Dropped from FY2024

The new Presidential administration has announced plans to significantly cut federal spending and the size of the federal government and has taken steps to reduce and reorganize the federal workforce at many agencies.

Dropped from FY2024

It is unclear how such cuts, if implemented, could impact our current and future business with the U.S. government.

Dropped from FY2024

If cuts to government personnel lead to staff shortages or disorganization at certain federal agencies, we may experience delays in obtaining contract awards or payments, the loss of current or future contracts, or delays in obtaining necessary permits, licenses or registrations.

New in FY2025

Overview

New in FY2025

The global trade environment continues to be highly dynamic, including new potential tariffs and retaliatory tariffs, and a number of the tariffs remain in effect.

New in FY2025

There have been continuing significant tariffs and trade sanctions between the United States and China.

New in FY2025

China has also restricted the export of certain rare earth minerals that we use in our products, which could disrupt the supply chain for these minerals and components made from these materials.

New in FY2025

Tariffs, trade restrictions and retaliatory measures could result in revenue reductions, cost increases on material used in our products or significant production delays, which could adversely affect our business, financial condition, operational results and cash flows.

New in FY2025

Our manufacturing facilities span across many countries which helps us mitigate the impact of certain tariffs and trade restrictions.

New in FY2025

Also, consistent with our strategy, we continually optimize our operations and take measures to contain costs to reduce the impact from tariffs.

New in FY2025

We may also implement additional pricing actions to mitigate the impact of these tariffs.

New in FY2025

We have been working to minimize potential delivery delays and shortages of components and raw materials needed for certain products we manufacture.

New in FY2025

To date, we believe our strategies have helped minimize our exposure to these conditions.

New in FY2025

It is unclear how the recent U.S. Supreme Court ruling invalidating certain tariffs will impact our exposure to tariffs or our strategy with respect to tariffs going forward.

New in FY2025

U.S. Government shutdowns could negatively impact our businesses.

New in FY2025

Previous U.S. Government shutdowns have resulted in delays in anticipated contract awards, issuances of export licenses, shipments and payments of invoices for several of our businesses.

New in FY2025

We try to reduce this potential volatility in reported earnings primarily through derivative instruments and hedging activities.

New in FY2025

During 2026, we plan to invest approximately $150 million in capital expenditures, principally to upgrade facilities and manufacturing equipment as well as to support internal growth initiatives.

New in FY2025

As part of a continuing effort to reduce costs and improve operating performance, we continue to take actions to consolidate and relocate certain facilities, rationalize products and reduce headcount across various businesses, reducing our exposure to weaker end markets.

New in FY2025

We continue to seek cost reductions in our businesses.

New in FY2025

Subsequent to the end of the year, we have completed one acquisition which will be included within the Instrumentation segment.

Dropped from FY2024

Research and development expense and the research and development expense percentage for 2024 decreased 27.3% compared with 2023, with the decrease driven primarily by the completion of certain unmanned air systems product development activities in 2023 that moved to commercialization in early 2024, FLIR integration-related cost-reduction efforts implemented in the second half of 2023 and a larger percentage of labor focused on customer-funded research and development projects in 2024 as compared to 2023.

Our evaluation of internal control over financial reporting excluded the internal control activities of the Optical Systems (“OS”) business and Advanced Electronics Systems (“AES”) business (collectively, “OS and AES businesses”, or “Qioptiq”) which we acquired in February 2025.

New in FY2025

We have included the financial results of this acquisition in our consolidated financial statements from the date of acquisition.

New in FY2025

Total assets (excluding goodwill and intangible assets) and total net sales subject to Qioptiq’s internal control over financial reporting represented approximately 1% and 3% of our consolidated total assets and total net sales as of and for the fiscal year ended December 28, 2025, respectively.

New in FY2025

We did not assess the effectiveness of internal control over financial reporting at this newly acquired entity due to the insufficient time between the date acquired and year end and the complexity associated with assessing internal controls during integration efforts making the process impractical.

Goodwill – FLIR Reporting Unit - Refer to Notes 2, 4, and 6 to the financial statements

Dropped from FY2024

*Critical Audit Matter Description*

Dropped from FY2024

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to the respective carrying value.

Dropped from FY2024

For goodwill impairment testing using the quantitative approach, the Company used a combination of the discounted cash flow approach and the market approach to estimate fair value of the FLIR reporting unit.

Dropped from FY2024

The Company’s goodwill balance was $7,990.5 million as of December 29, 2024, of which $5,827.1 million was allocated to the FLIR reporting unit.

Dropped from FY2024

The application of the discounted cash flow model requires management to make significant estimates and assumptions related to projected revenues and the selected discount rate.

Dropped from FY2024

Given the significant estimates and assumptions made by management to estimate the fair value of the FLIR reporting unit and the difference between the FLIR reporting unit’s fair value and carrying value, performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions, specifically related to the projected revenues and selected discount rate, required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

Dropped from FY2024

*How the Critical Audit Matter Was Addressed in the Audit*

Dropped from FY2024

- We performed a sensitivity analysis by varying projected revenue assumptions.

- With the assistance of our fair value specialists, we performed an analysis comparing applicable industry forecasted long-term revenue growth rate to management’s projected revenues used within the valuation model.

Dropped from FY2024

- With the assistance of our fair value specialists, we evaluated the reasonableness of the discount rate by developing a range of independent estimates and comparing those to the discount rate selected by management.

Dropped from FY2024

Our audit procedures related to (1) revenue projections and (2) the selection of the discount rate used to estimate the fair value of the indefinite-lived trademarks included the following, among others:

Dropped from FY2024
