EVHC News- For Immediate Release

ENVISION HEALTHCARE REPORTS 3RD QUARTER ADJUSTED EBITDA
INCREASE OF 17.6% AND ADJUSTED EPS OF $0.13

Greenwood Village, Colorado (November 13, 2013) — Envision Healthcare Holdings, Inc. (NYSE: EVHC) (EVHC or the Company) today announces results for the third quarter ended September 30, 2013.  All changes included in this release compare third quarter 2013 to third quarter 2012 unless otherwise noted.

Highlights:

·                  Third quarter 2013 net revenue was $955.9 million, an increase of 16.5%;

·                  Third quarter 2013 Adjusted EBITDA was $121.7 million, an increase of 17.6%; and

·                  Third quarter 2013 diluted EPS adjusted for expenses incurred in connection with the initial public offering (Adjusted EPS) was $0.13; and GAAP diluted EPS was ($0.05).

William A. Sanger, Chief Executive Officer, said, “During our first quarter as a public company we demonstrated exceptional revenue and Adjusted EBITDA growth. Customer demand for our differentiated services and the implementation of our market-centric strategies drove an increased level of contract starts and organic growth.  Furthermore, our initial public offering provides us with additional sources of liquidity to capitalize on market acquisitions and development opportunities.”

Results of Operations for the Third Quarter 2013

For the quarter ended September 30, 2013, EVHC generated net revenue of $955.9 million, an increase of 16.5% compared to the same period last year.

Adjusted EBITDA was $121.7 million, an increase of 17.6% compared to the same quarter last year. This increase is attributable primarily to the impact of increased volume from net new contracts, increased revenue from “same store” contracts (contracts in existence for the entirety of both periods) and acquisitions, and a decrease in expenses as a percentage of revenue.

EVHC generated a net loss of $7.7 million in the third quarter of 2013 compared to net income of $15.2 million in the third quarter of 2012.  The decrease in net income is attributable primarily to the impact of costs incurred in connection with the Company’s initial public offering (IPO-Related Costs), including a $20.0 million payment to terminate the consulting agreement with Clayton, Dubilier & Rice, LLC (CD&R) and $29.5 million in costs related to the redemption of our Senior PIK Toggle Notes due 2017 (PIK Notes).

Segment Results

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

For the quarter ended September 30, 2013, EmCare generated net revenue of $605.1 million, an increase of 24.5%, 16.4% of which was from organic growth.  The increase in revenue was attributable primarily to the addition of $64.0 million, or 13.1% from net new contracts started since September 30, 2012, and revenue increases at “same store” contracts.  Revenue at “same store” contracts grew 3.8% or $16.0 million.  Revenue from acquisitions increased $39.2 million during the quarter ended September 30, 2013 and included $27.2 million from our post-acute care services acquisitions.

Adjusted EBITDA was $82.0 million for the quarter compared to $68.8 million last year, an increase of 19.3%.  The increase in Adjusted EBITDA was driven primarily by the net impact of revenue increases from net new contracts and acquisitions and a decrease in operating and general and administrative expense as a percentage of net revenue. These were offset by higher compensation costs driven by start-up costs associated with our new contract starts.  Income from operations was $55.7 million, an increase of 2.7% over the same period in 2012 due primarily to allocated IPO-Related Costs.

American Medical Response (AMR)

For the quarter ended September 30, 2013, AMR generated net revenue of $350.8 million, an increase of $15.9 million, or 4.8%, compared to the same quarter last year.  The increase in net revenue was from an increase in existing markets and from new 911 contract wins, offset by 2012 FEMA deployment revenue and exited markets. Existing market revenue increased $9.0 million, or 2.8%, in the quarter.

Adjusted EBITDA was $39.6 million, an increase of 14.2% compared to the same quarter last year.  The increase in Adjusted EBITDA is attributable to revenue increases and to lower expenses as a percentage of revenue related to the implementation of our deployment and other efficiency initiatives.  Insurance expense for the quarter ended September 30, 2013 included an unfavorable prior period insurance adjustment of $1.7 million compared to an unfavorable prior period adjustment of $0.1 million in the same period last year.  Income from operations was $7.8 million, a decrease of 46.0% compared to the same quarter in 2012 due primarily to allocated IPO-Related Costs.

Cash Flows

Cash provided by operating activities was $51.7 million in the third quarter of 2013 excluding operating cash outflows of $20 million for IPO-Related Costs, compared to $106.1 million for the same quarter last year.  The difference of $54.4 million relates to an increase in net income (excluding IPO-Related Costs), offset by an income tax refund of $43.0 million received in the third quarter of 2012 and an increase in accounts receivable at September 30, 2013.  Days Sales Outstanding (DSO) increased by five days from the second quarter of 2013. While AMR’s DSO remained unchanged, EmCare’s DSO increased 6 days primarily as a result of two factors. First, as we discussed in our IPO roadshow, provider enrollments were previously delayed by CMS due to a requested change in our enrollment processes.  We made the requested modifications and in late September, CMS released a majority of the enrollments.  We expect collections on these receivables to reduce our DSO in the fourth quarter.  Second, we had a significant number of recent contract starts. New contracts typically

2

experience an increase in accounts receivable and DSO for 6 — 9 months before we return to a normalized collection pattern.

Net cash used in investing activities was $42.3 million for the quarter ended September 30, 2013, compared to $47.6 million for the same period in 2012. Insurance collateral funding decreased $21.1 million due to timing differences in insurance funding.  Net capital expenditures increased $5.7 million due primarily to new AMR 911 contract wins.  Acquisitions were $25.9 million in the third quarter of 2013 compared to $19.3 million in the same period last year.

For the quarter ended September 30, 2013, net cash provided by financing activities was $549.3 million compared to net cash used in financing activities of $54.3 million for the third quarter of 2012.  During the quarter, we received proceeds from our initial public offering of $1.1 billion offset by related issuance costs paid of $62.0 million.  We paid $462.4 million during the quarter to redeem the PIK Notes, including a $12.4 million premium payment.  In addition, we repaid the outstanding balance on our revolving credit facility of $27.5 million.  At September 30, 2013, there were no amounts outstanding under our revolving credit facility.

Adjusted Free Cash Flow was $35.4 million in the third quarter of 2013 compared to $77.7 million in the third quarter of 2012.  The difference is attributable primarily to aforementioned changes in accounts receivable at EmCare and the income tax refund received during the third quarter of 2012.

Results of Operations for the Nine Months Ended September 30, 2013

EVHC net revenue was $2.74 billion for the nine months ended September 30, 2013, an increase of 13.0% compared to the same period last year.

Adjusted EBITDA was $328.5 million, an increase of 12.8% compared to the same period last year. This increase is attributable primarily to the impact of increased volume from net new contracts, increased revenue from existing contracts and acquisitions.

EVHC generated net loss of $1.9 million for the nine months ended September 30, 2013, compared to net income of $28.8 million, for the same period last year, a decrease of $30.7 million.   The decrease in net income is attributable primarily to the IPO-Related Costs indicated above.

Segment Results

For the nine months ended September 30, 2013, EmCare’s net revenue was $1.73 billion, an increase of 23.2% compared to the same period last year.  Adjusted EBITDA was $218.8 million, an increase of 15.6% compared to the same period last year.  Income from operations was $156.8 million, an increase of 8.5% compared to the same period in 2012.

For the nine months ended September 30, 2013, AMR’s net revenue was $1.01 billion, a decrease of 1.0% compared to the same period last year related primarily to market exits during 2012.  Adjusted EBITDA was $109.8 million, an increase of 7.6% compared to the same period last year.  Income from operations was $35.3 million, a decrease of 4.2% compared to the same period in 2012.

Cash Flows

Cash provided by operating activities was $83.8 million for the nine months ended September 30, 2013, excluding $58.2 million in non-recurring outflows, compared to $169.2 million for the same period last

3

year.  The non-recurring operating outflows included the IPO-Related Costs outflows of $20 million, a $13.7 million operating cash flow payment to settle a prior shareholder lawsuit, and $24.5 million of payments related to a 2012 AMR contract termination and our 2012 FEMA deployment for hurricane Sandy.  The difference of $85.4 million primarily relates to an income tax refund of $43.0 million received in the third quarter of 2012 and an increase in accounts receivable.  While AMR’s DSO decreased 4 days during the nine months ended September 30, 2013, EmCare’s DSO increased 12 days primarily as a result of provider enrollments previously delayed by CMS and a significant number of new contract starts as previously noted.

Net cash used in investing activities was $70.0 million for the nine months ended September 30, 2013, compared to net cash provided by investing activities of $33.4 million for the same period in 2012. The decrease is due primarily to a return of insurance collateral of approximately $100 million during the nine months ended September 30, 2012.

For the nine months ended September 30, 2013, net cash provided by financing activities was $562.3 million compared to net cash used in financing activities of $208.3 million for the same period in 2012. The increase in cash provided by financing activities is related primarily to proceeds from our initial public offering offset by redemption of our PIK Notes and payment to settle a prior shareholder lawsuit.

Adjusted Free Cash Flow was $41.2 million in the nine months ended September 30, 2013 compared to $223.2 million for the same period in 2012. The difference is attributable primarily to the aforementioned return of insurance collateral, income tax refund received in 2012, and the increase in EmCare accounts receivable.

A description of the non-GAAP measures, Adjusted EPS, Adjusted EBITDA and Adjusted Free Cash Flow, and a reconciliation of non-GAAP to GAAP financial measures are included in this press release.

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 2013 Adjusted EBITDA projection presented herein is not being provided due to the number of variables in the projected full-year 2013 Adjusted EBITDA range and thus we do not currently have sufficient data to accurately estimate the individual adjustments for such a reconcilition.
