SAO PAULO–Telefonica Brasil SA’s (VIV, VIVT4.BR) first-quarter net profit dropped 18.4% on the year, due to the rise in its debt-service and operational costs, it said Thursday.

The company, which is controlled by Spain’s Telefonica SA (TEF, TEF.MC), posted a net profit of 660.8 million Brazilian reais ($296 million), down from BRL810.2 million in the year-ago period.

Telefonica’s debt-service costs totaled BRL626 million in the first quarter, almost double compared with BRL381 million in the year-ago period. The company’s debt-service costs increased, among other reasons, because of the interest rate increase in Brazil.

In the meantime, net revenue totaled BRL8.61 billion in the first quarter, up just 0.7% from BRL8.55 billion a year ago.
