Three Months Ended June 30, 2019 as Compared to Three Months Ended June 30, 2018
Our net revenue attributable to continuing operations was $868.3 million for the three months ended June 30, 2019, as compared to $865.0 million for the same period in 2018. The increase in revenue of $3.3 million, or 0.4%, was attributable to an increase in same-unit net revenue and revenue from acquisitions, partially offset by a decline in revenue from the
non-renewal
of certain contracts. Same units are those units at which we provided services for the entire current period and the entire comparable period. Same-unit net revenue grew by $13.0 million, or 1.6%. The increase in same-unit net revenue was comprised of a net increase of $8.9 million, or 1.1%, from patient service volumes and a net increase of $4.1 million, or 0.5%, related to net reimbursement-related factors. The increase in revenue from patient service volumes was related to increases across almost all of our service lines. The net increase in revenue related to net reimbursement-related factors was primarily due to modest improvements in managed care contracting.
Practice salaries and benefits attributable to continuing operations increased $16.0 million, or 2.7%, to $609.0 million for the three months ended June 30, 2019, as compared to $593.0 million for the same period in 2018. This increase was primarily attributable to increased costs associated with physicians and other staff to support organic-growth initiatives, acquisition-related growth and growth at our existing units, of which $7.8 million was related to salaries and $8.2 million was related to benefits and incentive compensation. We anticipate that we will continue to experience a higher rate of growth in clinician compensation expense at our existing units over historic averages, which could adversely affect our business, financial condition, results of operations, cash flows and the trading price of our securities.
Practice supplies and other operating expenses attributable to continuing operations decreased $0.3 million, or 1.1%, to $28.0 million for the three months ended June 30, 2019, as compared to $28.3 million for the same period in 2018. The decrease was primarily attributable to decreases in practice supply, rent and other costs.
General and administrative expenses attributable to continuing operations primarily include all billing and collection functions and all other salaries, benefits, supplies and operating expenses not specifically related to the
day-to-day
operations of our physician practices and services. General and administrative expenses were $103.5 million for the three months ended June 30, 2019, as compared to $100.9 million for the same period in 2018. General and administrative expenses for the three months ended June 30, 2019 included $3.5 million in cost improvements as part of our shared services initiative. General and administrative expenses as a percentage of net revenue was 11.9% for the three months ended June 30, 2019, as compared to 11.7% for the same period in 2018.
Transformational and restructuring related expenses attributable to continuing operations were $27.5 million for the three months ended June 30, 2019, of which $15.4 million related to severance benefits for eliminated positions as well as costs associated with contract terminations and $12.1 million related to external consulting costs for various process improvement and restructuring initiatives.
Depreciation and amortization expense attributable to continuing operations was $19.8 million for the three months ended June 30, 2019, as compared to $20.3 million for the same period in 2018.
Income from operations attributable to continuing operations decreased $41.9 million, or 34.2%, to $80.5 million for the three months ended June 30, 2019, as compared to $122.4 million for the same period in 2018. Our operating margin was 9.3% for the three months ended June 30, 2019, as compared to 14.1% for the same period in 2018. The decrease of 488 basis points was primarily due to higher operating expense growth combined with lower revenue growth.
Net
non-operating
expenses attributable to continuing operations were $27.9 million for the three months ended June 30, 2019, as compared to $19.1 million for the same period in 2018. The net increase of $8.8 million, or 46.1%, was primarily related to an increase in interest expense related to a higher average interest rate on our outstanding debt, driven by the incremental senior notes issuances completed in late 2018 and early 2019.
Our effective income tax rate attributable to continuing operations was 32.5% and 27.6% for the three months ended June 30, 2019 and 2018, respectively.
Income from continuing operations was $35.5 million for the three months ended June 30, 2019, as compared to $74.8 million for the same period in 2018. Adjusted EBITDA from continuing operations was $131.0 million for the three months ended June 30, 2019, as compared to $145.2 million for the same period in 2018.
Diluted income from continuing operations per common and common equivalent share was $0.42 on weighted average shares outstanding of 83.7 million for the three months ended June 30, 2019, as compared to $0.80 on weighted average shares outstanding of 93.5 million for the same period in 2018. Adjusted EPS from continuing operations was $0.89 for the three months ended June 30, 2019, as compared to $0.98 for the same period in 2018. The decrease of 9.8 million in our weighted average shares outstanding is primarily due to the impact of shares repurchased under a 2018 accelerated share repurchase program and through open market repurchase activity in 2018 and 2019.
Loss from discontinued operations was $43.8 million for the three months ended June 30, 2019, reflecting an incremental
non-cash
impairment charge recorded during the three months ended June 30, 2019, as compared to income from discontinued operations of $4.6 million for the same period in 2018. Diluted loss from discontinued operations per common and common equivalent share was $0.52 on weighted average shares outstanding of 83.7 million for the three months ended June 30, 2019, as compared to $0.05 on weighted average shares outstanding of 93.5 million for the same period in 2018.
