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, 2020 was derived from the Company’s audited consolidated financial statements at that date.  The consolidated balance sheet at March 31, 2021 and the consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for the three and six months ended March 31, 2021 and 2020 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 intercompany balances and transactions have been eliminated.  The results of operations for the three and six months ended March 31, 2021 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 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, 2020.

 Reclassifications

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

Use of 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.  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 bad debt reserves, collectability of rental revenue, inventory obsolescence reserves, self-insurance reserves, product warranty reserves, useful lives of long-lived assets, impairment of long-lived assets and intangible assets, contingent consideration, investment in debt security 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 March 31, 2021, cash and cash equivalents included $5.3 million held by the Company’s foreign subsidiaries and branch offices.  If the Company were to repatriate the cash held by its foreign subsidiaries, it could be required to accrue and pay taxes on any amount repatriated. The Tax Cut and Jobs Act (“2017 Tax Act”) creates new taxes on certain foreign earnings and also requires entities to pay a one-time transition tax on undistributed earnings of their foreign subsidiaries which were previously tax deferred.  The Company has determined it is not required to pay transition tax on the undistributed earnings of its foreign subsidiaries since it had no accumulated foreign earnings on a consolidated basis.

Recently Issued Accounting Pronouncements

 In June 2016, the Financial Accounting Standards Board (the “FASB”) issued guidance surrounding credit losses for financial instruments that replaces the incurred loss impairment methodology in generally accepted accounting principles.  The new impairment model requires immediate recognition of estimated credit losses expected to occur for most financial assets and certain other financial instruments.  For available-for-sale debt securities with unrealized losses, credit losses will be recognized as allowances rather than reductions in the amortized cost of the securities.  As a small reporting company, the Company must adopt this standard no later than the first quarter of its fiscal year ending September 30, 2024. Early adoption is permitted.  The standard’s provisions will be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting

8

period.  The Company intends to adopt this standard during the first quarter of its fiscal year ending September 30, 2024 and is continuing to evaluate the impact of this new guidance on its consolidated financial statements. 

In December 2019, the FASB issued guidance on simplifying the accounting for income taxes.  The guidance eliminates certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020.  Certain amendments within the guidance are required to be applied on a retrospective basis for all periods presented; others are to be applied using a modified retrospective approach with a cumulative-effect adjustment to retained earnings, if any, as of the beginning of the first reporting period in which the guidance is adopted; and yet others are to be applied using either basis. All other amendments not specified in the guidance should be applied on a prospective basis. Early adoption is permitted. An entity that elects to early adopt in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. The Company intends to adopt this standard during the first quarter of its fiscal year ending September 30, 2022 and is continuing to evaluate the new guidance to determine the impact it will have on its condensed consolidated financial statements.  

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 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.  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.  Rental revenue is recognized as earned over the rental period if collectability of the rent is reasonably assured.  Rentals of the Company’s equipment generally range from daily rentals to minimum rental periods of up to six months or longer.  The Company has determined that ASC 606 does not apply to rental contracts, which are within the scope of ASC Topic 842, Leases.  

As permissible under the new standard, 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.

During the third quarter of fiscal year 2020, the Company was awarded a $10.5 million contract (inclusive of a subsequent contract amendment of $0.3 million) with the U.S. Customs and Border Protection (“CBP”) to provide a technology solution to the Department of Homeland Security.  Revenue recognized under the contract for fiscal year 2020 and for the six months ended March 31, 2021 was $0.3 million and $8.9 million, respectively.  The Company had unbilled receivables of $2.7 million at March 31, 2021 under this contract.  Unrecognized revenue for unsatisfied performance obligations on this contract at March 31, 2021 was approximately $1.3 million.  The Company anticipates the revenue on the remaining performance obligation on this contract will be recognized in fiscal year 2021.  Unsatisfied performance obligations on all other contracts held by the Company at March 31, 2021 had an original duration of one year or less.

At March 31, 2021, the Company had no deferred contract costs or deferred contract liabilities.  At September 30, 2020, the Company had no deferred contract costs and $0.2 million  deferred contract liabilities, which are included in current liabilities on the Company’s consolidated balance sheet as a component of deferred revenue and other liabilities.  During the three and six months ended March 31, 2021, no revenue and $0.2 million, respectively, was recognized from deferred contract liabilities.  During the three and six months ended March 31, 2020, no revenue was recognized from deferred contract liabilities.  No cost of revenue was recognized from deferred contract costs for the three and six months end March 31, 2021 and 2020.                                   

9

During the second quarter of fiscal year 2020, the Company partially financed a $12.5 million product sale by entering into a $10.0 million promissory note with the customer.  The note is for a three-year term with monthly principal and interest payments of $0.3 million.  Due to the financial condition of the customer, the Company had concerns over the probable collectability of the promissory note.  As a result, the Company did not recognize any revenue or cost of revenue on the product sale through its first quarter of fiscal year 2021. During the second quarter of fiscal year 2021, as a result of new information received from the customer, management determined that it is probable that the customer will satisfy its remaining payment obligations on the promissory note with the Company and recognized revenue of $12.5 million on the product sale.  The customer is current on its payment obligations and has made payments totaling $6.1 million (exclusive of interest) as of March 31, 2021 related to the product sale.           

For each of the Company’s operating segments, the following table presents revenue only from the sale of products and the performance of services under contracts with customers (in thousands).  Therefore, the table excludes all revenue earned from rental contracts.

3.   Investments

Short-term Investments

The Company classifies its short-term investments as available-for-sale securities.  Available-for-sale 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.  No realized gains or losses were recognized during the three and six months ended March 31, 2021 and 2020.  

The Company’s short-term investments were composed of the following (in thousands):

	As of March 31, 2021 (in thousands)
	Amortized Cost		Unrealized Gains			Unrealized Losses		Estimated Fair Value
Short-term investments:
Corporate bonds	$	3,868	$	(3	)	$	—	$	3,865

The Company had no short-term investments at September 30, 2020.

The Company’s short-term investments had contractual maturities ranging from September 2021 to May 2022.

Investment in Debt Security

On July 13, 2020, the Company received an interest in a senior secured bond issued from an international seismic marine customer.  The Company’s interest in the bond, which has a face value of $13.0 million, was received in exchange for $13.0 million of unpaid invoices and late fees owed by the customer.  The bond is secured by a third in line lien on the assets owned by the customer and has an 8% interest rate with bi-annual interest and possible principal payments based on available excess cash flows.  Interest payments can be made either in cash or in-kind payments in the form of additional debt security.  In-kind interest payments require an 8.8% interest rate.  The bond matures on July 13, 2022. The bond is listed on the Oslo Alternative Bond Market; however, the actual marketability of the bond is unknown at this time.

Upon receipt of the senior secured bond, the Company performed a fair value assessment of the investment to determine the bond’s initial carrying amount.  In accordance with ASC 825, “Fair Value Instruments”, the Company has determined that the investment is a Level 3 financial instrument primarily due to its current unknown marketability.  Because of the distressed financial condition of the customer, the Company believes the fair value of the bond is nominal.

  In January 2021, the Company transferred the security pursuant to a purchase agreement (the “Agreement”) entered with a third party (the “Buyer”).   Pursuant to the Agreement, the Company received non-refundable consideration of $0.3 million and will receive additional cash compensation of $2.4 million from the Buyer if certain terms and conditions between the Buyer and the Company’s customer are met by December 31, 2021.  In the event these terms and conditions are not met, the Company has the option to reacquire the bond from the Buyer for one dollar US ($1.00).  The Company recognized a gain on investment of $0.3 million during the three months ended March 31, 2021 in connection with the transfer of the bond.

4.   Fair Value of Financial Instruments

The Company’s financial instruments generally include cash and cash equivalents, short-term investments, trade accounts, notes receivable and accounts payable.  Due to the short-term maturities of cash and cash equivalents, trade accounts, notes receivable and accounts payable, the carrying amounts of these financial instruments are deemed to approximate their fair value on the respective balance sheet dates.  The valuation technique used to measure the fair value of the contingent consideration was derived from models utilizing market observable inputs.  

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

The following tables present the fair value of the Company’s short-term investments and contingent consideration by valuation hierarchy and input (in thousands):

11

Non-current contingent consideration	$	—	$	—	$	(10,962	)	$	(10,962	)

The following table summarizes changes in the fair value of the Company’s Level 3 financial instruments for the six months ended March 31, 2021:

Balance at October 1, 2020	$	10,962
Fair value adjustments		(697	)
Balance at December 31, 2020		10,265
Fair value adjustments		(221	)
Balance at March 31, 2021	$	10,044

Adjustments to the fair value of the contingent consideration are based on Monte Carlo simulations or the probability-weighted expected return method utilizing inputs which include market comparable information and management assessments regarding potential future scenarios.  The Company believes its estimates and assumptions are reasonable, however, there is significant judgment involved.

5.   Trade Accounts and Notes Receivable

Trade accounts receivable, net (excluding notes receivable) are reflected in the following table (in thousands):

	March 31, 2021			September 30, 2020
Trade accounts receivable	$	7,606		$	14,090
Allowance for doubtful accounts		(523	)		(496	)
Total	$	7,083		$	13,594

The allowance for doubtful accounts represents the Company’s best estimate of probable credit losses.  The Company determines the allowance based upon historical experience and a current review of its trade accounts receivable balances.  Trade accounts receivable balances are charged off against the allowance whenever it is probable that the receivable balance will not be recoverable.              

Notes receivable are reflected in the following table (in thousands):

	March 31, 2021			September 30, 2020
Notes receivable	$	6,525		$	184
Less current portion		(3,448	)		(184	)
Non-current notes receivable	$	3,077		$	—

12

Promissory notes receivable are generally collateralized by the products sold, and bear interest at rates ranging up to 8% per year.  The promissory notes receivable mature at various times through January 2023.  The Company has, on occasion, extended or renewed notes receivable as they mature, but there is no obligation to do so.

During the second quarter of fiscal year 2020, the Company partially financed a $12.5 million product sale by entering into a $10.0 million promissory note with the customer.  The note is for a three-year term with monthly principal and interest payments of $0.3 million.  Due to the financial condition of the customer, the Company had concerns over the probable collectability of the promissory note.  As a result, the note receivable was not reflected on the Company’s consolidated balance sheet through its first quarter of fiscal year 2021. During the second quarter of fiscal year 2021, as a result of a new information received from the customer, management determined that it is probable that the customer will satisfy its remaining payment obligations to the Company and has recognized the promissory note on its consolidated balance sheet as of March 31, 2021.  See Note 2 for more information on this matter.

During the first quarter of fiscal year 2021, the Company entered into a $13.2 million short-term promissory note with a customer related to the sale of rental equipment and an outstanding receivable balance.   The note, which bore interest at 8% per annum, was paid during the three months ended March 31, 2021.

Weighted average remaining lease term	6.0 years			1.0 year
Weighted average discount rate		3.25	%		5.00	%

The discount rate used on the operating right-of-use assets represented the Company’s incremental borrowing rate at lease inception.

As Lessor

The Company leases equipment to customers primarily for terms of six months or less.  All of the Company’s leasing arrangements as lessor are classified as operating leases.  The majority of the Company’s rental revenue is generated from its marine-based wireless seismic data acquisition system.

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.  The Company suspends revenue recognition when the collectability of amounts due are no longer probable and concurrently records a direct write-off of the lease receivable to rental revenue and limits future rental revenue recognition to cash received.  As of March 31, 2021, the Company had lease receivables from customers, net of reserves, of approximately $1.8 million.

Rental revenue for the three and six months ended March 31, 2021 was $2.3 million and $4.0 million, respectively.   Rental revenue for the three and six months ended March 31, 2020 was $16.4 million and $25.0 million, respectively.  

At March 31, 2021, future minimum lease obligations due from the Company’s leasing customers (all in fiscal year 2021) were $7.1 million.  

Rental equipment consisted of the following (in thousands):

	March 31, 2021			September 30, 2020
Rental equipment, primarily wireless recording equipment	$	90,399		$	114,783
Accumulated depreciation and impairment		(52,017	)		(60,466	)
	$	38,382		$	54,317

During the second quarter of fiscal year 2021, the Company entered into a memorandum of understanding with a customer to lease land-based wireless seismic rental equipment from its rental fleet.  The transaction is expected to be in the form of a sales-type lease with ownership of the equipment transferring to the customer upon completion of the lease, which has a term of six months.  The carrying amount of the equipment to be leased is $1.3 million and has been reclassified from rental equipment to assets held for sale on its consolidated balance sheet as of March 31, 2021.  Total lease payments due from the customer under the lease exceed the equipment’s carrying value.  The Company anticipates the transaction will be consummated during the third quarter of fiscal year 2021.

8.   Assets Held for Sale

Property, Plant & Equipment

The Company owns a property located in Bogotá, Colombia that it is marketing for sale.  The property was used for warehousing its rental equipment operations, product sales and service support to its customers in South America.  The property’s carrying value at March 31, 2021 and September 30, 2020 of $0.5 million and $0.6 million, respectively, is classified as an asset held for sale in the accompanying consolidated balance sheets as of December 31, 2020 and September 30, 2020.  The Company has been marketing the property since the second quarter of fiscal year 2020.  The Company believes the fair market value of the property exceeds its carrying value and that the property will be sold within the next 12-months.

Rental Equipment

The Company classified rental equipment with a carrying value of $1.3 million as assets held for sale on its consolidated balance sheet as of March 31, 2021.  See Note 7 for more information.

10.   Stock-Based Compensation

During the six months ended March 31, 2021, the Company issued 189,950 restricted stock units (“RSUs”) under its 2014 Long Term Incentive Plan, as amended (the “Plan”).  The RSUs issued include both time-based and performance-based vesting provisions.  The weighted average grant date fair value of each RSU was $6.96 per unit.  The grant date fair value of the RSUs was $1.3 million, which will be charged to expense over the next four years as the restrictions lapse.  Compensation expense for RSUs was

15

determined based on the closing market price of the Company’s stock on the date of grant applied to the total number of units that are anticipated to fully vest. Each RSU represents a contingent right to receive one share of the Company’s common stock upon vesting.  As of March 31, 2021, the Company had unrecognized compensation expense of $3.1 million relating to RSUs that is expected to be recognized over a weighted average period of 2.8 years.

As of March 31, 2021, the Company had $0.5 million of unrecognized compensation expense related to restricted stock awards (“RSAs”) that is expected to be recognized over a weighted average period of 0.9 years.

11.   Loss Per Common Share

           The following table summarizes the calculation of net loss and weighted average common shares and common equivalent shares outstanding for purposes of the computation of loss per share (in thousands, except share and per share data):

	Three Months Ended						Six Months Ended
	March 31, 2021			March 31, 2020			March 31, 2021			March 31, 2020
Net loss	$	(7,184	)	$	(3,811	)	$	(8,234	)	$	(13,093	)
Less: Loss allocable to unvested restricted stock		—			—			—			—
Loss attributable to common shareholders for    diluted earnings per share	$	(7,184	)	$	(3,811	)	$	(8,234	)	$	(13,093	)
Weighted average number of common share equivalents:
Common shares used in basic loss per share		13,466,614			13,541,404			13,519,638			13,503,486
Common share equivalents outstanding related to    stock options and RSUs		—			—			—			—
Total weighted average common shares and common    share equivalents used in diluted loss per share		13,466,614			13,541,404			13,519,638			13,503,486
Loss per share:
Basic	$	(0.53	)	$	(0.28	)	$	(0.61	)	$	(0.97	)
Diluted	$	(0.53	)	$	(0.28	)	$	(0.61	)	$	(0.97	)

For the calculation of diluted loss per share for the three and six months ended March 31, 2021, 38,800 stock options and 334,687 non-vested RSUs were excluded in the calculation of weighted average shares outstanding since their impact on diluted loss per share was antidilutive.  For the calculation of diluted loss per share for the three and six months ended March 31, 2020, 103,100 stock options and 265,220 non-vested RSUs, respectively, were excluded in the calculation of weighted average shares outstanding since their impact on diluted loss per share was antidilutive.

12.   Commitments and Contingencies

Contingent Consideration

In connection with its acquisitions of Quantum Technology Sciences, Inc. (“Quantum”) and the OptoSeis^® fiber optic sensing technology business, the Company recorded contingent purchase price payments, or contingent consideration, that may be owed in the future.  For both acquisitions, the contingent payments are based on future receipt of contract awards and the resulting revenue derived from such contracts.  The Company utilizes the services of independent valuation consultants to assist with the estimation of the fair value of this contingent consideration.  The determination of fair value is inherently unpredictable since it requires estimates and projections of future revenue, including the size, length, timing and, in the case of Quantum, the extent of gross profits earned under its future contracts.  As a result, the Company anticipates fair value adjustments to these liabilities over the respective earn-out periods, and these adjustments will result in either charges or credits to the Company’s operating expenses when the fair value of the contingent consideration increases or decreases, respectively.  

The Company recorded an initial contingent earn-out liability of $7.7 million in connection with its July 2018 acquisition of Quantum.   Contingent payments, if any, may be paid in the form of cash or Company stock and will be derived from eligible revenue generated during a four-year earn-out period ending July 2022.  The maximum amount of contingent payments is $23.5 million over the four-year earn-out period.  At September 30, 2020, the contingent earn-out liability was valued at $5.8 million.  During the six months ended March 31, 2021, the Company recorded an adjustment of $0.8 million to decrease the liability to an estimated fair value of $5.0 million.  The decrease in the earn-out liability for the six months ended March 31, 2021 was due to a decrease in projected eligible revenue.  The Company made a cash earn-out payment of $0.1 million in fiscal year 2020 to the former shareholders of Quantum.  The Company plans to make an additional earn-out payment of approximately $2.3 million in the fourth quarter of fiscal year 2021.       

16

The Company recorded an initial contingent earn-out liability of $4.3 million in connection with its November 2018 acquisition of all the intellectual property and related assets of the OptoSeis^® fiber optic sensing technology.  Contingent cash payments, if any, will be derived from eligible revenue generated during a five-and-a-half year earn-out period ending in May 2024.  The maximum amount of contingent payments is $23.2 million over the five-and-a-half year earn-out period.  At September 30, 2020, the contingent earn-out liability was valued at $5.2 million.  During the six months ended March 31, 2021, the Company recorded an adjustment of $0.1 million to decrease the liability to an estimated value of $5.1 million.      

 The Company reviews and assesses the fair value of its contingent earn-out liabilities on a quarterly basis.    

Operating Leases

The Company leases office space and certain equipment for terms of seven years or less.  As of March 31, 2021, future minimum lease payment obligations were $1.5 million.    

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 these pending matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

13.   Segment Information

The Company reports and evaluates financial information for three operating segments:  Oil and Gas Markets, Adjacent Markets and Emerging Markets.  The Oil and Gas Markets segment 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, marine streamer retrieval and steering devices and various other seismic products.  The Adjacent Markets segment products include imaging equipment, water meter products, offshore cables, and seismic sensors used for vibration monitoring and geotechnical applications such as mine safety applications and earthquake detection.  The Emerging Markets segment provides seismic products targeted at the border and perimeter security markets.

The following table summarizes the Company’s segment information (in thousands):

	Three Months Ended						Six Months Ended
	March 31, 2021			March 31, 2020			March 31, 2021			March 31, 2020
Revenue:
Oil and Gas Markets	$	16,132		$	18,434		$	28,895		$	29,943
Adjacent Markets		7,595			7,101			14,495			13,200
Emerging Markets		165			372			8,962			469

Total	$	(8,176	)	$	(3,489	)	$	(9,635	)	$	(11,312	)

14.   Income Taxes

Consolidated income tax expense for the three and six months ended March 31, 2021 was $0.1 million and $0.1 million, respectively.  Consolidated income tax expense for the three and six months ended March 31, 2020 was $0.6 million and $2.0 million, respectively.  This decrease in fiscal year 2021 income tax expense was primarily the result of a decrease in rental revenue earned in foreign jurisdictions requiring tax withholding. The Company is currently unable to record any tax benefits from the tax losses it incurs in the U.S., Canada and Russian Federation due to the uncertainty surrounding its ability to utilize such losses in the future to offset taxable income.

15.  Risks and Uncertainties   

Concentration of Credit Risk

As of March 31, 2021, the Company had combined trade accounts and notes receivable and unbilled receivables from three customers of $6.9 million, $4.2 million and $1.0 million.  During the six months ended March 31, 2021, revenue recognized from these three customers was $13.2 million, $12.7 million and $8.9 million, respectively.   

COVID-19 Pandemic

The ongoing COVID-19 pandemic has spread across the globe and has negatively impacted worldwide economic activity, including the global demand for oil and natural gas, and continues to create challenges in the Company’s markets.  In addition to measures the Company has taken voluntarily, the government authorities in the Company’s markets have taken actions to mitigate the spread of COVID-19, including travel restrictions, border closings, restrictions on public gatherings, stay-at-home orders and other quarantine and isolation measures. Following the initial outbreak of the virus, the Company experienced disruptions in its supply chain, a reduction in demand for certain products, cancellation of rental contracts and difficulty with field employees and salespeople traveling domestically and abroad to conduct the Company’s business. COVID-19 continues to pose the risk that the Company or its employees, contractors, suppliers and customers may be prevented from conducting business activities for an indefinite period of time, including potential spread of the disease within these groups or restrictions that may be requested or mandated by governmental authorities, including quarantines of certain geographic areas, restrictions on travel and other restrictions that prohibit employees from going to work, both around the world as well as in certain jurisdictions in the United States.  The continued spread of COVID–19 and the related mitigation measures have disrupted the Company’s supply chain, resulting in longer lead times in materials shipped from suppliers and extended the shipping time for these materials to reach the Company’s facilities.  If COVID–19 continues to spread or the response to contain the COVID–19 pandemic is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and liquidity.

Decrease in Oil Commodity Price Levels

Demand for many of the Company’s products and the profitability of its 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 the Company’s products.  Conversely, in periods when these energy commodity prices deteriorate, capital spending budgets of oil and natural gas operators tend to contract and the demand for the Company’s products generally weakens.  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 its 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, 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 OPEC to set and maintain production levels and prices of foreign imports.

Sustained low oil prices or the failure of oil prices to rise in the future and the resulting downturns or lack of growth in the energy industry and energy‑related business, could have a negative impact on the Company’s results of operations and financial condition. In light of the decline in oil prices caused by the COVID-19 pandemic in 2020, oil and gas exploration and production companies experienced a significant reduction in cash flows, which resulted in reductions in their capital spending budgets for oil and gas exploration-focused activities, including seismic data acquisition activities.  Demand for the sale of the Company’s seismic products targeted at customers in its Oil and Gas Markets segment, which has historically accounted for the majority of its revenue, significantly declined during fiscal year 2020, and both product sales and rental revenue could significantly diminish during the remainder of fiscal year 2021 or beyond as a result of significant uncertainty in the outlook for oil and gas exploration.  Specifically, the Company expects these challenging industry conditions to result in decreased demand for its marine wireless nodal products and its land-based seismic products, as the demand for such products has been, and will likely continue to be, vulnerable to downturns in the economy and the oil and gas industry in general.  In addition to the negative effects of slowdowns in the United States economy, slowing economic growth in growing economies like those in China and India could lead to a decline in demand for crude oil and natural gas.  Slowdowns in economic activity would likely reduce worldwide demand for energy and result in an extended period of lower crude oil and natural gas prices.  Any material changes in oil and gas prices or other market trends that adversely impact seismic exploration activity 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 the Company’s oil and gas products may be adversely affected when world supplies exceed demand.

Products and Product Development

Oil and Gas Markets

Our Oil and Gas Markets 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, marine streamer retrieval and steering devices and various other seismic products.  We believe that our Oil and Gas Markets products are among the most technologically advanced instruments and equipment available for seismic data acquisition.

Traditional Products

An energy source and a data recording system are combined to acquire seismic data.  We provide many of the components of seismic data recording systems, including geophones, hydrophones, multi-component sensors, leader wire, geophone strings, connectors, seismic telemetry cables and other seismic related products.  On land, our customers use geophones, leader wire, cables and connectors to receive and measure seismic reflections resulting from an energy source into data recording units, which store the seismic information for subsequent processing and analysis.  In the marine environment, large ocean-going vessels tow long seismic cables known as “streamers” containing hydrophones that are used to detect pressure changes.  Hydrophones transmit electrical impulses back to the vessel’s data recording unit where the seismic data is stored for subsequent processing and analysis.  Our marine seismic products also help steer streamers while being towed and help recover streamers if they become disconnected from the vessel.

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.

Wireless Products

We have developed multiple versions of a land-based wireless (or nodal) seismic data acquisition system.  Rather than utilizing interconnecting cables as required by most traditional land data acquisition systems, each of our wireless stations operate as an independent data collection system, allowing for virtually unlimited channel configurations.  As a result, our wireless systems require less maintenance, which we believe allows our customers to operate more effectively and efficiently because of its reduced environmental impact, lower weight and ease of operation.  Each wireless station is available in a single-channel or three-channel configuration.  Since its introduction in 2008 and through March 31, 2021, we have sold 473,000 wireless channels and we currently have 84,000 wireless channels in our rental fleet.  

We have also developed a marine-based wireless seismic data acquisition system called the OBX.  Similar to our land-based wireless systems, the marine OBX system may be deployed in virtually unlimited channel configurations and does not require interconnecting cables between each station.  Our deepwater versions of the OBX system can be deployed in depths of up to 3,450 meters.  Through March 31, 2021, we have sold 8,400 OBX stations and we currently have 25,000 OBX stations in our rental fleet.  

Reservoir Products

Seismic surveys repeated over selected time intervals show dynamic changes within a producing oil and gas reservoir, and operators can use these surveys to monitor the effects of oil and gas development and production.  This type of reservoir monitoring requires special purpose or custom designed systems in which portability becomes less critical and functional reliability assumes greater importance.  This reliability factor helps assure successful operations in inaccessible locations over a considerable period of time.  Additionally, reservoirs located in deep water or harsh environments require special instrumentation and new techniques to maximize recovery.  Reservoir monitoring also requires high-bandwidth, high-resolution seismic data for engineering project planning and reservoir management.  Utilizing these reservoir monitoring tools, producers can enhance the recovery of oil and gas deposits over the life of a reservoir.

We have developed permanently installed high-definition reservoir monitoring systems for land and ocean-bottom applications in producing oil and gas fields.  Our electrical reservoir monitoring systems are currently installed on numerous offshore

20

reservoirs in the North Sea and elsewhere.  Through our acquisition of the OptoSeis^® fiber optic sensing technology, we now offer both electrical and fiber optic reservoir monitoring systems.  These high-definition seismic data acquisition systems have a flexible architecture allowing them to be configured as a subsurface system for both land and marine reservoir-monitoring projects.  The scalable architecture of these systems enables custom designed configuration for applications ranging from low-channel engineering and environmental-scale surveys requiring a minimum number of recording channels to high-channel surveys required to efficiently conduct permanent reservoir monitoring (“PRM”).  The modular architecture of these products allows virtually unlimited channel expansion for these systems.  

In addition, we 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.

We believe our reservoir characterization products make seismic acquisition a cost-effective and reliable process for reservoir monitoring.  Our multi-component seismic product developments also include an omni-directional geophone for use in reservoir monitoring, a compact marine three-component or four-component gimbaled sensor and special-purpose connectors, connector arrays and cases.

In September 2020, we received a request from a major oil and gas producer for a proposal to manufacture a large-scale seabed PRM system.  Under the offered terms and conditions as initially presented, we decided not to provide a bid to the customer.  However, we are in further discussions with this customer to try and resolve the issues necessary to provide a PRM system. We do not know exactly when or if these discussions will lead to a resolution or the award of a proposal. We have also held discussions and received requests for information from other major oil and gas producers regarding PRM systems. We have not received any orders for a large-scale seabed PRM system since November 2012. 

Adjacent Markets

Our Adjacent Markets businesses leverage upon existing manufacturing facilities and engineering capabilities utilized by our Oil and Gas Markets businesses.  Many of the seismic products in our Oil and Gas Markets segment, with little or no modification, have direct application to other industries.  

Industrial Products

Our industrial products include water meter products, contract manufacturing products, offshore cables, and seismic sensors used for vibration monitoring and geotechnical applications such as mine safety applications and earthquake detection.

Imaging Products

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

Emerging Markets

Our Emerging Markets business segment consists entirely of our Quantum business.  Quantum’s product line includes a proprietary detection system called SADAR^®, 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.  In addition to its commercial base of customers, Quantum’s customers primarily include various agencies of the U.S. government including the Department of Defense, Department of Energy, Department of Homeland Security and other agencies.

Overview

     In 2014, our Oil and Gas Markets segment experienced a softening in the demand for its traditional exploration products, particularly in North America, as capital budgets for oil and gas producers were trending away from exploration-focused activities toward production and exploitation activities.  During this period oil production in North America’s unconventional shale reservoirs increased, as did oil production from other non-OPEC countries, resulting in an oversupply of crude oil in the world market and a resulting drop in energy prices.  In February 2020, decreased demand again caused by the oversupply of crude oil due to failed OPEC negotiations and, when combined with the impact of the COVID–19 pandemic, led to a dramatic drop in crude oil prices.  These declines in the demand for oil and gas have caused oil and gas exploration and production companies to experience a significant reduction in cash flows, which have resulted in and will likely continue to result in reductions in their capital spending budgets for oil and gas exploration-focused activities, including seismic data acquisition activities.  Our Oil and Gas Markets segment has in recent years experienced strong demand for the rental of our marine wireless nodal products; however, this demand has significantly declined during fiscal year 2021 and could continue to decline in future years as a result of the significant uncertainty in the outlook for oil and gas exploration.  Demand for new land-based seismic equipment in recent fiscal years has remained restrained due to capital limitations affecting many of our customers, along with their excess levels of underutilized equipment. As a result, revenue from the sale and rental of our land-based traditional and wireless products has remained low due to the reduced investment in exploration-focused seismic activities.  Policies implemented by the Biden administration in the United States could also result in decreased demand for our products.  President Biden has announced climate change as a core focus of his administration and that he intends to set the United States on a path to net-zero carbon emissions by 2050. In January of 2021, President Biden implemented a hold on issuing new drilling permits and new oil and gas leasing for federal lands and waters.  The administration may also implement new or amended rules and regulations concerning hydraulic fracturing and emissions from oil and gas sector operations. Crude oil prices have recently rebounded above February 2020 levels; however, oil and gas pricing and the resultant economic conditions may not recover meaningfully in the long term, and we expect these challenging industry conditions will result in decreased revenue from our Oil and Gas Markets segment products in fiscal year 2021.  

22

In light of current market conditions, the inventory balances in our Oil and Gas Markets business segment at March 31, 2021 continued to exceed levels we consider appropriate for the current level of product demand.  While we are aggressively working to reduce these legacy inventory balances, we are also adding new inventories for new wireless product developments and for other product demand in our Adjacent Markets segment.  During periods of excessive inventory levels, our policy has been, and will continue to be, to record obsolescence expense as we experience reduced product demand and as our inventories continue to age.  If difficult market conditions continue for the products in our Oil and Gas Markets segment, we expect to record additional inventory obsolescence expense in fiscal year 2021 and beyond until product demand and/or resulting inventory turnover return to acceptable levels.

23

Coronavirus (COVID-19)

The ongoing COVID-19 pandemic has spread across the globe and has negatively impacted worldwide economic activity, including the global demand for oil and natural gas, and continues to create challenges in our markets. While we continue to support our customers, there remain uncertainties regarding the duration and the extent to which the COVID-19 pandemic will ultimately have a negative impact on the demand for our products and services or on our supply chain.  We continue to closely monitor the situation as information becomes readily available.

As of the date of this filing, our operations have, for the most part, remained open globally and the impact of the effects of COVID-19 to our personnel and operations has been limited.  We have experienced lower than expected sales in our Oil and Gas Markets and Adjacent Markets segments and a reduction in demand for the rental of our OBX marine nodal products, which we believe is primarily the result of the pandemic.  Our supply chain has become increasingly strained due to increased pricing for raw material and supplies coupled with longer than expected lead times. We continually communicate with our suppliers and customers as information is available to best manage this difficult situation.  We have also experienced difficulties with field employees and salespeople traveling domestically and abroad to conduct our business.

Cost Reduction Initiative

In July 2020, we initiated a program to reduce operating and manufacturing expenses in light of decreased demand for products in our Oil and Gas Markets and Adjacent Markets segments.  The program is expected to produce approximately $2.0 million of annualized cash savings.  The cost reductions were primarily realized through a reduction of employees from our workforce.  In connection with the workforce reductions, we incurred $0.9 million of termination costs in our fourth quarter of fiscal year 2020.  The termination costs were recorded to both cost of revenue and operating expenses in the consolidated statement of operations.  There are no outstanding liabilities related to this program as of March 31, 2021.    

Three and six months ended March 31, 2021 compared to the three and six months ended March 31, 2020

Consolidated revenue for the three months ended March 31, 2021 was $23.9 million, a decrease of $2.0 million, or 7.8%, from the corresponding period of the prior fiscal year.  The decrease in revenue for the three months ended March 31, 2021 was primarily due to a decrease in rental revenue from our OBX marine nodal products primarily due to the sale of rental equipment in our first quarter and lower utilization of our OBX rental fleet caused by the COVID-19 pandemic.  The decrease was largely offset by an increase in land-based wireless seismic product revenue attributable to the recognition of revenue on a large product delivery which occurred in the prior fiscal year.  Consolidated revenue for the six months ended March 31, 2021 was $52.4 million, an increase of $8.7 million, or 20.0%, from the corresponding period of the prior fiscal year.  The increase in revenue for the six months ended March 31, 2021 was primarily due to (i) a $12.5 million of wireless product revenue attributable to the recognition of revenue on the large land-based wireless seismic product delivered in fiscal year 2020, (ii) a $9.9 million sale of used OBX rental equipment to the former lessee of the equipment and (iii) revenue of $9.0 million recognized from our Emerging Markets segment related to our contract with the CBP, which was awarded to us in fiscal year 2020.  The increase in revenue for the six months ended March 31, 2021 was partially offset by a decrease in rental revenue from our OBX marine nodal products primarily due to the sale of rental equipment in our first quarter and lower utilization of our OBX rental fleet caused by the COVID-19 pandemic.  

Consolidated gross profit for the three months ended March 31, 2021 was $0.8 million, compared to $7.9 million for the corresponding period of the prior fiscal year.  The decrease in gross profit for the three months ended March 31, 2021 was caused by the by the reduction of rental revenue discussed above, and was partially offset by an increase in gross profits from our land-based wireless seismic products attributed to the recognition of revenue from a product delivery in the prior fiscal year.  Consolidated gross profit for the six months ended March 31, 2021 was $7.6 million, compared to $10.4 million for the corresponding period of the prior fiscal year.  The decrease in gross profit for the six months ended March 31, 2021 was primarily due to a decrease in wireless product rental revenue, and was partially offset by (i) an increase wireless product gross profit attributable to the revenue recognized on the large land-based wireless seismic product delivery in the prior year, (ii) gross profit from the sale of OBX rental equipment to the former lessee of the equipment and (iii) gross profit realized on our contract with the CBP.

Consolidated operating expenses for the three months ended March 31, 2021 were $9.0 million, a decrease of $2.4 million, or 20.9%, from the corresponding period of the prior fiscal year.    The decrease was due to (i) a $0.6 million decrease in personnel costs primarily related to our cost reduction program initiated in the third quarter of fiscal year 2020, (ii) a $1.2 million net non-cash decrease in the estimated fair value of contingent earn-out consideration related to our Quantum and OptoSeis^® acquisitions and (iii) a $0.6 million reduction in other general business expenses related to our business operations.   Consolidated operating expenses for the six months ended March 31, 2021 were $17.2 million, a decrease of $4.5 million, or 20.8%, from the corresponding period of the prior fiscal year.  The decrease was due to (i) a $1.9 million net non-cash decrease in the estimated fair value of contingent earn-out consideration related to our Quantum and OptoSeis^® acquisitions, (ii) $1.2 million decrease in personnel costs primarily related to our cost reduction program initiated in the third quarter of fiscal year 2020, (iii) a $0.4 million reduction in research and development project costs and (iv) a $1.0 million reduction in other general business expenses related to our business operations.

24

Consolidated other income for the three months ended March 31, 2021 was $1.1 million compared to $0.3 million from the corresponding period of the prior fiscal year.  Consolidated other income (loss) for the six months ended March 31, 2021 was $1.5 million compared to $0.2 million from the corresponding period of the prior fiscal year.  The increase in other income for both periods was primarily caused by an increase in interest and investment income.  

Consolidated income tax expense for the three months ended March 31, 2021 was $0.1 million compared to $0.6 million from the corresponding period of the prior fiscal year.  Consolidated income tax expense for the six months ended March 31, 2021 was $0.1 million compared to $2.0 million from the corresponding period of the prior fiscal year.  This decrease in income tax expense for both periods was primarily the result of a decrease in rental revenue earned in foreign jurisdictions requiring tax withholding.  We are currently unable to record any tax benefits from the tax losses we incur in the U.S., Canada and Russian Federation due to the uncertainty surrounding our ability to utilize such losses in the future to offset taxable income.

Segment Results of Operations

Oil and Gas Markets

Revenue

Revenue from our Oil and Gas Markets products for the three months ended March 31, 2021 decreased $2.3 million, or 12.5%, from the corresponding period of the prior fiscal year.  Revenue from our Oil and Gas Markets products for the six months ended March 31, 2021 decreased $1.0 million, or 3.5%, from the corresponding period of the prior fiscal year.   Our product and rental revenue in this segment was negatively impacted by the COVID-19 pandemic and its impact on worldwide demand for crude oil, and positively impacted by the sale of used OBX rental equipment to the former lessee of the equipment in the first quarter of fiscal year 2021. The components of these decreases included the following:

• Traditional Exploration Product Revenue – For the three months ended March 31, 2021, revenue from our traditional products decreased $1.2 million, or 61.1% from the corresponding period of the prior fiscal year.  For the six months ended March 31, 2021, revenue from our traditional products decreased $2.6 million, or 59.3% from the corresponding period of the prior fiscal year.  The decrease for both periods reflects lower demand for our marine products and a decrease in customer product repair and support service revenue.  

• Wireless Exploration Product Revenue – For the three months ended March 31, 2021, revenue from our wireless exploration products decreased $1.3 million, or 8.1%, from the corresponding period of the prior fiscal year.  The decrease for the three months ended March 31, 2021 was primarily due to a decrease in rental revenue from our OBX marine nodal products caused by a large sale of OBX rental equipment to the former lessee of the equipment in the first quarter of fiscal year 2021 and due to lower utilization of our OBX rental fleet caused by the COVID-19 pandemic.  The decrease was largely offset by the recognition of $12.5 million of revenue related to land-based wireless seismic products delivered to a customer in the prior fiscal year. For the six months ended March 31, 2021, revenue from our wireless exploration products increased $1.5 million, or 6.0%, from the corresponding period of the prior fiscal year.  The increase for the six months ended March 31, 2021 was primarily due to the recognition of $12.5 million of revenue on the land-based wireless system and from the $9.9 million sale of used OBX rental equipment to the former lessee of the equipment. These increases were largely offset by the significant decrease in OBX rental revenue.

25

• Reservoir Product Revenue – For the three months ended March 31, 2021, revenue from our reservoir products increased $0.2 million, or 69.4%, from the corresponding period of the prior fiscal year.  For the six months ended March 31, 2021, revenue from our reservoir products increased $45,000, or 8.1%, from the corresponding period of the prior fiscal year.  The increase for both periods was primarily due to higher reservoir-related service revenue.

Operating Income (Loss)

Operating income (loss) associated with our Oil and Gas Markets products for the three months ended March 31, 2021 was $(5.5) million, compared to operating income of $1.3 million from the corresponding period of the prior fiscal year.  Operating loss associated with our Oil and Gas Markets products for the six months ended March 31, 2021 was $(11.5) million, compared to $(2.6) million from the corresponding period of the prior fiscal year.  The decrease in operating income for both periods was primarily due to (i) lower wireless rental revenue and related gross profits from the rental of our OBX systems and (ii) an increase in unutilized factory costs resulting from lower productivity.  The decrease in operating income for both periods was partially offset by (i) the sale of the OBX rental equipment to the former lessee of the equipment, (ii) the recognition of revenue on the land-based wireless system delivered in the prior year, and (iii) lower operating expenses resulting from our fiscal year 2020 cost reduction program and other related cost reductions.  

Adjacent Markets

Revenue

Revenue from our Adjacent Markets products for the three months ended March 31, 2021 increased $0.5 million, or 7.0%, from the corresponding period of the prior fiscal year.  Revenue from our Adjacent Markets products for the six months ended March 31, 2021 increased $1.3 million, or 9.8%, from the corresponding period of the prior fiscal year.  The components of these increases included the following:

• Industrial Product Revenue and Services – For the three months ended March 31, 2021 revenue from our industrial products increased $0.8 million, or 18.9% from the corresponding period of the prior fiscal year.  For the six months ended March 31, 2021 revenue from our industrial products increased $1.6 million, or 20.6% from the corresponding period of the prior fiscal year.  The increase in revenue for both periods was primarily due to higher demand for water meter products and contract manufacturing services.  While we experienced an increase in the demand for products during the three and six months ended March 31, 2021 despite the current COVID-19 pandemic, we cannot reasonably determine if this marks the beginning of a recovery from the impact of the COVID-19 pandemic for this operating segment.  As a result, we are unable to determine the lasting effect the COVID-19 pandemic will have on the future demand for our industrial products and services.

• Imaging Product Revenue – For the three months ended March 31, 2021, revenue from our imaging products decreased $0.3 million, or 10.2%, from the corresponding period of the fiscal year.  For the six months ended March 31, 2021 revenue from our imaging products decreased $0.3 million, or 5.7%, from the corresponding period of the prior fiscal year. The decrease for both periods was primarily due to lower demand for our consumable film products partially offset by increased demand for our equipment products.  Demand for our consumable film products continues to be impacted by the current COVID-19 pandemic.  We expect this lower demand for our film products to continue until large scale social gatherings resume where our customers use these products.

The operating income from our Adjacent Markets products for the three months ended March 31, 2021 was $1.6 million, an increase of $0.3 million, or 28.7%, from the corresponding period of the prior fiscal year.   The operating income from our Adjacent Markets products for the six months ended March 31, 2021 was $2.8 million, an increase of $0.8 million, or 36.7%, from the corresponding period of the prior fiscal year.  The increase in operating income for both periods was primarily due to an increase in industrial product revenue and related gross profits, and operating expense reductions resulting from our fiscal year 2020 cost reduction program.

Emerging Markets

Revenue

Revenue from our Emerging Markets products for the three months ended March 31, 2021 was $0.2 million, compared to $0.4 million from the comparable period in prior fiscal year.  The decrease for the three months ended March 31, 2021 was primarily due to lower demand of border and perimeter security products from commercial customers.  Revenue from our Emerging Markets

26

products for the six months ended March 31, 2021 was $9.0 million, compared to $0.5 million from the prior fiscal year.  The increase in revenue for the six months ended March 31, 2021 was primarily attributable to the recognition of revenue related our contract with the CBP.   Quantum was awarded this contract during fiscal year 2020 to provide a technology solution to the Department of Homeland Security.  As of March 31, 2021, unrecognized revenue related to this contract was approximately $1.3 million, the majority of which is expected to be recognized in during the last half of fiscal year 2021.  

On January 20, 2021, President Biden ordered a pause on construction of the wall at the U.S. – Mexico border to assess the legality of the funding, contracting methods, as well as the consequences of stopping the construction. It remains uncertain at this time whether the executive order will result in a temporary halt or permanent cessation of the construction.  The new Biden administration may implement new or different policies or take further executive action regarding border security that could change the demand for our perimeter and security products.

Operating Income (Loss)

Operating loss from our Emerging Markets products for the three months ended March 31, 2021 was $(1.2) million, compared to $(2.5) million from corresponding period in the prior fiscal year.  The decrease in operating loss for the three months ended March 31, 2021 was primarily due to net non-cash adjustments of $1.5 million related to a decrease in the estimated fair value of contingent earn-out consideration related to the Quantum acquisition.  Operating income (loss) from our Emerging Markets products for the six months ended March 31, 2021 was $5.3 million, compared to a loss of $(3.9) million from corresponding period in the prior fiscal year.  The increase in operating income for the six months ended March 31, 2021 was primarily due to revenue and gross profits recognized on our contract with the CBP.  The increase was also due to net non-cash adjustments for the six months ended March 31, 2021 of $2.3 million related to a decrease in the estimated fair value of our contingent earn-out consideration.  Since its acquisition in July 2018, Quantum has primarily focused on product development activities, and the marketing of its technologies to government agencies and other end users.  

Liquidity and Capital Resources

At March 31, 2021, we had approximately $35.1 million in cash and cash equivalents and short-term investments.  For the six months ended March 31, 2021, we used $3.9 million of cash from operating activities.  Our net loss of $8.2 million was offset by net non-cash charges of $11.8 million resulting from deferred income taxes, depreciation, amortization, accretion, inventory obsolescence, stock-based compensation, bad debt expense and changes in the estimated fair value of contingent consideration.  Other uses of cash in our operations included (i) the removal of $4.2 million gross profit from the sale of used rental equipment as it is included in investing activities, (ii) a $6.7 million increase in inventories for the production of OBX products as well as the upgrade and repair of our OBX rental fleet, (iii) a $2.7 million increase in unbilled receivables related to our contract with CBP and (iv) a $4.2 million decrease in deferred revenue and other liabilities primarily due to the revenue recognized on the land-based wireless product that was delivered in the prior fiscal year.  Offsetting these uses of cash were (i) a $3.6 million increase in accounts payable due to the increase in inventories and the timing of payments to suppliers and (ii) a $6.5 million increase in deferred cost of revenue and other assets primarily due to recognition of cost of revenue on the land-based wireless product and the prepayment of annual insurance premiums.  

For the six months ended March 31, 2021, we generated cash of $4.7 million in investing activities.  Sources of cash included (i) $10.0 million of proceeds from the sale of used rental equipment and (ii) $0.3 million of proceeds from the transfer of our investment in a debt security.  Uses of cash included (i) disbursements of $3.8 million for purchases of short-term investment, $1.7 million for additions to our property, plant and equipment and (iii) $0.1 million for additions to our equipment rental fleet.   We expect our cash investments in property, plant and equipment during fiscal year 2021 to be approximately $3 million.  Depending on demand for our OBX marine rental equipment, we expect fiscal year 2021 cash investments into our rental fleet to be approximately $2 million.  Our capital expenditures are expected to be funded from our cash on hand, internal cash flows, cash flows from our rental contracts or, if necessary, borrowings under our credit agreement.

For the six months ended March 31, 2021, we used $2.3 million from financing activities for the purchase of treasury stock pursuant to a stock buy-back program authorized by our board of directors. The program authorizes us to repurchase up to $5 million of our common stock in open market transactions.  At March 31, 2021, approximately $2.7 million remains available for repurchases under the program.

Since 2014, the oil and gas industry has experienced a sustained downturn due to low oil and gas prices. The unprecedented sharp decline in crude oil prices since February 2020 has further impacted the overall condition of the oil and gas industry, stifling budgets targeted at the oil and gas exploration industry, including the seismic industry.  Prior to this downturn we saw some signs of increased seismic activity in certain areas around the world; however, we expect the need for new seismic equipment to remain restrained due to current industry conditions, capital limitations affecting many of our customers and excessive on-hand quantities of under-utilized customer-owned seismic equipment.  Further, we expect product sales of our Oil and Gas Markets products—specifically our legacy land-based traditional and wireless products—to remain low until the oil and gas industry begins to show signs of recovery and exploration-focused seismic activities increase.  Crude oil prices have recently rebounded to February 2020 levels;

27

however, oil and gas pricing and the resultant economic conditions may not recover meaningfully in the long term, and we expect these challenging industry conditions facing our Oil and Gas Markets products will continue in fiscal year 2021. 

On July 13, 2020, we received an interest in a senior secured bond from an international seismic marine customer.  Our interest in the bond, which has a face value of $13.0 million, was received in exchange for $13.0 million of unpaid invoices and late fees owed by the customer.   The bond is secured by a third in line lien on the assets owned by the customer and has an 8% interest rate with bi-annual interest and possible principal payments based on excess available cash flow.  Interest payments can be made either in cash or in-kind payments in the form of additional debt security.  In-kind interest payments require an 8.8% interest rate.  The bond matures on July 13, 2022.  The bond is listed on the Oslo Alternative Bond Market; however, the actual marketability is unknown at this time.  Based on the distressed financial condition of the customer, we believed the fair value of the bond was nominal. In January 2021, we transferred the bond pursuant to a purchase agreement (the “Agreement”) entered into with a third party (the “Buyer”).  Pursuant to the Agreement, we transferred the bond to the Buyer in exchange for non-refundable consideration of $0.3 million and will receive additional cash compensation of $2.4 million from the Buyer if certain terms and conditions between the Buyer and our customer are met by December 31, 2021.  In the event these terms and conditions are not met, we have the option to reacquire the bond from the Buyer for one US dollar ($1.00).    

   During the first quarter of fiscal year 2021, we entered into a $13.2 million short-term promissory note with a customer related to the sale of rental equipment and an outstanding receivable balance.   The note, which bore interest at 8% per annum, was paid during the three months ended March 31, 2021.

Our available cash and cash equivalents and short-term investments totaled $35.1 million at March 31, 2021, which included $5.3 million of cash and cash equivalents held by our foreign subsidiaries and branch offices.  The 2017 Tax Act creates new taxes on certain foreign earnings and also requires companies to pay a one-time transition tax on undistributed earnings of their foreign subsidiaries which were previously tax deferred.  We have determined that we are not required to pay any transition tax on the undistributed earnings of our foreign subsidiaries since we had no accumulated foreign earnings on a consolidated basis.

Our credit agreement allows for borrowings of up to $20.0 million with such amounts available for borrowing determined by a borrowing base.  In November 2019, we amended the credit agreement to (i) extend the maturity date from April 2020 to April 2022, (ii) increase the unencumbered liquid assets covenant threshold from $5 million to $10 million commencing with the fiscal quarter ending December 31, 2020 and for each fiscal quarter thereafter, (iii) increase the tangible net worth requirement from $140 million to $145 million commencing with the fiscal quarter ending December 31, 2020 and for each fiscal quarter thereafter and (iv) remove the requirement that we obtain the consent of Frost Bank prior to paying dividends or repurchasing stock so long as we are in compliance with the covenants of the credit agreement. In March 2021, we amended the credit agreement to reduce the maximum amount available for borrowing from $30 million to $20 million.  The March 2021 amendment also altered the tangible net worth requirement to decrease the minimum threshold from $145 million to $132 million commencing with the fiscal quarter ending March 31, 2021 and for each fiscal quarter thereafter. Additionally, the March 2021 amendment added a funded debt to EBITDA ratio financial covenant which requires us to maintain, for a twelve-month period ending on the last day of each fiscal quarter commencing with the fiscal quarter ended March 31, 2021, and for each fiscal quarter thereafter, a ratio of funded debt to EBITDA not exceeding 1.50 to 1.00.  The March 2021 amendment also amended the definition of “Eligible Accounts” to include certain unbilled receivables, and reduced the limit on the amount of “Eligible Inventory” that may be included in the borrowing base from $20 million to $15 million.  Although, we have no amounts outstanding under our credit agreement, we continue to monitor our compliance with the covenants in our credit agreement in order to maintain flexibility.  Should we fall below the required covenant amount, we may seek to amend our credit agreement or seek an alternative credit agreement in the future in order to maintain this flexibility.  Should we need to amend the facility or seek an alternative credit facility, we may not be able to obtain as favorable terms as the current agreement.

At March 31, 2021, we had no outstanding borrowings under the credit agreement and our borrowing availability under the credit facility as of March 31, 2021 was $18.5 million.  At March 31, 2021, we were in compliance with all covenants under the credit agreement.  We currently do not anticipate the need to borrow under the credit agreement; however, we may be required to do so if circumstances change.  

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 our credit agreement through its expiration in April 2022, leveraging or sale of real estate assets, sales of rental assets and other liquidity sources which may be available to us.  However, currently we believe that our cash, cash equivalents and borrowings under our credit facility will be sufficient to finance any future operating losses and planned capital expenditures through the next twelve months.  

Off-Balance Sheet Arrangements

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.

28

Contractual Obligations

Contingent Consideration

We recorded an initial contingent earn-out liability of $7.7 million in connection with our July 2018 acquisition of Quantum.   Subsequent to the acquisition, we reduced the estimated contingent earn-out liability to $5.0 million as of March 31, 2021.  Contingent payments, if any, may be paid in the form of cash or Company stock and will be derived from eligible revenue generated during the four-year post-acquisition period ending in July 2022.  We made cash earn-out payments of $0.1 million in fiscal year 2020 to the former shareholders of Quantum.  The Company plans to make an additional earn-out payment of approximately $2.3 million in the fourth quarter of fiscal year 2021. The maximum amount of contingent payments is $23.5 million.

We recorded an initial contingent earn-out liability of $4.3 million in connection with our November 2018 acquisition of all the intellectual property and related assets of the OptoSeis^® fiber optic sensing technology.  Subsequent to the acquisition, we increased the estimated contingent earn-out liability to $5.1 million as of March 31, 2021.  Contingent cash payments, if any, will be derived from eligible revenue generated during a five-and-a-half year post-acquisition earn-out period ending in May 2024.  No payments have been made to date related to the continent earn-out liability.  The maximum amount of contingent payments is $23.2 million.      

 We review and assess the fair value of our contingent earn-out liabilities on a quarterly basis.   See Note 13 to our consolidated financial statements in this Quarterly Report on Form 10-Q for more information on our contractual contingencies.

Critical Accounting Policies

Item 4.   Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining a system of disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified under the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”).  Notwithstanding the foregoing, there can be no assurance that our disclosure controls and procedures will detect or uncover all failures of persons within our Company and consolidated subsidiaries to report material information otherwise required to be set forth in our reports.

In connection with the preparation of this Quarterly Report on Form 10-Q, we carried out an evaluation under the supervision and with the participation of our management, including the CEO and CFO, as of March 31, 2021, of the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act.  Based on that evaluation, the CEO and CFO concluded that our disclosure controls and procedures were effective as of March 31, 2021.

Changes in Internal Control over Financial Reporting

There were no 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 March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Significant Accounting Policies

1.   Significant Accounting Policies

Basis of Presentation

The consolidated balance sheet of Geospace Technologies Corporation and its subsidiaries (the “Company”) at September 30, 2020 was derived from the Company’s audited consolidated financial statements at that date.  The consolidated balance sheet at March 31, 2021 and the consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for the three and six months ended March 31, 2021 and 2020 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 intercompany balances and transactions have been eliminated.  The results of operations for the three and six months ended March 31, 2021 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 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, 2020.

 Reclassifications

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

Use of 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.  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 bad debt reserves, collectability of rental revenue, inventory obsolescence reserves, self-insurance reserves, product warranty reserves, useful lives of long-lived assets, impairment of long-lived assets and intangible assets, contingent consideration, investment in debt security 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 March 31, 2021, cash and cash equivalents included $5.3 million held by the Company’s foreign subsidiaries and branch offices.  If the Company were to repatriate the cash held by its foreign subsidiaries, it could be required to accrue and pay taxes on any amount repatriated. The Tax Cut and Jobs Act (“2017 Tax Act”) creates new taxes on certain foreign earnings and also requires entities to pay a one-time transition tax on undistributed earnings of their foreign subsidiaries which were previously tax deferred.  The Company has determined it is not required to pay transition tax on the undistributed earnings of its foreign subsidiaries since it had no accumulated foreign earnings on a consolidated basis.

Recently Issued Accounting Pronouncements

 In June 2016, the Financial Accounting Standards Board (the “FASB”) issued guidance surrounding credit losses for financial instruments that replaces the incurred loss impairment methodology in generally accepted accounting principles.  The new impairment model requires immediate recognition of estimated credit losses expected to occur for most financial assets and certain other financial instruments.  For available-for-sale debt securities with unrealized losses, credit losses will be recognized as allowances rather than reductions in the amortized cost of the securities.  As a small reporting company, the Company must adopt this standard no later than the first quarter of its fiscal year ending September 30, 2024. Early adoption is permitted.  The standard’s provisions will be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting

period.  The Company intends to adopt this standard during the first quarter of its fiscal year ending September 30, 2024 and is continuing to evaluate the impact of this new guidance on its consolidated financial statements. 

In December 2019, the FASB issued guidance on simplifying the accounting for income taxes.  The guidance eliminates certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020.  Certain amendments within the guidance are required to be applied on a retrospective basis for all periods presented; others are to be applied using a modified retrospective approach with a cumulative-effect adjustment to retained earnings, if any, as of the beginning of the first reporting period in which the guidance is adopted; and yet others are to be applied using either basis. All other amendments not specified in the guidance should be applied on a prospective basis. Early adoption is permitted. An entity that elects to early adopt in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. The Company intends to adopt this standard during the first quarter of its fiscal year ending September 30, 2022 and is continuing to evaluate the new guidance to determine the impact it will have on its condensed consolidated financial statements.

Revenue From Contract With Customer [Abstract]

Revenue Recognition

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 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.  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.  Rental revenue is recognized as earned over the rental period if collectability of the rent is reasonably assured.  Rentals of the Company’s equipment generally range from daily rentals to minimum rental periods of up to six months or longer.  The Company has determined that ASC 606 does not apply to rental contracts, which are within the scope of ASC Topic 842, Leases.  

As permissible under the new standard, 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.

During the third quarter of fiscal year 2020, the Company was awarded a $10.5 million contract (inclusive of a subsequent contract amendment of $0.3 million) with the U.S. Customs and Border Protection (“CBP”) to provide a technology solution to the Department of Homeland Security.  Revenue recognized under the contract for fiscal year 2020 and for the six months ended March 31, 2021 was $0.3 million and $8.9 million, respectively.  The Company had unbilled receivables of $2.7 million at March 31, 2021 under this contract.  Unrecognized revenue for unsatisfied performance obligations on this contract at March 31, 2021 was approximately $1.3 million.  The Company anticipates the revenue on the remaining performance obligation on this contract will be recognized in fiscal year 2021.  Unsatisfied performance obligations on all other contracts held by the Company at March 31, 2021 had an original duration of one year or less.

At March 31, 2021, the Company had no deferred contract costs or deferred contract liabilities.  At September 30, 2020, the Company had no deferred contract costs and $0.2 million  deferred contract liabilities, which are included in current liabilities on the Company’s consolidated balance sheet as a component of deferred revenue and other liabilities.  During the three and six months ended March 31, 2021, no revenue and $0.2 million, respectively, was recognized from deferred contract liabilities.  During the three and six months ended March 31, 2020, no revenue was recognized from deferred contract liabilities.  No cost of revenue was recognized from deferred contract costs for the three and six months end March 31, 2021 and 2020.                                   

During the second quarter of fiscal year 2020, the Company partially financed a $12.5 million product sale by entering into a $10.0 million promissory note with the customer.  The note is for a three-year term with monthly principal and interest payments of $0.3 million.  Due to the financial condition of the customer, the Company had concerns over the probable collectability of the promissory note.  As a result, the Company did not recognize any revenue or cost of revenue on the product sale through its first quarter of fiscal year 2021. During the second quarter of fiscal year 2021, as a result of new information received from the customer, management determined that it is probable that the customer will satisfy its remaining payment obligations on the promissory note with the Company and recognized revenue of $12.5 million on the product sale.  The customer is current on its payment obligations and has made payments totaling $6.1 million (exclusive of interest) as of March 31, 2021 related to the product sale.           

For each of the Company’s operating segments, the following table presents revenue only from the sale of products and the performance of services under contracts with customers (in thousands).  Therefore, the table excludes all revenue earned from rental contracts.

3.   Investments

Short-term Investments

The Company classifies its short-term investments as available-for-sale securities.  Available-for-sale 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.  No realized gains or losses were recognized during the three and six months ended March 31, 2021 and 2020.  

The Company’s short-term investments were composed of the following (in thousands):

Short-term investments:
Corporate bonds	$	3,868	$	(3	)	$	—	$	3,865

The Company had no short-term investments at September 30, 2020.

The Company’s short-term investments had contractual maturities ranging from September 2021 to May 2022.

Investment in Debt Security

On July 13, 2020, the Company received an interest in a senior secured bond issued from an international seismic marine customer.  The Company’s interest in the bond, which has a face value of $13.0 million, was received in exchange for $13.0 million of unpaid invoices and late fees owed by the customer.  The bond is secured by a third in line lien on the assets owned by the customer and has an 8% interest rate with bi-annual interest and possible principal payments based on available excess cash flows.  Interest payments can be made either in cash or in-kind payments in the form of additional debt security.  In-kind interest payments require an 8.8% interest rate.  The bond matures on July 13, 2022. The bond is listed on the Oslo Alternative Bond Market; however, the actual marketability of the bond is unknown at this time.

Upon receipt of the senior secured bond, the Company performed a fair value assessment of the investment to determine the bond’s initial carrying amount.  In accordance with ASC 825, “Fair Value Instruments”, the Company has determined that the investment is a Level 3 financial instrument primarily due to its current unknown marketability.  Because of the distressed financial condition of the customer, the Company believes the fair value of the bond is nominal.

  In January 2021, the Company transferred the security pursuant to a purchase agreement (the “Agreement”) entered with a third party (the “Buyer”).   Pursuant to the Agreement, the Company received non-refundable consideration of $0.3 million and will receive additional cash compensation of $2.4 million from the Buyer if certain terms and conditions between the Buyer and the Company’s customer are met by December 31, 2021.  In the event these terms and conditions are not met, the Company has the option to reacquire the bond from the Buyer for one dollar US ($1.00).  The Company recognized a gain on investment of $0.3 million during the three months ended March 31, 2021 in connection with the transfer of the bond.

Fair Value of Financial Instruments

4.   Fair Value of Financial Instruments

The Company’s financial instruments generally include cash and cash equivalents, short-term investments, trade accounts, notes receivable and accounts payable.  Due to the short-term maturities of cash and cash equivalents, trade accounts, notes receivable and accounts payable, the carrying amounts of these financial instruments are deemed to approximate their fair value on the respective balance sheet dates.  The valuation technique used to measure the fair value of the contingent consideration was derived from models utilizing market observable inputs.  

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

The following tables present the fair value of the Company’s short-term investments and contingent consideration by valuation hierarchy and input (in thousands):

	As of March 31, 2021

Balance at December 31, 2020		10,265
Fair value adjustments		(221	)
Balance at March 31, 2021	$	10,044

Adjustments to the fair value of the contingent consideration are based on Monte Carlo simulations or the probability-weighted expected return method utilizing inputs which include market comparable information and management assessments regarding potential future scenarios.  The Company believes its estimates and assumptions are reasonable, however, there is significant judgment involved.

Trade accounts receivable	$	7,606		$	14,090
Allowance for doubtful accounts		(523	)		(496	)
Total	$	7,083		$	13,594

The allowance for doubtful accounts represents the Company’s best estimate of probable credit losses.  The Company determines the allowance based upon historical experience and a current review of its trade accounts receivable balances.  Trade accounts receivable balances are charged off against the allowance whenever it is probable that the receivable balance will not be recoverable.              

Notes receivable are reflected in the following table (in thousands):

	March 31, 2021			September 30, 2020
Notes receivable	$	6,525		$	184
Less current portion		(3,448	)		(184	)
Non-current notes receivable	$	3,077		$	—

Promissory notes receivable are generally collateralized by the products sold, and bear interest at rates ranging up to 8% per year.  The promissory notes receivable mature at various times through January 2023.  The Company has, on occasion, extended or renewed notes receivable as they mature, but there is no obligation to do so.

During the second quarter of fiscal year 2020, the Company partially financed a $12.5 million product sale by entering into a $10.0 million promissory note with the customer.  The note is for a three-year term with monthly principal and interest payments of $0.3 million.  Due to the financial condition of the customer, the Company had concerns over the probable collectability of the promissory note.  As a result, the note receivable was not reflected on the Company’s consolidated balance sheet through its first quarter of fiscal year 2021. During the second quarter of fiscal year 2021, as a result of a new information received from the customer, management determined that it is probable that the customer will satisfy its remaining payment obligations to the Company and has recognized the promissory note on its consolidated balance sheet as of March 31, 2021.  See Note 2 for more information on this matter.

During the first quarter of fiscal year 2021, the Company entered into a $13.2 million short-term promissory note with a customer related to the sale of rental equipment and an outstanding receivable balance.   The note, which bore interest at 8% per annum, was paid during the three months ended March 31, 2021.

As Lessor

The Company leases equipment to customers primarily for terms of six months or less.  All of the Company’s leasing arrangements as lessor are classified as operating leases.  The majority of the Company’s rental revenue is generated from its marine-based wireless seismic data acquisition system.

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.  The Company suspends revenue recognition when the collectability of amounts due are no longer probable and concurrently records a direct write-off of the lease receivable to rental revenue and limits future rental revenue recognition to cash received.  As of March 31, 2021, the Company had lease receivables from customers, net of reserves, of approximately $1.8 million.

Rental revenue for the three and six months ended March 31, 2021 was $2.3 million and $4.0 million, respectively.   Rental revenue for the three and six months ended March 31, 2020 was $16.4 million and $25.0 million, respectively.  

At March 31, 2021, future minimum lease obligations due from the Company’s leasing customers (all in fiscal year 2021) were $7.1 million.  

Rental equipment consisted of the following (in thousands):

	March 31, 2021			September 30, 2020
Rental equipment, primarily wireless recording equipment	$	90,399		$	114,783
Accumulated depreciation and impairment		(52,017	)		(60,466	)
	$	38,382		$	54,317

During the second quarter of fiscal year 2021, the Company entered into a memorandum of understanding with a customer to lease land-based wireless seismic rental equipment from its rental fleet.  The transaction is expected to be in the form of a sales-type lease with ownership of the equipment transferring to the customer upon completion of the lease, which has a term of six months.  The carrying amount of the equipment to be leased is $1.3 million and has been reclassified from rental equipment to assets held for sale on its consolidated balance sheet as of March 31, 2021.  Total lease payments due from the customer under the lease exceed the equipment’s carrying value.  The Company anticipates the transaction will be consummated during the third quarter of fiscal year 2021.

During the six months ended March 31, 2021, the Company issued 189,950 restricted stock units (“RSUs”) under its 2014 Long Term Incentive Plan, as amended (the “Plan”).  The RSUs issued include both time-based and performance-based vesting provisions.  The weighted average grant date fair value of each RSU was $6.96 per unit.  The grant date fair value of the RSUs was $1.3 million, which will be charged to expense over the next four years as the restrictions lapse.  Compensation expense for RSUs was

determined based on the closing market price of the Company’s stock on the date of grant applied to the total number of units that are anticipated to fully vest. Each RSU represents a contingent right to receive one share of the Company’s common stock upon vesting.  As of March 31, 2021, the Company had unrecognized compensation expense of $3.1 million relating to RSUs that is expected to be recognized over a weighted average period of 2.8 years.

As of March 31, 2021, the Company had $0.5 million of unrecognized compensation expense related to restricted stock awards (“RSAs”) that is expected to be recognized over a weighted average period of 0.9 years.

Contingent Consideration

In connection with its acquisitions of Quantum Technology Sciences, Inc. (“Quantum”) and the OptoSeis^® fiber optic sensing technology business, the Company recorded contingent purchase price payments, or contingent consideration, that may be owed in the future.  For both acquisitions, the contingent payments are based on future receipt of contract awards and the resulting revenue derived from such contracts.  The Company utilizes the services of independent valuation consultants to assist with the estimation of the fair value of this contingent consideration.  The determination of fair value is inherently unpredictable since it requires estimates and projections of future revenue, including the size, length, timing and, in the case of Quantum, the extent of gross profits earned under its future contracts.  As a result, the Company anticipates fair value adjustments to these liabilities over the respective earn-out periods, and these adjustments will result in either charges or credits to the Company’s operating expenses when the fair value of the contingent consideration increases or decreases, respectively.  

The Company recorded an initial contingent earn-out liability of $7.7 million in connection with its July 2018 acquisition of Quantum.   Contingent payments, if any, may be paid in the form of cash or Company stock and will be derived from eligible revenue generated during a four-year earn-out period ending July 2022.  The maximum amount of contingent payments is $23.5 million over the four-year earn-out period.  At September 30, 2020, the contingent earn-out liability was valued at $5.8 million.  During the six months ended March 31, 2021, the Company recorded an adjustment of $0.8 million to decrease the liability to an estimated fair value of $5.0 million.  The decrease in the earn-out liability for the six months ended March 31, 2021 was due to a decrease in projected eligible revenue.  The Company made a cash earn-out payment of $0.1 million in fiscal year 2020 to the former shareholders of Quantum.  The Company plans to make an additional earn-out payment of approximately $2.3 million in the fourth quarter of fiscal year 2021.       

The Company recorded an initial contingent earn-out liability of $4.3 million in connection with its November 2018 acquisition of all the intellectual property and related assets of the OptoSeis^® fiber optic sensing technology.  Contingent cash payments, if any, will be derived from eligible revenue generated during a five-and-a-half year earn-out period ending in May 2024.  The maximum amount of contingent payments is $23.2 million over the five-and-a-half year earn-out period.  At September 30, 2020, the contingent earn-out liability was valued at $5.2 million.  During the six months ended March 31, 2021, the Company recorded an adjustment of $0.1 million to decrease the liability to an estimated value of $5.1 million.      

 The Company reviews and assesses the fair value of its contingent earn-out liabilities on a quarterly basis.    

Operating Leases

The Company leases office space and certain equipment for terms of seven years or less.  As of March 31, 2021, future minimum lease payment obligations were $1.5 million.    

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 these pending matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

15.  Risks and Uncertainties   

Concentration of Credit Risk

As of March 31, 2021, the Company had combined trade accounts and notes receivable and unbilled receivables from three customers of $6.9 million, $4.2 million and $1.0 million.  During the six months ended March 31, 2021, revenue recognized from these three customers was $13.2 million, $12.7 million and $8.9 million, respectively.   

COVID-19 Pandemic

The ongoing COVID-19 pandemic has spread across the globe and has negatively impacted worldwide economic activity, including the global demand for oil and natural gas, and continues to create challenges in the Company’s markets.  In addition to measures the Company has taken voluntarily, the government authorities in the Company’s markets have taken actions to mitigate the spread of COVID-19, including travel restrictions, border closings, restrictions on public gatherings, stay-at-home orders and other quarantine and isolation measures. Following the initial outbreak of the virus, the Company experienced disruptions in its supply chain, a reduction in demand for certain products, cancellation of rental contracts and difficulty with field employees and salespeople traveling domestically and abroad to conduct the Company’s business. COVID-19 continues to pose the risk that the Company or its employees, contractors, suppliers and customers may be prevented from conducting business activities for an indefinite period of time, including potential spread of the disease within these groups or restrictions that may be requested or mandated by governmental authorities, including quarantines of certain geographic areas, restrictions on travel and other restrictions that prohibit employees from going to work, both around the world as well as in certain jurisdictions in the United States.  The continued spread of COVID–19 and the related mitigation measures have disrupted the Company’s supply chain, resulting in longer lead times in materials shipped from suppliers and extended the shipping time for these materials to reach the Company’s facilities.  If COVID–19 continues to spread or the response to contain the COVID–19 pandemic is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and liquidity.

Decrease in Oil Commodity Price Levels

Demand for many of the Company’s products and the profitability of its 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 the Company’s products.  Conversely, in periods when these energy commodity prices deteriorate, capital spending budgets of oil and natural gas operators tend to contract and the demand for the Company’s products generally weakens.  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 its 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, 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 OPEC to set and maintain production levels and prices of foreign imports.

Sustained low oil prices or the failure of oil prices to rise in the future and the resulting downturns or lack of growth in the energy industry and energy‑related business, could have a negative impact on the Company’s results of operations and financial condition. In light of the decline in oil prices caused by the COVID-19 pandemic in 2020, oil and gas exploration and production companies experienced a significant reduction in cash flows, which resulted in reductions in their capital spending budgets for oil and gas exploration-focused activities, including seismic data acquisition activities.  Demand for the sale of the Company’s seismic products targeted at customers in its Oil and Gas Markets segment, which has historically accounted for the majority of its revenue, significantly declined during fiscal year 2020, and both product sales and rental revenue could significantly diminish during the remainder of fiscal year 2021 or beyond as a result of significant uncertainty in the outlook for oil and gas exploration.  Specifically, the Company expects these challenging industry conditions to result in decreased demand for its marine wireless nodal products and its land-based seismic products, as the demand for such products has been, and will likely continue to be, vulnerable to downturns in the economy and the oil and gas industry in general.  In addition to the negative effects of slowdowns in the United States economy, slowing economic growth in growing economies like those in China and India could lead to a decline in demand for crude oil and natural gas.  Slowdowns in economic activity would likely reduce worldwide demand for energy and result in an extended period of lower crude oil and natural gas prices.  Any material changes in oil and gas prices or other market trends that adversely impact seismic exploration activity 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 the Company’s oil and gas products may be adversely affected when world supplies exceed demand.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The consolidated balance sheet of Geospace Technologies Corporation and its subsidiaries (the “Company”) at September 30, 2020 was derived from the Company’s audited consolidated financial statements at that date.  The consolidated balance sheet at March 31, 2021 and the consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for the three and six months ended March 31, 2021 and 2020 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 intercompany balances and transactions have been eliminated.  The results of operations for the three and six months ended March 31, 2021 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 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, 2020.

Reclassifications

 Reclassifications

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

Use of Estimates

Use of 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.  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 bad debt reserves, collectability of rental revenue, inventory obsolescence reserves, self-insurance reserves, product warranty reserves, useful lives of long-lived assets, impairment of long-lived assets and intangible assets, contingent consideration, investment in debt security 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

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, 2021, cash and cash equivalents included $5.3 million held by the Company’s foreign subsidiaries and branch offices.  If the Company were to repatriate the cash held by its foreign subsidiaries, it could be required to accrue and pay taxes on any amount repatriated. The Tax Cut and Jobs Act (“2017 Tax Act”) creates new taxes on certain foreign earnings and also requires entities to pay a one-time transition tax on undistributed earnings of their foreign subsidiaries which were previously tax deferred.  The Company has determined it is not required to pay transition tax on the undistributed earnings of its foreign subsidiaries since it had no accumulated foreign earnings on a consolidated basis.

Recently Issued Accounting Pronouncements

Recently Issued Accounting Pronouncements

 In June 2016, the Financial Accounting Standards Board (the “FASB”) issued guidance surrounding credit losses for financial instruments that replaces the incurred loss impairment methodology in generally accepted accounting principles.  The new impairment model requires immediate recognition of estimated credit losses expected to occur for most financial assets and certain other financial instruments.  For available-for-sale debt securities with unrealized losses, credit losses will be recognized as allowances rather than reductions in the amortized cost of the securities.  As a small reporting company, the Company must adopt this standard no later than the first quarter of its fiscal year ending September 30, 2024. Early adoption is permitted.  The standard’s provisions will be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting

period.  The Company intends to adopt this standard during the first quarter of its fiscal year ending September 30, 2024 and is continuing to evaluate the impact of this new guidance on its consolidated financial statements. 

In December 2019, the FASB issued guidance on simplifying the accounting for income taxes.  The guidance eliminates certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020.  Certain amendments within the guidance are required to be applied on a retrospective basis for all periods presented; others are to be applied using a modified retrospective approach with a cumulative-effect adjustment to retained earnings, if any, as of the beginning of the first reporting period in which the guidance is adopted; and yet others are to be applied using either basis. All other amendments not specified in the guidance should be applied on a prospective basis. Early adoption is permitted. An entity that elects to early adopt in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. The Company intends to adopt this standard during the first quarter of its fiscal year ending September 30, 2022 and is continuing to evaluate the new guidance to determine the impact it will have on its condensed consolidated financial statements.
