All of the miners to be acquired under the purchase agreements with Bitmain and SuperAcme are scheduled to be delivered through December 2022.

The Company also has an agreement for the purchase of between 28,000 to 56,000 mining rigs from Bitfury Top HoldCo, made under, and as a part of, the Master Services and Supply Agreement between the Company and Bitfury Top HoldCo dated August 26, 2021.

The delivery of those containers commenced in the first quarter of 2022 and is anticipated to be completed in 2022, as expected.
