Expected Second Fiscal Quarter 2017 Results

For the three months ended July 2, 2017, we expect net sales to be $605.0 million to $610.0 million, an increase of $91.6 million to $96.6 million, or 18% to 19%, as compared to net sales of $513.4 million for the three months ended July 3, 2016; net income to be $43.9 million to $44.4 million, an increase of $17.0 million to $17.5 million, as compared to net income of $26.9 million for the three months ended July 3, 2016; and Adjusted EBITDA to be $92.0 million to $92.5 million, an increase of $17.1 million to $17.6 million, as compared to Adjusted EBITDA of $74.9 million for the three months ended July 3, 2016. For the six months ended July 2, 2017, we expect net sales to be $940.0 million to $945.0 million, an increase of $98.1 million to $103.1 million, or 12%, as compared to net sales of $841.9 million for the six months ended July 3, 2016; net income to be $33.4 million to $33.9 million, an increase of $12.1 million to $12.6 million, as compared to net income of $21.3 million for the six months ended July 3, 2016; and Adjusted EBITDA to be $93.2 million to $93.7 million, an increase of $13.8 million to $14.3 million, as compared to Adjusted EBITDA of $79.4 million for the six months ended July 3, 2016. Our results in both the quarter and the first six months benefited from the strong sales growth and gross margin improvements achieved through our operational initiatives. Our net sales growth in both the quarter and first six months reflected the impact of acquisitions and positive organic sales growth. In addition, net sales growth for the three months ended July 2, 2017 reflected a return to normal spring weather patterns as compared to the early spring in 2016 when we experienced unusually strong organic daily sales growth in the first quarter and correspondingly weaker organic daily sales growth in the second quarter.

Our ongoing liquidity needs are expected to be funded by cash on hand, net cash provided by operating activities and, as required, borrowings under our asset-based loan facility. Our borrowing base capacity under our asset-based loan facility was approximately $127.5 million as of July 2, 2017 after giving effect to approximately $193.1 million of revolving credit loans under our asset-based loan facility, a $102.1 million increase from $91.0 million of revolving credit loans outstanding as of January 1, 2017, reflecting a seasonal increase in working capital and the completion of five acquisitions in the first half of the year.

The estimated results for the three and six months ended July 2, 2017 are preliminary, unaudited and subject to completion, reflect management’s current views and may change as a result of management’s review of results and other factors, including a wide variety of significant business, economic and competitive risks and uncertainties. Such preliminary results are subject to the closing of the second fiscal quarter of 2017 and finalization of financial and accounting procedures (which have yet to be performed) and should not be viewed as a substitute for full quarterly financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). We caution you that the estimates of net sales, net income (loss) and Adjusted EBITDA are forward-looking statements and are not guarantees of future

performance or outcomes and that actual results may differ materially from those described above. You should read this information together with the financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for prior periods included in our most recent Annual Report on Form 10-K for the fiscal year ended January 1, 2017 and our most recent Quarterly Report on Form 10-Q for the fiscal quarter ended April 2, 2017.

Neither our independent registered public accounting firm nor any other independent registered public accounting firm has audited, reviewed or compiled, examined or performed any procedures with respect to the estimated results, nor have they expressed any opinion or any other form of assurance on the estimated results.

Adjusted EBITDA Description and Reconciliation

We present Adjusted EBITDA 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 income tax (benefit), depreciation and amortization and interest expense, net of interest income. Adjusted EBITDA is further adjusted for stock-based compensation expense, related party advisory fees, loss (gain) on sale of assets, other non-cash items, other non-recurring (income) and loss. We believe that Adjusted EBITDA is an important supplemental measure of operating performance because:

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. For example, this measure:

Management compensates for these limitations by relying primarily on our GAAP results and by using Adjusted EBITDA only as a supplement to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. 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.

The following table reconciles Adjusted EBITDA to net income for the periods presented:
