ADVANCED DRAINAGE SYSTEMS ANNOUNCES FISCAL YEAR 2016 UNAUDITED RESULTS

HILLIARD, Ohio – (June 7, 2016) – Advanced Drainage Systems, Inc. (NYSE: WMS) (“ADS” or the “Company”), a leading global manufacturer of water management products and solutions for commercial, residential, infrastructure and agricultural applications, today announced financial results on an unaudited basis for the fiscal year ended March 31, 2016.

Fiscal Year Ended March 31, 2016 Highlights

Joe Chlapaty, Chairman and Chief Executive Officer of ADS commented, “In fiscal year 2016, we experienced net sales growth of 9.3% compared to fiscal year 2015, driven primarily by healthy conversion and favorable weather conditions in the majority of our end markets, as well as contributions from the Ideal Pipe acquisition. Our sales were particularly strong in the second half of the fiscal year, as we generated net sales growth of 11.8% in the third quarter and 17.9% in the fourth quarter, more than offsetting a slower-than-expected start to the year. Our strong second half performance reflected significant growth in our Allied Products and healthy Pipe sales, as we continued to gain market share by capitalizing on conversion opportunities. Our performance in the domestic construction markets was also strong, as we grew 10.6% for the year compared to the estimated market growth of only 5%.”

Chlapaty continued, “We are pleased with our full year 2016 results and continue to see significant opportunity for further growth and operating leverage as we look ahead to 2017 and beyond. We currently expect the momentum that we experienced in the second half of the year to continue into fiscal year 2017, complemented by favorable raw material and energy costs. We remain confident in our ability to generate above-market growth across all of our end markets as we execute our growth strategy of conversion from alternative materials with our broad portfolio of Pipe and Allied Products.”

Fiscal Year 2016 Results

Gross profit increased $74.5 million, or 36.2 %, to $280.7 million for fiscal year 2016, compared to $206.1 million for the prior fiscal year. As a percentage of net sales, gross profit was 21.8%, compared to 17.5%, for the prior fiscal year. The increase in gross profit was largely attributed to increased revenues combined with lower raw material and transportation costs.

The Company reported Adjusted EBITDA (Non-GAAP) of $185.9 million in the full fiscal year 2016 compared to Adjusted EBITDA of $143.8 million in the prior fiscal year, an increase of 29.3%. As a percentage of net sales, Adjusted EBITDA was 14.4% for the fiscal year 2016 compared to 12.2% in the prior fiscal year. The increase in Adjusted EBITDA was largely attributed to the factors mentioned above offset by settlement losses on hedge positions primarily related to polypropylene resins.

Adjusted Earnings per fully converted share (Non-GAAP) for the fiscal year 2016 was $0.42 per share based on weighted average fully converted shares of 73.5 million, improved from an adjusted earnings per fully converted share of $0.29 per share for the prior year.

A reconciliation of GAAP to Non-GAAP financial measures for Adjusted EBITDA, Free Cash Flow and Adjusted Earnings per fully converted share has been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading “Non-GAAP Financial Measures.”

For fiscal year 2016, the Company recorded net cash provided by operating activities of $134.8 million compared to $74.4 million for the same period last year. Long Term Debt was $350.2 million as of March 31, 2016, a reduction of $49.7 million from March 31, 2015.

Fiscal Year 2017 Outlook

Based on current visibility, backlog of existing orders and business trends, the Company provided its financial targets for fiscal year 2017. Net sales for fiscal year 2017 are forecasted to be in the range of $1.330 billion to $1.380 billion, while the outlook for Adjusted EBITDA (Non-GAAP) is expected to be in the range of $205 million to $230 million. Capital expenditures are expected to be approximately $50-55 million.

Scott Cottrill, Executive Vice President and Chief Financial Officer of ADS, commented, “Our guidance for fiscal year 2017 reflects anticipated overall domestic end market growth of 4% to 7% in our construction related end markets and a decline of 5% to 12% in the agriculture market. In addition, international net sales are expected to be relatively soft, driven by weakness in the Mexican economy and flat sales in Canada due to a weaker agriculture market that we believe will offset growth in our construction markets. Adjusted EBITDA is forecasted to improve by 10% to 24% driven by higher sales volumes, as well as a favorable cost environment due to lower raw material costs, partially offset by anticipated lower selling prices and higher SG&A expenses.”

Non-GAAP Financial Measures

This press release contains financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“ GAAP”). ADS management uses non-GAAP measures in its analysis of the Company’s performance. Investors are encouraged to review the reconciliation of non-GAAP financial measures to the comparable GAAP results available in the accompanying tables.

Reconciliation of Non-GAAP Financial Measures

This press release includes references to Adjusted EBITDA, Free cash flow and Adjusted earnings per fully converted share, all non-GAAP financial measures. These non-GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP. These measures are not intended to be substitutes for those reported in accordance with GAAP. Adjusted EBITDA, Free Cash Flow, and Adjusted Earnings per Fully Converted Share may be different from non-GAAP financial measures used by other companies, even when similar terms are used to identify such measures.

Adjusted EBITDA is a non-GAAP financial measure that comprises net income before interest, income taxes, depreciation and amortization, stock-based compensation, non-cash charges and certain other expenses. The Company’s definition of Adjusted EBITDA may differ from similar measures used by other companies, even when similar terms are used to identify such measures. Adjusted EBITDA is a key metric used by management and the Company’s board of directors to assess financial performance and evaluate the effectiveness of the Company’s business strategies. Accordingly, management believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as the Company’s management and board of directors. In order to provide investors with a meaningful reconciliation, the Company has provided below a reconciliation of net income with Adjusted EBITDA as originally reported, and the impact of the restatement adjustments identified to date on Adjusted EBITDA.

Free Cash Flow is a non-GAAP financial measure that comprises cash flow from operations less capital expenditures and expenditures for capitalized software. Free Cash Flow is a measure used by management and the Company’s board of directors to assess the Company’s ability to generate cash. Accordingly, management believes that Free Cash Flow provides useful information to investors and others in understanding and evaluating our ability to generate cash flow from operations after capital expenditures. In order to provide investors with a meaningful reconciliation, the Company has provided below a reconciliation of cash flow from operating activities to Free Cash Flow.

Adjusted Earnings per Fully Converted Share is a non-GAAP measure that is calculated by adjusting our net income per share – Basic and Weighted average common shares outstanding – Basic, the most comparable GAAP measures. To effect this adjustment, we have (1) removed the accretion of Redeemable noncontrolling interest, (2) removed the adjustment for the change in fair value of Redeemable convertible preferred stock classified as mezzanine equity from the numerator of the Net income per share - Basic computation, (3) added back the dividends to Redeemable convertible preferred stockholders and dividends paid to unvested restricted stockholders, (4) made corresponding adjustments to the amount allocated to participating securities under the two-class earnings per share computation method, and (5) added back ESOP deferred compensation attributable to the shares of Redeemable convertible preferred stock allocated to employee ESOP accounts during the applicable period, which is a non-cash charge to our earnings. We have also made adjustments to the Weighted average common shares outstanding – Basic to assume (1) share conversion of the Redeemable convertible preferred stock outstanding shares to common stock and (2) add shares of outstanding unvested restricted stock. Adjusted earnings per fully converted share (non-GAAP) is included because it is a key metric used by management and our board of directors to assess our financial performance.

The following tables present a reconciliation of Adjusted EBITDA to Net Income, Free Cash Flow to Cash Flow from Operating Activities, and Adjusted Earnings per Fully Converted Share to Earnings per Share, the most comparable GAAP measures, for each of the periods indicated:
