Rosen Law Firm is investigating potential securities claims on behalf of Barclays PLC shareholders over allegations that the bank issued materially misleading business information. The investigation follows a Feb. 27 Reuters report about the collapse of UK mortgage provider Market Financial Solutions Ltd, or MFS, and a separate report that Barclays had a £600 million ($809.70 million) exposure to the lender. Barclays American Depositary Shares (ADS) fell 3.99% on Feb. 27 and 2.3% on March 2, 2026. The firm is preparing a class action seeking recovery of investor losses and says eligible investors may participate without upfront fees or costs under a contingency fee arrangement.
