How the business works
Municipal-bond interest after expenses and financing costs becomes net investment income. Credit losses and changing bond prices affect net asset value separately.

Reported earnings and sources
Reported earnings for the latest four periods. Compare the same earnings measure across periods; different measures are not added together.
Cash distributions are the total paid per share during each reporting period, including any gains or return of capital. Period lengths may differ, so compare the dates before comparing amounts. Short periods are not annualized.
NAV change excludes distributions. Reported NAV total return includes reinvestment and is copied from the fund statement, not estimated by adding cash distributions to the NAV change.
Why the annual trend is limited
The income and distribution trend ends with fiscal 2025 because NMZ absorbed three municipal funds in April 2026. The six months ended April 2026 include that change and are not another comparable full year. Follow the next complete post-merger report to judge the current portfolio's income support.
Cash paid, opening and closing NAV, and the fund-reported NAV total return are separate observations. NAV change excludes distributions. These figures show outcomes, not which source funded a payment or whether future distributions are sustainable. Net investment income excludes investment gains and is not a payout-coverage ratio.
Fund net investment income per common share; actual reporting period, not annualized$0.2800
$0.00$0.30
For the six months ended April 30, 2026, NMZ reported $0.28 of net investment income and $0.39 of distributions per share. Net asset value fell from $10.61 to $10.37. This half-year crosses the April 2026 fund mergers, so it belongs on its own rather than being joined to the five complete pre-merger years as one unchanged strategy trend.
Bond interest, less expenses and financing costs, is the central recurring income source. A declared distribution can include gains or return of capital as well as investment income; its amount is not an earnings figure.
The earnings available to shareholders depend on the cash generated by these activities after operating and financing costs. Portfolio gains, financing proceeds and recurring income should be evaluated separately.
The portfolio information checked September 11, 2026 reports effective leverage of 41.21%.
Financing can increase earning assets, but its cost reduces income available to common shareholders. When borrowing costs rise or portfolio income falls, the distribution can become harder to sustain.
Nuveen Municipal High Income Opportunity Fund reported $0.2800 per share for 2025-11-01 through 2026-04-30, measured as Fund net investment income per common share; actual reporting period, not annualized.
Actual per-share reporting period, without annualisation. Net investment income, realized gains, unrealized changes and cash distributions are different measures. This comparison is not the Fly High forward Dividend Coverage Ratio.
Losses or weaker cash generation in municipal credit can reduce the resources available for future distributions.
Watch for changes in the underlying exposure and the next reported results before treating the current payment as evidence of continuing earnings support.
A maintained payment can exceed investment results. Review NAV and reported income together rather than treating distribution yield as total return.
