Conflict Minerals Report

For the Year Ended December 31, 2015


The aerospace part of Butler National’s business is based upon design engineering and installation innovations to enhance and support products related to airplanes and ground support equipment. Certain Butler products contain materials and components which use small amounts of conflict minerals. Due to the depth of the supply chain, Butler is far removed from the sources of ore from which these materials are produced and the smelters or refiners that process those ores. The amount of information available globally on the traceability and sourcing of these ores is limited and Butler must rely on its suppliers to provide us with information on the origin of any conflict minerals contained in components and materials supplied to us.

This report has been prepared by Butler National Corporation (“Butler”) pursuant to Rule 13p-1 promulgated under the Securities Exchange Act of 1934, as amended. This rule imposes certain disclosure obligations on Securities Exchange Commission (“SEC”) registrants, whose manufactured products contain certain minerals (conflict minerals) which are necessary to the functionality or production of such products. “Conflict minerals” are defined as cassiterite, columbite-tantalite, gold, wolframite, and their derivatives which are limited to tin, tantalum and tungsten. The portion of Butler’s business relevant to this report is Aerospace Products, which focuses on two product lines : Aircraft Modifications and Avionics. If a registrant has reason to believe that any of the conflict minerals in their supply chain may have originated in the Democratic Republic of the Congo, or an adjoining country and are not solely from scrap or recycled sources, the registrant must conduct due diligence on the source and chain of custody of such conflict minerals and submit a Conflict Minerals Report to the SEC. This report describes efforts made by Butler to determine the information required with respect to the products manufactured by it through its subsidiaries during calendar year 2015.
