The scrutiny centers on a January 29, 2026, regulatory filing that revealed a sharp contraction in PennyMac's servicing segment. Pretax income plummeted to $37.3 million, a significant drop from the $157.4 million reported in the previous quarter. The company attributed the decline to heightened prepayment activity fueled by lower mortgage rates, which accelerated the realization of mortgage servicing rights cash flows.

Investors reacted sharply to the disclosures, driving PennyMac shares down $49.78 to close at $99.92 on January 30, 2026. The Rosen Law Firm is now seeking shareholders who incurred losses during this period to participate in a prospective class action. Those interested in joining the litigation are directed to contact Phillip Kim at 866-767-3653 or submit their details via the firm’s online portal.
