Who owns ABB? Ownership structure explained (2026)

ABB is one of Europe's largest industrial technology groups. It makes the circuit breakers, switchgear, motors, drives, and control systems that sit inside factories, ports, rail networks, and data centers. Most people never see its products, but a large share of the world's electrical infrastructure runs through them.

Its ownership is a product of that history. ABB is the child of a Swedish company and a Swiss one, and the Swedish side's anchor owner never left. Nearly four decades after the merger, the Wallenberg family's investment company still holds the biggest single stake and places two directors on the board. The rest of the register is spread across global funds and retail investors in Switzerland and Sweden.

That structure matters now more than usual. ABB is in the middle of reshaping itself: it agreed in October 2025 to sell its Robotics division to SoftBank Group, it is buying back shares, and its electrification business is riding demand from AI data centers. This article explains who owns ABB, how that ownership came together, and who actually steers the company.

ABB traces its roots to two 19th-century engineering firms. ASEA was founded in Sweden in 1883 by Ludvig Fredholm. Brown, Boveri & Cie was founded in Baden, near Zurich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri. The two agreed to merge in August 1987, and the combined company, Asea Brown Boveri, began operating in January 1988 with each parent holding 50%.

Today ABB is headquartered in Zurich and employs around 110,000 people. It organizes its business into three areas: Electrification, which sells low- and medium-voltage power products; Motion, which sells motors, drives, and rail traction equipment; and Automation, which covers process control systems for industries such as energy, marine, and ports, plus machine automation. Robotics sat inside a fourth business area, Robotics & Discrete Automation, until ABB agreed to sell the Robotics division and folded the remaining Machine Automation division into Automation.

The company is posting record numbers. In 2025, ABB reported orders of $36.8 billion, revenue of $33.2 billion, and net income attributable to shareholders of $4.73 billion, with an operational EBITA margin of 19.0%. In the second quarter of 2026, orders hit a new high of $12.0 billion on revenue of $9.5 billion, and the operational EBITA margin reached 20.2%. Data centers led demand growth in Electrification in late 2025, and ABB is working with Nvidia on 800-volt direct current power architecture for next-generation AI facilities.

ABB Ltd is a Swiss-incorporated public company. No person or company controls it, and there is no parent above it. Its shares trade in Zurich and Stockholm, and roughly 1.8 billion shares are outstanding, based on Investor AB's disclosed share count and stake. ABB discloses any holder that crosses Swiss thresholds of 3%, 5%, 10%, 15%, and higher, so the list of named owners is short.

ABB has no founder shareholders in the usual sense. Its founders, Fredholm, Brown, and Boveri, lived in the 1800s, and no founding family holds a disclosed stake. The closest thing to a founding-era owner is Investor AB. The Wallenberg sphere, which set up Investor in 1916, built up its ownership in ASEA in the years that followed, and that link carried over into ABB at the 1988 merger.

The table below lists every shareholder ABB currently discloses above the 3% threshold. Each figure reflects the most recent notification the holder filed, so the dates differ and the smaller stakes may have changed since.

Everyone else, including other index funds, pension funds, activist investor Cevian Capital, and Swiss and Swedish retail shareholders, sits below 3% and is not individually disclosed.

A traditional funding-round table does not fit a company this old, so the table below tracks the capital events that shaped today's register.

Investor AB is the anchor owner. It is the listed holding company of Sweden's Wallenberg family, and ABB is its single largest asset, accounting for about 23% of Investor's total assets. At the September 24, 2026 share price, its 265 million ABB shares were worth roughly CHF 21 billion. Investor holds the same 14.6% of capital and votes, because ABB has one share class. It has two representatives on ABB's board, and the Wallenberg sphere's ties to the company go back to ASEA in the early 20th century. Investor's second-quarter 2026 presentation showed ABB as the top performer in its listed portfolio, with a return of roughly 40%.

UBS Fund Management (Switzerland) crossed the 5% threshold in September 2024. As a fund manager, UBS holds the shares on behalf of its fund investors, so the stake reflects ABB's weight in Swiss equity portfolios rather than a strategic bet.

BlackRock last reported 4.17% in June 2023. Like UBS, it owns ABB largely through index products and ETFs. Because BlackRock only has to notify ABB when it crosses a threshold, its current stake may differ from that figure.

Cevian Capital, the Swedish activist fund, disclosed a stake of more than 3% in 2015 and became one of ABB's most vocal shareholders. Its managing partner Lars Förberg sat on ABB's board from 2017 until the March 2025 annual meeting. Cevian said in January 2025 that it would remain invested, and Reuters reported its stake was below 3%.

ABB has a single class of registered shares, so every share carries one vote. There are no founder shares, golden shares, or dual-class arrangements. Investor AB's influence comes from the size of its stake and its board seats, not from special voting rights.

The biggest pending change is the sale of ABB Robotics to SoftBank Group. ABB had planned to spin Robotics off as its own listed company, but in October 2025 it agreed instead to sell the division for an enterprise value of $5.375 billion. Robotics had about 7,000 employees and 2024 revenue of $2.3 billion, roughly 7% of the group. The sale fits SoftBank's broader push into robotics and physical AI, a push that dates back to its 2017 purchase of Boston Dynamics, a history covered in how Boston Dynamics is owned.

As of September 24, 2026, the deal had not been reported as closed. In its July 2026 results, ABB said it expected to complete the sale in the second half of 2026 and receive about $4.8 billion in net cash, below the roughly $5.3 billion it first estimated. Reuters still described the deal as agreed, not completed, on September 24, 2026. The sale changes what ABB owns, not who owns ABB: shareholders will hold a smaller, more electrification-focused company with more cash.

Morten Wierod is chief executive. A Norwegian electrical engineer, he joined ABB in 1998 and ran both the Motion and Electrification business areas before succeeding Björn Rosengren on August 1, 2024. He sits on the executive committee alongside CFO Christian Nilsson, who replaced long-serving CFO Timo Ihamuotila on February 1, 2026.

The rest of the executive committee includes the heads of the three business areas: Giampiero Frisio (Electrification), Brandon Spencer (Motion), and Peter Terwiesch (Automation). It also includes Carolina Granat (human resources), Karin Lepasoon (communications and sustainability), and Mathias Gaertner (general counsel).

Peter Voser, CEO of Royal Dutch Shell from 2009 to 2013, has chaired ABB since 2015 and also chairs its governance and nomination committee. He served as interim CEO from April 2019 to February 2020, and shareholders reconfirmed him as chairman at the March 2026 annual meeting.

The board has ten members: Voser, David Constable, Frederico Fleury Curado, Johan Forssell, Denise C. Johnson, Jennifer Xin-Zhe Li, Geraldine Matchett, David Meline, Claudia Nemat, and Mats Rahmström. Two of them represent Investor AB. Johan Forssell ran Investor AB as CEO from 2015 to May 2024 and now advises it on industrial holdings. Mats Rahmström is the former CEO of Atlas Copco, another Investor company. Both joined in March 2024, when Jacob Wallenberg, who had been on ABB's board since 1999 and vice chairman since 2015, stepped down along with Gunnar Brock. Geraldine Matchett chairs the finance, audit, and compliance committee, and Frederico Fleury Curado chairs the compensation committee.

ABB's purchase of U.S. boiler maker Combustion Engineering, agreed in 1989, brought thousands of asbestos injury claims with it. Higher provisions for those claims, along with other charges, pushed ABB to a $691 million net loss for 2001 and contributed to a financial crisis in 2002. The claims were resolved through a final settlement in 2006. The episode is a reminder that acquisitions can carry liabilities for decades, the kind of exposure a risk register template is built to surface before a deal closes.

In December 2022, ABB resolved U.S. investigations into bribes paid to an official at Eskom, South Africa's state power utility, in connection with contracts at the Kusile power station between 2014 and 2017. The resolution included a $315 million criminal penalty under a deferred prosecution agreement with the U.S. Department of Justice and a $75 million civil penalty with the Securities and Exchange Commission, which put the total at $460 million. The DOJ credited payments to authorities in South Africa, Switzerland, and Germany against its penalty, and ABB said the settlements cost it $327 million in total. ABB had already agreed in December 2020 to repay about $104 million to Eskom. The case put ABB's compliance systems under scrutiny, and the audit committee's compliance role remains a focus for shareholders.

The SoftBank transaction needs clearance from regulators including those in the European Union, China, and the United States. Industrial robots sit close to national security and supply chain debates, and China is a major robotics market. Until the deal closes, there is a risk of delay or conditions, and ABB has already lowered its expected net cash proceeds from about $5.3 billion to about $4.8 billion.

ABB delisted its ADRs from the NYSE in May 2023 and later filed to deregister and suspend SEC reporting. At the time, about 130 million ADRs, around 6.6% of issued shares, were outstanding. U.S. investors can still buy ABB over the counter, but they no longer get SEC filings, and the company now reports mainly under Swiss rules.

ABB's ownership combines a stable anchor with a broad free float. Investor AB's 14.6% is not a controlling stake, but it is almost three times the size of the next holder, and it comes with two board seats. That gives management a patient owner that has stayed invested through a merger, an asbestos crisis, and several restructurings. It also means major strategic moves, such as selling Robotics rather than spinning it off, are unlikely to happen without the support of the Wallenberg sphere.

For other shareholders, the single share class is a real protection. Investor AB has influence, but it has no extra votes. Every shareholder is on the same terms, which is not always the case among large family-linked European groups.

The Robotics sale shows how the ownership model shapes strategy. Rather than keep a lower-margin, cyclical business, ABB is selling it to an owner with a different thesis. SoftBank wants robots for its physical AI bet; SoftBank's ownership structure, dominated by founder Masayoshi Son, lets it make long-dated wagers that ABB's shareholders did not want to fund. ABB is returning cash through buybacks and a rising dividend, which rose to CHF 0.94 per share for 2025. Investors can measure that payout with a dividend yield calculator.

For customers, the result is an ABB more tightly focused on electrification and automation. Data centers are leading demand growth in Electrification, and its work on 800-volt direct current power ties it to the same AI build-out that powers Nvidia's data center business. A stable ownership base gives ABB room to invest in that shift without the pressure of a takeover or a single controlling shareholder.

ABB is a public company owned by its shareholders. The largest is Investor AB, the Wallenberg family's holding company, with 14.6% of voting rights as of June 30, 2026. UBS Fund Management and BlackRock are the only other disclosed holders above 3%.

Morten Wierod has been CEO since August 1, 2024. He succeeded Björn Rosengren and previously led ABB's Electrification and Motion business areas.

Yes. ABB trades on the SIX Swiss Exchange under ABBN and on Nasdaq Stockholm under ABB. It delisted its ADRs from the New York Stock Exchange in May 2023, and they now trade over the counter in the U.S.

ABB was created in 1988 by merging two older companies. ASEA was founded by Ludvig Fredholm in Sweden in 1883, and Brown, Boveri & Cie was founded by Charles Brown and Walter Boveri in Switzerland in 1891.

ABB agreed in October 2025 to sell ABB Robotics to SoftBank Group for an enterprise value of $5.375 billion. As of September 24, 2026, the sale was still pending regulatory approvals, with ABB expecting to close in the second half of 2026.

ABB's market capitalization was about CHF 146 billion on September 24, 2026, with the share price up roughly 40% from a year earlier. At the end of 2022, it was about CHF 52 billion.
