Vancouver, British Columbia--(Newsfile Corp. - May 24, 2022) - HIVE Blockchain Technologies Ltd. (TSXV: HIVE) (NASDAQ: HIVE) (FSE: HBF) (the "Company" or "HIVE") announces that, further to its press release dated May 10, 2022, the Company will be proceeding with the consolidation (the "Consolidation") of its common shares ("Common Shares") on the basis of five (5) pre-Consolidation Common Shares for one (1) post-Consolidation Common Shares. The Common Shares will commence trading on the TSX Venture Exchange ("TSXV") and Nasdaq on a post-Consolidation basis effective at market opening on May 24, 2022. As of the date hereof, there are 411,209,923 Common Shares issued and outstanding. On a post-Consolidation basis, the Company shall have approximately 82,241,984 Common Shares issued and outstanding. The Company will not be changing its name or stock symbols in connection with the Consolidation. Completion of the Consolidation is subject to the receipt of all necessary regulatory approvals including the approval of the TSX Venture Exchange, and pursuant to the Business Corporations Act (British Columbia) and the articles of the Company. Shareholder approval of the Consolidation is not required.

No fractional Common Shares will be issued as a result of the Consolidation. Any fractional interest in Common Shares that is less than 0.5 of a Common Share resulting from the Consolidation will be rounded down to the nearest whole Common Share, and any fractional interest in Common Shares that is equal to or greater than 0.5 of a Common Share will be rounded up to the nearest whole Common Share.

Registered shareholders will receive a letter of transmittal from the Company's transfer agent, Computershare Investor Services Inc., providing instructions on how to exchange their share certificates representing pre-Consolidation Common Shares for new share certificates or Direct Registration Advice (DRS) representing post-Consolidation common shares to which they are entitled as a result of the Consolidation. No action is required by non-registered shareholders (shareholders who hold their common shares through an intermediary) to affect the Consolidation.

Warrants

There are currently 9,585,250 Common Share purchase warrants originally issued by the Company on November 30, 2021 (the "HIVE Warrants") listed for trading on the TSXV (TSXV: HIVE.WT). As a result of the Consolidation, the number of listed HIVE Warrants outstanding shall not be altered; however, the exercise terms shall be adjusted in accordance with the terms of the warrant indenture dated November 30, 2021, such that on a post-Consolidation basis, five (5) HIVE Warrants shall be exercisable for one (1) post-Consolidation Common Share, upon the payment of an adjusted price of CAD$30.00. Consequently, holders of HIVE Warrants will be entitled to receive one (1) post-Share Consolidation Common Share upon exercising five (5) HIVE Warrants and paying an aggregate of CAD$30.00.

Frank Holmes, Executive Chairman of HIVE stated, "HIVE has accomplished an incredible amount over the past few years. Today we're one of the most profitable and fastest-growing crypto miners in the world."

"Despite our record profitability, HIVE shares trade at around a 2.2 P/E ratio as of May 23, 2022. This share consolidation will allow us to remove some of the penny stock stigma and allow us to engage more institutional investors."

Mr. Holmes continued, "We believe that eventually the market will recognize HIVE's value proposition, but at the same time we accept that further volatility may be in the cards. Either way, we'll continue on with our work. We encourage all shareholders to watch our May 19, 2022, Corporate Update webcast from last week here where we discuss our progress and the benefits to come from the share consolidation."

Darcy Daubaras, CFO of HIVE, added, "Our goal is to efficiently allocate shareholder capital, and we think our track record shows that. Look at our Bitcoin mining operations, which have all been built or acquired over the past 2 years, and now account for roughly 2/3rds of our revenue."

Mr. Daubaras continued, "HIVE remains highly profitable, and this consolidation should create more institutional visibility for our shares."
