Atos issued a statement confirming a Reuters report that is seeking to buy DXC in what it said was a "friendly transaction" to create a digital services powerhouse with a global presence.

The French firm, led by chief executive Elie Girard, made a formal approach to DXC this week valuing the New-York listed company at more than $10 billion including debt, two sources told Reuters on condition of anonymity.

DXC said in a statement it had received a takeover proposal on Wednesday night and had no prior knowledge of any interest from Atos. It called the offer "unsolicited, preliminary and non-binding", adding its board of directors would evaluate it.

Shares in DXC, which is a former Hewlett Packard Enterprise business, were up 10% to $29.13 at 1517 GMT, while Atos dropped 12% on the news, making it the worst performing stock on the Paris SBF-120 index.

Atos is working with advisers on the potential DXC bid, which would boost its U.S. presence, giving it access to a wide range of clients and B2B products including analytics and cloud applications as well as IT outsourcing services.

Atos said in its statement it would apply "financial discipline" in pursuing DXC, cautioning that there was no certainty that the approach would result in a deal.

If successful, a combination with DXC would lead to synergies and cost savings for Atos, which has been on an acquisition spree in recent years, the sources said.

The French firm spent $3.4 billion to buy Michigan-based IT services provider Syntel in a cash deal in 2018, ranking as its biggest deal so far.

It is now looking to take advantage of investor appetite for pandemic resilient assets in technology to clinch a deal that would be in the region of its own market value of 8.2 billion euros ($10.1 billion), the sources said.

RISING DEBT

DXC, founded in 2017 when Hewlett Packard Enterprise spun off its enterprise services business, has been grappling with rising debt, with boss Mike Salvino taking the helm in 2019 and subsequently announcing a strategic review of non-core assets.

"DXC is too small to operate on its own in a low margin world," one of the sources said.

DXC unveiled plans on Wednesday to sell its Fixnetix unit - which provides outsourced front-office trading services to investment banks, hedge funds and exchanges - to Options Technology for an undisclosed amount.

Last year it pocketed $5 billion from the sale of its healthcare technology business to private equity firm Veritas Capital.

The Tysons, Virginia-based firm, which has a market value of $6.7 billion, saw its revenues fall to $19.6 billion in 2020 from $20.75 billion in 2019 while its total debt rose to $9.9 billion in 2020 from $7.4 billion in 2019.

Atos has recently embarked on a series of bolt-on acquisitions, buying cybersecurity, artificial intelligence and digital consultancy firms in a bid to grow its revenues by 5% to 7% in the mid-term.

It bought artificial intelligence and data science firm Miner & Kasch in April and U.S.-based cloud consulting group Maven Wave in 2020, as well as cybersecurity firm IDnomic and energy specialist X-Perion in 2019.

After cancelling its 2020 dividend payout in April, Atos said it would maintain its dividend policy and use remaining free cash flow to finance further acquisitions.
