Safe Harbor / Non-GAAP Financial Measures SAFE HARBOR / FORWARD LOOKING STATEMENT This presentation contains forward-looking information and other forward-looking statements within the meaning of applicable Canadian and/or U.S. securities laws, including our long term growth framework, discussion of housing and other markets, and the effects of our restructuring and strategic initiatives. When used in this presentation, such forward-looking statements may be identified by the use of such words as "may," "might," "could," "will," "would," "should," "expect," "believes," "outlook," "predict," "forecast," "objective," "remain," "anticipate," "estimate," "potential," "continue," "plan," "project," "targeting," or the negative of these terms or other similar terminology. Forward-looking statements involve significant known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of Masonite, or industry results, to be materially different from any future plans, goals, targets, objectives, results, performance or achievements expressed or implied by such forward-looking statements. As a result, such forward-looking statements should not be read as guarantees of future performance or results, should not be unduly relied upon, and will not necessarily be accurate indications of whether or not such results will be achieved. Factors that could cause actual results to differ materially from the results discussed in the forward-looking statements include, but are not limited to, downward trends in our end markets and in economic conditions; reduced levels of residential new construction; residential repair, renovation and remodeling; and non-residential building construction activity due to increases in mortgage rates, changes in mortgage interest deductions and related tax changes and reduced availability of financing; competition; the continued success of, and our ability to maintain relationships with, certain key customers in light of customer concentration and consolidation; new tariffs and evolving trade policy between the United States and other countries, including China; increases in prices of raw materials and fuel; increases in labor costs, the availability of labor, or labor relations (i.e., disruptions, strikes or work stoppages); our ability to manage our operations including anticipating demand for our products, managing disruptions in our operations, managing manufacturing realignments (including related restructuring charges), managing customer credit risk and successful integration of acquisitions; the continuous operation of our information technology and enterprise resource planning systems and management of potential cyber security threats and attacks; our ability to generate sufficient cash flows to fund our capital expenditure requirements, to meet our pension obligations, and to meet our debt service obligations, including our obligations under our senior notes and our ABL Facility; political, economic and other risks that arise from operating a multinational business; uncertainty relating to the United Kingdom's anticipated exit from the European Union; fluctuating exchange and interest rates; our ability to innovate and keep pace with technological developments; product liability claims and product recalls; retention of key management personnel; environmental and other government regulations, including the FCPA, and any changes in such regulations; and limitations on operating our business as a result of covenant restrictions under our existing and future indebtedness, including our senior notes and our ABL Facility. NON-GAAP FINANCIAL MEASURES Our management reviews net sales and Adjusted EBITDA (as defined below) to evaluate segment performance and allocate resources. Net assets are not allocated to the reportable segments. Adjusted EBITDA is a non-GAAP financial measure which does not have a standardized meaning under GAAP and is unlikely to be comparable to similar measures used by other companies. Adjusted EBITDA should not be considered as an alternative to either net income or operating cash flows determined in accordance with GAAP. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management's discretionary use, as it does not include certain cash requirements such as interest payments, tax payments and debt service requirements. Adjusted EBITDA is defined as net income attributable to Masonite adjusted to exclude the following items: depreciation; amortization; share based compensation expense; loss (gain) on disposal of property, plant and equipment; registration and listing fees; restructuring costs; asset impairment; loss (gain) on disposal of subsidiaries; interest expense (income), net; loss on extinguishment of debt; other expense (income), net; income tax expense (benefit); loss (income) from discontinued operations, net of tax; and net income (loss) attributable to non-controlling interest. This definition of Adjusted EBITDA differs from the definitions of EBITDA contained in the indentures governing the 2026 Notes and 2023 Notes and the credit agreement governing the ABL Facility. Adjusted EBITDA, as calculated under our ABL Facility or senior notes would also include, among other things, additional add-backs for amounts related to: cost savings projected by us in good faith to be realized as a result of actions taken or expected to be taken prior to or during the relevant period; fees and expenses in connection with certain plant closures and layoffs; and the amount of any restructuring charges, integration costs or other business optimization expenses or reserve deducted in the relevant period in computing consolidated net income, including any one-time costs incurred in connection with acquisitions. Adjusted EBITDA is used to evaluate and compare the performance of the segments and it is one of the primary measures used to determine employee incentive compensation. Intersegment transfers are negotiated on an arm's length basis, using market prices. We believe that Adjusted EBITDA, from an operations standpoint, provides an appropriate way to measure and assess segment performance. Our management team has established the practice of reviewing the performance of each segment based on the measures of net sales and Adjusted EBITDA. We believe that Adjusted EBITDA is useful to users of the consolidated financial statements because it provides the same information that we use internally to evaluate and compare the performance of the segments and it is one of the primary measures used to determine employee incentive compensation. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by Net Sales. Management believes this measure provides supplemental information on how successfully we operate our business. Adjusted EPS is diluted earnings per common share attributable to Masonite (EPS) less restructuring costs, asset impairment charges, loss (gain) on disposal of subsidiaries, loss on extinguishment of debt and other items, if any, that do not relate to Masonite's underlying business performance (each net of related tax expense (benefit)). In the fourth quarter of 2018, we changed the definition of Adjusted EPS to exclude restructuring charges and related tax impacts. This change had no impact to Adjusted EPS for the three months ended April 1, 2018. Management uses this measure to evaluate the overall performance of the Company and believes this measure provides investors with helpful supplemental information regarding the underlying performance of the Company from period to period. This measure may be inconsistent with similar measures presented by other companies. 2 masonite.com
