CIG vs ELPC: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CIG and ELPC share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CIG and ELPC exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Cemig, incorporated in 1952 and headquartered in Belo Horizonte, is one of Brazil's largest integrated electric utilities and reports across six segments: Generation, Transmission, Trading, Distribution, Gas and Investees. As of December 31, 2025 it operated ~32 hydroelectric plants totaling ~4,434 MW, ~2 wind farms at ~71 MW and ~12 photovoltaic stations at ~169 MW, alongside ~365,577 miles of distribution lines and ~4,865 miles of transmission lines. Cemig D, the distribution arm, is the earnings anchor and serves the great majority of municipalities in Minas Gerais, Brazil's fourth-largest state economy. Gas distribution runs through Gasmig, and the trading arm sells into Brazil's expanding free market (mercado livre), where large and now mid-sized consumers choose their own supplier.

Companhia Paranaense de Energia, universally called Copel, is the integrated electric utility of Parana in southern Brazil, founded in 1954 and listed on the NYSE since 1997. It runs three things that matter: Copel Distribuicao, the regulated wires business serving roughly 5 million consumer units across nearly all of the state; Copel Geracao e Transmissao, a generation fleet of about 6 GW that is overwhelmingly hydro plus wind, along with thousands of kilometres of transmission lines; and an energy trading arm. Distribution earns a regulated return on an asset base set by the national regulator ANEEL, transmission earns a contracted annual allowed revenue, and generation sells under long-term contracts with a merchant tail. All figures the company reports are in Brazilian reais (R$).

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CIG drivers: A ~R$44 billion capex plan through 2028 that grows the regulated asset base; Distribution tariffs and loss control.
• ELPC drivers: The distribution tariff review reset the earnings base; Cost discipline after the 2023 corporatization.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Currency is the first-order risk: every real of earnings converts to fewer dollars when the real weakens, and the ADS price and dividend both absorb that directly. For ELPC, currency is the risk a US buyer underestimates.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CIG if you believe its drivers more; ELPC if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CIG and ELPC guides.

CIG. Cemig reports in Brazilian reais, so the dollar figures above are conversions and move with the exchange rate on their own. Full-year 2025 revenue was ~R$42.75 billion, up ~7.4%, and the 52-week ADS range of ~$1.88 to ~$2.76 shows how much the currency and the political narrative swing a stock whose underlying revenue is regulated. The next scheduled report is August 13, 2026.

ELPC. Because one ADS represents four common shares, per-share screening data on ELPC is frequently wrong: sites that divide the dollar ADS price by a per-common-share earnings figure produce a price-to-earnings ratio several times too high. The cleaner comparison is market capitalisation against annual net income and EBITDA, both taken in Brazilian reais. Copel also emphasises recurring numbers, which exclude asset sales, provisions and other one-off items, so a reader comparing headline growth to the audited statements should check which basis is being quoted.

Headline figures (approximate, August 2026): CIG shows share price (ads) ~$2.10 (August 7, 2026), market cap ~$7.1 billion, revenue (ttm) ~$8.3 billion (~R$44 billion), net income (ttm) ~$927 million, down ~31% year over year; ELPC shows ads price ~$10.67 on the NYSE (the underlying CPLE3 shares trade in Brazilian reais on B3), market capitalisation ~$7.9 billion, revenue (ttm) ~R$28 billion in Brazilian reais, roughly $5.4 billion converted, recurring ebitda (2q26) ~R$1.61 billion (Brazilian reais), up ~20.8% year over year.

CIG and ELPC are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
