Insights

Infrastructure & Utilities Analyst

Asset swap concentrates AXIA in IE Garanhuns and monetizes IE Madeira.

Eletrobras, via AXIA Energia, is rebalancing its transmission portfolio by selling a 49% minority stake in IE Madeira and acquiring full control of IE Garanhuns. The deal includes a BRL 1.174 billion payment tied to these reciprocal transactions.

IE Garanhuns is a smaller but less leveraged asset, with 2025 RAP of BRL 157.9 million, EBITDA of BRL 134.2 million, and net debt of BRL 42.6 million, compared with IE Madeira’s higher RAP and EBITDA but net debt of BRL 588 million. Concentrating ownership simplifies governance and may ease capital allocation.

The company highlights consistency with its strategic plan focused on optimizing minority stakes, capital discipline, and corporate simplification. The transaction is still subject to customary market conditions and adjustments, so timing and final financial impact will depend on regulatory and contractual completions disclosed in future filings.
