How Should Founders Address a Convertible Note That Includes Both a Conversion Feature and Warrant Coverage?

A convertible note with warrant coverage is not one instrument but two, and treating it as a single security can misstate your financials, taxes, and fully diluted ownership before an institutional raise. At issuance, the warrant requires separate documentation, valuation, and classification under applicable accounting standards, while its fair value may reduce the note's carrying value and create original issue discount. Maintain separate note and warrant registers, track OID, include the warrant in dilution modeling, and document whether it survives, converts, reprices, or expires at the next financing.

Key takeaways:

• The note and the warrant are separate instruments with separate records
• Bifurcation at issuance affects the note's carrying value and creates OID
• The warrant must appear in the fully diluted share count before a priced round
• Missing warrant documentation is a common and preventable diligence failure

Why a Note Plus Warrant Creates Two Separate Instruments

Most founders sign a note purchase agreement that bundles the debt terms and the warrant in the same document. That bundling is a legal convenience. Accounting treats each component separately.

The note and the warrant have different economic rights. The note is debt. It has a maturity date, an interest rate, and a conversion feature. The warrant is an equity purchase right. It gives the holder the right to buy shares at a fixed price on or before an expiration date.

Under ASC 470-20 and ASC 815, these two rights are accounted for separately at issuance. The warrant is bifurcated from the note. Its fair value is determined at the time of issuance and recorded separately. What remains after that allocation is the carrying value of the note.

The classification of the warrant also matters. If the warrant meets the criteria for equity classification under ASC 815, it is recorded in additional paid-in capital and stays there. If it does not meet those criteria, it is classified as a liability and must be remeasured at fair value each reporting period. Warrant terms that include cash settlement features, variable exercise prices, or certain anti-dilution adjustments can push a warrant into liability treatment. Founders should confirm classification with their accountant at issuance, not at the next audit.

For founders preparing for a priced round, the cap table issues that surface in Series B diligence often trace back to instruments that were never properly separated in the first place.

How Bifurcation Affects Carrying Value and OID

When the warrant is bifurcated from the note at issuance, its fair value becomes a debt discount. That discount reduces the note's initial carrying value below the face amount of the loan. The difference between the face amount and the reduced carrying value is OID.

Here is how the sequence works:

1. Determine the warrant's fair value at issuance. This is typically done using a Black-Scholes model or another acceptable valuation method. The inputs include the exercise price, the current share price or most recent 409A value, the expected term, volatility, and the risk-free rate. The method used and the inputs must be documented.
2. Allocate that fair value as a debt discount. The warrant's fair value reduces the carrying value of the note. If a $500,000 note is issued with a warrant valued at $40,000, the note is initially carried at $460,000.
3. Amortize the discount over the note's term. The $40,000 discount is amortized using the effective interest method over the life of the note. That amortization is treated as additional interest expense. It also creates OID for tax purposes.

OID must be tracked separately under IRC Sections 1272 and 1273. The investor must include OID in gross income as it accrues, even if no cash is received. The issuer must provide the investor with the information needed to track that accrual.

The practical risk: Many early-stage teams record the note at face value and never book the warrant separately. When an auditor or diligence team reviews the financials, the carrying value is wrong, the OID schedule does not exist, and the interest expense is understated. All three problems require restatement.

What Records Founders Must Maintain for the Warrant

The warrant is a separate legal instrument. It requires its own documentation trail, separate from the note file.

The Warrant Register

Every warrant issued must be logged in a warrant register. The register is a living record that tracks each outstanding warrant. At minimum, it must include:

• Holder name and contact information
• Issue date
• Exercise price per share
• Number of shares covered
• Class of shares (common, preferred, or a new series)
• Expiration date
• Vesting schedule, if applicable
• Exercise method permitted (cash, cashless, or both)
• Status (outstanding, exercised, expired, or cancelled)

The register must be updated each time a warrant is exercised, transferred, amended, or expires. A warrant that expired two years ago but still appears as outstanding on the cap table is a diligence problem. When the original warrant holder transfers the underlying note before conversion, documenting a convertible note transfer to a new holder requires the warrant register to reflect the change in holder information at the same time.

Valuation Support at Issuance

The fair value used to bifurcate the warrant must be supported by documentation. This means retaining the valuation model used at issuance, the inputs applied (exercise price, share price or 409A value, expected term, volatility, and risk-free rate), the name of the person or firm that performed the analysis, and the date of the calculation.

Black-Scholes is the most commonly used method for plain-vanilla warrants. If a different method was used, document why it was selected. The valuation memo does not need to be elaborate. It needs to be dated, defensible, and retained.

Exercise Records

When a warrant is exercised, two paths exist:

• Cash exercise: The holder pays the exercise price in cash. The company issues shares and records the cash received. Board consent or a written acknowledgment of the exercise is required.
• Cashless exercise: The holder surrenders a portion of the warrant to cover the exercise price. No cash changes hands. The company issues a net share amount. The calculation method and the resulting share count must be documented.

Both paths require a signed exercise notice, a board or officer acknowledgment, and an updated cap table. Accrued interest records on the underlying note must also stay current through the exercise date.

How Warrant Coverage Affects Conversion Math at a Priced Round

When a priced round closes, the note converts into equity. The warrant is a separate question. Its fate at the round depends entirely on what the original warrant agreement says and what the new investors require. For founders who anticipate an IPO path before a next private financing, convertible note treatment at an IPO requires its own review before the warrant outcome can be modeled.

Three outcomes are common:

1. The warrant survives the round. The holder retains the right to exercise at the original price for the remaining term. The warrant continues to appear in the fully diluted share count as a potential future issuance.
2. The warrant is cancelled or exchanged. The new investors or the company negotiates a cancellation, sometimes with a cash payment or a replacement instrument. The warrant register must be updated to reflect the cancellation and any consideration paid.
3. The warrant is repriced or modified. Anti-dilution adjustments in the original warrant agreement may trigger an automatic repricing when new shares are issued at a lower price. If that clause exists, the new exercise price and share count must be recalculated and documented at closing.

Why this matters for dilution math: Warrants count toward fully diluted shares even before they are exercised. If a warrant covers 100,000 shares and has not been exercised, those shares are included in the fully diluted count used to calculate ownership percentages, option pool sizing, and new investor economics. A warrant that is missing from the cap table understates dilution. A warrant that expired but was never removed overstates it.

Before any priced round, founders should confirm the current status of every outstanding warrant, model the fully diluted share count with warrants included, and confirm with counsel whether any warrant terms trigger automatic adjustment at the new round price. Warrants that survive the round remain in the fully diluted count until exercised or expired.

What Diligence Teams Find When the Warrant File Is Missing

Institutional diligence teams review financing instruments as a package. They pull the note, the warrant agreement, the cap table, and the financial statements together. When the warrant was treated as an afterthought, the gaps are visible across all four.

Common findings in warrant-related diligence failures:

• No warrant register, or a register that has never been updated since issuance
• The warrant is missing from the fully diluted cap table entirely
• The note's carrying value on the balance sheet equals its face amount, with no debt discount recorded
• No valuation memo or Black-Scholes calculation retained from issuance
• OID schedule absent from the financial records
• Expired warrants still listed as outstanding in cap table software
• No documentation of whether cashless exercise is permitted, and no exercise notice on file for warrants that were exercised
• State securities filings for the warrant issuance not completed or not retained

That last point deserves attention. In some states, the issuance of a warrant to an investor triggers a separate notice or filing obligation under state securities law, independent of the Regulation D filing for the note itself. Whether that obligation exists depends on the state of the investor's residence and the state of the company's formation. Counsel should confirm at issuance whether a separate filing is required. Founders issuing notes to international investors face additional layers of this analysis, which convertible note issuance to international investors covers in detail.

What Happens When the Warrant Is Found Late

A growth-stage software company raised seed capital through a convertible note that included warrant coverage. The note was tracked carefully. The warrant was not. No warrant register was maintained. The warrant did not appear in the cap table. The fair value was never bifurcated from the note at issuance, so the carrying value on the balance sheet was overstated and no OID schedule existed.

When the company entered a Series A process, the lead investor's counsel pulled the note purchase agreement during initial document review. The warrant agreement was attached. Counsel asked for the warrant register, the valuation support, and the OID schedule. None existed.

The company spent six weeks working with outside counsel and its accountant to reconstruct the bifurcation calculation, restate the carrying value, build the OID schedule retroactively, and update the cap table. The Series A timeline slipped. The lead investor required a representation and warranty that no other unregistered instruments existed before closing.

Both outcomes were preventable. The delay and the credibility cost came from treating the warrant as a footnote to the note. It had its own obligations from day one.

Preparing the Warrant File Before Institutional Outreach

Investors read a note-plus-warrant package as a single financing event with two instruments. They expect both to be documented, reconciled, and reflected accurately in the financials and cap table.

Before any institutional outreach, teams should reconcile the note terms, warrant records, OID schedule, and cap table treatment as a connected set. A warrant that is missing from one of those four places is a gap that counsel or an auditor will find.

IRC Partners works with founders and finance teams to identify structural documentation gaps before they surface in diligence. If your seed round included warrant coverage and the records have not been reviewed since issuance, that review should happen before outreach starts.

Frequently Asked Questions

Does a warrant always survive a priced round?

No. The warrant's fate at a priced round depends on the original warrant agreement and what the new investors require. Some warrants survive unchanged. Others are cancelled, exchanged for a cash payment, or repriced under anti-dilution provisions. Founders should review the warrant agreement with counsel before any priced round closes and confirm the outcome in writing at closing.

Does a cashless exercise change the records required?

Yes. A cashless exercise produces no cash payment but requires documentation of a different kind. The company must record the surrender calculation, the net share amount issued, a signed exercise notice from the holder, and board or officer acknowledgment. The cap table must be updated to reflect the net shares issued and the warrant's cancellation.

Do expired warrants still create diligence questions?

They can. An expired warrant that was never removed from the cap table creates a discrepancy between the register and the fully diluted share count. Diligence teams will ask why it is still listed. If the warrant expired without notice to the holder, there may also be a question about whether proper expiration procedures were followed. Clean the register when a warrant expires.

Does warrant coverage change the fully diluted share count before exercise?

Yes. Warrants are included in fully diluted shares outstanding even before exercise. A warrant covering 150,000 shares adds 150,000 shares to the fully diluted count used for ownership modeling, option pool calculations, and new investor economics. A warrant missing from the cap table understates dilution. That discrepancy will surface when a lead investor runs their own model.

Do founders need a separate valuation memo for the warrant at issuance?

Yes. The fair value allocated to the warrant at issuance must be supported by a documented calculation. Black-Scholes is the most common method. The memo does not need to be long, but it must include the valuation date, the inputs used, the method applied, and who performed the analysis. Without it, the bifurcation entry on the balance sheet has no support.

Can warrant issuance trigger state securities filing obligations separate from the note?

It can. Some states require a separate notice or filing when a warrant is issued to an investor, independent of the Regulation D exemption used for the underlying note. The obligation depends on the investor's state of residence and the company's state of formation. Founders should confirm with securities counsel at issuance whether a state-level filing is required for the warrant.

Will a lead investor ask for warrant exercise and expiration records before closing?

Yes. Institutional investors and their counsel will request the warrant register, the original warrant agreement, and documentation of any exercises or expirations as part of standard financing diligence. If a warrant was exercised using cashless mechanics, the net share calculation and exercise notice will be requested. If a warrant expired, confirmation that the register was updated will be expected.
