Consolidated Financial Statements

For the Years ended

December 31, 2023, 2022 and 2021

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of NXT Energy Solutions Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of NXT Energy Solutions Inc. (the Company) as at December 31, 2023, and the related consolidated statements of loss and comprehensive loss, shareholders' equity, and cash flows for the year ended December 31, 2023, and the related notes and schedules (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2023, and the results of its operations and its cash flows for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America ("US GAAP").

The consolidated financial statements of the Company as at December 31, 2022 and for the years ended December 31, 2022 and 2021, were audited by other auditors whose report dated March 31, 2023, expressed an unqualified opinion on those consolidated financial statements.

Material Uncertainty Related to Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company's current cash position is not expected to be sufficient to meet the Company's obligations and planned operations for a year beyond the date of auditor's report, unless additional financing is obtained or new revenue contracts are completed. This raises substantial doubt about the Company's ability to continue as a going concern. Management's plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue recognition

Critical Audit Matter Description

The Company recognized revenue of $2,145,716 for the year ended December 31, 2023. As described in Notes 2 and 21 to the consolidated financial statements, the performance obligation for NXT in SFD® surveys is the acquisition, processing, interpretation and integration of Stress Field Detection (SFD®) data. Revenue from the sale of SFD® survey contracts is recognized over time by measuring the progress toward satisfaction of its performance obligation to the customer. The Company uses direct survey costs as the input measure to recognize revenue in any fiscal period. The percentage of direct survey costs incurred to date over the total expected survey costs to be incurred, provides an appropriate measure of the stage of the performance obligation being satisfied over time.

The accounting for contracts that are not complete at the reporting date involves significant judgment, particularly as it relates to determining the total anticipated costs at completion.

Audit Response

We responded to this matter by performing procedures in relation to revenue recognition. Our audit work in relation to this included, but was not restricted to, the following:

·

Agreeing key contractual terms to the executed service agreement signed in the year ended December 31, 2023.

·

Agreeing total revenue per the agreement to the issued invoices and other supporting documentation and reconciling it to the revenue recognized during the reporting period.

·

Inquiring of management and operational personnel to understand the status of the project and relevant activities.

·

Evaluating the reasonableness of management's calculation of the total anticipated costs at completion, including testing of significant inputs, such as estimated labour costs, material costs, subcontractor costs, and other costs, to appropriate supporting documentation.

·

Testing the costs incurred to date as at the end of the reporting period, including costs accrued as at December 31, 2023, by testing cut-off and inspecting supporting documents for a sample of transactions.

·

Recalculating revenue recognized during the year ended December 31, 2023, based on the total anticipated costs at completion and costs incurred to date as at the end of the reporting period.

Going Concern

Critical Audit Matter Description

As described in Note 1 to the consolidated financial statements, the Company's current cash position is not expected to be sufficient to meet the Company's obligations and planned operations for a year beyond the date that these consolidated financial statements have been issued, unless additional financing is obtained or new revenue contracts are completed.

We identified the assessment of the ability of the Company to continue as a going concern as a critical audit matter due to the significant assumptions and judgements made by management in estimating future cash flows, which are subject to high degree of uncertainty.

This matter is also described in the "Material Uncertainty Related to Going Concern" section of our report.

Audit Response

We responded to this matter by performing procedures in relation to the assessment of the ability of the Company to continue as a going concern. Our audit work in relation to this included, but was not restricted to, the following:

·

Obtaining an understanding from management on the Company's future plans for the operations, including financing arrangements.

·

Evaluating the key assumptions used in management's model to estimate future cash flows by comparing assumptions used by management against historical performance, budgets, economic and industry indicators and publicly available information.

·

Comparing the assumptions related to revenue projections to those used in assessments of impairment indicators for non-financial assets.

·

Assessing the adequacy of the going concern disclosure included in Note 1 to the consolidated financial statements and considering whether these appropriately reflected the assessments that management performed.

Notes to the Consolidated Financial Statements

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

1. The Company and going concern

NXT Energy Solutions Inc. (the "Company" or "NXT") is a publicly traded company based in Calgary, Alberta Canada and listed on the Toronto Stock Exchange ("TSX").

NXT's proprietary Stress Field Detection ("SFD®") technology is an airborne survey system that utilizes the principles of quantum mechanics to infer stress anomalies of exploration interest. The method can be used both onshore and offshore to remotely identify areas conducive to fluid entrapment in order to recommend areas with commercial hydrocarbon and/or geothermal potential.

These consolidated financial statements of NXT have been prepared by management in accordance with generally accepted accounting principles of the United States of America ("US GAAP").

These consolidated financial statements reflect adjustments, all of which are normal recurring adjustments that are, in the opinion of management, necessary to reflect fairly the financial position and results of operations for the respective periods.

These consolidated financial statements have been prepared on a going concern basis. The going concern basis of presentation assumes that NXT will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

The events described in the following paragraphs highlight that there is substantial doubt about NXT's ability to continue as a going concern within one year after the date that these consolidated financial statements have been issued. The Company's current cash position is not expected to be sufficient to meet the Company's obligations and planned operations for a year beyond the date that these consolidated financial statements have been issued.

Since 2022, the Company has deferred payment of certain operating costs, including payroll and other general and administrative costs. During 2023 and subsequent to December 31, 2023, the Company completed private placements which resulted in raising an additional net proceeds of $5,079,612 (Notes 10 and 15) and completed a SFD® survey which generated operating funds. Further financing options that may or may not be available to the Company include issuance of new equity, debentures or bank credit facilities. The need for any of these options will be dependent on the timing of securing new SFD® related revenues and obtaining financing on terms that are acceptable to both the Company and the financier.

NXT continues to develop its pipeline of opportunities to secure new revenue contracts. However, the Company's longer-term success remains dependent upon its ability to convert these opportunities into successful contracts, to continue to attract new client projects, expand its revenue base to a level sufficient to exceed fixed operating costs, and generate consistent positive cash flow from operations. The occurrence and timing of these events cannot be predicted with sufficient certainty.

The consolidated financial statements do not reflect adjustments that would be necessary if the going concern basis was not appropriate. If the going concern basis was not appropriate for these consolidated financial statements, then adjustments would be necessary in the carrying value of the assets and liabilities, the reported revenues and expenses, and the balance sheet classifications used. These adjustments could be material.

Notes to the Consolidated Financial Statements

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

Use of Estimates and Judgements

In preparing these consolidated financial statements, NXT is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities, revenues and expenses since the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgment in making these estimates and assumptions. In the opinion of management, these consolidated financial statements have been properly prepared within reasonable limits of materiality and within the framework of the Company's significant accounting policies. The estimates and assumptions used are based upon management's best estimate as at the date of the consolidated financial statements. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the period when determined. Actual results may differ from those estimates.

Certain estimates and judgments have a material impact where the assumptions underlying these accounting estimates relate to matters that are highly uncertain at the time the estimate or judgment is made or are subjective. In 2023 and 2022, the estimates and judgments included the assessment of impairment indicators of intellectual property and recognition of SFD® related revenue.

The Company reviews intellectual property for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. The Company considers both internal and external factors when assessing for potential indicators of impairment of its intellectual property, including the consideration of historical and forecasted SFD® related revenues, market capitalization, control premiums, and the SFD® related revenue multiples compared to industry peers. When indicators of impairment exist, the Company first compares the total of the estimated undiscounted future cash flows or the estimated sale price to the carrying value of an asset. If the carrying value exceeds these amounts, an impairment loss is recognized for the excess of the carrying value over the estimated fair value of the intellectual property.

Other accounting estimates and judgments that may have a material impact on the financial statements include: the forward looking assumptions related to the going concern assumption, the estimated useful lives of intellectual property and property, plant and equipment, lease interest rates and terms, and the assumptions used to measure stock based compensation expense.

2. Significant Accounting Policies

Basis of Presentation

These consolidated financial statements for the year ended December 31, 2023 have been prepared by management in accordance with generally accepted accounting principles of the United States of America ("US GAAP").

Notes to the Consolidated Financial Statements

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

Consolidation

These consolidated financial statements reflect the accounts of the Company and its wholly owned subsidiaries (all of which are inactive). All significant inter-company balances and transactions among NXT and its subsidiaries have been eliminated and are therefore not reflected in these consolidated financial statements.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and short term Guaranteed Investment Certificates ("GIC's") with an original maturity less than 90 days from the date of acquisition.

Short Term Investments

Short term investments consist of short term GICs, with original maturity dates greater than 90 days and up to one year.

Derivative Instruments

As at December 31, 2023 and 2022, NXT had no outstanding derivative instruments.

Fair Value Measures

For any balance sheet items recorded at fair value on a recurring basis or non-recurring basis, the Company is required to classify the fair value measure into one of three categories based on the fair value hierarchy noted below.

In Level I, the fair value of assets and liabilities is determined by reference to quoted prices in active markets for identical assets and liabilities that the Company has the ability to assess at the measurement date.

At December 31, 2023 the fair value of the share based payment "Compensation Expense" was based on share price using Level I inputs. At December 31, 2022, the fair value of the restricted stock units ("RSU") liability based on share price was determined using Level I inputs.

In Level II, determination of the fair value of assets and liabilities is based on the extrapolation of inputs, other than quoted prices included within Level I, for which all significant inputs are observable directly or indirectly. Such inputs include published exchange rates, interest rates, yield curves and stock quotes from external data service providers. Transfers between Level I and Level II would occur when there is a change in market circumstances. There are no Level II fair value measures.

In Level III, the fair value of assets and liabilities measured on a recurring basis is determined using a market approach based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities measured at fair value can fluctuate between Level II and Level III depending on the proportion of the value of the contract that extends beyond the time frame for which inputs are considered to be observable. As contracts near maturity and observable market data becomes available, the contracts are transferred out of Level III and into Level II.

Notes to the Consolidated Financial Statements

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

The determination of the fair value of the acquisition of the Intellectual property (Note 8) was determined using Level III inputs in 2021.

Measurement of credit losses on financial instruments

The impairment model of financial instruments is based on expected losses rather than incurred losses. In making the assessment of expected losses, the Company considers the following factors: historically realized bad debts; a counterparty's present financial condition and whether a counterparty has breached certain contracts; the probability that a counterparty will enter bankruptcy; changes in economic conditions that correlate to increased levels of default and term to maturity of the specific receivable. These expected credit losses are recognized as an allowance rather than as a direct write-down of the amortized cost basis.

Deposits

Deposits consist of security payments made to lessors for the Company's office and aircraft lease. They are classified as long term if the lease end date is greater than one year.

Property and Equipment

Property and equipment is recorded at cost, less accumulated amortization, which is recorded over the estimated service lives of the assets using the following annual rates and methods:

Survey equipment

20% declining balance

Aircraft equipment

10% declining balance

Computers

30% declining balance

Furniture and other equipment

20% declining balance

Leasehold improvements

10% declining balance

Intellectual Property

Intellectual property acquired is recorded at cost, less accumulated amortization, which is recorded over the estimated minimum useful life of the assets. The Company incurs periodic costs that are expensed when incurred to file patents and to maintain them.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, which includes property, equipment and intellectual property for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. The Company considers both internal and external factors when assessing for potential indicators of impairment, and with respect to intellectual property, the Company's assessment includes consideration of historical and forecasted SFD® related revenues, market capitalization, control premiums, and the SFD® related revenue multiples compared to industry peers.

Notes to the Consolidated Financial Statements

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

When indicators of impairment exist, the Company first compares the total of the estimated undiscounted future cash flows or the estimated sale price to the carrying value of an asset. If the carrying value exceeds these amounts, an impairment loss is recognized for the excess of the carrying value over the estimated fair value of the asset.

Convertible Debentures

Convertible debentures are recorded as a current liability if the Company has an obligation to deliver cash to the holder on demand on or before the maturity date and a long-term liability if non-demand and the maturity date is greater than one year. If the convertible debentures are converted to either voting preferred or common shares, the preferred or common shares will be classified as equity. Interest on the convertible debenture is accrued as earned. Dividends on preferred shares will only be accrued on dividends declared by the Board of Directors of the Company.

Research and Development Expenditure

Research and development ("R&D") expenditures incurred to develop, improve and test the SFD® survey system and related components are expensed as incurred. Any intellectual property that is acquired for the purpose of enhancing research and development projects, if there is no alternative use for the intellectual property, is expensed in the period acquired. No significant external R&D was incurred in the years ended 2023, 2022 and 2021.

Foreign Currency Translation

The Company's functional currency is the Canadian dollar. Revenues and expenses denominated in foreign currencies are translated into Canadian dollars at the average exchange rate for the applicable period. Monetary assets and liabilities are translated into Canadian dollars at the exchange rate in effect at the end of the applicable period. Non-monetary assets and liabilities are recorded at the relevant exchange rates for the period in which the balances arose. Any related foreign exchange gains and losses resulting from these translations are included in the determination of net income (loss) for the period.

Income Taxes

NXT follows the asset and liability method of accounting for income taxes. This method recognizes deferred income tax assets and liabilities based on temporary differences in reported amounts for financial statement and income tax purposes, at the income tax rates expected to apply in the future periods when the temporary differences are expected to be reversed or realized. The effect of a change in income tax rates on deferred income tax assets and deferred income tax liabilities is recognized in income in the period when the tax rate change is enacted. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized.

Stock Based Compensation

NXT follows the fair value method of accounting for stock options, restricted stock units, deferred stock units, and the employee share purchase plan (the "Share Compensation Plans") that are granted to acquire common shares under NXT's Share Compensation Plans. For equity-settled stock-based compensation awards, fair values are determined at the grant date and the expense, net of estimated forfeitures, is recognized over the requisite service period with a corresponding increase recorded in contributed capital. An adjustment is made to compensation for any differences between the estimated forfeitures and the actual forfeitures. For cash-settled stock-based compensation awards, fair values, based on observable prices, are determined at each reporting date and periodic changes are recognized as compensation costs, with a corresponding change to liabilities. Stock-based awards with performance conditions are recognized as compensation costs only when the performance condition is probable of being met.

Upon exercise or realization of the equity-settled Share Compensation Plans, the consideration received by NXT, and the related amount which previously recorded in contributed capital, is recognized as an increase in the recorded value of the common shares of the Company.

Net Income (Loss) Per Share

Basic income (loss) per share amounts are calculated by dividing net income (loss) by the weighted average number of common shares that are outstanding for the fiscal period. Shares issued during the period are weighted for the portion of the period that the shares were outstanding. Diluted income per share, in periods when NXT has net income, is computed using the treasury stock method, whereby the weighted average number of shares outstanding is increased to include any additional shares that would be issued from the assumed exercise of stock options and restricted stock units. The incremental number of shares added under the treasury stock method assumes that outstanding stock options and restricted stock units that are exercisable at exercise prices below the Company's average market price (i.e. they were "in-the-money") for the applicable fiscal period are exercised and then that number of incremental shares is reduced by the number of shares that could have been repurchased by the Company from the issuance proceeds, using the average market price of the Company's shares for the applicable fiscal period.

No addition to the basic number of shares is made when calculating the diluted number of shares if the diluted per share amounts become anti-dilutive (such as occurs in the case where there is a net loss for the period).

Revenue

SFD® Surveys

The performance obligation for NXT in SFD® surveys is the acquisition, processing, interpretation and integration of Stress Field Detection (SFD®) data. Revenue from the sale of SFD® survey contracts (excluding any related foreign value added taxes) is recognized over time by measuring the progress toward satisfaction of its performance obligation to the customer. All funds received or invoiced in advance of recognition of revenue are reflected as contract obligations and classified as a current liability on our balance sheet.

Notes to the Consolidated Financial Statements

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

The Company uses direct survey costs as the input measure to recognize revenue in any fiscal period. The percentage of direct survey costs incurred to date over the total expected survey costs to be incurred, provides an appropriate measure of the stage of the performance obligation being satisfied over time.

SFD®Data Sales

The performance obligation for NXT in SFD® data sales is the delivery of the promised specific services as itemized in the contract with the customer. Revenue from the sale of SFD® data (excluding any related foreign value added taxes) is recognized once the services are completed and the data is transferred to the customer.

Leases

The Company determines if an arrangement is an operating or finance lease, as defined under U.S. GAAP, at inception. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. These leases are included in right-of-use ("ROU") assets and lease obligations in the Consolidated Balance Sheet.

ROU assets represent the Company's right to use an underlying asset for the lease term and lease obligations represent the obligation to make lease payments arising from such leases. Lease obligations are recognized at the lease commencement date based on the present value of remaining lease payments over the lease term, taking into consideration conditions such as incentives and termination penalties, as appropriate. A corresponding ROU asset is recognized at the amount of the lease obligation, adjusted for payments made prior to lease commencement or initial direct costs, if any.

When calculating the present value, the Company uses the rate implicit in the lease, or uses its incremental borrowing rate for a similar term and risk profile based on the information available at the commencement date. The Company's lease terms may have options to extend or terminate the lease which are included in the calculation of lease obligations when it is reasonably certain that it will exercise those options. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Office and equipment lease expenses are included within General and administrative expenses; the aircraft lease cost is included within SFD® related costs.

Lease agreements can contain both lease and non-lease components, which are accounted for separately.

Government grants

Government grants are recognized when there is reasonable assurance that the grant will be received, and all attached conditions will be complied with. When the grant relates to an expense item, it is recognized as an expense reduction in the period in which the costs are incurred. Where the grant relates to an asset, it is recognized as a reduction to the net book value of the related asset and then subsequently in net loss over the expected useful life of the related asset through lower charges to amortization and impairment.

SFD®Geothermal Right

The Company acquired the SFD® technology rights for geothermal resources ("Geothermal Right") from the CEO on April 18, 2021. The consideration deliverable by the Company in connection with the acquisition of the Geothermal Right is set forth below:

1.

US$40,000 (CDN$50,310) signature payment, which became due immediately and was paid on April 22, 2021;

2.

300,000 common shares, which were issued in December 2021;

3.

CDN$15,000 signature milestone payment paid in August 2021;

4.

US$200,000 milestone payment which will become due in the event that the Company's cash balance exceeds CDN$5,000,000 due to receipt of specifically defined funds from operations; and

5.

US$250,000 milestone payment would have become due in the event that the Company executed and completed and received full payment for an SFD® contract valued at US$10,000,000 or greater, provided such contract was entered into and completed and payment of at least US$5,000,000 was received by April 18, 2023. This milestone expired as of April 18, 2023.

As of December 31, 2023, the Company has recognized $275,610 for the acquisition Geothermal Right which is the combination of the US$40,000 (CDN$50,310) and CDN$15,000 signature payments, the value of the 300,000 common shares of $207,300 and other costs of $3,000. The cost of the remaining milestone will be recognized when it is deemed probable that the milestone will be achieved by a special committee of the Board of Directors, comprised entirely of independent directors. The Board of Directors delegated authority to the special committee to determine when the milestones have been achieved. As of December 31, 2023 the remaining milestone is still deemed not probable of being achieved.

The current book value of the Geothermal Right is being amortized on a straight line basis over its estimated useful life of 20 years. The annual amortization expense expected to be recognized is approximately $13,781 per year for a 5 year aggregate total of approximately $68,902.

19. Financial instruments

Non-derivative financial instruments:

The Company's non-derivative financial instruments consist of cash and cash equivalents, accounts receivable, deposits, accounts payables and accrued liabilities, long-term debt and convertible debentures. The carrying value of these financial instruments, excluding lease obligations and long-term debt, approximates their fair values due to their short terms to maturity.

Credit Risk

Credit risk arises from the potential that the Company may incur a loss if counterparty to a financial instrument fails to meet its obligation in accordance with agreed terms. The Company's financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The carrying value of cash and cash equivalents and accounts receivable reflects management's assessment of maximum exposure to credit risk. At December 31, 2023, cash and cash equivalents included balances in bank accounts placed with financial institutions with investment grade credit ratings and Accounts Receivable. The Company manages Accounts Receivable credit risk by requiring advance payments before entering into certain contract milestones and when possible, accounts receivable insurance.

As at and for the years ended December 31, 2023, 2022 and 2021

(Expressed in Canadian dollars unless otherwise stated)

Foreign Exchange Risk

The Company is exposed to foreign exchange risk in relation to its holding of significant US$ balances in cash and cash equivalents, deposits, accounts payables, accrued liabilities, and lease obligations, and entering into United States dollar revenue contracts. The Company does not currently enter into hedging contracts, but to mitigate exposure to fluctuations in foreign exchange the Company uses strategies to reduce the volatility of United States Dollar assets including converting excess United States dollars to Canadian dollars. As at December 31, 2023, the Company held net U.S. dollar liabilities totaling US$1,179,649. Accordingly, a hypothetical 10% change in the value of one United States dollar expressed in Canadian dollars as at December 31, 2023 would have had an approximately $156,063 effect on the unrealized foreign exchange gain or loss for the year.

21. Geographic information

The Company generates revenue from its SFD® survey system that enables the clients to focus their exploration decisions concerning land commitments, data acquisition expenditures and prospect prioritization on areas with the greatest potential. NXT conducts all of its survey operations from its head office in Canada, and occasionally maintains administrative offices in foreign locations if and when needed. Revenue fluctuations are a normal part of SFD® survey system sales and can vary significantly year-over-year.

Revenues for the years ended December 31, 2023 and 2021 were generated solely from the Hydrocarbon Right and only one customer in each year, but not the same customer between years. There were no revenues attributable to the Geothermal Right since its acquisition in 2021.
