2016 Outlook Updated

Greenwood Village, Colo. (November 1, 2016) — Envision Healthcare Holdings, Inc. (Envision or Company) (NYSE: EVHC) reports results from operations for the three months and nine months ended September 30, 2016.  All comparisons included in this release are for the 2016 periods to the comparable 2015 periods, unless otherwise noted.

Highlights:

·                  Net revenue of $1.64 billion, an increase of 19.8%;

·                  Net income of $25.9 million, an increase of 50.2%;

·                  Adjusted EBITDA of $180.7 million, an increase of 26.8%;

·                  GAAP diluted earnings per share (EPS) was $0.13, an increase of 44.4%; and

·                  Adjusted diluted EPS was $0.36, an increase of 20.0%.

“In spite of lower sector volume growth in the period, our third quarter reflects strong operating results at EmCare, including encouraging progress at Evolution Health, and performance improvement at AMR’s Rural Metro operations,” said William A. Sanger, chairman, president and chief executive officer of Envision.  “Rural Metro’s margins improved, driven by continued integration into AMR’s operations and technology platforms.  Our results at Evolution Health improved as we realized benefits from our participation in bundled payment models and medical cost savings from our contract with a Florida health plan.

“The strategic investments we have made at Envision to expand our scale and scope continue to provide unique opportunities for the company and our stakeholders.  We believe these investments will be further enhanced by the merger between Envision and AMSURG Corp., which is expected to be completed this year.”

Results of Operations for the Third Quarter of 2016

Envision generated net revenue of $1.64 billion, an increase of 19.8%, driven by contributions from acquisitions of 16.1%, and organic growth of 3.7%.  Net income was $25.9 million and Adjusted EBITDA was $180.7 million.   Envision earned $0.13 per diluted share on a GAAP basis and Adjusted diluted EPS for the quarter was $0.36.

Segment Results for the Third Quarter of 2016

Envision operates two business segments: EmCare Holdings (EmCare), the Company’s facility-based and post-acute care physician-led services segment and American Medical Response (AMR), the Company’s medical transportation services segment.

EmCare

EmCare’s net revenue for the third quarter of 2016 was $1.06 billion, an increase of 13.0% from the prior-year period.

Revenue from acquisitions completed during the past 12 months contributed growth of 9.0%. Organic revenue growth of 4.0% consisted of same-store contributions of 5.1% while revenue from net new contracts declined by 1.1%.  Revenue from net new contracts increased at Evolution Health and was offset by contract terminations, net of new contracts started at EmCare, during the last 12 months.

EmCare’s same-store revenue, when calculated from the comparable contract base for both periods, grew by 6.0% and included rate growth of 4.3%, driven by an increase in yield in all service lines, as well as same-contract growth at Evolution Health.  Same-store revenue growth from patient volume was 1.7% overall, with 1.1% from emergency department volume growth.

EmCare’s income from operations was $73.6 million, or 7.0% of revenue, which compares with $28.9 million, or 3.1% of revenue, and includes changes in restructuring and transaction costs in comparable periods. Adjusted EBITDA of $113.9 million was 10.8% of revenue, which compares with $86.4 million, or 9.2% of revenue.   EmCare’s results were impacted by Evolution Health, which generated revenue of $120.5 million in the third quarter and contributed Adjusted EBITDA of $1.7 million.

American Medical Response

AMR’s net revenue was $583.6 million and grew by 34.6% from the prior-year period.  Acquisition-related growth was 31.4%.  Growth from organic revenue sources was 3.2% and included net new contract growth of 2.2% and same-market growth of 1.0%.   When calculated on a comparable same-market basis, revenue growth was 1.2% and consisted of volume growth of 1.8%, offset by a 0.6% decline related to rate.  AMR’s same-market rate included contributions from improved commercial rates, offset by lower managed transportation revenue.

AMR’s income from operations was $9.7 million, or 1.7% of revenue, which compares with $31.1 million, or 7.2% of revenue.  The change in income from operations was driven primarily by higher transaction costs and depreciation and amortization expense.  Adjusted EBITDA was $66.8 million, or 11.4% of revenue, compared with $56.1 million, or 12.9% of revenue.

Envision Cash Flows for the Third Quarter of 2016

Envision generated cash flow from operations of $93.2 million.  This compares with cash flow from operations of $34.0 million.  Adjusted Free Cash Flow, a non-GAAP financial measure, was $47.7 million and was impacted primarily by expected higher capital expenditures, largely related to acquisition and new contract growth at AMR.  At the end of the quarter, Envision completed two acquisitions for net consideration of $66.1 million.  See “Non-GAAP Financial Measures Description and Reconciliation” below for a definition and reconciliation of Adjusted Free Cash Flow to Cash Flows from Operating Activities.

Results of Operations for the Nine Months Ended September 30, 2016

Envision’s net revenue was $4.88 billion, net income was $81.2 million, and Adjusted EBITDA was $504.2 million.   Envision generated cash flow from operations of $252.4 million, or $278.4 million when excluding certain non-recurring payments earlier in 2016, and Adjusted Free Cash Flow was $173.4 million.

Segment Results for the Nine Months ended September 30, 2016

Net revenue at EmCare was $3.12 billion, operating income was $198.9 million and Adjusted EBITDA was $305.0 million.

Net revenue at AMR was $1.76 billion, operating income was $60.7 million and Adjusted EBITDA was $199.2 million.

Merger Update

The previously announced merger between Envision and AMSURG remains on track for completion during the fourth quarter of 2016.  Both Envision and AMSURG mailed the definitive proxy statement/prospectus on October 21, 2016, and special meetings of shareholders of AMSURG and stockholders of Envision will be held on November 28, 2016, to vote on the merger proposals.

2016 Outlook

Envision Healthcare is updating its financial outlook for 2016.  Envision now expects to generate Adjusted EBITDA of $705 million to $715 million and Adjusted EPS of $1.39 to $1.42.   Envision’s outlook anticipates that lower volume growth at both EmCare and AMR will continue into the fourth quarter.

Envision is not providing a reconciliation of its forward-looking 2016 Adjusted EBITDA and Adjusted EPS because the Company is not able to accurately estimate the variables and individual adjustments for these items, including normal variability in income tax expense, equity compensation and transaction costs related to acquisition activities.  Envision believes that the variability of these items could have an impact on its GAAP financial results.
