UBS must face US investor litigation over Credit Suisse demise

A U.S. judge has ruled that UBS, as the successor to Credit Suisse, must face two investor lawsuits alleging Credit Suisse defrauded them with false statements prior to its March 2023 collapse. The decision allows U.S. purchasers of Credit Suisse's Additional Tier 1 (AT1) bonds and American depositary shares (ADS) to pursue claims, rejecting defendants' arguments that the unprecedented $20 billion AT1 bond writedown by Swiss regulators was the sole cause of losses. This ruling underscores the ongoing legal liabilities for UBS stemming from the Credit Suisse acquisition and the contentious nature of the AT1 bond treatment.

Analysis

A U.S. District Court ruling has advanced two significant lawsuits against UBS, compelling the bank to confront legacy liabilities from its acquisition of Credit Suisse. The decision permits U.S. investors in Credit Suisse's Additional Tier 1 (AT1) bonds and American depositary shares to proceed with claims alleging they were defrauded by false statements about the bank's financial health prior to its March 2023 collapse. Critically, the judge found it plausible that these alleged misstatements contributed to the decline and eventual $20 billion writedown of the AT1 bonds, rejecting the defense's argument that the Swiss regulator's (FINMA) action was the sole cause of the loss. This legal development perpetuates a material overhang for UBS, underscoring that the integration of Credit Suisse involves absorbing substantial and ongoing litigation risks. The lawsuits also target former senior executives, including the CEO and CFO, highlighting a focus on management accountability that could lead to further damaging revelations.

Key Decisions for Investors

• Investors should price a persistent legal risk premium into UBS's valuation, as these lawsuits represent a prolonged period of uncertainty and the potential for significant financial damages or settlements.
• Closely monitor UBS's financial disclosures for any changes to litigation reserves, as this will be a key quantitative indicator of the perceived financial impact of these and other legacy Credit Suisse cases.
• Consider the precedent-setting implications for the broader AT1 bond market, as the case challenges the finality of regulatory writedowns in instances of alleged fraud, potentially recalibrating the risk profile of such instruments.
