3 terms

one-for-one basis technical

"convertible into Class A ordinary shares at any time on a one-for-one basis"

conversion price financial

"without payment of any conversion price"

The conversion price is the fixed price at which a convertible security, like a bond or preferred stock, can be exchanged for shares of common stock. It acts like a set rate that determines how many shares an investor can receive if they choose to convert their investment. This helps investors understand the value and potential benefits of converting their securities into company shares.

expiration date technical

"The Class B ordinary shares have no expiration date"

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
