TriplePoint Venture Growth BDC Corp.

Rule 10b5-1 Trading Plans

During the fiscal quarter ended June 30, 2026, none of our directors or officers adopted orterminated any contract, instruction or written plan for the purchase or sale of our securities to satisfy the affirmative defense conditions of Exchange Act Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement.”

Fees and Expenses

The information in the following table is being provided to update, as of June 30, 2026, certain information in the Company’s effective shelf registration statement on Form N-2 (File No. 333-277680), declared effective by the SEC on April 18, 2024, as supplemented by the prospectus supplement relating to our Current ATM Program. The information is intended to assist you in understanding the costs and expenses that an investor in our common stock will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this Quarterly Report on Form 10-Q, or any filing under the Securities Act into which this Quarterly Report on Form 10-Q is incorporated by reference, contains a reference to fees or expenses paid by “you,” “us” or “the Company,” or that “we” will pay fees or expenses, our stockholders will indirectly bear such fees or expenses as investors in us.

Except as noted below, the following annualized percentages were calculated based on actual expenses incurred in the six months ended June 30, 2026 and net assets as of June 30, 2026, and do not include events occurring subsequent thereto. The table and examples below include all fees and expenses of our consolidated subsidiaries.

(1)The amounts set forth in this table do not reflect the impact of any sales load, sales commission or other offering expenses borne by us and our stockholders. The maximum agent commission with respect to the shares of our common stock sold by us in the Current ATM Program is 2.0% of gross proceeds, with the exact amount of such compensation to be mutually agreed upon by us and the Sales Agent from time to time. In the event that securities are sold to or through underwriters or agents, a corresponding prospectus or prospectus supplement will disclose the applicable sales load or commission.

(2)The prospectus supplement corresponding to each offering will disclose the applicable estimated amount of offering expenses, the offering price and the offering expenses borne by us as a percentage of the offering price.

(3)The expenses associated with the administration of the dividend reinvestment plan are included in “Other expenses.” The plan administrator’s fees will be paid by us. We will not charge any brokerage charges or other charges to stockholders who participate in the plan. However, your own broker may impose brokerage charges in connection with your participation in the plan.

(4)Our base management fee, payable quarterly in arrears, is calculated at an annual rate of 1.75% of our average adjusted gross assets, including assets purchased with borrowed amounts and other forms of leverage. See “Item 1. Business-Management Agreements-Investment Advisory Agreement” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for more information.

(5)Assumes that annual incentive fees earned by our Adviser remain consistent with the incentive fees that would have been earned by our Adviser (if not for the cumulative “catch-up” provision explained below) for the six months ended June 30, 2026 (annualized) adjusted for any equity issuances. The incentive fee figures set forth in this table do not take into account any waiver of the quarterly income incentive fee, which waiver is in effect through the end of the fiscal year 2026. The incentive fee consists of two components, investment income and capital gains, which are largely independent of each other, with the result that one component may be payable even if the other is not payable. Under the investment income component, we pay our Adviser each quarter 20.0% of the amount by which our pre-incentive fee net investment income for the quarter exceeds a hurdle rate of 2.0% (which is 8.0% annualized) of our net assets at the end of the immediately preceding calendar quarter, subject to a “catch-up” provision pursuant to which our Adviser receives all of such income in excess of the 2.0% level but less than 2.5% and subject to a total return requirement. The effect of the “catch-up” provision is that, subject to the total return provision discussed below, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, our Adviser receives 20.0% of our pre-incentive fee net investment income as if the 2.0% hurdle rate did not apply. The foregoing incentive fee is subject to a total return requirement, which provides that no incentive fee in respect of our pre-incentive fee net investment income is payable except to the extent that 20.0% of the cumulative net increase in net assets resulting from operations since March 5, 2014 exceeds the cumulative incentive fees accrued and/or paid since March 5, 2014. In other words, any investment income incentive fee that is payable in a calendar quarter will be limited to the lesser of (i) 20.0% of the amount by which our pre-incentive fee net investment income for such calendar quarter exceeds the 2.0% hurdle rate, subject to the “catch-up” provision and (ii) (x) 20.0% of the cumulative net increase in net assets resulting from operations since March 5, 2014 minus (y) the cumulative incentive fees accrued and/or paid since March 5, 2014. For the foregoing purpose, the “cumulative net increase in net assets resulting from operations” is the sum of our pre-incentive fee net investment income, realized gains and losses and unrealized appreciation and depreciation since March 5, 2014. Under the capital gains component of the incentive fee, we pay our Adviser at the end of each calendar year 20.0% of our aggregate cumulative realized capital gains from inception through the end of that year, computed net of our aggregate cumulative realized capital losses and our aggregate cumulative unrealized depreciation through the end of such year, less the aggregate amount of any previously paid capital gain incentive fees. For the foregoing purpose, our “aggregate cumulative realized capital gains” does not include any unrealized appreciation. It should be noted that we accrue an incentive fee for accounting purposes taking into account any unrealized appreciation in accordance with GAAP. The capital gains component of the incentive fee is not subject to any minimum return to stockholders.

(6)“Interest payments on borrowed funds” represent our estimated annual interest payment, fees and credit facility expenses and are based on results of operations for the six months ended June 30, 2026 (annualized), including with respect to the Credit Facility, the 2026 Notes, the 2027 Notes, the 8.11% 2028 Notes, and the 7.50% 2028 Notes. The costs associated with any outstanding indebtedness are indirectly borne by our common stockholders. The amount of leverage we employ at any particular time will depend on, among other things, the Board’s and our Adviser’s assessment of the market and other factors at the time at any proposed borrowing. We may also issue preferred stock, subject to our compliance with applicable requirements under the 1940 Act.

(7)“Other expenses” represent our estimated amounts for the current fiscal year, which are based upon the results of our operations for the six months ended June 30, 2026 (annualized), including payments under the Administration Agreement based on our allocable portion of overhead and other expenses incurred by our Administrator.

Example

The following example demonstrates the projected dollar amount of total cumulative expenses over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed we would have no additional leverage and that our annual operating expenses would remain at the levels set forth in the table above.

(1) Assumes no return from net realized capital gains or net unrealized capital appreciation.

While the example assumes, as required by the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. As noted, the example includes the realized capital gains fee from the Advisory Agreement but does not include the income incentive fee under the Advisory Agreement, which, assuming a 5% annual return, would either not be payable or have an immaterial impact on the expense amounts shown above. If we achieve sufficient returns on our investments to trigger an incentive fee of a material amount, our expenses, and returns to our investors, would be higher.

Further, while the example assumes reinvestment of all distributions at NAV, participants in our dividend reinvestment plan will receive a number of shares of our common stock determined by dividing the total dollar amount of the distribution payable to a participant by (a) 95% of the market price per share of our common stock at the close of trading on the payment date fixed by the Board in the event that newly issued shares of our common stock are used to implement the dividend reinvestment plan, or (b) the average purchase price of all shares of common stock purchased by the plan administrator in the event that shares are purchased in the open market to implement the requirements of the dividend reinvestment plan, which may be at, above or below NAV.

This example and the expenses in the table above should not be considered a representation of our future expenses, and actual expenses (including the cost of debt, if any, and other expenses) may be greater or less than those shown.

Price Range of Common Stock and Distributions

Our common stock is traded on the NYSE under the symbol “TPVG.” The following table shows, for each fiscal quarter during the last two full fiscal years and the current fiscal year to date, the net asset value (“NAV”) per share of our common stock, the high and low closing sales prices for our common stock, such sales prices as a percentage of NAV per share and quarterly distributions per share.

(1)NAV per share is determined as of the last day in the relevant quarter and therefore may not reflect the NAV per share on the date of the high and low sales prices. The NAVs shown are based on outstanding shares at the end of each period.

(2)Closing sales price as provided by the NYSE.

(3)Calculated as of the respective high or low closing sales price divided by the quarter-end NAV and subtracting 1.

(4)Consists of $0.23 regular quarterly distribution and $0.02 supplemental distribution.

• Not determinable at the time of filing.

On August 4, 2026, the reported closing sales price of our common stock was $$4.75 per share. As of August 4, 2026, we had 7 stockholders of record, which did not include stockholders for whom shares are held in “nominee” or “street name”.

Shares of BDCs may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that shares of our common stock will trade at a discount from NAV or at premiums that are unsustainable over the long term are separate and distinct from the risk that our NAV will decrease. It is not possible to predict whether the shares offered hereby will trade at, above or below NAV.
