KING OF PRUSSIA, PA – Universal Health Services, Inc. (NYSE: UHS) announced today that its reported net income attributable to UHS was $135.5 million, or $1.39 per diluted share, during the fourth quarter of 2012 as compared to $95.3 million, or $.98 per diluted share, during the comparable quarter of 2011.

Consolidated Results of Operations, As Adjusted – Three-month periods ended December 31, 2012 and 2011:

For the three-month period ended December 31, 2012, our adjusted net income attributable to UHS, as calculated on the attached Schedule of Non-GAAP Supplemental Consolidated Statements of Income Information (“Supplemental Schedule”), was $98.0 million, or $1.00 per diluted share, as compared to $88.8 million, or $.91 per diluted share, during the fourth quarter of 2011.

As reflected on the Supplemental Schedule, included in our reported results during the fourth quarter of 2012, was an aggregate net favorable after-tax impact of $37.4 million, or $.39 per diluted share, consisting of: (i) a favorable after-tax impact of approximately $15.5 million, or $.16 per diluted share, resulting from a reduction to our professional and general liability self-insurance reserves relating to years prior to 2012, based upon a reserve analysis; (ii) a favorable after-tax impact of approximately $16.4 million, or $.17 per diluted share, resulting from the gain realized on the sale of Auburn Regional Medical Center which was divested in October, 2012, and; (iii) a favorable after-tax impact of approximately $5.5 million, or $.06 per diluted share, related to the incentive income and expenses recorded in connection with the implementation of electronic health records (“EHR”) applications at our acute care hospitals (as discussed below in Accounting for HITECH Act incentive income and EHR expenses).

As reflected on the attached Supplemental Schedule, included in our net income attributable to UHS during the three-month period ended December 31, 2011, was the favorable after-tax impact of $6.5 million, or $.07 per diluted share, resulting from a reduction to our professional and general liability self-insurance reserves relating to years prior to 2011, based upon a reserve analysis.

As indicated on the attached Supplemental Schedule, included in our net income attributable to UHS during the year ended December 31, 2011, was the favorable after-tax impact of $6.5 million, or $.07 per diluted share, resulting from a reduction to our professional and general liability self-insurance reserves relating to years prior to 2011.

Acute Care Services – Three and twelve-month periods ended December 31, 2012 and 2011:

During the fourth quarter of 2012, at our acute care hospitals owned during both periods (“same facility basis”), adjusted admissions (adjusted for outpatient activity) increased 1.7% and adjusted patient days increased 1.4%, as compared to the fourth quarter of 2011. Net revenues at these facilities increased 3.1% during the fourth quarter of 2012 as compared to the comparable quarter of the prior year. At these facilities, net revenue per adjusted admission increased 1.4% while net revenue per adjusted patient day increased 1.7% during the fourth quarter of 2012 as compared to the comparable quarter of the prior year. On a same facility basis, the operating margin at our acute care hospitals decreased to 14.4% during the fourth quarter of 2012 as compared to 15.5% during the fourth quarter of 2011. We define operating margin as net revenues less salaries, wages and benefits, other operating expenses and supplies expense (excluding the impact of the items mentioned above and excluding the EHR impact, as indicated on the Supplemental Schedule).

During the twelve-months ended December 31, 2012, at our acute care hospitals on a same facility basis, adjusted admissions increased 0.2% and adjusted patient days increased 0.5%, as compared to the comparable twelve-month period of 2011. Net revenues at these facilities increased 0.4% during the full year of 2012 as compared to 2011. At these facilities, net revenue per adjusted admission increased 0.2% while net revenue per adjusted patient day decreased 0.1% during the twelve month period of 2012, as compared to 2011. The operating margin at our acute care hospitals owned during both years decreased to 15.8% during 2012, as compared to 17.2% during 2011.

We provide care to patients who meet certain financial or economic criteria without charge or at amounts substantially less than our established rates. Because we do not pursue collection of amounts determined to qualify as charity care, they are not reported in net revenues or in accounts receivable, net. Our acute care hospitals provided charity care and uninsured discounts, based on charges at established rates, amounting to $206 million and $248 million during the three-month periods ended December 31, 2012 and 2011, respectively, and $1.05 billion and $956 million during the twelve-month periods ended December 31, 2012 and 2011, respectively.

Behavioral Health Care Services – Three and twelve-month periods ended December 31, 2012 and 2011:

During the fourth quarter of 2012, at our behavioral health care facilities on a same facility basis, adjusted admissions increased 5.0% while adjusted patient days increased 0.5%, as compared to the fourth quarter of 2011. Net revenues at these facilities increased 4.5% during the fourth quarter of 2012, as compared to the comparable quarter in 2011. At these facilities, net revenue per adjusted admission decreased 0.5% while net revenue per adjusted patient day increased 4.0% during the fourth quarter of 2012 over the comparable quarter in 2011. The operating margin at our behavioral health care facilities owned during both periods increased to 27.6% during the fourth quarter of 2012, as compared to 25.3% during the fourth quarter of 2011.

During the twelve-months ended December 31, 2012, at our behavioral health care facilities on a same facility basis, adjusted admissions increased 5.0% while adjusted patient days increased 1.0%, as compared to the full year of 2011. Net revenues at these facilities increased 4.3% during the twelve-months of 2012, as compared to the comparable twelve-month period of 2011. At these facilities, net revenue per adjusted admission decreased 0.7% while net revenue per adjusted patient day increased 3.2% during the full year of 2012 over 2011. The operating margin at our behavioral health care facilities owned during both years increased to 27.7% during 2012 as compared to 26.3% during 2011.

Accounting for HITECH Act incentive income and EHR expenses:

The health information technology provisions of the American Recovery and Reinvestment Act (referred to as the “HITECH Act”) established criteria related to the “meaningful use” of electronic health records (“EHR”) for acute care hospitals and established requirements for the Medicare and Medicaid EHR payment incentive programs.

During 2011, we began implementing EHR applications at certain of our acute care hospitals and will continue to do so, on a hospital-by-hospital basis, until completion which is scheduled to occur by the end of June, 2013. As of December 31, 2012, EHR applications have been implemented at fourteen of our acute care hospitals. Our acute care hospitals are eligible for Medicare and Medicaid EHR incentive payments upon implementation of the EHR application, assuming they meet the “meaningful use” criteria. As of December 31, 2012, eleven hospitals met the “meaningful use” criteria.

As reflected on the Supplemental Schedule, our consolidated results of operations for the three-month period ended December 31, 2012 includes the favorable after-tax impact of approximately $5.5 million, or $.06 per diluted share, recorded in connection with the implementation of EHR applications. This favorable impact, which on a pre-tax basis amounted to $8.9 million, consists of $17.5 million of EHR incentive income offset by $3.4 million of salaries, wages, benefits and other operating expenses and $5.2 million of depreciation and amortization expense.

As reflected on the Supplemental Schedule, our consolidated results of operations for the year ended December 31, 2012 includes the favorable after-tax impact of approximately $1.9 million, or $.02 per diluted share, recorded in connection with the implementation of EHR applications. This favorable impact, which on a pre-tax basis amounted to $3.0 million, including a $700,000 benefit from the net expense attributable to third-party, non-controlling ownership interests, consists of $30.0 million of EHR incentive income offset by $14.4 million of salaries, wages, benefits and other operating expenses and $13.3 million of depreciation and amortization expense.

During 2013, based upon our remaining scheduled EHR implementations and anticipated “meaningful use” qualifications, we expect to record approximately $57 million of EHR incentive income and approximately $36 million of EHR-related incremental expenses (including $29 million of depreciation and amortization expense) resulting in a net favorable after-tax impact of approximately $13 million, or $.13 per diluted share.

2013 Full Year Guidance:

Excluding the favorable $.13 per diluted share EHR impact mentioned above, our estimated range of net income attributable to UHS for the year ended December 31, 2013, is $4.35 to $4.50 per diluted share. This guidance range represents an increase of approximately 5% to 8% over the adjusted net income attributable to UHS of $4.15 per diluted share for the year ended December 31, 2012, as calculated on the attached supplemental schedule, and as discussed above.

During 2013, our net revenues are estimated to increase approximately 6% to $7.41 billion, as compared to $6.96 billion during 2012.

This guidance range excludes the impact of items, if applicable, that are nonrecurring or non-operational in nature including items such as, but not limited to, gains on sales of assets and businesses, reserves for settlements, legal judgments and lawsuits and other material amounts that may be reflected in our financial statements that relate to prior periods. It is also subject to certain conditions including those as set forth below in General Information, Forward-Looking Statements and Risk Factors and Non-GAAP Financial Measures.

Acquisition of Ascend Health Corporation:

As previously announced, we completed the acquisition of Ascend Health Corporation (“Ascend”) in October, 2012. Ascend was the largest private behavioral health provider with 9 owned or leased freestanding inpatient facilities located in 5 states including Texas, Arizona, Utah, Oregon and Washington.

General Information, Forward-Looking Statements and Risk Factors and Non-GAAP Financial Measures:

Universal Health Services, Inc. (“UHS”) is one of the nation’s largest hospital companies, operating acute care and behavioral health hospitals and ambulatory centers nationwide and in Puerto Rico and the U.S. Virgin Islands. It acts as the advisor to Universal Health Realty Income Trust, a real estate investment trust (NYSE:UHT). For additional information on the Company, visit our web site: http://www.uhsinc.com.

This press release contains forward-looking statements based on current management expectations. Numerous factors, including those disclosed herein, those related to healthcare industry trends and those detailed in our filings with the Securities and Exchange Commission (as set forth in Item 1A-Risk Factors and in Item 7-Forward-Looking Statements and Risk Factors in our Form 10-K for the year ended December 31, 2012), may cause the results to differ materially from those anticipated in the forward-looking statements. The operating pressures that we continue to experience in many of our acute care markets has increased the volatility of our financial results making estimation of future results more challenging. Many of the factors that will determine our future results are beyond our capability to

control or predict. These statements are subject to risks and uncertainties and therefore actual results may differ materially. Readers should not place undue reliance on such forward-looking statements which reflect management’s view only as of the date hereof. We undertake no obligation to revise or update any forward-looking statements, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.

During the first quarter of 2012, we adopted the Financial Accounting Standards Board’s Accounting Standards Update No. 2011-07, “Health Care Entities (Topic 954): Presentation and Disclosure of Patient Service Revenue, Provision for Bad Debts, and the Allowance for Doubtful Accounts for Certain Health Care Entities,” which required health care entities to change the presentation in their statement of operations by reclassifying the provision for bad debts associated with patient service revenue from an operating expense to a deduction from patient service revenue (net of contractual allowances and discounts). As a result, the provision for doubtful accounts for our acute care and behavioral health care facilities is reflected as a deduction for net revenues in the accompanying consolidated statements of income for the three and twelve-month periods ended December 31, 2012 and 2011. The adoption of this standard had no impact on our financial position or results of operations.

As mentioned above, our acute care hospitals may qualify for EHR incentive payments upon implementation of an EHR application assuming they meet the “meaningful use” criteria. However, there can be no assurance that we (our acute care hospitals) will ultimately qualify for these incentive payments and, should we qualify, we are unable to quantify the amount of incentive payments we may receive since the amounts are dependent upon various factors including the implementation timing at each hospital. Should we qualify for incentive payments, there may be timing differences in the recognition of the incentive income and expenses recorded in connection with the implementation of the EHR application which may cause material period-to-period changes in our future results of operations. Hospitals that do not qualify as a meaningful user of EHR by 2015 are subject to a reduced market basket update to the inpatient prospective payment system standardized amount in 2015 and each subsequent fiscal year. Although we believe that our acute care hospitals will be in compliance with the EHR standards by 2015, there can be no assurance that all of our facilities will be in compliance and therefore not subject to the penalty provision of the HITECH Act.

We believe that operating income, operating margin, adjusted net income attributable to UHS, adjusted net income attributable to UHS per diluted share and earnings before interest, taxes, depreciation and amortization (“EBITDA”), which are non-GAAP financial measures (“GAAP” is Generally Accepted Accounting Principles in the United States of America), are helpful to our investors as measures of our operating performance. In addition, we believe that, when applicable, comparing and discussing our financial results based on these measures, as calculated, is helpful to our investors since it neutralizes the effect in each year of items that are nonrecurring or non-operational in nature including items such as, but not limited to, costs related to extinguishment of debt, gains on sales of assets and businesses, reserves for settlements, legal judgments and lawsuits and other amounts that may be reflected in the current or prior year financial statements that relate to prior periods. To obtain a complete understanding of our financial performance these measures should be examined in connection with net income, determined in accordance with GAAP, as presented in the condensed consolidated financial statements and notes thereto in this report or in our other filings with the Securities and Exchange Commission including our Report on Form 10-K for the year ended December 31, 2012. Since the items included or excluded from these measures are significant components in understanding

and assessing financial performance under GAAP, these measures should not be considered to be alternatives to net income as a measure of our operating performance or profitability. Since these measures, as presented, are not determined in accordance with GAAP and are thus susceptible to varying calculations, they may not be comparable to other similarly titled measures of other companies. Investors are encouraged to use GAAP measures when evaluating our financial performance.
