(1) Background, Basis of Presentation and Liquidity (a) Background Ocean Power Technologies, Inc. (“OPT,” “we,” “our,” or “the Company”) is a Maritime Domain Awareness (MDA) company specializing in innovative intelligent maritime solutions. These solutions include a variety of “as a service” systems, including Data as a Service (DaaS), Robotics as a Service (RaaS), and Power as a Service (PaaS). These systems consist of a variety of platforms including the PowerBuoy®, our persistent sensor and power solution, the WAM-V® (Wave Adaptive Modular Vessel), our autonomous unmanned surface vehicle, and Merrows™, our user interface and command and control (C2) system that integrates multiple sensor feeds using software and hardware and enables artificial intelligence and machine learning (AI/ML) integration. We design, manufacture, deploy, and operate these systems for defense, security, subsea infrastructure, offshore oil and gas, offshore energy, marine research, and communication markets. We operate primarily through a combination of direct sales and leases, strategic partnerships, and long-term service agreements. Our business model emphasizes capital-light deployments, recurring revenue from service and maintenance contracts, and high-margin technology sales and leases. We serve a global customer base, including the U.S. and allied defense agencies, offshore energy operators, and commercial interests. The common thread across these markets is the growing need for a persistent, autonomous, and sustainable offshore presence, a need we are uniquely positioned to fulfill. The Company holds numerous patents and leverages decades of research including control systems, energy storage, and marine integration. Our headquarters and assembly operations are located in New Jersey, and we maintain an additional manufacturing and robotics development facility in Richmond, CA. In addition, the Company maintains an office at the Association for Uncrewed Vehicle Systems International (AUVSI) headquarters in Washington, D.C., which serves to strengthen our strategic position in the fast-growing uncrewed systems market. OPT is committed to enabling a smarter, safer ocean economy through innovation in ocean intelligence and power. As we look forward, our strategic priorities include expanding our customer and geographic base, accelerating technology adoption, enhancing recurring revenue, and driving margin growth through platform scalability and supply chain efficiencies. We were incorporated under the laws of the State of New Jersey in April 1984 and began commercial operations in 1994. On April 23, 2007, we reincorporated in Delaware. (b) Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and for interim financial information in accordance with the Securities and Exchange Commission (“SEC”), instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The interim operating results are not necessarily indicative of the results for a full year or for any other interim period. Further information on potential factors that could affect the Company’s financial results can be found in the Company’s Annual Report on Form 10-K for the year ended April 30, 2025, as filed with the SEC and elsewhere in subsequent Exchange Act filings, including this Form 10-Q. (c) Liquidity During the three months ended July 31, 2025, the Company incurred a net loss of approximately $7.4 million and used cash in operations of approximately $5.6 million. The Company’s future results of operations involve significant risks and uncertainties. Factors that could affect the Company’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. The Company believes cash on hand and forecasted operating results will provide sufficient liquidity to meet its obligation for at least the next 12 months. In the event operating results are not sufficient the Company will need to seek additional financing. There can be no assurance that the Company will be able to raise additional capital on favorable terms, or at all, if needed.

(2) Summary of Significant Accounting Policies (a) Consolidation The accompanying consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries, Marine Advanced Robotics Inc. (CA), referred to herein as MAR,), Oregon Wave Energy Partners I LLC (DE), and ReedSport OPT WavePark, LLC (OR). Ocean Power Technologies Ltd. in the United Kingdom was dissolved on April 22, 2025. ReedSport OPT WavePark, LLC (OR) and Oregon Wave Energy Partners I, LLC (DE) were dissolved during the first quarter of fiscal 2024. All significant intercompany balances and transactions have been eliminated in consolidation. (b) Use of Estimates The preparation of the consolidated financial statements requires management of the Company to make several estimates and assumptions relating to the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the period. Significant items subject to such estimates and assumptions include, among other items, stock-based compensation based on the likelihood of meeting performance obligations, over time revenue recognition, valuation consideration related to business combinations, including contingent consideration based on actual and projected revenues, in addition to discount rates and present values, and other assumptions and estimates used to evaluate the recoverability of long-lived assets, goodwill and other intangible assets. Actual results could differ from those estimates. (c) Cash, Cash Equivalents, Restricted Cash and Security Agreements Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased, to be cash equivalents. The Company invests excess cash in a money market account. The Company had cash and cash equivalents of approximately $10.0 million and $6.9 million as of July 31, 2025 and April 30, 2025, respectively. Restricted Cash and Security Agreements The Company has a letter of credit agreement with Santander Bank, N.A. (“Santander”). Cash of $154,000 is on deposit at Santander and serves as security for a letter of credit issued by Santander for the lease of warehouse/office space in Monroe Township, New Jersey. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets that total to the same amounts shown in the Consolidated Statements of Cash Flows.

Items remain in inventory until they are shipped to the customer, at which time the costs are transferred on a FIFO basis to cost of revenues, or moved to leased assets as applicable, following the matching principle where costs and revenues are recognized in the same period. The Company has three classes of inventory; raw materials, work in process, and finished goods. (e) Accounts Receivable Accounts receivable are stated at the net amount expected to be collected. Amounts are usually due between 30 and 90 days after the invoice issuance. The Company is exposed to credit losses primarily on accounts receivable and contract assets related to sales to customers. If applicable, an allowance for credit losses is established to provide for the expected lifetime credit losses by evaluating factors such as customer creditworthiness, historical payment and loss experiences, current economic conditions (including geographic and political risk), and the age and status of outstanding receivables. Based on these factors, management has determined the allowance for credit losses was approximately $100,000 at both July 31, 2025 and April 30, 2025. Expected credit losses are written off in the period in which the financial assets are no longer collectible. The Company grants credit to its customers, generally, without collateral, under normal payment. Generally, invoicing occurs after the services are performed or control of the product has transferred to the customer. Accounts receivable represent an unconditional right to consideration arising from the Company’s performance under contracts with customers. (f) Property and Equipment, net Property 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 3 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.

(h) Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist principally of trade accounts receivable and cash equivalents. The Company believes that its credit risk is limited because the Company’s current contracts are with entities with a reliable payment history. The Company invests its excess cash in a money market fund and does not believe that it is exposed to any significant risks related to its cash accounts or money market funds. For the three months ended July 31, 2025 and 2024, the Company had four and two customers, respectively, whose revenues accounted for at least 10% of the Company’s consolidated revenues. These revenues accounted for approximately <span id="xdx_90C_eus-gaap--ConcentrationRiskPercentage1_pid_dp_uPure_c20250501__20250731__us-gaap--ConcentrationRiskByBenchmarkAxis__us-gaap--SalesRevenueNetMember__us-gaap--ConcentrationRiskByTypeAxis__us-gaap--CustomerConcentrationRiskMember__srt--MajorCustomersAxis__custom--FourCustomersMember_zwSY3TorApT5" title="Concentration risk percentage">89% and <span id="xdx_908_eus-gaap--ConcentrationRiskPercentage1_pid_dp_uPure_c20240501__20240731__us-gaap--ConcentrationRiskByBenchmarkAxis__us-gaap--SalesRevenueNetMember__us-gaap--ConcentrationRiskByTypeAxis__us-gaap--CustomerConcentrationRiskMember__srt--MajorCustomersAxis__custom--TwoCustomersMember_zqyx0bjwmRZ7" title="Concentration risk percentage">84% of the Company’s total revenues for the respective periods.

As part of that contract, we granted extended payment terms that are not typical for the Company, which increases our credit exposure. We continue to monitor this receivable closely, and while we have not recorded an allowance because we believe collectability is probable, we acknowledge that these terms carry additional risk if the customer’s financial condition changes. (i) Share-Based Compensation Costs resulting from all share-based payment transactions are recognized in the consolidated financial statements at their fair values. The aggregate share-based compensation expense recorded in the Consolidated Statements of Operations for the three months ended July 31, 2025 and 2024 was approximately $2.4 million and $0.3 million, respectively. The Company’s policy is to account for forfeitures of share-based compensation as they occur. Additionally, upon vesting of Restricted Stock Units (“RSU”) that were granted to an employee, the employee is given the option to either pay the taxes themselves, or have enough shares of their RSU award withheld by the Company to cover the taxes incurred by the employee. In the event the employee elects to surrender shares to cover the tax implication, the Company maintains those shares in the Company’s treasury stock account. Shares held in the Company’s treasury stock account are not available for future RSU grants. (j) Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification 606 (ASC 606) for contracts with customers and Accounting Standards Codification 842 (ASC 842) for leasing arrangements. In relation to ASC 606, which states that a performance obligation is the unit of account for revenue recognition, the Company assesses the goods or services promised in a contract with a customer and identifies as a performance obligation as either: a) a good or service (or a bundle of goods or services) that is distinct; or b) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. A contract may contain a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the Company allocates the contracted transaction price to each performance obligation based upon the relative standalone selling price, which represents the price the Company would sell a promised good or service separately to a customer. The Company determines the standalone selling price based upon the facts and circumstances of each obligated good or service. When no observable standalone selling price is available, the standalone selling price is generally estimated based upon the Company’s forecast of the total cost to satisfy the performance obligation plus an appropriate profit margin. The nature of the Company’s contracts may give rise to several types of variable consideration, including unpriced change orders, liquidated damages and penalties. Variable consideration can also arise from modifications to the scope of services. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on the assessment of legal enforceability, performance, and any other information (historical, current, and forecasted) that is reasonably available to us. There was no variable consideration as of April 30, 2025 or 2024. The Company presents shipping and handling costs, that occur after control of the promised goods or services transfer to the customer, as fulfillment costs in costs of goods sold and regular shipping and handling activities charged to operating expenses. The Company recognizes revenue when or as it satisfies a performance obligation by transferring a good or service to a customer, either (1) at a point in time or (2) over time. A good or service is transferred when or as the customer obtains control (e.g., upon shipment, upon delivery, as services are rendered, or upon completion of service), including when performance obligations are satisfied in a bill-and-hold arrangement. 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’s services. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the services to be provided. For the Company, the input method using costs or labor hours incurred best represents the measure of progress against the performance obligations incorporated within the contractual agreements. If estimated total costs on any contract project a loss, the Company charges the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, change orders, claims, anticipated losses, and others are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. These loss projections are re-assessed for each subsequent reporting period until the project is complete. Such revisions could occur at any time and the effects may be material. During the three month period ended July 31, 2025, the Company recognized approximately $1.0 million in revenue related to performance obligations satisfied at a point in time and approximately $0.2 million in revenue related to performance obligations satisfied over time. During the three month period ended July 31, 2024, the Company recognized approximately $1.2 million in revenue related to performance obligations satisfied at a point in time and approximately $0.1 million in revenue related to performance obligations satisfied over time. The Company’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. The Company has two types of fixed-price contracts, firm fixed-price and cost-sharing. Under firm fixed-price contracts, the Company receives an agreed-upon amount for providing products and services specified in the contract, and a profit or loss is recognized depending on whether actual costs are more or less than the agreed-upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the customer is only intended to fund a portion of the costs on a specific project. Under cost-sharing contracts, an amount corresponding to the revenue is recorded in cost of revenue, resulting in gross profit on these contracts of zero. The Company reports its disaggregation of revenue by contract type since this method best represents the Company’s business. For each of the three month periods ended July 31, 2025 and 2024, the majority of the Company’s contracts were classified as firm fixed-price and the remainder were cost-sharing. The Company’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’s accounts receivable balance is made up entirely of customer contract-related balances. The Company’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, “Leases”. At inception of a contract for those classified under ASC 842, the Company classifies leases as either operating or financing in accordance with the authoritative accounting guidance contained within ASC 842. If the direct financing or sales-type classification criteria are met, then the lease is accounted for as a finance lease. All others are treated as operating leases. The Company recognizes revenue from operating lease arrangements generally on a straight-line basis over the lease term, or as agreed upon in-use days are utilized, which is presented in Revenues in the Consolidated Statement of Operations. The Company also enters into lease arrangements for its PowerBuoys® and Wave Adaptive Modular Vessels (“WAM-V®”) 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®, WAM-V®, 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® at some point during and/or at the end of the lease term. Existing 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. The Company has elected to record taxes collected from customers on a net basis and does not include tax amounts in revenue or costs of revenue. The table below represents the total revenue recognized under ASC 606 and ASC 842 for the three months ended July 31, 2025 and 2024.

Share purchase rights, which include a contingency, are not included in the calculation until the contingency is resolved. (l) Intangibles, net Intangible assets acquired in a business combination are recognized separately from goodwill and are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Intangible assets, including patents, are amortized over the estimated useful life of the asset on a basis that approximates the pattern of economic benefit. The patents, trade name and customer relationship intangibles are being amortized over <span id="xdx_903_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_iI_dtY_c20250731__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--PatentsMember_zXIvcYkkhoS6" title="Intangible asset estimated lives">20, <span id="xdx_90F_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_iI_dtY_c20250731__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--TradeNamesMember_zrIDjVHx8B94" title="Intangible asset estimated lives">12 and <span id="xdx_90E_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_iI_dtY_c20250731__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--CustomerRelationshipsMember_ziYYu1J80fXh" title="Intangible asset estimated lives">10 years respectively, which is consistent with the estimated pattern of economic benefit of the assets. The trademark is not subject to amortization. Intangible assets are reviewed for impairment if indicators of potential impairment exist. There were no indications of potential impairment of intangible assets for either the three months ended July 31, 2025 or 2024. (m) Goodwill Goodwill 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. Management performed its annual qualitative assessment in fiscal year 2025 and determined that it is more likely than not that no goodwill impairment existed as of April 30, 2025. There were no indications of potential impairment of goodwill identified for the three months ended July 31, 2025 and 2024. When the Company uses a qualitative analysis, it considers factors that include historical financial performance, macroeconomic and industry conditions, and the legal and regulatory environment. If the qualitative assessment indicates that it is more likely than not that an impairment exists, then a quantitative assessment is also performed. The quantitative assessment requires an analysis of several estimates including future cash flows or income consistent with management’s strategic business plans, annual revenue growth rates and the selection of assumptions underlying a discount rate (weighted average cost of capital) based on market data available at the time to determine the fair value of the Company. If the fair value is less than the carrying amounts, an impairment charge for the difference is recorded. (n) Income Taxes The 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. In order to monetize their attributes, the Company has historically sold the Net Operating Losses (NOL’s) generated in New Jersey. The Company has elected to recognize the gain on the sale as a component of tax expense at the time of the sale. Prior to the time of sale, the Company has elected to not factor the expected sales when assessing the realizability of the related deferred tax assets. (o) Accumulated Other Comprehensive Loss The functional currency for the Company’s foreign operations is the applicable local currency. The translation from the applicable foreign currencies to U.S. dollars is performed for balance sheet accounts using the exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. The unrealized gains or losses resulting from such translation are included in Accumulated Other Comprehensive Loss within Shareholders’ Equity. For each of the three months ended July 31, 2025 and 2024, there were no amounts recorded to other comprehensive loss due to limited foreign operations. (p) Warranty The Company does not include a right of return on its products other than rights related to standard warranty provisions that permit repair or replacement of defective goods. Warranty expense incurred to date has not been material. (q) Product Development Costs related to product development activities by the Company are expensed as incurred. The Company had approximately $0.6 million and $0.5 million in product development expense for the three months ended July 31, 2025 and 2024, respectively. (r) Derivative Financial Instruments The Company evaluates all its financial instruments to determine if such instruments contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the statement of operations each period. (s) Recently Issued Accounting Standards In the interim period ended July 31, 2025, the following FASB issued Accounting Standards Updates (ASUs) that may be relevant to the Company’s operations and financial reporting. We are currently evaluating the potential impact of these ASUs and adopting them when applicable based on their effective dates. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which improves the transparency of income tax disclosures by requiring companies to (1) disclose consistent categories and greater disaggregation of information in the effective rate reconciliation and (2) provide information on income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, although early adoption is permitted. The guidance should be applied on a prospective basis with the option to apply the standard retrospectively. We are currently evaluating the impact of adopting this ASU 2023-09 on our consolidated financial statements and disclosures for the annual period ending April 30, 2026. In November 2024, the FASB issued ASU No. 2024-3, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU improves the disclosures about a public business entity’s expenses and addresses requests from investors for more detailed information about the types of expenses in commonly presented expense captions. The new guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating what the potential impact of adopting this ASU 2024-03 could have on our consolidated financial statements and disclosures In July 2025, the FASB issued Accounting Standards Update 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). ASU 2025-05 provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, Revenue from Contracts with Customers. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim reporting periods in those years. Entities that elect the practical expedient and, if applicable, make the accounting policy election are required to apply the amendments prospectively. We are currently evaluating the potential impact of adopting ASU 2025-05 on our consolidated financial statements and disclosures.

(a) Consolidation The accompanying consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries, Marine Advanced Robotics Inc. (CA), referred to herein as MAR,), Oregon Wave Energy Partners I LLC (DE), and ReedSport OPT WavePark, LLC (OR). Ocean Power Technologies Ltd. in the United Kingdom was dissolved on April 22, 2025. ReedSport OPT WavePark, LLC (OR) and Oregon Wave Energy Partners I, LLC (DE) were dissolved during the first quarter of fiscal 2024. All significant intercompany balances and transactions have been eliminated in consolidation.

(b) Use of Estimates The preparation of the consolidated financial statements requires management of the Company to make several estimates and assumptions relating to the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the period. Significant items subject to such estimates and assumptions include, among other items, stock-based compensation based on the likelihood of meeting performance obligations, over time revenue recognition, valuation consideration related to business combinations, including contingent consideration based on actual and projected revenues, in addition to discount rates and present values, and other assumptions and estimates used to evaluate the recoverability of long-lived assets, goodwill and other intangible assets. Actual results could differ from those estimates.

(c) Cash, Cash Equivalents, Restricted Cash and Security Agreements Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased, to be cash equivalents. The Company invests excess cash in a money market account. The Company had cash and cash equivalents of approximately $10.0 million and $6.9 million as of July 31, 2025 and April 30, 2025, respectively. Restricted Cash and Security Agreements The Company has a letter of credit agreement with Santander Bank, N.A. (“Santander”). Cash of $154,000 is on deposit at Santander and serves as security for a letter of credit issued by Santander for the lease of warehouse/office space in Monroe Township, New Jersey.

(d) Inventory In accordance with Accounting Standards Codification 330 (ASC 330), inventory is stated at the lower of cost or net realizable value applicable to goods on hand. Items remain in inventory until they are shipped to the customer, at which time the costs are transferred on a FIFO basis to cost of revenues, or moved to leased assets as applicable, following the matching principle where costs and revenues are recognized in the same period. The Company has three classes of inventory; raw materials, work in process, and finished goods.

(e) Accounts Receivable Accounts receivable are stated at the net amount expected to be collected. Amounts are usually due between 30 and 90 days after the invoice issuance. The Company is exposed to credit losses primarily on accounts receivable and contract assets related to sales to customers. If applicable, an allowance for credit losses is established to provide for the expected lifetime credit losses by evaluating factors such as customer creditworthiness, historical payment and loss experiences, current economic conditions (including geographic and political risk), and the age and status of outstanding receivables. Based on these factors, management has determined the allowance for credit losses was approximately $100,000 at both July 31, 2025 and April 30, 2025. Expected credit losses are written off in the period in which the financial assets are no longer collectible. The Company grants credit to its customers, generally, without collateral, under normal payment. Generally, invoicing occurs after the services are performed or control of the product has transferred to the customer. Accounts receivable represent an unconditional right to consideration arising from the Company’s performance under contracts with customers.

(f) Property and Equipment, net Property 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 3 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.

(g) Foreign Exchange Gains and Losses Transactions denominated in a foreign currency may result in realized and unrealized foreign exchange gains or losses from exchange rate fluctuations, which, if applicable, are included in “Foreign exchange gain” in the accompanying Consolidated Statements of Operations.

(h) Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist principally of trade accounts receivable and cash equivalents. The Company believes that its credit risk is limited because the Company’s current contracts are with entities with a reliable payment history. The Company invests its excess cash in a money market fund and does not believe that it is exposed to any significant risks related to its cash accounts or money market funds.

(i) Share-Based Compensation Costs resulting from all share-based payment transactions are recognized in the consolidated financial statements at their fair values. The aggregate share-based compensation expense recorded in the Consolidated Statements of Operations for the three months ended July 31, 2025 and 2024 was approximately $2.4 million and $0.3 million, respectively. The Company’s policy is to account for forfeitures of share-based compensation as they occur. Additionally, upon vesting of Restricted Stock Units (“RSU”) that were granted to an employee, the employee is given the option to either pay the taxes themselves, or have enough shares of their RSU award withheld by the Company to cover the taxes incurred by the employee. In the event the employee elects to surrender shares to cover the tax implication, the Company maintains those shares in the Company’s treasury stock account. Shares held in the Company’s treasury stock account are not available for future RSU grants.

(j) Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification 606 (ASC 606) for contracts with customers and Accounting Standards Codification 842 (ASC 842) for leasing arrangements. In relation to ASC 606, which states that a performance obligation is the unit of account for revenue recognition, the Company assesses the goods or services promised in a contract with a customer and identifies as a performance obligation as either: a) a good or service (or a bundle of goods or services) that is distinct; or b) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. A contract may contain a single performance obligation or multiple performance obligations. For contracts with multiple performance obligations, the Company allocates the contracted transaction price to each performance obligation based upon the relative standalone selling price, which represents the price the Company would sell a promised good or service separately to a customer. The Company determines the standalone selling price based upon the facts and circumstances of each obligated good or service. When no observable standalone selling price is available, the standalone selling price is generally estimated based upon the Company’s forecast of the total cost to satisfy the performance obligation plus an appropriate profit margin. The nature of the Company’s contracts may give rise to several types of variable consideration, including unpriced change orders, liquidated damages and penalties. Variable consideration can also arise from modifications to the scope of services. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur once the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include such amounts in the transaction price are based largely on the assessment of legal enforceability, performance, and any other information (historical, current, and forecasted) that is reasonably available to us. There was no variable consideration as of April 30, 2025 or 2024. The Company presents shipping and handling costs, that occur after control of the promised goods or services transfer to the customer, as fulfillment costs in costs of goods sold and regular shipping and handling activities charged to operating expenses. The Company recognizes revenue when or as it satisfies a performance obligation by transferring a good or service to a customer, either (1) at a point in time or (2) over time. A good or service is transferred when or as the customer obtains control (e.g., upon shipment, upon delivery, as services are rendered, or upon completion of service), including when performance obligations are satisfied in a bill-and-hold arrangement. 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’s services. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the services to be provided. For the Company, the input method using costs or labor hours incurred best represents the measure of progress against the performance obligations incorporated within the contractual agreements. If estimated total costs on any contract project a loss, the Company charges the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, change orders, claims, anticipated losses, and others are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. These loss projections are re-assessed for each subsequent reporting period until the project is complete. Such revisions could occur at any time and the effects may be material. During the three month period ended July 31, 2025, the Company recognized approximately $1.0 million in revenue related to performance obligations satisfied at a point in time and approximately $0.2 million in revenue related to performance obligations satisfied over time. During the three month period ended July 31, 2024, the Company recognized approximately $1.2 million in revenue related to performance obligations satisfied at a point in time and approximately $0.1 million in revenue related to performance obligations satisfied over time. The Company’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. The Company has two types of fixed-price contracts, firm fixed-price and cost-sharing. Under firm fixed-price contracts, the Company receives an agreed-upon amount for providing products and services specified in the contract, and a profit or loss is recognized depending on whether actual costs are more or less than the agreed-upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the customer is only intended to fund a portion of the costs on a specific project. Under cost-sharing contracts, an amount corresponding to the revenue is recorded in cost of revenue, resulting in gross profit on these contracts of zero. The Company reports its disaggregation of revenue by contract type since this method best represents the Company’s business. For each of the three month periods ended July 31, 2025 and 2024, the majority of the Company’s contracts were classified as firm fixed-price and the remainder were cost-sharing. The Company’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’s accounts receivable balance is made up entirely of customer contract-related balances. The Company’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, “Leases”. At inception of a contract for those classified under ASC 842, the Company classifies leases as either operating or financing in accordance with the authoritative accounting guidance contained within ASC 842. If the direct financing or sales-type classification criteria are met, then the lease is accounted for as a finance lease. All others are treated as operating leases. The Company recognizes revenue from operating lease arrangements generally on a straight-line basis over the lease term, or as agreed upon in-use days are utilized, which is presented in Revenues in the Consolidated Statement of Operations. The Company also enters into lease arrangements for its PowerBuoys® and Wave Adaptive Modular Vessels (“WAM-V®”) 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®, WAM-V®, 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® at some point during and/or at the end of the lease term. Existing 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. The Company has elected to record taxes collected from customers on a net basis and does not include tax amounts in revenue or costs of revenue.

(k) Net Loss per Common Share Basic and diluted net loss per common share for all periods presented is computed by dividing net loss by the weighted average number of shares of common stock and common stock equivalents outstanding during the period. Due to the Company’s net losses, potentially dilutive securities, consisting of options to purchase shares of common stock, and unvested RSUs issued to employees and non-employee directors, were excluded from the diluted loss per share calculation due to their anti-dilutive effect. In computing diluted net loss per common share on the Consolidated Statement of Operations, options to purchase shares of common stock and unvested RSUs issued to employees and non-employee directors, totaling <span id="xdx_905_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_c20250501__20250731_z9CdjvL72pLe" title="Antidilutive securities excluded from computation of diluted net loss per share">22,285,129 and <span id="xdx_90E_eus-gaap--AntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareAmount_c20240501__20240731_zS8hTOem59j3" title="Antidilutive securities excluded from computation of diluted net loss per share">6,259,956 for the three months ended July 31, 2025 and 2024, respectively, were excluded from each of the computations as the effect would have been anti-dilutive due to the net loss for the periods.

(l) Intangibles, net Intangible assets acquired in a business combination are recognized separately from goodwill and are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Intangible assets, including patents, are amortized over the estimated useful life of the asset on a basis that approximates the pattern of economic benefit. The patents, trade name and customer relationship intangibles are being amortized over <span id="xdx_903_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_iI_dtY_c20250731__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--PatentsMember_zXIvcYkkhoS6" title="Intangible asset estimated lives">20, <span id="xdx_90F_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_iI_dtY_c20250731__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--TradeNamesMember_zrIDjVHx8B94" title="Intangible asset estimated lives">12 and <span id="xdx_90E_eus-gaap--FiniteLivedIntangibleAssetUsefulLife_iI_dtY_c20250731__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--CustomerRelationshipsMember_ziYYu1J80fXh" title="Intangible asset estimated lives">10 years respectively, which is consistent with the estimated pattern of economic benefit of the assets. The trademark is not subject to amortization. Intangible assets are reviewed for impairment if indicators of potential impairment exist. There were no indications of potential impairment of intangible assets for either the three months ended July 31, 2025 or 2024.

(m) Goodwill Goodwill 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. Management performed its annual qualitative assessment in fiscal year 2025 and determined that it is more likely than not that no goodwill impairment existed as of April 30, 2025. There were no indications of potential impairment of goodwill identified for the three months ended July 31, 2025 and 2024. When the Company uses a qualitative analysis, it considers factors that include historical financial performance, macroeconomic and industry conditions, and the legal and regulatory environment. If the qualitative assessment indicates that it is more likely than not that an impairment exists, then a quantitative assessment is also performed. The quantitative assessment requires an analysis of several estimates including future cash flows or income consistent with management’s strategic business plans, annual revenue growth rates and the selection of assumptions underlying a discount rate (weighted average cost of capital) based on market data available at the time to determine the fair value of the Company. If the fair value is less than the carrying amounts, an impairment charge for the difference is recorded.

(n) Income Taxes The 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. In order to monetize their attributes, the Company has historically sold the Net Operating Losses (NOL’s) generated in New Jersey. The Company has elected to recognize the gain on the sale as a component of tax expense at the time of the sale. Prior to the time of sale, the Company has elected to not factor the expected sales when assessing the realizability of the related deferred tax assets.

(o) Accumulated Other Comprehensive Loss The functional currency for the Company’s foreign operations is the applicable local currency. The translation from the applicable foreign currencies to U.S. dollars is performed for balance sheet accounts using the exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. The unrealized gains or losses resulting from such translation are included in Accumulated Other Comprehensive Loss within Shareholders’ Equity. For each of the three months ended July 31, 2025 and 2024, there were no amounts recorded to other comprehensive loss due to limited foreign operations. (p) Warranty The Company does not include a right of return on its products other than rights related to standard warranty provisions that permit repair or replacement of defective goods. Warranty expense incurred to date has not been material.

(q) Product Development Costs related to product development activities by the Company are expensed as incurred. The Company had approximately $0.6 million and $0.5 million in product development expense for the three months ended July 31, 2025 and 2024, respectively.

(r) Derivative Financial Instruments The Company evaluates all its financial instruments to determine if such instruments contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the statement of operations each period.

(s) Recently Issued Accounting Standards In the interim period ended July 31, 2025, the following FASB issued Accounting Standards Updates (ASUs) that may be relevant to the Company’s operations and financial reporting. We are currently evaluating the potential impact of these ASUs and adopting them when applicable based on their effective dates. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which improves the transparency of income tax disclosures by requiring companies to (1) disclose consistent categories and greater disaggregation of information in the effective rate reconciliation and (2) provide information on income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, although early adoption is permitted. The guidance should be applied on a prospective basis with the option to apply the standard retrospectively. We are currently evaluating the impact of adopting this ASU 2023-09 on our consolidated financial statements and disclosures for the annual period ending April 30, 2026. In November 2024, the FASB issued ASU No. 2024-3, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU improves the disclosures about a public business entity’s expenses and addresses requests from investors for more detailed information about the types of expenses in commonly presented expense captions. The new guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating what the potential impact of adopting this ASU 2024-03 could have on our consolidated financial statements and disclosures In July 2025, the FASB issued Accounting Standards Update 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). ASU 2025-05 provides a practical expedient that all entities can use when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606, Revenue from Contracts with Customers. Under this practical expedient, an entity is allowed to assume that the current conditions it has applied in determining credit loss allowances for current accounts receivable and current contract assets remain unchanged for the remaining life of those assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim reporting periods in those years. Entities that elect the practical expedient and, if applicable, make the accounting policy election are required to apply the amendments prospectively. We are currently evaluating the potential impact of adopting ASU 2025-05 on our consolidated financial statements and disclosures.

(9) Leases Lessor Information As of July 31, 2025 and April 30, 2025, the Company had three WAM-V’s leased to customers which have been classified as operating leases per accounting guidance contained within ASC Topic 842, “Leases”, respectively. The remaining term on these operating leases is less than 2 years. Lessee Information Right-of-use assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. When the implicit rate of the lease is not provided or cannot be determined, the Company uses the incremental borrowing rate based on the information available at the effective date to determine the present value of future payments. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The renewal options have not been included in the lease term as they are not reasonably certain of exercise. The Company’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. The Company has a lease for its facility located in Monroe Township, New Jersey that is used as warehouse/production space and the Company’s principal offices and corporate headquarters. In February 2024, the Company extended the lease for its main headquarters in Monroe, NJ to April 30, 2026 and it was executed and recorded as an additional right of use asset and liability. The lease is classified as an operating lease and is included in right-of-use assets, right-of-use liabilities – current, and right-of-use liabilities- long-term on the Company’s Consolidated Balance Sheets. The Company also has a lease for office space located in Richmond, California. This lease commenced in April of 2023 and will continue for 62 months. The lease is classified as an operating lease and is included in right-of-use assets, right-of-use liabilities- current and right-of-use liabilities- long-term on the Company’s Consolidated Balance Sheets. The Company also has a lease for warehouse space located in Richmond, California. The lease commenced in June of 2025 and will continue for 24 months.

Stock Options The Company estimates the fair value of each stock option award granted with service-based vesting requirements, using the Black-Scholes option pricing model, assuming no dividends, and using weighted average valuation assumptions. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant commensurate with the expected life of the award. The expected life (estimated period of time outstanding) of the stock options granted was estimated using the “simplified” method as permitted by the SEC’s Staff Accounting Bulletin No. 110, Share-Based Payment. Expected volatility is based on the Company’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, 2025 and 2024, respectively. A summary of stock options under the stock incentive plans is detailed in the following table.

(12) Fair Value Measurements ASC Topic 820, “Fair Value Measurements” 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 convertible debt has a conversion feature was determined to be an embedded derivative that requires bifurcation and separate accounting from the host instrument. At inception, the fair value of the derivative liability was approximately $699,000. The sale of additional equity under new facilities could result in dilution to our shareholders. If additional funds are raised through the issuance of debt securities or preferred stock, these securities could have rights senior to those associated with our common stock and could contain covenants that would restrict our operations. The Company cannot be certain that additional equity and/or debt financing will be available to the Company as needed on acceptable terms, or at all. If we are unable to obtain required financing when needed, we may be required to reduce the scope of our operations, including our planned incremental product development and marketing efforts, which could materially and adversely affect our financial condition and operating results. If we are unable to secure additional financing, we may be forced to cease our operations.

(14) Commitments and Contingencies Litigation with Paragon Technologies, Inc. On October 10, 2023, Paragon Technologies, Inc. filed a complaint in the Court of Chancery of the State of Delaware against the Company, and the members of its Board of Directors, claiming certain breaches of their fiduciary duties. The complaint sought only injunctive relief against the Company, and not monetary damages, and therefore the financial exposure derived therein was limited to applicable legal fees and costs at that stage, which was material to FY’ 24. The hearing on the initial complaint was held and on November 30, 2023, the Court ruled in favor of the Company and denied Paragon’s motion for injunctive relief. On February 28, 2024, the Company successfully finalized its 2023 annual meeting of stockholders in spite of Paragon’s repeated attempts to contest the meeting. In an August 12, 2024 Press Release and its Form 10-Q report for the second quarter of 2024, Paragon announced that it was no longer pursuing litigation against the Company. Pursuant to a Court order dated January 9, 2025, Paragon was required “to file a status report within 30 days. Otherwise, the case will be dismissed under Rule 41(e).” Because Paragon did not file a status report by February 10, 2025, the Company anticipates that the Court will dismiss the case, with prejudice, due to Paragon’s failure to prosecute. Section 220 Demand In February 2025, the Company received a shareholder demand under Section 220 of the General Corporation Law of the State of Delaware for inspection of certain books and records relating to prior equity grants made to officers and directors under the 2015 Plan in January 2023, February 2024 and January 2025. The Company has provided the Plaintiff documents fully responsive to the Demand. The Company is reviewing and considering the demand and engaging with counsel for the shareholder but has not recorded any material liability for these matters as of July 31, 2025 or April 30, 2025 as it cannot estimate the ultimate outcome at this time. General Legal Matters From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

(15) Income Taxes Uncertain Tax Positions The Company accounts for income taxes in accordance with ASC 740. The guidance requires the Company to recognize in its consolidated financial statements the impact of a tax position if that position is more likely than not to be sustained upon examination, based on the technical merits of the position. The Company has no current or deferred tax due to current and projected losses for the year. At July 31, 2025 the Company had no uncertain tax positions. The Company does not expect any material increases or decreases in its income tax expense or benefit in the next twelve months, related to examinations or uncertain tax positions. Net operating losses and credit carryforwards since inception remain open to examination by taxing authorities and will continue to remain open for a period of time after utilization. Tax Preservation Plan In June 2023, in order to protect the Company’s valuable tax assets related to its net operating losses from being limited or lost under Section 382 of the Internal Revenue Code, the Company adopted a Tax Benefits Preservation Plan (the “Plan”). Pursuant to the Plan, the Board declared a dividend of one preferred share purchase right (each, a “Right”) 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’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 4.99% or more of the outstanding common stock without approval by potentially subjecting any such person or group to significant dilution. The Plan was approved by shareholders by a non-binding advisory vote at the Company’s Annual Meeting held on February 28, 2024. The Company determined the grant date fair value of the Rights using an option-pricing model. The amount was immaterial to the consolidated financial statements and deemed to be de minimis, and accordingly was not recorded to the financial statements. Impact of the One Big Beautiful Act (“OBBBA”) On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law, introducing various changes to U.S. federal income tax provisions, including modifications to bonus depreciation, interest expense limitations, research and development expense treatment, and international tax rules. Under Accounting Standards Codification (ASC) 740, the effects of changes in tax law are required to be recognized in the period that includes the enactment date. The Company has evaluated the provisions of the OBBBA and determined that the enactment of the legislation did not have a material impact on its income tax provision, deferred tax assets or liabilities, or estimated annual effective tax rate for the quarter ended July 31, 2025. The Company will continue to monitor the potential future impacts of the OBBBA, including provisions that become effective in subsequent periods, and will reflect any material changes in its financial statements as appropriate.

(16) Operating Segments and Geographic Information The Company operates as one operating segment. The Company’s chief operating decision maker (the “CODM”) is its Chief Executive Officer, who reviews financial information on a consolidated basis and utilizes net loss for purposes of making operating decisions, assessing financial performance of the consolidated Company, and making resource allocation decisions. The CODM also reviews total assets. While assets may move throughout the world to support our revenue projects, for reporting purposes they are included in North America total assets. Revenue and expenses are generally attributed to the operating unit that bills the customers. The following table presents selected financial information with respect to the Company’s single operating segment and its significant segment expenses for the three months ended July 31, 2025 and 2024, respectively: Schedule of Operating Segment Expenses <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif;
