Armstrong World Industries Reports First Quarter 2010 Results

LANCASTER, Pa., May 3 /PRNewswire-FirstCall/ — Armstrong World Industries, Inc. (NYSE: AWI) today reported first quarter 2010 net sales of $658.9 million, down 1 percent, from $668.3 million in the same period for 2009. Excluding a $19 million, or 3 percent, impact of foreign exchange rates, sales decreased 4 percent. Reported operating income was $13.4 million compared to $1.1 million in the first quarter of 2009. Adjusted operating income of $26.8 million increased significantly compared to $2.8 million on the same basis.

The Company uses adjusted income from operations in managing the business and believes the adjustments provide meaningful comparisons of operating performance between periods. Adjusted income excludes the translation impact of foreign exchange, restructuring charges and related costs, and certain other gains and losses. As detailed in the attached reconciliation to GAAP, these adjustments increased operating income by $13.4 million in the first quarter of 2010 and $1.7 million in the first quarter of 2009.

Reported net loss was $19.4 million, or $0.34 per diluted share. The Company recorded a $21.6 million deferred income tax charge to reflect the change in tax deductibility of retiree health costs related to Medicare Part D subsidies. This compared to a net loss of $11.2 million, or $0.20 per diluted share, in the first quarter of 2009. Adjusted net income was $13.7 million, or $0.24 per diluted share, compared to a loss of $0.4 million, or $0.01 per diluted share, on the same basis in 2009.

Significant reductions in operating costs more than offset the impact of lower sales to the 2010 first quarter adjusted operating income. Market trends broadly eased in the quarter. The rate of declines in most commercial and residential markets moderated, resulting in a 3 percent volume decline. Improved cost performance was driven by our manufacturing rationalization and SG&A reductions.

1st Quarter Segment Highlights

Resilient Flooring net sales were $232.6 million in the first quarter of 2010 compared to $241.2 million in the same period of 2009. Excluding an $8 million impact of foreign exchange, net sales declined about 7 percent. Lower sales volumes, particularly in the Americas markets, were the primary cause of the decline. Reported operating loss was $5.2 million compared to a loss of $12.9 million in the first quarter of 2009. The 2009 loss included $2 million of expense related to cost reduction efforts. European Resilient Flooring contributed losses of $7.1 million and $14.9 million, respectively to those totals. Operating loss was cut significantly as lower manufacturing and SG&A costs more than offset the margin impact of lower volume and reduced price realization.

Wood Flooring net sales of $124.3 million in the first quarter of 2010 grew 2 percent from $121.8 million in the prior year’s quarter on approximately flat volume and improved product mix. Reported operating loss of $1.6 million in the first quarter was lower than a loss of $7.8 million reported in 2009. The improvement was primarily due to reduced manufacturing expense and the margin benefit from increased sales, partially offset by raw material inflation and increased promotional spending.

Building Products net sales of $267.9 million in the first quarter of 2010 was flat with $266.9 million in the prior year’s quarter. Excluding a $10 million impact of foreign exchange, sales decreased by 3 percent. Price realization was down across geographies, volume declined in the Americas and European product mix was less profitable. Reported operating income increased to $42.7 million from $31.8 million in the first quarter of 2009. Reduced manufacturing expenses, higher earnings from WAVE and lower European input costs more than offset the margin impact of lower sales in local currency.

Cabinets 2010 first quarter net sales of $34.1 million were 11 percent below sales of $38.4 million in 2009 due to less volume. Reported operating loss for the first quarter of $3.9 million was better than the prior year’s $4.5 million loss. Operating loss decreased primarily due to reduced SG&A expenses, partially offset by the margin impact of lower sales.

Unallocated corporate expense of $18.6 million in the first quarter of 2010 compared to expense of $5.5 million in the first quarter of 2009. 2010 adjusted unallocated corporate expense was $4.3 million, with the adjustment of $11 million of severance expenses for our former Chairman and Chief Executive Officer and a $3 million asset impairment charge related to the termination of our flight operations.

Free cash flow was a use of $30 million in the first quarter of 2010 compared to a use of $45 million in 2009. The improvement was primarily due to a smaller increase in working capital.

Outlook

Global macroeconomic forecasts have modestly improved although most key markets are still expected to decline. North American commercial markets are expected to decline between 5 percent and 10 percent. North American residential markets are expected to be roughly flat, with an anticipated 14 percent improvement in U.S. housing starts, primarily in the second half, and a 2 percent increase in renovation. European markets are anticipated to decline approximately 5 percent.

Management expects 2010 sales to be between $2,700 million and $2,900 million. The adjusted operating income forecasted range has improved to between $150 million and $175 million, compared to $157 million in 2009. 2010 adjusted EPS is expected to be $1.35-$1.60 per diluted share, compared to $1.43 per diluted share in 2009. 2010 cash taxes are estimated to be less than $10 million. A 42 percent tax rate will be utilized for adjusted earnings to facilitate comparability from period to period. Free cash flow is anticipated to be between $50 million and $75 million.

Adjusted figures are reconciled to GAAP in tables at the end of this release.

These materials contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act. Such statements provide expectations or forecasts of future events.

We try to reduce both the likelihood that these risks will affect our businesses and their potential impact. However, no matter how accurate our foresight, how well we evaluate risks, and how effective we are at mitigating them, it is still possible that one of these problems or some other issue could have an adverse effect on our business, profitability, and the carrying value of assets.
