Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Trade Compliance Matters The Company has made voluntary disclosures for certain potential violations of trade compliance laws to applicable U.S. Government authorities, including the U.S. Department of State and the U.S. Department of Commerce. The Company has also made voluntary disclosures to authorities in jurisdictions outside the United States for certain potential violations of local export and import laws. The Company accrues amounts associated with potential violations to the extent a loss, penalty or other government action becomes probable and can be reasonably estimated. 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. In February 2026, Teledyne FLIR LLC, together with certain of its legacy affiliates, reached a settlement agreement with the U.S. Department of Commerce’s Bureau of Industry and Security (BIS), concerning alleged export control compliance issues and subsequently paid a civil penalty of $1.0 million. These matters largely relate to historical conduct at FLIR Systems, Inc., which was acquired by Teledyne in May 2021. There were 19 proposed charges of alleged export violations, including inaccurate application of the BIS “de minimis” rule to foreign-produced products exported from abroad, failure of an affiliate in China to maintain the required records, and several export shipments to an address in Hong Kong on the BIS Entity List that were not identified by the screening software used by the company. The settlement amount reflects that these matters were voluntarily disclosed and that Teledyne cooperated fully with the government’s review and worked to enhance Teledyne FLIR’s export compliance program since the acquisition. Environmental Remediation Obligations At March 29, 2026, the Company’s reserves for environmental remediation obligations totaled $5.9 million, of which $3.0 million is included in current accrued liabilities. At December 28, 2025, the Company’s reserves for environmental remediation obligations totaled $6.0 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. Other Claims and Legal Matters In December 2025, Teledyne RISI, Inc. d/b/a Teledyne Electronic Safety Products (“TESP”) reached a final settlement agreement with the U.S. Department of Justice, on behalf of the Department of the Air Force and the Department of the Navy, regarding a civil false claims investigation relating to certain electronic modules manufactured between November 2011 and June 2012 for an ejection seat sequencer program. By entering a negotiated settlement, which included the payment by TESP of $1.5 million, TESP admitted no wrongdoing and sought to avoid the costs and expense of potential protracted litigation. Various claims (whether based on U.S. Government or Company audits and investigations or otherwise) may be asserted against the Company related to its U.S. Government contract work, including claims based on business practices and cost classifications and actions under the False Claims Act. Although such claims are generally resolved by detailed fact-finding and negotiation, on those occasions when they are not so resolved, civil or criminal legal or administrative proceedings may ensue. Depending on the circumstances and the outcome, such proceedings could result in fines, penalties, compensatory and treble damages or the cancellation or suspension of payments under one or more U.S. Government contracts. Under government regulations, a company, or one or more of its operating divisions or units, can also be suspended or debarred from government contracts based on the results of investigations. However, although the outcome of these matters cannot be predicted with certainty, management does not believe there is any audit, review or investigation currently pending against the Company of which management has knowledge that is likely to result in suspension or debarment of the Company, or that is otherwise likely to have a material adverse effect on the Company’s financial condition or liquidity, although the resolution in any reporting period of one or more of these matters could have a material adverse effect on the Company’s results of operations for that period. 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, commercial contracts, employment and employee benefits. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings 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.
