family units under construction, combined with our acquisition strategy, will help us navigate any near-term softness created by the April and May declines in single-family housing starts. Overall, our operating and financial results continue to demonstrate the compelling business model we have created, which has allowed us to effectively respond to recent market conditions, while also providing IBP with a strong platform for long-term value creation,” concluded Mr. Edwards.
Second Quarter 2020 Results Overview
For the second quarter of 2020, net revenue was $393.9 million, an increase of 6.0% from $371.8 million in the second quarter of 2019. On a same branch basis, net revenue improved 2.3% from the prior year quarter. Residential same branch sales growth was 2.5% in the quarter, attributable to price gains and more favorable customer and product mix, compared to a decline in total completions of 2.9%. Our large commercial construction end-market increased 7.5% for the second quarter of 2020.
Gross profit improved 18.5% to $127.1 million from $107.3 million in the prior year quarter. Adjusted gross profit* as a percent of total revenue was the highest we have reported as a public company of 32.4% which adjusts for the Company’s share-based compensation expense, branch start-up costs and employee-related expenses associated with the COVID-19 pandemic, compared to 29.0% for the same period last year. Selling and administrative expense, as a percent of net revenue, was 19.8% compared to 18.9% in the prior year quarter. Adjusted selling and administrative expense*, as a percent of net revenue, was 18.9% compared to 18.2% in the prior year quarter. This increase was attributable to higher variable employee expenses and insurance reserves.
Net income was $25.3 million, or $0.86 per diluted share, compared to $18.9 million, or $0.63 per diluted share in the prior year quarter. Adjusted net income* was $33.2 million, or $1.12 per diluted share, compared to $25.9 million, or $0.87 per diluted share in the prior year quarter. Adjusted net income adjusts for the impact of non-core items in both periods, including COVID-19 expenses and an addback for non-cash amortization expense related to acquisitions.
Adjusted EBITDA* was $63.1 million, a 27.1% increase from $49.6 million in the prior year quarter, largely due to higher sales and improved gross profit margin compared to the prior year quarter.
