Customers

We have a broad and diversified customer base in the various markets we serve. No commercial customer in 2023 or 2022 accounted for more than 10% of net sales for any of our segments or for the total Company.

Total sales to international customers were $2,740.1 million in 2023 and $2,586.0 million in 2022. Of these net sales to international customers, our businesses in the United States accounted for $900.5 million in 2023 and $837.9 million in 2022.

In both 2023 and 2022, we sold products to customers in over 100 foreign countries. Approximately 90% of our net sales to international customers during 2023 were made to customers in 30 foreign countries. In 2023, the top five countries for sales to international customers, ranked by net sales, were the United Kingdom, China, Japan, Germany and Norway and represented approximately 21% of our total net sales. There were no sales to individual countries outside of the United States in excess of 10% of the Company’s sales.

Information on our net sales to the U.S. Government, including direct sales to agencies as a prime contractor and indirect sales as a subcontractor, was as follows (in millions):

U.S. Government sales by segment:	2023			2022			2021
Digital Imaging	$	570.7		$	619.1		$	515.9
Instrumentation	95.9			108.1			91.6
Aerospace and Defense Electronics	330.3			266.3			227.2
Engineered Systems	384.8			366.4			358.4
Total U.S. Government sales	$	1,381.7		$	1,359.9		$	1,193.1

Total U.S. Government sales as a percent of total net sales	24.5		%	24.9		%	25.9		%

Our principal U.S. Government customer is the U.S. Department of Defense, with total net sales of $1,081.3 million and $1,065.1 million in 2023 and 2022, respectively. With the exception of the Engineered Systems segment, no U.S Government program in 2023 or 2022 accounted for more than 10% of net sales for any of our segments or for the total Company. In 2023, the largest program with the U.S. Government within the Engineered Systems segment was the Marshall Operations, Systems, Services, and Integration II (“MOSSI II”) contract with the NASA Marshall Space Flight Center, which represented approximately 17% of Engineered Systems net sales. In 2022, the largest program with the U.S. Government within the Engineered Systems segment was the Mission Operations and Integration contract with the NASA Marshall Space Flight Center, which represented approximately 11% of Engineered Systems net sales.

As described in greater detail under Item 1A. Risk Factors, there are risks associated with doing business with the U.S. Government. In 2023, approximately 79% of our U.S. Government prime contracts and subcontracts were fixed-price type contracts, compared to 80% in 2022, with the remaining U.S. Government contracts related to cost-reimbursable contracts (“cost-type”) contracts. Under fixed-price type contracts, we bear the inherent risk that actual performance cost may exceed the fixed contract price. Such contracts are typically not subject to renegotiation of profits if we fail to anticipate technical problems, estimate costs accurately or control costs during performance. Additionally, U.S. Government contracts are subject

to termination by the U.S. Government at its convenience, without identification of any default. When contracts are terminated for convenience, we can recover costs incurred or committed, settlement expenses and profit on work completed prior to termination. During 2023 and 2022, contracts terminated by the U.S. Government did not materially impact our results of operations.

Many of our government contracts are awarded after a competitive bidding process in which we seek to emphasize our ability to provide superior products and technical solutions.

Raw Materials and Suppliers

Most raw materials used in our operations are readily available; however, we have experienced supply chain challenges in recent years, including increased lead times, as well as cost inflation for parts and components, logistics and labor due to availability constraints and high demand. Some raw materials are purchased from a limited set of suppliers, including international sources, due to technical capability, price, and other factors. We leverage our existing supplier relationships and are not dependent on any one supplier for a material amount of our purchases. While some of our businesses provide services, for those businesses that sell products, a portion of the value that we provide is labor-oriented, such as design, engineering, assembly and test activities. In manufacturing our products, we use our own production capabilities and third-party suppliers and subcontractors, including international sources.

Marketing

Our sales and marketing approach varies by segment and by products within our segments. A shared fundamental tenet is the commitment to work closely with our customers to understand their needs, with an aim to secure preferred supplier and longer-term relationships. Given the technical nature of our products, we conduct our marketing activities through a direct internal sales force as well as third-party sales representatives and distributors. Several Teledyne businesses, including across our segments, have been marketing and selling products collaboratively to similar customers.

Competition

Because of the diversity of products sold and the number of markets we serve, we encounter a wide variety of

competitors, none of which we believe offer the same product and service lines or serve all of the same markets as we do. Although we have certain advantages that we believe help us compete effectively in our markets, each of our markets is highly competitive. Our businesses compete on quality, product performance and reliability, technical expertise, price and service. Many of our competitors have, and potential competitors could have, greater name recognition, a larger installed base of products, more extensive engineering, manufacturing, marketing and distribution capabilities and greater financial, technological and personnel resources than we do.

Intellectual Property

We own and control various intellectual property rights, including patents, trade secrets, confidential information, trademarks, trade names, and copyrights. We license patents, technology and other intellectual property rights owned and controlled by others. Similarly, other companies license patents, technology and other intellectual property rights owned and controlled by us. We do not consider any single patent or trademark, or any group of them, essential either to Teledyne’s business as a whole or to any one of our reportable segments. The annual royalties received or paid under license agreements are not significant to any of our reportable segments or to our overall operations.

Patents, patent applications and license agreements will expire or terminate over time by operation of law, in accordance with their terms or otherwise. We do not expect the expiration or termination of these patents, patent applications and license agreements to have a material adverse effect on our business, results of operations or financial condition.

Environment and Other Government Regulations

Information with respect to environmental matters is set forth under “Other Matters – Environmental” of “Item 7. Management’s Discussion and Analysis of Results of Operation and Financial Condition” and Note . No material capital expenditures relating to environmental compliance are presently anticipated. See Note 17 for additional discussion of other government regulations.

Sustainability

Teledyne continues to focus on developing solutions to address sustainability and climate challenges facing humanity today. Many of our products directly support sustainability and climate challenges. We provide a broad range of precision measurement technologies for environmental monitoring and climate research. Our sensors and instruments are deployed everywhere: in space, on aircraft and drones, on land, on the sea surface, in the water column, and on the seafloor. They operate around the clock, measuring greenhouse gases from space, precisely monitoring air and water quality throughout the world, and continuously profiling the Earth’s oceans. Applications of our instruments provide scientists information that spans

time from the origin of the universe to providing real-time data regarding air pollution and dangerous storms, such as time-critical warning of hurricanes and tsunamis.

The prominence and importance of sustainability and Environmental, Social and Governance (“ESG”) initiatives have dramatically increased. In November 2022, we published our second Corporate Social Responsibility (“CSR”) report, in which we disclose and highlight some of our most recent efforts focused on sustainability and ESG. We published a supplement to the CSR report in November 2023 to include updated financial information and other information in the report. The CSR report together with its supplement, which is not incorporated by reference in this document, is available at the Corporate Social Responsibility link on our website at www.teledyne.com under the tab “Who We Are”. The CSR Report and its supplement includes data on Teledyne’s combined direct emissions (“Scope 1”) and indirect emissions from purchased energy (“Scope 2”), workplace safety, water usage, waste generation and recycling and workplace demographics.

In 2021, we compiled the first global inventory of our greenhouse gas (“GHG”) emissions (starting with fiscal year 2020) and have developed a GHG monitoring and management plan. We have set a goal to reduce our combined Scope 1 and Scope 2 in company operations, normalized for revenue, by 40% from 2020 levels by the end of 2040. Going forward, we will continue to evaluate our emission reduction goals, while at the same time providing the tools and technologies enabling environmental science and climatology across the globe. More information about our carbon footprint and GHG emission reduction efforts and goals, and the contributions that Teledyne products make to carbon monitoring and environmental and climate science, can be found in our CSR report.

Pursuant to the mandate in their respective charters, the Audit Committee of our Board of Directors (the “Board”) regularly reviews matters related to compliance with environmental laws and the health and safety of employees, and the Nominating and Governance Committee of our Board reviews and evaluates our policies and practices and monitors our efforts in areas of legal and social responsibility, diversity and sustainability, and other ESG matters.

Human Capital

We consider our relations with our employees to be good. At December 31, 2023, our total workforce consisted of approximately 14,900 employees in 36 countries. Workforce demographics for various regions are provided below:

We are focused on attracting, developing, and retaining employees through competitive compensation and benefits, workforce and management development, diversity and inclusion initiatives, succession planning, corporate culture and leadership quality.

Teledyne has a Corporate-led committee to oversee our diversity, equity and inclusion efforts. The committee focuses on activities and initiatives to increase diverse representation and progression within our company. Various initiatives include developing relationships with universities with higher underrepresentation, creating more diverse and larger talent pools, and increasing networking and referrals with diverse professional organizations. We advertise vacancies and strive to recruit the best possible candidate for each role. We monitor diversity metrics on a global basis.

The health and wellness of our employees is a critical component to the success of our business. Many of our larger facilities have on-site fitness centers and encourage healthy choices with various wellness challenge programs. These programs often include guest speakers on various topics, including mental health, heart disease, diabetes, and personal financial awareness. We also have vacation and sick leave policies that provide employees with flexibility to take time away from work for relaxation or to recover from illness. The majority of our employees (including all full-time employees in the U.S., Canada and the United Kingdom) have access to our employee assistance program which includes third-party counseling and mental health services at no cost to the employee when life events impact an employee.

We are committed to identifying and developing the talents of our next generation of leaders. On an annual basis, we conduct an organization and leadership review for all segment, business unit, and function leaders, focusing on our high performing and high potential talent, diversity and succession for our most critical roles. From this review, individualized development and retention programs are implemented or revised as needed. We also provide additional opportunities for our existing employees to enhance their careers. We invest in employee skills development in various ways, including through educational expense reimbursement. Specialized training in a job-related field gives employees new skills and a strong

foundation of knowledge that can serve them throughout their career and that may allow them to progress to more responsible positions at Teledyne. Our employees have access to Teledyne University, a learning platform. The database of courses, webinars, and certification programs has hundreds of targeted training programs on management, technical competencies, soft skills development, and compliance.
