Section 1 — Conflict Minerals Disclosure
Item 1.01. Conflict Minerals Disclosure and Report
Ribbon Communications Inc. (the
“Company” or “Ribbon”) has determined that some of the products that it manufactured or contracted to manufacture
through the end of reporting year 2023 (“Ribbon Products”), include gold, columbite-tantalite (coltan), cassiterite and wolframite,
including their derivatives, tantalum, tin and tungsten (collectively, “Conflict Minerals”). The Company has further determined
that these Conflict Minerals are necessary to the functionality or production of the Ribbon Products.

Products originated in the Covered Countries and are not from recycled or scrap sources. The Company therefore engaged in due diligence
on the source and chain of custody of the Conflict Minerals in the Ribbon Products that originated or may have originated in the Covered
Countries, as described in its Conflict Minerals Report filed herewith as Exhibit 1.01, and available on the Investor Relations —
Corporate Governance section of the Company’s website at http://investors.ribboncommunications.com/governance.cfm.

Introduction
This report for the year ended December 31, 2023
has been prepared by Ribbon Communications
Inc. (the “Company”, “Ribbon”, “we,” “us,” or “our”)
to comply with Rule 13p-1 (the “Rule”) under the
Securities Exchange Act of 1934, as amended.
The Rule imposes certain disclosure and reporting
obligations on companies that report with the
SEC and which manufacture, or contract to have
manufactured, products containing conflict
minerals that are necessary to the functionality or
production of those products. Conflict Minerals
are defined as cassiterite, columbite-tantalite, gold,
wolframite, and their derivatives, which are limited
to tin, tantalum, tungsten, and gold (collectively,
“Conflict Minerals”).
Ribbon has determined that some of the products
that it manufactured or contracted to manufacture,
and which continue to be manufactured or
contracted to manufacture by Ribbon through the
end of reporting year 2023 (“Ribbon Products”)
include Conflict Minerals.

Conflict Minerals Policy
Ribbon has adopted a Conflict Minerals
Policy and communicated such policy to its
suppliers. This policy is available on the Investor
Relations-Corporate Governance section of
the Company’s website at https://investors.
ribboncommunications.com/static-files/79ec23fd-657e-4d9b-8d90-5e2daec9c183.
Products Overview
This report covers the following Ribbon Products
that were manufactured in 2023 (the “2023 Ribbon
Products”): SBCs, DSCs, Voice over IP (VoIP)
trunking solutions, policy/routing servers, media
and signaling gateways, including the GSX 9000
High-Density Media Gateway, IP Optical Solutions,
IP Routing Solutions and network analytics tools.
Supply Chain and
Reasonable Country of
Origin Inquiry
Ribbon has determined that Conflict Minerals
are necessary to the functionality or production
of Ribbon Products manufactured or contracted
to be manufactured during 2023. We utilize an
outsourced supply chain model pursuant to which
our contract manufacturers procure materials on
our behalf. Our supply chain is multi-tiered, global
and complex, and we outsource the manufacturing
of our hardware products such that we are many
steps removed from the mining and smelting or
refining of Conflict Minerals. Therefore, we rely
upon our suppliers to provide information on the
origin, source and chain of custody of the Conflict
Minerals contained in product components
and materials. Some of these suppliers may
themselves purchase from lower tier suppliers and
not directly from a miner, smelter or refiner.
The Company conducted a Reasonable Country of
Origin Inquiry (“RCOI”) to determine whether any of
the Conflict Minerals in our 2023 Ribbon Products
originated in the Democratic Republic of the
Congo (“DRC”) or an adjoining country (collectively,
the “Covered Countries”) and whether the Conflict
Minerals are from recycled or scrap sources.
Based on our RCOI, we know or have reason to
believe that some of the Conflict Minerals in our
2023 Ribbon Products originated in the Covered
Countries and are not from recycled or scrap
sources.
Ribbon’s RCOI measures included conducting
a supply-chain survey with in-scope suppliers
using the Responsible Minerals Initiative (“RMI”)
Reporting Template (the “Template”). The
Template was developed to facilitate disclosure
and communication of information regarding
smelters that provide material to a company’s
supply chain. It includes questions regarding the
supplier’s conflict-free policy, engagement with
its direct suppliers, and a listing of the smelters
the company and its suppliers use. In addition,
the Template contains questions about the origin
of Conflict Minerals included in the company’s
products, as well as supplier due diligence. The
Template was designed to provide companies with
sufficient information regarding their suppliers’
practices with respect to the sourcing of Conflict
Minerals to enable such companies to comply with
the requirements of the Rule.
Due Diligence Process
In accordance with the Rule, Ribbon undertook due
diligence on the source and chain of custody of
the Conflict Minerals in the 2023 Ribbon Products
that originated or may have originated in the
Covered Countries. The Company’s due diligence
measures were designed to conform, in all
material respects, to the internationally recognized |
| Ribbon Communications Inc. Conflict Minerals Report 2023 6
due diligence framework in The Organization for
Economic Co-operation and Development (“OECD”)
Due Diligence Guidance for Responsible Supply
Chains of Minerals from Conflict-Affected and
High-Risk Areas (“OECD Guidance”) and the related
supplements.
Due Diligence Measures
Ribbon performed the following due diligence
measures in accordance with the OECD Guidance
and the Rule:
OECD Guidance Step 1: Establish Strong
Company Management Systems
Ribbon’s Conflict Minerals compliance efforts
are overseen by the Company’s Vice President,
Manufacturing, Operations and Supply Chain
and its manufacturing department, and
supported and sponsored by the Company’s
engineering, audit and legal departments.
Ribbon employees who are responsible for
Conflict Minerals compliance have received
training regarding Conflict Minerals compliance.
The team was structured to ensure critical
information, including our policies related to this
subject matter, reached relevant employees and
suppliers. To the extent red flags or other issues
are identified in the supplier data acquisition or
engagement processes, these issues and red
flags will be addressed first by the responsible
individuals within the engineering, audit and legal
departments, and, if deemed necessary, will
then be reported to and reviewed by the Audit
Committee (the “Audit Committee”) of the Board
of Directors at regularly schedule meetings on
an annual basis.
Ribbon also engaged SiliconExpert
Technologies, a provider of electronic
component data and BOM Management
software to the electronics industry
(“SiliconExpert”), to assist with its Conflict
Minerals compliance efforts. Frequent status
meetings are held between Ribbon’s Conflict
Minerals support team and SiliconExpert, with
Ribbon management receiving status updates
on progress and due diligence efforts on a
regular and timely basis.
In addition, Ribbon has a Conflict Minerals Policy
and communicates such policy to its suppliers,
which is available on our Investor Relations —
Corporate Governance section of our website
at https://investors.ribboncommunications.
com/static-files/79ec23fd-657e-4d9b-8d90-
5e2daec9c183.
To the extent any employee, officer or director
has concerns or grievances about the
Company’s potential use of Conflict Minerals,
such individual is urged to contact his or her
manager, the Company’s Chief Financial Officer,
the Chief Legal Officer or other member of
senior management, the Employee Hotline
(which can be used on an anonymous basis
where permitted by applicable law) or the Audit
Committee.
Ribbon established documentation and
record maintenance mechanisms to ensure
the retention of information relevant to
the Company’s Conflict Minerals Policy
electronically.
OECD Guidance Step 2: Identify and
Assess Risk in the Supply Chain
Ribbon reviewed the information reported on the
Template by its suppliers and followed up with
any additional questions. To the extent an in-scope supplier had follow-up questions, Ribbon
responded with all requested information,
including part numbers and manufacturing lots
to identify how the supplies were used in the
Ribbon Products. |
| Ribbon Communications Inc. Conflict Minerals Report 2023 7
Untimely or incomplete responses as well
as inconsistencies within the data reported
by suppliers were addressed directly with
respective suppliers to provide the required and/
or revised responses. Ribbon utilizes a series of
escalating responses to address the failure of a
supplier to provide the information required by
the Template.
Ribbon’s engineering, audit and legal
departments manage the collection of
information reported on the Template by its
suppliers.
Ribbon collected a list of smelters/processors
that are in our supply chain for the Ribbon
Products using the Template and reconciled this
list to the list of smelter facilities designated by
the Responsible Minerals Assurance Process
(“RMAP”). Ribbon has provided that list in this
report.
Ribbon, through SiliconExpert, followed up with
suppliers that did not respond initially to our
requests to complete the Template.
OECD Guidance Step 3: Design and
Implement a Strategy to Respond to
Identified Risks
Ribbon adopted and used the Template to
monitor and mitigate supply chain risk and took
the steps described above.
Ribbon worked with certain suppliers to better
educate them on the Conflict Minerals process.
Members of the Conflict Minerals team
periodically report to senior management
as well as the Audit Committee on program
developments and progress.
OECD Guidance Step 4: Carry Out
Independent Third-Party Audit of Supply
Chain Due Diligence
Given that we do not generally have a direct
relationship with the smelters and refineries that
process the Conflict Minerals that are present
in our Ribbon Products, we rely on the RMI to
conduct audits of and validate the conflict-free
status of smelters and refineries that source
from Covered Countries. We have not relied on
supplier representations concerning the conflict
status of their smelters, but have required
industry certification such as through the RMAP
before concluding that a smelter or refinery is
conflict free. We understand that this program
is continuing to audit smelters and refineries to
add to its Conflict-Free Smelter List.
OECD Guidance Step 5: Report on Supply
Chain Due Diligence
As required by the Rule, we have filed a Form
SD and a Conflict Minerals Report as an exhibit
thereto for the 2023 calendar year reporting
period. In accordance with OECD Guidance and
the Rule, this report is available on our Investor
Relations-Corporate Governance section of our
website at:
https://investors.ribboncommunications.com/

| Ribbon Communications Inc. Conflict Minerals Report 2023 8
Due Diligence Results
Ribbon contacted 100% of a total of 852 in-scope
suppliers (excluding distributors and service
providers) for the 2023 Ribbon Products.
Total in-scope suppliers contacted 852
Manufacturers providing CMRT
documents/data 669
Manufacturers not providing CMRT
responses
183
Overall response rate 78.5%
The majority of the completed responses received
provided conflict mineral data and a declaration at
a “Company Level” (supplier/company declaration
represents all the supplier’s products) or “Divisional
Level” (supplier/company declaration represents
all the supplier’s products from a division of the
company). As a result, we are unable to determine
whether any of the Conflict Minerals reported
by the suppliers were contained in specific
components or parts supplied to us with regard to
Ribbon Products.
Further, while our suppliers for the Ribbon
Products identified certain of the smelters and
refineries that provided Conflict Minerals, the
responses did not provide specific information
regarding the smelters or refineries of the Conflict
Minerals in the particular components used in the
2023 Ribbon Products. Based on the responses
we received from our suppliers, however, we
believe the facilities used to produce the Conflict
Minerals in the 2023 Ribbon Products may include
the smelters and refineries listed in Annex A. In
addition, based on the supplier responses, we
believe the countries of origin of the Conflict
Minerals in the 2023 Ribbon Products may include
those listed in Annex B.
79% of in-scope suppliers provided
responses to the CMRT survey. |

Over the years, Ribbon has increased the pool of
in-scope suppliers as business has expanded.
Ribbon’s ability to secure responses from a greater
number of suppliers is the result of consistent
efforts to reach out to suppliers to educate
them on the importance of conflict minerals
management and secure full responses to our
CMRT requests.

Based on the responses we received from our
suppliers, however, we believe the facilities used to
produce the Conflict Minerals in the 2023 Ribbon
Products may include the smelters and refineries
listed in Annex A.
In 2023, we were successful in maintaining a
strong response rate of 79%, a little higher than in
2022, representing a 7% increase in the number of
suppliers responding, alongside a 6% increase in
the number of suppliers we contacted.
In addition, based on the supplier responses,
we believe the countries of origin of the Conflict
Minerals in the 2023 Ribbon Products may include
those listed in Annex B.
In 2023, the total number of in-scope manufacturers
responding to Ribbon’s CMRT request was more than
660 manufacturers, a response rate of more than
78%, for the third consecutive year.

Risk Mitigation Steps to
Be Taken for 2024 Due
Diligence
Ribbon intends to take the following steps, as
appropriate, during the next compliance period
to further improve our due diligence process and
results and to further mitigate the risk that our
necessary Conflict Minerals benefit armed groups
in the DRC or adjoining countries:
Continue to focus on additional ways to improve
quality and quantity of supplier response rates;
Continue to work with suppliers to better
educate them on the process;
Continue to compare survey results to
information collected via independent conflict
free smelter validation programs such as the
RMAP;
Seek to implement standard procedures for
corrective action or phasing out of suppliers not
found to be DRC conflict free;
Continue to adhere to the OECD Guidance; and
Seek to work with suppliers who use appropriate
due diligence methods and have continuous
monitoring of both the direct and indirect supply
chain to avoid procurement or use of Conflict
Minerals.
