“We are pleased to announce another successful year highlighted by record sales and earnings. Our success is directly attributable to the tireless efforts of our contributors who continue to execute our proven “New to the Aftermarket” product development strategy while ensuring high levels of service to our customers and end users. I would like to thank all our contributors who continue to drive Dorman to new levels of performance. Our core mission continues to be identifying failure prone passenger car, light truck, and heavy duty truck parts that are only available from dealerships and make a high quality alternative available to our customers and end users. To that end, we continue to invest in our new product capabilities allowing us to deliver growth well in excess of industry growth levels. During 2016, we introduced 4,220 new parts, including 1,255 “Formerly Dealer Only” parts. Sales from New Product launched in the last twenty four months as a percentage of total sales was 17% and we remain confident that we can continue to deliver above average industry growth over the long term by remaining laser-focused on this “New to the Aftermarket” mission. As a result, our previously issued guidance for 2017 remains unchanged as we continue to expect mid to high single digit organic revenue and net income growth,” said Matt Barton, president and chief executive officer.
