Here are 1-3 brief analogies to describe Dynex Capital (DX):

• Goldman Sachs, but focused on mortgage-backed securities. (This highlights its role as a sophisticated financial investor and trader in a specific debt market.)
• An apartment REIT (like Equity Residential), but for mortgage loans instead of physical buildings. (This explains its Real Estate Investment Trust (REIT) structure, but clarifies that it profits from mortgage debt rather than owning physical property.)

• Mortgage-Backed Securities (MBS) Investments: Acquisition and management of a diversified portfolio primarily consisting of agency residential and commercial mortgage-backed securities.
• Financing and Leverage: Utilizing repurchase agreements to finance their portfolio investments and enhance returns.
• Interest Rate Risk Management: Employing interest rate hedges, such as swaps and swaptions, to mitigate the impact of interest rate volatility on their portfolio.

Dynex Capital (DX) - Major Customers

Dynex Capital (symbol: DX) is a mortgage Real Estate Investment Trust (mREIT). Unlike a traditional company that sells physical products or services to customers, Dynex Capital operates primarily as an investor in financial assets, specifically agency residential mortgage-backed securities (MBS).

Therefore, Dynex Capital does not have "customers" in the conventional sense who purchase goods or services directly from them. Instead, its business involves engaging in financial transactions with a variety of other financial institutions as counterparties in the capital markets.

While Dynex Capital does not "sell" a product or service to other companies in the traditional sense, its primary business interactions are conducted with these other financial institutions. These interactions include:

• Sellers of Mortgage-Backed Securities (MBS): Dynex Capital purchases MBS from various broker-dealers and investment banks in the secondary market. These institutions facilitate the buying and selling of securities.
• Repurchase Agreement (Repo) Counterparties: To finance its investments, Dynex Capital enters into repurchase agreements with large commercial banks and investment banks. These institutions provide financing against Dynex Capital's MBS holdings.
• Derivative Counterparties: For hedging interest rate risk, Dynex Capital utilizes derivative instruments (such as interest rate swaps) with various financial institutions.

Due to the transactional nature of financial markets and the wide array of financial institutions Dynex Capital transacts with, the company does not typically have identifiable "major customers" or disclose specific names of these counterparties as "customers." The relationships are dynamic and spread across numerous market participants rather than concentrated with a few key buyers of a product or service.

In summary, Dynex Capital's business is centered on financial market activities where its counterparties are primarily other financial institutions (e.g., investment banks, commercial banks, broker-dealers), rather than selling products or services to a defined customer base.

Dynex Capital (symbol: DX) is expected to drive future revenue growth over the next 2-3 years through several key strategies and market dynamics:

1. Strategic Capital Raising and Deployment: Dynex Capital has consistently demonstrated its ability to raise new equity capital, which is then strategically deployed into its investment portfolio. For instance, in the third quarter of 2025, the company raised $254 million in new common equity capital, contributing to a year-to-date total of $776 million. In 2024, they raised $332.0 million. This expanded capital base allows for further investment in income-generating assets.
2. Growth and Active Management of Investment Portfolio: The company actively grows and manages its portfolio, primarily consisting of Agency Residential Mortgage-Backed Securities (RMBS) and Agency Commercial Mortgage-Backed Securities (CMBS). The portfolio expanded by 10% in Q3 2025 compared to the prior quarter, and over 50% since the beginning of the year. In the third quarter of 2025 alone, Dynex purchased $2.4 billion in Agency RMBS and $464 million in Agency CMBS, adding higher-yielding assets that contribute to increased net interest income.
3. Favorable Interest Rate Environment and Net Interest Margin Expansion: Dynex Capital anticipates benefits from potential Federal Open Market Committee (FOMC) rate cuts, which are expected to positively impact its net interest margin in the upcoming quarters. A decline in interest rates can lead to asset appreciation and tightening of mortgage spreads, enhancing the profitability of its leveraged portfolio.
4. Opportunistic Positioning in Agency RMBS and CMBS: The company focuses on opportunistic positioning and disciplined risk management to capitalize on attractive returns offered by Agency RMBS spreads and seize opportunities in Agency CMBS. This involves actively managing the portfolio to adapt to market conditions and generate strong returns from these high-quality, liquid fixed-income products.
5. Expansion of Operational Capabilities: The opening of a new office in New York City is a strategic move designed to enhance trading and portfolio management capabilities. This expansion aims to attract top talent and strengthen relationships with business partners, which is expected to lead to more efficient investment strategies and ultimately contribute to revenue growth.
