Our Conflict Minerals Program is designed to conduct a Reasonable Country of Origin Inquiry (a &#x201c;RCOI&#x201d;) regarding conflict minerals that are used in the parts and components that we procure as well as the smelters and refiners used to provide those minerals. In accordance with the Conflict Minerals Rule, our RCOI process was designed to include 100% of the components and materials for which conflict minerals are necessary to the functionality or production of a product manufactured, or contracted to be manufactured, by ADTRAN during the year ended December 31, 2023.</font></p>

As ADTRAN does not source conflict minerals directly from smelters or refiners, our process leverages the CMRT. ADTRAN received responses accounting for 75% of our total annual spend in parts and components that we procure. After receiving all CMRTs, we utilized the Responsible Minerals Initiative (the &#x201c;RMI&#x201d;) Smelter/Refiner List to validate all smelters.</font><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:Times New Roman;min-width:fit-content;"> </font></p>

Corrective actions are identified as applicable and suppliers are required to resubmit the CMRT for future evaluation. For those suppliers that have provided smelters or refiners that are not certified conflict free, the conflict minerals team continually assesses the risk level associated with each supplier and reports those findings to management.

In addition to our RCOI due diligence described above, we have conducted further diligence with our suppliers who have identified smelters and refiners that may have processed conflict minerals as reflected in the table below. Due to our position in the supply chain, we rely on our suppliers for accurate smelter and refinery information and consequently, our due diligence measures do not provide absolute certainty regarding the source of the necessary conflict minerals contained in the scope of products we manufacture.</font><font style="color:#000000;white-space:pre-wrap;font-size:11pt;font-family:Times New Roman;min-width:fit-content;"> </font></p>

However, not all of the included smelters and refiners are believed by us to have processed the conflict minerals contained in the products that we manufactured. Many of the suppliers report to us the conflict minerals contained in all of their products, not just those in the products sold to ADTRAN. Some suppliers may have also reported to us smelters and refiners that were not in our supply chain due to over-inclusiveness in the information received from their suppliers or for other reasons. In addition, the smelters and refiners reflected above may not be all of the smelters and refiners in our supply chain, since some suppliers were unable to identify all of the smelters and refiners used to process the necessary conflict minerals content contained in the products that they manufactured and not all of the suppliers responded to our inquiries. The smelter/refinery status and origin reflected in the table is based solely on information made available by the RMAP. All compliance status information in the table is as of May 21, 2024.</font></p>

Origin information was derived from information made available through the Conflict &#x2013;Free Smelter Program. According to this information, some of the compliant smelters and refiners may have sourced from both within the DRC Region and from outside the DRC Region. For these smelters and refiners, we were not able to determine the country of origin of the conflict minerals specific to our products. Therefore, not all of the country of origin information reflected in the table may apply to the necessary conflict minerals contained in the products that we manufactured. If a smelter or refiner sourced from multiple sources, it is included in the table under each applicable category.</font></div></div>
