DREW INDUSTRIES REPORTS SECOND QUARTER 2013 RESULTS

Elkhart, Indiana – August 6, 2013 – Drew Industries Incorporated (NYSE: DW), a leading supplier of components for recreational vehicles (RVs) and manufactured homes, today reported net income of $15.9 million, or $0.67 per diluted share, for the second quarter ended June 30, 2013, net of a previously announced after-tax charge of $0.4 million related to executive succession. Excluding this charge, net income in the second quarter of 2013 would have been $16.3 million, or $0.69 per diluted share, an increase of 39 percent compared to net income of $11.7 million, or $0.52 per diluted share, in the second quarter of 2012.

“Our operating profit margins improved sequentially in the second quarter of 2013 primarily due to efficiency improvements implemented by management, as well as the benefits of spreading fixed costs over a seasonally larger sales base and seasonally lower payroll taxes,” said Jason Lippert, Drew’s Chief Executive Officer. “This sequential margin gain was greater than originally expected, as many of the improvements implemented by management resulted in efficiency gains sooner than anticipated. We were confident that the steps we had taken to meet anticipated customer demand and improve profitability were correct, and it was reassuring to see the results of these efforts in the 2013 second quarter.”

Net sales in the second quarter of 2013 increased to a record $287 million, 14 percent higher than the same period last year. The increase in Drew’s second quarter net sales was a result of a 16 percent sales increase by Drew’s RV Segment, which accounted for 88 percent of consolidated net sales this quarter. RV Segment sales growth was largely due to a 12 percent increase in industry-wide wholesale shipments of travel trailer and fifth-wheel RVs, Drew’s primary RV market. Sales of recently introduced components for towable and motorhome RVs also contributed to the revenue increase, as did sales to adjacent industries and the aftermarket.

The Company’s content per travel trailer and fifth-wheel RV and motorhome RV for the twelve months ended June 2013 increased 5 percent and 23 percent, respectively, from the year-earlier period as a result of recent product introductions, product improvements and market share gains. The Company’s content per manufactured home for the twelve months ended June 2013 declined 3 percent from the year-earlier period primarily due to customer mix. The change in content per RV and manufactured home is a measure of the change in Drew’s overall market share across its existing product lines.

Retail demand for towable RVs increased 10 percent in the first five months of 2013, following an 8 percent increase in retail demand for the full year 2012. June 2013 retail data is not yet available. Most industry analysts report that dealer inventories of towable RVs are in line with anticipated retail demand. Future RV industry-wide production levels will depend on the strength of future retail sales.

“Our labor efficiencies continued to improve, with labor costs as a percent of sales declining in the second quarter of 2013,” continued Jason Lippert. “This improvement followed a sequential reduction of labor as a percent of sales of more than 1 percent in the first quarter of 2013. These reductions during the first two quarters of 2013 were primarily due to improved production processes, as well as expected declines in the costs of implementing facility consolidations and realignments. Nonetheless, we are continuing to implement additional efficiency improvements as we identify them. However, the benefits of such improvements on our operating margins in the latter half of 2013 will likely be offset by the spreading of fixed costs over a seasonally smaller sales base.”

In July 2013, Drew’s consolidated net sales reached approximately $83 million – 13 percent higher than in July 2012 – as a result of continued solid growth in the Company’s RV Segment. Drew estimates that industry-wide wholesale shipments of travel trailer and fifth-wheel RVs increased 7 percent in July 2013 compared to July 2012. Drew also estimates that July 2013 industry-wide production of manufactured homes increased 5 to 10 percent compared to July 2012.

“Since the end of 2011, we have achieved significant growth, with our net sales for the twelve months ended June 30, 2013 increasing over $285 million, or 42 percent,” said Scott Mereness, Drew’s President. “In response to this sales growth, and in anticipation of future growth, we added significant resources, investing in personnel and facilities to expand and improve production capacity, as well as to improve customer service. Many of the benefits and efficiencies of these initiatives were realized in the 2013 second quarter. Having just completed the peak seasonal period, we are now evaluating our human resource and facility requirements for the balance of 2013 and beyond.”

Jason Lippert added, “We will continue to invest in resources to strategically grow the business, especially in research and development, to provide creative and unique products. Staying ahead of the market through innovation has been important to our success, and will be even more important to maintaining our position as a leading supplier to the industries we serve. In addition, we will invest in areas where we believe additional savings can be realized, such as purchasing, automation and human resources. While some of these initiatives and related fixed costs may have a negative impact on operating margins in the short term, we believe they will benefit the long-term growth of the Company.”

“As previously announced, Fred Zinn retired as President and CEO in May 2013,” said Leigh Abrams, Chairman of Drew’s Board of Directors. “Jason Lippert became Drew’s CEO, and Scott Mereness became Drew’s President. Jason and Scott have been vital to our sales growth and operational success for many years and are highly respected throughout the industries we serve. As expected, this executive succession transition was very smooth, and we are confident that Jason, Scott and their team are ready to lead Drew for many years to come.”

As a result of the Company’s executive succession and corporate relocation from New York to Indiana, a pre-tax charge of $0.7 million was recorded in the second quarter of 2013 related to contractual obligations for severance and the acceleration of equity awards held by certain employees whose employment terminated. No other related charges are expected. Once the transition and corporate office relocation are completed during the latter half of 2013, the Company expects to save approximately $2 million annually.

“Our operating cash flow in the second quarter of 2013 remained strong,” said Joe Giordano, Drew’s Chief Financial Officer and Treasurer. “At the end of the quarter, we had no debt, $32 million of cash and substantial available credit lines, and we expect continued solid cash flow. We are well positioned to take advantage of attractive investment opportunities that can further improve our results.”

In the second quarter of 2013, the Company refined the calculation of RV content per unit. This refinement had no impact on total RV Segment net sales or trends of content per unit. Prior periods have been reclassified to conform to this presentation.

The trend in the Company’s average product content per RV produced is an indicator of the Company’s overall market share of components for new RVs. The Company’s average product content per type of RV, calculated based upon the Company’s net sales of components to RV OEMs for the different types of RVs produced for the respective twelve month period, divided by the industry-wide wholesale shipments of the different types of RVs for the same period, was:
