This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row.

Companhia Energética de Minas Gerais - CEMIG declared BRL 1.23 per local share for Dec 2025. It reports in Brazilian reais, and one US-listed share can stand for several local shares, so we do not set this against the dollar price or show a yield.

Companhia Energética de Minas Gerais - CEMIG is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

Companhia Energética de Minas Gerais - CEMIG earned BRL 945 M of net profit in the Jun 2026 quarter, −20.4% on the same quarter a year earlier. Full-year FY25 profit was BRL 4.9 B. Over 4 years profit has grown 6.9% a year on average. That is 8.5% of the quarter's revenue.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

The same quarter a year earlier earned BRL 1.2 B.

For the full year, FY25 profit was BRL 4.9 B (−31.2% on the year before).

Why profit moved: revenue changed +3.4% on a year earlier and the margin moved +0.6 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed −3.5% and revenue +4.3%. Profit is growing slower than sales: rising costs are taking part of the growth.

Companhia Energética de Minas Gerais - CEMIG reported BRL 11.2 B of revenue in the Jun 2026 quarter, +3.4% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 4 years it has grown 6.2% a year on average.

Revenue is everything the company billed its customers in the period.

The last full year, FY25, came in at BRL 42.8 B. The last four reported quarters add to BRL 43.7 B.

FY25 revenue was BRL 42.8 B, +7.4% on the year before.

Recent pace: the last four quarters grew +4.3% on average, against 6.2% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +4.3%, against +7.5% a year over the last 8 quarters (rolling over); profit over the last 12 months grew −29.3%, against −12.2% a year (rolling over).

Companhia Energética de Minas Gerais - CEMIG's operating margin was 15.6% in the Jun 2026 quarter, 0.6 percentage points higher than the same quarter a year ago. Across 5 years it has been between 14.0% and 17.8%. The latest quarter is within that range.

Operating margin is what is left from every BRL 100 of sales after the costs of running the business, before interest and tax. It shows pricing power and cost control.

Why: the operating margin move is clear, but the cost details behind it are not in our data, so we show the move without guessing the reason.

Over the last 3 years, 91% of Companhia Energética de Minas Gerais - CEMIG's reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in BRL 4.1 B of operating cash against BRL 4.9 B of profit.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

After BRL 699 M of spending on assets, BRL 3.4 B was left over as free cash.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

This company reports in Brazilian reais, not US dollars, so the money charts are left out here. The figures in the text are in that currency (BRL); nothing is converted.

Companhia Energética de Minas Gerais - CEMIG does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent BRL 2.4 B on assets over the last 3 years. Averaged over those years that is 1.9% of FY25 revenue a year.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn.

Spending on assets: BRL 2.4 B over the last 3 years.

In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns.

Companhia Energética de Minas Gerais - CEMIG's P/E is 6.2×, with too little history to compare. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many dollars the market pays for each dollar of yearly profit.

In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple.

Companhia Energética de Minas Gerais - CEMIG's business is giving mixed signals. There is no clear direction across the growth lines, with ROCE steady at 12.0%; each line tells part of the story. This is based on 12 quarters of 3 measures, with some gaps.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: when the lines disagree, each line above matters more than any single label.

This reading has some gaps: at least one line is short, or the return line is not the quarterly series, so treat it with a little more caution.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the stock price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

Companhia Energética de Minas Gerais - CEMIG earned a ROE of 17% in FY25. Its return on capital used (ROIC) is 2.7 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 11.5% net margin and 0.64× asset turnover (sales divided by assets).

Return on equity (ROE) is the profit the business earns on its shareholders’ money. We do not have the full capital split, so ROE is the longest history we can draw here.

Why the return is what it is (FY25): a 11.5% net margin × 0.64× asset turnover × 2.35× leverage (assets divided by equity) ≈ 17.3% on equity. The margin does its share; borrowing is a big part of it.

The key test, return on capital used minus the cost of capital: 8.3% − 5.6% = +2.7 percentage points. The 5.6% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. Positive but thin: it creates value with little room for error.

Companhia Energética de Minas Gerais - CEMIG has total debt of BRL 22.7 B against shareholder equity of BRL 29.2 B as of Jun 2026, so its debt is 0.78× its equity. Year by year, that ratio went from 0.60 in FY21 to 0.70 in FY25. Keep that borrowing in mind when reading the returns on this page.

Debt-to-equity shows how much of the business is paid for with borrowed money. Lower is safer, and the direction matters as much as the level.

This company reports in Brazilian reais, not US dollars, so the money charts are left out here. The figures in the text are in that currency (BRL); nothing is converted.

0.1% of Companhia Energética de Minas Gerais - CEMIG's tradable shares are in short positions, which are bets that the price will fall, so very few traders are betting against this stock. At normal trading volumes, closing those positions would take about 0.6 days. It is a single reading at one point in time; we do not have its history.

There is no quarter-by-quarter list of owners here, so we look at short interest: the share of tradable shares held in short positions, which gain if the price falls.

US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead.

Why it is at this level: the figure does not say who has the short positions or why, so we show the level without guessing the story.
