Thornburg Income Builder Opportunities Trust Announces Distribution

Thornburg Income Builder Opportunities Trust (NASDAQ: TBLD) announced its monthly distribution.

SANTA FE, NM - July 1, 2022 - Thornburg Income Builder Opportunities Trust (the "Trust") (NASDAQ: TBLD) today announced a monthly distribution of $0.10417 per share on the Trust's common shares, payable on July 20, 2022 to common shareholders of record as of July 11, 2022.

The Trust's monthly distributions are shown below:

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 July 20, 2022, does not include a return of capital but includes short-term capital gains in the amount of $0.05049. The specific tax characteristics of the distributions will be reported to the Trust's common shareholders on Form 1099 after the end of the 2022 calendar year. The final determination for all distributions paid in 2022 will be made in early 2023 and reported to you on Form 1099-DIV. You should not use this notice as a substitute for your 1099-DIV.

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.
