North Hollywood, CA — October 27, 2010 — IPC The Hospitalist Company, Inc. (NASDAQ: IPCM), a leading national hospitalist physician group practice, today announced record financial results for the third quarter ended September 30, 2010.

Third Quarter 2010 Highlights (comparisons are to third quarter 2009):

• Net revenue increased 17% to $90.9 million, with same-market area patient net revenue growth of 15%

• Patient encounters increased 16% to 957,000

• Income from operations rose 27% to $9.4 million

• Operating margin improved 80 basis points to 10.4%

• Net income increased 31% to $6.1 million, or $0.37 per diluted share

Nine Months Ended September 30, 2010 Highlights (comparisons are to nine months ended September 30, 2009):

• Net revenue increased 17% to $266.2 million, with same-market area patient net revenue growth of 13%

• Patient encounters increased 15% to 2,804,000

• Income from operations rose 26% to $27.8 million

• Operating margin improved 80 basis points to 10.4%

• Net income increased 30% to $17.2 million, or $1.04 per diluted share

Adam D. Singer, M.D., Chief Executive Officer of IPC The Hospitalist Company, stated, “In the third quarter, IPC continued to generate strong top-line revenue growth, delivering a record quarter with $90.9 million in revenues. At the same time, we also increased the profitability of the company with an 80 basis point improvement in operating margin.”

Dr. Singer added, “Our results are indicative of our sound strategy to grow the company through a combination of same market hires and practice acquisitions. We have closed ten acquisitions to date this year, including one acquisition that expanded our operations into a new geographical market. Our industry remains very fragmented. We have a full acquisition pipeline and will continue to pursue opportunities that fit with our growth strategy.”

Third Quarter 2010

Patient encounters for the three months ended September 30, 2010 increased 16.3% to 957,000, compared to 823,000 for the same period last year. Net revenue for the three months ended September 30, 2010 was $90.9 million, an increase of $13.4 million, or 17.3%, from $77.5 million for the three months ended September 30, 2009. Of this $13.4 million increase, $9.7 million, or 72.4%, was attributable to same-market area growth and $3.7 million, or 27.6%, was attributable to revenue generated from three new markets, two of which were entered through acquisitions in 2009 and one in 2010. Same-market encounters increased 13.0% and patient revenue per encounter increased 1.7% resulting in an increase in same-market patient revenue of 14.9%. Same-market hospital contract and other revenue decreased on a net basis primarily from less locum cost reimbursement, resulting in an overall 12.8% increase in same market net revenue.

Physician practice salaries, benefits and other expenses for the three months ended September 30, 2010 were $66.1 million, or 72.7% of net revenue, compared to $56.8 million, or 73.2% of net revenue, for the three months ended September 30, 2009.

General and administrative expenses were $14.7 million, or 16.2% of net revenue, for the three months ended September 30, 2010, as compared to $12.8 million, or 16.5% of net revenue, for the three months ended September 30, 2009.

Income from operations increased $2.0 million, or 27.1%, to $9.4 million, as compared to $7.4 million for the same period in the prior year. The operating margin increased to 10.4% for the three months ended September 30, 2010, up 80 basis points from an operating margin of 9.6% for the three months ended September 30, 2009.

The effective tax rate for the three months ended September 30, 2010 was 35.7% compared to 37.8% for the three months ended September 30, 2009. The decrease in the effective tax rate reflects a reduction in the Company’s tax liability for uncertain tax positions resulting from the lapse of statute of limitations and a reduction in its effective state tax rate.

Net income increased to $6.1 million for the three months ended September 30, 2010, as compared to $4.6 million for the three months ended September 30, 2009 and net income margin increased to 6.7% from 6.0% for the same period in the prior year. Earnings per diluted share for the third quarter of 2010 was $0.37, compared to earnings per diluted share of $0.28 for the third quarter of 2009, an increase of 31.8%.

Nine Months Ended September 30, 2010

Patient encounters for the nine months ended September 30, 2010 increased 15.4% to 2,804,000, compared to 2,429,000 for the same period last year. Net revenue for the nine months ended September 30, 2010 was $266.2 million, an increase of $37.8 million, or 16.6%, from $228.4 million for the nine months ended September 30, 2009. Of this $37.8 million increase, $26.2 million, or 69.3%, was attributable to same-market area growth and $11.6 million, or 30.7%, was attributable to revenue generated from three new markets, two of which were entered through acquisitions in 2009 and one in 2010. Same-market encounters increased 11.3% and patient revenue per encounter increased 1.6% resulting in an increase in same-market patient revenue of 13.1%. Same-market hospital contract and other revenue decreased on a net basis primarily from less locum cost reimbursement, resulting in an overall 11.5% increase in same-market net revenue.

Physician practice salaries, benefits and other expenses for the nine months ended September 30, 2010 were $192.8 million, or 72.4% of net revenue, compared to $166.7 million, or 73.0% of net revenue, for the nine months ended September 30, 2009.

General and administrative expenses were $43.7 million, or 16.4% of net revenue, for the nine months ended September 30, 2010, as compared to $37.9 million, or 16.6% of net revenue, for the nine months ended September 30, 2009.

Income from operations increased $5.8 million, or 26.2%, to $27.8 million, as compared to $22.0 million for the same period in the prior year. The operating margin increased to 10.4% for the nine months ended September 30, 2010, up 80 basis points from an operating margin of 9.6% for the nine months ended September 30, 2009.

The effective tax rate for the nine months ended September 30, 2010 was 37.9% compared to 39.2% for the nine months ended September 30, 2009. The decrease in the effective tax rate reflects a reduction in the Company’s tax liability for uncertain tax positions resulting from the lapse of statute of limitations and a reduction in its effective state tax rate. Without regard to tax legislation that may be passed in 2010, we expect our 2010 annual effective tax rate to be 38.1%.

Net income increased to $17.2 million for the nine months ended September 30, 2010, as compared to $13.3 million for the nine months ended September 30, 2009 and net income margin increased to 6.5% from 5.8% for the same period in the prior year. Earnings per diluted share for the nine month period ended September 30, 2010 was $1.04, compared to earnings per diluted share of $0.81 for the same period last year, an increase of 28.4%.

Liquidity and Capital Resources

As of September 30, 2010, the Company had approximately $79.1 million in liquidity, comprised of $49.2 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 the nine months ended September 30, 2010 was $31.8 million, compared to $24.2 million for the same period of 2009. Days sales outstanding (DSO) decreased to 49.1 DSO as of September 30, 2010, compared to 54.1 DSO as of December 31, 2009. During the first nine months of 2010, $13.8 million was used for the acquisition of physician practices and for earn-out payments on prior acquisitions, compared to $14.4 million in the same period of the prior year.

2010 Guidance Update

The Company has updated the range of its guidance for the full year 2010 and expects revenue to be in the range of $357 million to $361 million and earnings per diluted share to be in the range of $1.39 to $1.43. This compares to previous expectations for revenue in the range of $352 million to $361 million and earnings per diluted share in the range of $1.34 to $1.43. The Company has provided this outlook based on the following assumptions: (i) weighted average shares outstanding of 16.6 million for the year; (ii) a 38.1% effective tax rate, and (iii) Congress passing legislation to prevent the scheduled December 1, 2010 reduction in the Medicare Physician Fee Schedule. Not included in the assumptions are (i) practice acquisitions completed after today’s date, and (ii) future gains or losses related to changes in estimates of earn-outs attributable to practice acquisitions that closed subsequent to December 31, 2008.
