The Managerial performance indicators below show gross revenue, operating expense and EBITDA, all of them per billed cubic meter.

The historical series is presented since 2014, based on quarterly accounting data released by the Company, excluding some non-recurring and significant events that would distort the result.

In order to check the behavior of the period on a same price basis, all indicators were calculated on average values for 1Q20, adjusted by the variation of the Amplified Consumer Price Index (IPCA).

Gross revenue per billed cubic meter shows average growth, especially after 3Q15. 1Q20 shows higher results than 1Q19.

Operating expenses per billed cubic meter increased in a controlled manner, compatible with the expansion of the operations, quarter over quarter, showing flat average behavior and disciplined management of costs.
