How AMD Stock Is Valued: What Its P/E and Other Ratios Mean

When a company's value passes a round number, people start asking whether its shares are expensive. The answers come back as numbers that disagree. One website says the stock trades at well over a hundred times its profit, and another, looking at the same price on the same day, says about forty. Both can be right.

A valuation number is always a price divided by something, and that something changes from one source to the next. It can be last year's profit or next year's forecast. It can be profit as the rules require it to be reported, or profit as the company adjusts it. It can also be a year of sales, or the cash the business brought in. Quote the number without knowing which, and two people end up arguing about different things.

Each valuation method answers one question and has one blind spot. Profit-based measures struggle when profit is small for a while, sales-based measures ignore costs, and cash-based measures depend on how much a company chose to invest that year. Looking at two or three together is how analysts avoid being fooled by any single one.

Advanced Micro Devices (AMD), the chipmaker whose market value passed $1 trillion in September 2026, is a sharp example, because its numbers diverge more than most. At its September 25, 2026 close of $630.63, Stock Analysis valued AMD at $1.03 trillion (source: Stock Analysis, AMD statistics). On BloFin, a view on that valuation can be traded through the AMDUSDT Perpetual, a contract that follows AMD's share price.

What is AMD's P/E ratio?

AMD's P/E ratio is its share price divided by its earnings per share over the last 12 months. At the September 25, 2026 close of $630.63, Stock Analysis put it at 160.96 on reported earnings, so buyers paid about $161 for each dollar of a year's profit per share (source: Stock Analysis, AMD statistics).

P/E is short for price-to-earnings. Earnings per share (EPS) is a company's profit for the past 12 months divided by its number of shares (source: Investor.gov, P/E ratio). Market capitalization, or market cap, is the share price multiplied by all the shares outstanding (source: Investor.gov, market capitalization). AMD reported 1,632,475,042 shares outstanding on July 29, 2026 (source: AMD Form 10-Q, Q2 2026).

GuruFocus put the same P/E at 161.82 (source: GuruFocus, AMD forward PE). Worked out on AMD's own adjusted earnings, it is about 109. AMD's adjusted EPS came to $2.73 across the last two quarters of 2025 (source: AMD fourth-quarter and full-year 2025 results). It came to $3.03 across the first and second quarters of 2026, for $5.76 over the four quarters (source: AMD second-quarter 2026 results).

At the same close, Stock Analysis put AMD's enterprise value, which adds debt to the market cap and takes away cash, at $1.02 trillion (source: Stock Analysis, AMD statistics). The common measures of AMD stock at that close work out like this:

The figures differ widely depending on the measure, and the gap between them is useful in itself, because it shows which part of AMD's accounts the price leans on most.

Why AMD's trailing and forward P/E differ between websites

A P/E changes with three choices: which closing price, which earnings and which period. At the same September 25, 2026 close, Stock Analysis put AMD's trailing P/E at 160.96 and its forward P/E at 56.99 (source: Stock Analysis, AMD statistics). GuruFocus, reading the same closing price, showed 161.82 and 40.11 (source: GuruFocus, AMD forward PE).

The trailing figures sit within one point of each other, and neither can be rebuilt exactly from AMD's own reports. AMD earned $0.75 and $0.92 per diluted share in the third and fourth quarters of 2025, or $0.76 and $0.93 per basic share (source: AMD fourth-quarter and full-year 2025 results). In the first and second quarters of 2026, it earned $0.84 and $1.38 diluted, or $0.85 and $1.40 basic (source: AMD second-quarter 2026 results). Over the four quarters that makes $3.89 diluted and $3.94 basic, which work out to P/Es of about 162 and 160. Basic EPS counts only the shares already issued, while diluted EPS also counts the shares that stock options and awards could add. At a ratio this high, a small difference in the earnings or share count a provider uses moves the P/E by a point or two. The forward figures differ by about seventeen points, and with the price the same, that gap comes entirely from the estimated earnings each provider divides by.

AMD itself reports two profit figures in each quarterly report. Reported earnings follow US generally accepted accounting principles, or GAAP. Adjusted, or non-GAAP, earnings leave out items the company treats as outside its day-to-day business, mainly stock-based pay and the gradual expensing of intangible assets bought in past acquisitions, called amortization (source: AMD second-quarter 2026 results).

Add up AMD's last four quarters and the two figures come apart. From the third quarter of 2025 to the second quarter of 2026, reported diluted EPS was $3.89 and adjusted EPS was $5.76. At $630.63, that works out to a P/E of about 162 on reported earnings and about 109 on adjusted earnings. It is the same company, the same price and the same twelve months.

A trailing P/E uses the last four quarters that have been reported. A forward P/E divides the price by the earnings analysts expect for the year ahead (source: CFA Institute, price and enterprise value multiples). The estimates can cover the next 12 months or the next full fiscal year (source: GuruFocus, AMD forward PE). A forward P/E is therefore a reading of analysts' guesses, and those guesses change after every report.

Before you quote any AMD multiple, check four things:

1. The date of the closing price, since a single day's move can shift the ratio by a few points.

2. Whether the earnings are reported or adjusted, which on AMD moves the P/E by about fifty points.

3. Whether it is trailing or forward, which is the difference between last year's profit and a forecast.

4. For a forward figure, whose estimates it uses and over what period.

How a P/E moves when earnings grow or the price changes

A P/E falls when earnings rise faster than the price, and rises when the price outruns earnings. So the same number can tell opposite stories. In early 2026 AMD's P/E fell mainly because its earnings grew, and in the second quarter it about doubled because the share price more than doubled (source: Stock Analysis, AMD quarterly ratios).

Say you see AMD's P/E, which works out to about 162 at the September 25, 2026 close, fall to about 81 a year from now. A drop like that could mean two very different things:

The first is a business that doubled its profit. The second is a share price that halved. The ratio alone cannot tell you which, so check which half of the fraction moved.

Stock Analysis's readings at the end of each fiscal quarter show both effects in AMD's own numbers. Each reading pairs the quarter-end price with the earnings for the four quarters ending that day, which AMD reported a few weeks later. Dividing the market cap by the trailing P/E gives back the four quarters of earnings behind each reading:

In the first quarter of 2026, the market cap fell about 6% while those earnings rose about 15%, so most of the P/E's fall came from the earnings side. In the second quarter, the market cap rose about 158% against earnings growth of about 28%, so the price did the work and the P/E about doubled. Earnings only change when AMD reports, so a P/E steps at each results date and drifts with the price in between. That is why what moves AMD's price from day to day matters as much as the earnings themselves.

AMD's enterprise value and EV/EBITDA

Enterprise value is the price of the whole business: market cap plus debt, minus cash. AMD held more cash than debt at June 27, 2026. Its enterprise value of about $1.02 trillion therefore sat just under its market cap of $1.03 trillion at the September 25, 2026 close (source: Stock Analysis, AMD statistics).

Worked out on AMD's own balance sheet, the sum looks like this:

Stock Analysis shows $1,020.7 billion because it counts $4.3 billion of debt, adding lease obligations to AMD's $3.2 billion of borrowings (source: AMD second-quarter 2026 results). At a company this size, the difference is about 0.1%. These are AMD's June 27, 2026 figures. On August 17, 2026, AMD closed a sale of $4.75 billion of new senior notes, so its borrowings at the September 25 close were higher than this sum shows (source: AMD Form 8-K, August 2026).

Because enterprise value counts debt and cash, a ratio built on it compares companies with different amounts of borrowing more fairly than a P/E does. Analysts often pair it with EBITDA, a profit figure measured before any interest is paid to lenders (source: CFA Institute, price and enterprise value multiples).

EBITDA stands for earnings before interest, tax, depreciation and amortization. It adds back the non-cash charges for wearing out equipment and for gradually expensing intangible assets from past acquisitions. Stock Analysis puts AMD's EBITDA at $9.6 billion for the last four quarters, which gives an EV/EBITDA of 106.74 at the September 25, 2026 close (source: Stock Analysis, AMD statistics).

AMD publishes its own adjusted EBITDA too. It starts from reported profit and adds back further items, which each results release lists, and it came to $5.5 billion across the last two quarters of 2025 (source: AMD fourth-quarter and full-year 2025 results). The first half of 2026 added $6.1 billion, for about $11.5 billion over the same four quarters, which works out to an EV/EBITDA of about 88 (source: AMD second-quarter 2026 results). Providers compute EBITDA in different ways, so compare an EV/EBITDA only with another figure worked out the same way.

AMD's free cash flow and the fabless model

Free cash flow is the cash a business brings in from operations, minus its spending on equipment and buildings. By AMD's own measure it was about $7.7 billion over the four quarters to June 27, 2026. Worked out at the September 25 close, the stock traded at about 133 times that, a yield under 1% (source: AMD second-quarter 2026 results).

In the third quarter of 2025, AMD's free cash flow was $1,530 million (source: AMD fourth-quarter and full-year 2025 results). It reached $2,566 million two quarters later, in the first quarter of 2026. One quarter multiplied by four can therefore miss the year by a wide margin: the second quarter's $1,558 million times four works out to about $6.2 billion, against $7.7 billion over the four quarters (source: AMD second-quarter 2026 results).

Cash flow suits AMD because AMD is fabless: it designs chips and pays other companies to make them. Outside foundries make the silicon wafers for all of AMD's products, and at 7 nanometers and below the foundry for its processors and graphics chips is TSMC (Taiwan Semiconductor Manufacturing Company) (source: AMD Form 10-K, fiscal 2025). Capital spending, the money a company puts into equipment and buildings, is therefore small. It was about 2.8% of revenue in fiscal 2025 (source: AMD Form 10-K, fiscal 2025) and about 4.1% over the last four quarters (source: AMD second-quarter 2026 results).

Stock Analysis shows a higher figure, $8.4 billion. Its operating cash flow includes cash from a business AMD sold and now reports as discontinued operations, while AMD's own measure counts only the business it kept (source: AMD Form 10-K, fiscal 2025). Because AMD pays no dividend, analysts often use free cash flow as the return the company generates for its owners (source: CFA Institute, free cash flow valuation).

Free cash flow measures one year's cash, and AMD has signed up for large payments ahead. At June 27, 2026, it had about $30.3 billion of unconditional commitments, mainly to buy wafers, substrates and components and to pay for cloud capacity. After that date it agreed to investment commitments of up to $5.0 billion through fiscal 2028. It also signed data-center leases with $9.5 billion of future payments, starting in 2027 and 2028 (source: AMD Form 10-Q, Q2 2026). Much of the wafer spending goes to one supplier, which is why AMD's reliance on TSMC matters to any cash-flow view.

Price-to-sales and PEG for a fast-growing AMD

Price-to-sales divides market value by a year of revenue, so it works even when profit is small. AMD's was 24.92 at the September 25, 2026 close (source: Stock Analysis, AMD statistics). PEG, the price/earnings-to-growth ratio, divides the P/E by expected earnings growth, to test whether growth pays for the multiple (source: CFA Institute, price and enterprise value multiples).

Sales are harder to distort than earnings and are never negative, which makes price-to-sales useful for a company whose profit swings. Its blind spot is cost. Two companies with the same sales can keep very different amounts as profit, and price-to-sales treats them the same. A high price-to-sales for AMD assumes its profit margins widen as it grows, a bet that rests on AMD's AI growth story.

Stock Analysis, for one, prints a PEG ratio for AMD without saying which growth estimate it uses, so the figure cannot be checked (source: Stock Analysis, AMD statistics). Working the PEG from a stated growth figure shows what it measures. At its Financial Analyst Day on November 11, 2025, AMD set a target of adjusted EPS above $20 within three to five years (source: AMD Financial Analyst Day, November 11, 2025). Its adjusted EPS for fiscal 2025 was $4.17 (source: AMD fourth-quarter and full-year 2025 results). That is management's target, and it may not be met.

Say you take that target at face value. Going from $4.17 to $20 sets the yearly growth below, and dividing AMD's adjusted P/E of about 109 at the September 25, 2026 close by that growth gives the PEG:

The CFA Institute's rule is simple: all else equal, a lower PEG is more attractive than a higher one (source: CFA Institute, price and enterprise value multiples). Even on management's own target, AMD's PEG sits above 1.5.

Discounted cash flow: What AMD's price implies

A discounted cash flow model values a company as today's worth of all its future cash (source: CFA Institute, free cash flow valuation). Run backward, it shows what growth a price assumes. For AMD at the September 25, 2026 close, that works out to about 9% a year forever at a 10% discount rate.

The discount rate is the yearly return an investor demands for waiting and for taking risk. The CFA Institute's constant-growth formula sets a company's value equal to next year's free cash flow divided by the discount rate minus the growth rate:

Value = next year's free cash flow ÷ (discount rate − growth rate)

Solve it for the growth rate using two AMD figures: its enterprise value of about $1,019.6 billion at the September 25, 2026 close, and its free cash flow of about $7.7 billion over the four quarters to June 27, 2026. The result is the growth the price implies at each discount rate:

At a free cash flow yield under 1%, the implied growth sits within about a point of whatever discount rate you choose. The answer depends heavily on that one input. Published valuations of AMD in late September 2026 ranged widely. A Simply Wall St cash-flow model published on September 23 sat close to the $623.77 share price it quoted (source: Simply Wall St, September 23, 2026). GuruFocus's own GF Value put AMD at under half of its $630.63 close on September 25 (source: GuruFocus, AMD forward PE).

A constant-growth model is a simplification. Analysts valuing a company growing this fast usually model a fast stage followed by a slower one. The reverse calculation is still useful, because it turns a price into a growth rate you can argue with.

AMD's valuation against its history and its peers

At the September 25, 2026 close, AMD traded above every fiscal year-end since 2021 on forward P/E, EV/sales and EV/EBITDA (source: Stock Analysis, AMD financial ratios). Against Nvidia and Intel at the same close, it was the most expensive of the three on trailing earnings and on EV/EBITDA.

The history shows how far the 2026 run stretched every measure at once. EV/EBITDA rose from 51.39 at the end of fiscal 2025 to 106.74, about 55 points, more than it had moved between any two year-ends before it (source: Stock Analysis, AMD financial ratios).

Nvidia earned far more for each dollar of its share price: its trailing P/E of 28.46 was less than a fifth of AMD's, the widest gap between Nvidia and AMD stock on any of the five measures (source: Stock Analysis, NVIDIA statistics). Intel reported a loss over the last year, which leaves Intel's stock against AMD's with no trailing P/E to compare. At 228.30 times free cash flow, Intel was the most expensive of the three on that measure (source: Stock Analysis, Intel statistics).

Comparing AMD's valuation methods

The P/E asks how much profit you pay for, and price-to-sales how much revenue. EV/EBITDA asks what the whole business earns before financing, and free cash flow how much cash arrives. PEG tests whether growth covers the multiple, while a discounted cash flow shows what the price assumes. On AMD they disagree most when profit is low.

Fiscal 2023 shows why no single method is enough. That year AMD's EV/EBIT, which divides enterprise value by operating profit after amortization, stood at 586.58. Its EV/EBITDA was 61.03 and its EV/sales 10.37 (source: Stock Analysis, AMD financial ratios). That year AMD booked $2.8 billion of amortization of acquisition-related intangibles against operating income of $401 million, after recording large intangible assets from its Xilinx and Pensando acquisitions (source: AMD Form 10-K, fiscal 2023). On operating profit AMD looked wildly expensive, at almost ten times its EV/EBITDA, while its EV/sales was in line with fiscal 2021 and fiscal 2025.

Reading several measures together is what lets you tell a small-profit year from an expensive share price. The same habit applies in 2026, when reported and adjusted P/Es sit about fifty points apart. The ratios describe the price, and deciding whether AMD is a good investment still means setting that price against the risks to AMD's growth.

Trading a view on AMD's valuation on BloFin

BloFin lists the AMD perpetual, which moves with AMD's share price, settles in USDT and offers leverage of up to 20x (source: BloFin, AMDUSDT contract information). A view that AMD is too cheap or too expensive can be taken long or short on it, without owning any shares.

BloFin began trading the AMDUSDT Perpetual on May 6, 2026, with trading hours listed as 24/7 (source: BloFin listing notice). Nasdaq's regular session runs from 9:30 a.m. to 4 p.m. New York time (source: Nasdaq, stock market schedule). Outside it, and on weekends and exchange holidays, BloFin may limit trading in its stock futures to reduce-only orders, which can only shrink or close a position (source: BloFin stock futures notice). A P/E worked out at a Friday close is a reading at one moment, and the contract keeps trading before Nasdaq opens again.

Valuation is a slow argument, while funding on the AMDUSDT Perpetual is paid or received every eight hours (source: BloFin, AMDUSDT contract information). A position held for months therefore carries a running cost or credit that shares never do, which holding the perpetual long term sets against owning the stock. A view that AMD is too expensive is a short, and on the perpetual shorting AMD on BloFin takes a sell order, and the short gains as the price falls.

Leverage also shortens the time a valuation view has to be right. Say you judge AMD too expensive and short 100 contracts at $630, which is one AMD share's worth, since each contract is 0.01 of a share (source: BloFin listing notice). At 10x leverage you put up about $63 of margin, so a rise of about 10% would use all of it, worked out before fees. Maintenance margin is the least margin a position needs to stay open. BloFin may cut the position in part or liquidate it sooner, once your margin falls to that level plus the fee for closing it (source: BloFin liquidation rules). A price that later proves your valuation right does nothing for a position already closed.

Frequently asked questions

What is AMD's earnings yield?

AMD's earnings yield was 0.62% at the September 25, 2026 close, against 1.24% at the end of fiscal 2025 (source: Stock Analysis, AMD financial ratios). Earnings yield turns the P/E upside down: it is a year's earnings divided by the share price, so it shows how much profit each dollar of the price buys. Each dollar of AMD therefore bought about half as much profit as nine months earlier, and whether that is enough depends on how fast AMD's profit grows from here.

What is AMD's price-to-book ratio?

AMD's price-to-book ratio was 15.31 at the September 25, 2026 close, up from 5.56 at the end of fiscal 2025 (source: Stock Analysis, AMD financial ratios). Book value is shareholders' equity, the assets on the balance sheet minus all its liabilities, and AMD's stood at $67.2 billion (source: Stock Analysis, AMD statistics). Price-to-tangible-book, which also removes goodwill and other intangible assets left by acquisitions such as Xilinx, was 39.42, so most of AMD's book value was paid for in past deals.

Why is AMD's forward P/E so high?

A forward P/E moves with both the price and the analysts' estimates, and in 2026 the price moved faster. GuruFocus's own quarter-end readings put AMD's forward P/E at 30.32 at the end of March 2026 and 70.54 at the end of June 2026, as the share price more than doubled (source: GuruFocus, AMD forward PE). Estimates usually rise after a strong report, which can pull the forward P/E back down even while the price holds.

How much debt does AMD have?

AMD had five senior notes outstanding at June 27, 2026, with a total principal of $3.25 billion, due between 2026 and 2052 at interest rates from 2.375% to 4.393% (source: AMD Form 10-Q, Q2 2026). The largest, $875 million at 4.212%, matured on September 24, 2026 (source: AMD Form 8-K, March 2025, Exhibit 4.1). On August 17, 2026, AMD added $4.75 billion of new senior notes, due in 2029, 2031, 2033 and 2036 (source: AMD Form 8-K, August 2026). At June 27, 2026, its cash and short-term investments of $13.1 billion were about four times the notes then outstanding (source: AMD Form 10-Q, Q2 2026).

How does AMD's share count affect its P/E?

A P/E divides the share price by earnings per share, so the number of shares matters as much as the profit. AMD's share count rose 1.07% over the year to September 2026 (source: Stock Analysis, AMD statistics). It rises because AMD issues shares to employees under its stock plans (source: AMD Form 10-Q, Q2 2026). With profit unchanged, 1.07% more shares cut earnings per share by about 1.1% and lift the P/E by the same proportion, which at a P/E near 161 is about 1.7 points.
