Regulation FD Disclosure (Form 8-K)

Item 7.01 Regulation FD Disclosure.

Effective March 5, 2026, Nuveen AMT-Free Quality Municipal Income Fund (the "Fund") extended the final mandatory redemption date of its Series 4 Variable Rate Demand Preferred Shares, aggregate liquidation preference $489.5 million, from September 11, 2026 to September 11, 2056.

Dividends on the Variable Rate Demand Preferred Shares currently are set weekly at a rate established by a remarketing agent appointed by the Fund, subject to a maximum rate that will increase over time in the event of an extended period of unsuccessful remarketing. Each series includes a liquidity feature provided by a liquidity provider that allows a holder of the Variable Rate Demand Preferred Shares to have its shares purchased by the liquidity provider in the event that a sell order by the holder has not been matched with a purchase order and successfully settled in a remarketing.

The Series 4 Variable Rate Demand Preferred Shares are preferred shares of the Fund and are senior, with priority in all respects, to the Fund's common shares in liquidation and as to the payment of dividends; the Variable Rate Demand Preferred Shares of each series rank on parity with each other and any other outstanding preferred shares of the Fund.

The Series 4 Variable Rate Demand Preferred Shares have not been registered under the Securities Act of 1933 (the "Securities Act") or any state securities laws. Unless so registered, no Variable Rate Demand Preferred Shares may be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws. This Regulation FD disclosure is neither an offer to sell nor a solicitation of an offer to buy any of these securities.
