Exhibit 1.01

Conflict Minerals Report

Calix, Inc.

For the Year Ended December 31, 2019

This Conflict Minerals Report (“CMR”) is provided to comply with Rule 13p-1 of the Securities Exchange Act of 1934, as amended, for Calix, Inc. (“Calix”) for the calendar year ended December 31, 2019. Rule 13p-1, as implemented by the Securities and Exchange Commission (“SEC”), imposes reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Rule 13p-1 applies to SEC registrants whose manufactured products contain conflict minerals which are necessary to the functionality or production of their products, other than conflict minerals sourced solely from recycled or scrap sources. Conflict minerals are defined as cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which are limited to tin, tantalum, tungsten and gold, referred to as the 3TG.

If a registrant has reason to believe that any of the conflict minerals in their supply chain may have originated in the Democratic Republic of the Congo (“DRC”) or an adjoining country (together with the DRC, the “Covered Countries”), or a registrant is unable to determine the country of origin of those conflict minerals, then the registrant must exercise due diligence on the source and chain of custody of those conflict minerals.

Overview

Calix is a leading global provider of cloud and software platforms, systems and services required to deliver the unified access network and smart home and business services of tomorrow. Calix’s cloud and software platforms, systems and services enable communication service providers (“CSPs”) to provide a wide range of revenue-generating services, from basic voice and data to advanced broadband services, over legacy and next-generation access networks. Calix focuses on CSP access networks, the portion of the network that governs available bandwidth and determines the range and quality of services that can be offered to subscribers. Calix primarily relies upon third-party manufacturing partners to manufacture its products, purchase components or materials that may contain smelted or refined minerals and purchase raw ore or minerals. Calix is several levels removed from the purchase of raw ore and minerals or the mining of conflict minerals which occurs much further upstream in the supply chain.

For purposes of Rule 13p-1, we worked with our third-party manufacturing partners to conduct surveys of suppliers on our behalf and to make inquiries regarding suppliers further upstream in order to ascertain information on the origin of the conflict minerals in components and materials in our products. We rely upon third-party manufacturing partners, consisting of contract manufacturers and original design manufacturers, to source for and produce our products based on Calix-specified requirements, and in some cases Calix does not control the supplier sourcing decision. In selecting manufacturing partners, we require partners to regularly engage with and assess their supplier base as relevant to the components and materials for Calix products.

Based on evaluations together with our manufacturing partners for 2019, we identified that some components and materials that are included in Calix access systems contain conflict minerals.

Reasonable Country of Origin Inquiry

In order to perform a reasonable country of origin inquiry, or RCOI, we worked with our third-party manufacturers to conduct surveys of their direct supplier base to determine whether the conflict minerals contained in components of Calix products originated from the Covered Countries. This survey was conducted using the Conflict Minerals Reporting Template (“CMRT”) developed by the Responsible Minerals Initiative (“RMI”), and included inquiries related to the facilities used to process conflict minerals, a supplier’s commitment and processes to support conflict free sourcing and the smelters and refiners used, including a supplier’s further inquiries made upstream in the supply chain to ascertain such information. The survey was used to collect information to facilitate our understanding of the

1

country of origin of conflict minerals and information on the conflict free status for smelters and refiners used by the supplier or its upstream suppliers.

For 2019, surveys were distributed primarily through our third-party manufacturing partners to approximately 470 suppliers with a reported response rate of greater than 90% for completed surveys. To support improved response rate and quality of the CMRT process, personnel that have oversight responsibilities for conflict minerals within our manufacturing partner organizations review the CMRT responses and engage with our manufacturing partners to conduct follow-up inquiries for CMRT completeness and accuracy. Information regarding the RMI is included in surveys sent to the supplier base and manufacturing partners generally provide information and training to assist suppliers with completing the CMRT.

Based on the RCOI described above, we have reason to believe that some of the components used in the manufacture of our products in 2019 contained conflict minerals that originated from the Covered Countries and were not sourced solely from recycled or scrap sources.

Supply Chain Due Diligence and Assessment

Based on the RCOI on our supply chain and as required by Rule 13p-1, we undertook due diligence on our supply chain. The objective of this due diligence was to ascertain whether the conflict minerals directly or indirectly financed or benefited arms groups in the Covered Countries, including for the smelters identified through the CMRTs as providing conflict minerals that originated from the Covered Countries.

Based on our RCOI for 2019, there were approximately 76 smelters and refiners that were identified by suppliers as a source of conflict minerals originating from the Covered Countries. We conducted further due diligence on our supply chain primarily through our third-party manufacturing partners to assess, on our behalf, the source and chain of custody of the conflict minerals applying due diligence measures designed to conform with the Organization for Economic Co-operation and Development Due Diligence Guidelines for Responsible Supply Chains of Minerals from High Risk Areas and related supplements. These further actions included:

•Collection of conflict minerals information from the supply chain utilizing the CMRT

•Reviews of supplier, smelter and refiner information in CMRT responses for plausibility, consistency and completeness

•Supplier trainings on conflict minerals disclosures to facilitate accurate completion of the CMRT

•Follow-up efforts with suppliers for information about identified smelters and refiners

•Engagement with suppliers for further conflict minerals reporting upstream through the supply chain

•Review whether identified smelters and refiners, including those identified as a source of conflict minerals originating from the Covered Countries, are listed as participating in the Responsible Minerals Assurance Process (“RMAP”) operated by the RMI or otherwise verified as conflict free by industry recognized programs

•Conduct supplier outreach as recommended and in support of RMI initiatives, particularly for non-responding suppliers

Based on the due diligence conducted, we determined that 75 of the smelters and refiners identified to supply conflict minerals originating in the Covered Countries are included on the RMI list of conformant smelters and refiners pursuant to the RMAP program operated by the RMI. One non-RMI conformant smelter identified by our suppliers as supplying conflict minerals originating in the Covered Countries was removed by the RMI in August 2019. We intend to work with our suppliers to monitor further sourcing from this non-RMI conformant smelter. Based on the information provided by our suppliers, we believe that the facilities that may have been used to process the 3TG minerals in our products include the smelters and refiners listed in Appendix I to this CMR. Pursuant to Rule 13p-1, this CMR is not subject to an independent private sector audit.

Ongoing Risk Management

We intend to continue our work with our manufacturing partners to improve response rates to our conflict minerals surveys, including through direct and indirect outreach efforts to suppliers, and to improve awareness upstream in

2

the supply chain. We also expect to further refine conflict minerals assessments and inquiries as part of our supplier and manufacturer partner evaluation processes. This CMR is also available on Calix’s Investor Relations website at: https://investor-relations.calix.com under Governance – Governance Documents.
