United Rentals Announces First Quarter 2012 Results

GREENWICH, Conn.—April 17, 2012—United Rentals, Inc. (NYSE: URI) today announced financial results for the first quarter 2012. Total revenue was $656 million and rental revenue was $523 million, compared with $523 million and $434 million, respectively, for the same period last year. Adjusted EBITDA¹ was $231 million and adjusted EBITDA margin was 35.2% for the first quarter 2012, an increase of $86 million and 7.5 percentage points over last year.

On a GAAP basis, the company reported first quarter 2012 net income of $13 million, or $0.17 per diluted share, compared with a net loss of $20 million, or $0.34 per diluted share, for the same period in 2011. Adjusted EPS² for the quarter was $0.36 per diluted share, compared with a loss of $0.32 per diluted share the prior year.

First Quarter 2012 Highlights³

CEO Comments

Michael Kneeland, chief executive officer of United Rentals, said, “Our performance surpassed all prior first quarters, with record time utilization, record fleet growth, and record adjusted EBITDA, both dollars and margin. Once again, we drove profitable growth faster than the construction recovery. Both core areas of our business—general rentals and specialty operations—realized higher rates year-over-year on a fleet that was about $600 million larger on average. These results speak volumes about the effectiveness of our strategy and the ongoing secular shift toward renting.”

Kneeland continued, “Current market dynamics create a favorable environment for our combination with RSC. We expect to complete the transaction on April 30, and move immediately into integration mode. The benefits are substantial, including more than $200 million in cost synergies, an unparalleled branch footprint, and significant penetration into the industrial sector.”

Free Cash Flow and Fleet Size

For the first quarter 2012, free cash usage (negative flow) was $89 million, after total rental and non-rental capital expenditures of $426 million. By comparison, free cash flow for the first quarter 2011 was $70 million after total rental and non-rental capital expenditures of $120 million. The company has reaffirmed its standalone outlook for full year 2012 free cash usage in the range of $50 million to $100 million. Additionally, the company updated its standalone outlook for net rental capital expenditures of between $700 million and $750 million, after gross purchases of approximately $1.0 billion.

The size of the rental fleet was $4.31 billion of original equipment cost at March 31, 2012, compared with $4.05 billion at December 31, 2011. The age of the rental fleet was 47.3 months on an OEC-weighted basis at March 31, 2012, compared with 50.3 months at December 31, 2011.

Return on Invested Capital (ROIC)

Return on invested capital was 7.7% for the 12 months ended March 31, 2012, an increase of 3.4 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), debt⁴ 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.

Announced Merger with RSC Holdings

On December 15, 2011, the company entered into a definitive merger agreement with RSC Holdings, Inc. (RSC), pursuant to which the company agreed to acquire RSC in a cash-and-stock transaction that ascribed a total enterprise value of $4.2 billion to RSC. The cash portion of the merger consideration and transaction fees and expenses will be paid with the net proceeds from the company’s wholly owned subsidiary URI Financing Escrow Corporation’s recent senior secured notes and senior notes offerings.

After paying the cash portion of the merger consideration, the company will use the net proceeds from the sale of the senior secured notes and senior notes to repay and discharge certain of RSC’s indebtedness and pay related transaction fees and expenses. In connection with the proposed transaction, the company will assume all of RSC’s remaining debt, which totaled $947 million as of March 31, 2012.

The proposed transaction remains subject to approval by United Rentals’ stockholders and RSC’s stockholders and other customary closing conditions. United Rentals and RSC will each hold special meetings on April 27, 2012, at which their respective stockholders will vote on whether to approve the merger and related matters. Subject to receipt of these stockholder approvals and satisfaction of certain other closing conditions, the company anticipates that the proposed transaction will close on April 30, 2012.

Conference Call

United Rentals will hold a conference call tomorrow, Wednesday, April 18, 2012, 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 until the next earnings call, and by calling 866-261-7147.

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. EBITDA represents the sum of net income (loss), 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 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 loss on the retirement of subordinated convertible debentures and the RSC merger related interest expense. 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.

UNITED RENTALS, INC.

ADJUSTED EARNINGS PER SHARE GAAP RECONCILIATION

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

UNITED RENTALS, INC.

EBITDA AND ADJUSTED EBITDA GAAP RECONCILIATION

(In millions)

EBITDA represents the sum of net income (loss), 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 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.

FREE CASH FLOW GAAP RECONCILIATION

(In millions)

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. 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 (usage) flow.
