The MD&A is provided as a supplement to, and should be read in conjunction with, our consolidated financial statements and notes thereto included in Item 8 - Financial Statements and Supplementary Data. The MD&A generally discusses 2021 and 2020 items and year-to-year comparisons between 2021 and 2020, as well as year-to-year discussions between 2021, 2020, and 2019, where indicated. Discussions of 2019 items and year-to-year comparisons between 2020 and 2019 that are not included in this Form 10-K/A can be found in "Management's Discussion and Analysis of Financial Condition and Results or Operations" in the Company's Annual Report on Form 10-K for the fiscal year endedDecember 31, 2020 , filed with theSEC onMarch 31, 2021 .
Business Overview:
We are a vertically integrated Bitcoin mining and cryptocurrency infrastructure development company principally engaged in enhancing our capabilities to mine Bitcoin. We also provide the critical mining infrastructure for our institutional scale clients to mine Bitcoin at our Bitcoin mining facility (the "Whinstone Facility"). Our Whinstone Facility is believed to be the largest Bitcoin mining facility, as measured by developed capacity, inNorth America .
We operate in an environment which is consistently evolving based on the proliferation of Bitcoin and cryptocurrencies in general. A significant component of our strategy is to effectively and efficiently allocate capital between opportunities that generate the highest return on capital.
We operate in three business segments: (1) Bitcoin Mining ("Mining"), (2) Data Center Hosting ("Hosting"), and (3) Electrical Products and Engineering ("Engineering").
Strategic Acquisitions Whinstone OnMay 26, 2021 , we completed the acquisition of all of the issued and outstanding equity interests inWhinstone US, Inc. ("Whinstone") pursuant to the stock purchase agreement, dated as ofApril 8, 2021 , we entered into with Northern Data AG ("Northern Data") and Whinstone (the "Whinstone Acquisition"). At the closing of the Whinstone Acquisition, we paid to Northern Data$80 million in cash, subject to customary adjustments set forth in the stock purchase agreement, and issued to Northern Data 11.8 million shares of our common stock. We also entered into a shareholder agreement with Northern Data on the closing date granting Northern Data certain registration rights whereby we registered the 11.8 million shares issued to Northern Data as part of the Whinstone Acquisition. Subsequent toDecember 31, 2021 , there were no registration rights obligations to Northern Data. 32 After closing the Whinstone Acquisition, we announced a large-scale expansion of the Whinstone Facility by 400 MW, which is anticipated to bring the Whinstone Facility to 700 MW in total capacity of Bitcoin mining infrastructure. The expansion of the Whinstone Facility will provide us with the necessary infrastructure to operate our miners efficiently, and deploy our future miners, as well as provide additional expansion opportunities in our Hosting business.
ESS Metron
OnDecember 1, 2021 , we entered into a membership interest purchase agreement to acquire all of the issued and outstanding equity interests (the "ESS Metron Acquisition") ofFerrie Franzmann Industries, LLC (d/b/a ESS Metron) ("ESS Metron"). At the closing of the ESS Metron Acquisition, we issued to the sellers$25 million in cash, subject to customary adjustments set forth in the membership interest purchase agreement, and 715,413 shares of our common stock, subject to a holdback of 70,165 shares as security for the sellers' indemnification obligations under the membership interest purchase agreement. We also granted the sellers certain registration rights relating to the resale by the sellers of the shares issued to them under the membership interest purchase agreement, among other things. Pursuant to these registration rights, we registered the resale of the 645,248 shares issued to the sellers at the closing of the ESS Metron Acquisition pursuant to the prospectus supplement we filed with theSEC onDecember 1, 2021 under our effective Registration Statement on Form S-3 filed with theSEC onAugust 31, 2021 (File No. 333-259212). These registration rights also apply to the 70,165 holdback shares withheld at closing of the ESS Metron Acquisition, subject to the satisfaction of the conditions to their release, as set forth in the membership interest purchase agreement. Accordingly, as provided in the membership interest purchase agreement, we will be obligated to register under the Securities Act the resale of the holdback shares that are ultimately issued to the sellers. ESS Metron is one of the world's leading designers and manufacturers of power distribution equipment. The acquisition of ESS Metron provides critical infrastructure electrical components and engineering expertise to facilitate the expansion of our Whinstone Facility, as well as future strategic growth initiatives we may undertake. ESS Metron has also been instrumental in the design, manufacture, and implementation of our industrial-scale immersion-cooled Bitcoin mining hardware at our Whinstone Facility. 2022 Trends We anticipate that 2022 will be a year of consolidation in the Bitcoin mining industry, and we believe that, given our relative position in the competitive landscape, we are likely positioned to benefit from this consolidation. As a result of any strategic action undertaken by us, our business and financial results may change significantly. We are continuously evaluating strategic opportunities we may decide to undertake as part of our strategic growth initiatives; however, we can offer no assurances that any strategic opportunities we decide to undertake will be achieved on the schedule or within the budget we anticipate, if at all, in our competitive and evolving industry. See Part I, Item 1A. "Risk Factors" of this Annual Report for additional discussion regarding potential impacts our competitive and evolving industry may have on our business. Bitcoin Mining AtDecember 31, 2021 , our Mining business operated approximately 30,907 ASIC miners, with a hash rate capacity of 3.1 exahash per second ("EH/s"), utilizing approximately 96 megawatts ("MW") of capacity. In 2021, we mined 3,812 Bitcoin, which represented an increase of 269% over the 1,033 Bitcoin we mined in 2020. Based on our existing operations and expected deliveries of miners pursuant to our purchase orders with their manufacturer, Bitmain, we anticipate we will have approximately 120,150 miners in operation, utilizing approximately 370 MW of capacity by the end of 2022. 33
Miner Purchases and Deployments
AtDecember 31, 2021 , we had purchased, received and/or deployed the following miners: Number of miners
Miners deployed atJanuary 1, 2021

Total miners under contract, expected to be received, or deployed atDecember 31, 2022 120,146 During 2021, we received 34,608 additional Antminer model S19-Pro miners pursuant to purchase orders with their manufacturer, Bitmain, and, as ofDecember 31, 2021 , we had deployed a total of 30,907 miners in our Mining operation. Additionally, we executed six additional purchase orders with Bitmain to acquire 43,500 Antminer model S19j (90 Terahash per second) ("TH/s")) miners, and 9,000 Antminer model S19j-Pro (100 TH/s) miners, and 30,000 of Bitmain's latest generation Antminer model S19XP (140 TH/s) miners, for a combined total purchase price of approximately$535.0 million . Pursuant to these agreements, approximately$301.3 million remains payable to Bitmain in installments in advance of shipment of the miners, which is scheduled to occur on a monthly
basis throughDecember 2022 . Data Center Hosting
Upon completion of the Whinstone Acquisition, we commenced an expansion of our Whinstone Facility to 700 MW, from its existing 300 MW of developed capacity. We expect the expanded Whinstone Facility to be completed during 2022, including the construction of four new dedicated Bitcoin mining buildings totaling approximately 240,000 square feet of finished hosting space. Upon completion, we anticipate our Whinstone Facility will possess sufficient developed electricity power capacity to support an estimated 112,000 Antminer model S19j miners based upon current configurations. We believe the expansion of our Whinstone Facility will provide sufficient capacity to enable us to deploy a significant quantity of our miners (including our current deployed fleet and those expected to be delivered in future shipments pursuant to our purchase orders with Bitmain) in a self-hosted facility, while allowing Whinstone to continue to operate and grow its existing Hosting business. We believe deploying our miners at the expanded Whinstone Facility has many advantages for our mining operations, including allowing us to operate our miners without incurring third-party colocation services fees and to do so at the fixed low energy costs available to the Whinstone Facility under its long-term power supply agreement. We also anticipate this expansion of the Whinstone Facility will provide space for third-party miner colocation services and for other enterprise-level data center hosting services. Whinstone currently hosts Bitcoin mining operations for institutional-scale mining customers. In addition to Hosting revenue from customers, Whinstone also generates, as part of its Hosting revenue, construction services revenue from hosting customers on site, including revenue derived from the fabrication and deployment of immersion-cooling technology for Bitcoin mining. From theMay 26, 2021 acquisition date throughDecember 31, 2021 , Hosting revenue and net income was approximately$24.5 million and$1.2 million , respectively. Additionally, the majority of our$22.6 million of deferred revenue as ofDecember 31, 2021 is related to advance payments made by Whinstone customers, which will be primarily recognized over the remaining lives of the underlying contracts, or approximately eight years.
Electrical Products and Engineering
The Acquisition of ESS Metron provides us with the ability to vertically integrate many of the critical electrical components and engineering services necessary for our Whinstone expansion. A key component of our strategy is to integrate the expertise of the ESS Metron team, which we believe is necessary to reduce our execution and counter-party risk in ongoing and future expansion projects. ESS Metron's engineers will also allow us to continue to explore new methods to optimize and develop a best-in-class Bitcoin mining operation, and they have been instrumental in the development of our industrial-scale immersion-cooled Bitcoin mining hardware. ESS Metron also has an existing electricity distribution product design, manufacture, and installation business primarily focused on large-scale commercial and governmental customers. 34 COVID-19 The COVID-19 global pandemic has been unpredictable and unprecedented and is likely to continue to result in significant national and global economic disruption, which may adversely affect our business. Based on our current assessment, however, we do not expect any material impact on our long-term development, our operations, or our liquidity due to the worldwide spread of COVID-19, other than the potential impacts of COVID-19 on global logistics discussed below. We are actively monitoring this situation and the possible effects on our financial condition, liquidity, operations, suppliers, and industry. Global Logistics Global supply logistics have caused delays across all channels of distribution. Similarly, we have also experienced delays in certain of our miner delivery schedules. During 2021, we have been able to effectively mitigate any delivery delays to avoid materially impacting our miner deployment schedule, however, there are no assurances we will be able to continue to mitigate any such delivery delays in 2022. Additionally, the scale of the Whinstone expansion requires large quantities of specific materials. We have procured and hold many of the required materials to help mitigate against global supply logistic and pricing concerns. We monitor developments in the global supply chain and how that may potentially impact our expansion plans. See Part I, Item 1A. "Risk Factors" of our Annual Report for additional discussion regarding potential impacts the global supply chain crisis may have on our operations and plans
for expansion.

Results of Operations Comparative Results for the Years Ended
Revenues: Total revenue for the years endedDecember 31, 2021 and 2020, was$213.2 million and$12.1 million , respectively, and consisted of our Mining revenue, Hosting revenue, Engineering revenue, and other revenue. For the years endedDecember 31, 2021 and 2020, Mining revenue was$184.4 million , and$12.0 million , respectively. The increase of$172.4 million in mining revenue was due to higher Bitcoin values in the 2021 period, averaging$45,744 per coin as compared to$11,461 per coin in the 2020 period, combined with a higher number of Bitcoin mined in 2021, which totaled 3,812, as compared to 1,033 in the 2020 period. For the period from the acquisition of Whinstone onMay 26, 2021 toDecember 31, 2021 , Hosting revenue was$24.5 million , and there was no Hosting revenue for the year endedDecember 31, 2020 . Hosting revenue includes upfront payments, which we record as deferred revenue and generally recognize as services are provided. We provide energized space and operating and maintenance services to third-party mining companies who locate their mining hardware at our Whinstone Facility under long-term contracts. We account for these agreements as a single performance obligation for services being delivered in a series with delivery being measured by daily successful operation of the mining hardware. As such, we recognize revenue over the life of the contract as its series of performance obligations are met. The contracts are recognized in the amount for which we have the right to invoice because we elected the "right to invoice" practical expedient. For the period from the acquisition of ESS Metron onDecember 1, 2021 toDecember 31, 2021 , Engineering revenue was$4.2 million , and there was no Engineering revenue for the year endedDecember 31, 2020 . Engineering revenue is derived from the sale of custom products built to customers' specifications under fixed-price contracts with one identified performance obligation. Engineering revenues are recognized over time as performance creates or enhances an asset with no alternative use, and for which the Company has an enforceable right to receive compensation as defined under the contract.
Other revenue consisting of license fees earned from our legacy animal bioscience business was not significant in either period.
Costs and expenses:
Cost of revenues for Mining for the years endedDecember 31, 2021 and 2020 was$45.5 million and$6.3 million , respectively, representing an increase of approximately$39.2 million . As a percentage of Mining revenue, cost of revenues totaled 24.7% and 52.2% for each of the years endedDecember 31, 2021 and 2020, respectively. Cost of revenues consist primarily of direct production costs of mining operations, including electricity, labor, insurance and, in 2020, rent for theOklahoma City facility and, in 2021, the variableCoinmint hosting fee, but excluding depreciation and amortization which are separately stated. The increase of$39.2 million in cost of revenues is primarily due to the increases in variable mining costs, including the variable hosting fees associated with increases in mining revenues. Cost of revenues for Hosting for the period from the acquisition of Whinstone onMay 26, 2021 toDecember 31, 2021 was$33.0 million and there were no Hosting costs for the year endedDecember 31, 2020 . The 2021 costs consisted primarily of$25.8 million for direct power costs, with the balance primarily incurred for compensation and rent costs.
Cost of revenues for Engineering for the period from the acquisition of ESS Metron onDecember 1, 2021 toDecember 31, 2021 was$3.6 million and there were no Engineering costs for the year endedDecember 31, 2020 . The 2021 costs consisted primarily of$3.6 million for direct materials and labor, as well as indirect manufacturing costs. Acquisition-related costs for the year endedDecember 31, 2021 totaled$21.2 million and consisted of expenses incurred in connection with our acquisitions of Whinstone and ESS Metron. There were no acquisition-related costs for the year endedDecember 31, 2020 . 36 Selling, general and administrative expenses during the years endedDecember 31, 2021 and 2020 totaled$87.4 million and$10.3 million , respectively. Selling, general and administrative expenses consist of stock-based compensation, legal and professional fees and other personnel and related costs. The increase of$77.2 million is primarily due to an increase in stock-compensation expense of$65.1 million resulting from additional awards (including the performance-based plan announced inAugust 2021 ), compensation expense, which increased by$5.7 million due to additional employees to support the Company's growth, and an increase in consulting fees of$2.6 million resulting primarily from assistance on internal control systems and procedures. Depreciation and amortization expense during the year endedDecember 31, 2021 totaled$26.3 million , which is an increase of approximately$21.8 million , as compared to$4.5 million for the year endedDecember 31, 2020 . The increase is primarily due to higher depreciation expense recognized for the Whinstone Facility and our recently acquired miners. Change in fair value of our derivative asset for the period from the acquisition of Whinstone toDecember 31, 2021 , was$18.6 million , including$12.1 million recorded to adjust the fair value of our Power Supply Agreement, which was classified as a derivative asset and measured at fair value on the date of our acquisition of Whinstone, and$6.5 million from power sales toERCOT through its demand response programs. There were no derivative assets for the year endedDecember 31, 2020 . Impairment of long-term investments of$9.4 million recognized during the year endedDecember 31, 2020 was recorded in connection with the impairment of our investment inCoinsquare Ltd. , a Canadian cryptocurrency exchange ("Coinsquare"). Impairment of cryptocurrencies for the years endedDecember 31, 2021 and 2020 was$36.5 million and$1.0 million respectively, arising from the decline in Bitcoin prices during the periods. Other Income: Other income for the years endedDecember 31, 2021 and 2020 was$14.7 million and$1.5 million , respectively. The increase of$13.2 million is primarily related to a$26.3 million realized gain on the sale/exchange of long-term investment recognized in connection with the exchange of our shares of Coinsquare, partially offset by a$13.7 million unrealized loss on the decline in fair value our marketable equity securities.
Income Taxes:
For the year endedDecember 31, 2021 the Company recorded an income tax expense of$0.3 million . There was no income tax expense or benefit recorded for the year endedDecember 31, 2020 .
Non-GAAP Measures
In addition to consolidatedU.S. GAAP financial measures, we consistently evaluate our use and calculation of the non-GAAP financial measure, "Adjusted EBITDA." Adjusted EBITDA is a financial measure defined as our EBITDA, adjusted to eliminate the effects of certain non-cash and / or non-recurring items, that do not reflect our ongoing strategic business operations. EBITDA is computed as net income before interest, taxes, depreciation, and amortization. Adjusted EBITDA is EBITDA further adjusted, for certain income and expenses, management believes results in a performance measurement that represents a key indicator of the Company's core business operations of Bitcoin mining. The adjustments include fair value adjustments such as derivative power contract adjustments, equity securities value changes, and non-cash stock-based compensation expense, in addition to financing and legacy business income and expense items. In 2021, we included impairments of cryptocurrencies and gain or losses on sales of cryptocurrencies as part of our calculation of Adjusted EBITDA. Based upon recentSEC comments to another issuer, we have determined to exclude impairments of cryptocurrencies and gain or losses on sales of cryptocurrencies from our calculation of Adjusted EBITDA as ofDecember 31, 2021 . We will continue to evaluate the positions of FASB andSEC on the accounting treatment of cryptocurrencies.
We believe Adjusted EBITDA can be an important financial measure because it allows management, investors, and our board of directors to evaluate and compare our operating results, including our return on capital and operating efficiencies, from period-to-period by making such adjustments.
Adjusted EBITDA is provided in addition to, and should not be considered to be a substitute for, or superior to net income, the comparable measure underU.S. GAAP. Further, Adjusted EBITDA should not be considered as an alternative to revenue growth, net income, diluted earnings per share or any other performance measure derived in accordance withU.S. GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. Adjusted EBITDA has limitations as an analytical tool, and you should not consider such measures either in isolation or as substitutes for analyzing our results as reported
underU.S. GAAP. 37

Results of Operations Comparative Results for the Years Ended
Revenues: Mining revenues for the years endedDecember 31, 2020 and 2019, totaled approximately$12.0 million and$6.7 million , respectively. Other revenue consisted of license payments of approximately$0.1 million in each period. Revenues from cryptocurrency mining are impacted significantly by volatility in Bitcoin prices, as well as increases in the Bitcoin blockchain's network hash rate resulting from the growth in the overall quantity and quality of miners working to solve blocks on the Bitcoin blockchain and the difficulty index associated with the secure hashing algorithm employed in solving the blocks. 38 From early 2019 to the end of 2020 the Bitcoin blockchain's network hash rate increased by approximately 249% as a result of, among other factors, the increased number of miners working to solve blocks on the Bitcoin blockchain during that period, many of which make use of newer, more efficient ASIC chips that are specially designed to solve blocks using the SHA-256 set of cryptographic hash functions employed on the Bitcoin blockchain. For years endedDecember 31, 2020 and 2019, the average network hash rate working on the Bitcoin blockchain was 142.74 EH/s and 98.67 EH/s, respectively. Further, the difficulty index increased over 231% in the past two fiscal years. The cumulative difficulty index increase over each of years endedDecember 31, 2020 and 2019 was 43.79% and 97.67%, respectively.
Cost and Expenses:
Cost of revenue for the year endedDecember 31, 2020 of approximately$6.3 million consisted primarily of direct production costs of the mining operations, including rent and utilities and fees paid toCoinmint pursuant to theCoinmint Agreement, but excluding depreciation and amortization, which are separately stated. The cost of revenue for the year endedDecember 31, 2019 was approximately$6.1 million . The cost of revenue for the years endedDecember 31, 2020 and 2019 as a percentage of mining revenue totaled 52.2% and 90.4%, respectively. The improvement in 2020 resulted from higher average Bitcoin values for mined Bitcoin and lower fixed and variable costs incurred for costs of revenue for the second half of 2020 following the relocation to theCoinmint Facility.
During the year ended
Selling, General and Administrative Expenses:
Selling, general and administrative expenses for the year endedDecember 31, 2020 totaled approximately$10.3 million , which is an approximately$1.1 million , or a 11.9% increase, as compared to$9.2 million in the 2019 period. Compensation related expense decreased by approximately$0.6 million due primarily to staff reductions during 2019, net of severance costs and the compensation expense of$0.3 forTess Pay, Inc. ("Tess") in the 2019 period, which in 2020 is no longer reported in our consolidated financial statements. Stock-based compensation increased by approximately$2.7 million for the year endedDecember 31, 2020 as compared with the 2019 period due to the 2020 issuance of 1,544,359 restricted stock units and the accelerated vesting of 471,544 restricted stock units due to the resignation of a member of the Company's board. Legal fees decreased by approximately$0.6 million due to legal matters associated primarily with the fees for the class action and derivative suits and specialSEC related matters being higher in the 2019 period. Audit fees decreased approximately$0.3 million due to the higher level of financial activities and the audit of internal controls over financial reporting incurred for the year endedDecember 31, 2019 .
Depreciation and Amortization:
Depreciation and amortization expenses in the year endedDecember 31, 2020 totaled approximately$4.5 million , which is an increase of approximately$4.4 million , compared to$0.1 million during the year endedDecember 31, 2019 . The increase is primarily due to higher average depreciable equipment levels in the year endedDecember 31, 2020 resulting from the Company's acquisition of 7,043 new miners, which the Company depreciates over their two-year estimated usable lives using the straight-line method.
Asset Impairment Charges:
Impairment of long-term investments of$9.4 million recognized during the year endedDecember 31, 2020 was recorded in connection with the impairment of our investment in Coinsquare. The Company recorded this 100% impairment as a result of the OSC Order and Settlement Agreement in which Coinsquare and certain of its executives and directors admitted to violations ofOntario securities laws and conduct contrary to the public interest in connection with their operation of the Coinsquare Market.
Impairment charges for cryptocurrencies was
Asset impairment charges of$1.5 million were recognized during the year endedDecember 31, 2019 and were related to$0.8 million for the impairment of our cryptocurrencies accounted for as intangible assets and$0.7 million related to our intangible assets acquired in connection with our former RiotX / Logical Brokerage business. 39 Other Income and Expense:
During the year ended
During the year endedDecember 31, 2019 , we recognized losses related to the issuance of convertible notes of approximately$6.2 million and expenses totaling$6.8 million to revalue the notes and the related warrant liability to fair value.

Coinmint Co-location Mining Services Agreement
OnApril 8, 2020 , the Company entered into an agreement withCoinmint (the "Coinmint Agreement"), pursuant to whichCoinmint agreed to provide up to approximately 9.5 MW of electrical power and to perform all maintenance necessary to operate Riot's miners deployed at the Coinmint Facility. In exchange,Coinmint is reimbursed for direct production expenses and receives a performance fee based on the net cryptocurrencies generated by Riot's miners deployed at the Coinmint Facility. The amount of electrical power supplied to Riot's miners at the Coinmint Facility has subsequently been increased to accommodate Riot's expanding miner fleet. However, no formal written amendment to the Coinmint Agreement solidifying Riot's continuing access to sufficient power to operate its expanding fleet of miners has been entered into withCoinmint .

Of the remaining miners to be delivered, 48,495 new S19j-Pro model miners and 30,000 new S19XP model miners are all scheduled to be delivered throughout the year endedDecember 31, 2022 .

During the year endedDecember 31, 2020 , the Company relocated all 4,000 of these miners from its formerOklahoma facility to the Coinmint Facility inMassena, New York . 41 Revenue from Operations
Funding our operations on a go-forward basis will rely significantly on our ability to mine Bitcoin at a price above our Mining costs and revenue generated from our Hosting and Engineering customers. We expect to generate ongoing revenues from Bitcoin rewards from our Mining operations and our ability to liquidate Bitcoin rewards at future values will be evaluated from time-to-time to generate cash for operations. Generating Bitcoin rewards, for example, which exceed our production and overhead costs will determine our ability to report profit margins related to such mining operations, although accounting for our reported profitability is significantly complex. Furthermore, regardless of our ability to generate revenue from the sale of our Bitcoin from our Mining business, we may need to raise additional capital in the form of equity or debt to fund our operations and pursue our business strategy. The ability to raise funds through the sale of equity, debt financings, or the sale of Bitcoin to maintain our operations is subject to many risks and uncertainties and, even if we were successful, future equity issuances or convertible debt offerings could result in dilution to our existing stockholders and any future debt or debt securities may contain covenants that limit our operations or ability to enter into certain transactions. Our ability to realize revenue through Bitcoin production and successfully convert Bitcoin into cash or fund overhead with Bitcoin is subject to a number of risks, including regulatory, financial and business risks, many of which are beyond our control. Additionally, we have observed significant historical volatility in the market price of Bitcoin and, as such, future prices cannot be predicted. See the discussion of risks affecting our business under Part I, Item 1A. "Risk Factors" of this Annual Report.
If we are unable to generate sufficient revenue from our Mining operations, Hosting operations or Engineering operations when needed or secure additional sources of funding, it may be necessary to significantly reduce our current rate of spending or explore other strategic alternatives.
