the 2024 series at $1.75 would also be in the money, adding 8,000,000 more potential shares to the in-the-money pool. Whether holders actually exercise and sell depends on many things, including their own positions and the registration status of the shares, so a strike price is a point where supply can appear, not a forecast that it will.

Terms that change the count over time

Some warrant agreements contain clauses that make the overhang move:

• Price resets. The exercise price drops if the company later sells shares at a lower price. Some resets also increase the number of warrant shares so the total exercise proceeds stay the same.
• Inducements. A company may offer holders a lower exercise price, or new warrants, in exchange for exercising now. This warrant inducement raises cash quickly but often replaces old overhang with new.
• Alternative cashless exercise. Some agreements let holders exercise for a fixed number of shares per warrant with no cash and no market-price formula, which can create more shares than the standard cashless formula.

These clauses are in the warrant agreement, which is usually filed as an exhibit to the 8-K announcing the financing.

How to check a company on Signal8

• Each company page has a Dilution tab, for example AAPL's Dilution tab, where Signal8 organises warrants and other instruments it has extracted from filings. Coverage focuses on small-cap issuers.
• The dilution screener lets you compare companies on dilution-related data.
• Warrant tables are where dilution tools differ most, in coverage and in how a figure is sourced. Our comparison of dilution trackers covers six of them, and Signal8 vs DilutionTracker compares two side by side.
• In the Terminal, open AAPL or any symbol to see price and filings side by side.
• To total a company's warrants, convertibles and remaining ATM capacity against its share count, use the warrant and dilution overhang calculator. Its defaults reproduce the Company X table above.
