SCOTTSDALE, Ariz. (May 10, 2010) – Rural/Metro Corporation (NASDAQ: RURL), a leading provider of ambulance and private fire protection services, today announced strong financial results for its fiscal 2010 third quarter ended March 31, 2010.

“We are pleased to announce solid growth in the third fiscal quarter, supported by reduced uncompensated care, rate increases, growth in transport volume and strong cash flows,” said Conrad A. Conrad, interim President and Chief Executive Officer. “Following strong year-to-date performance, we have raised our fiscal 2010 guidance for Adjusted EBITDA from continuing operations to a range of $67.0 million to $69.0 million from the previous range of $63.0 million to $65.0 million.”

Results of Operations for the Fiscal 2010 Third Quarter Ended March 31, 2010

For the quarter ended March 31, 2010, the Company generated net revenue of $133.1 million, an increase of 7.5%, or $9.2 million, compared to $123.9 million for the same period last year. The increase was attributable primarily to same-service-area growth, which included reductions in uncompensated care and rate increases, as well as a 4.5% increase in total transport volume in the quarter.

Payroll and employee benefits expense for the third fiscal quarter was $80.0 million, or 60.1% of net revenue, compared to $76.0 million, or 61.3% of net revenue, in the same period of the prior year. The year-over-year increase in payroll dollars incurred was driven primarily by additional labor hours deployed in response to the increase in ambulance transport volume and higher expenses for employee health insurance.

Other operating expenses for the third fiscal quarter were $31.4 million, or 23.6% of net revenue, compared to $28.0 million, or 22.6% of net revenue for the same prior-year period. The year-over-year increase is attributable primarily to increases in professional fees and vehicle and equipment expense related to growth in transport volume and fuel prices.

General and auto liability insurance expense for the third fiscal quarter was $3.4 million, or a decrease of $1.5 million, when compared to $4.9 million for the same period of the prior year. There were no actuarial adjustments recorded in the third quarter.

During the third quarter, the Company redeemed $4.0 million of 9.875% Senior Subordinated Notes (the “Notes”) that remained outstanding following the Company’s November 2009 tender offer. The loss on debt extinguishment related to those remaining Notes was $0.3 million.

Including the $0.3 million loss on debt extinguishment, third-quarter net income attributable to Rural/Metro was $3.8 million, or diluted EPS of $0.15, compared to net income of $1.0 million and EPS of $0.04 for the third quarter of the prior year. Excluding the $0.3 million loss on debt extinguishment and its related tax effect, quarterly net income would have been $4.5 million, or diluted EPS of $0.18.

Adjusted EBITDA from continuing operations for the third quarter increased 22.5% to $17.9 million compared to $14.7 million for the same period in fiscal 2009. Adjusted EBITDA from continuing operations excludes the effect of the quarterly loss on debt extinguishment of $0.3 million as well as share-based compensation expense of $87,000.

Results of Operations for the Nine Months Ended March 31, 2010

For the nine months ended March 31, 2010, the Company generated net revenue of $396.9 million, an increase of 8.8% compared to $364.9 million for the same period last year. The increase was attributable primarily to same-service-area growth, which included reductions in uncompensated care and rate increases, as well as a 3.6% increase in total transport volume.

Payroll and employee benefits expense for the nine-month period was $241.8 million, or 60.9% of net revenue, compared to $225.1 million, or 61.7% of net revenue for the same period of the prior year. The year-over-year increase in payroll dollars incurred was driven primarily by additional labor hours driven as a result of increased transport volume, and higher expenses related to employee health and workers’ compensation insurance.

Other operating expenses for the nine-month period were $90.1 million, or 22.7% of net revenue, compared to $84.6 million, or 23.2% of net revenue for the same period of the prior year. The year-over-year difference in actual dollars spent was attributable primarily to increases in operating equipment and supplies related to higher transport volume, as well as additional professional fees. These increases were offset by a year-to-date decrease in fuel expense.

General and auto liability insurance expense for the first nine months of fiscal 2010 was $12.0 million, compared to $10.6 million for the same prior-year period. The year-over-year variance was driven primarily by a $1.1 million increase in current-year claims costs and a $0.3 million net increase in actuarial adjustments.

2

Net income attributable to Rural/Metro for the first nine months of fiscal 2010 including the $14.2 million loss on debt extinguishment, was $1.9 million, or diluted EPS of $0.08, compared to net income of $2.8 million and diluted EPS of $0.11 in the first nine months of fiscal 2009. Excluding the $14.2 million loss on debt extinguishment, net income for the nine-month period would have been $10.6 million, or diluted EPS of $0.42.

Cash flows for the period remained strong, with year-to-date net cash provided by operating activities of $38.3 million, compared to $37.3 million for the same prior-year period.

Adjusted EBITDA from continuing operations for the first nine months of fiscal 2010 increased 19.3% to $52.3 million, compared to $43.8 million for the same period in fiscal 2009. Adjusted EBITDA from continuing operations excludes the effect of the year-to-date loss on debt extinguishment of $14.2 million as well as share-based compensation expense of $0.4 million.

Adjusted EBITDA from continuing operations, net income and diluted EPS attributable to Rural/Metro, in each instance excluding the loss on debt extinguishment are key indicators management uses to evaluate operating performance. While Adjusted EBITDA from continuing operations, net income and diluted EPS attributable to Rural/Metro, in each instance excluding the loss on debt extinguishment are not intended to replace presentations included in the Company’s consolidated financial statements under generally accepted accounting principles (GAAP) and should not be considered an alternative to operating performance or an alternative to cash flow as a measure of liquidity, the Company believes these measures are useful to investors in assessing its ability to meet future debt service, capital expenditure and working capital requirements. This calculation may differ in the method of calculation from similarly titled measures used by other companies. A reconciliation of Adjusted EBITDA to income/(loss) from continuing operations and discontinued operations for the three and nine months ended March 31, 2010 and 2009, as well as a reconciliation of net income and diluted EPS attributable to Rural/Metro excluding the loss on debt extinguishment to net loss attributable to Rural/Metro and diluted earnings per share for the three and nine months ended March 31, 2010 and 2009, are included with this press release and the related current report on Form 8-K.

Quarterly Operating Statistics

The table below provides results for medical transports, Average Patient Charge (APC), and Days Sales Outstanding (DSO) during each of the five most recent quarters:

• The quarterly increase in transport volume when compared to the same prior-year period was driven primarily by growth in non-emergency transports.

• APC improvement of $20 per transport when compared to the fiscal 2009 third quarter was primarily due to continued reductions in uncompensated care and rate increases. Uncompensated care as a percentage of gross revenue decreased to 12.9%, as compared to 13.7% for the third quarter of fiscal 2009 and 13.4% for the second quarter of fiscal 2010. APC represents average cash collected per ambulance transport during the period.

• DSO improved by 11 days when compared to the third quarter of fiscal 2009 and two days when compared to the second quarter of fiscal 2010. This improvement was related primarily to the Company’s ongoing national implementation of its electronic patient care record system, as well as overall billing and collections improvements.
