Item 1.01 Conflict Minerals Disclosure and Report

Kirby Corporation (the “Company”), along with all of its subsidiaries, is committed to sourcing products in accordance with the law and expects suppliers to do the same. The Company has adopted a conflict minerals policy, which has been communicated internally to relevant personnel and to suppliers as described herein. The policy and a copy of this Form SD are available at https://investors.kirbycorp.com/corporate-governance/governance-overview. The information on the Company’s web site does not constitute part of this Form SD. Certain terms used herein are defined in Item 1.01(d) of Form SD.

Through its marine transportation segment, the Company is the nation’s largest domestic tank barge operator, transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, and coastwise along all three United States coasts. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. Through the Company’s distribution and services segment, the Company provides after-market service and replacement parts for engines, transmissions, reduction gears, and related equipment used in oilfield services, marine, power generation, on-highway, and other industrial applications. The Company also rents equipment including generators, industrial compressors, high capacity lift trucks, and refrigeration trailers for use in a variety of industrial markets, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, manufactures cementing and pumping equipment as well as coil tubing and well intervention equipment, electric power generation equipment, specialized electrical distribution and control equipment, and high capacity energy storage/battery systems for oilfield service and railroad customers.

The Company has determined that tin, tungsten, tantalum, and/or gold (“3TG”) may be necessary to the functionality or production of one or more products manufactured by the Company or contracted by the Company to be manufactured in its distribution and services segment or in its shipyard subsidiary within its marine transportation segment, and therefore the Company has conducted a reasonable country of origin inquiry in good faith that is reasonably designed to determine whether any of the 3TG in its products originated in the Democratic Republic of the Congo or an adjoining country, or are from a recycled or scrap sources.

The products that the Company manufactures are complex, typically containing numerous products from many suppliers. The Company has relationships with a significant number of suppliers throughout the world and there are generally multiple tiers between the 3TG mines and the Company’s direct suppliers. As a result, the Company must rely on its direct suppliers to work with upstream suppliers in order that they may provide the Company with accurate information about the origin of 3TG in the products the Company purchases from its direct suppliers.

Because of the complexity and size of the Company’s supply chain, it was not practicable to conduct a survey of all of the Company’s suppliers. For 2023, 399 of the Company’s suppliers were identified by the Company’s relevant business units in its distribution and services segment or in its shipyard subsidiary within its marine transportation segment as potentially supplying products that contain 3TG. To determine whether 3TG are (i) contained in products manufactured by the Company or contracted by the Company to be manufactured by the Company and (ii) originated in in the Democratic Republic of the Congo or an adjoining country, the Company retained Assent Compliance (“Assent”), a third-party service provider, to assist in reviewing its supply chain and identifying risks. The Company provided a list composed of suppliers and parts associated with the in-scope products to Assent for upload to the Assent Compliance Manager (“ACM”). To collect data on the materials’ sources of origin procured by the supply chain, the Company utilized the Responsible Minerals Initiative Conflict Minerals Reporting Template version 6.31 or higher (“CMRT”) to conduct a survey of all in-scope suppliers. During the supplier survey, the Company contacted suppliers via the ACM. The ACM provides functionality that meets The Organization for Economic Co-Operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and the related supplements process expectations for 3TG by evaluating the quality of each supplier response and assigning a health score based on the supplier’s declaration of process engagement. As part of the review process, the in-scope suppliers were requested to provide specified information regarding the inclusion of conflict minerals in the products supplied to the Company or its subsidiaries and the country of origin thereof, and, upon request, were provided a copy of the Company’s current conflict minerals policy. Each CMRT was evaluated for consistency, completeness, and accuracy and, in certain circumstances, further inquiries were made to clarify or improve the quality of the responses. Moreover, suppliers providing no response or an inadequate response were subject to additional written or oral requests for information. Information available from other sources (public and private) regarding the use and country of origin of conflict minerals in such suppliers’ products was also obtained and reviewed.

Based on responses received, the Company determined that 3TG present in certain of its products may have originated in the Democratic Republic of the Congo or an adjoining country and may not be from scrap or recycled sources. The Company has elected not to file disclosure under Item 1.01(c) of Form SD in accordance with the “Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule” issued by the Division of Corporation Finance of the Securities and Exchange Commission on April 7, 2017.
