Production and operational updates

In May 2021, Riot produced 227 BTC, an increase of about 220% from its production of 71 BTC in May 2020. Halving BTC production in the same period of 2020 from 460 BTC. As of May 31, 2021, Riot held approximately 2,000 BTC, all of which were produced by its mining operations.

The company plans to continue providing monthly operational updates and unchecked production results through the end of 2021. These updates are designed to keep shareholders informed of Riot’s mining production as it continues to deploy its growing fleet of miners.

Whinstone acquisition completed

May 2021, Riot announced that it had completed its previously announced acquisition of Whinstone US (“Whinstone”). Whinstone’s Bitcoin mining facility in Rockdale, TX is the largest Bitcoin mining facility in North America by its 300 MW developed capacity. The company announced plans to immediately begin further development of additional capacity at Whinstone to rapidly bring the property to its current capacity of 750 MW. This expansion is being driven by Whinstone’s industry-leading development team of over 100 people.

Whinstone’s comprehensive energy management strategy delivers best-in-class net energy costs of approximately 2.5 cents per kWh using state-of-the-art technology and extensive analytics to deliver industry-leading low-cost, reliable and responsive energy.

Current miner deliveries

As part of an order from Bitmain in December 2020, 1,000 S19 Pro Antminers (110 TH) were delivered at the end of May 2021. Installation of the 1,000 miners is expected to be completed in Q2 2021, and once additional miners are fully deployed with the existing Riot fleet, Riot will have a total of 23,946 Antminers in operation, consuming approximately 76 megawatts (“MW”) of energy, with one estimated hash rate capacity of 2.4 exahash per second (“EH / s”).

These 1,000 S19 Pro Antminers will be deployed at the Whinstone plant along with the previously announced delivery of 6,500 Antminers. Riot continues to receive miner supplies from Bitmain as planned.

Hash rate growth

By Q4 2022, Riot expects a total hash rate capacity of 7.7 EH / s assuming full deployment of its projected fleet of approximately 81,146 Antminers acquired by Bitmain, 95% of which are the latest generation of miners will be the S19 series. When fully deployed, the company’s total fleet is expected to consume approximately 257.6 MW of energy, with approximately 208 MW used at Riot’s Whinstone facility and approximately 51 MW at Coinmint LLC’s facility. This results in an overall hash rate efficiency of 33 joules per terahash (J / TH).
