Greenwood Village, Colo. (August 6, 2014) — Envision Healthcare Holdings, Inc. (NYSE: EVHC) (EVHC or Company) announces results for the second quarter ended June 30, 2014. All comparisons included in this release are for second quarter 2014 to second quarter 2013 unless otherwise noted.

Second Quarter 2014 Highlights:

·                  Net revenue was $1.08 billion, an increase of 19.6%;

·                  Adjusted EBITDA was $134.2 million, an increase of 26.6%;

William A. Sanger, president and chief executive officer, said, “Our integrated service offerings across our business segments continue to differentiate us in the market as evidenced by our strong revenue and EBITDA growth. Approximately 60% of our revenue growth was driven by net new contract wins, 25% from same store and 15% from acquisitions. EmCare’s net new contract wins continued at a record pace and contributed 15.4% to its overall revenue growth of 21.2%. AMR delivered its strongest performance in many years, with 16.7% revenue and 33.1% EBITDA growth.

“With respect to healthcare reform, we have seen a meaningful shift from self-pay into both Medicaid and healthcare exchange programs. We anticipate this positive trend to continue, resulting in additional volume and improved rates.

“Given the strength of our business, along with the positive benefits of healthcare reform, we are increasing our guidance for the full year.”

Results of Operations for the Second Quarter 2014

For the second quarter of 2014, EVHC generated net revenue of $1.08 billion, an increase of 19.6%.

1

Adjusted EBITDA was $134.2 million, an increase of 26.6%. This was primarily attributable to the impact of net new contract wins, improved volumes, a favorable shift in payor mix, effective expense control and acquisitions.

EVHC generated a net loss of $2.0 million, compared to net income of $9.6 million. The reduction in net income is primarily due to a $66.4 million pre-tax charge related to the early debt extinguishment of the 8.125% Senior Notes due 2019 (2019 Notes) in June of 2014, offset by the decrease in interest expense from debt retirements in 2013.

Segment Results for the Second 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 $690.0 million, an increase of 21.2%, or $120.9 million. Organic growth was 20.3%, driven by an increase of 15.4% from net new contracts, and an increase of 4.9% from same store contracts.  Acquisition growth was 0.9%.

On a same store basis, volumes were higher in the quarter by 5.3%, partially driven by additional volumes in both Medicaid expansion and non-expansion states. Same contract revenue per encounter increased by 0.2%. This was primarily driven by emergency department volume increases of 4.2% and emergency department rate increases of 2.9%. Same store revenue from other service lines increased 1.2%.

Adjusted EBITDA was $87.1 million, an increase of 23.4%, or $16.5 million. The increase in Adjusted EBITDA was primarily driven by revenue increases from net new contract wins and same store revenue growth. Income from operations was $68.8 million, an increase of 29.4%, or $15.6 million.

American Medical Response

AMR generated net revenue of $385.3 million, an increase of 16.7%, or $55.2 million. Organic growth increased 9.6%, driven by 5.0% related to net new contract wins and 4.6% in existing markets. The 4.6% in existing markets included a 3.6% volume increase, primarily driven by additional volumes in both Medicaid expansion and non-expansion state, and a 1.0% revenue increase per weighted transport. Acquisitions contributed 7.1% to revenue growth.

Adjusted EBITDA was $47.1 million, an increase of 33.1%, or $11.7 million. The increase was attributable to revenue increases and operating efficiencies as a result of cost improvement initiatives. Income from operations was $24.3 million, an increase of 94.0%, or $11.8 million.

Cash Flows for the Second Quarter 2014

Cash provided by operating activities was $63.7 million, compared to cash used in operating activities of $12.7 million. This improvement was driven by an increase in net income and cash collections and a decrease in cash interest payments in 2014 and non-recurring cash outflows that occurred in 2013. EmCare Days Sales Outstanding (DSO) decreased by three days in the quarter and AMR DSO remained unchanged.

Net cash used in investing activities was $184.6 million, compared to $23.0 million. The increase in cash used for investing was primarily driven by acquisitions in the quarter of $163.5 million.

2

Net cash provided by financing activities was $92.5 million, compared to net cash used in financing activities of $7.4 million. The net impact in the quarter was primarily due to the issuance of $750 million in 5.125% Senior Notes due 2022 and the redemption of the 2019 Notes (Bond Refinancing). At June 30, 2014, there were no amounts outstanding under the ABL Facility.

Adjusted Free Cash Flow was $43.5 million, compared to cash outflow of $18.8 million.

Results of Operations for the Six Months ended June 30, 2014

EVHC net revenue was $2.09 billion, an increase of 16.9%.

Adjusted EBITDA was $244.2 million, an increase of 18.0%. This increase was primarily attributable to the impact of increased revenue from net new contracts and existing contracts, effective expense controls, healthcare reform and acquisitions.

EVHC generated net income of $22.8 million, compared to $5.8 million. The increase in net income was primarily attributable to an increase in income from operations and the net impact of debt retirements in 2014 and 2013.

EmCare’s net revenue was $1.33 billion, an increase of 18.7%. Adjusted EBITDA was $158.5 million, an increase of 15.9%. Income from operations was $120.1 million, an increase of 18.8%.

Cash Flows for the Six Months Ended June 30, 2014

DSO decreased two days from December 31, 2013, with EmCare’s DSO decreasing by three days and AMR’s DSO decreasing by one day.

Net cash used in investing activities was $224.6 million, compared to $27.7 million. The increase in cash used for investing was primarily driven by acquisitions which were $199.3 million, compared to $1.4 million in 2013.

Net cash provided by financing activities was $88.5 million, compared to $13.0 million.  The net impact was primarily due to the Bond Refinancing.

Non-GAAP Financial Measures Description and Reconciliation

This press release includes presentations of Adjusted EBITDA, Adjusted Free Cash Flow and Adjusted EPS, which are not financial measures calculated and presented in accordance with generally accepted accounting principles in the United States of America (GAAP).  Adjusted EBITDA is defined as net income (loss) before equity in earnings of unconsolidated subsidiary, income tax benefit (expense), loss on early debt extinguishment, other income (expense), net, realized gains (losses) on investments, interest expense, net, equity-based compensation expense, related party management fees, restructuring charges, and depreciation and amortization expense.  Adjusted Free Cash Flow 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.  Adjusted EPS is defined as diluted earnings per share adjusted for expenses related to the Company’s secondary offering, amortization expense, equity-based compensation expense, restructuring charges and loss on early debt extinguishment, net of an estimated tax benefit.

These non-GAAP financial measures are commonly used by management and investors as performance measures and liquidity indicators. However, the items excluded from these non-GAAP financial measures are significant components in understanding and assessing the Company’s financial performance, and as a result, these 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 the Company’s consolidated financial statements as an indicator of financial performance or liquidity. 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.  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 the Company does not currently have sufficient data to accurately estimate the individual adjustments for such a reconciliation.
