November 2021 Operational Update

Operational Update

Argo Blockchain plc, a global leader in cryptocurrency mining (LSE: ARB; NASDAQ: ARBK), is pleased to provide the following operational update for November 2021.

During the month of November, Argo mined 185 Bitcoin or Bitcoin Equivalent (together, BTC) compared to 167 BTC in October. This brings the total amount of BTC mined year-to-date to 1,831 BTC.

Based on daily foreign exchange rates and cryptocurrency prices during the month, mining revenue in November amounted to £8.29 million [$11.20 million*] (October 2021: £7.24 million [$9.75 million*]).

Argo generated this revenue at a Bitcoin and Bitcoin Equivalent Mining Margin of approximately 86% for the month of November (October 2021: 86%).

At the end of November, the Company owned 2,317 Bitcoin or Bitcoin Equivalent.

Mining Expansion

As of the end of November, Argo added an additional 310 PH/s to its total capacity, bringing the Company's total mining capacity to 1.605 EH/s as of 30 November, 2021.

Peter Wall, Chief Executive of Argo and interim Chairman said: "Execute. Build. Smart Growth. Onwards and Upwards".

Non-IFRS Measures

Bitcoin and Bitcoin Equivalent Mining Margin is a financial measure not defined by IFRS and has limitations as an analytical tool. 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 realised losses on the sale of digital assets, which affect our IFRS gross profit. This measure should not be considered as an alternative to gross margin determined in accordance with IFRS, or other IFRS measures. This measure is not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider this measure in isolation from, or as a substitute analysis for, our gross margin as determined in accordance with IFRS.

The following table shows a reconciliation of Bitcoin and Bitcoin Equivalent Mining Margin to gross margin, the most directly comparable IFRS measure, for the months of October and November 2021.

(1) Due to favourable changes in fair value of Bitcoin and Bitcoin Equivalents in October 2021, gross profit exceeded revenue.
