HOUSTON — April 24, 2014— Waste Management, Inc. (NYSE: WM) today announced financial results for its quarter ended March 31, 2014. Revenues for the first quarter of 2014 were $3.40 billion compared with $3.34 billion for the same 2013 period. Net income ^(a) for the quarter was $228 million, or $0.49 per diluted share, compared with $168 million, or $0.36 per diluted share, for the first quarter of 2013. In the first quarter of 2013, adjusted net income was $186 million, or $0.40 per diluted share. ^(b)

David P. Steiner, President and Chief Executive Officer of Waste Management, commented, “We saw continued and strong momentum in both yield and cost controls in the first quarter of 2014 that helped drive a more than 35% improvement in reported net income, and more than 22% growth in earnings per share when looking at first quarter 2013 adjusted results. We also saw an increase of 170 basis points in our reported income from operations margin, or 140 basis points when compared to our first quarter 2013 adjusted results. Our yield was 2.6%, the highest level since 2011 and the fourth consecutive quarter over 2.0%. We also achieved SG&A cost savings of $15 million compared to the first quarter of 2013. During the first quarter, our net cash provided by operations improved to $584 million, our capital expenditures were constant at $266 million, and we had $166 million of divestiture proceeds, all of which resulted in free cash flow of $484 million, our highest amount since 2008.” ^(b)

KEY HIGHLIGHTS FOR THE FIRST QUARTER 2014

•    Revenue increased by 1.8%, or $60 million; excluding a negative $17 million in foreign currency translation, revenue would have increased 2.3%.

•    Internal revenue growth from yield for collection and disposal operations was 2.6%.

•    Core price, which consists of price increases and fees, other than the Company’s fuel surcharge, net of rollbacks, was 4.2%, up from 3.2% in the first quarter of 2013.

•    Internal revenue growth from volume was negative 1.8%, a 40 basis point sequential improvement from the fourth quarter of 2013.

•    Average recycling commodity prices were approximately 1.8% lower in the first quarter of 2014 compared with the prior year period. In total, recycling operations negatively affected earnings by less than $0.01 per diluted share when compared to the prior year period.

•    Operating expenses increased by $23 million compared to the prior year period. The majority of the increase relates to operating costs within acquired operations, primarily the Company’s Montreal acquisition. As a percent of revenue, operating expenses were 65.7% in the first quarter of 2014, as compared to 66.2% in the first quarter of 2013, an improvement of 50 basis points.

•    SG&A expenses improved by $15 million compared with the first quarter of 2013 and improved to 11.0% of revenue from 11.7% in the prior year period.

•    Net cash provided by operating activities was $584 million, an improvement of $7 million when compared to the first quarter of 2013, despite over $100 million in working capital headwinds from the payment of incentive compensation and the maturity of interest rate swaps related to a planned senior note issuance. Capital expenditures were $266 million. The Company had $166 million of divestiture proceeds in the quarter, primarily related to the sale of its China waste-to-energy joint venture.

•    Free cash flow increased $136 million to $484 million in the first quarter of 2014.^(b)

•    The Company returned $174 million to shareholders in the form of dividends.

•    The effective tax rate was approximately 29.6%. This rate was lower compared to the prior year due to a non-cash adjustment to deferred taxes resulting from a change in state tax law. The net effect of the benefit was a positive $0.02 per diluted share in the first quarter when compared to the first quarter of 2013.

Steiner concluded, “We are on target through the first quarter and encouraged by the positive momentum in our business. At the beginning of the year, we gave guidance that our 2014 free cash flow would exceed $1.3 billion. With our strong first quarter, we now expect to generate between $1.4 billion and $1.5 billion of free cash flow. With respect to the other elements of our initial full-year guidance, it is difficult to predict underlying business trends in the first quarter due to winter seasonality. However, early April volumes indicate a normal seasonal upturn, but it is only three weeks. After we see the effect on results from our seasonality through the full second quarter, we will likely refine our full-year guidance to reflect any underlying business trends.” ^(b)

(a)    For purposes of this press release, all references to “Net income” refer to the financial statement line item “Net income attributable to Waste Management, Inc.”

(b)    This press release includes adjusted net income and adjusted earnings per diluted share for the first quarter of 2013, which are non-GAAP measures as defined in Regulation G of the Securities Exchange Act of 1934, as amended, as well as a comparisons to first quarter of 2013 adjusted earnings per diluted share and adjusted income from operations margin. The Company reports its financial results in compliance with GAAP, but believes that also discussing non-GAAP measures provides investors with (i) additional, meaningful comparisons of current results to prior periods’ results by excluding items that the Company does not believe reflect its fundamental business performance and are not representative or indicative of our results of operations and (ii) financial measures the Company uses in the management of its business.

The Company’s projected full year 2014 earnings per diluted share are not based on GAAP net earnings per diluted share and are anticipated to be adjusted to exclude the effects of events or circumstances in 2014 that are not representative or indicative of the Company’s results of operations. Projected GAAP earnings per diluted share for the full year would require inclusion of the projected impact of future excluded items, including items that are not currently determinable, but may be significant, such as asset impairments and one-time items, charges, gains or losses from divestitures or litigation, or other items. Due to the uncertainty of the likelihood, amount and timing of any such items, the Company does not have information available to provide a quantitative reconciliation of adjusted projected full year earnings per diluted share to a GAAP earnings per diluted share projection.

The Company also discusses free cash flow and provides a projection of free cash flow, which is a non-GAAP measure, because it believes that it is indicative of our ability to pay our quarterly dividends, repurchase common stock, fund acquisitions and other investments and, in the absence of refinancings, to repay our debt obligations. Free cash flow is not intended to replace “Net cash provided by operating activities,” which is the most comparable U.S. GAAP measure. However, the Company believes free cash flow gives investors useful insight into how the Company views its liquidity. Nevertheless, the use of free cash flow as a liquidity measure has material limitations because it excludes certain expenditures that are required or that the Company has committed to, such as declared dividend payments and debt service requirements. The Company’s definition of free cash flow may not be comparable to similarly titled measures presented by other companies, and therefore is not subject to comparison. The Company defines free cash flow as:

•    Net cash provided by operating activities

•    Less, capital expenditures

•    Plus, proceeds from divestitures of businesses and other assets (net of cash divested).

The quantitative reconciliations of free cash flow for the quarter and adjusted first quarter of 2013 net income, earnings per diluted share, and income from operations margin to the most comparable GAAP measures are included in the accompanying schedules. Non-GAAP measures should not be considered a substitute for financial measures presented in accordance with GAAP, and investors are urged to take into account GAAP measures as well as non-GAAP measures in evaluating the Company.

The Company will host a conference call at 10:00 AM (Eastern) today to discuss the first quarter 2014 results. Information contained within this press release will be referenced and should be considered in conjunction with the call.
