CMIG4.SA DCF valuation: where the gap comes from

At a recent price of 11.69, Companhia Energética de Minas Gerais - CEMIG (CMIG4.SA) trades 46% below TickerWorth's blended fair value of 21.69 per share — a discounted-cash-flow model cross-checked against peer multiples and asset value — meaning the market currently prices CMIG4.SA undervalued vs our estimate of what the business is intrinsically worth. Our fair value sits above the market, an implied +85.5% move to close the gap if the business performs in line with our assumptions. This is an educational model, not a price target or a recommendation — the value moves with the inputs, which you can test yourself using the WACC slider below.

Read the full reasoning

One of the lenses behind that blended figure is a discounted-cash-flow model, which on its own values CMIG4.SA at about 29.15 per share. The rest of this page walks through that DCF — its assumptions, reverse-DCF and discount-rate sensitivity — because it is the auditable anchor of the blend.

The valuation discounts Companhia Energética de Minas Gerais - CEMIG's projected free cash flows at a weighted-average cost of capital (WACC) of 8.1%, with a long-run terminal growth rate of 2.5%. About 77% of the enterprise value comes from the terminal value — the portion beyond the explicit forecast window — which is typical for a stable, cash-generative business and a reminder that small changes in the discount rate or terminal growth assumption swing the intrinsic value meaningfully.

Running the DCF in reverse — solving for the growth the current price already assumes — the market is implying roughly -10.8% annual revenue growth for CMIG4.SA. Our base case instead compounds to about 3.7% a year over the same forecast, so the market is pricing in slower growth than our base case. The reverse-DCF is a quick sanity check: it reframes 'is this stock cheap?' as 'do I believe the growth the price requires?' rather than arguing over a single point estimate of fair value.

Sensitivity matters more than any single number. Across a reasonable band of discount-rate assumptions, CMIG4.SA's modeled DCF value ranges from about 18.85 to 55.71 per share. If that range still sits below today's price, the market is optimistic relative to the model across the whole band; if it brackets the price, the stock is roughly fairly valued on our assumptions. Use the interactive slider to see exactly where your own cost-of-capital view lands.

How to read this page: the DCF fair value is what Companhia Energética de Minas Gerais - CEMIG would be worth if its cash flows grow as modeled and are discounted at the stated WACC. The assumptions table shows every input and its source; the reverse-DCF shows what the market believes; the sensitivity band shows how fragile the answer is. None of this is investment advice — it is a transparent, auditable framework for forming your own view of CMIG4.SA's intrinsic value. Figures update as new filings and prices come in.
