ENVISION HEALTHCARE REPORTS FIRST QUARTER NET REVENUE INCREASE OF 14.2% AND ADJUSTED EPS OF $0.20

Greenwood Village, Colo. (May 7, 2014) — Envision Healthcare Holdings, Inc. (NYSE: EVHC) (“EVHC” or “Company”) announces results for the first quarter ended March 31, 2014. All comparisons included in this release are for first quarter 2014 to first quarter 2013 unless otherwise noted.

Highlights:

·                  First quarter 2014 net revenue was $1.01 billion, an increase of 14.2%;

·                  First quarter 2014 Adjusted EBITDA was $110.0 million, an increase of 9.0%;

·                  First quarter 2014 Adjusted EPS was $0.20 and GAAP diluted EPS was $0.13; and

·                  The Company completed the acquisitions of Life Line Ambulance in Arizona and MedStat EMS in Mississippi with combined estimated annualized revenue of approximately $36 million.

William A. Sanger, Chief Executive Officer, said, “We are pleased with the start of 2014 and our industry leading organic growth. This trend is driven by new contracts at EmCare, Evolution Health and AMR. Our EmCare joint venture model continues to expand with the addition of both new system partners and new service offerings. We also recently signed a national agreement to provide Evolution Health services to one of the largest sub-acute care companies.

“We are encouraged by early indications of healthcare reform benefits as evidenced by a shift in self-pay to Medicaid in the expansion states.  We anticipate a continued reduction in self-pay mix throughout the remainder of the year as more uninsured migrate to Medicaid programs and the anticipated positive effects of exchange enrollment are realized.

“We believe the momentum in our businesses, combined with the impact of the ACA, has created a strong foundation for future growth.”

Results of Operations for the First Quarter 2014

For the first quarter of 2014, EVHC generated net revenue of $1.01 billion, an increase of 14.2%.

1

Adjusted EBITDA was $110.0 million, an increase of 9.0%. The increase was primarily attributable to the impact of increased revenue from net new contracts, same store contracts and acquisitions.

EVHC generated net income of $24.8 million, compared to net loss of $3.8 million. The increase in net income is primarily attributable to an increase in income from operations and the reduction of interest expense related to the redemption on December 30, 2013 of the 8.125% Senior Notes due 2019 (“2019 Notes”), the redemption on August 30, 2013 of the Senior PIK Toggle Notes due 2017 and the re-pricing of the Term Loan Facility and ABL Facility in February 2013.

Segment Results for the First Quarter 2014

EVHC operates two business segments: EmCare Holdings Inc. (“EmCare”), the Company’s facility-based and post-acute care physician services segment and American Medical Response, Inc. (“AMR”), the Company’s healthcare transportation services segment.

EmCare

EmCare generated net revenue of $644.6 million, an increase of $89.7 million, or 16.2%. Organic growth was 15.9%, attributable to an increase of $73.9 million, or 13.4%, from net new contracts, and an increase of $14.0 million, or 2.5%, from “same store” contracts. Same contract volumes were lower in the quarter by 1.4% primarily related to lower emergency department visits as a result of a mild flu season and weather-related impacts early in the quarter. Same contract revenue per encounter increased by 3.9% primarily due to higher acuity, an improvement in payor mix and Medicaid parity reimbursement. Revenue from acquisitions increased $1.8 million, or 0.3%.

Adjusted EBITDA was $71.4 million, an increase of $5.2 million, or 7.9%. The increase in Adjusted EBITDA was primarily driven by the net impact of revenue increases from net new contracts and same store revenue growth, offset by an increase of $6.7 million in start-up compensation costs. The number of new contract starts in the last two quarters was approximately 40% higher than the comparable period last year. Many of these new contracts had accelerated start dates, leading to higher compensation costs due to increased temporary staffing requirements. The quarter also included a $3.3 million reduction to minority interest due to an adjustment of profit sharing associated with the HCA joint venture, offset by an unfavorable prior period insurance adjustment of $2.0 million. Income from operations was $51.2 million, an increase of $3.3 million, or 7.0%.

American Medical Response (AMR)

AMR generated net revenue of $369.6 million, an increase of $36.3 million, or 10.9%. Organic growth was 5.9%, driven by a 5.3% increase related to net new contract wins and increased revenue of 0.6% in existing markets. Acquisitions contributed to 5.0% revenue growth.

Adjusted EBITDA was $38.6 million, an increase of $3.8 million, or 10.9%. The increase was attributable to the net impact of higher revenue increases in existing markets from new contract wins and acquisitions. The quarter included a reduction to general and administrative expenses of $1.9 million related to a property settlement offset by an unfavorable prior period insurance adjustment of $3.2 million. First quarter 2013 included a favorable prior period insurance adjustment of $1.7 million. Income from operations was $17.1 million, an increase of $2.0 million, or 13.6%.

Cash Flows for the First Quarter 2014

Cash provided by operating activities was $30.2 million, compared to $6.6 million. When excluding $14.8 million of income tax effect related to exercised stock options in conjunction with the secondary offering in 2014 and $24.5 million in non-recurring outflows in 2013, operating cash flows were $45.0 million compared to $31.1 million. The change was primarily driven by a decrease in cash interest payments offset by an increase in insurance payments which included payments of approximately $10 million for the previously disclosed malpractice settlements in the fourth quarter of 2013. Days Sales Outstanding (“DSO”) decreased one day from the fourth quarter of 2013. While AMR’s DSO decreased by one day, EmCare’s DSO remained unchanged primarily as a result of an increase in the number of new contract starts.

Net cash used in investing activities was $40.0 million, compared to $4.8 million. The increase in investing cash flow was primarily driven by acquisitions which were $35.8 million compared to $1.4 million.

Net cash used in financing activities was $4.0 million compared to net cash provided by financing activities of $20.4 million.  The quarter includes $14.4 million of payments for employee related taxes for stock options exercised in connection with the secondary offering. At March 31, 2014, there were no amounts outstanding under the ABL Facility.

Adjusted Free Cash Flow was $40.8 million, compared to $27.8 million. The difference was primarily attributable to aforementioned changes in cash paid for interest and insurance claims paid.

2014 Guidance

The Company previously announced 2014 Adjusted EPS guidance of $1.10 to $1.15, and Adjusted EBITDA guidance of $538 million to $545 million. At this time, the Company is not adjusting its guidance while it continues to evaluate the expected 2014 benefit from healthcare reform.

Non-GAAP Financial Measures Description and Reconciliation

This press release includes presentations of Adjusted EBITDA, which is defined as net income before equity in earnings of unconsolidated subsidiary, income taxes, other (expense) income, net, loss on early debt extinguishment, realized gains (losses) on investments, interest expense, equity-based compensation, related party management fees, restructuring charges and depreciation and amortization expense.

It also includes presentations of Adjusted Free Cash Flow, which is defined as cash flow from operations adjusted for cash used in non-acquisition related investing activities and certain out-of-period or non-recurring cash payments.

This press release also includes presentations of Adjusted EPS, which is defined as diluted earnings per share adjusted for expenses related to the Company’s secondary offering, amortization expense, equity-based compensation expense and restructuring charges, net of an estimated tax benefit.

These non-GAAP financial measures, Adjusted EBITDA, Adjusted Free Cash Flow, and Adjusted EPS are commonly used by management and investors as performance measures and liquidity indicators. The Company’s non-GAAP financial measures are not considered measures of financial performance under U.S. generally accepted accounting principles (GAAP), and the items excluded therefrom are significant components in understanding and assessing our financial performance. These non-GAAP financial measures should not be considered in isolation or as an alternative to GAAP measures such as net income, cash flows provided by or used in operating, investing or financing activities or other financial statement data presented in our consolidated financial statements as an indicator of financial performance or liquidity. Reconciliations of non-GAAP financial measures are provided in this press release.  Reconciliation for the forward-looking full-year 2014 Adjusted EBITDA and Adjusted EPS projections presented herein is not being provided due to the number of variables in the projected full-year 2014 Adjusted EBITDA and Adjusted EPS ranges and thus we do not currently have sufficient data to accurately estimate the individual adjustments for such a reconciliation. Since these non-GAAP financial measures are not measures determined in accordance with GAAP and are susceptible to varying calculations, these measures, as presented, may not be comparable to other similarly titled measures of other companies.
