Description of the Company and Basis of Presentation	Description of the Company and Basis of Presentation Description of the Company OneSpan provides security, identity, electronic signature (“e-signature”) and digital workflow solutions that protect and facilitate digital transactions and agreements. The Company delivers products and services that automate and secure customer-facing and revenue-generating business processes for use cases ranging from simple transactions to workflows that are complex or require higher levels of security. The Company’s solutions help its customers ensure the integrity of the people and records associated with digital agreements, transactions, and interactions in industries including banking, financial services, healthcare, and professional services. OneSpan has operations in Austria, Australia, Belgium, Canada, China, France, Japan, The Netherlands, Singapore, Switzerland, the United Arab Emirates, the United Kingdom (U.K.), and the United States (U.S.). Business Transformation In December 2021, the Company's Board of Directors approved a restructuring plan (the "restructuring plan") designed to advance the Company's operating model, streamline its business, improve efficiency, and enhance its capital resources. The first phase of this restructuring plan began and was substantially completed during the three months ended March 31, 2022. In May 2022, the Company's Board of Directors announced a three-year strategic transformation plan that began on January 1, 2023 (the "2022 strategic plan"). In conjunction with the 2022 strategic plan and to enable a more efficient capital deployment model, effective with the quarter ended June 30, 2022, the Company began reporting under the following two lines of business, which are its reportable operating segments: Digital Agreements and Security Solutions. For further information regarding the Company’s reportable segments, see Note 3, Segment Information. During the quarter ended June 30, 2023, the Company determined that it was unlikely to achieve the revenue growth levels set forth in its 2022 strategic plan within the contemplated three-year timeframe. A number of factors contributed to the challenges achieving the originally planned growth levels, particularly in Digital Agreements, on the timeframes set forth in the 2022 strategic plan. In response to these challenges, the Company modified its strategy to focus more heavily on improving profitability margins across the business. To this end, in August 2023, the Company’s Board approved cost reduction actions (the “2023 Actions”) to seek to drive higher levels of profitability while maintaining the Company’s long-term growth potential. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of OneSpan and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements, and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the results of the interim periods presented. Operating results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Estimates and Assumptions The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Translation and Transactions The financial position and results of operations of the majority of the Company’s foreign subsidiaries are measured using the local currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. Dollars using current exchange rates as of the balance sheet date. Revenue and expenses are translated at average exchange rates prevailing during the year. Translation adjustments arising from differences in exchange rates are charged or credited to other comprehensive income (loss). Gains and losses resulting from foreign currency transactions are included in the condensed consolidated statements of operations in other (expense) income, net. Foreign exchange transaction losses aggregated to $2.0 million and $1.8 million for the three and nine months ended September 30, 2024, respectively. Foreign exchange transaction losses aggregated to $0.1 million and $0.5 million for the three and nine months ended September 30, 2023, respectively.
