For the nine months ended September 30, 2021, the Company's revenue, net income and EBITDA were $67.9 million, $27.1 million and $49.8 million, respectively (£50.4 million, £20.1 million, and £36.9 million, respectively).

"From breaking ground on our sustainable cryptocurrency mining facility in Dickens County, Texas to our public listing on Nasdaq in the United States, this quarter has been pivotal as Argo continues to scale," stated Peter Wall, Chief Executive Officer of Argo Blockchain. "I am proud of the growth we experienced during the quarter and believe Argo is strategically positioned to continue this momentum as we build out our Helios facility in Texas."

Texas Mining Facility Update

In July 2021, Argo broke ground on its renewable energy-focused 200-megawatt (MW) cryptocurrency mining facility in Dickens County, Texas. The new Helios facility will bolster Argo's mining capacity and is expected to add at least 20 new, full-time jobs in Dickens County. The site gives Argo access to up to 800 MW of electrical power and has garnered excitement and support from local community members and government officials.

Bitcoin Mining

During the third quarter, Argo mined 597 Bitcoin and Bitcoin Equivalent (together, BTC), bringing Argo's BTC holding to 1,836 as of September 30, 2021. Argo has been able to achieve these results while maintaining a gross margin of 120% and an industry-leading mining margin of 85% with an average direct cost per BTC mined of $6,293 (£4,673). On September 30, 2021, Argo executed a purchase agreement for 20,000 Bitmain Antminer S19J Pro machines for the mining facility it is building in Texas. The machines are expected to be delivered starting Q2 2022 and will increase our total hashrate capacity to approximately 3.7 Exahash, up from 1.075 at the end of Q3 2021.

(1) Due to favorable changes in fair value of Bitcoin and Bitcoin Equivalents in Q3 2021, gross profit and EBITDA exceeded revenue in the period.

United States Public Listing on Nasdaq

Among the many milestones experienced throughout the quarter, Argo completed its ADR listing on Nasdaq on September 23, 2021. The Company has been publicly listed on the London Stock Exchange since August 2018 and is now listed in both jurisdictions.

Forward-Looking Information

This press release contains forward-looking statements within the meaning of applicable securities laws with respect to our cryptocurrency mining facility in Texas. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that the Company expects, believes or anticipates will or may occur in the future are forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained in this press release specifically include the expectations of plans, strategies, objectives, and anticipated financial and operating results of the Company, including hash rates, the Company's mining program, delivery schedules, future hashrates and other guidance included in this press release. These statements are based on certain assumptions made by the Company based on management's experience and perception of historical trends, current conditions, anticipated future developments and other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. Actual results could differ from those described herein for a variety of reasons, including unanticipated delays in machine delivery due to component supply shortages or other reasons, or disruptions to the Company's current mining fleet that could reduce future hashrate.

Non-IFRS Measures

Bitcoin and Bitcoin Equivalent Mining Margin and EBITDA are financial measures not defined by IFRS. We believe Bitcoin and Bitcoin Equivalent Mining Margin and EBITDA have limitations as analytical tools. In particular, Bitcoin and Bitcoin Equivalent Mining Margin excludes the depreciation of mining equipment and so does not reflect the full cost of our mining operations, and it also excludes the effects of fluctuations in the value of digital currencies and realized losses on the sale of digital assets, which affect our IFRS gross profit. Further, EBITDA excludes interest income (expense), taxes, depreciation and amortization, which are important components of our IFRS net income/(loss). These measures should not be considered as an alternative to gross margin or net income/(loss), as applicable, determined in accordance with IFRS, or other IFRS measures. These measures are not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider these measures in isolation from, or as a substitute analysis for, our gross margin or net income/(loss), as applicable, as determined in accordance with IFRS.
