Basis of presentation and consolidation

The accompanying unaudited condensed consolidated financial statements included herein have been prepared in conformity with generally accepted accounting principles in the United States ("GAAP") and under the rules and regulations of the United States Securities and Exchange Commission ("SEC") for interim reporting. The accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, that are necessary to present fairly the Company's financial position, results of operations, and cash flows. The condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosures of the Company normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted under the SEC's rules and regulations. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes thereto for the year ended December 31, 2025, included in the Company's Annual Report on Form 10-K, as amended, originally filed with the SEC on March 25, 2026 (the "2025 Annual Report").

Foreign operations remeasurement and translation

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions, and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates, are generally recognized in the condensed consolidated statements of operations and comprehensive loss. The results and financial position of foreign operation which has functional currency different from presentation currency are translated into the presentation currency as follows: assets and liabilities are translated at the closing rate at the date of that statement of financial position, income and expenses are translated at average exchange rates, and all resulting translated exchange differences are recognized in a separate component of other comprehensive loss within the condensed consolidated statement of changes in shareholders equity.

Use of estimates

The preparation of these condensed consolidated financial statements in accordance with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements, and the reported amounts of income and expenses during the reporting period. Such estimates include the valuation of stock-based awards, the incremental borrowing rate used to discount the Company's operating lease liabilities, fair value of the Company's debentures and warrants, valuation allowance on deferred tax assets, all of which are management's best estimates.

By their nature, these estimates are subject to measurement uncertainty and the effect on the financial statements of changes in estimates in future years could be significant. Management believes that the estimates utilized in preparing the financial statements are reasonable, however, actual results could differ from those estimates.

Operating segments

Operating segments are identified as components of an entity about which separate discrete financial information is available for evaluation by the chief operating decision-maker ("CODM") in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business in one operating segment.

Recently issued accounting pronouncements

In November 2024, the FASB issued ASU 2024-03 "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures" to provide greater transparency about the components of specific expense categories in the income statements. The effective dates of ASU 2024-03 were subsequently clarified by ASU 2025-01. ASU 2025-01 is effective for our annual period beginning January 1, 2027, with early adoption permitted. We are currently evaluating the impact of adopting the amendment on the Company's financial statements.

There were no other significant updates to the recently issued accounting standards which may be applicable to the Company. Although there are several other new accounting pronouncements issued or proposed by the FASB, the Company does not believe any of those accounting pronouncements have had or will have a material impact on its financial position or operating results.
