Report of Independent Registered Certified Public Accounting Firm
To the Participants and Administrator of
Pediatrix Medical Group Thrift and Profit Sharing Plan
In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of Pediatrix Medical Group Thrift and Profit Sharing Plan as amended and restated (the “Plan”) at December 31, 2006 and 2005, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule H, line 4i — Schedule of Assets (Held at End of Year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.
As discussed in Note 1, the Plan adopted Financial Accounting Standards Board Staff Position AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans, as of December 31, 2006 and 2005.

Pediatrix Medical Group
Thrift and Profit Sharing Plan
Notes to Financial Statements
December 31, 2006 and 2005
1.   Description of Plan
 
    Pediatrix Medical Group, Inc. (the “Company”) sponsors the Pediatrix Medical Group Thrift and Profit Sharing Plan as amended and restated (the “Plan”) which was adopted on January 1, 1991 and restated as amended in November 2002.
 
    The following description of the Plan is provided for general information purposes only. More complete information regarding items such as vesting, benefit provisions and plan termination may be found in the Plan document which is available to all participants upon request.
 
    General
The Plan is a tax qualified defined contribution plan covering substantially all of the Company’s eligible employees and the employees of the professional associations whose operations are consolidated with the Company. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).
 
    Eligibility and Entry Data
An employee becomes eligible to participate in the Plan on the first day of each calendar quarter after having attained age 21.
 
    Contributions
The Company may, at the discretion of its Board of Directors, contribute for each participant a matching contribution determined annually based on a percentage of the participant’s pre-tax contributions. In addition, the Company may also make discretionary profit sharing contributions to the Plan at amounts determined at the end of the Plan year by the Board of Directors.
 
    Effective April 1, 2002, participants may elect to make voluntary pre-tax contributions up to 60 percent of annual compensation including regular salary and wages, overtime pay, bonuses and commissions through payroll deductions. Previously, participants had the option to make voluntary pre-tax contributions, not to exceed 20 percent of their eligible compensation. Such contributions are excluded from the participant’s taxable income for federal income tax purposes until received as a withdrawal or distribution from the Plan. Contributions are subject to certain limitations. The maximum pre-tax contributions for the years ended December 31, 2006 and 2005 were $15,000 and $14,000, respectively. In addition to any pre-tax contributions, participants may make after tax contributions, not to exceed 10 percent of the participant’s compensation.
 
    The Plan provides that participants who are projected to be age 50 or older by the end of the calendar year and who are making deferral contributions to the Plan may also make catch-up contributions of up to $5,000 and $4,000 during the years ended December 31, 2006 and 2005, respectively.
 
    Rollovers
The Plan accepts rollover contributions from other tax-qualified plans for those participants who choose to invest in the Plan.
 
    Participant Accounts
Each participant’s account is credited with the participant’s contribution and an allocation of (a) the Company’s discretionary contributions and (b) the Plan’s earnings and losses. Allocation of the Plan’s earnings or losses in each investment option are made to the individual participant’s account based on the ratio of each participant’s current account balance in the respective investment option to total Plan participants’ account balances in the respective investment option. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

    Payment of Benefits
Upon normal retirement, death, disability or termination, participants may elect to receive their vested account balance as a lump-sum distribution; or have their account balance transferred to an individual retirement account or other qualified plan.
 
    Vesting
Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the portion of their accounts related to the Company’s contribution plus related earnings is based on years of credited service. A participant is fully vested after three years of credited service as follows:
         
    Vested  
Years of Service   Percentage  
Less than 1
     0 %
1
     30 %
2
     60 %
3
     100 %
    Participants Loans
Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of 50 percent of their account balance or $50,000 reduced by the highest outstanding loan balance in their account during the prior twelve month period. The loans are collateralized by the balance in the participant’s account and bear interest at rates ranging between 5.25% and 9.00%, which is commensurate with local prevailing rates as determined by the Plan Administrator. Repayments of principal and interest are credited back to the participant’s account through payroll deductions on a minimum of a quarterly basis. The term of the loan must not exceed five years, except for qualified home loans, which must not exceed ten years.
 
    Forfeitures
Forfeitures of the non-vested portion of participant’s account balances related to the Company’s contributions may be used to offset future Company contributions. Forfeitures held in the Plan totaled $62,022 and $107,385 at December 31, 2006 and 2005, respectively.
 
    Plan Termination
While the Company has not expressed any intent to terminate the Plan, it reserves the right at any time to amend, modify or terminate the Plan without the consent of any participant or beneficiary. In the event of such termination, the Plan provides that the participants shall become 100 percent vested in their accounts, including all employer contributions.
 
    Plan Administration
The Plan is administered by certain employees of the Company (the “Plan Administrator”). The Plan’s assets were maintained by Fidelity Management Trust Company (“Fidelity”), the trustee of the Plan, for the years ended December 31, 2006 and 2005.
     New Accounting Pronouncements
As of December 31, 2006, the Plan adopted Financial Accounting Standards Board (FASB) Staff Position FSP AAG INV-1 and Statement of Position No. 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined Contribution Health and Welfare and Pension Plans (the FSP). The FSP requires the Statements of Net Assets Available for Benefits present the fair value of the Plan’s investments as well as the adjustment from fair value to contract value for the fully benefit-responsive investment contracts. The Statements of Changes in Net Assets Available for Benefits is prepared on a contract value basis for the fully benefit-responsive investment contracts. The FSP was applied retroactively to the prior period presented on the Statement of Net Assets Available for Benefits as of December 31, 2005.
 
    In September 2006, the FASB issued Statement on Financial Accounting Standards No. 157 (SFAS 157), Fair Value Measurements. SFAS 157 establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurement. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. The Company is currently evaluating what impact the adoption of SFAS 157 will have on the financial statements.

2.   Summary of Significant Accounting Policies
 
    Basis of Accounting
The financial statements of the Plan are prepared under the accrual method of accounting in conformity with accounting principles generally accepted in the United States of America.
 
    Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions to net assets available for benefits during the reporting period. Actual results could differ from those estimates.
 
    Risks and Uncertainties
The Plan provides for various investment options. Investment securities are exposed to various risks, such as interest rate, market and credit risk. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits and the statements of changes in net assets available for benefits.
 
    Investment Valuation and Income Recognition
The fair value of investments held by the Plan has been determined by the trustee based on quoted market values of publicly traded investments.
 
    The investment contracts are presented at fair value on the statement of net assets available for benefits. The investments in the fully benefit-responsive investment contracts are also stated at contract value which is equal to principal balance plus accrued interest. As provided in the FSP, an investment contract is generally valued at contract value, rather than fair value, to the extent it is fully benefit-responsive. The fair value of fully benefit-responsive investment contracts is calculated using a discounted cash flow model which considers recent bids as determined by recognized dealers, discount rate and the duration of the underlying portfolio securities. The Plan’s investment in the Fidelity Managed Income Portfolio meets this definition.
 
    The Plan presents in the statements of changes in net assets available for benefits, the net appreciation in fair value of investments which consists of realized gains or losses and the unrealized appreciation (depreciation) on those investments. All investment transactions are recorded by the Plan as of the trade date. Gains or losses on sale of investments are determined by the specific identification method. Interest income is recorded as earned on an accrual basis. Dividends are recorded based on the ex-dividend date.
 
    Participant Loans
Participant Loans are recorded at cost, which approximates fair value.
 
    Administrative Expenses
All costs incurred in administering the Plan are paid by the Company except for certain broker fees that are paid out of the various investment options.

    2006     2005

   $ 5,604,607     $ 7,839,146  
 
            
 
4.   Tax Status
 
    The Plan is an adoption of the standardized prototype plan written by Fidelity Management & Research Company. The prototype sponsor received a favorable determination letter dated December 5, 2001 in which the Internal Revenue Service stated that the prototype plan, as then designated, was in compliance with applicable requirements of the Internal Revenue Code (the “IRC”). The prototype plan underwent an amendment during 2002 and the Internal Revenue Service issued a favorable determination letter dated October 9, 2003 in which the Internal Revenue Service stated that the amendment did not in and of itself adversely affect the Plan’s acceptability under the applicable sections of the IRC. Therefore, the Plan Administrator believes that the Plan was qualified and the related trust was tax exempt as of the financial statement dates. Accordingly, no provision for federal income taxes has been made.
 
5.   Distributions Payable
 
    Distributions payable pertain to participant pre-tax contributions which exceed the maximum annual dollar limit as established by the IRC. During the years ended December 31, 2006 and 2005, the Plan had a liability for excess contributions of $2,814 and $18,105, respectively. Such amounts have been refunded to the participants within the stipulated twelve month period, in order to bring the Plan into compliance with the IRC.

6.   Party-in-Interest Transactions
 
    Certain of the Plan’s investments are shares of mutual funds managed by Fidelity. Fidelity is the trustee as defined in the Plan and, therefore, these transactions qualify as party-in-interest. Participants’ loans are granted and administered by Fidelity and, therefore, these loan transactions qualify as party-in-interest. The Pediatrix Stock Fund invests in the Company’s common stock and, therefore, these investment transactions qualify as party-in-interest. All fees and expenses of the Plan for legal, accounting, recordkeeping and other administrative services are paid by the Company.
