Safe Harbor / Non-GAAP Financial Measure

SAFE HARBOR / FORWARD LOOKING STATEMENT This investor presentation contains forward-looking information and other forward-looking statements within the meaning of applicable Canadian and/or U.S. securities laws, including our

discussion of improvements in the housing market and related markets and the effects of our pricing and other strategies. When used in this Investor 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, our ability to successfully implement our business strategy; general economic, market and business conditions; levels of residential new construction, residential

repair, renovation and remodeling and non-residential building construction activity; competition; our ability to manage our operations including integrating our recent acquisitions and

companies or assets we acquire in the future; our ability to generate sufficient cash flows to fund our capital expenditure requirements and to meet our debt service obligations, including

our obligations under our senior notes and our senior secured asset-backed credit facility; labor relations (i.e., disruptions, strikes or work stoppages), labor costs, and availability of labor;

increases in the costs of raw materials or any shortage in supplies; our ability to keep pace with technological developments; the actions by, and the continued success of, certain key

customers; our ability to maintain relationships with certain customers; new contractual commitments; our ability to generate the benefits of our restructuring activities; retention of key

management personnel; environmental and other government regulations; limitations on operating our business as a result of covenant restrictions under our existing and future

indebtedness, including our senior notes and senior secured asset-based credit facility; and other factors publicly disclosed by the company from time to time.

NON-GAAP FINANCIAL MEASURE Adjusted EBITDA is a measure used by management to measure operating performance. Beginning in the first quarter of 2015, we revised our calculation of Adjusted EBITDA to

separately exclude loss on extinguishment of debt, which would be a component of other expense (income), net, but is separately stated due to its magnitude. Furthermore, in the third

quarter of 2015, we revised our calculation of Adjusted EBITDA to separately exclude loss (gain) on disposal of subsidiaries. The revisions to this definition had no impact on our reported

Adjusted EBITDA for the three or nine months ended September 28, 2014. As revised, Adjusted EBITDA is defined as net income (loss) attributable to Masonite plus depreciation,

amortization, restructuring costs, loss (gain) on sale of property, plant and equipment, asset impairment, loss (gain) on disposal of subsidiaries, registration and listing fees, interest

expense, net, loss on extinguishment of debt, other expense (income), net, income tax expense (benefit), loss (income) from discontinued operations, net of tax, net income attributable to

non-controlling interest and share based compensation expense. Adjusted EBITDA is not a measure of financial condition or profitability under GAAP, and should not be considered as an

alternative to (i) net income (loss) or net income (loss) attributable to Masonite determined in accordance with GAAP or (ii) operating cash flow 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. We believe that the inclusion of Adjusted EBITDA in this press release is appropriate to provide additional information to investors

about our operating performance. Not all companies use identical calculations, and as a result, this presentation of Adjusted EBITDA may not be comparable to other similarly titled

measures of other companies. Moreover, Adjusted EBITDA as presented for financial reporting purposes herein, although similar, is not the same as similar terms in the applicable

covenants in our ABL Facility or our senior notes. 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. A reconciliation of Adjusted EBITDA to net income (loss)

attributable to Masonite for the periods indicated is set forth in the appendix to this presentation.
