+Added: We believe this represents a significant milestone in Terrestrial Energy’s commercialization pathway, leveraging the program’s fast-track approach to advance the licensing and deployment of the Company’s proprietary IMSR technology.
+Added: DOE Advanced Nuclear Fuel Line Pilot Project
+Added: On September 30, 2025, the Company announced that it had been selected for the DOE’s Advanced Nuclear Fuel Line Pilot Project, established by the Trump administration’s May 2025 executive order to fast-track commercial licensing activities for small and modular nuclear plants that use advanced reactor technologies, expediting their broad deployment.

+Added: Together, these agreements are intended to support the commercialization of the Company's IMSR Plant.
Results of Operations
−Removed: We have neither engaged in
−Removed: any operations nor generated any revenues to date.
−Removed: Our only activities from April 4, 2024 (inception) through December 31, 2024 were organizational
−Removed: activities, those necessary to prepare for the Initial Public Offering, described below, and, after our Initial Public Offering, identifying
−Removed: a target company for a business combination.
−Removed: We do not expect to generate any operating revenues until after the completion of our business
−Removed: We generate non-operating income in the form of interest income on marketable securities held in the trust account.
−Removed: expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due
−Removed: diligence expenses.
−Removed: For the period from April
−Removed: 4, 2024 (inception) through December 31, 2024, cash used in operating activities was $318,768.
−Removed: Net income of $3,408,788 was affected by
−Removed: operating costs paid by Sponsor in exchange for issuance of Class B founder shares of $12,463, payment of operation costs through promissory

−Removed: Factors That May Adversely Affect our Results
−Removed: of Operations
−Removed: Our results of operations
−Removed: and our ability to complete an initial business combination may be adversely affected by various factors that could cause economic uncertainty
−Removed: and volatility in the financial markets, many of which are beyond our control.
−Removed: Our business could be impacted by, among other things,
−Removed: downturns in the financial markets or in economic conditions, increases in oil prices, inflation, increases in interest rates, supply
−Removed: chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the
−Removed: military conflicts in Ukraine and the Middle East.

+Added: Other (expense) income
+Added: Net loss before income taxes
+Added: Income tax expense
+Added: During 2024, the Company provided engineering services to a customer, which was recognized over time as the services were performed.
+Added: The Company’s contracts with customers are typically to provide a significant service by integrating a complex set of agreed tasks into a single deliverable.
+Added: Consequently, the entire contract is accounted for as one performance obligation.
+Added: The Company recognizes revenue from engineering services over time using an input method as performance obligations have no alternative use for the Company and the contracts would require payment to be received for the time and effort spent by the Company on progressing the contracts in the event of the customer cancelling the contract prior to completion for any reason other than the Company’s failure to perform its obligations under the contract.
+Added: Specifically, labor hours incurred are used to measure progress towards complete satisfaction of the service.
+Added: This is considered a faithful depiction of the transfer of services as the contracts are initially priced on the basis of anticipated hours to complete the projects and, therefore, also represents the amount to which the Company would be entitled based on its performance to date.
+Added: Revenue for the years ended December 31, 2025 and 2024 was $0.0 million and $0.3 million, respectively.
+Added: The decrease in revenue in 2025 is attributed to the completion of a contract with a customer in the oil and gas sector for pre-construction and use-specific engineering services, which was completed during 2024 and did not provide any revenue in 2025.
+Added: Operating Expenses
+Added: Research and development expense
+Added: R&D expenses represent costs incurred to design and engineer the IMSR Plant, including the costs of developing design tools.
+Added: All research and development costs related to product development are expensed as incurred.
+Added: R&D expense for the years ended December 31, 2025 and 2024 was $9.8 million and $5.2 million, respectively.
+Added: The increase in 2025 is attributed to an increase in R&D activities performed by the Company in 2025, compared to 2024, as the Company increased its expenditures in testing activities and expanded headcount.
+Added: General and administrative expense
+Added: General and administrative expenses consist of costs, such as rent or lease costs, legal, audit and accounting services, and other professional fees, marketing costs, stock compensation, as well as personnel-related expenses for employees, executives and contractors.
+Added: General and administrative expense for the years ended December 31, 2025 and 2024 was $14.3 million and $4.2 million, respectively.
+Added: The increase in 2025 compared to 2024 is primarily attributable to additional stock-based compensation expense associated with stock options and restricted stock units issued, along with overall operational growth including headcount as part of the business growth strategy.
+Added: Depreciation and amortization
+Added: Depreciation and amortization consist primarily of depreciation of our computer software and equipment and amortization of our patents and trademarks.
+Added: Depreciation and amortization expense for the years ended December 31, 2025 and 2024 was $1.2 million and $1.3 million, respectively.
+Added: The decrease in 2025 was primarily due to certain fixed assets becoming fully depreciated in fiscal 2024.
+Added: Other Income and Expenses
+Added: Government Grants
+Added: Government grants decreased by $0.4 million, or 54% for the year ended December 31, 2025, as compared to the year ended December 31, 2024.
+Added: Interest expense and Interest expense - related parties
+Added: Interest expense and interest expense - related parties increased by $3.0 million, or 231%, for the year ended December 31, 2025 compared to the year ended December 31, 2024.
+Added: The increase was primarily due to the issuance of convertible debt securities by the Company in the third and fourth quarters of 2024 and the first quarter of 2025 which accrued interest expense and the write-off of debt discount for a portion of 2024, and for ten months of the year in 2025.
+Added: Additionally, average borrowings outstanding were higher during 2025 compared to 2024.
+Added: Interest and Dividend Income
+Added: Interest and dividend income increased by $1.2 million for the year ended December 31, 2025 compared to the same period in 2024 as a result of higher short-term investment balances.
+Added: Foreign exchange gain (loss)
+Added: Foreign exchange gain (loss) decreased by $0.7 million for the year ended December 31, 2025 compared to the same period in 2024 due to the volatility of the US dollar to Canadian dollar exchange rate.

−Removed: documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.
−Removed: We have until August 19, 2026
−Removed: to consummate the initial Business Combination (assume no extensions).
−Removed: If we do not complete a Business Combination, we will trigger an
−Removed: automatic winding up, dissolution and liquidation pursuant to the terms of the Amended and Restated Memorandum and Articles of Association.
−Removed: Notwithstanding management’s belief that we would have sufficient funds to execute its business strategy, there is a possibility
−Removed: that business combination might not happen within the 24-month period from the date of the auditors’ report.
−Removed: In connection with our assessment of going concern considerations in accordance with ASC 205-40, Going Concern, as of December 31, 2024,
−Removed: we may need to raise additional capital through loans or additional investments from Sponsor, stockholders, officers, directors, or third
−Removed: Our officers, directors and Sponsor may, but are not obligated to, loan us funds, from time to time or at any time, in whatever

−Removed: We cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.
−Removed: Management plans to
−Removed: address this uncertainty through a Business Combination.

−Removed: Critical Accounting Estimates
−Removed: The preparation of financial
−Removed: statement and related disclosures in conformity with accounting principles generally accepted in the United States of America requires
−Removed: management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets
−Removed: and liabilities at the date of the financial statement, and income and expenses during the periods reported.
−Removed: Making estimates requires
−Removed: management to exercise significant judgement.
−Removed: It is at least reasonably possible that the estimate of the effect of a condition, situation
−Removed: or set of circumstances that existed at the date of the financial statement, which management considered in formulating its estimate,
−Removed: could change in the near term due to one or more future confirming events.
−Removed: Accordingly, the actual results could materially differ from

−Removed: to the chief operating officer decision maker (“CODM”), as well as the aggregate amount of other segment items included in
−Removed: the reported measure of segment profit or loss.
−Removed: The ASU requires that a public entity disclose the title and position of the
−Removed: CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding
−Removed: how to allocate resources.
−Removed: Public entities will be required to provide all annual disclosures currently required by Topic 280 in
−Removed: interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments
−Removed: in this ASU and existing segment disclosures in Topic 280.
−Removed: This ASU is effective for fiscal years beginning after
−Removed: December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted.

−Removed: financial statement.

+Added: The Company’s future capital requirements will depend on many factors, including the timing and extent of spending to support further sales and marketing, research and development efforts, the Company’s commercial development and deployment of its IMSR Plant, and future revenues.
+Added: The Company may seek to obtain additional financing to commercialize the IMSR Plant technology through possible public or private equity offerings, debt financings, corporate collaborations, and other means.
+Added: We believe that we have sufficient cash and cash equivalents and investments, along with continued access to capital markets, to satisfy our cash requirements for the next 12 months and beyond based on current operating plans.

+Added: We consider an accounting judgment, estimate or assumption to be critical when (1) the estimate or assumption is complex in nature or requires a high degree of judgment and (2) the use of different judgments, estimates and assumptions could have a material impact on the consolidated financial statements.
+Added: See Note 2, Significant Accounting Policies, in our accompanying consolidated financial statements for a description of our significant accounting policies.
+Added: Accordingly, these are the policies and estimates we believe are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations:
+Added: Foreign Currency
+Added: The Company’s reporting currency is the US dollar.
+Added: The functional currency of each subsidiary is determined by the currency of the primary economic environment in which the entity operates.
+Added: The functional currency of TEON is the Canadian dollar, 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 United States dollar.
+Added: Assets and liabilities of the operating subsidiaries are translated at the spot rate in effect at the applicable reporting date.
+Added: Revenues and expenses of the operating subsidiaries are translated at the average exchange rates in effect during the applicable period.
+Added: The resulting foreign currency translation adjustment is recorded as Accumulated other comprehensive income (loss), which is reflected as a separate component of Stockholders’ Equity.
+Added: The functional currency is translated into U.S.
+Added: 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 fiscal year.
+Added: 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.
+Added: 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.
+Added: The translation adjustments are deferred as a separate component of equity in “Accumulated other comprehensive income (loss)”.
+Added: 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 consolidated statements of operations and comprehensive loss.
+Added: Fair Value Measurements
+Added: 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.
+Added: 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.
+Added: Observable inputs are from sources independent of the Company.
+Added: 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.
+Added: 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.
+Added: The hierarchy is broken down into three levels:
+Added: Inputs are quoted prices in active markets for identical assets or liabilities.
+Added: 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.
+Added: Inputs are unobservable for the asset or liability.
+Added: The carrying amounts of certain financial instruments, such as cash equivalents, prepaid expenses and other current assets, short-term investments, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities.
+Added: Convertible Notes
+Added: The Company may enter into convertible notes, some of which contain, predominantly, fixed rate conversion features, whereby the outstanding principal and accrued interest may be converted by the holder, into common shares at a fixed discount to the market price of the common stock at the time of conversion.
+Added: In this case, the convertible notes represent a financial instrument other than an outstanding share that embodies a conditional obligation that the issuer must or may settle by issuing a variable number of its equity shares.
+Added: The Company records the convertible note liability at its fixed monetary amount by measuring and recording a premium, as applicable, on the convertible notes date in accordance with ASC Topic 480, Distinguishing Liabilities from Equity (“ASC 480”).
+Added: The Company reviews the terms of warrants to purchase its common stock to determine whether warrants should be classified as liabilities or stockholders’ deficit in its consolidated balance sheets.
+Added: In order for a warrant to be classified in stockholders’ deficit, the warrant must be (i) indexed to the Company’s equity and (ii) meet the conditions for equity classification.
+Added: If a warrant does not meet the conditions for stockholders’ deficit classification, it is carried on the consolidated balance sheets as a warrant liability measured at fair value, with subsequent changes in the fair value of the warrant recorded in other items in the consolidated statements of operations and comprehensive loss.
+Added: 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’ deficit in the consolidated balance sheets, and the amount initially recorded is not subsequently remeasured at fair value.
+Added: Stock-Based Compensation
+Added: The Company accounts for stock-based compensation arrangements granted to employees in accordance with ASC 718, “Compensation:
+Added: 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.
+Added: Equity-based compensation expense is only recognized for awards subject to performance conditions if it is probable that the performance condition will be achieved.
+Added: The Company accounts for forfeitures when they occur.
+Added: The Company uses the Black-Scholes option pricing model to determine the grant date fair value of its stock options granted.
+Added: 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.
+Added: 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.
+Added: The expected term is computed using the simplified method as the Company’s best estimate given its lack of actual exercise history.
+Added: The Company has selected a risk-free rate based on the implied yield available on U.S.
+Added: Treasury securities with a maturity equivalent to the expected exercise term of the stock option.
+Added: The Company grants restricted stock units (“RSUs”) to employees and non-employee directors as part of its equity-based compensation program.
+Added: RSUs represent the right to receive shares of the Company’s common stock upon vesting, subject to specified service and/or performance conditions.
+Added: 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.
+Added: The Company accounts for RSUs in accordance with ASC 718, Compensation—Stock Compensation.
+Added: 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.
+Added: 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.
+Added: The Company accounts for forfeitures as they occur.
+Added: Upon vesting, each RSU is converted into one share of the Company’s common stock.
+Added: The Company may withhold shares to satisfy statutory tax withholding requirements.
+Added: The issuance of shares upon vesting results in an increase to common stock and additional paid-in capital.
+Added: Government Grants
+Added: Government grants are recognized where there is reasonable assurance that the grant will be received, and all attached conditions will be complied with.
+Added: 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.
+Added: 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.
+Added: Merger and Reverse Recapitalization
+Added: Our consolidated financial statements reflect the results of the Merger, which was accounted for as a reverse recapitalization in accordance with U.S.
+Added: The accounting for the Merger required management to make significant estimates and judgments, particularly in identifying the accounting acquirer and evaluating the classification of certain financial instruments.
+Added: Under the guidance in ASC 805 — “Business Combinations,” the determination of the accounting acquirer required management to consider a variety of factors, including the relative voting rights of the pre-combination shareholders, the composition of the board of directors and senior management of the combined entity, and the intended purpose and substance of the transaction.
+Added: After considering this guidance, the Merger was accounted for as a reverse recapitalization, with no goodwill or intangible assets recognized.
+Added: The net assets of the combined entity are stated at historical cost, and the shares and per-share information presented in the consolidated financial statements were retroactively adjusted to reflect the exchange ratio established in the merger agreement.
+Added: Because the accounting for the Merger and reverse recapitalization involved estimates that relied on management’s assumptions regarding market conditions, valuation methodologies, and the interpretation of complex contractual terms, it represents a critical accounting estimate.
+Added: Recently Adopted Accounting Standards
+Added: A discussion of recently issued accounting standards applicable to the Company is described in Note 2, Recent Accounting Pronouncements, in the notes to our audited consolidated financial statements as of and for the years ended December 31, 2025 and 2024 contained elsewhere in this annual report.
+Added: Emerging Growth Company Status
+Added: In April 2012, the JOBS Act was enacted.
+Added: Section 107(b) of the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards.
+Added: Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.
+Added: The Company has elected to take advantage of the extended transition period to comply with new or revised accounting standards and to adopt certain of the reduced disclosure requirements available to emerging growth companies.
+Added: As a result of the accounting standards election, the Company will not be subject to the same implementation timing for new or revised accounting standards as other public companies that are not emerging growth companies which may make comparison of its financials to those of other public companies more difficult.
+Added: The Company expects to retain its emerging growth company status until the earliest of:
+Added: ● The end of the fiscal year in which its annual revenues exceed $1.2 billion;
+Added: ● The end of the fiscal year in which the fifth anniversary of its public company registration has occurred;
+Added: ● The date on which it has issued more than $1.0 billion in non-convertible debt during the previous three-year period;
+Added: ● The date on which it qualifies as a large accelerated filer.
+Added: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
+Added: Not applicable.
