Here are the 424B prospectus supplements from Blackrock Muni Assets Fund, Inc. (MUA) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow MUA and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full MUA filings page.
BlackRock MuniAssets Fund, Inc. is conducting a transferable rights offering to existing common shareholders, registering up to 16,784,940 new common shares. One right will be issued for each common share held as of the July 28, 2026 record date, and three rights are needed to buy one new share, with a special one-share minimum for holders of fewer than three shares. The rights trade on the NYSE under “MUA RT” and may be exercised until 5:00 p.m. ET on August 20, 2026, with an over‑subscription privilege for fully participating record holders, subject to pro rata allotment and possible elimination by the board.
The subscription price will be the lower of 95% of the 5‑day average market price around expiration or 90% of NAV on the expiration date; the estimated price is $10.04 per share, implying gross proceeds of about $168.5 million if fully subscribed. All offering expenses, estimated at $324,847, will be paid by the adviser, so the fund receives full subscription proceeds. Non‑participating shareholders will experience ownership and potential NAV dilution, especially if shares are issued below NAV, though rights are transferable and can be sold for value. The fund expects added assets to reduce leverage (from about 32.33% to 26.99% of managed assets) and be invested over roughly three months in its core strategy of tax‑exempt municipal bonds.
