Ecopetrol's (EC) Brazilian unit launched a voluntary tender offer to acquire about a 25% stake in Brava Energia at $23 Brazilian real ($4.59) per share, representing 116.1 million shares, Ecopetrol said Tuesday.
The offer represents a roughly 20.9% premium to the 90-day volume-weighted average price and is part of a broader deal that could give Ecopetrol a 51% controlling stake.
The tender offer will remain open until June 25, it added.
