Swiss investment bank UBS Group AG is preparing to lay off as many as 36,000 people in the wake of its planned takeover of rival Credit Suisse โ significantly more than first planned.
Citing insiders at the bank, the Swiss newspaper SonntagsZeitung reported Sunday that UBS UBS, -3.00% plans to cut 20% to 30% of its workforce. That would be between 25,000 and 36,000 of UBSโs 120,000 full-time positions following the combination of the two banks. The newspaper said up to 11,000 layoffs would be in Switzerland.
A spokesman for UBS declined to comment on the report.
UBS shares UBSG, -2.88% fell 3.3% in Zurich, and Credit Suisse CSGN, -2.36% CS, -1.58% stock dropped 2.7%.
UBS agreed to buy Credit Suisse in March for roughly $3.25 billion, after a wave of withdrawals threatened Credit Suisseโs stability following the failures of Silicon Valley Bank and Signature Bank in the U.S.
Separately, the Swiss Attorney Generalโs Office has opened an investigation into Credit Suisseโs takeover by UBS.
It didnโt specifically identify any issue it will be investigating.
The body added that it wants to โobtain an overall overview of the numerous aspects of the events relating to Credit Suisse,โ notably those mentioned in the media, and โidentify any criminal offensesโ that could fall within the jurisdiction of the Swiss public prosecutor.
Some U.S. investors have launched legal action against Credit Suisse, claiming the bank, which has been embroiled in scandals in recent years, misled them over its prospects ahead of the share collapse. The Swiss regulatorsโ decision to write down Credit Suisseโs Additional Tier 1 (AT1 or contingent convertibleย CoCo bonds) as part of UBSโs planned takeover, has also infuriated bondholders.
UBS will hold its annual general meeting on Wednesday.
