Summary Overview:

• HIVE produced 260 Bitcoin in the month of January, from ASIC and GPU mining operations, representing an average of 110 Bitcoin Per Exahash. A 21% month over month increase, compared to December 2022 (214 Bitcoin produced).
• HIVE's year over year monthly Bitcoin production was consistent (260 Bitcoin in January 2023 and 264 Bitcoin in January 2022), during a period where the Bitcoin network difficulty increased approximately 60%.
• HIVE earned USD $180,000 in income from balancing the grid, in addition to Bitcoin produced in January. Based on the daily Bitcoin prices during the month of January, the income from grid balancing would equate to a mined value of 10 Bitcoin.
• HIVE deployed over 6,700 new generation ASIC miners in its data centers, representing one of the largest upgrades in the Company's history, to improve our gross mining margin and fleet efficiency.
• HIVE has deployed over 3,200 BuzzMiners in its facilities in Sweden and Canada. These miners are from the 5,655 BuzzMiners manufactured, tested, and received to date.
• HIVE has fully deployed all the 3,570 S19j Pro miners acquired in December 2022 into our New Brunswick and Lachute facilities. As a result of in-house software improvements by HIVE's technical team, we further increased our efficiency at our New Brunswick site by approximately 20% in average J/TH efficiency.
• HIVE expects to receive an additional 645 BuzzMiners in the next 2 months, representing a total production quantity of 6,300 BuzzMiners powered by the Intel Blockscale ASIC for the initial production run. HIVE is the first company in the world to commercially deploy thousands of its own Bitcoin ASIC miners powered by the Intel Blockscale ASIC.
• HIVE sells all of the Bitcoin earned from our GPU mining hashrate, with a focus to HODL the green Bitcoin mined from ASICs.

January 2023 Production Figures

Frank Holmes, Executive Chairman of HIVE stated, "We are very happy to have overcome several big headwinds over the past year such has Bitcoin prices falling 50%, the Global Difficulty surging 50% which means fewer coins mined unless you increase both the efficiency of ASIC chips and number of machines mining which HIVE has done. Even with huge headwinds like the FTX bankruptcy and contagion, the HIVE management team has stayed focused and increased its BTC production and our HODL Bitcoin position. Further we have pivoted with our GPU chips away from Ethereum after the Merge and are using Ai to mine alternative coins and convert into Bitcoin, thus we are able to generate Bitcoin revenue. We have decided to sell the BTC earned using GPU/Ai and strive to HODL our Bitcoins created from hydro and geothermal electricity. We have not been using our ATM since November 30, 2022, and have been able to create other sources of revenue from balancing the grid to selling back energy while deploying the new Intel BuzzMiners and purchased other highly efficient ASIC machines from internal cash management. Our financial success has been from our company's values, culture, and strategy to have propriety software and strong global partnerships. Finally and fortunately we never borrowed at predatory 12-18% interest rates or kept our Bitcoin in crypto exchanges and I am very proud of the team's agility to adapt thoughtfully and quickly to the many external crisis's through the crypto winter bear market of 2022."

Aydin Kilic, President & CEO of HIVE noted "We are proud to be producing 260 Bitcoin while also earning over USD $180,000 this month from our grid balancing initiatives. Our team has deployed over 6,700 ASIC miners in our data centers, including over 3,200 HIVE BuzzMiners, powered by the Intel Blockscale ASIC and all of the 3,570 S19j Pros we acquired in December 2022. HIVE was the first public crypto mining company to realize income from its grid balancing program in Sweden. We view grid balancing as part of our core strategy, and whenever possible, we seek to hedge energy prices."

Mr. Kilic continued, "We have increased our overall hashrate by 25% month over month from December 2022 to January 2023. We are continuously looking to optimize our allocation of energy as a resource, either to generate hashrate or sell energy back to the grid. Moreover, if unhedged spot prices are uneconomical in a specific jurisdiction, we quickly scale down our production. Additionally, our remaining GPU fleet is now generating approximately USD $80/MWHR in revenue, which is similar to the USD $/MWHR compared to Bitcoin ASIC miners in the current Bitcoin mining economics. We are constantly optimizing the deployment of our technology resources as a company to optimize profit. These advancements and agility allow us to generate positive gross mining margin during a crypto mining bear market. With a strong balance sheet of over USD $56 million of Bitcoin, HIVE is well positioned in the market today."

The Company's total Bitcoin production in January 2023 was:

• 260 BTC produced;
• 8.4 BTC produced per day on average;
• 2.68 Exahash of BTC Hashrate (BTC ASIC hashrate plus BTC GPU Hashrate) as of January 31, 2023 comprised of 2.52 Exahash of ASIC BTC hashrate and 0.16 Exahash of GPU BTC Hashrate (the GPU fleet was curtailed to earn income for grid balancing) as of January 31^st; and
• Monthly average of 2.37 Exahash, which is equal to 110 Bitcoin per Exahash, comprised of an average of 2.28 Exahash of ASIC mining capacity and an average of 90 PH/s of Bitcoin GPU mining capacity during the month.

Bitcoin HODL Update

As of the date of this press release, HIVE has approximately 2,430 Bitcoin, with a market value of over USD $56 million.

Bitcoin Global Network Mining Difficulty Is Volatile

Network difficulty factors are a significant variable in the Company's gross profit margins. The Bitcoin network difficulty was 34.1T as at January 1, 2023 and increased to 39.4T as at January 31, 2023. Accordingly, Bitcoin mining difficulty ended the month about 15% higher than the beginning of the month.

The Bitcoin Network Difficulty is a publicly available statistic, that reflects the total number of Bitcoin miners online and is important in analyzing a company's gross profit margins, and number of Bitcoin produced. This data is available on many websites, here is one citation: https://www.blockchain.com/explorer/charts/difficulty

As more people mine Bitcoin (difficulty increases), the daily Bitcoin block reward which presently is fixed at 900 Bitcoin per day, gets split amongst more miners; thus each miner receives a smaller portion of the block reward. Conversely, as Bitcoin prices fall, many miners may lose money, and power down, thus taking their hashrate off the network, causing Network Difficulty to decrease.

Those miners with the lowest costs of production; by virtue of having more efficient machines and/or lower energy costs, are able to continue their production during these volatile cycles. Not all miners will continuously mine during a given month. As a result, some miners will produce less Bitcoin than expected, relative to their advertised hashrate. For the foregoing reasons, HIVE will self-curtail part of its operations if the unhedged spot energy prices are uneconomical, thereby leaving part of its total gross hashrate unutilized.

All Bitcoin miners are striving to use the most efficient Bitcoin ASIC chips, and we are happy that we have been able to upgrade our global fleet during this crypto market downturn.

ATM Equity Program Update

Effective as of the date hereof, the Company has terminated its at-the-market equity distribution agreement under which the Company had the option to sell up to USD $100 million of common shares of the Company at its discretion (the "ATM Equity Program"). The Company did not offer any shares under the ATM Equity Program after November 30, 2022. From inception of the ATM Equity Program to November 30, 2022, the Company issued 1,306,474 common shares (the "ATM Shares") for gross proceeds of USD $3,941,736. The ATM Shares were sold at prevailing market prices. A cash commission of USD $118,252 on aggregate gross proceeds from the ATM Equity Program was paid to the Company's sales agent.
