Dynex Capital, Inc. functions as a mortgage real estate investment trust (REIT), primarily engaging in leveraged investments within the U.S. mortgage-backed securities (MBS) market. Its investment portfolio includes a variety of MBS, such as agency and non-agency types, comprising residential mortgage-backed securities, commercial mortgage-backed securities (CMBS), and specialized CMBS interest-only instruments. Agency MBS distinguish themselves by a principal payment guarantee from a U.S. government body or a government-sponsored enterprise like Fannie Mae or Freddie Mac. Conversely, non-agency MBS lack this governmental assurance. For federal income tax purposes, the company qualifies as a REIT, which generally allows it to avoid federal corporate income taxes, provided it distributes at least 90% of its taxable earnings to its shareholders. Dynex Capital, Inc. was founded in 1987 and maintains its corporate headquarters in Glen Allen, Virginia.
