Nova Royalty Acquisition

On December 1, 2023, the Company closed an arrangement agreement whereby the Company acquired all of the issued and outstanding shares of Nova Royalty Corp. (TSX-V: NOVR) ("Nova") pursuant to a plan of arrangement. Pursuant to the terms and conditions of the arrangement agreement between the Company and Nova dated September 7, 2023 (the "Arrangement Agreement"), Nova shareholders received 0.36 of a Common Share for each Nova common share held prior to the Nova acquisition, for a total of 33,893,734 Common Shares issued. In accordance with the Arrangement Agreement, each Nova restricted share unit vested into a Nova common share at the close of the Nova acquisition and was exchanged for 0.36 of a Metalla Common Share for a total of 741,597 Common Shares issued, and each Nova stock option was replaced with a fully vested replacement Metalla option. All replacement options were adjusted as per the terms of the Arrangement Agreement and are exercisable into Metalla Common Shares.

Concurrent with closing of the Nova acquisition on December 1, 2023, the Company drew down from its loan facility with Beedie Investments Ltd. ("Beedie") (Note 6) an amount equal to the principal and unpaid interest and fees outstanding under Beedie's ‎convertible loan agreement with Nova (the "Nova Loan Facility") to refinance and retire the Nova Loan Facility (Note 6). Upon completion of the Nova acquisition, existing Metalla and Nova shareholders owned approximately 60.41% and 39.59% of the combined company, respectively. Following the completion of the acquisition, Nova became a wholly owned subsidiary of Metalla.

For accounting purposes, the Company determined the acquisition of Nova did not meet the definition of business combination under IFRS 3 - Business Combinations. Accordingly, the transaction was accounted for as an asset acquisition under relevant IFRS standards with a closing date of December 1, 2023. Under this method the Company is required to recognize identifiable assets and liabilities at their individual fair values and any transaction costs are capitalized as part of the acquisition, with no goodwill recognized.

To estimate the fair value of the mineral interest acquired, management used discounted cash flow models and a market-based approach. Management applied significant judgment in determining the fair value of the mineral interests, including the use of significant assumptions, such as discount rates, long-term forecast commodity prices, and future production of operator mineral reserves and resources information for the portfolio of mineral stream and royalty agreements. Future production and operator mineral reserves and resources information are based on information compiled by appropriately qualified persons. The assets and liabilities acquired included mineral interests of $131.0 million, current assets of $1.0 million, and current liabilities of $6.2 million. Below is a reconciliation of the purchase consideration for the Nova acquisition along with the total assets acquired, net of liabilities assumed.

Number of Metalla Shares issued to Nova shareholders		33,893,734
