The accompanying Financial Statements have been prepared by management in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete consolidated financial statements. In the opinion of management, all adjustments, consisting principally of normal recurring adjustments, considered necessary for a fair presentation have been included. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Financial Statements and the accompanying notes. Actual results could differ from these estimates. These Financial Statements should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes for the year ended December 31, 2024, included in our Annual Report on Form
