FOLSOM, CA, October 19, 2010 - Waste Connections, Inc. (NYSE: WCN) today announced its results for the third quarter of 2010. Revenue totaled $345.8 million, a 9.4% increase over revenue of $316.0 million in the year ago period. Operating income was $75.7 million, or 21.9% of revenue, versus $64.8 million in the third quarter of 2009. Net income attributable to Waste Connections in the quarter was $41.0 million, or $0.53 per share on a diluted basis of 77.9 million shares. In the year ago period, the Company reported net income attributable to Waste Connections of $34.2 million, or $0.43 per share on a diluted basis of 79.8 million shares. The effective tax rate in the quarter was 39.2% compared to 36.0% in the year ago period.

Adjusted net income attributable to Waste Connections in the quarter was $41.4 million*, or $0.53 per share*, adjusting primarily for acquisition-related costs expensed due to the implementation of new accounting guidance for business combinations effective January 1, 2009. Adjusted net income attributable to Waste Connections in the prior year period was $35.0 million*, or $0.44 per share*, also adjusted primarily for acquisition-related costs.

Non-cash costs for equity-based compensation, amortization of acquisition-related intangibles, and amortization of debt discount related to convertible debt instruments in connection with the adoption of new accounting guidance on January 1, 2009, were $6.5 million ($4.0 million net of taxes, or approximately $0.05 per share) in the quarter compared to $7.2 million ($4.5 million net of taxes, or approximately $0.06 per share) in the year ago period.

“We once again are extremely pleased with our results in the quarter as we exceeded the upper end of our expectations. Increased special waste activity and MSW volumes at our landfills, combined with continuing strength in recycled commodity values and discipline in core pricing, were the primary drivers of an approximate 110 basis points expansion in adjusted operating income before depreciation and amortization* as a percentage of revenue and a more than 20% increase in earnings per share compared to the year-ago period,” said Ronald J. Mittelstaedt, Chairman and Chief Executive Officer. “Our strong operating performance and free cash flow generation continue to de-lever our balance sheet despite increasing outlays for share repurchases and acquisitions. The stock split and quarterly dividend initiation also announced today reinforce our commitment to broaden our investor base and maximize returns to shareholders, while maintaining continuing flexibility to fund our growth strategy.”

Mr. Mittelstaedt added, “Recent acquisition activity brings the total annualized revenue for signed or completed transactions year-to-date to approximately $40 million. In October, we acquired an E&P waste treatment and disposal company outside Lake Charles, Louisiana, that complements the integrated asset platform we acquired in Louisiana in July. We also signed an agreement to acquire Stutzman Refuse & Disposal Inc., a provider of solid waste collection and recycling services across 14 counties in central Kansas and contiguous to our existing operations; we expect this transaction to close in early November.”

For the nine months ended September 30, 2010, revenue was $983.8 million, an 11.6% increase over revenue of $881.5 million in the year ago period. Operating income was $204.6 million, versus $171.8 million for the same period in 2009. Net income attributable to Waste Connections for the nine months ended September 30, 2010, was $99.0 million, or $1.26 per share on a diluted basis of 78.3 million shares. In the year ago period, the Company reported net income attributable to Waste Connections of $86.6 million, or $1.08 per share on a diluted basis of 80.5 million shares. Adjusted net income attributable to Waste Connections for the nine months ended September 30, 2010, was $108.3 million*, or $1.38 per share*, compared to $88.6 million*, or $1.10 per share* in the year ago period.

For the nine months ended September 30, 2010, non-cash costs for equity-based compensation, amortization of acquisition-related intangibles, loss on the early redemption of the 2026 Notes (net of make-whole payment), and amortization of debt discount related to convertible debt instruments in connection with the adoption of new accounting guidance on January 1, 2009, were $22.8 million ($14.1 million net of taxes, or approximately $0.18 per share), compared to $19.8 million ($12.3 million net of taxes, or approximately $0.15 per share) in the year ago period.

Information Regarding Forward-Looking Statements

Certain statements contained in this release are forward-looking in nature, including statements related to expected share repurchases, dividend payments, expected revenues from closed acquisitions, the closing of signed acquisitions and future acquisition activity. These statements can be identified by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” or “anticipates,” or the negative thereof or comparable terminology, or by discussions of strategy. Our 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) our acquisitions may not be successful, resulting in changes in strategy, operating losses or a loss on sale of the business acquired; (2) a portion of our growth and future financial performance depends on our ability to integrate acquired businesses into our organization and operations; (3) downturns in the worldwide economy adversely affect operating results; (4) our results are vulnerable to economic conditions and seasonal factors affecting the regions in which we operate; (5) we may be subject in the normal course of business to judicial, administrative or other third party proceedings that could interrupt or limit our operations, require expensive remediation, result in adverse judgments, settlements or fines and create negative publicity; (6) we may be unable to compete effectively with larger and better capitalized companies and governmental service providers; (7) we may lose contracts through competitive bidding, early termination or governmental action; (8) price increases may not be adequate to offset the impact of increased costs or may cause us to lose volume; (9) increases in the price of fuel may adversely affect our business and reduce our operating margins; (10) increases in labor and disposal and related transportation costs could impact our financial results; (11) efforts by labor unions could divert management attention and adversely affect operating results; (12) we could face significant withdrawal liability if we withdraw from participation in one or more multiemployer pension plans in which we participate; (13) increases in insurance costs and the amount that we self-insure for various risks could reduce our operating margins and reported earnings; (14) competition for acquisition candidates, consolidation within the waste industry and economic and market conditions may limit our ability to grow through acquisitions; (15) our indebtedness could adversely affect our financial condition; we may incur substantially more debt in the future; (16) each business that we acquire or have acquired may have liabilities or risks that we fail or are unable to discover, including environmental liabilities; (17) liabilities for environmental damage may adversely affect our financial condition, business and earnings; (18) our accruals for our landfill site closure and post-closure costs may be

inadequate; (19) the financial soundness of our customers could affect our business and operating results; (20) we depend significantly on the services of the members of our senior, regional and district management team, and the departure of any of those persons could cause our operating results to suffer; (21) our decentralized decision-making structure could allow local managers to make decisions that adversely affect our operating results; (22) we may incur additional charges related to capitalized expenditures of landfill development projects, which would decrease our earnings; (23) because we depend on railroads for our intermodal operations, our operating results and financial condition are likely to be adversely affected by any reduction or deterioration in rail service; (24) our financial results are based upon estimates and assumptions that may differ from actual results; (25) the adoption of new accounting standards or interpretations could adversely affect our financial results; (26) our financial and operating performance may be affected by the inability to renew landfill operating permits, obtain new landfills and expand existing ones; (27) future changes in laws or renewed enforcement of laws regulating the flow of solid waste in interstate commerce could adversely affect our operating results; (28) extensive and evolving environmental and health and safety laws and regulations may restrict our operations and growth and increase our costs; (29) climate change regulations may adversely affect operating results; (30) extensive regulations that govern the design, operation and closure of landfills may restrict our landfill operations or increase our costs of operating landfills; (31) alternatives to landfill disposal may cause our revenues and operating results to decline; (32) fluctuations in prices for recycled commodities that we sell and rebates we offer to customers may cause our revenues and operating results to decline; and (33) unusually adverse weather conditions may interfere with our operations, harming our operating results.  These risks and uncertainties, as well as others, are discussed in greater detail in our filings with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q. There may be additional risks of which we are not presently aware or that we currently believe are immaterial which could have an adverse impact on our business. We make no commitment to revise or update any forward-looking statements in order to reflect events or circumstances that may change.

NON-GAAP RECONCILIATION SCHEDULE
(in thousands)

Reconciliation of Adjusted Operating Income before Depreciation and Amortization:

Adjusted operating income before depreciation and amortization, a non-GAAP financial measure, is provided supplementally because it is widely used by investors as a performance and valuation measure in the solid waste industry. Waste Connections defines adjusted operating income before depreciation and amortization as operating income, plus depreciation and amortization expense, plus closure and post-closure accretion expense, plus or minus any gain or loss on disposal of assets. The Company further adjusts this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP financial measures. Management uses adjusted operating income before depreciation and amortization as one of the principal measures to evaluate and monitor the ongoing financial performance of the Company’s operations. Other companies may calculate adjusted operating income before depreciation and amortization differently.

(in thousands, except per share amounts)

Reconciliation of Net Income to Adjusted Net Income and Adjusted Net Income per diluted share:

Adjusted net income and adjusted net income per diluted share, both non-GAAP financial measures, are provided supplementally because they are widely used by investors as a valuation measure in the solid waste industry. The Company provides adjusted net income to exclude the effects of items management believes impact the comparability of operating results between periods. Adjusted net income has limitations due to the fact that it may exclude items that have an impact on the Company’s financial condition and results of operations. Adjusted net income and adjusted net income per diluted share are not a substitute for, and should be used in conjunction with, GAAP financial measures. Management uses adjusted net income and adjusted net income per diluted share as one of the principal measures to evaluate and monitor ongoing financial performance of the Company’s operations. Other companies may calculate adjusted net income and adjusted net income per diluted share differently.

Reconciliation of Free Cash Flow:

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, plus or minus change in book overdraft, plus excess tax benefit associated with equity-based compensation, less capital expenditures for property and equipment and distributions to noncontrolling interests. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures. Management uses free cash flow as one of the principal measures to evaluate and monitor the ongoing financial performance of the Company’s operations. Other companies may calculate free cash flow differently.
