GREENWICH, Conn. — October 18, 2011 — United Rentals, Inc. (NYSE: URI) today announced financial results for the third quarter 2011. Total revenue was $713 million and rental revenue was $604 million, compared with $605 million and $507 million, respectively, for the same period last year.

On a GAAP basis, the company reported third quarter 2011 net income of $65 million, or $0.91 per diluted share, compared with $23 million, or $0.33 per diluted share, for the same period last year. Adjusted EPS for the quarter, which excludes the impact of special items, was $0.92 per diluted share, compared with $0.40 per diluted share for the same period last year.

Third Quarter 2011 Highlights

	•		Rental revenue increased 19.1%, reflecting year-over-year increases of 7.5% in rental rates and 15.0% in the volume of equipment on rent. The company has updated its outlook for an increase in rental rates to about 6% for the full year.
	•		Time utilization was 73.5%, an increase of 2.2 percentage points from the same period last year, and a record high for the company. The company has raised its outlook for a full-year increase in time utilization to approximately 3.0 percentage points year-over-year.

	•		Adjusted EBITDA was $282 million, an increase of $66 million compared with the same period last year. Adjusted EBITDA margin was 39.6%, an increase of 3.9 percentage points compared with the same period last year, and a record for the company.

CEO Comments

Michael Kneeland, chief executive officer of United Rentals, said, “Our strong performance is evidence of a strategy that has become deeply rooted in our operations. The benefits of customer segmentation, price optimization, customer service differentiation and cost efficiency have begun to mesh in all areas of the business. This has put us in a position to act decisively on growth opportunities, such as the $219 million we invested in fleet in the quarter. Not only did this help to strengthen customer relationships and drive revenues, we also realized a historic high adjusted EBITDA margin of 39.6%.”

Kneeland continued, “While our customers remain bullish about construction activity next year and there is a deepening belief in rental penetration, our business model provides us with the flexibility to respond, as we have in the past, to anything we may experience in 2012.”

Nine Months 2011 Results

For the first nine months 2011, the company reported total revenue of $1,865 million and rental revenue of $1,562 million, compared with $1,640 million and $1,337 million, respectively, for the same period last year.

On a GAAP basis, the company reported income from continuing operations of $73 million, or $1.00 per diluted share, for the first nine months 2011, compared with a net loss of $5 million, or $0.09 per diluted share, for the same period last year. Adjusted EPS was $1.06 per diluted share, compared with $0.18 per diluted share last year. Adjusted EBITDA was $648 million, an increase of $138 million compared with the same period last year. Adjusted EBITDA margin was 34.7% for the first nine months 2011, an increase of 3.6 percentage points compared with the same period last year.

Free Cash Flow and Fleet Size

For the first nine months 2011, free cash usage was $(76) million, after total rental and non-rental capital expenditures of $655 million. By comparison, free cash flow for the first nine months last year was $144 million after total rental and non-rental capital expenditures of $307 million. Free cash flow for the first nine months 2010 included the receipt of a $55 million federal tax refund.

The company has updated its outlook for full year gross rental purchases and net rental capital expenditures. Gross rental purchases are now estimated to be approximately $775 million and net rental capital expenditures are expected to be in the range of $575 million to $600 million. Free cash flow is still expected to be between $5 million and $10 million.

The size of the rental fleet was $4.26 billion of original equipment cost at September 30, 2011, compared with $3.79 billion at December 31, 2010. The age of the rental fleet was 46.6 months on a unit-weighted basis at September 30, 2011, compared with 47.7 months at December 31, 2010.

Capital Markets Transactions

The company amended its accounts receivable securitization facility in September 2011 and its ABL facility in October 2011. The amended accounts receivable securitization facility provides for generally lower borrowing costs, a decrease in the facility size from $325 million to $300 million and adjustments to the receivables subject to purchase. The amended ABL facility provides for an increase in the facility size from $1.36 billion to $1.80 billion, an uncommitted incremental increase of up to $500 million in the size of the facility and generally lower borrowing costs.

Return on Invested Capital (ROIC)

Return on invested capital was 5.4% for the 12 months ended September 30, 2011, an increase of 2.2 percentage points from the same period last year. 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.

Conference Call

United Rentals will hold a conference call tomorrow, Wednesday, October 19, 2011, at 11:00 a.m. Eastern Time. The conference call will be available live by audio webcast at unitedrentals.com, where it will be archived, and by calling 866-835-8907.

Mr. Kneeland is also scheduled to appear on the FOX Business network on Wednesday, October 19, 2011, between 2:15 p.m. and 2:45 p.m., at which time he may discuss the company’s third quarter and nine month results as well as future expectations.

Non-GAAP Measures

Free cash (usage) 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, depreciation of rental equipment and non-rental depreciation and amortization. Adjusted EBITDA represents EBITDA plus the sum of the restructuring charge and stock compensation expense, net. Adjusted EPS represents EPS plus the sum of the restructuring and asset impairment charges and losses on the repurchase/redemption of debt securities and retirement of subordinated convertible debentures. 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 (usage) flow to a GAAP financial measure 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 can constrain our response 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 our equipment’s residual value; (13) inability to sell used fleet; (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; and (20) labor difficulties and potential enactment of new legislation affecting our labor relations and operations generally.

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) restructuring charge, (iii) loss on repurchase/redemption of debt securities and retirement of subordinated convertible debentures and (iv) asset impairment charge. Management believes adjusted earnings per share from continuing operations provides useful information concerning future profitability. However, adjusted earnings (loss) 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.

EBITDA AND ADJUSTED EBITDA GAAP RECONCILIATION
(In millions)

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, depreciation of rental equipment, and non-rental depreciation and amortization. Adjusted EBITDA represents EBITDA plus the sum of the 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.

We define free cash (usage) flow as (i) net cash provided by operating activities less (ii) purchases of rental and non-rental equipment plus (iii) proceeds from sales of rental and non-rental equipment and excess tax benefits from share-based payment arrangements, net. Management believes that free cash flow provides useful additional information concerning cash flow available to meet future debt service obligations and working capital requirements. However, free cash flow is not a measure of financial performance or liquidity under GAAP. Accordingly, free cash flow should not be considered an alternative to net income (loss) or cash flow from operating activities as an indicator of operating performance or liquidity. The table below provides a reconciliation between net cash provided by operating activities and free cash flow.
