Riot Blockchain Announces Milestone Purchase of 8,000 S19 Pro Antminers from Bitmain with Delivery Starting January 2021, Resulting in 1.45 EH/s in Total Hash Rate

Riot's Hash Rate Expected to More Than Double to 1.45 EH/s by April 2021 with 15,040 Miners Deployed; Exceeding Disclosed Goal of 1 EH/s by early 2021.

CASTLE ROCK, Colo., Aug. 17, 2020 /PRNewswire/ -- Riot Blockchain, Inc. (NASDAQ: RIOT) ("Riot", "Riot Blockchain" or the "Company"), announces the execution of a purchase agreement for 8,000 next generation Bitmain S19 Pro Antminers (110 TH) for USD $17.7 million from BitmainTech PTE. LTD. ("Bitmain") for receipt and deployment starting in January 2021. Due to the substantial size of the order, Riot secured a lower cost per miner as compared to previous purchases, despite the recent increase in the price of bitcoin ("BTC"), which historically has increased the purchase price of miners.

This purchase agreement has a defined delivery schedule of 2,000 S19 Pros per month starting in January 2021 and continuing through April 2021 until the order is complete.

This transaction positions the Company to achieve and exceed its previously reported goal of exceeding 1 exahash per second (EH/s) of total hash rate capacity by early 2021. When fully deployed, Riot expects its total hash rate capacity to be approximately 1.45 EH/s (1,446 PH/s) while utilizing approximately 47 megawatts (MW) of energy.

"This substantial order of 8,000 next-generation miners is a milestone for the Company, demonstrating that the second phase of Riot's strategic transformation is well underway," said Remo Mancini, Independent Chairman of Riot Blockchain. "We have previously announced our goal to become one of the largest bitcoin miners in North America and this purchase represents a significant step in achieving that goal. With our current miner deployment schedule, we anticipate that based upon current factors, Riot would achieve positive cash flow in late 2020."

The Bitmain Antminer S19 Pro is the latest generation BTC Application-Specific Integrated Circuit ("ASIC") miner offered by industry-leading hardware manufacturer Bitmain. The S19 Pro boasts a hash rate of 110 TH/s with an energy efficiency of 29.5±% 5 joules per terahash (J/TH). Riot is focused on building its mining operations with the highest performance mining hardware available, making the S19 Pro the clear choice for its expansion.

"The latest order from Riot Blockchain marks another milestone for their company as they continue to expand their mining operations across North America. The Antminer S19 Pro houses the latest technology offered by Bitmain, achieving remarkable hash rates that serve to further the growth and position of the company. We are confident with their business and continue to strengthen our relationship with Riot Blockchain", said Irene Gao, Antminer Sales Director of NCSA Region, Bitmain.

In combination with its 7,040 disclosed fleet of miners, this order of 8,000 S19 Pros is expected to bring the Company's aggregate mining efficiency to 33.12±% 5 joules per terahash (J/TH).
