ABB launches new share buyback

program of up to $1 billion

On April 1, 2024, ABB will launch

its previously announced new

share buyback program of up to $1

billion.

Based on the current ABB share price

this represents a maximum of

approximately 21.3 million

shares. The

maximum number of shares

that may be repurchased under

this new program on any given

trading day

is 692,486.

This new program is consistent with

ABB’s capital allocation principles

targeting to maintain a strong

investment grade rating. Since July

2020, ABB has repurchased

about 308 million shares for capital

reduction purposes for a total amount

of approximately $9.4 billion.

The total number of ABB’s issued shares

is 1,882,002,575. This includes

21,387,687 shares that were

repurchased under the 2023–2024

share buyback program and are expected

to be cancelled in Q2 2024.

ABB will use the capital band

approved at its Annual General

Meeting 2023 for cancellation

of these shares.

ABB currently owns approximately

30 million treasury shares.

The new share buyback program is

for capital reduction purposes

and will be executed on a second

trading

line on the SIX Swiss Exchange

(Valor: 35.767.961; ISIN: CH035 767 961 9). It is planned

to run from

April 2, 2024, until January 31, 2025,

following a decision to adjust

the timing of its share buyback

cycle to

align with the announcement

of its Q4 2024 results and 2024 dividend

proposal.

The new share buyback program will

be managed by a bank mandated

by ABB that, based on trading

parameters received from ABB, will

make its trading decisions

concerning the timing of share

repurchases

independently of ABB. ABB can

change these parameters outside

of its closed periods and if it is not

possession of any inside information.

The purchase price per share will

not exceed the higher of

the price of the last independent

trade on the

ordinary trading line on the SIX

Swiss Exchange and the highest

current independent bid price

on the

ordinary trading line on the SIX

Swiss Exchange. In addition,

customary spreads on purchases

on the

second trading line on the SIX Swiss

Exchange will be paid,

observing the limitations of the Ordinance

Financial Market Infrastructures and

Market Conduct in Securities

and Derivatives Trading (FMIO). Payment

for the shares will be made in cash.

The buyback program is being

carried out in accordance with the

Ordinance on Financial Market

Infrastructures and Market Conduct in

Securities and Derivatives

Trading (FMIO), the Market Abuse

Regulation (EU) No 596/2014

and the Commission Delegated

Regulation (EU) No 2016/1052.

Weekly

updates on the program will be published

on ABB’s investor relations website at

https://global.abb/group/en/investors/investor-and-shareholder-resources/share-buybacks

and issued by

press release.

ABB announced today that Tarak Mehta, President Motion

Business Area and Member of the

Executive

Committee, has decided to leave

ABB since he has accepted

the role as CEO of another company. Tarak

Tarak joined ABB in 1998 and has since then held a number of positions

Area President, Tarak has contributed to achieving

a record high

operational EBITA margin in the past year in our Motion

business and the Business Area is

well-positioned

to contribute to ABB’s higher financial

targets going forward. Before

that, he played a key role in

further

strengthening our leading

position in the United States, ABB’s largest

market, for our Electrification

business,” said CEO Björn Rosengren.

“We thank Tarak for his outstanding contribution to the success

our company and wish him all the best

for both his professional

and personal future endeavors.”

“I would like to express my sincere

gratitude and appreciation

to everyone I have worked with over

the years.

Thank you for your support, efforts, guidance

and the results we have achieved

together. It has been a

wonderful journey of 26 years filled
