Exhibit 1.01

MTS Systems Corporation

Conflict Minerals Report

Introduction

This Conflict Minerals Report (the “Report”) of MTS Systems Corporation (the “Company” or “MTS”) has been prepared pursuant to Rule 13p-1 and Form SD promulgated under the Securities Exchange Act of 1934, as amended (the “Rule”), for the reporting period from January 1, 2019 to December 31, 2019.

The Rule requires disclosure of the use of certain minerals, namely, gold, columbite-tantalite (coltan), cassiterite and wolframite, including their derivatives, which are limited to tantalum, tin and tungsten (collectively referred to herein as the “conflict minerals”) that are necessary to the functionality or production of products that MTS manufactures or contracts to manufacture.

The objective of the Rule is to have manufacturers of products that may contain conflict minerals disclose the source of these conflict minerals. To furnish the requirements of the Rule, manufacturers have to determine whether the conflict minerals in their products originate from and are being used to support armed conflict in the Democratic Republic of the Congo and adjoining countries (collectively referred to herein as “covered countries”). The “covered countries” for the purposes of this Report are the Democratic Republic of Congo, the Republic of the Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola.

As described in this Report, MTS manufactures products for which the conflict minerals are necessary to the functionality or production of those products.

Company Overview

MTS’ Test & Simulation segment provides testing and simulation hardware, software and service solutions that simulate real word environments in other than real world settings thereby enabling our customers to improve design, development and manufacturing processes, determine the mechanical behavior of materials, products and structures, or create a desired human experience such as amusement rides, vehicle simulators or flight training simulators. MTS’ Sensors segment produces high-performance sensors which provide measurements of vibration, pressure, position, force and sound in a variety of applications.

Products Overview

This Report relates to products: (i) for which the conflict minerals are necessary to the functionality or production of that product; (ii) that were manufactured by MTS; and (iii) for which the manufacture was completed during calendar year 2019. These products, which are referred to in this Report collectively as the “covered products” are the following: test and simulation equipment and systems for the ground vehicles, materials and structures markets in addition to high-performance sensors for a variety of position, test and industrial applications.

Due Diligence Design and Framework

Based on the results of the good faith reasonable country of origin inquiry (“RCOI”) described in the Form SD to which this Report is filed as an exhibit, MTS has exercised due diligence on the source and chain of custody of conflict minerals contained in its covered products. MTS has designed its due diligence measures to conform, in all material respects, with the internationally recognized due diligence framework as set forth in the Organization for Economic Cooperation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (OECD, 2013) (“OECD Framework”) and related supplements for gold and for tin, tantalum and tungsten.

Step 1. Established company management systems:

• Policy: MTS has a “Conflict Minerals Policy” (the “MTS policy”) that is published on its website at: http://www.mts.com/cs/groups/public/documents/corporatedocuments/mts_007983.pdf

• Supplier Terms and Conditions: MTS includes conflict minerals related terms and conditions in purchase orders entered into with its suppliers related to each supplier’s agreement to reviewing and complying with MTS policy.

• Applicability Assessment: MTS engages with suppliers that may be supplying products containing conflict minerals.

MTS conducted an applicability assessment to determine in-scope suppliers. In-scope suppliers were determined to be suppliers with the potential of manufacturing goods sold to MTS containing conflict minerals.

In-scope suppliers for the Test & Simulation segment were identified using the North American Industry Classification System (NAICS) codes. NAICS codes are standardized codes for groups of vendors with similar economic activity or production. For the Sensors segment, in-scope suppliers were identified according to their manufacturing profile which included specific information on the types of materials they supply to MTS. Suppliers for both segments that were either non-manufacturing or supplying material that did not contain any conflict minerals were segmented out of the in-scope supplier list.

Once all in-scope suppliers were aggregated, another filter was applied using dollar spend. Suppliers that represented 95% of the total related dollar spend for conflict minerals were selected for survey.

From this 95% listing, suppliers who responded consistently for the prior two years that the material supplied to MTS did not contain conflict minerals were not selected for the RCOI / Due Diligence phase.

The final aggregated supplier lists for the Test & Simulation and Sensors segments as discussed above were used to conduct the RCOI / Due Diligence phase.

• RCOI / Due Diligence: MTS’ RCOI and due diligence measures focus on working with its suppliers based upon a framework established by the Responsible Mineral Initiative (“RMI”) to identify the location of smelters and refiners of conflict minerals provided to its suppliers. MTS conducted supply chain surveys based on the RMI conflict minerals questionnaire with all applicable suppliers identified during its applicability assessment explained above.

Step 2. Identify and assess risks in the supply chain:

• Smelters and Refiners: Suppliers surveyed were asked to identify smelters or refiners (“SORs”) that processed conflict minerals contained in MTS’s products, including country of origin of any conflict minerals, based on the RMI conflict minerals questionnaire.

• Survey Results: A third-party vendor logged surveys into their technology platform and reviewed each survey for complete and accurate smelter list and conflict mineral sourcing information.

Non-responsive suppliers and survey responses that were incomplete or inconsistent were identified for additional follow-up.

Additional reasons for follow-up with suppliers included, but were not limited to, suppliers providing an incomplete or inaccurate smelter list or incomplete conflict mineral sourcing information related to their relevant suppliers. This also included suppliers that did not provide the country of origin information in their survey responses.

• Responsible Mineral Initiative Smelter Database: Smelters identified by MTS’ suppliers were compared against the lists maintained by RMI and the smelter list prepared by the third-party vendor.

Step 3. Design and implement a strategy to respond to identified risks:

• Non-Conformant Smelters: Suppliers that responded with smelters not listed as conformant or active on the lists prepared by RMI were engaged to validate sourcing from these smelters for products supplied to MTS.

• Public Domain Search: The third-party vendor conducted research in the public domain in order to identify sourcing information for smelters that were not on the RMI compliant smelter list, when possible.

• Sourcing Practice Communication: MTS communicated to suppliers about sourcing practices that did not conform to MTS policy, and noted that non-conformance could result in removal of the supplier from the supply chain if these efforts to remove high risk smelters were not taken.

Business Unit representatives also notified suppliers to ensure that applicable suppliers updated their responses with accurate and complete information.

Step 4. Carry out independent third-party audit of smelters / refiners due diligence practices

• MTS is a downstream consumer of conflict minerals and is many steps removed from smelters and refiners who source raw minerals and ores. MTS does not purchase raw minerals or ores, and does not, to the best of its knowledge, directly purchase conflict minerals from any of the covered countries.

Step 5. Report annually on supply chain due diligence

• This Report, and the associated Form SD, are available online at the following website:

https://www.mts.com/corpdocs/ESGPoliciesPractices.pdf

Due Diligence Measures Undertaken

In accordance with the OECD Framework, MTS took the following measures during the reporting year to exercise due diligence on the source and chain of custody of conflict minerals:

• Third-Party Vendor: A third-party provider was engaged by MTS to survey applicable suppliers and review supplier responses received to determine completeness, accuracy and consistency of information submitted.

• Supplier Re-engagement: Suppliers that did not send a complete or accurate response or a response consistent with MTS policy were re-engaged to update their responses.

• RMI Smelter Database: MTS utilized the RMI smelter database and other proprietary resources to determine the sourcing locations for the SORs identified in MTS’ supply chain.

• Supplier Follow-Up: MTS re-engaged suppliers to request that sourcing be changed from SORs that are known to source from covered countries or were not validated by RMI to be conflict free.

Results

Based on the RCOI and after exercising the due diligence described above, MTS knows or has reason to believe that a portion of its necessary conflict minerals originated or may have originated in the covered countries and knows or has reason to believe that those necessary conflict minerals may not be solely from recycled or scrap sources. In addition, MTS identified that some conflict minerals may have originated in a covered country and MTS has insufficient country of origin information from suppliers or other sources regarding all of the smelters that processed these minerals.

MTS received representations from 81% of its in-scope suppliers. Of the smelter information received from its suppliers, approximately 79% have been designated as conflict free or actively pursuing such designation under the

RMI (list of these smelters is provided in Annex 1). The remaining smelters identified as potentially sourcing conflict minerals are not currently RMI compliant or actively pursuing such designation. The source of conflict minerals from these smelters is undetermined at this time. MTS has taken and will continue to take actions to mitigate risk regarding conflict minerals used in its products as noted in the “Continuous Efforts to Mitigate Risk” section of this Report.

Independent Audit

An independent private sector audit of this Report is not required.

Continuous Efforts to Mitigate Risk

MTS has taken and will continue efforts to improve its conflict minerals risk assessment and survey process in the future reporting periods. MTS will continue to mitigate risk that the conflict minerals used in its products may finance or benefit armed groups in the covered countries by:

• Encouraging suppliers to source from smelters that have received the conflict free designation or that are otherwise subject to adequate due diligence to ensure such minerals are not being used to fund conflict.

• Continuing to work with suppliers to identify, to the extent possible, the source of conflict minerals used in MTS’ products.

• Continuing to use contract terms and conditions for new contracts requiring suppliers to respond to inquiries regarding conflict minerals in a timely manner.

Certain statements in this Report may be “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include expectations concerning MTS’ future actions to engage suppliers, to identify to the extent possible the source of conflict minerals in its products and to take other actions regarding its product sourcing. MTS’ actual actions or results may differ materially from those expected or anticipated in the forward-looking statements due to both known and unknown risks and uncertainties including, but not limited to, decisions to make changes in MTS’ continual improvement efforts and delays or difficulties in engaging suppliers and identifying the source of conflict minerals contained in MTS’ products.
