Waste Connections, Inc. today announced its results for the second quarter 2007. Revenue totaled $241.1 million, a 16.5% increase over revenue of $207.0 million in the year ago period. Operating income was $53.8 million, a 31.8% increase over operating income of $40.8 million in the second quarter of 2006. Net income in the quarter was $25.3 million, or $0.36 per share on a diluted basis of 70.6 million shares. In the year ago period, the Company reported net income of $19.2 million and diluted earnings per share of $0.27. Net income in the prior year period included additional development costs for insurance claims from prior years of $3.8 million ($2.4 million net of taxes, or approximately $0.03 per share).

"We continue to be extremely pleased with our results. Core pricing and commodity prices remain strong. Volume growth accelerated in the quarter due to typical seasonality, ramping of new contracts, and a notable increase in disposal volumes," said Ronald J. Mittelstaedt, Chairman and Chief Executive Officer. "We expect these trends to continue into the third quarter, putting us on track to exceed the upper end of our original outlook for the year."

For the six months ended June 30, 2007, revenue was $460.0 million, a 15.8% increase over revenue of $397.1 million in the year ago period. Operating income was $100.2 million, a 25.3% increase over operating income of $80.0 million for the same period in 2006. Net income for the six months ended June 30, 2007, was $47.6 million, or $0.67 per share on a diluted basis of 70.6 million shares. In the year ago period, the Company reported net income of $34.9 million, or $0.49 per share on a diluted basis of 70.9 million shares.

Certain statements contained in this press release are forward-looking in nature. These statements can be identified by the use of forward-looking terminology such as "believes," "expects," "may," "will," "should," "anticipates," or the negative thereof or comparable terminology, or by discussions of strategy. Waste Connections' business and operations are subject to a variety of risks and uncertainties and, consequently, actual results may differ materially from those projected by any forward-looking statements. Factors that could cause actual results to differ from those projected include, but are not limited to, the following: (1) Waste Connections may be unable to compete effectively with larger and better capitalized companies and governmental service providers; (2) increases in the price of fuel may adversely affect Waste Connections' business and reduce its operating margins; (3) increases in labor and disposal and related transportation costs could impact Waste Connections' financial results; (4) increases in insurance costs and the amount that Waste Connections self- insures for various risks could reduce its operating margins and reported earnings; (5) Waste Connections' financial results are based upon estimates and assumptions that may differ from actual results; (6) efforts by labor unions could divert management attention and adversely affect operating results; (7) Waste Connections may lose contracts through competitive bidding, early termination or governmental action; (8) Waste Connections' results are vulnerable to economic conditions and seasonal factors affecting the regions in which it operates; (9) Waste Connections may be subject in the normal course of business to judicial and administrative proceedings that could interrupt its operations, require expensive remediation and create negative publicity; (10) competition for acquisition candidates, consolidation within the waste industry and economic and market conditions may limit Waste Connections' ability to grow through acquisitions; (11) Waste Connections' growth and future financial performance depend significantly on its ability to integrate acquired businesses into its organization and operations; (12) Waste Connections' acquisitions may not be successful, resulting in changes in strategy, operating losses or a loss on sale of the business acquired; (13) because Waste Connections depends on railroads for its intermodal operations, its operating results and financial condition are likely to be adversely affected by any reduction or deterioration in rail service; (14) Waste Connections' intermodal business could be adversely affected by steamship lines diverting business to ports other than those Waste Connections services, or by heightened security measures or actual or threatened terrorist attacks; (15) Waste Connections depends significantly on the services of the members of its senior and district management team, and the departure of any of those persons could cause its operating results to suffer; (16) Waste Connections' decentralized decision-making structure could allow local managers to make decisions that adversely affect Waste Connections' operating results; (17) Waste Connections may incur additional charges related to capitalized expenditures, which would decrease its earnings; (18) the outcome of audits by the Internal Revenue Service may adversely affect Waste Connections; (19) each business that Waste Connections acquires or has acquired may have liabilities that Waste Connections fails or is unable to discover, including environmental liabilities; (20) liabilities for environmental damage may adversely affect Waste Connections' business and earnings; and (21) the adoption of new accounting standards or interpretations could adversely impact Waste Connections' financial results. These risks and uncertainties, as well as others, are discussed in greater detail in Waste Connections' filings with the Securities and Exchange Commission, including its most recent Annual Report on Form 10-K. There may be additional risks of which Waste Connections is not presently aware or that it currently believes are immaterial which could have an adverse impact on its business. Waste Connections makes no commitment to revise or update any forward-looking statements in order to reflect events or circumstances that may change.

  Free cash flow, a non-GAAP financial measure, is provided supplementally
  because it is widely used by investors as a valuation and liquidity
  measure in the solid waste industry.  Waste Connections defines free cash
  flow as net cash provided by operating activities, plus proceeds from
  disposal of assets and excess tax benefit associated with equity-based
  compensation, plus or minus change in book overdraft, less capital
  expenditures for property and equipment and distributions to minority
  interest holders.  This measure is not a substitute for, and should be
  used in conjunction with, GAAP financial measures. Management uses free
  cash flow as one of the principal measures to evaluate and monitor the
  ongoing financial performance of our operations.   Other companies may
  calculate free cash flow differently.
