Myers Industries Reports 2017 First Quarter Results

Strong cash flow growth driven by working capital and capital spending discipline

May 8, 2017, Akron, Ohio - Myers Industries, Inc. (NYSE: MYE) today announced results for the first quarter ended March 31, 2017.

First Quarter 2017 Business Highlights

The Company reported net sales of $141.7 million, compared to $151.2 million in the first quarter of 2016. Gross profit margin decreased 230 basis points to 29.6 percent as compared to the prior year quarter, primarily due to lower sales volume and higher restructuring and manufacturing costs in the Material Handling Segment. Selling, general and administrative expenses declined by $3.9 million to $34.6 million, in the first quarter of 2017, with the improvement in expenses primarily attributable to lower compensation costs.

President and Chief Executive Officer Dave Banyard commented, “First quarter earnings were in line with our expectations, despite softer than expected demand in the auto aftermarket end market. Net sales were down mid-single digits due to the decline in auto aftermarket as well as the expected continued weakness in agricultural end markets. Despite the lower sales volumes, we are executing well on our strategic initiatives. We have made solid progress with our niche market growth teams, and our strategic realignment to improve operating flexibility is well underway. Our continued focus on working capital and disciplined capital spending helped us generate strong free cash flow of $12.6 million during the quarter.”

Segment Results

Net sales in the Material Handling Segment declined 5.4% (or 6.6% excluding currency fluctuation) as compared to the first quarter of 2016. The reduction in net sales was primarily due to decreased volume in the Company’s agricultural end market. GAAP operating income was $12.1 million compared to $7.4 million in the first quarter of 2016. GAAP operating income in the first quarter of 2016 included non-cash impairment charges of $8.5 million in Brazil. Adjusted operating income was $12.8 million compared to $16.0 million in the first quarter of 2016. The decline in adjusted operating income was primarily the result of lower sales volumes and some impact from higher commodity prices that the Company expects to recover with price increases moving forward.

Net sales in the Distribution Segment declined 8.6% as compared to the first quarter of 2016. The decrease in net sales was across all product lines, particularly in our northern sales regions as a milder winter had an adverse effect on demand. We also continued to see lower capital spending on equipment across all regions. Operating income was $1.5 million compared to $2.5 million in the first quarter of 2016. The decrease in operating income was primarily the result of lower sales volumes.

Other Financial Items

In March 2017, in order to enable greater financial flexibility, the Company entered into a Fifth Amended and Restated Loan Agreement (the “Loan Agreement”). The Loan Agreement replaced the pre-existing $300 million senior revolving credit facility with a $200 million facility and extended the term from December 2018 to March 2022.

2017 Outlook

The Company continues to anticipate that total revenue will be flat on a constant currency basis in fiscal year 2017 as compared to the prior year. Capital expenditures are expected to be in the range of $10 to $12 million, net interest expense in the range of $8 to $9 million, depreciation and amortization in the range of $32 to $34 million, and an effective tax rate of approximately 36%.
