Gundle/SLT Environmental, Inc. Announces Fourth Quarter and Year End Results

Gundle/SLT Environmental, Inc. (GSE), today reported a net income of $1.7 million for the quarter ended December 31, 2006, compared with net loss of $.4 million for the 2005 comparable period. Revenues for the fourth quarter of 2006 were $103.6 million, up from $73.4 million for the same quarter of 2005, a 41% increase. For the year ended December 31, 2006, the Company recorded net loss of $2.5 million compared to a net income of $.7 million in 2005. Revenues for fiscal 2006 were $373.3 million compared to $317.6 million in 2005, an 18% increase.

Samir T. Badawi, President and Chief Executive Officer said, "2006 was a good year and finished with a strong fourth quarter. While we have continued to face a volatile resin market, gross profit slightly increased over 2005. We overcame the decline in the South American mining market and the loss generated from the UK installation business from national solid waste customers by procuring higher sales in the U.S. and other international markets, and from higher margins in installation services in Germany. During the fourth quarter, we completed an add-on acquisition in the synthetic turf market, and acquired the rights to commercialize a pending patent for storm water detention systems that should introduce us to the storm water management business. These acquisitions, along with other measures for cost reduction, will help us diversify our customer base for 2007 and improve GSE's revenue and profitability in the future."

Income from operations in the fourth quarter of 2006 was $9.9 million, compared with $3.9 million in the fourth quarter of 2005. Gross profit in the fourth quarter of 2006 increased due to higher volumes and increased gross margins on a dollar per unit basis, as compared to the same period in 2005. Also contributing to this increase is lower selling, general and administrative expenses and $.4 million incurred in 2005 related to due diligence costs on previous acquisition opportunities no longer pursued. For fiscal 2006, income from operations was $19.8 million, compared to $21.0 million in 2005. The decrease was primarily due to higher selling, general and administrative expenses which included the settlement of a legal case, the recording of stock option expense for the 2006 grant and incurred severance costs.

Earnings before interest, taxes, depreciation and amortization, or EBITDA, as adjusted in accordance with the terms of the Company's credit agreement for its senior credit facility, was $15.7 million for the fourth quarter of 2006, up $5.8 million or 60% from the comparable period in 2005. For fiscal 2006, adjusted EBITDA was $43.3 million compared to $40.9 million in 2005.

EBITDA and Adjusted EBITDA

EBITDA and Adjusted EBITDA are presented because they are believed to be frequently used by parties interested in Gundle/SLT Environmental, Inc. (GSE). Management believes that EBITDA and Adjusted EBITDA provide useful information to lenders, note holders and investors because they facilitate the comparison of GSE's operating results to that of companies with different capital structures and with cost basis in assets that have been revalued and written- up in an allocation of a recent acquisition's purchase price.

The calculation of Adjusted EBITDA, presented above, is as defined in the credit agreement for GSE's senior credit facility. Adjusted EBITDA is used to measure compliance with covenants in the credit agreement, such as interest coverage and leverage ratio.

EBITDA and Adjusted EBITDA are not measures of financial performance under United States generally accepted accounting principles (US GAAP) and should not be considered as alternatives to net income, operating income or any other performance measures derived in accordance with US GAAP or as an alternative to cash flow from operating activities as a measure of liquidity.
