Commenting on the results, Dirk Allison, Chairman and Chief Executive Officer, said, “Addus had a solid start to 2026, delivering an improved year-over-year financial and operating performance with revenue up 7.7% and adjusted EBITDA up 9.7% over the first quarter last year. These results reflect continued demand for our home-based care services across the continuum. Addus is well positioned to meet this demand as we continue to expand our market reach and add density in the states where we operate. Our hiring trends have been stable and consistent in the first quarter despite some brief winter weather interruptions in January. We are proud of the dedicated caregivers who represent Addus and continue to provide outstanding care and support to the patients and families who rely on us for quality care in their preferred home setting.

“Our personal care business, which accounted for 77.3% of our revenues, was the primary driver of our growth with a 6.5% organic revenue increase over the first quarter last year. We benefitted from higher volumes as well as additional rate support from two key states, including a 9.9% increase in Texas that was effective September 1, 2025, and a 3.9% increase from the State of Illinois that was effective beginning January 1, 2026. We are pleased that our strong value proposition as a cost-effective provider is being recognized by the states where we serve clients.

“Our hospice care business has performed well and accounted for 18.1% of our revenue for the first quarter. We have seen consistent trends in our hospice segment, resulting in 7.7% organic revenue growth over the first quarter of last year and year-over-year improvement in average daily census. Our home health business represented 4.6% of revenue for the first quarter. We believe home health provides important complementary capabilities and clinical collaboration for our personal care and hospice care segments as we see more patients in select markets receive the benefit of the full continuum of care,” said Allison.

Indiana Acquisition Supports Market Expansion

The Company also announced it acquired the personal care operations of HomeCourt Home Care (“HomeCourt”) on May 1, 2026. Based in Fort Wayne, Indiana, HomeCourt serves approximately 240 clients and has annualized revenues of approximately $9.7 million. The Company also entered into a definitive agreement to acquire additional Indiana operations of a similar size to further expand geographic reach in the state, which is expected to close later this year.

Allison added, “We are excited to announce this acquisition, which marks our entry into Indiana, a new market for Addus and our plans to further grow in the state. Acquisitions remain an integral part of our growth strategy, and we are pleased to welcome HomeCourt Home Care to our personal care operations. This transaction and our planned additional transaction are aligned with our strategy of expanding our personal care footprint in select markets and creating density in markets where we operate. We expect the HomeCourt transaction to be immediately accretive to our financial results. We look forward to further expanding our coverage and capabilities in Indiana.”

Cash and Liquidity

As of March 31, 2026, the Company had cash of $103.1 million and bank debt of $94.3 million, with capacity and availability under its revolving credit facility of $650.0 million and $547.8 million, respectively. Net cash provided by operating activities was $52.4 million for the first quarter of 2026.

Allison added, “For the first quarter of 2026, we continued to generate consistent cash flow from operations and maintain a strong balance sheet. Our conservative leverage position allows us flexibility to make strategic investments in our business and to evaluate and pursue additional acquisition opportunities like those announced today. We have a strong development team with a proven track record, and we will continue our disciplined approach focused on both non-clinical and clinical acquisition opportunities where we can increase both density and geographic coverage. We see important synergies in offering the full care continuum as we build scale and expand our market coverage, and we are optimistic that we will see additional acquisition opportunities in 2026.

Looking Ahead

“We are pleased with the favorable trends in our business and believe we have significant opportunities in 2026 for continued organic growth and for deriving additional value from acquired operations. Addus plays an important role in our nation’s health care delivery system as a leading provider of quality, cost-effective care in the preferred home setting. We have a dedicated team of caregivers who work tirelessly every day to provide outstanding care across our markets. We look forward to the opportunities ahead for Addus in 2026 to deliver value to the clients we serve and our shareholders,” added Allison.

Non-GAAP Financial Measures

The information provided in this release includes adjusted net income, adjusted EBITDA, adjusted net income per diluted share and adjusted net service revenue, which are non-GAAP financial measures. The Company defines adjusted net income as net income before acquisition expense, stock-based compensation expense, restructuring and other non-recurring costs, and the gain or loss on the sale of assets. The Company defines adjusted EBITDA as earnings before net interest expense, taxes, depreciation, amortization, acquisition expense, stock-based compensation expense, restructuring and other non-recurring costs, and the gain or loss on the sale of assets. The Company defines adjusted net income per diluted share as net income per share, adjusted for acquisition expense, stock-based compensation expense, restructuring and other non-recurring costs, and gain or loss on the sale of assets.

Management believes that adjusted net income, adjusted EBITDA, adjusted diluted net income per share, and adjusted net service revenues 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.
