IPC The Hospitalist Company Reports Record First Quarter 2009 Results

North Hollywood, CA—May 4, 2009—IPC The Hospitalist Company, Inc. (NASDAQ: IPCM), a leading national hospitalist physician group practice, today announced financial results for the first quarter ended March 31, 2009.

First Quarter 2009 Highlights (comparisons are to first quarter 2008):

• Net revenue increased 26% to $76.1 million, with same-market area net revenue growth of 19%

• Patient encounters increased 18% to 810,000

• Income from operations rose 39% to $7.6 million

• Operating margin improved 90 basis points to 9.9%

• Net income increased 50% to $4.5 million, or $0.28 per diluted share for the quarter

Adam D. Singer, M.D., Chief Executive Officer of IPC The Hospitalist Company, stated, “Our record results for the first quarter of 2009 reflect IPC’s continued ability to generate strong revenue growth and expand operating margin. The first quarter revenue growth of 26% was driven by increased penetration of same-market areas, as well as the contribution from IPC’s entry into its newest market in Southeast Florida. As we grow our revenue base, we have a significant opportunity to leverage our general and administrative costs, as evidenced by the 90 basis point improvement in our operating margin. We also continued to strengthen our balance sheet by increasing our cash flow and reducing our days sales outstanding, which resulted in an increase in our cash balance.”

Dr. Singer added, “In line with our growth strategy, we are aggressively continuing to recruit new physicians to add to our existing practices. In the first quarter, we also completed two in-market acquisitions in Phoenix, which strengthened our foothold in one of our largest markets. Our acquisition pipeline remains robust in this highly fragmented industry, and we continue to evaluate opportunities across the hospitalist sector. We remain confident that we can continue to grow and penetrate current and new markets through this combination of organic growth and acquisitions. With less than 5% of our encounters coming from elective in-patient stays and uninsured patients remaining stable at approximately 7% of our encounters, we believe we are very well positioned in this challenging economic environment.”

First Quarter 2009

IPC’s first quarter 2009 patient encounters rose 18% to 810,000, compared to 684,000 in the same period last year. Net revenue for the first quarter was $76.1 million, an increase of $15.5 million, or 25.6%, from $60.6 million for the prior year quarter. Of this $15.5 million increase, $11.8 million, or 76.1%, was attributable to same-market area growth and $3.7 million was attributable to revenue generated from a new market acquisition, which was completed in the third quarter of 2008. The change in same-market area net revenue was the result of an 11.9% increase in patient encounters, a 5.9% increase in patient revenue per encounter and an increase in hospital contract revenue. The increase in patient revenue per encounter was partially due to an increase in Medicare reimbursement rates for the billing codes applicable to the services performed by the Company’s hospitalists, as well as improvements in billing processes and collections.

Physician practice salaries, benefits and other expenses for the three months ended March 31, 2009 were $55.5 million, or 72.9%, of net revenue compared to $43.9 million, or 72.6%, of net revenue for the three months ended March 31, 2008. Physician costs as a percentage of net revenue increased slightly as a result of the costs associated with one hospital contract being operated at breakeven, as it is being staffed with locum tenens and other part-time providers at the hospital’s request while IPC recruits employed staff. Excluding this contract, physician costs as a percentage of net revenue for the current quarter were at the same level as the prior year quarter.

General and administrative expenses for the first quarter of 2009 were $12.4 million, compared to $10.7 million for the first quarter of 2008. General and administrative expenses as a percentage of net revenue declined to 16.4% for the first quarter of 2009, compared to 17.7% for the first quarter of 2008, as the Company continues to leverage these costs over a larger revenue base as it grows its existing practices and continues to acquire new practices.

Income from operations for the first quarter of 2009 increased 39.4% to $7.6 million, compared to $5.4 million for the first quarter of 2008. The Company’s operating margin rose to 9.9% for the first quarter of 2009, compared to 9.0% for the first quarter of 2008. The increase in operating margin was primarily the result of the reduction in general and administrative expenses as a percentage of net revenue.

The effective tax rate for the three months ended March 31, 2009 was 40.0%, compared to 42.0% for the three months ended March 31, 2008. The decrease in the effective tax rate reflected a new enterprise zone tax credit recorded for the first time in the fourth quarter of 2008. The Company expects its effective tax rate to remain at 40% for the remainder of 2009.

First quarter 2009 net income increased by 50% to $4.5 million, or $0.28 per diluted share, compared to $3.0 million, or $0.21 per pro-forma diluted share, for the first quarter of 2008.

Cash flow from operations for the first quarter of 2009 was $10.7 million, compared to $2.6 million for the same quarter of 2008. Days sales outstanding (DSO) decreased to 55 DSO at the end of the quarter, compared to 60 DSO as of December 31, 2008, as the Company continued to improve its billing processes and collections. During the quarter, the Company expended $4.8 million for physician practice acquisitions and earn-out payments attributable to practices acquired in 2007 and 2008.

Guidance

For the full year 2009, the Company continues to expect revenue to be in the range of $300 million to $305 million and earnings per diluted share to be in the range of $1.01 to $1.11. The Company has provided this outlook based on the following assumptions: (i) an estimated 4.6% increase in the weighted average reimbursement rates for services provided to Medicare patients; (ii) continued growth in same-market areas whether from new hires or in-market acquisitions; (iii) a 40% effective tax rate; and (iv) 16.3 million weighted average diluted shares outstanding for the year. Not included in the assumptions are (i) new market acquisitions; (ii) increased general and administrative expenses as a result of the requirement of FAS Statement 141(R) to expense external costs associated with acquisitions that close subsequent to December 31, 2008; and (iii) gains or losses related to changes in estimates of earn-outs related to acquisitions that close subsequent to December 31, 2008 as required by FAS Statement 141(R).
