Forward-Looking Statements

This presentation contains “forward-looking statements” within the meaning of the Federal Private Securities Litigation Reform Act of 1995. Forward-

looking statements may include, but are not limited to, statements relating to our 2016 Adjusted EBITDA outlook. Some of the forward-looking

statements can be identified by the use of terms such as “may,” “intend,” “might,” “will,” “should,” “could,” “would,” “expect,” “believe,” “estimate,”

“anticipate,” “predict,” “project,” “potential,” or the negative of these terms, and similar expressions. You should be aware that these forward-looking

statements are subject to risks and uncertainties that are beyond our control. Further, any forward-looking statement speaks only as of the date on

which it is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it

is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. New factors emerge from time to time that may cause our

business not to develop as we expect, and it is not possible for us to predict all of them. Factors that may cause actual results to differ materially from

those expressed or implied by the forward-looking statements include, but are not limited to, the following: cyclicality in residential and commercial

construction markets; general economic and financial conditions; weather conditions, seasonality and availability of water to end-users; laws and

government regulations applicable to our business that could negatively impact demand for our products; public perceptions that our products and

services are not environmentally friendly; competitive industry pressures; product shortages and the loss of key suppliers; product price fluctuations;

inventory management risks; ability to implement our business strategies and achieve our growth objectives; acquisition and integration risks;

increased operating costs; and other risks, as indicated in our final prospectus filed pursuant to Rule 424(b)(4) under the Securities Act of 1933, as

amended, filed with the U.S. Securities and Exchange Commission on May 12, 2016 (Registration No. 333-206444).

Non-GAAP Financial Information

This presentation includes certain financial information, not prepared in accordance with U.S. GAAP. Because not all companies calculate non-GAAP

financial information identically (or at all), the presentations herein may not be comparable to other similarly titled measures used by other companies.

Further, these measures should not be considered substitutes for the information contained in the historical financial information of the Company

prepared in accordance with U.S. GAAP that is set forth herein.

We present Adjusted EBITDA in order to evaluate the operating performance and efficiency of our business. Adjusted EBITDA represents EBITDA as

further adjusted for items permitted under the covenants of our credit facilities. EBITDA represents our net income (loss) plus the sum of interest

expense, net of interest income and excluding amortization of debt discount, income tax expense (benefit), depreciation, and amortization. Adjusted

EBITDA is further adjusted for stock-based compensation expense, related party advisory fees, loss (gain) on sale of assets and other non-cash

items, other non-recurring (income) and loss. Adjusted EBITDA does not include pre-acquisition Adjusted EBITDA. Adjusted EBITDA is not a measure

of our liquidity or financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other

performance measures derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. The

use of Adjusted EBITDA instead of net income has limitations as an analytical tool. Because not all companies use identical calculations, our

presentation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies, limiting its usefulness as a

comparative measure. Net debt and capital leases is defined as long-term debt and capital lease obligations less cash and cash-equivalents.
