FAIRFIELD, Conn., May 15, 2023 /PRNewswire/ -- Greenidge Generation Holdings Inc. (NASDAQ: GREE) ("Greenidge" or the "Company"), a vertically integrated cryptocurrency datacenter and power generation company, today announced financial and operating results for the first quarter of 2023.

"Our results for the first quarter of 2023 are consistent with the estimates we released in April," said Dave Anderson, Chief Executive Officer of Greenidge. "During the first quarter of 2023, we have effectively transitioned our business to a lower risk profile, which has allowed us to continue to participate in the upside of increases to bitcoin prices enabling us to significantly reduce our Adjusted EBITDA loss from continuing operations when comparing to the fourth quarter of 2022 and improving liquidity due to significantly reduced debt service."

First Quarter 2023 Financial Results

Greenidge's revenue for the first quarter was $15.2 million, down 48% compared to the prior year. Cryptocurrency datacenter hosting revenue was $6.9 million as compared to none in the prior year. Cryptocurrency datacenter self-mining revenue was $6.5 million, down 72% versus the prior year as Greenidge transitioned its capacity towards datacenter hosting during the first quarter of 2023. Power and Capacity revenue was $1.8 million, down 70% compared to the prior year. Greenidge's cryptocurrency datacenter operations produced 698 bitcoins during the first quarter, compared to 561 bitcoins in the first quarter of the prior year.

As of March 31, 2023, Greenidge operated approximately 24,700 active miners with an aggregate hash rate capacity of approximately 2.5 EH/s.

Net loss from continuing operations was $8.8 million for the first quarter as compared to $1.7 million in the first quarter of the prior year. Adjusted EBITDA loss for the first quarter was $1.1 million compared to the prior year first quarter Adjusted EBITDA of $7.3 million. The lower average bitcoin prices and higher difficulty levels on the blockchain network in 2023 as compared to 2022 more than offset the increased hash rate capacity. Additionally, a milder winter season in 2023 impacted the year-over-year comparison of profitablilty.

As of March 31, 2023, Greenidge had cash of $17.0 million and debt balance of $97.3 million, which was reduced from $157.5 million as of December 31, 2022.
