Petro Rio S.A. (BOVESPA:PRIO3) will look for M&A. Milton Salgado Neto, Chief Financial Officer said, "there's no change in the leverage because we bring in cash, but we also add more debt. But this is opportunistic, cheap money also with a long duration, and this is great for us. And we will invest that in the best way possible according to the opportunities, M&A activities and CapEx".
