      FOLSOM, Calif., April 23 /PRNewswire-FirstCall/ -- Waste Connections, Inc.
(NYSE: WCN) today announced its results for the first quarter 2007. Revenue
totaled $219.0 million, a 15.1% increase over revenue of $190.2 million in the
year ago period. Operating income was $46.4 million, an 18.6% increase over
operating income of $39.2 million in the first quarter of 2006. As a percentage
of revenue, operating income was 21.2%, a 60 basis point increase from 20.6% in
the year ago period despite an approximate 45 basis point increase in
equity-based compensation costs as a percentage of revenue. Equity-based
compensation costs, on a pre-tax basis, were $1.7 million and $0.6 million for
the first quarter of 2007 and 2006, respectively.

      Net income in the quarter was $22.4 million, or $0.32 per share on a
diluted basis of 70.6 million shares. In the year ago period, the Company
reported net income of $15.7 million and diluted earnings per share of $0.22.
Net income in the prior year period included a $4.2 million charge ($2.6 million
net of taxes, or approximately $0.04 per share) for the write-off of unamortized
debt issuance costs associated with convertible notes that subsequently were
redeemed. Shares and per share numbers reflect a three-for- two stock split
effective March 13, 2007.

      "We are extremely pleased with our results in the quarter and the
implications moving forward. Continued strong pricing growth, improved commodity
prices and a reduction in net days sales outstanding enabled us to exceed our
expectations for the quarter," said Ronald J. Mittelstaedt, Chairman and Chief
Executive Officer. "We expect volume growth to increase in the second quarter
given improving monthly trends experienced during the first quarter and the full
impact of two long-term contracts that commenced earlier in the year."

      Waste Connections will be hosting a conference call related to first
quarter earnings and second quarter outlook on April 24th at 8:30 A.M. Eastern
Time. The call will be broadcast live over the Internet at

      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.
