Each Contributor acknowledges that the SOF GPs will be entitled to a one-time carried interest distribution made in cash pursuant to the SOF Agreements upon the occurrence of LibreMax Asset-Backed Income Fund's (the "**Fund**") acquisition of the assets of the Fund I Non-ECI Master Fund, LibreMax Structured Opportunities (ECI) Master Fund I, LP, LibreMax Structured Opportunities Master Fund II, LP and LibreMax Structured Opportunities (ECI) Master Fund I, LP in exchange for Class I voting common shares in the Fund, which such transaction shall be made in accordance with the agreement and plan of exchange, dated as of April 30, 2026. Each Contributor acknowledges it will indirectly bear such carried interest allocation to the SOF GPs described in the preceding sentence through its ABIF Interests.

------

#### Re: LibreMax Asset-Backed Income Fund

Ladies and Gentlemen:

This letter agreement (this "***Agreement***") is effective as of April 30, 2026 (the "***Effective Date***"), by and between ICONIQ Capital, LLC ("***ICONIQ Capital***"), Glide Path Solutions 2024 LP ("***GPS 2024***"), Glide Path Solutions 2025 LP ("***GPS 2025***"), and Glide Path Solutions 2026 LP ("***GPS 2026***", and together with GPS 2024 and GPS 2025, the "***ICONIQ Funds***", and the Funds collectively with ICONIQ Capital, "***ICONIQ***") and LibreMax Capital, LLC, a Delaware limited liability company (the "***Investment Manager***" and, together with ICONIQ, each, a "***Party***" and, collectively, the "***Parties***"), is being entered into in connection with (i) ICONIQ's conversion of Feeder Interests (as defined below) into ABIF Interests (as defined below) in accordance with the Contribution and Distribution Agreement (as defined below), and (ii) the ABIF Fund's (as defined below) receipt of Class I Common Shares in LibreMax Asset-Backed Income Fund (the "***Fund***"), a non-diversified, closed-end management investment company registered with the Securities and Exchange Commission.

<u>Preliminary Statement</u>

WHEREAS, the Investment Manager is the manager of (i) LibreMax Structured Opportunities (ECI) Master Fund I, LP (the "***Fund I ECI Master Fund***"), (ii) LibreMax Structured Opportunities Master Fund I, LP (the "***Fund I Non-ECI Master Fund***" and together with the Fund I ECI Master Fund, the "***Fund I Master Funds***"), (iii) LibreMax Structured Opportunities (ECI) Master Fund II, LP (the "***Fund II ECI Master Fund***"), (iv) LibreMax Structured Opportunities Master Fund II, LP (the "***Fund II Non-ECI Master Fund***" and together with the Fund II ECI Master Fund, the "***Fund II Master Funds***") (the Fund I Master Funds and the Fund II Master Funds, the "***Master Funds***" and, together with the Fund, the "***Funds***"), (v) the Fund I Feeders (as defined below), (vi) the Fund II Feeders (as defined below), and (vii) LibreMax ABIF Partners, LP (the "***ABIF Fund***");

WHEREAS, the Fund will acquire substantially all of the assets of the Master Funds as seed portfolio investments of the Fund pursuant to an agreement and plan of exchange (the "***Plan of Exchange***");

WHEREAS, ICONIQ's existing investments in (i) LibreMax Structured Opportunities Partners I, LP ("***Onshore Feeder Fund I***"), (ii) LibreMax Structured Opportunities Offshore Partners I, LP ("***Offshore Feeder Fund I***" and together with the Onshore Feeder Fund I, the "***Fund I Feeders***", which invest, directly or indirectly, in the Fund I Master Funds), (iii) LibreMax Structured Opportunities Partners II, LP ("***Onshore Feeder Fund II***"), and (iv) LibreMax Structured Opportunities Offshore Partners II, LP ("***Offshore Feeder Fund II***" and together with the Onshore Feeder Fund II, the "***Fund II Feeders***", which invest, directly or indirectly, in the Fund II Master Funds) (the interests in the Fund I Feeders and the Fund II Feeders, the "***Feeder Interests***"), will be contributed to the ABIF Fund immediately prior to the Plan of Exchange and ICONIQ will be distributed corresponding interests in the ABIF Fund (the "***ABIF Interests***") in accordance with that certain contribution and distribution agreement (the "***Contribution and Distribution Agreement***"), followed by the ABIF Fund receiving an interest in the Fund upon the occurrence of the Plan of Exchange; and

WHEREAS, ICONIQ's indirect holding of Feeder Interests (held through its ABIF Interests) will convert into indirect holdings of Class I Common Shares of the Fund (the "***Initial Exchange Shares***") in exchange for ICONIQ being provided certain rights pursuant to a collaborative and strategic relationship agreement (the "***SRA***"), which the Parties agree will be subject to a Lock-Up (as defined below) under the terms set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual promises of the Parties, and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, it is mutually agreed by and among the Parties hereto as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1. <u>Lock-Up Period</u>**. The Parties agree that in acknowledgement of the certain rights provided to ICONIQ under the SRA, and notwithstanding that the Fund may offer all of its shareholders the opportunity to repurchase their shares, for a period of six (6) months following the date that the ICONIQ Funds receive their indirect interests in Class I Common Shares of the Fund through receiving ABIF Interests, ICONIQ Capital shall not exercise any withdrawal rights under the First Amended and Restated Limited Partnership Agreement of ABIF Fund (the "***ABIF Fund Partnership Agreement***"***)*** on behalf of the ICONIQ Funds and shall not exercise any right on behalf of the ICONIQ Funds to have their indirect holdings of Class I Common Shares repurchased on the same terms as offered by the Fund in any repurchase offer (the "***Lock-Up***"). ICONIQ agrees and acknowledges that the entitlements provided to it pursuant to the SRA are subject to the ICONIQ Funds (i) maintaining their indirect holdings of the Initial Exchange Shares through their ABIF Interests through the Lock-Up and (ii) not withdrawing or transferring their interest in the Fund held through their ABIF Interests prior to the expiration of the Lock-Up.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2. <u>Voting</u>**. For the avoidance of doubt, all voting rights in respect of any Fund-related matter, including those enumerated in Section 16.13 of the ABIF Fund Partnership Agreement, attributable to the ABIF Interests held by the ICONIQ Funds shall be exercisable exclusively by ICONIQ Capital.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3. <u>Governing Law</u>**. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware as applied to agreements among Delaware residents made and to be performed entirely within Delaware, without giving effect to the principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of the laws of another jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4. <u>Conflict</u>**. In the event of a conflict between the provisions of this Agreement and those of the SRA to which ICONIQ and the Investment Manager are parties, the provisions of this Agreement shall control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5. <u>Termination</u>**. This Agreement shall terminate upon the earlier of (i) the agreement of all Parties in writing or (ii) pursuant to the SRA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6. <u>Miscellaneous</u>**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each of the Parties hereto has full power, authority and capacity to enter into this Agreement and to take actions necessary for itself to comply with all of the terms of, and all of its obligations under this Agreement, and taking such actions does not conflict with, or constitute a default under, any instruments governing such party, any law, regulation or order, or any agreement to which such Party is a Party or by which such party may be bound.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) This Agreement may be executed in any number of counterparts and by the different Parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, and all of which taken together shall constitute one and the same agreement with the same effect as if such signatures were upon the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) This Agreement may not be assigned or transferred by any party hereto without the prior written consent of all Parties hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Neither the failure nor any delay on the part of any party hereto to exercise any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right preclude any other or further exercise of the same or any other rights, nor shall any waiver of any rights with respect to any occurrence be construed as a waiver of such right with respect to any other occurrence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) With respect to ICONIQ, this Agreement supplements the terms of, or confirms the interpretation of the SRA and the Contribution and Distribution Agreement and contains the entire understanding among the Parties hereto with respect to the subject matter hereof and supersedes all prior or contemporaneous negotiations, covenants, agreements, representations, warranties, undertakings, and understandings, written or oral, and courses of conduct and dealing between the Parties hereto with respect to the subject matter hereof.

**Exhibit 99.4**<br>

#### AMENDED AND RESTATED VOTING TRUST AGREEMENT
**THIS AMENDED AND RESTATED VOTING TRUST AGREEMENT** (this "**Agreement**") amends and restates in its entirety that certain Voting Trust Agreement dated as of February 24, 2026 (the "**Original Agreement**"), by and among CSC Delaware Trust Company, as trustee (the "**Trustee**" or any successor thereto), ICONIQ Capital, LLC, including its successors and assigns by operation of law (the "**Purchaser**") and Glass, Lewis & Co., LLC (the "**Voting Consultant**" or any successor thereto) and is effective for all purposes and in all respects as of April 2, 2026.

**WHEREAS**, the Purchaser, the Trustee, and the Voting Consultant entered into the Original Agreement pursuant to which the Purchaser transferred and assigned to the Trustee certain voting and consent rights with respect to common shares of the Fund (as defined below) held for the accounts of the Clients (as defined below);

**WHEREAS**, the parties desire to amend and restate the Original Agreement in its entirety to reflect certain changes to the structure of the Clients' investment in the Fund;

**WHEREAS**, the Purchaser is or will be the Beneficial Owner of limited partnership interests (the "**Interests**") of LibreMax ABIF Partners, LP (the "**Partnership**") held for the accounts of investment management clients of the Purchaser, including Glide Path Solutions 2024 LP ("**GPS 2024**"), Glide Path Solutions 2025 LP ("**GPS 2025**"), and Glide Path Solutions 2026 LP ("**GPS 2026**", and together with GPS 2024 and GPS 2025, the "**Clients**") pursuant to the terms of the Subscription Agreements among the Clients and the Partnership (the "**Subscription Agreements**");

**WHEREAS**, the Partnership will invest all of its assets in common shares (the "**Shares**") of LibreMax Asset-Backed Income Fund (the "**Fund**");

**WHEREAS,** under the terms of the limited partnership agreement (the "**LPA**") of the Partnership, the Clients, and therefore the Purchaser, shall be entitled to instruct the general partner (the "**Partnership GP**") of the Partnership as to how to vote the portion of the Partnership's interest in the Fund that is attributable to the Clients' Interests;

**WHEREAS**, the Purchaser desires to transfer and assign irrevocably to the Trustee, and the Trustee desires to accept such transfer and assignment of, the Purchaser's right to instruct the Partnership GP on how to vote or consent the portion of the Partnership's interest in the Fund that is attributable to the Clients' Interests in connection with the Voting Matters (as defined below) as the Beneficial Owner of (i) Interests acquired by the Clients pursuant to the Subscription Agreements (such Interests, when beneficially owned by the Purchaser, the "**Subject Interests**") and (ii) any additional Interests of which the Purchaser becomes the Beneficial Owner of during the term of this Agreement (any such additional Interests when so acquired and when beneficially owned by the Purchaser will become a part of the "Subject Interests" covered by this Agreement);

**WHEREAS**, the Voting Consultant shall analyze the Voting Matters requiring the owner of Subject Interests to instruct the Partnership GP on how to vote or consent, and shall provide a recommendation to the Trustee on how to instruct the Partnership GP to vote or consent with respect to such Voting Matters;

**WHEREAS**, the parties acknowledge that, pursuant to the LPA, instructions delivered by the Trustee to the Partnership GP on behalf of the Purchaser with respect to the Subject Interests shall constitute valid instructions of the Purchaser for purposes of the LPA, and that the Partnership GP shall be entitled to rely on such instructions;

**WHEREAS**, the Voting Consultant and the Trustee are each Independent of the Purchaser; and

**WHEREAS**, the parties hereto desire to set forth in writing their understandings and agreements.

**NOW, THEREFORE**, in consideration of the foregoing, of the mutual promises hereinafter set forth and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties, intending legally and equitably to be bound, hereby agree as follows:

**1. Creation of Trust**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Purchaser hereby irrevocably transfers and assigns to the Trustee, and the Trustee hereby accepts the transfer and assignment of, the right to instruct the Partnership GP to vote and consent on behalf of the Purchaser in connection with all of its voting and consent rights and responsibilities as Beneficial Owner of the Subject Interests with respect to any matters that holders of Shares are entitled to vote on that would cause the Shares to constitute "voting securities" under the Investment Company Act of 1940, as amended (the "**1940 Act**"), including but not limited to the election of trustees to the Board of Trustees of the Fund (collectively, the "**Voting Matters**"). For the avoidance of doubt, matters that are presented to the Purchaser in connection with voting and consent rights afforded to the shareholders of the Fund that do not constitute "voting rights" under the 1940 Act, shall not be transferred to the Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In order to effect the transfer of voting and consent rights, including the right to deliver voting instructions with respect to the Voting Matters, the Purchaser hereby irrevocably appoints and constitutes the Trustee as its attorney-in-fact and grants the Trustee one or more irrevocable proxies with respect to delivering voting instructions to the Partnership GP on the Purchaser's behalf with respect to the Voting Matters, and further agrees to renew any such proxies that may lapse by their terms while the Subject Interests are still subject to this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Clients will be the registered owners of the Subject Interests. If any dividend or other distribution in respect of the Subject Interests is paid, such dividend or distribution will be paid directly to the Clients.

------

**2. Definitions**

"**Beneficial Owner**" means, any Person who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares (i) voting power which includes the power to vote, or to direct the voting of, securities and/or (ii) investment power which includes the power to dispose, or to direct the disposition of, securities.

"**Board of Trustees**" means the Board of Trustees of the Fund or any duly authorized committee thereof.

"**Independent**" means, as to any Person, any other Person who (i) does not have and is not committed to acquire any material direct or any material indirect financial interest in such Person, (ii) is not connected with such Person as an officer, employee, promoter, underwriter, partner, director or Person performing similar functions and (iii) is not otherwise subject to the undue influence or control of such other Person. For purposes of this definition, no Person will fail to be Independent solely because such Person acts as a voting consultant or trustee in respect of property owned by another Person or its affiliates pursuant to this Agreement or any other agreement. With respect to item (i) above, "material direct or material indirect financial interest" means, (1) as to any Person, owning directly or indirectly (as principal for such Person's own account) at least 5% of any class of the outstanding equity or debt securities issued by any other Person or (2) with respect to a Person (the "**Investor**") owning directly or indirectly (as principal for the Investor's own account) outstanding equity or debt securities of any other Person in an amount at least equal to 5% of the total consolidated shareholders equity of the Investor (measured in accordance with U.S. generally accepted accounting principles).

"**Person**" means and includes an individual, a partnership, a corporation, a trust, an unincorporated association, a joint venture or other entity or a government or any agency or political subdivision thereof.

**3. Right to Transfer**

The Purchaser shall have the right to sell or otherwise transfer the Subject Interests at any time in its sole discretion, subject to the transfer restrictions contained in the LPA, the Subscription Agreement and applicable law. Upon the transfer of the Subject Interests by the Purchaser, except at set forth in Section 20 of this Agreement, such Subject Interests shall no longer be subject to this Agreement.

**4. Trustee**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Rights and Powers of Trustee**. With respect to Subject Interests, the Trustee shall, in person or by nominees, agents, attorneys-in-fact, or proxies, have the right and the obligation to exercise its discretion and deliver voting instructions to the Partnership GP with respect to all Voting Matters requiring holders of Shares to vote or consent, with respect to and including voting or consenting to any corporate or shareholder action of any kind whatsoever, subject to the terms of this Agreement. The Trustee shall be obligated to deliver such voting instructions to the Partnership GP in accordance with the provisions of this Agreement. This Agreement expressly and exclusively sets forth the duties of the Trustee with respect to any and all matters pertinent hereto and no implied duties or obligations shall be read into this Agreement against the Trustee. No provision of this Agreement shall require the Trustee to risk or advance its own funds or otherwise incur any financial liability or potential financial liability in the performance of its duties or the exercise of its rights under this Agreement. The Trustee shall not be obligated to take any legal action or to commence any proceedings in connection with this Agreement or any property held hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Liability of Trustee**. In exercising the rights and powers of the Trustee, the Trustee will exercise any rights and powers in the Trustee's best judgment; *provided*, *however*, the Trustee shall not be liable for any action taken by such Trustee or the Trustee's agent, except for liability arising from the Trustee's bad faith, willful misconduct or gross negligence. The Trustee shall not be required to give any bond or other security for the discharge of the Trustee's duties. In no event shall the Trustee be liable for incidental, indirect, special, consequential or punitive damages of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Resignation of and Successor Trustee**. The Trustee may at any time resign the Trustee's Position as Trustee by delivering a resignation in writing to the Purchaser and the Voting Consultant to become effective 90 days after the date of such delivery, but in any event such notice shall not become effective prior to the acceptance of a successor Trustee. The Trustee shall nominate a successor Trustee acceptable to the Purchaser, who shall have all rights, powers and obligations of the resigning Trustee as set forth in this Agreement, and all rights, powers and obligations of the resigning Trustee hereunder shall immediately terminate upon the acceptance by the successor Trustee of such nomination and the execution of this Agreement by the successor Trustee as "Trustee" hereunder. The Trustee shall have no responsibility for the appointment of a successor Trustee hereunder. If the Trustee shall resign but a successor Trustee has not assumed all of the Trustee's duties and obligations within 90 days of such resignation, the Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. No such resignation shall become effective until such time as a successor Trustee has been appointed and such appointment has been accepted. The fact that any Trustee has resigned such Trustee's position as a Trustee shall not act, or be construed to act, as a release of any Subject Interests from the terms and provisions of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) **Removal**. The Trustee may be removed by the Purchaser upon 30 days prior written notice upon either (i) a material breach by the Trustee of its obligations hereunder or (ii) any action or inaction of the Trustee which constitutes bad faith, gross negligence or willful misconduct in the performance of its obligations hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Contract**. A separate contract, that certain letter agreement between the Purchaser and the Trustee dated as of February 11, 2026, as may be amended from time to time (the "**Letter Agreement**"), sets forth additional details, including fees, pursuant to which the Trustee is providing the services contemplated hereunder**.**

**** 

<br> ------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) **Independent**. The Trustee represents that it is Independent of the Purchaser; *provided*, *however*, if the Trustee becomes aware that the Trustee is no longer Independent of the Purchaser, the Trustee shall promptly, and in no event later than two (2) business days after becoming aware, notify the Purchaser and shall abstain from voting or consenting during any period of time during which the Trustee is not Independent of the Purchaser. If the Trustee notifies the Purchaser that it is no longer Independent of the Purchaser, the Purchaser shall use commercially reasonable efforts to identify and appoint a replacement trustee.

**5. Voting Consultant**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Liability of Voting Consultant**. In providing its voting recommendations on Voting Matters hereunder, the Voting Consultant will provide such recommendations in the Voting Consultant's best judgment with respect to the Voting Matters for the Subject Interests; *provided*, *however*, the Voting Consultant shall not be liable for any action taken by such Voting Consultant or the Voting Consultant's agent, except for liability arising from the Voting Consultant's bad faith, willful misconduct or gross negligence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Resignation of and Successor Voting Consultant**. The Voting Consultant may at any time resign the Voting Consultant's Position as Voting Consultant by delivering a resignation in writing to the Purchaser and to the Trustee to become effective 90 days after the date of such delivery. Upon receipt of the Voting Consultant's written resignation, the Purchaser shall use commercially reasonable efforts to appoint a successor Voting Consultant which has been consented to by the Trustee, such consent not to be unreasonably withheld. If the Voting Consultant shall resign but a successor Voting Consultant has not assumed all of the Voting Consultant's duties and obligations within 90 days of such resignation, the Voting Consultant may Petition any court of competent jurisdiction for the appointment of a successor Voting Consultant. No such resignation shall become effective until such time as a successor Voting Consultant has been appointed and such appointment has been accepted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Removal**. The Voting Consultant may be removed by the Purchaser upon 30 days prior written notice upon either (i) a material breach by the Voting Consultant of its obligations hereunder or (ii) any action or inaction of the Voting Consultant which constitutes bad faith, gross negligence or willful misconduct in the performance of its obligations hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) **Agreement**. A separate consulting agreement by and between the Voting Consultant and the Purchaser, as may be amended from time to time with the prior written consent of the parties thereto (the "**Consulting Agreement**"), sets forth additional details, including fees, pursuant to which the Voting Consultant is providing the services contemplated hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Independent**. The Voting Consultant represents that it is Independent of the Purchaser; *provided*, *however*, if the Voting Consultant becomes aware that the Voting Consultant is no longer Independent of the Purchaser, the Voting Consultant shall promptly, and in no event later than two (2) business days after becoming aware, notify the Purchaser and shall abstain from making voting recommendations during any period of time during which the Voting Consultant is not Independent of the Purchaser. If the Voting Consultant notifies the Purchaser that it is no longer Independent of the Purchaser, the Purchaser shall use commercially reasonable efforts to identify and appoint a replacement voting consultant.

**6. Amount of Subject Interests Notification**

On any and each date that the Purchaser sells or otherwise transfers any Subject Interests to another Beneficial Owner, the Purchaser shall promptly notify the Trustee of such occurrence and the number of Shares that the Purchaser then owns.

**7. Voting Communications**

The Purchaser shall notify the Trustee and the Voting Consultant as soon as possible, and in any event, not later than two (2) business days after receipt of notice that a vote of the holders of Shares has been requested or permitted on any Voting Matter and the Purchaser shall, within such same time frame, forward any information sent to the Purchaser or the Clients in connection with such vote to the Trustee and the Voting Consultant.

The Voting Consultant shall analyze and provide a voting or consent recommendation to the Trustee with respect to each Voting Matter in respect of the Subject Interests; *provided* that if the Voting Consultant does not believe, utilizing its commercially reasonable discretion, that it is qualified to perform the analysis of any voting or consent action required by Section l(a) of this Agreement, the Voting Consultant shall refrain from making a voting or consent recommendation and provide notice to the Trustee and the Purchaser of such determination. The Trustee is obligated to act in accordance with the voting or consent recommendation made by the Voting Consultant in its voting or consent direction to the Purchaser. In all Voting Matters, the Trustee shall use the proxies granted to it by the Purchaser to instruct the Partnership GP on how to vote the Interests in accordance with the voting or consent recommendation made by the Voting Consultant and the Purchaser shall not exercise any voting or consent rights in such matters.

If the Voting Consultant fails to provide a voting or consent recommendation to the Trustee on or prior to the deadline for Submission of such vote or consent, the Trustee shall not provide a voting instruction to the Partnership GP on behalf of the Purchaser on such deadline and shall provide notice of the failure to receive a voting or consent recommendation to the Purchaser and the Voting Consultant. For the avoidance of doubt, the Purchaser shall not retain the right to instruct the Partnership GP on how to vote or consent on any Voting Matters for which the Trustee does not provide a voting instruction on behalf of the Purchaser.

------

**8. Indemnification**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Of the Purchaser and the Trustee.** The Voting Consultant shall indemnify and hold the Purchaser and the Trustee and the Purchaser's and the Trustee's duly authorized agents harmless from and against any and all liabilities, obligations, losses, damages, penalties, taxes, claims, actions, suits, reasonable costs, reasonable expenses or disbursements (including reasonable legal fees and expenses) of any kind and nature whatsoever and whether asserted by any party hereto or any third party which may be imposed, incurred or asserted against the Purchaser or the Trustee in connection with the bad faith, willful misconduct or gross negligence of the Voting Consultant in connection with the exercise of any powers or the performance of any duties by the Voting Consultant as herein provided or contemplated, including, without limitation, any action taken or omitted to be taken, except, with respect to the Purchaser and the Trustee separately, such as may arise from the bad faith, willful misconduct or gross negligence of the Purchaser or the Trustee, respectively. In no event shall the Voting Consultant be liable for special, incidental, indirect or consequential damages. The terms of this indemnification shall survive the termination of this Agreement or the resignation or removal of the Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Conditions to Indemnification**. An indemnified party must give the other party(ies) prompt written notice of any claim and allow the indemnifying party to defend or settle the claim as a condition to indemnification. No Settlement shall bind any party without such party's written consent. Failure to provide prompt notice shall not affect the indemnification provided hereunder except to the extent that a party has actually been prejudiced as a result of such failure.

**9. Termination of Agreement**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) This Agreement and the voting trust created hereby shall terminate with respect to all of the Subject Interests (i) at the option of the Purchaser with ten (10) business days prior written notice delivered by the Purchaser to the Trustee and Voting Consultant, upon July 1 or December 31 of any year, (ii) at the option of the Purchaser, upon the Purchaser beneficially owning less than 5% of the outstanding Shares, (iii) as provided with respect to certain transfers of Subject Interests in Section 3 above, or (iv) upon 10 business days written notice delivered by Purchaser to the Trustee and Voting Consultant following any failure to agree to the renewal or extension of the term for the Trustee or the Voting Consultant as provided in the Letter Agreement or Consulting Agreement, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon the termination of this Agreement with respect to the Subject Interests, the voting trust created pursuant to Section 1 hereof shall cease to have any effect with respect to the Subject Interests, and the parties hereto shall have no further rights or obligations under this Agreement with respect to the Subject Interests.

**(b) Name of Issuer:**
LibreMax Asset-Backed Income Fund

**(c) Address of Issuer's Principal Executive Offices:**
c/o U.S. Bank Global Fund Services, 615 East Michigan Street, Milwaukee, WI, 53202

Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

**Item 4. Purpose of Transaction**

Agreement and Plan of Exchange 

On April 30, 2026, pursuant to an Agreement and Plan of Exchange, the Issuer acquired substantially all of the assets of multiple affiliated private investment vehicles (the "Transferring Vehicles") in exchange (the "Exchange") for newly issued Class I Common Shares of the Issuer with an aggregate net asset value equal to the value of assets transferred (less liabilities assumed), based on valuations determined under the Issuer's procedures adopted pursuant to Rule 2a-5 of the Investment Company Act of 1940, as amended (the "Investment Company Act"), as of the agreed valuation time. Pursuant to the Agreement and Plan of Exchange, immediately prior to the Exchange, certain investors, including the Funds, contributed all of their direct interests in one of the Transferring Vehicles and the feeder funds for the Transferring Vehicles (the "Feeder Funds", and together with the Transferring Vehicles, the "Liquidating Entities"), as applicable, to LibreMax ABIF and in exchange received corresponding Interests in LibreMax ABIF. Immediately following the Exchange, such Class I Common Shares issued by the Issuer were promptly distributed in liquidating distributions pro rata to the partners of the Liquidating Entities, in exchange for the applicable partners' interests in the Liquidating Entities, and LibreMax ABIF became the ultimate holder of such Class I Common Shares.

Contribution and Distribution Agreement

On April 30, 2026, the Funds and ICONIQ Capital, on behalf of the Funds as investors in (i) LibreMax Structured Opportunities Partners I, LP, (ii) LibreMax Structured Opportunities Offshore Partners I, LP, (iii) LibreMax Structured Opportunities Partners II, LP, and (iv) LibreMax Structured Opportunities Offshore Partners II, LP, each of which is a Feeder Fund that invests in Transferring Vehicles party to the Agreement and Plan of Exchange, entered into a Contribution and Distribution Agreement (the "Contribution Agreement") with LibreMax ABIF, LibreMax GP, LLC, the general partner of LibreMax ABIF (the "GP"), and the other parties thereto, pursuant to which ICONIQ Capital agreed on behalf of the Funds to contribute, assign, transfer and deliver to LibreMax ABIF all of the Funds' respective right, title and interest in the Feeder Funds (the "Contributed Interests") in exchange for Interests in LibreMax ABIF based on the net asset value of, and corresponding to, the Contributed Interests as of 11:59 p.m. (New York City time) on April 30, 2026. 

The foregoing description of the Contribution Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Contribution Agreement, which is filed as Exhibit 99.2 and is incorporated herein by reference.

Following the Exchange, the Interests in LibreMax ABIF held by the Funds represented an indirect economic interest in the following amounts of Class I Common Shares of the Issuer: (a) for GPS 2024, 3,328,368.85 Class I Common Shares; (b) for GPS 2025, 4,713,824.78 Class I Common Shares; and (c) for GPS 2026, 6,066,474.36 Class I Common Shares.

Voting and Dispositive Rights Under the First Amended and Restated Limited Partnership Agreement of LibreMax ABIF Partners, LP.

Under the First Amended and Restated Limited Partnership Agreement of LibreMax ABIF Partners, LP, dated April 30, 2026, (the "LPA"), although the limited partners of LibreMax ABIF, including the Funds, shall take no part in the conduct or control of LibreMax ABIF and shall have no right or authority to act for or bind LibreMax ABIF or otherwise deal with third parties on behalf of LibreMax ABIF, it is the intention of LibreMax ABIF to operate as a pass-through entity with respect to the Class I Common Shares of the Issuer held by LibreMax ABIF such that the economic and voting experience of such limited partners is substantially equivalent to the experience such limited partners would have had they invested directly in the Issuer. Pursuant to the LPA, each limited partner, including the Funds, may, as of the last day of each quarter, upon at least 30 days' prior notice to the GP, irrevocably withdraw up to the entire balance of such limited partner's capital account, provided that LibreMax ABIF will not offer voluntary withdrawals outside of the periodic repurchase offer process of the Issuer. Under the LPA, whenever the Issuer conducts a repurchase offer for its Class I Common Shares pursuant to Rule 23c-3 under the Investment Company Act, LibreMax ABIF shall give effect to such repurchase offer with respect to the Interests by offering the limited partners, including the Funds, by written notice the right to have their indirect holdings of Class I Common Shares repurchased on the same terms as offered by the Issuer and LibreMax ABIF shall generally pay withdrawal proceeds to the limited partners within the time period specified in the Issuer's repurchase offer, without interest, which shall generally be within 30 days after the applicable withdrawal date. If the Issuer's repurchase offer is oversubscribed or otherwise results in a reduction of the amount repurchased, LibreMax ABIF shall allocate the corresponding distributions among the electing limited partners on a pro rata basis, reflecting LibreMax ABIF's pro rata participation in the Issuer's repurchase offer. 

The GP may suspend withdrawals by the limited partners under certain limited circumstances, and the GP may, in its sole discretion, modify or waive any or all of the withdrawal terms with respect to any limited partner without notice to or consent from other limited partners. Other than pursuant to the withdrawal rights specified above, the limited partners, including the Funds, may not transfer or sell all or any portion of their Interests without the prior written consent of the GP, which consent can be withheld in the GP's sole discretion, provided that such consent to any transfer or transfers of Interests to another limited partner shall not be withheld except under limited circumstances. 

Pursuant to the LPA, whenever LibreMax ABIF, in its capacity as a holder of Class I Common Shares of the Issuer, is requested or required to vote on any matter relating to the Issuer, including but not limited to the election of trustees of the Issuer, the approval of any investment advisory agreement of the Issuer, or any other matter requiring a vote of the Issuer's shareholders, the GP shall pass through such voting rights to the limited partners on a look-through basis by promptly providing each limited partner, including the Funds, with written notice of any such vote, together with all proxy materials or other information provided to LibreMax ABIF by the Issuer. Each limited partner shall then be entitled to instruct the GP as to how to vote the portion of LibreMax ABIF's interest in the Issuer that is attributable to such limited partner's Interests, based on such limited partner's participation percentage in the Issuer, and the GP shall vote LibreMax ABIF's interest in the Issuer in accordance with the instructions received by the limited partners. With respect to any portion of LibreMax ABIF's interest in the Issuer for which the GP does not receive timely voting instructions from a limited partner, the GP shall vote such portion in the same proportion as the instructions received from limited partners who did provide timely instructions. Under the LPA, to the extent any limited partner has irrevocably transferred and assigned its voting rights to an independent trustee who has no affiliation with such limited partner, the GP shall vote the interests of such limited partner in accordance with the instructions of such trustee.

Lock-Up Letter

On April 30, 2026, the Funds and ICONIQ Capital entered into a letter agreement (the "Lock-Up Letter") with LibreMax Capital, LLC, the investment manager of the Issuer and LibreMax ABIF (the "Investment Manager"), pursuant to which ICONIQ Capital on behalf of the Funds agreed that for a period of six months following the date on which the Funds acquire the Interests in LibreMax ABIF, ICONIQ Capital will not exercise any withdrawal rights under the LPA on behalf of the Funds and shall not exercise any right on behalf of the Funds to have their indirect holdings of Class I Common Shares repurchased on the same terms as offered by the Fund in any repurchase offer.

The foregoing description of the Lock-Up Letter does not purport to be complete and is qualified in its entirety by reference to the full text of the Lock-Up Letter, which is filed as Exhibit 99.3 and is incorporated herein by reference.

Voting Trust Agreement

As of April 2, 2026, ICONIQ Capital, as the beneficial owner of the Interests of LibreMax ABIF held directly by the Funds, entered into an Amended and Restated Voting Trust Agreement (the "Voting Trust Agreement") with CSC Delaware Trust Company (the "Trustee") and Glass, Lewis & Co., LLC (the "Voting Consultant").  Pursuant to the Voting Trust Agreement, (i) ICONIQ Capital irrevocably transferred and assigned to the Trustee its right to instruct the GP on how to vote or consent in connection with all of its voting and consent rights and responsibilities as a beneficial owner of the Interests held directly by the Funds and any additional Interests of which ICONIQ Capital becomes the beneficial owner during the term of the Voting Trust Agreement (such Interests, when beneficially owned by ICONIQ Capital, the "Subject Interests") with respect to any matters that holders of Class I Common Shares of the Issuer are entitled to vote on that would cause the Class I Common Shares to constitute "voting securities" under the Investment Company Act, including but not limited to the election of trustees to the Board of Trustees of the Issuer (the "Voting Matters") and (ii) the Voting Consultant agreed to analyze the Voting Matters requiring the beneficial owner of the Subject Interests to instruct the GP on how to vote or consent and provide a recommendation to the Trustee of how to instruct the GP to vote or consent with respect to such Voting Matters.  The Trustee is obligated to act in accordance with the voting or consent recommendation made by the Voting Consultant and will not provide a voting instruction to the GP on behalf of ICONIQ Capital if the Voting Consultant fails to provide a voting or consent recommendation to the Trustee on or prior to the deadline for submission of such vote or consent.

Pursuant to the Voting Trust Agreement, ICONIQ Capital retained the right to sell or otherwise transfer the Subject Interests at any time in its sole discretion, subject to the transfer restrictions contained in the LPA, any contractual restrictions and under applicable law. Upon the transfer by ICONIQ Capital of any Subject Interests to an unaffiliated third-party, such Subject Interests shall no longer be subject to the Voting Trust Agreement.  The Voting Trust Agreement may be terminated (i) at the option of ICONIQ Capital with 10 business days prior written notice to the Trustee and Voting Consultant, upon July 1 or December 31 of any year, (ii) at the option of ICONIQ Capital, upon ICONIQ Capital beneficially owning less than 5% of the outstanding Class I Common Shares of the Issuer, (iii) in connection with certain transfers of the Subject Interests or (iv) upon 10 business days written notice delivered by ICONIQ Capital to the Trustee and Voting Consultant following the failure to agree to the renewal or extension of the term for the Trustee or Voting Consultant.

The foregoing description of the Voting Trust Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Voting Trust Agreement, which is filed as Exhibit 99.4 and is incorporated herein by reference.

In addition, on April 30, 2026, the Funds and ICONIQ Capital on behalf of the Funds entered into a Strategic Relationship Agreement (the "Strategic Agreement") with the Investment Manager. Pursuant to the Strategic Agreement, and in consideration for the Funds' exchange of interests in the Feeder Funds for the Interests in LibreMax ABIF, the Investment Manager agreed to pay the Funds a share of the Investment Manager's net profits attributable to the Issuer (the "Profit Share"), subject to certain conditions, including maintaining compliance with the Lock-Up Letter disclosed above. The Investment Manager in the Strategic Agreement further agreed to offer ICONIQ Capital and its affiliates pro rata co-investment opportunities with the Issuer on terms no less favorable than those offered to other co-investors, subject to legal and regulatory constraints, and grants ICONIQ Capital certain notice, consent, and information rights with respect to the Investment Manager's ownership, governance, and transactions that could dilute or impair the Profit Share.

The Reporting Persons continuously assess the Issuer's business, financial condition, results of operations and prospects, general economic conditions, other developments and additional investment opportunities. Depending on such assessments, and any applicable transfer restrictions, the Reporting Persons and/or their affiliates may acquire additional securities of the Issuer or may determine to sell or redeem or otherwise dispose of all or some of the Interests that represent an indirect interest in the Issuer's securities. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices, the financial condition, results of operations and prospects of the Issuer, alternative investment opportunities, general economic, financial market and industry conditions and other factors that the Reporting Persons and/or their affiliates may deem material to their investment decision.

Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the Class I Common Shares, conditions in the securities markets and general economic and industry conditions, and any contractual or legal restrictions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management of the Issuer and/or the Issuer's Board of Trustees (the "Board"), engaging in discussions with other shareholders of the Issuer and others about the Issuer and the Reporting Persons' investment, making proposals to the Issuer concerning changes to the capitalization, Board composition or operations of the Issuer or changing their intention with respect to any and all matters referred to in subparagraphs (a) through (j) of Item 4 of Schedule 13D.
