 Exhibit 4.3 

This Supplemental Indenture (this “Supplemental Indenture”), dated as of July 31, 2018 among WMIH Corp, a Delaware

“Issuers”) and Wells Fargo Bank, National Association, as trustee (the “Trustee”). 

W I T N E S S E T H 

WHEREAS, the Issuers and each of the Guarantors (as defined in the Indenture referred to below) have heretofore executed and delivered to the
Trustee an indenture (the “Indenture”), dated as of May 31, 2013, providing for the issuance of 6.500% Senior Notes due 2022 (the “Notes”); 

WHEREAS, the Guaranteeing Parent has determined that it is desirable to unconditionally guarantee all of the Issuers’ Obligations under
the Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Note Guarantee”) and the provision of the Note Guarantee is permitted pursuant to Section 9.01 of the
Indenture; and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and
deliver this Supplemental Indenture. 
 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the
receipt of which is hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 

(1)    Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them
in the Indenture. 
 (2)    Agreement to Guarantee. The Guaranteeing Parent hereby agrees as follows: 

(a) Along with all other Guarantors named in the Indenture (including pursuant to any supplemental indentures), to jointly and severally
unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its respective successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the
obligations of the Issuers hereunder or thereunder, that: 
 (i) the principal of, interest and premium, if any, on the Notes
shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or
the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be
promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. 







 Failing payment when due of any amount so guaranteed or any performance so guaranteed for
whatever reason, the Guarantors and the Guaranteeing Parent shall be jointly and severally obligated to pay the same immediately. This is a guarantee of payment and not a guarantee of collection. 

(b) The obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes
or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers or any Guarantors, any action to
enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 

(c) The Guaranteeing Parent hereby waives: diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever. 

(d) This Note Guarantee shall not be discharged except by full payment or complete performance of the obligations contained in
the Notes, the Indenture and this Supplemental Indenture, and the Guaranteeing Parent accepts all obligations of a Guarantor under the Indenture, including Article X of the Indenture (which is deemed incorporated in this Supplemental Indenture and
applicable to this Note Guarantee). The Guaranteeing Parent acknowledges that by executing this Supplemental Indenture, it will become a Guarantor under the Indenture and subject to all the terms and conditions applicable to Guarantors contained
therein. 
 (e) If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors
(including the Guaranteeing Parent), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the Trustee or such Holder, this Note Guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect. 
 (f) The Guaranteeing Parent shall not be entitled to
any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 

(g) As between the Guaranteeing Parent, on the one hand, and the Holders and the Trustee, on the other hand, (x) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI of the Indenture for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of
the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article VI of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable
by the Guaranteeing Parent for the purpose of this Note Guarantee.

 (h) The Guaranteeing Parent shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under this Note Guarantee. 

(i) Pursuant to Section 10.02 of the Indenture, the obligations of the Guaranteeing Parent shall be
limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guaranteeing Parent that are relevant under any applicable Bankruptcy Law or fraudulent conveyance laws and
after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article X of the Indenture, result in the
obligations of such Guaranteeing Parent under this Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. 

(j) This Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or
against the Issuers for liquidation, reorganization, should the Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuers’ assets, and
shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes and Note Guarantee, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any
payment or any part thereof, is rescinded, reduced, restored or returned, the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(k) In case any provision of this Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 (l) This Note Guarantee
shall be a general unsecured senior obligation of such Guaranteeing Parent, ranking pari passu with any other future unsubordinated Indebtedness of the Guaranteeing Parent, if any. 

(m) Each payment to be made by the Guaranteeing Parent in respect of this Note Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 

(3)    Execution and Delivery. The Guaranteeing Parent agrees that the Note Guarantee shall remain in full force
and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

 (4)    Merger, Consolidation or Sale of All or Substantially All
Assets. 
 (a) The Guaranteeing Parent may not sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guaranteeing Parent is the surviving Person), another Person, other than the Issuers or another Guarantor, unless: 

(i) except in the case of a merger entered into solely for the purpose of reincorporating a Guaranteeing Parent in another
jurisdiction, immediately after giving effect to that transaction, no Default or Event of Default shall have occurred and be continuing; and 

(ii) either: 

(A) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger (if not the Guaranteeing Parent) assumes all the obligations of that Guaranteeing Parent under the Indenture and its Note Guarantee pursuant to this supplemental indenture; or 

(B) the Net Proceeds of such sale or other disposition are either (i) applied in accordance with
Section 4.10(d) of the Indenture or (ii) not required to be applied in accordance with any provision of the Indenture. 

(5)    Releases. 

The Note Guarantee of the Guaranteeing Parent shall be automatically and unconditionally released and discharged, and no further action by the
Guaranteeing Parent, the Issuers or the Trustee is required for the release of the Guaranteeing Parent’s Note Guarantee, in the following circumstances: 

(a) in connection with any sale, transfer or other disposition of all or substantially all of the assets of that Guaranteeing
Parent (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate
Section 4.10 of the Indenture; 
 (b) in connection with any sale, transfer or other disposition of
all of the Capital Stock of the Guaranteeing Parent (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale
or other disposition does not violate Section 4.10 of the Indenture; 
 (c) if the Company
designates any Restricted Subsidiary of the Company that is a Guarantor to be an Unrestricted Subsidiary of the Company in accordance with Section 4.17 of the Indenture; or 

(d) upon the exercise of Legal Defeasance by the Issuers or pursuant to Article XI of the Indenture; and 

in connection with such release, either of the Issuers shall deliver to the Trustee an Officers’ Certificate of such Guarantor confirming
the effective date of such release and stating that all conditions precedent provided for in this Indenture relating to such transaction have been complied with.

incorporator or stockholder of the Guaranteeing Parent shall have any liability for any obligations of the Issuers or the Guarantors (including the Guaranteeing Parent), respectively, under the Notes, the Note Guarantees, the Indenture or this
Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation; provided that the foregoing shall not limit any Guarantor’s obligations under its Note Guarantees. Each Holder by
accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

occurred and is continuing, the Guaranteeing Parent shall not be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuers under the Indenture or the
Notes shall have been paid in full.

Guarantee is subject to the terms and conditions set forth in the Indenture. The Guaranteeing Parent acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and this Supplemental
