Our % dedicated bitcoin mining operations is currently located at Coinmint LLP’s Massena, New York facility which houses our currently deployed hardware fleet consisting of 6, next generation Bitmain Antminers. We currently have a deployed hash rate capacity of PH/s utilizing approximately megawatts (MW) of energy.

Riot has 1, more S19 Pros scheduled for delivery in early November which is expected to increase our hash rate capacity to PH/s utilizing approximately MW of energy.

We also have 8, S19 Pros scheduled for delivery in equal installments over the first four months of By early May we are expected to have a total hash rate capacity of EH/s (1, PH/s) while utilizing approximately 46 MW of energy.

Summary of Riot's bitcoin mining growth milestones:

February – 4, S17 Pro miners deployed bringing operational hash rate capacity to PH/s.

April – Riot enters co-location hosting agreement with Coinmint in Massena, NY to reduce the Company's cost of production and increase available MW capacity for expansion. 1, S19 Pro miners ( TH/s) are ordered from Bitmain.

May – 1, S19 miners (95 TH/s) are ordered from Bitmain, bringing the total outstanding order to 2, miners. De-commissioned and sold original fleet of prior generation low efficiency miners, upon halving event.

July – First order of 1, S19 Pro ( TH/s) miners are received and deployed in Massena, NY. Riot's mining fleet totals 5, miners with an operational hashing capacity of PH/s.

August – Second outstanding order consisting of 1, S19 (95 TH/s) miners are received and deployed in Massena, NY. Riot's mining fleet totals 6, miners with an operational hashing capacity of PH/s. 8, S19 Pro miners ( TH/s) are ordered from Bitmain.

November - The third outstanding order consisting of 1, S19 Pro ( TH/s) miners is expected to arrive, which will bring Riot's mining fleet to a total of 7, miners, with an expected operational hashing capacity of PH/s.

January – April - The newly announced order of 8, S19 Pro (TH/s) miners are expected to be received and deployed during the first four months of and are expected to raise Riot's total operational hash rate capacity to EH/s (1, PH/s). Riot expects to then have a fully deployed fleet totaling approximately 15, miners.
