• Strong quarterly revenue of $43.8 million
• Bitcoin holdings increased 14.6% to 7,406 in Q2
• Achieved adjusted EBITDA⁽ⁱ⁾ of $6.8 million

Hut 8 Mining Corp. (Nasdaq: HUT) (TSX: HUT), ("Hut 8" or the "Company") one of North America's largest, innovation-focused digital asset mining pioneers and high performance computing infrastructure provider, is pleased to announce its financial results for the quarter ended June 30, 2022. All dollar figures are in Canadian Dollars ("CAD"), unless otherwise stated.

"We have been anticipating market volatility for nearly a year and took proactive measures to successfully navigate the current downturn through the balance of the cycle," said Jaime Leverton, CEO of Hut 8. "Our continued growth in digital asset mining operations and in our Bitcoin reserves, coupled with our first full quarter generating uncorrelated fiat revenue in our high performance computing business, has positioned us well to drive future success."

"Our operational orientation and conservative, balance sheet first approach continued to serve us well in the second quarter," said Shane Downey, CFO of Hut 8. "We generated strong revenue in our digital asset mining business, made strides in solidifying and growing our high performance computing business and remain focused on the continued health of the company overall."

• Revenue increased by $10.3 million to $43.8 million compared to $33.5 million for the quarter ended June 30, 2021 ("Q2 2021").
• The Company mined 946 Bitcoin in the quarter ended June 30, 2022 ("Q2 2022"), a 71% increase compared to the same period in 2021 due to an increase in hashrate from additional highly efficient miners and initial ramping of activities at Hut 8's third mining site in North Bay, Ontario.
• Hut 8's high performance computing operations generated $4.7 million of revenue in the quarter, the majority of which is monthly recurring revenue.
• Hut 8's mining site in North Bay, Ontario has been gradually ramping up with approximately 20 MW of power and approximately 5,800 miners installed as of June 30, 2022, which are adding approximately 565 PH/s to Hut 8's mining capacity.
• The Company installed 7,199 new MicroBT M30S, M30S+, and M31S+ miners at the Drumheller, Alberta, Medicine Hat, Alberta, and North Bay, Ontario facilities during Q2 2022. The installation of these miners brought Hut 8's operating capacity to 2.78 EH/s as of June 30, 2022, an increase of 9% in hashrate compared to March 31, 2022.
• The Company further strengthened its executive team with the appointment of Aniss Amdiss as Chief Legal Officer, effective July 11, 2022.

Revenue for Q2 2022, was $43.8 million compared to $33.5 million in Q2 2021. The increase was primarily driven by the Company's digital asset mining operations, where the Company mined 946 Bitcoin and generated $39.1 million of revenue, versus 553 Bitcoin mined and $31.4 million of revenue in Q2 2021. The increase in Bitcoin mined is due to the significant increase in Hut 8's average hashrate stemming from the expansion of the Company's highly efficient mining fleet and ramp-up activities of the Company's new site in North Bay, Ontario. The Company's newly-acquired high performance computing operations generated $4.7 million of primarily recurring revenue in the quarter.

Net loss for Q2 2022 was $88.1 million and net loss per share was $0.49, compared to net loss of $4.0 million and net loss per share of $0.03 for the same period in 2021. The change reflects the non-cash revaluation loss on digital assets, partially offset by higher revenue and the non-cash revaluation gain on warrants liability.

Mining profit⁽ⁱ⁾ was $14.9 million in Q2 2022, compared to $19.3 million in Q2 2021. The change is mainly due to a lower average Bitcoin price and increased average power costs, which were partially offset by the revenue associated with the higher number of Bitcoin mined.

Adjusted EBITDA⁽ⁱ⁾ was $6.8 million, compared to $14.4 million in Q2 2021. Increased revenues from mining operations and contributions from high performance computing operations were offset by compressed mining margins due to lower average Bitcoin price and higher general and administrative expenses incurred to support the growth in Hut 8's mining and high performance computing operations.

Cost of revenue consists of site operating costs and depreciation and was $47.7 million for Q2 2022 compared to $16.6 million in Q2 2021. Site operating costs for the quarter ended June 30, 2022, was $26.8 million, of which $24.5 million was attributable to our mining operations and $2.3 million to our high performance computing operations. The average cost of mining each Bitcoin for Q2 2022 was approximately $25,900, compared to approximately $24,700 per Bitcoin in Q2 2021. The increase in average cost of mining Bitcoin was primarily due to higher power prices, partially offset by the deployment of a more efficient mining fleet. Depreciation expense increased to $20.9 million during Q2 2022 compared to $3.0 million in Q1 2021, driven by the significant deployment of new mining equipment over the past twelve months as well as $1.3 million of additional depreciation from our newly acquired high performance computing operations.

Mining Profit

"Mining profit" represents gross profit (revenue less cost of revenue), excluding depreciation and revenue and site operating costs directly attributable to hosting services and high performance computing operations. Mining profit shows profitability of the Company's core digital asset mining operation, without the impact of non-cash depreciation expense. Mining profit measure provides the investors the ability to assess the profitability of the mining operations exclusive of general and administrative expenses.

Adjusted EBITDA

"Adjusted EBITDA" represents EBITDA (net income or loss excluding net finance income or expense, income tax or recovery, depreciation, and amortization) adjusted to exclude non-cash share-based compensation, fair value gain or loss on revaluation of digital assets and warrants, non-recurring impairment charges or reversals of impairment, and costs associated with one-time or non-recurring transactions. Adjusted EBITDA is used to assess profitability without the impact of non-cash accounting policies, capital structure and one-time or non-recurring transactions. This performance measure provides a consistent comparable metric for profitability of the Company across time periods.

Hut 8 anticipates that based on the current installed hashrate and scheduled deliveries of new miners, the Company will reach 3.55 EH/s organically by the end of 2022.

As part of the Company's ongoing integration of the recently acquired high performance computing operations, Hut 8 rationalized certain low-margin product and service offerings during the second quarter. Hut 8 believes these improvements will better position the Company to realize profitable revenue growth in 2023. As a result, the Company has withdrawn the revenue growth guidance provided in its Q1 2022 results.

Hut 8's Q2 2022 conference call will begin at 10 a.m. ET on August 11, 2022. Those wishing to join via telephone should dial in 5 minutes early:
