Dirk Allison, President and Chief Executive Officer of Addus HomeCare, commented, “Overall, for the first quarter we experienced substantial revenue growth across all our service segments, reflecting favorable demand trends and strong operational discipline. Even as most of the states where we operate have been under “shelter in place” orders since mid-March, we have continued to provide the critical and essential home care services that allow individuals to remain in their homes. We are proud of our financial results for the first quarter that we achieved while enduring significant operational challenges related to the COVID-19 pandemic that we began to see in March.”

Allison noted further, “Obviously, much has changed in our operating environment since the end of the first quarter. But our primary focus has remained on the health and safety of our caregivers and other employees and the patients and customers we serve. The COVID-19 pandemic has created new challenges for our business with heightened emphasis on providing our services in a safe manner, as well as the economic impact on the communities we serve. We are following published guidelines by the Centers for Disease Control and other public health authorities and have implemented procedures with respect to social distancing, health monitoring, enhanced cleaning protocols, and care coordination. Our internal task force meets daily, and our senior leadership team continues to analyze and address various evolving issues surrounding the COVID-19 pandemic and its impact on the Company’s operations.”

Mr. Allison added, “Looking ahead, we will continue to execute our growth strategy as a leading provider of home care services. In addition to organic growth opportunities, we have a solid pipeline of potential acquisitions, although we are, of course, approaching the consummation of any acquisition with all appropriate caution and diligence.

“Addus offers a strong value proposition, including through our expanding hospice and home health services, and we are well positioned to meet the current and expected demand for our services. We recognize the dedication of our caregivers and of all healthcare workers, and we are proud of the heroic work being performed across our operations every day. Our caregivers’ services during this important time will enable many elderly and vulnerable individuals to avoid the risks found in settings outside of their homes during this unprecedented time.”

Non-GAAP Financial Measures

The information provided in this release includes adjusted net income, adjusted EBITDA and adjusted diluted earnings per share, which are non-GAAP financial measures. The Company defines adjusted net income as net income before the net-of-tax amounts of interest income from the state of Illinois, COVID-19 expenses, M&A expenses, stock-based compensation expense, restructure charges, severance and other costs. The Company defines adjusted EBITDA as net income before interest expense, interest income, other non-operating income, COVID-19 expenses, taxes, depreciation, amortization, interest income from the State of Illinois, M&A expenses, stock-based compensation expense, restructure charges, severance and other costs. The Company defines adjusted diluted earnings per share as earnings per share adjusted for interest income from the State of Illinois, COVID-19 expenses, M&A expenses, stock compensation expense and restructure expense, severance and other costs. The Company has provided, in the financial statement tables included in this press release, a reconciliation of adjusted net income to net income, a reconciliation of adjusted EBITDA to net income and a reconciliation of adjusted diluted earnings per share to earnings per share, in each case, the most directly comparable GAAP measure. Management believes that adjusted net income, adjusted EBITDA and adjusted diluted earnings per share are 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. With respect to COVID-19 expenses, the Company views these expenses as unrelated to the Company’s long-term performance, since they are directly related to the sudden onset COVID-19 pandemic.
