Myers Industries Reports 2013 First Quarter Results

Net sales rose 8.1% helped by last year’s acquisitions

First quarter EPS was lower year-over-year as anticipated

Continue to expect year-over-year EPS improvement for the remainder of 2013

Lawn and Garden Segment improves due to cost reductions

April 24, 2013, Akron, Ohio - Myers Industries, Inc. (NYSE: MYE) today announced results for the first quarter ended March 31, 2013.

Net sales in the first quarter of 2013 rose 8.1% to $215.0 million from $198.8 million in the first quarter of 2012 primarily due to last year’s acquisitions of Novel and Jamco. Sales increases in the Material Handling and Lawn & Garden Segments more than offset relatively flat sales quarter-over-quarter in the Distribution and Engineered Products Segments. The overall gross margin was 27.1% in the first quarter of 2013 compared to 29.2% in the first quarter of 2012. A change in customer and product mix quarter-over-quarter contributed to the decline in gross margin.

Net income in the first quarter of 2013 was $7.9 million, or $0.23 per diluted share, compared to net income of $10.0 million, or $0.29 per diluted share, in the first quarter of 2012. Income in the first quarter of 2013 included approximately $0.7 million of special pre-tax adjusted charges while income in the first quarter of 2012 included approximately $0.6 million of special pre-tax adjusted charges. Details regarding the special pre-tax adjusted charges for both quarters are provided on the Reconciliation of Non-GAAP Financial Measures included in this release. Earnings per diluted share as adjusted for the special charges were $0.24 in the first quarter of 2013 compared to $0.30 in the first quarter of 2012.

President and Chief Executive Officer John C. Orr said, “In our year-end 2012 earnings release we said the first quarter of 2013 would be challenging due to investments in information technology and other projects. We continue to anticipate that our full year 2013 results should improve over 2012. This improvement is driven by our efforts in cost reductions, new product innovation and increased sales. In addition, I am very pleased with our Lawn & Garden Segment’s adjusted profits which improved 125% this quarter and reflect our continued cost reduction efforts.”

Segment Results

The results below are as adjusted and exclude special pre-tax charges as detailed on the Reconciliation of Non-GAAP Financial Measures included in this release.

Net sales in the Material Handling Segment for the first quarter of 2013 were $80.0 million compared to $65.2 million for the first quarter of 2012. Sales resulting from the Novel and Jamco acquisitions produced most of the increase year-over-year. Material Handling’s adjusted income before taxes was $9.9 million for the first quarter of 2013 compared to $13.2 million for the first quarter of 2012. A change in both customer and product mix compared to last year was the primary driver behind the lower adjusted income before taxes year-over-year.

Net sales in the Lawn & Garden Segment for the first quarter of 2013 were $60.4 million compared to $59.2 million for the first quarter of 2012. Lawn & Garden’s adjusted income before taxes for the first quarter of 2013 was $2.7 million compared to $1.2 million for the first quarter of 2012. The higher sales combined with productivity improvements and material substitution cost savings led to the increase in income before taxes quarter-over-quarter.

Net sales in the Distribution Segment were $42.6 million for the first quarter of 2013 compared to $42.7 million for the first quarter of 2012. Distribution’s adjusted income before taxes was $2.9 million for the first quarter of 2013 compared to $3.9 million for the first quarter of 2012. A change in product mix of equipment versus supplies combined with planned information technology expenditures led to the decrease in adjusted income before taxes.

Net sales in the Engineered Products Segment were $37.0 million for the first quarter of 2013 compared to $37.2 million for the first quarter of 2012. Strong sales in the marine market were more than offset by more normal demand in the transplant auto market as compared to the first quarter of last year when the market was recovering from the tsunami in Japan. Engineered Products’ adjusted income before taxes was $5.1 million for the first quarter of 2013 compared to $4.7 million for the first quarter of 2012. The increase was driven by cost reductions.

Other Financial Items

For the three months ended March 31, 2013, cash flow used in operations was $6.5 million compared to $6.4 million in the first quarter of 2012. As is customary in the first quarter, the Company’s line of credit was used to fund the seasonal build of working capital.

During the first quarter of 2013, the Company repurchased 136,126 shares of stock under its current stock repurchase plan at an average price of $14.36 resulting in a cash outflow of $2.0 million.

Capital expenditures totaled $4.5 million for the three months ended March 31, 2013 and we continue to forecast total capital expenditures to be approximately $30 million to $35 million in 2013.

Second Quarter and Full-Year Outlook

“Starting in the second quarter, we expect improved year-over-year results,” said John Orr. “We continue to make progress in our strategic initiatives around cost reductions, material substitutions and new product development. We have seen improvements in our Lawn & Garden Segment’s profitability as a result of our cost reductions and material substitutions, and these are in addition to the previously announced internal project that we expect to generate additional annual savings of $5 million in 2014.”
