CATERPILLAR INC.
Conflict Minerals Report
For The Year Ended December 31, 2018
Section 1: Introduction and Company Overview
This Conflict Minerals Report (“CMR”) of Caterpillar Inc. (herein referred to as “Caterpillar,” “we,” or “our”) is
being filed in accordance with Rule 13p-1 under the Securities Exchange Act of 1934 (“Rule 13p-1”) for calendar
year 2018. Unless otherwise defined herein, terms used in this CMR are as defined in Rule 13p-1 and Form SD.
References to internet websites herein are provided only as required by Rule 13p-1 and information available
through these websites is not incorporated by reference into this Form SD. Statements in this CMR are based on ourdue diligence activities performed in good faith. Factors that could affect the accuracy of these statements include,
but are not limited to, incomplete supplier data, lack of available smelter and refiner data and errors or omissions bysuppliers or smelters.
With 2018 sales and revenues of $54.722 billion, Caterpillar is the world’s leading manufacturer of construction andmining equipment, diesel and natural gas engines, industrial gas turbines and diesel-electric locomotives. We
principally operate through our three primary segments - Construction Industries, Resource Industries and Energy
and Transportation - and also provide financing and related services through our Financial Products segment. We arealso a leading U.S. exporter. Through a global network of independent dealers and direct sales of certain products,
we build long-term relationships with customers around the world.
We manufacture and contract to manufacture products that contain tin, tantalum, tungsten and gold (“3TG”) which isnecessary to the functionality and/or production of such products (the “3TG Products”). For example, tin, tantalum,
tungsten and gold are each contained respectively in weld wire, capacitors, lamps and electrical connection coatings,
each of which are components in many of our 3TG Products. Our 3TG Products are listed on Schedule A attachedhereto. We have relationships with a vast network of suppliers worldwide and we rely on our suppliers to provide
information on the origin of the 3TG contained in the components and materials supplied to us. As a downstream
purchaser, Caterpillar, in most instances, is many steps removed from the smelters and refiners in our supply chain.
To the best of our knowledge, Caterpillar does not purchase 3TG directly from the Democratic Republic of theCongo or in any adjoining country (collectively, the “Covered Countries”). Because of Caterpillar’s size, thecomplexity of our products and the depth, breadth and constant evolution of our supply chain, it is difficult to
identify suppliers upstream from our direct suppliers. Accordingly, we participate in an industry-wide initiativedescribed in Section 4 below. Caterpillar is also an active participant in other industry associations that increaseawareness for responsible sourcing of conflict minerals and develop related resources that benefit the entire supply
chain.
Section 2: Reasonable Country of Origin Inquiry
Caterpillar’s method for determining the country of origin of 3TG contained in our 3TG Products is to conduct a
supply-chain survey with direct suppliers using the template developed by the Responsible Minerals Initiative(“RMI”) known as the Conflict Minerals Reporting Template (the “CMRT”). The CMRT was developed to facilitate
disclosure and communication of information regarding smelters and refiners that provide materials to a
manufacturer’s supply chain. The CMRT includes questions regarding a direct supplier’s conflict-free policy, its due
diligence process and information about its supply chain, including the names and locations of smelters and refiners
as well as the country of origin of 3TG used by those facilities.
We surveyed approximately 99% of our suppliers known or suspected to provide components and materials for our
3TG Products (“Impacted Suppliers”), which resulted in 18,716 inquiries. Some Impacted Suppliers received
multiple inquiries. While we requested that all Impacted Suppliers respond to the survey, we targeted “high-priority”
suppliers representing the top 80% of our expenditures for components and materials known or suspected to include
3TG. We have an internal escalation process for following up with unresponsive suppliers to increase the response

1rate with an emphasis on high-priority suppliers. For 2018, we received responses from 100% of these high-priority
suppliers equaling 848 total responses. Based on these results, we have a reason to believe that some of the 3TG in
our supply chain may have originated in the Covered Countries and also have reason to believe that such 3TG may
not be from recycled or scrap sources.
Section 3: Design of Due Diligence Framework
In accordance with Rule 13p-1, we undertook due diligence efforts on the source and chain of custody of 3TG in our
supply chain. Rule 13p-1 requires that a registrant’s due diligence follow a nationally or internationally recognized
due diligence framework. Presently, the only nationally or internationally recognized due diligence framework
available is the Organisation for Economic Co-operation and Development Due Diligence Guidance for Responsible
Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and related Supplements for each of theconflict minerals (the “OECD Guidance”). The OECD Guidance is a framework for risk-based due diligence forresponsible supply chains of conflict minerals from conflict-affected and high-risk areas that is described in the fivesteps noted in Section 4 below.
Caterpillar designed its due diligence measures to be in conformity, in all material respects, with the OECD
Guidance.
Section 4: Due Diligence Measures Performed
This Section 4 describes measures performed by us to exercise due diligence on the source and chain of custody of
3TG contained in our 3TG Products.
Step 1 - Establish Strong Company Management Systems
Conflict Minerals Position Statement
Caterpillar has posted on our website a position statement on conflict minerals which states our commitment to the
responsible sourcing of conflict minerals used in our products and that we will not knowingly provide support to,contribute to, assist with, or facilitate armed conflict in the Covered Countries. Our conflict minerals position
statement encourages suppliers to procure materials through conflict free sources and clarifies that we do not want toprevent suppliers from sourcing from legitimate mines located within the Covered Countries as doing so could be
detrimental to the local economies and populations. A copy of our conflict minerals position statement is publicly
available at http://www.caterpillar.com/en/company/sustainability/conflict-minerals.html.
Systems of Controls and Transparency
We rely on our suppliers to provide information on the origin of the 3TG contained in the components and materials
supplied to us. Caterpillar is a member of the RMI (Member ID: CATE), an initiative developed to identify anddisclose upstream actors in the supply chain, including 3TG smelters and refiners, to determine red flag locations of
3TG origin in the supply chain. RMI program initiatives include the Responsible Minerals Assurance Process(“RMAP”) which identifies smelters and refiners that process materials from conflict-free sources, and the CMRT
which is a free, standardized reporting template that facilitates the transfer of information through the supply chain
regarding the country of origin of 3TG and smelters and refiners being utilized.
We sent correspondence to smelters and refiners not currently participating in the RMAP where the RMI had contact
information for such smelters and refiners, to encourage them to participate in the RMAP. In the event we establish
chain of custody to a non-conformant smelter or refiner, we developed an escalation process to notify the applicabledirect suppliers to encourage the smelter or refiner to participate in RMAP. We also sent correspondence tosmelters and refiners identified by our suppliers in response to our supply-chain survey that were validated asconformant under the RMAP as of May 3, 2019 thanking them for their participation in the RMAP. Throughmembership in RMI, Caterpillar participated in working groups such as the RMI Multi-Stakeholder Group, Smelter

2

Engagement Team, Due Diligence Practices Team, CMRT Team and Plenary Team to support in-region efforts andbolster supply chain transparency.
We retain records relating to our conflict minerals compliance program for a period of 5 years.
Internal Management Systems
We established a management system to manage our conflict minerals compliance program through a group of
cross-functional senior leaders that are responsible for the oversight of our conflict minerals compliance program,which includes officer-level personnel. In addition, a project team with senior-level managers is responsible for thedevelopment and deployment of our conflict minerals compliance program.
Supplier Engagement
As stated in our conflict minerals position statement, our strategy is to establish long-term relationships andcollaborate with our suppliers. To communicate our expectations relating to responsible sourcing of conflictminerals, Caterpillar posted on our website our position statement on conflict minerals referenced above. We
developed and made available a web-based training presentation to suppliers on topics including the requirements ofRule 13p-1, Caterpillar’s obligations under Rule 13p-1 and instructions for responding to the CMRT. The language
in our standard purchase order terms and conditions requires our suppliers to provide us with supporting informationand documentation evidencing due diligence of 3TG in their respective supply chains upon our request for suchinformation.
Company Level Grievance Mechanism
Caterpillar’s Worldwide Code of Conduct is called “Our Values in Action.” Our Values in Action articulates ourlong-standing support for, and commitment to, human rights and the dignity of all people. Caterpillar has a humanrights policy that articulates our commitment to respect internationally recognized human rights and complements
Our Values in Action. Our Values in Action requires employees to report any circumstance or action that violates, orappears to violate, Our Values in Action, enterprise policy or applicable law, and we maintain methods for
employees and other interested parties to confidentially report such circumstances or actions.
Step 2 - Identify and Assess Risks in the Supply Chain
Our method for determining the country of origin of 3TG contained in our 3TG Products was to conduct a supplychain survey with Impacted Suppliers using the CMRT.
We reviewed Impacted Supplier responses against criteria developed by our internal team to determine whether
further engagement was necessary. Smelters and refiners identified by a supplier in response to our supply-chain
survey are also compared against the list of facilities that have received a conformant or active designation by the
RMAP which provides country of origin and due diligence information on the conflict minerals sources by such
facilities. As part of our efforts to track and investigate facilities in our supply chain that may be sourcing 3TG fromthe Covered Countries, we provided to the RMI for investigation a list of smelters and refiners identified in supplier
responses to our supply-chain survey that were unknown to the RMAP.
Step 3 - Design and Implement a Strategy to Respond to Identified Risks
We have a process that outlines our response to risks identified in our supply chain. Members of our senior
management are apprised of the status of our conflict minerals compliance program, which includes actual andpotential risks and red flags identified in our supply chain relating to conflict minerals. The executive officer signing
this Form SD is briefed on our conflict minerals compliance program, including our supply-chain survey, the designof our due diligence framework, the due diligence measures we performed and the corresponding results.

As part of our process and to assist our Impacted Suppliers in understanding our expectations, we request our
Impacted Suppliers that do not respond to the supply-chain survey referenced above or that provide incomplete orinconsistent responses to the survey to complete a training program. We have established a process that identifies
areas of risk on an ongoing basis and corrective action plans to mitigate or remediate such risks relating to conflictminerals. A supplier’s failure to take corrective actions when required may lead to additional actions, up to andincluding the termination of our business relationship.
Step 4 - Carry Out Independent Third Party Audit of Smelter/Refiner’s Due Diligence Practices
We support audits of 3TG smelters and refiners through our participation in, and financial support of, the RMAP.
We do not perform direct audits of these entities within our supply network. To enhance our understanding of
responsible sourcing, a Caterpillar representative attended a pre-audit visit to a tin smelter that was organized by
RMI members in April 2018.
Step 5 - Report Annually on Supply Chain Due Diligence
We are filing this CMR with the Securities and Exchange Commission, which is also publicly available on our
website at http://www.caterpillar.com//en/company/sustainability/conflict-minerals/CMR.html.
Section 5: Due Diligence Results
We rely on our suppliers to provide information on the origin of 3TG contained in the components and materials
supplied to us. These suppliers are similarly reliant upon information provided by their suppliers. The responses we
received from Impacted Suppliers in the supply-chain survey collectively identified 265 unique facilities identified
by RMAP of which 256 or approximately 97% were validated as conformant under the RMAP as of April 24, 2019.
Based on the information provided by Impacted Suppliers in the supply-chain survey and the due diligence measuresdescribed above, we have reason to believe that tin or tantalum was sourced from a total of five suppliers for use inparts and components supplied to Caterpillar from the smelters listed on Schedule B attached hereto. Furthermore,
based on the information obtained as a result of the due diligence measures described above, we reasonably
determined that the minerals processed by these smelters may be from the countries of origin listed on Schedule Cattached hereto. Each of these smelters was validated as conformant under the RMAP.
With regard to the other responses to our supply-chain survey that identified specific smelters or refiners, to theextent they were valid smelters and refiners, we cannot be certain that the identified smelters and refiners supplied
3TG for parts and components supplied to Caterpillar rather than to other customers. For this reason, with the
exception of the tin and tantalum suppliers noted above, we have been unable to establish chain of custody or
identify with confidence the specific facilities used to process the 3TG in our 3TG Products, the country of origin or
the mine or location of origin of the 3TG in our 3TG Products.
Section 6: Efforts to Determine the Mine or Location of Origin
Caterpillar’s efforts to determine the mines or locations of origin of the 3TG in our supply chain include providing
financial and in-kind support to the RMI, continued implementation of the due diligence measures described above,
including conducting surveys of our Impacted Suppliers utilizing the CMRT.
Section 7: Steps to be Taken to Mitigate Risk
Caterpillar intends to take the following steps to improve our due diligence process, including:•Continue to engage suppliers by providing them with training resources in connection with our supplychain survey to attempt to increase supplier response rates overall, improve the content of supplier
responses and reduce the number of non-responsive suppliers;

4•Continue to require suppliers in new or renewed contracts to provide information about the source of 3TG
contained in components and materials supplied to us;•

Continue to work with the RMI to expand the smelters and refiners participating in the RMAP; and•Continue to encourage suppliers that manufacture components or materials containing 3TG to source themfrom validated smelters when sufficient options exist for procuring conflict-free materials.
