Volume and revenue. RVUs related to service fee revenues in the six-month period ended June 30, 2021 were 3,174 (in thousands) compared to 2,619 in the six-month period ended June 30, 2020. Excluding or pro rating for the contribution from 2021 Acquisitions, on a same-center basis, RVUs were 3,086 in the three-month period ended June 30, 2021 compared to 2,612 in the six-month period ended June 30, 2020, which represents an increase of approximately 18%. The same-center growth represents recovery from the lower volumes in the six-months ended June 30, 2020 due to impact of COVID-19.
Revenue was $133,459 and $115,535 for the six-month periods ended June 30, 2021 and 2020, respectively. The variance is mainly due to higher volume (approximately 21% overall as compared to 18% growth on a same-center basis) and lower service fee revenue per RVU (approximately 4% lower). The lower volume in 2020 was due to the economic environment and reduced demand for imaging services as a result of the COVID-19 pandemic and related government “stay-at-home” orders and other restrictions, as well as patients deferring elective procedures, which would have required our imaging services, due to the pandemic. Further, in February 2021, an ice storm disrupted our operations in Central Texas. As a result, some patients were unable to attend procedures and some centers were not available for use. The lower service fee per RVU mainly resulted from payor and service mix. Going forward, the Company expects organic growth to be in the mid-to-lower single digits, however, the COVID-19 pandemic may result in fluctuation of organic growth rates over time.
In the six-month period ended June 30, 2021, approximately 10% of service fee revenue was earned from attorney payors, compared to approximately 9% in the six-month period ended June 30, 2020.
Employee compensation. Payroll and staffing costs, as a percentage of revenue, remained consistent at 35% in the six-month period ended June 30, 2021 compared to the six-month period ended June 30, 2020. Expenses for employee compensation were approximately $6,210 higher for the six-month period ended June 30, 2021 compared to the six-month period ended June 30, 2020 due mainly to the Company’s cost containment measures in response to the COVID-19 pandemic and due to 2021 Acquisitions. See “Recent Developments – COVID-19” above.
Reading fees. Reading fees, as a percentage of revenue, remained consistent at 16% in the six-month period ended June 30, 2021 compared to the six-month period ended June 30, 2020. Our reading fees are largely based on the volume of procedures performed. As a result, reading fee expenses are variable and closely correlated to revenue.
Rent and utilities. Rent and utilities, as a percentage of revenue, decreased to 11% in the six-month period ended June 30, 2021 compared to 14% in the six-month period ended June 30, 2020. The decrease in the expense ratio is mainly due to higher revenue in the six-month period ended June 30, 2021.
Third party services and professional fees. Third party services and professional fees, as a percentage of revenue, decreased to 12% in the six-month period ended June 30, 2021 compared to 13% the six-month period ended June 30, 2020. The increase in this cost during the six-month period ended June 30, 2021 is mainly due to gradual easing of cost containment measures in response to the COVID-19 pandemic. See “Recent Developments – COVID-19” above.
Administrative expenses, medical supplies and other expenses. Administrative expenses, medical supplies and other expenses, as a percentage of revenue, remained consistent at around 10% in the six-month period ended June 30, 2021 compared to the six-month period ended June 30, 2020. Administrative expenses, medical supplies and other expenses increased by approximately $2,212 for the six-month period ended June 30, 2021 compared to the six-month period ended June 30, 2020.
Adjusted EBITDA. Adjusted EBITDA for the six-month period ended June 30, 2021 was $20,583 compared to $15,545 for the six-month period ended June 30, 2020. The variance is mainly attributable to higher revenue, partly offset by increases in operating expenses and timing of 2021 Acquisitions. Adjusted EBITDA Margin for the six-month period ended June 30, 2021 was 15% compared to 13% in the six-month period ended June 30, 2020.
Net income (loss) attributable to shareholders of Akumin. The net loss attributable to shareholders of Akumin was $10,231 (8% of revenue) for the six-month period ended June 30, 2021 and net loss for the six-month period ended June 30, 2020 was $10,840 (9% of revenue). The reduction in net loss is mainly due to higher revenue, partly offset by higher operating expenses, acquisition-related and interest costs incurred in the six-months ended June 30, 2021.
