Financial Guidance

Adjusted EBITDA is a non-GAAP financial measure. The Company is not able to reconcile the Adjusted EBITDA outlook to the most directly comparable GAAP measure, forecasted net income, on a forward-looking basis without unreasonable efforts. This is due to the inherent difficulty in forecasting certain items that are necessary for such reconciliation, including (without limitation) non-cash stock-based compensation expense, integration-related expenses, restructuring and transformation-related costs, impairment charges, and the related tax effects of these items. These items are uncertain, depend on various factors outside of the Company’s control, and could be material to the Company’s results calculated in accordance with GAAP. Accordingly, the Company is unable to provide a probable significance of the unavailable information, but such unavailable information could have a potentially significant impact on the Company’s actual net income for fiscal year 2027.

Statement regarding use of non-GAAP financial measures

This press release includes certain non-GAAP financial measures, which management believes are useful to investors, securities analysts and other interested parties in evaluating the Company’s operating performance and financial condition. These non-GAAP measures provide additional insight into the Company’s core business operations by excluding items that may not be indicative of, or are unrelated to, the Company’s ongoing operational performance, thereby enhancing comparability between periods and with peer companies. Management uses Adjusted EBITDA as a key profitability measure. This is a non-GAAP measure that represents EBITDA before certain items that impact comparison of the performance of our business, either period-over-period or with other businesses. Adjusted EBITDA Margin is Adjusted EBITDA for a particular period expressed as a percentage of revenues for that period.

Management uses Adjusted Gross Profit as an additional measure of profitability. Adjusted Gross Profit is a non-GAAP measure that represents Gross Profit before certain items that impact comparison of the performance of our business, either period-over-period or with other businesses. Adjusted Gross Margin is Adjusted Gross Profit for a particular period expressed as a percentage of revenues for that period.

Management uses Adjusted Operating Income (Loss) as an additional measure of profitability. Adjusted Operating Income (Loss) is a non-GAAP measure that represents Operating Income (Loss) before certain items that impact comparison of the performance of our business, either period-over-period or with other businesses. Adjusted Operating Margin is Adjusted Operating Income for a particular period expressed as a percentage of revenues for that period.

Management uses Adjusted Net Income (Loss) as an additional measure of profitability. Adjusted Net Income (Loss) is a non-GAAP measure that represents Net Income (Loss) before certain items that impact comparison of the performance of our business, either period-over-period or with other businesses. Adjusted Earnings Per Share is Adjusted Net Income for a particular period divided by diluted weighted average shares outstanding for that period.

Core revenue growth is a non-GAAP measure that represents change in net sales for the period excluding the effects of foreign currency translation rates and the impacts of acquisitions and discontinued product lines, where applicable. Core revenue growth is presented to allow for a meaningful comparison of year-over-year performance without the volatility caused by foreign currency translation rates, or the incomparability that would be caused by the impact of an acquisition, disposal or product line discontinuation.
