BBN - BlackRock Taxable Municipal Bond Trust

What this means for you

Sit Investment is known for pushing closed-end funds to narrow the gap between price and value. For now it has told the regulator it is not seeking changes. One other large investor owns more than 5% of this fund and has said the same; that is common for banks, brokers and index funds that hold shares for their clients.

Nothing is required of you. If an investor changes its mind, it must file a new notice within days, and it will show up here.

About this fund

• Run by BlackRock Advisors, LLC. Part of the BlackRock-advised Funds fund family. As of Dec 31, 2025, from the fund's yearly report. Original document →
• Size: about $1.05 billion of holdings, as of June 30, 2026. As of June 30, 2026, from the fund's quarterly holdings report. Original document →
• Borrowing: the fund borrows about 36% on top of its own money, as of June 30, 2026. Borrowed money makes gains and losses bigger. As of June 30, 2026, from the fund's quarterly holdings report. Original document →
• Costs: 0.8% a year in management fees; 3.1% a year in total, including interest on borrowed money. Fiscal year ended Dec 31, 2025. As of Dec 31, 2025, from the fund's yearly report. Original document →
  Among the 76 funds we follow that invest in tax-free municipal bonds, 53 charge a lower management fee and 38 charge less in total, at their last yearly reports. Both numbers are measured against the fund's own money, not the money it borrows on top, so a fund that borrows more shows higher costs on both counts.
• The fund's own cost example: $1,000 invested costs about $45 in the first year and about $384 over 10 years, assuming the holdings return 5% a year. As of Dec 31, 2023, from the fund's annual report. Original document →
• Payouts: last fiscal year (ended Dec 31, 2025) the fund paid $1.14 a share. $0.99 of that was income; $0.15 was your own money back, not income. Most funds announce their monthly or quarterly payout on their own website, not in a filing with the regulator, so a cut or a raise there does not show up here until the next yearly report. A few funds do file a notice about a fixed payout; those appear under What happened, and when. As of Dec 31, 2025, from the fund's annual report. Original document →
• Value of holdings per share at the last fiscal year end (Dec 31, 2025): $17.28. The shares traded at $16.32, about 5.6% below that. As of Dec 31, 2025, from the fund's yearly report. Original document →
  Over the last two years the gap (a "discount" when the price is below the value) ranged from 10.6% below to 7% above. As of Dec 31, 2023, from the fund's annual report. Original document →
• How the holdings did: up 1.3% over the last three months we have (April-June 2026), before the share price is taken into account. As of June 30, 2026, from the fund's quarterly holdings report. Original document →
• First reported to the regulator in 2010.

• Borrowing: about 35% on top of its own money at Dec 31, 2025; 32% at Dec 31, 2024; 31% at Dec 31, 2023. From the fund's quarterly holdings reports. Original documents: Dec 31, 2025 →, Dec 31, 2024 →, Dec 31, 2023 →.
• The fund had about 61.8 million shares at Dec 31, 2025, about the same as at Dec 31, 2023.As of Dec 31, 2025, from the fund's annual report. Original document →

What these lines mean: a payout that is your own money back, what a fund costs, borrowing.

What a holder made

• The year ended Dec 31, 2025: the shares returned +8.5%, counting payouts; the holdings +7.9%. The holdings figure is what the fund's investments earned, before the share price is taken into account. As of Dec 31, 2025, from the fund's annual report. Original document →
• The year ended Dec 31, 2024: the shares returned +6%, counting payouts; the holdings +1.5%. As of Dec 31, 2024, from the fund's annual report. Original document →
• The year ended Dec 31, 2023: the shares returned +3.6%, counting payouts; the holdings +12%. As of Dec 31, 2023, from the fund's annual report. Original document →
• The year ended Dec 31, 2022: the shares returned -31%, counting payouts; the holdings -26.6%. As of Dec 31, 2022, from the fund's annual report. Original document →
• Those four years together: the shares returned -17.9%. $10,000 of shares bought at the start (Jan 1, 2022) would have become about $8,210 by Dec 31, 2025, with every payout counted, before tax. As of Dec 31, 2025, from the fund's annual report. Original document →
• The holdings over the last twelve months we have, to June 30, 2026: +6.2%. The quarterly reports carry no share price, so this is the holdings alone. As of June 30, 2026, from the fund's quarterly holdings report. Original document →
• Of the 54 funds that invest in tax-free municipal bonds with a fiscal year ending within six months of this one, 18 reported a higher share return for that year and 35 a lower one. As of Dec 31, 2025, from the fund's annual report. Original document →
• A past year says nothing about the next one. All figures are the fund's own, from its reports to the regulator.

Why the shares and the holdings can differ: the gap between price and value. Why payouts count: a payout that is your own money back.
