Warrants

In depth

A warrant is a contract between a company and an outside party that says: at any point in the next N years, the holder may pay the strike price and receive a share of stock. Strike prices are usually set at issuance, typically pinned to the most recent priced round's per-share price or to a discount thereof. Terms run five to ten years, longer than most employee options.

Warrants are valued like long-dated call options. A Black-Scholes-style model produces the fair value at issuance, and the negotiation focuses on three levers: how many shares underlie the warrant, what the strike price is, and whether exercise is cash or cashless. Venture debt lenders push for low strikes and large share counts. Founders push back on both.

The most common context for warrants in venture finance is the equity kicker attached to debt. Venture debt lenders take 3-20% warrant coverage on principal. Mezzanine lenders sometimes take penny warrants where the strike is nominal, which is closer to issuing equity than to selling an option. PIPE deals on public companies almost always include warrants for the institutional investors.

Why it matters

Warrant dilution is the dilution that founders most often miss. A $5M venture debt facility looks non-dilutive on the term sheet, but the attached warrants commonly transfer 0.5-2% of the company to the lender at a strike that the lender expects to be deep in the money by exit. Across multiple debt facilities and PIPE rounds, warrant dilution can add up to several percent of the company.

The other direction matters too. For investors and lenders, warrants are the source of most of the upside in deals that would otherwise be capped at debt-like returns. Hercules Capital reports realized multiples on monetized warrants from 1.02x to 42.71x since inception, meaning the warrant book carries the equity-like part of the return.

Worked example

A growth-stage company takes a $10M venture debt facility with 6% warrant coverage. The most recent equity round priced shares at $5.00.

Warrant coverage value = $10M * 6%           = $600,000
Strike price           = $5.00 per share (last round price)
Shares underlying      = $600,000 / $5.00    = 120,000 shares

Four years later the company IPOs at $25 per share. The lender exercises the warrants:

Intrinsic value at IPO = ($25 - $5) * 120,000 = $2,400,000
Multiple on warrant    = $2.4M / $600K        = 4.0x

Combined with cash interest already earned, the lender's blended IRR comfortably clears the 12-15% range targeted on the debt side. The company gave up roughly 0.3% of fully diluted equity at exit, in exchange for $10M of non-dilutive runway when it was raised.
