Non-GAAP financial measures:

This earnings release includes the following financial measures that are not presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”):

(1) Adjusted operating margin, which the Company defines as operating margin excluding acquisition-related amortization of intangible assets and discrete items, which are acquisition and related integration costs, gains or losses on the sale or disposal of property, plant and equipment, restructuring, severance, impairment and other related costs, UTIS fire and recovery charges, (income) costs associated with terminated merger, and the related income tax effect on these items (collectively, “discrete items”);

(2) Adjusted net income, which the Company defines as net income excluding amortization of acquisition intangible assets, pension settlement charges and discrete items;

(3) Adjusted earnings per diluted share, which the Company defines as earnings per diluted share excluding amortization of acquisition intangible assets, pension settlement charges and discrete items divided by adjusted weighted average shares outstanding - diluted;

(4) Adjusted EBITDA, which the Company defines as net income excluding interest expense, net, income tax expense, depreciation and amortization, stock-based compensation expense, pension settlement charges and discrete items;

(5) Adjusted EBITDA Margin, which the Company defines as the percentage that results from dividing Adjusted EBITDA by total net sales;

(6) Free cash flow, which the Company defines as net cash provided by operating activities less non-acquisition capital expenditures.

Management believes adjusted operating margin, adjusted net income, adjusted earnings per diluted share, adjusted EBITDA and adjusted EBITDA margin are useful to investors because they allow for comparison to the Company’s performance in prior periods without the effect of items that, by their nature, tend to obscure the Company’s core operating results due to potential variability across periods based on the timing, frequency and magnitude of such items. As a result, management believes that these measures enhance the ability of investors to analyze trends in the Company’s business and evaluate the Company’s performance relative to peer companies. Management also believes free cash flow is useful to investors as an additional way of viewing the Company's liquidity and provides a more complete understanding of factors and trends affecting the Company's cash flows. However, non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation from, or as alternatives to, financial measures prepared in accordance with GAAP. In addition, these non-GAAP financial measures may differ from, and should not be compared to, similarly named measures used by other companies. Reconciliations of the differences between these non-GAAP financial measures and their most directly comparable financial measures calculated in accordance with GAAP are set forth below.
