IPC The Hospitalist Company Reports First Quarter 2014 Financial Results

North Hollywood, CA—April 23, 2014—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, 2014. 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.

First Quarter 2014 Highlights (comparisons are to first quarter 2013):

Adam D. Singer, M.D., Chief Executive Officer of IPC The Hospitalist Company, said, “We are very pleased to have achieved growth of 13% in revenues, despite the spike last year in encounters from the unusual flu epidemic, plus severe weather conditions this year. While our operations were affected in the first quarter by the continued assimilation of 2013 acquisitions, the exit from a few contracted facilities and the impact of certain under-performing practices, overall our results for this quarter were in line with our internal forecast.”

Dr. Singer added, “We continue to anticipate seeing the benefit of our expanded recruiting resources in the second half of this year and coupled with our acquisition pipeline we are excited about the growth opportunities in both the acute and post-acute arenas for 2014 and beyond.”

First Quarter 2014

Patient encounters for the three months ended March 31, 2014 increased by 188,000, or 11.9%, to 1,764,000, compared with 1,576,000 for the same period in the prior year. Net revenue for the three months ended March 31, 2014 was $172.7 million, an increase of $19.6 million, or 12.8%, from $153.1 million for the same period in the prior year. Of this $19.6 million increase, 63% was attributable to same-market area growth, including tuck-in acquisitions and new hires, and 37% was attributable to revenue generated from operations in new markets. Same-market revenue increased 8.1%, same-market encounters increased 6.5%, and same market patient revenue per encounter decreased 0.8%. The 0.8% decrease is largely due to the automatic cut in Medicare payments triggered by sequestration effective April 1, 2013. The remaining increase in same-market revenue was attributable to an increase in hospital stipends and medical directorship revenues.

Physician practice salaries, benefits and other expenses for the three months ended March 31, 2014 were $127.3 million, or 73.7% of net revenue, compared with $112.1 million, or 73.2% of net revenue, for the same period in the prior year. As a percentage of revenue, physician costs increased by 50 basis points compared to the prior year quarter. This increase is largely the result of the ongoing integration of 2013 acquisitions, the exit from certain contracted facilities and the impact of certain under-performing practices. 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 $3.8 million, or 15.9%, to $27.6 million, or 16.0% of net revenue, for the three months ended March 31, 2014, compared with $23.8 million, or 15.6% of net revenue, for the three months ended March 31, 2013. 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 costs of supporting the Company’s post-acute business, expansion of the Company’s recruiting resources and other expenses. Excluding stock-based compensation, general and administrative expenses were 14.8% of net revenue for the three months ended March 31, 2014, compared with 14.4% of net revenue for the same period of 2013.

The net change in fair value of contingent consideration (“net change in fair value”) for acquisitions was a reduction to expense of $383,000 and $1,093,000 for the three months ended March 31, 2014 and 2013, respectively.

Adjusted EBITDA for the three months ended March 31, 2014 increased 3.8% to $17.8 million, or an adjusted EBITDA margin of 10.3%, compared with adjusted EBITDA of $17.2 million, or an adjusted EBITDA margin of 11.2% for the same period in 2013. The adjusted EBITDA margin decreased 90 basis points quarter-over-quarter. This decrease in margin is primarily related to increased practice and general and administrative costs as a percentage of revenue.

The effective tax rate for the three months ended March 31, 2014 and 2013 was 38.3%.

Adjusted net income for the three months ended March 31, 2014 increased 2.1% to $10.0 million, or a 5.8% adjusted net income margin, compared with adjusted net income of $9.8 million, or a 6.4% adjusted net income margin, for the same period in 2013. GAAP net income for the three months ended March 31, 2014 decreased to $10.3 million from $10.5 million for the three months ended March 31, 2013, and GAAP net income margin was 5.9% and 6.9% for the three months ended March 31, 2014 and 2013, respectively.

Adjusted diluted earnings per share for the three months ended March 31, 2014 and 2013 was $0.57. GAAP diluted earnings per share for the three months ended March 31, 2014 was $0.58, compared with $0.61 for the same period in 2013.

Liquidity and Capital Resources

As of March 31, 2014, IPC had approximately $63.0 million in liquidity, which is composed of $23.3 million in cash and cash equivalents, and an available line of credit of $39.7 million. IPC had borrowings of $85.0 million from its revolving line of credit outstanding at March 31, 2014.

Net cash provided by operating activities for the three months ended March 31, 2014 was $10.2 million compared with $13.9 million for the same period in 2013. The change in working capital during the three months ended March 31, 2014 was largely related to an increase in accounts receivable of $14.1 million, a decrease in prepaid expenses and other current assets of $4.3 million, an increase in accounts payable and accrued liabilities of $4.3 million, and an increase in accrued compensation of $2.8 million. Days sales outstanding (DSO), which is used to measure the effectiveness of collections, was 58 DSO as of March 31, 2014, compared with 56 DSO as of December 31, 2013. The increase in DSO is primarily related to delayed Medicaid parity payments and a buildup of receivables from acquired practices. 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.

Net cash used in investing activities was $9.5 million for the three months ended March 31, 2014, compared with $10.8 million for the same period in 2013. Cash of $8.7 million was used during three months ended March 31, 2014 for physician practice acquisitions and contingent consideration payments on prior acquisitions, compared with $9.7 million in the same period of prior year.

For the three months ended March 31, 2014, net cash used in financing activities was $2.4 million, compared with net cash provided by financing activities of $1.7 million for the same period in 2013. In January 2014, the Company repaid $5.0 million of its outstanding revolving line of credit with cash generated from its operating activities.

2014 Guidance

The Company reaffirms its guidance for the full year 2014 and 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 of adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA), adjusted net income and adjusted diluted earnings per share.

During the three months ended March 31, 2014 and 2013, the Company reported a 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 consideration” or “net change in fair value”. The fair value of accrued contingent consideration is largely 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 March 31, 2014 and 2013, the Company recorded a reduction to expense of $383,000 and $1,093,000, respectively, as a net change in fair value. In this press release, GAAP financial measurements of net income and diluted earnings per share, as well as a non-GAAP financial measurement of EBITDA have been adjusted to exclude the amount of the net change in fair value of contingent consideration. 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.
