Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Organization —MIND Technology, Inc., a Delaware corporation (the “Company”), formerly Mitcham Industries, Inc., a Texas corporation, was incorporated in 1987. Effective August 3, 2020 the Company effectuated a reincorporation to the state of Delaware. Concurrent with the reincorporation the name of the Company was changed to MIND Technology, Inc. and the number of shares of common stock and preferred stock authorized for issuance was increased. See Note 20 – Corporate Restructuring. The Company, through its wholly owned subsidiaries, Seamap Pte Ltd, MIND Maritime Acoustics, LLC (formerly Seamap USA, LLC), Seamap (Malaysia) Sdn Bhd and Seamap (UK) Ltd, collectively “Seamap”, and its wholly owned subsidiary, Klein Marine Systems, Inc. (“Klein”), designs, manufactures and sells a broad range of proprietary products for the seismic, hydrographic and offshore industries with product sales and support facilities based in Singapore, Malaysia, the United Kingdom and the states of New Hampshire and Texas. Prior to July 31, 2020, the Company, through its wholly owned Canadian subsidiary, Mitcham Canada, ULC (“MCL”), its wholly owned Hungarian subsidiary, Mitcham Europe Ltd. (“MEL”), and its branch operations in Colombia, provided full-service equipment leasing, sales and service to the seismic industry worldwide. Effective July 31, 2020, the Leasing Business has been classified as held for sale on the financial results reported as discontinued operations (see Note 2 – “Assets Held for Sale and Discontinued Operations” for additional details). All intercompany transactions and balances have been eliminated in consolidation. During February 2019, the Company completed the sale of its wholly owned Australian subsidiary, Seismic Asia Pacific Pty Ltd. (“SAP”) (see Note 23 - “Sale of Subsidiary” for additional details related to this transaction). Revenue Recognition of Marine Technology Product Sales —Revenues and cost of sales from the sale of marine technology products are recognized upon acceptance of terms and completion of our performance obligations, which is typically when delivery has occurred, barring any question as to collectability. Revenue Recognition of Long-term Projects —From time to time the Company enters into contracts whereby certain marine equipment is assembled or manufactured and sold, primarily to governmental entities. Performance under these contracts generally occurs over a period of three Revenue Recognition of Service Agreements —In some cases the Company provides on-going support services pursuant to contracts that generally have a term of 12 months. The Company recognizes revenue from these contracts ratably over the term of the contract. The Company may also provide support services on a time and material basis. Revenue from these arrangements is recognized as the services are provided. For certain new systems, the Company provides support services for up to 12 months at no additional charge. Any amounts attributable to these support obligations are immaterial. Revenues from service contracts for fiscal years ended 2021 and 2020 were not material and as a result are not presented separately in the financial statements. Revenue Recognition of Leasing Arrangements —The Company leases various types of seismic equipment to seismic data acquisition companies. All leases at January 31, 2021 and 2020 are for one year or less. Lease revenue is recognized ratably over the term of the lease. The Company does not enter into leases with embedded maintenance obligations. The standard lease provides that the lessee is responsible for maintenance and repairs to the equipment, excluding normal wear and tear. The Company occasionally provides technical advice to its customers without additional compensation as part of its customer service practices. Repairs or maintenance performed by the Company is charged to the lessee, generally on a time and materials basis. Repair and maintenance revenues are recognized as incurred. Effective July 31, 2020, the Leasing Business has been classified as held for sale on the financial results reported as discontinued operations (see Note 2 – “Assets Held for Sale and Discontinued Operations” for additional details). Allowance for Doubtful Accounts —Trade receivables are uncollateralized customer obligations due under normal trade terms. The carrying amount of trade receivables and contracts receivable is reduced by a valuation allowance that reflects management’s estimate of the amounts that will not be collected, based on the age of the receivable, payment history of the customer, general industry conditions, general financial condition of the customer and any financial or operational leverage the Company may have in a particular situation. Amounts are written-off when collection is deemed unlikely. Past due amounts are determined based on contractual terms. The Company generally does not charge interest on past due accounts. Cash and Cash Equivalents —The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Short-term Investments— The Company considers all highly liquid investments with an original maturity greater than three months, but less than twelve months, to be short-term investments. Inventories —Inventories are stated at the lower of cost or market. An allowance for obsolescence is maintained to reduce the carrying value of any materials or parts that may become obsolete. Inventories are periodically monitored to ensure that the allowance for obsolescence covers any obsolete items. Property and Equipment —Property and equipment is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the related estimated useful lives. The estimated useful lives of equipment range from three Intangible Assets —Intangible assets are carried at cost, net of accumulated amortization. Amortization is computed on the straight-line method (for customer relationships, the straight-line method is not materially different from other methods that estimate run off of the underlying customer base) over the estimated life of the asset. Proprietary rights, developed technology and amortizable tradenames are amortized over a 10 to 15-year period. Customer relationships are amortized over an eight-year period. Patents are amortized over an eight Impairment —The Company reviews its long-lived assets, including its amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable . In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. The Company performs an impairment test on goodwill and indefinite lived assets on an annual basis. The Company performs a qualitative review to determine if it is more likely than not that the fair value of our reporting units is greater their carrying value. If the Company is unable to conclude qualitatively that it is more likely than not that a reporting unit’s fair value exceeds its carrying value, then the Company performs a quantitative assessment of fair value of the reporting unit. The quantitative reviews involve significant estimates on the part of management. Product Warranties —Seamap provide its customers warranties against defects in materials and workmanship generally for a period of three months after delivery of the product. Klein also provides its customers with similar warranties against defects in material and workmanship for an approximate twelve months period subsequent to delivery of the product. The Company maintains an accrual for potential warranty costs based on historical warranty claims. For the fiscal years ended January 31, 2021 and 2020, warranty expense was not material. Income Taxes —The Company accounts for income taxes under the liability method, whereby the Company recognizes deferred tax assets and liabilities which represent differences between the financial and income tax reporting basis of its assets and liabilities. Deferred tax assets and liabilities are determined based on temporary differences between income and expenses reported for financial reporting and tax reporting. The Company has assessed, using all available positive and negative evidence, the likelihood that the deferred tax assets will be recovered from future taxable income. The weight given to the potential effect of positive and negative evidence is commensurate with the extent to which it can be objectively verified. The preponderance of negative or positive evidence supports a conclusion regarding the need for a valuation allowance for some portion, or all, of the deferred tax asset. The more significant types of evidence considered include the following: • projected taxable income in future years; • our history of taxable income within a particular jurisdiction; • any history of deferred tax assets expiring prior realization; • whether the carry forward period is so brief that it would limit realization of tax benefits; • other limitations on the utilization of tax benefits; • future sales and operating cost projections that will produce more than enough taxable income to realize the deferred tax asset based on existing sales prices and cost structures; • our earnings history exclusive of the loss that created the future deductible amount coupled with evidence indicating that the loss is an aberration rather than a continuing condition; and • tax planning strategies that will create additional taxable income. Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company’s management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, the allowance for doubtful accounts, lease pool valuations, valuation allowance on deferred tax assets, the evaluation of uncertain tax positions, estimated depreciable lives of fixed assets and intangible assets, impairment of fixed assets and intangible assets, valuation of assets acquired and liabilities assumed in business combinations and the valuation of stock options. Future events and their effects cannot be perceived with certainty. Accordingly, these accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results could differ from these estimates. Substantial judgment is necessary in the determination of the appropriate levels for the Company’s allowance for doubtful accounts because of the extended payment terms the Company offers to its customers on occasion and the limited financial wherewithal of certain of these customers. As a result, the Company’s allowance for doubtful accounts could change in the future, and such change could be material to the financial statements taken as a whole. The Company must also make substantial judgments regarding the valuation allowance on deferred tax assets and with respect to quantitative analysis prepared in conjunction with impairment analysis related to goodwill and other intangible assets. Fair Value of Financial Instruments — The Company’s financial instruments consist of accounts and contracts receivable and accounts payable. The Financial Accounting Standards Board (“FASB”) has issued guidance on the definition of fair value, the framework for using fair value to measure assets hierarchy, which prioritizes the inputs used to measure fair value. These tiers include: • Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current and contractual prices for the underlying instruments, as well as other relevant economic measures. • Level 3: Defined as pricing inputs that are unobservable form objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. The Company measures the fair values of goodwill, intangibles and other long-lived assets on a recurring basis if required by impairment tests applicable to these assets. The Company utilized Level 3 inputs to value intangibles and other long-lived assets as of January 31, 2021. See Notes 10 and 11 to our consolidated financial statements. Foreign Currency Translation —All balance sheet accounts of the Canadian resident subsidiary for fiscal 2021 and 2020, and for the United Kingdom resident subsidiaries for fiscal 2020, have been translated at the current exchange rate as of the end of the accounting period. Statements of operations items have been translated at average currency exchange rates. The resulting translation adjustment is recorded as a separate component of comprehensive income within stockholders’ equity. Stock-Based Compensation —Stock-based compensation expense is recorded based on the grant date fair value of share-based awards. Restricted stock awards are valued at the closing price on the date of grant. Determining the grant date fair value for options requires management to make estimates regarding the variables used in the calculation of the grant date fair value. Those variables are the future volatility of our common stock price, the length of time an optionee will hold their options until exercising them (the “expected term”), and the number of options that will be forfeited before they are exercised (the “forfeiture rate”). We utilize various mathematical models in calculating the variables. Share-based compensation expense could be different if we used different models to calculate the variables. Earnings Per Share —Net income (loss) per basic common share is computed using the weighted average number of common shares outstanding during the period. Net income (loss) per diluted common share is computed using the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect using the treasury stock method, from unvested shares of restricted stock using the treasury stock method and from outstanding common stock warrants. For the fiscal years ended January 31, 2021 and 2020, the following table sets forth the number of potentially dilutive shares that may be issued pursuant to options, restricted stock and warrants outstanding used in the per share calculations. Year Ended 2021 2020 (in thousands) Stock options 48 79 Restricted stock 17 3 Total dilutive shares 65 82 For the fiscal years ended January 31, 2021 and 2020, respectively, potentially dilutive common shares, underlying stock options and unvested restricted stock were anti-dilutive and were therefore not considered in calculating diluted loss per share for those periods. Reclassifications —Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no effect on the results of operations or comprehensive income.

Discontinued Operations and Disposal Groups [Abstract]
Assets Held for Sale and Discontinued Operations	Assets Held for Sale and Discontinued Operations On July 27, 2020, the Board determined to exit the Leasing Business.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Qualitative and quantitative disclosures are required, and optional practical expedients may be elected. This ASU is effective for the annual period beginning after December 15, 2018, including interim periods within that annual period. Subsequent amendments to the initial guidance have been issued in January 2017, January 2018, and July 2018 within ASU No. 201703, ASU No. 2018-01, ASU No. 2018-10, and ASU No. 2018-11 regarding qualitative disclosures, optional practical expedients, codification improvements and an optional transition method to adopt with a cumulative-effect adjustment versus a modified retrospective approach. These updates do not change the core principle of the guidance under ASU No. 2016-02, but rather provide implementation guidance. The Company adopted the accounting standard as of February 1, 2019, using the cumulative-effect transition method, which applies the guidance at the beginning of the period of adoption. The Company elected the package of practical expedients permitted, which, among other things, allowed the Company to carry forward the historical lease classification. In addition, the Company made the accounting policy elections to not recognize lease assets and lease liabilities with an initial term of 12 months or less and to not separate lease and non-lease components. The impact of adoption on the Company’s consolidated balance sheet was the recognition of a ROU asset of $3.0 million and an operating lease liability of $3.0 million, primarily for office and shop space leases that are currently off-balance sheet. The adoption did not have a material impact on its results of operations nor any material impact on its cash flows.

Liquidity

Liquidity Disclosure [Abstract]
Liquidity	Liquidity The global pandemic has created significant uncertainty in the global economy which could have a material adverse effect on the Company’s business, financial position, results of operations and liquidity. The time frame for which disruptions related to the pandemic will continue is uncertain as is the magnitude of any adverse impacts. We were required to temporarily shut-down our facilities in Malaysia and Singapore on March 17, 2020 and April 7, 2020, respectively. Both locations have now reopened and are operating at essentially full capacity. Our other facilities have been allowed to operate, although at reduced efficiencies, in some cases some employees have worked remotely. Management believes that any negative impacts will be temporary, but there can be no assurance of that. The Company has a history of operating losses and has had negative cash from operating activities. The above factors create substantial uncertainty regarding the Company’s future financial results and liquidity. Management has identified the following mitigating factors regarding adequate liquidity and capital resources to meet its obligations.: • The Company has no funded debt, excluding the PPP Loan granted to Klein which has been completely forgiven in February 2021, or other outstanding obligations, outside of normal trade obligations. • The Company has no obligations or agreements containing “maintenance type” financial covenants. • The Company has working capital of approximately $19.0 million as of January 31, 2021, including cash of approximately $4.6 million. • Should revenues be less than projected, the Company believes it is able, and has plans, to reduce costs proportionately in order to maintain positive cash flow. • The majority of the Company’s costs are variable in nature, such as raw materials and personnel related costs. The Company has already terminated or furloughed certain employees and contractors. • The Company has a backlog of orders of approximately $14.2 million (unaudited) as of January 31, 2021, as compared to approximately $8.9 million (unaudited) as of January 31, 2020. Production for certain of these orders was in process and included in inventory as of January 31, 2021, thereby reducing the liquidity needed to complete the orders. • Despite difficulties in world energy markets, the Company has been able to generate cash from the sale of lease pool equipment and collection of accounts receivable related to its discontinued operations. Management expects to generate additional liquidity from the sale of lease pool equipment in fiscal 2022. • The Company has declared the quarterly dividend on the its Series A Preferred Stock for the quarter ending April 30, 2021, but such quarterly dividends could be suspended in the future. • Despite the challenging economic environment in the year ended January 31, 2021, the Company was successful expanding its authorized capital stock (See Note 20 - Corporate Restructuring) and raising approximately $4.6 million in new capital through the sale of common and preferred stock pursuant to the 2 nd ATM offering program. Management expects to be able to raise further capital through the 2 nd ATM offering program should the need arise. • Based on publicized transactions and discussions with potential funding sources, Management believes that other sources of debt and equity financing are available should the need arise. For the factors discussed above, Management expects the Company to continue to meet its obligations as they arise over the next twelve months.

Leases

Leases [Abstract]
Leases	Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) which was modified by subsequently issued ASUs 2018-01, 2018-10, 2018-11 and 2018-20 (collectively the “New Lease Standard”). The New Lease Standard requires organizations that lease assets (“lessees”) to recognize the assets and liabilities of the rights and obligations created by leases with terms of more than 12 months. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee remains dependent on its classification as a finance or operating lease. The New Lease Standard also requires additional disclosure of the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The New Lease Standard was effective for financial statements issued for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”). ASU 2018-11 provided additional relief in the comparative reporting requirements for initial adoption of the New Lease Standard. Prior to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 provided an additional transition method allowing entities to initially apply the New Lease Standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. The Company adopted the New Lease Standard effective February 1, 2019. We elected to apply the current period transition approach as introduced by ASU 2018-11 and we elected to apply the following practical expedients and accounting policy decisions. We elected a package of transition expedients, which must be elected together, that allowed us to forgo reassessing certain conclusions reached under ASC 840. All expedients in this package were applied together for all leases that commenced before the effective date, February 1, 2019, of the adoption of the New Lease Standard. As a result, in transitioning to the New Lease Standard, for existing leases as of February 1, 2019, we continued to use judgments made under ASC 840 related to embedded leases, lease classification and accounting for initial direct costs. In addition, we have chosen, as an accounting policy election by class of underlying asset, not to separate non-lease components from the associated lease for all our leased asset classes, excluding for Real Estate related leases. As a result, for classes of Automobiles, Office Equipment and Manufacturing Equipment, we account for each separate lease component and the non-lease components associated with that lease as a single lease component. The Company has certain non-cancelable operating lease agreements for office, production and warehouse space in Texas, Hungary, Singapore, Malaysia, United Kingdom and Canada. Adoption of the New Lease Standard did have a material impact on our consolidated balance sheet as we recorded right-of-use assets and the corresponding lease liabilities related to our operating leases of approximately $3.0 million, each. The Company determined to treat lease costs with an original maturity of less than one year as short-term lease costs and did not record a right-of-use asset or related lease liability for these leases. The new standard did not have a material impact on our consolidated statements of operations or our statements of cash flows. Lease expense for the twelve months ended January 31, 2021 and 2020 was approximately $828,000 and $1.2 million, respectively, and was recorded as a component of operating loss. Included in these costs was short-term lease expense of approximately $20,000 and $30,000 for the twelve months ended January 31, 2021 and 2020, respectively. Supplemental balance sheet information related to leases as of January 31, 2021 and 2020 was as follows (in thousands): As of January 31, Lease 2021 2020 Assets Operating lease assets $ 1,471 $ 2,300 Liabilities Operating lease liabilities $ 1,471 $ 2,300 Classification of lease liabilities Current liabilities $ 1,008 $ 1,339 Non-current liabilities 463 961 Total Operating lease liabilities $ 1,471 $ 2,300 Lease-term and discount rate details as of January 31, 2021 and 2020 were as follows: As of January 31, Lease term and discount rate 2021 2020 Weighted average remaining lease term (years) Operating leases 1.09 1.76 Weighted average discount rate: Operating leases 10 % 9.27 % The incremental borrowing rate was calculated using the Company’s weighted average cost of capital.

These leases were generally renewable on a month-to-month basis. All taxes (other than income taxes) and assessments were the contractual responsibility of the lessee. To the extent that foreign taxes were not paid by the lessee, the relevant foreign taxing authorities might seek to collect such taxes from the Company. Under the terms of its lease agreements, any amounts paid by the Company to such foreign taxing authorities may be billed and collected from the lessee. The Company is not aware of any foreign tax obligations as of January 31, 2021 and 2020 that are not reflected in the accompanying consolidated financial statements. The Company leases its office and warehouse facilities in Canada, Texas, Singapore, United Kingdom, Hungary and Malaysia under operating leases. Facility lease expense for the fiscal years ended January 31, 2021 and 2020 was approximately $1.2 million and $1.2 million, respectively.

Based on a review of qualitative factors it was determined it was more likely than not that the fair value of our Seamap reporting unit was greater than its carrying value. Based on a review of qualitative and quantitative factors it was determined it was more likely than not that the fair value of our Klein reporting unit was greater than its carrying value. Accordingly, we did not record an impairment charge related to intangible assets in the Seamap and Klein reporting units. Due to the economic impact of the global pandemic, the decline in oil prices during the three months ended April 30, 2020 and a decline in the market value of the Company’s equity securities, the Company performed a quantitative review of the Seamap reporting unit and concluded that goodwill had been impaired. As a result, the Company recorded an impairment expense of approximately $2.5 million related to goodwill in the Seamap reporting unit during the quarter ended April 30, 2020. As of January 31, 2020, the Company completed its annual review of goodwill and indefinite lived intangible assets. Based on a review of qualitative factors it was determined it was more likely than not that the fair value of our Seamap reporting unit was greater than its carrying value. Based on a review of qualitative and quantitative factors it was determined it was more likely than not that the fair value of our Klein reporting unit was not greater than its carrying value. Accordingly, we recorded an impairment of approximately $760,000 related to indefinite lived intangible assets in the Klein reporting unit. Aggregate amortization expense was $1.8 million, and $1.8 million for the fiscal years ended January 31, 2021 and 2020, respectively.

Related Party Transaction	Related Party Transaction On October 7, 2016, the Company entered into an equity distribution agreement with Ladenburg Thalmann & Co. Inc. (the “Agent”). On December 18, 2019, the Company and Agent entered into an Amended and Restated equity distribution agreement (the “1 st Equity Distribution Agreement”). Pursuant to the 1 st Equity Distribution Agreement, the Company may sell up to 500,000 shares of the Series A Preferred Stock through the Agent through the 1 st ATM offering program. The Co-Chief Executive Officer and Co-President of the Agent is the Non-Executive Chairman of the Board. Under the Equity Distribution Agreement, the Agent was entitled to compensation of up to 2.0% of the gross proceeds from the sale of Series A Preferred Stock under the 1 st ATM offering program. As of January 31, 2021, we had issued 994,046 shares which represent 100% of the Series A Preferred Stock available for sale through the 1 st Equity Distribution Agreement. In September 2020 we entered into a new equity distribution agreement (the “2 nd Equity Distribution Agreement”) with the Agent with economic terms essentially identical to the initial agreement. Pursuant to the 2 nd Equity Distribution Agreement, the Company may sell up to 500,000 shares of Preferred Stock and 5,000,000 shares of $0.01 par value common stock (“Common Stock”) through the 2 nd ATM offering program.

Gross proceeds from these sales were approximately $1.0 million and the Agent received compensation of approximately $20,408, resulting in net proceeds to the Company of $1.0 million for the twelve months ended January 31, 2021. The Non-Executive Chairman of the Company received no portion of this compensation. For the twelve months ended January 31, 2021, the Company issued 1,584,556 shares of Common Stock under the 2 nd ATM offering program. Gross proceeds from these sales were approximately $4.0 million, the Agent received compensation of approximately $79,307 resulting in net proceeds to the Company, after deducting underwriting discounts and offering costs, of approximately $3.6 million for the twelve months ended January 31, 2021.

The CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The Company does not believe the CARES Act will have a material impact on the Company’s future income tax expense or the related tax assets and liabilities. The Company has determined that, due to the potential requirement for additional investment and working capital to achieve its objectives, the undistributed earnings of foreign subsidiaries as of January 31, 2021, are not deemed indefinitely reinvested outside of the United States. Furthermore, the Company has concluded that any deferred taxes with respect to the undistributed foreign earnings would be immaterial, particularly in light of the one-time repatriation of foreign earnings imposed by the TCJA and recorded in fiscal 2019. Therefore, the Company has not recorded a deferred tax liability associated with the undistributed foreign earnings as of January 31, 2021. Included in deferred tax assets is approximately $700,000 related to stock-based compensation, including non-qualified stock options. A significant number of stock options expired during fiscal 2021 because the market price of the Company’s common stock remained below the exercise price of these options. Recent market prices for the Company’s common stock remain below the exercise price of a number of options outstanding as of January 31, 2021. Should the market price of the Company’s common stock remain below the exercise price of the options, these stock options will expire without exercise. In accordance with the provisions of ASC 718-740-10, a valuation allowance has not been computed based on the decline in stock price. As of January 31, 2021, the Company has recorded valuation allowances of approximately $20.2 million related to deferred tax assets for continuing operations. These deferred tax assets relate primarily to net operating loss carryforwards in the United States and other jurisdictions. The valuation allowances were determined based on management’s judgment as to the likelihood that the deferred tax assets would not be realized. The judgment was based on an evaluation of available evidence, both positive and negative. At January 31, 2021, the Company had tax credit carry forwards for continuing operations of approximately $139,000, which amounts can be carried forward through at least 2026. As of January 31, 2021, and 2020 the company had no unrecognized tax benefits attributable to uncertain tax positions. The Company recognizes interest and penalties related to income tax matters as a component of income tax expense. The Company files U.S. federal income tax returns as well as separate returns for its foreign subsidiaries within their local jurisdictions. The Company’s U.S. federal tax returns are subject to examination by the IRS for fiscal years ended January 31, 2017 through 2021. The Company’s tax returns may also be subject to examination by state and local revenue authorities for fiscal years ended January 31, 2015 through 2021. The Company’s Singapore income tax returns are subject to examination by the Singapore tax authorities for fiscal years ended January 31, 2015 through 2021. The Company’s tax returns in other foreign jurisdictions are generally subject to examination for the fiscal years ended January 31, 2015 through January 31, 2021.

Share-based Payment Arrangement [Abstract]
Stock Option Plans	Stock Option Plans At January 31, 2021, the Company had stock-based compensation plans as described in more detail below. The total compensation expense related to stock-based awards granted under these plans during the fiscal years ended January 31, 2021 and 2020 was approximately $708,000 and $854,000, respectively. The Company recognizes stock-based compensation costs net of a forfeiture rate for only those awards expected to vest over the requisite service period of the award. The Company estimates the forfeiture rate based on its historical experience regarding employee terminations and forfeitures. The fair value of each option award is estimated as of the date of grant using a Black-Scholes-Merton option pricing formula. Expected volatility is based on historical volatility of the Company’s stock over a preceding period commensurate with the expected term of the option. The expected term is based upon historical exercise patterns. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yield was not considered in the option pricing formula since the Company does not pay dividends and has not paid any dividends since its incorporation. The weighted average grant-date fair value of options granted during the fiscal years ended January 31, 2021 and 2020 were $0.70 and $1.77, respectively. The assumptions for the periods indicated are noted in the following table. Weighted average Black-Scholes-Merton fair value assumptions Year Ending January 31, 2021 2020 Risk free interest rate 0.34% - 0.37% 1.47% - 2.53% Expected life 3.97 years - 5.97 years 3.98 years - 6.00 years Expected volatility 53% - 64% 49% - 51% Expected dividend yield 0.0% 0.0% Cash flows resulting from tax benefits attributable to tax deductions in excess of the compensation expense recognized for those options (excess tax benefits) are classified as financing out-flows and operating in-flows. The Company had no excess tax benefits during the fiscal years ended January 31, 2021 and 2020. The Company has share-based awards outstanding under, the MIND Technology, Inc. Stock Awards Plan (“the Plan”). Stock options granted and outstanding under the Plan generally vest evenly over three years and have a 10-year contractual term. The exercise price of a stock option generally is equal to the fair market value of the Company’s common stock on the option grant date. As of January 31, 2021, there were approximately 615,000 shares available for grant under the Plan. The Plan provides for awards of nonqualified stock options, incentive stock options, restricted stock awards, restricted stock units and phantom stock. New shares are issued upon vesting for restricted stock and upon exercise for options. Stock Based Compensation Activity The following table presents a summary of the Company’s stock option activity for the fiscal year ended January 31, 2021: Number of Weighted Weighted Aggregate Outstanding, January 31, 2020 2,440 $ 4.51 7.08 $ 20 Granted 320 1.47 Exercised — — Forfeited (41) 4.63 Expired (133) 5.31 Outstanding, January 31, 2021 2,586 $ 4.09 6.58 $ 223 Exercisable at January 31, 2021 1,778 $ 4.63 5.71 $ — Vested and expected to vest at January 31, 2021 2,562 $ 4.12 6.55 $ 213 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the fourth quarter of fiscal 2021 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on January 31, 2021. This amount changes based upon the market value of the Company’s common stock. No options were exercised during fiscal year ended January 31, 2021. There was no intrinsic value of the 9,000 options exercised during the fiscal year ended January 31, 2020. The fair value of options that vested during the fiscal years ended January 31, 2021 and 2020 was approximately $950,000 and $650,000, respectively. For the fiscal year ended January 31, 2021, approximately 500,000 options vested. As of January 31, 2021, there was approximately $482,228 of total unrecognized compensation expense related to unvested stock options granted under the Company’s share-based compensation plans. That expense is expected to be recognized over a weighted average period of 1.3 years. Restricted stock as of January 31, 2021 and changes during the fiscal year ended January 31, 2021 were as follows: Year Ended January 31, 2021 Number of Weighted Average Unvested, beginning of period 37 $ 3.98 Granted 15 1.25 Vested (12) 3.98 Canceled — — Unvested, end of period 40 $ 2.94 As of January 31, 2021, there was approximately no unrecognized stock-based compensation expense related to unvested restricted stock awards.

(“Klein”), designs, manufactures and sells a broad range of proprietary products for the seismic, hydrographic and offshore industries with product sales and support facilities based in Singapore, Malaysia, the United Kingdom and the states of New Hampshire and Texas. Prior to July 31, 2020, the Company, through its wholly owned Canadian subsidiary, Mitcham Canada, ULC (“MCL”), its wholly owned Hungarian subsidiary, Mitcham Europe Ltd. (“MEL”), and its branch operations in Colombia, provided full-service equipment leasing, sales and service to the seismic industry worldwide. Effective July 31, 2020, the Leasing Business has been classified as held for sale on the financial results reported as discontinued operations (see Note 2 – “Assets Held for Sale and Discontinued Operations” for additional details). All intercompany transactions and balances have been eliminated in consolidation. During February 2019, the Company completed the sale of its wholly owned Australian subsidiary, Seismic Asia Pacific Pty Ltd. (“SAP”) (see Note 23 - “Sale of Subsidiary” for additional details related to this transaction).
Revenue Recognition of Marine Technology Product Sales, Long-term Projects, and Service Agreements	Revenue Recognition of Marine Technology Product Sales —Revenues and cost of sales from the sale of marine technology products are recognized upon acceptance of terms and completion of our performance obligations, which is typically when delivery has occurred, barring any question as to collectability. Revenue Recognition of Long-term Projects —From time to time the Company enters into contracts whereby certain marine equipment is assembled or manufactured and sold, primarily to governmental entities. Performance under these contracts generally occurs over a period of three Revenue Recognition of Service Agreements —In some cases the Company provides on-going support services pursuant to contracts that generally have a term of 12 months. The Company recognizes revenue from these contracts ratably over the term of the contract. The Company may also provide support services on a time and material basis. Revenue from these arrangements is recognized as the services are provided. For certain new systems, the Company provides support services for up to 12 months at no additional charge. Any amounts attributable to these support obligations are immaterial. Revenues from service contracts for fiscal years ended 2021 and 2020 were not material and as a result are not presented separately in the financial statements.
Revenue Recognition of Leasing Arrangements	Revenue Recognition of Leasing Arrangements —The Company leases various types of seismic equipment to seismic data acquisition companies. All leases at January 31, 2021 and 2020 are for one year or less. Lease revenue is recognized ratably over the term of the lease. The Company does not enter into leases with embedded maintenance obligations. The standard lease provides that the lessee is responsible for maintenance and repairs to the equipment, excluding normal wear and tear. The Company occasionally provides technical advice to its customers without additional compensation as part of its customer service practices. Repairs or maintenance performed by the Company is charged to the lessee, generally on a time and materials basis. Repair and maintenance revenues are recognized as incurred. Effective July 31, 2020, the Leasing Business has been classified as held for sale on the financial results reported as discontinued operations (see Note 2 – “Assets Held for Sale and Discontinued Operations” for additional details).
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts —Trade receivables are uncollateralized customer obligations due under normal trade terms. The carrying amount of trade receivables and contracts receivable is reduced by a valuation allowance that reflects management’s estimate of the amounts that will not be collected, based on the age of the receivable, payment history of the customer, general industry conditions, general financial condition of the customer and any financial or operational leverage the Company may have in a particular situation. Amounts are written-off when collection is deemed unlikely. Past due amounts are determined based on contractual terms. The Company generally does not charge interest on past due accounts.
Cash and Cash Equivalents	Cash and Cash Equivalents —The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.
Short-term Investments	Short-term Investments— The Company considers all highly liquid investments with an original maturity greater than three months, but less than twelve months, to be short-term investments.
Inventories	Inventories —Inventories are stated at the lower of cost or market. An allowance for obsolescence is maintained to reduce the carrying value of any materials or parts that may become obsolete. Inventories are periodically monitored to ensure that the allowance for obsolescence covers any obsolete items.
Property and Equipment	Property and Equipment —Property and equipment is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the related estimated useful lives. The estimated useful lives of equipment range from three
Intangible Assets	Intangible Assets —Intangible assets are carried at cost, net of accumulated amortization. Amortization is computed on the straight-line method (for customer relationships, the straight-line method is not materially different from other methods that estimate run off of the underlying customer base) over the estimated life of the asset. Proprietary rights, developed technology and amortizable tradenames are amortized over a 10 to 15-year period. Customer relationships are amortized over an eight-year period. Patents are amortized over an eight
Impairment	Impairment —The Company reviews its long-lived assets, including its amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable .
Product Warranties	Product Warranties—Seamap provide its customers warranties against defects in materials and workmanship generally for a period of three months after delivery of the product. Klein also provides its customers with similar warranties against defects in material and workmanship for an approximate twelve months period subsequent to delivery of the product. The Company maintains an accrual for potential warranty costs based on historical warranty claims.
Income Taxes	Income Taxes —The Company accounts for income taxes under the liability method, whereby the Company recognizes deferred tax assets and liabilities which represent differences between the financial and income tax reporting basis of its assets and liabilities. Deferred tax assets and liabilities are determined based on temporary differences between income and expenses reported for financial reporting and tax reporting. The Company has assessed, using all available positive and negative evidence, the likelihood that the deferred tax assets will be recovered from future taxable income. The weight given to the potential effect of positive and negative evidence is commensurate with the extent to which it can be objectively verified. The preponderance of negative or positive evidence supports a conclusion regarding the need for a valuation allowance for some portion, or all, of the deferred tax asset. The more significant types of evidence considered include the following: • projected taxable income in future years; • our history of taxable income within a particular jurisdiction; • any history of deferred tax assets expiring prior realization; • whether the carry forward period is so brief that it would limit realization of tax benefits; • other limitations on the utilization of tax benefits; • future sales and operating cost projections that will produce more than enough taxable income to realize the deferred tax asset based on existing sales prices and cost structures; • our earnings history exclusive of the loss that created the future deductible amount coupled with evidence indicating that the loss is an aberration rather than a continuing condition; and • tax planning strategies that will create additional taxable income.
Use of Estimates	Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company’s management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, the allowance for doubtful accounts, lease pool valuations, valuation allowance on deferred tax assets, the evaluation of uncertain tax positions, estimated depreciable lives of fixed assets and intangible assets, impairment of fixed assets and intangible assets, valuation of assets acquired and liabilities assumed in business combinations and the valuation of stock options. Future events and their effects cannot be perceived with certainty. Accordingly, these accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results could differ from these estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments — The Company’s financial instruments consist of accounts and contracts receivable and accounts payable. The Financial Accounting Standards Board (“FASB”) has issued guidance on the definition of fair value, the framework for using fair value to measure assets hierarchy, which prioritizes the inputs used to measure fair value. These tiers include: • Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current and contractual prices for the underlying instruments, as well as other relevant economic measures. • Level 3: Defined as pricing inputs that are unobservable form objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.
Foreign Currency Translation	Foreign Currency Translation —All balance sheet accounts of the Canadian resident subsidiary for fiscal 2021 and 2020, and for the United Kingdom resident subsidiaries for fiscal 2020, have been translated at the current exchange rate as of the end of the accounting period. Statements of operations items have been translated at average currency exchange rates. The resulting translation adjustment is recorded as a separate component of comprehensive income within stockholders’ equity.
Stock-Based Compensation	Stock-Based Compensation —Stock-based compensation expense is recorded based on the grant date fair value of share-based awards. Restricted stock awards are valued at the closing price on the date of grant. Determining the grant date fair value for options requires management to make estimates regarding the variables used in the calculation of the grant date fair value. Those variables are the future volatility of our common stock price, the length of time an optionee will hold their options until exercising them (the “expected term”), and the number of options that will be forfeited before they are exercised (the “forfeiture rate”). We utilize various mathematical models in calculating the variables. Share-based compensation expense could be different if we used different models to calculate the variables.
Earnings Per Share	Earnings Per Share—Net income (loss) per basic common share is computed using the weighted average number of common shares outstanding during the period. Net income (loss) per diluted common share is computed using the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect using the treasury stock method, from unvested shares of restricted stock using the treasury stock method and from outstanding common stock warrants.
Reclassifications	Reclassifications —Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no effect on the results of operations or comprehensive income.
New Accounting Pronouncements	New Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Qualitative and quantitative disclosures are required, and optional practical expedients may be elected. This ASU is effective for the annual period beginning after December 15, 2018, including interim periods within that annual period. Subsequent amendments to the initial guidance have been issued in January 2017, January 2018, and July 2018 within ASU No. 201703, ASU No. 2018-01, ASU No. 2018-10, and ASU No. 2018-11 regarding qualitative disclosures, optional practical expedients, codification improvements and an optional transition method to adopt with a cumulative-effect adjustment versus a modified retrospective approach. These updates do not change the core principle of the guidance under ASU No. 2016-02, but rather provide implementation guidance. The Company adopted the accounting standard as of February 1, 2019, using the cumulative-effect transition method, which applies the guidance at the beginning of the period of adoption. The Company elected the package of practical expedients permitted, which, among other things, allowed the Company to carry forward the historical lease classification. In addition, the Company made the accounting policy elections to not recognize lease assets and lease liabilities with an initial term of 12 months or less and to not separate lease and non-lease components. The impact of adoption on the Company’s consolidated balance sheet was the recognition of a ROU asset of $3.0 million and an operating lease liability of $3.0 million, primarily for office and shop space leases that are currently off-balance sheet. The adoption did not have a material impact on its results of operations nor any material impact on its cash flows.
