was $149.3 million, a 16.2% increase over revenue of $128.5 million in
the first quarter of 2003. Operating income for the first quarter of
2004 was $35.2 million, a 6.0% increase over operating income of $33.2
million in the first quarter of 2003. Net income for the first quarter
of 2004 was $16.2 million, a 12.4% increase over net income of $14.4
million before a gain resulting from the cumulative effect of adopting
SFAS No. 143 in the first quarter of 2003.
    Ronald J. Mittelstaedt, Chairman and Chief Executive Officer,
said, "We are very pleased with our first quarter performance.
Internal growth was especially strong, and free cash flow reached a
record level. The underlying performance of our business has been
trending better than expected other than rising medical costs. We are
seeing a pick up in business across all of our regions that suggest to
us that conditions overall are improving, and we believe that the
fundamentals are in place for the sequential margin improvement into
the second quarter that we had previously expected."
    Waste Connections will be hosting a conference call related to
first quarter earnings and the second outlook on April 22nd at 8:30
A.M. Eastern Time. The call will be broadcast live over the Internet

    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," or "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) difficulties in
making acquisitions, acquiring exclusive contracts and generating
internal growth may cause Waste Connections' growth to be slower than
expected; (2) Waste Connections' growth and future financial
performance depend significantly on its ability to integrate acquired
businesses into its organization and operations; (3) Waste
Connections' acquisitions may not be successful, resulting in changes
in strategy, operating losses or a loss on sale of the business
acquired; (4) Waste Connections competes for acquisition candidates
with other purchasers, some of which have greater financial resources
than it does, and these other purchasers may be able to offer more
favorable acquisition terms, thus limiting Waste Connections' ability
to grow through acquisition; (5) timing of acquisitions may cause
fluctuations in Waste Connections' quarterly results, which may cause
its stock price to decline; (6) rapid growth may strain Waste
Connections' management, operational, financial and other resources;
(7) Waste Connections may be unable to compete effectively with
governmental service providers and larger and better capitalized
companies, which may result in reduced revenues and lower profits; and
(8) Waste Connections may lose contracts through competitive bidding,
early termination or governmental action, which would cause its
revenues to decline. 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
after the date any such statement is made.

                        (Dollars in thousands)

Operating income before depreciation and amortization and free cash
flow, each a non-GAAP financial measure, are provided supplementally
because they are widely used by investors as valuation and financial
performance measures in the solid waste industry. These measures
should be used in conjunction with GAAP financial measures. Management
uses operating income before depreciation and amortization and free
cash flow as two of the principal measures to evaluate and monitor the
ongoing financial performance of our operations. Other companies may
calculate operating income before depreciation and amortization and
free cash flow differently.
