1) Nature of operations** and basis of presentation**

Trilogy Metals Inc. (“Trilogy” or the “Company”) was incorporated in British Columbia, Canada under theBusiness Corporations Act (British Columbia) on April 27, 2011. The Company is engaged in the exploration and development of mineral properties, through its equity investee Ambler Metals LLC (“Ambler Metals”), with a focus on the Upper Kobuk Mineral Projects (“UKMP”), including the Arctic and Bornite Projects located in Northwest Alaska in the United States of America. The Company also conducts early-stage exploration through a wholly owned subsidiary, 995 Exploration Inc.

These condensed interim consolidated financial statements have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of Trilogy and its wholly owned subsidiaries, NovaCopper US Inc. and 995 Exploration Inc. All intercompany transactions are eliminated on consolidation.

As these condensed interim consolidated financial statements do not contain all of the disclosures required by U.S. GAAP for annual financial statements, these condensed interim consolidated financial statements should be read in conjunction with the annual financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2025 (“Annual Report on Form 10-K”).

2) Summary of significant accounting policies

Investment in Ambler Metals LLC

The Company accounts for its investment in Ambler Metals as an investment in associate. For a variable interest entity (“VIE”) where Trilogy is not the primary beneficiary, we use the equity method of accounting. Management assesses the possibility of impairment in the carrying value of its equity method investment in Ambler Metals whenever events or circumstances indicate that the carrying amount of the investment may not be recoverable. Ambler Metals is a non-publicly traded equity investment owning exploration and development projects. Significant judgments are made in assessing the possibility of impairment. The Company assesses whether there has been a potential triggering event for other-than-temporary impairment by assessing the underlying assets of Ambler Metals for recoverability and assessing whether there has been a change in the development plan or strategy for the projects. If the Company concludes there is sufficient evidence of an other-than-temporary impairment, an assessment of fair value is performed. If the underlying assets are not recoverable, the Company will record an impairment charge equal to the difference between the carrying amount of the equity investment and its fair value. This assessment is subjective and requires consideration at each period end.

Fair value measurement of derivative liability

On October 6, 2025, the Company entered into a binding letter of intent with the U.S. Department of War for their conditional investment of approximately $17.8 million in exchange for 8,215,570 units at a price of $2.17 per unit, with each unit comprising one common share of the Company and¾ of a 10-year warrant. Each full warrant is exercisable to acquireone common share of the Company at a price of $0.01 per share. The Company has accounted for the obligation to issue shares and warrants as a derivative financial instrument under ASC 815-40 and initially measured at fair value. Subsequently, at each period end, the derivative liability is re-measured at fair value with changes recorded in the consolidated statement of loss and comprehensive loss.

Stock-based payments

The Company records share-based compensation awards exchanged for employee, director and certain contractor services at fair value on the date of the grant and expenses the awards over the requisite service period. The fair values of stock options are determined at the time of the grant using a Black-Scholes option pricing model, which takes into account, as of the grant date, the fair market value of the shares, expected volatility, expected dividend yield, the risk-free interest rate, and the expected life of the option. The Company’s estimates may be impacted by certain variables including, but not limited to, stock price volatility, employee stock option exercise behaviors, additional stock option grants, and estimates of forfeitures.

New accounting pronouncements

Issued and Not Effective

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 enhances the transparency and decision usefulness of income tax disclosures through changes to the rate reconciliation and income taxes paid information. The standard is effective beginning with the Company’s Annual Report on Form 10-K for the fiscal year ended November 30, 2026, and subsequent interim periods, with early adoption permitted. The Company is evaluating the impact of ASU 2023-09 on its disclosures in the annual consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11 “Interim Reporting (Topic 270): Narrow Scope Improvements” (“ASU 2025-11”), to improve the guidance for interim reporting and clarify when that guidance is applicable. ASU 2025-11 provides a comprehensive list of required disclosures and also requires entities to disclose events since the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. For the Company, the guidance becomes effective in the first interim reporting period of the fiscal period of the fiscal year ended November 30, 2029. Early adoption is permitted. Management is currently evaluating ASU 2025-11 to determine its impact on the Company’s disclosures.

3) Investment in Ambler Metals LLC

On February 11, 2020, the Company completed the formation of Ambler Metals, a 50/50 joint venture with South32 Limited (“South32”). As part of the formation of the joint venture, Trilogy contributed all its assets associated with the UKMP, including the Arctic and Bornite Projects, while South32 contributed cash of $145.0 million, resulting in each party’s subsidiaries directly owning a 50% interest in Ambler Metals.

Ambler Metals is a company jointly controlled by Trilogy and South32 through afour-member board, of whichtwo members are appointed by Trilogy based on its 50% equity interest. All significant decisions related to the UKMP require the approval of both companies. We determined that Ambler Metals is a VIE because it is expected to need additional funding from its owners for its significant activities. However, we concluded that we are not the primary beneficiary of Ambler Metals as the power to direct its activities, through its board, is shared under the Ambler Metals LLC limited liability company agreement. As we have significant influence over Ambler Metals through our representation on its board, we use the equity method of accounting for our investment in Ambler Metals. Our maximum exposure to loss in this entity is limited to the carrying amount of our investment in Ambler Metals, which, as of May 31, 2026, totaled $112.1 million (November 30, 2025 - $105.3 million).

Trilogy recognized, based on its 50% ownership interest in Ambler Metals, an equity loss equivalent to its pro rata share of Ambler Metals’ comprehensive loss of $2.3 million for the three-month period ended May 31, 2026 (2025 - $0.8 million) and $3.7 million for the six-month period ended May 31, 2026 (2025 - $1.3 million). During the six-month period ended May 31, 2026, Trilogy and South32 each contributed $10.5 million in cash to Ambler Metals to fund its operations. The carrying value of Trilogy’s 50% investment in Ambler Metals as at May 31, 2026 is summarized in the following table.

(c) The following table provides Ambler Metals’ balances on a 100% basis as at May 31, 2026. The Company’s carrying value of the investment in Ambler Metals exceeds its share of the carrying value of the net assets of Ambler Metals as a result of recording the Company’s initial investment in 2020 at fair value.

Ambler Metals’ cash and cash equivalents are held at one bank. The majority of the cash and cash equivalents is uninsured as at May 31, 2026.

(d) The following table summarizes Ambler Metals’ loss for the six-month period ended May 31, 2026.

(e) Related party transactions

During the six-month period ended May 31, 2026, the Company charged $17,800 (2025 - $105,200) related to administration services, accounting services and reimbursements of expenditure paid on behalf of Ambler Metals; all in connection with a service agreement between the Company and Ambler Metals. As at May 31, 2026, $4,600 remains outstanding and is recorded as a receivable. Subsequent to May 31, 2026, the Company funded an additional $6.5 million to Ambler Metals, bringing total funding to $17.0 million.

4) Accounts payable and accrued liabilities

5) Leases

The Company’s lease arrangement consists of an operating lease for the corporate office. On July 1, 2024, the Company entered into afour-year lease for office space expiring in June 2028. The lease hasno extension option. The current monthly lease payment is approximately CDN$9,500 consisting of both base rent and variable operating costs.

Total lease expense recorded within general and administrative expenses was comprised of the following components:

Variable lease costs consist primarily of the Company’s portion of operating costs associated with the office space lease as the Company elected to apply the practical expedient not to separate lease and non-lease components. For the six-month period ended May 31, 2025, variable lease costs have been reduced by a refund received for adjusted operating costs.

As at May 31, 2026, the remaining lease term is 2.0 years. The discount rate used to measure the lease liability is 9%. Judgment was used in the determination of the incremental borrowing rate which included estimating the Company’s credit rating.

Supplemental cash flow information relating to our leases during the six-month period ended May 31, 2026, is as follows:

Future minimum payments relating to the lease recognized in our balance sheet as of May 31, 2026 are as follows:

During the three-month period ended February 28, 2026, the Company granted 1,655,000 stock options (2025 -2,125,000 stock options) at a weighted exercise price of CDN$6.53 (2025 - CDN$1.52) to employees, consultants and directors exercisable for a period offive years with various vesting terms from immediate vesting to vesting over atwo-year period. The fair value attributable to option grants was $2.49 (2025 - $0.59). No grants were made during the three-month periods ended May 31, 2026 and 2025.

The fair value of the stock options recognized in the period has been estimated using the Black-Scholes option pricing model.

During the six-month period ended May 31, 2026, the Company issued 253,334 common shares (2025 –350,000) of the Company on the exercise of stock options with a weighted average price of CDN$1.49 per share. Upon exercise of these stock options, $0.1 million was reclassified from additional paid-in capital related to stock-based compensation to common stock.

The following table summarizes information about the stock options outstanding at May 31, 2026.

The aggregate intrinsic value of vested stock options (the market value less the exercise price) at May 31, 2026 was $29.6 million (2025 - $4.0 million) and the aggregate intrinsic value of exercised stock options for the six-month period ended May 31, 2026 was $0.9 million (2025 - $0.3 million).

Awards under the RSU Plan and DSU Plans will be settled in common shares of the Company with each restricted share unit (“RSU”) and deferred share unit (“DSU”) entitling the holder to receiveone common share of the Company. All units are accounted for as equity-settled awards.

A summary of the Company’s unit plans and changes during the six-month period ended May 31, 2026 is as follows:

7) Fair value accounting

Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the significance of the inputs used in making the measurement. The three levels of the fair value hierarchy are as follows:

• *Level 1– Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 – Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, deposits, and accounts payable and accrued liabilities and the derivative liability. The fair value of the Company’s financial instruments other than derivative liability approximates their carrying value due to the short-term nature of their maturity. The Company’s financial instruments initially measured at fair value and then held at amortized cost include cash and cash equivalents, accounts receivable, deposits, and accounts payable and accrued liabilities. The majority of the Company’s cash and cash equivalents is held withtwo Canadian Financial Institutions and is uninsured as at May 31, 2026.

The derivative liability representing the Company’s obligation to issue shares and warrants to the U.S. Department of War is carried at fair value on a recurring basis. The fair value of the derivative liability is valued on the basis of Level 3 inputs. The estimated fair value at May 31, 2026 of $34.5 million (November 2025 - $30.7 million) is based on the Company’s common stock price of $4.63 at that date, volatility of 82.07%, a risk-free rate of 3.63% and management’s estimate of the equal probability of completion and non-completion of the Ambler Access Project, which is beyond the control of the Company. During the six-month ended May 31, 2026, the Company recorded afair value loss of $3.8 million primarily reflecting a small increase in the Company’s share price in the period. A 10% change in the Company’s stock price affects the gain or loss on the derivative liability by approximately $5.2 million at May 31, 2026. A 10% change in management’s estimate of the likelihood of completion affects the gain or loss on the derivative liability by approximately $1.4 million at May 31, 2026. On March 30, 2026, the Company, South32, Ambler Metals and the United States Department of War agreed to enter into an amendment to the previously disclosed binding letter of intent (“LOI”) dated October 6, 2025. The first amendment extended the completion date of the transaction from March 31, 2026 to May 31, 2026. On May 30, 2026, the parties entered into a second amendment to extend the completion date of the transaction from May 31, 2025 to July 31, 2026. All other terms and conditions of the original LOI remain unchanged.

8) Commitment

The Company has commitments with respect to an office lease requiring future minimum lease payments as summarized in note 5(b) above.

9) Supplemental cash flow information

10) Segment Information

The Company’s operating segments are reported in a manner consistent with the internal reporting provided to its Chief Operating Decision Makers (“CODM”). The CODM, who are responsible for allocating resources and assessing the performance of the operating segments, have been identified as the Chief Executive Officer and Chief Financial Officer. The CODM evaluates the Company’s performance based on the overall results of the Company, including the performance of its investment Ambler Metals, which holds the Upper Kobuk Mineral Projects in Alaska. The Company uses a single U.S. GAAP-consistent measure of segment profit or loss with no reconciling items or measurement differences. Management has concluded that consolidated net income (loss) is the appropriate measure of segment of profit or loss. The CODM does not regularly receive or review discrete segment-level expense categories separate from those presented in the consolidated statements of operations. Accordingly, no significant segment expenses are separately disclosed, as all expenses are included within the consolidated statement of loss.
