A share price tends to move through four phases: moving sideways (stage 1), rising (stage 2), stalling near a high (stage 3) and falling (stage 4). Today Grupo Aeroportuario del Sureste, S. A. B. de C. V. is in stage 4. The phase helps read everything below.

Over the last 10 years the share price moved +73% while the S&P 500 moved +261%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 17 April 2026. The chart above shows the 13-week comparison for every week.

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

Grupo Aeroportuario del Sureste, S. A. B. de C. V. declared MXN 10.00 per local share for Dec 2025. It reports in Mexican pesos, 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.

Grupo Aeroportuario del Sureste, S. A. B. de C. V. is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

Grupo Aeroportuario del Sureste, S. A. B. de C. V. earned MXN 2.2 B of net profit in the Sep 2026 quarter, +2.1% on the same quarter a year earlier. That is the 2nd quarter in a row of profit growth. Full-year FY25 profit was MXN 10.5 B. Over 4 years profit has grown 15.1% a year on average.

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

That is 20.7% of the quarter's revenue. The same quarter a year earlier earned MXN 2.1 B.

For the full year, FY25 profit was MXN 10.5 B (−22.6% on the year before).

Why profit moved: revenue changed +18.9% on a year earlier and the margin moved −4.9 percentage points. Sales did the work while the margin got thinner.

On average over the last four quarters, profit changed −7.8% and revenue +12.6%. Profit is growing slower than sales: rising costs are taking part of the growth.

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

Grupo Aeroportuario del Sureste, S. A. B. de C. V. reported MXN 10.4 B of revenue in the Sep 2026 quarter, +18.9% on the same quarter a year earlier. That is the 11th quarter in a row with growth on the year before. Over 4 years it has grown 18.7% a year on average.

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

The last full year, FY25, came in at MXN 37.2 B. The last four reported quarters add to MXN 39.8 B.

FY25 revenue was MXN 37.2 B, +18.8% on the year before.

Recent pace: the last four quarters grew +12.6% on average, against 18.7% 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 +12.7%, against +16.7% a year over the last 8 quarters (rolling over); profit over the last 12 months grew −10.8%, against −11.3% a year (stabilising).

Grupo Aeroportuario del Sureste, S. A. B. de C. V.'s operating margin was 37.3% in the Sep 2026 quarter, 4.9 percentage points lower than the same quarter a year ago. Across 5 years it has been between 45.6% and 59.0%. The latest quarter is below every full year in that period.

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

Why the margin moved: operating margin changed −4.9 percentage points on the year while gross margin changed −50.4 points. So the drop came mostly from the gross margin, which means input costs and prices charged.

Over the last 3 years, 121% of Grupo Aeroportuario del Sureste, S. A. B. de C. V.'s reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in MXN 12.3 B of operating cash against MXN 10.5 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 MXN 7.8 B of spending on assets, MXN 4.5 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.

Grupo Aeroportuario del Sureste, S. A. B. de C. V. 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 MXN 13.6 B on assets over the last 3 years. Averaged over those years that is 12.2% 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: MXN 13.6 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.

Grupo Aeroportuario del Sureste, S. A. B. de C. V.'s P/E is 14.9×, 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.

Grupo Aeroportuario del Sureste, S. A. B. de C. V.'s business is giving mixed signals. There is no clear direction across the growth lines, with ROCE falling at 16.9%; 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.

Grupo Aeroportuario del Sureste, S. A. B. de C. V. earned a ROE of 23% in FY25. That is up from a low of 13% in FY21. Its return on capital used (ROIC) is 9.0 percentage points above its cost of capital, so growth here adds value, not just size.

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.

It comes from a 28.2% net margin and 0.42× asset turnover (sales divided by assets).

Why the return is what it is (FY25): a 28.2% net margin × 0.42× asset turnover × 1.92× leverage (assets divided by equity) ≈ 22.7% on equity. The margin does most of the work; borrowing is a big part of it.

The key test, return on capital used minus the cost of capital: 13.4% − 4.4% = +9.0 percentage points. The 4.4% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. A gap this wide means each dollar put back into the business creates more than a dollar of value.

The 13.4% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 19.7%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method.

Grupo Aeroportuario del Sureste, S. A. B. de C. V. has total debt of MXN 77.8 B against shareholder equity of MXN 51.8 B as of Sep 2026, so its debt is 1.50× its equity. Year by year, that ratio went from 0.30 in FY21 to 0.77 in FY25.

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.

Keep that borrowing in mind when reading the returns on this page.

We have no ownership or short-position figures for Grupo Aeroportuario del Sureste, S. A. B. de C. V., so this section says so rather than fill the gap.
