Nature of Operations [Text Block]

1. Organization and Liquidity

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.

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 (the “Leasing Business”). Effective July 31, 2020, the Leasing Business has been classified as held for sale and the financial results reported as discontinued operations (see Note 3 – “Assets Held for Sale and Discontinued Operations” for additional details). All intercompany transactions and balances have been eliminated in consolidation.

These condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the discharge of liabilities in the normal course of business for the foreseeable future. The Company has a history of generating losses and negative cash from operating activities and may not have access to sources of capital that were available in prior periods. In addition, the lingering impacts of the global pandemic, emerging supply chain disruptions and recent volatility in oil prices have 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. Accordingly, substantial doubt has arisen regarding the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result should the Company not be able to continue as a going concern.

Management has identified the following mitigating factors regarding adequate liquidity and capital resources to meet its obligations:

•

The Company has no funded debt, 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 $15.6 million as of July 31, 2022, including cash of approximately $833,000.

•

Should revenues be less than projected, the Company believes it is able, and has plans in place, 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 recently eliminated two executive level positions, and additional reductions in operations, sales, and general and administrative headcount could be made, if deemed necessary by management.

•

The Company has a backlog of orders of approximately $19.3 million as of July 31, 2022. Production for certain of these orders was in process and included in inventory as of July 31, 2022, 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 2023.

•

The Company declared and paid the quarterly dividend on its Preferred Stock for the first quarter of fiscal 2023, and each quarter in fiscal 2022, but deferred payment of the quarterly dividend for the second quarter of fiscal 2023. The Company also has the option to defer future quarterly dividend payments if deemed necessary. The dividends are a cumulative dividend that accrue for payment in the future. During a deferral period, the Company is prohibited from paying dividends or distributions on its common stock, or redeeming any of those shares. Further, if the Company does not pay dividends on its Series A Preferred Stock for six or more quarters, the holders of Series A Preferred Stock will have the right to appoint two directors to the Company's board.

•

In recent years, the Company has raised capital through the sale of Common Stock and Preferred Stock pursuant to the ATM Offering Program (as defined herein) and underwritten offerings on Form S-1. Currently, the Company is not eligible to issue securities pursuant to Form S-3 and accordingly cannot sell securities pursuant to the ATM Offering Program. However, the Company may sell securities pursuant to Form S-1 or in private transactions. Management expects to be able to raise further capital through these available means should the need arise.

Notwithstanding the mitigating factors identified by management, there remains substantial doubt regarding the Company's ability to meet its obligations as they arise over the next twelve months.

2. Basis of Presentation and Immaterial Correction of Comprehensive Loss

The condensed consolidated balance sheet as of January 31, 2022, for the Company has been derived from audited consolidated financial statements. The unaudited interim condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2022 (“fiscal 2022”). In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position as of July 31, 2022, the results of operations for the three and six months ended July 31, 2022 and 2021, the cash flows for the six months ended July 31, 2022 and 2021, and the statement of stockholders’ equity for the three and six months ended July 31, 2022 and 2021, have been included in these condensed consolidated financial statements. The foregoing interim results are not necessarily indicative of the results of operations to be expected for the full fiscal year ending January 31, 2023 (“fiscal 2023”).

The Company has corrected an immaterial error in the statements of comprehensive loss for the three and six months ended July 31, 2021, which as previously presented, incorrectly included $682,000 and $1.3 million of preferred dividends as a component of comprehensive loss, respectively. Additionally, during the years ended January 31, 2022 and 2021, comprehensive loss incorrectly included preferred dividends of $2.9 million and $2.3 million, respectively. Comprehensive loss will be corrected by revising the amounts included in previously-issued statements of comprehensive loss the next time they are required to be filed for comparative purposes.

Total revenue from contracts with customers	$	8,713	$	6,807	$	17,800	$	11,001

The revenue from products manufactured and sold by our Seamap and Klein businesses, is generally recognized at a point in time, or when the customer takes possession of the product, based on the terms and conditions stipulated in our contracts with customers. However, from time to time our Seamap and Klein businesses provide repair and maintenance services, or perform upgrades, on customer owned equipment in which case revenue is recognized over time. In addition, our Seamap business provides annual Software Maintenance Agreements (“SMA”) to customers who have an active license for software embedded in Seamap products. The revenue from SMA is recognized over time, with the total value of the SMA recognized in equal monthly amounts over the life of the contract.

The following table presents revenue from contracts with customers disaggregated by geography, based on shipping location of our customers:

	*Three Months Ended July 31,*				*Six Months Ended July 31,*
	*2022*		*2021*		*2022*		*2021*
	(in thousands)
United States	$	2,333	$	219	$	4,586	$	578
Europe		4,082		3,520		8,694		6,102
Middle East & Africa		142		675		180		689
Asia-Pacific		2,042		2,188		4,226		2,893
Canada & Latin America		114		205		114		739
Total revenue from contracts with customers	$	8,713	$	6,807	$	17,800	$	11,001

As of July 31, 2022, and January 31, 2022, contract assets and liabilities consisted of the following:

	*July 31, 2022*		*January 31, 2022*
Contract Assets:	(in thousands)
Unbilled revenue - current	$	43	$	28
Total unbilled revenue	$	43	$	28
Contract Liabilities:
Deferred revenue & customer deposits - current	$	2,665	$	2,569
Total deferred revenue & customer deposits	$	2,665	$	2,569

Considering the products manufactured and sold by our Seamap and Klein businesses and the Company’s standard contract terms and conditions, we expect our contract assets and liabilities to turn over, on average, within a period of three to nine months.

With respect to the disclosures above, sales and transaction-based taxes are excluded from revenue, and we do not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Also, we expense costs incurred to obtain contracts because the amortization period would be one year or less. These costs are recorded in selling, general and administrative expenses.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Notes to Financial Statements

Long-Term Debt [Text Block]

9. Notes Payable

On May 5, 2020, the Company, and its wholly owned subsidiary, Klein (collectively, the “Borrowers”), were granted loans (the “Loans”) from Bank of America, N.A. in the aggregate amount of approximately $1.6 million, pursuant to the Small Business Association's Paycheck Protection Program (the “PPP”), a component of the Coronavirus Aid, Relief, and Economic Security Act which was enacted on March 27, 2020.

The Loans, in the form of promissory notes (the “Notes”) dated May 1, 2020 issued by the Borrowers, were set to mature on May 1, 2022 and bore interest at a rate of 1% per annum, payable monthly commencing on November 1, 2020. The Notes stipulated various restrictions customary with this type of transaction including representations, warranties, and covenants, in addition to events of default, breaches of representation and warranties or other provisions of the Notes. In the event of default, the Borrowers would have become obligated to repay all amounts outstanding under the Notes. The Borrowers were permitted to prepay the Notes at any time prior to maturity with no prepayment penalties.

Under the terms of the PPP, funds from the Loans could only be used for payroll costs, rent, utilities and interest on other debt obligations incurred prior to February 15, 2020. In addition, certain amounts of the Loans could be forgiven if the funds were used to pay qualifying expenses.

In January 2021, the Loan granted to the Company in the amount of approximately $757,000 was forgiven resulting in other income of that amount. In February 2021, the Loan granted to Klein in the amount of approximately $850,000 was also forgiven, resulting in other income of that amount. As of July 31, 2022, the Company had no outstanding balance under the Loans.

Income Tax Disclosure [Text Block]

10. Income Taxes

For the six months ended July 31, 2022, the income tax expense from continuing operations was approximately $ 342,000 on a pre-tax loss from continuing operations of $4.2 million. For the six months ended July 31, 2021, the income tax expense from continuing operations was approximately $ 52,000 on a pre-tax loss from continuing operations of $6.4 million. The variance between our actual provision and the expected provision based on the U.S. statutory rate is due primarily to recording valuation allowances against the increase in our deferred tax assets in the respective periods, permanent differences between book income and taxable income, and the effect of foreign withholding taxes.

The Company files U.S. federal and state 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 Internal Revenue Service for fiscal years ended January 31, 2019 through 2022. The Company’s tax returns may also be subject to examination by state and local tax authorities for fiscal years ended January 31, 2017 through 2022. In addition, the Company's tax returns filed in foreign jurisdictions are generally subject to examination for the fiscal years ended January 31, 2017 through 2022.

The Company has determined that the undistributed earnings of foreign subsidiaries are not deemed to be indefinitely reinvested outside of the United States as of July 31, 2022. Furthermore, the Company has concluded that any deferred taxes with respect to the undistributed foreign earnings would be immaterial. Therefore, the Company has not recorded a deferred tax liability associated with the undistributed foreign earnings as of July 31, 2022.

For the six months ended July 31, 2022 and 2021, the Company did not recognize any tax expense or benefit related to uncertain tax positions.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Note 11 - Earnings Per Share

Notes to Financial Statements

Earnings Per Share [Text Block]

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 assumed vesting of unvested shares of restricted stock.

The following table presents the calculation of basic and diluted weighted average common shares used in the earnings per share calculation:

	*Three Months Ended July 31,*				*Six Months Ended July 31,*
	*2022*		*2021*		*2022*		*2021*
	(in thousands)				(in thousands)
Basic weighted average common shares outstanding		13,782		13,774		13,779		13,767
Stock options		—		79		—		58
Unvested restricted stock		5		29		5		18
Total weighted average common share equivalents		5		108		5		76
Diluted weighted average common shares outstanding		13,787		13,882		13,784		13,843

For the three and six months ended July 31, 2022 and 2021, 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.

12. Related Party Transaction

In September 2020 we entered into an equity distribution agreement (the “Equity Distribution Agreement”) with Ladenburg Thalmann & Co. Inc. (the “Agent”). The Co-Chief Executive Officer and Co-President of the Agent is the Non-Executive Chairman of our Board. Pursuant to the Equity Distribution Agreement, the Company may sell up to 500,000 shares of 9.00% Series A Cumulative Preferred Stock, par value $1.00 per share (the “Preferred Stock”) and 5,000,000 shares of $0.01 par value common stock (“Common Stock”) through an at-the-market offering program (the “ATM Offering Program”) administered by the Agent. Under the Equity Distribution Agreement, the Agent is entitled to compensation of up to 2.0% of the gross proceeds from the sale of Preferred Stock and Common Stock under the ATM Offering Program.

On November 12, 2021, the Company issued 432,000 shares of the Series A Preferred Stock, pursuant to an underwriting agreement, dated November 9, 2021, by and between the Company and Ladenburg Thalmann & Co. Inc. The Co-Chief Executive Officer and Co-President of Ladenburg Thalmann & Co. Inc is the Non-Executive Chairman of the Company’s board of directors. Net proceeds to the Company were approximately $9.5 million and the underwriter received underwriting discounts and commissions totaling approximately $576,000 in connection with this offering. The Non-Executive Chairman of the Company received no portion of these discounts and commissions.

During the three- and six-month periods ended July 31, 2022, the Company sold no shares of Preferred Stock under the ATM Offering Program. During the three- and six-month periods ended July 31, 2021, the Company sold 163,780 and 184,740 shares of Series A Preferred Stock under the ATM Offering Program, respectfully. Net proceeds from these sales for the three- and six-month periods ended July 31, 2021, were approximately $4.0 million and $4.5 million, respectively, and the Agent received compensation of approximately $82,000 and $92,000, respectively. The Non-Executive Chairman of the Board received no portion of this compensation.

During the three- and six-month periods ended July 31, 2022, the Company sold no shares of Common Stock under the ATM Offering Program. During the three- and six-month periods ended July 31, 2021, the Company sold 362 and 18,415 shares of Common Stock under the ATM Offering Program, respectfully. Net proceeds from these sales for the three- and six-month periods ended July 31, 2021, were approximately $1,000 and $43,000. Compensation to the Agent during this period was approximately $1,000, none of which received by the Non-Executive Chairman of the Board.

Shareholders' Equity and Share-Based Payments [Text Block]

13. Equity and Stock-Based Compensation

As of July 31, 2022, there are approximately 1,683,000 shares of Preferred Stock outstanding with an aggregate liquidation preference of approximately $42.0 million. Holders of our Preferred Stock are entitled to receive, when and as declared by the Board out of funds of the Company available for the payment of distributions, quarterly cumulative preferential cash dividends of $0.5625 per share of the $25.00 per share stated liquidation preference on our Preferred Stock. Dividends on the Preferred Stock are payable quarterly in arrears, on April 30, July 31, October 31, and January 31, of each year. During the three months ended July 31, 2022, the Board did not declare, and the Company did not pay a quarterly dividend on our Preferred Stock. As a result, the Company has approximately $947,000 of undeclared preferred dividends in arrears. During the six months ended July 31, 2022, the Board declared a quarterly dividend of $0.5625 per share on our Preferred Stock for the quarter ended April 30, 2022.

Total compensation expense recognized for stock-based awards granted under the Company’s equity incentive plan during the three- and six-month periods ended July 31, 2022 was approximately $ 152,000 and $ 388,000, respectively, and during the three- and six-month periods ended July 31, 2021, was approximately $ 115,000 and $ 224,000, respectively.
