First Quarter of 2017 Compared to First Quarter of 2016

Net sales increased $22.1 million, or 7.9%, to $302.0 million, driven primarily by volume growth. Net sales of Dry Foods increased $14.7 million, or 6.4%, to $245.2 million while net sales of Wet Foods, Treats and Other Products increased $7.5 million, or 15.1% to $56.8 million.

Gross profit increased $15.4 million, or 12.5%, to $138.7 million and gross margin was 45.9%, up 190 bps compared with 44.0% in the first quarter of 2016. The increase in gross margin was driven primarily by supply chain efficiencies including lower input costs, as well as a benefit from net pricing.

Selling, general, and administrative expenses increased $6.6 million, or 11.0%, to $66.3 million. Adjusted SG&A, which excludes litigation expenses, increased $6.3 million, or 10.9%. This increase was primarily due to our ongoing investments in advertising and marketing consistent with our brand building strategy.

Net income increased $6.8 million, or 18.1%, to $44.1 million, or $0.22 per diluted share in the first quarter of 2017, as compared to $37.3 million, or $0.19 per diluted share, in the first quarter of 2016. Adjusted Net Income, which excludes litigation expenses, increased $6.9 million, or 18.0%, to $45.2 million in the first quarter of 2017, compared to $38.3 million in the first quarter of 2016. Adjusted Diluted Earnings Per Share in the first quarter of 2017 increased 17.3% to $0.23, compared to $0.19 in the first quarter of 2016.

Net cash provided by operating activities was $53.4 million in the first three months of 2017 compared with $42.5 million in the first three months of 2016. Cash and cash equivalents were $338.2 million as of March 31, 2017 as compared to $292.7 million as of December 31, 2016.

Full Year 2017 Outlook

For the full year 2017, the Company expects to deliver net sales between $1,240 million and $1,270 million. The Company expects its Adjusted Diluted Earnings Per Share to be between $0.91 and $0.94. The outlook for full year 2017 Adjusted Earnings Per Share excludes costs related to litigation. The Company expects 2017 capital expenditures to be approximately $150 million to $170 million.

Important Information Regarding Non-GAAP Financial Measures

The Company presents non-GAAP financial measures, including Adjusted Net Income, Adjusted EBITDA, Adjusted Diluted EPS, Adjusted SG&A, Adjusted Income Taxes, Adjusted Operating Income and Adjusted Gross Profit, in this press release as management uses these measures in assessing our operating performance, and we believe they are helpful to investors, securities analysts and other interested parties, in evaluating the performance of companies in our industry. We also believe that these non-GAAP financial measures are useful to management and investors, securities analysts and other interested parties as measures of our comparative operating performance from period to period. These non-GAAP financial measures are not measurements of financial performance under GAAP. They should not be considered as alternatives to cash flow from operating activities, as measures of liquidity, or as alternatives to net income as a measure of our operating performance or any other measures of performance derived in accordance with GAAP. The methods used by the Company to calculate its non-GAAP financial measures may differ significantly from methods used by other companies to compute similar measures. As a result, any non-GAAP financial measures presented herein may not be comparable to similar measures provided by other companies. Please see the schedules to this press release for additional information and reconciliations of such non-GAAP financial measures to the nearest GAAP measure. With respect to our expectations under “Full Year 2017 Outlook” above, for Adjusted Diluted EPS a reconciliation to the closest corresponding GAAP financial measure is not available without unreasonable efforts on a forward-looking basis due to the high variability, complexity and low visibility with respect to litigation expenses excluded from this non-GAAP financial measure. We expect the variability of these charges to have a potentially unpredictable, and potentially significant, impact on our future GAAP financial results.
