Re: Proposed Sale of Up to 99,326,438 Shares of Common Stock under Registration Statement on Form S-3 (File No. 333-289004)

Ladies and Gentlemen:

We have acted as counsel to Dynex Capital, Inc., a Virginia corporation (the “Company”), in connection with the offer and sale by the Company from time to time on or after the date hereof of up to 99,326,438 shares (the “Placement Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”) pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-289004), which became automatically effective upon filing with the U.S. Securities and Exchange Commission (the “Commission”) on July 28, 2025 (the “Registration Statement”), the related prospectus included therein (the “Base Prospectus”) and the prospectus supplement dated July 28, 2026 (together with the Base Prospectus, the “Prospectus”) filed with the Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”) and the terms of that certain Distribution Agreement, dated as of June 29, 2018, as amended on May 31, 2019, August 3, 2021, June 3, 2022, February 10, 2023, October 29, 2024, May 1, 2025, July 29, 2025, January 27, 2026, April 28, 2026, and July 28, 2026 by and among the Company, BTIG, LLC, Citizens JMP Securities, LLC, Goldman Sachs & Co. LLC, JonesTrading Institutional Services LLC, J.P. Morgan Securities LLC, Keefe, Bruyette & Woods, Inc., Morgan Stanley & Co. LLC, RBC Capital Markets, LLC, UBS Securities LLC and Wells Fargo Securities, LLC (the “Distribution Agreement”) and in the manner described in the Prospectus. The Placement Shares will be issued from time to time in public offerings at market or negotiated prices under Rule 415 of the Securities Act.

As counsel for the Company, we have examined originals or copies, certified or otherwise identified to our satisfaction, of: (i) the Registration Statement, including the Base Prospectus and the Prospectus; (ii) the Company’s Amended and Restated Articles of Incorporation, as amended through the date hereof (the “Charter”); (iii) the Company’s Amended and Restated Bylaws, as amended through the date hereof; (iv) certain resolutions of the Company’s Board of Directors or a duly constituted and acting committee thereof relating to the issuance, sale and registration of the Placement Shares; and (v) the Distribution Agreement. In addition, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other

instruments as we have deemed relevant and necessary for the purposes of rendering the opinions set forth herein.

In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. In making our examination of documents executed by parties other than the Company, we have assumed that each other party has the power and authority to execute and deliver, and to perform and observe the provisions of, such documents and has duly authorized, executed and delivered such documents, and that such documents constitute the legal, valid and binding obligations of each such party. We also have assumed the integrity and completeness of the minute books of the Company presented to us for examination. With respect to certain factual matters, we have relied upon certificates or comparable documents of public officials and of officers or representatives of the Company. We have also assumed that (i) upon the issuance of any Placement Shares, the total number of shares of Common Stock issued and outstanding will not exceed the total number of shares of Common Stock that the Company is then authorized to issue under the Charter, and (ii) the Placement Shares will not be issued in violation of the ownership limit contained in the Charter.

Based upon, subject to and limited by the foregoing, and such other examination of law and fact as we have deemed necessary, we are of the opinion that the Placement Shares have been duly and validly authorized and upon issuance, delivery and payment therefor in the manner contemplated by the Registration Statement, the Prospectus and the Distribution Agreement, will be validly issued, fully paid and nonassessable.

This opinion letter is based as to matters of law solely on the applicable provisions of the internal laws of the State of New York and the Virginia Stock Corporation Act, as currently in effect. We express no opinion herein as to any other laws, statutes, ordinances, rules or regulations.

This opinion is furnished to you in connection with the filing by the Company of a Current Report on Form 8-K relating to the offer and sale of the Placement Shares, which Current Report on Form 8-K will be incorporated by reference into the Registration Statement and the Prospectus and may not be relied upon for any other purpose without our express written consent. No opinion may be implied or inferred beyond the opinion expressly stated. This opinion is given as of the date hereof, and we assume no obligation to advise you of any changes in applicable law or any facts or circumstances that come to our attention after the date hereof that may affect the opinion contained herein.

We hereby consent to the filing of this opinion as an exhibit to the above-described Current Report on Form 8-K and to the reference to our firm contained under the heading “Legal Matters” in the Base Prospectus and the Prospectus. In giving this consent, we do not admit that we are in the category of persons whose consent is required by Section 7 of the Securities Act or the rules and regulations promulgated by the Commission.

Re:    Dynex Capital, Inc. —

Status as a Real Estate Investment Trust

Ladies and Gentlemen:

We have acted as counsel to Dynex Capital, Inc., a Virginia corporation (the “Company”), in connection with a registration statement filed on Form S-3 (as amended, the “Registration Statement”) by the Company with the U.S. Securities and Exchange Commission (“SEC”) under the Securities Act of 1933 (the “Securities Act”) on July 28, 2025, including a prospectus dated July 28, 2025, (the “Base Prospectus”), and a prospectus supplement to the Base Prospectus dated July 28, 2026 (the “Prospectus Supplement”) (such Prospectus Supplement together with the Base Prospectus, the “Prospectus”) relating to the offering from time to time of shares of the Company’s common stock, par value $0.01 per share (the “Shares”).

You have requested our opinion as to certain U.S. federal income tax matters regarding the Company. Although you may disclose to any and all persons, without limitation of any kind, this opinion, the U.S. federal tax treatment and federal tax structure of the Company and all materials of any kind that were provided to you by us relating to such tax treatment and tax structure, this opinion is intended solely for your benefit in connection with the offering of the Shares. You may not authorize any other person or entity to rely on this opinion, or otherwise make this opinion available for the benefit of any other person or entity, without our prior written consent.

In our capacity as counsel to the Company and for purposes of rendering this opinion, we have examined and relied upon the following, with your consent: (i) the Registration Statement, (ii) the Prospectus, (iii) a certificate executed by duly appointed officers of the Company (the “Officer’s Certificate”) setting forth certain factual representations, dated July 28, 2026, and (iv) such other documents as we have considered relevant to our analysis. In our examination of such documents, we have assumed the authenticity of original documents, the accuracy of copies, the genuineness of signatures, and the legal capacity of signatories. We have also assumed that all parties to such documents have acted, and will act, in accordance with the terms of such documents.

Our opinion is based on (a) our understanding of the facts as represented to us in the Officer’s Certificate and (b) the assumption that (i) the Company and its subsidiaries have valid legal existences under the laws of the states in which they were formed and have operated in accordance with the laws of such states, (ii) the Company is operated, and will continue to be operated, in the manner described in the Officer’s Certificate, (iii) the facts contained in the Officer’s Certificate, the Registration Statement and the Prospectus are true and complete in all material respects, (iv) all representations of fact contained in the Officer’s Certificate are true and complete in all material respects and (v) any representation of fact in the Officer’s Certificate that is made “to the knowledge of” or similarly qualified is correct without such qualification. While we have made such inquiries and investigations as we have deemed necessary, we have not undertaken any independent inquiry into

Dynex Capital, Inc.

July 28, 2026

or verification of all such facts either in the course of our representation of the Company or for the purpose of rendering this opinion. While we have reviewed all representations made to us to determine their reasonableness, we have no assurance that they are or will ultimately prove to be accurate.

We note that the tax consequences addressed herein depend upon the actual occurrence of events in the future, which events may or may not be consistent with any representations made to us for purposes of this opinion. In particular, the qualification and taxation of the Company as a real estate investment trust (“REIT”) for U.S. federal income tax purposes depends upon the Company’s ability to meet on a continuing basis certain distribution levels, diversity of stock ownership, and the various qualification tests imposed by the U.S. Internal Revenue Code of 1986, as amended (the “Code”). To the extent that the facts differ from those represented to or assumed by us herein, our opinion should not be relied upon.

Our opinion herein is based on existing law as contained in the Code, final and temporary Treasury Regulations promulgated thereunder, administrative pronouncements of the Internal Revenue Service (the “IRS”) and court decisions as of the date hereof. The provisions of the Code and the Treasury Regulations, IRS administrative pronouncements and case law upon which this opinion is based could be changed at any time, perhaps with retroactive effect. In addition, some of the issues under existing law that could significantly affect our opinion have not yet been authoritatively addressed by the IRS or the courts, and our opinion is not binding on the IRS or the courts. Hence, there can be no assurance that the IRS will not challenge, or that the courts will agree with, our conclusions.

Based upon, and subject to, the foregoing and the next paragraphs below, we are of the opinion that, as of the date hereof:

1.    The Company has been organized and has operated in conformity with the requirements for qualification and taxation as a REIT pursuant to Sections 856 through 860 of the Code for its taxable year ended December 31, 2022 through its taxable year ended December 31, 2025, and its current organization and current and proposed method of operation will enable it to continue to qualify for taxation as a REIT for its current taxable year ending December 31, 2026.

2.We have reviewed the statements included or incorporated by reference in the Prospectus under the heading “Material U.S. Federal Income Tax Considerations” and, although such discussion does not purport to summarize all possible U.S. federal income tax consequences of the purchase, ownership and disposition of the Shares, insofar as such discussion pertains to matters of law or legal conclusions, such discussion is correct in all material respects.

We undertake no obligation to update this opinion, or to ascertain after the date hereof whether circumstances occurring after such date may affect the conclusions set forth herein. We express no opinion as to matters governed by any laws other than the Code, the Treasury Regulations, published administrative announcements and rulings of the IRS, and court decisions.

This opinion is furnished to you solely for use in connection with the Registration Statement. We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 8-K of the Company and to such Registration Statement. We also consent to the reference to our firm name wherever appearing in the Registration Statement and the Prospectus. In giving this consent, we do not admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the SEC thereunder, nor do we thereby admit that we are experts with respect to any part of the Registration Statement within the meaning of the term “experts” as used in the Securities Act or the rules and regulations of the SEC promulgated thereunder.
