ITEM 7. MANAGEMENT’S DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following Management’s
Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to help the reader understand
our results of operations and financial condition. 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 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 ended December 31, 2020, filed with the SEC on March 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, in
North 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

On May 26, 2021, we completed the acquisition of all
of the issued and outstanding equity interests in Whinstone US, Inc. (“Whinstone”) pursuant to the stock purchase agreement,
dated as of April 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 to December 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

On December 1, 2021, we entered into a membership
interest purchase agreement to acquire all of the issued and outstanding equity interests (the “ESS Metron Acquisition”) of
Ferrie 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 the SEC on December 1, 2021 under our effective Registration Statement on Form S-3 filed with the SEC on August
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

At December 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

At December 31, 2021, we had purchased, received
and/or deployed the following miners:

During 2021, we received 34,608 additional Antminer
model S19-Pro miners pursuant to purchase orders with their manufacturer, Bitmain, and, as of December 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
through December 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 the May 26, 2021 acquisition date through
December 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 of December 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.

Summary of Mining Results

The following table presents additional information
about our Mining activities, including cryptocurrency production and sales of the cryptocurrency the Company mined during the years ended
December 31, 2021, 2020 and 2019 ($ in thousands):

35

Results of Operations Comparative Results for the Years Ended
December 31, 2021 and 2020:

Revenues:

Total revenue for the years ended December 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 ended December 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 on
May 26, 2021 to December 31, 2021, Hosting revenue was $24.5 million, and there was no Hosting revenue for the year ended December 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 on December 1, 2021 to December 31, 2021, Engineering revenue was $4.2 million, and there was no Engineering revenue for the year
ended December 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 ended December
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 ended December 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 the Oklahoma City facility and, in 2021, the variable Coinmint 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 on May 26, 2021 to December 31, 2021 was $33.0 million and there were no Hosting costs for the year ended December
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 on December 1, 2021 to December 31, 2021 was $3.6 million and there were no Engineering costs for the year
ended December 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 ended December
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 ended December 31, 2020.

36

Selling, general and administrative expenses during
the years ended December 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 in August 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
ended December 31, 2021 totaled $26.3 million, which is an increase of approximately $21.8 million, as compared to $4.5 million for the
year ended December 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 to December 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 to ERCOT through its demand response programs. There were no derivative assets for the
year ended December 31, 2020.

Impairment of long-term investments of $9.4 million
recognized during the year ended December 31, 2020 was recorded in connection with the impairment of our investment in Coinsquare Ltd.,
a Canadian cryptocurrency exchange (“Coinsquare”).

Impairment of cryptocurrencies for the years ended
December 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 ended December 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 ended December 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 ended December 31, 2020.

Non-GAAP Measures

In addition to consolidated U.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 recent SEC 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 of December 31, 2021. We will continue to evaluate the positions of FASB and SEC 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 under U.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 with U.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 under U.S. GAAP.

37

Reconciliations of Adjusted EBITDA to the most comparable
U.S. GAAP financial metric for historical periods are presented in the table below:

Reconciliation of GAAP and Non-GAAP Financial Information

Results of Operations Comparative Results for the Years Ended
December 31, 2020 and 2019:

Revenues:

Mining revenues for the years ended December
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
ended December 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 ended December 31, 2020 and 2019 was 43.79% and 97.67%, respectively.

Cost and Expenses:

Cost of revenue for the year ended December
31, 2020 of approximately $6.3 million consisted primarily of direct production costs of the mining operations, including rent and utilities
and fees paid to Coinmint pursuant to the Coinmint Agreement, but excluding depreciation and amortization, which are separately stated.
The cost of revenue for the year ended December 31, 2019 was approximately $6.1 million. The cost of revenue for the years ended December
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 the Coinmint Facility.

During the year ended December 31, 2020, we
recorded a gain on the sale / exchange of cryptocurrencies of approximately $5.2 million. During the year ended December 31, 2019 the
gain on sale of cryptocurrencies was $0.7 million.

Selling, General and Administrative
Expenses:

Selling, general and administrative expenses
for the year ended December 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 for Tess 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 ended December 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 special SEC 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 ended December 31, 2019.

Depreciation and Amortization:

Depreciation and amortization expenses in the
year ended December 31, 2020 totaled approximately $4.5 million, which is an increase of approximately $4.4 million, compared to $0.1
million during the year ended December 31, 2019. The increase is primarily due to higher average depreciable equipment levels in the year
ended December 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 ended December 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 of Ontario securities laws and conduct contrary to the public interest in connection with
their operation of the Coinsquare Market.

Impairment charges for cryptocurrencies was
$1.0 million for the year ended December 31, 2020, which was recorded to recognize an impairment of our cryptocurrencies during the three
months ended March 31, 2020.

Asset impairment charges of $1.5 million were
recognized during the year ended December 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 December 31, 2020, we
recognized income of approximately $1.4 million in connection with the reversal of our registration rights penalty.

During the year ended December 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.

During the year ended December 31, 2019, we
recorded a gain of approximately $1.1 million on the deconsolidation of Tess, due to our reduced ownership interest from 50.2% to 8.8%.
No such expense was recognized during the year ended December 31, 2020.

During the years ended December 31, 2020 and 2019, interest income
and interest expense was nominal.

Other expense for the year ended December 31,
2020 was nominal. Other income was approximately $0.9 million for the year ended December 31, 2019, due to a $0.4 million gain on forgiveness
of our payable and interest in connection with our former agreement with BMSS, and a $0.5 million gain on forgiveness of various accounts
payable balances.

Income Taxes:

For the years ended December 31, 2020 and 2019,
the Company recorded income tax benefits of zero and $0.1 million, respectively.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2021, we had working capital of approximately
$463.7 million, which included cash and cash equivalents of $312.3 million. We reported a net loss of $7.9 million during the year ended
December 31, 2021. Net loss included $108.9 million in non-cash items consisting primarily of a realized gain on the sale/exchange of
long-term investment of $26.3 million and the change in fair value of our derivative asset of $12.1 million, offset by stock-based compensation
expense of $68.5 million, the impairment of cryptocurrencies of $36.5 million, depreciation and amortization of $26.3 million, an unrealized
loss on marketable securities of $13.7 million, the issuance of common stock warrants of $1.2 million and income tax expense of $0.3 million.

40

Contractual Commitments

At December 31, 2021, we had the following contractual commitments
(in thousands):

* Pursuant to the Company’s agreements
with Bitmain, the Company is responsible for all shipping charges incurred in connection with the delivery of the miners.

Coinmint Co-location Mining Services Agreement

On April 8, 2020, the Company entered into
an agreement with Coinmint (the “Coinmint Agreement”), pursuant to which Coinmint 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 with Coinmint.
The initial term of the Coinmint Agreement was six months, with automatic renewals for subsequent three month terms until terminated as
provided in the agreement.

Miners

During 2021, we
entered into six purchase agreements with Bitmain to acquire 52,500 Antminer model S19j (90 Terahash per second) (“TH/s”)
miners and 30,000 of their latest 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 through December 2022. 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 ended December 31, 2022.

During the year ended December 31, 2020, the Company
entered into purchase agreements with Bitmain for the acquisition of a total of 33,646 of their model S19, S19-Pro, and S19j-Pro Antminer
series of miners, to be shipped and delivered during 2020 and 2021. During the year ended December 31, 2020, the Company received 3,043
model S19 Antminers of these 33,646 new miners, all of which were deployed at the Coinmint Facility. The remaining 30,603 of these new
miners were delivered in monthly shipments through January 2022.

During December 2019, the Company purchased
4,000 Bitmain model S17-Pro Antminers for a total purchase price of approximately $6.3 million directly from Bitmain. During the year
ended December 31, 2020, the Company relocated all 4,000 of these miners from its former Oklahoma facility to the Coinmint Facility in
Massena, New York.

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.

At-the-Market Equity Offerings

2021
ATM Offering

In August 2021, we entered into a Sales Agreement
with Cantor Fitzgerald & Co., B. Riley FBR, Inc., BTIG, LLC, Compass Point Research & Trading, LLC and Roth Capital Partners,
LLC (the “Sales Agents”) dated August 31, 2021 (the “Sales Agreement”), pursuant to which we sold $600 million
in shares of our common stock through the Sales Agents, acting as our sales agent and/or principal, in a continuous at-the-market offering
(the “2021 ATM Offering”). All sales of the shares in connection with the ATM Offering were made pursuant to an effective
shelf registration statement on Form S-3 (Registration No. 333-259212) filed with the SEC on August 31, 2021. During the period August
31, 2021 to December 31, 2021, we received gross proceeds of $600 million ($587.2 million, net of $12.8 million in commissions paid to
the Sales Agents and expenses) from the sale of 19,910,589 shares of our common stock, with an average fair value of $29.53 per share,
in the 2021 ATM Offering. As of December 31, 2021, all $600 million in shares of our common stock registered under the December 2021 Registration
Statement had been issued and, accordingly, we completed the 2021 ATM Offering.

2020
ATM Offering

stock, with an average fair value of $19.13 per share pursuant to the registration statement on Form S-3 (File No. 333-251149) filed with
the SEC on December 4, 2020 (the “December 2020 ATM Offering”). With the sale and issuance of these shares and of the shares
previously sold and issued during the year ended December 31, 2020, all $200 million in shares of our common stock registered under the
December 2020 Registration Statement had been issued and we completed the December 2020 ATM Offering. Under the terms of the December
2020 ATM Offering, only shares of our common stock were issued.

As of October 15, 2020, the Company and H.C.
Wainwright entered into the first amendment to the Sales Agreement (the “First Amendment to the Sales Agreement”). Pursuant
to the First Amendment to the Sales Agreement, the Company sold, through H.C. Wainwright as its sales agent, $100.0 million in shares
of the Company’s common stock in an at-the-market offering (the “October 2020 ATM Offering”). The Company paid H.C.
Wainwright a commission of up to 3.0% of the aggregate gross proceeds the Company received from all sales of its common stock in the October
2020 ATM Offering.

Critical Accounting Policies

The preparation of financial statements in
conformity with generally accepted accounting principles in the United States of America (“GAAP”) requires management to make
estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future
events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise
of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to the financial statements.
The most significant accounting estimates inherent in the preparation of our financial statements include estimates associated with revenue
recognition, investments, intangible assets, stock-based compensation and business combinations.

The Company’s financial position, results
of operations and cash flows are impacted by the accounting policies the Company has adopted. In order to get a full understanding of
the Company’s financial statements, one must have a clear understanding of the accounting policies employed. A summary of the Company’s
critical accounting policies follows:

44

Fair value of financial instruments

The Company accounts for financial instruments
under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, Fair Value
Measurements (“ASC 820”). This statement defines fair value, establishes a framework for measuring fair value in generally
accepted accounting principles, and expands disclosures about fair value measurements. To increase consistency and comparability in fair
value measurements, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair
value into three levels as follows:

Level 1 — quoted prices (unadjusted)
in active markets for identical assets or liabilities;

Level 2 — observable inputs other
than Level 1, quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets and liabilities
in markets that are not active, and model-derived prices whose inputs are observable or whose significant value drivers are observable;
and

Level 3 — assets and liabilities
whose significant value drivers are unobservable.

Observable inputs are based on market data
obtained from independent sources, while unobservable inputs are based on the Company’s market assumptions. Unobservable inputs
require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may fall into different
levels of the fair value hierarchy. In those instances, the fair value measurement is required to be classified using the lowest level
of input that is significant to the fair value measurement. Such determination requires significant management judgment. As of December
31, 2021, the Company had derivative assets and contingent consideration liability measured at fair value. As of December 31, 2020, there
were no financial assets or liabilities measured at fair value. The carrying amounts of the Company’s financial assets and liabilities,
such as cash and cash equivalents, and accounts payable, approximate fair value due to the short-term nature of these instruments.

Cryptocurrencies

Cryptocurrencies (primarily Bitcoin) are included
in current assets in the accompanying consolidated balance sheets. The classification of cryptocurrencies as a current asset has been
made after the Company’s consideration of the significant consistent daily trading volume on readily available cryptocurrency exchanges,
there are no limitations or restrictions on Company’s ability to sell Bitcoin and the pattern of actual sales of Bitcoin by the
Company. Cryptocurrencies purchased are recorded at cost and cryptocurrencies awarded to the Company through its mining activities are
accounted for in connection with the Company’s revenue recognition policy disclosed below.

Cryptocurrencies held are accounted for as
intangible assets with indefinite useful lives. An intangible asset with an indefinite useful life is not amortized but assessed for impairment
annually, or more frequently, when events or changes in circumstances occur indicating that it is more likely than not that the indefinite-lived
asset is impaired. Impairment exists when the carrying amount exceeds its fair value, which is measured using the quoted price of the
cryptocurrency at the time its fair value is being measured. In testing for impairment, the Company has the option to first perform a
qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more
likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is
required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost
basis of the asset. Subsequent reversal of impairment losses is not permitted.

Purchases of cryptocurrencies by the Company
are included within investing activities in the accompanying consolidated statements of cash flows, while cryptocurrencies awarded to
the Company through its mining activities are included within operating activities on the accompanying consolidated statements of cash
flows. The sales of cryptocurrencies are included within investing activities in the accompanying consolidated statements of cash flows
and any realized gains or losses from such sales are included in other income (expense) in the consolidated statements of operations.
The Company accounts for its gains or losses in accordance with the first in first out (FIFO) method of accounting.

Investment in marketable equity securities

Our investment in marketable equity securities
consists entirely of common shares of Mogo, Inc. (NASDAQ: MOGO), resulting from the April and May 2021 transactions. (See Note 7, “Investments
in Marketable Equity Securities”). The Company accounted for this investment in accordance with ASC 321, Investments-Equity Securities,
(“ASC 321”) due to the shares having a readily determinable fair value since they are traded on NASDAQ and have significant
average daily volume traded. As a result, the investment is required to be measured at fair value at each balance sheet date with unrealized
holding gains and losses recorded in other income (expense).

45

Impairment of long-lived assets

Management reviews long-lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets
to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated
by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceeds the fair value of the assets.

Leases

Effective January 1, 2019, the Company accounts
for its leases under ASC 842, Leases (“ASC 842”). Under this guidance, arrangements meeting the definition of a lease
are classified as operating or financing leases, and are recorded on the consolidated balance sheet as both a right of use asset and lease
liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s
incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset
is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right of use asset
result in straight-line rent expense over the lease term.

As of December 31, 2021, the Company leases
its primary office locations, which expire between 2.5 and seven years, manufacturing facilities of ESS Metron, which expire between 3.5
and 10 years and a ground lease at the Whinstone Facility that expires in December 2030, all of which are inclusive of extension options
the Company is reasonably certain will be exercised. At December 31, 2020, the Company did not have any significant operating lease balances.

In November 2021, the Company entered into
a lease termination agreement with the landlord of certain Whinstone abandoned leases for approximately $0.9 million. After eliminating
the associated operating lease liabilities, we recognized other income of approximately $0.7 million during the year ended December 31,
2021.

The Company also terminated two former operating
leases during the year ended December 31, 2020: (i) the lease of the Oklahoma facility and (ii) the Florida lease, both of which are discussed
under “Prior Leases” above.

In calculating the right of use asset and lease
liability, the Company elects to combine lease and non-lease components as permitted under ASC 842. The Company excludes short-term leases
having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line
basis over the lease term.

Revenue Recognition

Mining

The Company recognizes revenue under ASC 606,
Revenue from Contracts with Customers. The core principle of the revenue standard is that a company should recognize revenue to depict
the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be
entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:

·  Step
1: Identify the contract with the customer;

·  Step
2: Identify the performance obligations in the contract;

·  Step
3: Determine the transaction price;

·  Step
4: Allocate the transaction price to the performance obligations in the contract; and

·  Step
5: Recognize revenue when the Company satisfies a performance obligation.

In order to identify the performance obligations
in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or
service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle
of goods or services) if both of the following criteria are met: The customer can benefit from the good or service either on its own or
together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and
the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract
(i.e., the promise to transfer the good or service is distinct within the context of the contract).

46

If a good or service is not distinct, the good
or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

The transaction price is the amount of consideration
to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised
in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity
must consider the effects of all of the following:

Variable consideration is included in the transaction
price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur
when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance
obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized
when that performance obligation is satisfied, at a point in time or over time as appropriate.

The Company has entered into digital asset
mining pools by executing contracts, as amended from time to time, with the mining pool operators to provide computing power to the mining
pool. The contracts are terminable at any time by either party and the Company’s enforceable right to compensation only begins when
the Company provides computing power to the mining pool operator. In exchange for providing computing power, the Company is entitled to
a fractional share of the fixed cryptocurrency award the mining pool operator receives (less digital asset transaction fees to the mining
pool operator which are immaterial and are recorded as a deduction from revenue), for successfully adding a block to the blockchain. The
terms of the agreement provide that neither party can dispute settlement terms after thirty-five days following settlement. The Company’s
fractional share is based on the proportion of computing power the Company contributed to the mining pool operator to the total computing
power contributed by all mining pool participants in solving the current algorithm.

Providing computing power to solve complex
cryptographic algorithms in support of the Bitcoin blockchain (in a process known as “solving a block”) is an output of the
Company’s ordinary activities. The provision of providing such computing power is the only performance obligation in the Company’s
contracts with mining pool operators. The transaction consideration the Company receives, if any, is noncash consideration, which the
Company measures at fair value on the date received, which is not materially different than the fair value at contract inception or the
time the Company has earned the award from the pools. The consideration is all variable. Because it is not probable that a significant
reversal of cumulative revenue will not occur, the consideration is constrained until the mining pool operator successfully places a block
(by being the first to solve an algorithm) and the Company receives confirmation of the consideration it will receive, at which time revenue
is recognized. There is no significant financing component in these transactions.

Fair value of the cryptocurrency award received
is determined using the market rate of the related cryptocurrency at the time of receipt.

47

Hosting

In general, we provide power for our data center
customers on a variable (sub-metered) basis. A customer pays us variable monthly fees for the specific amount of power utilized at rates
specified in each contract, subject to certain minimums. We recognize variable power revenue each month as the uncertainty related to
the consideration is resolved, power is provided to our customers, and our customers utilize the power (the customer simultaneously receives
and consumes the benefits of the Company’s performance).

We have determined that our contracts contain
a series of performance obligations which qualify to be recognized under a practical expedient available known as the “right to
invoice.” This determination allows variable consideration in such contracts to be allocated to and recognized in the period to
which the consideration relates, which is typically the period in which it is billed, rather than requiring estimation of variable consideration
at the inception of the contract. We have also determined that the contracts contain a significant financing component because the timing
of revenue recognition differs from the timing of invoicing by a period, exceeding one year.

The Company also installs certain hosted customers’
mining equipment and bills the customer at a fixed fee per piece of equipment or at an hourly rate. Revenue is recognized upon completion
of the installation.

We generate engineering and construction services
revenue from the fabrication and deployment of immersion cooling technology for Bitcoin mining customers. We bill the customer at a fixed
monthly fee or at an hourly rate. For the construction of customer-owned equipment, revenue is recognized upon completion of each phase
of the construction project, as defined in each contract. For construction of assets owned by Whinstone but paid for and used by the customer
during the term of their hosting contract, revenue is recognized on a straight-line basis over the remaining life of the contract.

Maintenance services include cleaning, cabling
and other services to maintain the customers’ equipment. We bill the customer at a fixed monthly fee or at an hourly rate. Revenue
is recognized as these services are provided.

Deferred revenue is primarily from advance
payments received and is recognized on a straight-line basis over the remaining life of the contract or upon completion of the installation
of the customers’ equipment.

Our primary hosting contracts contain Service
Level Agreement clauses, which guarantee a certain percentage of time the power will be available to our customer. In the rare case that
we may incur penalties under these clauses, we account for payments made to customers in accordance with ASC 606-10-32-25, Consideration
Payable to a Customer, which requires the payment be recognized as variable consideration and a reduction of the transaction price
and, therefore, of revenue, when not in exchange for a good or service from the customer.

Engineering

Substantially all revenue is derived from the
sale of custom products built to customers’ specifications under fixed-price contracts with one identified performance obligation.
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.

To determine the amount of revenue to recognize
over time, the Company utilizes the cost-to-cost method as management believes cost incurred best represents the amount of work completed
and remaining on projects. As the cost-to-cost method is driven by incurred cost, the Company calculates the percentage of completion
by dividing costs incurred to date by the total estimated cost. The percentage of completion is then multiplied by estimated revenues
to determine inception-to-date revenue. Approved changes to design plans are generally recognized as an adjustment to the percentage of
completion calculation on a catch-up basis. Revenue recognized for the period is the current inception-to-date recognized revenue less
the prior period inception-to-date recognized revenue. If a contract is projected to result in a loss, the entire contract loss is recognized
in the period when the loss was first determined, and the amount of the loss is updated in subsequent reporting periods. Additionally,
contract costs incurred to date and expected total contract costs are continuously monitored during the term of the contract.

48

Changes in the job performance, job conditions
and final contract settlements are factors that influence management’s assessment of total contract value and the total estimated
costs to complete those contracts, and therefore, profit and revenue recognition. Any costs to obtain a contract are not material to the
Company’s financial statements and would be expensed as incurred. Because of the inherent uncertainties in estimating costs, it
is at least reasonably possible that the estimates used will change within the near term. The length of time for the Company to complete
a custom product varies but is typically between four to 12 weeks.

Customers are typically required to make periodic
progress payments to the Company based on contractually agreed-upon milestones. Invoices are due net, 30 days, and retainage, if any,
is generally due 30 days after delivery. Taxes collected from customers and remitted to governmental authorities are excluded from revenue.
Shipping and handling costs are treated as fulfillment costs and are included in cost of sales.

Other Revenue

Other revenue is revenue recognized from an
upfront license fee generated from our legacy animal health business. The upfront fee was recorded as deferred revenue and is being amortized
into revenue over the term of the License Agreement.

Derivative Accounting

Power Supply Contract and Demand Response Services

In May 2020, Whinstone entered into a Power
Supply Agreement with TXU Energy Retail Company LLC (“TXU”) to provide the delivery of a fixed amount of electricity by TXU
to Whinstone (via the facility owned by Oncor Electric Delivery Company, LLC (“Oncor”)) for a fixed price through April 30,
2030. The Power Supply Agreement provides a consistent and sufficient supply of electricity at the Whinstone Facility. If Whinstone uses
more electricity than contracted, the cost of the excess is incurred at the current spot rate. Concurrently, Whinstone entered into a
contract with Oncor for the extension of delivery system transmission/substation facilities to facilitate delivery of the electricity
to the Whinstone Facility (the “Facilities Agreement”). Power costs incurred under this contract are determined on an hourly
basis using settlement information provided by the Electric Reliability Council of Texas (“ERCOT”) and are recorded in cost
of revenues - data center hosting in our consolidated statements of operations.

The demand response services program (“Demand
Response Service”) provides the ERCOT market with valuable reliability and economic services by helping to preserve system reliability,
enhancing competition, mitigating price spikes, and encouraging the demand side of the market to respond better to wholesale price signals.
In collaboration with market participants such as the Company, ERCOT has developed demand response products and services for customers
that have the ability to reduce or modify electricity use in response to instructions or signals. Market participants with electrical
loads like Whinstone may participate in the Demand Response Service program directly by offering their electrical loads into the ERCOT
markets, or indirectly by voluntarily reducing their energy usage in response to increasing wholesale prices.

While we manage operating costs at the Whinstone
Facility in part by periodically selling unused or uneconomical power in the market back to ERCOT, we do not consider such actions trading
activities. That is, we do not engage in speculation in the power market as part of our ordinary activities. Because the Demand Response
Services programs allow for net settlement, we have determined the Power Supply Agreement meets the definition of a derivative under ASC
815, Derivatives and Hedging, (“ASC 815”). However, because we have the ability to sell the power back to the grid
rather than take physical delivery, physical delivery is not probable through the entirety of the contract and therefore, we do not believe
the normal purchases and normal sales scope exception applies to the Power Supply Agreement. Accordingly, the Power Supply Agreement (the
non-hedging derivative contract) is recorded at estimated fair value each reporting period with the change in the fair value recorded
in change in fair value of derivative asset in the consolidated statements of operations.

In February 2021, the State of Texas experienced
an extreme and unprecedented winter weather event that resulted in prolonged freezing temperatures and caused an electricity generation
shortage that was severely disruptive to the whole state. While demand for electricity reached extraordinary levels due to the extreme
cold, the supply of electricity significantly decreased in part because of the inability of certain power generation facilities to supply
electric power to the grid. Due to the extreme market price of electricity during this time, at the request of ERCOT, Whinstone stopped
supplying power to its customers and instead sold power back to the grid.

49

In April 2021, under the provisions of the
TXU Power Supply Agreement, and as a result of the weather event, Whinstone entered into a Qualified Scheduling Entity (“QSE”)
Letter Agreement, which resulted in Whinstone being entitled to receive approximately $125.1 million for its power sales during the February
winter storm, all under the terms and conditions of the QSE Letter Agreement. Whinstone received cash of $29.0 million in April 2021 (after
deducting $10.0 million in power management fees owed by Whinstone), approximately $59.7 million is scheduled to be credited against future
power bills of Whinstone beginning in 2022 and the remaining $26.3 million is contingent upon ERCOT’s future remittance. These amounts
are gross before fair value adjustments and expenses incurred by Whinstone for power management fees noted above and customer settlements.
The fair value of the settlement agreement was estimated and recognized as an asset as part of acquisition accounting. Additionally, pursuant
to the Northern Data stock purchase agreement, the Company agreed to pay Seller additional consideration in cash in the amount of the
future power credits, net of income taxes, when and if realized by Whinstone. See Note 4, “Acquisitions”.

Business Combinations

The Company applies the provisions of ASC Topic
805, Business Combinations, (“ASC 805”) in the accounting for acquisitions of businesses. ASC 805 requires us to use
the acquisition method of accounting by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed,
and any non-controlling interest in the acquired business, measured at their acquisition date fair values. Goodwill as of the acquisition
date is measured as the excess of consideration transferred over the aforementioned amounts. Contingent consideration is included within
the purchase price and is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is
remeasured to fair value as of each reporting date until the contingency is resolved, and subsequent changes in fair value are recognized
in earnings. Contingent consideration is recorded in long-term liabilities in our consolidated balance sheets.

While we use our best estimates and assumptions
to accurately apply preliminary values to assets acquired and liabilities assumed at the acquisition date as well as contingent consideration,
where applicable, these estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which
may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding
offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of the assets acquired or liabilities
assumed, whichever comes first, any subsequent adjustments are recorded in our consolidated statements of operations.

Accounting for business combinations requires
management to make significant estimates and assumptions, especially at the acquisition date, including estimates for intangible assets,
contractual obligations assumed, pre-acquisition contingencies, and contingent consideration, where applicable. Although we believe the
assumptions and estimates we have made have been reasonable and appropriate, they are based in part on historical experience and information
obtained from management of the acquired companies and are inherently uncertain. Critical estimates in valuing certain of the intangible
assets we have acquired include; future expected cash flows from customer contracts, discount rates, and estimated market changes in the
value of the Power Supply Agreement, which is accounted for as a nonhedged derivative contract. Unanticipated events and circumstances
may occur that may affect the accuracy or validity of such assumptions, estimates, or actual results.

Acquisition-related expenses are recognized separately from the
business combination and are expensed as incurred.

Goodwill and Other Intangible Assets

Goodwill represents the cost of a business
acquisition in excess of the fair value of the net assets acquired. The Company determined that it has three reporting units for goodwill
impairment testing purposes, Bitcoin Mining, Data Center Hosting, and Electrical Products and Engineering, which is consistent with internal
management reporting and management’s oversight of operations. Goodwill is not amortized and is reviewed for impairment annually
as of December 31 or more frequently if facts and circumstances indicate that it is more likely than not that the fair value of a reporting
unit is less than its carrying amount, including goodwill. We use both qualitative and quantitative analyses in making this determination.
Our analyses require significant assumptions and judgments, including assumptions about future economic conditions, revenue growth, and
operating margins, among other factors. Example events or changes in circumstances considered in the qualitative analysis, many of which
are subjective in nature, include: a significant negative trend in our industry or overall economic trends, a significant change in how
we use the acquired assets, a significant change in or our business strategy, a significant decrease in the market value of the asset,
a significant change in regulations or in the industry that could affect the value of the asset, and a change in segments. If it is more
likely than not that the fair value of a reporting unit is less than its carrying amount, the Company performs the quantitative test to
identify and measure the amount of goodwill impairment loss. The Company compares the fair value of the reporting unit with its carrying
amount. If the carrying amount exceeds the fair value, goodwill of the reporting unit is considered impaired and that excess is recognized
as a goodwill impairment loss.

Intangible assets with finite lives are comprised
of customer contracts that are amortized on a straight-line basis over their expected useful lives, which is their contractual term. The
Company performs assessments to determine whether finite-lived classification is still appropriate at least annually. The carrying value
of finite-lived assets and their remaining useful lives are also reviewed at least annually to determine if circumstances exist which
may indicate a potential impairment or revision to the amortization period. A finite-lived intangible asset is considered to be impaired
if its carrying value exceeds the estimated future undiscounted cash flows to be derived from it. We exercise judgment in selecting the
assumptions used in the estimated future undiscounted cash flows analysis. Impairment is measured by the amount that the carrying value
exceeds fair value.

Segment and Reporting Unit Information

Operating segments are defined as components
of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”)
in deciding how to allocate resources to an individual segment and in assessing performance. A committee consisting of the Company’s
executives is determined to be the CODM. The Company has three operating segments as of December 31, 2021. See Note 18, “Segment
Information”.

Stock Based Compensation

The Company accounts for share-based payment
awards exchanged for services at the estimated grant date fair value of the award. Stock options issued under the Company’s equity
incentive plans are granted with an exercise price equal to no less than the market price of the Company’s stock at the date of
grant and expire up to ten years from the date of grant. These options generally vest on the grant date or over a one- year period.

The Company estimates the fair value of stock
option grants using the Black-Scholes option pricing model and the assumptions used in calculating the fair value of stock-based awards
represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment.

Expected Term - The expected term of
options represents the period that the Company’s stock-based awards are expected to be outstanding based on the simplified method,
which is the half-life from vesting to the end of its contractual term.

Expected Volatility - The Company computes
stock price volatility over expected terms based on its historical common stock trading prices.

Risk-Free Interest Rate - The Company
bases the risk-free interest rate on the implied yield available on U. S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend - The Company has
never declared or paid any cash dividends on its common shares and does not plan to pay cash dividends in the foreseeable future, and,
therefore, uses an expected dividend yield of zero in its valuation models.

The Company elected to account for forfeited
awards as they occur, as permitted by Accounting Standards Update (“ASU”) 2016-09. Ultimately, the actual expenses recognized
over the vesting period will be for those shares that vested.

Earnings (loss) per share

Basic net earnings (loss) per share (“EPS”)
of common stock is computed by dividing the Company’s net earnings (loss) by the weighted average number of shares of common stock
outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue
common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings
of the entity. The Company excludes the unvested restricted share units (RSUs) awarded to its employees, officers, directors, and contractors
under the 2019 Equity Plan from this net loss per share calculation because including them would be antidilutive.

Recently issued and adopted accounting pronouncements

The Company continually assesses any new accounting
pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s
financial reporting, the Company undertakes a review to determine the consequences of the change to its financial statements and believes
that there are proper controls in place to ascertain that the Company’s financial statements properly reflect the change.

We have considered recently issued accounting
pronouncements and do not believe the adoption of such pronouncements will have a material impact on our consolidated financial statements.

See Note 3 to our financial statements beginning
on page F-9 of this Form 10-K for a description of recent accounting pronouncements applicable to our financial statements.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.
