The Mergers and the Merger Agreement

A copy of the Merger Agreement is attached as Annex A to this joint proxy statement/prospectus. Envision and AmSurg encourage you to read the entire Merger Agreement carefully because it is the principal document governing the Mergers. For more information on the Merger Agreement, see “Merger Agreement” beginning on page 142.

Effects of the Mergers (See page 65)

Subject to the terms and conditions of the Merger Agreement:

As a result, among other things, (1) Newco will be renamed “Envision Healthcare Corporation,” (2) existing AmSurg common shareholders will receive shares of Newco common stock, (3) existing AmSurg preferred shareholders will receive shares of Newco Series A-1 Preferred Stock with substantially the same terms as the AmSurg Preferred Stock and (4) existing Envision stockholders will receive shares of Newco common stock. Prior to the completion of Merger 1, Envision Healthcare Corporation (“EHC”), a wholly-owned indirect subsidiary of Envision, will merge with and into Envision Healthcare Intermediate Corporation (“EHIC”), a wholly-owned direct subsidiary of Envision, with EHIC as the surviving corporation of such merger, and, following such merger, EHIC will merge with and into Envision, with Envision as the surviving corporation of such merger.

The organization of Envision, AmSurg and Newco before and after the Mergers is set forth below:

Merger 1 Conversion and Merger 2 Consideration (See page 143)

Merger 1 Conversion . Subject to the terms and conditions set forth in the Merger Agreement, upon the effective time of Merger 1, each share of AmSurg common stock will automatically be converted into one share of Newco common stock and each share of AmSurg Preferred Stock will automatically be converted into one share of Newco Series A-1 Preferred Stock. Holders of AmSurg common stock will have the right, but not the obligation, to exchange certificates representing their AmSurg shares for certificates representing the Newco shares into which such AmSurg shares will automatically convert upon the effective time of Merger 1.

Merger 2 Consideration . Subject to the terms and conditions set forth in the Merger Agreement, upon the effective time of Merger 2, each share of Envision common stock will be converted into the right to receive 0.334 shares of Newco common stock, with cash paid in lieu of any fractional shares.

The Merger Agreement does not contain any provision that would adjust the number of shares of Newco stock issuable to Envision stockholders or AmSurg shareholders based on fluctuations in the market value of Envision’s common stock or AmSurg’s common stock or preferred stock. As a result, the implied value of the Newco stock issuable to Envision stockholders and AmSurg shareholders in the Mergers will fluctuate prior to the completion of the Mergers.

The number of Newco shares to be issued to Envision stockholders and AmSurg shareholders, respectively, in the Mergers, will result in approximately 53% of the issued and outstanding shares of Newco common stock

(on a fully diluted basis) immediately following the completion of the Mergers being owned by former Envision stockholders and approximately 47% of the issued and outstanding shares of Newco common stock (on a fully diluted basis) immediately following the completion of the Mergers being owned by former AmSurg shareholders based on the number of shares of Envision common stock, AmSurg common stock and AmSurg Preferred Stock outstanding on June 7, 2016.

On June 7, 2016, the last trading day prior to public reports regarding the proposed Mergers, the closing price on the NYSE was $25.54 per share of Envision common stock and the closing price on NASDAQ was $76.36 per share of AmSurg common stock and $142.25 per share of AmSurg Preferred Stock. On October 19, 2016, the latest practicable date before the date of this joint proxy statement/prospectus, the closing price on the NYSE was $22.10 per share of Envision common stock and the closing price on NASDAQ was $66.46 per share of AmSurg common stock. We urge you to obtain current market quotations before voting your shares.

It is a condition to the obligation of Envision to effect the Mergers that Envision receive a written opinion from Debevoise & Plimpton LLP, counsel to Envision, dated the Closing Date, to the effect that for U.S. federal income tax purposes the Mergers will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

It is a condition to the obligation of AmSurg to effect the Mergers that AmSurg receive a written opinion from Bass Berry & Sims PLC, counsel to AmSurg, dated the Closing Date, to the effect that for U.S. federal income tax purposes each of Merger 1 and Merger 2 will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

Regulatory Clearances Required for the Mergers

AmSurg and Envision have each agreed to use their reasonable best efforts to obtain all necessary waivers, consents, approvals, orders and authorizations from governmental entities with respect to the Merger Agreement required under applicable law.

The premerger waiting period expired at 11:59 p.m. on September 1, 2016. Although AmSurg and Envision believe that the transactions do not raise substantial regulatory concerns and that all remaining regulatory approvals will be obtained on a timely basis, AmSurg and Envision cannot be certain when, if or under what conditions these approvals will be obtained.

Subject to the terms and conditions of the Merger Agreement, AmSurg will merge with and into Newco, with Newco continuing as the surviving corporation, immediately after which Envision will merge with and into Newco, with Newco continuing as the surviving corporation. Upon the closing of Merger 2, the name of Newco will be changed to “Envision Healthcare Corporation.”

Upon the closing of Merger 1, each issued and outstanding share of AmSurg common stock, no par value, will automatically convert into one share of common stock, par value $0.01 per share, of Newco, and each issued

and outstanding share of AmSurg Preferred Stock will automatically convert into one share of Newco Series A-1 Preferred Stock. Upon the closing of Merger 2, each issued and outstanding share of Envision common stock, par value $0.01 per share, will automatically convert into the right to receive 0.334 shares of Newco common stock. Upon the closing of Merger 2, Envision stockholders will own approximately 53% and AmSurg shareholders will own approximately 47% of Newco (on a fully diluted basis).

Shares of Newco common stock to be issued in Merger 1 and Merger 2 are expected to be listed on the NYSE under the symbol “EVHC” and shares of Newco Series A-1 Preferred Stock to be issued in Merger 1 are expected to be listed on the NYSE under the symbol “EVHCPR.” No fractional shares of Newco common stock will be issued in the Mergers, and holders of shares of Envision common stock will receive cash in lieu of any such fractional shares. AmSurg stock options and other equity awards will generally, upon completion of Merger 1, be converted into an equal number of stock options and equity awards of Newco common stock. Envision stock options and other equity awards will generally, upon completion of Merger 2, be converted into stock options and equity awards with respect to Newco common stock based on the Exchange Ratio.

The Merger Agreement provides that, upon the closing of Merger 2, the Newco Board will be comprised of 14 directors, consisting of seven of AmSurg’s current directors and seven of Envision’s current directors. The composition of the Newco Board may not be altered until the first anniversary of the completion of the Mergers and the size of the Newco Board may not be increased or decreased until the third anniversary of the completion of the Mergers, unless approved, in each case, by at least 75% of the Newco Board.

Upon completion of the Mergers, Mr. Sanger, the current Chairman, President and Chief Executive Officer of Envision, will serve as Executive Chairman of Newco until the first anniversary of the completion of the Mergers and thereafter as non-Executive Chairman of the Newco Board until the third anniversary of the completion of the Mergers. Mr. Holden, currently a director and President and Chief Executive Officer of AmSurg, will serve as a director and as the Chief Executive Officer and President of Newco. Pursuant to the Merger Agreement and the Newco Bylaws, until the third anniversary of the completion of the Mergers, the affirmative vote of at least 75% of the Newco Board will be required (x) to remove or terminate Mr. Holden as the Chief Executive Officer and President of Newco or to determine not to have the Chief Executive Officer and President of Newco be a director, (y) to remove or terminate Mr. Sanger as Executive Chairman of the Newco Board before the first anniversary of the completion of the Mergers or (z) to remove Mr. Sanger as non-Executive Chairman of the Newco Board or to determine not to re-nominate Mr. Sanger as a director of Newco.

The Mergers are intended to qualify as a tax-free reorganization under the Code, so that none of Envision, AmSurg, Newco or any of the AmSurg shareholders or Envision stockholders generally will recognize any gain or loss on the issuance or receipt of Newco common stock in the Mergers, except that Envision stockholders generally may recognize gain or loss with respect to cash received in lieu of fractional shares of Newco common stock.

Neither AmSurg nor Envision is permitted to solicit, initiate or knowingly encourage or induce any competing proposals from third parties or to engage in discussions or negotiations with third parties regarding any competing proposals. Notwithstanding this limitation, prior to a party’s stockholders or shareholders, as applicable, approving the transactions, including the Mergers, such party may under certain circumstances provide information to and participate in discussions or negotiations with third parties with respect to an unsolicited competing proposal that its board of directors has determined in good faith, after consultation with its outside financial advisors and outside legal counsel, is or could reasonably be expected to lead to a superior proposal. Each party’s board of directors may change its recommendation to its stockholders or shareholders, as applicable, (subject to the other party’s right to terminate the Merger Agreement following such change in recommendation) in response to a Superior Proposal or an Intervening Event (as such terms are defined in the Merger Agreement) if such party’s board of directors determines in good faith, after consultation with its outside legal counsel, that the failure to take such action would be inconsistent with the exercise of the directors’ fiduciary duties under applicable law.

The Merger Agreement contains certain termination rights for both AmSurg and Envision. Upon termination of the Merger Agreement, under certain specified circumstances, (i) AmSurg may be required to pay a termination fee of $180 million to Envision, (ii) Envision may be required to pay a termination fee of $180 million to AmSurg and (iii) a party may be required to reimburse the other party for expenses of up to $15 million.

For a more complete discussion of the key terms of the Merger Agreement, see “Merger Agreement” beginning on page 142.

Comparison of Stockholders’ Rights

Upon completion of the Mergers, AmSurg shareholders and Envision stockholders will become stockholders of Newco and their rights will be governed by Delaware law and the governing corporate documents of Newco in effect at the effective time of the Mergers. AmSurg shareholders and Envision stockholders will have, in some respects, different rights once they become Newco stockholders due to differences between the governing corporate documents of each of the entities and, in the case of AmSurg shareholders, differences between Delaware law and Tennessee law. These differences are described in detail in the section entitled “Comparison of Rights of AmSurg Shareholders, Envision Stockholders and Newco Stockholders” beginning on page 191.

Listing of Newco Common Stock; Delisting and Deregistration of Envision and AmSurg Common Stock

AmSurg and Envision have agreed pursuant to the Merger Agreement to use their reasonable best efforts to cause (i) the shares of Newco common stock to be issued to AmSurg shareholders and Envision stockholders in connection with the Mergers and (ii) the shares of Newco Series A-1 Preferred Stock to be issued to holders of AmSurg Preferred Stock in connection with the Mergers to be approved for listing on the NYSE, subject to official notice of issuance. When the Mergers are completed, each of the AmSurg common stock and AmSurg Preferred Stock currently listed on NASDAQ, will cease to be quoted on NASDAQ and will subsequently be deregistered under the Exchange Act. Likewise, when the Mergers are completed, the Envision common stock currently listed on the NYSE will cease to be quoted on the NYSE and will subsequently be deregistered under the Exchange Act.

Financing

Newco expects to borrow on or before the effective date of the Mergers the funds necessary to consummate the Mergers and to refinance and repay certain existing indebtedness of EHC and AmSurg. On April 26, 2016, Envision and AmSurg first distributed a draft term sheet for the financing required to complete the Mergers to each of JPMorgan Chase Bank, N.A. (“JPM”) and Barclays Bank PLC (“Barclays Bank”), and instructed each of JPM and Barclays Bank to submit a separate term sheet with its proposed terms for the financing and not to discuss such proposed terms with each other. During April and May 2016, management of Envision and AmSurg jointly negotiated the terms of the financing with each of JPM and Barclays Bank. Throughout this period, neither JPM nor Barclays was aware of the other bank’s proposals and neither was guaranteed to receive any role or title in connection with the financing.

Following those negotiations, Envision and AmSurg determined to engage both JPM and Barclays Bank to provide the financing, and on June 15, 2016, EHC, a wholly-owned indirect subsidiary of Envision, and AmSurg signed a commitment letter (the “Commitment Letter”) with JPM and Barclays Bank PLC (JPM and Barclays Bank are collectively referred to herein as the “Commitment Parties”), pursuant to which the Commitment Parties committed to provide EHC and AmSurg with (i) a term loan facility in an aggregate principal amount of up to $5.3 billion (the “Term Loan Facility”) and (ii) a senior secured asset-based revolving credit facility in an aggregate principal amount of up to $1.0 billion in connection with the Mergers (the “ABL Facility” and, together with the Term Loan Facility, the “Credit Facilities”). Newco expects the terms of the Credit Facilities to

be substantially consistent with the terms of the facilities under its existing Credit Agreement, dated as of May 25, 2011, among EHC, certain of its subsidiaries, its borrowers, Deutsche Bank AG New York Branch, as administrative agent and collateral agent, and the lenders party thereto (as previously amended by Amendment No. 1, dated as of February 7, 2013, Amendment No. 2, dated as of October 28, 2015, Amendment No. 3, dated as of November 12, 2015, Amendment No. 4, dated as of November 12, 2015, Amendment No. 5, dated as of January 26, 2016, and Amendment No. 6, dated as of July 25, 2016, the “Existing Term Loan Credit Agreement”) and the its existing Credit Agreement, dated as of May 25, 2011, among EHC and certain of its subsidiaries, as borrowers, Deutsche Bank AG New York Branch, as administrative agent and collateral agent, and the lenders party thereto (as amended by Amendment No. 1, dated as of February 27, 2013, and Amendment No. 2, dated as of February 6, 2015, and as may be further amended, waived, supplemented or otherwise modified from time to time, the “Existing ABL Credit Agreement”), other than certain changes expressly contemplated by the Commitment Letter. For a more complete description of the expected terms of the Credit Facilities, see “The Mergers—Description of Credit Facilities” beginning on page 138.

On July 25, 2016, EHC received a change of control waiver, pursuant to which the definition of “Change of Control” was amended such that the Mergers will not constitute a “Change of Control” (the “Term Loan Change of Control Waiver”), under the Existing Term Loan Credit Agreement. On August 17, 2016, AmSurg received a change of control waiver, pursuant to which the definition of “Change of Control” was amended such that the Mergers will not constitute a “Change of Control” (the “Indenture Change of Control Waiver”), under that certain Indenture, dated as of July 16, 2014, among AmSurg, the guarantors party thereto and U.S. Bank National Association, as trustee (as amended by the First Supplemental Indenture, dated as of July 16, 2014, the “AmSurg 2022 Indenture”), which governs AmSurg’s 5.625% senior notes due 2022 (the “AmSurg 2022 Notes”).

As contemplated under the terms of the Commitment Letter, based upon receipt of the Term Loan Change of Control Waiver and the Indenture Change of Control Waiver, EHC and AmSurg elected to structure the Term Loan Facility as an incremental credit facility under the Existing Term Loan Credit Agreement and to reduce the Commitment Parties’ commitment to provide the Term Loan Facility by $3.4 billion, which reduced the related fees under the Commitment Letter. After giving effect to such reduction, the Commitment Parties’ remaining commitment to provide EHC and AmSurg with a term loan facility is approximately $1.9 billion.

In addition to the borrowing under its Existing Term Loan Credit Agreement and the Credit Facilities, all indebtedness under that certain Indenture, dated as of June 18, 2014, among EHC, the subsidiary guarantors from time to time parties thereto and Wilmington Trust, National Association as trustee (as amended by the First Supplemental Indenture, dated as of June 18, 2014, the Second Supplemental Indenture, dated as of September 10, 2014, the Third Supplemental Indenture, dated as of May 4, 2015, the Fourth Supplemental Indenture, dated as of November 23, 2015 and the Fifth Supplemental Indenture, dated as of January 25, 2016), will remain outstanding following the Mergers.

Newco expects to borrow on or before the effective date of the Mergers the funds available on such date under the Commitment Letter and to use the proceeds therefrom to consummate the Mergers and to refinance and repay certain existing indebtedness of EHC and AmSurg.

For a detailed description of the terms of the Financing, see “The Mergers—Financing of the Transaction” beginning on page 137.

Litigation Relating to the Mergers

Following the announcement of the proposed Mergers, a purported Envision stockholder filed a putative stockholder class action lawsuit against the members of the Envision Board and Barclays PLC in the Court of Chancery of the State of Delaware on July 15, 2016. The case is captioned Anderson v. Sanger et al. , C.A. No. 12561-CB (Del. Ch.) . On September 22, 2016, the plaintiff filed an amended complaint, which alleges that the members of the Envision Board violated their fiduciary duties in connection with the proposed Mergers and

that Barclays PLC aided and abetted those breaches. Among other remedies, the plaintiff seeks to enjoin the Mergers from proceeding or, alternatively, damages in the event the Mergers are consummated. The time for defendants to move or answer with respect to the amended complaint has not yet expired. We believe this lawsuit is without merit and intend to defend the lawsuit vigorously.

On August 31, 2016, a purported Envision stockholder filed a putative stockholder class action against Envision, the members of the Envision Board, AmSurg and Newco in the United States District Court for the District of Colorado. The case is captioned Voth v. Envision Healthcare Holdings, Inc. et al ., No. 1:16-cv-02213 (D. Colo.) . The lawsuit alleges that Envision and the members of the Envision Board violated Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder by disseminating a false and misleading registration statement in connection with the proposed Mergers and that the members of the Envision Board, AmSurg and Newco violated Section 20(a) of the Exchange Act by virtue of their purported status as controlling persons of Envision. Among other remedies, the plaintiff seeks to enjoin the Mergers from proceeding or, alternatively, rescission of the Mergers or damages in the event the Mergers are consummated. On September 30, 2016, the plaintiff filed a motion for expedited discovery. The time for defendants to respond to the motion or to move or answer with respect to the complaint has not yet expired. We believe this lawsuit is without merit and intend to defend the lawsuit vigorously.

On September 8, 2016, a purported Envision stockholder filed a putative stockholder class action against Envision, the members of the Envision Board, AmSurg and Newco in the United States District Court for the District of Colorado. The case is captioned LeMay v. Envision Healthcare Holdings, Inc. et al. , No. 1:16-cv-02265 (D. Colo.) . The lawsuit alleges that Envision and the members of the Envision Board violated Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder by disseminating a false and misleading registration statement in connection with the proposed Mergers and that the members of the Envision Board, AmSurg and Newco violated Section 20(a) of the Exchange Act by virtue of their purported status as controlling persons of Envision. Among other remedies, the plaintiff seeks to enjoin the Mergers from proceeding or, alternatively, rescission of the Mergers or damages in the event the Mergers are consummated. The time for defendants to move or answer with respect to the complaint has not yet expired. We believe this lawsuit is without merit and intend to defend the lawsuit vigorously.

The Special Meetings

The AmSurg Special Meeting (see page 53)

The AmSurg special meeting will be held at the offices of Bass, Berry & Sims PLC at 150 Third Avenue South, Suite 2800, Nashville, Tennessee 37201, on November 28, 2016, at 11:00 a.m., central time. At the AmSurg special meeting, AmSurg common shareholders will be asked to consider and vote upon:

You may vote at the AmSurg special meeting if you owned shares of AmSurg common stock at the close of business on October 7, 2016, which we refer to as the AmSurg record date. As of the close of business on the AmSurg record date, there were 54,803,561 shares of AmSurg common stock outstanding and entitled to vote. You may cast one vote for each share of AmSurg common stock that you owned as of the close of business on the AmSurg record date.

The holders of the AmSurg Preferred Stock are not entitled to vote at the AmSurg special meeting, nor are they required to take any other action in connection with the Mergers or the issuance of the Newco Series A-1 Preferred Stock. If Merger 1 is approved, the conversion of the AmSurg Preferred Stock into shares of Newco Series A-l Preferred Stock will occur automatically.

As of the close of business on the AmSurg record date, approximately 2.3% of the outstanding shares of AmSurg common stock were held by AmSurg’s directors and executive officers and their affiliates. We currently expect that AmSurg’s directors and executive officers will vote their AmSurg shares in favor of the above-listed proposals, although none of them has entered into any agreements obligating him or her to do so.

AmSurg common shareholder approval of the AmSurg Merger Proposal is required to complete the Mergers. The affirmative vote of a majority of the outstanding shares of AmSurg common stock entitled to vote on such proposal is required to approve the AmSurg Merger Proposal. The votes cast in favor of the AmSurg Compensation Proposal must exceed the votes cast against it to approve the AmSurg Compensation Proposal. The votes cast in favor of the AmSurg Adjournment Proposal must exceed the votes cast against it to approve the AmSurg Adjournment Proposal.

The AmSurg Board unanimously recommends that AmSurg common shareholders vote “FOR” all of the proposals set forth above, as more fully described under “The AmSurg Special Meeting” beginning on page 53.

The Envision Special Meeting (See page 59)

The Envision special meeting will be held at The Inverness Hotel and Conference Center, located at 200 Inverness Drive West, Englewood, Colorado 80112, on November 28, 2016, at 10:00 a.m., mountain time. At the Envision special meeting, Envision stockholders will be asked:

You may vote at the Envision special meeting if you owned shares of Envision common stock at the close of business on October 7, 2016, which we refer to as the Envision record date. As of the close of business on the Envision record date, there were 187,312,960 shares of Envision common stock outstanding and entitled to vote. You may cast one vote for each share of Envision common stock that you owned as of the close of business on the Envision record date.

As of the close of business on the Envision record date, approximately 1.0% of the outstanding shares of Envision common stock were held by Envision’s directors and executive officers and their affiliates. We currently expect that Envision’s directors and executive officers will vote their Envision shares in favor of the above-listed proposals, although none of them has entered into any agreements obligating him or her to do so.

Completion of the Mergers is conditioned on approval of the Envision Merger Proposal. Approval of the Envision Merger Proposal requires the affirmative vote of a majority of all outstanding shares of the Envision common stock entitled to vote on such proposal. Approval of the Envision Compensation Proposal requires the affirmative vote of a majority of the outstanding shares of Envision common stock present in person or represented by proxy at the Envision special meeting entitled to vote on such proposal. Approval of the Envision Adjournment Proposal requires the affirmative vote of a majority of the outstanding shares of Envision common stock present in person or represented by proxy at the Envision special meeting entitled to vote on such proposal.

The Envision Board unanimously recommends that Envision stockholders vote “FOR” all of the proposals set forth above, as more fully described under “The Envision Special Meeting” beginning on page 59.

No Appraisal/Dissenters’ Rights

Under Section 48-23-102 of the TBCA, the holders of AmSurg common stock and AmSurg Preferred Stock do not have the right to dissent in connection with the Mergers.

Under Section 262 of the DGCL, the holders of Envision common stock do not have appraisal rights in connection with the Mergers.

See “No Appraisal/Dissenters’ Rights” on page 211 for more information on appraisal/dissenters’ rights.

Accounting Treatment of the Mergers

The combined company will account for the Mergers using the acquisition method of accounting in accordance with accounting principles generally accepted in the United States of America (“U.S.GAAP”) and Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 805, “Business Combinations” (“ASC 805”). Although the business combination of AmSurg and Envision is a “merger of equals,” U.S.GAAP requires that one of the two companies in the merger be designated as the acquirer for accounting purposes based on the evidence available. Accordingly, AmSurg will be treated as the acquiring entity for accounting purposes. In identifying AmSurg as the acquiring entity, the companies took into account the structure of the transaction, the composition of the governing body of the combined company and the designation of certain senior management positions of the combined company. As a result, the historical financial statements of AmSurg will become the historical financial statements of the combined company.
