Proxy Statement

DEFINED TERMS In this Proxy Statement, Teledyne Technologies Incorporated is sometimes referred to as the “Company” or “Teledyne”.

TELEDYNE TECHNOLOGIES INCORPORATED | 2026 Proxy Statement

Notice of Internet Availability

Pursuant to rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we have elected to furnish our Proxy Statement and Company’s Annual Report on Form 10-K for the year ended December 28, 2025 (the “2025 Annual Report”) to certain of our stockholders over the Internet, which allows us to reduce costs associated with the Annual Meeting and helps to reduce the environmental impact and costs of printing and distributing paper copies of proxy materials. On or about March 12, 2026, the Company will mail to each stockholder (other than those stockholders who previously had requested paper delivery of proxy materials) a Notice of Internet Availability of Proxy Materials containing instructions on how to access and review the proxy materials, including this Proxy Statement and the Company’s 2025 Annual Report online (the “eProxy Notice”). The eProxy Notice also contains instructions on how to request a paper copy of the Proxy Statement and 2025 Annual Report. Stockholders who have previously requested paper delivery of proxy materials will receive printed copies of the Proxy Statement and the 2025 Annual Report, which will be mailed to such stockholders on or about March 12, 2026.

Cautionary Statements

Disclosures in this Proxy Statement may contain certain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”). Statements that do not relate strictly to historical or current facts are forward-looking and usually identified by the use of words such as “anticipate,” “estimate,” “approximate,” “expect,” “intend,” “plan,” “believe” and other words of similar meaning in connection with any discussion of future operating or financial matters. Without limiting the generality of the foregoing, forward-looking statements contained in this Proxy Statement include the matters discussed regarding the expectation of performance under compensation plans, and anticipated financial and operational performance of the Company. The forward-looking statements contained in this Proxy Statement involve risks and uncertainties that could cause actual results to differ materially from projected results. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. The Company has based these forward-looking statements on current expectations and assumptions about future events, taking into account information currently known to the Company. Although the Company considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks and uncertainties, many of which are difficult to predict and are beyond the Company’s control. The risks and uncertainties that may affect the operations, performance and results of the Company’s business and forward-looking statements include, but are not limited to, those set forth in Item 1A, “Risk Factors” in the 2025 Annual Report, and in the other documents the Company files from time to time with the SEC.

Any forward-looking statement speaks only as of the date on which such statement is made, and the Company does not intend to correct or update any forward-looking statements, whether as a result of new information, future events or otherwise.

Incorporation by Reference

Neither the Personnel and Compensation Committee Report nor the Audit Committee Report shall be deemed soliciting material or filed with the SEC and neither of them shall be deemed incorporated by reference into any prior or future filings made by us under the Securities Act or the Exchange Act, except to the extent that we specifically incorporate such information by reference. In addition, this document includes several website addresses and references to our corporate social responsibility (“CSR”) reports. These website addresses are intended to provide inactive, textual references only. The information on these websites and in our CSR reports is not part of this Proxy Statement.
