Ad hoc Announcement pursuant to Art. 53 Listing Rules of SIX Swiss Exchange

The ABB Board of Directors has appointed Morten Wierod as Chief Executive Officer. He will take office

on August 1, 2024, and succeed Björn Rosengren, who will step down from his position

as Chief Executive

Officer effective July 31, 2024, and retire as of December 31, 2024.

From August 1, 2024, until the end of the year, Björn Rosengren will advise and assist Morten Wierod and

the Executive Committee to ensure a seamless transition.

Morten Wierod (52), a Norwegian citizen, has been appointed by the Board following a thorough

selection

process. He joined ABB in 1998 and has been serving as a member of

ABB's Executive Committee since

2019, currently as President of the Electrification Business Area and previously

able to

name an outstanding internal candidate to lead ABB. Morten is a strong

successor to Björn with his deep

understanding of ABB and our decentralized operating model in addition

to his extensive expertise across

our key customer segments and strong performance track record. Under

Morten’s leadership, ABB will

continue to focus on our key priorities while our new financial

and sustainability targets remain firmly in

place.

“At the same time, the Board is extremely grateful to Björn for his outstanding

leadership over the past four

years. He was instrumental in aligning ABB’s business portfolio to our purpose and significantly improving

our financial and sustainability performance thanks to our ABB Way operating model. Björn will hand over

an efficient, more profitable and faster growing ABB.”

Morten Wierod commented: “I am grateful that the Board has given me the opportunity to

lead this great

company with its people and technologies that are at the heart

of building a low-carbon ociety. It has been a

privilege to work alongside Björn over the past years. After

we have set more ambitious financial and

sustainability standards not long ago, I will continue building on our decentralized

operating model to

capture the full potential of our market leading positions in electrification and automation.”

Björn Rosengren commented: “It has been an honor to lead ABB over the past

years and I am convinced that

the company will be in good hands with Morten. Together with our more than 105,000 people, we have

transformed ABB into an agile and purpose-driven leader in electrification

and automation that has an

ZURICH, SWITZERLAND, FEBRUARY 23, 2024

ABB publishes 2023 Integrated Report

Ad hoc Announcement pursuant to Art. 53 Listing Rules of SIX Swiss Exchange

●

Report covers ABB’s 2023 strategy, business, governance, financial and sustainability performance

●

76 percent reduction of scope 1 and 2 GHG emissions since 2019

●

74 megatons CO2e emissions avoided throughout lifetime of products sold in

2023

ABB today published its Integrated Report, which is the company’s primary report at Group level. The

report

integrates the most important material information about the company’s strategy, business, governance as

well as its financial and sustainability performance. In addition to

the Integrated Report, ABB’s 2023 Annual

Reporting Suite published today includes its Financial Report,

Corporate Governance Report, Compensation

Report, Sustainability Report as well as the Form 20-F that was filed with

the United States Securities and

Exchange Commission.

ABB Chairman Peter Voser

said: “By combining our technology leadership in electrification and

automation

with our decentralized ABB Way operating model we create holistic value for our stakeholders while

enabling a more sustainable and resource-efficient future. In 2023, we took advantage

of the positive market

environment and strong secular demand drivers and our financial and sustainability

achievements show that

we are heading in the right direction.”

ABB’s value creation model provides a comprehensive summary of the holistic value the company generates

for all stakeholders across its entire value chain, including customers,

employees, investors and suppliers. It

outlines the inputs that ABB needs to create value and illustrates how

the Group transforms these inputs into

outputs and outcomes through its decentralized operating model.

Commenting on ABB’s achievements in 2023, CEO Björn Rosengren said: “2023 was a record year for

ABB. We delivered strong performance and as a technology leader in electrification and automation, ABB

continued to play a key role in accelerating the energy transition for a net-zero

future. Our solutions helped

to optimize, electrify and decarbonize industry, buildings, power and transport – sectors that together account

for the lion’s share of global energy-related carbon emissions. By doing this, we made the ways we move,

produce, work and live more sustainable and we continued to make good

progress

1/3

towards achieving our sustainability targets. I am proud of the ABB team for delivering such

good results

and creating value for all our stakeholders.”

Good progress towards sustainability goals

As part of ABB’s efforts to enable a low-carbon society,

the company submitted updated CO

e emissions

reduction targets aligned with the Net-Zero Standard of the Science-Based Targets initiative (SBTi) for

validation. These targets include ABB’s scope 1 and 2 emissions, which it aims to reduce by 80 percent by

2030 and 100 percent by 2050, compared to a 2019 baseline, as well as

its scope 3 emissions, covering the

rest of its value chain, which it aims to cut by 25 percent by 2030 and 90 percent

by 2050, compared to a

2022 baseline.

In 2023, ABB achieved a reduction of 76 percent in its scope 1 and 2 emissions

compared to 2019 and

scope 3 emissions stayed flat compared to 2022, based on measured energy loss (representative

scenario).

When calculating based on energy input (strict scenario) the company reports an 11 percent increase

in scope

3 emissions compared to 2022.

The company also reduced its energy consumption by 21 percent compared to 2019.

At the end of 2023,

64 percent of ABB’s energy consumption and 94 percent of its electricity came from renewable sources.

In 2023, the products ABB sold to customers will avoid 74 megatons of

emissions over their lifetime. This

contributes to the company’s ambition to support customers in avoiding 600 megatons of GHG emissions

from 2022 to 2030, based on all the products the company expects to sell

over that period.

As part of the preserving resources pillar of its Sustainability Agenda, ABB

further reduced the amount of

waste it sends to landfill to 6.3 percent in 2023, a 40 percent reduction since 2019, while

recycling 86 percent

of its waste. By the end of 2023, ABB had also assessed 31 percent of its product portfolio

as part of its goal

of covering at least 80 percent of its portfolio of products and solutions with

its Circularity Approach by

2030.

Finally, in line with its goal of promoting social progress, in 2023, ABB reduced its rate of lost time caused

by injuries (LTIFR) by 9 percent to industry-leading levels. And it increased the number of women in senior

management positions to 21 percent, up from 17.8 percent in 2022. The company

also expanded its programs

for community engagement to cover education, emergency and disaster relief, community

empowerment,

and environment and conservation, and supported more than 500 community

projects and charities in 2023.
