Conflict Minerals Report

Calendar Year Ending December 31, 2015

May 31, 2016

Introduction

Pursuant to Section 13(p) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and related rules and guidance promulgated by the Securities and Exchange Commission (the “SEC”), including the SEC’s Statement dated April 29, 2014 (the “Conflict Minerals Rule”), if columbite-tantalite (tantalum), casserite (tin), gold or wolframite (tungsten) (“conflict minerals” or “3TG”) are necessary to the functionality or production of a product manufactured by a registrant or contracted by the registrant to be manufactured, the registrant must conduct in good faith a reasonable country of origin inquiry regarding those conflict minerals that is reasonably designed to determine whether any of the conflict minerals originated in the Democratic Republic of the Congo or an adjoining country (the “Covered Countries”).

This Conflict Minerals Report (this “Report”) (1) describes the reasonable country of origin inquiry
(“RCOI”) and subsequent due diligence efforts undertaken by Teledyne Technologies Incorporated (the “Company”) to determine whether in the 2015 calendar year the conflict minerals necessary to the functionality or production of a product manufactured by the Company or contracted by the Company to be manufactured originated in the Covered Countries and (2) provides additional disclosure required by the Conflict Minerals Rule.

Company Overview

The Company provides enabling technologies for industrial growth markets. The Company has evolved from a company that was primarily focused on aerospace and defense to one that serves multiple markets that require advanced technology and high reliability. These markets include deepwater oil and gas exploration and production, oceanographic research, air and water quality environmental monitoring, electronics design and development, factory automation and medical imaging. The Company’s products include monitoring and control instrumentation for marine and environmental applications, harsh environment interconnects, electronic test and measurement equipment, digital imaging sensors and cameras, aircraft information management systems, and
defense electronics and satellite communication subsystems. The Company also supplies engineered systems for defense, space, environmental and energy applications.

Conflict Minerals Policy

As part of the Company’s due diligence efforts, the Company has adopted a statement on Conflict Minerals which is available at: http://www.teledyne.com/aboutus/ethics.asp

Reasonable Country of Origin Inquiry (RCOI)

After the reasonable country of origin inquiry the Company had reason to believe that its necessary conflict minerals may have originated in the Covered Countries and had reason to believe that they may not be from recycled or scrap sources. In accordance with the Conflict Minerals Rule, the Company conducted due diligence on the source and chain of custody of those conflict minerals. The due diligence approach followed by the Company is intended to meet the criteria set forth 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, an internationally recognized due diligence framework, and the related Supplements for gold, tin, tantalum and tungsten (the “OECD Guidance”).

Description of the RCOI

Due to the wide variety and high mix of products manufactured and sold by the Company, the Company conducted its due diligence with its direct suppliers. In determining which suppliers to survey in 2015, the Company focused on suppliers of materials, parts and components. The Company identified 4,137 suppliers that in the aggregate were responsible for the top 80% of the total annual spending on materials, parts and components at each of the Company’s business units in the fiscal year ended December 28, 2014 (each such supplier an “In-Scope Supplier”). In-Scope Suppliers also included those suppliers that did not fall within the top 80% of a business unit’s annual spend, but which were known by the business unit with reasonably certainty to provide materials, parts or
components that contain Conflict Minerals.

The Company, with the assistance of Assent Compliance (“Assent”), attempted to contact all of the In-Scope Suppliers and provide each with a copy of the Company’s Statement on Conflict Minerals, a Conflict Minerals Reporting Template version 4.01 (“CMRT”) and instructions on how to complete the CMRT. The CMRT is a standardized reporting template developed by the Conflict-Free Sourcing Initiative (“CFSI”) that facilitates the transfer of information through the supply chain regarding mineral country of origin and smelters and refiners (“SORs”) being utilized. In-Scope Suppliers were instructed to return a completed CMRT to the Company within a certain time period after receipt.

Assent contacted non-responsive suppliers by email a minimum of three times and then by phone a
minimum of two to three times. Communications include training and education on the completion of the CMRT form as well as access to a Supplier Resource Center designed to alleviate any remaining confusion with suppliers. All communications were monitored and tracked in Assent's system for future reporting and transparency.

Teledyne’s Conflict Minerals program includes automated data validation on all submitted CMRTs. The goal of data validation is to increase the accuracy of submissions and identify any contradictory answers in the CMRT. All submitted CMRT forms are accepted and classified as valid or invalid so that data is still retained. Suppliers are contacted in regards to invalid forms and are encouraged to resubmit a valid form.

On the basis of the responses to the Company’s RCOI, the Company is unable to determine that 3TGs
necessary to the functionality or production of the Company’s products did not originate in the DRC or any of the Covered Countries. Accordingly, the Company undertook the measures described below to assess the due diligence practices of the SORs listed on its unique smelter list that were known or reasonably believed to have sourced from the DRC or that had unknown sourcing.

Design of Due Diligence Measures

Due Diligence Process

The Company established a Conflict Minerals compliance program that is designed to conform, in all
material respects, to the framework in the OECD Guidance.

1 Establish Strong Company Management System Internal Team

1.1 Adopt and commit to a supply chain plan for minerals originating from conflict-affected and high risk areas

In 2013, the Company adopted an internal Conflict Minerals Assessment Plan (the “Assessment Plan”) incorporating many of the standards set forth in the then current version of the OECD Guidance.

1.2 Structure internal management systems to support supply chain due diligence

The Company has established a management system with respect to the Rule and the obligations thereof. The Company’s management system includes a cross-functional team, the Conflict Minerals Team, which is sponsored by a Conflict Minerals Governance Committee consisting of the Company’s Senior Vice President and General Counsel, the Company’s Chief Operating Officer, and the Company’s Senior Vice President and Chief Financial Officer.. The Conflict Minerals Team is responsible for implementing the Company’s conflict minerals compliance program and is led by the Associate General Counsel who acts as the conflict minerals coordinator. The Conflict Minerals Governance Committee is briefed about the results of the Conflict Minerals Team’s progress and
due diligence efforts on a periodic basis.

1.3 Establish a system of controls and transparency over the mineral supply chain

While a portion of the Company’s direct suppliers are also Exchange Act reporting companies which are subject to and knowledgeable about the Conflict Minerals Rule, the Company also has many other suppliers and distributors that are not Exchange Act reporting companies that require additional training to understand the requirements of the Conflict Minerals Rule.

Internal controls include the Company’s on-going initiative of integrating conflict minerals related
requirements in its supply agreements that require disclosure of 3TGsconflict minerals.

The Company developed a record retention requirement for information relating to the management of its conflict minerals compliance process. All relevant records will be retained for a period of 5 years. In addition, Assent retains all information gathered during the supply survey portion of the Company’s conflict minerals program for the same 5 year period.

1.4 Strengthen company engagement with suppliers

With respect to the OECD requirement to strengthen engagement with suppliers, the Company has utilized the CMRT version 4.01 and the Assent Compliance Manager web-based reporting tool for collecting conflict minerals declarations from the Company’s supplier base. The use of these tools has allowed the Company to assist its suppliers in understanding the Company’s expectations and requirements and increase the rate of responses the Company has received from its suppliers to the Company’s survey requests.

Additionally, as identified earlier, the Company’s procurement organization continues to integrate contract provisions related to conflict minerals disclosure requirements language into new supply agreements or renewals of existing supply agreements during the course of negotiations. Accordingly, the Company is continuing its attempts to confirm suppliers have implemented processes to identify the origin of 3TGs.

1.5 Establish a company level grievance mechanism

The Company has established a confidential Corporate Ethics/Help Line, with the theme, "Take The Right Action." The Ethics/Help line is available to all Company employees, as well as concerned individuals outside the company. Violations of Company policies, including those related to conflict minerals, may be reported via this Ethics/HelpLine. The toll free help line number is 1-877-666-6968.

2 Identify and assess risk in the supply chain

In accordance with OECD Guidelines, it is important to understand risk levels associated with conflict minerals in the supply chain. Smelters that are not certified as DRC-Conflict Free by third party sources such as the CFSI or the London Bullion Market Association (“LBMA”) Responsible Gold Programme, pose a significant risk. Assent rates the risk of SORs as High, Medium or Low. This rating is based on various factors, including whether the SOR has been certified conflict free, has committed to a third-party audit, and the smelter’s geographic location, including proximity to the Covered Countries.

Assent verified, to the best of its knowledge, whether the metals processors identified by each supplier on its CMRT are actually SORs or recyclers of 3TGs by comparing facilities reported by suppliers to the CFSI Standard Smelter List and conducting its own independent research. If an SOR was not certified by an internationally-recognized scheme, Assent attempted to contact the SOR to gather more information about its sourcing practices. In addition, internet research was performed to determine whether there was any publicly available sources of information regarding the SOR’s sourcing.

Assent calculates supplier risk based on the chances that a supplier provides 3TGs that may originate from Non-Conflict Free sources. The value of this risk is calculated based on the risk ratings of the smelters declared by that Supplier on their CMRT.

Additionally, suppliers are evaluated on program strength (further assisting in identifying risk in the supply chain). Evaluating and tracking the strength of the program can assist in making key risk mitigation decisions as the program progresses. The criteria used to evaluate the strength of the supplier’s program are:
• Does the supplier have a policy in place that includes DRC conflict-free sourcing?
• Has the supplier implemented due diligence measures for conflict-free sourcing?
• Does the supplier verify due diligence information received from its suppliers?
• Does the supplier verification process include corrective action management?

Based on a supplier’s answers to these criteria, the supplier’s program is deemed to be either strong or weak.

As part of the Company’s Assessment Plan and to ensure suppliers understand the Company’s expectations, Assent provides video and written training on conflict minerals and the CMRT. This includes instructions on completing the form, and one-on-one email and phone discussions with supplier personnel.

Tracing materials back to their mine of origin is a complex aspect of responsible sourcing in the Company’s supply chain. The Company determined that seeking information about 3TG smelters and refiners in its supply chain represents the most reasonable effort the Company can make to determine the mines or locations of origin of the 3TGs in its supply chain. This was done by adopting methodology outlined by the EICC and programs and outreach initiatives and requiring the Company’s suppliers to report to the Company using the CMRT. Through this industry joint effort, the Company made reasonable determination of the mines or locations of origin of the 3TGs in
its supply chain.

3. Design and implement a strategy to respond to identified risks

The Company has developed and continues to use a risk management approach to implement due diligence activities concerning 3TGs and the potential presence of conflict minerals.

The Company’s current strategy to respond to supply chain risks, as described in the Company’s
Assessment Plan, is that if the Company become aware of a supplier whose supply chain includes 3TGs that are not conflict free, the Company will take appropriate steps to address the situation in a timely manner, including supplier education and/or reassessment of the supplier relationship. To date, the Company has found no instances where it was necessary to terminate a contract or find a replacement material or supplier.

If suppliers did not provide information as requested, or the data did not appear to be reliable or was
conflicting, the Conflict Minerals Team developed a plan to send additional communications, offer additional education, or, if necessary, have the Company’s procurement organization engage with the supplier.

4. Carry out independent third-party audit of the supply chain due diligence at identified points in the
supply chain

As a downstream purchaser of conflict minerals, the Company’s due diligence process is based on the
necessity of relying on data obtained from its direct suppliers. The Company also relies on information collected and provided by other external audit programs. As such, the Company has not conducted third- party audits of any smelters or refiners.

5. Report on Supply Chain Due Diligence

This Conflict Minerals Report is on file with the SEC and is publicly available on the Company’s website at http://teledyne.com/aboutus/ethics.asp.

Results of Due Diligence

The Company, through Assent’s software platform, surveyed a total of 4,137 suppliers. Of the 2,177
responses, 219 were determined to be out of scope, 157 were deemed invalid and marked for follow-up, and 1,801 were accepted as complete. This is an overall response rate of 53%.

Smelters or Refiners

The large majority of the responses received from the supplier survey provided data at a company or
divisional level or were unable to specify the smelters or refiners used for components supplied to the Company. The Company was therefore unable to determine whether the 3TGs reported by the suppliers were contained in components or parts supplied to the Company. Furthermore, suppliers did not always provide smelter lists nor were the smelter lists consistently completed with smelter identification numbers, and therefore the Company was unable to validate that any of these smelters or refiners are actually in its supply chain.

The current efforts focus on gathering smelter information via the CMRT and, as the program progresses, requiring full completion of all necessary smelter identification information which will enable the validation and disclosure of the smelters as well as the tracing of 3TGs to their location of origin. Seeking information about 3TG smelters and refiners in the Company’s supply chain represents the most reasonable effort the Company can make to determine the mines or locations of origin of 3TGs in its supply chain.

Certain of the responses provided by suppliers to the CMRT did include the names of facilities listed by the suppliers as smelters or refiners. The Company does not typically have a direct relationship with 3TG smelters and refiners and does not perform or direct audits of these entities within its supply chain. Assent compared facilities listed in the supplier responses to the list of smelters maintained by the CFSI and the LBMA and, if a supplier indicated that the facility was certified as conflict-free, confirmed that the name was listed by CFSI. Based on the smelter lists provided by suppliers via the CMRTs, the Company is aware that 214 smelters are certified conflict free, and a number of other smelters are active in the CFSP third-party audit process.

As of May 2, 2016, the Company has validated 320 smelters or refiners and is working to validate the
additional smelter and refiner entries from the submitted CMRTs. The table set forth on Annex 1 to this Report lists the valid smelters identified by suppliers the Company surveyed. The table set forth on Annex 2 lists the countries from which the minerals processed by the SORs in Annex 1 are believed to have originated. As noted above, since the Company’s suppliers generally provided facility information via the CMRT at the company or divisional level, and generally did not limit their CMRT responses to facility information for 3TGs in products they supply to the Company specifically, 3TGs contained in the Company’s products did not necessarily originate in the facilities
listed in Annex 1 or the countries listed in Annex 2.

Many suppliers are still unable to provide the smelters or refiners used for materials supplied to the
Company. Furthermore, many of the responses provided at the company or division level indicated an “unknown” status in terms of determining the origin of 3TGs.

Risk Mitigation Steps

Year four of the Company’s conflict minerals program will continue to focus on vetting smelter data, which may include the following actions:
• Working with suppliers to move to version 4.10 of the CMRT where new smelter identification numbers have been assigned;
• Requiring the use of smelter identification numbers;
• Requesting that suppliers connect any identified smelters with the products and parts the suppliers supply to the Company; and
• Comparing smelters reported by suppliers on the CMRT to the Conflict-Free Sourcing Initiative’s list of smelters.

The Company intends to take additional steps to improve its due diligence process and to further mitigate any risk that the necessary conflict minerals in its products could benefit armed groups in the Covered Countries, which may include the following:
• Include a conflict minerals flow-down clause in new or renewed supplier contracts;
• Refine the number of suppliers requested to supply information;
• Engage with suppliers and direct them to training resources to increase the response rate and improve the content of the supplier survey responses; and
• Engage any suppliers found to be providing the Company with conflict minerals from sources that support conflict in the Covered Countries to establish an alternative source of conflict minerals that does not support such conflict.

In accordance with the Conflict Minerals Rule, a copy of this Report will be posted on the Company’s website at http://teledyne.com/aboutus/ethics.asp.

3 The CFSI generally does not specify individual countries of origin of the conflict minerals processed by compliant smelters and refiners and thus we were not able to determine with certainty the specific countries of origin of the conflict minerals processed by the listed compliant smelters and refiners. In addition, for some of the listed compliant smelters and refiners, origin information is not disclosed. The list is based on the country of origin data provided to the CFSI for compliant smelters only.
