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 15—“Corporate 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.

In addition, the Company has a history of operating losses and has had negative cash from operating activities. However, as of July 31, 2021, the Company has no funded debt or obligations containing financial covenants, working capital of approximately $16.1 million, including cash of approximately $2.1 million, backlog of firm orders of approximately $11.7 million, the ability, and plans, to reduce costs to maintain positive cash flow, additional equity available to raise further capital, and lease pool equipment being actively marketed for sale. Based on these factors, management expects the Company to continue to meet its obligations as they arise over the next twelve months.

(“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.

Product Warranties Income Taxes 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 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 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.

Liquidity Disclosure [Abstract]
Liquidity	4. 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 • 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 expects nd ATM • 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.

We elected to apply the current period transition approach as introduced by ASU 2018-11 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.

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.

Share-based Payment Arrangement [Abstract]
Stock Option Plans	18. 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 in-flows.

Earnings Per Share [Abstract]
Earnings per Share	11. Earnings per Share Net income per basic common share is computed using the weighted average number of common shares outstanding during the period, excluding unvested restricted stock. Net income per diluted common share is computed using the weighted average number of common shares and dilutive potential common shares outstanding during the period using the treasury stock method. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect and from the The following table presents the calculation of basic and diluted weighted average common shares used in the earnings per share calculation: Three Months Ended Six Months Ended 2021 2020 2021 2020 (in thousands) (in thousands) Basic weighted average common shares outstanding 13,774 12,182 13,767 12,177 Stock options 79 3 58 1 Unvested restricted stock 29 10 18 5 Total weighted average common share equivalents 108 13 76 6 Diluted weighted average common shares outstanding 13,882 12,195 13,843 12,183 For the three and six months ended July 31, 2021 and 2020, 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.

Organization	Organization 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.

Income Taxes	Income Taxes 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 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	Fair Value of Financial Instruments — 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.
