The investigation centers on a January 29, 2026, regulatory filing where PennyMac disclosed a significant downturn in its servicing segment. Pretax income for the fourth quarter of 2025 plummeted to $37.3 million, a sharp decline from the $157.4 million reported in the previous quarter. The company attributed this contraction to increased mortgage servicing rights cash flows, spurred by higher prepayment activity as mortgage rates fell.

Market reaction to the disclosure was immediate and severe. On January 30, 2026, PennyMac shares fell $49.78, closing at $99.92. Rosen Law Firm is currently assessing whether these financial results were preceded by misleading statements that impacted investor decisions. Attorneys Phillip Kim and Laurence Rosen are leading the outreach, seeking to consolidate shareholders for a prospective class action suit. Participation in such actions typically operates on a contingency fee basis, meaning investors do not pay out-of-pocket costs to join the litigation.
