SUPPLIER AND SERVICE PROVIDER BULLETIN
To Our Valued Suppliers and Service Providers:
It is appropriate during this holiday season that Teledyne Technologies Incorporated recognizes
our third-party sales and supply channels and other service providers who make it possible for us tomanufacture our products and fulfill our customers’ requirements. Thank you for your support as we facecontinuing global economic, supply chain and other challenges and conflicts. We want to extend ourwarmest wishes for a joyous, safe and healthy holiday season to you, your employees and their families.
Please remember that Teledyne has a policy that prohibits Teledyne employees and their families
from accepting gifts or gratuities from our service providers, or any party from providing gifts or gratuities
to our customers or business partners on our behalf, except in limited circumstances. It is in both ourinterests to avoid even the appearance of any form of favoritism or conflict of interest. We are certain thatyou share our desire to act in a manner consistent with the law, our policies and our commitment to ethicalbusiness practices.
We would also like to take this opportunity to remind you of our Ethics Code of Conduct forService Providers, which all Teledyne third party sales and supply channels and other service providers are
expected to follow. The Code can be found online at: http://www.teledyne.com/who-we-are/ethics. As areminder, one requirement within the Code is that no Teledyne service provider shall engage in or
facilitate forced labor, child labor, slavery or human trafficking. We expect our service providers toprovide a healthy and safe workplace -- one that is free from harassment and discrimination.
Again, we are thankful for the support from our service providers. We must continue to coordinate
our efforts to keep trade open and ensure the integrity of the supply and distribution of Teledyne products.
We recognize that in difficult times there can be added pressures and want to emphasize that we must notcompromise either the quality of our products or our ethical values. With reported shortages, we must
continue to be on alert to assure that counterfeit parts are not introduced into our supply chains. We
expect that our service providers will work with us to manage through these times successfully and withintegrity.
Additionally, over the last few years, cyber criminals have sought to misappropriate payments bypretending to be service providers and requesting diversion of funds. Some have also tried to divert
product shipments to illegitimate destinations. We expect our service providers to have adequatecybersecurity and accounting controls to ensure their employees recognize questionable electronic
communications to confirm requested changes. We also note the increase in data extortion, and expect ourservice providers to effectively protect our sensitive and controlled information, and to notify us if theybelieve Teledyne information has been compromised in a cyber attack on their systems.
Should you have questions regarding Teledyne’s ethical business conduct requirements, you may
