Power Technologies, Inc. (the &#x201c;Company&#x201d; or &#x201c;OPT&#x201d;) was founded in 1984 in New Jersey, commenced business operations
in 1994 and re-incorporated in Delaware in 2007. The Company provides ocean data collection and reporting, marine power, offshore communications
and Maritime Domain Awareness Systems (&#x201c;MDA&#x201d; or &#x201c;MDAS&#x201d;) products and integrated solutions. The Company&#x2019;s
solutions focus on three major service areas: Data as a Service (&#x201c;DaaS&#x201d;), which includes data collected by Wave Adaptive
Modular Vessel (WAM-V&#xae;) autonomous vehicles and PowerBuoy&#xae; product lines; Robotics as a Service (&#x201c;RaaS&#x201d;), which provides
a lower cost subscription model for customers to access use of WAM-V&#x2019;s&#xae;; and Power as a Service (&#x201c;PaaS&#x201d;), which
includes PowerBuoy&#xae; products. The Company offers products and services to a wide-range of customers, including those in government
and offshore energy, oil and gas, construction, wind power and other industries. The Company has been involved in the entire life cycle
of product development, from product design through assembly, testing, deployment, maintenance and upgrades, while working closely with
partners across the supply chain. The Company&#x2019;s solutions are based on technologies that enable autonomous, zero or low carbon
emitting, and cost-effective data collection, analysis, transportation, cooperation with other assets such as aerial drones, and communication.
The Company&#x2019;s solutions are primarily suited to ocean and other offshore environments, and support generation of actionable intelligence
on a standalone basis or working with other data sources. The Company then channels the information it collects, and other communications,
through control equipment linked to edge computing and cloud hosting environments. The Company&#x2019;s goal is to generate most revenue
from the sale or lease of products and solutions. The Company expects to continue having net cash outflows until it can generate positive
cash flow from the commercialization of products and services.&lt;/span&gt;&lt;/p&gt;

Commission (&#x201c;SEC&#x201d;), instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information
and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal
recurring adjustments) considered necessary for a fair presentation have been included. The interim operating results are not necessarily
indicative of the results for a full year or for any other interim period. Further information on potential factors that could affect
the Company&#x2019;s financial results can be found in the Company&#x2019;s Annual Report on Form 10-K for the year ended April 30, 2024,
as filed with the SEC and elsewhere in subsequent Exchange Act filings, including this Form 10-Q. Certain amounts have been reclassified
to conform to current period presentation. This reclassification had no impact on the previously reported net loss or comprehensive loss.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;For
the nine months ended January 31, 2025, the Company incurred net losses of approximately $&lt;span id="xdx_900_eus-gaap--NetIncomeLoss_iN_pn5n6_di_c20240501__20250131_zVMod15HB178" title="Net loss"&gt;15.1&lt;/span&gt; million and used cash in operations of

In addition, the Company has continued to make investments to support order backlog and future growth. For
the nine months ended January 31, 2025 and through the date of filing of this Form 10-Q, the Company has obtained additional capital
financing through our capital raises with certain investors. Despite this, management believes the Company&#x2019;s current cash, cash
equivalents, and restricted cash balances at January 31, 2025 of $&lt;span id="xdx_90A_eus-gaap--CashCashEquivalentsRestrictedCashAndRestrictedCashEquivalents_iI_pn5n6_c20250131_zgcXCslowVgg" title="Current cash, cash equivalents, and restricted cash"&gt;10.2&lt;/span&gt; million may not be sufficient to fund its planned expenditures

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s future results of operations involve significant risks and uncertainties. Factors that could affect the Company&#x2019;s
future operating results and could cause actual results to vary materially from expectations include, but are not limited to, performance
of its products, its ability to market and commercialize its products and new products that it may develop, access to capital, technology
development, scalability of technology and production, ability to attract and retain key personnel, concentration of customers and suppliers,
pending or threatened litigation, and deployment risks and integration of acquisitions.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;These
conditions raise substantial doubt about the Company&#x2019;s ability to continue as a going concern. The ability to continue as a going
concern is dependent upon the Company&#x2019;s operations in the future and/or obtaining the necessary financing to meet its obligations
and repay its liabilities arising from normal business operations when they become due. The accompanying consolidated financial statements
have been prepared on a basis which assumes the Company is a going concern and do not include any adjustments to reflect the possible
future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from
any uncertainty related to the Company&#x2019;s ability to continue as a going concern. Such adjustments could be material.&lt;/span&gt;&lt;/p&gt;

preparation of the consolidated financial statements requires management of the Company to make several estimates and assumptions relating
to the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue
and expenses during the period. Significant items subject to such estimates and assumptions include, among other items, stock-based compensation
based on actual and projected revenues, over time revenue recognition, valuation consideration related to business combinations, including
contingent consideration based on actual and projected revenues, including discount rates and present values, and other assumptions and
estimates used to evaluate the recoverability of long-lived assets, goodwill and other intangible assets. Actual results could differ
from those estimates.&lt;/span&gt;&lt;/p&gt;

receivable are stated at the net amount expected to be collected. Amounts are usually due between 30 and 90 days after the invoice issuance.
The Company is exposed to credit losses primarily on accounts receivable and contract assets related to sales to customers. If applicable,
an allowance for credit losses is established to provide for the expected lifetime credit losses by evaluating factors such as customer
creditworthiness, historical payment and loss experiences, current economic conditions (including geographic and political risk), and
the age and status of outstanding receivables. Based on these factors, management has determined the allowance for credit losses of approximately
$&lt;span id="xdx_90E_eus-gaap--AllowanceForDoubtfulAccountsReceivableCurrent_iI_c20250131_zkSFicU5KQJb" title="Allowance for credit losses"&gt;100,000&lt;/span&gt;. Expected credit losses are written off in the period in which the financial assets are no longer collectible.&lt;/span&gt;&lt;/p&gt;

Company grants credit to its customers, generally, without collateral, under normal payment. Generally, invoicing occurs after the services
are performed or control of the product has transferred to the customer. Accounts receivable represent an unconditional right to consideration
arising from the Company&#x2019;s performance under contracts with customers.&lt;/span&gt;&lt;/p&gt;

and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is calculated using the
straight-line method over the estimated useful lives (three to ten years) of the assets. Leasehold improvements are amortized using the
straight-line method over the shorter of the estimated useful life of the asset or the remaining lease term. Expenses for maintenance
and repairs are charged to operations as incurred. Property and equipment is also reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows expected to be generated
by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, then an impairment charge is recognized in
the amount by which the carrying amount of the asset exceeds the fair value of the asset.&lt;/span&gt;&lt;/p&gt;

Company accounts for revenue in accordance with Accounting Standards Codification 606 (ASC 606) for contracts with customers and Accounting
Standards Codification 842 (ASC 842) for leasing arrangements. In relation to ASC 606, which states that a performance obligation is
the unit of account for revenue recognition, the Company assesses the goods or services promised in a contract with a customer and identifies
as a performance obligation as either: a) a good or service (or a bundle of goods or services) that is distinct; or b) a series of distinct
goods or services that are substantially the same and that have the same pattern of transfer to the customer. A contract may contain
a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the Company
allocates the contracted transaction price to each performance obligation based upon the relative standalone selling price, which represents
the price the Company would sell a promised good or service separately to a customer. The Company determines the standalone selling price
based upon the facts and circumstances of each obligated good or service. When no observable standalone selling price is available, the
standalone selling price is generally estimated based upon the Company&#x2019;s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
nature of the Company&#x2019;s contracts may give rise to several types of variable consideration, including unpriced change orders, liquidated
damages and penalties. Variable consideration can also arise from modifications to the scope of services. Variable consideration is included
in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once
the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether
to include such amounts in the transaction price are based largely on the assessment of legal enforceability, performance, and any other
information (historical, current, and forecasted) that is reasonably available to us. There was no variable consideration as of January
31, 2025 or 2024. The Company presents shipping and handling costs, that occur after control of the promised goods or services transfer
to the customer, as fulfilment costs in costs of revenues and regular shipping and handling activities charged to operating expenses.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Company recognizes revenue when or as it satisfies a performance obligation by transferring a good or service to a customer, either (1)
at a point in time or (2) over time. A good or service is transferred when or as the customer obtains control. The evaluation of whether
control of each performance obligation is transferred at a point in time or over time is made at contract inception. Input measures such
as costs incurred are utilized to assess progress against specific contractual performance obligations for the Company&#x2019;s services.
The selection of the method to measure progress towards completion requires judgment and is based on the nature of the services to be
provided. For the Company, the input method using costs or labor hours incurred best represents the measure of progress against the performance
obligations incorporated within the contractual agreements. If estimated total costs on any contract project a loss, the Company charges
the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated
costs to complete contracts, including penalties, change orders, claims, anticipated losses, and others are recorded in the accounting
period in which the events indicating a loss are known and the loss can be reasonably estimated. These loss projections are re-assessed
for each subsequent reporting period until the project is complete. Such revisions could occur at any time and the effects may be material.

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s contracts are either cost-plus contracts, fixed-price contracts, time and material agreements, lease or service agreements.
Under cost plus contracts, customers are billed for actual expenses incurred plus an agreed-upon fee.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company has two types of fixed-price contracts, firm fixed-price and cost-sharing. Under firm fixed-price contracts, the Company receives
an agreed-upon amount for providing products and services specified in the contract, and a profit or loss is recognized depending on
whether actual costs are more or less than the agreed-upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the
customer is only intended to fund a portion of the costs on a specific project. Under cost-sharing contracts, an amount corresponding
to the revenue is recorded in cost of revenue, resulting in gross profit on these contracts of zero. The Company reports its disaggregation
of revenue by contract type since this method best represents the Company&#x2019;s business. For the nine-month periods ended January
31, 2025 and 2024, the majority of the Company&#x2019;s contracts were classified as firm fixed-price and the remainder were cost-sharing.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection
with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company&#x2019;s
accounts receivable balance is made up entirely of customer contract-related balances.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s revenue also includes revenue from certain contracts which do not fall within the scope of ASC 606, but under the scope
of ASC 842, &#x201c;Leases&#x201d;. At inception of a contract for those classified under ASC 842, the Company classifies leases as either
operating or financing in accordance with the authoritative accounting guidance contained within ASC 842. If the direct financing or
sales-type classification criteria are met, then the lease is accounted for as a finance lease. All others are treated as operating leases.
The Company recognizes revenue from operating lease arrangements generally on a straight-line basis over the lease term, or as agreed
upon in-use days are utilized, which is presented in Revenues in the Consolidated Statement of Operations. The Company also enters into
lease arrangements for its PowerBuoys&#xae; and Wave Adaptive Modular Vessels (&#x201c;WAM-V&#xae;&#x201d;) with certain customers. Revenue
related to multiple-element arrangements is allocated to lease and non-lease elements based on their relative standalone selling prices
or expected cost plus a margin approach. Lease elements generally include a PowerBuoy&#xae;, WAM-V&#xae;, and components, while non-lease
elements, which the Company expects to become more prevalent, generally include engineering, monitoring and support services. In the
lease arrangement, the customer may be provided with an option to extend the lease term or purchase the leased buoy or WAM-V&#xae; at
some point during and/or at the end of the lease term.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined that collectability
of any portion of the contract value is not probable, an analysis of variable consideration will be performed using either the most likely
amount or expected value method to determine the amount of revenue that must be constrained until the scenario causing the variability
has been resolved.&lt;/span&gt;&lt;/p&gt;

is assessed for impairment using a qualitative or quantitative approach. The Company performs an annual impairment test of goodwill and
further periodic tests to the extent indicators of impairment develop between annual impairment tests. There were no indications of potential
impairment of goodwill identified for the nine months ended January 31, 2025 and 2024. Where the Company uses a qualitative analysis,
it considers factors that include historical financial performance, macroeconomic and industry conditions, and the legal and regulatory
environment. If the qualitative assessment indicates that it is more likely than not that an impairment exists, then a quantitative assessment
is also performed. The quantitative assessment requires an analysis of several estimates including future cash flows or income consistent
with management&#x2019;s strategic business plans, annual revenue growth rates and the selection of assumptions underlying a discount
rate (weighted average cost of capital) based on market data available at the time to determine the fair value of the Company. If the
fair value is less than the carrying amounts, an impairment charge for the difference is recorded. The Company acquired goodwill as part
of its purchase of MAR. Management performed its annual qualitative assessment in fiscal year 2024 and determined that it is more likely
than not that no goodwill impairment existed as of April 30, 2024.&lt;/span&gt;&lt;/p&gt;

attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective
tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary differences and operating loss and tax credit carry forwards
are expected to be recovered, settled or utilized. In assessing the realizability of deferred tax assets, management considers whether
it is more likely than not that some portion or all the deferred tax assets will not be realized. If such event occurs, a valuation allowance
is recorded. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes
the enactment date.&lt;/span&gt;&lt;/p&gt;

December 2023, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued ASU 2023-09, which improves the transparency of income
tax disclosures by requiring companies to (1) disclose consistent categories and greater disaggregation of information in the effective
rate reconciliation and (2) provide information on income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal
years beginning after December 15, 2024, although early adoption is permitted. The guidance should be applied on a prospective basis
with the option to apply the standard retrospectively. We are currently evaluating what the potential impact of adopting this ASU 2023-09
could have on our consolidated financial statements and disclosures.&lt;/span&gt;&lt;/p&gt;

November 2023, the FASB issued ASU No. 2023-07, &#x201c;Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.&#x201d;
This ASU improves financial reporting by requiring disclosure of incremental segment information. The new guidance is effective for fiscal
years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is
permitted. The Company expects to provide incremental qualitative segment-related disclosures beginning with the Company&#x2019;s Annual
Report on Form 10-K for the fiscal year ended April 30, 2025.&lt;/span&gt;&lt;/p&gt;

(Subtopic 220-40): Disaggregation of Income Statement Expenses.&#x201d; This ASU improves the disclosures about a public business entity&#x2019;s
expenses and addresses requests from investors for more detailed information about the types of expenses in commonly presented expense
captions. The new guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning
after December 15, 2027. Early adoption is permitted. We are currently evaluating what the potential impact of adopting this ASU 2024-03

based on actual and projected revenues, over time revenue recognition, valuation consideration related to business combinations, including
contingent consideration based on actual and projected revenues, including discount rates and present values, and other assumptions and
estimates used to evaluate the recoverability of long-lived assets, goodwill and other intangible assets. Actual results could differ

accordance with Accounting Standards Codification 330 (ASC 330), inventory is stated at the lower of costs or net realizable value applicable

basis to cost of revenues, or moved to leased assets as applicable, following the matching principle where costs and revenues are recognized
in the same period. The Company has three classes of inventory; raw materials, work in process, and finished goods.&lt;/span&gt;&lt;/p&gt;

receivable are stated at the net amount expected to be collected. Amounts are usually due between 30 and 90 days after the invoice issuance.
The Company is exposed to credit losses primarily on accounts receivable and contract assets related to sales to customers. If applicable,
an allowance for credit losses is established to provide for the expected lifetime credit losses by evaluating factors such as customer
creditworthiness, historical payment and loss experiences, current economic conditions (including geographic and political risk), and
the age and status of outstanding receivables. Based on these factors, management has determined the allowance for credit losses of approximately
$&lt;span id="xdx_90E_eus-gaap--AllowanceForDoubtfulAccountsReceivableCurrent_iI_c20250131_zkSFicU5KQJb" title="Allowance for credit losses"&gt;100,000&lt;/span&gt;. Expected credit losses are written off in the period in which the financial assets are no longer collectible.&lt;/span&gt;&lt;/p&gt;

Company grants credit to its customers, generally, without collateral, under normal payment. Generally, invoicing occurs after the services
are performed or control of the product has transferred to the customer. Accounts receivable represent an unconditional right to consideration
arising from the Company&#x2019;s performance under contracts with customers.&lt;/span&gt;&lt;/p&gt;

and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is calculated using the
straight-line method over the estimated useful lives (three to ten years) of the assets. Leasehold improvements are amortized using the
straight-line method over the shorter of the estimated useful life of the asset or the remaining lease term. Expenses for maintenance
and repairs are charged to operations as incurred. Property and equipment is also reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows expected to be generated
by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, then an impairment charge is recognized in
the amount by which the carrying amount of the asset exceeds the fair value of the asset.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company accounts for revenue in accordance with Accounting Standards Codification 606 (ASC 606) for contracts with customers and Accounting
Standards Codification 842 (ASC 842) for leasing arrangements. In relation to ASC 606, which states that a performance obligation is
the unit of account for revenue recognition, the Company assesses the goods or services promised in a contract with a customer and identifies
as a performance obligation as either: a) a good or service (or a bundle of goods or services) that is distinct; or b) a series of distinct
goods or services that are substantially the same and that have the same pattern of transfer to the customer. A contract may contain
a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the Company
allocates the contracted transaction price to each performance obligation based upon the relative standalone selling price, which represents
the price the Company would sell a promised good or service separately to a customer. The Company determines the standalone selling price
based upon the facts and circumstances of each obligated good or service. When no observable standalone selling price is available, the
standalone selling price is generally estimated based upon the Company&#x2019;s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
nature of the Company&#x2019;s contracts may give rise to several types of variable consideration, including unpriced change orders, liquidated
damages and penalties. Variable consideration can also arise from modifications to the scope of services. Variable consideration is included
in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once
the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether
to include such amounts in the transaction price are based largely on the assessment of legal enforceability, performance, and any other
information (historical, current, and forecasted) that is reasonably available to us. There was no variable consideration as of January
31, 2025 or 2024. The Company presents shipping and handling costs, that occur after control of the promised goods or services transfer
to the customer, as fulfilment costs in costs of revenues and regular shipping and handling activities charged to operating expenses.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company recognizes revenue when or as it satisfies a performance obligation by transferring a good or service to a customer, either (1)
at a point in time or (2) over time. A good or service is transferred when or as the customer obtains control. The evaluation of whether
control of each performance obligation is transferred at a point in time or over time is made at contract inception. Input measures such
as costs incurred are utilized to assess progress against specific contractual performance obligations for the Company&#x2019;s services.
The selection of the method to measure progress towards completion requires judgment and is based on the nature of the services to be
provided. For the Company, the input method using costs or labor hours incurred best represents the measure of progress against the performance
obligations incorporated within the contractual agreements. If estimated total costs on any contract project a loss, the Company charges
the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated
costs to complete contracts, including penalties, change orders, claims, anticipated losses, and others are recorded in the accounting
period in which the events indicating a loss are known and the loss can be reasonably estimated. These loss projections are re-assessed
for each subsequent reporting period until the project is complete. Such revisions could occur at any time and the effects may be material.
During the nine-month period ended January 31, 2025, the Company recognized approximately $&lt;span id="xdx_903_eus-gaap--Revenues_pn5n6_c20240501__20250131__us-gaap--TimingOfTransferOfGoodOrServiceAxis__us-gaap--TransferredAtPointInTimeMember_zty46Mu42EBd"&gt;4.0

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s contracts are either cost-plus contracts, fixed-price contracts, time and material agreements, lease or service agreements.
Under cost plus contracts, customers are billed for actual expenses incurred plus an agreed-upon fee.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company has two types of fixed-price contracts, firm fixed-price and cost-sharing. Under firm fixed-price contracts, the Company receives
an agreed-upon amount for providing products and services specified in the contract, and a profit or loss is recognized depending on
whether actual costs are more or less than the agreed-upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the
customer is only intended to fund a portion of the costs on a specific project. Under cost-sharing contracts, an amount corresponding
to the revenue is recorded in cost of revenue, resulting in gross profit on these contracts of zero. The Company reports its disaggregation
of revenue by contract type since this method best represents the Company&#x2019;s business. For the nine-month periods ended January
31, 2025 and 2024, the majority of the Company&#x2019;s contracts were classified as firm fixed-price and the remainder were cost-sharing.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection
with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company&#x2019;s
accounts receivable balance is made up entirely of customer contract-related balances.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;The
Company&#x2019;s revenue also includes revenue from certain contracts which do not fall within the scope of ASC 606, but under the scope
of ASC 842, &#x201c;Leases&#x201d;. At inception of a contract for those classified under ASC 842, the Company classifies leases as either
operating or financing in accordance with the authoritative accounting guidance contained within ASC 842. If the direct financing or
sales-type classification criteria are met, then the lease is accounted for as a finance lease. All others are treated as operating leases.
The Company recognizes revenue from operating lease arrangements generally on a straight-line basis over the lease term, or as agreed
upon in-use days are utilized, which is presented in Revenues in the Consolidated Statement of Operations. The Company also enters into
lease arrangements for its PowerBuoys&#xae; and Wave Adaptive Modular Vessels (&#x201c;WAM-V&#xae;&#x201d;) with certain customers. Revenue
related to multiple-element arrangements is allocated to lease and non-lease elements based on their relative standalone selling prices
or expected cost plus a margin approach. Lease elements generally include a PowerBuoy&#xae;, WAM-V&#xae;, and components, while non-lease
elements, which the Company expects to become more prevalent, generally include engineering, monitoring and support services. In the
lease arrangement, the customer may be provided with an option to extend the lease term or purchase the leased buoy or WAM-V&#xae; at
some point during and/or at the end of the lease term.&lt;/span&gt;&lt;/p&gt;

customers are subject to ongoing credit evaluations based on payment history and other factors. If it is determined that collectability
of any portion of the contract value is not probable, an analysis of variable consideration will be performed using either the most likely
amount or expected value method to determine the amount of revenue that must be constrained until the scenario causing the variability
has been resolved.&lt;/span&gt;&lt;/p&gt;

is assessed for impairment using a qualitative or quantitative approach. The Company performs an annual impairment test of goodwill and
further periodic tests to the extent indicators of impairment develop between annual impairment tests. There were no indications of potential
impairment of goodwill identified for the nine months ended January 31, 2025 and 2024. Where the Company uses a qualitative analysis,
it considers factors that include historical financial performance, macroeconomic and industry conditions, and the legal and regulatory
environment. If the qualitative assessment indicates that it is more likely than not that an impairment exists, then a quantitative assessment
is also performed. The quantitative assessment requires an analysis of several estimates including future cash flows or income consistent
with management&#x2019;s strategic business plans, annual revenue growth rates and the selection of assumptions underlying a discount
rate (weighted average cost of capital) based on market data available at the time to determine the fair value of the Company. If the
fair value is less than the carrying amounts, an impairment charge for the difference is recorded. The Company acquired goodwill as part
of its purchase of MAR. Management performed its annual qualitative assessment in fiscal year 2024 and determined that it is more likely
than not that no goodwill impairment existed as of April 30, 2024.&lt;/span&gt;&lt;/p&gt;

attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective
tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary differences and operating loss and tax credit carry forwards
are expected to be recovered, settled or utilized. In assessing the realizability of deferred tax assets, management considers whether
it is more likely than not that some portion or all the deferred tax assets will not be realized. If such event occurs, a valuation allowance
is recorded. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes
the enactment date.&lt;/span&gt;&lt;/p&gt;

tax disclosures by requiring companies to (1) disclose consistent categories and greater disaggregation of information in the effective
rate reconciliation and (2) provide information on income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal
years beginning after December 15, 2024, although early adoption is permitted. The guidance should be applied on a prospective basis
with the option to apply the standard retrospectively. We are currently evaluating what the potential impact of adopting this ASU 2023-09

captions. The new guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning
after December 15, 2027. Early adoption is permitted. We are currently evaluating what the potential impact of adopting this ASU 2024-03
could have on our consolidated financial statements and disclosures.&lt;/span&gt;&lt;/p&gt;

assets include unbilled amounts typically resulting from arrangements whereby the right to payment is conditional on completing additional
tasks or services for a performance obligation. The increase in contract assets from year end is primarily a result of consulting services
projects for which revenue was recognized in the current period but has not yet been billed. No impairments to contract assets were incurred
during the nine months ended January 31, 2025 and 2024.&lt;/span&gt;&lt;/p&gt;

assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term
at commencement date. When the implicit rate of the lease is not provided or cannot be determined, the Company uses the incremental borrowing
rate based on the information available at the effective date to determine the present value of future payments. Lease terms may include
options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The renewal options
have not been included in the lease term as they are not reasonably certain of exercise. The Company&#x2019;s operating leases consist
of leases for office facilities and warehouse space. Lease expense for minimum lease payments is recognized on a straight- line basis
over the lease term and consists of interest on the lease liability and the amortization of the right of use asset.&lt;/span&gt;&lt;/p&gt;

Company estimates the fair value of each stock option award granted with service-based vesting requirements, using the Black-Scholes
option pricing model, assuming no dividends, and using weighted average valuation assumptions. The risk-free rate is based on the U.S.
Treasury yield curve in effect at the time of the grant commensurate with the expected life of the award. The expected life (estimated
period of time outstanding) of the stock options granted was estimated using the &#x201c;simplified&#x201d; method as permitted by the
SEC&#x2019;s Staff Accounting Bulletin No. 110, &lt;i&gt;Share-Based Payment.&lt;/i&gt; Expected volatility is based on the Company&#x2019;s historical
volatility over the expected life of the stock option granted. The Company did not grant any stock options during the nine months ended
January 31, 2025 and 2024, respectively.&lt;/span&gt;&lt;/p&gt;

Topic 820, &#x201c;&lt;i&gt;Fair Value Measurements&#x201d;&lt;/i&gt; states that fair value is an exit price, representing the amount that would be
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
Assets and liabilities that are measured at fair value are reported using a three-level fair value hierarchy that prioritizes the inputs
used to measure fair value. This hierarchy maximizes the use of observable input and minimizes the use of unobservable inputs. The following
is a description of the three hierarchy levels.&lt;/span&gt;&lt;/p&gt;

day of each calendar quarter and increased the principal amount of the Notes on a dollar-for-dollar basis. Upon the occurrence and during
the continuance of an event of default, the interest rate on the Notes will increase to &lt;span id="xdx_90E_eus-gaap--DebtInstrumentInterestRateIncreaseDecrease_pid_dp_c20241220__20241220__us-gaap--TypeOfArrangementAxis__custom--SecuritiesPurchaseAgreementMember__us-gaap--DebtInstrumentAxis__custom--InitialNoteMember_zcdR6Xp7j3W3" title="Increase in interest rate"&gt;17.5&lt;/span&gt;% per annum. Unless earlier converted, the
Notes will mature on the eighteen-month anniversary of their respective issuance dates. All amounts due under the Notes were convertible
at any time, in whole or in part, and subject to the Beneficial Ownership Cap, at the option of the holders into shares of common stock at a conversion price equal to the lower of the closing price of the common stock
on the trading day prior to each closing plus a 15% premium (the &#x201c;Reference Price&#x201d;) or 90% of the volume weighted average
price of the common stock during the seven trading days ending and including the trading day immediately preceding the delivery or deemed
delivery of the applicable conversion notice. Upon the satisfaction of certain
conditions, we could have prepaid outstanding Notes upon not less than 20 business days nor more than 30 business days&#x2019; written
notice by paying an amount equal to the face value of the Notes at a premium of &lt;span id="xdx_904_ecustom--DebtInstrumentPremiumPercentage_pid_dp_c20241220__20241220__us-gaap--TypeOfArrangementAxis__custom--SecuritiesPurchaseAgreementMember__us-gaap--DebtInstrumentAxis__custom--InitialNoteMember_zeELrLdAh52a" title="Premium percentage"&gt;15&lt;/span&gt;%.&lt;/span&gt;&lt;/p&gt;

Initial Note contained certain terms and conditions which management evaluated as potential embedded derivatives. Management determined
that the optional conversion feature is not clearly and closely related to the debt host instrument, and therefore required bifurcation
and separate accounting. We determined the fair value of the embedded derivative as approximately $&lt;span id="xdx_908_eus-gaap--DerivativeGainLossOnDerivativeNet_pn5n6_c20241220__20241220__us-gaap--TypeOfArrangementAxis__custom--SecuritiesPurchaseAgreementMember__us-gaap--DebtInstrumentAxis__custom--InitialNoteMember_zEar43yvhlAh" title="Derivative liability"&gt;0.4&lt;/span&gt; million and recorded it as a discount

Company underwent an income tax audit in Spain for the period from 2011 to 2014, when its Spanish branch was closed. On July 30, 2018,
the Spanish tax inspector concluded that although there was no tax owed in light of losses reported, the Company&#x2019;s Spanish branch
owed penalties for failure to properly account for the income associated with the funding grant. During the year ended April 30, 2022,
the Company received notice from the Spanish Central Economic and Administrative Tribunal (&#x201c;Spanish Tax Administration&#x201d;)
that it agreed with the inspector and ruled that the Company owes the full amount of the penalty in the amount of &#x20ac;&lt;span id="xdx_907_eus-gaap--IncomeTaxExaminationPenaltiesAndInterestAccrued_iI_uEuro_c20220430__us-gaap--IncomeTaxAuthorityNameAxis__us-gaap--TaxAuthoritySpainMember_ziQsbbaztifg" title="Income tax penalties"&gt;279,870&lt;/span&gt; or approximately

Notwithstanding that payment, on April
30, 2022, the Company filed its appeal of the decision of the Central Court to the Spanish National Court. On February 3, 2025, the Spanish
National Court denied the Company&#x2019;s appeal, and the Company does not believe it has further available grounds to appeal this decision
to the Spanish Supreme Court. Accordingly, this matter is closed.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;On
October 10, 2023, Paragon Technologies, Inc. filed a complaint in the Court of Chancery of the State of Delaware against the Company,
and the members of its Board of Directors, claiming certain breaches of their fiduciary duties. The complaint sought only injunctive
relief against the Company, and not monetary damages, and therefore the financial exposure derived therein was limited to applicable
legal fees and costs at that stage, which was material to FY&#x2019; 24. On November 2, 2023, Paragon sought leave to amend its complaint
to add additional claims. The Court granted this motion for leave to amend, provided that the Court would not delay the hearing on the
matters raised in the initial complaint, which was set for November 28, 2023. This hearing on the initial complaint was held and on November
30, 2023, the Court ruled in favor of the Company and denied Paragon&#x2019;s motion for injunctive relief. The status of the in the amended
complaint is still pending. On February 28, 2024, the Company successfully finalized its 2023 annual meeting of stockholders in spite
of Paragon&#x2019;s repeated attempts to contest the meeting. In an August 12, 2024 Press Release and its Form 10-Q report for the second
quarter of 2024, Paragon announced that it was no longer pursuing litigation against the Company. Pursuant to a Court order dated January
9, 2025, Paragon was required &#x201c;to file a status report within 30 days. Otherwise, the case will be dismissed under Rule 41(e).&#x201d;
Because Paragon did not file a status report by February 10, 2025, the Company anticipates that the Court will dismiss the case, with
prejudice, due to Paragon&#x2019;s failure to prosecute.&lt;/span&gt;&lt;/p&gt;

February 2025, the Company received a shareholder demand under Section 220 of the General Corporation Law of the State of Delaware for
inspection of certain books and records relating to prior equity grants made to officers and directors under the 2015 Plan in January
2023, February 2024 and January 2025. The Company is reviewing and considering the demand and engaging with counsel for the shareholder.
The Company has not recorded any material liability for these matters as of January 31, 2025 as it cannot estimate the ultimate outcome
at this time.&lt;/span&gt;&lt;/p&gt;

estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision
when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company
estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not
misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial
statements.&lt;/span&gt;&lt;/p&gt;

Company accounts for income taxes in accordance with ASC 740. The guidance requires the Company to recognize in its consolidated financial
statements the impact of a tax position if that position is more likely than not to be sustained upon examination, based on the technical
merits of the position. The Company has no current or deferred tax due to current and projected losses for the year. The Company previously
appealed the results of the income tax audit in Spain for the period from 2011 to 2014, when the Company&#x2019;s Spanish branch was closed
(see Note 14). On February 3, 2025, the Spanish National Court denied the Company&#x2019;s appeal, and the Company does not believe it
has further available grounds to appeal this decision to the Spanish Supreme Court. Accordingly, this matter is closed. At January 31,
2025, the Company had no uncertain tax positions. The Company does not expect any material increase or decrease in its income tax expense
or benefit in the next twelve months, related to examinations or uncertain tax positions. Net operating loss and credit carry forwards
since inception remain open to examination by taxing authorities and will continue to remain open for a period of time after utilization.&lt;/span&gt;&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;In
June 2023, in order to protect the Company&#x2019;s valuable tax assets related to its net operating losses from being limited or lost
under Section 382 of the Internal Revenue Code, the Company adopted a Tax Benefits Preservation Plan (the &#x201c;Plan&#x201d;). Pursuant
to the Plan, the Board declared a dividend of one preferred share purchase right (each, a &#x201c;Right&#x201d;) for each outstanding share
of common stock of the Company. The dividend was distributed to stockholders of record as of the close of business on July 11, 2023.
The Plan substantially diminishes the risk that the Company&#x2019;s ability to utilize its net operating loss carryovers to reduce potential
future federal income tax obligations may become substantially limited. The Plan is intended to act as a deterrent to any person or group
acquiring beneficial ownership of &lt;span id="xdx_904_ecustom--BusinessAcquisitionOutstandingCommonStockOwnershipPercentage_iI_dp_uPure_c20230630_zDmtx0mgBXmc" title="Acquisition outstanding common stock ownership percentage"&gt;4.99&lt;/span&gt;% or more of the outstanding common stock without approval by potentially subjecting any such person
or group to significant dilution. The Plan was approved by shareholders by a non-binding advisory vote at the Company&#x2019;s Annual
Meeting held on February 28, 2024.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Company determined the grant date fair value of the Rights using an option-pricing model. The amount was immaterial to the consolidated
financial statements and deemed to be de minimis, and accordingly was not recorded to the financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

order to monetize their attributes, the Company has historically sold the Net Operating Losses (NOL&#x2019;s) and R&amp;amp;D credit generated
in New Jersey. In September 2024 the Company was notified that it received a preliminary award of approximately $&lt;span id="xdx_901_eus-gaap--IncomeTaxPaidForeignBeforeRefundReceived_pn5n6_c20240901__20240930_zooIs7kkjorb" title="Preliminary award received"&gt;1.1&lt;/span&gt; million for New
Jersey State for the sale of the fiscal year 2024 NOL. The final allocation is expected to be determined during the fourth quarter of
OPT&#x2019;s 2025 fiscal year when the sale of the NOL&#x2019;s and credit are finalized. The Company has elected to recognize the gain
on the sale as a component of tax expense at the time of the sale. Historically the Company has received over 90% of the amount of the
preliminary award upon final sale.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

enough to justify segment reporting or to make it meaningful to investors, and the Company&#x2019;s chief operating decision maker does
not view the Company&#x2019;s operations on a segment basis. The Company operates worldwide, with its U.S. operations in New Jersey and
California and one operating subsidiary in the UK. Revenues and expenses are generally attributed to the operating unit that bills the
customers. During each of the three and nine months ended January 31, 2025 and 2024, the Company&#x2019;s primary business operations
were in North America, South America, EMEA and Asia/Australia.&lt;/span&gt;&lt;/p&gt;
