GEOS US Equity☆

Item 1A. Risk Factors

In evaluating the Company’s business, you should consider the following discussion of risk factors, in addition to other information contained in this report and in the Company’s other public filings with the U.S. Securities and Exchange Commission. Any such risks could materially and adversely affect our business, financial condition, results of operations, cash flow and prospects. However, the risks described below are not the only risks facing us. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition, results of operations, cash flow and prospects.

External Factors that Could Adversely Affect Us

Oil Commodity Price Levels Could Affect Demand for Our Oil and Gas Products, Which Could Materially and Adversely Affect Our Results of Operations and Liquidity.

Demand for many of our products and the profitability of our operations depend primarily on the level of worldwide oil and gas exploration activity. Prevailing oil and gas prices, with an emphasis on crude oil prices, and market expectations regarding potential changes in such prices significantly affect the level of worldwide oil and gas exploration activity. During periods of improved energy commodity prices, the capital spending budgets of oil and natural gas operators tend to expand, which results in increased demand for our customers' services leading to increased demand in our products. Conversely, in periods when these energy commodity prices deteriorate, capital spending budgets of oil and natural gas operators tend to contract causing demand for our products to weaken. Historically, the markets for oil and gas have been volatile and are subject to wide fluctuations in response to changes in the supply of and demand for oil and gas, market uncertainty and a variety of additional factors that are beyond our control. These factors include the level of consumer demand, regional and international economic conditions, weather conditions, domestic and foreign governmental regulations (including those related to climate change), price and availability of alternative fuels, political conditions, the war between Russia and Ukraine, instability and hostilities in the Middle East and other significant oil-producing regions, increases and decreases in the supply of oil and gas, the effect of worldwide energy conservation measures and the ability of the Organization of Petroleum Exporting Countries ("OPEC") to set and maintain production levels and prices of foreign imports.

Any material changes in oil and gas prices or other market trends, like slowing growth of the global economy, could adversely impact seismic exploration activity and would likely affect the demand for the Company's products and could materially and adversely affect its results of operations and liquidity. Generally, imbalances in the supply and demand for oil and gas will affect oil and gas prices and, in such circumstances, demand for our oil and gas products may be adversely affected when world supplies exceed demand.

The Ongoing Armed Conflict Between Russia and Ukraine Could Adversely Affect Our Business and Results of Operations.

In February 2022, the Russian Federation launched a full-scale military invasion of Ukraine, and Russia and Ukraine continue to engage in active and armed conflict as of November 2024. Although the length and impact of the ongoing military conflict is highly unpredictable, the conflict in Ukraine could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions. As a result of the invasion, the governments of several western nations, including the U.S., Canada, the United Kingdom and the European Union, implemented new and/or expanded economic sanctions and export restrictions against Russia, Russian-backed separatist regions in Ukraine, certain banks, companies, government officials, and other individuals in Russia and Belarus.

A portion of our oil and gas product manufacturing was conducted through our wholly-owned subsidiary Geospace Technologies Eurasia LLC ("GTE") in the Russian Federation. In August 2024, we sold these operations to a group of former employees of GTE. We have continued to purchase products from the new ownership and expect to continue to do so for the foreseeable future. However, the rapid changes in rules and implementation of new rules on imports and exports of goods involving Russia has also led to serious delays in getting goods to or from Russia as port authorities struggle to keep up with the changing environment. If imports of these products from the Russian Federation are restricted by government regulation, we may be forced to find other sources for the manufacturing of these products at potentially higher costs. The risk of doing business in the Russian Federation and other economically or politically volatile areas could adversely affect our operations and earnings.

We have no way to predict the duration, progress, or outcome of the military conflict in Ukraine. The extent and duration of the military action, sanctions, and resulting market disruptions could be significant and could potentially have substantial impact on the global economy and our business for an unknown period of time.

Our Foreign Subsidiaries and Foreign Marketing Efforts Are Subject to Additional Political, Economic, Legal and Other Uncertainties Not Generally Associated with Domestic Operations.

Based on customer billing data, revenue to customers outside the United States accounted for approximately 37% of our revenue during fiscal year 2025; however, we believe the percentage of revenue outside the United States is likely higher since many of our products are first delivered to a domestic location and ultimately shipped to a foreign location. We again expect revenue outside of the United States to represent a substantial portion of our revenue for fiscal year 2026 and subsequent years.

Foreign revenue is subject to special risks inherent in doing business outside of the United States including the risk of war, terrorist activities, civil disturbances, embargo and government activities, shifting foreign attitudes about conducting business activities with the United States, restrictions of the movement and exchange of funds, inhibitions of our ability to collect accounts receivable or repossess our rental equipment, international sanctions, expropriation and nationalization of our assets or those of our customers, currency fluctuations, devaluations and conversion restrictions, confiscatory taxation or other adverse tax policies and governmental actions that may result in the deprivation of our contractual rights, all of which may disrupt markets or our operations.

Foreign revenue is also generally subject to the risk of compliance with additional laws, including tariff regulations and import and export restrictions. International revenue transactions for our products containing hydrophones require prior U.S. government approval in the form of an export license, which may be withheld by the U.S. government based upon factors which we cannot predict.

10

Increases in Tariffs, Trade Restrictions or Taxes on our Products Could Have an Adverse Impact on our Operations.

Approximately 37% of our revenue for fiscal year 2025 was generated from customers outside of the U.S. We also purchase a portion of our raw materials from suppliers in China and other foreign countries. The commerce we conduct in the international marketplace makes us subject to tariffs, trade restrictions and other taxes when the raw materials we purchase, and the products we ship, cross international borders. Trade tensions between the United States and China, as well as those between the U.S. and Canada, Mexico, and other countries have been escalating in recent years. In addition, the current presidential administration is utilizing tariffs to fortify domestic tax revenue which could further impact our business and operations, due to potential trade wars as a result of the implementation of tariffs or otherwise. Historically, trade tensions have led to a series of tariffs imposed by the U.S. on imports from China, as well as retaliatory tariffs imposed by China on imports from the U.S. If the U.S. and China are able to negotiate the issues to restore a mutually advantageous and fair trading regime, the increased tariffs could be eliminated. Certain raw materials we purchase from China are subject to these tariffs which has increased our manufacturing costs. Products we sell into certain foreign markets could also become subject to similar retaliatory tariffs making the products we sell uncompetitive to similar products not subjected to such import tariffs. Further changes in U.S. trade policies, tariffs, taxes, export restrictions or other trade barriers, or restrictions on raw materials including rare earth minerals, may limit our ability to produce products, increase our manufacturing costs, decrease our profit margins, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase raw materials, which could have a material adverse effect on our business, results of operations or financial conditions. It remains unclear as to the tariff related impact of the future geopolitical climate will bring to our operations.

Climate Change and Legislation Designed to Reduce Climate Change

The physical and regulatory effects of climate change could have a negative impact on our operations, our customers’ operations and the overall demand for our customers’ products and, accordingly, our services. There is an increasing focus of local, state, regional, national and international regulatory bodies on Greenhouse Gas ("GHG") emissions and climate change issues. Legislation to regulate GHG emissions has periodically been introduced in the U.S. Congress, and there has been a wide-ranging policy debate, both in the United States and internationally, regarding the impact of these gases and possible means for their regulation. These efforts have included consideration of cap-and-trade programs, carbon taxes, and GHG reporting and tracking programs and regulations that directly limit GHG emissions from certain sources. Some of the proposals would require industries to meet stringent new standards that would require substantial reductions in carbon emissions. Those reductions could be costly and difficult to implement. In the absence of federal GHG-limiting legislation, the EPA has determined that GHG emissions present a danger to public health and the environment and has adopted regulations that, among other things, establish construction and operating permit reviews for GHG emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions from certain oil and natural gas system sources, implement Clean Air Act emission standards directing the reduction of methane emissions from certain new, modified, or reconstructed facilities in the oil and natural gas sector, and together with the DOT, implement GHG emissions limits on vehicles manufactured for operation in the United States.

In April 2016, the United States signed the Paris Agreement, which requires countries to review and “represent a progression” in their nationally determined contributions, which set emissions reduction goals, every five years. Under the Paris Agreement, the United States has committed to reducing its greenhouse gas emissions by 50-52% by 2030 from its 2005 levels. However, the United States is currently scheduled to end its participation in the Paris Agreement in January 2026. In November 2021, the Unites States and other countries entered the Glasgow Climate Pact, which includes a range of measures designed to address climate change, including but not limited to the phase-out of fossil fuel subsidies, reducing methane emissions 30% by 2030, and cooperating toward the advancement of the development of clean energy. Several states and geographic regions in the United States have also adopted legislation and regulations to reduce emissions of GHGs, including cap and trade regimes and commitments to contribute to meeting the goals of the Paris Agreement.

11

It is not possible at this time to predict the timing and effects of climate change or whether additional climate-related legislation, regulations or other measures will be adopted at the local, state, regional, national and international levels. However, continued efforts by governments and non-governmental organizations to reduce GHG emissions appear likely, and additional legislation, regulation or other measures that control or limit GHG emissions or otherwise seek to address climate change could adversely affect our customers and our business. Because our business depends on the level of oil exploration, existing or future laws or regulations related to GHGs and climate change, including incentives to conserve energy or use alternative energy sources, could negatively impacted our business if such laws or regulations reduce demand for our customers’ products and, accordingly, our services.

These risks may result in our customers restricting or cancelling exploration or production activities which also could reduce demand for our products and services. In addition to regulatory impacts, the occurrence of weather events caused or exacerbated by climate change could impact local, national or global commodity demand or availability in ways that could be material to our business and/or the businesses of our customers.

We Operate in Highly Competitive Markets, and Our Competitors May Be Able to Provide Newer or Better Products Than We Are Able to Provide.

The markets for most of our products are highly competitive. Many of our existing and potential competitors have substantially greater marketing, financial and technical resources than we do. Some competitors currently offer a broader range of instruments and equipment for sale than we do and may offer financing arrangements to customers on terms that we may not be able to match. In addition, new competitors may enter the market and competition could intensify.

Revenue from our products may not continue at current volumes or prices if current competitors or new market entrants introduce new products with better features, performance, price or other characteristics than our products. Competitive pressures or other factors may also result in significant price competition that could have a material adverse effect on our results of operations.

A General Downturn in the Economy in Future Periods May Adversely Affect Our Business.

Economic slowdowns, currently or in the future, in the United States, China or India, could adversely affect our business in ways that we cannot predict. During times of economic slowdown, our customers may reduce their capital expenditures and defer or cancel pending projects and product orders. Such developments occur even among customers that are not experiencing financial difficulties. During times of economic slowdowns, some of our customers have (and other customers may have) undergone restructuring or bankruptcy that has or could adversely impact our revenues and profitability. Any economic downturn may adversely affect the demand for oil and gas generally or cause volatility in oil and gas commodity prices and, therefore, adversely affect the demand for delivery of our oil and gas products. It could also adversely affect the demand for consumer and industrial products, which could in turn adversely affect our Adjacent Markets business segment. To the extent these factors adversely affect other companies in the industries we serve, there could be an oversupply of products and services and downward pressure on pricing for our products and services, which could adversely affect us. Additionally, bankruptcies or financial difficulties among our oil and gas customers could reduce our cash flow and adversely impact our liquidity and profitability. For a discussion of the customers of our oil and gas products, see “The Limited Market for Our Oil and Gas Products Can Affect Our Revenue,” below.

Risks Associated with Our Business Strategy and Operations

Our New Products Require a Substantial Investment by Us in Research and Development Expense and May Not Achieve Market Acceptance.

Our outlook and assumptions are based on various macro-economic factors and internal assessments, and actual market conditions could vary materially from those assumed. In recent years, we have incurred significant expenditures to fund our research and development efforts, and we intend to continue those expenditures in the future. However, research and development is by its nature speculative, and we cannot assure you that these expenditures will result in the development of new products or services or that any new products and services we have developed recently or may develop in the future will be commercially marketable or profitable to us. In particular, we have incurred substantial expenditures to develop our ocean bottom nodal seismic data acquisition systems, as well as other products for PRM applications. In addition, we try to use some of our capabilities to supply products to smart water and intelligent industrial products. We cannot assure you that we will realize our expectations regarding acceptance of and revenue generated by our new products and services in existing or new markets.

12

The Short-Term Nature of Our Order Backlog for Sales of Our Oil and Gas Products and Delayed or Canceled Customer Orders May Cause Us to Experience Fluctuations in Quarterly Results of Operations.

Historically, the rate of new orders for the sale of our oil and gas products has varied substantially from quarter to quarter. Moreover, we typically operate, and expect to continue operating, on the basis of orders in-hand for our products before we commence substantial manufacturing “runs.” The short-term nature of our order backlog for most of our oil and gas products generally does not allow us to predict with any accuracy demand for our products more than approximately three months in advance. Thus, our ability to replenish orders and the completion of orders, particularly large orders for deep water PRM projects, can significantly impact our operating results and cash flow for any quarter, and results of operations for any one quarter may not be indicative of results of operations for future quarters.

Additionally, customers can delay or even cancel orders and rental contracts before product delivery occurs. For larger orders which generally require us to make a substantial capital investment in our inventories or rental fleet, we attempt to negotiate for a non-refundable deposit or cancellation penalties depending on our relationship with the customer. However, such deposits or penalties, even when obtained, may not fully compensate us for our inventory investment and forgone profits if the order is ultimately cancelled.

These periodic fluctuations in our operating results and the impact of any order delays/cancellations could adversely affect our stock price.

Our Credit Risk Could Increase and We May Incur Credit Loss Write-Offs If Our Customers Continue to Face Difficult Economic Circumstances.

While we believe that our allowance for credit losses is adequate in light of known circumstances, additional amounts attributable to uncollectible accounts and notes receivable and credit loss write-offs may have a material adverse effect on our future results of operations. Many of our oil and gas customers are not well capitalized and as a result cannot always pay our invoices when due. We have in the past incurred write-offs in our accounts and notes receivable due to customer credit problems. We have found it necessary from time to time to extend trade credit, including promissory notes, to long-term customers and others where some risks of non-payment exist. Many of our oil and gas customers continue to experience significant liquidity difficulties, which increase those credit risks, due to prolonged periods of low crude oil prices. An increase in the level of credit losses and any deterioration in our credit risk could adversely affect the price of our stock. In addition, we rent equipment to our oil and gas customers who utilize such equipment in various countries around the world. If these customers experience financial difficulties, it could be difficult or impossible to retrieve our rental equipment from foreign countries.

The Industries in Which We Operate are Characterized by Rapid Technological Development and Product Obsolescence, Which May Affect Our Ability to Provide Product Enhancements or New Products on a Timely and Cost-Effective Basis.

Our instruments and equipment are constantly undergoing rapid technological improvement. Our future success depends on our ability to continue to

● improve our existing product lines,

● address the increasingly sophisticated needs of our customers,

● maintain a reputation for technological leadership,

● maintain market acceptance of our products,

● anticipate changes in technology and industry standards,

● respond to technological developments on a timely basis and

● develop new markets for our products and capabilities.

Current competitors or new market entrants may develop new technologies, products or standards that could render our products obsolete. We cannot assure you that we will be successful in developing and marketing, on a timely and cost-effective basis, product enhancements or new products that respond to technological developments, that are accepted in the marketplace or that comply with new industry standards. Additionally, in anticipation of customer product orders, from time to time we acquire substantial quantities of inventories, which if not sold or integrated into products within a reasonable period of time could become obsolete. In such case, we would be required to impair the value of such inventories on our balance sheet.

13

The Limited Market for Oil and Gas Products and Border and Perimeter Security Products Can Affect Our Revenue.

We generally market many of our oil and gas products to seismic service contractors. We estimate that fewer than 30 oil and gas seismic contracting companies are currently operating in countries other than those operating in the Russian Federation and the former Soviet Union, India, the People’s Republic of China and certain Eastern European countries, where such information is difficult to verify. We estimate that fewer than 15 seismic contractors are engaged in marine seismic exploration activities. Due to these market factors, a relatively small number of customers, some of whom are experiencing financial difficulties, account for most of our oil and gas product revenue. From time to time, these contractors have sought to vertically integrate and acquire our competitors, which has influenced their supplier decisions before and after such transactions. In addition, consolidation among our customers may further concentrate our business to a limited number of customers and expose us to increased risks related to dependence on a small number of customers. We market our seabed PRM systems' products to large oil and gas companies. During the third quarter of fiscal year 2025, we entered into large-scale seabed PRM system contract, our first since 2014. Our border and perimeter products are sold to a small number of agencies within the U.S. government. The loss of a small number of these customers, and particularly our oil and gas customers, could materially and adversely impact our future revenues.

We Cannot Be Certain of the Effectiveness of Patent Protection on Our Products.

We hold and from time to time apply for certain patents relating to some of our products. We cannot assure you that our patents will prove enforceable or free of challenge, that any patents will be issued for which we have applied or that competitors will not develop functionally similar technology outside the protection of any patents we have or may obtain.

Our Strategy of Renting Our Oil and Gas Seismic Products Exposes Us to Additional Risks Relating to Equipment Recovery, Rental Renewals, Technological Obsolescence and Impairment of Assets.

Our rental fleet of oil and gas seismic equipment represents a significant portion of our assets and accounts for a significant portion of our revenue. Equipment we rent to our customers is frequently located in foreign countries where retrieval of the equipment after the termination of the rental agreement is difficult or impossible if the customer does not return the equipment. The costs associated with retrieving this equipment or the loss of equipment that is not retrieved could be significant and could adversely affect our operations and earnings.

The advancement of seismic technology having a significant competitive advantage over the equipment in our rental fleet could have an adverse effect on our ability to profitably rent and/or sell this equipment. Significant improvements in technology may also require us to record asset impairment charges to write down the value of our rental fleet investment and to invest significant sums to upgrade or replace our rental fleet with newer equipment demanded by our customers. In addition, rental contracts may not be renewed for equipment in our rental fleet. Significant technological improvements by our competitors could have an adverse effect on our results of operations and earnings.

Our equipment rental business has high fixed costs, which primarily consist of depreciation expenses. In periods of declining rental revenue, these fixed costs generally do not decline. As a result, any significant decline in rental revenue caused by reduced demand could adversely affect our results of operations.

Our Diversification Strategy Using both Organic Expansion and Acquisitions May Not Be Successful.

We seek to grow our business through a combination of organic initiatives and strategic acquisitions. Our ability to achieve organic growth depends on factors such as customer retention, market demand, product innovation, and our ability to attract and retain key personnel. There can be no assurance that our efforts will result in increased revenues or profitability.

In addition, we may pursue acquisitions to expand our market presence, product offerings, or geographic reach. Acquisitions involve numerous risks, including difficulties in identifying suitable targets, integrating operations, realizing anticipated synergies, retaining key employees, and managing increased operational complexity. We may also face unforeseen liabilities or costs associated with acquired businesses.

If we are unable to successfully execute our organic growth initiatives or effectively integrate and manage acquired businesses, our business, financial condition, and results of operations could be adversely affected.

We Rely on Key Suppliers for Certain Components Used in Our Products.

Certain electronic components used in our land and marine wireless products are purchased from two single source suppliers. In the event a change in one or both suppliers is necessary, significant engineering efforts would be required by us, which could adversely affect our financial performance.

For our imaging products, we purchase all of our thermal film from one manufacturer. Except for the film sold to us by this manufacturer, we know of no other source for thermal film that performs as well in our imaging equipment. If the manufacturer were to discontinue producing thermal film, were to become unwilling to contract with us on competitive terms, or were unable to supply thermal film in sufficient quantities to meet our requirements, our ability to compete in the direct thermal imaging marketplace could be impaired, which could adversely affect our financial performance.

Our Success Depends Upon a Limited Number of Key Personnel.

Our success depends on attracting and retaining highly skilled professionals. A number of our employees are highly-skilled engineers and other professionals. In addition, our success depends to a significant extent upon the abilities and efforts of the members of our senior management team. If we fail to continue to attract and retain such professionals, our ability to compete in the industry could be adversely affected.

We Have a Minimal Disaster Recovery Program at Our Houston Facilities.

Due to its proximity to the Texas Gulf Coast, our facilities in Houston, Texas are annually subject to the threat of hurricanes and the aftermath that follows. Hurricanes may cause, among other types of damage, the loss of electrical power for extended periods of time. If we lost electrical power at our Pinemont facility, or if a fire or other natural disaster occurred, we would be unable to continue our manufacturing operations during the power outage because we do not own a generator or any other back-up power source large enough to provide for our manufacturing power consumption needs. Additionally, we do not have an alternative manufacturing or operating location in the United States. Therefore, a significant disruption in our manufacturing operations could materially and adversely affect our business operations during an extended period of a power outage, fire or other natural disaster. We have a back-up generator to provide power for our information technology operations. We store our back-up data offsite and we replicate our mission critical data to an alternative cloud-based data center on a real-time basis. In the event of a major service interruption in our data center, we believe we would be able to activate our mission critical applications within less than 24 hours.

Our Storage of Lithium Batteries is a Fire Hazard.

We use lithium batteries in several of our products which are stored at our Pinemont facility. These batteries are known to pose significant fire hazards. Should a fire occur, it could result in personal injuries, damage to our facility and likely interruptions to our manufacturing operations. Such an event could materially and adversely affect our business operations. We currently are evaluating our fire suppression system in an effort further to mitigate this risk.

15

Our Credit Agreement Imposes Restrictions on Our Business.

We and several of our subsidiaries domiciled in the United States are parties to a credit agreement. Borrowings under the credit agreement will be secured by substantially all of our domestic assets, except for certain excluded property. The credit agreement limits the incurrence of additional indebtedness, contains covenants that require us to maintain (i) a certain amount of consolidated tangible net worth and liquidity and (ii) minimum asset and interest coverage ratios. The credit agreement also contains other covenants customary in agreements of this type. Our ability to comply with these restrictions may be affected by events beyond our control, including, but not limited to, prevailing economic, financial and industry conditions and continuing declines in our product revenue. The breach of any of these covenants or restrictions, as well as any failure to make a payment of interest or principal when due, could result in a default under the credit agreement. Such a default would permit our lender to declare any amount borrowed from it to be due and payable, together with accrued and unpaid interest, and our ability to borrow under the credit agreement could be terminated. If we are unable to repay any debts owed to our lender, the lender could proceed against the collateral securing such debt. While we intend to seek alternative sources of cash in such a situation, there is no guarantee that any alternative cash source would be available or would be available on terms favorable to us.

Reliance on Third Party Subcontractors Could Adversely Affect Our Results of Operations and Reputation.

We may rely on subcontractors to complete certain projects. The quality and timing of production and services by our subcontractors is not totally under our control. Reliance on subcontractors gives us less control over a project and exposes us to significant risks, including late delivery, substandard quality and high costs. The failure of our subcontractors to deliver quality products or services in a timely manner could adversely affect our profitability and reputation.

The High Fixed Costs of Our Operations Could Adversely Affect Our Results of Operations.

We have a high fixed cost structure primarily consisting of (i) depreciation expenses associated with our rental equipment and (ii) fixed manufacturing costs including salaries and benefits, taxes, insurance, maintenance, depreciation and other fixed manufacturing costs. In regards to our rental equipment, large declines in the demand for rental equipment could result in substantial operating losses due to the on-going fixed nature of rental equipment depreciation expense. Concerning our product manufacturing costs, in periods of low product demand our fixed costs generally do not decline or may decline only in modest increments. Therefore, lower demand for our rental equipment and manufactured products could adversely affect our results of operations.

Legal and Compliance Risks

Our Global Operations Expose Us to Risks Associated with Conducting Business Internationally, Including Failure to Comply with U.S. Laws Which Apply to International Operations, Such as the Foreign Corrupt Practices Act and U.S. Export Control Laws, as Well as the Laws of Other Countries.

We have offices in Brazil, Colombia, Canada and the United Kingdom, in addition to our offices in the United States. In addition to the risks that are inherent in conducting business internationally, we are also liable for compliance with international and U.S. laws and regulations that apply to our international operations. These laws and regulations include data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export control laws, U.S. laws such as the Foreign Corrupt Practices Act and similar laws in other countries which also prohibit certain payments to governmental officials or certain payments or remunerations to customers. Many of our products are subject to U.S. export law restrictions that limit the destinations and types of customers to which our products may be sold, or require an export license in connection with revenue transactions outside the United States. Given the high level of complexity of these laws, there is a risk that some provisions may be inadvertently breached, for examples through the negligent or the unauthorized intentional behavior of individual employees, or our failure to comply with certain formal documentation requirements or otherwise. Additionally, we may be held liable for actions taken by our local dealers and partners. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products in one or more countries and could materially damage our reputation, our brands, our international expansion efforts, our ability to attract and retain employees, and our business and operating results.

16

Because We Have No Plans to Pay Any Dividends for the Foreseeable Future, Investors Must Look Solely to Stock Appreciation for a Return on Their Investment in Us.

We have not paid cash dividends on our common stock since our incorporation and do not anticipate paying any cash dividends in the foreseeable future. Any payment of cash dividends in the future will be dependent on the amount of funds legally available, our financial condition, capital requirements, loan covenants and other factors that our Board of Directors may deem relevant. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

We Have a Relatively Small Public Float, and Our Stock Price May be Volatile.

At September 30, 2025, we have approximately 12.6 million shares outstanding held by non-affiliates. This limited number of shares outstanding results in a relatively limited market for our common stock. Our daily trading volume for the year ended September 30, 2025 averaged approximately 122,000 shares. Our small float and daily trading volumes have in the past caused, and may in the future result in, significant volatility in our stock price.

Financial and Accounting Risks

Unfavorable Currency Exchange Rate Fluctuations Could Adversely Affect Our Results of Operations.

Substantially all of our third-party revenue from the United States is invoiced in U.S. dollars, though from time to time we may invoice revenue transactions in foreign currencies including intercompany sales. As a result, we may be subject to foreign currency fluctuations on our revenue. The reporting currency for our financial statements is the U.S. dollar. However, the assets, liabilities, revenue and costs of our Canadian and United Kingdom subsidiaries and our Brazilian and Colombian branch offices are denominated in currencies other than U.S. dollars. To prepare our consolidated financial statements, we must translate those assets, liabilities, revenue and expenses into U.S. dollars at then-applicable exchange rates. Consequently, increases and decreases in the value of the U.S. dollar versus these other currencies will affect the amount of these items in our consolidated financial statements, even if their value has not changed in their original currency. These translations could result in significant changes to our results of operations from period to period. For the fiscal year ended September 30, 2025, approximately 4% of our consolidated revenue was related to the operations of our foreign subsidiaries and branches.

Our Long-Lived Assets May be Subject to Impairment.

We periodically assess our long-lived assets for impairment. Significant sustained future decreases in crude oil and natural gas prices may require us to write down the value of our long-lived assets in our Energy Solutions business segment, including our manufacturing facilities, manufacturing equipment and rental equipment if future cash flows anticipated to be generated from these assets fall below the asset’s net book value. Furthermore, we may be required to write down the value of other intangible assets related to our acquisition of the OptoSeis® fiber optic sensing technology or the goodwill and other intangible assets related to our Aquana or Geovox acquisitions if sufficient cash flows are not generated to recover the carrying value of such assets. If we are forced to write down the value of our long-lived assets, these non-cash asset impairments could adversely affect our results of operations.

Should We Fail to Maintain an Effective System of Internal Control Over Financial Reporting, We May Not Be Able to Accurately Report Our Financial Results and Prevent Material Fraud, Which Could Adversely Affect the Value of Our Common Stock.

Effective internal control over financial reporting is necessary for us to provide reliable financial reports and effectively prevent and detect material fraud. If we cannot provide reliable financial reports or prevent or detect material fraud, our operating results could be misstated. There can be no assurances that we will be able to prevent control deficiencies from occurring, which could cause us to incur unforeseen costs, negatively impact our results of operations, cause the market price of our common stock to decline, or have other potential adverse consequences.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Cybersecurity Breaches and Other Disruptions of Our Information Technology Network and Systems Could Adversely Affect Our Business.

Our Senior Vice President of Information Technology manages our security program. Oversight of the program occurs via IT metrics-based updates provided to an Information Technology Steering team (consisting of the executive officers and other key employees of the Company) on a quarterly basis. Additionally, multiple elements of our cybersecurity security program are tested internally and externally on a bi-yearly basis in alignment with our Sarbanes-Oxley information security controls, and we engage independent third parties annually to assess the risks associated with our information technology assets. Our cybersecurity program is part of our enterprise risk management strategy and includes policies and procedures designed to safeguard the confidentiality, integrity, and availability of our information assets. Lastly, a cybersecurity risk assessment is provided to our Board of Directors on an annual basis which includes metrics, security incidents, key risk indicators, and risk mitigation plans as well as on the status of material risks, mitigation measures, and incidents related to such risks. Our Board of Directors has overall responsibility for risk oversight, with the Information Technology Steering team assisting the Board in performing this function based on its respective areas of expertise. As such, the Information Technology Steering team performs materiality determinations of cyber incidents and advises the Board of Directors accordingly.

We maintain a comprehensive cybersecurity risk management program that aligns to the National Institute of Standards and Technology (NIST) Cyber Security Framework and adopts a variety of cybersecurity best practices across the enterprise. We leverage industry-leading cybersecurity vendors that provide the following capabilities: Managed Detection and Response (MDR); a Security Operations Center (SOC) that monitors the Company’s IT assets on a 24x7x365 basis; tools to interdict emails with phishing links and malware payloads; data leak protection tools that provide real-time interdiction of data transfers outside of normal business usage; vulnerability detection and automated patching tools; firewalls and instruction detection systems; multi-factor authentication mechanisms; mobile device management systems; penetration testing; and various third-party assessments. Our critical IP data is maintained on segmented, access-controlled data stores. We utilize a variety of backup mechanisms for its data including both warm and cold storage solutions. Lastly, we utilize token-based technologies to support Payment Card Industry Data Security Standard (PCI DSS) compliance safe handling and protection of credit card data.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis of the major elements of our consolidated financial statements. You should read this discussion and analysis together with our consolidated financial statements, including the accompanying notes, and other detailed information appearing elsewhere in this Annual Report on Form 10-K, including under the heading “Risk Factors.” The discussion of our financial condition and results of operations includes various forward-looking statements about our markets, the demand for our products and services and our future plans and results. These statements are based on assumptions that we consider to be reasonable but that could prove to be incorrect. For more information regarding our assumptions, you should refer to the section entitled “Cautionary Note Regarding Forward-Looking Statements and Assumptions” below.

Cautionary Note Regarding Forward-Looking Statements and Assumptions

This Annual Report on Form 10-K and the documents incorporated by reference herein, if any, contain “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements can be identified by terminology such as “may”, “will”, “should”, “intend”, “expect”, “plan”, “budget”, “forecast”, “anticipate”, “believe”, “estimate”, “predict”, “potential”, “continue”, “evaluating” or similar words. Statements that contain these words should be read carefully because they discuss our future expectations, contain projections of our future results of operations or of our financial position or state other forward-looking information. Examples of forward-looking statements include, among others, statements that we make regarding our expected operating results, the adoption, results and success of our rollout of our Aquana smart water valves and cloud-based control platform, future demand for our Quantum security solutions, the adoption and sale of our products in various geographic regions, potential tenders for PRM systems, sales or rentals for ocean bottom nodes, the adoption of Quantum's SADAR®product monitoring of subsurface reservoirs, the completion of new orders for channels of our PioneerTM system, the fulfillment of customer payment obligations, the impact of the current armed conflict between Russia and Ukraine, our ability to manage changes and the continued health or availability of management personnel, volatility and direction of oil prices, anticipated levels of capital expenditures and the sources of funding therefor, and our strategy for growth, product development, market position, financial results and the provision of accounting reserves. These forward-looking statements reflect our current judgment about future events and trends based on the information currently available to us. However, there will likely be events in the future that we are not able to predict or control. The factors listed under the caption “Risk Factors”, as well as cautionary language in this Annual Report on Form 10-K, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. Such examples include, but are not limited to, the failure of our acquisitions to yield positive operating results and decreases in commodity price levels which could reduce demand for our products, the failure of our products to achieve market acceptance (despite substantial investment by us), our sensitivity to short term backlog, delayed or cancelled customer orders, product obsolescence resulting from poor industry conditions or new technologies, bad debt write-offs associated with customer accounts, inability to collect on promissory notes, lack of further orders for our ocean bottom rental equipment, failure of our Quantum products to be adopted by the border and perimeter security market, or a decrease in such market due to governmental changes, and infringement or failure to protect intellectual property. The occurrence of the events described in these risk factors and elsewhere in this Annual Report on Form 10-K could have a material adverse effect on our business, results of operations and financial position, and actual events and results of operations may vary materially from our current expectations. We assume no obligation to revise or update any forward-looking statement, whether written or oral, that we may make from time to time, whether as a result of new information, future developments or otherwise.

Background

We design and manufacture seismic instruments and equipment and primarily market these products to the oil and gas industry to locate, characterize and monitor hydrocarbon producing reservoirs. We also market our seismic products to other industries for vibration monitoring, border and perimeter security and various geotechnical applications. We design and manufacture Hydroconn® water meter connector products, IoT water values, imaging equipment and provide contract manufacturing services. For further information on the nature of our operations, see the information under the heading “Business” in this Annual Report on Form 10-K.

Consolidated Results of Operations

As we have reported in the past, our revenue and operating profits have varied significantly from quarter-to-quarter, and even year-to-year, and are expected to continue that trend in the future, especially when our quarterly or annual financial results are impacted by the presence or absence of relatively large, but somewhat unpredictable, sales of our oil and gas PRM systems and/or wireless seismic data acquisition systems for land and marine applications.

21

We report and evaluate financial information for three segments: Smart Water, Energy Solutions and Intelligent Industrial. Summary financial data by business segment follows (in thousands):

YEAR ENDED SEPTEMBER 30,

Smart Water

Energy Solutions

Intelligent Industrial

Corporate

Consolidated Totals

Overview

Growing industry acceptance of our water meter cables and connectors provides a strong enabler for additional revenue from our Smart Water segment. Automatic meter reading efficiencies in operations and improved customer service has begun to be understood by the municipalities of the United States. We expect this portion of our business to continue to grow for the foreseeable future. Additionally, we anticipate this segment to see revenue contributions from our Aquana smart water valve and IoT technology products as market traction and increased sales backlog continues to gather. Given the well-known and often extreme volatility experienced in our Energy Solutions segment, careful expansion of products and market diversity in our Smart Water and Intelligent Industrial segments has been a longstanding part of our strategic vision and reflects our on-going diversification efforts.

Our Energy Solution segment saw a shift from rentals of our ocean bottom nodes to purchases of the equipment in fiscal years 2024 and 2025. This shift signifies our customer’s recognition of future backlog to justify ownership versus renting the nodes. We do not expect significant expansion of the ocean bottom nodal market, because we expect the market is saturable and future rental fleet use will come from our customers' need to temporarily expand their nodal fleet. We expect our Energy Solutions segment to provide a significant portion of our revenue for years to come, but in diminishing portion to our other segments. During the third quarter of fiscal year 2025, we entered into a PRM contract. The duration of the contract is expected to be approximately 18 months. Revenue will be recognized in our Energy Solutions segment over the duration of the contract.

We continue to maintain a strong balance sheet with no debt. Our current liquidity enables our ability to seek out business acquisitions and allows us to continue investments in capital assets and product research and development, which have historically driven revenue growth.

22

Fiscal Year 2025 Compared to Fiscal Year 2024

Consolidated revenue for fiscal year 2025 was $110.8 million, a decrease of $24.8 million, or 18.3%, from fiscal year 2024. The decrease in revenue was primarily due to lower product revenue from our Energy Solutions segment. Revenue for fiscal year 2025 included a $17 million sale of ocean bottom nodes structured as a sales-type lease. However, in comparison, revenue for fiscal year 2024 included a $30 million sale of our Mariner® shallow water ocean bottom nodes. The decrease was also attributable to a decrease in our wireless marine rental revenue. The decrease in consolidated revenue for fiscal year 2025 was partially offset by an increase in demand for our Hydroconn® cable and connector products from our Smart Water segment.

Consolidated gross profit for fiscal year 2025 was $32.9 million, a decrease of $19.7 million, or 37.4%, from fiscal year 2024. The decrease in gross profit was primarily due to a decrease in ocean bottom nodes product revenue and a lower utilization of our rental fleet, and the operating costs of our rental fleet are primarily depreciation expense, which is not variable with revenue. The decrease in gross profit was also attributable to low gross margins on sales of our land-based wireless products due to very strong price competition on these products and due to an increase in tariffs on the raw materials we purchase.

Consolidated operating expenses for fiscal year 2025 were $48.8 million, an increase of $3.3 million, or 7.3%, from fiscal year 2024. The increase was primarily due to (i) higher personnel costs, including severance costs and acceleration of stock-based compensation expense and (ii) an increase in sales and marketing costs. The increase was partially offset by a $2.8 million impairment charge on intangible assets in the prior year.

In June 2025, we sold our real property located at 4318 Northfield Lane Houston, Texas. The 17.3-acre property served as additional property for our main campus and contained legacy structures used to support our manufacturing and warehousing operations We recognized a gain on disposal of property of $4.6 million during the third quarter of fiscal year 2025. The gain is included as a component of income (loss) from operations in the accompanying statements of operations.

Segment Results of Operations

Fiscal Year 2025 Compared to Fiscal Year 2024

Smart Water

Revenue

Revenue from our Smart Water products for fiscal year 2025 increased $3.4 million, or 10.4%, from the prior fiscal year. The increase was primarily due to an increase in demand for our Hydroconn® cable and connector products.

Operating Income

Operating income from our Smart Water products for fiscal year 2025 decreased $3.6 million, or 38.5%, from the prior fiscal year. The decrease was primarily due to an increase in sales and marketing and research and development costs associated with our increase in revenue. The decrease was also attributable to lower gross margins due to changes in the mix of products sold proportionally affecting the allocation of manufacturing overhead and other costs of revenue to our business segments.

Energy Solutions

Revenue

Revenue from our Energy Solutions products for fiscal year 2025 decreased $27.3 million, or 35.0%, from fiscal year 2024. The components of this decrease were as follows:

23

Operating Income

Operating income associated with our Energy Solutions products for fiscal year 2025 decreased $18.2 million, or 97.9%, from the prior fiscal year. The decrease was primarily due to (i) the decrease in revenues and related gross profits and (ii) higher research and development expenses, primarily personnel costs.

Intelligent Industrial

Revenue

Revenue from our Intelligent Industrial products for fiscal year 2025 decreased $0.9 million, or 3.7%, from the prior fiscal year. The decrease was primarily due to (i) revenue recognized for fiscal year 2024 on a government contract completed in the fourth quarter of fiscal year 2024 and (ii) lower demand for our imaging products. The decrease was partially offset by an increase in demand for our sensor products and contract manufacturing services.

Operating Loss

Operating loss from our Intelligent Industrial products for fiscal year 2025 decreased $2.4 million, or 35.3%, from the prior fiscal year. The decrease in operating loss was primarily due to a $2.8 million non-cash impairment of intangible assets recorded in the prior fiscal year. The decrease in operating loss for fiscal year 2025 was partially offset by (i) the decrease in revenue and (ii) lower gross margins due to changes in the mix of products sold proportionally affecting the allocation of manufacturing overhead and other costs of revenue to our business segments.

24

Liquidity and Capital Resources

At September 30, 2025, we had $26.3 in cash and cash equivalents. For fiscal year 2025, we used $22.2 million of cash from operating activities. Uses of cash included (i) our net loss of $9.7 million, offset by non-cash charges of $14.6 million resulting from deferred income taxes, depreciation, amortization, accretion, inventory obsolescence, stock-based compensation and provision for credit losses, (ii) a $7.6 million increase in inventories for the strategic purchase of long lead-time components needed for use in wireless products, valves and contract manufacturing, (iii) $4.2 million increase in trade accounts and notes receivable due to timing of collections from customers and (iv) $1.3 million increase in other assets, primarily due to prepaid product purchases. These uses of cash were partially offset by a i) $4.8 increase in other liabilities primarily related to customer deposits and (ii) $2.4 million increase in trade accounts payable due to timing of payments to our suppliers.

For fiscal year 2025, we generated cash of $42.7 million in investing activities. Sources of cash consisted of (i) $30.4 million from the sale of short-term investments, (ii) $8.7 million of proceeds from the sale of property, plant and equipment and (iii) $14.2 million in proceeds from the sale of rental equipment. These sources of cash were partially offset by (i) $8.0 million for additions to our property, plant and equipment, (ii) $1.1 million for additions to our equipment rental fleet and (iii) $1.8 million paid for our Geovox acquisition. We expect fiscal year 2026 cash investments in property, plant and equipment will be approximately $7 million. Our capital expenditures are expected to be funded from our cash on hand and internal cash flows or, if necessary, borrowings under our new credit agreement.

For fiscal year 2025, we used $1.0 million from financing activities which consisted of (i) $0.4 million in debt issuance costs related the renewal of our credit agreement and (ii) $0.6 million for the purchase of treasury stock pursuant to a stock buy-back program authorized by our board of directors. The program authorized us to repurchase up to $7 million of our common stock in open market transactions. The program was completed in the second quarter of fiscal year 2025.

On August 29, 2025, we amended our credit agreement (“the Agreement”) with Woodforest National Bank. The Agreement extended our revolving loan agreement, dated as of July 26, 2023, with Woodforest. The Agreement is for a three-year term and provides a revolving credit facility with a maximum availability of $25 million. Interest shall accrue on outstanding borrowings at 30 Day Term SOFR plus a margin equal to 2.75% per annum. We are required to make monthly interest payments on borrowed funds. The Agreement is secured by substantially all of our assets, except for certain excluded property. The Agreement requires us to maintain (i) a minimum consolidated tangible net worth of $85 million, (ii) minimum liquidity of $10 million, and (iii) a minimum asset coverage ratio of 2.00 to 1.00. The Agreement also requires us to maintain a springing minimum interest coverage ratio of at least 1.50 to 1.00, tested quarterly whenever (a) there is an outstanding balance on the revolving credit facility or (b) have letter of credit exposure greater than $1 million.

At September 30, 2025, we were in compliance with all covenants under the Agreement. At September 30, 2025, we could borrow approximately $8 million without violating any debt covenants. At September 30, 2025, we had no outstanding borrowings under the Agreement. We do not currently anticipate the need to borrow under the Agreement; however, we may decide to do so in the future, if needed.

Our available cash and cash equivalents was $26.3 million at September 30, 2025, which included $0.8 million of cash and cash equivalents held by our foreign subsidiaries and branch offices. In the absence of future profitable results of operations, we may need to rely on other sources of liquidity to fund our future operations, including executed rental contracts, available borrowings under the Agreement through its expiration in July 2028, sales or leveraging real estate assets, sales of rental assets and other liquidity sources which may be available to us. We currently believe that our cash will be sufficient to finance any future operating losses and planned capital expenditures through the next twelve months.

We do not have any obligations which meet the definition of an off-balance sheet arrangement, and which have or are reasonably likely to have a current or future effect on our financial statements or the items contained therein that are material to investors.

26

Contractual Obligations

Contingent Consideration

In August 2025, we acquired Geovox. In connection with the acquisition, we recorded an initial contingent earn-out liability of $2.5 million. Contingent payments, if any, will be based on eligible revenue generated during a four-year earn-out period. The maximum amount of contingent payments is $3.3 million.

In July 2021, we acquired Aquana. Pursuant to the merger agreement with Aquana, as amended ("the Merger Agreement"), the Company is subject to additional contingent cash payments to the former members of Aquana over a seven-year earn-out period. The contingent payments, if any, will be derived from certain eligible revenue generated during the earn-out period from products and services sold by Aquana. There is no maximum limit to the contingent cash payments that could be made. The Merger Agreement requires the continued employment of a certain key employee and former member of Aquana for the first five years of the seven-year earn-out period in order for any of Aquana’s former members to be eligible for any earn-out payments. Due to the continued employment requirement, no liability has been recorded for the estimated fair value of earn-out payments for this transaction. Earn-outs achieved are recorded as compensation expense when incurred.

See Note 19 to our consolidated financial statements in this Annual Report on Form 10-K for more information on our contractual contingencies.

Critical Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the use of estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We consider many factors in selecting appropriate operational and financial accounting policies and controls and in developing the estimates and assumptions that are used in the preparation of these financial statements. We continually evaluate our estimates, including those related to rental revenue recognition, bad debt reserves, inventory obsolescence reserves, business acquisitions and contingent earn-out liabilities. We base our estimates on historical experience and various other factors, including the impact from the current economic conditions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.

Our normal credit terms for trade receivables are 30 days. In certain situations, credit terms for trade receivables may be extended to 60 days or longer and such receivables generally do not require collateral. Additionally, we provide long-term financing in the form of promissory notes and sales-type leases when competitive conditions require such financing and, in such cases, we may require collateral. We perform ongoing credit evaluations of our accounts and financing receivables, and allowances are recognized for potential credit losses.

27

We record a write-down of our inventories when the cost basis of any manufactured product, including any estimated future costs to complete the manufacturing process, exceeds its net realizable value. Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out method, except that our subsidiary in the United Kingdom uses an average cost method to value its inventories.

We periodically review the composition of our inventories to determine if market demand, product modifications, technology changes, excessive quantities on-hand and other factors hinder our ability to recover our investment in such inventories. Management’s assessment is based upon historical product demand, estimated future product demand and various other judgments and estimates. Inventory obsolescence reserves are recorded when such assessments reveal that portions or components of our inventory investment will not be realized in our operating activities.

The value of our inventories not expected to be realized in cash, sold or consumed during our next operating cycle are classified as non-current assets in our consolidated balance sheets.

We accounted for our Geovox acquisition under the acquisition method of accounting. The total value of the consideration paid was allocated to the underlying net assets acquired, based on their respective estimated fair values. We utilized the excess earnings method to determine the fair value of assets and liabilities acquired, including discounted cash flows, external market values, valuations on recent transactions or a combination thereof, and believe that we used the most appropriate measure to value each asset or liability. The Company recognizes measurement-period adjustments in the reporting period in which the adjustment amounts, if any, are determined.

We established an earn-out liability in connection with our acquisition of Geovox in the fourth quarter of fiscal year 2025. We engaged the services of a valuation firm to measure the fair value of the liability. The valuation technique used to measure the fair value of the liability was a Monte Carlo simulation. The primary inputs included revenue forecast, risk free rate, revenue volatility, revenue discount rate and payment discount rate. We will review and assess the value of the liability on a quarterly basis. Adjustments, if any, will be included as a component of earnings in the consolidated statements of operations.

We recognize rental revenue in accordance with ASC Topic 842, Leases. In the event collectability of lease payments is not probable at the lease commencement date, we recognize revenue when payments are received. We regularly evaluate the collectability of our lease receivables on a lease-by-lease basis. The evaluation primarily consists of reviewing past due account balances and other factors such as the credit quality of the customer, historical trends of the customer and current economic conditions. We suspend the recognition of rental revenue when the collectability of amounts due are no longer probable and record a direct write-off of the lease receivable to rental revenue.

Recent Accounting Pronouncements

Please refer to Note 1 of our consolidated financial statements contained in this Annual Report on Form 10-K for a discussion of recent accounting pronouncements.

Management’s Current Outlook and Assumptions

Regarding our Energy Solutions business segment, demand for our products is subject to volatile fluctuations in crude oil prices. As a result of substantial declines in crude oil prices in recent years, oil and gas exploration and production companies experienced a significant reduction in cash flows resulting in sharp reductions in their capital spending budgets for oil and gas exploration-focused activities including seismic data acquisition activities. While we experienced stronger wireless land product sales in fiscal year 2025, the need for new seismic equipment, particularly traditional land-based equipment, remains restrained due to our customers’ (i) limited capital resources, (ii) lack of visibility into future demand for their seismic services and (iii) in some cases, under-utilized legacy equipment.

28

The vast majority of our Energy Solutions business segment revenue in fiscal year 2025 was derived from wireless product sales. We believe our wireless product sales will moderately increase in fiscal year 2026 over 2025 levels, primarily driven by our recent introduction of our PioneerTM land-based wireless system and our Mariner® wireless system, but we can make no assurance in this regard.

We expect that fiscal year 2026 revenue from our Energy Solutions reservoir products will increase significantly over fiscal year 2025 levels due to the PRM contract we entered into in the third quarter of 2025. The duration of the contract is expected to be approximately 18 months. Revenue will be recognized over the duration of the contract.

We expect fiscal year 2026 revenue from our Smart Water business segment products to increase slightly over fiscal year 2025 levels due in part to the continued increase in demand for our Hydroconn® products and growth in market acceptance in our Aquana products.

We expect fiscal year 2026 revenue from our Intelligent Industrial business segment products to increase over fiscal year 2025 levels due to our recent acquisition of Geovox's Heartbeat Detector® as well as optimism that demand for our surveillance and defense products and our contract manufacturing services will increase.

We are aggressively marketing our SADAR® technologies to both our security and oil and gas industry customers. While marked acceptance of SADAR® as an effective analytical tool for categorizing seismic data, we continue to believe acceptance will occur.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K, we conducted an evaluation, under supervision and with the participation of management, including the Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (Exchange Act). Based upon that evaluation, our CEO and CFO concluded that our disclosure controls and procedures are effective at a reasonable assurance level. Disclosure controls and procedures are defined by Rules 13a-15(e) and 15d-15(e) of the Exchange Act as controls and other procedures that are designed to ensure that information required to be disclosed by us in reports filed with the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports filed under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of September 30, 2025. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control Integrated Framework (2013). Based on this assessment, our management concluded that, as of September 30, 2025, our internal control over financial reporting is effective based on those criteria.

Our independent registered public accounting firm, RSM US LLP, has audited the effectiveness of our internal controls over financial reporting, as stated in their attestation report included in this Annual Report on Form 10-K.

29

Changes in Internal Control Over Financial Reporting

There have not been any other changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act) during the fiscal quarter ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Geospace Technologies Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Geospace Technologies Corporation and its subsidiaries (the Company) as of September 30, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the two years in the period ended September 30, 2025, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended September 30, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated November 21, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical AuditMatters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Inventory Valuation

As described in Note 1 to the financial statements, the Company’s carrying value of inventories, net, which is stated at lower of cost or net realizable value, was $48 million as of September 30, 2025. The valuation of inventories is based on the Company’s periodic review of the composition of its inventories to determine if market demand, product modifications, technology changes, excessive quantities on-hand and other factors hinder its ability to recover its investment in such inventories. The Company’s assessment is based upon historical product demand, estimated future product demand and various other judgments and estimates. Inventory obsolescence reserves are recorded when such assessments reveal that portions or components of the Company’s investment will not be realized in its operating activities.

We identified the valuation of inventories at the lower of cost or net realizable value as a critical audit matter due to the significant judgment and estimates required by management. Determining whether a decline in value has occurred requires management to make complex judgments related to (i) historical and estimated future product demand in relation to quantities on hand and (ii) obsolescence of certain products based on changes in technology and demand. Auditing these judgments is especially challenging and involved significant auditor judgment due to fluctuations in sales trends and evolving customer demands.

Our audit procedures related to the Company’s valuation of inventory included the following, among others:

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Geospace Technologies Corporation

Opinion on the Internal Control Over Financial Reporting

We have audited Geospace Technologies Corporation’s (the Company) internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements of the Company and our report dated November 21, 2025, expressed an unqualified opinion.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies

The Company

Geospace Technologies Corporation and its subsidiaries are referred to collectively as the “Company”. The Company designs and manufactures sophisticated technology solutions for applications in energy exploration, smart water management, as well as industrial and Internet of Things ("IoT"). The Company's seismic equipment and services are marketed to the energy exploration industry and used to locate, characterize and monitor hydrocarbon producing reservoirs. The Company also markets its seismic products to other industries for vibration monitoring, border and perimeter security and various geotechnical applications. The Company designs and manufacture other products of a non-seismic nature, including water meter connector cables, imaging equipment, remote shutoff water valves and ("IoT") platform. Additionally, the Company provides specialized contract manufacturing services. In recent years, the revenue contribution from our non-energy related products has grown to represent nearly half of our total revenue. Its business diversification strategy has centered largely on translating expertise in ruggedized engineering and technology manufacturing into expanded customer markets.

Basis of Presentation

The accompanying financial statements present the consolidated financial position, results of operations and cash flows of the Company in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). All significant intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company considers many factors in selecting appropriate operational and financial accounting policies and controls and in developing the estimates and assumptions that are used in the preparation of these financial statements. The Company continually evaluates its estimates, including those related to revenue recognition, credit loss, collectability of rental revenue, inventory obsolescence reserves, self-insurance reserves, product warranty reserves, useful lives of long-lived assets, impairment of long-lived assets, impairment of goodwill and other intangible assets and deferred income tax assets. The Company bases its estimates on historical experience and various other factors that are believed to be reasonable under the circumstances. While management believes current estimates are reasonable and appropriate, actual results may differ from these estimates under different conditions or assumptions.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original or remaining maturity at the time of purchase of three months or less to be cash equivalents. At September 30, 2025, cash and cash equivalents included $0.8 million held by the Company’s foreign subsidiaries and branch offices.

Concentrations of Risk

Credit

The Company maintains its cash in bank deposit accounts that, at times, exceed federally insured limits. Management of the Company believes that the financial strength of the financial institutions holding such deposits minimizes the credit risk of such deposits.

The Company sells products to customers throughout the United States and various foreign countries. The Company’s normal credit terms for trade receivables are 30 days. In certain situations, credit terms may be extended to 60 days or longer. The Company performs ongoing credit evaluations of its customers and generally does not require collateral for its trade receivables. Additionally, the Company provides long-term financing in the form of promissory notes and sales-type leases when competitive conditions require such financing. In such cases, the Company may require collateral. Allowances are recognized immediately for expected credit losses. The Company determines the allowance for credit losses through a review of several factors, including historical collection experience, customer credit worthiness, current aging of customer accounts and current financial conditions of its customers. Receivables are charged off against the allowance whenever it is probable that the balance will not be recoverable.

Two customers each comprised 19.1% and 16.2% of the Company’s revenue during fiscal year 2025. At September 30, 2025, the Company had trade accounts and financing receivables from these customers of $7.3 million and $2.2 million, respectively. Two customers each comprised 27.4% and 16.0% of the Company’s revenue during fiscal year 2024. At September 30, 2024, the Company had trade accounts and financing receivables from these customers of $4.1 million and $9.5 million, respectively.

Notes to Consolidated Financial Statements—(Continued)

Suppliers

The Company purchases certain electronic components used in its land and marine wireless nodes from two single source suppliers. In the event a change in one or both suppliers is necessary, significant engineering design efforts would be required by the Company.

The Company purchases all of its thermal film from one manufacturer for its imaging products. Except for the film sold to the Company by this manufacturer, the Company knows of no other source for thermal film that performs as well in its imaging equipment. If the manufacturer were to discontinue producing thermal film, were to become unwilling to contract with the Company on competitive terms or were unable to supply thermal film in sufficient quantities to meet its requirements, the Company’s ability to compete in the direct thermal imaging marketplace could be impaired, which could adversely affect its financial performance. Thermal film sales represented approximately 7% and 5% of the Company’s revenue for fiscal years 2025 and 2024, respectively.

Short-term Investments

The Company classifies its short-term investments as available-for-sale debt securities which have maturities of less than one year. These securities are carried at fair market value with net unrealized gains and losses reported as a component of accumulated other comprehensive loss in stockholders’ equity. Credit losses are recorded as an allowance rather than a reduction of the amortized cost basis for debt securities determined to be impaired for which there is neither an intent nor a more-likely-than-not requirement to sell. Reversals of credit losses are recorded in current period income as they occur. The Company had no short-term investments at September 30, 2025.

Inventories

The Company records a write-down of its inventories when the cost basis of any manufactured product, including any estimated future costs to complete the manufacturing process, exceeds its net realizable value. Inventories are stated at the lower of cost or net realizable value. Cost is determined on the first-in, first-out method, except that certain of the Company’s foreign subsidiaries use an average cost method to value their inventories.

The Company periodically reviews the composition of its inventories to determine if market demand, product modifications, technology changes, excessive quantities on-hand and other factors hinder our ability to recover its investment in such inventories. The Company’s assessment is based upon historical product demand, estimated future product demand and various other judgments and estimates. Inventory obsolescence reserves are recorded when such assessments reveal that portions or components of the Company’s inventory investment will not be realized in its operating activities.

The Company reviews its inventories for classification purposes. The value of inventories not expected to be realized in cash, sold or consumed during its next operating cycle are classified as non-current assets.

Notes to Consolidated Financial Statements—(Continued)

Property, Plant and Equipment and Rental Equipment

Property, plant and equipment and rental equipment are stated at cost. Depreciation expense is calculated using the straight-line method over the following estimated useful lives:

Years

Rental equipment 2 - 5

Property, plant and equipment:

Machinery and equipment 3 - 15

Buildings and building improvements 10 - 50

Expenditures for renewals and betterments are capitalized. Repairs and maintenance expenditures are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and any gain or loss thereon is reflected in the statements of operations.

Business Acquisitions

The Company accounts for its business acquisitions under the acquisition method of accounting. The total value of the consideration paid for acquisitions is allocated to the underlying net assets acquired, based on their respective estimated fair values. The Company uses a number of valuation methods to determine the fair value of assets and liabilities acquired, including discounted cash flows, external market values, valuations on recent transactions or a combination thereof, and believes that it uses the most appropriate measure or a combination of measures to value each asset or liability. The Company utilized the excess earnings method to value its fourth quarter fiscal year 2025 acquisition of Geovox Securities, Inc. ("Geovox"). The Company recognizes measurement-period adjustments in the reporting period in which the adjustment amounts are determined.

Contingent Consideration

The Company established an earn-out liability in connection with its acquisition of Geovox in the fourth quarter of fiscal year 2025. The Company engaged the services of a valuation firm to measure the fair value of the liability. The valuation technique used to measure the fair value of the liability was a Monte Carlo simulation. The primary inputs included revenue forcast, risk free rate, revenue volatility, revenue discount rate and payment discount rate. Company reviews and assesses the value of the liability on a quarterly basis. Adjustments, if any, will be included as a component of earnings in the consolidated statements of operations.

Impairment of Long-lived Assets

The Company’s long-lived assets are reviewed for impairment whenever an event or change in circumstances indicates the carrying amount of an asset or group of assets may not be recoverable. The impairment review, if necessary, includes a comparison of expected future cash flows (undiscounted and without interest charges) to be generated by an asset group with the associated carrying value of the related assets. If the carrying value of the asset group exceeds the expected future cash flows, an impairment loss is recognized to the extent that the carrying value of the asset group exceeds its fair value.

At September 30, 2024, in light of the Company's historical losses and continued delays in obtaining additional contracts from the U.S. Customs and Border Protection and other customers on its Emerging Markets segment (now a component of the Company's Intelligent Industrial segment), the Company performed a recoverability assessment on the long-lived assets of its Emerging Markets asset group in which its carrying value was compared to estimated undiscounted cash flows over the remaining useful life of the asset group's primary asset, which is its developed technology. The carrying value of the asset group was in excess of the estimated undiscounted future cash flows. Accordingly, a fair value analysis was performed. Based on the assessment, the Company determined the fair value of the asset was less than its carrying value. The Company used an excess earnings approach to value the asset. Key assumptions used in the analysis include revenue, gross margin and cash flow projections. As a result of the assessment, the Company recorded an impairment charge of $2.8 million on this asset group, which impaired its developed technology intangible asset in its entirety.

Goodwill

The Company conducts its evaluation of goodwill at the reporting unit level on an annual basis as of September 30 and more frequently if events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value. The Company first assesses qualitative factors to determine if the fair value of a reporting unit exceeds its carrying amount. If, based on the qualitative assessment of events or circumstances, the Company determines it is more likely than not that the fair value of a reporting unit is more than its carrying amount then it does not perform a quantitative assessment. However, if the Company concludes otherwise, then it performs a quantitative assessment. If, based on the quantitative assessment, the Company determines that the fair value of a reporting unit is less that its carrying amount, a goodwill impairment is recognized equal to the difference between the carrying amount of the reporting unit and its fair value, not to exceed the carrying amount of the goodwill.

Notes to Consolidated Financial Statements—(Continued)

Other Intangible Assets

Intangible assets are carried at cost, net of accumulated amortization. The estimated useful life of the Company’s other intangible assets are evaluated each reporting period to determine whether events or circumstances warrant a revision to the remaining amortization period. If the estimate of an intangible asset’s remaining useful life is changed, the amortization period should be changed prospectively. Amortization expense is calculated using the straight-line method over the following estimated useful lives:

Years

Developed technology 10 - 18

Trade names 5

Customer relationships 4

Non-compete agreements 4

Revenue Recognition

See Note 2 to these consolidated financial statements.

Research and Development Costs

The Company expenses research and development costs as incurred. Research and development costs include salaries, employee benefit costs, department supplies, direct project costs and other related costs.

Product Warranties

Most of the Company’s products do not require installation assistance or sophisticated instructions. The Company offers a standard product warranty obligating it to repair or replace equipment with manufacturing defects. The Company maintains a reserve for future warranty costs based on historical experience or, in the absence of historical product experience, management’s estimates. Reserves for future warranty costs are included within other current liabilities on the consolidated balance sheets.

Changes in the product warranty reserve are reflected in the following table (in thousands):

Accruals for warranties issued during the year 2,331

Settlements made (in cash or in kind) during the year (1,738 )

Accruals for warranties issued during the year 1,365

Settlements made (in cash or in kind) during the year (1,153 )

Stock-Based Compensation

The Company accounts for stock-based compensation, including grants of restricted awards and unqualified stock options in accordance with Accounting Standards Codification Topic 718, which requires that all share-based payments (to the extent that they are compensatory) be recognized as an expense in the Company’s consolidated statements of operations based on their fair values on the award date and the estimated number of shares it ultimately expects to vest.

The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period of the award. The Company’s stock-based compensation plan and awards are more fully described in Note 16 to these consolidated financial statements.

F-

13

Geospace Technologies Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

Foreign Currency Gains and Losses

The assets and liabilities of the Company’s foreign subsidiaries and branch offices that have a foreign currency as their functional currency have been translated into U.S. dollars using the exchange rates in effect at the balance sheet date. Results of operations have been translated using the average exchange rates during the year. Resulting translation adjustments have been recorded as a component of accumulated other comprehensive losses in stockholders’ equity. Foreign currency transaction gains and losses are included in the statements of operations as they occur. Transaction gains and losses on intra-entity foreign currency transactions and balances, including advances and demand notes payable on which settlement is not planned or anticipated in the foreseeable future, are recorded in “accumulated other comprehensive loss” on our consolidated balance sheets.

Fair Value

Fair value is the price that would be received to sell an asset or the amount paid to transfer a liability in an orderly transaction between market participants (an exit price) at the measurement date. U.S. GAAP has established a fair value hierarchy which prioritizes the inputs to the valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement. Level 1 represents unadjusted quoted prices in active markets for identical assets and liabilities. Level 2 represents quoted prices for similar assets and liabilities in active markets (other than those included in Level 1) which are observable, either directly or indirectly. Level 3 represents valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Also see Note 6 to these consolidated financial statements.

Income Taxes

Income taxes are presented in accordance with the Accounting Standards Codification Topic 740 (“Topic 740”) guidance for accounting for income taxes. The estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, as well as operating loss and tax credit carrybacks and carryforwards are recorded. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities (temporary differences) and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company periodically reviews the recoverability of tax assets recorded on the balance sheet and provides valuation allowances if it is more likely than not that such assets will not be realized.

The Company follows the guidance of Topic 740 to analyze all tax positions that are less than certain. Topic 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In accordance with Topic 740, the Company recognizes in its financial statements the impact of a tax position if that position is “more likely than not” to be sustained on audit, based on the technical merits of the position. The Company’s estimate of the potential outcome of any uncertain tax issue is subject to management’s assessment of relevant risks, facts, and circumstances existing at that time. The Company classifies interest and penalties associated with the payment of income taxes, if any, in the Other Income (Expense) section of its consolidated statements of operations.

Recently Adopted Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (the "FASB") issued guidance which updates reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance shall be applied retrospectively to all prior periods presented in the financial statements. The Company adopted this guidance in the fourth quarter of fiscal year 2024 and is reflected in Note 21. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

Recently Issued Accounting Pronouncements

In November 2024, the FASB, as further amended in January 2025, issued guidance requiring enhanced disclosures in financial statements by requiring detailed disclosures of specific expenses like inventory purchases, employee compensation, depreciation, and intangible assets amortization. The guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 31, 2027. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In December 2023, the FASB issued guidance regarding improvements in income tax disclosure which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. The Company will adopt this guidance in its fourth quarter of fiscal year 2026. The guidance allows for adoption using either a prospective or retrospective transition method. The adoption of this guidance is not expected to have any material impact on its consolidated financial statements.

2. Revenue Recognition

In accordance with ASC Topic 606,Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenue when performances of contractual obligations are satisfied, generally when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services.

The Company primarily derives product revenue from the sale of its manufactured products. Revenue from these product sales, including the sale of used rental equipment, is recognized when obligations under the terms of a contract are satisfied, control is transferred and collectability of the sales price is probable. The Company records deferred revenue when customer funds are received prior to shipment or delivery or hen performance has not yet occurred. The Company assesses collectability during the contract assessment phase. In situations where collectability of the sales price is not probable, the Company recognizes revenue when it determines that collectability is probable or when non-refundable cash is received from its customers and there is not a significant right of return. Transfer of control generally occurs with shipment or delivery, depending on the terms of the underlying contract. The Company’s products are generally sold without any customer acceptance provisions, and the Company’s standard terms of sale do not allow customers to return products for credit.

Revenue from engineering services is recognized as services are rendered over the duration of a project, or as billed on a per hour basis. Field service revenue is recognized when services are rendered and is generally priced on a per day rate.

The Company also generates revenue from short-term rentals under operating leases of its manufactured products. Rentals of the Company’s equipment generally range from daily rentals to minimum rental periods of up to one year. Rental revenue is recognized within the scope of ASC 842,Leases ("ASC 842"). The Company regularly evaluates the collectability of its lease receivables on a lease-by-lease basis. The evaluation primarily consists of reviewing past due account balances and other factors such as the credit quality of the customer, historical trends of the customer and current economic conditions. In accordance with ASC 842, rental revenue is recognized as earned over the rental period if collectability of the rent is reasonably assured. When collectability of amounts are no longer probable the Company records a direct write-off of the rent receivable to rental revenue and limits future rental revenue recognition to cash received. During the second quarter of fiscal year 2025, the Company determined that the collectability of receivables from a rental customer was less than probable. As a result of this determination, the rent receivable balance due from this customer of $2.2 million was reversed against rental revenue. Any future cash received from this customer will be recognized as rental revenue.

As permissible under ASC 606, sales taxes and transaction-based taxes are excluded from revenue. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Additionally, the Company expenses costs incurred to obtain contracts when incurred because the amortization period would have been one year or less. These costs are recorded in selling, general and administrative expenses.

The Company has elected to treat shipping and handling activities in a sales transaction after the customer obtains control of the goods as a fulfillment cost and not as a promised service. Accordingly, fulfillment costs related to the shipping and handling of goods are accrued at the time of shipment. Amounts billed to a customer in a sales transaction related to reimbursable shipping and handling costs are included in revenue, and the associated costs incurred by the Company for reimbursable shipping and handling expenses are reported in cost of revenue. The Company incurred shipping and handling expenses of $0.3 million for each of the fiscal years ended September 30, 2025 and 2024, respectively.

At September 30, 2025 and 2024, the Company had no deferred contract liabilities and no deferred contract costs. At October 1, 2023, the Company had deferred contract liabilities of $0.7 million and no deferred contract costs. For the fiscal years ended September 30, 2025 and 2024, revenue of zero and $0.7 million, respectively, was recognized from deferred contract liabilities. For each of the fiscal years ended September 30, 2025 and 2024,no cost of revenue was recognized from deferred contract costs. At September 30, 2025, October 1, 2024 and October 1, 2023, the Company had accounts receivable from contracts with customers of $11.4 million, $12.6 million and $11.2 million, respectively. Accounts receivable from contracts with customers excludes accounts receivable from rental contracts.

For the fiscal years ended September 30, 2025 and 2024, revenue of $1.8 million and $1.3 million, respectively, was recognized from contracts with customers satisfied over-time. Revenue satisfied over-time for the fiscal year ended September 30, 2025 was from the Company's Energy Solutions operating segment. Revenue satisfied over-time for the fiscal year ended September 30, 2024 was from the Company's Intelligent Industrial operating segment. All other revenue from contracts with customers for the fiscal years ended September 30, 2025 and 2024 was recognized at a point-in-time.

At September 30,2025, the aggregate amount of transaction price allocation to unsatisfied performance obligations on contracts with a duration in excess of one year was approximately $92 million. These unsatisfied performance obligations are expected to be fulfilled over the next 18 months. The majority of the revenue will be recognized over-time over the duration of the contracts. All other revenue from contracts with customers is being recognized at a point-in time and have a duration of one year or less.

3. Business Acquisition

On August 1, 2025, the Company acquired all the outstanding stock of Geovox. Geovox's Heartbeat Detector® is a heartbeat detection security technology developed by the United States Department of Energy’s Oak Ridge National Laboratory. It is used in more than a dozen countries to address human trafficking and prison security. The Heartbeat Detector® uses proprietary sensors to rapidly identify people hidden in vehicles, providing a modern, user-friendly interface in as little as 10 seconds. The Heartbeat Detector® relies on geophones the Company manufactures and aligns with the Company's current perimeter security and surveillance offerings in its Intelligent Industrial segment.

The Geovox acquisition was accounted for under the acquisition method of accounting. The total value of the consideration paid for acquisitions was allocated to the underlying net assets acquired, based on their respective estimated fair values. The Company utilized the excess earnings method to determine the fair value of assets and liabilities acquired, including discounted cash flows, external market values, valuations on recent transactions or a combination thereof, and believes that it used the most appropriate measure to value each asset or liability. The Company will recognize measurement-period adjustments, if any, in the reporting period in which the adjustment amount is determined.

The acquisition purchase price for Geovox consisted of (i) cash of $1.7 million, which included $1.5 million paid at closing and $0.2 million to be paid June 1, 2027, and (ii) contingent earn-out payments of up to $3.3 million over a four-year period. The contingent payments, if any, will be derived from certain eligible revenue that may be generated during the four-year period. In connection with the acquisition the Company recorded goodwill of $0.5 million, other intangible assets of $3.7 million, and an initial contingent earn-out liability of $2.5 million. Also see Notes 6 and 12.

Legal and professional costs of $35,000 related to the acquisition are included in selling, general and administrative expenses for the fiscal year ended September 30, 2025.

4. Sale of Subsidiary

On August 30, 2024, the Company sold its oil and gas product manufacturing operations based in the Russian Federation. The sale was consummated pursuant to a stock purchase agreement between the Company and a group of former employees based in the Russian Federation ("the Buyer"). Consideration to the Company consisted of a $1.0 million cash payment due from the buyer within 90 days of the sale and a $3.5 million promissory note. The note is for a 10-year term and bears interest at 5% per annum. Principal and interest installments of $37,000 are due monthly. The Company recorded a loss on sale in connection with the transaction of $14.5 million, of which $13.1 million was related to the impact of cumulative foreign currency translation losses previously included in accumulated comprehensive loss. Based on a fair value analysis performed on the promissory note as of the sale date, the Company recorded a $0.9 million discount to fair value on the note receivable. The note receivable is included as components of current and non-current trade accounts and financing receivables, net, on the consolidated balance sheet as of September 30, 2024. The sale did not have a material effect on the Company's consolidated net assets and is not expected to have a material effect on the Company's future revenue, profits or losses. Also see Note 6.

The Company has determined that the Buyer's legal entity is a variable interest entity ("VIE") due to the nature of the financing for the transaction. A VIE is an entity in which equity investors lack the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. VIEs are consolidated by the primary beneficiary, which is the party who has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and who has an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity. The Company determines whether it is the primary beneficiary of a VIE upon initial involvement with a VIE and reassesses whether it is the primary beneficiary of a VIE on an ongoing basis. The determination of whether an entity is a VIE and whether it is primary beneficiary of a VIE is based upon the facts and circumstances for the VIE and requires significant judgments such as whether the entity's interest in a VIE is a variable interest, whether it controls the activities that most significantly impact the economic performance of the VIE, and whether it has the obligation to absorb losses or the right to receive benefits of the VIE that could be significant to the VIE. A VIE is consolidated if management determines it is the primary beneficiary of the VIE.

While the debt represents a direct obligation to absorb significant losses of the VIE, the debt does not establish the right and power to direct activities that most significantly impact the economic performance of the entity. The Company retained no equity or voting interest, has no employees that are directors or advisors of the new ownership group, and has no direct influence on the day-to-day decisions in operations or affects on the VIE's ability to generate profits or losses. As such, the Company has determined it is not the primary beneficiary of the VIE. The Company's maximum exposure to loss at September 30, 2025 due to its involvement with the VIE is the carrying value of our note receivable from the sale of our former subsidiary, which was $3.2 million.

5. Short-term Investments

The Company classifies its short-term investments as available-for-sale debt securities. These securities are carried at fair market value with net unrealized gains and losses reported as a component of accumulated other comprehensive loss in stockholders’ equity. The Company had no short-term investments as of September 30, 2025. The Company’s short-term investments as of September 30, 2024 were composed of the following (in thousands):

Amortized Cost Unrealized Gains Unrealized Losses Estimated Fair Value

Short-term investments:

At September 30, 2024, accrued interest receivable related to these short-term investments was $0.3 million, which is included as a component of prepaid expenses and other current assets.

The Company has no debt securities in a material unrealized loss position at September 30, 2024 and does not believe the unrealized losses associated with these debt securities represent credit losses based on the evaluation of evidence, which includes an assessment of whether it is more likely than not it will be required to sell or intend to sell the investment before recovery of the investments amortized cost basis. A gain of $9,000 was realized from the sale of short-term investments for the fiscal year ended September 30, 2025. No gains or losses were realized from the sale of short-term investments for the fiscal year ended September 30, 2024.

6. Fair Value of Financial Instruments

The Company’s financial instruments generally include cash and cash equivalents, short-term investments, trade accounts and financing receivables and accounts payable. Due to the short-term maturities of cash and cash equivalents, trade accounts receivable and accounts payable, the carrying amounts approximate fair value on the respective balance sheet dates.

The Company measures its contingent consideration and short-term investments at fair value on a recurring basis.

The following tables present the fair value of the Company’s continent consideration, short-term investments and note receivable on sale of subsidiary by valuation hierarchy and input (in thousands):

Assets and Liabilities Measured on a Nonrecurring Basis

The Company performed a fair value analysis of the $3.5 million promissory note obtained in connection with its subsidiary sale as of the August 2024 transaction date. The measurements utilized to determine the implied fair value of the note receivable obtained represented significant unobservable inputs (Level 3). The derivation of discount rate utilized in the analysis was based on comparable market yields. Based on the analysis, the Company recorded a $0.9 million discount to fair value on this note receivable. Also see Note 4 to these consolidated financial statements.

At September 30, 2024, the Company performed a recoverability assessment on its long-lived assets of its Intelligent Industrial asset group (formerly Emerging Markets) in which its carrying value was compared to the estimated undiscounted cash flows over the remaining useful life of the asset group's primary asset, which is its developed technology. Accordingly, a fair value analysis was performed. Based on the assessment, the Company determined the fair value of the asset was less than its carrying value and recorded an impairment charge of $2.8 million on this asset group, which impaired its intangible assets in their entirety. The Company determined the fair value of this asset group to be approximately zero. The measurements utilized to determine the implied fair value represented significant unobservable inputs (Level 3). See Note 12 for more information.

In connection with the Company's acquisition of Geovox in August 2025, it recorded an initial contingent earn-out liability of $2.5 million. The Company engaged the services of a valuation firm to measure the fair value of the liability. The primary inputs included revenue forcast, risk free rate, revenue volatility, revenue discount rate and payment discount rate (Level 3). Contingent payments, if any, will be based on eligible revenue generated during a four-year earn-out period. The maximum amount of contingent payments is $3.3 million. The following table summarizes the changes in the fair value of the contingent consideration for the fiscal year September 30, 2025:

Balance at October 1, 2024 $ —

Contingent consideration pursuant to acquisition 2,540
