Section 1 – Conflict Minerals Disclosure

Item 1.01.

Conflict Minerals Disclosure and Report

Silgan Holdings Inc. (which may be referenced as "Silgan," "it," "we," "us" or "our") manufactures rigid packaging for consumer goods products. In accordance with Rule 13p-1 under the Securities Exchange Act of 1934, as amended, we conducted a reasonable country of origin inquiry ("RCOI") to assess whether "conflict minerals" (in the form of tin, tantalum, tungsten and gold) necessary to the functionality or production of products we manufactured or contracted to manufacture in 2017 originated in the Democratic Republic of the Congo or an adjoining country (collectively, the "Covered Countries"). In accordance with the rules of the Securities and Exchange Commission, our analysis and disclosure excludes product lines of the dispensing systems operations that we acquired from WestRock Company in April 2017.

Silgan's RCOI and Results

Silgan's product lines during 2017, except for product lines of the dispensing systems operations acquired in April 2017, were as follows:

·	Steel and aluminum containers for human and pet food and general line products;

·	Metal and plastic closures for food and beverage products, and capping/sealing equipment and detection systems; and

·	Custom design plastic containers for various consumer goods products.

Based on the results of our RCOI, we have reason to believe that some of the necessary conflict minerals contained in the electronic components of our capping/sealing equipment and detection systems product line for 2017 may have originated in the Covered Countries and may not be from recycled or scrap sources. Silgan was therefore required to conduct due diligence on the source and chain of custody of these conflict minerals and prepare a Conflict Minerals Report, filed as Exhibit 1.01 hereto.

A copy of the Conflict Minerals Report for the calendar year ended December 31, 2017 is filed as Exhibit 1.01 hereto and is also publicly available on our internet website at www.silganholdings.com/formsdandconflictmineralsreport.
