Selected Business Highlights and Unaudited Financial Data

The company will delay finalizing its 2004 results and filing its Report on Form 10-K to allow additional time to review matters relating to the previously announced SEC fact-finding inquiry. The company believes this delay will extend beyond the Form 10-K due date, including the 15-day extension period. This delay will also give the company time to complete work on the income tax restatement and its evaluation and testing of internal controls and other items described below. The selected financial data and 2004 outlook provided in this press release are unaudited and subject to change based on completion of the audit or the outcome of the SEC inquiry or internal review.

CEO Comments on Performance and Outlook

Wayland Hicks, chief executive officer said, “2004 was an important year for United Rentals. We surpassed $3 billion of revenues for the first time and our free cash flow of $385 million was the highest in our company’s history. Our intense efforts to improve rental rates resulted in a 7.5% rate improvement in 2004, our highest annual increase.

“Our revenue growth of 8.4% continues to outpace our primary end market, private non-residential construction, which recovered 4% in 2004 according to Department of Commerce data. This achievement reflects strong revenue growth of 12.4% in our general rentals segment, partially offset by continued weakness in our traffic control segment.

“Our 2005 outlook is for total revenues of $3.4 billion. This outlook assumes 11% revenue growth in the general rentals segment, partially offset by a continued decline in our traffic control segment. Growth in general rentals is expected to be driven by continuing our rate initiatives, targeted for at least a 5% increase in rental rates; expanding our rental fleet; the planned opening of 30 to 35 new locations; and increasing contractor supplies revenues 25%. Our outlook assumes continued modest growth in non-residential construction which, despite growth in 2004, is still about 20% below peak historical levels.

“We’ll finalize our results as soon as possible. However, it’s important to take the extra time needed to review matters related to the SEC inquiry. In the interim, we have provided selected unaudited financial data that highlights our progress over the past year.

“We continue to feel positive about industry fundamentals and the direction of our business. We remain focused on our goals of driving revenue growth, improving our margins and increasing our return on capital. We plan to achieve these goals primarily through strong organic growth and new branch openings.”

SEC Non-Public Fact-Finding Inquiry

As previously announced, the SEC is conducting a non-public fact-finding inquiry of the company. The company is cooperating with the SEC, continues to provide information to the SEC and has formed a special committee of independent directors with separate counsel to review matters relating to the SEC inquiry. The inquiry appears to relate to a broad range of the company’s accounting practices and does not seem to be confined to a specific time period.

Restatement of Financial Results for Prior Periods to Reduce Income Tax Expense and Other Items

During testing of the company’s internal controls, as required by Section 404 of the Sarbanes-Oxley Act, the company determined that the provision for income taxes was higher than required for periods prior to 2004. The company has not finally determined the impact this will have on specific periods, but estimates the correction of this will result in a decrease in the provision for income taxes for prior years by a total of approximately $25 million, with a corresponding increase in net income.

The company expects that it will restate its financial statements for the years 1999 through 2003 to correct the income tax provision. Accordingly, investors are cautioned not to rely on the company’s historical financial statements. For additional information, please refer to the company’s Current Report on Form 8-K filed with the SEC on March 14, 2005.

The company has determined that the control deficiencies that resulted in the income tax provision being higher than required represented a material weakness in the company’s internal controls over financial reporting at December 31, 2004. The company believes that it has taken adequate measures to remedy this weakness.

As previously reported, the company identified a material weakness in the third quarter partially relating to its self-insurance reserve estimation and evaluation process. The company is conducting additional testing of the process and reserve levels in 2004 and prior periods.

The company is also evaluating whether a material weakness exists relating to a deficiency in reconciling physical inventory quantities to accounting records for certain types of bulk rental equipment inventory, which had an unreconciled difference of approximately $4 million.

The company does not believe that any deficiency that has been identified, including the ones noted above, would adversely impact the 2004 outlook or the selected unaudited financial data provided in this press release. However, the company’s evaluation and testing of internal controls, including testing of any remediation of deficiencies, has not yet been completed. There can be no assurance as to the outcome of this testing or that additional material weaknesses will not be identified or adjustments required.

Additional Information Related to the Delay in Filing Form 10-K

The company anticipates obtaining a waiver from the lenders under its secured credit facility of certain defaults arising from the delay in filing its Form 10-K. However, there can be no assurance of this and, if the waiver is not obtained, the lenders may require immediate repayment of all outstanding borrowings. Furthermore, the requisite percentage of holders of various other securities issued by the company, or the trustee under the applicable indenture, could elect to declare an event of default based on the delay in filing the Form 10-K. In this event, if the company were unable to obtain a waiver or effect a cure within the applicable grace period, these holders or the trustee could accelerate the maturity of the debt. For additional information, please refer to the company’s Current Report on Form 8-K filed with the SEC on March 14, 2005.

Conference Call

United Rentals will hold a conference call with Wayland Hicks, chief executive officer, and John Milne, president and chief financial officer, today, Monday, March 14, at 11:00 am Eastern Time. The conference will be available live by audio webcast at www.unitedrentals.com, where it will be archived.

GAAP Reconciliation

We define “free cash flow” as (i) net cash provided by operating activities plus (ii) proceeds from sales of rental equipment and, during 2004 proceeds from the sale of real estate less (iii) aggregate expenditures for purchase of rental equipment and other property and equipment. Our free cash flow was $385.1 million and $145.7 million during 2004 and 2003, respectively. Free cash flow is presented to provide 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 Generally Accepted Accounting Principles (“GAAP”). Accordingly, free cash flow should not be considered an alternative to net income or cash flow from operating activities as indicators of operating performance or liquidity. The table below provides a reconciliation between unaudited net cash provided by operating activities and free cash flow for the periods indicated (in millions):

	Year Ended
	2004			2003
Net cash provided by operating activities	$	761.0		$	342.3
Purchases of rental equipment		(577.2	)		(335.9	)
Purchases of property and equipment		(57.4	)		(42.0	)
Proceeds from sales of rental equipment		235.2			181.3
Proceeds from real estate sale-leaseback		23.5			—
Free cash flow	$	385.1		$	145.7
