West Pharmaceutical Services, Inc.

Conflict Minerals Report

For the Year Ended December 31, 2015

Company Overview

This Conflict Minerals Report (the “Report”) of West Pharmaceutical Services, Inc. (the “Company”) has been prepared pursuant to Rule 13p-1 (the “Rule”) and Form SD promulgated under the Securities Exchange Act of 1934 for the period from January 1, 2015 to December 31, 2015. Unless the context indicates otherwise, “West,” “we,” “us,” and “our” refer to West Pharmaceutical Services, Inc. and its subsidiaries.

West Pharmaceutical Services, Inc. is a manufacturer of components and systems for the packaging and delivery of injectable drugs as well as components for the pharmaceutical, healthcare and consumer products industries. Our products include stoppers and seals for vials, prefillable syringe components and systems, components for intravenous and blood collection systems, safety and administration systems, advanced injection systems, and contract design and manufacturing services.

Supply Chain

In 2015, West operated through two business segments, Pharmaceutical Delivery Systems ("PDS") and Pharmaceutical Packaging Systems ("PPS"). PDS was the only segment that sourced columbite-tantalite (coltan), cassiterite, gold, wolframite or their derivatives (tantalum, tin and tungsten) (“3TGs”) that are necessary to the functionality or production of its products (“Covered Products”). PPS did not produce any Covered Products. PDS developed, manufactured and sold our portfolio of proprietary technologies that included prefilled syringes with automatic needle retraction, drug reconstitution delivery systems, auto-injectors and wearable injectors. The PDS segment had manufacturing operations in North America and Europe.

Beginning in 2016, we changed our organization and reporting structure for our next phase of growth and development, which resulted in a change to Proprietary Products and Contract-Manufactured Products as our reportable segments. Please refer to the Quarterly Report on Form 10-Q for the quarter ended March 31, 2016 for additional information.

As a downstream company, West purchases the materials and components for the products that we manufacture from third parties. We do not have direct relationships with smelters or refiners that produce the 3TGs within our supply chain and do not control any mineral reserves. Thus, any 3TGs that are potentially present in any of our products would have originated solely from our purchases from third parties.

Conflict Minerals Program

West is committed to working with our global supply chain to ensure compliance with the Rule. We have established a conflict minerals compliance program that is designed to follow the framework established by the Organization for Economic Cooperation and Development (“OECD”), as tailored for downstream companies.

Our compliance program endeavors to identify whether the 3TGs in the Covered Products originated in the Democratic Republic of the Congo or an adjoining country (the Republic of the Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia or Angola) (“Covered Countries”), or whether any of the 3TGs in the Covered Products were from recycled or scrap sources. In 2015, our Conflict Minerals Steering Committee, consisting of Procurement, Legal, Regulatory and Compliance, oversaw enhancements to our due diligence on the origination of the 3TGs in our Covered Products. In an effort to mitigate the risk going forward, we increased the number of resources dedicated to this effort, included West’s position statement relating to conflict minerals in our Business Partner Code of Conduct, available here, and included language related to conflict minerals in new supply agreements and questionnaires. Our conflict minerals compliance program is implemented by our procurement group and senior management is informed periodically of the progress.

Description of West’s Reasonable Country of Origin Inquiry

We conducted a reasonable country of origin inquiry (“RCOI”) that was reasonably designed to determine in good faith whether any of the 3TGs in the Covered Products originated in the Covered Countries or were from recycled or scrap sources.

In conducting our RCOI, we employed a three-step approach. First, we identified direct suppliers of materials that contain 3TGs necessary to the functionality or production of the West product (in other words, whether the products were Covered Products, as defined above). Second, we conducted a supply chain survey of these suppliers to obtain information on the origin of 3TGs contained in the materials supplied to us. Third, we evaluated the adequacy of the responses and continued to investigate to determine whether any of the 3TGs in our covered products originated in the covered countries.

The supply chain survey was implemented and administered by our procurement group. The survey employed the template developed by the Electronic Industry Citizenship Coalition^® and the Global e-Sustainability Initiative, known as the Conflict-Free Sourcing Initiative (“CFSI”) Reporting Template (the “Survey”). The Survey requested general disclosures, the identification of any 3TGs contained in the supplier’s products and the origin of those minerals. We have received information from at least 95% of the suppliers we surveyed, although not all of the information requested was provided.

Due Diligence Process

Following our RCOI, we conducted a due diligence review of the source and chain of custody of the 3TGs contained in the Covered Products. Our due diligence measures were designed to conform in all material respects with the framework in the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (“OECD Guidance”) and the related supplements for 3TGs.

As part of this due diligence, we implemented management systems to identify and reduce risk in our supply chain regarding conflict minerals. Our management systems include enhanced communication with our suppliers, improved tracking mechanisms and increased employee education. These systems are designed to ensure the supply chain survey reached all relevant suppliers and adequate responses were received. We evaluated the responses against criteria designed to identify those suppliers that warrant further investigation, including for example, untimely, inconsistent or incomplete responses, requests for confidentiality, missing or erroneous data, whether the supplier was a U.S. publicly-held company, the size of the supplier’s business and the material supplied to us. As appropriate, we followed up directly with suppliers whose answers required it to obtain additional information and updated responses.

As a downstream purchaser of 3TGs, or components containing 3TGs, our diligence procedures can provide only reasonable, not absolute, assurance regarding the source and chain of custody of such materials. Our diligence processes are based on the necessity of seeking data from our direct suppliers and those suppliers seeking similar information within their supply chains to identify the original sources of 3TGs. We also rely, to a large extent, on information collected and provided by third parties. Such sources of information may yield inaccurate or incomplete information and may be subject to fraud.

Conclusion

Our Covered Products are subject to the reporting obligations of the Rule. After having conducted a good faith reasonable country of origin inquiry and due diligence, we have concluded that our Covered Products contain 3TGs that are necessary to their functionality or production, and based on the information provided to us by the majority of our suppliers, either (a) the sources of the 3TGs contained in the Covered Products are certified compliant by CFSI or (b) the 3TGs contained in the Covered Products are not sourced from the Covered Countries. Despite our efforts, we did not receive adequate responses from a small percentage of our suppliers to determine the country of origin (or recycled or scrap status) of all of the 3TGs in our supply chain.

Based on the responses that we received from our suppliers, we identified 545 smelters and refineries as potential sources of 3TGs reported to be in our supply chain, of which 214 have been verified by the CFSI to be conflict free and 43 are in the process of being verified. Table 1 below presents, by mineral, the total number of smelters and refineries identified and the percentage verified to be conflict free or in the CFSI Verification Process. See Appendix 1 for a list of smelters and refiners by name verified as conflict free.

Table 1. Smelters or refiners verified as conflict free or in the verification process

Tantalum	47 of 58 (81%)
Tin	75 of 204 (37%)
Tungsten	42 of 61 (69%)
Gold	93 of 222 (42%)
Total	257 of 545 (47%)

Risk Mitigation

We have taken the following steps to further mitigate the risk that the 3TGs in the Covered Products could benefit armed groups in the Covered Countries by:

• Enhancing our supplier screening program to require new suppliers, suppliers to recently acquired businesses and suppliers of new products or components to provide information regarding 3TGs. The Company also intends to provide additional background and educational information for suppliers where necessary to facilitate obtaining responses. Finally, the Company will augment disclosure clauses regarding 3TGs in new supply contracts and supplier contract renewals.

• Continuing the activities of our Conflict Minerals Steering Committee to: (i) ensure the management systems are adequate; (ii) review the RCOI and due diligence progress; (iii) discuss what actions West should take to mitigate risk; and (iv) report the status of West’s Conflict Mineral program to senior management periodically.

• Engaging in efforts with our suppliers to educate them on the importance of the 3TGs due diligence process and our expectations; and further improving our direct supplier surveys and due diligence process.
