IPC The Hospitalist Company Reports Second Quarter 2011 Results

North Hollywood, CA—July 28, 2011—IPC The Hospitalist Company, Inc. (NASDAQ: IPCM), a leading national hospitalist physician group practice, today announced financial results for the second quarter ended June 30, 2011.

Second Quarter 2011 Highlights (comparisons are to second quarter 2010):

Six Months Ended June 30, 2011 Highlights (comparisons are to six months ended June 30, 2010):

Adam D. Singer, M.D., Chief Executive Officer of IPC The Hospitalist Company, stated, “We are very pleased to again report a strong revenue quarter with growth of 28%. This growth reflects not only the results of the acquisitions we completed in the latter part of 2010 through the second quarter of 2011, but also continued strength in our existing markets.

“However, our profitability this quarter was impacted by higher expenses at several of our larger hospital contracted practices. The added costs, which included higher compensation for locum tenens, moonlighters and premium call pay and discretionary bonuses for our employed physicians at those practices, led to a 130-basis-point increase in our practice operating expense as a percentage of revenue. In all cases, we are in the process of recruiting permanent staff and expect that these practices will generate improved practice margins over time.

“We continued to leverage our general and administrative costs which resulted in a 50-basis-point reduction in these costs as a percentage of revenue, partially offsetting the higher practice expenses. We generated a 9.4% operating margin for the quarter.”

Dr. Singer added, “We continue to execute on our strategy of organic hiring and acquisition growth. We have completed seven acquisitions year to date in 2011, which includes the recent acquisition in Orlando which gives us entry into a new market in our already strong Florida region. Our acquisition pipeline is robust, with a significant number of privately-owned, unaffiliated physician practices in both the acute and post-acute areas. In addition, we believe that there will continue to be more opportunities to add to our practices through hospital contracting, by either taking over employed groups or starting new groups under hospital contracts. However, the hospital contracted practices may impact our margins as we convert them from inefficient staffing models. We are confident in our ability to continue to execute our multi-pronged growth plan for the remainder of 2011 and beyond.”

Second Quarter 2011

Patient encounters for the three months ended June 30, 2011 increased by 239,000 encounters, or 26.0%, to 1,159,000, compared to 920,000 for the same period in the prior year. Net revenue for the three months ended June 30, 2011 was $111.7 million, an increase of $24.1 million, or 27.5%, from $87.6 million for the three months ended June 30, 2010. Of this $24.1 million increase, 71.4% was attributable to same-market area growth, including acquisitions and new hires, and 28.6% was attributable to revenue generated from four new markets, three of which were entered through acquisitions in 2010 and one in 2011. Same-market revenue increased 19.6%, same-market encounters increased 18.5% and patient revenue per encounter increased 0.5%. The remaining increase in same-market revenue was attributable to an increase in hospital contract and other revenue.

Physician practice salaries, benefits and other expenses for the three months ended June 30, 2011 were $81.8 million, or 73.2% of net revenue, compared to $63.1 million, or 71.9% of net revenue, for the three months ended June 30, 2010. The increase in practice costs is largely related to the increase in the number of hospitalists added through hiring and acquisitions during the period and to continued investment in physician leadership initiatives. As a percentage of revenue, physician costs increased by 130 basis points quarter over quarter. This increase in costs was largely the result of added cost for locum tenens, moonlighters and premium call pay and discretionary bonuses for employed physicians at several of the larger hospital contracted practices. In all cases, the Company is in the process of recruiting additional full-time staff in order to operate more efficiently.

General and administrative expenses increased $3.5 million, or 23.6%, to $18.4 million, or 16.5% of net revenue, for the three months ended June 30, 2011, as compared to $14.9 million, or 17.0% of net revenue, for the three months ended June 30, 2010. The increase in expense is primarily the result of increased costs to support the continuing growth of operations, including new regional office costs and increases in corporate development and other expenses to support acquisitions. In addition, stock based compensation expense increased primarily as a result of the increase in IPC’s stock price at the date of various grants. Excluding stock based compensation, general and administrative expenses decreased by 70 basis points to 15.4% of revenue, compared to 16.1% of revenue for the same period of 2010.

Income from operations increased $1.6 million, or 18.3%, to $10.5 million, as compared to $8.9 million for the same period in the prior year. The operating margin was 9.4% for the three months ended June 30, 2011, as compared to 10.2% for the three months ended June 30, 2010. The decrease in the operating margin was largely the result of the increase in physician costs as a percentage of revenue, offset by the decrease in general and administrative expenses as a percentage of revenue.

The effective tax rate for the three months ended June 30, 2011 was 38.0%, compared to 39.0% for the three months ended June 30, 2010.

Net income increased to $6.5 million for the three months ended June 30, 2011, as compared to $5.4 million for the three months ended June 30, 2010, and the net income margin was 5.8%, as compared to 6.2% for the same period in the prior year. Diluted earnings per share for the quarter ended June 30, 2011 was $0.39, compared to diluted earnings per share of $0.33 in the same quarter of 2010, an increase of 18.2%.

Six Months Ended June 30, 2011

Patient encounters for the six months ended June 30, 2011 increased by 498,000 encounters, or 27.0%, to 2,345,000, compared to 1,847,000 for the same period in the prior year. Net revenue for the six months ended June 30, 2011 was $225.1 million, an increase of $49.8 million, or 28.4%, from $175.3 million for the six months ended June 30, 2010. Of this $49.8 million increase, 73.9% was attributable to same-market area growth, including acquisitions and new hires, and 26.1% was attributable to revenue generated from four new markets, three of which were entered through acquisition in 2010 and one in 2011. Same-market revenue increased 21.0%, same-market encounters increased 19.8% and patient revenue per encounter increased 0.8%. The remaining increase in same-market revenue was attributable to an increase in hospital contract and other revenue.

Physician practice salaries, benefits and other expenses for the six months ended June 30, 2011 were $163.9 million, or 72.8% of net revenue, compared to $126.7 million, or 72.3% of net revenue, for the six months ended June 30, 2010. The increase in practice costs is largely related to the increase in the number of hospitalists added through hiring and acquisitions during the period and to continued investment in physician leadership initiatives.

General and administrative expenses increased $7.3 million, or 25.3%, to $36.2 million, or 16.1% of net revenue, for the six months ended June 30, 2011, as compared to $28.9 million, or 16.4% of net revenue, for the six months ended June 30, 2010. The increase in expense is primarily the result of increased costs to support the continuing growth of operations, including new regional office costs and increases in corporate development and other expenses to support acquisitions. In addition, stock based compensation expense increased primarily as a result of the increase in IPC’s stock price at the date of various grants. Excluding stock based compensation, general and administrative expenses decreased by 50 basis points to 15.1% of revenue, compared to 15.6% of revenue for the same period of 2010.

Income from operations increased $4.7 million, or 25.4%, to $23.0 million, as compared to $18.3 million for the same period in the prior year. The operating margin was 10.2% for the six months ended June 30, 2011, compared to 10.5% for the six months ended June 30, 2010. The decrease in the operating margin was largely the result of the increase in physician costs as a percentage of revenue, offset by the decrease in general and administrative expenses as a percentage of revenue.

The effective tax rate for the six months ended June 30, 2011 was 38.0%, compared to 39.0% for the six months ended June 30, 2010.

Net income increased to $14.2 million for the six months ended June 30, 2011, as compared to $11.2 million for the six months ended June 30, 2010, and the net income margin was 6.3%, as compared to 6.4% for the same period in the prior year. Diluted earnings per share for the six months ended June 30, 2011 was $0.85, compared to diluted earnings per share of $0.67 in the same period of 2010, an increase of 26.9%.

Liquidity and Capital Resources

As of June 30, 2011, IPC had no debt outstanding, and approximately $54.6 million in liquidity, composed of $24.7 million in cash and cash equivalents, and an available line of credit of $29.9 million.

Net cash provided by operating activities for the six months ended June 30, 2011 was $12.0 million, compared to $15.1 million for the same period of 2010. The decrease in net cash from operations between the two periods is largely the result of an increase in accounts receivable and a decrease in accrued compensation caused by the timing of payrolls. Although accounts receivables increased since December 31, 2010, the days sales outstanding (DSO), which is used to measure the effectiveness of collections, decreased to 49 DSO as of June 30, 2011, compared to 51 DSO as of December 31, 2010.

Net cash used in investing activities was $9.2 million for the six months ended June 30, 2011, compared to $13.4 million for the same period in 2010. Cash of $7.7 million was used in 2011 for physician practice acquisitions and earn-out payments on prior acquisitions compared to $12.2 million in the same period of the prior year.

2011 Guidance

The Company is updating its 2011 guidance from the numbers announced in February to reflect the results of the first half of the year. For the full year 2011, the Company is increasing the revenue range to $452 million to $460 million from the previous range of $446 million to $455 million. The Company is maintaining the range for earnings per diluted share to be between $1.78 and $1.86.
