SANTA FE, N.M., Aug. 1, 2025 /PRNewswire/ -- Thornburg Income Builder Opportunities Trust (the "Trust") ((TBLD) today announced a monthly distribution of $0.10417 per share on the Trust's common shares, payable on August 20, 2025, to common shareholders of record as of August 11, 2025.

The Trust's monthly distribution is shown below:

Amount	Payable Date	Ex-Dividend/Record Date	Change from Previous Declaration
$0.10417	August 20, 2025	August 11, 2025	No Change

Distribution rates are not performance and are calculated by summing the Trust's monthly distribution per share over four quarters and dividing by the net asset value or market price per share, as applicable, as of the distribution announcement date. Distributions on common shares are generally paid from net investment income (regular interest and dividends) and may also include capital gains and/or a return of capital. The Trust's distribution payable on August 20, 2025, includes a short-term capital gain and does not include a return of capital or a long-term capital gain. The specific tax characteristics of the distributions will be reported to the Trust's common shareholders on Form 1099 after the end of the 2025 calendar year. The final determination for all distributions paid in 2025 will be made in early 2026 and reported to you on Form 1099-DIV. You should not use this notice as a substitute for your 1099-DIV.

The Trust's fiscal year (10/01/2024 through 09/30/2025) cumulative distributions are shown below:

	Current Distribution	Cumulative Distributions FYTD
Net Investment Income	$0.04322 (41 %)	$0.94248 (82 %)
Net Realized Short-term Capital Gain	$0.06095 (59 %)	$0.13800 (12 %)
Net Realized Long-term Capital Gain	$0.00000 (0 %)	$0.06539 (6 %)
Return of Capital or Other Capital Sources	$0.00000 (0 %)	$0.00000 (0 %)
Total per share	$0.10417 (100 %)	$1.14587 (100 %)

Shareholders should not assume that the source of a distribution from the Trust is net income or profit. A distribution comprised in whole or in part by a return of capital does not necessarily reflect the Trust's investment performance and should not be confused with "yield" or "income." Future distributions may consist of a return of capital. For further information regarding the Trust's distributions, please visit www.thornburg.com/tbld-distributions.

The Trust's investment objective is to provide current income and additional total return. The Trust seeks to achieve its objective by investing, directly or indirectly, at least 80% of its managed assets in a broad range of income-producing securities. The Trust invests in both equity and debt securities of companies located in the United States and around the globe. The Trust may invest in non-U.S. domiciled companies, including up to 20% of its managed assets at the time of investment in equity and debt securities of emerging market companies.

As a registered investment company, the Trust is subject to a 4% excise tax that is imposed if the Trust does not distribute to common shareholders by the end of any calendar year at least the sum of (i) 98% of its ordinary income (not taking into account any capital gain or loss) for the calendar year and (ii) 98.2% of its capital gain in excess of its capital loss (adjusted for certain ordinary losses) for a one-year period generally ending on October 31 of the calendar year (unless an election is made to use the Trust's fiscal year). In certain circumstances, the Trust may elect to retain income or capital gain to the extent that the Board of Trustees, in consultation with Trust management, determines it to be in the interest of shareholders to do so.

The common share distributions paid by the Trust for any particular period may be more than the amount of net investment income from that period. As a result, all or a portion of a distribution may be a return of capital, which is in effect a partial return of the amount a common shareholder invested in the Trust, up to the amount of the common shareholder's tax basis in their common shares, which would reduce such tax basis. Although a return of capital may not be taxable, it will generally increase the common shareholder's potential gain, or reduce the common shareholder's potential loss, on any subsequent sale or other disposition of common shares.
