UNITED SURGICAL PARTNERS INTERNATIONAL ANNOUNCES SECOND
QUARTER 2011 RESULTS

Dallas, Texas (August 2, 2011) — United Surgical Partners International, Inc. (“USPI” or the “Company”) today announced results for the second quarter and six months ended June 30, 2011.

Second Quarter Financial Results

     For the quarter ended June 30, 2011, consolidated net revenues increased 6% to $151.1 million compared with $143.2 million in the prior year period. Operating income increased 9% for the second quarter and was $62.5 million as compared with $57.6 million for the prior year period. Operating income was benefited by $2.0 million due to gains on the sale of facilities. Operating income margin for the second quarter increased 120 basis points to 41.4% versus 40.2% in the prior year period. For the quarter, EBITDA less noncontrolling interests was $50.8 million compared with $50.2 million in the prior year period.

     The financial results for the second quarter were driven by systemwide revenue growth of 12%, consisting of 6% U.S. same-facility revenue growth and the remainder being due to acquisition activity.

     Cash flows from operating activities for the second quarter totaled $31.1 million compared with $37.8 million for the prior year period. This decrease was due to an increase in the cash payment of taxes of $5.5 million. During the second quarter, the Company and its consolidated subsidiaries invested approximately $2.2 million in maintenance capital expenditures and an additional $4.1 million to develop new facilities and expand existing facilities.

Six-Month Financial Results

     For the six months ended June 30, 2011, consolidated net revenues increased 6% to $298.1 million compared with $281.1 million in the prior year period. Operating income increased 13% for the first half of 2011 to $121.5 million as compared with $107.9 million for the prior year period.

For the first half of 2011, EBITDA less noncontrolling interests increased 7% to $100.9 million compared with $94.6 million in the prior year period.

     Cash flows from operating activities for the six months ended June 30, 2011, totaled $72.7 million compared with $76.4 million for the prior year period. This decrease was due to an increase in the cash payment of taxes of $15.1 million.

Systemwide Financial Results

     Due to the Company’s partnerships with physicians and not-for-profit healthcare systems, the Company does not consolidate the financial results of the majority of its facilities. While revenues of the Company’s unconsolidated facilities are not recorded as revenues by USPI, equity in earnings of unconsolidated affiliates is a significant and growing portion of the Company’s overall earnings. To help analyze results of operations, management uses systemwide operating measures such as systemwide revenue growth, which includes revenues of both consolidated and unconsolidated facilities. In addition to overall systemwide revenue growth, USPI calculates growth rates and operating margins for the facilities that were operational in both the current and prior year periods, a group the Company refers to as same-store or same-facility. This group also consists of both consolidated and unconsolidated facilities. At June 30, 2011, 132 of the 191 facilities the Company operated were not consolidated.

Revenue Analysis

     For the second quarter, the systemwide revenues of the facilities operated by the Company increased 12% on a year-over-year basis, while consolidated revenues increased 6%. For the first half of 2011, the systemwide revenues of the facilities operated by the Company increased 13% on a year-over-year basis, while consolidated revenues increased 6%. The table below lists the key drivers of year-over-year changes in revenues.
