Teledyne Technologies (TDY) 425Business combination disclosure

Exhibit 99.1

Teledyne and FLIR have entered into a definitive agreement under which Teledyne will acquire FLIR in a cash and stock transaction valued at approximately $8.0 billion. Under the terms of the agreement, FLIR stockholders will receive $28.00 per share in cash and 0.0718 shares of Teledyne common stock for each FLIR share, which implied a total purchase price of $56.00 per FLIR share based on Teledyne’s 5-day volume weighted average price as of December 31, 2020. The transaction is expected to close on May 13, 2021, subject to the receipt of required remaining regulatory approvals, including approvals of Teledyne and FLIR stockholders and other customary closing conditions. In the quarter, Teledyne completed various financing activities related to the pending acquisition of FLIR and incurred related interest expense totaling $33.1 million. These activities included entering into a $4.5 billion short term stand-by bridge facility on January 4, 2021, as required by the definitive agreement, resulting in interest expense of $17.2 million. In addition, on March 17, 2021, Teledyne called $493.3 million of existing fixed rate senior notes and incurred debt extinguishment expenses of $13.4 million. On March 22, 2021, Teledyne completed all permanent financing for the pending acquisition of FLIR. The permanent financing consists of $3.0 billion investment-grade bonds (the “Notes”), including $300.0 million

aggregate principal amount of 0.65% Notes due 2023, $450.0 million aggregate principal amount of 0.95% Notes due 2024, $450.0 million aggregate principal amount of 1.60% Notes due 2026, $700.0 million aggregate principal amount of 2.25% Notes due 2028 and $1.1 billion aggregate principal amount of 2.75% Notes due 2031. Given the permanent financing, together with certain continuing debt, Teledyne expects its weighted average borrowing cost to be less than two percent upon closing the acquisition. The interest expense incurred in the quarter associated with the $3.0 billion Notes offering related to the pending FLIR acquisition totaled $2.5 million. Previously on March 4, 2021, Teledyne entered into a $1.0 billion Term Loan Credit Agreement and Amended and Restated Credit Agreement with capacity of $1.15 billion both maturing on March 4, 2026. As a result of the completion of the permanent debt financing, on March 22, 2021 Teledyne terminated the $4.5 billion stand-by bridge facility. Teledyne intends to use the proceeds from the Notes together with the proceeds from the $1.0 billion term loan and cash on hand to pay the cash portion of the consideration for the FLIR acquisition and refinance certain existing debt.

At April 4, 2021, total debt was $3,243.3 million, compared with total debt of $778.5 million at January 3, 2021. The debt balance at April 4, 2021, includes the debt incurred to fund the cash portion of the consideration for the FLIR acquisition. At April 4, 2021, $125.0 million was outstanding under the $750.0 million credit facility with available borrowing capacity under the facility, which is reduced by borrowings and certain outstanding letters of credit, of $616.0 million.

Forward-Looking Statements Cautionary Notice

The forward-looking statements contained herein may include statements about the expected effects on Teledyne of the proposed acquisition of FLIR and related financing, the anticipated timing and scope of the proposed transaction, anticipated earnings enhancements, estimated cost savings and other synergies related to the proposed transaction, costs to be incurred in achieving synergies, anticipated capital expenditures and product developments, and other strategic options. Forward-looking statements generally are accompanied by words such as “projects”, “intends”, “expects”, “anticipates”, “targets”, “estimates”, “will” and words of similar import that convey the uncertainty of future events or outcomes. All statements made in this communication that are not historical in nature should be considered forward-looking. By its nature, forward-looking information is not a guarantee of future performance or results and involves risks and uncertainties because it relates to events and depends on circumstances that will occur in the future.

Actual results could differ materially from these forward-looking statements. Many factors could change anticipated results, including ongoing challenges and uncertainties posed by the COVID-19 pandemic for businesses and governments around the world; the occurrence of any event, change or other circumstances that could give rise to the right of Teledyne or FLIR or both to terminate the Merger Agreement; the outcome of any legal proceedings that may be instituted against Teledyne or FLIR in connection with the Merger Agreement; the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction) or stockholder approvals or to satisfy any of the other conditions to the proposed transaction on a timely basis or at all; the inability to complete the acquisition and integration of FLIR successfully, to retain customers and key employees and to achieve operating synergies, including the possibility that the anticipated benefits of the proposed transaction are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Teledyne and FLIR do business; the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the parties’ ability to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; dilution related to the issuance of Teledyne stock in the acquisition to the holders of FLIR stock, which will result in Teledyne stockholders having lower ownership and voting interests in Teledyne than they currently have and exercising less influence over management; changes in relevant tax and other laws; the inability to develop and market new competitive products; inherent uncertainties involved in the estimates and judgments used in the preparation of financial statements and the providing of estimates of financial measures, in accordance with U.S. GAAP and related standards; operating results of FLIR being lower than anticipated; disruptions in the global economy; the spread of the COVID-19 virus resulting in production, supply, contractual and other disruptions, including facility closures and furloughs and travel restrictions; customer and supplier bankruptcies; changes in demand for products sold to the defense electronics, instrumentation, digital imaging, energy exploration and production, commercial aviation, semiconductor and communications markets; funding, continuation and award of government programs; cuts to defense spending resulting from existing and future deficit reduction measures or changes to U.S. and foreign government spending and budget priorities triggered by

the COVID-19 pandemic; impacts from the United Kingdom’s exit from the European Union; uncertainties related to the policies of the new U.S. Presidential Administration; the imposition and expansion of, and responses to, trade sanctions and tariffs; escalating economic and diplomatic tension between China and the United States; and threats to the security of our confidential and proprietary information, including cyber security threats. Lower oil and natural gas prices, as well as instability in the Middle East or other oil producing regions, and new regulations or restrictions relating to energy production, including with respect to hydraulic fracturing, could further negatively affect our businesses that supply the oil and gas industry. Continued weakness in the commercial aerospace industry will negatively affect the markets of our commercial aviation businesses. In addition, financial market fluctuations affect the value of the company’s pension assets.

Changes in the policies of U.S. and foreign governments, including economic sanctions, could result, over time, in reductions or realignment in defense or other government spending and further changes in programs in which the company participates.

Additional factors that could cause results to differ materially from those described above can be found in Teledyne’s Annual Report on Form 10-K for the year ended January 3, 2021, and subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are on file with the SEC and available in the “Investors” section of Teledyne’s website, teledyne.com, under the heading “Investor Information” and in other documents Teledyne files with the SEC, and in FLIR’s Annual Report on Form 10-K for the year ended December 31, 2020, and subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are on file with the SEC and available on the “Investor Relations” page of FLIR’s website, flir.com, under the heading “Filings and Financials” and in other documents FLIR files with the SEC.

We report our financial results in accordance with GAAP. However, management believes that, in order to more fully understand our short-term and long-term financial and operational trends, investors may wish to consider the impact of certain items resulting from our pending acquisition of FLIR which have an infrequent or non-recurring impact on operations. Accordingly, we present non-GAAP financial measures as a supplement to the financial measures we present in accordance with GAAP. These non-GAAP financial measures provide management with additional means to understand and evaluate the operating results and trends in our ongoing business by adjusting for certain expenses and other items. Management believes these non-GAAP financial measures provide additional means of evaluating period-over-period operating performance. In addition, management understands that some investors and financial analysts find this information helpful in analyzing our financial and operational performance and comparing this performance to our peers and competitors. The company’s 2021 diluted earnings per common share guidance is also presented on a non-GAAP basis.

We use the term, “total debt”, a non-GAAP measure, to refer to the sum of GAAP current portion of long-term debt and other debt and GAAP long-term debt. We use the term “net debt” to refer to the difference between total debt less GAAP cash and cash equivalents. The company believes that this supplemental non-GAAP information is useful to assist management and the investment community in analyzing the company’s liquidity.

Management excludes the effect of each of the items identified below to arrive at the applicable non-GAAP financial measure referenced in the previous table for the reasons set forth below with respect to that item:
