MicroStrategy (MSTR) said late Tuesday it is planning to offer $2 billion worth of 0% convertible senior notes due 2030 in a private offering.

The company said it expects to grant initial purchasers the option to purchase up to $300 million worth of additional notes within five business days from the date of issue.

The initial conversion rate will be determined at the pricing of the offering, the company said.

MicroStrategy said it plans to use the net proceeds from the offering for general corporate purposes.
