Thank you, Ed. Good morning, everyone. I'll begin by providing an overview of our financial results and the primary factors that drove our performance in the first quarter of 2024. Our revenue for the quarter was $2.6 billion, up 4% compared to the prior year. We generated topline growth in both of our business segments on a year-over-year basis. Products & Healthcare Services grew 3%, with Medical Distribution growth in the mid-single digits. And in our Global Products division, we saw growth in our U.S. proprietary product sales.
Patient Direct revenue was up 5%, which was partially impacted by the Change Healthcare cyber incident that slowed our ability to onboard new patients and renew eligibility for existing patients. Gross profit in the first quarter was $536 million or 20.5% of revenue, compared to $497 million or 19.7% of revenue in the first quarter of 2023. Our gross margin expansion of 79 basis points can be attributed to 3 things: First, the profitability expansion in the Products & Healthcare Services segment, driven by efficiency gains and the successful efforts of the operating model realignment program; second, improved collections of patient direct sales, and third, patient direct sales growth, which carries a higher gross margin than Products & Healthcare Services.
Our distribution, selling and administrative expenses for the quarter were $478 million, making up 18% of revenue. The $29 million year-over-year increase reflects higher variable expenses to support the growth in both segments, an increase in our teammate benefits and our decision to make incremental investments throughout the company for future profitable growth. GAAP operating income for the quarter was $10 million, and adjusted operating income was $57 million. Adjusted operating income was up more than 20% year-over-year and was driven by the overall improvements in the Products and Healthcare Services segment.
The Patient Direct segment was impacted by expected investments in its future growth, regulatory reimbursement changes and, to a lesser extent, the Change Healthcare cyber incident. Adjusted EBITDA was $116 million, up $8 million versus the first quarter of 2023. Interest expense for the first quarter was $36 million, a 16% decrease from the first quarter of last year, reflecting our prior work to reduce our total debt in 2023. Our GAAP effective tax rate was 19% and the adjusted effective tax rate was 29%. Our GAAP net loss for the quarter was $22 million or a loss of $0.29 per common share. Adjusted net income for the quarter amounted to $15 million or $0.19 per common share.
The significant increase in adjusted net income was driven by the factors mentioned above. Shifting to our capital structure. And considering the investments we continue to make, as Ed outlined, cash flow generation and the change in debt levels reflected investments across the company, especially in inventory to support Medical Distribution, customer onboardings and to maintain high-quality service levels. As of March 31, our total debt was $2.2 billion, and net debt was $1.9 billion, up about 3% from last year-end. Through the remainder of 2024, we expect minimal net debt reduction as we make investments to drive long-term profitable growth. We remain committed to delivering our 2024 guidance.
As a reminder, we expect revenue to be in the range of $10.5 billion to $10.9 billion, adjusted EBITDA to be in the range of $550 million to $590 million and adjusted EPS to be in the range of $1.40 to $1.70. Also, as a reminder, we expect seasonality to lead to a roughly 1/3, 2/3 split across the first and second halves of the year from the adjusted EPS perspective, and we'd expect to deliver improvement in each sequential quarter.
With that, I'll turn the call over to the operator for the Q&A part of the call.
