PROSPECTUS SUPPLEMENT

(To Prospectus dated February 12, 2025)

77,000,000 Shares

Invesco Senior Income Trust

77,000,000 Common Shares

March 21, 2025

Invesco Senior Income Trust (the “Fund”), a diversified, closed-end management investment company, is offering up to 77,000,000 of its common shares of beneficial interest, no par value (the “Common Shares”), pursuant to this prospectus supplement.

The Fund has entered into a distribution agreement dated January 31, 2025 (the “Distribution Agreement”) with Invesco Distributors, Inc. (“Invesco Distributors”), an affiliate of the Fund and Invesco Advisers Inc., (“Invesco” or the “Adviser”), the Fund’s investment adviser, to provide for distribution of the Fund’s Common Shares. Invesco Distributors has entered into a sub-placement agent agreement dated March 21, 2025 (the “Sub-Placement Agent Agreement”) with JonesTrading Institutional Services LLC (“JonesTrading” or “Sub-Placement Agent”) with respect to the Fund relating to the Common Shares offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the Sub-Placement Agent Agreement, the Fund may offer and sell its Common Shares from time to time through the Sub-Placement Agent as its exclusive sub-placement agent for the offer and sale of its Common Shares offered by this prospectus supplement and the accompanying prospectus.

Under the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund may not sell any Common Shares at a price below the current net asset value (“NAV”) per share of such Common Shares plus the per share amount of any distributing commission or discount. The Fund or Invesco Distributors will suspend the sale of Common Shares if the per share price of the Common Shares is less than such minimum price. The Fund currently intends to distribute the Common Shares offered pursuant to this prospectus supplement primarily in negotiated transactions or through transactions deemed “at the market,” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on the New York Stock Exchange (the “NYSE”) or sales made to or through a market maker other than on an exchange at prices related to the prevailing market prices or at negotiated prices. For information on how Common Shares may be sold, see the “Plan of Distribution” section of this prospectus supplement.

The Fund will compensate Invesco Distributors with respect to sales of Common Shares at a commission rate of up to 1.00% of the gross proceeds of the sale of the Fund’s Common Shares. Out of this amount, Invesco Distributors will compensate the Sub-Placement Agent at a rate of up to the full 1.00% of the gross sales proceeds of the sale of the Fund’s Common Shares sold by the Sub-Placement Agent. In connection with the sale of the Common Shares on the Fund’s behalf, Invesco Distributors may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of Invesco Distributors may be deemed to be underwriting commissions or discounts.

Common Shares are listed on the NYSE. The trading or “ticker” symbol of the Common Shares is “VVR.” The closing price of the Common Shares, as reported by the NYSE on March 17, 2025, was $4.05 per Common Share. The NAV of the Common Shares at the close of business on that same date was $3.77 per Common Share.

Common shares of closed-end investment companies, such as the Fund, often trade at a discount to their NAV. This creates a risk of loss for an investor purchasing common shares in a public offering.

Investing in the Common Shares involves risks. See “Risks” beginning on page 11 of the accompanying prospectus. You should consider carefully these risks together with all of the other information in this prospectus supplement and the accompanying prospectus before making a decision to purchase Common Shares.

The date of this prospectus supplement is March 21, 2025.

You should read this prospectus supplement, together with the accompanying prospectus, which contains important information about the Fund, before deciding whether to invest in Common Shares and retain it for future reference. A statement of additional information, dated February 12, 2025, and as it may be supplemented (the “SAI”), containing additional information about the Fund, has been filed with the SEC and is incorporated by reference in its entirety into this prospectus supplement and the accompanying prospectus. This prospectus supplement, the accompanying prospectus and the SAI are part of a “shelf” registration statement filed with the SEC.

Other expenses⁽⁷⁾		0.47	%

⁽²⁾

Assuming a Common Share offering price of $4.05 (the Fund’s closing price on the NYSE on March 17, 2025). Assumes all of the Common Shares being offered by this Prospectus Supplement and the accompanying prospectus are sold. Represents the initial offering costs incurred by the Fund in connection with this offering, which are estimated to be $162,686.

⁽⁵⁾

The Fund pays the Adviser an annual fee, payable monthly, in an amount equal to 0.85% of the Fund’s average daily Managed Assets. The fee shown above is based upon outstanding leverage of 29% of the Fund’s total assets. If leverage of more than 29% of the Fund’s total assets is used, the management fees shown would be higher.

⁽⁶⁾

Based upon the Fund’s outstanding borrowings of approximately $128,000,000 and $72,000,000, respectively and outstanding preferred shares as of August 31, 2024 of approximately $100,000, and the average daily weighted interest rate for the fiscal period ended August 31, 2024 of 6.35% and 8.17%, respectively and dividends on preferred shares at an annual rate of 5.58%.

⁽⁷⁾

Other expenses are based on estimated amounts for the current fiscal year.

The purpose of the table and the example below is to help you understand the fees and expenses that you, as a Common Shareholder, would bear directly or indirectly.

Example

The following example illustrates the expenses, including the applicable transaction fees (referred to as the “Maximum Sales Charge” in the fee table above), and estimated offering costs that you would pay on a $1,000 investment in Common Shares, assuming (1) “Total annual expenses” of 5.26% of net assets attributable to Common Shares and (2) a 5% annual return*:

		1 Year				3 Years				5 Years				10 Years
Total Expenses paid by Common Shareholders		$	62			$	166			$	269			$	524

* The Example should not be considered a representation of future expenses or returns. Actual expenses may be higher or lower than those assumed. Moreover, the Fund’s actual rate of return may be higher or lower than the hypothetical 5% return shown in the example. The example assumes that all dividends and distributions are reinvested at net asset value.

S-3

USE OF PROCEEDS

Assuming the sale of all of the Common Shares offered under this Prospectus Supplement and the accompanying prospectus, at the last reported sale price of $4.05 per share for Common Shares on the NYSE as of March 17, 2025, the Fund estimates that the net proceeds of this offering will be approximately $308,568,815 after deducting the estimated sales charge and the estimated offering expenses payable by the Fund. There is no guarantee that there will be any sales of Common Shares pursuant to this Prospectus Supplement and the accompanying prospectus. Actual sales, if any, of Common Shares under this Prospectus Supplement and the accompanying prospectus may be less than as set forth above. In addition, the price per share of any such sale may be greater or less than the price set forth above, depending on the market price of Common Shares at the time of any such sale. As a result, the actual net proceeds the Fund receives may be more or less than the amount of net proceeds estimated in this Prospectus Supplement.

The net proceeds from the issuance of Common Shares hereunder will be invested in accordance with the Fund’s investment objective and policies as set forth in the accompanying prospectus. It is currently anticipated that the Fund will be able to invest substantially all of the net proceeds of an offering of Common Shares in accordance with its investment objective and policies within three to six months after the completion of any such offering or the receipt of such proceeds, depending on the availability of appropriate investment opportunities consistent with the Fund’s investment objective and market conditions. Pending such investment, it is anticipated that the proceeds will be invested in cash, cash equivalents or other securities, including U.S. government securities or high quality, short-term debt securities. The Fund may also use the proceeds for working capital purposes, including the payment of distributions, interest and operating expenses, although the Fund currently has no intent to issue Common Shares primarily for this purpose. See “Use of Leverage” in the accompanying prospectus.

MARKET AND NET ASSET VALUE INFORMATION

The following table sets forth, for each of the periods indicated: (i) the high and low closing market prices for the Common Shares reported as of the end of the day on the NYSE, (ii) the high and low net asset value (NAV) of the Common Shares, and (iii) the high and low of the premium or discount to NAV (expressed as a percentage) of shares of the Common Shares. NAV is generally determined on each day that the NYSE is open for business. See “Net Asset Value” in the accompanying prospectus for information as to the determination of the Fund’s NAV. The Board of Trustees, in consultation with the Adviser, will review periodically the possibility of open market repurchases and/or other options (such as tender offers) to reduce any material discount from NAV in respect of the Common Shares. There are no assurances that the Board will, in fact, decide to undertake either of these actions or if undertaken, that such actions will result in the Fund’s Common Shares trading at a price which is equal to or approximates their NAV.
