**GEOSPACE TECHNOLOGIES CORPORATION AND SUBSIDIARIES**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)**

***1.* Significant Accounting Policies**

*Basis of Presentation*

The consolidated balance sheet of Geospace Technologies Corporation and its subsidiaries (the "Company") at *September 30, 2025*, was derived from the Company's audited consolidated financial statements at that date. The consolidated balance sheet at *March 31, 2026* and the consolidated statements of operations, comprehensive loss, stockholders' equity and cash flows for the *three* and *six* months ended *March 31, 2026* and *2025* were prepared by the Company without audit. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the consolidated financial position, results of operations and cash flows were made. All significant intercompany balances and transactions have been eliminated. The results of operations for the *three* and *six* months ended *March 31, 2026*, are *not* necessarily indicative of the operating results for a full year or of future operations.

Certain information and footnote disclosures normally included in financial statements presented in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") were omitted pursuant to the rules of the Securities and Exchange Commission. The accompanying consolidated financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company's Annual Report on Form *10*-K for the Company's fiscal year ended *September 30, 2025*.

*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, contingent consideration 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.

*Reclassifications*

Certain amounts previously reported in the consolidated financial statements have been reclassified to conform to the current year presentation. Such reclassifications had *no* effect on our previously reported net loss, stockholders' equity or cash flows.

*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 *March 31, 2026* and *September 30, 2025*, cash and cash equivalents included $0.6 million and $0.8 million, respectively, held by the Company's foreign subsidiaries and branch offices.

*Concentration of Credit Risk*

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, and current aging of customer accounts and financial conditions of its customers. Receivables are charged off against the allowance whenever it is probable that the balance will *not* be recoverable.

The Company had trade accounts and notes receivable from two customers of $15.5 million and $5.9 million, respectively at *March 31, 2026*. The Company recognized revenue from these two customers of $3.6 million and $27,000, respectively, for the *three* months ended *March 31, 2026,* and revenue of $14.2 million and $49,000, respectively, for the *six* months ended *March 31, 2026*. The Company recognized revenue from these two customers of zero and $44,000, respectively, for the *three* months ended *March 31, 2025,* and revenue of zero and $0.1 million, respectively, for the *six* months ended *March 31, 2025*. These receivables and revenue are related to the Company's Energy Solutions segment.

*Impairment of Long-lived Assets*

The Company's long-lived assets are reviewed for impairment whenever an event or circumstance indicates that the carrying amount of an asset or group of assets *may not* be recoverable. The impairment review, if necessary, includes a comparison of the 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. During the quarter ended *March 31, 2026*, *no* events or changes in circumstances were identified indicating the carrying value of any of the Company's asset groups *may not* be recoverable.

*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.

*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 multiple 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 forecast, risk free rate, revenue volatility, revenue discount rate and payment discount rate. The 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.

*Research and Development*

We incur significant future research and development expenditures. These efforts are primarily aimed at the development of additional products for each of our business segments. The majority of our product research and development costs relates to the Company's engineers. The Company's engineering staff have been key to our past success. Research and development expense includes personnel costs of the Company's engineers, project expenditures, on-going product maintenance and improvements to our existing products, as well as general and administrative expenses associated with the engineering department. Research and development expense for the *three* and *six* months ended *March 31, 2026* was $4.8 million and $9.3 million, respectively. Research and development expense for the *three* and *six* months ended *March 31, 2025* was $5.2 million and $10.1 million, respectively.

*Recently Issued Accounting Pronouncements*

In *November 2024,* the Financial Accounting Standards Board ("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 asset amortization. The guidance is effective for fiscal years beginning after *December 15, 2026,* and interim periods within fiscal years beginning after *December 15, 2027.* Early adoption is permitted. The Company is currently evaluating the provisions of this guidance and the impact on its consolidated financial statements.

In *December 2023,* the FASB issued guidance improvements on 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.

All other new accounting pronouncements that have been issued, but are *not* yet effective, are currently being evaluated and at this time are *not* expected to have a material impact on the Company's financial position or results of operations.

***2.* Revenue Recognition**

In accordance with ASC Topic *606, Revenue from Contracts with Customers* ("ASC *606"*), the Company recognizes revenue when performance 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 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.

The Company occasionally recognizes revenue from contracts throughout the manufacturing or service process, even prior to delivery of the completed product or service to the customer. This overtime recognition of revenue requires that either (i) the customer simultaneously receives and consumes the economic benefits the Company provides, (ii) the Company creates or enhances an asset controlled by the customer or (iii) the Company's performance does *not* create an asset for which the it has an alternative use and has an enforceable right to payment for performance completed to date.

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.

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 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 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.

At *March 31, 2026* and *September 30, 2025*, the Company had deferred contract liabilities of $13.0 million and zero, respectively. At *March 31, 2026* and *September 30, 2025*, the Company had no deferred contract assets. During the *three* and *six* months ended *March 31, 2026* and *2025, no* revenue or cost of revenue was recognized from deferred contract costs or deferred contract asset. At *March 31, 2026* and *October 1, 2025,* the Company had accounts receivable from contracts with customers of $5.3 million and $11.4 million, respectively. At *March 31, 2025* and *October 1, 2024,* the Company had accounts receivable from contracts with customers of $13.2 million and $12.6 million, respectively. Accounts receivable from contracts with customers exclude accounts receivable from rental contracts.

For the *three* and *six* months ended *March 31, 2026* revenue of $3.6 million and $4.0 million, respectively, was recognized from contracts with customers satisfied over-time, which was from the Company's Energy Solutions segment. For the *three* and *six* months ended *March 31, 2025* no revenue was recognized from contracts with customers satisfied over-time.

At *March 31, 2026*, the aggregate amount of transaction price allocation to unsatisfied performance obligations on contracts with a duration in excess of *one* year was approximately $89 million. The majority of these unsatisfied performance obligations are expected to be fulfilled by the *third* quarter of fiscal year *2027.* Revenue from these contracts are expected to be recognized over-time utilizing the cost-to-cost method. All other revenue from contracts with customers are being recognized at a point-in time and have a duration of *one* year or less. For each of the Company's operating segments, the following table presents revenue (in thousands) only from the sale of products and the performance of services under contracts with customers. Therefore, the table excludes all revenue earned from rental contracts.

***11.* Commitments and Contingencies**

*Contingent Compensation Costs*

In *August 2025,* the Company acquired Geovox. In connection with the acquisition, the Company 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,* the Company acquired Aquana, LLC ("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.

*Legal Proceedings*

The Company is involved in various pending legal actions in the ordinary course of its business. Management is unable to predict the ultimate outcome of these actions, because of the inherent uncertainty of such actions. However, management believes that the most probable, ultimate resolution of current pending matters will *not* have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows.

The Company defines its segments as those operations our chief operating decision maker ("CODM") regularly reviews to analyze performance and allocate resources. The Company's CODM is the Chief Executive Officer. The CODM regularly reviews revenue, gross profit, operating expenses and operating income (loss) by segment as the primary measures of segment performance. The CODM reviews revenue as a primary indicator of operational performance, assessing how much revenue is brought in from core business activities, which reflects demand and execution of each segment's strategy. Gross profit, is reviewed by the CODM as a diagnostic metric and is particularly useful in evaluating margin trends. Operating income is the key profitability metric used to assess performance across segments and make decisions related to resource allocation, including capital expenditures, headcount, and other investment initiatives. Each of these metrics are considered in budgeting, forecasting, and operational planning decisions.

For financial reporting purposes, we are organized into these reportable segments and "Corporate", which includes the remainder of our businesses. The following table summarizes the Company's segment information (in thousands).

**Overview**

Unless otherwise specified, the discussion in this Quarterly Report on Form 10-Q refers to Geospace Technologies Corporation and its subsidiaries. We design and manufacture sophisticated technology solutions for applications in smart water management and energy exploration. Our seismic equipment and services are marketed to the energy exploration industry and used 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 other products of a non-seismic nature, including Hydroconn® connector cables, imaging equipment, remote shutoff water valves and Internet of Things ("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. Our business diversification strategy has centered largely on translating expertise in ruggedized engineering and technology manufacturing into expanded customer markets.

**Products and Product Development**

**Smart Water**

Our Smart Water segment emphasizes our targeted approach to growing its footprint in the water management industry. This business segment contains the highly successful Hydroconn® smart water connectivity offerings along with the Aquana products.

The adoption of advanced technology in water management has been bolstered by U.S. Federal funding programs such as Water Infrastructure Finance Act funding, which provides $7.5 billion for water-related infrastructure projects.

Over the last decade, we have seen a significant increase in sales volume of our Hydroconn® connector cables used in Automated Meter Reading (AMR) applications. These cables play a role in Advanced Metering Infrastructure (AMI) by enabling remote collection of usage data from utility meters, thereby eliminating the need for manual meter reading.

Our remote disconnect valves and water IoT platform allows customers that manage multi-family and commercial properties to monitor their properties for leak and burst events, with real-time notifications, complimented with our remote-shut off to stop water damage. These products also allow water utilities to re-claim non-revenue water at a lower energy and field service cost through remote control of water service without placing their employees in potential harm or danger.

**Energy Solutions**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our Energy Solutions business segment has historically accounted for the majority of our revenue. Geoscientists use seismic data primarily in connection with the exploration, development and production of oil and gas reserves to map potential and known hydrocarbon bearing formations and the geologic structures that surround them. This segment's products include wireless seismic data acquisition systems, reservoir characterization products and services, and traditional seismic exploration products such as geophones, hydrophones, leader wire, connectors, cables and various other seismic products. We believe our Energy Solutions products are among the most technologically advanced instruments and equipment available for seismic data acquisition.

Our seismic sensor, cable and connector products are compatible with most major competitive seismic data acquisition systems currently in use. Revenue from these products results primarily from seismic contractors purchasing our products as components of new seismic data acquisition systems or to repair and replace components of seismic data acquisition systems already in use.

We have developed multiple versions of a land-based wireless (or nodal) seismic data acquisition system including our most recent launch of the Pioneer™, an ultralight wireless sensor product. We believe our wireless sensor systems allow our customers to operate more effectively and efficiently because of their reduced environmental impact, lower weight, ease of operation and fewer maintenance requirements.

We have also developed an ocean bottom seismic data acquisition system called the OBX, and recently released Mariner® and Mariner Deep®. Similar to our land-based wireless systems, these ocean bottom systems may be deployed in virtually unlimited channel configurations and do not require interconnecting cables between each station. The Mariner® is a continuous, cable-free, four channel autonomous, shallow water ocean bottom recorder. Mariner™ is the next generation node designed for extended duration seabed ocean bottom seismic data acquisition. The slim profile nodes, which are part of our shallow water stations, are ideally deployed as deep as 750 meters. The device continuously records for up to 70 days and offers more rapid recharging times. Its slim profile creates space savings on seismic survey vessels, allowing contractors to fit up to 25% more nodes into a download/charge container. Mariner Deep® is a deepwater, wireless seismic acquisition node capable of operating for 200 days in water as deep as 3,450 meters.

Additionally, we have developed high-definition permanent reservoir monitoring systems ("PRM") for land and ocean-bottom applications in producing oil and gas fields. Our primary offering, OptoSeis® fiber optic sensing technology, provides high-definition seismic data acquisition systems with a flexible architecture, allowing them to be configured as a subsurface system for both land and marine reservoir-monitoring projects.

We also have a derivative of the OptoSeis® technology for high temperature downhole applications. The product, known as Insight by OptoSeis, offers a passive, all-optical downhole sensor network - no electronics downhole - resulting a year's long operational lifetime at 150°C.

We also produce seismic borehole acquisition systems that employ a fiber optic augmented wireline capable of very high data transmission rates. These systems are used for several reservoir monitoring applications, including an application pioneered by us allowing operators and service companies to monitor and measure the results of hydraulic fracturing operations.

Our SADAR® technology provides energy companies real-time monitoring of seismic data.

**Intelligent Industrial**

Our Intelligent Industrial segment consists of industrial sensors, electronic pre-press solutions and specialized contract manufacturing. The growing defense and security applications offered by Quantum and Heartbeat Detector® will also be reflected in this segment.

Our robust manufacturing capabilities have allowed us to provide specialized contract manufacturing services for printed circuit board manufacturing, cabling and harnesses, machining, injection molding and electronic system assembly.

Our seismic sensors provide unique high definition, low frequency sensing that allows for vibration monitoring in industrial machinery, mine safety and earthquake detection.

*Imaging Products*

Our imaging products include electronic pre-press products that employ direct thermal imaging, direct-to-screen printing systems, and digital inkjet printing technologies targeted at the commercial graphics, industrial graphics, textile and flexographic printing industries.

*Defense and Security*

Our Quantum product line includes SADAR®, a proprietary detection system which detects, locates and tracks items of interest in real-time. Using the SADAR® technology, Quantum designs and sells products used for border and perimeter security surveillance, cross-border tunneling detection and other products targeted at movement monitoring, intrusion detection and situational awareness. Quantum's customers include various agencies of the U.S. government including the Department of Defense, Department of Energy, Department of Homeland Security and other agencies.

In August 2025, we acquired Heartbeat Detector® by purchasing all of the outstanding common stock of Geovox. Heartbeat Detector® is a heartbeat detection security technology developed by the United States Department of Energy's Oak Ridge National Laboratory which bolsters our perimeter security and surveillance offerings. 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 product, which relies on geophones we manufacture, has been proven 99% effective by Oak Ridge, Sandia and Thunder Mountain national laboratories.

**Business Overview**

Our Smart Water segment has experienced a decline in sales in fiscal year 2026, however we believe this decline is temporary, largely due to overstocking by our customers in the prior fiscal year. 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 has seen a shift from rentals of our ocean bottom nodes to purchases of the equipment since fiscal year 2024. 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 Company began production of the PRM in the second quarter of 2026. The majority of the revenue from this contract is expected to be completed by the third quarter of fiscal year 2027. Revenue from this contract is being 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.

*Three and six months ended March 31, 2026 compared to the three and six months ended March 31, 2025*

Consolidated revenue for the three months ended March 31, 2026, was $19.7 million, an increase of $1.7 million, or 9.5%, from the corresponding period of the prior fiscal year. The increase for the three months ended March 31, 2026 was primarily due to higher revenue from our Energy Solutions segment, which included initial revenue of $3.6 million recognized on our PRM contract. The increase was largely offset by lower demand for our Hydroconn® cable and connector products from our Smart Water segment. Furthermore, during the second quarter of the prior fiscal year, we determined the collectability of a receivable from an ocean bottom 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. As a result of reversal, our consolidated rental revenue for the three months ended March 31, 2025 was in a negative position ($0.7 million). Consolidated revenue for the six months ended March 31, 2026, was $45.3 million, a decrease of $9.9 million, or 18.0%, from the corresponding period of the prior fiscal year. The decrease for the six months ended March 31, 2026 was primarily due to lower demand for our Hydroconn® cable and connector products from our Smart Water segment. The decrease in consolidated revenue was also due to lower revenue from our Energy Solutions segment attributable to a $17 million sale of ocean bottom nodes in the first quarter of fiscal year 2025, which was largely offset by an increase in demand for our wireless land-based Pioneer™.

Consolidated gross profit for the three months ended March 31, 2026, was $0.7 million, compared to $1.7 million from the corresponding period of the prior fiscal year. The decrease for the three months ended March 31, 2026 was primarily due to the decrease in revenue and related gross profits from our Smart Water segment. Consolidated gross profit for the six months ended March 31, 2026, was $3.4 million, compared to $21.9 million from the corresponding period of the prior fiscal year. The decrease in gross profit for the six months ended March 31, 2026 was primarily due to (i) a high gross margin on our $17 million sale of ocean bottom nodes in the first quarter of fiscal year 2025 and (ii) the decrease in revenue and gross profits from our Smart Water segment. The decrease in gross profit for both three and six months ended March 31, 2026 was also attributable to an increase in tariffs on the raw materials we purchase.

Consolidated operating expenses for the three months ended March 31, 2026, were $12.1 million, an increase of $0.1 million, or 0.7%, from the corresponding period of the prior fiscal year. Consolidated operating expenses for the six months ended March 31, 2026, were $25.1 million, an increase of $0.7 million, or 2.9% from the corresponding period of the prior fiscal year. The increase for both periods was primarily due to (i) an increase in sales and marketing costs, (ii) higher professional fees and (iii) severance costs. The increase in operating expenses six months ended March 31, 2026 was partially offset by a decrease in research and development expenses, primarily personnel costs and project expenditures.

Consolidated other income was unchanged for the three months ended March 31, 2026 and 2025. Consolidated other income for the six months ended March 31, 2026, decreased $0.1 million, or 8.8% from the corresponding period of the prior fiscal year. The decrease was principally due to (i) a decrease in interest income on short-term investments and (ii) a decrease in foreign exchange transaction losses.

**Segment Results of Operations**

**Smart Water**

*Revenue*

Revenue from our Smart Water segment for the three months ended March 31, 2026, decreased $5.7 million, or 60.6%, from the corresponding period of the prior fiscal year. Revenue from our Smart Water segment for the six months ended March 31, 2026, decreased $7.3 million, or 43.4%, from the corresponding period of the prior fiscal year. The decrease for both periods was primarily due to a decrease in demand for our Hydroconn® cable and connector products. We believe this decline is temporary due to overstocking by our customers in the prior fiscal year.

*Operating Income (Loss)*

Operating loss from our Smart Water segment for the three months ended March 31, 2026, was $(1.6) million, in comparison to operating income of $1.4 million from the corresponding period of the prior fiscal year. Operating loss from our Smart Water segment for the six months ended March 31, 2026, was $(2.4) million, in comparison to operating income of $1.8 million from the corresponding period of the prior fiscal year. The decrease for both periods was primarily due the decrease in revenue and related gross profits. The decrease for the six months ended March 31, 2026 was also attributable to higher research and development expense, largely personnel costs.

**Energy Solutions**

*Revenue*

Revenue from our Energy Solutions segment for the three months ended March 31, 2026, increased $7.0 million, or 272.1%, from the corresponding period of the prior fiscal year. Revenue from our Energy Solutions segment for the six months ended March 31, 2026, decreased $2.6 million, or 9.7%, from the corresponding period of the prior fiscal year. The components of this changes were as follows:

● *<u>Product Revenue</u>* – For the three months ended March 31, 2026, product revenue increased $5.6 million, or 164.1%, from the corresponding period of the prior fiscal year. The increase for the three months ended March 31, 2026 was primarily due (i) an increase in demand for our wireless land-based Pioneer™ and (ii) initial revenue of $3.6 million recognized on our PRM contract. For the six months ended March 31, 2026, product revenue decreased $0.7 million, or 2.9%, from the corresponding period of the prior fiscal year. Revenue for the six months ended March 31, 2025 included a $17 million sale of ocean bottom nodes. The decrease for the six months ended March 31, 2026 was partially offset by an increase in demand for our wireless land-based Pioneer™. 

● *<u>Rental Revenue</u>* – For the three months ended March 31, 2026, rental revenue from our ocean bottom nodes was $0.7 million, compared to a negative position ($0.8 million) for the corresponding period of the prior fiscal year. For the six months ended March 31, 2026, rental revenue from our ocean bottom nodes was $1.7 million, a decrease of $1.9 million, or 52.9%, in comparison to the corresponding period of the prior fiscal year. During the second quarter of the prior fiscal year, we determined the collectability of a receivable from an ocean bottom 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 during the three months ended March 31, 2025. The decrease in rental revenue for both periods was also due to lower utilization of our ocean bottom nodes rental fleet. 

*Operating Income (Loss)* 

Operating loss associated with our Energy Solutions segment for the three months ended March 31, 2026, was $(4.8) million, compared $(6.7) million for the corresponding period of the prior fiscal year. The decrease in operating loss was primarily due to the increase in revenue and related gross profits. Operating loss for the six months ended March 31, 2026, was $(8.2) million, compared to operating income of $6.6 million for the corresponding period of the prior fiscal year. This decrease was primarily attributable to the decrease in revenue, largely rental revenue, coupled by a high gross margin on our $17 million sale of ocean bottom nodes in the first quarter of fiscal year 2025.

**Intelligent Industrial**

*Revenue*

Revenue from our Intelligent Industrial segment for the three months ended March 31, 2026, increased $0.4 million, or 7.1%, from the corresponding period of the prior fiscal year. The increase was primarily due to an increase in demand for our contract manufacturing services. Revenue from our Intelligent Industrial segment for the six months ended March 31, 2026, decreased $0.1 million, or 0.4%, from the corresponding period of the prior fiscal year. The decrease in revenue for the six months ended March 31, 2026, was primarily due to a decrease in demand for our industrial sensor products, largely offset by increased demand for our contract manufacturing services.

*Operating Loss* 

Operating loss from our Intelligent Industrial segment for the three months ended March 31, 2026 decreased $0.7 million, or 54.4%, from the corresponding period of the prior fiscal year. The decrease in operating loss for the three months ended March 31, 2026 was primarily due to the increase in revenue and related gross profits. Operating loss for the six months ended March 31, 2026 decreased $0.8 million, or 37.1%, from the corresponding period of the prior fiscal year. The decrease in operating loss for the six months ended March 31, 2026 was primarily due to lower research and development expense, principally personnel costs.

**Liquidity and Capital Resources**

At March 31, 2026, we had $13.4 million in cash and cash equivalents. For the six months ended March 31, 2026, we used $16.7 million of cash from operating activities. Uses of cash included (i) our net loss of $20.8 million, offset by non-cash charges of $7.7 million resulting from deferred income taxes, depreciation, amortization, accretion, inventory obsolescence, stock-based compensation and provision for credit losses, a (ii) $2.8 million increase in inventories largely due to material purchases for use in our PRM contract, (iii) $2.4 million increase in notes receivable on product sales, (iv) $5.2 million decrease in trade accounts payable primarily due the timing of payments and (v) $2.6 million increase in other assets, primarily due to prepaid product purchases related to our PRM contract. These uses of cash were partially offset by a $9.1 million increase in other liabilities, primarily deferred contract liabilities related to our PRM contract.

For the six months ended March 31, 2026, we generated cash of $4.0 million in investing activities. Sources of cash included $6.9 million of proceeds from the sale of rental equipment, partially offset by $3.0 million used for additions to our property, plant and equipment. We do not expect significant cash investments in property, plant and equipment or our rental fleet for the remainder of fiscal year 2026.

For the six months ended March 31, 2026, we used $0.3 million from financing activities for tax payments on stock-based compensation for the exchange of common stock.

On August 29, 2025, we amended and restated 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, which includes cash and amounts available to borrow 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. Effective December 31, 2025, we entered into a limited waiver agreement with Woodforest which waived our springing minimum interest coverage ratio through February 16, 2027. At March 31, 2026 we were in compliance with all financial and non-financial covenants under the Agreement. We had no debt outstanding at March 31, 2026 and had a borrowing availability of $25 million.

On May 5, 2026, we entered into an amendment to our Agreement which removed the springing minimum interest coverage requirement. This amendment requires us to maintain a $2 million cash reserve pledged to Woodforest and is primarily secured by our Pinemont facility.

Our available cash and cash equivalents decreased $13 million during the first six months of fiscal year 2026, largely due to the decrease in revenue across all of our segments. At the end of the second quarter of fiscal year 2026 we implemented an organizational change plan, which included a voluntary early retirement plan available to eligible qualifying employees as well as a reduction in force. This plan will result in an approximate 20% reduction our global workforce, and together with cost-containment measures are expected to produce approximately $10 million of annualized cash savings. We anticipate receiving our next installment payment from our PRM customer of approximately $35 million by the end of the calendar year.

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 our backlog, 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, and amounts available under the Agreement if needed, 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.

**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, the Company acquired Aquana, LLC ("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 11 to our consolidated financial statements in this Quarterly Report on Form 10-Q for more information on our contractual contingencies.

**Critical Accounting Estimates**

During the six months ended March 31, 2026, there has been no material change to our critical accounting estimates discussed in Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 30, 2025.
