The Company and Going Concern	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. This method can be used both onshore and offshore to remotely identify areas conducive to fluid entrapment to recommend areas with commercial hydrocarbon and/or geothermal potential. These audited consolidated financial statements for the year ended December 31, 2025 (the” 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 continues to be material uncertainties that cast 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. During 2024 the Company completed an SFD^® survey and had received deposits on three other SFD^® surveys planned to be executed in 2025 (the “2025 SFD^® Surveys”). As of the date of these financial statements, the Company has finished one of those SFD^® surveys and the interpretation phase of two of the 2025 SFD^® Surveys. In addition, during 2023 and 2024 the Company completed convertible debenture financings which resulted in raising additional net proceeds of approximately US$6,172,000 of which US$6,127,000 of the original proceeds have been converted to common shares as of December 31, 2025. The Company continues to develop its pipeline of opportunities to secure additional revenue contracts. The Company’s longer-term success remains dependent upon its ability to convert these revenue 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 certainty. Further financing options that may or may not be available to the Company include the issuance of new equity, debentures or bank credit facilities. The need for any of these options will be dependent on the timing of securing additional SFD^® related revenues and obtaining financing on terms that are acceptable to both the Company and the financier. 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. 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 2025, 2024 and 2023, 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, reaching the final milestone payment for the geothermal right, lease interest rates and terms, the fair value of convertible debentures, and the assumptions used to measure stock-based compensation expense.
