About AllianceBernstein National Municipal Income Fund
AllianceBernstein National Municipal Income Fund, Inc. is a New York Stock Exchange-listed closed-end municipal bond fund trading under the ticker AFB. It is managed by AllianceBernstein L.P. and is headquartered at its principal office at 66 Hudson Boulevard East, New York, New York. The Fund seeks high current income that is exempt from regular U.S. federal income tax by investing all of its net assets in tax-exempt municipal securities; it normally invests at least 80% of net assets in municipal securities and at least 75% in investment-grade or comparable-quality securities.
Unlike an operating company, AFB does not report conventional product revenue, gross margin, employee headcount, or corporate P/E metrics. Its more relevant valuation and operating indicators are net asset value (NAV), net investment income, portfolio composition, leverage, and distributions. As of July 31, 2026, AFB had total net assets of $339.1 million, NAV of $11.80 per common share, and 28.74 million common shares outstanding.

Beat or Miss?
No analyst-consensus EPS, revenue estimate, formal earnings-surprise measure, or comparable management outlook was included in the September 25 release. The most meaningful comparison is therefore against the prior quarter and prior-year period.
| Metric | Reported | Difference/Analysis |
| Net investment income | $4.71 million | Increased from $4.31 million in Q2 FY2026 and $4.02 million in Q3 FY2025 |
| Net investment income per share | $0.16 | Increased from $0.15 sequentially and $0.14 year over year |
| Net realized/unrealized gain (loss) | ($6.63 million) | Loss widened from ($2.18 million) in Q2, but narrowed substantially from ($15.78 million) a year earlier |
| NAV per common share | $11.80 | Declined from $12.01 in Q2 but improved from $11.23 in Q3 FY2025 |
| Total net assets | $339.07 million | Down from $345.32 million sequentially; up from $322.75 million year over year |
| Analyst estimate/consensus | N/A | The release contained no analyst forecasts or beat/miss comparison |
The key positive was the improvement in recurring portfolio income. The main negative was the quarterly mark-to-market and realized/unrealized loss, which reduced NAV during the three months.
What Leadership Is Saying
The Q3 earnings announcement did not include CEO or CFO commentary, named executive quotations, an earnings-call transcript, or detailed forward-looking management discussion. The Fund is managed by AllianceBernstein L.P., and its earlier shareholder report describes the portfolio approach and investment mandate.
“The Fund seeks to provide high current income exempt from regular federal income tax by investing substantially all of its net assets in municipal securities that pay interest that is exempt from federal income tax.”
“The Team continues to focus on real after-tax return by investing in municipal bonds that generate income exempt from federal income taxes.”
For an investor-focused interpretation, the Fund’s management approach remains centered on tax-exempt income and municipal-credit selection rather than quarterly operating growth. The semiannual shareholder report also noted that leverage can amplify both NAV and market-price volatility, especially when interest rates rise or borrowing costs increase.
Historical Performance
| Category | Q3 FY2026 | Q3 FY2025 | Change (%) |
| Net investment income | $4.71 million | $4.02 million | 17.30% |
| Net investment income per share | $0.16 | $0.14 | 14.30% |
| Net realized and unrealized gain (loss) | ($6.63 million) | ($15.78 million) | Loss narrowed 58.0% |
| Net realized/unrealized loss per share | ($0.23) | ($0.55) | Loss per share narrowed 58.2% |
| Total net assets | $339.07 million | $322.75 million | 5.10% |
| NAV per common share | $11.80 | $11.23 | 5.10% |
| Common shares outstanding | 28.74 million | 28.74 million | 0.00% |
AFB’s annual and semiannual reporting confirms that its performance is particularly sensitive to interest-rate changes, municipal-credit conditions, duration exposure, and leverage. For the 12 months ended April 30, 2026, the Fund reported a 7.62% NAV return versus 6.34% for the Bloomberg Municipal Bond Index, while its market-price return was 12.50%. Historical returns do not guarantee future performance.
Competitor Comparison
A direct peer comparison is not available from the Q3 release because municipal closed-end funds have different fiscal calendars, portfolio mandates, leverage structures, state/geographic concentrations, and reporting dates. AFB also did not publish a competitor benchmark table.
| Category | AFB Q3 FY2026 | AFB Q3 FY2025 | Change (%) |
| Net investment income | $4.71 million | $4.02 million | 17.30% |
| Net realized/unrealized loss | ($6.63 million) | ($15.78 million) | Loss narrowed 58.0% |
| NAV per common share | $11.80 | $11.23 | 5.10% |
| Total net assets | $339.07 million | $322.75 million | 5.10% |
For a more relevant comparative framework, investors should evaluate AFB against national municipal closed-end fund peers on: NAV return, market-price return, discount or premium to NAV, tax-equivalent distribution rate, effective leverage, duration, credit quality, state exposure and the percentage of below-investment-grade holdings. The Bloomberg Municipal Bond Index is the Fund’s disclosed broad benchmark, although it does not reflect leverage, fees or active management.
How the Market Reacted?
The earnings release did not disclose an immediate stock-price or after-hours market reaction. Available end-of-day market data referenced in coverage showed AFB at approximately $9.75 on September 25, 2026, down $0.02, or 0.20%, on the day; however, this should not be treated as a confirmed earnings-specific reaction because the announcement was published after the regular market close.
Overall sentiment is mixed: recurring net investment income improved both sequentially and year over year, while the Fund’s NAV fell during the quarter because realized and unrealized portfolio losses exceeded income. The latest distribution declaration of $0.05018 per share provides a near-term income reference point, but the sustainability and market value of distributions remain exposed to municipal-bond pricing, rates, credit conditions, and leverage costs.
