ATLANTA, July 29, 2020 /PRNewswire/ -- Marine Products Corporation (NYSE: MPX) announced its unaudited results for the quarter ended June 30, 2020. Marine Products is a leading manufacturer of fiberglass boats under three brand names: Chaparral, Robalo and Vortex. Chaparral's sterndrive models include SSi and SSX, along with the Chaparral Surf Series. Chaparral's outboard offerings include OSX Luxury Sportboats, the 257 SSX OB, SSi outboard models and SunCoast Sportdecks. Robalo builds an array of outboard sport fishing boats, which include center consoles, dual consoles and Cayman Bay Boat models. Chaparral also offers jet powered boats under the Vortex brand name.
For the quarter ended June 30, 2020, Marine Products generated net sales of $40,818,000, a 54.0 percent decrease compared to record net sales of $88,696,000 in the same period of the prior year. The decrease in net sales was due to a 57.9 percent reduction in the number of units sold during the quarter as compared to the prior year. Unit sales declined in every product category due to the temporary suspension of manufacturing operations for five weeks during the quarter. Average selling price per boat during the second quarter rose by 7.8 percent due to a favorable model mix.
Gross profit for the second quarter of 2020 was $7,831,000, a 61.7 percent decrease compared to gross profit of $20,424,000 in the same period of the prior year. Gross margin was 19.2 percent of net sales in the second quarter of 2020 compared to 23.0 percent in the second quarter of 2019. Gross margin as a percentage of net sales declined due to manufacturing cost inefficiencies resulting from the temporary operational suspension during the quarter, partially offset by a favorable model mix consisting of larger boats.
Operating profit for the second quarter of 2020 was $2,074,000, a decrease of 81.8 percent compared with operating profit of $11,379,000 in the second quarter of last year. Selling, general and administrative expenses were $5,757,000 in the second quarter of 2020 compared to $9,045,000 in the second quarter of 2019. The significant decrease in these expenses was due to reductions in costs that vary with sales and profitability, such as incentive compensation and warranty expense. In addition, selling, general and administrative expenses declined due to lower salaries arising from employee furloughs and reductions in other expenses due to the temporary operational suspension during the quarter. These decreases were partially offset by increases in research and development expenses as the Company continued development of new models for the 2021 model year. Selling, general and administrative expenses were 14.1 percent of net sales in the second quarter of 2020 compared to 10.2 percent of net sales during the second quarter of 2019.
Net income for the second quarter of 2020 was $1,707,000, a decrease of $7,666,000, or 81.8 percent, compared with record net income of $9,373,000 in the second quarter of 2019. Diluted earnings per share were $0.05 in the second quarter of 2020 compared to $0.27 in the second quarter of 2019. The effective tax rate for both the second quarter of 2020 and 2019 was 18.3 percent. Net sales for the six months ended June 30, 2020 were $99,937,000, a decrease of 41.8 percent compared to the first six months of 2019. Net income for the six-month period of 2020 was $5,915,000 or $0.17 diluted earnings per share, compared to net income of $16,842,000, or $0.49 diluted earnings per share in the prior year.
Richard A. Hubbell, Marine Products' President and Chief Executive Officer stated, "As we announced a few months ago, in late March we temporarily suspended manufacturing operations in response to concerns over the potential spread of COVID-19. Our Nashville, GA production facility did not resume operations until the second week in May, and as a result, our production and sales were dramatically impacted for almost half of the quarter. During this shutdown we continued with our research and development efforts, modified our marketing efforts to maintain our presence with dealers and customers, and reduced costs wherever possible. In addition, we expedited the shipment of as many boats as possible to our dealers to meet high retail demand.
"We resumed operations on May 6th at slightly higher production levels than during the first quarter. We are continuing to increase production early in the third quarter because of significantly higher dealer and consumer demand since mid-March. At the end of the second quarter, our dealer inventory was significantly lower than at the end of both the first quarter of 2020 and the second quarter of the prior year, and our order backlog was at its highest level in several years.
"It is clear that American consumers are choosing recreational boating as a safe, enjoyable outdoor activity suited for social distancing. We are very pleased to begin our 2021 model year in this favorable environment, and are working to increase production to meet this surge in demand with appealing new models. As always, we will monitor macroeconomic factors closely, and maintain a balance among high product demand, potential supply chain constraints, and our desire to produce quality products," concluded Hubbell.
