2011 Highlights

2012 Standalone Outlook³

The company provided the following outlook for the full year 2012:

CEO Comments

Michael Kneeland, chief executive officer of United Rentals, said, “The fourth quarter marked a strong end to a stellar year for our company, particularly in light of the sluggish economy. Once again, we drove rental revenue ahead of the construction recovery through a combination of rate improvement and record time utilization on a larger fleet. The fundamentals of our growth are rock solid: our strategic focus on customer service excellence, rigorous efficiency and rental rate expansion. I’m very proud of the way our employees have delivered in all of these areas. Through their efforts, we are in an excellent position to capitalize on the emerging up-cycle as well as the broader secular shift toward equipment rental.”

Kneeland continued, “We are tremendously excited about the opportunities of 2012, which we expect will be a transformative year for United Rentals. We’re making good progress on all fronts toward our intended acquisition of RSC and the integration planning. With our markets in recovery, the timing is ideal to combine these two companies into a best-in-class United Rentals with a wealth of best practices for value creation.”

2011 Financial Results

For the full year 2011, on a GAAP basis, the company reported income from continuing operations of $101 million, or $1.38 per diluted share, compared with a loss of $22 million, or $0.38 per diluted share, for 2010. On an adjusted basis, excluding the impact of special items, EPS for the full year 2011 was $1.87 per diluted share, compared with $0.33 per diluted share in 2010. The effective tax rate for the full year 2011 was 38.4%.

The company’s continuing operations EPS and adjusted EPS for the fourth quarter and full year 2011 include an $8 million benefit ($5 million after-tax) related to the reduction of the company’s self-insurance reserves, as compared to an $18 million charge ($11 million after-tax) in the fourth quarter and full year 2010.

Free Cash Flow and Fleet Size

For the full year 2011, free cash flow, a non-GAAP measure, was $23 million, compared with free cash flow of $227 million for the full year 2010. The year-over-year decrease in free cash flow was largely the result of an increase in net rental capital expenditures, partially offset by improved cash flows from operating activities.

The size of the rental fleet, as measured by the original equipment cost, was $4.29 billion at December 31, 2011, compared with $3.79 billion at December 31, 2010. The age of the rental fleet was 46.4 months on a unit-weighted basis at December 31, 2011, compared with 47.7 months at December 31, 2010.

Return on Invested Capital (ROIC)

The company’s ROIC metric uses after-tax operating income for the trailing 12 months divided by the averages of stockholders’ equity (deficit), debt and deferred taxes, net of average cash. To mitigate the volatility related to fluctuations in the company’s tax rate from period to period, the federal statutory tax rate of 35% is used to calculate after-tax operating income. The company’s ROIC was 6.7% for the 12 months ended December 31, 2011, an increase of 3.0 percentage points from the same date in 2010.

Announced Merger with RSC Holdings

On December 15, 2011, United Rentals entered into a definitive merger agreement with RSC Holdings (RSC), pursuant to which United Rentals will acquire RSC in a cash-and-stock transaction valued at $18.00 per share, or a total enterprise value of $4.2 billion, based on the market price for URI common stock at the time the transaction was announced. Upon the closing of the transaction, each outstanding share of RSC common stock will be converted into the right to receive $10.80 in cash and 0.2783 of a share of United Rentals common stock, subject to the terms and conditions of the merger agreement. The cash portion of the transaction will be financed through new debt issuance and drawing on current loan facilities. United Rentals has obtained financing commitments from Morgan Stanley Senior Funding Inc., Bank of America Merrill Lynch, Wells Fargo, Credit Suisse AG, The Bank of Nova Scotia and HSBC Bank USA, N.A. in support of this transaction. United Rentals intends to re-pay the outstanding amounts on RSC’s existing senior secured debt, and assume all of RSC’s existing unsecured debt. The proposed transaction is subject to the delivery of a solvency opinion as well as customary closing conditions, including approval by United Rentals and RSC stockholders and expiration or termination of the waiting period under the Canada Competition Act. United Rentals and RSC expect the transaction to close in the first half of 2012.

Conference Call

United Rentals will hold a conference call tomorrow, Thursday, January 26, 2012, at 12:00 p.m. Eastern Time. The conference call will be available live by audio webcast at unitedrentals.com, where it will be archived until the next earnings call, and by calling 866-219-5894.

Non-GAAP Measures

Free cash flow, earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted EBITDA, and adjusted earnings per share (adjusted EPS) are non-GAAP financial measures as defined under the rules of the SEC. Free cash flow represents net cash provided by operating activities, less purchases of rental and non-rental equipment plus proceeds from sales of rental and non-rental equipment and excess tax benefits from share-based payment arrangements, net. EBITDA represents the sum of net income (loss), loss from discontinued operation, net of taxes, provision (benefit) for income taxes, interest expense, net, interest expense-subordinated convertible debentures, net, depreciation of rental equipment and non-rental depreciation and amortization. Adjusted EBITDA represents EBITDA plus the sum of the RSC merger related costs, the restructuring charge and stock compensation expense, net. Adjusted EPS represents EPS plus the sum of the RSC merger related costs, the restructuring charge, the gains/losses on the repurchase/redemption of debt securities and retirement of subordinated convertible debentures and ABL amendment, and the asset impairment

charge. The company believes that: (i) free cash flow provides useful additional information concerning cash flow available to meet future debt service obligations and working capital requirements; (ii) EBITDA and adjusted EBITDA provide useful information about operating performance and period-over-period growth; and (iii) adjusted EPS provides useful information concerning future profitability. However, none of these measures should be considered as alternatives to net income, cash flows from operating activities or earnings per share under GAAP as indicators of operating performance or liquidity. Information reconciling forward-looking free cash flow and Adjusted EBITDA to GAAP financial measures is unavailable to the company without unreasonable effort.

Factors that could cause actual results to differ materially from those projected include, but are not limited to, the following: (1) a slowdown in the recovery of North American construction and industrial activities, which decreased during the economic downturn and significantly affected our revenues and profitability, may further reduce demand for equipment and prices that we can charge; (2) a decrease in levels of infrastructure spending, including lower than expected government funding for stimulus-related construction projects; (3) our highly leveraged capital structure, which requires us to use a substantial portion of our cash flow for debt service and can constrain our flexibility in responding to unanticipated or adverse business conditions; (4) restrictive covenants in our debt agreements, which could limit our financial and operation flexibility; (5) noncompliance with covenants in our debt agreements, which could result in termination of our credit facilities and acceleration of outstanding borrowings; (6) inability to access the capital that our business may require; (7) inability to collect on contracts with customers; (8) incurrence of impairment charges; (9) the potential consequences of litigation and other claims relating to our business, including certain claims that our insurance may not cover; (10) an increase in our loss reserves to address business operations or other claims and any claims that exceed our established levels of reserves; (11) incurrence of additional costs and expenses in connection with litigation, regulatory or investigatory matters; (12) increases in our maintenance and replacement costs as we age our fleet, and decreases in the residual value of our equipment; (13) inability to sell our new or used fleet in the amounts, or at the prices, we expect; (14) challenges associated with past or future acquisitions, such as undiscovered liabilities and integration issues; (15) management turnover and inability to attract and retain key personnel; (16) our rates and time utilization being less than anticipated; (17) our costs being more than anticipated, the inability to realize expected savings and the inability to obtain key equipment and supplies; (18) disruptions in our information technology systems; (19) competition from existing and new competitors; (20) labor difficulties and labor-based legislation affecting labor relations and operations generally; (21) the inability of United Rentals and RSC to obtain stockholder or regulatory approvals required for the proposed transaction or the imposition of conditions that could reduce the anticipated

UNITED RENTALS, INC.

ADJUSTED EARNINGS PER SHARE GAAP RECONCILIATION

We define “Earnings per share from continuing operations—adjusted” as the sum of (i) earnings (loss) per share from continuing operations—GAAP, as reported plus the after-tax impacts of (ii) RSC merger related costs, (iii) restructuring charge, (iv) losses on repurchase/redemption of debt securities and retirement of subordinated convertible debentures and ABL amendment and (v) asset impairment charge. Management believes adjusted earnings per share from continuing operations provides useful information concerning future profitability. However, adjusted earnings per share from continuing operations is not a measure of financial performance under GAAP. Accordingly, adjusted earnings per share from continuing operations should not be considered an alternative to GAAP earnings (loss) per share from continuing operations. The table below provides a reconciliation between earnings (loss) per share from continuing operations—GAAP, as reported, and earnings per share from continuing operations—adjusted.

UNITED RENTALS, INC.

EBITDA AND ADJUSTED EBITDA GAAP RECONCILIATION

(In millions)

EBITDA represents the sum of net income (loss), (income) loss from discontinued operation, net of taxes, provision (benefit) for income taxes, interest expense, net, interest expense-subordinated convertible debentures, net, depreciation of rental equipment, and non-rental depreciation and amortization. Adjusted EBITDA represents EBITDA plus the sum of the RSC merger related costs, restructuring charge, and stock compensation expense, net. These items are excluded from adjusted EBITDA internally when evaluating our operating performance and allow investors to make a more meaningful comparison between our core business operating results over different periods of time, as well as with those of other similar companies. Management believes that EBITDA and adjusted EBITDA, when viewed with the Company's results under GAAP and the accompanying reconciliation, provide useful information about operating performance and period-over-period growth, and provide additional information that is useful for evaluating the operating performance of our core business without regard to potential distortions. Additionally, management believes that EBITDA and adjusted EBITDA permit investors to gain an understanding of the factors and trends affecting our ongoing cash earnings, from which capital investments are made and debt is serviced. However, EBITDA and adjusted EBITDA are not measures of financial performance or liquidity under GAAP and, accordingly, should not be considered as alternatives to net income (loss) or cash flow from operating activities as indicators of operating performance or liquidity. The table below provides a reconciliation between net income (loss) and EBITDA and adjusted EBITDA.
