The legal action, led by the firm Hagens Berman, targets the period between March 9 and August 5, 2026. According to the complaint, UWM entered into complex hedging transactions to protect against interest rate volatility during its planned $1.3 billion takeover of Two Harbors. When that deal collapsed in March 2026—following Two Harbors' decision to merge with CrossCountry Mortgage instead—UWM allegedly maintained these speculative hedges rather than unwinding them.

Investors remained largely unaware of the extent of this exposure until August 6, when UWM management admitted to a $603 million hedging loss and a $451 million net loss. The disclosure revealed a 38% plunge in total equity and prompted a recapitalization plan designed to dilute existing shareholders. By the time the market closed that day, UWM stock had fallen roughly 75% from the initial acquisition announcement in December 2025. Reed Kathrein, a partner at Hagens Berman, is now investigating why the company remained silent regarding these risks for months. Shareholders with significant losses have until October 13, 2026, to file for lead plaintiff status.
