Power Technologies, Inc. (the &#8220;Company&#8221;) was founded in 1984 in New Jersey, commenced business operations in 1994 and re-incorporated
in Delaware in 2007. We provide ocean data collection and reporting, marine power, offshore communications and Domain Awareness Systems
(&#8220;MDA&#8221; or &#8220;MDAS&#8221;) products, integrated solutions, and consulting services. Our solutions focus on four major
service areas: Data as a Service (&#8220;DaaS&#8221;), which includes data collected by our Wave Adaptive Modular Vessel (WAM-V&#174;)
autonomous vehicles or our PowerBuoy&#174; product lines; Robotics as a Service (&#8220;RaaS&#8221;), which provides a lower cost subscription
model for our customers to access use of our WAM-V&#8217;s&#174;; Power as a Service (&#8220;PaaS&#8221;), which includes our PowerBuoy&#174;
and subsea battery products; and our Strategic Consulting Services. We offer our 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. We are involved in the
entire life cycle of product development, from product design through manufacturing, testing, deployment, maintenance and upgrades, while
working closely with partners across our supply chain. Our solutions are based on technologies that enable autonomous, zero or low carbon
emitting, and cost effective data collection, analysis, transportation and communication. Our 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.
We then channel the information we collect, and other communications, through control equipment linked to edge computing and cloud hosting
environments. Our goal is to generate most of our revenues from the sale or lease of our products and solutions, and sales of services
to support our business operations. As we continue to develop and commercialize our products and services, we expect to have a net decrease
in cash due to the use of cash from operating activities unless and until we achieve positive cash flow from the commercialization of
products, solutions and services.</span></p>

receivable are stated at the net amount expected to be collected. Amounts are ordinarily due between 30 and 90 days after the issuance of the invoice. We are exposed to credit losses primarily on our accounts receivable and contract assets related to our 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 was immaterial. Expected credit losses are written off in the period in which the financial asset is no longer collectible.</span></p>

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.</span></p>

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&#8217;s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.</span></p>

nature of the Company&#8217;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. Our estimates of variable consideration and determination of
whether to include such amounts in the transaction price are based largely on our 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 July 31, 2023 or 2022. The Company presents shipping and handling costs, that occur after control of the promised goods or services
transfer to the customer, as fulfillment costs in costs of goods sold and regular shipping and handling activities charged to operating
expenses.</span></p>

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&#8217;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.</span></p>

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&#8217;s share of the
costs is recorded as product development expense. The Company reports its disaggregation of revenue by contract type since this method
best represents the Company&#8217;s business. For the three-month periods ended July 31, 2023 and 2022, the majority of the Company&#8217;s
contracts were classified as firm fixed-price and the remainder were cost-sharing.</span></p>

<p style="margin: 0; text-align: justify">The Company&#8217;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&#8217;s accounts receivable balance is made up entirely of customer contract related balances.</p>

Company&#8217;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. 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 Topic 842, &#8220;Leases&#8221;. 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 Revenue in the Consolidated Statement of Operations. The Company also enters
into lease arrangements for its PowerBuoys&#174; and Wave Adaptive Modular Vessels (&#8220;WAM-V&#174;&#8221;) 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&#174;, WAM-V&#174;, 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&#174;
at some point during and/or at the end of the lease term.</span></p>

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. Where the Company use 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&#8217;s
strategic business plans, annual sales 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 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 2023 and determined that it is more likely than not that no goodwill impairment existed
as of April 30, 2023.</span></p>

taxes are accounted for under ACS 740 utilizing the asset and liability method. Deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities

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

agreements. No impairments to contract assets were incurred during the three months ended July 31, 2023 or July 31, 2022.</span></p>

asset 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&#8217;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.</span></p>

Topic 820, &#8220;<i>Fair Value Measurements&#8221;</i> 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

solutions deliver value to customers by utilizing our managed power platforms. We continue to develop and commercialize our proprietary
power platforms that generate electricity primarily by harnessing the renewable energy of ocean waves. We continue to offer our commercial
PB3 and are adding solar power options to our next generation PowerBuoy&#174; (the &#8220;NextGen PB&#8221;) and have the option of adding
small wind turbines to supplement power generation. The NextGen PB includes versions with and without a wave energy converter (WEC),
with the non-WEC version replacing our previous hybrid PB. We also continue to offer our commercialized subsea battery for subsea power
applications and as additional storage when combined with our buoy platforms. Our focus for these solutions is on bringing autonomous
clean power to our customers wherever it is required. Moreover, offshore data and communications networks require power to function,
and our solution solves this need without requiring ongoing battery replacement or older technologies such as shore station power cables.
Many of the lessons learned from the deployments of both our PB3 and PB 2.0 are being used to develop the next generation of PowerBuoy&#174;

PB3 uses proprietary technologies that convert the hydrokinetic energy of ocean waves into electricity. The PB3 features a unique onboard
power take-off (&#8220;PTO&#8221;) system which incorporates both energy storage and energy management and control systems. The PB3 generates
a nominal nameplate capacity rating of up to 3 kilowatts (&#8220;kW&#8221;) of peak power. Power generation is deployment-site dependent,
as wave activity impacts power generation. Our Energy Storage System (&#8220;ESS&#8221;) has a capacity of up to a nominal 150 kW-hours
to meet specific application requirements.</span></p>

PB3 is designed to generate power for use independent of the power grid in offshore locations. The hull consists of a main spar structure
compliantly moored to the seabed and surrounded by a floating annular structure that can freely move up and down in response to the passage
of the waves. The PTO system includes a mechanical energy conversion system, an electrical generator, a power electronics system, our
control system, and our ESS which is sealed within the hull. As ocean waves pass the PB3 the mechanical stroke action created by the
rising and falling of the waves is converted into rotational mechanical energy by the PTO, which in turn, drives the electric generator.
The power electronics system then conditions the electrical output which is stored within the ESS.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
operation of the PB3 is controlled by our customized, proprietary control system. The control system uses sensors and an onboard computer
to continuously monitor the PB3 subsystems. We believe that this ability to optimize and manage the electric power output of the PB3
is a significant advantage of our technology. In the event of large storm waves, the control system automatically locks the PB3, and
electricity generation is suspended. However, the load center (either the on-board payload or one in the vicinity of the PB3) may continue
to receive power from the ESS. When wave heights return to normal operating conditions, the control system automatically unlocks the
PB3 and electricity generation and ESS replenishment recommences. This safety feature helps to protect the PB3 from being damaged by
storms.</span></p>

solutions are also available for the PB3 including the addition of subsea sensors to monitor for acoustic signatures, tsunami activity,
and water quality. In addition, in August 2023 we successfully demonstrated a WAM-V attaching itself remotely to a buoy and establishing
a connection that will enable charging. This successful electrical connection that enabled charging represents a significant step forward
in the integration of renewable energy sources within the maritime industry and paves the way for a future where electrically propelled
autonomous vessels can operate for extended durations, opening doors to potential new applications within the maritime domain.</span></p>

NextGen PB is an alternative platform to the PB3, and will consist of multiple versions, one utilizing solar and wind power and one utilizing
solar and wind power plus wave energy conversion capability, to provide reliable power in remote offshore locations, regardless of ocean
wave conditions. The WEC technology in the NextGen PB is based on our ongoing Mass on Spring Wave Energy Converter (MOSWEC) development
which has the advantages of smaller size, lower cost, environmentally sealed design, and increased energy generation capability. The
prototype of the solar and wind PowerBuoy&#174; has been tested off the coast of New Jersey and was used during the MDAS demonstration
for ANTX during fiscal 2023. We believe this product addresses a broader spectrum of customer deployment needs, including low-wave and
nearshore environments, with the potential for greater product integration within each customer project. The NextGen PB is intended to
provide a stable energy platform for our MDAS solution, and for agile deployment of subsea power applications, such as a surface communications
hub for electric remotely operated vehicles (&#8220;eROV&#8221;) and autonomous underwater vehicles (&#8220;AUV&#8221;) used for underwater
inspections and short-term maintenance, and subsea equipment monitoring and control. The design has a high payload capacity for surveillance
and communications equipment, including subsea acoustics, with the capability of being tethered to subsea payloads such as batteries,
or with a conventional anchor mooring system. Energy is stored in onboard lithium ion batteries which can power subsea and topside payloads.
The control system uses sensors and an onboard computer to continuously monitor the subsystems. The NextGen PB is designed to be able
to operate over a broad range of temperature and ocean wave conditions. It has a 40kW-hour battery system which can be expanded up to
120 kW-hour energy. The Company expects both versions of the NextGen PB to be completed and commercially available by the end of fiscal
2024.</span></p>

on our recent market analysis, several emerging themes are shaping the offshore MDA sector for commercial and defense applications, as
highlighted by the National Plan to achieve MDA released by the Department of Homeland Security (&#8220;DHS&#8221;) and the Government
Accountability Office (&#8220;GAO&#8221;) in their &#8216;Unmanned Maritime Systems&#8217; 2022 report on Maritime Security. In March
2023, the United States Coast Guard released its Unmanned Systems Strategic Plan with a stated vision to effectively employ, defend against,
and regulate unmanned systems in a complex maritime environment advancing maritime safety, security, and prosperity for the American
public. Coast Guard mission execution often begins with awareness of what is happening in the maritime domain. Surveillance, detection,
classification, identification, and prosecution are enduring, high-level capabilities that the Coast Guard needs in order to execute
its statutory missions and we believe that the Company&#8217;s products are well positioned to enable the Coast Guard to accomplish this
mission. Large defense contractors are also expanding into the &#8220;ocean data collection&#8221; space by acquiring small and mid-size
unmanned and autonomous surface and subsea vehicle companies. Unmanned systems are increasingly in demand by defense and security and
commercial companies to reduce costs and improve safety in offshore operations. Also, geopolitical developments such as the need for
countries to protect their exclusive economic zones from illegal fishing activities and protect natural resources on the seabed are accelerating
the adoption of solutions or technologies that collect, transmit, and synthesize data to provide actionable intelligence and decision-advantage
to clients. Our recent operations in Bahrain and in the Asia Pacific region show the broadening geographic opportunity for our services.
For example, in its &#8216;Technology Outlook 2030&#8217;, Det Norske Veritas, Inc, (&#8220;DNV&#8221;), a leading operator of quality
assurance and risk management in maritime, oil and gas and the energy industries, observed that all-electric systems are gaining popularity
in subsea applications due to their cost-efficiency and reduced environmental impact. DNV predicts that all-electric subsea systems will
play a critical role in the industry&#8217;s transition to a more sustainable future. These trends reinforce the increasing need for
products, solutions, and services in the offshore maritime domain awareness sector, particularly for unmanned and sentinel systems that
can improve safety and reduce costs.</span></p>

The Company has previously entered into business relationships focused on including, but not limited to, deployment and installations,
sourcing of surface payloads, and integration with autonomous vehicles. To augment our own internal software development team and further
develop the MDAS, we maintain ongoing strategic software and robotics partnerships with software companies. We believe the business relationships
with these software companies will further the development, alongside our internal technology resources, of our next-generation MDAS

infrastructure, and web-based user interface. The platform was designed with a flexible architecture that allows the Company to integrate
new sensor technologies and third-party analytics capabilities and share MDAS data with customers and partners. During fiscal 2024, the
Company plans to decrease its reliance on third-party software parties through increased support from its internal software team.</span></p>

demonstration projects have been a requisite step towards broad solution deployment and revenues associated with specific applications
such as our New Jersey MDAS test array as part of our DaaS solution and to highlight these capabilities. Customers may want their own
dedicated demonstration depending on customer needs. During a typical demonstration project&#8217;s specification, negotiation and evaluation
period, we are often subject to the prospective customer&#8217;s vendor qualification process, which entails substantial due diligence
of the Company and its capabilities. Such demonstrations are often a required step prior to leasing and may include negotiation of standard
terms and conditions. Many proposals contain provisions which would provide the option to purchase or lease our PowerBuoy&#174; or WAM-V&#174;
product upon successful conclusion of the demonstration project. The Company maintains a fleet of WAM-Vs&#174; dedicated to demonstrations
and has successfully demonstrated the capabilities of many of its solutions on its own or in customer-sponsored evaluation projects and
remains focused on further demonstrations to build customer awareness and confidence and to drive revenue.</span></p>

                                            WAM-Vs&#174; are increasingly focused on the defense and security, hydrographic survey, and
                                            surveillance industries and well positioned to capitalize on the growing demand for unmanned
                                            surface vehicles to provide maritime safety, security, and awareness of what is happening
                                            in the maritime domain, including surveillance, detection, classification, and identification.
                                            The ability of our WAM-Vs&#174; to handle various payloads allows us to target navigation

                                            for the launch of aerial drones and underwater survey equipment. WAM-Vs&#174; are easily and
                                            economically shipped via land, air, or sea, and their modular design enables us to quickly

$8.0 million. The Company has continued to make investments in ongoing product development efforts and in building inventory in anticipation
of, and in support of, future growth. The Company&#8217;s future results of operations involve significant risks and uncertainties. Factors
that could affect the Company&#8217;s future operating results and could cause actual results to vary materially from expectations include,

products that it may develop, 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. Management
believes the Company&#8217;s cash balance of $3.9 million and short term investments balance of $22.8 million at July 31, 2023 is sufficient
to fund its planned operations through at least September 2024.</span></p>

statements in accordance with U.S. Generally Accepted Accounting Principles (&#8220;U.S. GAAP&#8221;). The preparation of financial statements
also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, costs and expenses and related
disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the
circumstances. Actual results could differ significantly from the estimates made by our management. To the extent that there are differences
between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and
cash flows will be affected. We believe that accounting policies are critical to understanding our historical and future performance,
as these policies relate to the more significant areas involving management&#8217;s judgments and estimates.</span></p>

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&#8217;s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.</span></p>

nature of the Company&#8217;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. Our estimates of variable consideration and determination of
whether to include such amounts in the transaction price are based largely on our 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 July 31, 2023 or 2022. The Company presents shipping and handling costs, that occur after control of the promised goods or services
transfer to the customer, as fulfillment costs in costs of goods sold and regular shipping and handling activities charged to operating
expenses.</span></p>

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&#8217;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 projects 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 three-month period ended July 31, 2023, the
Company recognized approximately $0.5 million in revenue related to performance obligations satisfied at a point in time and
approximately $0.8 million in revenue related to performance obligations satisfied over-time.</span></p>

Company&#8217;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.</span></p>

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&#8217;s share of the
costs is recorded as product development expense. The Company reports its disaggregation of revenue by contract type since this method
best represents the Company&#8217;s business. For the the three months ended July 31, 2023 and 2022, the majority of the Company&#8217;s
contracts were classified as firm fixed-price and the balance were cost-sharing.</span></p>

Company&#8217;s revenue also includes revenue from certain contracts which do not fall within the scope of ASC 606, but under the ASC
842. 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 Topic 842, &#8220;Leases&#8221;. 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 Revenue in the Consolidated Statement of Operations. The Company also enters into
lease arrangements for its PowerBuoys&#174; and WAM-V&#174; 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&#174;, WAM-V&#174;, 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&#174; at some point during and/or at the end of
the lease term.</span></p>

Power Technologies, Inc. (the &#8220;Company&#8221;) was founded in 1984 in New Jersey, commenced business operations in 1994 and re-incorporated
in Delaware in 2007. We provide ocean data collection and reporting, marine power, offshore communications and Domain Awareness Systems
(&#8220;MDA&#8221; or &#8220;MDAS&#8221;) products, integrated solutions, and consulting services. Our solutions focus on four major
service areas: Data as a Service (&#8220;DaaS&#8221;), which includes data collected by our Wave Adaptive Modular Vessel (WAM-V&#174;)
autonomous vehicles or our PowerBuoy&#174; product lines; Robotics as a Service (&#8220;RaaS&#8221;), which provides a lower cost subscription
model for our customers to access use of our WAM-V&#8217;s&#174;; Power as a Service (&#8220;PaaS&#8221;), which includes our PowerBuoy&#174;
and subsea battery products; and our Strategic Consulting Services. We offer our 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. We are involved in the
entire life cycle of product development, from product design through manufacturing, testing, deployment, maintenance and upgrades, while
working closely with partners across our supply chain. Our solutions are based on technologies that enable autonomous, zero or low carbon
emitting, and cost effective data collection, analysis, transportation and communication. Our 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.
We then channel the information we collect, and other communications, through control equipment linked to edge computing and cloud hosting
environments. Our goal is to generate most of our revenues from the sale or lease of our products and solutions, and sales of services
to support our business operations. As we continue to develop and commercialize our products and services, we expect to have a net decrease
in cash due to the use of cash from operating activities unless and until we achieve positive cash flow from the commercialization of
products, solutions and services.</span></p>

receivable are stated at the net amount expected to be collected. Amounts are ordinarily due between 30 and 90 days after the issuance of the invoice.

Based on these factors, management has determined the allowance for credit losses was immaterial.

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.</span></p>

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&#8217;s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.</span></p>

nature of the Company&#8217;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. Our estimates of variable consideration and determination of
whether to include such amounts in the transaction price are based largely on our 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 July 31, 2023 or 2022. The Company presents shipping and handling costs, that occur after control of the promised goods or services
transfer to the customer, as fulfillment costs in costs of goods sold and regular shipping and handling activities charged to operating
expenses.</span></p>

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&#8217;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.</span></p>

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&#8217;s share of the
costs is recorded as product development expense. The Company reports its disaggregation of revenue by contract type since this method
best represents the Company&#8217;s business. For the three-month periods ended July 31, 2023 and 2022, the majority of the Company&#8217;s
contracts were classified as firm fixed-price and the remainder were cost-sharing.</span></p>

<p style="margin: 0; text-align: justify">The Company&#8217;s contract assets and liabilities primarily relate to the timing differences between cash received

Company&#8217;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. 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 Topic 842, &#8220;Leases&#8221;. 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 Revenue in the Consolidated Statement of Operations. The Company also enters
into lease arrangements for its PowerBuoys&#174; and Wave Adaptive Modular Vessels (&#8220;WAM-V&#174;&#8221;) 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&#174;, WAM-V&#174;, 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&#174;
at some point during and/or at the end of the lease term.</span></p>

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. Where the Company use 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&#8217;s
strategic business plans, annual sales 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 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 2023 and determined that it is more likely than not that no goodwill impairment existed
as of April 30, 2023.</span></p>

taxes are accounted for under ACS 740 utilizing the asset and liability method. Deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities

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.</span></p>

June 2016, the Financial Accounting Standards Board (&#8220;FASB&#8221;) issued ASU No. 2016-13, &#8220;<i>Financial Instruments </i>-
<i>Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.&#8221; </i>This amendment replaces the incurred
loss impairment methodology in current GAAP with a methodology that reflects expected credit losses on instruments within its scope,
including trade receivables. This update is intended to provide financial statement users with more decision-useful information about
the expected credit losses. In November 2019, the FASB issued No. 2019-10, <i>Financial Instruments&#8212;Credit Losses (Topic 326),
Derivatives and Hedging (Topic 815), and Leases (Topic 842)</i>, which deferred the effective date of ASU 2016-13 for Smaller Reporting
Companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company has evaluated
the impact on its consolidated financial statements from the adoption of ASU 2016-13, and has determined there is no material impact.</span></p>

asset and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term

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&#8217;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.</span></p>

Topic 820, &#8220;<i>Fair Value Measurements&#8221;</i> 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.</span></p>

the Spanish tax inspector concluded that although there was no tax owed in light of losses reported, the Company&#8217;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 (&#8220;Spanish Tax Administration&#8221;)

account 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 has appealed
the results of the income tax audit in Spain for the period from 2011 to 2014, when the Company&#8217;s Spanish branch was closed (see Note 14). At July 31, 2023, 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.</span></p>

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.</span></p>

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&#8217;s forecast of the total cost to satisfy the performance
obligation plus an appropriate profit margin.</span></p>

nature of the Company&#8217;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. Our estimates of variable consideration and determination of
whether to include such amounts in the transaction price are based largely on our 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 July 31, 2023 or 2022. The Company presents shipping and handling costs, that occur after control of the promised goods or services
transfer to the customer, as fulfillment costs in costs of goods sold and regular shipping and handling activities charged to operating
expenses.</span></p>

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&#8217;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.</span></p>

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&#8217;s share of the
costs is recorded as product development expense. The Company reports its disaggregation of revenue by contract type since this method
best represents the Company&#8217;s business. For the three-month periods ended July 31, 2023 and 2022, the majority of the Company&#8217;s
contracts were classified as firm fixed-price and the remainder were cost-sharing.</span></p>

<p style="margin: 0; text-align: justify">The Company&#8217;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&#8217;s accounts receivable balance is made up entirely of customer contract related balances.</p>

Company&#8217;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. 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 Topic 842, &#8220;Leases&#8221;. 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 Revenue in the Consolidated Statement of Operations. The Company also enters
into lease arrangements for its PowerBuoys&#174; and Wave Adaptive Modular Vessels (&#8220;WAM-V&#174;&#8221;) 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&#174;, WAM-V&#174;, 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&#174;
at some point during and/or at the end of the lease term.</span></p>

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. Where the Company use 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&#8217;s
strategic business plans, annual sales 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 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 2023 and determined that it is more likely than not that no goodwill impairment existed
as of April 30, 2023.</span></p>

taxes are accounted for under ACS 740 utilizing the asset and liability method. Deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities

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

loss impairment methodology in current GAAP with a methodology that reflects expected credit losses on instruments within its scope,
including trade receivables. This update is intended to provide financial statement users with more decision-useful information about
the expected credit losses. In November 2019, the FASB issued No. 2019-10, <i>Financial Instruments&#8212;Credit Losses (Topic 326),
Derivatives and Hedging (Topic 815), and Leases (Topic 842)</i>, which deferred the effective date of ASU 2016-13 for Smaller Reporting

the impact on its consolidated financial statements from the adoption of ASU 2016-13, and has determined there is no material impact.</span></p>

Generally, only investments with original maturities of three months or less qualify as cash equivalents by definition. Original maturity means an original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months.</p></div>

Power Technologies, Inc. (the &#x201c;Company&#x201d;) was founded in 1984 in New Jersey, commenced business operations in 1994 and re-incorporated
in Delaware in 2007. We provide ocean data collection and reporting, marine power, offshore communications and Domain Awareness Systems
(&#x201c;MDA&#x201d; or &#x201c;MDAS&#x201d;) products, integrated solutions, and consulting services. Our solutions focus on four major
service areas: Data as a Service (&#x201c;DaaS&#x201d;), which includes data collected by our Wave Adaptive Modular Vessel (WAM-V&#xae;)
autonomous vehicles or our PowerBuoy&#xae; product lines; Robotics as a Service (&#x201c;RaaS&#x201d;), which provides a lower cost subscription
model for our customers to access use of our WAM-V&#x2019;s&#xae;; Power as a Service (&#x201c;PaaS&#x201d;), which includes our PowerBuoy&#xae;
and subsea battery products; and our Strategic Consulting Services. We offer our 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. We are involved in the
entire life cycle of product development, from product design through manufacturing, testing, deployment, maintenance and upgrades, while
working closely with partners across our supply chain. Our solutions are based on technologies that enable autonomous, zero or low carbon
emitting, and cost effective data collection, analysis, transportation and communication. Our 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.
We then channel the information we collect, and other communications, through control equipment linked to edge computing and cloud hosting
environments. Our goal is to generate most of our revenues from the sale or lease of our products and solutions, and sales of services
to support our business operations. As we continue to develop and commercialize our products and services, we expect to have a net decrease
in cash due to the use of cash from operating activities unless and until we achieve positive cash flow from the commercialization of
products, solutions and services.&lt;/span&gt;&lt;/p&gt;

million. Cash used in operations includes payments of the MAR earnout payable and payment of the fiscal 2023 bonus for all employees, both of which
were accrued as of April 30, 2023. The Company has continued to make investments in ongoing product development efforts and to build
inventory in anticipation of, and to support, future growth. 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. For the three months ended July 31, 2023 and through
the date of filing of this Form 10-Q, management has not obtained any material additional capital financing. Management believes the
Company&#x2019;s current cash balance at July 31, 2023 of $&lt;span id="xdx_907_eus-gaap--Cash_iI_pn5n6_c20230731_zE7UswOiKqz3" title="Cash"&gt;3.9&lt;/span&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 revenues and expenses during the period. Significant items subject to such estimates and assumptions include, among other
items, stock-based compensation, over-time revenue recognition, valuation consideration related to business combinations, including contingent
consideration, 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;

Standards Update (&#x201c;ASU&#x201d;) No. 2015-16, Business Combinations (Topic 805). The Company allocates the fair value of consideration
transferred in a business combination to the estimated fair value at the acquisition date of the tangible and intangible assets acquired
as well as the liabilities assumed. Acquisition costs are expensed as incurred. Any excess consideration transferred is recorded as goodwill
and in instances where the fair value of consideration transferred is less than the estimated fair value of tangible and intangible assets
acquired less liabilities assumed, such amounts are recorded as a gain on the bargain purchase.&lt;/span&gt;&lt;/p&gt;

accordance with ASC 330, inventory is stated at the lower of costs or net realizable value applicable to goods on hand remaining after
the matching of absorbed costs with concurrent revenues. The Company has three classes of inventory; raw materials, work in process,

basis to cost of good sold, or moved to leased assets as applicable.&lt;/span&gt;&lt;/p&gt;

receivable are stated at the net amount expected to be collected. Amounts are ordinarily due between 30 and 90 days after the issuance of the invoice. We are exposed to credit losses primarily on our accounts receivable and contract assets related to our 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 was immaterial. Expected credit losses are written off in the period in which the financial asset is no longer collectible.&lt;/span&gt;&lt;/p&gt;

Company grants credit to its customers, generally, without collateral, under normal payment terms (typically 30 to 90 days after invoicing).
Generally, invoicing occurs after the services are performed or control of the product has transferred to the customer. Accounts receivable

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 0pt 0pt 0; 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;

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. Our estimates of variable consideration and determination of
whether to include such amounts in the transaction price are based largely on our 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 July 31, 2023 or 2022. The Company presents shipping and handling costs, that occur after control of the promised goods or services
transfer to the customer, as fulfillment costs in costs of goods sold 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 0pt 0pt 0; 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;/span&gt;&lt;/p&gt;

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 0pt 0pt 0; 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 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&#x2019;s share of the
costs is recorded as product development expense. The Company reports its disaggregation of revenue by contract type since this method
best represents the Company&#x2019;s business. For the three-month periods ended July 31, 2023 and 2022, 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="margin: 0; text-align: justify"&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;/p&gt;

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. 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 Topic 842, &#x201c;Leases&#x201d;. 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 Revenue 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

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. Where the Company use 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 sales 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 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 2023 and determined that it is more likely than not that no goodwill impairment existed
as of April 30, 2023.&lt;/span&gt;&lt;/p&gt;

taxes are accounted for under ACS 740 utilizing the asset and liability method. Deferred tax assets and liabilities are recognized for
the future tax consequences 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;

Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained upon examination.
Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition

tax benefits in interest expense and penalties in selling, general, and administrative expenses, to the extent incurred. Refer to Note

&lt;i&gt;Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.&#x201d; &lt;/i&gt;This amendment replaces the incurred
loss impairment methodology in current GAAP with a methodology that reflects expected credit losses on instruments within its scope,
including trade receivables. This update is intended to provide financial statement users with more decision-useful information about
the expected credit losses. In November 2019, the FASB issued No. 2019-10, &lt;i&gt;Financial Instruments&#x2014;Credit Losses (Topic 326),
Derivatives and Hedging (Topic 815), and Leases (Topic 842)&lt;/i&gt;, which deferred the effective date of ASU 2016-13 for Smaller Reporting
Companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company has evaluated
the impact on its consolidated financial statements from the adoption of ASU 2016-13, and has determined there is no material impact.&lt;/span&gt;&lt;/p&gt;

items, stock-based compensation, over-time revenue recognition, valuation consideration related to business combinations, including contingent
consideration, 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;

the matching of absorbed costs with concurrent revenues. The Company has three classes of inventory; raw materials, work in process,

basis to cost of good sold, or moved to leased assets as applicable.&lt;/span&gt;&lt;/p&gt;

receivable are stated at the net amount expected to be collected. Amounts are ordinarily due between 30 and 90 days after the issuance of the invoice. We are exposed to credit losses primarily on our accounts receivable and contract assets related to our 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 was immaterial. Expected credit losses are written off in the period in which the financial asset is no longer collectible.&lt;/span&gt;&lt;/p&gt;

Company grants credit to its customers, generally, without collateral, under normal payment terms (typically 30 to 90 days after invoicing).
Generally, invoicing occurs after the services are performed or control of the product has transferred to the customer. Accounts receivable

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;

instruments that potentially subject the Company to credit risk consist principally of trade accounts receivable, short term investments
and cash equivalents. The Company believes that its credit risk is limited because the Company&#x2019;s current contracts are with entities
with a reliable payment history. The Company invests its excess cash in a money market fund and short term held-to maturity investments
and does not believe that it is exposed to any significant risks related to its cash accounts, money market fund, or held-to maturity
investments. Cash is also maintained at foreign financial institutions. Cash in foreign financial institutions as of July 31, 2023 was
immaterial.&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 0pt 0pt 0; 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;

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. Our estimates of variable consideration and determination of
whether to include such amounts in the transaction price are based largely on our 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 July 31, 2023 or 2022. The Company presents shipping and handling costs, that occur after control of the promised goods or services
transfer to the customer, as fulfillment costs in costs of goods sold 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 0pt 0pt 0; 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;/span&gt;&lt;/p&gt;

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 0pt 0pt 0; 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 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&#x2019;s share of the
costs is recorded as product development expense. The Company reports its disaggregation of revenue by contract type since this method
best represents the Company&#x2019;s business. For the three-month periods ended July 31, 2023 and 2022, 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="margin: 0; text-align: justify"&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;/p&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 0"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

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. 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 Topic 842, &#x201c;Leases&#x201d;. 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 Revenue 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. Where the Company use 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 sales 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 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 2023 and determined that it is more likely than not that no goodwill impairment existed
as of April 30, 2023.&lt;/span&gt;&lt;/p&gt;

taxes are accounted for under ACS 740 utilizing the asset and liability method. Deferred tax assets and liabilities are recognized for
the future tax consequences 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;

Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained upon examination.
Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition
or measurement are reflected in the period in which the change in judgment occurs. The Company records interest related to unrecognized
tax benefits in interest expense and penalties in selling, general, and administrative expenses, to the extent incurred. Refer to Note
15 for additional disclosure.&lt;/span&gt;&lt;/p&gt;

June 2016, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued ASU No. 2016-13, &#x201c;&lt;i&gt;Financial Instruments &lt;/i&gt;-
&lt;i&gt;Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.&#x201d; &lt;/i&gt;This amendment replaces the incurred
loss impairment methodology in current GAAP with a methodology that reflects expected credit losses on instruments within its scope,
including trade receivables. This update is intended to provide financial statement users with more decision-useful information about
the expected credit losses. In November 2019, the FASB issued No. 2019-10, &lt;i&gt;Financial Instruments&#x2014;Credit Losses (Topic 326),
Derivatives and Hedging (Topic 815), and Leases (Topic 842)&lt;/i&gt;, which deferred the effective date of ASU 2016-13 for Smaller Reporting
Companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company has evaluated
the impact on its consolidated financial statements from the adoption of ASU 2016-13, and has determined there is no material impact.&lt;/span&gt;&lt;/p&gt;

asset 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;

ASC 842 allows a company an accounting policy election to recognize lease payments within the Consolidated
Statement of Operations on a straight-line basis if the lease term is equal to or less than 12 months and not recognize a right-of use
asset and lease liability. The accounting policy election is made on the commencement date of the lease. The Company has chosen this
election for the Houston lease and classified it as a short-term lease.&lt;/span&gt;&lt;/p&gt;

not previously employees of the Company (or following such individuals&#x2019; bona fide period of non-employment with the Company), as

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 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 three months ended July 31,
2023 and 2022.&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;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0pt 0pt 0; 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;td style="text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;Unadjusted quoted prices in active markets for identical assets
or liabilities that the Company has the ability to access at the measurement date.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;

&lt;tr style="vertical-align: top"&gt;

  &lt;td style="text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"&gt;Inputs other than quoted prices in active markets that are
observable for the asset or liability, either directly or indirectly.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;

Company&#x2019;s financial instruments that are not re-measured at fair value include cash, cash equivalents, restricted cash, accounts

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_90F_eus-gaap--IncomeTaxExaminationPenaltiesAndInterestAccrued_iI_uEuro_c20220430__us-gaap--IncomeTaxAuthorityNameAxis__us-gaap--TaxAuthoritySpainMember_z035oGWHi5Db" title="Income tax penalties"&gt;279,870&lt;/span&gt; or approximately

time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability

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

account 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 has 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). At July 31, 2023, 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;

June 2023, the Company adopted a Section 382 Tax Benefits Preservation Plan (the &#x201c;Tax Benefits Preservation Plan&#x201d; or 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_900_ecustom--BusinessAcquisitionOutstandingCommonStockOwnershipPercentage_iI_dp_uPure_c20230630_zee5gknDmhD" title="Acquisition outstanding common stock ownership percentage"&gt;4.99&lt;/span&gt;% or more of the outstanding

statements and deemed to be de minimis, and accordingly was not recorded to the financial statements.&lt;/span&gt;&lt;/p&gt;
