EXHIBIT 99.1 FOR IMMEDIATE RELEASE Contact: Friday, April 28, 2006 John F. Rebele Senior Vice President, Chief Financial Officer and Chief Administrative Officer Building Materials Corporation of America (973) 628-4038 BUILDING MATERIALS CORPORATION OF AMERICA ANNOUNCES --------------------------------------------------- FIRST QUARTER RESULTS --------------------- Building Materials Corporation of America ("BMCA" or "the Company") announced today first quarter of 2006 net income of $10.4 million compared to net income of $12.8 million in the first quarter of 2005. The decrease in first quarter 2006 net income was primarily attributable to lower income before interest expense and income taxes, partially offset by lower interest expense. Income before interest expense and income taxes in the first quarter of 2006 was $31.2 million compared to $36.8 million in the first quarter of 2005. Income before interest expense and income taxes in the first quarter of 2006 was positively affected by increased net sales of both residential and commercial roofing products primarily resulting from higher average selling prices, which was more than offset by higher raw material costs, including asphalt, higher energy costs and higher selling, general and administrative expenses mostly due to higher distribution costs, primarily resulting from a rise in fuel prices. - continued - Interest expense for the first quarter of 2006 decreased to $14.5 million from $16.1 million for the first quarter of 2005, primarily due to lower average borrowings. Net sales for the first quarter of 2006 reached $505.0 million, a 5.5% increase over first quarter of 2005 net sales of $478.8 million, with the increase due to higher net sales of both residential and commercial roofing products primarily resulting from higher average selling prices.
