FOLSOM, Calif.

Waste Connections, Inc. today announced its results for the second quarter 2006. Revenue totaled $207.0 million, a 14.8% increase over revenue of $180.3 million in the year ago period. Operating income was $40.8 million versus $43.6 million in the second quarter of 2005. Net income was $19.2 million, or $0.41 per share on a diluted basis of 46.9 million shares. In the year ago period, the Company reported income from continuing operations of $21.8 million and diluted earnings per share from continuing operations of $0.45.

The Company noted three items in the second quarter 2006 results which combined to decrease diluted earnings per share by approximately $0.05:

* additional development costs for insurance claims from prior years of $3.8 million ($2.4 million net of taxes), or a reduction of approximately $0.05 per share;

* stock-based compensation costs of $1.0 million ($0.6 million net of taxes), or a reduction of approximately $0.01 per share; and

* reduced interest expense due to the redemption of convertible notes of $1.0 million ($0.6 million net of taxes), or an increase of approximately $0.01 per share.

"Pricing and volume growth remain above the upper end of our original expectations for the full year, and we expect this trend to continue during the third quarter. This strength has enabled us to offset higher than anticipated current year costs, primarily in fuel and related items. We expect this strong pricing environment to continue into next year and provide for margin expansion in 2007 when year-to-year costs again become more comparable," said Ronald J. Mittelstaedt, Chairman and Chief Executive Officer. "Fuel and related items increased as a percentage of revenue by approximately 265 basis points in the second quarter compared to the year ago period. This increase was due to the more than doubling of current fuel prices relative to prices we paid last year under a fixed-price fuel supply contract that expired at the end of 2005."

Mr. Mittelstaedt continued, "Acquisition activity increased significantly during the second quarter with the closing in early June of the previously announced purchase of El Dorado Disposal Service from Waste Management. El Dorado Disposal Service provides collection, recycling and transfer services in El Dorado County, California, under long-term franchise agreements. This acquisition together with previously announced awarded contracts already positions us for approximately 10% year-over-year reported revenue growth in 2007, excluding the impact of any additional acquisitions."

For the six months ended June 30, 2006, revenue was $397.1 million, a 15.2% increase over revenue of $344.7 million in the year ago period. Operating income was $80.0 million versus $82.3 million for the same period in 2005. Net income for the six months ended June 30, 2006, was $34.9 million, or $0.74 per share on a diluted basis of 47.2 million shares. In the year ago period, the Company reported income from continuing operations of $41.3 million and diluted earnings per share from continuing operations of $0.85.

The Company noted the following items in the current year six-month period which contributed to the year-over-year change in net income and diluted earnings per share:

* write-off of unamortized debt issuance costs associated with convertible notes redeemed during the second quarter of $4.2 million ($2.6 million net of taxes), or a decrease of approximately $0.06 per share;

* additional development costs for insurance claims from prior years of $3.8 million ($2.4 million net of taxes), or a decrease of approximately $0.05 per share;

* stock-based compensation costs of $1.6 million ($1.0 million net of taxes), or a decrease of approximately $0.02 per share; and

* reduced interest expense due to the redemption of convertible notes of $1.0 million ($0.6 million net of taxes), or an increase of approximately $0.01 per share.

Waste Connections will be hosting a conference call related to second quarter earnings and third quarter outlook on July 27th at 10:00 A.M. Eastern Time. The call will be broadcast live over the Internet at www.streetevents.com and through a link on the Company's web site at www.wasteconnections.com. A playback of the call will be available at both of these sites.

For non-GAAP measures, see accompanying Non-GAAP Reconciliation Schedule.

In the second quarter of 2005, Waste Connections classified as discontinued operations the results of certain operations in Utah and California that were exited during that quarter. Results for 2005 have been reclassified to present the results for these operations as discontinued operations.

In accordance with the Company's adoption of SFAS 123R at the beginning of the first quarter of 2006, excess tax benefits on the exercise of stock options, which totaled $5.5 million for the six months ended June 30, 2006, are now classified as a cash flow from financing activities, rather than as a cash flow from operating activities as classified in prior year periods. This requirement will reduce the amounts recorded as net cash provided by operating activities, and will increase the amount recorded as net cash provided by financing activities. In order to improve comparability to prior periods, the Company's definition of free cash flow, a non-GAAP financial measure, has been expanded to include the excess tax benefits on the exercise of stock options. Total cash flow will remain unchanged from what would have been reported under prior accounting rules.

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) efforts by labor unions could divert management attention and adversely affect operating results; (5) increases in insurance costs and the amount that Waste Connections self-insures for various risks could reduce its operating margins and reported earnings; (6) Waste Connections may lose contracts through competitive bidding, early termination or governmental action; (7) the geographic concentration of Waste Connections' business makes its results vulnerable to economic and seasonal factors affecting the regions in which it operates; (8) competition for acquisition candidates, consolidation within the waste industry and economic and market conditions may limit Waste Connections' ability to grow through acquisitions; (9) Waste Connections' growth and future financial performance depend significantly on its ability to integrate acquired businesses into its organization and operations; (10) Waste Connections' acquisitions may not be successful, resulting in changes in strategy, operating losses or a loss on sale of the business acquired; (11) 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; (12) 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; (13) 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; (14) Waste Connections' decentralized decision-making structure could allow local managers to make decisions that adversely affect Waste Connections' operating results; (15) Waste Connections' financial results are based upon estimates and assumptions that may differ from actual results; (16) Waste Connections may incur additional charges related to capitalized expenditures, which would decrease its earnings; (17) each business that Waste Connections acquires or has acquired may have liabilities that Waste Connections fails or is unable to discover, including environmental liabilities; and (18) 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 cash proceeds from disposal of assets and excess tax benefit on the exercise of stock options, plus or minus change in book overdraft, less capital expenditures 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.
