BlackRock TCP Capital Corp

Annual Meeting of Stockholders

This proxy statement (the “Proxy Statement”) is furnished in connection with the solicitation of proxies by the Board of Directors (the “Board of Directors”) of BlackRock TCP Capital Corp., a Delaware corporation (the “Company”), for use at the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) of the Company to be held on May 22, 2025, at 9:00 a.m. Pacific Time, and at any postponements, adjournments or delays thereof. Stockholders will not have to travel to attend the Annual Meeting but will be able to view the Annual Meeting live and cast their votes by accessing a web link. However, stockholders will have the same rights in the virtual meeting as they would in in-person meetings. To attend the Annual Meeting please follow the directions below and use the following link: meetnow.global/M4N5VLR.

We encourage you to access the Annual Meeting prior to the start time. The live webcast and listen-only conference call will begin promptly at 9:00 a.m. Pacific Time. The virtual meeting platform is fully supported across browsers (Internet Explorer, Firefox, Chrome, and Safari) and devices (desktops, laptops, tablets, and cell phones) running the most updated version of applicable software and plugins. You will not be able to attend the Annual Meeting in person. Participants should ensure that they have a strong WiFi connection wherever they intend to participate in the Annual Meeting. Participants should also give themselves plenty of time to dial-in to the conference call or log in and ensure that they can hear audio prior to the start of the Annual Meeting.

If you want to submit a question during the Meeting, log into the live webcast at meetnow.global/M4N5VLR, click on the “Q&A” icon at the top right of your screen, type a question or comment in the free form section and click “Send” to submit your question

If your shares in the Company are registered in your name, you may attend and participate in the Annual Meeting at meetnow.global/M4N5VLR by entering the control number found in the shaded box on your proxy card on the date and time of the Annual Meeting. You may vote during the Annual Meeting by following the instructions that will be available on the Annual Meeting website during the Annual Meeting.

If you are a beneficial stockholder of the Company (that is if you hold your Company shares through a bank, broker, financial intermediary or other nominee) and want to attend the Annual Meeting you must register in advance of the Annual Meeting. To register, you must submit proof of your proxy power (legal proxy) reflecting your Company holdings along with your name and email address to Georgeson LLC, the Company’s tabulator. You may email an image of your legal proxy to shareholdermeetings@computershare.com. Requests for registration must be received no later than 5:00 p.m. (Eastern time) three business days prior to the Annual Meeting date. You will receive a confirmation email from Georgeson LLC of your registration and a control number and security code that will allow you to vote at the Annual Meeting. This Proxy Statement, the accompanying proxy card and the Company’s Annual Report for the fiscal year ended December 31, 2024 are first being sent to stockholders on or about April 9, 2025.

It is important that every stockholder authorize a proxy so that we can achieve a quorum and hold the Annual Meeting. The presence at the Annual Meeting, in person via webcast or by proxy, of holders of not less than one-third of the Company’s shares issued and outstanding and entitled to vote at the meeting will constitute a quorum for the transaction of business. If a quorum is not met, then we will be required to adjourn the meeting and incur additional expenses to continue to solicit additional votes.

We have engaged a proxy solicitor, who may call you and ask you to vote your shares. The proxy solicitor will not attempt to influence how you vote your shares, but only ask that you take the time to cast a vote. You may also be asked if you would like to authorize your proxy over the telephone and to have your voting instructions transmitted to our proxy tabulation firm.

We encourage you to vote, either by voting virtually at the Annual Meeting or by granting a proxy (i.e., authorizing someone to vote your shares). If you properly sign and date the accompanying proxy card or authorize a proxy to vote your shares by telephone or through the Internet, and we receive it in time for the Annual Meeting, the persons named as proxies will vote the shares registered directly in your name in the manner that you specified. If you properly execute the proxy card and give no instructions on the proxy card, the shares covered by the proxy card will be voted FOR the election of the nominees as Directors and FOR the proposal to authorize the Company, with the approval of its Board of Directors, to sell its common shares at a price or prices below the Company’s then current net asset value per share in one or more offerings (for up to the next 12 months), subject to certain limitations set forth herein (including, without limitation, that the number of shares sold on any given date does not exceed 25% of the Company’s then outstanding common stock immediately prior to such sale).

If you are a stockholder “of record” (i.e., you hold shares directly in your name), you may revoke a proxy at any time before it is exercised by notifying the Company’s Chief Compliance Officer in writing, by submitting a properly executed, later-dated proxy, or by voting virtually at the Annual Meeting. Any stockholder of record attending the Annual Meeting may vote virtually whether or not he or she has previously authorized a proxy.

If your shares are held for your account by a broker, trustee, bank or other institution or nominee, you may vote such shares at the Annual Meeting only if you have a legal proxy and present it at the Annual Meeting.

If your shares are registered in the name of a bank or brokerage firm, you may be eligible to vote your shares electronically via the Internet or by telephone.
