1. NATURE OF OPERATIONS

Metalla Royalty & Streaming Ltd. ("Metalla" or the "Company"), incorporated in British Columbia, Canada, is a precious metals royalty and streaming company, which engages in the acquisition and management of gold, silver, and copper royalties, streams, and similar production-based interests. The Company's common shares ("Common Shares") are listed on the TSX Venture Exchange ("TSX-V") under the symbol "MTA" and on the NYSE American ("NYSE") under the symbol "MTA". The head office and principal address is 605 – 200 Burrard Street, Vancouver, British Columbia, Canada.

The Company has incurred a cumulative deficit to date of $71.7 million as at June 30, 2026, and in prior years has had losses from operations for multiple years. Management expects that its cash balance, cash flows from operating activities, and available credit facilities will be sufficient to fund the operations of the Company for at least twelve months from the date of this report. Continued operations of the Company are dependent on the Company's ability to generate positive cash flow in the future, receive continued financial support, and/or complete external financing.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES

(a) Statement of Compliance

These condensed interim consolidated financial statements have been prepared using accounting policies in compliance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") applicable to the preparation of interim financial statements, including International Accounting Standard ("IAS") 34, Interim Financial Reporting. These condensed interim consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2025.

(b) Basis of Preparation and Measurement

These condensed interim consolidated financial statements have been prepared on a historical cost basis, except for financial instruments, which have been measured at fair value. In addition, these condensed interim consolidated financial statements have been prepared using the accrual basis of accounting except for cash flow information.

These condensed interim consolidated financial statements are presented in United States dollars, which is the Company's functional currency, and all values are rounded to the nearest thousand United States dollars except as otherwise indicated.

The preparation of financial statements in accordance with IAS 34 requires the use of certain accounting estimates. It also requires management to exercise judgment in applying the Company's accounting policies. Information about significant areas of estimation uncertainty and judgments made by management in preparing the condensed interim consolidated financial statements are unchanged from those disclosed in the Company's most recent annual consolidated financial statements for the year ended December 31, 2025.

(c) Change in Accounting Policy

The accounting policies applied in the preparation of these condensed interim consolidated financial statements are consistent with those applied and disclosed in the Company's most recent annual consolidated financial statements for the year ended December 31, 2025, except for the change as discussed below.

The Company adopted amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures effective January 1, 2026. These amendments include clarifications to the derecognition requirements for financial liabilities settled through electronic payment systems, additional guidance on the classification of financial assets with contingent features, and additional disclosure requirements for financial instruments.

5. LOANS PAYABLE

 (1) The closing balance at December 31, 2025, includes $0.2 million of accrued interest included in accounts payable.

Revolving Credit Facility

On June 24, 2025, Metalla entered into a definitive agreement with the Bank of Montreal ("BMO") and National Bank Financial ("NBF") for a revolving credit facility of $40.0 million (the "RCF"), with an accordion feature for an additional $35.0 million of availability option, subject to certain conditions, to increase the facility to $75.0 million. Upon close, the Company drew down $13.1 million from the RCF and incurred transaction costs of $1.1 million which will be amortized over the term of the loan.

The RCF is available to finance acquisitions and investments, and for general corporate purposes. The RCF has a maturity date of June 24, 2028, which is extendable annually for one year on the mutual agreement of Metalla, BMO, and NBF. Drawdowns under the RCF can either be USD base rate advances which will bear an interest rate equal to a base rate plus applicable margin, or can be term benchmark advances which will bear an interest rate equal to the Secured Overnight Financing Rate ("SOFR") plus a credit spread adjustment of 0.10%, plus an applicable margin of 2.50% to 3.50% per annum depending on the Company's net leverage ratio.  The undrawn portion of the RCF is subject to a standby fee of 0.56% to 0.79% per annum depending on the Company's net leverage ratio.

The RCF is subject to standard conditions and covenants which include a net leverage ratio, an interest coverage ratio, and a minimum liquidity amount. The Company was in full compliance with all covenants as at June 30, 2026. The RCF is secured by a first-ranking security interest over all present and future property and assets of the Company and its material subsidiaries.

For the three months ended June 30, 2026, the Company recognized interest expenses associated with the RCF of $0.3 million (June 30, 2025 - less than $0.1 million), and recognized finance charges of less than $0.1 million (June 30, 2025 - less than $0.1 million) related to standby fees associated with the RCF.

5. LOANS PAYABLE (CONT'D…)

For the six months ended June 30, 2026, the Company recognized interest expenses associated with the RCF of $0.6 million (June 30, 2025 - less than $0.1 million), and recognized finance charges of $0.1 million (June 30, 2025 - less than $0.1 million) related to standby fees associated with the RCF.

As at June 30, 2026, the amount drawn on the RCF was $13.1 million, the availability under the RCF was $26.9 million, and the transaction costs, net of accumulated amortization were $0.8 million.

Convertible Loan Facility

In March 2019, the Company entered into a convertible loan facility (the "Loan Facility") with Beedie Investments Ltd. ("Beedie") to fund acquisitions of royalties and streams, which was subsequently amended from time to time. The Loan Facility bore interest on amounts advanced and a standby fee on funds available. Funds advanced were convertible into Common Shares at Beedie's option, with the conversion price determined at the date of each drawdown or at the conversion date (in the case of the conversion of accrued and unpaid interest). The Loan Facility was secured by certain assets of the Company.

Effective December 1, 2023, Metalla and Beedie entered into an amended and restated convertible Loan Facility agreement to amend and restate ‎the‎ loan facility (the "A&R Loan Facility"). Pursuant to the A&R Loan Facility, the parties agreed to among other things, increase ‎the A&R Loan Facility from C$25.0 million to C$50.0 million, amend the conversion price of the principal amount outstanding of C$16.4 million to a conversion price of C$6.00 per share, amend the conversion price of any accrued and unpaid interest to a conversion price equal to the market price of the shares of Metalla at the time of conversion, and have any accrued and unpaid fees to not be convertible into Common Shares.

On June 24, 2025, concurrent with the closing of the RCF, the Company fully repaid and retired the A&R Loan Facility.  The final payments to Beedie included a repayment of the principal balance outstanding of C$16.4 million plus C$0.7 million in accrued interest and standby fees.  In connection with the retirement of the A&R Loan Facility, certain assets secured by Beedie were released and there are no further amounts due under the A&R Loan Facility.

On June 24, 2025, upon retirement of the A&R Loan Facility, the Company recorded a $0.7 million loss on extinguishment, which represents the difference between the carrying amount of the A&R Loan Facility on the retirement date and the amount that was paid to retire the A&R Loan Facility.

9. EARNINGS PER SHARE ("EPS")

Diluted earnings per share is calculated using the treasury method which assumes that outstanding stock options, with exercise prices that are lower than the average market price of the Common Shares for the relevant period, are exercised and the proceeds are used to purchase shares of the Company at the average market price of the common shares for the relevant period.

Diluted EPS is calculated based on the following weighted average number of shares outstanding:

As a result of the net losses for the three and six months ended June 30, 2025, all potentially dilutive common shares were antidilutive for the respective periods and thus diluted loss per share is equal to the basic loss per share.

10. RELATED PARTY TRANSACTIONS AND BALANCES

The aggregate value of transactions and outstanding balances relating to key management personnel were as follows:

As at June 30, 2026, the Company had $Nil (December 31, 2025 - $1.8 million) due to directors and management related to remuneration and expense reimbursements. As at June 30, 2026, the Company had $Nil (December 31, 2025 - $Nil) due from directors and management.

12. FINANCIAL INSTRUMENTS

The Company classified its financial instruments as follows:

Fair Value

Financial instruments recorded at fair value on the consolidated statement of financial position are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels:

a) Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities;

b) Level 2 - Inputs other than quoted prices that are observable for assets or liabilities, either directly or indirectly; and

c) Level 3 - Inputs for assets and liabilities that are not based on observable market data.

The fair value hierarchy requires the use of observable market inputs whenever such inputs exist. A financial instrument is classified to the lowest level of the hierarchy for which a significant input has been considered in measuring fair value.

Cash and cash equivalents, accounts receivables (royalty and stream receivables, and other receivables), and accounts payable (trade and other payables), are carried at amortized cost. Their carrying value approximated their fair value because of the short-term nature of these instruments or because they reflect amounts that are receivable to the Company without further adjustments. Marketable securities are carried at fair value and are classified within Level 1 of the fair value hierarchy. Marketable securities are included in prepaid expenses and other on the Company's statement of financial position. There were no transfers between the levels of the fair value hierarchy during the six months ended June 30, 2026, and the year ended December 31, 2025.

The RCF and acquisition payables are carried at amortized cost. The RCF is classified within Level 2 because its applicable interest rate includes an adjustment based on the Company's net leverage ratio and a credit spread adjustment (Note 5). As at June 30, 2026, the fair value of the RCF was $11.6 million (December 31, 2025 - $11.4 million). In prior periods, the Company had derivative loan liabilities embedded in the A&R Loan Facility that were carried at fair value and were classified within Level 3 of the fair value hierarchy, with the retirement of the A&R Loan Facility on June 24, 2025, the Company no longer has any derivative loan liabilities.

12. FINANCIAL INSTRUMENTS (CONT'D…)

Capital Risk Management

The Company's objectives when managing capital are to provide shareholder returns through maximization of the profitable growth of the business and to maintain a degree of financial flexibility relevant to the underlying operating and metal price risks while safeguarding the Company's ability to continue as a going concern. The capital of the Company consists of share capital. The Board of Directors does not establish a quantitative return on capital criteria for management. The Company manages the capital structure and makes adjustments in light of changes in economic conditions and the risk characteristics of the underlying assets. The Company may issue new shares in order to meet its financial obligations. The management of the Company believes that the capital resources of the Company as at June 30, 2026, are sufficient for its present needs for at least the next twelve months. The Company is not subject to externally imposed capital requirements.

Credit Risk

Credit risk arises from cash deposits, as well as credit exposures to counterparties of outstanding receivables and committed transactions. There is no significant concentration of credit risk other than cash deposits. The Company's cash deposits are primarily held with a Canadian chartered bank. Receivables include value added tax due from the Canadian government. The carrying amount of financial assets recorded in the financial statements represents the Company's maximum exposure to credit risk. The Company believes it is not exposed to significant credit risk and overall, the Company's credit risk has not declined from the prior year.

Liquidity Risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk by continuing to monitor forecasted and actual cash flows. The Company has in place a planning and budgeting process to help determine the funds required to support the Company's normal operating requirements on an ongoing basis and its development plans. The Company strives to maintain sufficient liquidity to meet its short-term business requirements, taking into account its anticipated cash flows from royalty and stream interests, its cash on-hand, and its committed liabilities. The maturities of the Company's loan liabilities are disclosed in Note 5. All current liabilities are settled within one year.

Currency Risk

The Company is exposed to the financial risk related to the fluctuation of foreign exchange rates. The Company primarily operates in Canada, Australia, Mexico, and the United States and incurs expenditures in currencies other than United States dollars. Thereby, the Company is exposed to foreign exchange risk arising from currency exposure. The Company has not hedged its exposure to currency fluctuations. Based on the above net exposure, as at June 30, 2026, and assuming that all other variables remain constant, a 1% depreciation or appreciation of the United States dollar against the Canadian dollar, Australian dollar, and Mexican peso would result in an increase/decrease in the Company's pre-tax income of less than $0.1 million.

Interest Rate Risk

Interest rate risk is the risk that the fair value of a financial instrument or cash flows associated with the instrument will fluctuate due to changes in market interest rates. The only financial instrument that is subject to interest rate risk is the RCF (Note 5), which bears a variable interest rate when drawn. The undrawn portion of the RCF is subject to standby charges. There is no significant impact on the Company's pre-tax loss with a 1% increase or decrease in the interest rate charged on the RCF as at June 30, 2026.

12. FINANCIAL INSTRUMENTS (CONT'D…)

Commodity Price Risk

The Company's royalties, streams, and other interests are subject to fluctuations from changes in market prices of the underlying commodities. The market prices of gold, copper, and silver are the primary drivers of the Company's profitability and ability to generate free cash flow. All of the Company's future revenue is not hedged in order to provide shareholders with full exposure to changes in the market prices of these commodities.

13. COMMITMENTS

As at June 30, 2026, the Company had the following contractual obligations, including interest:

(1) Payments required to be made on the RCF based on the closing balance, applicable interest rate, and availability under the RCF as at June 30, 2026.

(2) Cash payment of $1.25 million required for the royalty on the Lama project in January 2027.

(3) Payment of $0.5 million (C$0.75 million) in cash required for a milestone payment under the Hoyle Pond Extension property (Note 4).

In addition to the commitments above, the Company could in the future have additional commitments payable in cash and/or shares related to the acquisition of royalty and stream interests. However, these payments are subject to certain triggers or milestone conditions that have not been met as at June 30, 2026.

14. SEGMENTED INFORMATION

The Company operates in one industry and has one reportable operating segment, consisting of acquiring and managing gold, silver, and copper royalties, streams, and similar production-based interests, which is managed and reviewed by the Company's CEO who is the chief operating decision maker.

Revenue by geographical region includes revenues earned from royalties and streams and is determined by the geographic area of the mining operations giving rise to the royalty revenue. The Company's revenue by geographical area during the three and six months ended June 30, 2026, and 2025 was as follows:

14. SEGMENTED INFORMATION (CONT'D…)

The geographical region of royalties, streams, and other mining interests are determined by the geographic area of the mining operations related to the royalties, streams and other mining interests. As at June 30, 2026, and December 31, 2025, non-current assets were located in the following geographical regions:
