Howard Amster filed a 13D disclosure showing a 9.0% stake in Redwood Trust, the Marin County mortgage REIT trading at $6.82 and carrying a $940 million market capitalization. The position makes Amster the third-largest disclosed holder in a company that has underperformed the Mortgage REIT Index by 18 percentage points over the past twelve months.
Redwood Trust operates two franchises: a residential mortgage conduit that securitizes jumbo loans outside Fannie Mae channels, and a business-purpose lending arm financing single-family rentals and bridge loans. The company reported $31 million in net income for Q3 2024, down from $48 million in the prior year quarter, with net interest margin compressing 22 basis points to 1.89% as higher funding costs outpaced asset yield pickup. Book value per share stands at $8.14, implying Amster entered at a 16% discount to stated equity. Management has bought back $28 million in stock over the past six quarters but paused repurchases in Q3 as liquidity tightened.
Amster has taken two prior mREIT positions since early 2023, both resolved within nine months. At Arbor Realty Trust, he pushed for asset sales and capital redeployment before exiting in Q4 2023 following management's announcement of a portfolio review. At Ready Capital, a 7.4% stake filed in March 2024 preceded the company's decision to sell its Small Business Administration lending unit for $263 million in September; Amster reduced his holding to 4.1% by October. The pattern: file, pressure management on capital efficiency, exit once a liquidity event or strategic shift is announced.
Redwood's challenges invite similar scrutiny. The company holds $443 million in cash and unencumbered assets against $2.8 billion in recourse debt, a coverage ratio that has contracted from 1.9x in 2022 to 1.4x today. Its residential platform originated $2.1 billion in jumbo loans during Q3, but gain-on-sale margins fell to 78 basis points from 114 basis points a year earlier as securitization spreads widened. The business-purpose lending segment, which contributed 41% of earnings in 2023, saw originations drop 29% year-over-year as higher rates curtailed bridge loan demand. Activists typically focus on whether management should retain both franchises or monetize one to stabilize the other.
Operators should monitor three catalysts over the next ninety to one-hundred-twenty days. First, whether Amster requests board representation or files a public letter outlining capital allocation demands; 13D filers in sub-$1 billion mREITs historically move to board engagement within sixty days if stock price remains flat. Second, Redwood's Q4 earnings call in February, where management will address 2025 origination guidance and any strategic review following Amster's entry. Third, securitization market conditions in January and February; if residential mortgage-backed security spreads tighten 15-20 basis points from current levels, Redwood's gain-on-sale margins improve materially, reducing pressure for asset sales. If spreads widen further, Amster's case for portfolio pruning strengthens.
Redwood's next board meeting occurs in March 2025, and proxy filing season opens in April for the company's June annual meeting.
