FOR IMMEDIATE RELEASE

Mednax Reports First Quarter Results

FORT LAUDERDALE, Fla., May 7, 2021—Mednax, Inc. (NYSE: MD), the national medical group specializing in prenatal, neonatal, and pediatric services, today reported earnings from continuing operations of $0.06 per share for the three months ended March 31, 2021. On a non-GAAP basis, Mednax reported Adjusted EPS from continuing operations of $0.24.

For the 2021 first quarter, Mednax reported the following results from continuing operations:

“Our operating results for the first quarter of 2021 reflected a meaningful positive trend through the quarter of patient volumes and payor mix,” said Mark S. Ordan, Chief Executive Officer of Mednax. “We believe that along with this trend, our singular focus on supporting our affiliated clinicians and the incredible care they provide to women and children and our efforts to reshape our operating efficiency will enable us to grow and to drive strong results for all stakeholders.”

Operating Results from Continuing Operations – Three Months Ended March 31, 2021

During the 2021 first quarter, Mednax’s operations were negatively impacted by reductions in patient volumes and revenue from the COVID-19 pandemic. However, this impact was less significant than during the fourth quarter of 2020.

Mednax’s net revenue for the three months ended March 31, 2021 was $446.8 million, compared to $441.2 million for the prior-year period. Mednax’s overall same-unit revenue increased by 2.5 percent, slightly offset by net acquisition activity. After adjusting to exclude the leap-year impact of an extra day in the 2020 first quarter results, overall same-unit revenue increased 3.6 percent.

Same-unit revenue from net reimbursement-related factors increased by 5.0 percent for the 2021 first quarter as compared to the prior-year period. The net increase primarily reflects funds received under the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act; modest improvements in managed care contracting; increases in contract and administrative fees; and an approximately 110 basis point increase in the percentage of services reimbursed by commercial and other non-government payors. During the 2021 first quarter, the Company recorded $7.7 million of miscellaneous revenue from the provider relief fund established by the CARES Act, which increased the Company’s same-unit revenue from net reimbursement-related factors by 1.8 percent.

Same-unit revenue attributable to patient volume decreased by 2.5 percent for the 2021 first quarter as compared to the prior-year period, and as compared to a decrease of approximately 6.6 percent for the 2020 fourth quarter. In each case, this decline was primarily attributable to the impacts from the COVID-19 pandemic. After adjusting to exclude the leap-year impact of an extra day in the 2020 first quarter results, overall same-unit revenue attributable to patient volume decreased by 1.4 percent.

Shown below are year-over-year percentage changes in selected same-unit volume statistics for the quarter ended March 31, 2021.

For the 2021 first quarter, practice salaries and benefits expense was $319.0 million, compared to $316.3 million for the prior-year period. This increase primarily reflects increases in variable incentive compensation, based on practice-level revenue and other financial results during the quarter, partially offset by favorable malpractice expense year over year.

For the 2021 first quarter, general and administrative expenses were $66.5 million, as compared to $67.4 million for the prior-year period. This decrease reflects stock-based compensation and salary decreases from net staffing reductions, partially offset by approximately $5 million in expenses incurred as part of the Company’s transitional services being provided to the buyers of the Company’s former anesthesiology and radiology medical groups. Mednax was reimbursed for these transition services expenses and recorded such reimbursement within investment and other income, a component of net non-operating expenses.

For the first quarter of 2021, transformational and restructuring related expenses totaled $4.9 million, compared to $16.1 million for the first quarter of 2020. Of the expense recorded during the first quarter of 2021, $3.7 million related to third-party consulting fees, while the remainder related primarily to contract termination fees and position eliminations.

Adjusted EBITDA from continuing operations, which is defined as earnings from continuing operations before interest, loss on early extinguishment of debt, taxes, depreciation and amortization, and transformational and restructuring related expenses, was $45.5 million for the 2021 first quarter, compared to $33.1 million for the prior-year period. Funds received from the provider relief fund established by the CARES Act impacted Adjusted EBITDA positively by approximately $4 million for the 2021 first quarter.

Depreciation and amortization expense was $8.0 million for the first quarter of 2021 compared to $6.8 million for the first quarter of 2020.

Investment and other income was $6.0 million for the first quarter of 2021 compared to a loss of $1.0 million for the first quarter of 2020. This increase primarily represents the reimbursement related to the transition services being provided to the buyers of the Company’s former anesthesiology and radiology medical groups.

Interest expense was $17.6 million for the first quarter of 2021 compared to $27.7 million for the first quarter of 2020. This decline primarily reflects the Company’s January 7, 2021 redemption of its $750 million in outstanding principle amount of 5.25% senior notes due 2023 (the “2023 Notes”).

Loss on early extinguishment of debt, related to the redemption of the 2023 Notes, was $14.5 million for the first quarter of 2021, which included cash premiums and accelerated amortization of deferred financing costs.

Mednax generated income from continuing operations of $5.4 million, or $0.06 per diluted share, for the 2021 first quarter, based on a weighted average 85.5 million shares outstanding. This compares with a loss from continuing operations of $18.5 million, or $0.22 per diluted share, for the 2020 first quarter, based on a weighted average 82.8 million shares outstanding.

For the first quarter of 2021, Mednax reported Adjusted EPS from continuing operations of $0.24, compared to $0.06 for the first quarter of 2020. For these periods, Adjusted EPS from continuing operations is defined as diluted income from continuing operations per common and common equivalent share excluding non-cash amortization expense, stock-based compensation expense, transformational and restructuring related expenses, loss on early extinguishment of debt and discrete tax items.

Financial Position and Cash Flow – Continuing Operations

Mednax had cash and cash equivalents of $270 million at March 31, 2021, compared to $1.12 billion on December 31, 2020, and net accounts receivable were $246 million. Mednax used $764 million in cash in January 2021 to redeem its $750 million 2023 Notes, including cash premiums and accrued interest.

During the first quarter of 2021, Mednax used cash of $98.9 million to fund continuing operations, compared to a use of $153.0 million during the first quarter of 2020. Mednax typically uses cash during the first quarter of each year as it pays incentive compensation, principally to its affiliated physicians, and employee benefit plan matching contributions that were accrued during the prior year. Additionally, during the first quarter of 2021, the Company used $9.1 million to fund capital expenditures and $6.0 million to fund the acquisition of two physician groups.

At March 31, 2021, Mednax had no outstanding borrowings under its $1.2 billion revolving credit facility and had total debt outstanding of $1.0 billion, consisting solely of its senior notes due 2027, and net debt of $730 million.

Discontinued Operations

Discontinued operations for the three months ended March 31, 2021 reflects adjustments to the loss on sale related to the divestiture of the anesthesiology medical group. Discontinued operations for the three months ended March 31, 2020 includes the operating results of the Company’s former anesthesiology and radiology medical groups.
