Non-GAAP Financial Measures

This news release includes the following non-generally accepted accounting principles (“GAAP”) financial measures: "adjusted gross profit", "adjusted gross profit margin", “adjusted operating profit” and “adjusted operating profit margin” for total company and by segment; for total company only we additionally include: “adjusted net income;” “adjusted diluted EPS;” “earnings before interest, taxes, depreciation and amortization (“EBITDA”);" "EBITDA margin;" “adjusted EBITDA;” and "adjusted EBITDA margin". These non-GAAP financial measures are provided to enhance the reader's overall understanding of our current financial performance and prospects for the future. Specifically, management believes that these non-GAAP measures provide useful information to investors by excluding or adjusting items for amortization of acquired intangible assets, share-based payment expense, acquired profit in inventory, acquisition-related items, and special charges.

We also provide “free cash flow” (“FCF”) to enhance the reader’s understanding of our ability to generate additional cash from its business.

Management typically adjusts for these items for internal reviews of performance and uses the above non-GAAP measures for baseline comparative operational analysis, decision making and other activities. Management believes these non-GAAP measures provide greater comparability and enhanced visibility into our results of operations as well as comparability with many of its peers, especially those companies focused more on technology and software. Non-GAAP financial measures included in this news release should be considered in addition to, and not as a substitute for or superior to, results prepared in accordance with GAAP.

The most directly comparable GAAP measures for adjusted gross profit and adjusted gross profit margin for total company are “gross profit” and “gross profit margin,” respectively, which include the impact of acquired profit in inventory and tariff refunds. Adjusted gross profit margin is adjusted gross profit divided by net sales for total company and by segment. The most directly comparable GAAP measures for adjusted operating profit and adjusted operating profit margin for total company and by segment are “operating profit” and “operating profit margin,” respectively, which include the impact of amortization of acquired intangible assets, share-based payment expense, acquired profit in inventory, acquisition-related costs, special charges, and tariff refunds. Adjusted operating profit margin is adjusted operating profit divided by net sales for total company and by segment. The most directly comparable GAAP measures for adjusted net income and adjusted diluted EPS are “net income” and “diluted EPS,” respectively, which include the impact of amortization of acquired intangible assets, share-based payment expense, acquired profit in inventory, acquisition-related costs, special charges, and tariff refunds. Adjusted diluted EPS is adjusted net income divided by diluted weighted average shares outstanding. The most directly comparable GAAP measure for EBITDA is “net income”, which includes the impact of net interest expense, income taxes, depreciation and amortization of acquired intangible assets. EBITDA margin is EBITDA divided by net sales for total company. The most directly comparable GAAP measure for adjusted EBITDA is “net income”, which includes the impact of net interest expense, income taxes, depreciation, amortization of acquired intangible assets, share-based payment expense, acquired profit in

inventory, acquisition-related items, special charges, miscellaneous (income) expense, net, and tariff refunds. Adjusted EBITDA margin is adjusted EBITDA divided by net sales for total company. A reconciliation of each measure to the most directly comparable GAAP measure is available in this news release.

We define FCF as net cash provided by operating activities less purchases of property, plant and equipment. A calculation of this measure is available in this news release.

Our non-GAAP financial measures may not be comparable to similarly titled non-GAAP financial measures used by other companies, have limitations as an analytical tool, and should not be considered in isolation or as a substitute for GAAP financial measures. Our presentation of such measures, which may include adjustments to exclude unusual or non-recurring items, should not be construed as an inference that our future results will be unaffected by other unusual or non-recurring items.

Forward-Looking Information

This press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 (the “Act”). Forward-looking statements include, but are not limited to, statements that describe or relate to our plans, initiatives, projections, vision, goals, targets, commitments, expectations, objectives, prospects, strategies, or financial outlook, and the assumptions underlying or relating thereto. In some cases, we may use words such as “expect,” “believe,” “intend,” “anticipate,” “estimate,” “forecast,” “indicate,” “project,” “predict,” “plan,” “may,” “will,” “could,” “should,” “would,” “potential,” and words of similar meaning, as well as other words or expressions referencing future events, conditions, or circumstances, to identify forward-looking statements. We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Act. Forward-looking statements are not guarantees of future performance. Our forward-looking statements are based on our current beliefs, expectations, and assumptions, which may not prove to be accurate, and are subject to known and unknown risks and uncertainties, assumptions, and other important factors, many of which are outside of our control and any of which could cause our actual results to differ materially from those expressed or implied by the forward-looking statements. These risks and uncertainties are discussed in our filings with the U.S. Securities and Exchange Commission, including our most recent annual report on Form 10-K (including, but not limited to, the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations"), quarterly reports on Form 10-Q, and current reports on Form 8-K. Any forward-looking statement speaks only as of the date on which it is made. This press release is not comprehensive, and for that reason, should be read in conjunction with such filings. You are cautioned not to place undue reliance on any forward-looking statements. Except as required by law, we undertake no obligation to publicly update or release any revisions to these forward-looking statements to reflect any events or circumstances after the date of this press release or to reflect the occurrence of unanticipated events, whether as a result of new information, future events, or otherwise.
