Conflict Minerals Report

for the Year Ended December 31, 2022

Introduction

Viavi Solutions Inc. (“VIAVI,” also referred to as “the Company,” “we,” “our,” and “us”) is a global provider of network test, monitoring and assurance solutions for communications service providers, hyperscalers, equipment manufacturers, enterprises, government and avionics. VIAVI is also a leader in light management technologies for 3D sensing, anti-counterfeiting, consumer electronics, industrial, automotive, government and aerospace applications. Together with our customers and partners we are United in Possibility, finding innovative ways to solve real-world problems.

This Conflict Minerals Report (“CMR”) for the year ended December 31, 2022, is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (the “Rule”). The Rule imposes certain reporting obligations on U.S. Securities and Exchange Commission (“SEC”) issuers whose manufactured products contain certain minerals that are necessary to the functionality or production of their products. These minerals are cassiterite, columbite- tantalite (coltan), gold, wolframite, and their derivatives, which are limited to tin, tantalum and tungsten (“3TG” or Conflict Minerals”). The Rule focuses on 3TG originating from the Democratic Republic of Congo (“DRC”) or an adjoining country (together, the “Covered Countries”). If an issuer has reason to believe that any of the Conflict Minerals in their supply chain may have originated in the Covered Countries, or if they are unable to determine the country of origin of those Conflict Minerals, then the issuer must exercise due diligence on the Conflict Minerals’ source and chain of custody and submit a CMR to the SEC that includes a description of those due diligence measures.

This CMR relates to the process undertaken for VIAVI products that were manufactured, or contracted to be manufactured, during calendar year 2022 and that contain Conflict Minerals.

Executive Summary

We performed a Reasonable Country of Origin Inquiry (“RCOI”) on suppliers we believe provided materials or components containing 3TGs necessary to the manufacturing of our products during calendar year 2022. Our suppliers identified 348 valid smelters and refineries (“Smelters”). Of these 348 Smelters, we identified 47 as sourcing (or there was a reason to believe they may be sourcing) from the Covered Countries. Our due diligence review indicated that 35 of these Smelters have been audited and recognized as conformant with Responsible Minerals Assurance Process (“RMAP”) standards. The remaining 12 Smelters potentially sourcing from the Covered Countries were subject to our risk mitigation process, which is conducted in accordance with the OECD Due Diligence Guidance for Responsible Supply Chain of Minerals from Conflict-Affected and High-Risk Areas and the supplements thereto (the “OECD Guidance”).

Company Management Systems

VIAVI established strong management systems based on Step 1 of the OECD Guidance.

•Step 1A - Adopt, and clearly communicate to suppliers and the public, a company policy for the supply chain of minerals originating from conflict-affected and high-risk areas. We adopted a policy that is publicly available at https://www.viavisolutions.com/en-us/corporate/legal/compliance . This policy is communicated directly to our suppliers as part of the RCOI process.

•Step 1B - Structure internal management to support supply chain due diligence. We maintain a cross- functional internal team to support our supply chain due diligence efforts. This team reports its findings to a senior member of the supply chain managementorganization.

•Step 1C - Establish a system of controls and transparency over the supply chain. We implemented a detailed process to collect required supplier and smelter RCOI and due diligence data. Full details on the supply chain data gathering are included in the RCOI and due diligence sections of this Report.

•Step 1D - Strengthen company engagement with suppliers. We engage with contract manufacturers and suppliers during theRCOIprocess.Additionally,oursuppliertermsandconditionsrequiresupplierstosourcematerials from smelters that, if sourcing from conflict-affected or high-risk areas, are either conformant with RMAP standards or are working towards conformance. Working with our contract manufacturers, we monitor the quantity and quality of supplier and smelter responses year-over-year.

•Step 1E - Establish a company-level grievance mechanism. Our employees and suppliers can anonymously report a violation of our policies through our ethics hotline. We also maintain the e-mail address conflictminerals@viavisolutions.com for suppliers and employees to report violations, ask questions and voice concerns regarding Conflict Minerals sourcing.

Reasonable Country of Origin Inquiry (RCOI)

We designed our RCOI process in accordance with Step 2 of the OECD Guidance. Our RCOI process involved two stages:

•Stage 1 - Supplier RCOI (Step 2A of the OECDGuidance)

•Stage 2 - Smelter RCOI (Step 2B of the OECD Guidance)

For the 2022 reporting period, VIAVI’s RCOI process was executed by a third-party vendor.

Supplier RCOI

We designed our supplier RCOI process to identify the smelters in our supply chain. Our supplier RCOI process for the 2022 reporting period included:

•developing a list of suppliers providing 3TG containing components;

•contacting each supplier and requesting Conflict Minerals data using the RMI’s Conflict Minerals Reporting Template(“CMRT”)

•reviewing supplier responses for accuracy and completeness;

•aggregating supplier-provided smelters into a single unique list of smelters meeting the definition of a smelter under one of three industry-recognized audit protocols; and

•reviewing the final smelter list (and comparing it to the lists of industry peers) for completeness.

Through the supplier RCOI process we identified 348 Smelters in our supply chain (178 gold smelters, 35 tantalum smelters, 82 tin smelters, and 53 tungsten smelters).

Smelter RCOI

Due to the overlap between smelter RCOI and smelter due diligence, the smelter RCOI process is summarized in the due diligence section of this report.

Due Diligence

For the 2022 reporting period, VIAVI’s smelter due diligence process was executed by a third-party vendor.

Smelter RCOI and Due Diligence

We engaged with each smelter identified in our supply chain to determine whether or not they sourced from the Covered Countries. For smelters that confirmed, either directly or through industry associations, that they did not source from the Covered Countries but that were not identified by the RMI as conformant with RMAP standards, we reviewed publicly available information to determine whether there was any information that contradicted the smelter’s declaration. In doing so, we reviewed sources such as NGO publications, including publications by the Enough Project, Global Witness, Southern Africa Resource Watch and Radio Okapi. We also consulted the most recent United Nations Group of Experts reports on the DRC and performed public internet searches.

If smelters did not respond to our inquiry, we reviewed the same publicly available sources to determine whether there was reason to believe the smelter may have sourced from the Covered Countries during the reporting period.

We categorize smelters that are sourcing (or that we have reason to believe may be sourcing) from the Covered Countries as high-risk. We require that all high-risk smelters be audited and recognized as conformant with RMAP standards or be working towards such designation. If any high-risk smelters are not recognized as conformant with RMAP standards, we conduct the risk mitigation procedures described below.

Our suppliers identified 348 unique smelters, of which 47 smelters source, or there is a reason to believe they may source, from the Covered Countries. We determined that 35 of these 47 smelters have been recognized as conformant with RMAP standards. We conducted risk mitigation on the remaining 12 smelters.

Risk Mitigation

VIAVI conducted risk mitigation on 12 Smelters that were not recognized as conformant with RMAP standards and were sourcing (or there is a reason to believe they may be sourcing) from the Covered Countries. These 12 Smelters are all gold refiners located in the United Arab Emirates, Belgium, Sudan, Zimbabwe, Uganda, India, and Mauritania. VIAVI’s risk mitigation was designed in accordance with Step 3 of the OECD Guidance and was reported to the VP of Supply Chain Management.

As part of our risk mitigation process, we performed additional due diligence to determine if there was any reason to believe the smelter directly or indirectly financed or benefited armed groups in the Covered Countries. We also attempted to verify with internal stakeholders and relevant suppliers whether 3TG from the smelter in question was actually in any of VIAVI’s in-scope products. Finally, if necessary and where possible, we engaged directly with the smelter to encourage them to become recognized as conformant with RMAP standards.

We did not require the removal of smelters if there was no reason to believe they were directly or indirectly financing or benefiting armed groups in the Covered Countries. These smelters are scheduled to be re-visited in the 2023 reporting period.

Steps to Mitigate Risk

To attempt to mitigate the risk that the 3TG in our products could directly or indirectly benefit or finance armed groups in the Covered Countries, we are continuing to engage with and educate our suppliers to increase supplier response rates and improve the timeliness, accuracy and comprehensiveness of the supplier survey responses we receive. We are also continuing to work with our suppliers to encourage them to source from RMAP conformant smelters when sourcing material from the Covered Countries. Finally, we are attempting to engage with smelters sourcing from the Covered Countries to encourage them to become audited to a protocol recognized by the RMAP. Further, we are an affiliate of the Responsible Business Alliance (RBA), have endorsed the RBA Code of Conduct and expect our suppliers to adhere to it.

Smelters and Refineries

Forty-seven of the 348 unique Smelters identified during our RCOI either declared that they were sourcing, or there was reason to believe were sourcing, from the Covered Countries. Based on the Smelters’ disclosures and the publicly available information, we have reason to believe these Smelters may be sourcing from the following Covered Countries: the DRC, Rwanda, Burundi, Uganda, and Tanzania. Our due diligence review indicated that 35 of the 47 Smelters have been audited and recognized as conformant with RMAP standards.
