Notes to Condensed Consolidated Financial Statements (Unaudited)
1.** **Organization and Description of Business
Terrestrial Energy Inc. (the “Company” or “TEI”), a Company incorporated under the laws of the State of Delaware, is a Company developing Generation IV nuclear technology, as defined by the Generation IV International Forum. The Company is committed to delivering reliable, resilient, emission-free, and cost-competitive energy by developing and deploying its patented Integral Molten Salt Reactor (“IMSR”) for commercial operation.
On October 28, 2025 (the“Closing Date”), Terrestrial Energy Inc. (formerly HCM II Acquisition Corp.“HCM II”) consummated the transactions set forth by the Business Combination Agreement dated March 26, 2025 with Terrestrial Energy Development Inc. (formerly Terrestrial Energy, Inc.) (“TEDI”) and HCM II Merger Sub Inc. (the“Business Combination”). Upon closing, Merger Sub merged with and into TEDI, with TEDI surviving as a wholly owned subsidiary of Terrestrial Energy Inc. (collectively, the“Transactions”). Under the terms of the Agreement, TEDI’s outstanding shares of common stock and convertible notes were exchanged for shares in Terrestrial Energy Inc. at an exchange ratio specified in the Business Combination Agreement (the“Recapitalization”).
The Business Combination was accounted for as a reverse recapitalization in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). Under this method of accounting, TEDI was deemed to be the accounting acquirer for financial reporting purposes.
The Business Combination closed on Tuesday, October 28, 2025, with trading commencing on the Nasdaq Stock Market LLC (“Nasdaq”) on Wednesday, October 29, 2025.
Upon closing of the transaction, the combined company became known as Terrestrial Energy Inc. and its securities and warrants were listed on Nasdaq under the symbols“IMSR” and“IMSRW”, respectively.
Liquidity and Going Concern
Historically, the Company’s primary sources of liquidity have been cash flows from private fundraising offerings to related parties or other investors and other financing activities to fund operations. For the six months ended June 30, 2026 and 2025, the Company reported operating losses of $23,603 and $10,048, respectively, and negative cash flows from operations of $14,794 and $6,885, respectively. As of June 30, 2026, the Company had $130,737 in cash and cash equivalents and $142,781 in short-term investments. The Company had net working capital of $268,621 and an accumulated deficit of $144,527.
The Company believes that it has sufficient liquidity to support operations for at least the next twelve months following the date of issuance of the condensed consolidated financial statements. This projection is based on the Company’s current expectations regarding cost structure, cash burn rate and other operating assumptions.
2.** **Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
The accompanying unaudited condensed consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Articles 8 and 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, it does not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. The information herein should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed on March 30, 2026. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair statement of the financial position, operating results, and cash flows for the periods presented.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions. The Company believes that the estimates, judgments and assumptions made when accounting for items and matters such as, but not limited to, determination of deferred income for government assistance, useful life of property and equipment and intangible assets, fair value of stock options granted, recognition of deferred income tax assets, determination of incremental borrowing rate used to measure lease liabilities, and warrants, are reasonable based on information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the condensed consolidated financial statements, as well as amounts reported on the statements of operations during the periods presented. Actual results could differ from those estimates.
Foreign Currency
The Company’s reporting currency is the United States dollar (“USD”). The functional currency of each subsidiary is determined by the currency of the primary economic environment in which the entity operates. The functional currency of Terrestrial Energy Ontario Inc. (“TEON”) is the Canadian dollar (“CAD”), that of Terrestrial Energy Limited, a company incorporated under the laws of England and Wales, the Pound Sterling and that of Terrestrial Energy USA, Inc., the USD. Assets and liabilities of the operating subsidiaries are translated at the spot rate in effect at the applicable reporting date. Revenues and expenses of the operating subsidiaries are translated at the average exchange rates in effect during the applicable period. The resulting foreign currency translation adjustment is recorded as Accumulated other comprehensive income**(**loss), which is reflected as a separate component of Stockholders’ Equity (Deficit). The functional currency is translated into U.S. dollars for balance sheet accounts using currency exchange rates in effect as of the balance sheet date, and for revenue and expense accounts using a weighted-average exchange rate during the respective reporting period. The transactions in foreign currency (that is a different currency than the functional currency of the entity) are converted at the exchange rate prevailing to the date of the transaction. The assets and liabilities denominated in foreign currencies are evaluated in the current period on the date of the closing or at the opening rate, when applicable. The translation adjustments are deferred as a separate component of stockholders’ equity in “Accumulated other comprehensive income (loss)”. Gains or losses resulting from transactions denominated in foreign currencies and intercompany debt that is not of a long-term investment nature are included in foreign exchange gain (loss) in the condensed consolidated statements of operations and comprehensive loss.
Concentration of Credit Risks
The Company’s cash accounts in a financial institution may at times exceed the Federal Depository Insurance Corporation coverage of $250,000. No losses have been incurred to date on any deposit balance.
Fair Value Measurements
Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels:
| ● | Level 1: Inputs are quoted prices in active markets for identical assets or liabilities. |
| ● | Level 2: Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. |
| ● | Level 3: Inputs are unobservable for the asset or liability. |
The carrying amounts of certain financial instruments, such as cash equivalents, prepaid expenses and other current assets, accounts payable and accrued expenses, approximate fair value due to their relatively short maturities. The Company’s investments are classified as Level 1 or Level 2 assets (as described in Note 3). The valuation techniques used to measure the fair values of the Company’s Level 2 financial instruments, which generally have counterparties with high credit ratings, are based on quoted market prices or model-driven valuations using significant inputs derived from and corroborated by observable market data.
Warrants
The Company reviews the terms of warrants to purchase its common stock to determine whether warrants should be classified as liabilities or stockholders’ equity (deficit) in its condensed consolidated balance sheets. In order for a warrant to be classified in stockholders’ equity (deficit), the warrant must be (i) indexed to the Company’s equity and (ii) meet the conditions for equity classification.
If a warrant does not meet the conditions for stockholders’ equity (deficit) classification, it is carried on the condensed consolidated balance sheets as a warrant liability measured at fair value, with subsequent changes in the fair value of the warrant recorded in other income (expense) in the condensed consolidated statements of operations and comprehensive loss. If a warrant meets both conditions for equity classification, the warrant is initially recorded, at its relative fair value on the date of issuance, in stockholders’ equity (deficit) in the condensed consolidated balance sheets, and the amount initially recorded is not subsequently remeasured at fair value.
Stock-Based Compensation
The Company accounts for stock-based compensation arrangements granted to employees in accordance with Accounting Standards Codification (“ASC”) 718, “Compensation: Stock Compensation”, by measuring the grant date fair value of the award and recognizing the resulting expense over the period during which the employee is required to perform service in
exchange for the award. Equity-based compensation expense is only recognized for awards subject to performance conditions if it is probable that the performance condition will be achieved. The Company accounts for forfeitures when they occur.
The Company uses the Black-Scholes option pricing model to determine the grant date fair value of its stock-based compensation. This model requires the Company to estimate the expected volatility and the expected term of the stock options, which are highly complex and subjective variables. The Company uses an expected volatility of its stock price during the expected life of the options that is based on the historical performance of the Company’s stock price as well as including an estimate using similar companies. The expected term is computed using the simplified method as the Company’s best estimate given its lack of actual exercise history. The Company has selected a risk-free rate based on the implied yield available on U.S. Treasury securities with a maturity equivalent to the expected exercise term of the stock option.
Prior to the Closing of the Business Combination, there was no public market for the Company’s common stock. Therefore, the Company determined the fair value of common stock at the time of each grant of stock options by considering a number of objective and subjective factors in accordance with applicable elements of the practice aid issued by the American Institute of Certified Public Accountants titled, “Valuation of Privately Held Company Equity Securities Issued as Compensation.” Stock options granted by the Company have exercise prices equal to the fair value of the Company’s common stock, as determined by the Company on the date of grant. After the Closing of the Business Combination, the closing price of the common stock on Nasdaq is used as the fair value of the Company’s common stock.
The Company grants restricted stock units (“RSUs”) to employees and non-employee directors as part of its equity-based compensation program. RSUs represent the right to receive shares of the Company’s common stock upon vesting, subject to specified service. RSUs do not have voting or dividend rights prior to the issuance of shares, except for dividend equivalents if and when declared, as applicable under the terms of the award agreements.
The Company accounts for RSUs in accordance with ASC 718, Compensation—Stock Compensation. Compensation expense for RSUs is measured at the grant-date fair value, which is equal to the closing market price of the Company’s common stock on the date of grant. For RSUs subject solely to service-based vesting conditions, compensation expense is recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the award. The Company accounts for forfeitures as they occur.
Upon vesting, each RSU is converted into one share of the Company’s common stock. The Company may withhold shares to satisfy statutory tax withholding requirements. The issuance of shares upon vesting results in an increase to common stock and additional paid-in capital.
Government Grants
Government grants are recognized where 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, the grant is recognized in other income as government grants deferred over the period necessary to match the grant on a systematic basis to the costs that it is intended to compensate. Where the grant relates to an asset, it is recognized as deferred income, and then recognized as income over the useful life of the related depreciable asset.
Net Loss Per Share
Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The two-class method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income (loss) available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to shares in undistributed
earnings as if all income (loss) for the period had been distributed. The Company’s preferred stock does not contractually require the holders of such stock to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss attributable to common stockholders, such losses are not allocated to such participating securities.
Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common stock outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. For purposes of this calculation, stock options, warrants, and restricted stock units have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive for all periods presented.
Segment reporting
The Company has asingle operating and reportable segment. The Company’s Chief Executive Officer (“CEO”) is its Chief Operating Decision Maker (“CODM”), who reviews financial information presented on a consolidated basis for the purposes of making operating decisions, allocating resources and evaluating financial performance.
Emerging Growth Company Status
The Company is an emerging growth company, as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that the Company (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.
Recent Accounting Pronouncements
The Company has assessed the adoption impacts of recently issued accounting standards by the Financial Accounting Standards Board on the Company’s condensed consolidated financial statements as well as material updates to previous assessments, if any, to the Company’s annual audited consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2025.

- Leases
During the six months ended June 30, 2026, the Company entered into three lease arrangements with the Board of Regents of The Texas A&M University System related to its operations at the Texas A&M-RELLIS campus in Bryan, Texas.
In March 2026, the Company commenced an operating lease for approximately 1,775 square feet of office space. The lease has an initial term oftwo years and provides the Company with three additionalone-year renewal options. Annual base rent is approximately$116 and increases by 3.5% beginning on the second anniversary of the lease commencement date and annually thereafter.
On June 15, 2026, the Company entered intotwo ground lease arrangements with the Texas A&M University System covering an aggregate of approximately 77.7 acres at the Texas A&M-RELLIS campus. The first lease covers approximately 44.4 acres, expires on March 31, 2028, and provides for annual base rent of approximately$1,110, payable quarterly and subject to a 3.75% increase on the first anniversary of the commencement date. The second lease covers approximately 33.3 acres, has an initial term ending September 1, 2026, and may be extended through April 30, 2027. Annualized base rent under the second lease is approximately$0.8 million, payable quarterly and prorated for any partial period, before any approved sponsored-research credits. Because the term of the 33.3-acre lease, including the extension period, does not exceed 12 months, the Company elected the short-term lease recognition exemption and did not recognize a right-of-use asset or lease liability for that arrangement. Payments under the short-term lease are recognized as lease expense over the lease term.
In connection with operating leases commenced during the six months ended June 30, 2026, the Company recognized approximately $2,125 of operating lease right-of-use assets and corresponding lease liabilities. As of June 30, 2026 and December 31, 2025, operating lease right-of-use assets were approximately $3,595 and $1,814, respectively, and operating lease liabilities were approximately $3,809 and $1,984, respectively. As of June 30, 2026, operating lease liabilities included approximately $1,803 classified as current and $2,006 classified as noncurrent.
- Stockholders’ Equity (Deficit)
Preferred Stock
The Company has authorized 1,000,000 shares of preferred stock, par value $0.0001 per share. The Company’s board of Directors is authorized, without further stockholder action, to issue preferred stock in one or more series and to establish the designations, powers, preferences and rights of each such series and the qualifications, limitations and restrictions thereof. As of June 30, 2026 and December 31, 2025, no shares of Preferred Stock were issued and outstanding.
Common Stock
The Company’s Board of Directors has authorized 500,000,000 shares of common stock, par value $0.0001. As of June 30, 2026 and December 31, 2025, the Company had 82,718,567 and 81,771,422 shares of common stock issued and outstanding.
Common Stock Warrants
As of June 30, 2026 and December 31, 2025, the Company had 30,276,119 outstanding warrants to purchase common stock at a weighted average exercise price of $8.24 per share.
Call Options
Pursuant to various call option agreements entered into with certain stockholders prior to the Company’s Business Combination, the Company retains the right to repurchase up to an aggregate of 6,124,297 shares of its outstanding common stock at fixed exercise prices ranging from $1.12 CAD to $2.24 per share. These call options are exercisable at the Company’s discretion and expire at various dates ranging from December 31, 2035, through March 7, 2043. The call options are not subject to any service, performance, or market-based vesting conditions and are not transferable without Company consent. The Company has not exercised any of these call options to date.
The call options continue to be valid and enforceable following the consummation of the Business Combination. These instruments are presented within stockholders’ equity (deficit) at the original consideration price per share and are not remeasured unless exercised.
Exchangeable Shares
As of June 30, 2026 and December 31, 2025, the Company had 23,216,687 and 24,011,017 exchangeable shares outstanding. These shares are legally issued by Terrestrial Energy Canada (Exchange) Inc., a wholly-owned subsidiary of the Company (“ExchangeCo”). Each exchangeable share is convertible on a 1-for-1 basis into the Company’s common shares, either at the option of the holder or upon the occurrence of certain events. The exchangeable shares carry economic rights and dividend entitlements equivalent to the Company’s corresponding equity instruments and participate in Company-level voting through a special voting mechanism. Exchangeable shares hold limited economic rights with respect to ExchangeCo and are not entitled to dividends of ExchangeCo; provided that holders of exchangeable shares are entitled to dividends paid on Company shares.
The Company has entered into a support and exchange agreement with ExchangeCo and a trustee to guarantee all obligations associated with the exchangeable shares and ensure that holders receive equivalent rights that are intended to be substantively equivalent to direct shareholders of the Company. As such, these instruments are treated as equity of the Company and not reported as noncontrolling interests. During the three months ended June 30, 2026 and 2025,476,133 andzero exchangeable shares, respectively, were exchanged for common shares. During the six months ended June 30, 2026 and 2025,794,330 andzero exchangeable shares, respectively, were exchanged for common shares.
- Net Loss per Share of Common Share
Prior to the Business Combination, the Company used the two-class method required for participating securities. The two-class method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income (loss) available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to shares in undistributed earnings as if all income (loss) for the period had been distributed. The Company’s preferred stock that was outstanding prior to the Business Combination contractually entitled the holders of such stock to participate in dividends but did not contractually require the holders of such stock to participate in losses of the Company. Accordingly, in periods in which the Company reported a net loss attributable to common stockholders, such losses were not allocated to the preferred stock. The Company may be required to issue additional common shares pursuant to contingent value rights (“CVRs”) issued in connection with the Business Combination. The number of shares issuable is contingent upon the Company’s future stock price performance over a specified measurement period. As the contingency has not been met as of June 30, 2026, these shares have not been included in the calculation of basic or diluted net loss per share.
After the Business Combination, the Company applied the treasury stock method to determine the dilutive effect of potentially dilutive securities, and the if-converted method to determine the dilutive effect of any potentially dilutive convertible securities, as post-merger, the Company’s only participating securities were shares of the Company’s common stock, and any dividends declared on the common stock would be forfeitable if not vested.
Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common stock outstanding during the period, without consideration of potentially dilutive securities. There areno potentially dilutive securities included in the Company’s diluted net loss per share calculation for the six months ended June 30, 2026 and 2025, as the effect of any potentially dilutive security is anti-dilutive due to the net losses in those periods.
The table below sets forth the computation of basic and dilutive net loss per share:

| Net loss per share, basic and diluted | | $(0.09) | | $(0.10) | | $(0.19) | | $(0.20) |
The weighted-average shares outstanding above include both common shares and exchangeable shares outstanding at June 30, 2026 and 2025 as these shares are exchangeable on aone-for-one basis into the Company’s common shares and are therefore economically equivalent to common shares outstanding.
The table below sets forth a listing of potentially dilutive securities that were excluded from the calculation of diluted net loss per share attributable to common shareholders because the impact of including them would have been anti-dilutive or out-of-the-money. Potentially dilutive securities include stock options, restricted stock units, warrants, and other share-settled instruments:

- Stock-Based Compensation
In 2014, the Company adopted the amended and restated Terrestrial Energy Inc. 2014 Stock Options Plan (“the 2014 Plan”). In connection with the Company’s redomestication to Delaware, outstanding awards under the 2014 Plan were assumed by the Terrestrial Energy Delaware Inc. 2024 Stock Option Plan, which was most recently amended and restated in October 2024, as the Terrestrial Energy Inc. Second Amended and Restated 2024 Stock Option Plan. In October 2025, the Company adopted the 2025 Equity Incentive Plan, effective immediately prior to the closing of the Business Combination (the “Current Plan”). As of June 30, 2026, the Current Plan authorizes the Company to award equity awards resulting in the issuance of up to 38,347,872 shares of common stock. The Current Plan provides for grants of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and other awards to employees, non-employee directors, consultants and advisors of the Company.

- Segment Information

Operating segments are defined as components of an enterprise that engage in business activities from which it may recognize revenues and incur expenses, and for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker, or group, in deciding how to allocate resources and assess performance.
The Company’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer in accordance with ASC 280-10-50-5, who reviews the assets, operating results, and financial metrics for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that there is onlyone reportable segment.
The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the consolidated statement of operations as net income or loss. The measure of segment assets is reported on the consolidated balance sheet as total assets when evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:
