WASTE SERVICES REPORTS SECOND QUARTER RESULTS

BURLINGTON, Ontario, July 27, 2005/PRNewswire-FirstCall/ – Waste Services, Inc. (Nasdaq: WSII) today reported financial results for the three months ended June 30, 2005. Revenue for the quarter was $95.4 million, an increase of $22.8 million, or 31% over the same period last year. The increase in revenue was driven by business acquisitions of $8.8 million, pricing increases of $2.4 million, additional fuel surcharges to offset increased fuel costs of $1.5 million, increased volume at our landfill sites of $3.5 million, internal growth of $2.6 million, and other increases of $0.6 million. The favorable effects of foreign exchange movements also contributed $3.4 million to the increase. EBITDA* was $11.4 million for the three months ended June 30, 2005, compared to $8.7 million for the same period last year. Adjusted EBITDA* (as defined in our credit agreement) was $13.3 million for the three months ended June 30, 2005. Net loss attributable to common shareholders for the three months ended June 30, 2005 was $14.5 million, or $0.15 per share, versus a loss of $18.6 million, or $0.21 per share, for the comparable period last year.

For the six months ended June 30, 2005, revenue was $184.4 million, an increase of $61.5 million, or 50% over the comparable period last year. Net loss attributable to common shareholders was $28.8 million for the six months ended June 30, 2005, or $0.29 per share, compared to a net loss attributable to common shareholders of $29.3 million, or $0.37 per share for the comparable period last year.

The Chief Executive Officer, David Sutherland-Yoest, stated, “We continue to make progress in increasing disposal volumes at our three municipal solid waste landfills in the United States and were pleased with the opening of our two transfer stations in Florida during the second quarter. We expect the third quarter to show a substantial increase in adjusted EBITDA* versus the second quarter.”

The following table reconciles the differences between EBITDA and Adjusted EBITDA, as defined in our credit agreement, for the three months ended June 30, 2005 (in thousands of US dollars) (unaudited):


EBITDA⁽¹⁾	$	11,385
Adjustments to EBITDA (as defined per credit agreement):
Non-cash charges ⁽²⁾		595
Other excludable expenses ⁽³⁾		1,336

Adjusted EBITDA ⁽¹⁾	$	13,316


⁽¹⁾		EBITDA and EBITDA as defined in our credit agreement (“Adjusted EBITDA”) are non-GAAP measures used by management to measure performance. We also believe that EBITDA and Adjusted EBITDA may be used by certain investors to analyze and compare our operating performance between accounting periods and against the operating results of other companies that have different financing and capital structures or tax rates and to measure our ability to service our debt. In addition, management uses EBITDA, among other things, as an internal performance measure. Our lenders also use Adjusted EBITDA to measure our ability to service and/or incur additional indebtedness under our credit facilities. However, EBITDA and Adjusted EBITDA should not be considered in isolation or as a substitute for net income, cash flows or other financial statement data prepared in accordance with US GAAP or as a measure of our performance, profitability or liquidity. EBITDA and Adjusted EBITDA are not calculated under US GAAP and therefore are not necessarily comparable to similarly titled measures of other companies.

⁽²⁾		Non-cash charges include stock-based compensation expense, foreign exchange gains and losses and other.

⁽³⁾		Other excludable expenses include professional fees for litigation and the re-audit of Florida Recycling, as well as severance and other costs.
