Nuveen is asking common and preferred shareholders of Nuveen New Jersey Quality Municipal Income Fund (NXJ), Nuveen Pennsylvania Quality Municipal Income Fund (NQP), a Nuveen Missouri municipal fund, and Nuveen Municipal High Income Opportunity Fund (NMZ) to approve a merger of the three state funds into NMZ, with shareholders receiving newly issued NMZ common and preferred shares.
As of July 31, 2025, the combined fund would have common assets of 2,120,784,666 and managed assets of 3,368,142,306. Post-merger, NMZ’s common earnings yield is shown at 6.17%, compared with pre-merger yields of about 3.30–3.54% for the target funds, and total expense ratios are projected to fall to 3.51% for the combined fund.
The materials highlight potential secondary-market benefits such as bid/ask spread improvements and higher average daily trading volume, plus discount narrowing based on three-year averages. They also note trade-offs: preferred shareholders will lose existing “state tax gross-up” features, and the combined portfolio will reflect NMZ’s lower-rated municipal credit profile, albeit with combined leverage of about 42.04% and preferred share coverage of 334.24% as of July 31, 2025.

Nuveen is asking shareholders of three single-state municipal funds (NXJ, NQP, and the Missouri fund) to approve a merger into Nuveen Municipal High Income Opportunity Fund (NMZ). The combined fund would have common assets of 2,120,784,666 and managed assets of 3,368,142,306 as of July 31, 2025, creating a larger, nationally diversified portfolio.
For common shareholders, the materials highlight higher post-merger common earnings yields for the target funds (for example, NQP rising from 3.54% to NMZ’s 6.17%) and higher taxable equivalent rates, along with total expense reductions of up to 1.42%. They also show potential secondary market benefits such as narrower average discounts, tighter bid/ask spreads, and higher average daily trading volume.
Preferred shareholders are told that NMZ preferred shares will not retain the existing “state tax gross-up” feature, but the combined structure would have a leverage ratio of 42.04% and preferred share coverage of 334.24% as of July 31, 2025. The funds also emphasize diversification, with NMZ holding 909 positions as of December 31, 2025, and reiterate that all projections are subject to typical investment and market risks.

Nuveen is asking shareholders to approve a merger of three state-specific municipal funds into Nuveen Municipal High Income Opportunity Fund (NMZ). Common shares of Nuveen New Jersey Quality Municipal Income Fund (NXJ), Nuveen Pennsylvania Quality Municipal Income Fund (NQP), and Nuveen Missouri Quality Municipal Income Fund would be exchanged for newly issued NMZ common shares, with all four funds’ preferred shareholders also voting.
As of July 31, 2025, the combined fund would have about $3.37 billion in managed assets, with NMZ representing 53.9% of that total. Post‑merger, the projected common earnings yield for NXJ, NQP and the Missouri fund rises to 6.17%, implying gains of roughly 2.6–2.9 percentage points, while taxable equivalent rates for those funds increase by about 3.6–4.3 percentage points.
Total expense ratios are expected to decline for each target fund, with indicated savings of 0.34% for NXJ, 0.24% for NQP and 1.42% for the Missouri fund, and bid/ask spreads and average daily trading volume are shown improving. However, preferred shareholders moving into NMZ will lose existing state tax gross‑up provisions, and the combined portfolio will hold more lower‑rated municipal securities, reflecting NMZ’s credit profile, though it will also be more diversified, with 909 holdings as of December 31, 2025.
