In discussing financial results for the quarters and years ended December 31, 2025 and 2024 in this press release, the Company refers to certain financial measures that are adjusted from the financial results prepared in accordance with United States generally accepted accounting principles (“GAAP”). When referring to non-GAAP measures, the Company refers to them as “Adjusted.” See “Use of Non-GAAP Financial Measures” for additional information. A tabular reconciliation of financial measures prepared in accordance with GAAP to the non-GAAP financial measures is included at the end of this press release.
In some instances, the Company refers to changes in net sales, gross profit, earnings from operations and Adjusted earnings from operations on a consolidated basis and in North America, EMEA and APAC excluding the effects of fluctuating foreign currency exchange rates. In addition, the Company refers to changes in Adjusted diluted earnings per share on a consolidated basis excluding the effects of fluctuating foreign currency exchange rates. These are also considered to be non-GAAP measures. The Company believes providing this information excluding the effects of fluctuating foreign currency exchange rates provides valuable supplemental information to investors regarding its underlying business and results of operations, consistent with how the Company and its management evaluate the Company’s performance. In computing these changes and percentages, the Company compares the current year amount as translated into U.S. dollars under the applicable accounting standards to the prior year amount in local currency translated into U.S. dollars utilizing the weighted average translation rate for the current period. The performance measures excluding the effects of fluctuating foreign currency exchange rates should not be considered a substitute for, or superior to, the measures of financial performance prepared in accordance with GAAP.
The tax effect of Adjusted amounts referenced herein were computed using the statutory tax rate for the taxing jurisdictions in the operating segment in which the related expenses were recorded, adjusted for the effects of valuation allowances on net operating losses in certain jurisdictions.

GUIDANCE
For the full year 2026, including stock-based compensation expense, we expect Adjusted diluted earnings per share to be between $10.10 and $10.60. Beginning in 2026, our adjusted guidance will exclude stock-based compensation expense. On this basis, we expect our Adjusted diluted earnings per share will be between $11.00 to $11.50. This represents 5% growth at the midpoint compared to the 2025 Adjusted diluted EPS of $10.75, excluding stock-based compensation expense. We expect gross profit to be in the low single digits and expect that our gross margin will be approximately 21%.
This outlook assumes:
•interest and other expenses of approximately $85 million;
•an effective tax rate of 25.5% to 26.5% for the full year;
•capital expenditures between approximately $20 million and $30 million;
•an average share count for the full year of approximately 31.0 million shares.
This outlook excludes acquisition-related intangibles amortization expense of approximately $83.4 million, excludes non-cash stock based compensation expense and assumes no acquisition or integration related expenses, transformation or severance and restructuring expenses, net, no significant change in our debt instruments, and no significant change in the macroeconomic environment, whether due to tariffs or otherwise. Due to the inherent difficulty of forecasting some of these types of expenses, which impact net earnings, diluted earnings per share and selling and administrative expenses, the Company is unable to reasonably estimate the impact of such expenses, if any, to net earnings, diluted earnings per share and selling and administrative expenses. Accordingly, the Company is unable to provide a reconciliation of GAAP to non-GAAP diluted earnings per share for the full year 2026 forecast.
