Remember this first
First, 3 things to remember
- 1A unit is a bundle of multiple securities, and its composition varies by contract.
- 2In addition to the warrant price, an exercise cost may be required to receive the shares.
- 3A total loss is possible due to expiration, mandatory redemption, or exercise restrictions.
What is included in the package?
A SPAC unit can be a bundle of common stock and warrants or other rights. For example, if 1 unit includes 1 share of common stock and 1/3 of a warrant, you must collect the warrant portions of 3 units to obtain 1 full warrant. This is a hypothetical configuration; you must check the prospectus for the actual ratio.
Check when unit separation trading is possible, as well as the brokerage's separation application process and fees. Suffixes like U, .U, W, or WS are just clues, not standardized guarantees. First, verify whether the order is for common stock or units.
A warrant does not mean you are currently a shareholder.
A warrant is a right to purchase a certain number of shares at a set price and within a set period according to the contract. Typically, it does not carry voting rights or dividends of common stock before exercise. If new shares are issued upon exercise, existing equity may be diluted.
11.50 dollars is a common exercise price in some SPAC structures, but it is not the rule for all warrants. Check the number of warrants required to receive one share of stock, the start date for exercise, the expiration date, and the registration conditions individually.
The warrant purchase price and the exercise price are separate.
Hypothetically, if a contract allows you to buy 1 warrant for 2 dollars and pay an additional 11.50 dollars to receive 1 share, the simple total acquisition cost is 13.50 dollars. This example excludes fees and taxes. Just because the underlying stock is 12 dollars does not mean a warrant investor automatically makes a profit.
If the stock price is below the exercise price at expiration, the warrant may expire worthless, resulting in the loss of the entire purchase amount. The price before expiration is also influenced by remaining time and volatility. Do not assume it moves by the same percentage as the common stock.
Call and cashless exercise conditions.
The company may notify you to redeem warrants for a very low amount under certain conditions. If you miss the notice or pass the brokerage's exercise deadline, you may lose a valuable right. Even if listed, your brokerage may not support the exercise.
Cashless exercise does not mean receiving a share of stock for free without cash. The number of shares received may be reduced according to the contract's formula. Read the terms regarding registration, merger completion, stock price conditions, and mandatory exercise.
They are also different from options, rights, and convertible bonds.
Rights may be structured to receive a portion of shares upon meeting conditions such as a merger, while convertible bonds combine bond and stock conversion conditions. Exchange-traded options and company-issued warrants may also differ in issuer, contract, and dilution effects.
In all cases, you must read the contract, not just the name. Even if the underlying stock price surges, returns may differ if the rights conditions or exercise possibilities vary, and if a SPAC is liquidated, warrants may not have the same trust redemption rights as common stock.
You should not make such assumptions
“Buying a warrant means you already own the shares at the exercise price.”
You have purchased a right. You must meet additional funding, time, and condition requirements to receive shares, and the right may expire.
Check what you have read.
- Have you checked the unit composition and separation conditions?
- Have you checked the number of shares per warrant and the exercise price?
- Have you read the expiration, call, and exercise restrictions?
- Have you confirmed the brokerage's exercise support and deadlines?
