PROXY STATEMENT

We are furnishing this Proxy Statement and related materials to MEDNAX’s shareholders as part of the solicitation of proxies by MEDNAX’s Board of Directors for use at MEDNAX’s 2018 Annual Shareholders’ Meeting and at any postponement or adjournment of the meeting. As used in this Proxy Statement, unless the context otherwise requires, the terms “MEDNAX,” “we,” “us,” “our” and the “Company” refer to the parent company, MEDNAX, Inc., a Florida corporation, and the consolidated subsidiaries through which its businesses are actually conducted, together with MEDNAX’s affiliated business corporations or professional associations, professional corporations, limited liability companies and partnerships. All share and per share data set forth herein give effect to the two-for-one splits of our common stock that became effective on April 13, 2006 and December 19, 2013.

On December 31, 2008, Pediatrix Medical Group, Inc., a Florida corporation (“Pediatrix”), and MEDNAX completed a holding company formation transaction that established MEDNAX as the parent company of Pediatrix, now known as MEDNAX Services, Inc. Throughout this Proxy Statement, when we refer to MEDNAX or to the Company in reference to activities that occurred prior to the reorganization on December 31, 2008, we are referring to Pediatrix, and when we refer to the Company in reference to activities occurring after the reorganization, we are referring to MEDNAX, except to the extent the context otherwise indicates.

Under the rules and regulations of the SEC, we are furnishing our proxy materials to our shareholders over the Internet and providing a Notice of Internet Availability of Proxy Materials (the “E-Proxy Notice”) by mail instead of mailing a printed copy of our proxy materials, which include our Proxy Statement and Annual Report, to all MEDNAX shareholders. The E-Proxy Notice will instruct you on how you may access and review all of the important information contained in the proxy materials. The E-Proxy Notice also instructs you how you may submit your proxy via the Internet. You will not receive a printed copy of the proxy materials unless you request to receive these materials in hard copy by following the instructions provided in the E-Proxy Notice.

We are mailing the E-Proxy Notice on or about March 30, 2018, to MEDNAX’s shareholders of record at the close of business on March 12, 2018.

QUESTIONS AND ANSWERS ABOUT OUR ANNUAL MEETING

What Is the Date, Time and Place of the Annual Meeting?

MEDNAX’s 2018 Annual Shareholders’ Meeting will be held on Wednesday, May 16, 2018, beginning at 9:30 a.m. (ET) at the DoubleTree by Hilton Sunrise, 13400 West Sunrise Boulevard, Sunrise, Florida, 33323.

What Is the Purpose of the Annual Meeting?

At the annual meeting, MEDNAX’s shareholders will be asked to:

1

Who Is Entitled to Vote at the Annual Meeting?

Only holders of record of our common stock at the close of business on March 12, 2018, the record date for the meeting, are entitled to notice of, to attend and to vote at the annual meeting, or any postponements or adjournments of the meeting. At the close of business on the record date, 94,382,958 shares of our common stock were issued and outstanding and were held by approximately 372 holders of record.

What Are the Voting Rights of MEDNAX’s Shareholders?

MEDNAX’s shareholders have one vote per share of MEDNAX common stock owned on the record date for each matter properly presented at the annual meeting. For example, if you owned 100 shares of our common stock at the close of business on March 12, 2018, you can cast 100 votes for each matter properly presented at the annual meeting.

What Constitutes a Quorum?

A quorum will be present at the meeting if holders of a majority of the issued and outstanding shares of our common stock on the record date are represented at the meeting in person or by proxy. If a quorum is not present at the meeting, MEDNAX expects to postpone or adjourn the meeting to solicit additional proxies. Abstentions, including broker non-votes (as described below), will be counted as shares present and entitled to vote for the purposes of determining the presence or absence of a quorum.

What Are “Broker Non-Votes”?

“Broker non-votes” occur when shares held by a brokerage firm are not voted with respect to a proposal because the firm has not received voting instructions from the shareholder and the firm does not have the authority to vote the shares at its discretion. Under the rules of the New York Stock Exchange, brokerage firms may have the authority to vote their customers’ shares on certain routine matters for which they do not receive voting instructions, including the ratification of the appointment of independent auditors. The election of directors and the advisory vote on executive compensation are considered “non-routine” matters under the New York Stock Exchange rules. In addition, other matters may properly be brought before the meeting that may be considered “non-routine” under the applicable New York Stock Exchange rules. Shares held by a brokerage firm will not be voted on such non-routine matters by a brokerage firm unless it has received voting instructions from the shareholder and, accordingly, any such shares will be “broker non-votes.”

How Are Abstentions and Broker Non-Votes Treated?

Abstentions and broker non-votes are counted as present for purposes of determining the presence of a quorum. Abstentions and broker non-votes will not be counted as votes cast either in favor of or against the election of the nominees for Director or the advisory vote on executive compensation. Abstentions will not be counted as votes cast either in favor of or against the ratification of the appointment of our independent auditors.

Will My Shares Be Voted if I Do Not Provide My Proxy?

If your shares are held in the name of a brokerage firm, they will not be voted by the brokerage firm except as described above if you do not give the brokerage firm specific voting instructions. If you are a registered shareholder and hold your shares directly in your own name, your shares will not be voted unless you provide a proxy or fill out a written ballot in person at the meeting.

2

How Do I Vote?

You can vote in any of the following ways:

To vote via the Internet:

To vote by telephone if you are a registered shareholder who received a paper proxy card:

To vote by mail if you are a registered shareholder who received a paper proxy card:

To vote if you hold your shares in “street name,” follow the instructions of your bank or broker or vote in person as described below.

To vote in person if you hold your shares in “street name”:

To vote in person if you are a registered shareholder:

What Vote Is Required for the Proposals?

Assuming that a quorum is present at the annual meeting, the nine Director nominees receiving the highest number of affirmative votes from holders of our common stock will be elected as Directors of MEDNAX.

MEDNAX has a majority voting policy as part of its corporate governance principles. The majority voting policy is applicable solely to uncontested elections, which are those elections in which the number of nominees for election is less than or equal to the number of directors to be elected. Under the majority voting policy, any nominee for director who receives more “withheld” votes than “for” votes in an uncontested election must submit a written offer to resign as director. Any such resignation will be reviewed by the Nominating and Corporate Governance Committee and, within 90 days after the election, the independent members of the Board of Directors will determine whether to accept, reject or take other appropriate action with respect to, the resignation, in furtherance of the best interests of MEDNAX and its shareholders.

Assuming that a quorum is present, ratification of the appointment of our independent registered public accounting firm and approval of the compensation of our named executive officers each requires a majority of the votes cast on the proposal at the annual meeting.

How Does the Board of Directors Recommend I Vote on the Proposals?

The Board of Directors recommends that you vote:

How Will My Proxy Holders Vote?

The enclosed proxy designates Roger J. Medel, M.D., our Chief Executive Officer, Dominic J. Andreano, our Senior Vice President, General Counsel and Secretary, and Vivian Lopez-Blanco, our Chief Financial Officer and Treasurer, each with full power of substitution, to hold your proxy and vote your shares. Dr. Medel, Mr. Andreano and Ms. Lopez-Blanco will vote all shares of our common stock represented by proxies properly submitted via telephone or the Internet or properly executed proxies received in time for the annual meeting in the manner specified by the holders of those shares. Dr. Medel, Mr. Andreano and Ms. Lopez-Blanco intend to vote all shares of our common stock represented by proxies properly submitted via telephone, or the Internet, or that are properly executed by the record holder but otherwise do not contain voting instructions, as follows:

Can I Change My Vote After I Have Voted?

Voting by telephone, over the Internet or by mailing a proxy card does not preclude a shareholder from voting in person at the meeting. A shareholder may revoke a proxy, whether submitted via telephone, the Internet or mailed, at any time prior to its exercise by filing with MEDNAX’s Secretary a duly executed revocation of proxy, by properly submitting, either by telephone, mail or Internet, a proxy to MEDNAX’s Secretary bearing a later date or by appearing at the meeting and voting in person. Attendance at the meeting will not itself constitute revocation of a proxy.

Who Pays for the Preparation of the Proxy Statement?

MEDNAX will bear the cost of the solicitation of proxies from its shareholders, including preparing, printing and mailing this Proxy Statement, should you request a printed copy of the proxy materials, and the E-Proxy Notice. In addition to solicitations by mail, MEDNAX’s Directors, officers and employees, and those of its subsidiaries and affiliates, may solicit proxies from shareholders by telephone or other electronic means or in person but will receive no additional compensation for soliciting such proxies. MEDNAX will cause banks and brokerage firms and other custodians, nominees and fiduciaries to forward solicitation materials to the beneficial owners of our common stock held of record by such banks, brokerage firms, custodians, nominees and fiduciaries. MEDNAX will reimburse such banks, brokerage firms, custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses in doing so.

PROPOSAL 1: ELECTION OF MEDNAX’S DIRECTORS

MEDNAX’s Amended and Restated Articles of Incorporation, as amended (our “Articles of Incorporation”), and Amended and Restated Bylaws provide that the number of Directors constituting MEDNAX’s Board of Directors will be determined from time to time by resolution adopted by MEDNAX’s Board of Directors. Upon the recommendation of the Nominating and Corporate Governance Committee, the nominees for Director to be elected at the annual meeting in 2018 by the holders of our common stock are as follows:

Please see below under “Directors and Executive Officers” for the biographies of these nominees for Director.

Each Director elected will serve for a term expiring at MEDNAX’s 2019 Annual Meeting of Shareholders, which is expected to be held in May 2019, or until his or her successor has been duly elected and qualified.

MEDNAX’s Board of Directors has no reason to believe that any nominee will refuse to act or be unable to accept election; however, in the event that a nominee for a directorship is unable to accept election or if any other unforeseen contingencies should arise, proxies will be voted for the remaining nominees and for such other person as may be designated by MEDNAX’s Board of Directors, unless the proxies provide otherwise.

If a quorum is present at the annual meeting, the nine nominees receiving the highest number of votes “FOR” election will be elected to the Board of Directors of MEDNAX, subject to the majority voting policy described above. Proxies will be voted “FOR” all such nominees absent contrary instructions.

MEDNAX’s Board of Directors recommends a vote “FOR” the election of each of the nine nominees for Director.

GOVERNANCE AND RELATED MATTERS

Our business, property and affairs are managed under the direction of our Board of Directors, except with respect to those matters reserved for our shareholders. Our Board of Directors establishes our overall corporate policies, reviews the performance of our senior management in executing our business strategy and managing our day-to-day operations and acts as an advisor to our senior management. Our Board of Directors’ mission is to further the long-term interests of our shareholders. Members of the Board of Directors are kept informed of MEDNAX’s business through discussions with MEDNAX’s management, primarily at meetings of the Board of Directors and its committees, and through reports and analyses presented to them. Significant communications between our Directors and senior management occur apart from such meetings.

Questions and Answers About Our Corporate Governance Practices

What Committees Have Our Board of Directors Established?

The standing committees of MEDNAX’s Board of Directors are the Executive Committee, the Audit Committee, the Compensation Committee, the Nominating and Corporate Governance Committee and the Medical Science and Technology Committee. Copies of the charters for these committees, as well as our corporate governance principles, are available on our website at www.mednax.com. Our website and the information contained therein, other than material expressly referred to in this Proxy Statement, or connected thereto, are not incorporated into this Proxy Statement. A copy of our committee charters and corporate governance principles are also available upon request from MEDNAX’s Secretary at 1301 Concord Terrace, Sunrise, Florida 33323.

How Many Times Did Our Board of Directors Meet During 2017?

During 2017, MEDNAX’s Board of Directors held eight meetings. Committees of the Board of Directors held a combined total of 18 meetings and also took various actions by unanimous written consent. Each Director attended at least 75% of the total number of meetings of MEDNAX’s Board of Directors and its committees held during 2017 during the period he or she was a member thereof. Although MEDNAX has no formal policy with respect to its Directors’ attendance at MEDNAX’s Annual Shareholders’ Meetings, in 2017 all of our Directors attended the Annual Shareholders’ Meeting.

Are a Majority of Our Directors Independent?

Our Board of Directors has reviewed information about each of our non-employee Directors and made the determination that all of the non-employee Directors on our Board of Directors are independent. In arriving at this conclusion, our Board of Directors made the affirmative determination that each of Drs. Carlo, Goldschmidt and Sosa, Ms. Barker and Messrs. Alvarez, Fernandez, Gabos and Kadre and Donna E. Shalala, Ph.D., who resigned from our Board of Directors effective March 7, 2018, meet the Board of Directors’ previously adopted categorical standards for determining independence in accordance with the New York Stock Exchange’s corporate governance rules. In making this determination, the Board of Directors considered transactions and relationships between each Director or any member of his or her immediate family and MEDNAX and its subsidiaries and affiliates. These transactions consisted of those transactions reported below under “Certain Relationships and Related Person Transactions — Transactions with Related Persons.” Our Board of Directors determined that each of these transactions and relationships was within the New York Stock Exchange standards and our categorical standards and that none of the transactions or relationships affected the independence of the Director involved. Our adopted categorical standards for determining independence in accordance with the New York Stock Exchange’s corporate governance rules are contained in our corporate governance principles, a copy of which is available on our Website at www.mednax.com.

Who Are the “Chairman of the Board” and “Lead Independent Director”?

To assist the Board of Directors in fulfilling its obligations, following each annual meeting of the shareholders, MEDNAX’s Board of Directors designates a non-management Director as “Chairman of the Board.” In addition, the Board of Directors, by a majority vote of the non-management Directors, may also designate a non-management Director as “Lead Independent Director.”

MEDNAX separates the roles of Chief Executive Officer and Chairman of the Board in recognition of the differences between the two roles. The Chief Executive Officer is responsible for determining the strategic direction for the Company and the day-to-day leadership and performance of the Company. The principal responsibility of the Chairman of the Board is to serve as chief administrative liaison between independent Directors and MEDNAX management and to monitor implementation of Board of Directors’ directives and actions. The principal responsibility of the Lead Independent Director, if designated, is to work collaboratively

6

with the Chairman of the Board and the Chief Executive Officer with respect to Board of Directors governance and process. The Lead Independent Director has additional responsibilities and authorities set out in our corporate governance principles.

At least once a year, the Chairman of the Board or Lead Independent Director also presides over meetings of our independent Directors. Following our 2017 annual meeting of shareholders, our Board of Directors appointed Mr. Alvarez to serve as Chairman of the Board and Mr. Kadre to serve as Lead Independent Director.

What Role Does the Board of Directors Serve in Risk Oversight for the Company?

The Board of Directors provides oversight of the Company’s risk exposure by receiving periodic reports from senior management regarding matters relating to financial, operational, regulatory, legal and strategic risks and mitigation strategies for such risks. In addition, as reflected in the Audit Committee Charter, the Board of Directors has delegated to the Audit Committee responsibility to oversee, discuss and evaluate the Company’s policies and guidelines with respect to risk assessment and risk management, including internal control over financial reporting. As appropriate, the Audit Committee provides reports to and receives direction from the full Board of Directors regarding the Company’s risk management policies and guidelines, as well as the Audit Committee’s risk oversight activities.

How Can Shareholders Communicate with the Board of Directors?

Anyone who has a concern about MEDNAX’s conduct, including accounting, internal controls or audit matters, may communicate directly with our Chairman of the Board of Directors, Lead Independent Director, our non-management Directors, the Chairman of the Audit Committee or the Audit Committee. Such communications may be confidential or anonymous, and may be submitted in writing to the Chief Compliance Officer, MEDNAX, Inc., 1301 Concord Terrace, Sunrise, Florida 33323, or reported by phone at 877-835-5764. Any such concerns will be forwarded to the appropriate Directors for their review, and will be simultaneously reviewed and addressed by the Company’s General Counsel or Chief Compliance Officer in the same way that other concerns are addressed by us. MEDNAX’s Code of Conduct, which is discussed below, prohibits any employee from retaliating or taking any adverse action against anyone for raising or helping to resolve an integrity concern.

Has MEDNAX Adopted a Code of Conduct?

MEDNAX has adopted a Code of Conduct that applies to all Directors, officers, employees and independent contractors of MEDNAX and its affiliated professionals. MEDNAX intends to disclose any amendments to, or waivers from, any provision of the Code of Conduct that applies to any of MEDNAX’s executive officers or Directors by posting such information on its website at www.mednax.com.

MEDNAX has also adopted a Code of Professional Conduct — Finance that applies to all employees with access to, and responsibility for, matters of finance and financial management, including MEDNAX’s Chief Executive Officer, Chief Financial Officer and Treasurer and Chief Accounting Officer. MEDNAX intends to disclose any amendments to, or waivers from, any provision of the Code of Professional Conduct — Finance that applies to any of MEDNAX’s Chief Executive Officer, Chief Financial Officer and Treasurer, Chief Accounting Officer or persons performing similar functions by posting such information on its website at www.mednax.com.

Copies of our Code of Conduct and the Code of Professional Conduct — Finance are available on our website at www.mednax.com and upon request from MEDNAX’s Secretary at 1301 Concord Terrace, Sunrise, Florida 33323.

Has MEDNAX Adopted a Clawback Policy?

MEDNAX has adopted a Clawback Policy that permits the Company to seek to recover certain amounts of incentive compensation, including both cash and equity, paid to any executive officer (as defined in the

7

Securities Exchange Act of 1934, as amended (the “Exchange Act”)) on or after January 1, 2014, if payment of such compensation was based on the achievement of financial results that were subsequently the subject of a restatement of its financial statements due to misconduct, and if the executive engaged in improper conduct that materially contributed to the need for restatement, and a lower amount of incentive compensation would have been earned based on the restated financial results.

Does MEDNAX Require its Executive Officers and Board of Directors to Retain a Certain Amount of MEDNAX Common Stock?

MEDNAX has adopted a Stock Ownership and Retention Policy which requires that each named executive officer and each non-management Director retain MEDNAX common stock worth a certain multiple of annual base salary, or cash retainer, respectively. Details of the policy and the required ownership levels are described in further detail in the “Executive Compensation: Compensation Discussion and Analysis” section of this Proxy Statement.

Has MEDNAX Adopted an Anti-Hedging and Anti-Pledging Policy?

MEDNAX has adopted a policy prohibiting its directors, management, financial and other insiders from engaging in transactions in MEDNAX securities or derivatives of MEDNAX securities that might be considered hedging, or from holding MEDNAX securities in margin accounts or pledging MEDNAX securities as collateral for a loan, unless such person clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities.

Does MEDNAX Have a Director Retirement Age Policy?

MEDNAX has adopted a Director Retirement Age Policy which provides that a Director must retire and may not stand for re-election during the calendar year in which he or she attains age 80. Additionally, no Director may be nominated to a new term if he or she would attain age 80 by the end of the calendar year in which the election is held.

Report of the Audit Committee

The following report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any of MEDNAX’s filings under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except to the extent that we specifically incorporate such report by reference.

We act under a written charter that has been adopted by MEDNAX’s Board of Directors. While we have the responsibilities set forth in this charter, it is not our duty to plan or conduct audits or to determine that MEDNAX’s financial statements are complete, accurate or in compliance with accounting principles generally accepted in the United States (“GAAP”). This is the responsibility of MEDNAX’s management and independent auditors.

Our primary function is to assist the Board of Directors in their evaluation and oversight of the integrity of MEDNAX’s financial statements and internal control over financial reporting, the qualifications and independence of MEDNAX’s independent auditors and the performance of MEDNAX’s audit functions. In addition, while we are also responsible for assisting the Board of Directors in their evaluation and oversight of MEDNAX’s compliance with applicable laws and regulations, it is not our duty to assure compliance with such laws and regulations or MEDNAX’s Compliance Plan and related policies. We are also responsible for overseeing, discussing and evaluating MEDNAX’s guidelines, policies and processes with respect to risk assessment and risk management and the steps management has taken to monitor and control risk exposure, and we advise the Board of Directors with respect to such matters, as appropriate.

8

We also oversee MEDNAX’s auditing, accounting and financial reporting processes generally. Management is responsible for MEDNAX’s financial statements and the financial reporting process, including the system of internal controls. We also review the preparation by management of MEDNAX’s quarterly and annual financial statements. MEDNAX’s independent auditors, who are accountable to us, are responsible for expressing an opinion as to whether the consolidated financial statements present fairly, in all material respects, the financial position, results of operations and cash flows of MEDNAX in conformity with GAAP. MEDNAX’s independent auditors are also responsible for auditing and reporting on the effective operation of MEDNAX’s internal control over financial reporting. We are responsible for retaining MEDNAX’s independent auditors and maintain sole responsibility for their compensation, oversight and termination. We are also responsible for pre-approving all non-audit services to be provided by the independent auditors, and on an annual basis discussing with the independent auditors all significant relationships they have with MEDNAX to determine their independence.

In fulfilling our oversight role, we met and held discussions with MEDNAX’s management and independent auditors. Management advised us that MEDNAX’s consolidated financial statements were prepared in accordance with GAAP, and we reviewed and discussed the consolidated financial statements for the fiscal year ended December 31, 2017. In addition, we reviewed and discussed the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of MEDNAX’s periodic reports, key accounting and reporting issues and the scope, adequacy and assessments of MEDNAX’s internal controls and disclosure controls and procedures with management and MEDNAX’s independent auditors. We discussed privately with the independent auditors matters deemed significant by the independent auditors, including those matters required to be discussed pursuant to U.S. Auditing Standard No. 16 (Communications with Audit Committees), as adopted by the Public Company Accounting Oversight Board.

The independent auditors also provided us with the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board, regarding the independent accountant’s communications with the Audit Committee concerning independence, and we discussed with the independent auditors matters relating to their independence. We also reviewed a report by the independent auditors describing the firm’s internal quality-control procedures and any material issues raised in the most recent internal-quality control review or external peer review or inspection performed by the Public Company Accounting Oversight Board.

Based on our review with management and the independent auditors of MEDNAX’s audited consolidated financial statements and internal controls over financial reporting and the independent auditors’ report on such financial statements and their evaluation of MEDNAX’s internal controls over financial reporting, and based on the discussions and written disclosures described above and our business judgment, we recommended to the Board of Directors that the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2017 be included in MEDNAX’s Annual Report on Form 10-K for the year ended December 31, 2017, for filing with the SEC.

Submitted by the Audit Committee of the Board of Directors.

Certain Relationships and Related Person Transactions

Review and Approval of Related Person Transactions

MEDNAX has a written policy for the review and approval or ratification of transactions (i) between MEDNAX and any MEDNAX Director or any other entity in which any MEDNAX Director is a director, officer or has a financial interest; and (ii) in which MEDNAX is or will be a participant and any related person has or will have a direct or indirect material interest. For purposes of the policy, a related person includes any MEDNAX Director or Director nominee, executive officer or holder of more than 5% of the outstanding voting stock of MEDNAX or any of their respective immediate family members. The policy does not apply to transactions pertaining to (i) director or officer compensation that is approved or recommended to MEDNAX’s Board of Directors for approval by MEDNAX’s Compensation Committee or (ii) the employment by MEDNAX of any immediate family member of a related person in a non-officer position and at compensation levels commensurate with that paid to other similarly situated employees.

Pursuant to the terms of the policy, all covered transactions, if determined to be material by MEDNAX’s General Counsel or if the transaction involves the participation of a member of the MEDNAX Board of Directors, are required to be promptly referred to the disinterested members of the MEDNAX Audit Committee for their review or, if less than a majority of the members of MEDNAX Audit Committee are disinterested, to all the disinterested members of the MEDNAX Board of Directors. Pursuant to the terms of the policy, materiality determinations must be based on the significance of the information to investors in light of all circumstances, including, but not limited to, the (i) relationship of the related persons to the covered transaction, and with each other, (ii) importance to the person having the interest, and (iii) amount involved in the transaction. All transactions involving in excess of $120,000 are automatically deemed to be material pursuant to the terms of the policy.

The disinterested Directors of MEDNAX’s Audit Committee or Board of Directors, as applicable, are required to review such material covered transactions at their next regularly-scheduled meeting, or earlier if a special meeting is called by the Chairman of the Audit Committee and may only approve such a material covered transaction if it has been entered into in good faith and on fair and reasonable terms that are no less favorable to MEDNAX than those that would be available to MEDNAX in a comparable transaction in arm’s length dealings with an unrelated third party at the time it is considered by the disinterested Directors of MEDNAX’s Audit Committee or Board of Directors, as applicable.

SECTION II: EXECUTIVE SUMMARY

2017 Business Highlights

Stability and building long-term value are at the core of everything we do. Our unique healthcare model has been in place for over 35 years, allowing us to focus on what is most important in our industry — taking great care of our patients and improving patient outcomes. In 2017, we continued to position ourselves for the future of healthcare by concentrating on our long-term growth strategy. We remained disciplined in our spending, highly-selective in our acquisitions and responsive to the changing healthcare landscape. We were challenged in 2017 by unexpected changes in payor mix, reduced patient volumes and increased pressures on practitioner compensation in critical markets. Key financial results for the last three fiscal years, including the impact of the challenges we faced in 2017, are highlighted below:

Earnings before interest, taxes and depreciation and amortization (“EBITDA”) is a non-GAAP financial measure. For a description of the rationale for our presentation of EBITDA and a reconciliation of EBITDA to net income, the most directly comparable GAAP measure, for the years ended December 31, 2017, 2016 and 2015, please see the disclosure under the caption “Non-GAAP Measures” beginning on page 53 of our Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 14, 2018.

Our proven track record is also validated by the growth of our diluted earnings per share and annual cash flow from operations over the last 10 years.

Note: All share and per share amounts for all periods presented and discussed in this Proxy Statement reflect the two-for-one stock split effected in 2013.

Despite the company’s continued growth, since 2011, Dr. Medel’s salary has been $1,000,000 and his target bonus opportunity has been 150% of salary. His average bonus paid over the last ten years has been approximately 135% of salary or 90% of target. Dr. Medel’s bonus exceeded 170% of salary in only two out of those 10 years. The updated market analysis conducted during 2017 found that the median peer target bonus for chief executive officers was 125% of salary. That same analysis found that over the 2011-2016 period, the actual peer CEO bonus was 130% of salary at the median and 176% of salary at the 75^th percentile. In October 2017, Dr. Medel agreed to a three-year extension of his Employment Agreement, with no changes to his compensation.

SECTION III: OVERVIEW OF THE EXECUTIVE COMPENSATION PROGRAM

The Guiding Principles of Our Pay Philosophy

The Compensation Committee has designed our executive compensation program with the following guiding principles in mind:

19

Elements of Pay

Our pay philosophy is supported by the following pay elements in our executive compensation program:

Pay Mix

The charts below show that most of our NEOs’ total direct compensation is variable (86% for the CEO and an average of 81% for our other NEOs) based upon actual awarded and anticipated 2017 compensation:

How Pay Decisions Are Made

The Compensation Committee, composed solely of independent Directors, is responsible for making pay decisions for the NEOs. The Compensation Committee works very closely with its independent consultant, which for 2017 was Willis Towers Watson & Co. (“Willis Towers Watson”), and management to examine pay and performance matters throughout the year. The Compensation Committee held six meetings over the course of 2017, and took various other actions via unanimous written consent. The Compensation Committee’s written charter can be accessed on the MEDNAX website at www.mednax.com.

20

The Role of the Compensation Committee and Management

The primary role of the Compensation Committee is to assist MEDNAX’s Board of Directors in the discharge of the Board’s responsibilities related to executive compensation matters. The Compensation Committee’s responsibilities include:

The CEO does not play any role in the Compensation Committee’s determination of his own pay; however, the Compensation Committee solicits input from the CEO concerning the performance and compensation of the other NEOs. The CEO bases his recommendations on his assessment of each individual’s performance, tenure and experience in the role, external market pay practices, retention risk and MEDNAX’s overall pay philosophy.

The Role of Independent Consultants

The Compensation Committee continually reviews executive compensation to ensure that it reflects our pay philosophy and, as necessary, retains the services of an independent consultant to assist in such review. During 2017, the Compensation Committee retained Willis Towers Watson to provide data and analysis with respect to the compensation paid to our NEOs. The Compensation Committee has assessed the independence of Willis Towers Watson pursuant to applicable SEC rules, New York Stock Exchange listing standards and its own committee charter and concluded that no conflict of interest exists that would prevent Willis Towers Watson from independently advising the Compensation Committee.

Assessing External Market Practice

As part of our pay philosophy, our executive compensation program is designed to attract, motivate and retain our executives in an increasingly competitive and complex talent market. To this end, we regularly evaluate industry-specific and general market compensation practices and trends to ensure that our program features and NEO pay opportunities remain appropriately competitive. The Compensation Committee considers publicly available data, provided by its independent compensation consultant, for informational purposes when making its pay decisions. However, market data are not the sole determinants of the Company’s practices or executive pay levels. When determining salaries, target bonus opportunities and annual equity grants for NEOs, the Compensation Committee also considers the performance of the Company and the individual, the nature of an individual’s role within the Company, internal comparisons to the compensation of other Company officers, tenure with the Company and experience in the officer’s current role.

21

During 2016, the Compensation Committee reviewed CEO compensation information from a group of 16 publicly traded healthcare services companies. The companies included in the analysis were recommended by the Committee’s consultant and approved by the Committee. During the fall of 2017, the consultant updated the peer analysis for the CEO position as well as for the Company’s other NEOs. The companies included in our peer group were as follows:

In determining the peer group for the studies, the Compensation Committee considered a variety of factors including revenue, income from operations, net income, market capitalization and enterprise value. Based on the advice of its consultant, the Compensation Committee established that top executive pay levels at publicly-traded companies in the healthcare services industry were more closely correlated to factors other than revenue. As such, the peer group was determined with an objective of placing MEDNAX near the median for both income from operations and enterprise value. Given MEDNAX’s profitability, this meant that MEDNAX would rank in the lower quartile of its peers in terms of revenue and in the upper quartile of its peers in terms of net income and market capitalization.

An updated analysis of the remaining peer companies showed that as of year-end 2016, MEDNAX ranked near the peer 25^th percentile in terms of revenue, at the peer 57^th percentile in terms of operating income, near the peer 80^th percentile in terms of net income, near the peer 60^th percentile in terms of enterprise value and near the peer 70^th percentile in terms of market capitalization. MEDNAX also ranked between the peer 35^th and 50^th percentiles for three-year growth rates in revenues, income from operations and net income , and above the peer median for annualized total shareholder return over the past three and five year periods. Data from the updated peer analysis are summarized in the tables below:

22

The Compensation Committee reviews a variety of other areas including key incentive design features, equity grant programs, historical CEO bonus payout levels, stock ownership policies, Board of Directors compensation and other policies relating to officer and Board member compensation from time to time relative to MEDNAX’s peers. In addition, the Compensation Committee periodically reviews information relating to NEO compensation practices as developed from companies considered to be MEDNAX peers by proxy advisory firms. However, since some of these advisory firms determine peers based primarily on comparable revenue, the Compensation Committee has not used information from these companies in evaluating NEO salaries, bonus opportunities and annual equity-based award values. The Compensation Committee believes that information from the peer group it has selected is more relevant.

SECTION IV: THE EXECUTIVE COMPENSATION PROGRAM IN DETAIL

Base Salary

The Compensation Committee reviews and approves base salary levels at the beginning of each year. Base salary decisions generally reflect the Compensation Committee’s consideration of the external market practices of our peer group for comparable positions, published survey data, and subjective factors including the individual’s experience, role, responsibilities and performance.

2017 Base Salary Decisions

The 2017 base salaries for the NEOs were as follows:

23

2017 Annual Bonus Decisions

The Compensation Committee establishes each NEO’s maximum annual bonus opportunity as a percentage of base salary in effect at the beginning of the year. The target bonus opportunity for each NEO is equal to 50% of the NEO’s maximum bonus opportunity. The Committee, consistent with historical practice, established the minimum income from operations goal at a level equal to the income from operations achieved by the Company in the prior year. By the middle of the second quarter of 2017, it became clear that due to the various financial challenges the Company faced, the minimum income from operations level necessary for Dr. Medel, Mr. Calabro and Ms. Lopez-Blanco to earn a bonus was unlikely to be achieved. The Compensation Committee considered the adoption of a supplemental bonus program designed to motivate and incentivize the executive team to achieve incrementally higher income from operations in the second half of 2017. However, the Compensation Committee ultimately decided to maintain the original bonus plan for 2017. The Compensation Committee determined that the Company’s 2017 income from operations corresponded to a payment of 0% of the target bonus payment under the bonus guidelines for each of Dr. Medel, Ms. Lopez-Blanco and Mr. Calabro.

For 2017, the Chief Executive Officer and the President and Chief Operating Officer recommended and the Compensation Committee approved, the annual bonuses for Mr. Clark and Mr. Andreano that were consistent with those being paid to bonus-eligible employees, other than Dr. Medel, Ms. Lopez-Blanco and Mr. Calabro. The recommendations considered the financial performance results of the Company in 2017, the operating performance of the Company’s MEDNAX National Medical Group (in the case of Mr. Clark), the performance of the Company’s General Counsel’s office and legal function (in the case of Mr. Andreano), and the individual contributions of Mr. Clark and Mr. Andreano to the Company in 2017. The recommendations also took into account the updated market compensation references for Messrs. Clark’s and Andreano’s positions, noting that Messrs. Clark and Andreano’s base salaries were below the market median. In considering these factors, the Chief Executive Officer and the President and Chief Operating Officer recommended to the Compensation Committee that Mr. Clark and Mr. Andreano should each receive 75% of his target bonus opportunity, similar

24

to other bonus-eligible employees who earned 75% of their target bonuses based on their individual, departmental and Company performance. The Compensation Committee agreed with the recommendations and approved the bonuses for Messrs. Clark and Andreano.

Equity-Based Awards

2017 Equity-Based Awards

The Compensation Committee approved the June 1, 2017 equity-based awards outlined below in May 2017. These equity-based awards were divided equally into performance share awards and time-based restricted stock awards for each of Dr. Medel, Ms. Lopez-Blanco and Mr. Calabro. The equity grant values for Dr. Medel, Ms. Lopez-Blanco and Mr. Calabro remained the same in 2017 as they were in 2016. The actual number of shares earned from the June 1, 2017 award of restricted stock and performance shares granted to Dr. Medel, Ms. Lopez-Blanco and Mr. Calabro has not been determined as of the date of this Proxy Statement because the performance period for such awards will initially be measured over a one-year period from April 1, 2017 through March 31, 2018. Messrs. Clark and Andreano’s equity-based awards granted in 2017 are subject only to the 162(m) goal and time-based vesting requirements. In 2018, Messrs. Clark and Andreano were awarded performance shares subject to the same performance metrics as our other NEOs.

50% of the equity-based award is granted in performance shares that:

The approach described in the table above reflects the Compensation Committee’s desire to set rigorous performance goals in a highly volatile and uncertain environment, while also rewarding NEOs when the Company achieves these goals and delivers sustained results for our shareholders.

In setting financial performance goals for these performance share awards, the Compensation Committee received recommendations from management based on the Company’s strategic plan for the performance measurement period. The Compensation Committee, working with its independent compensation consultant and Company management, evaluated the impact of various drivers on revenue and EBITDA in determining the 2017 grants.

25

The 2017 performance goals were set to appropriately reflect specific factors that were expected to have a direct impact on the results for this performance period. The growth rate targets for the 2017 performance period differ from the Company’s historical 5-year average growth rates because of volatility in the various drivers that impact results from year to year. Other drivers considered in setting the performance goals included, but were not necessarily limited to: acquisition-related activities, including size, type, timing and volume of acquisitions, the continued diversification of our services, same-unit volume growth, expense-related initiatives and reimbursement-related factors, including payor mix. At the time the 2017 performance goals were being developed, the financial challenges faced by the Company were becoming apparent, but their full impact on future net revenue and EBITDA results was still highly uncertain. The Compensation Committee established net revenue and EBITDA goals that reflected the financial challenges and uncertain operating environment, particularly with regard to year-over-year changes in EBITDA, that the Compensation Committee felt were still rigorous yet achievable. At the time the goals were approved, the Company’s internal forecast for the Performance Share measurement period projected a significant decline in EBITDA and modest growth in net revenue. The Compensation Committee developed performance goals in light of these forecasts, noting that it would be extremely unlikely that an above-target award would be earned based on the financial forecasts at the time of the goal. Consideration was also given to those factors that impacted previous year results (positively or negatively) but were not anticipated to impact 2017 results. The Compensation Committee further elected to eliminate a retesting feature of the equity program that allowed an additional opportunity to earn performance shares if the performance criteria were not met during the initial performance period.

As the Company continues to grow, the base on which performance goals are set will continue to increase, and it will become increasingly challenging to maintain historical growth rates for both revenue and EBITDA. This factor was also taken into account when setting growth rate targets for the 2017 performance period.

The Committee believes the above approach used to establish financial performance goals for performance share awards results in goals that are challenging yet realistic and achievable, adequately rigorous and effective in continuing to motivate the executive team to drive the strong shareholder returns historically generated by the Company. Accordingly, the Committee believes the performance shares awarded appropriately align Company performance with executive compensation.

While this discussion of 2017 equity awards relates to growth targets for the 2017 performance period, we believe our approach to granting performance shares also creates long-term alignment, given that the value of the award realized by the NEOs will depend on the value of our stock when the shares vest over a multi-year period. As a result, we believe our NEOs are incentivized not only to execute the Company’s growth strategy but also to maintain discipline in its acquisition-related activities and processes in order to generate sustainable longer-term growth and increased shareholder value. We believe our approach also addresses our critical need to retain the highest-caliber executives in our industry — especially as the challenges in the healthcare sector grow increasingly more complex and competition for executive talent in the healthcare sector increases.

The table below outlines the 2017 equity award program:

Actual Performance and Shares Earned in 2017 for 2016 Performance Share Awards

For the period from April 1, 2016 to March 31, 2017, the Company’s net revenue and EBITDA, the metrics on which the 2016 performance share awards were measured, grew by 13.1%, in the case of net revenue and 2%, in the case of EBITDA. In accordance with the pre-established target growth rates of 8% to 14% for each of net revenue and EBITDA, our NEOs earned 100% and 25.5% of their target performance share awards for each metric, respectively, and 62.75% of their target performance share awards overall. The shares earned vest over the first three anniversaries of the grant date, subject to continued employment.

Restricted Stock Unit Awards

Based on the results of the updated NEO market analysis conducted in 2017, in December 2017 the Compensation Committee made supplemental grants to Messrs. Clark and Andreano of 14,741 and 9,828 performance-based restricted stock units (“RSUs”) respectively. These grants were designed to ensure that the total compensation of Messrs. Clark and Andreano was competitive with market references, particularly after the market analysis completed in the fall of 2017 indicated that the annual equity grants made in June 2017 to Messrs. Clark and Andreano were below the market median for each. The RSUs will vest on March 1, 2020 if the Company achieves consolidated EBITDA for the twelve months ended December 31, 2018 equal to or exceeding $440,000,000, and is subject to each executive’s continued employment.

Other Practices, Policies & Guidelines

Equity Grant Practices

The Compensation Committee determines the effective date of annual equity-based awards without regard to current or anticipated stock price levels. Although usually made around mid-year, the Compensation Committee may also make, and in the past has made, grants during the course of the year, primarily for new hires, promotions, to retain valued employees or to reward exceptional performance. These grants may be subject to performance conditions and/or time-based vesting, and are issued on the date of grant approval or upon a date certain following the grant approval date.

We follow equity grant procedures designed to promote the proper authorization, documentation and accounting for all equity grants. Pursuant to these procedures the Compensation Committee or the Board of Directors must formally approve all equity awards during an in person or telephonic meeting or by the unanimous written consent executed by all members of the Compensation Committee or the Board of Directors, as the case may be, it being understood that no equity award granted pursuant to any such written consent may have an effective date earlier than the date that all executed counterparts of such unanimous written consent are delivered to the General Counsel of the Company.

The grant-date fair value of our equity-based awards will be the closing sales price for a share of our common stock as reported on the New York Stock Exchange on the effective date of the grant as approved by the Compensation Committee or the Board of Directors, which date may not be prior to either the date such grant was approved or the commencement date of employment of the employee to whom the equity award is being made.

Our “insiders” can only buy or sell Company stock in accordance with our Insider Trading Policy, and our employees generally can only buy or sell Company stock in accordance with our Policy Statement on Inside Information and Insider Trading for All Employees.

NEOs are allowed to vote performance shares and restricted stock as a shareholder based on the number of shares held under restriction. Any dividends declared with respect to any performance share or restricted stock awards would be held until the awards vest, at which time the dividends would be paid to the NEOs. If performance shares or restricted stock are forfeited, the NEO’s rights to receive the dividends declared with respect to those shares would be forfeited as well. At present, the Company does not pay dividends and it has no current intention to do so in the future.

28

Clawback Policy

The Company has adopted a “clawback policy” that permits the Company to seek to recover certain amounts of incentive compensation, including both cash and equity, awarded to any executive officer (as defined in the Exchange Act ) on or after January 1, 2014 if payment of such compensation was based on the achievement of financial results that were subsequently the subject of a restatement of our financial statements due to misconduct, and if the executive officer engaged in improper conduct that materially contributed to the need for restatement, and a lower amount of incentive compensation would have been earned based on the restated financial results.

Stock Ownership and Retention Policy

The Compensation Committee believes that the Company’s Board of Directors and NEOs should maintain a material personal financial stake in the Company through the ownership of shares of the Company’s common stock to promote a long-term perspective in managing the enterprise and to align shareholder, director and executive interests.

Each of our NEOs are required to own shares of MEDNAX common stock with a value of not less than a specified multiple of his or her base salary. The policy also requires NEOs to retain 50% of net after-tax shares acquired during the year upon vesting (or exercise of stock options) unless his or her ownership level was satisfied as of the beginning of the year. These multiples were determined in accordance with current market practice.

The chart below shows the multiple of base salary ownership requirements and actual ownership levels as of December 31, 2017:

As the table above reflects, our NEOs hold a significant investment in MEDNAX, which is a strong reflection of our culture and aligns with our compensation philosophy.

Shares that count toward the ownership requirement are as follows:

The Compensation Committee will evaluate NEO ownership levels annually and will review this policy from time to time and, following consultation with the Board of Directors, make modifications as necessary or appropriate.

29

Anti-Hedging and Anti-Pledging Policy

All MEDNAX directors, management, financial and other insiders are prohibited from engaging in transactions in MEDNAX securities or derivatives of MEDNAX securities that might be considered hedging, such as selling short or buying or selling options. In addition, it is against the policy for such persons to hold securities in margin accounts or pledge MEDNAX securities as collateral for a loan, unless such person clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities.

Retirement and Deferred Compensation Plans

We maintain a Thrift and Profit Sharing Plan (the “401(k) Plan”), which is a 401(k) plan, to enable eligible employees to save for retirement through a tax-advantaged combination of elective employee contributions and our discretionary matching contributions, and provide employees the opportunity to directly manage their retirement plan assets through a variety of investment options. The 401(k) Plan allows eligible employees to elect to contribute from 1% to 60% of their eligible compensation to an investment trust on a pre-tax and/or Roth after-tax basis, up to the maximum dollar amounts permitted by law. The 401(k) Plan also offers employees the option to voluntarily contribute additional funds on a non-deductible after-tax basis subject to certain limits. In 2017, the maximum employee pre-tax and/or Roth elective contribution to the 401(k) Plan was $18,000, plus an additional $6,000 for employees who were at least 50 years old in 2017. Eligible compensation generally means all wages, salaries and fees for services from the Company, up to a maximum specified amount permitted by law. Matching contributions under the 401(k) Plan are discretionary. For 2017, the Company matched 100% of the first 4% of eligible compensation that each eligible participant contributed to the 401(k) Plan on his or her behalf. The portion of an employee’s account under the 401(k) Plan that is attributable to matching contributions vests as follows: 30% after one year of service, 60% after two years of service, and 100% after three years of service. However, regardless of the number of years of service, an employee is fully vested in our matching contributions (and the earnings thereon) if the employee retires at age 65 or later, or terminates employment by reason of death or total and permanent disability. The 401(k) Plan provides for a variety of different investment options, in which the employee’s and the Company’s contributions are invested.

Although the Company maintains a non-qualified deferred compensation plan, none of the NEOs participate in that Plan.

The amounts of the Company’s matching contributions under the 401(k) Plan for 2017 for each of the NEOs are included in the “All Other Compensation” column of the Summary Compensation Table.

Benefits and Perquisites

We provide our NEOs with certain benefits designed to protect them and their immediate families in the event of illness, disability, or death. We believe it is necessary to provide these benefits in order for us to be successful in attracting and retaining executives in a competitive marketplace, and to provide financial security in these circumstances. NEOs are eligible for health and welfare benefits available to similarly situated eligible Company employees during active employment under the same terms and conditions. These benefits include medical, dental, vision, short-term and long-term disability and group-term life insurance coverage.

Pursuant to the terms of their Employment Agreements, each of the NEOs are entitled to 38 days paid time off each year for vacation, illness, injury, personal days and other similar purposes in accordance with our policies in effect from time to time. Any paid time off not used during a calendar year may be carried over to the next year to the extent permitted under those policies. Dr. Medel and Mr. Calabro each are entitled under their Employment Agreements to utilize, for personal travel, the aircraft that the Company leases. Dr. Medel’s personal use of the aircraft may not exceed 95 hours of flight in any calendar year and Mr. Calabro’s personal use of the aircraft may not exceed 50 hours of flight in any calendar year without the consent of the Compensation Committee. The incremental cost to the Company of these benefits for Dr. Medel and Mr. Calabro is included in the “All Other Compensation” column of the Summary Compensation Table.

The Compensation Committee has reviewed our perquisites expenditures, and believes they continue to be an important element of the overall compensation package to retain current officers, and in fact command a higher perceived value than the actual cost.

Termination of Employment and Change in Control Agreements

As described in greater detail below, the Employment Agreements between the Company and each of the NEOs provide for the payment of certain compensation and benefits in the event of the termination of an executive’s employment, the amount of which varies depending upon the reason for such termination. The Compensation Committee has reviewed the essential terms of these termination provisions, and believes they are reasonable, appropriate, and generally consistent with market practice. Those provisions include a reimbursement by the Company to Mr. Calabro of any excise tax imposed upon the executive pursuant to Section 4999 of the Code with respect to any “excess parachute payments,” as that term is defined in Section 280G of the Code, that the executive receives as a result of a Change in Control. In the case of Dr. Medel, his current Employment Agreement provides that, if any amount payable to Dr. Medel in connection with a Change in Control would be subject to excise tax under Section 4999 of the Code, then the Company will reduce the payment to an amount equal to the largest portion of such payment that would result in no portion of such payment being subject to excise tax (unless such reduction would result in Dr. Medel receiving, on an after tax basis, an amount lower than the unreduced payment after taking into account all applicable federal, state and local employment taxes, income taxes and excise taxes, in which case the payment amount would not be reduced).

In certain situations pursuant to the terms of the award agreement or an executive’s Employment Agreement, the service requirement may be waived and vesting accelerated. However, in no situations except those involving a change-in-control of MEDNAX will any shares vest unless the performance goal has first been achieved.

Additionally, any unvested restricted stock is generally forfeited upon termination of the employment of the NEOs. The Employment Agreements with our NEOs provide however, that their restricted stock may vest or continue to vest after termination of employment in certain circumstances. In the event of termination of Dr. Medel and Mr. Calabro by the Company without Cause (as defined in his Employment Agreement) or due to the executive’s Disability (as defined in his Employment Agreement) or by the executive for Good Reason (as defined in his Employment Agreement), due to the executive’s health becoming impaired to any extent that makes the continued performance of his duties hazardous to the executive’s physical or mental health or life (“Poor Health”) or due to death, all restricted stock granted prior to termination of employment will continue to vest until fully vested. Furthermore, in the event of a Change in Control (as defined in his Employment Agreement), for Dr. Medel and Mr. Calabro, all unvested restricted stock will automatically vest. In the event that Ms. Lopez-Blanco’s or Messrs. Clark or Andreano’s employment is terminated due to Disability or death, all unvested restricted stock granted to her or him by the Company will continue to vest until fully vested following the termination of her or his employment. In the event that, at any time following a Change in Control (as defined in her or his Employment Agreement), Ms. Lopez-Blanco or Messrs. Clark and Andreano are terminated by the Company without Cause (as defined in her or his Employment Agreement) or by the executive for Good Reason (as defined in her or his Employment Agreement), provided that termination by the executive for Good Reason related to a diminution in duties following a Change in Control must occur within the 24-month period of a Change in Control, any unvested restricted stock will automatically vest.
