Addus HomeCare Reports Fourth Quarter 2013 Results

Fourth Quarter Financial Highlights

Palatine, IL, March 12, 2014 – Addus HomeCare Corporation (Nasdaq: ADUS), a comprehensive provider of home and community based services, which are primarily social in nature and provided in the home, and focused on the dual eligible population, announced today its financial results for the fourth quarter and year ended December 31, 2013.

Mark Heaney, President and Chief Executive Officer of Addus HomeCare, stated: “We are pleased to see continued steady improvement in our organic growth rate. The completion of our new acquisitions in New Mexico in December and Tennessee and Ohio in January adds to our footprint in key managed care states. We are also moving forward to compete the implementation of technology investments to leverage the results of our growth”

Fourth Quarter Review

Total net service revenues for the fourth quarter of 2013 were $69.9 million, a 9.6% increase compared to $63.8 million in the prior year quarter. Revenues from same stores increased to $68.2 million, a 6.9% increase over the prior year with new acquisitions making up the difference. The growth in revenues is attributable to an 7.9% increase in average census in the quarter for our same stores, and a 5.3% increase (1,359 new clients) from acquisitions, offset by a slight decline in average billable hours per client per month. (See comment about State of Illinois billing changes below.)

Gross profit for 2013 increased to $18.1 million representing a 3.2% year-over-year growth rate. Gross profit margin declined by 1.6% of revenue to 25.9%. Modified billing procedures by the State of Illinois reduced operating profit by $600,000 in the fourth quarter of 2013 as compared to fourth quarter of 2012. Without this change in billing processes the decline in our gross profit margin was 0.7% year-over-year. The impact of the loss of this billing process in Q4 of 2013 was to depress earnings by $0.04 per share in the quarter and for the year.

Operating income from continuing operations for the fourth quarter of 2013 declined 33.9% to $3.5 million, or 5.0% of revenue, compared to $5.3 million, or 8.2% of revenue, in the prior year quarter. In addition to investments in telephony, IT and other infrastructure, this decline was also caused by:

Income tax expense was $192,000, or 5.8% of income from continuing operations before taxes. This favorable tax rate is the result of our ability to capture higher than expected Work Opportunity Tax Credits and other tax credits affecting both our 2012 and 2013 tax years. The impact of this favorable tax rate was to increase earnings in the quarter by $0.06 per diluted share.

Net income from continuing operations for the fourth quarter was $3.1 million, a 10.8% decline when compared to the prior year, primarily the result of $662,000 in one-time costs related to acquisitions and $281,000 related to expenses required for our Sarbanes-Oxley Act Section 404 (“SOX 404”) compliance activities.

After considering the one-time costs associated with our M&A efforts, the change to the billing process, the cost for SOX 404 compliance and the impact of the reduced tax expense discussed above, our adjusted EPS for the quarter from continuing operations would have been $0.32 per diluted share, equal to 2012 reported results.

As a result of our Discontinued Operations, we recorded a $2.2 million, net of tax, reduction to the gain on the sale of the Home Health business in the 4^th quarter of 2013. The reduction in the gain is the result of recording a $3.2 million pretax reserve for the potential recovery of Medicare billings for the six-year period prior to the date of the closing of the sale of the business. This reserve is intended to be used to settle amounts recovered by the programs under their audit procedures and is reflective of our estimated reserve needs. Net income, including a loss from discontinued operations, was $0.9 million, or $0.08 per diluted share.

Cash flow for the quarter was a negative $13.9 million, primarily due to the $11.8 million expenditure for acquisitions closed during the quarter, and lower collections from the State of Illinois, offset by positive cash generated from operations.

Twelve Month Review

Total net service revenues for the twelve months ended December 31, 2013 were $265.9 million, a 8.9% increase compared to $244.3 million for the prior year. Revenues from same store sales increased to $264.2 million, an 8.2% increase over the prior year with new acquisitions making up the difference. Net income from continuing operations for the

twelve months ended December 31, 2013 increased 20.2% to $11.2 million, or $1.01 per diluted share, compared to $9.3 million, or $0.86 per diluted share, in the prior year. Net income, including the loss from discontinued operations and the gain from the sale of the home health business was $19.1 million, or $1.73 per diluted share.

Operating income from continuing operations increased 2.0% to $15.5 million, or 5.8% of revenue, for the twelve months ended December 31, 2013. This compares to $15.2 million or 6.2% of revenue in 2012, after adjusting operating income for the benefit of a $0.5 million gain on a sale of an agency realized in 2012.

Income taxes for the year were $3.8 million and include approximately $2.2 million in Work Opportunity Tax Credits and Empowerment Zone credits with $600,000 related to 2012 as the tax law change enacted in early 2013 included a retroactive effective date of January 1, 2012. Had the tax law been in effect for the two years without interruption, our effective tax rate for 2013 would have been 29.5%.

As a result of the Company’s increased stock price and overall market value as of the end of the second quarter of 2013, the Company became subject to the requirements of SOX 404. Accordingly, the Company is now required to have an audit of its internal controls over financial reporting. The Company believes material weaknesses in internal controls over financial reporting existed as of December 31, 2013, principally related to general controls over its information technology, including user access and change management activities and to overall controls related to its payroll system and related processes. The Company will engage an expert consultant to assist in enhancing the controls over its information technology; in addition, the Company has selected the vendor for a new payroll system that will address the control issues in that area and will engage an expert consultant to assist in the implementation. The Company will report such material weakness in Item 9A of its Annual Report on Form 10K for the 2013 fiscal year. The Company does not believe that the material weakness will impact the accuracy of the Company’s financial statements to be reported in its 2013 Form 10-K.

Subsequent Events

In January 2014, the Company completed the acquisition contemplated by the previously announced agreement to acquire all of the personal care operations of the Medi Home Private Care Division of Medical Services of America, Inc. The acquisition includes two agencies located in South Carolina, four agencies located in Tennessee, and two agencies located in Ohio.

The asset purchase agreement provided for separate closings with respect to the operations in each state. The closing related to the agencies in South Carolina took place effective November 1, 2013, with the operations being integrated into existing agencies in South Carolina. Accordingly, the results are included in the reported results for same store sales. The operations in Ohio and Tennessee closed in January 2014 and will be reported as part of new acquisitions beginning in the first quarter of 2014.

Revenues in the first quarter will be negatively impacted by severe winter weather experienced during January and February affecting 65 to 70% of our offices. Census for the period reflects modest growth with a decline in hours served per client per month attributable to the weather.

Non-GAAP Financial Measures

The information provided in this release includes Adjusted EBITDA, a non-GAAP financial measure, which the Company defines as earnings before discontinued operations, interest expense, taxes, depreciation, amortization, and stock-based compensation expense. The Company has provided, in the financial statement tables included in this press release, a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP measure. Management believes that Adjusted EBITDA is useful to investors, management and others in evaluating the Company’s operating performance, to provide investors with insight and consistency in the Company’s financial reporting and to present a basis for comparison of the Company’s business operations among periods, and to facilitate comparison with the results of the Company’s peers.
