#### PROXY STATEMENT

#### 2026 Virtual Annual Meeting of Stockholders
This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors (the "Board" and each member, a "Director") of MidCap Financial Investment Corporation, a Maryland corporation (the "Company," "we," "us" or "our"), for use at the Company's 2026 Annual Meeting of Stockholders (the "Meeting") to be held on Thursday, June 18, 2026 at 10:00 a.m., Eastern Time, virtually at www.virtualshareholdermeeting.com/MFIC2026 and at any postponements or adjournments thereof. To participate in the Meeting virtually, you will need the Control Number included on your proxy card. Please note that those using the dial-in number for the listen-only conference call will not be able to vote or submit questions. This Proxy Statement, the Notice of Virtual Annual Meeting of Stockholders, the accompanying proxy card and the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, will be made available to stockholders via the Internet on or about April 30, 2026.

We encourage you to access the Meeting prior to the start time. The live webcast and listen-only conference call will begin promptly at 10:00 a.m. Eastern Time. We will have technicians ready to assist you with any technical difficulties you may have accessing the live webcast or listen-only conference call. If you encounter any difficulties accessing the Meeting during check-in or the Meeting itself, please call the technical support number that will be posted on the Meeting platform log-in page at www.virtualshareholdermeeting.com/MFIC2026. Technical support will be available starting at 9:45 a.m., Eastern Time, on June 18, 2026 and will remain available until thirty minutes after the Meeting has finished. The Meeting platform is fully supported across browsers (Edge, Firefox, Chrome, and Safari) and devices (desktops, laptops, tablets, and cell phones) running the most updated version of applicable software and plugins. Participants should ensure that they have a strong Wi-Fi connection wherever they intend to participate in the Meeting. Participants should also give themselves plenty of time to dial into the conference call or log in and ensure that they can hear audio prior to the start of the Meeting.

We encourage you to vote your shares by following the instructions on the Notice of Internet Availability of Proxy Materials and granting a proxy (i.e., authorizing someone to vote your shares). If you provide voting instructions, either via the Internet, by telephone or by requesting, signing, dating and returning a proxy card, and the Company receives them in time for the Meeting, the persons named as proxies will vote your shares in the manner that you specified. **If you give no instructions on the proxy card you execute, the shares covered by the proxy card will be voted FOR the election of the nominees as Directors and FOR the ratification of the Company's independent registered public accounting firm.**

You may revoke a proxy at any time before it is exercised by notifying the Company's Secretary in writing, by submitting a properly executed later-dated proxy, or by participating in the Meeting and voting online. Participating in the Meeting does not revoke your proxy unless you also vote online at the Meeting.

If your shares are registered in the name of a bank, brokerage firm or other nominee, you will receive instructions from your bank, broker or other nominee that you must follow in order to instruct how your shares are to be voted at the Meeting.

If you want to submit a question during the Meeting, log into the live webcast at <u>www.virtualshareholdermeeting.com/MFIC2026</u>, type your question into the "Ask a Question" field, and click "Submit."

------

Only questions submitted via the live webcast that are pertinent to Meeting matters will be answered during the Meeting, subject to time constraints. **Please note that no questions may be submitted via the listen-only conference call.** Questions or comments that are not related to the proposals under discussion, are about personal concerns not shared by stockholders generally, or use blatantly offensive language may be ruled out of order. Additionally, the Company may not be able to answer multiple questions submitted by the same stockholder. Questions pertinent to Meeting matters that cannot be answered during the Meeting due to time constraints will be posted online and answered at www.virtualshareholdermeeting.com/MFIC2026.

Web links throughout this document are provided for convenience only, and the content on the referenced websites does not constitute a part of, and is not otherwise incorporated by reference into, this proxy statement.

#### Purpose of Meeting
At the Meeting, you will be asked to vote on the following proposals:

1. To consider and vote upon the election of two Class I Directors of the Company, who will each serve until the Company's 2029 Annual Meeting of Stockholders and until their successors are duly elected and qualified;

2. To consider and vote upon ratifying the selection of Deloitte & Touche LLP ("Deloitte") to serve as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026; and

3. To transact such other business as may properly come before the Meeting and any postponement or adjournment thereof.

#### Voting Securities
You may vote your shares at the Meeting only if you were a stockholder of record at the close of business on April 22, 2026 (the "Record Date"). There were 82,372,628 shares of the Company's common stock outstanding (the "Shares") on the Record Date. Each Share is entitled to one vote on each matter to be voted on at the Meeting. Stockholders do not have the right to cumulate votes in the election of Directors.

#### Quorum Required
A quorum must be present at the Meeting for any business to be conducted. The presence at the Meeting, in person (virtually), or by proxy, of holders of Shares entitled to cast a majority of the votes entitled to be cast on the Record Date will constitute a quorum. Abstentions and broker non-votes will be deemed to be present for the purpose of determining a quorum for the Meeting. Those stockholders accessing the Meeting via the listen-only conference call will not be deemed to be "present" for purposes of determining a quorum for the Meeting. If a stockholder of the Company does not vote electronically via the live webcast or does not submit voting instructions to its broker, bank or other nominee, the broker, bank or other nominee will not be permitted to vote the stockholder's shares on non-routine proposals. The ratification of the selection of Deloitte as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026 (Proposal 2) is considered routine under applicable rules. The election of Directors (Proposal 1) is considered non-routine under applicable rules. For non-routine proposals, a broker, bank or other nominee that holds shares in street name on behalf of a stockholder must receive voting instructions from the beneficial owner of the shares in order for the shares to be voted at the Meeting. A "broker non-vote" with respect to a matter occurs when a broker, bank or other nominee holding shares on behalf of a beneficial owner has not received voting instructions from the beneficial owner on a particular proposal and does not have, or chooses not to exercise, discretionary authority to vote the shares on such proposals. **Please note that to be sure your vote is counted on the Company's proposal to elect Directors, 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.**

------

#### Vote Required
*Election of Directors*. The election of a Director requires the affirmative vote of a majority of the total votes cast for and affirmatively withheld as to such nominee. If you vote "Withhold Authority" with respect to a nominee, your Shares will not be voted with respect to the person indicated. **Because Directors are elected by an affirmative vote of the majority of the total votes cast for and affirmatively withheld, votes to withhold authority will have the effect of a vote against a nominee. Broker non-votes will not be included in determining the number of votes cast and as a result will have no effect on this proposal.**

*Ratification of Independent Registered Public Accounting Firm.* The affirmative vote of a majority of the votes cast at the Meeting virtually or by proxy is required to ratify the appointment of Deloitte to serve as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. **Abstentions and broker non-votes, if any, will not be included in determining the number of votes cast and as a result will have no effect on this proposal.**

*Additional Solicitation.* If there are not enough shares represented at the Meeting for a quorum or votes to approve or ratify a proposal at the Meeting, the Executive Chairman of the Meeting may adjourn the Meeting to permit the further solicitation of proxies.

A stockholder vote may be taken on any proposal in this Proxy Statement prior to any such adjournment if a quorum is present and there are sufficient votes for approval of such proposal.

#### Authorizing a Proxy for Shares Held in Your Name
If you are a record holder of Shares, you may authorize a proxy to vote on your behalf by following the instructions provided on the Notice of Internet Availability of Proxy Materials. Authorizing your proxy will not limit your right to participate in the Meeting and vote your Shares online. A properly completed and submitted proxy will be voted in accordance with your instructions unless you subsequently revoke your instructions. If you authorize a proxy without indicating your voting instructions, the proxyholder will vote your Shares according to the Board's recommendations. Internet and telephone voting procedures are designed to authenticate the stockholder's identity and to allow stockholders to vote their Shares and confirm that their instructions have been properly recorded. Your Internet or telephone vote authorizes the named proxies to vote your Shares in the same manner as if you had marked, signed and returned a proxy card.

#### Revoking Your Proxy
If you are a stockholder of record, you can revoke your proxy at any time before it is exercised by: (i) delivering a written revocation notice that is received prior to the Meeting to MidCap Financial Investment Corporation at 9 West 57th Street, New York, New York 10019, Attention: Secretary; (ii) submitting a later-dated proxy that we receive before the conclusion of voting at the Meeting; or (iii) participating in the Meeting and voting online. If you hold Shares through a broker, bank, trustee or nominee, you must follow the instructions you receive from them in order to revoke your voting instructions. Participating in the Meeting does not revoke your proxy unless you also vote online at the Meeting.

#### Information Regarding This Solicitation
The Company will bear the expense of the solicitation of proxies for the Meeting. The Company has retained Georgeson LLC ("Georgeson") to assist in the solicitation of proxies. The Company expects to pay market rates for such services, with an estimated fee of approximately $9,500, plus expenses. As the Meeting date approaches, certain stockholders of the Company may receive a telephone call from a representative of Georgeson if their proxy authorizations have not yet been received. Authorization to permit Georgeson to execute proxies may be obtained by telephonic or electronically transmitted instructions from stockholders of the Company. Proxies that are obtained telephonically will be recorded in accordance with the procedures described

------

below. The Company believes that these procedures are reasonably designed to ensure that both the identity of the stockholder casting the vote and the voting instructions of the stockholder are accurately determined.

In all cases where a telephonic proxy is solicited, the Georgeson representative is required to ask each stockholder to confirm his or her full name and to confirm a portion of the address that appears on the stockholder's account registration. The Georgeson representative will ask the stockholder to confirm that he or she has either received the proxy materials in the mail or has been provided a notice and access notification. If the stockholder is a corporation or entity, the Georgeson representative is required to ask for the person's title and confirmation that the person is authorized to direct the voting of the shares. If the information solicited matches the information provided to Georgeson, then the Georgeson representative has the responsibility to explain the process, read the proposals listed on the proxy card and ask for the stockholder's instructions on the proposals. Although the Georgeson representative is permitted to answer questions about the process, he or she is not permitted to recommend to the stockholder how to vote, other than to read any recommendation set forth in this Proxy Statement. Georgeson will record the stockholder's instructions electronically and submit the instructions electronically to be tabulated. The stockholder will be sent a letter to confirm his or her proxy authorization and provide instructions for making corrections if his or her voting instructions are not correctly reflected in the confirmation.

We have requested that brokers, nominees, fiduciaries and other persons holding Shares in their names, or in the names of their nominees, which are beneficially owned by others, forward the proxy materials to, and obtain proxies from, such beneficial owners. We will reimburse such persons for their reasonable expenses in so doing.

In addition to mail and email, proxies may be solicited personally via the Internet or by telephone or facsimile transmission by Directors or officers of the Company or officers or employees of Apollo Investment Management, L.P., our investment adviser ("AIM" or the "Investment Adviser") (without special compensation). AIM is located at 9 West 57th Street, New York, New York 10019.

#### Security Ownership of Certain Beneficial Owners and Management
As of the Record Date, to our knowledge, no person would be presumed under the Investment Company Act of 1940, as amended (the "1940 Act"), to "control" us, as such term is defined in the 1940 Act.

Our Directors consist of independent Directors (Directors who are not "interested persons" (as defined in the 1940 Act) of the Company, and therefore not affiliates of AIM) ("Independent Directors") and interested Directors ("Interested Directors"). Interested Directors are "interested persons" of the Company, as defined in the 1940 Act.

As of the Record Date, based on public filings and/or information, we believe that no stockholder, directly or indirectly owned, controlled or held, with the power to vote, 5% or more of our Shares. The following table sets forth our affiliates that directly or indirectly owned, controlled or held, with the power to vote, our Shares as of the Record Date. Unless otherwise indicated, we believe that each beneficial owner set forth in the table has sole voting and investment power over the securities owned by it.

#### PROPOSAL 1: ELECTION OF DIRECTORS
Pursuant to the Company's charter and bylaws, the Board may modify the number of members of the Board provided that the number thereof shall never be less than four nor more than ten. In accordance with the bylaws, the Company currently has seven members on the Board. Directors are divided into three classes and are generally elected for staggered terms of three years each, with a term of office of one of the three classes of Directors expiring each year. The Company may have cause to propose a term of less than three years for a Director as it may deem necessary. Each Director will hold office for the term to which he or she is elected or until his or her successor is duly elected and qualified.

A stockholder can vote for, or withhold his or her vote from, any Nominee. In the absence of instructions to the contrary, it is the intention of the persons named as proxies to vote such proxy FOR the election of the Nominees named below. If a Nominee should decline or be unable to serve as a Director, it is intended that the proxy will be voted for the election of such person as is nominated by the Board as a replacement. The Board has no reason to believe that any of the persons named below will be unable or unwilling to serve.

#### THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF THE NOMINEES NAMED IN THIS PROXY STATEMENT.

#### Information about the Nominees and Directors
Certain information with respect to the Class I nominees for election at the Meeting, as well as each of the other Directors who are not standing for re-election, is set forth below, including their names, ages, a brief description of their recent business experience, including present occupations and employment, certain directorships that each person held during the last five years, and the year in which each person became a Director of the Company.

Emanuel Pearlman and Tanner Powell each have been nominated for election for a three-year term expiring at the Company's 2029 Annual Meeting of Stockholders and until his successor is duly elected and qualified.

#### THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF THE NOMINEES NAMED IN THIS PROXY STATEMENT.

------

#### Corporate Governance
*Director Independence*. NASDAQ rules require listed companies to have a board of directors with at least a majority of Independent Directors. Under NASDAQ rules, in order for a director to be deemed independent, the board of directors must determine that the individual does not have a relationship that would interfere with the director's exercise of independent judgment in carrying out his or her responsibilities. On an annual basis, each member of our Board is required to complete an independence questionnaire designed to provide information to assist the Board in determining whether the Director is independent under NASDAQ rules and our corporate governance guidelines. Our Board has determined that each of our Directors and Nominees, other than Messrs. Hannan and Powell and Ms. Whonder, are independent under the listing standards of NASDAQ Marketplace Rule 5605(a)(2). Our governance guidelines require any Director who has previously been determined to be independent to inform the Executive Chairman of the Board, the Chairman of the Nominating and Corporate Governance Committee and our Corporate Secretary of any change in circumstance that may cause his or her status as an Independent Director to change. The Board limits membership on the Audit Committee and the Nominating and Corporate Governance Committee to Independent Directors.

*Board of Directors' Oversight Role in Management.* The Board's role in management of the Company is oversight. As is the case with virtually all investment companies, including externally managed business development companies such as the Company (as distinguished from operating companies), service providers to the Company, primarily AIM, Apollo Investment Administration, LLC ("AIA" or the "Administrator") and their affiliates, have responsibility for the day-to-day management of the Company, which includes responsibility for risk management (including management of investment performance and investment risk, valuation risk, issuer and counterparty credit risk, compliance risk and operational risk). As part of its oversight, the Board, acting at its scheduled meetings, or the Executive Chairman or the lead Independent Director acting between meetings, regularly interacts with and receives reports from senior personnel of service providers, including the Company's Chief Executive Officer, its President and its Chief Financial Officer (or a senior representative of their respective offices), the Company's and AIM's Chief Compliance Officer and portfolio management personnel. The Audit Committee of the Board (which consists of all Independent Directors) meets regularly, and between meetings the Audit Committee Chair maintains contact with the Company's independent registered public accounting firm, the Company's Chief Financial Officer and the internal auditor. In addition, at its quarterly meetings, the Audit Committee meets with the independent valuation service providers that evaluate certain of the Company's securities holdings for which there are not readily available market values. The Board also receives periodic presentations from senior personnel of AIM or its affiliates regarding risk management generally, as well as periodic presentations regarding specific operational, compliance or investment areas such as business continuity, personal trading, valuation, credit and investment research. The Board has adopted policies and procedures designed to address certain risks of the Company. In addition, the Company, AIM, AIA and other service providers to the Company have adopted a variety of policies, procedures and controls designed to address particular risks to the Company. However, it is not possible to eliminate all of the risks applicable to the Company. The Board also receives reports from counsel to the Company or counsel to AIM and the Board's own independent legal counsel regarding regulatory compliance and governance matters. The Board oversight role does not make the Board a guarantor of the Company's investments or activities or the activities of any of the Company's service providers on behalf of the Company.

*Board of Directors Composition and Leadership Structure.* The 1940 Act requires that at least a majority of the Company's Directors be Independent Directors. Currently, four of the Company's seven Directors are Independent Directors. The Executive Chairman and Vice Chairman of the Board are interested persons of the Company, and the Independent Directors have designated a lead Independent Director, Mr. Stein, who chairs meetings or executive sessions of the Independent Directors, reviews and comments on Board meeting agendas, represents the views of the Independent Directors to management and facilitates communication among the Independent Directors and their counsel and between management and the Independent Directors. The Board has determined that its leadership structure, in which over 60% of the Directors are not affiliated with AIM, is appropriate in light of the services that AIM and its affiliates provide to the Company and potential conflicts of interest that could arise from these relationships.

------

*Information About Each Director's Experience, Qualifications, Attributes or Skills*. Additional information about each Director follows (supplementing the information provided in the table above) that describes some of the specific experiences, qualifications, attributes or skills that each Director possesses which the Board believes has prepared them to be effective Directors. The Board believes that the significance of each Director's experience, qualifications, attributes or skills is an individual matter (meaning that experience that is important for one Director may not have the same value for another) and that these factors are best evaluated at the board level, with no single Director, or particular factor, being indicative of board effectiveness. However, the Board believes that Directors need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Company management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties; the Board believes that its members satisfy this standard. Experience relevant to having this ability may be achieved through a Director's educational background; business, professional training or practice (e.g., medicine, accounting or law), public service or academic positions; experience from service as a board member (including the Board of the Company) or as an executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences. To assist them in evaluating matters under federal and state law, the Directors are counseled by their own independent legal counsel, who participates in Board meetings and interacts with AIM, and also may benefit from information provided by the Company's or AIM's counsel; both Board and Company counsel have significant experience advising funds and fund board members. The Board and its Committees have the ability to engage other experts as appropriate. The Board evaluates its performance on an annual basis.

For the fiscal year ended December 31, 2025, the Board held four board meetings, four Audit Committee meetings, four Nominating and Corporate Governance Committee meetings and one Compensation Committee meeting. Each Director attended at least 75% of the combined number of meetings of the Board and meetings of committees on which he or she served during the fiscal year ended December 31, 2025.

The Company requires each Director to make a diligent effort to attend all Board and committee meetings, and encourages Directors to attend the annual meeting of stockholders. At the 2025 annual meeting of stockholders, all of the Directors attended virtually.

*Audit Committee.* The Audit Committee operates pursuant to an Audit Committee Charter approved by the Board. The charter sets forth the responsibilities of the Audit Committee, which include selecting or retaining each year an independent registered public accounting firm (the "auditors") to audit the annual financial statements of the Company; reviewing and discussing with management and the auditors the annual audited financial statements of the Company, including disclosures made in management's discussion and analysis, and recommending to the Board whether the audited financial statements should be included in the Company's

------

annual report on Form 10-K; reviewing and discussing with management and the auditors the Company's quarterly financial statements prior to the filing of its quarterly reports on Form 10-Q; pre-approving the auditors' engagement to render audit and/or permissible non-audit services; evaluating the qualifications, performance and independence of the auditors; reviewing preliminary valuations of our Investment Adviser and independent valuation firms and recommending valuations to the Board; and recommending compensation of the Chief Financial Officer to the Board for determination. The Audit Committee is composed of each of the Independent Directors, whom, after the Meeting will be: Messrs. Pearlman, Reinfrank and Stein and Ms. Matas all of whom also are otherwise considered independent under NASDAQ Marketplace Rule 5605(a)(2). Ms. Matas serves as the Chairperson of the Audit Committee. The Board has determined that Messrs. Pearlman and Reinfrank and Ms. Matas each qualify as an "audit committee financial expert" as that term is defined under Item 401 of Regulation S-K under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Audit Committee Charter is available on the Company's website (<u>www.midcapfinancialic.com</u>).

*Nominating and Corporate Governance Committee*. The Nominating and Corporate Governance Committee is responsible for selecting qualified nominees to be elected to the Board by stockholders; identifying, selecting or recommending qualified nominees to fill any vacancies on the Board or a committee thereof; developing and recommending to the Board a set of corporate governance principles applicable to the Company; overseeing the evaluation of the Board and management; and undertaking such other duties and responsibilities as may from time to time be delegated by the Board to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee is composed of each of the Independent Directors, whom, after the Meeting will be: Messrs. Pearlman, Reinfrank and Stein and Ms. Matas. Mr. Reinfrank currently serves as the Chairman of the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee has adopted a written Nominating and Corporate Governance Committee Charter, which is available on the Company's website (<u>www.midcapfinancialic.com</u>).

The Nominating and Corporate Governance Committee will consider stockholder recommendations for possible nominees for election as Directors when such recommendations are submitted in accordance with the Company's current bylaws, the Nominating and Corporate Governance Committee Charter and any applicable law, rule or regulation regarding Director nominations. Nominations should be sent to Kristin Hester, Corporate Secretary, MidCap Financial Investment Corporation, 9 West 57<sup>th</sup> Street, New York, New York 10019. To have a candidate considered by the Nominating and Corporate Governance Committee, a stockholder must submit the recommendation in writing and must include the following information:

• The name of the stockholder and evidence of the person's ownership of Company stock, including the number of shares owned and the length of time of the ownership;

• The name of the candidate, the candidate's resume or a listing of his or her qualifications to be a Director of the Company and the person's consent to be named as a Director if selected by the Nominating and Corporate Governance Committee and nominated to the Board; and

• If requested by the Nominating and Corporate Governance Committee, a completed and signed Director's Questionnaire.

Criteria considered by the Nominating and Corporate Governance Committee in evaluating the qualifications of individuals for election as members of the Board include, to the extent required, compliance with the independence and other applicable requirements of the federal securities laws, the listing standards of NASDAQ, and any other applicable laws, rules, or regulations; the ability to contribute to the effective management of the Company, taking into account the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with the Company's management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties; the educational background, business, professional training or practice (e.g., medicine, accounting or law), public service or academic positions, experience from service as a board member (including the Board) or as an executive of investment funds, public companies or significant private or not-for-profit entities or other organizations, and/or

------

other life experiences; and personal and professional integrity, character, time availability in light of other commitments, dedication, conflicts of interest and such other relevant factors that the Nominating and Corporate Governance Committee considers appropriate. The Board also believes it is appropriate for members of the Company's management to serve as a member of the Board. In addition, although the Nominating and Corporate Governance Committee does not have a formal policy with regard to consideration of diversity in identifying Director candidates, the Nominating and Corporate Governance Committee may consider whether a potential candidate's professional experience, education, skills and other individual qualities and attributes, including gender, race or national origin, would provide beneficial diversity of skills, experience or perspective to the Board's membership and collective attributes. Such considerations will vary based on the Board's existing membership and other factors, such as the strength of a potential nominee's overall qualifications relative to diversity considerations.

*Compensation Committee*. The Compensation Committee is responsible for determining, or recommending to the Board for determining, the compensation of our Chief Executive Officer and all other executive officers, paid directly by us, if any. The Compensation Committee also assists the Board with all matters related to compensation, as directed by the Board. The Compensation Committee is composed of each of the Independent Directors, whom, after the Meeting will be: Messrs. Pearlman, Reinfrank and Stein and Ms. Matas, each of whom is not an interested person of us for purposes of the 1940 Act and the NASDAQ corporate governance rules. As shown below, none of our executive officers is directly compensated by us and, as a result, the Compensation Committee does not produce and/or review and report on executive compensation practices. The Compensation Committee Charter is available on our website (<u>www.midcapfinancialic.com</u>).

*Co-Investment Committee*. The Co-Investment Committee is responsible for reviewing and approving certain co-investment transactions pursuant to the exemptive order we received from the U.S. Securities and Exchange Commission (the "Commission") on May 14, 2025 (the "Order"). The Co-Investment Committee is comprised of all the Independent Directors.

#### Compensation of Executive Officers
None of the Company's executive officers receive direct compensation from the Company. The Company does not engage any compensation consultants. The compensation of the principals and other investment professionals of the Investment Adviser is paid by the Investment Adviser. Compensation paid to the Company's Chief Financial Officer and Chief Compliance Officer is set by the Administrator and is subject to reimbursement by the Company of the allocable portion of such compensation for services rendered to the Company. Compensation paid to the Chief Compliance Officer is also approved by the Board, including a majority of the Independent Directors, in accordance with Rule 38a-1 under the 1940 Act.

#### Policies and Practices Related to the Timing of Equity Awards
The Company does not grant options, and accordingly, we have no policy, program, practice, or plan pertaining to the timing of stock option grants with respect to the release of material non-public information. Furthermore, given that we do not directly compensate our executive officers, we also have not timed the release of material non-public information for the purpose of affecting the value of executive compensation.

#### Certain Relationships and Transactions
Transactions with Affiliated Persons. We have entered into an amended and restated investment advisory and management agreement with AIM. Certain of our Executive Officers and our Chairman of the Board have ownership and financial interests in AIM. Certain of our Executive Officers also serve as principals of other investment managers affiliated with AIM that may in the future manage investment funds with investment objectives similar to ours. In addition, our Executive Officers and Directors and the partners of AIM 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 managed by its affiliates, although we may not be given the opportunity to participate in certain investments made by investment funds managed by advisers affiliated with AIM. However, our Investment Adviser and its affiliates intend to allocate investment opportunities in a fair and equitable manner consistent with our investment objectives and strategies so that we are not disadvantaged in relation to any other client. We may invest, to the extent permitted by law, on a concurrent basis with affiliates of AIM, subject to compliance with applicable regulations and our allocation procedures.

We have entered into a royalty-free license agreement with AGM, pursuant to which AGM has agreed to grant us a non-exclusive license to use the name "Apollo." Under the license agreement, we have the right to use the "Apollo" name for so long as AIM or one of its affiliates remains our investment adviser. In addition, we rent office space from AIA, an affiliate of AIM, and pay Apollo Administration our allocable portion of overhead and other expenses incurred by AIA in performing its obligations under our administration agreement with AIA, including our allocable portion of the cost of our Chief Financial Officer, Chief Compliance Officer, Chief Legal Officer and their respective staffs, which can create conflicts of interest that our Board must monitor.

On August 1, 2022, the Company changed its name from "Apollo Investment Corporation" to "MidCap Financial Investment Corporation". As a result, we have entered into a trademark license agreement with Apollo Capital Management, L.P., which grants us a non-exclusive license to use the name "MidCap Financial."

With respect to Director independence, please refer to the Corporate Governance section herein.

#### PROPOSAL II: RATIFICATION OF

#### SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
At a meeting held on February 25, 2026 the Company's Audit Committee approved and the Board, including a majority of the Independent Directors, approved and ratified the selection of Deloitte as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. The Company expects that a representative of Deloitte will be present virtually at the Meeting, and will have an opportunity to make a statement (if the representative so desires) and to respond to appropriate questions. After reviewing the Company's audited financial statements for the fiscal year ended December 31, 2025, the Audit Committee recommended to the Board that such statements be included in the Company's Annual Report on Form 10-K. A copy of the Audit Committee's Report appears below.

#### Fees Paid
**Audit Fees**: Audit fees consist of fees billed for professional services rendered for the audit of our year-end financial statements and services that were normally provided by Deloitte in connection with statutory and regulatory filings. Audit fees billed during the fiscal years ended December 31, 2025 and December 31, 2024 were $1,071,125 and $1,238,375, respectively.

**Audit-Related Fees**: Audit-related services consist of fees billed by Deloitte for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are not reported under "Audit Fees." These services include attest services that are not required by statute or regulation and consultations concerning financial accounting and reporting standards. Audit-related fees billed during the fiscal years ended December 31, 2025 and December 31, 2024 were $10,000 and $50,000, respectively.

**Tax Services Fees**: Tax services fees consist of fees billed by Deloitte for professional tax services. These services also include assistance regarding federal, state, and local tax compliance. Tax services fees billed during the fiscal years ended December 31, 2025 and December 31, 2024 were $950.25 and $740.25, respectively. Tax services fees include work related to, among other things, preparation of annual reporting related to the Foreign Account Tax Compliance Act and the Common Reporting Standard.

**All Other Fees**: Other fees would include fees billed by Deloitte for products and services other than the services reported above, of which there were none during the fiscal years ended December 31, 2025 and December 31, 2024.

#### Audit Committee Pre-Approval Policy
The Audit Committee has established a pre-approval policy that describes the permitted audit, audit-related, tax and other services to be provided by Deloitte, the Company's auditors. The policy requires that the Audit Committee pre-approve the audit and non-audit services performed by the auditors in order to assure that the provision of such service does not impair the auditors' independence.

Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the Audit Committee for specific pre-approval, and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings of the Audit Committee. However, the Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated reports any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee does not delegate its responsibilities to pre-approve services performed by the independent auditor to management.

------

All services described above under "Audit-Related Fees" and "Tax Services Fees" were pre-approved by the Audit Committee.

**THE BOARD, BASED ON THE APPROVAL AND RECOMMENDATION OF THE AUDIT COMMITTEE, UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR RATIFICATION OF DELOITTE & TOUCHE LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM TO THE COMPANY FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026.**

#### Audit Committee Report
The following is the report of the Audit Committee with respect to the Company's audited financial statements for the fiscal year ended December 31, 2025.

The Audit Committee has reviewed and discussed the Company's audited financial statements with management and Deloitte, the Company's independent registered public accounting firm for the fiscal year ended December 31, 2025, with and without management present. The Audit Committee included in its review results of Deloitte's examinations, the Company's internal controls, and the quality of the Company's financial reporting. The Audit Committee also reviewed the Company's procedures and internal control processes designed to ensure full, fair and adequate financial reporting and disclosures, including procedures for certifications by the Company's Chief Executive Officer and Chief Financial Officer that are required in periodic reports filed by the Company with the Commission. The Audit Committee is satisfied that the Company's internal control system is adequate and that the Company employs appropriate accounting and auditing procedures.

The Audit Committee also has discussed with Deloitte matters relating to Deloitte's judgments about the quality, as well as the acceptability, of the Company's accounting principles as applied in its financial reporting as required by the Statement on Auditing Standards No. 1301 as amended (Communications with Audit Committee). In addition, the Audit Committee has discussed with Deloitte their independence from management and the Company, as well as the matters in the written disclosures received from Deloitte and required by applicable requirements of the PCAOB and the Commission. The Audit Committee received a letter from Deloitte confirming their independence and discussed it with them. The Audit Committee discussed and reviewed with Deloitte the Company's critical accounting policies and practices, internal controls, other material written communications to management, the scope of Deloitte audits and all fees paid to Deloitte during the fiscal year ended December 31, 2025. The Audit Committee has adopted guidelines requiring review and pre-approval by the Audit Committee of audit and non-audit services performed by Deloitte for the Company. The Audit Committee has reviewed and considered the compatibility of Deloitte's performance of non-audit services with the maintenance of Deloitte's independence as the Company's independent registered public accounting firm.

Based on the Audit Committee's review and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board of Directors has approved) that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the twelve-months ended December 31, 2025 for filing with the Commission.

#### RECEIPT OF MULTIPLE PROXY CARDS
SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for annual reports, proxy statements and notices with respect to two or more stockholders sharing the same address by delivering a single annual report, proxy statement or notice addressed to those stockholders. This process, which is commonly referred to as "householding," provides cost savings for companies. Some brokers household proxy materials, delivering a single annual report, proxy statement and notice to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Stockholders will continue to receive separate proxy cards. Once you have received notice from your broker that it will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate annual report, proxy statement and notice of internet availability of proxy materials, or if you are receiving duplicate copies of these materials and wish to have householding apply, please notify your broker. You can also request prompt delivery of a copy of the proxy statement and Annual Report by calling collect at 212-515-3200, or by writing to MidCap Financial Investment Corporation, 9 West 57th Street, New York, New York 10019, Attention: Secretary.

#### FINANCIAL STATEMENTS AND OTHER INFORMATION
The Company files periodic reports, current reports, proxy statements and other information with the Commission. This information is available on the Commission's website at www.sec.gov.
