Riot Blockchain Continues to Increase Production Efficiencies and Aggressive Expansion of Bitcoin Hash Rate, Reaching 567 PH/s with Latest Purchase

CASTLE ROCK, Colo., June 3, 2020 /PRNewswire/ -- Riot Blockchain, Inc. (NASDAQ: RIOT) ("Riot" or the "Company"), one of the few Nasdaq-listed cryptocurrency mining companies in the United States, has purchased an additional 1,000 next-generation Bitmain S19 Pro (110 TH) Antminers for USD $2.3 million from BitmainTech PTE. LTD. ("Bitmain"). This purchase was funded using available working capital and Riot has no long-term debt.

By Q4 2020, without any further miner purchases, Riot estimates its aggregate operating hash rate to be approximately 567 petahash per second ("PH/s") consuming 14.2 megawatts of power, assuming full deployment of the total 7,040 next-generation miners. This would represent an estimated 467% over Riot's average mining hash rate as of late 2019 and an efficiency rating of 38.6 joules per terahash ("J/TH") versus 98 J/TH in 2019. These new generation miners are expected to operate at nearly 467% of the late 2019 hash rate, utilizing only approximately a 50% increase in energy consumption.

Riot anticipates that the additional S19 Pro (110 TH) & S19 (95 TH) 3,040 miners will be deployed as received in the second half of 2020 and are estimated to represent over 56% of Riot's total hashing capacity. These miners will be deployed at Coinmint's Massena facility pursuant to the previously disclosed hosting arrangement that Riot entered as part of its continuing efforts to significantly decrease costs of production.

The May 2020 halving, the third in the network's history, means the mining reward has now been reduced from 12.5 bitcoins per block to 6.25 block rewards. Bitcoin miners continue to face pressure from the halving event which occurred in May 2020, as the event directly affected mining revenues. Mine operators that failed to upgrade to more efficient mining rigs and / or secure cheaper power may succumb to the negative effects of the halving event. In 2020, Riot reinforced its confidence in bitcoin by focusing on bitcoin mining and further investing in a full upgrade & expansion of its mining fleet with the objective of increasing operational efficiency and performance in the post-halving mining environment.

By advancing on these goals with the most energy efficient miners available, Riot has established a more strategically advantageous position relative to less efficient competition. Coupled with the unique ability to efficiently access the capital markets as a Nasdaq-listed company, Riot is positioned to operate more effectively post-halving and create value for its shareholders.
