Conflict Minerals Report
For The Year Ended December 31, 2016

Introduction

This conflict minerals report (the “Report”) has been prepared pursuant to Rule 13p-1 under the Securities Exchange Act of 1934 (the “Rule”), for the reporting period from January 1 to December 31, 2016.

The Report relates to the process undertaken by MDU Resources Group, Inc. (herein referred to as “MDU Resources,” the “Company,” “we,” “us,” or “our”) with respect to products that were manufactured, or contracted to be manufactured, during calendar year 2016 and that contain cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which are limited to tin, tantalum, and tungsten for purposes of this Report (collectively, the “Conflict Minerals”).

Third-party products that we sell but do not manufacture or contract to manufacture are outside the scope of this Report.

Company and Products Overview

MDU Resources is a regulated energy delivery and construction materials and services company which operates in a number of business segments, including electric, natural gas distribution, pipeline and midstream, construction materials and contracting, and construction services.

The Company, through its wholly-owned subsidiary MDU Construction Services Group, Inc., (“MDU Construction Services”) provides utility construction services specializing in constructing and maintaining electric and communication lines, gas pipelines, fire suppression systems, and external lighting and traffic signalization. MDU Construction Services also provides utility excavation and inside electrical and mechanical services, and manufactures and distributes

1



transmission line construction equipment and supplies. The construction equipment that is manufactured by MDU Construction Services, through its wholly-owned subsidiary Wagner-Smith Equipment Co., includes electric transmission line pullers, tensioners, reel stands, reel carriers, and electric transmission pole and material trailers (the “Construction Equipment”).

Based upon our internal assessment, certain of the Construction Equipment products are the only products that are either manufactured or contracted to be manufactured by the Company and its subsidiaries which contain Conflict Minerals. Accordingly, for purposes of this Report, only the Construction Equipment products were considered.

Supply Chain Overview

We have performed a detailed analysis of our Construction Equipment product components and the role that suppliers play throughout our manufacturing and product delivery processes. We do not purchase ore or unrefined Conflict Minerals directly from mines and we are many steps removed in the supply chain from the mining of the Conflict Minerals. Instead, the Company purchases materials used in our Construction Equipment from a large network of suppliers and some of those materials contribute necessary Conflict Minerals to certain of our products. The origin of the Conflict Minerals cannot be determined with any certainty once the raw ores are smelted, refined and converted to ingots, bullion or other Conflict Mineral containing derivatives. The smelters and refiners are the consolidating points for raw ore and are in the best position in the total supply chain to know the origins of the ores. We rely upon our suppliers to assist with our reasonable country of origin inquiry (“RCOI”) and due diligence efforts, including the identification of smelters and refiners in their respective supply chains, for the Conflict Minerals contained in the materials which they supply to us.

Conflict Minerals Program

Our Conflict Minerals program has been developed in conformity with the Organisation for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (Second Edition), and related Supplement on Tin, Tantalum and Tungsten and Supplement on Gold (collectively, the “OECD Guidance”), specifically as it relates to our position in the minerals supply chain as a “downstream” purchaser.

2



Our Conflict Minerals program includes components, summarized below, related to the five-step framework set forth in the OECD Guidance:

Management Systems

MDU Resources maintains an internal “Conflict Minerals” team which is responsible for implementing and overseeing our Conflict Minerals compliance strategy. Our team includes individuals from relevant function areas including accounting, legal, finance and operations.

     We maintain a Conflict Minerals Policy, available on our website, pursuant to which we:

1.
Work closely with our suppliers to determine the potential use of Conflict Minerals in our supply chain and, when appropriate, work with them to remediate issues and source more responsibly.

2.
Expect our Conflict Minerals suppliers to conduct the necessary inquiry and, where appropriate, additional due diligence to provide us with confirmation of the source of the materials used in their processes and ultimately present in our manufactured products; and

3.
Encourage our suppliers to advocate and adhere to our philosophy of sourcing Conflict Minerals from socially responsible suppliers, including conflict-free mines in the Democratic Republic of the Congo or adjoining countries (collectively, the “Covered Countries”).

Our employees, vendors, customers and other stakeholders may report any concerns relating to our Conflict Minerals program by telephone or online through our EthicsPoint system.

Identify and Assess Risks in Our Supply Chain

We have determined that seeking information about Conflict Minerals smelters and refiners in our supply chain from our suppliers represents the most reasonable effort we can make to determine the mines or location of origins of the Conflicts Minerals in our Construction Equipment. We

3



identify direct suppliers that supply products to us that may contain Conflict Minerals. We then survey those suppliers, requesting relevant information regarding the origins of Conflict Minerals used in the products they supply to us and the smelters and refiners used in connection with such Conflict Minerals. We follow up, by telephone and written correspondence, with those suppliers that do not respond by a specified date. We review the responses for completeness, request additional information as necessary, and request our suppliers to update the information provided as new information becomes available. We then compare the smelters and refiners identified in the supply chain survey against the list of facilities that have been designated “conflict-free” by the Conflict-Free Sourcing Initiative (“CFSI”) under its Conflict Free Smelter Program (the “CFSP”) and against the CFSI list of active facilities that have committed to undergo a CFSP audit. We rely on the CFSI to carry out smelter assessments and audits.

Design and Implement a Strategy to Respond to Risks

We encourage our suppliers to advocate and adhere to our philosophy of sourcing Conflict Minerals from socially responsible suppliers, including conflict-free mines, and support industry efforts to encourage smelters and refiners to seek “conflict-free” designation by the CFSI. We intend to work with suppliers who are sourcing minerals from non-conflict-free smelters and refiners to move towards using conflict-free facilities within a reasonable time frame. The time frame to work with suppliers on alternative sourcing will be dependent on the criticality of the specific part and the availability of alternative suppliers.

Risk management efforts are discussed by the Conflicts Mineral team and risk assessment updates are provided regularly to senior management.

Reasonable Country of Origin Inquiry

We have conducted a RCOI regarding the Conflict Minerals purchased by the Company that was reasonably designed to determine whether any such Conflict Minerals originated in the Covered Countries, or were from recycled or scrap sources. We identified 111 suppliers that provided components or engaged in manufacturing activities for use in our Construction Equipment products that may contain Conflict Minerals during calendar year 2016. In January 2017, we contacted these suppliers and provided them with a copy of our Conflict Minerals Policy, the CFSI Conflict Minerals Reporting Template (the “Template”) and an instructional letter to assist them in completing their responses. The Template includes questions regarding a supplier’s conflict-free policy, engagement with its direct suppliers, and a listing of the smelters and refiners the supplier and its suppliers use. In addition, the Template contains questions about the origin of Conflict Minerals included in the supplier’s products, as well as the supplier’s due diligence processes. We requested responses by April 1, 2017 and conducted follow-up by telephone and written correspondence with those suppliers that did not respond to the initial request.

Of the suppliers surveyed, 58% (64 suppliers) responded to our request for information. Based upon the results of our RCOI and due to numerous non-responsive suppliers, we cannot exclude the possibility that some of the Conflict Minerals used in our Construction Equipment products originated or may have originated in the Covered Countries and are not from recycled or scrap sources.

Design of Due Diligence

Our Conflict Minerals due diligence measures have been designed to conform to the due diligence-related steps of the OECD Guidance, as applicable for a “downstream” purchaser.

Due Diligence Measures Performed

Below is a description of the measures we performed to exercise due diligence on the source and chain of custody of the necessary Conflict Minerals contained in our Construction Equipment.


5



We sent our suppliers a letter which included the Template and instructions and requested that they complete and return the Template.
We requested that our suppliers adopt and communicate their Conflict Mineral policies and sourcing expectation to their suppliers and request that they complete the Template.
We followed up by telephone and written correspondence with our suppliers that failed to complete and return the Template and solicited additional information.
We reviewed all received supplier Templates for completeness. Suppliers that did not provide complete information or provided information that we identified as potentially inaccurate were requested to take corrective actions and update their Template responses.
We compared smelters identified in supplier Templates against the list of smelters that have committed to undergo a CFSP audit and the list of smelters that have received a “conflict free” designation under the CFSP.
    
Due Diligence Results

For reporting year 2016, we surveyed 111 suppliers of materials for our Construction Equipment using the Template. Of the suppliers surveyed, 58% (64 suppliers) responded to our request for information. We have relied on these suppliers' responses to provide us with information about the source of Conflict Minerals contained in the components supplied to us. Our direct suppliers are similarly reliant upon information provided by their suppliers.

As the result of our due diligence, we have gathered 644 smelter names from our supply chain. Of these, 246 have been designated as conflict-free compliant under the CFSP. An additional 13 are active facilities that have committed to undergo a CFSP audit. Of the remaining reported smelters, 359 have been determined to be legitimate processing facilities by the CFSI and have been allocated a Smelter Identification CID number. The final 26 are alleged smelters which have not yet been validated by CFSI.

We requested mine or location of origin information for the necessary Conflict Minerals from each of our suppliers using the Template. In some instances our suppliers reported name or location of mine. However, many of our suppliers were unable to obtain reliable mine or location of origin data for their necessary Conflict Minerals.


6



Two smelters, Phoenix Metal Ltd. and Universal Precious Metals Refining Zambia, were identified by some of our suppliers as having their location in a Covered Country. Neither smelter is currently listed as a compliant or active facility by the CFSI.

Determination

Many of our suppliers were unable to represent to us that the Conflict Minerals from the entities they listed had actually been included in materials they supplied to us. In addition, many processing facilities were not validated as in fact being smelters or refiners. Therefore, based on the information provided by our suppliers, we have elected to present only the facility names recognized by the CFSI on Annex 1 and believe that these facilities may have been used to process the Conflict Minerals in our Construction Equipment.

Based on our due diligence efforts, we do not have sufficient information to conclusively determine the countries of origin of the Conflict Minerals in our Construction Equipment or whether the Conflict Minerals are from recycled or scrap sources. On the basis of the due diligence measures described in this Report, we have reason to believe that some of the Conflict Minerals used in our Construction Equipment products may have originated in the Covered Countries and are not from recycled or scrap sources, but we have not identified any instances in which our sourcing of necessary Conflict Minerals directly or indirectly financed or benefitted armed groups in the Covered Countries.

We have provided information as of the date of this Report. Subsequent events may affect our future determinations under the Rule.

Future Due Diligence Measures

As we continue to enhance our due diligence program, we intend to take the following steps, among others, to continue to mitigate the risk that the necessary Conflict Minerals in our Construction Equipment could benefit armed groups in the Covered Countries:

Track and add new suppliers to our Conflict Minerals program as they enter our supply chain;


7



Drive our suppliers to obtain current, accurate and complete information about their smelters and refiners of Conflict Minerals;

Continue to identify additional smelters and refiners and encourage them to obtain “conflict-free” designation; and

Seek to obtain additional information about identified smelters and refiners not recognized by CFSI, for example by researching and reviewing news articles, facility websites or other public information, that may indicate where such smelters and refiners source their Conflict Minerals.
