Vancouver, British Columbia--(Newsfile Corp. - November 16, 2021) - HIVE Blockchain Technologies Ltd. (TSXV: HIVE) (Nasdaq: HIVE) (FSE: HBF) (the "Company" or "HIVE") is pleased to announce a record earnings report for the second quarter ended September 30, 2021 (all amounts in US dollars, unless otherwise indicated).

For the three-month period, revenue rose to $52.6 Million, up 41% compared with last quarter, and 305% since the same quarter last year. Net income reached $59.8 million, up 342% from last quarter, and 549% since the prior year.

HIVE ended the September quarter holding 1,116 Bitcoin ("BTC") worth $48.4 Million and 25,154 Ether ("ETH") worth $74.7 Million.

Frank Holmes, HIVE's Executive Chairman, stated "We wish to thank our loyal shareholders for believing in our vision to mine both Ethereum and Bitcoin to generate robust cash flow returns on invested capital and believe this report validates the significant contribution to our strategy to mine both BTC and ETH and HODL as many coins as possible."

Q2 Quarterly Highlights- September 30, 2021

• Generated revenue from digital currency mining of $52.6 million, with a gross mining margin^[1] of $45.0 million;
• Mined 656 Bitcoin and over 8,688 Ethereum during the three-month period ended September 30, 2021;
• Earned net income of $59.8 million for the period;
• Working capital increased by $29.7 million during the three-month period ended September 30, 2021; and
• Digital currency assets of $123.1 million, as at September 30, 2021

Q2 F2022 Financial Review

For the three months ended September 30, 2021, revenue from digital currency mining was $52.6 million, an increase of approximately 305% from the prior year primarily due to an increase in cryptocurrency prices, the increased production of Bitcoin as a result of the Quebec and Atlantic facility acquisition and the purchase of miners for those facilities.

Gross mining margin¹ during the period was $45.0 million, or 86% of income from digital currency mining, compared to $9.2 million, or 71% of income from digital currency mining, in the same period in the prior year. The Company's gross mining margin from digital currency mining is partially dependent on external network factors including mining difficulty, the amount of digital currency rewards and fees it receives for mining, as well as the market price of digital currencies.

Net income during the quarter ended September 30, 2021, was $59.8 million, or $0.16 per share, compared to $9.2 million, or $0.03 per share, the same period last year. The improvement was driven primarily by the improvement in gross mining margin¹, higher Ethereum and Bitcoin prices, gains on the sale of digital currencies, and foreign exchange.

Construction and Capital Investment

The Company is nearing completion of two additional data centres at its New Brunswick, Canada campus. Construction began on this site in July 2021 and has progressed largely on schedule, despite supply chain delays. The first of the two new data centers is expected to be commissioned by mid-December 2021, and the second in March 2022.

During the second fiscal quarter, HIVE invested heavily in new Bitcoin miners to fill up these new data centres. At quarter-end, the company had more than 16,000 new BTC miners on order. And since then, the Company has announced a C$100 million capital raise to invest in new Bitcoin mining equipment.

Frank Holmes, HIVE Executive Chairman, stated, "I'm pleased to see our infrastructure investments of the past few years really paying off. We feel like HIVE is in a fantastic spot to benefit from the current boom in crypto adoption."

About HIVE Blockchain Technologies Ltd.

HIVE Blockchain Technologies Ltd. went public in 2017 as the first cryptocurrency mining company with a green energy and ESG strategy.

HIVE is a growth-oriented technology stock in the emergent blockchain industry. As a company whose shares trade on a major stock exchange, we are building a bridge between the digital currency and blockchain sector and traditional capital markets. HIVE owns state-of-the-art, green energy-powered data centre facilities in Canada, Sweden, and Iceland, where we source only green energy to mine on the cloud and HODL both Ethereum and Bitcoin. Since the beginning of 2021, HIVE has held in secure storage the majority of its ETH and BTC coin mining rewards. Our shares provide investors with exposure to the operating margins of digital currency mining, as well as a portfolio of cryptocurrencies such as ETH and BTC. Because HIVE also owns hard assets such as data centers and advanced multi-use servers, we believe our shares offer investors an attractive way to gain exposure to the cryptocurrency space. HIVE traded over 2 billion shares in 2020.

"Forward-looking information" in this news release includes information about restructuring of the Company's operations and sustainable future profitability; potential further improvements to the profitability and efficiency across mining operations by optimizing cryptocurrency mining output, continuing to lower direct mining operations cost structure, and maximizing existing electrical and infrastructure capacity including with new mining equipment in existing facilities; continued adoption of Ethereum and Bitcoin globally; the potential for the Company's long term growth; the business goals and objectives of the Company, and other forward-looking information includes but is not limited to information concerning the intentions, plans and future actions of the parties to the transactions described herein and the terms thereon.

Factors that could cause actual results to differ materially from those described in such forward-looking information include, but are not limited to, the efficiencies obtained through restructurings may not lead to operational advantages or profitability; further improvements to the profitability and efficiency may not be realized as currently anticipated, or at all; the digital currency market; the Company's ability to successfully mine digital currency; the Company may not be able to profitably liquidate its current digital currency inventory, or at all; a decline in digital currency prices may have a significant negative impact on the Company's operations; the volatility of digital currency prices; and other related risks as more fully set out in the Filing Statement of the Company dated and other documents disclosed under the Company's filings at www.sedar.com.

This news release also contains "financial outlook" in the form of gross mining margins, which is intended to provide additional information only and may not be an appropriate or accurate prediction of future performance and should not be used as such. The gross mining margins disclosed in this news release are based on the assumptions disclosed in this news release and the Company's Management Discussion and Analysis for the fiscal year ended March 31, 2021, which assumptions are based upon management's best estimates but are inherently speculative and there is no guarantee that such assumptions and estimates will prove to be correct.

The forward-looking information in this news release reflects the current expectations, assumptions and/or beliefs of the Company based on information currently available to the Company.

The Company has also assumed that no significant events occur outside of the Company's normal course of business. Although the Company believes that the assumptions inherent in the forward-looking information are reasonable, forward-looking information is not a guarantee of future performance and accordingly undue reliance should not be put on such information due to the inherent uncertainty therein.
