Exhibit 1.01

SigmaTron International, Inc. Conflict Minerals Report For The Year Ended December 31, 2014 This Conflict Minerals Report of SigmaTron International, Inc. (herein referred to as “we,” “our” or “us”) (this “CMR”) is presented in compliance with Rule 13p-1 (“Rule 13p-1”) of the Securities Exchange Act of 1934 (the “1934 Act”) for the year ended December 31, 2014. Please refer to Rule 13p-1, Form SD and the 1934 Act Release No. 34-67716 for definitions to the terms used in this CMR, unless otherwise defined herein. 1. Due Diligence We surveyed our supply chain to gather information and confirm whether Conflict Minerals used in our products are procured from the Covered Countries. This survey was conducted using the CFSI Reporting Template developed jointly by the Electronic Industry Citizenship Coalition (“EICC”) and the Global e-Sustainability Initiative (“GeSI”) (the “Template”). Utilizing the Template, a reasonable country of origin inquiry was conducted across our supply chain to determine the sourcing of the Conflict Minerals used in our products. To date, we have received responses from approximately 90% of our supply chain. Of the responses we have received, approximately 30% of our suppliers are reporting DRC conflict undeterminable and approximately 70% of our suppliers are reporting DRC conflict free. We compiled a list of all smelters and refiners used by our suppliers that have provided responses, including all smelters and refiners which have not completed certification under the EICC/GeSI Conflict Free Smelter program. 192 unique, real smelters or refiners were reported by our suppliers. Of these 192 smelters and refiners, 175 are certified as “conflict free” by the EICC/GeSI Conflict Free Smelter program. After reviewing the 2014 interim and 2014 final reports by the UN Group of Experts on the Democratic Republic of Congo and other publications, we found no reasonable basis for concluding that the uncertified smelters and refiners sourced Conflict Minerals that directly or indirectly finance or benefit armed groups, however we cannot say with certainty that the uncertified smelters and refiners are DRC conflict free. In light of the responses that we have not yet received from our suppliers, in light of the approximately 30% of our suppliers reporting DRC conflict undeterminable, and in light of the 17 uncertified smelters and refiners, our supply chain remains DRC conflict undeterminable at this time for all of our products. We re-communicated to our suppliers that they must (i) familiarize themselves and comply with the regulations set forth in the Dodd-Frank Act; (ii) implement Conflict Mineral policies that are consistent with our policy; (iii) provide us with all necessary declarations; (iv) pass all of the requirements set forth in the Dodd-Frank Act on to their supply chain if they don’t source directly from smelters or refiners; (v) determine the source of the Conflict Minerals they use; and (vi) maintain reviewable business records continued

for not less than seven (7) years supporting the source of Conflict Minerals. We affirmatively notified suppliers that those who are found to be non-compliant to the requirements imposed by the Dodd-Frank Act and our policy shall be reviewed to determine suitability for future business. The use of the Template provided by EICC/GeSI and our other due diligence steps conform in material aspects to the standards set forth by the second edition of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (OECD 2011). In the future, we intend to complete the collection of all survey responses from our suppliers. Additionally, we will continue to assess our suppliers with respect to our compliance requirements referenced above. We have instituted policies and procedures requiring suppliers to provide affirmative notification if they begin sourcing Conflict Minerals from any facilities which have not been identified as “conflict free” by the EICC/GeSI Conflict Free Smelter Program. We have included Conflict Minerals flow-down clauses in all new and renewing supplier contracts. And, we are working with trade associations and industry groups to further improve our due diligence and best practices. 2. Product Description/Overview We manufacture electronic assemblies made up of printed circuit boards, semiconductors and passive electronic components soldered together utilizing tin-based alloys for a wide variety of customers that use electronics in the products they design, manufacture and sell. Our customers serve many different industries. Most of the electronic components we purchase to build the assemblies we manufacture contain one or more of the Conflict Minerals. As a result of the aforementioned in-depth due diligence measures, we have determined that all of our products are DRC conflict undeterminable. Based on lack of all information from our suppliers, based on our suppliers which have provided a DRC conflict undeterminable response, and based on the uncertified smelters and refiners, at this time we cannot identify whether any of the Conflict Minerals contained in our products originated in the Covered Countries and, if so, whether such Conflict Minerals were from recycle or scrap sources, were DRC conflict free or have not been found to be DRC conflict free. Based on the responses received from our suppliers to-date, the following is a list of facilities used to process the necessary Conflict Minerals in our products.
