To confirm the origin, the Company identified its tin supplier and conducted in good faith a reasonable country of origin inquiry that was reasonably designed to determine whether any tin supplied to the Company by its supplier originated in the DRC Countries. The Company's tin supplier completed the Conflict Minerals Reporting Template (&#x201c;CMRT&#x201d;) developed by the Conflict-Free Sourcing Initiative (&#34;CFSI&#34;). The CMRT is designed to confirm the use of Conflict Minerals, identify the source of the Conflict Minerals, and determine whether any of the Conflict Minerals originated in the DRC Countries or were from recycled or scrap sources.</font></p>

Based on the completed CMRT returned by our supplier and our reasonable country of origin inquiry described above, the Company has determined for the year ended December 31, 2023 that the Conflict Minerals necessary to the functionality or production of the Company&#x2019;s products did not originate in any of the DRC Countries.</font><font style="color:#000000;white-space:pre-wrap;font-size:10pt;font-family:Times New Roman;min-width:fit-content;"> </font></p>
