CASTLE ROCK, Colo., Dec. 04, 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 executed a purchase option and updated its long-term purchase agreement (the “Agreement”) with MicroBT Electronics Technology Co., LTD, through its manufacturing subsidiaries, (“MicroBT”) a prominent manufacturer of Bitcoin miners.
