PROXY STATEMENT

ANNUAL MEETING OF SHAREHOLDERS

May 29, 2024

This Proxy Statement is furnished in connection with the solicitation of proxies on behalf of the Board of Trustees (the "Board" and each member thereof, a "Trustee" and collectively, the "Trustees") of AG Twin Brook Capital Income Fund, a Delaware statutory trust (the "Company," "we," "us," or "our"), for use at the Company's 2024 Annual Meeting of Shareholders (the "Annual Meeting") to be held on Wednesday, May 29, 2024, at 9:00 a.m. Central Time, or at any and all adjournments or postponements thereof, for the purposes set forth in the accompanying Notice of 2024 Annual Meeting of Shareholders dated April 18, 2024. The Company is a closed-end management investment company that has elected to be treated as a business development company ("BDC") under the Investment Company Act of 1940, as amended (the "1940 Act"). AGTB Fund Manager, LLC, a Delaware limited liability company (the "Adviser"), serves as the investment adviser of the Company and also serves as the Administrator of the Company (in such capacity, the “Administrator”). The principal executive offices of each of the Company, the Adviser, and the Administrator are located at 245 Park Avenue, 26th Floor, New York, NY 10167.

You can attend the Annual Meeting in person on the 36th floor of the Adviser’s offices located at 111 South Wacker Drive, Chicago, Illinois 60606. If you want to attend the Annual Meeting, you must pre-register by emailing TCAP@angelogordon.com not later than 5:00 p.m., Eastern Time on Tuesday, May 28, 2024. For security reasons, you will be required to show a form of government-issued photo identification (e.g., a driver’s license or a passport) when you arrive at the Annual Meeting. If you need special assistance at the Annual Meeting because of a disability, please contact TCAP@angelogordon.com. You will need to provide evidence that you are a shareholder as of the close of business of the Record Date. This can be a copy of your proxy card or a brokerage statement showing your shares as of the close of business on the Record Date. If you hold your shares in “street name” through a broker, bank or other nominee, you will need to contact the broker, bank or other nominee that holds your shares in order to obtain a legal proxy from that broker, bank or other nominee. Please note that if you do not provide a copy of such legal proxy at the Annual Meeting, you may still attend the Annual Meeting as long as you have registered, but you will not be able to vote shares in person at the Annual Meeting.

This Proxy Statement and the accompanying Notice and form of proxy are being provided to shareholders on or about April 18, 2024. The Board has fixed the close of business on March 29, 2024 as the record date (the "Record Date") for the determination of shareholders entitled to receive notice of, and to vote at, the Annual Meeting. As of the Record Date, 41,286,216 common shares of beneficial interest, par value $0.001 per share (the "Common Shares"), of the Company were issued and outstanding. Shareholders of the Company are entitled to cast one vote for each share held.

If the form of proxy is properly executed and returned in time to be voted at the Annual Meeting, the shares covered thereby will be voted at the Annual Meeting in accordance with the instructions marked thereon. All properly executed proxies received by the Board that do not specify how shares should be voted will be voted "FOR" the election of the Class II Trustee nominees listed herein ("Proposal 1"); and “FOR” the ratification of the selection of Deloitte & Touche LLP (“Deloitte & Touche”) as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2024 (“Proposal 2”), and in the discretion of the persons named as proxies in connection with any other matter which may properly come before the Annual Meeting or at any adjournment or postponement thereof.

The Board does not know of any matter to be considered at the Annual Meeting other than the election of the Class II Trustee nominees and the ratification of the selection of the Company’s independent registered public accounting firm. Should any other matter requiring a vote of shareholders arise, it is the intention of the persons named in the

4

proxy to vote in accordance with their discretion on such matters. Shareholders have no dissenters’ or appraisal rights in connection with any of the proposals described herein.

In addition to mail and e-mail, proxies may be solicited personally, via the Internet or by telephone, by regular employees of the Administrator and its affiliates. No additional compensation will be paid to such regular employees for such services.

The Company will pay the costs and expenses associated with this Proxy Statement and solicitation, including expenses incurred in connection with the printing and mailing of this Proxy Statement and its enclosures.

VOTING INFORMATION

Record Date and Who May Vote

The Board selected March 29, 2024 as the Record Date. This means that if you were a registered shareholder with our transfer agent and registrar, SS&C Technologies, Inc. (“SS&C”), as of the close of business on the Record Date, you may vote your shares on the matters to be considered by our shareholders at the Annual Meeting. If your shares were held in "street name" on that date, the broker or other nominee that was the record holder of your shares has the authority to vote them at the Annual Meeting in accordance with your instructions. They have forwarded to you this Proxy Statement seeking your instructions on how you want your shares voted. Please note that to be sure your vote is counted on the Company’s proposal to elect trustees, you should instruct your broker, bank, trustee or nominee how to vote your shares by following the voting instructions provided by your broker, bank, trustee or nominee. If you do not provide voting instructions, votes may not be cast on your behalf with respect to such proposal.

How to Vote

If you are a holder of record of Common Shares on the Record Date, you may have your shares voted on matters presented at the Annual Meeting in person or by giving us your proxy over the Internet as described in your notice regarding the Internet availability of proxy materials (the “Notice”). You do not need to attend the Annual Meeting in order to vote your shares.

Alternatively if you have received a paper copy of the proxy card, shareholders can follow the instructions on such proxy card and authorize a proxy via the Internet or mail to vote in accordance with the instructions provided below. Authorizing a proxy through the Internet requires you to input the control number located on the Notice or proxy card. After inputting the control number, you will be prompted to direct your proxy to vote on the proposals. You will have an opportunity to review and make any necessary changes to your directions before you submit your directions via the Internet link. If you are the beneficial owner of your shares, you will need to follow the instructions provided by your broker, bank, trustee or nominee regarding how to instruct your broker, bank, trustee or nominee to vote your shares at the Annual Meeting.

•By Internet: www.voteproxy.com

•By mail: You may vote by proxy by following the directions and indicating your instructions on the enclosed proxy card, dating and signing the proxy card, and promptly returning the proxy card in the envelope provided, which requires no postage if mailed in the United States. Please allow sufficient time for your proxy card to be received on or prior to 11:59 p.m., Central Time, on May 28, 2024.

You may receive more than one proxy statement and proxy card if your shares are held through more than one account (e.g., through different brokers or nominees). Each proxy card only covers those Common Shares held in the applicable account. If you hold shares in more than one account, you will have to provide voting instructions as to all your accounts to vote all your shares.

How to Revoke or Change Your Vote

If you are a shareholder of record of the Company, you can change your vote or revoke your proxy by: (i) delivering a written revocation notice before 11:59 p.m. Central Time on May 28, 2024 to the Company’s corporate secretary, Jenny B. Neslin, at AG Twin Brook Capital Income Fund, 245 Park Avenue, 26th Floor, New York, New York 10167; Attention: Secretary; (ii) voting again using the Internet before 11:59 p.m. Central Time on May 28, 2024 (your latest Internet proxy is the one that will be counted); or (iii) attending and voting during the Annual Meeting. Simply attending the Annual Meeting will not, by itself, revoke your proxy. The Company encourages Shareholders who wish to change their vote to do so by voting again using the Internet. If you hold shares of the Company through a broker, bank, trustee or nominee, you must follow the instructions you receive from your nominee in order to revoke your voting instructions.

Quorum Required

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, in person or by proxy, of the holders of at least one-third of the outstanding Common Shares shall constitute a quorum for the Annual Meeting. There were 41,286,216 Common Shares outstanding on the Record Date, of which at least 13,762,072 must be present in person or represented by proxy at the Annual Meeting for a quorum to be present. Each Common Share is entitled to one vote. Abstentions will be treated as shares present for quorum purposes. Shares for which brokers have not received voting instructions from the beneficial owner of the shares and do not have discretionary authority to vote the shares on certain proposals (which are considered "Broker Non-Votes" with respect to such proposals) will be treated as shares present for quorum purposes. However, abstentions and Broker Non-Votes are not counted as votes cast. Cumulative voting is not permitted.

If you attend the Annual Meeting or vote your shares using the enclosed proxy card or voting instruction form (including any Internet voting procedures provided), your shares will be counted toward a quorum, even if you abstain from voting on a particular matter.

If a quorum is not present at the Annual Meeting, the Annual Meeting may be adjourned in accordance with the Company's bylaws. To achieve the requisite quorum for a meeting that has been adjourned, additional solicitations may be sought pursuant to the terms of the bylaws.

Broker Non-Votes

If you are the beneficial owner of shares held through a broker or other nominee and do not vote your shares or provide voting instructions, your broker may vote for you on routine proposals but not on non-routine proposals. Only Proposal 2 - To ratify the selection of Deloitte & Touche as our independent registered public accounting firm for the fiscal year ending December 31, 2024 - would be evaluated as "routine." If you do not vote on the non-routine proposals or provide voting instructions, your broker will not be allowed to vote your shares - this will result in a Broker Non-Vote.

Vote Required and How Votes are Counted

Election of Trustees. The Trustees shall be elected by an affirmative vote of the holders of a plurality of the votes cast by shareholders by proxy at the Annual Meeting. Abstentions will not be included in determining the number of votes cast and, as a result, will have no effect on this proposal. Common Shares represented by Broker Non-Votes are not considered votes cast and thus have no effect on this proposal.

Ratification ofIndependentRegisteredPublicAccountingFirm. The affirmative vote of the holders of a majority of the votes cast by shareholders by proxy is required to ratify the appointment of Deloitte & Touche to serve as the Company’s independent registered public accounting firm. Abstentions will not be included in determining the number of votes cast and, as a result, will have no effect on this proposal. Because brokers will have discretionary

6

authority to vote for the ratification of the selection of the Company’s independent registered public accounting firm in the event that they do not receive voting instructions from the beneficial owner of the shares, your broker will be permitted to vote your shares for this proposal.

Additional Solicitation. If there are not enough votes to approve any proposals at the Annual Meeting, the Chairman of the Annual Meeting may adjourn the Annual Meeting to permit the further solicitation of proxies.

Also, a shareholder vote may be taken on one or more of the proposals in this Proxy Statement prior to any such adjournment if a quorum is present and there are sufficient votes for approval of such proposal(s).

If you have any questions regarding the proxy materials, please contact the Secretary of the Company as set forth herein. If a shareholder of record has properly submitted a proxy that is received prior to the Annual Meeting and has not been revoked, the shares represented thereby will be voted in accordance with the instructions provided or, if no instructions are provided, the proxy will be voted "FOR" the proposals described in this Proxy Statement and in the discretion of the persons named as proxies in connection with any other matter that may properly come before the Annual Meeting or any adjournment(s) or postponement(s) thereof.

If (i) you are a member of a household in which multiple shareholders of the Company share the same address, (ii) your shares are held in "street name" and (iii) your broker or bank has received consent (or deemed consent) to household material, then your broker or bank may send to your household only one copy of this Proxy Statement and our annual report on Form 10-K for the year ended December 31, 2023 (the "2023 Annual Report"), unless your broker or bank has received contrary instructions from a shareholder in your household. If you are part of a household that has received only one copy of this Proxy Statement and the 2023 Annual Report, the Company will deliver promptly to you, upon written or oral request, a separate copy of this Proxy Statement and the 2023 Annual Report at the shared address to which a single copy of the documents was delivered. To receive a separate copy of this Proxy Statement or the 2023 Annual Report, please send your request to AG Twin Brook Capital Income Fund, 245 Park Avenue, 26th Floor, New York, NY 10167, Attention: Secretary, (212) 692-2000. If your shares are held with certain banks, trust companies, brokers, dealers, investment advisers and other financial intermediaries (each, an "Authorized Institution") and you would like to receive a separate copy of future proxy statements, notices of internet availability of proxy materials, prospectuses or annual reports or you are now receiving multiple copies of these documents and would like to receive a single copy in the future, please contact your Authorized Institution.

PROPOSAL 1

ELECTION OF CLASS II TRUSTEES

Pursuant to the Company’s declaration of trust and bylaws, the Board of Trustees may modify the number of members of the Board of Trustees provided that the number thereof shall never be less than three. In accordance with the Company’s declaration of trust, the Board is currently composed of four Trustees, who are divided into three classes with staggered terms of three years, such that the term of office of one class expires at each annual meeting of shareholders. The terms of the Company’s Class II Trustees expire at the Annual Meeting. As such, the holders of the Company's Common Shares are being asked to elect Trevor Clark and James Hallene as Class II Trustees of the Company (the “Class II Trustee Nominees”), each to serve for a three-year term expiring at the Company’s 2027 annual meeting of shareholders or until his successor is duly elected and qualified. Messrs. Clark and Hallene are currently serving as Class II Trustees of the Company and have consented to being named in this Proxy Statement and agreed to continue to serve as Class II Trustees, if elected. If either of Messrs. Clark or Hallene is not available to serve as a Trustee, proxies may be voted for the election of other persons selected by the Board. It is not anticipated that Messrs. Clark or Hallene will be unable or unwilling to serve. Shareholders of the Company have no cumulative voting rights with respect to the election of Trustees.

Information about the Class II Trustee Nominees and Trustees

The following tables provide information concerning the Class II Trustee Nominees and the other individuals serving as Trustees of the Company, as of the date of this Proxy Statement. The Class II Trustee Nominees are listed first in the table under "Class II Trustee Nominees." The terms of the Class III and Class I Trustees expire in 2025 and 2026, respectively.

The Board believes that each of the Trustees, including the Class II Trustee Nominees, has the experience, qualifications, attributes and skills appropriate to serve as a Trustee of the Company, in light of the Company's business and structure. The significance or relevance of a nominee's or Trustee’s particular experience, qualifications, attributes and/or skills is considered by the Board on an individual basis. Experience, qualifications, attributes and/or skills common to all nominees and Trustees include the ability to critically review, evaluate and discuss information provided to them and to interact effectively with the other Trustees and with representatives of the Adviser and its affiliates, other service providers, legal counsel and the Company’s independent registered public accounting firm, the capacity to address financial and legal issues and exercise reasonable business judgment, and a commitment to the representation of the interests of the Company and the shareholders. The Company’s nominating and corporate governance committee’s (the “Nominating and Corporate Governance Committee”) charter contains certain other factors that are considered by the Nominating and Corporate Governance Committee in identifying and evaluating potential nominees to serve as Trustees.

Based on each nominee's experience, qualifications, attributes and/or skills, considered individually and with respect to the experience, qualifications, attributes and/or skills of the other Trustees, the Board has concluded that each nominee should continue to serve as a Trustee. Additionally, below is a brief discussion of the experience, qualifications, attributes and/or skills of the Class II Trustee Nominees and the continuing Trustees that led the Board, in consultation with the Nominating and Corporate Governance Committee, to conclude that such individual should serve as a Trustee. There are no family relationships among any Trustees, Trustee nominees and executive officers of the Company.

CORPORATE GOVERNANCE

Role of the Board of Trustees, Leadership Structure and Risk Oversight

The Role of the Board

Our business and affairs are managed under the oversight of the Board. The Board consists of four members, three of whom are Independent Trustees (defined below). The Board elects our officers, who serve at the discretion of the Board. The responsibilities of the Board include oversight of fair value determinations of our assets, corporate governance activities, oversight of our financing arrangements and oversight of our investment activities. The Board’s role is one of oversight, rather than active management. Oversight of the Company’s investment activities extends to oversight of the risk management processes employed by the Adviser as part of its day-to-day management of the Company’s investment activities. The goal of the Board’s risk oversight function is to ensure that the risks associated with the Company’s investment activities are accurately identified, thoroughly investigated, and responsibly addressed.

Board Oversight of Risk Management

The Board performs its risk oversight function primarily through (i) its standing committees, which report to the entire Board and are comprised solely of Independent Trustees, and (ii) active monitoring of the Company’s Chief Compliance Officer and our compliance policies and procedures. Oversight of other risks is delegated to the committees.

Oversight of the Company’s investment activities extends to oversight of the risk management processes employed by the Adviser as part of its day-to-day management of the Company’s investment activities. The Board anticipates reviewing risk management processes at both regular and special board meetings throughout the year, consulting with appropriate representatives of the Adviser as necessary and periodically requesting the production of risk management reports or presentations, including on valuation risk, counterparty risk, compliance risk, and cybersecurity risk. The Board receives a wide range of reports on the Company’s activities from the Adviser and other service providers, including reports regarding the Company’s investment portfolio, the compliance of the Company with applicable laws, and the Company’s financial accounting and reporting. The Board’s Audit Committee also meets regularly with the Chief Financial Officer and the Company’s independent registered public accounting firm to discuss, among other things, the internal control structure of the Company’s financial reporting function. The Board also meets periodically with the investment professionals of TPG Angelo Gordon to receive reports regarding the management of the Company and the Company’s portfolio, including its investment risks. In addition, at its quarterly meetings, the Audit Committee meets with the independent valuation firm that evaluates certain of the Company’s securities holdings for which there are not readily available market values. The goal of the Board’s risk oversight function is to ensure that the risks associated with our investment activities are accurately identified, thoroughly investigated and responsibly addressed.

The Board recognizes that not all risks that may affect the Company can be identified, that it may not be practical or cost-effective to eliminate or mitigate certain risks, that it may be necessary to bear certain risks (such as investment-related risks) to achieve the Company’s goals, that reports received by the Trustees with respect to risk management matters are typically summaries of the relevant information, and that the processes, procedures and controls employed to address risks may be limited in their effectiveness. As a result of the foregoing and other factors, risk management oversight by the Board and by the committees is subject to substantial limitations.

Board Structure and Leadership

The Board has structured itself in a manner that it believes allows it to perform its oversight function effectively. The Board consists of four Trustees, three of whom are not “interested persons,” as defined in the 1940 Act, and are Independent Trustees, in accordance with the standards set forth in Section 2(a)(19). Section 2(a)(19) of the 1940 Act defines an “interested person” to include, among other things, any person who has, or within the last two years had, a material business or professional relationship with the Company or the Adviser. We refer to individuals who

14

are not “interested persons” in accordance with Section 2(a)(19) as our Independent Trustees (the “Independent Trustees”). In determining independence, the Board reviews and considers such information as it deems appropriate including, among other items, completed Trustee due diligence questionnaires, and may conduct interviews and background checks as appropriate. The member of the Board who is not an Independent Trustee, Mr. Clark, is referred to as Interested Trustee (the “Interested Trustee”).

Our Board has established an Audit Committee and a Nominating and Corporate Governance Committee, and may establish additional committees from time to time as necessary. The Audit Committee and Nominating and Corporate Governance Committee are comprised solely of Independent Trustees. The scope of the responsibilities assigned to each of these committees is discussed in greater detail below. Trevor Clark, an "interested person" of TPG Angelo Gordon, serves as Chairman of our Board. We believe that Mr. Clark’s history with TPG Angelo Gordon, his familiarity with its investment platform, and his extensive knowledge of and experience in the financial services industry, specifically within middle market direct lending, qualify him to serve as the Chairman of our Board.

Our Board does not have a lead Independent Trustee. We are aware of the potential conflicts that may arise when a non-Independent Trustee is Chairman of our Board, but believe these potential conflicts are offset by our strong corporate governance practices. Our corporate governance practices include regular meetings of the Independent Trustees in executive session without the presence of Interested Trustees and management, and the establishment of an Audit Committee and a Nominating and Corporate Governance Committee, each of which is comprised solely of Independent Trustees. In addition, although the Independent Trustees recognize that having a lead Independent Trustee may in some circumstances help coordinate communications with management, and otherwise assist a board in the exercise of its oversight duties, the Independent Trustees believe that, because of the relatively small size of the Board, the ratio of Independent Trustees to Interested Trustees, and the good working relationship among the Board members, it has not been necessary to designate a lead Independent Trustee.

The Board periodically reviews its leadership structure, including the role of the Chairman of the Board. The Board also conducts an annual self-assessment during which it reviews its leadership and committee structure and considers whether its structure remains appropriate in light of the Company’s current operations. The Board believes that its leadership structure, including the current percentage of the Board members who are Independent Trustees, is appropriate given its specific characteristics. These characteristics include (i) the extent to which the work of the Board is conducted through the standing committees, each of whose meetings are chaired by an Independent Trustee; (ii) the extent to which the Independent Trustees meet as needed in the absence of members of management and members of the Board who are “interested persons” of the Company; and (iii) Mr. Clark’s positions with the Adviser and TPG Angelo Gordon, which enhance the Board’s understanding of the operations of the Adviser and TPG Angelo Gordon. The Board evaluates its performance on an annual basis.

On November 1, 2023, in anticipation of the TPG Transaction (as defined below in “Certain Relationships and Related Party Transactions”), and in order to ensure that the TPG Transaction complied with Section 15(f) of the 1940 Act, including the requirement that at least 75% of the members of the Board not be “interested persons” (as defined in the 1940 Act) of the Company for three years following the consummation of the TPG Transaction, Terrence Walters resigned from his position as a Trustee on the Company’s Board effective upon the consummation of the TPG Transaction. Mr. Walters continues to serve in his roles as the Company’s Chief Financial Officer and Treasurer. In addition, the Board determined to decrease the size of the Board from five members to four members to address the vacancy left by Mr. Walters’ resignation.

Board Meetings and Board/Committee Attendance

We require each Trustee to make a diligent effort to attend all Board and committee meetings as well as each annual meeting of our shareholders. During 2023, including both regularly scheduled and special meetings, our Board met a total of seven times, the Audit Committee met a total of four times, and the Nominating and Corporate Governance Committee met a total of four times. During 2023, all of the Company’s Trustees attended at least 75% of the meetings of the Board. Additionally, in 2023, 100% of the members of the Audit Committee attended all of the

15

regularly scheduled meetings of such committee, and 100% of the members of the Nominating and Corporate Governance Committee attended all of the regularly scheduled meetings of such committee. During each meeting of the Audit Committee, the Audit Committee met privately with the Company's independent registered public accounting firm. All of the Trustees attended the Company’s 2023 annual meeting of shareholders held in May 2023.

Committees of the Board

The Board has established an Audit Committee and a Nominating and Corporate Governance Committee and may establish additional committees in the future.

Audit Committee

The Audit Committee operates pursuant to a charter approved by the Board, which sets forth the responsibilities of the Audit Committee and is available on the Company’s website, www.AGTBCAP.com, under the heading “Resources”. The Audit Committee's responsibilities include selecting our independent registered public accounting firm, reviewing with such independent registered public accounting firm the planning, scope and results of their audit of our financial statements, pre-approving the fees for services performed, reviewing with the independent registered public accounting firm the adequacy of internal control systems, reviewing our annual financial statements, overseeing internal audit staff and periodic filings, receiving our audit reports and reviewing financial statements, and, with the assistance of an independent valuation firm, aiding the Board in fair value pricing debt and equity securities that are not publicly traded or for which current market values are not readily available. Management is responsible for the preparation, presentation, and integrity of our financial statements, our accounting and financial and reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations.

The Audit Committee is currently composed of Messrs. Bowers, Hallene and Ludwick, all of whom are not considered "interested persons" of the company as that term is defined in Section 2(a)(19) of the 1940 Act. Mr. Ludwick serves as Chairman of the Audit Committee. The Board has determined that Mr. Ludwick is an "audit committee financial expert" as that term is defined under Item 407 of Regulation S-K, as promulgated under the Exchange Act. Messrs. Bowers, Hallene and Ludwick meet the current independence and experience requirements of Rule 10A-3 under the Exchange Act.

Nominating and Corporate Governance Committee

The Board has also established a Nominating and Corporate Governance Committee that acts pursuant to a written charter, which is available on the Company’s website, www.AGTBCAP.com, under the heading “Resources”. The members of the Nominating and Corporate Governance Committee are our Independent Trustees. Mr. Bowers serves as Chairman of the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee is responsible for selecting, researching and nominating trustees for election by our shareholders, selecting nominees to fill vacancies on the Board or a committee of the Board, developing and recommending to the Board a set of corporate governance principles and overseeing the evaluation of the Board and our management.

The Nominating and Corporate Governance Committee seeks candidates who possess the background, skills and expertise to make a significant contribution to the Board, our Company and our shareholders. In considering possible candidates for election as a trustee, the Nominating and Corporate Governance Committee takes into account, in addition to such other factors as it deems relevant, the desirability of selecting trustees who:

• are of high character and integrity;

• are accomplished in their respective fields, with superior credentials and recognition;

• have relevant expertise and experience upon which to be able to offer advice and guidance to management;

16

• have sufficient time available to devote to our affairs;

• are able to work with the other members of the Board and contribute to our success;

• can represent the long-term interests of our shareholders as a whole; and

• are selected such that the Board represents a range of backgrounds and experience.

The Nominating and Corporate Governance Committee also evaluates candidates proposed by shareholders using the factors described above. The Nominating and Corporate Governance Committee has not adopted a formal policy with regard to the consideration of diversity in identifying trustee nominees. In determining whether to recommend a trustee nominee, the Nominating and Corporate Governance Committee considers and discusses diversity, among other factors, with a view toward the needs of the Board as a whole. The Nominating and Corporate Governance Committee generally conceptualizes diversity expansively to include, without limitation, concepts such as race, gender, ethnic background, national origin, differences of viewpoint, professional experience, education, skill and other qualities that contribute to the Board, when identifying and recommending trustee nominees. The Nominating and Corporate Governance Committee believes that the inclusion of diversity as one of many factors considered in selecting trustee nominees is consistent with the goal of creating a board of trustees that best serves our needs and the interests of our shareholders.

Compensation of Executive Officers and Trustees

Compensation of Executive Officers

We do not currently have any employees. None of our executive officers receives direct compensation from us. We do not have a compensation committee because our executive officers are not compensated by the Fund. We do not engage any compensation consultants. The compensation of investment professionals of the Adviser is paid by the Adviser. We have agreed to reimburse the Administrator for our allocable portion of the compensation paid to, or compensatory distributions received by, our Chief Financial Officer, Chief Compliance Officer, and General Counsel, and any of their respective staff who provide services to us, operations and investor relations staff who provide services to us, and any internal audit staff, to the extent internal audit performs a role in our Sarbanes-Oxley Act of 2002 internal control assessment. Compensation paid to the Chief Compliance Officer is also approved by the Board of Trustees, including a majority of the Independent Trustees, in accordance with Rule 38a-1 under the 1940 Act.

In addition, to the extent that the Administrator outsources any of its functions, we will pay the fees associated with such functions at cost. We will agree to reimburse the Administrator for our allocable portion of the compensation of any personnel that it provides for our use.

Compensation of Trustees

Each Independent Trustee is entitled to receive an annual fee of $60,000, payable quarterly in cash on a prorated basis. The Company began paying its Independent Trustees’ annual fee in connection with the consummation of the merger with AGTB Private BDC (as described below in “Certain Relationships and Related Party Transactions”) on January 1, 2023. The Independent Trustees also receive reimbursement of reasonable out-of-pocket expenses incurred in connection with attending each regular Board meeting, each special meeting, and each committee meeting. No compensation is paid to trustees who are “interested persons,” as such term is defined in Section 2(a)(19) of the 1940 Act, of the Company.

Code of Ethics

The Company and the Adviser have adopted a compliance manual, including a code of ethics (the “Code of Ethics”) pursuant to Rule 17j-1 under the 1940 Act and Rule 204A-1 under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), respectively, and insider trading policy (the “Insider Trading Policy”), each of which establish procedures for personal investments and restricts certain personal securities transactions. The Insider Trading Policy does not expressly prohibit trustees, executive officers or employees of the Company and its affiliates from engaging in hedging transactions with respect to its securities. The Code of Ethics and Insider Trading Policy are applicable to the Company’s executive officers and Trustees, as well as all employees of our Adviser who provide services to the Company. The Company hereby undertakes to provide a copy of the Code of Ethics to any person, without charge, upon request. Requests for a copy of the Code of Ethics may be made in writing addressed to the Secretary of the Company, Jenny B. Neslin, AG Twin Brook Capital Income Fund, 245 Park Avenue, 26th Floor, New York, NY  10167. We intend to disclose any amendments to or waivers of required provisions of the Code of Ethics on Form 8-K or on the Company’s website, www.AGTBCAP.com.

Certain Relationships and Related Party Transactions

Investment Management Agreement; Administration Agreement

On November 1, 2023, the Company entered into an amended and restated investment management agreement (the “Investment Management Agreement”) with the Adviser, in connection with the closing of the previously announced transaction (the "TPG Transaction") pursuant to which TPG Inc. (NASDAQ: TPG) acquired Angelo Gordon (“TPG Angelo Gordon”), and TPG Angelo Gordon, including the Adviser, became indirect subsidiaries of TPG. Under applicable law, the TPG Transaction resulted in an assignment and automatic termination of the amended and restated investment management agreement, dated September 6, 2023 (the “Prior Investment Management Agreement”). The Investment Management Agreement became effective upon closing of the TPG Transaction and the terms of the Investment Management Agreement are identical to the Prior Investment Management Agreement. The Company’s shareholders approved the Investment Management Agreement at a special meeting of the shareholders of the Company held on September 26, 2023.

Pursuant to the Investment Management Agreement, the Company pays the Adviser a base management fee payable monthly in arrears at an annual rate of 1.25% of the value of the Company’s net assets as of the beginning of the first business day of the applicable month. For purposes of the Investment Management Agreement, net assets means the Company’s total assets less liabilities determined on a consolidated basis in accordance with GAAP. For the year ended December 31, 2023, the Company accrued approximately $7.7 million of base management fees payable to the Adviser. For the period from January 27, 2022 (Inception) to December 31, 2022, the Company accrued approximately $2.3 million of base management fees payable to the Adviser.

The Company also pays the Adviser a two-part incentive fee based on (i) the amount by which our pre-incentive fee net investment income returns exceed a certain “hurdle rate” and (ii) our capital gains. The Company will accrue, but will not pay, a capital gains incentive fee with respect to unrealized appreciation because a capital gains incentive fee would be owed to the Adviser if the Company were to sell the relevant investment and realize a capital gain. For the year ended December 31, 2023, the Company accrued approximately $8.6 million of income incentive fees. For the period from January 27, 2022 (Inception) to December 31, 2022, the Company accrued approximately $2.1 million of income incentive fees. As of December 31, 2023, the Company had approximately $496,000 of accrued capital gains incentive fees, of which none were paid or payable to the Adviser. As of December 31, 2022, the Company had approximately $249,000 of accrued capital gains incentive fees, of which none were paid or payable to the Adviser.

In addition, pursuant to the Investment Management Agreement and the administration agreement of the Company (the “Administration Agreement”), we will reimburse the Adviser and Administrator for certain expenses as they occur. For the year ended December 31, 2023, the Administrator charged approximately $1.8 million for certain costs and expenses allocable to the Company under the terms of the Administration Agreement. For the period from

19

January 27, 2022 (Inception) to December 31, 2022, the Administrator charged approximately $518,000 for certain costs and expenses allocable to the Company under the terms of the Administration Agreement.

Each of the Investment Management Agreement and the Administration Agreement has been approved by the Board. Unless earlier terminated, each of the Investment Management Agreement and the Administration Agreement will remain in effect for a period of two years from the date it first became effective and will remain in effect from year-to-year thereafter if approved annually by a majority of the Board, including a majority of Independent Trustees, or by the holders of a majority of our outstanding voting securities (as defined by the 1940 Act) and, in each case, a majority of the Independent Trustees.

Resource Sharing Agreement

The Adviser is a registered investment adviser under the Advisers Act. The Company’s investment activities are managed by its investment adviser, which is responsible for (i) originating prospective investments, (ii) conducting research and due diligence investigations on potential investments, (iii) analyzing investment opportunities, (iv) negotiating and structuring the Company’s investments, and (v) monitoring the Company’s investments and portfolio companies on an ongoing basis.

The Adviser has entered into a resource sharing agreement with TPG Angelo Gordon (the “Resource Sharing Agreement”), pursuant to which TPG Angelo Gordon will provide the Adviser with experienced investment professionals and access to the resources of TPG Angelo Gordon to enable the Adviser to fulfill its obligations under the Investment Management Agreement.  Through the Resource Sharing Agreement, the Adviser intends to capitalize on the significant deal origination, credit underwriting, due diligence, investment structuring, execution, portfolio management and monitoring experience of TPG Angelo Gordon’s investment professionals.

Several of the Company’s executive officers and the Company’s Chairman of the Board have ownership and financial interests in TPG Angelo Gordon. The Company’s Chief Executive Officer also serves as the Portfolio Manager of several TPG Angelo Gordon funds that currently and in the future will have investment objectives similar to ours. In addition, the Company’s executive officers and Trustees serve or may serve as officers, directors or principals of entities that operate in the same or related line of business as we do or of investment funds, accounts, or investment vehicles managed by TPG Angelo Gordon and/or its affiliates. Similarly, TPG Angelo Gordon and its affiliates may have other clients with similar, different or competing investment objectives.

Co-Investment Relief

An affiliate of the Adviser has received an exemptive order from the SEC that permits the Company, among other things, to co-invest with certain other persons, including certain affiliates of the Adviser and certain funds managed and controlled by the Adviser and its affiliates, subject to certain terms and conditions. Pursuant to such order, the Company’s Board of Trustees may establish objective criteria (“Board Criteria”) clearly defining co-investment opportunities in which the Company will have the opportunity to participate with other public or private TPG Angelo Gordon funds that target similar assets. If an investment falls within the Board Criteria, TPG Angelo Gordon must offer an opportunity for the Company to participate. The Company may determine to participate or not to participate, depending on whether the Adviser determines that the investment is appropriate for the Company (e.g., based on investment strategy). The co-investment would generally be allocated to us and the other TPG Angelo Gordon funds that target similar assets pro rata based on available capital in the applicable asset class. If the Adviser determines that such investment is not appropriate for the Company, the investment will not be allocated to the Company, but the Adviser will be required to report such investment and the rationale for its determination for the Company to not participate in the investment to the Board of Trustees at the next quarterly board meeting.

License Agreement

The Company also entered into a trademark license agreement with TPG Angelo Gordon under which TPG Angelo Gordon has agreed to grant the Company a non-exclusive, royalty-free license to use the name “TPG Angelo Gordon” and other similar related marks.

The Private BDC Merger

In connection with the Company’s merger with AGTB Private BDC (the “Private BDC”), on December 30, 2022, the Company and the Private BDC entered into an Agreement and Plan of Merger (the “Private BDC Merger Agreement”). The Boards of Trustees of both the Company and Private BDC, in each case, including the majority of the trustees who are not “interested persons” (as such term is defined in the 1940 Act), approved the Private BDC Merger Agreement and the transactions contemplated thereby, consistent with the requirements under Rule 17a-8 of the 1940 Act.

Pursuant to the Private BDC Merger Agreement, the Company and Private BDC caused the merger to be consummated by filing a certificate of merger (the “Private BDC Certificate of Merger”) with the Secretary of State of the State of Delaware on December 30, 2022. The merger became effective on January 1, 2023 (the “Private BDC Effective Time”), as agreed to by the parties and specified in the Private BDC Certificate of Merger.

At the Private BDC Effective Time, common shares of beneficial interest, par value $0.001 per share, of Private BDC outstanding immediately prior to the Private BDC Effective Time were converted into a number of the Company’s Class I shares of beneficial interest, par value $0.001 per share, equal to a ratio of one to one.

The AGTB Merger

In connection with the Company’s merger with AG Twin Brook BDC, Inc. (“AGTB”), on May 19, 2023, the Company and AGTB entered into an Agreement and Plan of Merger (the “AGTB Merger Agreement”). The Board of Trustees of the Company and the Board of Directors of AGTB, including the majority of the respective trustees and directors who are not “interested persons” (as such term is defined in the 1940 Act), approved the AGTB Merger Agreement and the transactions contemplated thereby, consistent with the requirements under Rule 17a-8 of the 1940 Act.

Pursuant to the AGTB Merger Agreement, the Company and AGTB caused the merger to be consummated by filing a certificate of merger (the “AGTB Certificate of Merger”) with the Secretary of State of the State of Delaware on July 28, 2023, and the merger became effective as agreed to by the parties and specified in the AGTB Certificate of Merger (the “AGTB Effective Time”). As of the AGTB Effective Time, each share of AGTB’s common stock, par value $0.001 per share, outstanding immediately prior to the AGTB Effective Time was converted into the right to receive $20.00 per share in cash, without interest, subject to any applicable withholding taxes. The Company paid cash consideration in connection with the AGTB transaction of approximately $193 million and had transaction costs of approximately $0.8 million. Prior to the AGTB transaction closing, AGTB was an affiliated BDC managed by AG Twin Brook Manager, LLC, a wholly-owned subsidiary of TPG Angelo Gordon.

Related Party Transactions

The Audit Committee conducts quarterly reviews of any potential related party transactions brought to its attention and, during these reviews, it also considers any conflicts of interest brought to its attention pursuant to the Company's Code of Conduct or Code of Ethics. Each of our Trustees and executive officers is instructed and periodically reminded to inform Compliance of any potential related party transactions.

PROPOSAL 2

RATIFICATION OF THE SELECTION OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Information about the Independent Registered Public Accounting Firm

The Audit Committee and the Board approved the engagement of Deloitte & Touche as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024 at their respective meetings held on March 19, 2024. Deloitte & Touche is the independent registered public accounting firm of TPG Inc., the parent of the Adviser. The Company knows of no direct or indirect material financial interest of Deloitte & Touche in the Company. A representative of Deloitte & Touche is expected to be available at the Annual Meeting and thus, will have an opportunity to make a statement, if they so desire, and be available to respond to appropriate questions asked by the shareholders.

During the Company’s two most recent fiscal years (fiscal years ended December 31, 2023 and 2022) and the subsequent interim period through March 21, 2024, neither the Company nor anyone on its behalf consulted Deloitte & Touche regarding (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Deloitte & Touche concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K, or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.

PricewaterhouseCoopers LLP (“PwC”) acted as the Company’s independent registered public accounting firm for each of the fiscal years ended December 31, 2022 and 2023. The Company knows of no direct financial or material indirect financial interest of PwC in the Company. A representative of PwC is expected to be available to answer questions during the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so.

On March 19, 2024, the Audit Committee dismissed PwC as the Company’s independent public accounting firm, effective as of the date of the completion of the audit services for the fiscal year ended December 31, 2023. The dismissal of PwC became effective on March 21, 2024. PwC’s reports on the Company’s consolidated financial statements as of and for each of the two most recent fiscal years (fiscal years ended December 31, 2023 and 2022) did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the Company’s two most recent fiscal years (fiscal years ended December 31, 2023 and 2022) and the subsequent interim period through March 21, 2024, there were no (i) disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to the satisfaction of PwC, would have caused PwC to make reference thereto in its reports covering the Company’s consolidated financial statements for such periods and (ii) reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K).

The following table presents fees for professional services rendered by PwC to the Company for the fiscal years ended December 31, 2023 and December 31, 2022. The table does not include fees for any services provided by PwC to AGTB Private BDC or AG Twin Brook BDC, Inc., the Company’s predecessors. All services provided by PwC to the Company were pre-approved in accordance with the Company’s policies and procedures. The audit services are pre-approved by the Audit Committee pursuant to an audit engagement letter, and, in accordance with the Company’s pre-approval policies and procedures, the Audit Committee of the Company must pre-approve all non-audit services (other than certain de minimis exceptions) provided by PwC, and all non-audit services (other than certain de minimis exceptions) provided by PwC to the Adviser, or any entity controlling, controlled by, or under common control with the Adviser that provides ongoing services to the Company (collectively, the “Adviser Entities”) if such services relate directly to the operations and financial reporting of the Company. In addition to the non-audit services reported under “All Other Fees” in the table below, during the year ended December 31, 2023, PwC billed $160,000 in non-audit fees to the Adviser Entities for services related to attestation services over internal controls over custody of assets for syndicated loans. During the year ended December 31, 2022, PwC did not provide non-audit services to the Adviser Entities that were subject to pre-approval by the Audit Committee.

Audit Committee Report

The following is the report of the audit committee (the “Audit Committee”) of the board of trustees (the “Board”) of AG Twin Brook Capital Income Fund (the “Company”) with respect to the Company’s audited financial statements for the year ended December 31, 2023.

The Audit Committee oversees the Company’s accounting and financial reporting processes and the audits of the Company’s financial statements. Management is responsible for the preparation, presentation, and integrity of the Company’s financial statements, the Company’s accounting and financial and reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The Audit Committee reviewed the audited financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “Form 10-K”) with management and discussed the quality of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee has considered and discussed the above described December 31, 2023 audited financial statements with management and with PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm (“PwC”). The Audit Committee has also discussed with PwC the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”). The Audit Committee reviewed with PwC, who is responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgment as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards. Finally, the Audit Committee reviewed the written disclosures and the letters from PwC required by the PCAOB, as currently in effect, has considered whether the provision of other non-audit services by PwC to the Company are compatible with maintaining PwC’s independence, and has discussed with PwC its independence of the Company.

The Audit Committee discussed with PwC the overall scope and plans for the audit. The Audit Committee met with PwC to discuss the results of their audit, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

Based upon the reports and discussions described in this report, and subject to the limitations on the role and responsibilities of the Audit Committee referred to in this Proxy Statement and in the Audit Committee Charter available on the Company’s website, www.AGTBCAP.com, under the heading “Resources,” the Audit Committee recommended to the Board (and the Board has approved) that the Company’s audited financial statements be included in the Form 10-K and filed with the Securities and Exchange Commission.

Shareholders are reminded, however, that the members of the Audit Committee are not professionally engaged in the practice of auditing or accounting. Members of the Audit Committee rely, without independent verification, on the information provided to them and on the representations made by management and PwC. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions, referred to above, do not assure that the audit of the Company’s financial statements has been carried out in accordance with the standards of the PCAOB, that the financial statements are presented in conformity with accounting principles generally accepted in the U.S. or that the Company’s independent registered public accounting firm is, in fact, “independent.”
