Valuation history

Is AMT or SPG more expensive against its earnings, sales and book value?

→On the latest figures, AMT's price to earnings is 26.0x, against 15.0x at SPG.

What this measures

What the market has paid for each dollar of earnings, sales or book value, every year, with today's multiple as the last point and the median drawn across.

What good looks like. There is no good level. What matters is the distance from the company's own history, and whether the business has changed enough to justify it.

If it rises or falls. A multiple above its own median means the market expects more than it used to, so more has to go right. Below the median means the opposite, and the question is whether the pessimism is deserved. A multiple can also fall because earnings rose, which is the good way.

Enterprise value

How do AMT and SPG compare on EV/EBITDA, debt included?

→On the latest figures, AMT's EV/EBITDA is 20.6x, against 19.4x at SPG.

What this measures

Enterprise value over EBITDA. Enterprise value is the market value of the equity plus debt, less cash and short-term investments - what it would cost to buy the whole company outright. EBITDA is operating profit before depreciation and amortisation.

What good looks like. A multiple below what similar businesses change hands at, and one that has not run far above the company's own past.

If it rises or falls. It rises when the price rises or profit falls, and debt moves it too: two companies on the same price-to-earnings can sit far apart here if one is carrying borrowings the other is not.

What does “Value” actually mean?

Value asks what you pay for each dollar of earnings, sales or cash a business produces. A high multiple is not automatically bad, since fast growers can earn theirs, but a price far above a company's own history means the market expects a lot to go right. Each company is measured against its own past and its sector.

Revenue history

Is AMT or SPG growing revenue faster?

→On the latest figures, AMT's revenue is $10.9B, against $6.9B at SPG.

What this measures

The money customers paid, before any costs are taken out. Each bar is one quarter or, on the annual view, a full financial year; the last annual bar may be the trailing twelve months, which the footnote marks.

What good looks like. Growth that repeats, rather than one strong year carrying the chart, and a trailing twelve months keeping pace with the last full year.

If it rises or falls. Revenue is the hardest line to flatter, so a rise is the most trustworthy kind of growth. A fall puts pressure on every margin below it, because costs rarely come down as quickly as sales do.

Profit history

Is AMT or SPG growing its net profit faster?

→AMT's latest net profit is $3.4B (2026), against $4.6B at SPG (2025).

What this measures

What is left after every cost, including tax and interest. The bottom line of the income statement.

What good looks like. Profit growing at least as fast as revenue, which means the business is keeping more of each sale as it gets bigger.

If it rises or falls. Profit can move for reasons revenue cannot explain - a one-off charge, a tax change, a write-down - so a single sharp year is worth checking against the margin chart before reading it as a trend.

Growth rate

How fast is revenue growing at AMT and at SPG?

→On the latest figures, AMT's revenue growth is 6.6%, against 15.0% at SPG.

What this measures

How much revenue and earnings changed against the year before - the trailing twelve months against the twelve before them at each quarter, or one point per fiscal year. It is the speed of the business, not its size.

What good looks like. The earnings line above the revenue line: profits growing faster than sales means each new dollar of sales arrives more profitably than the last.

If it rises or falls. A high growth rate off a small base is easy and gets harder every year, so slowing growth in a large business is normal rather than a warning. Earnings falling while revenue grows is the combination worth understanding: costs are rising faster than sales.

Per-share growth

Is revenue per share growing faster at AMT or SPG?

→On the latest figures, AMT's revenue per share is $23.47, against $21.42 at SPG.

What this measures

Revenue and free cash flow, each divided by the number of shares in issue and adjusted for splits so old and new years compare honestly. Both lines rising means each share owns more of the business's sales and cash.

What good looks like. Both lines rising, and revenue per share growing at least as fast as the company's total revenue, which the answer compares. Faster means buybacks are working for you; slower means new shares are absorbing part of the growth.

If it rises or falls. This is the line that actually reaches you. A company can grow revenue every year and still shrink your slice by issuing shares faster than it grows.

What does “Growth” actually mean?

Growth here is what each company has reported to the SEC, not a forecast: the last year, the three-year pace, and whether growth is speeding up or slowing down. Both companies are measured the same way, so their lines can be read against each other.

Margins

Which keeps more of each sale as profit, AMT or SPG?

→On the latest figures, AMT's operating margin is 44.8%, against 47.4% at SPG.

What this measures

What survives at three points on the way down the income statement: after the direct cost of the product, after the cost of running the company, and after everything.

What good looks like. Margins that hold or widen as the business grows. The level itself varies enormously by industry, so the shape over time tells you more than the number.

If it rises or falls. A widening margin means pricing power or costs under control. A compressing one means the opposite, and it compounds: on large revenue, two points of margin is a great deal of profit.

Earnings quality

Does profit turn into cash better at AMT or SPG?

→On the latest figures, AMT's operating cash per dollar of profit is 2.2x, against 0.9x at SPG.

What this measures

Reported profit against the cash the business actually collected from operating. Profit is an accounting judgement; cash is not.

What good looks like. Cash at or above profit, year after year. Depreciation and other non-cash charges usually push cash above profit, so roughly 100% or more is healthy.

If it rises or falls. Cash falling behind profit for more than a year is the classic early warning: the sales are booked but the money has not arrived, and it shows up in receivables and inventory. For a lender the comparison behaves differently, because a growing loan book consumes cash.

Returns on capital

Which earns a higher return on its capital, AMT or SPG?

→On the latest figures, AMT's return on equity is 91.6%, against 119.6% at SPG.

What this measures

Two returns side by side: on shareholders' capital (ROE), and on all the capital in the business including debt (ROCE).

What good looks like. Both comfortably above roughly 10%, and close together. A wide gap means borrowing, not operations, is doing the work.

If it rises or falls. A high ROE built on debt looks like quality until the debt has to be refinanced. ROCE is the harder number to flatter, which is why both are shown.

Funds from operations

How much funds from operations do AMT and SPG earn?

→On the latest figures, AMT's funds from operations is $3.6B, against $6.1B at SPG.

What this measures

Net income with property depreciation added back, the measure REIT investors use instead of earnings.

What good looks like. FFO per share growing steadily, since that is what funds the dividend.

If it rises or falls. Depreciation assumes buildings wear out, which well-maintained property largely does not, so reported earnings understate what a REIT collects. FFO corrects for that, which is why it is the number the sector is judged on.

What does “Quality” actually mean?

Quality asks whether growth turns into real money: how much of each sale is kept as profit, whether that profit arrives as cash, and what return the business earns on the money invested in it.

Debt & cash

How much debt do AMT and SPG carry, against the cash they hold?

→On the latest figures, AMT's total debt is $37.2B, against $28.7B at SPG.

What this measures

Total borrowings against cash on hand, with debt as a multiple of shareholders' equity, and how many times profit covers the interest bill.

What good looks like. Interest covered comfortably - roughly eight times or more - and debt that is not a large multiple of equity.

If it rises or falls. Debt is only a problem when it has to be repaid or refinanced in a bad year, so cover matters more than the amount. Rising debt with rising cover is a business borrowing to grow; rising debt with falling cover is the combination that ends badly.

Interest cover

How many times over can AMT and SPG pay their interest bills?

→On the latest figures, AMT's interest cover is 3.5x, against 3.1x at SPG.

What this measures

Operating profit divided by interest expense - how many times over the year's earnings could pay the year's interest.

What good looks like. High and steady. Five times is a common floor; comfortably above it means the debt is being carried, not merely serviced.

If it rises or falls. It falls when profit falls or when borrowing costs rise, and a company can look safe on the level while the direction is telling you otherwise.

Cash conversion

Which turns more of its revenue into operating cash, AMT or SPG?

→On the latest figures, AMT's operating cash margin is 52.8%, against 59.4% at SPG.

What this measures

Operating cash flow as a share of revenue: of every dollar sold, how much reached the bank before capital spending.

What good looks like. A high share, holding up or improving. It is the clearest sign that reported profit is real.

If it rises or falls. It falls when customers take longer to pay or stock builds up, and it can stay high while profit falls - which is usually the more reassuring of the two.

Shareholders' equity

Is shareholders' equity growing faster at AMT or SPG?

→On the latest figures, AMT's shareholders' equity is $3.7B, against $4.4B at SPG.

What this measures

What would be left for shareholders if every asset were sold at its book value and every debt repaid. Book value, in other words.

What good looks like. Equity growing as retained profits build up, unless the company is deliberately returning more than it earns.

If it rises or falls. Equity falls for two very different reasons: buybacks, which return money to you, and losses, which do not. The distinction is the whole story, and negative equity means liabilities now exceed assets, which makes debt-to-equity and return on equity meaningless rather than alarming.

What does “Financial health” actually mean?

Financial health asks one question: could the business get through a bad year? It looks at how much each company has borrowed, how easily its profits cover the interest, and how much cash it holds against the bills due soon.

Shareholder returns: AMT vs SPG

AMT5/6SPG5/6

Both pay dividends, and Simon Property Group has the higher yield, 4.3% against 3.8%. A yield also rises when a share price falls, so it reads best beside how much of its profit each pays out.

Capital returned

How much cash do AMT and SPG hand back to shareholders?

→On the latest figures, AMT's cash returned in dividends and buybacks is $3.5B, against $227M at SPG.

What this measures

Cash returned through buybacks and dividends, alongside the value of new shares issued to employees as compensation.

What good looks like. Returns comfortably larger than stock compensation, so the share count actually falls.

If it rises or falls. A company can announce billions in buybacks while issuing nearly as much stock to staff, and the two largely cancel. What reaches you is the net effect, which is why both bars are here rather than only the buyback.

Shareholder yield

Which pays shareholders the higher yield, AMT or SPG, counting buybacks?

→On the latest figures, AMT's shareholder yield is 4.0%, against 0.4% at SPG.

What this measures

Dividends and buybacks, each as a percentage of what the company was worth that year. The dollar chart says how much came back; this says how much came back for the price.

What good looks like. A total that clears a couple of percent and holds. Which half it comes from matters less than whether it is sustained.

If it rises or falls. A yield rises when the price falls as readily as when the payout grows, so read a jump beside the price chart before treating it as generosity.

Share count change

Is the share count falling faster at AMT or SPG?

→On the latest figures, AMT's change in share count is -0.5%, against -0.8% at SPG.

What this measures

The yearly change in the number of shares in issue, adjusted for splits so the years compare. A bar below zero is a falling share count, usually from buybacks; above zero, new shares were issued.

What good looks like. A flat or falling share count. Falling means each share you hold owns a little more of the business every year.

If it rises or falls. A rising count divides the same business among more owners, so your slice shrinks unless profits grow faster. This is the most direct chart on the page: it is your ownership, measured.

Dividend per share

Is the dividend per share growing faster at AMT or SPG?

→AMT's latest dividend per share is $6.79 (2025), against $7.91 at SPG (2018).

What this measures

The dividend paid on one share each year, adjusted for splits so a share today compares with a share ten years ago.

What good looks like. A payment that rises steadily. A long unbroken run of rises is a management commitment as much as a number.

If it rises or falls. A cut is one of the strongest signals a board can send, because they know how it will be read. Check it against the payout chart: a rising dividend the business cannot cover is a promise borrowed against.

Dividend yield

Which pays the higher dividend yield, AMT or SPG?

→AMT's latest dividend yield is 3.6% (2025), against 7.3% at SPG (2018).

What this measures

The dividend paid over the trailing twelve months as a percentage of the share price, at each quarter's (or year's) average price and at today's.

What good looks like. A yield in line with the company's own history. A yield far above it is usually the price falling, not the dividend rising.

If it rises or falls. Yield moves for two opposite reasons, and they are easy to confuse: a bigger dividend, or a cheaper share. The dividend-per-share chart above tells you which one happened.

Payout quality

How much of their profit do AMT and SPG pay out as dividends?

→AMT's latest share of profit paid as dividends is 125.7% (2025), against 100.5% at SPG (2018).

What this measures

The dividend as a share of profit, and as a share of free cash flow. Two views of the same question, because profit and cash are not the same thing.

What good looks like. Comfortably under 75% of profit and under 90% of free cash flow, which leaves room to keep paying through a weak year.

If it rises or falls. A payout ratio climbing towards 100% means the dividend is consuming everything the business earns, so the next bad year has to be funded by borrowing or by a cut. Above 100% it is already being funded from somewhere else.

What does “Shareholder returns” actually mean?

Shareholder returns is the cash a company hands back to the people who own its shares, through dividends and by buying its own shares back, and whether the stock it issues to staff quietly undoes those buybacks.
