Floor Prices, Warrants, and Conversion Mechanics

Reading conversion terms that worsen dilution.

The mechanical terms inside a structured convertible determine whether it produces a death spiral or a benign capital event. Three specific feature families do most of the work: the floor price (or lack thereof), the warrant structure attached to the convertible, and the conversion mechanics themselves. Reading the deal documentation correctly is what separates structural analysis from headline-level reaction.

Floor prices

A floor price is the minimum conversion price the structured convertible can reach regardless of market action. In principle, a meaningful floor caps the death-spiral mechanic. In practice, floors vary widely in effectiveness:

Floors near current price: Effective. The mechanic cannot accelerate dilution past a defined point.
Floors at $0.10 on a $5 stock: Functionally absent. Allows essentially unlimited dilution before constraint binds.
Reset floors with adjustment terms: Hybrid; the floor itself can be reset on subsequent events.
Floors with associated penalty payments: If conversion would occur below floor, the issuer pays cash penalty. Generally beneficial for equity holders.

The diagnostic question: at the current stock price, how far down would the stock need to fall before the floor binds? If the answer is > 80%, the floor is functionally absent.

Warrant structure

Most structured convertibles include warrants. The warrant terms can be more dilutive than the convertible itself:

Strike price. Warrants struck below current price are immediately in-the-money. Cashless exercise produces dilution without compensating cash inflow.

Exercisability. Warrants exercisable immediately at issuance produce near-term dilution. Warrants with delayed exercisability postpone the effect but the cumulative dilution potential is the same.

Adjustment provisions. Warrants with most-favored-nation or anti-dilution-adjustment provisions can reset to lower strikes on subsequent events. The reset extends the structural pressure.

Cashless-exercise formulas. Standard cashless-exercise produces (current price - strike) / current price worth of shares per warrant. Modified formulas can be more or less dilutive.

Black-Scholes-based exercise on redemption. Some SPAC-warrant-style provisions allow holders to receive an alternative share count based on a Black-Scholes valuation table. Can produce significant dilution in volatility scenarios.

Conversion mechanics

The conversion mechanic determines how many shares the holder receives per dollar of convertible notional:

Notional / conversion price = share count delivered.

For fixed-conversion-price instruments, the share count is known. For variable-conversion-price instruments, the share count is a function of the stock price at conversion.

Common variable structures:

"Conversion price = X% of lowest VWAP over N preceding days."
"Conversion price = average VWAP over N preceding days, subject to floor and ceiling."
"Conversion price = lower of (a) fixed price and (b) X% of recent VWAP."

Each structure produces different dilution patterns. The lower the bound on conversion price, the more potential dilution.

Anti-dilution adjustments

Standard anti-dilution adjustments protect convertible holders against splits, dividends, and other corporate actions that would otherwise dilute their effective claim. These are usually benign — they preserve the original economic terms.

More aggressive adjustments:

Most-favored-nation (MFN): Resets conversion price if the issuer subsequently issues securities at lower prices. Often used in structured PIPEs.
Weighted-average ratchet: Partially resets based on subsequent issuances; less aggressive than full MFN.
Full ratchet: Complete reset to the new lower price regardless of size of subsequent issuance.

Full ratchet is the most aggressive and typically appears only in distressed-issuer structures.

Reading the form-of-note exhibit

The actual instrument terms are in the form-of-note (or form-of-preferred-stock-designation) filed as an exhibit. Sections to read carefully:

Conversion section. Defines the conversion price formula, frequency, and limits.
Anti-dilution adjustments section. Lists the triggering events and the adjustment formulas.
Reset and true-up provisions. Often in separate sections; describes post-conversion adjustments.
Default and acceleration provisions. Describes consequences of issuer events of default; some accelerate conversion at the most-dilutive available terms.

Quantifying potential dilution

For a candidate structured convertible, the maximum potential dilution scenario:

Assume stock reaches the lowest credible value (below the floor if floor is weak).
Compute conversion price at that level using the convertible formula.
Compute share count at that conversion price (notional / conversion price).
Add associated warrant share count assuming full cashless exercise at the same low price.
Compare total potential share issuance to pre-convertible shares outstanding.

Outcomes of 5-10x dilution in maximum-stress scenarios are not unusual for aggressive structured deals.

The honest reading

Most convertibles in the US market are benign. The structured ones are concentrated in a specific subsegment of small- and micro-cap issuers, with a small number of recurring counterparties. Recognizing the pattern is operational — once you've read 10 toxic financings the structural patterns repeat.
