provide information regarding the smelters or refiners of the Conflict Minerals in their components. Other suppliers identified certain of the smelters and refiners they used, but the suppliers provided company-wide, aggregate smelter information
across all of their products, rather than specific information regarding the smelters or refiners of the Conflict Minerals in the specific components used in our products. As a result, we are not able at this time to identify the smelters or

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In order to identify and assess risk in our supply chain, we hired Silicon Expert as a third-party service provider to conduct a supply-chain
survey with direct suppliers using the Conflict Minerals Reporting Template from RMI. Silicon Expert asked suppliers to determine if Conflict Minerals were necessary to the functionality of their products provided to Teradyne and, if yes, to provide
information regarding the smelters/refiners for the Conflict Minerals included in those products. Silicon Experts sent surveys to 155 direct suppliers. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Silicon Expert reviewed the supplier responses for completeness and consistency based on our internally defined review criteria and followed
up with suppliers to obtain additional information or clarification. We prioritized our efforts based on the amount of spending with a supplier. Silicon Expert received responses from 133 suppliers representing
<FONT STYLE="white-space:nowrap">Eighty-six</FONT> percent (86%) of the suppliers to whom they sent surveys and approximately&nbsp;ninety percent 90% of our annual spending. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Silicon Expert asked suppliers who indicated they use Conflict Minerals in their products to provide a list of their smelters/refiners. The
responses provided aggregate information across all their products, rather than specific information regarding the smelters or refiners of the Conflict Minerals in the specific components used in our products. As a result, we are not able at this
time to identify the smelters or refiners of the Conflict Minerals in the particular components used in our products. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">From the
suppliers&#146; responses, we attempted to identify the smelters/refiners used in our suppliers&#146; supply chain. Silicon Expert compared the names of smelters/refiners identified by our suppliers against the Standard Smelter List maintained by
RMI. In many cases, Silicon Expert were unable to match the names provided with the names in the list and could not otherwise verify whether many named smelters/refiners were active businesses with smelting/refining operations. Through this process,
Silicon Expert identified unique smelters/refiners used by the responding suppliers that were on RMI&#146;s Standard Smelter List. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Silicon Expert have not independently investigated the smelters/refiners identified by our suppliers but are relying on the RMI who is taking

the Conflict Minerals used in our products originate from the Covered Countries and are not sourced from smelters/refiners on RMI&#146;s Conflict Free Smelter List. We designed and implemented a strategy to mitigate these identified risks, as
discussed above, even though we have not identified any known instances where the Conflict Minerals used in our products directly or indirectly financed or benefit armed groups in the Covered Countries. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The internal team responsible for our Conflict Minerals program has reported to senior management the results of the Company&#146;s reasonable
