SCOTTSDALE, Ariz., April 20, 2011 — RSC Holdings Inc.

Adjusted EBITDA was $99 million for the quarter, compared with $66 million for the same period last year. Adjusted EBITDA margin was 30.2% for the first quarter, compared with 25.3% in 2010. The change in profitability and margins primarily reflects increased volume and improved pricing.

CEO Comments

Erik Olsson, President and Chief Executive Officer, stated: “We produced another quarter of exceptional volume growth of 20% and generated positive year-over-year pricing of 2.0%, including a 3.8% year-over-year improvement in March. These results drove a 50% year-over-year increase in EBITDA and demonstrate the continued and increasing acceptance of our leading value proposition by both industrial and non-residential construction customers. Our strategy of making consistent investments in our footprint, people, technology and sales organization throughout the downturn has positioned us to outpace the growth of our end markets as we enter the expansion phase of the business cycle.”

Outlook for 2Q11

Business activity in the company’s primary end-market, industrial and non-construction, improved on a year-over-year basis in the first quarter, while the non-residential construction end market, which makes up 35% of RSC revenues, declined at a moderating pace. These trends are anticipated to continue and RSC expects double-digit volume growth in the second quarter. In addition, the company expects utilization levels to be considerably higher than those seen in the prior year quarter and in the first quarter of 2011 with favorable year-over-year rental rates.

Mr. Olsson concluded: “We see continued strengthening in the industrial markets and are benefiting from increasing customer focus on the total cost of rental and not strictly pricing. Customers are embracing the value of our total rental solution approach including our Total Control® system. In addition, improved results were widespread with all regions delivering double digit revenue growth. As a result, we expect continued favorable year-over-year comparisons in the second quarter and remain optimistic that these positive trends will continue throughout the year.”

Annex A

EBITDA and Adjusted EBITDA. EBITDA, a supplemental non-GAAP financial measure, is defined as consolidated net income (loss) before net interest expense, income taxes and depreciation and amortization. Adjusted EBITDA as presented herein is a non-GAAP financial measure and is defined as consolidated net income (loss) before net interest expense, income taxes, and depreciation and amortization and before certain other items, including loss on extinguishment of debt, share-based compensation, and other (income) expense, net. All companies do not calculate EBITDA and Adjusted EBITDA in the same manner, and RSC Holdings’ presentation may not be comparable to those presented by other companies.

The company presents EBITDA and Adjusted EBITDA in this release because it believes these calculations are useful to investors in evaluating our financial performance and as a liquidity measure. However, EBITDA and Adjusted EBITDA are not recognized measurements under GAAP, and when analyzing the company’s performance, investors should use EBITDA and Adjusted EBITDA in addition to, and not as an alternative to, net income (loss) or net cash provided by operating activities as defined under GAAP.

Free cash flow. The company defines free cash flow as net cash provided by operating activities and net capital inflows (expenditures). All companies do not calculate free cash flow in the same manner, and RSC Holdings’ presentation may not be comparable to those presented by other companies. We believe free cash flow provides useful additional information concerning cash flow available to meet future debt service obligations and working capital needs. However, free cash flow is a non-GAAP measure and should be used in addition to, and not as an alternative to, data presented in accordance with GAAP.

The accompanying tables reconcile the GAAP financial measures that are most directly comparable to these non-GAAP financial measures.

Statistical Measures

Fleet utilization is defined as the average aggregate dollar value of equipment rented by customers (based on original equipment fleet cost) during the relevant period divided by the average aggregate dollar value of all equipment owned (based on original equipment fleet cost) during the relevant period.

Average fleet age at period end is the number of months since an equipment unit was first placed in service, weighted by multiplying individual equipment ages by their respective original costs and dividing the sum of those individual calculations by the total original cost. Equipment refurbished by the original equipment manufacturer is considered new.

Same store rental revenue growth/(decline) is calculated as the year-over-year change in rental revenue for locations that are open at the end of the period reported and have been operating under the company’s direction for more than 12 months.

Employee count is given as of the end of the period indicated and the data reflects the actual head count as of each period presented.

Original Equipment Fleet Cost (OEC) is defined as the original dollar value of rental equipment purchased from the original equipment manufacturer (OEM). Fleet purchased from non-OEM sources is assigned a comparable OEC dollar value at the time of purchase.

Return on operating capital employed (ROCE) is calculated by dividing operating income (excluding transaction costs, management fees, and amortization of intangibles) for the preceding twelve months by the average operating capital employed. For purposes of this calculation, average operating capital employed is considered to be all assets other than cash, deferred tax assets, hedging derivatives, goodwill and intangibles, less all liabilities other than debt, hedging derivatives and deferred tax liabilities.
