was a Delaware corporation formed in March 2007. The Company was formed to develop, commercialize, and market a series of unique
electric generating power systems designed to produce electrical power with zero emissions or waste byproducts, based on a patented
pressure-driven expander motor and related organic rankine cycle technology.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">On April 16, 2021, 374Water Inc. (f/k/a PowerVerde, Inc.)
entered into an Agreement and Plan of Merger (the &#8220;Merger Agreement&#8221;) with 374Water, Inc., a privately held company
based in Durham, North Carolina, (&#8220;374Water&#8221;) and 374Water Acquisition Corp., a newly-formed wholly-owned
subsidiary of PowerVerde (&#8220;Sub&#8221;). The parties entered into the Agreement pursuant to their Binding Letter of Intent
dated September 20, 2020.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">Pursuant to the merger contemplated by the Merger Agreement
(the &#8220;Merger&#8221;), on April 16, 2021, Sub merged into 374Water, with 374Water as the surviving corporation. In connection
with the Merger, all 374Water shares were cancelled and 374Water, Inc. issued to the former 374Water shareholders a total of 62,410,452
shares of 374Water, Inc. common stock. Immediately following the Merger, 374Water changed its name to 374Water Systems Inc and
PowerVerde changed its name to 374Water, Inc. After the Merger, the former 374Water stockholders own 64.2% of 374Water Inc&#8217;s
issued and outstanding common stock and 53.8% of 374Water Inc.&#8217;s issued and outstanding voting stock which includes the Preferred
Stock (See Note 4). The Merger was accounted for as a reverse acquisition.</p>

to support a clean and healthy environment to sustain life. The Company plans to use cutting-edge science to recover resources
from the waste our society generates and keep  drinking water clean. The Company&#8217;s customers will include businesses and
local governments that will make the sustainable development goals a reality. No material revenues from this planned principal
operation have been generated since inception. Revenues to date have been from manufacturing assembly services and from testing,
consulting, and advisory services procedures for multiple customers, which have been performed in collaboration with Duke University.</p>

Standards Board Update No. 2014-09: &#8220;Revenue from Contracts with Customers (Topic 606).&#8221; The core principle of this
Topic is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized
in accordance with that core principle by applying the following five steps: 1) identify the contracts with a customer; 2) identify
the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance
obligations; and 5) recognize revenue when (or as) we satisfy a performance obligation.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">The Company&#8217;s performance obligations will be satisfied
at the point in time when products are shipped or delivered to the customer, which is when the customer has title and the significant
risks and rewards of ownership. Therefore, the Company&#8217;s contracts will have a single performance obligation (shipment or
delivery of product). The Company will primarily receive fixed consideration for sales of product. Manufacturing assembly services
are recognized as revenue when the assembled product is delivered to the customer and the Company has completed its performance
obligations.</p>

use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares
of stock or equity instruments (stock options and common stock purchase warrants). The fair value of each stock option award is
estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected
dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies
and other factors estimated over the expected term of the stock options. The expected term of options granted is derived using
the &#8220;simplified method&#8221; which computes expected term as the average of the sum of the vesting term plus the contract
term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected
term.</p>

Topic, ASC Topic 842 and established the core principle that a lessee should recognize the assets, representing rights-of-use,
and liabilities to make lease payments that arise from leases. For leases with a term of 12 months or less, a lessee is permitted
to make an election under which such assets and liabilities would not be recognized, and lease expense would be recognized generally
on a straight-line basis over the lease term. This ASU is effective for public entities for interim and annual reporting periods

Inc. are prepared in conformity with accounting principles generally accepted in the United States of America (&#8220;GAAP&#8221;).
The preparation of these condensed consolidated financial statements requires our management to make estimates and assumptions
about future events that effect the amounts reported in the financial statements and related notes. Future events and their effects
cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. We believe
the following critical accounting policies affect its more significant judgments and estimates used in the preparation of financial

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">The Company is a Delaware corporation formed in March 2007
by George Konrad and Fred Barker. The Company was formed in order to further develop, commercialize and market a series of unique
electric generating power systems designed to produce electrical power with zero emissions or waste byproducts, based on a patented
pressure-driven expander motor and related organic rankine cycle technology.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">In late 2017, 374Water Inc, formerly known as PowerVerde,
Inc. (&#8220;PowerVerde,&#8221; &#8220;we,&#8221; &#8220;us,&#8221; &#8220;our,&#8221; or the &#8220;Company&#8221;) was introduced
to a project funded by the Bill and Melinda Gates Foundation commonly referred to as the &#8220;Reinventing the Toilet Project&#8221;.
The foundation is focused on global sanitation improvements. One of the foundation-supported projects, ongoing for the previous
six years, involves a technology being developed at Duke University. This technology consists mainly of a chemical reaction called
supercritical water oxidation (SCWO). The concept requires a unique reactor or bioreactor that converts any organic matter such
as fecal sludge into pathogen-free water and mineral ash. This bioreactor trademarked AirSCWO, utilizing compressors and pumps,
is energy intensive. However, the reaction itself is exothermic, meaning it gives off heat during the reaction. The caloric value
(heat content) of the fecal sludge is the source of this heat release. If this heat release is captured and converted into electricity
the AirSCWO&#8217;s parasitic energy requirements may be offset or eliminated or may even result in net electricity produced. In
the latter example the bioreactor, designed for processing municipal fecal sludge and other organic waste, becomes an electrical-generating
machine producing free electricity as a byproduct.</p>

as we announced in April 2018, the Company was selected by Duke to develop the residual heat-to-power system to work in conjunction
with the bioreactor. We have begun the engineering and design process. Our selection was likely influenced by our focus on high
temperature and pressure expanders and consistent with our WSC design. We believe the SCWO application is an excellent fit for
our new product goal of providing expanders and systems capable of operating at elevated operating conditions where competition
is limited.</p>

with the Sub as the surviving corporation (the &#8220;Merger&#8221;). Upon closing of the Merger, PowerVerde would issue new shares
of PowerVerde stock to 374Water shareholders such that 374Water shareholders would own approximately 60% of the combined company,
and PowerVerde shareholders would own approximately 40%. The Merger was subject to adjustments for liabilities, and the closing
was contingent on the achievement of certain milestones and satisfaction of conditions by both parties prior to closing, including
the raising of at least $6.25 million of additional equity capital pursuant to a private placement,</p>

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;374Water, Inc., f/k/a PowerVerde, Inc. (the &#x201c;Company&#x201d;)
was a Delaware corporation formed in March 2007. The Company was formed to develop, commercialize, and market a series of unique
electric generating power systems designed to produce electrical power with zero emissions or waste byproducts, based on a patented
pressure-driven expander motor and related organic rankine cycle technology.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;On April 16, 2021, 374Water Inc. (f/k/a PowerVerde, Inc.)
entered into an Agreement and Plan of Merger (the &#x201c;Merger Agreement&#x201d;) with 374Water, Inc., a privately held company
based in Durham, North Carolina, (&#x201c;374Water&#x201d;) and 374Water Acquisition Corp., a newly-formed wholly-owned
subsidiary of PowerVerde (&#x201c;Sub&#x201d;). The parties entered into the Agreement pursuant to their Binding Letter of Intent
dated September 20, 2020.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Pursuant to the merger contemplated by the Merger Agreement
(the &#x201c;Merger&#x201d;), on April 16, 2021, Sub merged into 374Water, with 374Water as the surviving corporation. In connection
with the Merger, all 374Water shares were cancelled and 374Water, Inc. issued to the former 374Water shareholders a total of 62,410,452
shares of 374Water, Inc. common stock. Immediately following the Merger, 374Water changed its name to 374Water Systems Inc and
PowerVerde changed its name to 374Water, Inc. After the Merger, the former 374Water stockholders own 64.2% of 374Water Inc&#x2019;s
issued and outstanding common stock and 53.8% of 374Water Inc.&#x2019;s issued and outstanding voting stock which includes the Preferred
Stock (See Note 4). The Merger was accounted for as a reverse acquisition.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;With the Merger, 374Water Inc.&#x2019;s current mission is
to support a clean and healthy environment to sustain life. The Company plans to use cutting-edge science to recover resources
from the waste our society generates and keep  drinking water clean. The Company&#x2019;s customers will include businesses and
local governments that will make the sustainable development goals a reality. No material revenues from this planned principal
operation have been generated since inception. Revenues to date have been from manufacturing assembly services and from testing,
consulting, and advisory services procedures for multiple customers, which have been performed in collaboration with Duke University.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company considers all highly liquid investments purchased
with an original maturity of three months or less to be cash equivalents. The Company held no cash equivalents as of June 30, 2021,

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Accounts receivables consist of balances due from assembly
services and from service revenues. The Company monitors accounts receivable and provides allowances when considered necessary.
At June 30, 2021 and December 31, 2020, accounts receivable were considered to be fully collectible. Accordingly, no allowance
for doubtful accounts was provided.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Equipment is recorded at cost. Depreciation is computed using
the straight-line method and an estimated useful live of three years. Expenses for maintenance and repairs are charged to expense
as incurred.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Intangible assets are subject to amortization, and any impairment
is determined in accordance with ASC 360, &#x201c;Property, Plant, and Equipment.&#x201d; Intangible assets are stated at historical
cost and amortized over their estimated useful lives. The Company uses a straight-line method of amortization, unless a method
that better reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise used up can be
reliably determined.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company reviews long-lived assets for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company uses an estimate
of the undiscounted cash flows over the remaining life of its long-lived assets, or related group of assets where applicable, in
measuring whether the assets to be held and used will be realizable. Recoverability of assets held and used is measured by a comparison
of the carrying amount to the future undiscounted expected net cash flows to be generated by the asset. As of June 30, 2021, and
2020, there were &lt;span id="xdx_900_eus-gaap--ImpairmentOfLongLivedAssetsHeldForUse_pp0p0_do_c20210101__20210630_z1AvR7zp7X47" title="Impairment of long-lived assets"&gt;&lt;span id="xdx_907_eus-gaap--ImpairmentOfLongLivedAssetsHeldForUse_pp0p0_do_c20200101__20200630_zIhAt9fnLr72" title="Impairment of long-lived assets"&gt;no&lt;/span&gt;&lt;/span&gt; impairments.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company follows the revenue standards of Financial Accounting
Standards Board Update No. 2014-09: &#x201c;Revenue from Contracts with Customers (Topic 606).&#x201d; The core principle of this
Topic is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized
in accordance with that core principle by applying the following five steps: 1) identify the contracts with a customer; 2) identify
the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance
obligations; and 5) recognize revenue when (or as) we satisfy a performance obligation.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company&#x2019;s performance obligations will be satisfied
at the point in time when products are shipped or delivered to the customer, which is when the customer has title and the significant
risks and rewards of ownership. Therefore, the Company&#x2019;s contracts will have a single performance obligation (shipment or
delivery of product). The Company will primarily receive fixed consideration for sales of product. Manufacturing assembly services
are recognized as revenue when the assembled product is delivered to the customer and the Company has completed its performance
obligations.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Revenues for the six months ended June 30, 2021, and 2020
were generated from one manufacturing assembly service and from two consulting and advisory service agreements, which were recognized
when the Company completed its performance obligations under the relevant service agreements.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company has accounted for stock-based compensation under
the provisions of Accounting Standards Codification (ASC) Topic 718 &#x2013; &#x201c;Stock Compensation&#x201d; which requires the
use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares
of stock or equity instruments (stock options and common stock purchase warrants). The fair value of each stock option award is
estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected
dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies
and other factors estimated over the expected term of the stock options. The expected term of options granted is derived using
the &#x201c;simplified method&#x201d; which computes expected term as the average of the sum of the vesting term plus the contract
term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected
term.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for income taxes
using the liability method prescribed by ASC 740 - Income Taxes. Under this method, deferred tax assets and liabilities are determined
based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will
be in effect in the year in which the differences are expected to reverse. The Company records a valuation allowance to offset
deferred tax assets if, based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the
deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized as income or loss
in the period that includes the enactment date.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America requires management to make estimates and assumptions
that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those
estimates. Significant estimates in the accompanying financial statements include the fair value of equity-based compensation and
valuation allowance against deferred tax assets.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;In February 2016, the Financial Accounting Standards Board
(&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2016-02, &#x201c;Leases,&#x201d; which created a new
Topic, ASC Topic 842 and established the core principle that a lessee should recognize the assets, representing rights-of-use,
and liabilities to make lease payments that arise from leases. For leases with a term of 12 months or less, a lessee is permitted
to make an election under which such assets and liabilities would not be recognized, and lease expense would be recognized generally
on a straight-line basis over the lease term. This ASU is effective for public entities for interim and annual reporting periods
beginning after December 15, 2018, and early application is permitted. The Company adopted ASC Topic 842 on January 1, 2019 and
such adoption did not have any impact on the Company&#x2019;s financial statements.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;In August 2020, the Financial Accounting Standards Board
(&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2020-06, Debt &#x2014; Debt with Conversion and Other
Options (Subtopic 470-20) and Derivatives and Hedging &#x2014; Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40) (&#x201c;ASU
2020-06&#x201d;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require
separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope
exception guidance pertaining to equity classification of contracts in an entity&#x2019;s own equity. The new standard also introduces
additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#x2019;s own
equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective
basis, with early adoption permitted beginning on January 1, 2021.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;There are several other new accounting pronouncements issued

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company follows the revenue standards of Financial Accounting
Standards Board Update No. 2014-09: &#x201c;Revenue from Contracts with Customers (Topic 606).&#x201d; The core principle of this
Topic is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized
in accordance with that core principle by applying the following five steps: 1) identify the contracts with a customer; 2) identify
the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance
obligations; and 5) recognize revenue when (or as) we satisfy a performance obligation.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company&#x2019;s performance obligations will be satisfied
at the point in time when products are shipped or delivered to the customer, which is when the customer has title and the significant
risks and rewards of ownership. Therefore, the Company&#x2019;s contracts will have a single performance obligation (shipment or
delivery of product). The Company will primarily receive fixed consideration for sales of product. Manufacturing assembly services
are recognized as revenue when the assembled product is delivered to the customer and the Company has completed its performance
obligations.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Revenues for the six months ended June 30, 2021, and 2020
were generated from one manufacturing assembly service and from two consulting and advisory service agreements, which were recognized
when the Company completed its performance obligations under the relevant service agreements.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company has accounted for stock-based compensation under
the provisions of Accounting Standards Codification (ASC) Topic 718 &#x2013; &#x201c;Stock Compensation&#x201d; which requires the
use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares
of stock or equity instruments (stock options and common stock purchase warrants). The fair value of each stock option award is
estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected
dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies
and other factors estimated over the expected term of the stock options. The expected term of options granted is derived using

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for income taxes
using the liability method prescribed by ASC 740 - Income Taxes. Under this method, deferred tax assets and liabilities are determined
based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will
be in effect in the year in which the differences are expected to reverse. The Company records a valuation allowance to offset
deferred tax assets if, based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the
deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized as income or loss
in the period that includes the enactment date.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of America requires management to make estimates and assumptions
that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those
estimates. Significant estimates in the accompanying financial statements include the fair value of equity-based compensation and
valuation allowance against deferred tax assets.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;In February 2016, the Financial Accounting Standards Board
(&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2016-02, &#x201c;Leases,&#x201d; which created a new
Topic, ASC Topic 842 and established the core principle that a lessee should recognize the assets, representing rights-of-use,
and liabilities to make lease payments that arise from leases. For leases with a term of 12 months or less, a lessee is permitted
to make an election under which such assets and liabilities would not be recognized, and lease expense would be recognized generally
on a straight-line basis over the lease term. This ASU is effective for public entities for interim and annual reporting periods
beginning after December 15, 2018, and early application is permitted. The Company adopted ASC Topic 842 on January 1, 2019 and
such adoption did not have any impact on the Company&#x2019;s financial statements.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;In August 2020, the Financial Accounting Standards Board
(&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2020-06, Debt &#x2014; Debt with Conversion and Other
Options (Subtopic 470-20) and Derivatives and Hedging &#x2014; Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40) (&#x201c;ASU
2020-06&#x201d;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require
separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope
exception guidance pertaining to equity classification of contracts in an entity&#x2019;s own equity. The new standard also introduces
additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#x2019;s own
equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective
basis, with early adoption permitted beginning on January 1, 2021.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;There are several other new accounting pronouncements issued
or proposed by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does

financial position, operating results, or cash flows.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;As of June 30, 2021, the Company had working capital of $&lt;span id="xdx_900_ecustom--WorkingCapital_iNI_pp0p0_di_c20210630_zqLmxgBKtAuf" title="Working capital deficit"&gt;6,142,238&lt;/span&gt;

at December 31, 2020. This significant increase in working capital is due primarily to the increase in cash over the six-month
period based on the Company&#x2019;s sale and issuance of Series D Convertible Preferred Stock (see Note 4). During the second
quarter of 2021, in connection with the Merger (described in Note 4 below), the Company received gross proceeds of $&lt;span id="xdx_903_eus-gaap--ProceedsFromIssuanceOrSaleOfEquity_c20210101__20210630_zEkPfuBFoqG1" title="Proceed from sales of stock"&gt;6,551,745&lt;/span&gt;
from the sale of Series D Convertible Preferred Stock (Preferred Stock). As of June 30, 2021, the Company has an accumulated deficit
of $&lt;span id="xdx_90F_eus-gaap--RetainedEarningsAccumulatedDeficit_iNI_pp0p0_di_c20210630_z6F8uAgOVWw3" title="Accumulated deficit"&gt;1,936,266&lt;/span&gt;.
For the six months ended June 30, 2021, the Company had a net loss of $&lt;span id="xdx_90C_eus-gaap--NetIncomeLoss_iN_pp0p0_di_c20210101__20210630_zsa2eXSjEne5" title="Net loss"&gt;1,940,858&lt;/span&gt;

of net cash used in operations for the period.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company believes that the capital raises from the sale
of Preferred Stock will provide sufficient cash flow for the Company to meet its financial obligations for at least the next 12
months as they come due. These events served to mitigate the conditions that historically raised substantial doubt about the Company&#x2019;s
ability to continue as a going concern.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;In connection with the Merger, PowerVerde closed on a private
placement of 440,125 shares of Series D Convertible Preferred Stock (the &#x201c;Preferred Stock&#x201d;) with a par value of $.0001,
yielding gross proceeds of $6,551,745 (the &#x201c;Private Placement&#x201d;). The Private Placement proceeds will be used for working
capital, primarily for development, manufacture and commercialization of 374Water Inc.&#x2019;s Air SCWO Nix systems. The Preferred
Stock has a stated value of $15 per share, is convertible into common stock at $.30 per share and has voting rights based on the
underlying shares of common stock. Upon liquidation of the Company, the Preferred Stockholders have liquidation preference before
any assets can be distributed to common stockholders. The current liquidation value is $6,601,735. All of the Preferred Stock was
sold pursuant to an exemption from registration requirements under Regulation D and/or Section 4(2) of the Securities Act of 1933,
as amended.&lt;/p&gt;









&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;As a result of the Merger, the issuance of the Preferred
Stock, the former 374Water shareholders own 65.8% of 374Water Inc&#x2019;s issued and outstanding common stock and 53.8% of 374Water
Inc.&#x2019;s issued and outstanding voting stock (which includes the Preferred Stock on an as converted basis).&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Also as a result of the Merger, 374Water Inc. entered into
two-year employment agreements with 374Water founders Yaacov (Kobe) Nagar and Marc Deshusses, Ph. D. Mr. Nagar will serve as the
Company&#x2019;s CEO, replacing Richard H. Davis, who resigned upon closing of the Merger. Mr. Nagar will receive an annual salary
of $200,000. Dr. Deshusses will serve as the Company&#x2019;s Head of Technology on a part-time basis at a salary of $60,000 per
year.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;Pursuant to the Merger, Messrs. Nagar and Deshusses were

to a worldwide license agreement with Duke executed on April 16, 2021 (the &#x201c;License Agreement&#x201d;). In connection with
the License Agreement, 374Water also executed an equity transfer Agreement with Duke pursuant to which Duke received a small block
of shares of common stock (see Note 5).&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;As a result of the Merger Agreement, for financial statement
reporting purposes, the business combination between 374Water Inc. and 374Water was treated as a reverse acquisition and recapitalization
for accounting purposes with 374Water deemed the accounting acquirer and 374Water Inc. deemed the accounting acquiree under the
acquisition method of accounting in accordance with FASB Accounting Standards Codification (&#x201c;ASC&#x201d;) Section 805-10-55.&lt;/p&gt;

of $6,551,691 (the &#x201c;Private Placement&#x201d;) and settlement of a $50,000 liability for Preferred Stock shares. The Private Placement
proceeds will be used for working capital, primarily for the development, manufacturing and commercialization of 374Water&#x2019;s Air

preference before any assets can be distributed to common stockholders. The current liquidation value is $6,601,745. All of the Preferred
Stock were sold pursuant to an exemption from registration requirements under Regulation D and/or Section 4(2) of the Securities Act of

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In
April 2021, pursuant to the binding Memorandum of Understanding dated as of March 30, 2021, between 374Water and MB Holding Inc. (the
&#x201c;MOU&#x201d;), a warrant for the purchase of &lt;span id="xdx_905_ecustom--NumberOfWarrantPurchase_c20210401__20210430_zAfEoWcD8Gr7" title="Number of warrant purchase"&gt;3,783,333&lt;/span&gt; shares of common stock at an exercise price of $&lt;span id="xdx_90B_eus-gaap--WarrantExercisePriceIncrease_c20210401__20210430_zAYcrAXj8sce" title="Exercise price"&gt;.30&lt;/span&gt; per share were issued
to MB Holding Inc. as consideration for executing the MOU and was considered fully vested upon the execution of the MOU. These warrants
expire in March 2022. Those warrants were estimated to have a grant-date fair value of $0.37 per warrant or aggregate fair value of $1,399,833
which has been presented as product development expense on the condensed statements of operations.&lt;/p&gt;

&lt;p style="font: 10pt/107% Times New Roman, Times, Serif; margin: 0"&gt;During the period ended June 30, 2021, 950,000 warrants were exercised

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The fair value of those warrants granted were estimated on

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our CFO John L Hofmann is a member of
the accounting firm Kabat, Schertzer, De La Torre, Taraboulos &amp;amp; Co, LLC (&#x201c;KSDT&#x201d;). The Company paid $&lt;span id="xdx_906_eus-gaap--RelatedPartyCosts_c20210101__20210630_zsPrbA9q1Ywd" title="Related party cost"&gt;42,433&lt;/span&gt; and

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;On April 15, 2017, the Company entered into an assembly agreement
with Liberty Plugins, Inc. (&#x201c;Liberty&#x201d;) to assemble Liberty&#x2019;s Hydra electronic vehicle charging systems and ship
completed Hydras to Liberty&#x2019;s facility in Santa Barbara, California (the &#x201c;Liberty Agreement&#x201d;). Initially, Liberty
agreed to pay $1,000 for the first 10 Hydras assembled in a month, $750 per Hydra for the next 10 Hydras assembled per month and
$500 per Hydra for each Hydra assembled above 20 per month. Revenue for these products is reflected in the revenue on the Company&#x2019;s
consolidated statement of operations and amounted to $1,000 and $0 for the six months ended June 30, 2021, and 2020, respectively.
The Liberty Agreement is subject to termination by either party on 30 days&#x2019; notice.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;The Company&#x2019;s director and former CEO is a minority
shareholder and member of the Board of Directors of Liberty. Therefore, transactions with Liberty have been disclosed as transactions
with a related party.&lt;/p&gt;

oxidation (SCWO) units, which was developed principally through the efforts of Messrs. Nagar and Deshusses at the facilities of Duke
University, Durham, North Carolina (&#x201c;Duke&#x201d;), where Dr. Deshusses is a professor, is licensed to 374Water pursuant to a worldwide
license agreement with Duke executed on April 16, 2021 (the &#x201c;License Agreement&#x201d;). In connection with the License Agreement,
374Water also executed an equity transfer Agreement with Duke pursuant to which Duke received a small block of common stock in the
Company. Under the terms of the License Agreement, the Company is required to make royalty payments based on a percentage of licensed
product sales, as defined in the License Agreement which is triggered by the sale of licensed products. Further, the Company is also
required to pay royalties on a percentage of sublicensing fees. The Company will reimburse Duke for any ongoing patent expenses incurred.
During the three and six month period ending June 30, 2021, the Company has not incurred any expenses in connection with this License
Agreement. The Company may terminate the license agreement anytime by providing Duke sixty days&#x2019; notice.&lt;/p&gt;

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">374Water, Inc., f/k/a PowerVerde, Inc. (the &#8220;Company&#8221;)
was a Delaware corporation formed in March 2007. The Company was formed to develop, commercialize, and market a series of unique
electric generating power systems designed to produce electrical power with zero emissions or waste byproducts, based on a patented
pressure-driven expander motor and related organic rankine cycle technology.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">On April 16, 2021, 374Water Inc. (f/k/a PowerVerde, Inc.)
entered into an Agreement and Plan of Merger (the &#8220;Merger Agreement&#8221;) with 374Water, Inc., a privately held company
based in Durham, North Carolina, (&#8220;374Water&#8221;) and 374Water Acquisition Corp., a newly-formed wholly-owned
subsidiary of PowerVerde (&#8220;Sub&#8221;). The parties entered into the Agreement pursuant to their Binding Letter of Intent
dated September 20, 2020.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">Pursuant to the merger contemplated by the Merger Agreement
(the &#8220;Merger&#8221;), on April 16, 2021, Sub merged into 374Water, with 374Water as the surviving corporation. In connection
with the Merger, all 374Water shares were cancelled and 374Water, Inc. issued to the former 374Water shareholders a total of 62,410,452
shares of 374Water, Inc. common stock. Immediately following the Merger, 374Water changed its name to 374Water Systems Inc and
PowerVerde changed its name to 374Water, Inc. After the Merger, the former 374Water stockholders own 64.2% of 374Water Inc&#8217;s
issued and outstanding common stock and 53.8% of 374Water Inc.&#8217;s issued and outstanding voting stock which includes the Preferred
Stock (See Note 4). The Merger was accounted for as a reverse acquisition.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">With the Merger, 374Water Inc.&#8217;s current mission is
to support a clean and healthy environment to sustain life. The Company plans to use cutting-edge science to recover resources
from the waste our society generates and keep  drinking water clean. The Company&#8217;s customers will include businesses and
local governments that will make the sustainable development goals a reality. No material revenues from this planned principal
operation have been generated since inception. Revenues to date have been from manufacturing assembly services and from testing,
consulting, and advisory services procedures for multiple customers, which have been performed in collaboration with Duke University.</p>

Standards Board Update No. 2014-09: &#8220;Revenue from Contracts with Customers (Topic 606).&#8221; The core principle of this
Topic is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized
in accordance with that core principle by applying the following five steps: 1) identify the contracts with a customer; 2) identify
the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance
obligations; and 5) recognize revenue when (or as) we satisfy a performance obligation.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">The Company&#8217;s performance obligations will be satisfied
at the point in time when products are shipped or delivered to the customer, which is when the customer has title and the significant
risks and rewards of ownership. Therefore, the Company&#8217;s contracts will have a single performance obligation (shipment or
delivery of product). The Company will primarily receive fixed consideration for sales of product. Manufacturing assembly services
are recognized as revenue when the assembled product is delivered to the customer and the Company has completed its performance
obligations.</p>

the provisions of Accounting Standards Codification (ASC) Topic 718 &#8211; &#8220;Stock Compensation&#8221; which requires the
use of the fair-value based method to determine compensation for all arrangements under which employees and others receive shares
of stock or equity instruments (stock options and common stock purchase warrants). The fair value of each stock option award is
estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected
dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies
and other factors estimated over the expected term of the stock options. The expected term of options granted is derived using
the &#8220;simplified method&#8221; which computes expected term as the average of the sum of the vesting term plus the contract
term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected
term.</p>

using the liability method prescribed by ASC 740 - Income Taxes. Under this method, deferred tax assets and liabilities are determined
based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will
be in effect in the year in which the differences are expected to reverse. The Company records a valuation allowance to offset
deferred tax assets if, based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the
deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized as income or loss
in the period that includes the enactment date.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">In February 2016, the Financial Accounting Standards Board
(&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) 2016-02, &#8220;Leases,&#8221; which created a new
Topic, ASC Topic 842 and established the core principle that a lessee should recognize the assets, representing rights-of-use,
and liabilities to make lease payments that arise from leases. For leases with a term of 12 months or less, a lessee is permitted
to make an election under which such assets and liabilities would not be recognized, and lease expense would be recognized generally
on a straight-line basis over the lease term. This ASU is effective for public entities for interim and annual reporting periods
beginning after December 15, 2018, and early application is permitted. The Company adopted ASC Topic 842 on January 1, 2019 and
such adoption did not have any impact on the Company&#8217;s financial statements.</p>

Options (Subtopic 470-20) and Derivatives and Hedging &#8212; Contracts in Entity&#8217;s Own Equity (Subtopic 815-40) (&#8220;ASU
2020-06&#8221;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require
separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope
exception guidance pertaining to equity classification of contracts in an entity&#8217;s own equity. The new standard also introduces
additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#8217;s own
equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective
basis, with early adoption permitted beginning on January 1, 2021.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">As of June 30, 2021, the Company had working capital of $<span id="xdx_900_ecustom--WorkingCapital_iNI_pp0p0_di_c20210630_zqLmxgBKtAuf" title="Working capital deficit">6,142,238</span>

at December 31, 2020. This significant increase in working capital is due primarily to the increase in cash over the six-month
period based on the Company&#8217;s sale and issuance of Series D Convertible Preferred Stock (see Note 4). During the second
quarter of 2021, in connection with the Merger (described in Note 4 below), the Company received gross proceeds of $<span id="xdx_903_eus-gaap--ProceedsFromIssuanceOrSaleOfEquity_c20210101__20210630_zEkPfuBFoqG1" title="Proceed from sales of stock">6,551,745</span>
from the sale of Series D Convertible Preferred Stock (Preferred Stock). As of June 30, 2021, the Company has an accumulated deficit
of $<span id="xdx_90F_eus-gaap--RetainedEarningsAccumulatedDeficit_iNI_pp0p0_di_c20210630_z6F8uAgOVWw3" title="Accumulated deficit">1,936,266</span>.
For the six months ended June 30, 2021, the Company had a net loss of $<span id="xdx_90C_eus-gaap--NetIncomeLoss_iN_pp0p0_di_c20210101__20210630_zsa2eXSjEne5" title="Net loss">1,940,858</span>

of net cash used in operations for the period.</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">The Company believes that the capital raises from the sale
of Preferred Stock will provide sufficient cash flow for the Company to meet its financial obligations for at least the next 12
months as they come due. These events served to mitigate the conditions that historically raised substantial doubt about the Company&#8217;s
ability to continue as a going concern.</p>

any assets can be distributed to common stockholders. The current liquidation value is $6,601,735. All of the Preferred Stock was
sold pursuant to an exemption from registration requirements under Regulation D and/or Section 4(2) of the Securities Act of 1933,

oxidation (SCWO) units, which was developed principally through the efforts of Messrs. Nagar and Deshusses at the facilities of Duke
University, Durham, North Carolina (&#8220;Duke&#8221;), where Dr. Deshusses is a professor, is licensed to 374Water pursuant to a worldwide
license agreement with Duke executed on April 16, 2021 (the &#8220;License Agreement&#8221;). In connection with the License Agreement,
374Water also executed an equity transfer Agreement with Duke pursuant to which Duke received a small block of common stock in the
Company. Under the terms of the License Agreement, the Company is required to make royalty payments based on a percentage of licensed
product sales, as defined in the License Agreement which is triggered by the sale of licensed products. Further, the Company is also
required to pay royalties on a percentage of sublicensing fees. The Company will reimburse Duke for any ongoing patent expenses incurred.
During the three and six month period ending June 30, 2021, the Company has not incurred any expenses in connection with this License
Agreement. The Company may terminate the license agreement anytime by providing Duke sixty days&#8217; notice.</p>

Topic is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is recognized
in accordance with that core principle by applying the following five steps: 1) identify the contracts with a customer; 2) identify
the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance
obligations; and 5) recognize revenue when (or as) we satisfy a performance obligation.</p>

delivery of product). The Company will primarily receive fixed consideration for sales of product. Manufacturing assembly services
are recognized as revenue when the assembled product is delivered to the customer and the Company has completed its performance
obligations.</p>

of stock or equity instruments (stock options and common stock purchase warrants). The fair value of each stock option award is
estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected
dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies
and other factors estimated over the expected term of the stock options. The expected term of options granted is derived using
the &#8220;simplified method&#8221; which computes expected term as the average of the sum of the vesting term plus the contract
term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected
term.</p>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>
