Rosen Law Firm said it was investigating potential securities claims on behalf of shareholders of PennyMac Financial Services, Inc. and Barclays PLC over allegations that the companies issued materially misleading business information. In the PennyMac matter, the firm cited the company’s January 29, 2026, disclosure that fourth-quarter 2025 servicing-segment pretax income fell to $37.3 million from $157.4 million in the prior quarter and $87.3 million a year earlier. PennyMac also reported pretax income excluding valuation-related items of $47.8 million, down 70% quarter over quarter, primarily because lower mortgage rates increased prepayment activity and realization of mortgage servicing rights. PennyMac shares fell $49.78, or 33.3%, to $99.92 on January 30, 2026. In the separate Barclays matter, the firm cited a February 27, 2026, Reuters report on the collapse of UK mortgage provider Market Financial Solutions Ltd., or MFS, and a reported £600 million ($809.70 million) Barclays exposure. Barclays ADS fell 3.99% on February 27 and 2.3% on March 2, 2026. Rosen said both prospective actions seek recovery of investor losses and may be pursued without upfront fees or costs under contingency-fee arrangements; past results do not guarantee a similar outcome.
