Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2022, which are included with the Company’s Annual Report on Form 10-K and related amendments filed with the United States Securities Exchange Commission (“SEC”). Furthermore, the Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the years ended December 31, 2022 and 2021, included in the Company’s Annual Report on Form 10-K filed with the SEC. Since the date of those audited consolidated financial statements, there have been no changes to the Company’s significant accounting policies except for the Company’s accounting treatment of deferred financing costs for common stock issuances, further described below.

Common stock issuance costs are incremental costs directly associated with an offering of securities. These costs typically include fees paid to bankers or underwriters, attorneys, accountants, as well as printers and other third parties. Prior to the effective date of an offering of equity securities, specific incremental costs directly attributable to a proposed or actual offering of securities may be deferred and charged against the gross proceeds of the offering.  The Company capitalizes these deferred financing costs as prepaid expenses and other current assets in the accompanying unaudited interim condensed consolidated balance sheets until the completion of the offering, unless the offering is abandoned, at which time the deferred financing costs will be recognized in the unaudited condensed consolidated statements of operations.  During the three and six months ended June 30, 2023, the Company recognized general and administrative expenses of $0.8 million related to abandoned offerings.

The accompanying unaudited interim condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements for the periods presented reflect all adjustments, consisting of only normal recurring adjustments, necessary to fairly present the Company’s financial position, results of operations, and cash flows. The December 31, 2022 condensed consolidated balance sheet was derived from audited financial statements, but does not include all GAAP disclosures. The unaudited condensed consolidated financial statements for the interim periods are not necessarily indicative of results for the full year.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgements and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions made in the accompanying unaudited condensed consolidated financial statements include, but are not limited to, the accrual for research and development expenses and the valuation of warrant liabilities and embedded derivative liabilities. Actual results could differ from those estimates, and such differences could be material to the unaudited condensed consolidated financial statements.

Foreign Currency

Comprehensive loss is defined as a change in equity of a business enterprise during a period, resulting from transactions from non-owner sources. As of June 30, 2023, the reporting currency of the Company is the United States dollar (“US$” or “$”) and the functional currency of the Company is the Canadian dollar (“C$”). The assets and liabilities of the Company are translated to US$ at exchange rates in effect at the balance sheet date. All income statement accounts are translated at average exchange rates. Resulting foreign currency translation adjustments are recorded directly in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity (deficit). Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations and comprehensive loss when realized and are not material for the three and six months ended June 30, 2023 and 2022.

Recent Accounting Pronouncements

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (“Subtopic 470-20 ”) and Derivatives and Hedging Contracts in Entity s Own Equity (“Subtopic 815-40 ”): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred shares. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (i) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (ii) convertible debt instruments issued with substantial premiums for which the premiums are recorded as additional paid-in capital. ASU 2020-06 also amends the guidance for the derivatives

scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective for the Company for fiscal years beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the potential impact adopting ASU 2020-06 will have on the Company’s consolidated financial statements and related disclosures.

In June 2016, and in later clarifying amendments, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The pronouncement changes the impairment model for most financial assets and will require the use of an “expected loss” model for instruments measured at amortized cost. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. ASU 2016-13 will be effective for the Company for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company adopted this standard effective January 1, 2023 with no material impact on the Company’s unaudited interim condensed consolidated financial statements.
