Covanta Holding Corporation Reports 2007 Fourth Quarter and Full-Year Results and Establishes 2008 Guidance

Covanta Holding Corporation (NYSE: CVA ) reported financial results today for the three and twelve months ended December 31, 2007. Diluted earnings per share was $0.47 in the fourth quarter of 2007, which compares to diluted earnings per share of $0.08 in the prior year comparative period. For the full year 2007, diluted earnings per share was $0.85, up from $0.72 in the prior year.

Fourth Quarter Results

For the three months ended December 31, 2007, operating revenues grew 24 percent to $395 million, up from $318 million in the prior year comparative period. The increase was driven by construction revenues from the Hillsborough County facility expansion, revenue from domestic acquisitions completed in 2007, higher prices for domestic waste disposal services, and increased electricity sales at two facilities located in India.

Net income was $72 million for the quarter, up from $12 million in the prior year comparative period. This increase was impacted by lower interest expense, resulting from the recapitalization completed in early 2007, and a lower effective tax rate, driven primarily by the release of a valuation allowance. Cash Flow Provided by Operating Activities ("Operating Cash Flow") was $98 million in the fourth quarter. Adjusted EBITDA at the Company's principal subsidiary, Covanta Energy Corporation ("Covanta Energy"), was $155 million.

Full-Year 2007 Results

For the twelve months ended December 31, 2007, operating revenues rose 13 percent to $1.43 billion, up from $1.27 billion in 2006. The Company's domestic segment operating revenues grew by 11 percent to $1.25 billion for the year, driven primarily by the Hillsborough County facility expansion, revenue from domestic acquisitions completed in 2007, higher pricing on recycled metal sales, and higher electricity rates. International revenues grew by 29 percent to $177 million primarily due to increased electricity sales at the two facilities in India.

Net income grew 23 percent to $131 million, up from $106 million in 2006. This increase was impacted by lower interest expense and a lower effective tax rate. Operating Cash Flow was $358 million for the year. Covanta Energy's Adjusted EBITDA was $552 million.

The Company incurred $86 million of capital expenditures in 2007, which included $18 million related to the SEMASS fire, $12 million of capital improvements at facilities acquired during the year, and $55 million primarily to maintain existing facilities. In addition, the Company repaid $164 million of project debt and invested $110 million in acquisitions and $11 million in equity interests. In total, the Company reinvested all of its Operating Cash Flow back into the business.

"2007 was a milestone year for Covanta, as we made significant progress towards our strategic goals," said Anthony Orlando, President and Chief Executive Officer of Covanta. "We recapitalized our balance sheet to provide the financial flexibility to seize growth opportunities, successfully integrated several acquisitions to complement our domestic fleet, and we established platforms to expand our energy-from-waste business in Europe and China. In addition, we extended our track record of consistent operational performance, safely converting 15 million tons of waste into clean, renewable energy for our clients, while again generating strong financial results within or above our guidance ranges."

2008 Guidance

The Company is establishing guidance for 2008 for the following key metrics:

-- Adjusted EBITDA of $550 million to $575 million;

-- Diluted earnings per share of $0.90 to $1.00; and

-- Operating Cash Flow in the range of $380 million to $420 million.

For simplicity, guidance for 2008 is now being provided entirely for Covanta Holding Corporation. See the "Discussion of Non-GAAP Financial Measures" which follows the exhibits.

    (A) Certain prior period amounts have been reclassified to conform to
        current period presentation.

    (B) On March 31, 2007, the SEMASS energy-from-waste facility experienced a
        fire in the front-end receiving portion of the facility. Damage was
        extensive to this portion of the facility and operations at the
        facility were suspended completely for approximately 20 days. As a
        result of this loss, Covanta recorded an asset impairment of $17.3
        million, pre-tax, during the year ended December 31, 2007, which
        represented the net book value of the assets destroyed.

        The cost of repair or replacement, and business interruption losses,
        are insured under the terms of applicable insurance policies, subject
        to deductibles. Covanta cannot predict the timing of when it will
        receive the proceeds under such policies. During the year ended
        December 31, 2007, Covanta recorded insurance recoveries of $17.3
        million related to repair and reconstruction, $2.7 million related to
        clean-up costs and $2.0 million related to business interruption
        losses. Insurance recoveries are recorded as a reduction to the loss
        related to the write-down of assets where such recoveries relate to
        repair and reconstruction costs, or as a reduction to operating
        expenses where such recoveries relate to other costs or business
        interruption losses. Covanta expects the cost of repair or replacement
        and business interruption losses it does not recover, representing
        deductibles under such policies, will not be material.

    © During the first quarter in 2007, Covanta completed public offerings
        of common stock and 1.00% Senior Convertible Debentures, and Covanta
        Energy closed on new credit facilities. In addition, Covanta Energy
        completed tender offers for outstanding notes previously issued by its
        intermediate subsidiaries. As a result of the recapitalization,
        Covanta recognized a loss on extinguishment of debt charge of
        approximately $32.1 million, pre-tax, which was comprised of the
        write-down of deferred financing costs, tender premiums paid for the
        intermediate subsidiary debt, and a call premium paid for a credit
        facility refinanced, which was in effect prior to Covanta Energy's new
        credit facilities. These amounts were partially offset by the write-
        down of unamortized premiums relating to the intermediate subsidiary
        debt and a gain associated with the settlement of interest rate swap
        agreements.

        As a result of amendments to Covanta Energy's financing arrangements
        in May 2006, Covanta recognized a loss on extinguishment of debt of
        $6.8 million, pre-tax, which was comprised of the write-down of
        deferred financing costs and a call premium paid on the
        extinguishment.

    (1) Covanta is a minority shareholder in the "Quezon Project Company" that
        owns the Quezon Power, Inc. ("Quezon") facility in the Philippines. In
        June 2006, the Philippine tax authorities issued a ruling clarifying
        the deductibility of unrealized foreign exchange losses to the Quezon
        Project Company. As a result, the Quezon Project Company recorded a
        cumulative deferred income tax benefit which increased Covanta's
        equity in net income from unconsolidated investments by $7 million or
        5 cents per diluted share. The impact of this ruling, on periods
        subsequent to the quarter ended June 30, 2006, is based on the
        fluctuations in the value of the Philippine peso versus the US dollar
        in those respective periods.

    (2) This amount represents plant operating expenses, net of business
        interruption insurance recoveries related to the SEMASS fire, but
        excludes lost revenue during the restoration of the SEMASS energy-
        from-waste facility.

    (A) These items represent amounts that are non-cash in nature.

    (B) On March 31, 2007, the SEMASS energy-from-waste facility experienced a
        fire in the front-end receiving portion of the facility. Damage was
        extensive to this portion of the facility and operations at the
        facility were suspended completely for approximately 20 days. As a
        result of this loss, Covanta recorded an asset impairment of $17.3
        million, pre-tax, during the year ended December 31, 2007, which
        represented the net book value of the assets destroyed.

        The cost of repair or replacement, and business interruption losses,
        are insured under the terms of applicable insurance policies, subject
        to deductibles. Covanta cannot predict the timing of when it will
        receive the proceeds under such policies. During the year ended
        December 31, 2007, Covanta recorded insurance recoveries of $17.3
        million related to repair and reconstruction, $2.7 million related to
        clean-up costs and $2.0 million related to business interruption
        losses. Insurance recoveries are recorded as a reduction to the loss
        related to the write-down of assets where such recoveries relate to
        repair and reconstruction costs, or as a reduction to operating
        expenses where such recoveries relate to other costs or business
        interruption losses. Covanta expects the cost of repair or replacement
        and business interruption losses it does not recover, representing
        deductibles under such policies, will not be material.

    © During the first quarter in 2007, Covanta completed public offerings
        of common stock and 1.00% Senior Convertible Debentures, and Covanta
        Energy closed on new credit facilities. In addition, Covanta Energy
        completed tender offers for outstanding notes previously issued by its
        intermediate subsidiaries.  As a result of the recapitalization,
        Covanta recognized a loss on extinguishment of debt charge of
        approximately $32.1 million, pre-tax, which was comprised of the
        write-down of deferred financing costs, tender premiums paid for the
        intermediate subsidiary debt, and a call premium paid for a credit
        facility refinanced, which was in effect prior to Covanta Energy's new
        credit facilities.  These amounts were partially offset by the write-
        down of unamortized premiums relating to the intermediate subsidiary
        debt and a gain associated with the settlement of interest rate swap
        agreements.

        As a result of amendments to Covanta Energy's financing arrangements
        in May 2006, Covanta recognized a loss on extinguishment of debt of
        $6.8 million, pre-tax, which was comprised of the write-down of
        deferred financing costs and a call premium paid on the
        extinguishment.

    (D)  The components of Adjusted EBITDA are as follows:

    (A) Purchase of property, plant and equipment is also referred to as
        Capital Expenditures.

    (B) During the twelve months ended December 31, 2007, Capital Expenditures
        were incurred that related to the repair and replacement of assets at
        the SEMASS energy-from-waste facility that were damaged by a fire on
        March 31, 2007. The cost of repair or replacement is insured under the
        terms of the applicable insurance policy, subject to deductibles.
        Covanta cannot predict the timing of when all proceeds under such
        policy will be received. During 2007, Covanta received $9.4 million in
        insurance proceeds related to property damage and is included as
        Property Insurance Proceeds in the investing activities section of
        Covanta's statement of cash flows for the twelve months ended December
        31, 2007. Covanta expects the cost of repair or replacement not
        recovered, representing deductibles under such policy, will not be
        material.

    © During the twelve months ended December 31, 2007, Capital Expenditures
        were incurred at three facilities that Covanta acquired in 2007
        primarily to improve the productivity or environmental performance of
        those facilities. The majority of these expenditures were incurred at
        the two California biomass facilities acquired in July 2007. In total,
        Covanta plans to invest between $15 and $20 million in capital
        improvements at the biomass facilities, of which between $7 and $12
        million remains to be incurred in 2008. Although, in accordance with
        GAAP, this spending will be recorded as a component of purchase of
        property, plant and equipment on Covanta's statement of cash flows,
        management considers this spending as a component of the cost to
        acquire these businesses since these major capital improvements are
        required to achieve desired facility performance.

    (D) Capital expenditures primarily to maintain existing facilities.

        debt and a gain associated with the settlement of interest rate swap
        agreements.

        As a result of amendments to Covanta Energy's financing arrangements
        in May 2006, Covanta recognized a loss on extinguishment of debt of
        $6.8 million, pre-tax, which was comprised of the write-down of
        deferred financing costs and a call premium paid on the
        extinguishment.


    © Covanta is a minority shareholder in the "Quezon Project Company" that
        owns the Quezon Power, Inc. ("Quezon") facility in the Philippines.
        In June 2006, the Philippine tax authorities issued a ruling
        clarifying the deductibility of unrealized foreign exchange losses to
        the Quezon Project Company. As a result, the Quezon Project Company
        recorded a cumulative deferred income tax benefit which increased
        Covanta's equity in net income from unconsolidated investments by $7
        million or 5 cents per diluted share. The impact of this ruling, on
        periods subsequent to the quarter ended June 30, 2006, is based on the
        fluctuations in the value of the Philippine peso versus the US dollar
        in those respective periods.

    (D) During the quarter ended June 30, 2006, consistent with its strategy
        to pursue international investment opportunities, Covanta adopted the
        permanent reinvestment exception under APB 23 with respect to the
        earnings of its foreign subsidiaries. Pursuant to this election,
        Covanta now considers foreign earnings to be permanently reinvested
        and, as a result, Covanta recorded a catch-up, cumulative adjustment
        in the second quarter of 2006 of $10 million or 7 cents per diluted
        share to reflect the reversal of the deferred taxes that were accrued
        over the last two years prior to the election under APB 23.

Discussion of Non-GAAP Financial Measures

To supplement our results prepared in accordance with United States generally accepted accounting principles ("GAAP"), we use the measure of Adjusted EBITDA, which is a non-GAAP measure as defined by the Securities and Exchange Commission. The non-GAAP financial measure of Adjusted EBITDA described below, and used in the tables above, is not intended as a substitute and should not be considered in isolation from measures of financial performance or liquidity prepared in accordance with GAAP. In addition, our non-GAAP financial measure may be different from non-GAAP measures used by other companies, limiting their usefulness for comparison purposes.

We use a number of different financial measures, both GAAP and non-GAAP, in assessing the overall performance of our business. We use Adjusted EBITDA to provide further information that is useful to an understanding of the financial covenants contained in the credit facilities of our most significant subsidiary, Covanta Energy Corporation, and as additional ways of viewing aspects of its operations that, when viewed with the GAAP results and the accompanying reconciliations to corresponding GAAP financial measures, provide a more complete understanding of our business. The presentation of Adjusted EBITDA is intended to enhance the usefulness of our financial information by providing a measure which management internally uses to assess and evaluate the overall performance of its business and those of possible acquisition candidates, and highlight trends in the overall business. We also use this non-GAAP financial measure as a significant criterion of performance-based components of employee compensation.

Adjusted EBITDA should not be considered as an alternative to net income or an alternative to cash flow provided by operating activities as indicators of our performance or liquidity or any other measures of performance or liquidity derived in accordance with GAAP.

Adjusted EBITDA

The calculation of Adjusted EBITDA is based on the definition in Covanta Energy's credit facilities, which we have guaranteed. Adjusted EBITDA is defined as earnings before interest, taxes, depreciation and amortization, as adjusted for additional items subtracted from or added to net income. Because our business is substantially comprised of that of Covanta Energy, our financial performance is substantially similar to that of Covanta Energy. For this reason, and in order to avoid use of multiple financial measures which are not all from the same entity, the calculation of Adjusted EBITDA and other financial measures presented herein are ours, measured on a consolidated basis.

Under these credit facilities, Covanta Energy is required to satisfy certain financial covenants, including certain ratios of which Adjusted EBITDA is an important component. Compliance with such financial covenants is expected to be the principal limiting factor which will affect our ability to engage in a broad range of activities in furtherance of our business, including making certain investments, acquiring businesses and incurring additional debt. Covanta Energy was in compliance with these covenants as of December 31, 2007. Failure to comply with such financial covenants could result in a default under these credit facilities, which default would have a material adverse affect on our financial condition and liquidity.

These financial covenants are measured on a trailing four quarter period basis and the material covenants are as follows:

-- maximum Covanta Energy leverage ratio of 4.25 to 1.00 (which declines for quarterly periods after September 30, 2008), which measures Covanta Energy's Consolidated Adjusted Debt, (which is the principal amount of its consolidated debt less certain restricted funds dedicated to repayment of project debt principal and construction costs) to its Adjusted EBITDA; and

-- minimum Covanta Energy interest coverage ratio of 3.00 to 1.00, which measures Covanta Energy's Adjusted EBITDA to its consolidated interest expense plus certain interest expense of ours, to the extent paid by Covanta Energy.

In order to provide a meaningful basis for comparison, we are providing information with respect to our Adjusted EBITDA for the twelve months ended December 31, 2007 and 2006, reconciled for each such period to net income and cash flow provided by operating activities, which are believed to be the most directly comparable measures under GAAP.
