First Quarter of 2016 Compared to First Quarter of 2015

Net sales increased $31.1 million, or 12.5%, to $279.8 million, driven primarily by volume growth. Net sales of Dry Foods increased $25.2 million, or 12.4%, to $229.2 million while net sales of Wet Foods, Treats and Other Products increased $5.8 million, or 13.1%, to $50.6 million.

Gross profit increased $23.7 million, or 23.8%, to $123.2 million and gross margin was 44.0%, up 400 bps compared with 40.0% in the first quarter of 2015. The increase in gross margin was driven primarily by supply chain efficiencies including the ramp-up of our Heartland facility and lower input costs, as well as a benefit from net pricing.

Selling, general, and administrative expenses increased $12.4 million, or 26.1%, to $59.8 million. Adjusted SG&A, which excludes litigation expenses and costs incurred in preparing for our initial public offering, increased $12.5 million, or 27.3%. This increase was primarily due to our ongoing investments in advertising and marketing consistent with our brand building strategy, as well as investments made in our strategic initiatives.

Net income increased $7.3 million, or 24.3%, to $37.3 million, or $0.19 per diluted share in the first quarter of 2016, as compared to $30.0 million, or $0.15 per diluted share, in the first quarter of 2015. Adjusted Net Income, which excludes litigation expenses and costs incurred in preparing for our initial public offering, increased $7.2 million, or 23.2%, to $38.3 million in the first quarter of 2016, compared to $31.1 million in the first quarter of 2015. Adjusted Diluted Earnings Per Share in the first quarter of 2016 increased 23.0% to $0.19, compared to $0.16 in the first quarter of 2015.

Net cash provided by operating activities was $42.5 million in the first three months of 2016 compared with $56.4 million in the first three months of 2015. Net cash provided by operating activities for the first three months of 2016 was reduced by the $32 million cash payment related to our settlement agreement in the U.S. consumer class action lawsuits. Cash and cash equivalents were $265.1 million as of March 31, 2016 as compared to $224.3 million as of December 31, 2015.

Full Year 2016 Outlook

For the full year 2016, the Company expects to deliver net sales between $1,125 million and $1,140 million. The Company expects its gross margin to be between 43% and 44% for the year. Given this gross margin outlook, the Company will continue its planned investments in strategic initiatives and brand building. The Company expects its Adjusted Diluted Earnings Per Share to be between $0.73 and $0.74. The outlook for

full year 2016 Adjusted Earnings Per Share excludes costs related to litigation. The Company expects 2016 capital expenditures to be approximately $70 to $80 million.
