Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with generally accepted accounting principles in the United States (“GAAP”) as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (“2023 Form 10-K”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of September 29, 2024 and the consolidated results of operations, consolidated comprehensive income (loss) and consolidated cash flows for the third quarter and nine months ended September 29, 2024. The results of operations and cash flows for the periods ended September 29, 2024 and cash flows for the nine months ended September 29, 2024 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Recent Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires a public entity to disclose significant segment expenses and other segment items on an interim and annual basis. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.

During the second quarter of 2024, the Company acquired Valeport Holdings 2019 Limited and its affiliates ("Valeport") for $35.5 million in cash, net of cash acquired, subject to certain adjustments. Approximately 10% of the purchase price is payable in fiscal year 2025. Valeport, founded in 1969 and headquartered in Totnes, United Kingdom, designs and manufactures underwater sensors for environmental, energy, construction and defense applications. Valeport is part of the Marine Instrumentation product line within the Instrumentation segment. Goodwill resulting from the Valeport acquisition will not be deductible for tax purposes. 2023 Acquisitions Xena Networks During the fourth quarter of 2023, the Company acquired Xena Networks ApS and affiliates (“Xena Networks”) for $24.2 million in cash, net of cash acquired, and subject to certain adjustments. Xena Networks, headquartered in Denmark, is a leading provider of high-speed terabit ethernet validation, quality assurance, and production test solutions. Xena Networks is part of the Test and Measurement Instrumentation product line within the Instrumentation segment. Goodwill resulting from the Xena Networks acquisition will not be deductible for tax purposes. ChartWorld During the first quarter of 2023, the Company acquired ChartWorld International Limited and affiliates ("ChartWorld") for $53.5 million in cash, net of cash acquired, and subject to certain adjustments. ChartWorld, headquartered in Cyprus, with additional locations in Germany, Singapore, Canada and Japan, is a provider of digital marine navigation hardware and software provided through an affordable subscription-based model. ChartWorld is part of the Digital Imaging segment. Goodwill resulting from the ChartWorld acquisition will not be deductible for tax purposes. The following tables show the purchase price (net of cash acquired), goodwill acquired, and acquired intangible assets for these acquisitions (in millions): 2024 Acquisitions Acquisition Date Consideration Transferred (a) Goodwill Acquired Acquired Intangible Assets Adimec June 4, 2024 $ 88.7 $ 64.7 $ 17.9 Valeport April 10, 2024 35.0 23.0 7.8 $ 123.7 $ 87.7 $ 25.7 (a) Net of cash acquired; approximately 10% of the Valeport purchase price is payable in 2025 and included in the amount above 2023 Acquisitions Acquisition Date Consideration Transferred (a) Goodwill Acquired Acquired Intangible Assets Xena Networks October 13, 2023 $ 24.2 $ 21.1 $ 4.8 ChartWorld January 3, 2023 53.5 55.5 11.3 Total $ 77.7 $ 76.6 $ 16.1 (a) Net of cash acquired The Company’s cost to acquire these acquisitions was allocated to the assets acquired and liabilities assumed based upon their respective fair values as of the date of the completion of the acquisition. The differences between the fair value of the consideration paid and the estimated fair value of the assets and liabilities acquired was recorded as goodwill. The fair value of the acquired identifiable assets and liabilities for the Adimec, Valeport and Xena Networks acquisition is provisional pending finalization of the Company’s acquisition accounting, including the measurement of tax basis in certain jurisdictions and the resulting deferred taxes that might arise from book and tax basis differences, if any. Pro forma results of operations, the revenue and net income subsequent to the acquisition date, and a more detailed breakout of the major classes of assets and liabilities acquired for these acquisitions have not been presented because the effects of these acquisitions, individually and in the aggregate, were not material to the Company's financial results. The significant factors that resulted in recognition of goodwill for the 2023 and 2024 acquisitions included the acquired businesses’ market positions, growth opportunities in the markets in which they operate, their experienced work force and established operating infrastructures. The results of these acquisitions have been included in Teledyne’s results since the dates of their respective acquisition.

Net sales in the Engineered Systems segment are typically between 45% and 55% fixed price contracts in a given reporting period, with the balance of net sales derived from cost-reimbursable type contracts. For the nine months ended September 29, 2024, approximately 51% of net sales in the Engineered Systems segment were derived from fixed price contracts. Contract Liabilities Balance at Contract Liabilities by Balance Sheet Location (in millions) September 29, 2024 December 31, 2023 Accrued liabilities $ 326.7 $ 241.1 Other long-term liabilities 29.4 25.5 Total contract liabilities $ 356.1 $ 266.6 The Company recognized revenue of $130.3 million during the nine months ended September 29, 2024 from contract liabilities that existed at the beginning of year. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for which work has not been performed as of the period end date and exclude unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity). As of September 29, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $3,578.4 million. The Company expects approximately 77% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 23% recognized thereafter. Changes in Contract Estimates at Completion For over time contracts using the cost-to-cost method, the Company has an Estimate at Completion (“EAC”) process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue, determining reasonably dependable cost estimates, and making assumptions for schedule and technical issues. The majority of revenue recognized over time uses an EAC process. Since certain contracts extend over a long period of time, the impact of revisions in cost and revenue estimates during the progress of work may adjust the current period earnings through a cumulative catch-up basis. This method recognizes, in the current period, the cumulative effect of the changes on current and prior quarters. Additionally, if the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract cost and revenue estimates for significant contracts are generally reviewed and reassessed quarterly. The net aggregate effects of these changes in estimates on contracts accounted for under the cost-to-cost method in the first nine months of 2024 was $5.1 million of favorable operating income compared with $1.7 million of favorable operating income in the first nine months of 2023. None of the effects of changes in estimates on any individual contract were material to the condensed consolidated statements of income (loss) for any period presented.

Based on the results of the Company’s annual assessment in the fourth quarter of 2023, all reporting units with the exception of the FLIR reporting unit in the Digital Imaging segment had estimated fair values that exceeded their respective carrying value by more than 100%. At the assessment date in the fourth quarter of 2023, the estimated fair value of the FLIR reporting unit exceeded its carrying value by approximately $460 million or 6%, and the FLIR reporting unit had $5,832.4 million of goodwill at the prior year assessment date. As of September 29, 2024, the FLIR reporting unit had $5,884.9 million of goodwill, with the change in value from the prior year assessment date related to the impact of foreign currency translation. Although the assumptions used in the Company’s prior year discounted cash flow model and market approach are based on assumptions that are considered reasonable by management and consistent with the plans and estimates management uses to operate the underlying businesses, there is significant judgment in determining the expected results of the FLIR reporting unit. Changes in forecast estimates or the application of alternative assumptions could produce significantly different results. The discount rate, which is consistent with a weighted average cost of capital that is likely to be expected by a market participant, is based upon industry required rates of return, including consideration of both debt and equity components of the capital structure. Although no impairment existed for the FLIR reporting unit as of the prior year assessment date, a non-cash impairment of goodwill could result from a number of circumstances, including different assumptions used in determining the fair value of the reporting unit, changes to customer spending priorities, or a sharp increase in interest rates without a corresponding increase in future net sales. For all reporting units, including the FLIR reporting unit, there have been no events or changes in circumstances which indicate that it is more likely than not that the fair value of the reporting unit is below its carrying value. As such, no interim impairment review was required. The Company will perform its annual analysis during the fourth quarter of 2024. Based on the results of the Company’s annual assessment in the fourth quarter of 2023, the estimated fair value of all material indefinite-lived trademarks, with the exception of the FLIR indefinite-lived trademark, significantly exceeded their respective carrying value. Trademarks of recently acquired businesses generally represent a higher inherent risk of impairment, which typically decreases as the businesses are integrated into the Company. At the prior year annual assessment date, the FLIR indefinite-lived trademark had a carrying value of $685.3 million and a fair value of $694.9 million. The most significant assumptions utilized in the determination of the fair value of the FLIR trademark are the net sales growth rates (including residual growth rates), discount rate and royalty rate. Although the FLIR sales forecasts are based on assumptions that are considered reasonable by management and consistent with the plans and estimates management uses to operate the underlying businesses, there is significant judgment in determining the expected results of the FLIR business. Changes in sales forecast estimates or the application of alternative assumptions could produce significantly different results. The discount rate, which is consistent with a weighted average cost of capital that is likely to be expected by a market participant, is based upon industry required rates of return, including consideration of both debt and equity components of the capital structure. The royalty rate was driven by historical and estimated future profitability of the underlying FLIR business, and the royalty rate assumption was consistent with assumptions used by the Company as part of the purchase price allocation of FLIR in 2021. The royalty rate may be impacted by significant adverse changes in long-term operating margins. Although no impairment exists for the FLIR trademark, a non-cash impairment of the trademark could result from a number of circumstances, including different assumptions used in determining the fair value of the trademark, changes to customer spending priorities, or a sharp increase in interest rates without a corresponding increase in future net sales. For all indefinite-lived trademarks, including the FLIR trademark, there have been no events or changes in circumstances which indicate that it is more likely than not that the fair value of the trademark is below its carrying value. As such, no interim impairment review was required. The Company will perform its annual analysis during the fourth quarter of 2024.

Income Taxes	Income Taxes The income tax provision is calculated using an estimated annual effective tax rate, based upon estimates of annual income, permanent items, statutory tax rates and planned tax strategies in the various jurisdictions in which we operate except that certain loss jurisdictions and discrete items, such as the resolution of uncertain tax positions and stock-based accounting income tax benefits, are treated separately. Third Quarter Nine Months (dollars in millions) 2024 2023 2024 2023 Provision (benefit) for income taxes (a) $ (7.1) $ 47.3 $ 90.7 $ 141.6 Income (loss) before income taxes $ 255.1 $ 246.1 $ 712.3 $ 704.7 Effective tax rate (2.8)% 19.2% 12.7% 20.1% (a) The third quarter of 2024 includes net discrete income tax benefits of $62.3 million and the first nine months of 2024 includes net discrete income tax benefits of $67.4 million, respectively, with the income tax benefits primarily related to the release of a net income tax reserve liability (including applicable interest and penalties) as a result of a favorable resolution reached by the Company with foreign tax authorities around transfer pricing between certain FLIR subsidiaries. The third quarter of 2023 includes net discrete income tax benefits of $6.1 million and the first nine months of 2023 includes net discrete income tax benefits of $14.1 million, respectively. Numerous foreign jurisdictions have enacted or are in the process of enacting legislation to adopt a minimum effective tax rate described in the Global Anti-Base Erosion, or Pillar Two, model rules issued by the Organization for Economic Co-operation and Development (“OECD”). A minimum effective tax rate of 15% would apply to multinational companies with consolidated revenue above €750 million. Under the Pillar Two rules, a company is required to determine a combined effective tax rate for all entities located in a jurisdiction. If the jurisdictional effective tax rate determined under the Pillar Two is less than 15%, a top-up tax will be due to bring the jurisdictional effective tax rate up to 15%. The Company is continuing to monitor the implementation of Pillar Two by individual countries and the potential effects of Pillar Two on our business. The Company does not expect the provisions effective in 2024 will have a materially adverse impact on its results of operations, financial position or cash flows. The Inflation Reduction Act of 2022 (“IRA”) levies a 1% excise tax on net stock repurchases after December 31, 2022. If the Company were to repurchase shares, the excise tax would be recorded as a cost of acquiring treasury stock and is not material. Additionally, the IRA imposes a 15% corporate alternative minimum tax (“CAMT”) for tax years beginning after December 31, 2022. The Company does not expect the CAMT to have a material impact on its results of operations or financial position.

Stock-based Compensation	Sep. 29, 2024
Share-Based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock awards and restricted stock units. The Company also has non-employee director stock compensation plans, pursuant to which common stock, stock options and restricted stock units have been issued to its directors. The Company issues shares of common stock upon the exercise of stock options. In 2024, the Company began using the Black-Scholes option pricing model to determine the fair value of stock options. The adoption of the Black-Scholes option pricing model was driven by a review of option exercise history, which more closely aligned with the methodology of the Black-Scholes option pricing model, and the adoption of the Black-Scholes option pricing model did not materially change the grant-date fair value calculation. Stock-based compensation expense was $8.7 million and $30.0 million for the third quarter and first nine months of 2024, respectively, and $8.0 million and $24.3 million for the third quarter and first nine months of 2023, respectively.

Stock Repurchases In April 2024, our Board of Directors approved a stock repurchase program authorizing the Company to repurchase up to $1.25 billion of Teledyne’s common stock. This authorization superseded prior open stock repurchase programs authorized by the Board of Directors. The newly authorized stock repurchase program does not have a stated expiration date. Shares may be repurchased from time to time in open market transactions at prevailing market prices, in privately negotiated transactions or via an accelerated stock repurchase program. Shares could be repurchased in a plan pursuant to Rule 10b5-1 of the Securities Exchange Act of 1934. The repurchase program is expected to remain open continuously, and the number of shares purchased will depend on a variety of factors, such as share price, levels of cash available, acquisitions and alternative investment opportunities available immediately or longer-term, and other regulatory, market or economic conditions. The Company currently intends to fund future share repurchases with cash on hand and available borrowings under the Company's credit facility. During the third quarter of 2024, the Company repurchased approximately 0.3 million shares for $138.8 million with a weighted-average price of $404.67 per share. During the first nine months of 2024, the Company repurchased approximately 0.8 million shares for $332.6 million with a weighted-average price of $397.14 per share. Subsequent to the end of the third quarter of 2024, the Company repurchased less than 0.1 million shares for $21.4 million with a weighted-average price of $445.85 per share.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company's primary exposure to market risk relates to changes in foreign currency exchange rates and interest rates. The Company’s primary foreign currency risk management objective is to protect the U.S. dollar value of future cash flows and minimize the volatility of reported earnings. The Company does not use foreign currency forward contracts for speculative or trading purposes. The Company mitigates exposure to foreign currency exchange rates and interest rates primarily through the following: Mitigation Approach Quantitative Information on Approach The Company utilizes foreign currency forward contracts to reduce the volatility of cash flows primarily related to forecasted revenue and expenses denominated in Canadian dollars for our Canadian companies, and in British pounds for our U.K. companies. These contracts are designated and qualify as cash flow hedges. As of September 29, 2024, the Company had foreign currency forward contracts to buy Canadian dollars and to sell U.S. dollars totaling $68.1 million. These foreign currency forward contracts have maturities ranging from December 2024 to February 2026. As of September 29, 2024, the Company had foreign currency forward contracts to buy British pounds and to sell U.S. dollars totaling $5.5 million. These foreign currency forward contracts have maturities ranging from December 2024 to February 2025. The Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign currency denominated monetary assets and liabilities, including intercompany receivables and payables. These foreign currency forward contracts are not designated as accounting hedges. See Non-Designated Hedging Activities section below. The Company has converted a U.S. dollar denominated, variable rate debt obligation of a European subsidiary into euro fixed rate obligation using a receive float, pay fixed cross currency swap to reduce the variability of interest rates. This cross currency swap is designated as cash flow hedge. As of September 29, 2024, the Company has a cross currency swap outstanding with a notional amount of €156.0 million and $150.0 million that matures in October 2024. All derivative instruments are recorded on the condensed consolidated balance sheets at fair value. The accounting for gains and losses resulting from changes in fair value depends on the use of the derivative instrument and whether it is designated and qualifies for hedge accounting. Designated Hedging Activities For a derivative instrument designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the condensed consolidated balance sheets in AOCI to the extent the derivative instrument is effective in mitigating the exposure related to the anticipated transaction. The amount recorded within AOCI is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings. The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the third quarter and nine months ended September 29, 2024 and October 1, 2023 was as follows (in millions): Third Quarter Nine Months 2024 2023 2024 2023 Net gain (loss) recognized in AOCI - Foreign Exchange Contracts (a) $ (4.5) $ 4.0 $ (3.6) $ 20.7 Net gain (loss) reclassified from AOCI into revenue - Foreign Exchange Contracts (a) $ (0.1) $ (1.1) $ 0.9 $ (4.8) Net gain (loss) reclassified from AOCI into other income and expense, net - Foreign Exchange Contracts (b) $ (6.6) $ 4.2 $ (1.7) $ 15.0 Net gain (loss) reclassified from AOCI into interest expense - Foreign Exchange Contracts $ 2.2 $ 1.9 $ 6.1 $ 5.6 Net gain (loss) reclassified from AOCI into interest expense - Interest Rate Contracts $ — $ — $ — $ 0.6 (a) Effective portion, pre-tax (b) Amount reclassified to offset earnings impact of liability hedged by cross currency swap Net deferred gains recorded in AOCI for the forward contracts that will mature in the next twelve months total $1.2 million, net of taxes. These gains are expected to be offset by anticipated losses in the value of the forecasted underlying hedged item. Amounts related to the cross currency swap expected to be reclassified from AOCI into income in the next twelve months total $0.4 million. Non-Designated Hedging Activities For a derivative instrument that has not been designated as an accounting hedge, the change in the fair value is recognized immediately in earnings. As of September 29, 2024, the Company had foreign currency forward contracts not designated as accounting hedges primarily in the following types and pairs (in millions): Contracts to Buy Contracts to Sell Currency Amount Currency Amount Canadian Dollars $ 327.6 U.S. Dollars US$ 243.9 Danish Krone Kr. 164.3 U.S. Dollars US$ 24.5 Great Britain Pounds £ 10.2 Euros € 12.0 Great Britain Pounds £ 115.7 U.S. Dollars US$ 152.4 Norwegian Krone kr 297.7 U.S. Dollars US$ 28.4 Swedish Krona kr 246.0 Euros € 21.8 Swedish Krona kr 754.7 U.S. Dollars US$ 74.2 U.S. Dollars US$ 10.9 Euros € 10.0 The preceding table includes non-designated hedges derived from terms contained in previously designated cash flow hedges. The gains and losses on these derivatives instruments which are not designated as accounting hedges are intended to, at a minimum, partially offset the transaction gains and losses recognized in earnings. The effect of derivative instruments not designated as accounting hedges recognized in other income and expense for the third quarter and nine months ended September 29, 2024 was income of $15.3 million and $3.2 million, respectively. The effect of derivative instruments not designated as accounting hedges in other income and expense for the third quarter and nine months ended October 1, 2023 was expense of $12.9 million and $3.1 million, respectively. The income or expense was largely offset by losses or gains in the value of the underlying hedged item excluding the impact of forward points. Fair Value of Derivative Financial Instruments The fair values of the Company’s derivative instruments are presented below. All fair values for these derivative instruments were measured using Level 2 inputs in the fair value hierarchy (in millions): Asset/(Liability) Derivative Instruments Balance sheet location September 29, 2024 December 31, 2023 Derivatives designated as hedging instruments: Cash flow forward contracts Other current assets $ 1.3 $ 3.7 Cash flow forward contracts Other non-current assets 0.4 2.4 Currency / interest rate contracts Other current assets 0.3 0.1 Currency / interest rate contracts Other current liabilities (24.2) (21.3) Total derivatives designated as hedging instruments (22.2) (15.1) Derivatives not designated as hedging instruments: Non-designated forward contracts Other current assets 5.2 14.2 Non-designated forward contracts Accrued liabilities (2.6) (3.2) Total derivatives not designated as hedging instruments 2.6 11.0 Total derivative instruments, net $ (19.6) $ (4.1)

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Trade Compliance Matters The Company has made voluntary disclosures to the U.S. Department of State and the U.S. Department of Commerce, including to the Bureau of Industry and Security (“BIS”) with respect to Teledyne FLIR shipments of products from non-U.S. jurisdictions which were not licensed due to an incorrect de minimis calculation methodology under the Export Administration Regulations. The Company has also made voluntary disclosures to export authorities in jurisdictions outside the U.S. for certain potential violations of local export laws. At this time, based on available information, we are unable to reasonably estimate the time it may take to resolve these matters or the amount or range of potential loss, penalty or other government action, if any, that may be incurred in connection with these matters. However, an unfavorable outcome could result in substantial fines and penalties or loss or suspension of export privileges or of particular authorizations that could be material to the Company’s financial position, results of operations or cash flows in and following the period in which such outcome becomes estimable or known. Environmental Remediation Obligations At September 29, 2024, the Company’s reserves for environmental remediation obligations totaled $6.7 million, of which $3.0 million is included in current accrued liabilities. At December 31, 2023, the Company’s reserves for environmental remediation obligations totaled $5.4 million. The Company evaluates whether it may be able to recover a portion of future costs for environmental liabilities from its insurance carriers and from third parties. The timing of expenditures depends on a number of factors that vary by site, including the nature and extent of contamination, the number of potentially responsible parties, the timing of regulatory approvals, the complexity of the investigation and remediation, and the standards for remediation. The Company expects that it will pay the amounts recorded over many years and will complete remediation of all sites with which it has been identified in up to 30 years. Legal Matters The Company is working to resolve a civil investigation by the U.S. Department of Justice relating to an ejection seat sequencer program and deliveries to the U.S. Government between 2006 and 2018. A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, contracts, employment and employment benefits. While the outcome of litigation, claims, proceedings and investigations cannot be predicted with certainty, and some of these matters may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial condition.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with generally accepted accounting principles in the United States (“GAAP”) as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (“2023 Form 10-K”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of September 29, 2024 and the consolidated results of operations, consolidated comprehensive income (loss) and consolidated cash flows for the third quarter and nine months ended September 29, 2024. The results of operations and cash flows for the periods ended September 29, 2024 and cash flows for the nine months ended September 29, 2024 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year.
Recent Accounting Standards	Recent Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard requires a public entity to disclose significant segment expenses and other segment items on an interim and annual basis. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements.
