(1) Basis for Preparation of the Condensed Financial Statements

The condensed financial statements included herein have been prepared by Kirby Corporation and its consolidated subsidiaries (“Kirby” or the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including significant accounting policies normally included in annual financial statements, have been condensed or omitted pursuant to such rules and regulations. It is suggested that these condensed financial statements be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Certain reclassifications have been made to reflect the current presentation of financial information.
