Mountain Crest Acquisition Corp. V (MCAGR)

Mountain Crest Acquisition Corp. V rights, trading under the ticker MCAGR, are a derivative security bundled with the SPAC’s initial public offering. When the blank-check company raised capital from public shareholders, it issued shares and rights as a package deal. The rights are contractual claims that allow the holder to purchase additional shares of Mountain Crest at a pre-determined price once a business combination has been announced and shareholder approval is obtained.

The structure of SPAC rights and their place in the capital raise

When Mountain Crest conducted its initial public offering, it structured the offering around three components: common shares, warrants, and in this case, rights. The rights represent a claim to purchase additional shares at an exercise price established in the prospectus. Unlike warrants, which can typically be exercised for a period of years after a business combination closes, rights are generally more time-limited and are exercisable only under specific conditions—usually triggered by the announcement of a target company or the completion of a business combination.

The rationale for bundling rights with the initial offering is to sweeten the deal for public investors. While SPAC shares can be redeemed if shareholders dislike a proposed merger, rights give non-redeeming shareholders the opportunity to increase their ownership stake in the combined company at a locked-in price. This is particularly valuable if the merged entity’s shares trade above the rights’ strike price on the day they become exercisable. From the SPAC sponsor’s perspective, the rights also create an incentive for shareholders to remain invested rather than redeem, because redemption typically disqualifies the right from being exercised.

Exercisability and the triggering event

Rights in a SPAC become exercisable upon a defined triggering event spelled out in the prospectus and the rights agreement. For Mountain Crest, this might be the closing of a business combination or the announcement of a definitive agreement with a target company. The prospectus will specify the exact conditions: whether shareholders must approve a merger, whether the right can be exercised before or only after that approval, and what period of time is available for holders to exercise their rights.

The exercise mechanics are straightforward. A rights holder presents the right and pays the exercise price to acquire one additional share of the merged company. If the market price of that share is higher than the strike price, the right has economic value and will be exercised by rational investors. If the merged company’s share price trades below the strike, most rights will expire worthless because there is no economic incentive to exercise.

Risks and the path to expiration

Rights carry several types of risk. First, if no business combination is completed within the SPAC’s deadline—typically two to three years—the SPAC is liquidated, and the rights expire worthless. The trust account is returned to shareholders, but holders of rights receive nothing. This is liquidation risk, and it directly corresponds to whether Mountain Crest’s sponsor can identify and close a viable business combination within the timeframe.

Second, there is dilution risk. If a business combination closes and the merged company’s share price falls below the exercise price of the rights, the rights will not be exercised, but they will still exist as contingent liabilities on the cap table. The shareholder base is not diluted, but the fact that rights are outstanding and could theoretically be exercised in the future represents a potential claim on the company’s value.

Third, rights can be redeemed or expired by the issuer if specific conditions in the prospectus are met. If the merged company’s share price trades significantly above the strike price, the company may choose to call or redeem the rights, forcing holders to exercise or lose them. This is less common with rights than with warrants, but the prospectus will detail any such provisions.

Comparing MCAGR to common shares and warrants

MCAGR is distinct from MCAG (common shares) because it gives holders a future purchase right rather than current ownership. Holders of MCAGR have no voting rights until their rights are exercised and they acquire underlying shares. MCAGR is also different from warrants because warrants typically have a longer exercise period extending years after a business combination and carry different fee and expiration structures. MCAGR’s value is therefore more tightly tethered to whether and when the SPAC merges, whereas warrants retain value for years afterward regardless.

Monitoring MCAGR as an investor

An investor holding MCAGR should track Mountain Crest’s progress toward a business combination through SEC filings and investor updates. Once a target is announced or a merger is proposed, the prospectus supplement and proxy statement will specify the exact exercise terms, expiration dates, and any redemption provisions. Rational exercise requires comparing the strike price to the merged company’s anticipated or actual trading price at the moment the right becomes exercisable.
