a Rule 13p-1 under the Securities Exchange Act (17 CFR 240.13p-1) for the reporting period from January 1 to December 31, 2016.

Section 1 - Conflict Minerals Disclosure

Electro Scientific Industries, Inc., including its subsidiaries (ESI), is a leading supplier of innovative laser-based manufacturing solutions for the microtechnology industry. Our advanced laser systems enable precise structuring of micron to submicron features in components and devices which are used in a wide variety of end products in the consumer electronics, computer, semiconductor, communications and other markets. These features enable our customers to achieve functionality, or improve yield and productivity in their manufacturing processes that can be critical to their profitability. Founded in 1944, ESI is headquartered in Portland, Oregon, with global operations and subsidiaries in Asia, Canada, Europe and the United States.

ESI has evaluated its product lines for the year ending December 31, 2016 in accordance with Rule 13p-1 under the Securities Exchange Act of 1934 and the Security and Exchange Commission’s adopting release (collectively, the Rule), and in accordance with ESI’s Conflict Minerals Policy Statement. That statement is also publicly available on our website at http://investors.esi.com/governance.cfm.

After ESI reviewed its product lines to make an initial determination of whether it manufactured or contracted to manufacture products as to which “conflict minerals” (as defined in the Rule) were necessary for the functionality or production of the product, ESI conducted a “reasonable country of origin inquiry” (RCOI) consistent with the Rule. ESI’s RCOI employed a combination of measures to determine whether the necessary conflict minerals in its products originated from the Democratic Republic of the Congo and its adjoining countries (as defined in the Rule, Covered Countries). ESI’s primary means of determining country of origin of necessary conflict minerals was by conducting a supply-chain survey with direct suppliers using the EICC/GeSI Conflict Minerals Reporting Template. To identify and assess risk in the supply chain, ESI reviewed those suppliers who provide the substantial majority of our components and whose products the Company believes are likely to contain conflict minerals. The components provided by these suppliers represented approximately 80% of component costs incurred by the Company during 2016. ESI conducted a survey of suppliers to determine whether conflict minerals necessary to the functionality or production of components contained in our products were or were not sourced from the DRC or other Covered Countries (as defined in the Rule). We utilized a third-party service provider to administer components of this due diligence with appropriate oversight by ESI. Additionally, ESI used the Conflict Free Smelter Initiative (CFSI) website (http://www.conflictfreesourcing.org/), smelter company websites and other online tools to provide additional country of origin information.

ESI has concluded that during calendar 2016:

a. ESI has manufactured or contracted to manufacture products as to which conflict minerals are necessary to the functionality or production of ESI’s products.

b. Based on ESI’s RCOI, ESI knows or has reason to believe that a portion of its necessary conflict minerals originated or may have originated in a Covered Country, and is unable to determine that those necessary conflict minerals did not come from recycled or scrap sources.
