IPC The Hospitalist Company Reports Record Fourth Quarter and Full Year 2010 Results

North Hollywood, CA—March 7, 2011—IPC The Hospitalist Company, Inc. (NASDAQ: IPCM), a leading national hospitalist physician group practice, today announced financial results for the fourth quarter and full year ended December 31, 2010.

Fourth Quarter 2010 Highlights (comparisons are to fourth quarter 2009):

Year Ended December 31, 2010 Highlights (comparisons are to the year ended December 31, 2009):

Adam D. Singer, M.D., Chief Executive Officer of IPC The Hospitalist Company, stated, “We are very pleased to report that we reached a new milestone for the fourth quarter with 1.0 million patient encounters generating $97.2 million in revenue, for an 18% increase. Our existing markets increased revenue by 14% and our five new markets, including two we entered in 2009 and three in 2010, contributed to the overall top-line growth. Acquisitions remain an important part of our growth strategy and we continue to execute on plan. We completed fifteen acquisitions in 2010, including eight in the fourth quarter. To-date in 2011 we have completed two more acquisitions and taken over two hospitalist groups previously employed by a hospital system.”

Dr. Singer added, “Included in our 2010 acquisitions were three physician groups specializing in post-acute facilities. Combined with our existing post-acute practices, we believe IPC is now one of the largest providers of hospitalist services in the post-acute arena. Expansion of our post-acute services is important to our growth strategy as it further solidifies our market presence and allows us to provide care coordination for in-patients across a wide spectrum of healthcare facilities including acute, long-term care, skilled nursing, rehabilitation and psychiatric facilities. In this era of healthcare reform, we believe the ability to provide coverage across the entire episode of facility based care positions us well.”

Fourth Quarter 2010

Patient encounters for the three months ended December 31, 2010 increased by 141,000, or 16.3%, to 1,006,000, compared to 865,000 for the same period last year. Net revenue for the three months ended December 31, 2010 was $97.2 million, an increase of $15.0 million, or 18.3%, from $82.2 million for the three months ended December 31, 2009. Of this $15.0 million increase, $11.5 million, or 76.7%, was attributable to same-market area growth and $3.5 million was attributable to revenue generated from new market acquisitions. IPC entered two new markets through acquisitions in 2009 and three new markets through acquisitions in 2010. The increase in same-market area net revenue of 14.4% was largely the result of a 13.3% increase in patient encounters.

Physician practice salaries, benefits and other expenses for the three months ended December 31, 2010 were $68.8 million, or 70.8% of net revenue, compared to $59.1 million, or 71.9% of net revenue, for the three months ended December 31, 2009. The increase in practice costs is largely related to the increase in the number of hospitalists added through hiring and acquisitions during the year.

General and administrative expenses increased $2.8 million, or 20.6%, to $16.2 million, or 16.6% of net revenue, for the three months ended December 31, 2010, as compared to $13.4 million, or 16.3% of net revenue, for the three months ended December 31, 2009. The increase in expense is the result of increased stock based compensation due to IPC’s higher stock price, the opening of several new regional offices to support the five new markets entered by acquisitions, additional corporate development, legal and compliance expense to support the higher level of acquisitions in 2010, and increased finance and information technology costs to support the continuing growth of operations. General and administrative expenses as a percentage of net revenue increased slightly in 2010 as compared to 2009, primarily as a result of the increase in stock based compensation. The increase in stock based compensation expense as a percentage of revenue increased the overall general and administrative percentage by 41 basis points in the fourth quarter of 2010 compared to the fourth quarter of 2009.

Income from operations increased $3.2 million, or 38.6%, to $11.5 million, as compared to $8.3 million for the same period in the prior year. The operating margin was 11.9% for the three months ended December 31, 2010, compared to 10.1% for the three months ended December 31, 2009. Included in income from operations in the fourth quarter of 2009 was a professional liability settlement in excess of third party insurance coverage in the amount of $750,000. Excluding this item, the operating margin improvement was 90 basis points.

The effective tax rate increased in the fourth quarter of 2010 to 39.0% as compared to 35.4% for the same period last year. The increase in the effective tax rate is primarily attributable to the recognition of increased benefits from certain revised state tax credits and deductions in the 2009 fourth quarter tax provision while the same level of tax credits and deductions were recognized over four quarters in 2010. The effective tax rate differs from the statutory U.S. federal rate of 35.0% due primarily to state income taxes.

Net income increased to $7.0 million for the three months ended December 31, 2010, as compared to $5.4 million for the three months ended December 31, 2009, and the net income margin increased to 7.2% from 6.5% for the same period in the prior year. Diluted earnings per share for the quarter ended December 31, 2010 was $0.42, compared to diluted earnings per share of $0.32 in the fourth quarter of 2009, an increase of 29.4%.

Year Ended December 31, 2010

Patient encounters for 2010 increased by 516,000, or 15.7%, to 3,810,000, compared to 3,294,000 for 2009. Net revenue for 2010 was $363.4 million, an increase of $52.9 million, or 17.0%, from $310.5 million for 2009. Of this $52.9 million increase, $37.7 million, or 71.3%, was attributable to same-market area growth and $15.2 million was attributable to revenue generated from five new markets, two of which were entered through acquisition in 2009 and three in 2010. Same-market encounters increased 11.8% and patient revenue per encounter increased 1.3%, resulting in an increase in same-market patient revenue of 13.3%. Same-market hospital contract and other revenue decreased on a net basis, primarily from less locum cost reimbursement, resulting in an overall 12.3% increase in same-market net revenue.

Physician practice salaries, benefits and other expenses for 2010 were $261.5 million, or 72.0% of net revenue, compared to $225.8 million, or 72.7% of net revenue for 2009. These costs increased by $35.7 million, or 15.8%. The increase in practice costs is largely related to the increase in the number of hospitalists added through hiring and acquisitions during the year.

General and administrative expenses increased $8.6 million, or 16.6%, to $59.9 million, or 16.5% of net revenue for 2010, as compared to $51.3 million, or 16.5% of net revenue for 2009. The increase in expense is primarily the result of increased stock based compensation due to IPC’s higher stock price, the opening of several new regional offices to support the five new markets entered by acquisitions, additional corporate development, legal and compliance staff to support the higher level of acquisitions in 2010, and increased finance and information technology costs to support the continuing growth of operations. The increase in stock based compensation expense as a percentage of revenue increased the overall general and administrative percentage by 34 basis points for 2010 compared to 2009.

Income from operations increased $9.0 million, or 29.6%, to $39.3 million, as compared to $30.3 million for 2009. The operating margin increased to 10.8% for 2010 compared to 9.8% for 2009. Included in income from operations in the fourth quarter of 2009 was a professional liability settlement in excess of third party insurance coverage in the amount of $750,000. Excluding this item, the operating margin improvement was 80 basis points.

The effective tax rate for the years ended December 31, 2010 and 2009 was 38.2%.

Net income increased to $24.3 million for 2010, as compared to $18.6 million for 2009, and the net income margin increased to 6.7% from 6.0% for the same period in the prior year. Diluted earnings per share for 2010 was $1.46, compared to diluted earnings per share of $1.14 for 2009, an increase of 28.1%.

As of December 31, 2010, IPC had approximately $48.8 million in liquidity, comprised of $18.9 million in cash and cash equivalents, no debt outstanding and an available line of credit of $29.9 million.

Net cash provided by operating activities for 2010 increased to $29.6 million compared to $23.5 million for 2009. Days sales outstanding (DSO) decreased to 51 DSO as of December 31, 2010, compared to 54 DSO as of December 31, 2009. During 2010, cash
