Description of the Company and Basis of Presentation	Description of the Company and Basis of Presentation Description of the Company OneSpan delivers cutting-edge solutions in two key areas: advanced secure authentication, which is provided through its Security Solutions business unit, and digital agreements, which is provided through its Digital Agreements business unit. The Company's secure authentication solutions protect devices, users, and applications with robust multi-factor and passwordless authentication and other fraud prevention technologies. Its digital agreements solutions combine identity verification, electronic signatures, and digital workflows to streamline agreements, enhance compliance, and accelerate business processes. OneSpan empowers organizations to automate and secure both customer-facing and revenue-generating processes, supporting a wide range of use cases—from simple transactions to complex workflows requiring elevated security. 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 Developments The Company's two business units, Security Solutions and Digital Agreements, are also its reportable operating segments. During 2022 and the first half of 2023, the Company was operating under a three-year strategic plan that focused on driving revenue growth in Digital Agreements. However, in mid-2023, the Company determined it was unlikely to achieve the revenue growth levels set forth in that strategic plan within the contemplated three-year timeframe due to a number of factors, including increasing maturity and competitiveness in the market for e-signature solutions, limited awareness of the OneSpan brand among buyers of e-signature tools, and higher pricing aggressiveness from competitors. 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 of Directors approved additional restructuring actions designed to drive higher levels of profitability while maintaining the Company's long-term growth potential. The Company now plans to drive profitable, efficient growth in both operating segments, with a particular emphasis on growing subscription revenue and sales of high-margin software solutions. Dividends On December 16, 2024, the Company's Board of Directors declared a quarterly cash dividend as part of the initiation of a recurring quarterly dividend program. The initial quarterly cash dividend of $0.12 per share was paid on February 14, 2025 to shareholders of record as of the close of business on January 31, 2025. The declaration and payment of future dividends is subject to the sole discretion of the Board of Directors. Basis of Presentation The Company’s consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). Principles of Consolidation The consolidated financial statements include the accounts of OneSpan Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of 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. The Company regularly assesses its estimates. Estimates are based on historical experience and on various other market-specific and relevant assumptions that the Company believes to be reasonable under the circumstances. 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 consolidated statements of operations in other income (expense), net. Foreign exchange transaction losses aggregated to $0.9 million, $1.1 million, and $1.9 million in 2024, 2023, and 2022, respectively.
