IPC The Hospitalist Company Reports Fourth Quarter and Full Year 2013 Financial Results

- Company Achieves Double-Digit Growth in Revenues, Adjusted Income From Operations, and Adjusted Earnings Per Share-

North Hollywood, CA—February 20, 2014—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, 2013. All operating results referred to as “adjusted” exclude the change in fair market value of contingent consideration (“net change in fair value”) for acquisitions. See “Reconciliation of Non-GAAP Financial Measures” below for explanations of these non-GAAP financial measures and reconciliation to GAAP financial measures.

Fourth Quarter 2013 Highlights (comparisons are to fourth quarter 2012):

Twelve Months Ended December 31, 2013 Highlights (comparisons are to twelve months ended December 31, 2012):

Adam D. Singer, M.D., Chief Executive Officer of IPC The Hospitalist Company, stated, “We are once again very pleased with our quarterly results with double digit growth in revenues, adjusted income from operations and adjusted net income. Our 18% growth in revenues was driven by a 24% net increase in the number of providers since December 2012. This impressive growth stems from organic hires and the acquisition of hospitalist practices in both the acute and post-acute settings.”

Dr. Singer added, “2013 was an unprecedented year, as we acquired 19 hospitalist practices, including a strategic acquisition of a large group of acute-care practices from a hospital system, and the entry into a new market in the New York metropolitan area through the acquisition of what we believe was the largest post-acute practice in the country. These accomplishments demonstrate the positive returns from the investments we have made in our M&A team.”

Fourth Quarter 2013

Patient encounters for the three months ended December 31, 2013 increased by 166,000, or 11.5%, to 1,613,000, compared with 1,447,000 for the same period in the prior year. Net revenue for the three months ended December 31, 2013 was $161.6 million, an increase of $24.0 million, or 17.5%, from $137.6 million for the same period in the prior year. Of this $24.0 million increase, 81% was attributable to same-market area growth, including tuck-in acquisitions and new hires, and 19% was attributable to revenue generated from operations in new markets. Same-market revenue increased 14.7%, same-market encounters increased 7.2%, and same market patient revenue per encounter increased 2.2%. The remaining increase in same-market revenue was attributable to an increase in hospital stipends, medical directorship revenues, and meaningful use incentives. The 2.2% increase is largely due to a combination of Medicare fee schedule rate increases and Medicaid parity, offset by the automatic cut in Medicare payments triggered by sequestration effective April 1, 2013. Meaningful use is the set of standards defined by the Centers for Medicare & Medicaid Services Incentive Programs that governs the use of electronic health records and allows eligible providers and hospitals to earn incentive payments by meeting specific criteria. Medicaid parity represents an increase in Medicaid payments up to Medicare reimbursement levels for 2013 and 2014 in accordance with the Patient Protection and Affordable Care Act of 2010, as amended.

Physician practice salaries, benefits and other expenses for the three months ended December 31, 2013 were $117.4 million, or 72.6% of net revenue, compared with $100.3 million, or 72.9 % of net revenue, for the same period in the prior year. The dollar increase in practice costs is largely related to the increase in the number of hospitalists added through hiring and acquisitions during the period.

General and administrative expenses increased $4.5 million, or 20.2%, to $27.0 million, or 16.7% of net revenue, for the three months ended December 31, 2013, compared with $22.5 million, or 16.3% of net revenue, for the three months ended December 31, 2012. The increase in expense is primarily the result of increased costs to support the continuing growth of operations and acquisitions, including new regional office costs, incremental cost of supporting the Company’s post-acute business, legal fees and other expenses. Excluding stock-based compensation, general and administrative expenses were 15.6% of net revenue for the three months ended December 31, 2013, compared with 15.2% of net revenue for the same period of 2012.

The net change in fair value of contingent consideration (“net change in fair value”) for acquisitions was a $340,000 increase to expense and a $187,000 reduction to expense for the three months ended December 31, 2013 and 2012, respectively.

Adjusted income from operations for the three months ended December 31, 2013 increased 16.2% to $16.0 million, or an adjusted operating margin of 9.9%, compared with adjusted income from operations of $13.8 million, or an adjusted operating margin of 10.0% for the same period in 2012. GAAP income from operations increased $1.7 million, or 12.2%, to $15.7 million from $14.0 million for the same period in the prior year. GAAP operating margin was 9.7% and 10.1% for the three months ended December 31, 2013 and 2012, respectively.

The effective tax rate for the three months ended December 31, 2013 was 38.3%, compared with 39.1% for the same period in the prior year. The decrease in the effective tax rate was primarily related to a change in state tax laws in November 2012. The cumulative effect of the change in state tax laws was recorded during the three months ended December 31, 2012.

Adjusted net income for the three months ended December 31, 2013 increased 16.8% to $9.7 million, or a 6.0% adjusted net income margin, compared with adjusted net income of $8.3 million, or a 6.1% adjusted net income margin, for the same period in 2012. GAAP net income for the three months ended December 31, 2013 increased to $9.5 million from $8.4 million for the three months ended December 31, 2012, and GAAP net income margin was 5.9% and 6.1% for the three months ended December 31, 2013 and 2012, respectively.

Adjusted diluted earnings per share for the three months ended December 31, 2013 increased 13.8% to $0.56, compared with $0.49 adjusted diluted earnings per share for the same period in 2012. GAAP diluted earnings per share for the three months ended December 31, 2013 was $0.54, compared with $0.50 for the same period in 2012.

Year Ended December 31, 2013

Patient encounters for 2013 increased by 715,000, or 13.0%, to 6,211,000, compared with 5,496,000 for 2012. Net revenue for 2013 was $609.5 million, an increase of $86.0 million, or 16.4%, from $523.5 million for 2012. Of this $86.0 million increase, 77% was attributable to same-market area growth, including tuck-in acquisitions and new hires, and 23% was attributable to revenue generated from operations in new markets. Same-market revenue increased 12.8%, same-market encounters increased 8.5% and same market patient revenue per encounter increased 1.8%. The remaining increase in same-market revenue was attributable to an increase in hospital stipends, medical directorship revenues, and meaningful use incentives. The 1.8% increase is largely due to a combination of Medicare fee schedule rate increases and Medicaid parity, offset by the automatic cut in Medicare payments triggered by sequestration effective April 1, 2013.

Physician practice salaries, benefits and other expenses for 2013 were $444.2 million, or 72.9% of net revenue, compared with $382.9 million or 73.2 % of net revenue, for 2012. The dollar increase in practice costs is largely related to the increase in the number of hospitalists added through hiring and acquisitions during the period.

General and administrative expenses increased $15.0 million, or 18.0%, to $98.7 million, or 16.2% of net revenue, for 2013, compared with $83.7 million, or 16.0% of net revenue, for 2012. The increase in expense is primarily the result of increased costs to support the continuing growth of operations and acquisitions, including new regional office costs, incremental cost of supporting the Company’s post-acute business, legal expenses and other expenses. Excluding stock-based compensation, general and administrative expenses were 15.0% of net revenue for 2013, compared with 14.8% of net revenue for 2012.

The net change in fair value was a $5.7 million reduction to expense and a $0.3 million increase to expense for 2013 and 2012, respectively. The $5.7 million reduction to expense was primarily associated with an acquisition in the behavioral health subspecialty. Though the acquisition has proven to be profitable and continues to grow, it is growing slower than original assumptions, resulting in a reduction of estimated contingent consideration payable and a reduction to expense. Because the fair value of contingent consideration is generally based on a certain multiple of operating results of the acquired practices during a measurement period, a moderate change in projected operating results can result in a large change to the fair value of such contingent consideration.

Adjusted income from operations for 2013 increased 16.9% to $61.9 million, or an adjusted operating margin of 10.2%, compared with adjusted income from operations of $53.0 million, or an adjusted operating margin of 10.1% for 2012. GAAP income from operations increased $15.0 million, or 28.5%, to $67.6 million from $52.6 million for 2012. GAAP operating margin was 11.1% and 10.1% for 2013 and 2012, respectively.

The effective tax rate for 2013 was 38.3%, compared with 37.7% for the same period in the prior year. The increase in the effective tax rate was primarily related to a change in state tax laws in November 2012.

Adjusted net income for 2013 increased 15.5% to $37.9 million, or a 6.2% adjusted net income margin compared with adjusted net income of $32.8 million, or a 6.3% adjusted net income margin, for 2012. GAAP net income for 2013 increased to $41.4 million from $32.6 million for 2012, and GAAP net income margin was 6.8% and 6.2% for 2013 and 2012, respectively.

Adjusted diluted earnings per share for 2013 increased 13.2% to $2.19, compared with $1.93 adjusted diluted earnings per share for 2012. GAAP diluted earnings per share for 2013 was $2.39, compared with $1.92 for 2012.

Liquidity and Capital Resources

As of December 31, 2013, IPC had approximately $59.7 million in liquidity, composed of $25.0 million in cash and cash equivalents, and an available line of credit of $34.7 million. IPC had borrowings of $90.0 million from its line of credit outstanding at December 31, 2013.

Net cash provided by operating activities for 2013 was $36.8 million compared with $39.8 million for 2012. The change in working capital during 2013 was largely related to an increase in accounts receivable of $24.0 million, an increase in prepaid expenses and other current assets of $2.1 million, an increase in accounts payable and accrued liabilities of $1.2 million, a net increase in medical malpractice and self insurance reserves of $2.5 million, and an increase in accrued compensation of $6.5 million. Days sales outstanding (DSO), which is used to measure the effectiveness of collections, was 56 DSO as of December 31, 2013, compared with 52 DSO as of December 31, 2012. The increase in DSO is primarily related to the buildup of receivables from acquired practices and delayed Medicaid parity payments.

Net cash used in investing activities was $108.0 million for 2013, compared with $66.2 million for 2012. Cash of $104.1 million was used in 2013 for physician practice acquisitions and contingent payments on prior acquisitions, compared with $62.6 million in 2012.

For 2013, net cash provided by financing activities was $80.0 million, compared with $24.8 million for 2012. During 2013, the Company borrowed $105.0 million from its revolving line of credit to fund new acquisitions and pay for contingent considerations of acquired practices, and repaid $35.0 million to its revolving line of credit with cash generated from our operating activities.

Full Year 2014 Guidance

The Company expects revenue to be in the range of $720 million to $732 million, an adjusted EBITDA range of $76 million to $79 million, and adjusted diluted earnings per share to be in the range of $2.41 to $2.51. The Company has provided this outlook based on assumptions of (i) weighted average shares outstanding of 17.6 million for the year, (ii) a 38.3% effective tax rate, (iii) $8.4 million in stock based compensation expense, and (iv) $6.0 million in depreciation and amortization expense. Not included in the assumptions are (i) new market acquisitions completed after today’s date, or (ii) future gains or losses related to changes in the fair value of contingent consideration of acquired practices.

Reconciliation of Non-GAAP Financial Measures

This press release contains non-GAAP financial measures related to income from operations, net income and diluted earnings per share. During the three and twelve months ended December 31, 2013 and 2012, the Company reported change in fair value of contingent consideration for acquired practices as operating expense pursuant to GAAP, which is referred to in this press release as the “net change in fair value of contingent considerations” or “net change in fair value”.

The fair value of accrued contingent consideration is determined using the income approach for estimating future consideration to be paid based on projected earnings of acquired practices as of specified measurement dates. Because accrued contingent consideration is generally based on a certain multiple of earnings of the acquired practices during a specified measurement period, a relatively small or moderate change in such projected earnings may result in a material change to the fair value of such contingent consideration liability with a corresponding adjustment to income from operations.

During the three months ended December 31, 2013 and 2012, the Company recorded an increase to expense of $340,000 and a reduction to expense of $187,000, respectively, as a net change in fair value. During the twelve months ended December 31, 2013 and 2012, the Company recorded a reduction to expense of $5.7 million and an increase to expense of $0.3 million, respectively, as a net change in fair value.

In this press release, income from operations, net income and diluted earnings per share have been adjusted to exclude the amount of the net change in fair value. The Company believes that these non-GAAP financial measures are useful to management and investors reviewing financial and business trends related to its results of operations, and that when these non-GAAP financial measures are viewed with GAAP financial measures, investors are provided with a meaningful understanding of IPC’s ongoing operating and financial performance. These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. The following unaudited table reconciles non-GAAP financial information to net income per diluted share, which the Company believes are the most comparable GAAP measures (dollars in thousands, except for per share data):
