Key Financial Metrics

Material Changes vs. Prior Period

• Net Loss vs. Net Income: The Company reported a net loss of $3.6 million in Q1 2026 compared to net income of $11.5 million in Q1 2025. This reversal was primarily driven by a $16.5 million net unrealized loss on investments, contrasting with an $0.8 million net unrealized gain in the prior year.
• Unrealized Losses: Significant unrealized losses were recorded on residential mortgage loans ($79.7 million) and commercial loans ($3.5 million), partially offset by a $68.2 million unrealized gain on securitized debt.
• Interest Income and Expense: Interest income increased to $129.8 million (from $109.1 million) due to a higher weighted average amortized cost of the portfolio. Interest expense rose to $109.2 million (from $90.3 million) due to higher financing balances and rates.
• Portfolio Composition: Total assets decreased by approximately $423 million year-over-year, reflecting principal repayments and a reduction in the residential mortgage loan portfolio.
• Dividends: The common stock dividend was increased to $0.24 per share (from $0.20 in Q1 2025).

Outlook, Risks, and Management Commentary

• Market Conditions: Management notes a "higher-for-longer" interest rate environment with the Federal Reserve pausing rate cuts due to persistent inflation and geopolitical tensions. The 30-year fixed mortgage rate rose to 6.4% by quarter-end.
• Legacy WMC Commercial Loans: Borrowers for the Legacy WMC Commercial Loans remain in maturity default. The Company extended the financing maturity for these loans to September 19, 2026, and is pursuing consensual sales of the underlying properties.
• Liquidity: As of March 31, 2026, the Company held $100.0 million in liquidity, comprising cash, committed financing on Home Equity Loans, and unencumbered Agency RMBS. The Company is in compliance with all financial covenants.
• Risks: Key risks include interest rate volatility affecting fair value, liquidity constraints from margin calls, credit risk from borrower defaults, and prepayment risk impacting yield. The Company utilizes interest rate swaps to hedge interest rate risk.
• Guidance: The filing does not provide specific forward-looking financial guidance for the full year 2026, though management expects to hold Legacy WMC Commercial Investments until maturity or opportunistically exit them.

Investor Verification Checklist

• Unrealized Loss Drivers: Verify the specific assumptions (prepayment rates, default probabilities, loss severities) used in the Level 3 fair value models that resulted in the $16.5 million net unrealized loss.
• Legacy WMC Resolution: Monitor the progress of the consensual sales or deed-in-lieu of foreclosure for the Legacy WMC Commercial Loans, which are currently in maturity default.
• Liquidity Cushion: Assess the adequacy of the $100 million liquidity buffer against potential margin calls if credit spreads widen or interest rates rise further.
• Dividend Sustainability: Evaluate the ability to maintain the increased $0.24 quarterly dividend given the GAAP net loss and reliance on Earnings Available for Distribution (EAD) of $0.26 per share.
• Financing Maturities: Review the concentration of financing arrangements maturing within the next 30 to 90 days to assess refinancing risk.
