GWA Group Limited announced unaudited financial results for the six months ended December 2011. For the six months, revenue and trading earnings before interest and tax (EBIT) are in line with previous guidance to the market. Revenue was slightly down on the corresponding period last year and trading EBIT is in the $44 million to $46 million range. An underlying decline in revenue of approximately 11% for like for like businesses has been offset by revenue from Gliderol, which was acquired in January 2011. Revenue was adversely impacted by lower sales of environmental water heating products in the Dux business, the absence of government stimulus spending and the general downturn in the building sector and renovation activity. Net profit after tax will be impacted by restructuring costs and the results from discontinued operations during the half year. Each of these items will have a loss after tax in the range of $7 million to $8 million.
