UBS must face US investor litigation over Credit Suisse demise

A U.S. judge has ruled that UBS must face two lawsuits from American investors alleging that the former Credit Suisse defrauded them with false and misleading statements about its financial condition prior to its March 2023 demise. Judge Colleen McMahon allowed Core Capital Partners to sue on behalf of Credit Suisse Additional Tier 1 (AT1) bondholders, whose bonds were controversially written down to zero, and also permitted a class action for purchasers of the bank's American depositary shares and other bond issues. This decision is significant as it allows major litigation to proceed against UBS, potentially impacting its inherited liabilities from the Credit Suisse acquisition, despite defendants arguing the Swiss regulator's writedown, not fraud, caused the losses.

Analysis

A recent U.S. court ruling has permitted two significant lawsuits against UBS to proceed, stemming from alleged fraud by Credit Suisse prior to its March 2023 acquisition. U.S. District Judge Colleen McMahon determined that investors can sue UBS over purportedly false and misleading statements regarding Credit Suisse's financial health. One lawsuit, led by Core Capital Partners, represents U.S. holders of Additional Tier 1 (AT1) bonds, which were controversially written down to zero by the Swiss regulator FINMA. The second is a class action for holders of Credit Suisse's American depositary shares and other bonds. Critically, the judge found it "plausible" that the defendants' alleged fraud, not solely the regulatory write-down, directly contributed to the AT1 bonds' value declining to zero. This development exposes UBS to substantial inherited legal liabilities and prolongs the uncertainty surrounding the total cost of the Credit Suisse integration, representing a material legal and financial overhang for the bank.

Key Decisions for Investors

• Investors should recognize that this court decision materializes a significant legal overhang for UBS, creating a long-tail risk of potentially substantial, unquantified financial damages or settlements from inherited Credit Suisse liabilities.
• It is prudent to closely monitor the progress of these U.S. lawsuits, as any developments will be a key catalyst for UBS's stock and will influence sentiment regarding the ultimate cost and success of the Credit Suisse integration.
• The ongoing legal uncertainty justifies a higher risk premium for UBS shares, as the potential financial impact of these cases could suppress valuation multiples until there is greater clarity on the outcome.
