Acquiring Fund

The
following Financial Highlights table is intended to help a prospective investor understand the Fund’s financial performance for
the periods shown. Certain information of the Fund reflects financial results for a single common share of the Fund. The total returns
in the table represent the rate an investor would have earned or lost on an investment in common shares of the Fund (assuming reinvestment
of all dividends). The Fund’s financial statements as of and for the fiscal year ended October 31, 2024, including the financial
highlights for the fiscal year then ended, have been audited by KPMG LLP (“KPMG”), an independent registered public accounting
firm. KPMG’s report, along with the Fund’s financial statements, is included in the Fund’s Annual Report. KPMG has
not reviewed or examined any records, transactions or events after the date of such reports. A copy of the Annual
Report may be obtained from www.sec.gov or by visiting www.nuveen.com. The information contained in, or that can be accessed through
the website is not part of this Joint Proxy Statement/Prospectus. Past results are not indicative of future performance.
