Exhibit 99.1

RIOT PURCHASES 7.6 EH/S OF NEXT GENERATION MINERS FROM MICROBT, MANUFACTURED IN THE UNITED STATES

Landmark deal includes an initial purchase of 33,280 miners to increase self-mining capacity to 20.1 EH/s upon full deployment in 2024. Agreement also includes an option to purchase up to 66,560 additional miners at same terms.

CASTLE ROCK, CO. / Globe Newswire / June 26 2023 / Riot Platforms, Inc. (NASDAQ: RIOT) (“Riot” or, the “Company”), an industry leader in Bitcoin (BTC) mining and data center hosting, announced today that it has entered into a long-term purchase agreement (the “Agreement”) with MicroBT Electronics Technology Co., LTD, through its manufacturing subsidiaries, (“MicroBT”) a prominent manufacturer of Bitcoin miners with production facilities in the United States. Under the Agreement, Riot has secured an initial order of 33,280 next-generation Bitcoin miners from MicroBT. The miners will be produced by MicroBT in the United States for Riot’s Corsicana Facility, for total consideration of $162.9 million (exclusive of applicable taxes and fees and adjustments), equating to approximately $21.50 per terahash (TH).

The Agreement provides delivery of the new miners starting in December 2023, with miner deployment planned to begin in Q1 2024. Upon full deployment of the 33,280 miners ordered, which is anticipated to be completed by mid-2024, Riot’s self-mining hash rate capacity is expected to increase to 20.1 EH/.

Initial Order Summary
Model	# of Units	Hashrate (TH/s)	Efficiency (Joules/TH)
M56S+	8,320	220.0	24.0
M56S++	24,960	230.0	22.0
Total/Weighted Average	33,280	7.6 EH/s	22.5

Riot has also secured the option to purchase up to 66,560 additional M56S++ miners from MicroBT, on the same terms as the initial order, under the Agreement. Assuming full exercise of Riot’s option, the 66,560 additional miners would add 15.3 EH/s to Riot’s self-mining capacity, to a potential total of 35.4 EH/s. Riot may execute the option, in whole or in part, through December 31, 2024.

“Riot is excited to announce our first order of Bitcoin miners for our Corsicana Facility from MicroBT,” said Jason Les, CEO of Riot. “These new models are among the most powerful and efficient miners ever made for Bitcoin mining and are designed and produced specifically for immersion cooling systems, such as those that will be used at our Corsicana Facility. These new miners will contribute an additional 7.6 EH/s to Riot’s self-mining capacity when fully deployed and will further enhance our already strong fleet efficiency in advance of the upcoming Bitcoin halving.”

In addition, Riot and MicroBT’s new partnership will secure a robust domestic supply chain in the United States, increasing domestically produced options for Bitcoin miners and marking a significant milestone for the industry. MicroBT will manufacture these miners at a facility in Pittsburgh, PA, which will lead to the creation of new, highly skilled jobs in the local area.

“Riot is thrilled to establish this relationship with MicroBT for onshore manufacturing and to secure this critical supply chain for our business,” continued Riot CEO Jason Les.

“The announcement of this significant order from Riot is a major milestone in MicroBT’s history,” said Jordan Chen, COO of MicroBT. “The M56S+ and M56S++ are the most powerful machines we have ever developed and represent the culmination of major technological advancements made by our engineering teams. All machines purchased by Riot will be manufactured in our facility in the United States, and this order will drive expansion of our operations allowing us to hire and train new staff to fulfill our growing United States-based manufacturing business.”
