REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Plan Participants and Plan Administrator of

Teledyne Technologies Incorporated 401(k) Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of Teledyne Technologies Incorporated 401(k) Plan (the "Plan") as of December 31, 2025 and 2024, the related statement of changes in net assets available for benefits for the year ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the Plan's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Report on Supplemental Schedules

The Supplemental Schedule of Assets (Held at End of Year) as of December 31, 2025 and Schedule of Delinquent Participant Contributions for the Year Ended December 31, 2025 have been subjected to audit procedures performed in conjunction with the audit of the Plan's financial statements. The supplemental schedules are the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental schedules reconcile to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedules. In forming our opinion on the supplemental schedules, we evaluated whether the supplemental schedules, including their form and content, are presented in compliance with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, such schedules are fairly stated, in all material respects, in relation to the financial statements as a whole.

Teledyne Technologies Incorporated 401(k) Plan

Notes to Financial Statements

December 31, 2025

1. Description of the Plan

General

The Teledyne Technologies Incorporated 401(k) Plan (the “Plan”) is a defined contribution plan available to eligible U.S. domestic employees of Teledyne Technologies Incorporated (“Plan Sponsor”) and certain subsidiaries (collectively, “Teledyne” or the “Company”). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). Fidelity Management Trust Company (“Fidelity”) acts as the trustee and record-keeper of the Plan. The Plan was adopted and effective on April 1, 2000, and has been subsequently amended and restated effective on December 31, 2015, with the most recent restatement adopted on December 1, 2022, with the latest amendment made on December 18, 2025. For a more complete description of the Plan’s provisions please refer to the Plan document.

In December 2024, Teledyne acquired Micropac Industries, Inc. (“Micropac”). Micropac employees who were eligible for the Plan, effective December 30, 2024, were permitted to rollover their eligible account balances from the Micropac Industries, Inc. Employees Profit Sharing Plan and Trust, and $7.8 million was rolled into the Plan during 2025.

In January 2025, Teledyne acquired select aerospace and defense electronics businesses from Excelitas Technologies Corp. Employees of the U.S.-based advanced electronic systems business (“Qioptiq”), who were eligible for the Plan, effective January 31, 2025, were permitted to rollover their eligible account balances from the Excelitas Technologies Savings Plan, and $7.3 million was rolled into the Plan during 2025.

Employer Contributions

Generally, the Company will match 50% of 8% of qualifying wages the employee defers to the Plan, provided that total matching contributions do not exceed 4% of the employee’s compensation for any plan year. For employees who are eligible to accrue a benefit under the Teledyne Technologies Incorporated Pension Plan or the Teledyne Technologies Incorporated Pension Plan for Defined Active Participants (together, the “Pension Plans”), the Company will match 50% of the qualifying employee contributions up to a maximum of $1,000 annually for each participant. Employees become eligible for Company matching contributions following 90 days of service or unless expressly provided by the terms of an acquisition/sales agreement. For any exceptions to the employer contribution details above, please refer to the Plan document.

Teledyne Technologies Incorporated 401(k) Plan

Notes to Financial Statements (continued)

1. Description of the Plan (continued)

Employee Contributions

Generally, participants can defer between 1% and 50% (highly compensated employees between 1% and 15% on a pretax and/or Roth basis and up to 8% on an after-tax basis), subject to Internal Revenue Code (the “Code”) limitations, of their eligible wages and contribute them to the Plan. An employee who first becomes an eligible employee shall be deemed to have elected to contribute 6% of eligible wages following 90 days of service unless or until such deemed election is revoked by the employee. Participants who have attained the age of 50 may make catch-up contributions as defined by the Plan. These catch-up contributions are not eligible for the Company match.

The Plan allows participants to make contributions designated as “Roth contributions”, that is, contributions subject to federal income taxation in the year made but the earnings on which are not subject to federal income tax, and after-tax contributions that are not Roth contributions. Only pretax and Roth contributions are eligible for the Company match. After-tax contributions are not eligible for the Company match. Participants have the ability to convert all, or a portion of their non-Roth assets into a Roth account within the Plan. The amount eligible for conversion (contributions plus earnings) becomes taxable as ordinary income in the year of the conversion.

Beginning January 1, 2025, under the SECURE Act 2.0, participants ages 60 to 63 by December 31, 2025, are eligible for increased catch-up contributions in the Plan. The higher catch-up contribution limit for those ages 60 to 63 is $11,250.

Starting January 1, 2026, under the SECURE Act 2.0, catch-up contributions for certain participants will be required to be made on a Roth (after-tax) basis. Specifically, participants age 50 or older with prior-year Federal Insurance Contributions Act (FICA) wages in excess of the applicable Internal Revenue Code threshold will no longer be permitted to make pretax catch-up contributions. The Plan will be amended to reflect any changes made in response to SECURE Act 2.0 by the deadlines prescribed in the legislation.

Participant Accounts

Separate accounts are maintained by the record-keeper for each participant. Each participant may direct his or her account balance into one or more investment options offered by the Plan or a self-directed brokerage link investment option. The self-directed brokerage link investment option allows the participant to direct contributions to be invested in any investment permitted under the Plan, including mutual funds, common stock and bonds. Asset management fees charged for the administration of all funds are charged against net assets available for benefits of the respective fund.

Vesting and Forfeitures

Participants who are eligible to accrue a benefit under the Pension Plans are 100% vested in their 401(k) Plan contributions, Company matching contributions and all earnings thereon. Participants who are not eligible to accrue a benefit under the Pension Plans will at all times have a 100% vested interest in their accounts, except for the Company Match Account and all earnings thereon which is fully vested after five years of vesting service.

When certain terminations of participation in the Plan occur, the nonvested portion of the participant’s account, as defined by the Plan, represents a forfeiture. The Plan document permits the use of forfeitures to first pay the Plan’s ordinary and necessary administrative expenses for the Plan year and then to reduce the Company’s matching contribution for the Plan year in which the forfeiture occurs or any following plan year. At December 31, 2025 and 2024, forfeited nonvested accounts totaled $0.3 million. During 2025, employer contributions were reduced by $1.4 million from forfeited nonvested accounts.

Teledyne Technologies Incorporated 401(k) Plan

Notes to Financial Statements (continued)

1. Description of the Plan (continued)

Participant Loans

Active employees can borrow up to 50% of their vested account balances. The loan amounts are further limited to a minimum of $500 and a maximum of $50,000, and an employee can have no more than one loan outstanding at any given time. Interest rates are determined based on commercially accepted criteria, and payment schedules vary based on the type of loan. Loans may be paid in full or in part at any time. Loans are repayable over periods of up to five years (15 years for loans to purchase the participant’s primary residence). Payments are generally made through payroll deductions. As of December 31, 2025, participant loans have maturities through 2040 at interest rates ranging from 3.25% to 10.25%.

Plan Termination

In the event that the Plan is terminated, or the Plan Sponsor permanently discontinues making contributions, all amounts credited to the accounts of affected participants will be distributed to participants as defined in the Plan document under the provisions of ERISA. In the event the Plan is terminated, Participants would become 100% vested in their accounts.

Withdrawals and Distributions

The Plan allows for participants to make withdrawals from the Plan upon reaching age 59½. Additionally, the value of participants’ vested account balance is payable to participants upon death, disability, retirement or upon termination of employment with the Company. At the participant’s election, payment may be made in cash, as a single lump sum, or in installments. In addition, employees who rolled their funds over as a result of the Reynolds Industries, Incorporated acquisition and have at least 20 years of service may make a withdrawal of their after-tax Company matching contributions and all earnings thereon.

In accordance with the Setting Every Community Up for Retirement Enhancement (“SECURE”) Act of 2019, the Plan increased the Required Minimum Distribution (“RMD”) age to 72 in lieu of age 70 ½. On December 29, 2022, the SECURE Act 2.0 was signed into law, which built on the original SECURE Act’s focus on expanding retirement plan coverage and participation. In accordance with the SECURE Act 2.0, participants who attain age 72 after December 31, 2022, will begin receiving benefit payments no later than April 1 of the calendar year following the calendar year in which they attain age 73.

Administrative Expenses

The Company pays administrative expenses, which include recordkeeping and trustee fees as well as expenses incurred in administering the Plan. Participants pay loan origination and servicing fees.

The Plan has a revenue-sharing agreement whereby certain investment managers return a portion of the investment fees to the record-keeper to offset the Plan’s administrative expenses. Future plan expenses can be paid from any excess remaining revenue-sharing amounts. For the year ended December 31, 2025, $0.2 million was used to offset plan expenses. The Plan held undistributed administrative revenues of $0.4 million and $0.2 million at December 31, 2025 and 2024, respectively.

2. Significant Accounting Policies

Basis of Accounting

The accompanying financial statements of the Plan have been prepared on an accrual basis in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date.

Payment of Benefits

Benefits are recorded when paid.

Contributions

Employee contributions and employer matching contributions are recorded when withheld.

Teledyne Technologies Incorporated 401(k) Plan

Notes to Financial Statements (continued)

2. Significant Accounting Policies (continued)

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2025 or 2024. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced, and a benefit payment is recorded.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Recent Accounting Pronouncements

There have been no new accounting pronouncements reflected in the 2025 financial statements.

3. Fair Value Measurements

Valuation of Investments

The Plan’s investments are stated at fair value. Fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2025 and 2024.

Mutual Funds: Valued at the quoted net asset value (“NAV”) of shares held by the Plan at year end.

Teledyne Technologies Incorporated Common Stock Fund: The Teledyne Technologies Incorporated Common Stock Fund is a real-time traded stock that trades with the current market price or closing price of the common stock.

Self-Directed Brokerage Link: Valued at quoted market prices in an active market on the last business day of the Plan year.

Collective Trusts: Units held in collective trusts (“CT”) are valued using the net asset value practical expedient (“NAV practical expedient”) of the CT as reported by the CT managers. The NAV practical expedient is based on the fair value of the underlying assets owned by the CT, minus its liabilities, and then divided by the number of units outstanding. The beneficial interest in the net assets of each portfolio is represented by units. NAV per unit is determined each business day. Issues and redemptions of units are recorded, upon receipt of unit holder’s instructions in good order, based on the next determined NAV per unit, normally each day. In unusual market conditions, the trustee may in its sole discretion, impose restrictions on issues and redemptions of units. The issuance and redemption provisions of the underlying funds are consistent with those of the portfolios. In certain circumstances units may be purchased or redeemed through the exchange of securities, the fair value of which is used to determine the number of units issued or redeemed.

While the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Teledyne Technologies Incorporated 401(k) Plan

Notes to Financial Statements (continued)

3. Fair Value Measurements (continued)

In accordance with U.S. GAAP, each of the Plan’s fair value measurements are categorized using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level l measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 - Inputs to the valuation methodology include:

•Quoted prices for similar assets or liabilities in active markets

•Quoted prices for identical or similar assets or liabilities in inactive markets

•Inputs other than quoted prices that are observable for the asset or liability

•Inputs that are derived principally from or corroborated by observable market data by correlation or other means

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Notes to Financial Statements (continued)

3. Fair Value Measurements (continued)

The following tables set forth by level, within the fair value hierarchy, the Plan’s assets at fair values as of December 31, 2025 and 2024 (in thousands):

Investments measured at net asset value as a practical expedient:
Collective trusts (includes Fidelity MIP)							1,611,457

Total investments at fair value							$	2,068,059

4. Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service (“IRS”) dated May 13, 2024, stating that the Plan is qualified under Section 401(a) of the Code and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. Subsequent to this determination by the IRS, the Plan was amended. The Company and Plan management believe that the Plan is currently designed and operated in compliance with the applicable requirements of the Code, and the Plan and related trust continue to be tax-exempt. Therefore, no provision for income taxes has been included in the Plan’s financial statements.

U.S. GAAP requires plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2025, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

Notes to Financial Statements (continued)

5. Parties-in-Interest

During 2025, the Plan invested in mutual funds and collective trust funds managed by Fidelity. The Fidelity managed funds qualify as exempt party in interest transactions. Trustee and investment fees paid by the Plan during 2025 was $0.8 million.

One of the investment options available to participants is the Teledyne Technologies Incorporated Common Stock Fund valued at $94.0 million and $93.4 million at December 31, 2025 and 2024, respectively. The plan held 184,106 and 201,142 shares of Teledyne Technologies Incorporated common stock at December 31, 2025 and 2024, respectively with a cost basis of $31.9 million as of December 31, 2025.

6. Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market volatility and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

7. Delinquent Participant Contributions

Employee withholdings of $292 were not remitted to the Plan within the typical time period by the Company. Lost earnings were minimal and were remitted to the Plan in July 2025.

8. Subsequent Events

Effective January 1, 2026, an employee who first becomes an eligible employee shall be deemed to have elected to contribute 8% of eligible wages following 90 days of service unless or until such deemed election is revoked by the employee.

Management evaluated subsequent events for the Plan through June 26, 2026, the date the financial statements were available to be issued.
