Marine Products Corporation Reports First Quarter 2019 Financial Results

ATLANTA, April 24, 2019 – Marine Products Corporation (NYSE: MPX) announced its unaudited results for the quarter ended March 31, 2019. Marine Products is a leading manufacturer of fiberglass boats under three brand names: Chaparral, Robalo and Vortex. Chaparral’s sterndrive models include Signature Cruisers, SSX and SSI Sportboats, Sunesta Sportdecks and H2O Sport and Ski & Fish Boats. The Chaparral Surf Series includes select models from the SSX, SSI, Sunesta and H2O lineups. Chaparral’s outboard offerings include OSX Sport Luxury, SunCoast Sportdecks and select H2O models. In addition, Chaparral offers jet powered boats with its Vortex Jet Boats lineup. Robalo builds outboard sport fishing boats, which include center console, dual console, walkaround cabin and Cayman bay boat models.

For the quarter ended March 31, 2019, Marine Products generated net sales of $83,053,000, a 7.1 percent increase compared to $77,536,000 in the same period of the prior year. The increase in net sales was due to a 14.8 percent increase in average selling prices and an increase in parts and accessories sales, partially offset by a 6.8 percent decrease in the number of units sold. In general, sales of smaller boats accounted for the decrease in unit sales during the quarter.

Gross profit for the first quarter of 2019 was $18,699,000, a 5.9 percent increase compared to gross profit of $17,651,000 in the same period of the prior year. The increase in gross profit was due to higher net sales. Gross margin as a percentage of net sales was 22.5 percent in the first quarter of 2019, compared with 22.8 percent in the first quarter of 2018. Gross margin as a percentage of net sales declined slightly due to higher labor costs as a percentage of net sales during the first quarter of 2019 as compared to the same period in 2018.

Operating profit for the first quarter of 2019 was $8,868,000, a decrease of 1.8 percent compared with operating profit of $9,033,000 in the first quarter of last year. Selling, general and administrative expenses were $9,831,000 in the first quarter of 2019, compared with $8,618,000 in the first quarter of 2018. These expenses increased due to expenses that increase with higher sales and profitability, such as incentive compensation, as well as higher research and development expenses which support new product development. Selling, general and administrative expenses as a percentage of net sales were 11.8 percent in the first quarter of 2019 compared with 11.1 percent of net sales during the first quarter of 2018.

Net income for the first quarter of 2019 was $7,469,000, a decrease of $140,000, or 1.8 percent, compared with net income of $7,609,000 in the first quarter of 2018. Diluted earnings per share were $0.22 in the first quarters of 2019 and 2018. The effective tax rate for the first quarter of 2019 was 16.3 percent, approximately the same as the effective tax rate of 16.1 percent for the first quarter of the prior year.

Richard A. Hubbell, Marine Products’ President and Chief Executive Officer stated, “During the first quarter, we sold fewer of our small boats to our dealer network, resulting in a 6.8 percent decrease in unit sales. Sales declines were concentrated in our smallest Robalo models and Chaparral H2O models. By contrast, we realized increased sales of larger Chaparral H2O models, larger Chaparral SSX and Robalo models, and generated our first sales of Chaparral’s 300 OSX Sport Luxury outboards. The model mix that resulted from these shifts allowed us to generate an increase in net sales and gross profit.

“We believe that the remainder of the 2019 retail selling season will be fairly strong, but we are closely monitoring retail demand among our various products. At the end of the first quarter, our dealer inventories were comparable to inventory levels at the same time in 2018. Unit order backlog was moderately lower at the end of the quarter, so we have reduced production slightly in order to maintain healthy dealer inventory levels in preparation for the 2020 model year. I am pleased to report that Marine Products Corporation continues to maintain industry-leading market share. For the 12 months ended December 31, 2018, Chaparral’s sterndrive products continued to hold the highest market share in their size category. Robalo continued to hold the second-highest market share in its category, and the combination of Robalo and Chaparral’s outboard boats held 6.8 percent of their market in 2018, the third highest in that category. We are proud of the successes of our new products during the 2019 model year, and the continued strong market share in these categories confirms the appeal of our new designs among our customer base. During the first quarter of 2019 we repurchased 263,805 shares of our common stock on the open market. In spite of this use of cash, we finished the quarter with $18.3 million in cash, an increase of $1.9 million compared to cash and marketable securities at the end of 2018,” concluded Hubbell.
