What does Atlas Copco AB (ATLKY) do?

Atlas Copco AB, founded in Stockholm in 1873, makes the machinery that keeps factories running. It reports four business areas. Compressor Technique, the largest, sells industrial air and gas compressors, dryers and blowers. Vacuum Technique, built around brands like Edwards and Leybold, supplies the vacuum pumps and abatement systems that semiconductor fabs, flat-panel lines and scientific labs depend on. Industrial Technique sells precision tightening tools, assembly systems and machine vision, much of it to car makers. Power Technique rents and sells portable compressors, generators, pumps and lighting. A large share of revenue comes from service, spare parts and rentals on an enormous installed base, which smooths results through the cycle. ATLKY is a sponsored Citibank ADR where one ADR equals one A share traded in Stockholm as ATCO A, so ADR prices and dividends move with both the Swedish share and the krona to dollar exchange rate.

The last two years were a slowdown, not a crisis. Full-year 2025 revenue fell in reported terms, hit by a strong krona, and diluted earnings per share slipped to about SEK 5.42 from SEK 6.10 in 2024. Then orders turned sharply. In the second quarter of 2026 order intake jumped 27% to about SEK 51.0 billion, 26% organically, with double-digit gains in every business area and vacuum equipment leading as chipmakers restarted fab investment. Revenue reached about SEK 45.0 billion with 8% organic growth, and the adjusted operating margin was 21.0%. Trailing twelve-month revenue is roughly SEK 170 billion, about $17 to $18 billion. The investment picture comes down to whether that order surge converts into revenue and margin expansion in late 2026 and 2027. Management's guidance is cautious, saying it expects customer activity to stay at current levels, and the third-quarter report is due on October 22, 2026. At around 38 times trailing earnings and about 30 times forward estimates, with a market value near $100 billion, Atlas Copco is priced as one of the best industrials in the world.

What's driving Atlas Copco AB (ATLKY)?

1. Semiconductor vacuum recovery

Vacuum Technique is the most cyclical and most exciting part of the group. Every advanced chip fab needs large numbers of dry pumps, turbomolecular pumps and exhaust abatement systems, and Atlas Copco, through Edwards and Leybold, is one of the two or three leading suppliers. Semiconductor customers slowed orders through much of 2024 and 2025 as memory and mature-node investment paused. The second quarter of 2026 changed that, with vacuum equipment named as the main driver of 26% organic order growth for the group. AI data center demand is pushing spending on advanced logic and high-bandwidth memory, which use more vacuum content per wafer. If fab construction in the US, Taiwan, Korea and Japan keeps its current pace, this division could lift group growth and margins through 2027. If chip capex pauses again, it is also where a slowdown would show first.

2. Compressor service and energy efficiency

Compressor Technique is the steady engine of the group. Compressed air can consume 10% or more of a factory's electricity, so variable-speed, energy-efficient compressors pay back quickly when power prices are high and when companies have decarbonization targets. Atlas Copco has spent years pushing its variable-speed drive designs and connected monitoring, which lets it sell service contracts tied to uptime. Service and aftermarket revenue makes up a large share of the division and tends to grow even when new equipment orders soften, because the installed base keeps running and needs parts, filters and overhauls. This recurring layer is a major reason group operating margins stayed near 20% through the 2025 slowdown, when reported revenue fell. Growth here depends on general manufacturing activity, which has been mixed, but the margin floor is a big part of the investment case.

3. Acquisition machine

Atlas Copco is a serial acquirer, typically buying 20 to 30 small and mid-sized companies a year, often regional compressor distributors, service businesses, niche pump makers and specialty vacuum firms. The company's strong balance sheet and cash generation, with operating cash flow measured in the tens of billions of krona a year, let it keep buying through downturns when sellers are cheaper. The model works because Atlas Copco runs a highly decentralized structure, letting acquired businesses keep their brands while plugging into group purchasing and service. The risk is that acquired growth can mask weaker organic trends, so investors usually watch the organic order number in each quarterly report rather than the reported total.

4. Margins, cash returns and currency

Atlas Copco targets returns well above its cost of capital and has historically delivered return on capital employed in the high 20s percent. The adjusted operating margin of about 21% in the second quarter of 2026 compares well with most industrial peers, which tend to run in the mid-teens. For 2025 the board proposed SEK 5.00 per share, a SEK 3.00 ordinary dividend plus a SEK 2.00 extra distribution, paid in two installments, which works out to roughly $0.50 per ADR at recent exchange rates before Swedish withholding tax. Currency is a meaningful swing factor. Atlas Copco reports in krona but earns most of its money abroad, so a strong krona shrinks reported numbers, as it did in 2025. For ATLKY holders, a stronger krona against the dollar can offset some of that drag because the ADR is priced in dollars.

What are the risks to Atlas Copco AB (ATLKY)?

Valuation is the most immediate risk. At roughly 38 times trailing earnings and about 30 times forward estimates, Atlas Copco trades at a large premium to most industrial peers, and premium multiples can compress quickly if growth disappoints. The recent order surge is heavily tied to semiconductor customers, and chip capital spending is famously lumpy, so a pause in fab projects could reverse vacuum orders within a few quarters. General industrial demand in Europe and China has been soft, and Industrial Technique depends on automotive production, where electric vehicle investment has slowed. Currency moves cut both ways: a strong krona reduces reported revenue and earnings, while ATLKY holders also carry the krona to dollar exchange rate directly. Tariffs and trade restrictions, including US export controls on semiconductor equipment to China, could affect both demand and supply chains. Its frequent acquisitions bring integration risk and can make organic trends harder to read. ATLKY trades over the counter, so spreads can be wider and liquidity thinner than for the Stockholm shares, and dividends are subject to Swedish withholding tax, which some US investors can only partially reclaim.

Is ATLKY a buy or a sell?

We give no verdict on Atlas Copco AB. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Semiconductor vacuum recovery. Vacuum Technique is the most cyclical and most exciting part of the group.

The case against. Valuation is the most immediate risk.

How is Atlas Copco AB (ATLKY) valued? (approximate, October 2026)

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Atlas Copco AB's investor relations page or your broker.

  • Revenue (TTM): ~SEK 170B (~$17-18B)
  • Adjusted operating margin (Q2 2026): ~21.0%
  • Diluted EPS (TTM): ~SEK 5.46 (~$0.55 per ADR)
  • Trailing P/E: ~38x
  • Market cap: ~$100B
  • Dividend for 2025: SEK 5.00 incl. SEK 2.00 extra (~$0.50 per ADR)

Figures reflect results through the second quarter of 2026, with the third-quarter report due October 22, 2026. Because one ATLKY ADR equals one Stockholm A share, per-ADR earnings and dividends are the krona figures converted at roughly 9.5 to 10 krona per dollar, so they shift with the exchange rate. The trailing multiple looks expensive partly because 2025 earnings were depressed by a strong krona and a cyclical dip; on forward consensus the P/E is closer to 30 times. Even so, that is well above typical industrial multiples, reflecting Atlas Copco's margins, service mix and long record of high returns on capital.

FAQ

What is ATLKY?

+

ATLKY is a sponsored American depositary receipt for the A shares of Atlas Copco AB, the Swedish industrial group. Each ADR represents one A share listed on Nasdaq Stockholm under ATCO A, and Citibank acts as depositary. The program has existed in the US since 1990. Because it trades over the counter rather than on the NYSE or Nasdaq, it is available through most US brokers but can have wider bid-ask spreads and lower volume than the home listing. There is also a second ADR, ATLCY, which tracks the B shares; B shares carry fewer votes and usually trade at a slight discount to A shares. The ADR price reflects two things at once: the krona price of the Stockholm shares and the krona to dollar exchange rate.

What does Atlas Copco actually make?

+

Atlas Copco makes equipment that factories, chip fabs and construction sites use every day, and then services it for decades. Compressor Technique sells industrial air and gas compressors, blowers and dryers, from small units for workshops to huge machines for process plants. Vacuum Technique, through the Edwards and Leybold brands, supplies the vacuum pumps and gas abatement systems used in semiconductor manufacturing, displays, solar and research. Industrial Technique sells precision electric tightening tools, assembly systems, adhesive dispensing and machine vision, with car makers as major customers. Power Technique offers portable compressors, generators, dewatering pumps and lighting towers, plus a rental business. Across all four areas, service, spare parts and rentals on a very large installed base provide a recurring revenue stream that makes the group less cyclical than its customer industries.

How did Atlas Copco perform in 2026 so far?

+

After a slower 2025, when reported revenue declined and diluted earnings per share slipped to about SEK 5.42, 2026 brought a sharp turn in orders. First-quarter orders were about SEK 45.4 billion, up 5% organically, while revenue of about SEK 40.5 billion grew 3% organically. The second quarter was the standout: orders jumped 27% to roughly SEK 51.0 billion, up 26% organically, with double-digit order growth in every business area and vacuum equipment for semiconductors leading. Revenue rose 8% organically to about SEK 45.0 billion, and the adjusted operating margin improved to 21.0% from 20.4% a year earlier. The third-quarter report, scheduled for October 22, 2026, will show whether that momentum continued.

Is ATLKY expensive?

+

By most measures, yes, relative to industrial peers. Based on trailing diluted earnings of about SEK 5.46 per share, the shares traded near 38 times earnings in recent months, and around 30 times forward consensus estimates. The premium reflects Atlas Copco's operating margins near 21%, a large and steady service business, returns on capital that have historically been among the best in the sector, and exposure to semiconductor vacuum demand, which investors see as a long-term growth market. The trailing multiple is also inflated somewhat by 2025 earnings, which were held back by a strong krona and a cyclical dip. Whether the valuation holds depends heavily on whether the 2026 order rebound turns into higher revenue and profit in 2027, so the stock can react strongly to quarterly order numbers.

Does ATLKY pay a dividend?

+

Yes. Atlas Copco pays dividends in Swedish krona, and Citibank passes them through to ADR holders in dollars after fees and taxes. For fiscal 2025, the board proposed SEK 5.00 per share, made up of a SEK 3.00 ordinary dividend and a SEK 2.00 extra distribution, paid in two equal installments during 2026. Because one ADR equals one share, that is roughly $0.50 per ADR at recent exchange rates, though the exact dollar amount depends on the rate on the payment date. Sweden withholds tax on dividends paid to foreign holders, nominally 30%, with the US treaty rate at 15%; getting the treaty rate can require paperwork, and US investors may be able to claim a foreign tax credit. The trailing yield has been modest, around 1.5% to 2.5% depending on whether extra distributions are counted, because the share price is high relative to earnings.

Why does semiconductor demand matter so much for Atlas Copco?

+

Vacuum Technique is the business area most tied to chipmaking, and it is also the one that swings most with the cycle. Semiconductor fabs need large numbers of vacuum pumps on deposition, etching and lithography tools, plus abatement systems that neutralize toxic process gases. More advanced chips, including the logic and high-bandwidth memory used in AI servers, require more process steps and more vacuum content per wafer. When chipmakers cut capital spending in 2024 and 2025, vacuum orders fell, which weighed on the group. When spending restarted in 2026, vacuum led the 26% organic order jump in the second quarter. The flip side is that chip capex is lumpy, so this division can turn from tailwind to headwind within a few quarters.

How does currency affect ATLKY holders?

+

Currency matters at two levels. First, Atlas Copco reports in Swedish krona but earns the large majority of its revenue outside Sweden, in dollars, euros, yuan and other currencies. When the krona strengthens, those foreign earnings translate into fewer krona, which is a big reason reported revenue and earnings fell in 2025 even though organic trends were roughly flat to positive. Second, ATLKY itself is priced in dollars, so its value moves with the krona to dollar rate. A stronger krona lowers reported results but raises the dollar value of each ADR, and a weaker krona does the reverse, which partly offsets the effect for US holders. Dividends are declared in krona and converted to dollars, so the dollar payout also changes with the exchange rate.

Who runs Atlas Copco and how is it owned?

+

Atlas Copco is led by President and CEO Vagner Rego, a long-time company executive who took the top job in 2024 after running the Compressor Technique business area. The largest shareholder is Investor AB, the Wallenberg family's holding company, which controls a significant share of the votes through its A share stake and has backed the group for generations. That stable ownership is often cited as a reason Atlas Copco can take a long-term view, keep investing through downturns and pursue steady acquisitions. The company has a history of portfolio reshaping, including spinning off mining equipment maker Epiroc in 2018 to sharpen its focus on industrial equipment. Atlas Copco is not under any announced takeover, and its shares trade on their own fundamentals rather than tracking an offer price.
