December 2022 Operational Update

Argo Blockchain plc, a global leader in cryptocurrency mining (LSE: ARB; NASDAQ: ARBK) is pleased to provide the following operational update for December 2022.

During the month of December, Argo mined 147 Bitcoin or Bitcoin Equivalents (together, BTC) compared to 198 BTC in November 2022. The decrease in BTC mined was primarily due to the curtailment of mining operations at the Helios facility in Dickens County, Texas in response to the widespread winter storm that impacted much of the United States in late December. The Helios facility draws power from the Texas grid and can reduce electricity usage during extreme weather events or times of stress on the grid. During the winter storm, Argo joined other Texas Bitcoin miners in reducing power usage by an estimated 1,500 MW, according to the Texas Blockchain Council. Argo has always committed to being a good community partner, and the Company is proud to have contributed to the stability of the Texas power grid during the winter storm.

As of 31 December 2022, the Company held 141 Bitcoin, of which 116 were Bitcoin Equivalents.

The Company's total hashrate capacity continues to be 2.5 EH/s.

Based on daily foreign exchange rates and cryptocurrency prices during the month, mining revenue in December amounted to $2.49 million [£2.07 million*] (November 2022$3.46 million [£2.94 million*].

Argo generated this income at a Bitcoin and Bitcoin Equivalent Mining Margin of 48% for the month of December (November 2022: 29%).

Sale of Helios to Galaxy

As previously announced on 29 December 2022, the Company closed on a series of agreements with Galaxy Digital Holdings Ltd. (TSX: GLXY) ("Galaxy") to sell its Helios facility to Galaxy for $65 million (£54 million), refinance existing equipment financing loans with a new asset-backed loan from Galaxy in the amount of $35 million (£29 million), and host Argo's mining machines at Helios. The transactions improve the Company's balance sheet and liquidity by reducing total indebtedness by $41 million (£34 million) and improving its cash position. As of 31 December 2022, pro forma for the transactions, the Company's total debt was approximately $79 million (£65 million), and its bank balance was approximately $20 million (£16 million).

The transactions with Galaxy also streamline the Company's operations. Argo maintains ownership of its entire fleet of mining machines, and Galaxy will host the fleet of Bitmain S19J Pro machines at Helios. Additionally, Argo maintains ownership of its two data centers in Quebec, which have a combined power capacity of approximately 20 MW and attractive power prices.

In connection with the sale of Helios and shifting priorities for the Company, Justin Nolan (Chief Growth Officer) and Theodore Papadakis (VP Data Center Operations) have left Argo. Argo is grateful for their contributions to the Company during their tenure and wishes them well in future endeavours.

Management Commentary

Argo's Chief Executive Peter Wall said, "While our mining results for December were lower than anticipated, the primary driver was the winter storm which led us to curtail operations at Helios. We made this decision in order to not only reduce power usage on the grid, but also to prioritise the needs of the local community and safety of our Helios employees. After the winter storm and associated freezing temperatures had subsided, we safely brought Helios back online and resumed operations."

Commenting on the Galaxy transaction, Wall said, "These agreements with Galaxy mark the beginning of a new chapter for Argo. We built a world-class mining facility at Helios, and I believe that Galaxy has the right team and resources to build upon the foundation that Argo established. This deal also allows Argo to continue our mining operations, both at Helios as a hosted customer, as well as at our owned-and-operated facilities in Quebec. I look forward to sharing more details on our growth strategy for 2023 and beyond in due course."

Non-IFRS Measures

Bitcoin and Bitcoin Equivalent Mining Margin is a financial measure not defined by IFRS. We believe Bitcoin and Bitcoin Equivalent Mining Margin 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 gross margin to Bitcoin and Bitcoin Equivalent Mining Margin, the most directly comparable IFRS measure, for the months of November 2022 and December 2022.

(1) Due to unfavourable changes in the fair value of BTC there was a loss on the change in fair value of digital currencies in November 2022. Due to favourable changes in the fair value of BTC there was a gain on the change in fair value of digital currencies in December 2022.
