**EXPLANATORY NOTE**

This Post-Effective Amendment (the "Post-Effective Amendment") relates to the Registration Statement on Form S-8 (File No. 333-268634) (the "Registration Statement"), filed by Flagstar Financial, Inc. f/k/a New York Community Bancorp., Inc. (the "Predecessor") with the Securities and Exchange Commission (the "Commission").

The Registration Statement originally registered shares of common stock of Predecessor in connection with the merger completed on December 1, 2022. Pursuant to the Agreement and Plan of Merger dated April 24, 2021, as amended, by and among Predecessor, 615 Corp. ("Merger Sub"), and Flagstar Bancorp, Inc. ("FSBC"), Merger Sub merged with and into FSBC, with FSBC surviving (the "Merger"). Immediately following the Merger, FSBC merged with and into Predecessor, with Predecessor as the surviving entity. As a result, the Registration Statement registered: (i) 3,082,914 shares of Predecessor common stock issuable pursuant to awards outstanding under the Flagstar Bancorp, Inc. 2016 Stock Award and Incentive Plan ("Flagstar Stock Plan") at the effective time of the Merger; and (ii) 4,197,129 additional shares of Predecessor common stock that may be issued pursuant to awards granted under the Flagstar Stock Plan, as assumed by Predecessor, in accordance with and subject to the terms of Section 303A.08 of the NYSE Listed Company Manual. These additional shares represented the remaining number of FSBC common stock shares available for issuance under the Flagstar Stock Plan immediately prior to the Merger, adjusted appropriately to reflect the transaction.

This Post-Effective Amendment is being filed pursuant to Part 16 of the regulations promulgated by the Office of the Comptroller of the Currency (the "OCC"), including 12 C.F.R. § 16.15, to reflect the completion by the Predecessor of an internal reorganization to streamline and simplify its corporate structure (the "Reorganization"), pursuant to which the Predecessor merged with and into Flagstar Bank, National Association, a banking association organized under the laws of the United States (the "Issuer"), with the Issuer continuing as a publicly-traded company. In the Reorganization, which was completed on October 17, 2025, each share of the issued and outstanding common stock, $0.01 par value per share, of the Predecessor ("Predecessor Common Stock") was converted into one share of common stock, par value $0.01 per share, of the Issuer ("Issuer Common Stock"), having substantially the same rights, powers, preferences, qualifications, limitations and restrictions as the Predecessor Common Stock.

Pursuant to the Reorganization, the Issuer became the successor issuer to the Predecessor pursuant to Rule 12g-3 under the Securities and Exchange Act of 1934, as amended (the "Exchange Act").

In connection with the Reorganization, the Issuer assumed the Flagstar Stock Plan from the Predecessor. Each award under the Flagstar Stock Plan assumed by the Issuer is issuable upon the same terms and conditions as were in effect immediately prior to the completion of the Reorganization, except that all such awards under the Flagstar Stock Plan now entitle the holder thereof to acquire shares of common stock of the Issuer.

The Issuer, as the successor registrant to the Predecessor, hereby expressly adopts this registration statement as its own for all purposes of the Exchange Act and the regulations promulgated by the OCC contained in 12 C.F.R. Part 16.

**PART I** 

**INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS** 

All information required by Part I of this registration statement is omitted from this filing in accordance with the provisions of Rule 428 under the Securities Act of 1933, as amended (the "Securities Act") and the introductory note to Part I of Form S-8. The documents containing the information specified in Part I of Form S-8 will be delivered to the participants in the plan covered by this registration statement as specified by Rule 428(b)(1) of the Securities Act. These documents and the documents incorporated by reference into this registration statement pursuant to Part II, taken together, constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act.

**Item 4. Description of Securities** 

Not applicable.

**Item 5. Interests of Named Experts and Counsel** 

Not applicable.

**Item 6. Indemnification of Directors and Officers** 

The Issuer (also referred to in this Item 6 as the "Association") is a national banking association organized under the laws of the United States of America. Article TENTH of the Issuer's Amended and Restated Articles of Association, and Article VII of the

------

Issuer's Amended and Restated Bylaws, which are both included below, set forth the circumstances under which directors, officers, employees and agents of the Issuer may be insured or indemnified against liability which they incur in their capacities as such.

Article TENTH of the Issuer's Amended and Restated Articles of Association provides as follows:

TENTH. A director of the association shall not be personally liable to the association or its shareholders for damages for any breach of duty as a director, except to the extent that such exemption from liability or limitation thereof is not permitted under applicable law. No amendment, modification or repeal of this Article TENTH shall adversely affect any right or protection of a director that exists at the time of such amendment, modification or repeal.

The bank may make or agree to make indemnification payments to an institution-affiliated party, as defined at 12 USC 1813(u), for an administrative proceeding or civil action initiated by any federal banking agency, that are reasonable and consistent with the requirements of 12 USC 1828(k), 12 CFR 359, and 12 CFR 7.2014.

The bank may indemnify an institution-affiliated party, as defined at 12 USC 1813(u), for damages and expenses, including the advancement of expenses and legal fees, in cases involving an administrative proceeding or civil action not initiated by a federal banking agency, in accordance with the Delaware General Corporation Law, Del. Code Ann. Tit. 8 (1991, as amended 1994, and as amended thereafter), provided such payments are consistent with safe and sound banking practices.

The association may, upon affirmative vote of a majority of its board of directors, purchase and maintain insurance to indemnify its institution-affiliated parties, as defined at 12 U.S.C. § 1813(u), to the extent that such indemnification is allowed in these Articles of Association or the Bylaws; provided, however, that no such insurance shall include coverage for the cost of any judgment or civil money penalty assessed against such person in an administrative proceeding or civil action commenced by any federal banking agency. Such insurance may, but need not, be for the benefit of all institution-affiliated parties.

If this Article TENTH or any part hereof, shall be held unenforceable in any respect by a court of competent jurisdiction, it shall be deemed modified to the minimum extent necessary to make it enforceable, and the remainder of this Article TENTH shall remain fully enforceable.

Article VII of the Issuer's Amended and Restated Bylaws provides as follows:

Section 7.01 <u>Indemnification</u>. Except as provided in Section 7.03 of these Bylaws, the Association shall, to the maximum extent permitted, indemnify an individual made a party to a proceeding because he or she is or was an institution-affiliated party, as defined at 12 U.S.C. § 1813(u) (an "Institution-Affiliated Party"), against liability incurred in the proceeding if his or her conduct was in good faith, he or she reasonably believed that his or her conduct was in, or not opposed to, the Association's best interests, and in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. Termination of the proceeding by judgment, order, settlement, conviction, upon a plea of nolo contendere or its equivalent, is not, of itself, determinative that the Institution-Affiliated Party did not meet the standard of conduct described in this Section 7.01.

Section 7.02 <u>Banking Agency Proceedings or Actions</u>. The Association shall make or agree to make indemnification payments to an Institution-Affiliated Party for an administrative proceeding or civil action initiated by any Federal banking agency, that are reasonable and consistent with the requirements of 12 U.S.C. § 1828(k) and its implementing regulations. The Association shall indemnify an Institution-Affiliated Party for damages and expenses, including the advancement of expenses and legal fees, in cases involving an administrative proceeding or civil action not initiated by a Federal banking agency, in accordance with applicable law; provided, that such payments are consistent with safe and sound banking practices.

Section 7.03 <u>Certain Restrictions on Indemnification</u>. The Association may not indemnify an Institution-Affiliated Party in connection with a proceeding by or in the right of an Association in which such Institution-Affiliated Party was adjudged liable to the Association, or in connection with any other proceeding charging that such party derived an improper personal benefit, whether or not involving action in his or her official capacity, in which proceeding he or she was adjudged liable on the basis that he or she derived an improper personal benefit.

Section 7.04 <u>Mandatory Indemnification</u>. Subject to the restrictions in Section 7.03 above, the Association shall indemnify a director or officer of the Association who was successful, on the merits or otherwise, in the defense of any proceeding, or in the defense of any claim, issue or matter in the proceeding, to which he or she was a

------

party because he or she is or was a director or officer of the Association, against reasonable expenses incurred by him or her in connection with the proceeding or claim with respect to which he or she has been successful.

Section 7.05 <u>Determination</u>. The Association may not indemnify an Institution-Affiliated Party under Section 7.01 of these Bylaws unless authorized and a determination has been made in a specific case that indemnification of the Institution-Affiliated Party is permissible in the circumstances because the Institution-Affiliated Party has met the applicable standard of conduct set forth in Section 7.01 of these Bylaws. Such determination shall be made either (a) by the Board of Directors or their designee in accordance with applicable law, or (b) by the holders of common stock of the Association, by a majority of the votes entitled to be cast by holders of qualified shares present in person or by proxy at a meeting. The majority of the votes entitled to be cast by the holders of all qualified shares constitute a quorum for purposes of action that complies with this Section 7.05.

Section 7.06 <u>General Indemnification</u>. The indemnification and advancement of expenses provided by this Article VII shall not be construed to be exclusive of any other rights to which a person seeking indemnification or advancement of expenses may be entitled under the Articles of Association, these Bylaws, any agreement, any vote of shareholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office.

Section 7.07 <u>Advances</u>. The Association, in accordance applicable law, shall pay for or reimburse the reasonable expenses incurred by an Institution-Affiliated Party who is a party to a proceeding in advance of final disposition of the proceeding if (a) such party furnishes the Association a written affirmation of his or her good faith belief that he or she has met the applicable standard of conduct described in Section 7.01 of these Bylaws, (b) such party furnishes to the Association a written undertaking in the form required by applicable law, executed personally or on his or her behalf, to repay the advance if it is ultimately determined that he or she did not meet the applicable standard of conduct and (c) a determination is made that the facts then known to those making a determination would not preclude indemnification under this Article VII.

Section 7.08 <u>Scope of Indemnification</u>. Except as otherwise provided in these Bylaws, the indemnification and advancement of expenses authorized by this Article VII are intended to permit the Association to indemnify to the fullest extent permitted by applicable law, any and all persons whom it shall have power to indemnify under applicable law from and against any and all of the expenses, liabilities or other matters referred to in or covered by such laws. Any indemnification or advancement of expenses hereunder shall, unless otherwise provided when the indemnification or advancement of expenses is authorized or ratified, continue as to a person who has ceased to be an Institution-Affiliated Party and shall inure to the benefit of such person's heirs, executors and administrators.

Section 7.09 <u>Insurance</u>. The Association may provide for the payment of reasonable premiums for insurance on behalf of a person who is or was an Institution-Affiliated Party, or who, while serving as an Institution-Affiliated Party, is or was serving at the request of the Association as a director, officer, partner, trustee, employee, fiduciary, or agent of another foreign or domestic Association, or other person, or of an employee benefit plan, against liability asserted against or incurred by him or her in any such capacity or arising out of his or her status in any such capacity, whether or not the Association would have the power to indemnify him or her against the liability under the provisions of this Article VII or applicable law, as the same may hereafter be amended or modified; provided, that such liability insurance shall be consistent with the requirements of 12 C.F.R. 7.2014 and shall exclude coverage of liability for a formal order assessing civil money penalties against an Institution-Affiliated Party.

Section 7.10 <u>Reliance Upon Corporate Records</u>. Each director and officer and each member of any committee designated by the Board of Directors shall, in the performance of his or her duties, be fully protected in relying in good faith upon the books of account or other records of the Association or of any of its subsidiaries, or upon information, opinions, reports or statements made to the Association or any of its subsidiaries by any officer or employee of the Association or of a subsidiary or by any committee designated by the Board of Directors or by any other person as to matters such director, officer or committee member reasonably believes are within such other person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Association.

------

Section 7.11 <u>Other Rights and Remedies</u>. The rights to indemnification and advancement of expenses provided in this Article shall be in addition to any other rights which a party may have or hereafter acquire under any applicable law, contract, order or otherwise.

Section 7.12 <u>Severability</u>. If any provision of this Article VII shall be held to be invalid, illegal or unenforceable for any reason, the remaining provisions of this Article VII shall not be affected or impaired thereby, but shall, to the fullest extent possible, be construed so as to give effect to the intent of this Article VII that each party covered hereby is entitled to the fullest protection permitted by applicable law.

**Item 7. Exemption from Registration Claimed** 

Not applicable.

**Item 8. Exhibits** 

For the list of exhibits, see the Exhibit Index to this Post-Effective Amendment, which is incorporated herein by reference.

**Item 9. Undertakings** 

(a)&nbsp;&nbsp;&nbsp;&nbsp;The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;&nbsp;&nbsp;&nbsp;To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;To include any prospectus required by Section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the registration statement;

*provided, however*, that paragraphs (a)(1)(i) and (a)(1)(ii) above shall not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;&nbsp;&nbsp;&nbsp;That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;&nbsp;&nbsp;&nbsp;To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)&nbsp;&nbsp;&nbsp;&nbsp;The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the

------

Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
