NXC and NXN – Fund reorganization: On June 17, 2025, the reorganization of NXN and NXC into Nuveen Select Tax-Free Income Portfolio (NXP) was approved by the Funds’ Board of Trustees.

4 Common Share Information COMMON SHARE DISTRIBUTION INFORMATION The following information regarding the Funds' distributions is current as of August 31, 2025. Each Fund's distribution levels may vary over time based on each Fund's investment activity and portfolio investment value changes. During the current reporting period, each Fund's distributions to common shareholders were as shown in the accompanying table. Each Fund’s distribution policy, which may be changed by the Funds’ Board of Trustees, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). Each Fund intends to distribute all or substantially all of its net investment income each year through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If a distribution includes anything other than net investment income, the Fund provides a notice of the best estimate of its distribution sources at the time of the distribution which may be viewed at www.nuveen.com/CEFdistributions. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’ 1099-DIV forms after the end of the year. NUVEEN CLOSED-END FUND DISTRIBUTION AMOUNTS The Nuveen Closed-End Funds’ monthly and quarterly periodic distributions to shareholders are posted on www.nuveen.com and can be found on Nuveen’s enhanced closed-end fund resource page, which is at https://www.nuveen.com/resource-center- closed-end-funds, along with other Nuveen closed-end fund product updates. To ensure timely access to the latest information, shareholders may use a subscribe function, which can be activated at this web page ( https://www.nuveen.com/subscriptions ). Per Common Share Amounts Monthly Distributions (Ex-Dividend Date) NXC NXN March $0.0455 $0.0420 April 0.0455 0.0420 May 0.0455 0.0420 June 0.0455 0.0420 July 0.0455 0.0420 August 0.0455 0.0420 Total Distributions from Net Investment Income $0.2730 $0.2520 Yields NXC NXN Market Yield 1 4.25% 4.29% Taxable-Equivalent Yield 1 9.26% 8.87% 1 Market Yield is based on the Fund’s current annualized monthly distribution divided by the Fund’s current market price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is based on a combined federal and state income tax rate of 54.1% and 51.7% for NXC and NXN, respectively. Your actual combined federal and state income tax rate may differ from the assumed rate. The Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on payments made during the previous calendar year) that was either exempt from federal income tax but not from state income tax (e.g., income from an out-of-state municipal bond), or was exempt from neither federal nor state income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.

5 COMMON SHARE EQUITY SHELF PROGRAM During the current reporting period, NXC was authorized by the Securities and Exchange Commission to issue additional common shares through an equity shelf program (Shelf Offering). Under this program, the Fund, subject to market conditions, may raise additional capital from time to time in varying amounts and offering methods at a net price at or above the Fund’s NAV per common share. The maximum aggregate offering under this Shelf Offering is as shown in the accompanying table. During the current reporting period, NXC sold common shares through its Shelf Offering at a weighted average premium to its NAV per common share in the accompanying table. Refer to the Notes to Financial Statements for further details on Shelf Offerings and the Fund’s transactions. COMMON SHARE REPURCHASES The Funds’ Board of Trustees reauthorized an open-market share repurchase program, allowing each Fund to repurchase and retire an aggregate of up to approximately 10% of its outstanding common shares. During the current reporting period, the Funds did not repurchase any of their outstanding common shares. As of August 31, 2025, (and since the inception of the Funds’ repurchase programs), each Fund has cumulatively repurchased and retired its outstanding common shares as shown in the accompanying table. NXC Maximum aggregate offering 1,300,000 NXC Common shares sold through shelf offering 41,092 Weighted average premium to NAV per common share sold 0.16% NXC NXN Common shares cumulatively repurchased and retired - - Common shares authorized for repurchase 640,000 390,000

(b) Total Return Based on Common Share NAV is the combination of changes in common share NAV, reinvested distributions at Common Share NAV, if any. The last distribution declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending NAV. The actual reinvest price for the last distribution declared in the period may often be based on the Fund’s market price (and not its NAV), and therefore may be different from the price used in the calculation. Total returns are not annualized. Total Return Based on Common Share Price is the combination of changes in the market price per share and the effect of reinvested distributions, if any, at the average price paid per share at the time of reinvestment. The last distribution declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last distribution declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

28 Notes to Financial Statements (U naudited) 1. General Information Fund Information: The funds covered in this report and their corresponding New York Stock Exchange (“NYSE”) symbols are as follows (each a “Fund” and collectively, the “Funds”): Nuveen California Select Tax-Free Income Portfolio (NXC) Nuveen New York Select Tax-Free Income Portfolio (NXN) The Funds are registered under the Investment Company Act of 1940 (the “1940 Act”), as amended, as closed-end management investment companies. NXC and NXN were organized as Massachusetts business trusts on March 30, 1992. Current Fiscal Period : The end of the reporting period for the Funds is August 31, 2025, and the period covered by these Notes to Financial Statements is the six months ended August 31, 2025 (the "current fiscal period"). Investment Adviser and Sub-Adviser: The Fund’s investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (“TIAA”). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub- advisory agreements with Nuveen Asset Management, LLC (the “Sub-Adviser”), a subsidiary of the Adviser, under which the Sub-Adviser manages the investment portfolios of the Funds. NXC and NXN – Fund reorganization: On June 17, 2025, the reorganization of NXC and NXN into Nuveen Select Tax-Free Income Portfolio (NXP) was approved by the Funds’ Board of Trustees (the “Board”). Each merger is pending shareholder approval and satisfying other closing conditions. 2. Significant Accounting Policies The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require the use of estimates made by management and the evaluation of subsequent events. Actual results may differ from those estimates. The Funds are investment companies and follow accounting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 946, Financial Services — Investment Companies. The net asset value (“NAV”) for financial reporting purposes may differ from the NAV for processing security and common share transactions. The NAV for financial reporting purposes includes security and common share transactions through the date of the report. Total return is computed based on the NAV used for processing security and common share transactions. The following is a summary of the significant accounting policies consistently followed by the Funds. Compensation: The Funds pay no compensation directly to those of its officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Funds' Board of Trustees (the "Board") has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds. Custodian Fee Credit: As an alternative to overnight investments, each Fund has an arrangement with its custodian bank, State Street Bank and Trust Company, (the “Custodian”) whereby certain custodian fees and expenses are reduced by net credits earned on each Fund’s cash on deposit with the bank. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the Custodian. The amount of custodian fee credit earned by a Fund is recognized on the Statement of Operations as a component of “Custodian expenses, net.” During the current fiscal period, the custodian fee credit earned by each Fund was as follows: Distributions to Shareholders: Distributions to shareholders are recorded on the ex-dividend date. The amount, character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. The Funds' distribution policy, which may be changed by the Board to make regular monthly cash distributions to holders of their common shares (stated in terms of a fixed cents per common share dividend distributions rate which may be set from time to time). Each Fund intends to distribute all or substantially all of its net investment income through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, a Fund may distribute more or less than its net investment income during the period. In the event a Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. Fund Gross Custodian Fee Credits NXC $ — NXN —

29 Indemnifications: Under the Funds' organizational documents, their officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. Investments and Investment Income: Securities transactions are accounted for as of the trade date for financial reporting purposes. Realized gains and losses on securities transactions are based upon the specific identification method. Investment income is comprised of interest income, which is recorded on an accrual basis and includes accretion of discounts and amortization of premiums for financial reporting purposes. Investment income also reflects payment-in-kind (“PIK”) interest and paydown gains and losses, if any. PIK interest represents income received in the form of securities in lieu of cash. Netting Agreements: In the ordinary course of business, the Funds may enter into transactions subject to enforceable International Swaps and Derivatives Association, Inc. (ISDA) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, each Fund manages its cash collateral and securities collateral on a counterparty basis. With respect to certain counterparties, in accordance with the terms of the netting agreements, collateral posted to the Funds is held in a segregated account by the Funds’ custodian and/or with respect to those amounts which can be sold or repledged, are presented in the Funds’ Portfolio of Investments or Statement of Assets and Liabilities. The Funds’ investments subject to netting agreements as of the end of the current fiscal period, if any, are further described later in these Notes to Financial Statements. Segment Reporting: Each Fund represents a single operating segment. The officers of the Funds act as the chief operating decision maker (“CODM”). The CODM monitors the operating results of each Fund as a whole and is responsible for each Fund’s long-term strategic asset allocation in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund’s portfolio managers as a team. The financial information in the form of the Fund’s portfolio composition, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions), which are used by the CODM to assess the segment’s performance versus the Fund’s comparative benchmarks and to make resource allocation decisions for the Fund’s single segment, is consistent with that presented within the Fund’s financial statements. Segment assets are reflected on the Statement of Assets and Liabilities as “total assets” and significant segment revenues and expenses are listed on the Statement of Operations. New Accounting Pronouncement : In December 2023, the FASB issued Accounting Standard Update ("ASU") No. 2023-09, Income Taxes (Topic 740) Improvements to Income tax disclosures (“ASU 2023-09”). The primary purpose of the amendments within ASU 2023-09 is to enhance the transparency and decision usefulness of income tax disclosures primarily related to the rate reconciliation table and income taxes paid information. The amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024. Management is currently evaluating the implications of these changes on the financial statements. 3. Investment Valuation and Fair Value Measurements The Funds’ investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Adviser, subject to oversight of the Board. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. U.S. GAAP establishes the three-tier hierarchy which is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect management’s assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels. Level 1 – Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities. Level 2 – Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.). Level 3 – Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments). A description of the valuation techniques applied to the Funds’ major classifications of assets and liabilities measured at fair value follows: Prices of fixed-income securities are generally provided by pricing services approved by the Adviser, which is subject to review by the Adviser and oversight of the Board. Pricing services establish a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. In pricing certain securities, particularly less liquid and lower quality securities, pricing services may consider information about a security, its issuer or market activity provided by the Adviser. These securities are generally classified as Level 2. For any portfolio security or derivative for which market quotations are not readily available or for which the Adviser deems the valuations derived using the valuation procedures described above not to reflect fair value, the Adviser will determine a fair value in good faith using alternative procedures approved by the Adviser, subject to the oversight of the Board. As a general principle, the fair value of a security is the amount that

30 Notes to Financial Statements (continued) the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. To the extent the inputs are observable and timely, the values would be classified as Level 2; otherwise they would be classified as Level 3. The following table summarizes the market value of the Funds’ investments as of the end of the current fiscal period, based on the inputs used to value them: 4. Portfolio Securities Inverse Floating Rate Securities: Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond (referred to as an “Underlying Bond”), typically with a fixed interest rate, into a special purpose tender option bond (“TOB”) trust (referred to as the “TOB Trust”) created by or at the direction of one or more Funds. In turn, the TOB Trust issues (a) floating rate certificates (referred to as “Floaters”), in face amounts equal to some fraction of the Underlying Bond’s par amount or market value, and (b) an inverse floating rate certificate (referred to as an “Inverse Floater”) that represents all remaining or residual interest in the TOB Trust. Floaters typically pay short-term tax-exempt interest rates to third parties who are also provided a right to tender their certificate and receive its par value, which may be paid from the proceeds of a remarketing of the Floaters, by a loan to the TOB Trust from a third party liquidity provider (“Liquidity Provider”), or by the sale of assets from the TOB Trust. The Inverse Floater is issued to a long term investor, such as one or more of the Funds. The income received by the Inverse Floater holder varies inversely with the short-term rate paid to holders of the Floaters, and in most circumstances the Inverse Floater holder bears substantially all of the Underlying Bond’s downside investment risk and also benefits disproportionately from any potential appreciation of the Underlying Bond’s value. The value of an Inverse Floater will be more volatile than that of the Underlying Bond because the interest rate is dependent on not only the fixed coupon rate of the Underlying Bond but also on the short-term interest paid on the Floaters, and because the Inverse Floater essentially bears the risk of loss (and possible gain) of the greater face value of the Underlying Bond. The Inverse Floater held by a Fund gives the Fund the right to (a) cause the holders of the Floaters to tender their certificates at par (or slightly more than par in certain circumstances), and (b) have the trustee of the TOB Trust (the “Trustee”) transfer the Underlying Bond held by the TOB Trust to the Fund, thereby collapsing the TOB Trust. The Fund may acquire an Inverse Floater in a transaction where it (a) transfers an Underlying Bond that it owns to a TOB Trust created by a third party or (b) transfers an Underlying Bond that it owns, or that it has purchased in a secondary market transaction for the purpose of creating an Inverse Floater, to a TOB Trust created at its direction, and in return receives the Inverse Floater of the TOB Trust (referred to as a “self-deposited Inverse Floater”). A Fund may also purchase an Inverse Floater in a secondary market transaction from a third party creator of the TOB Trust without first owning the Underlying Bond (referred to as an “externally-deposited Inverse Floater”). An investment in a self-deposited Inverse Floater is accounted for as a “financing” transaction (i.e., a secured borrowing). For a self-deposited Inverse Floater, the Underlying Bond deposited into the TOB Trust is identified in the Fund’s Portfolio of Investments as “(UB) – Underlying bond of an inverse floating rate trust reflected as a financing transaction,” with the Fund recognizing as liabilities, labeled “Floating rate obligations” on the Statement of Assets and Liabilities, (a) the liquidation value of Floaters issued by the TOB Trust, and (b) the amount of any borrowings by the TOB Trust from a Liquidity Provider to enable the TOB Trust to purchase outstanding Floaters in lieu of a remarketing. In addition, the Fund recognizes in “Investment Income” the entire earnings of the Underlying Bond, and recognizes (a) the interest paid to the holders of the Floaters or on the TOB Trust’s borrowings, and (b) other expenses related to remarketing, administration, trustee, liquidity and other services to a TOB Trust, as a component of “Interest expense” on the Statement of Operations. Earnings due from the Underlying Bond and interest due to the holders of the Floaters as of the end of the current fiscal period are recognized as components of “Receivable for interest” and “Payable for interest” on the Statement of Assets and Liabilities, respectively. In contrast, an investment in an externally-deposited Inverse Floater is accounted for as a purchase of the Inverse Floater and is identified in the Fund’s Portfolio of Investments as “(IF) – Inverse floating rate investment.” For an externally-deposited Inverse Floater, a Fund’s Statement of Assets and Liabilities recognizes the Inverse Floater and not the Underlying Bond as an asset, and the Fund does not recognize the Floaters, or any related borrowings from a Liquidity Provider, as a liability. Additionally, the Fund reflects in “Investment Income” only the net amount of earnings on the Inverse Floater (net of the interest paid to the holders of the Floaters or the Liquidity Provider as lender, and the expenses of the Trust), and does not show the amount of that interest paid or the expenses of the TOB Trust as described above as interest expense on the Statement of Operations.

31 Fees paid upon the creation of a TOB Trust for self-deposited Inverse Floaters and externally-deposited Inverse Floaters are recognized as part of the cost basis of the Inverse Floater and are capitalized over the term of the TOB Trust. During the current fiscal period, the Funds did not have any transactions in self-deposited Inverse Floaters and/or externally-deposited Inverse Floaters. Zero Coupon Securities: A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically. Purchases and Sales: Long-term purchases and sales during the current fiscal period were as follows: The Funds may purchase securities on a when-issued or delayed-delivery basis. Securities purchased on a when-issued or delayed-delivery basis may have extended settlement periods; interest income is not accrued until settlement date. Any securities so purchased are subject to market fluctuation during this period. If a Fund has outstanding when-issued/delayed-delivery purchases commitments as of the end of the current fiscal period, such amounts are recognized on the Statement of Assets and Liabilities. 5. Derivative Investments Each Fund is authorized to invest in certain derivative instruments. As defined by U.S. GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variables. Investments in derivatives as of the end of and/or during the current fiscal period, if any, are included within the Statement of Assets and Liabilities and the Statement of Operations, respectively. Market and Counterparty Credit Risk: In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities. Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount. 6. Fund Shares Common Shares Equity Shelf Programs and Offering Costs: NXC has filed a registration statement with the Securities and Exchange Commission (“SEC”) authorizing the Fund to issue additional common shares through one or more equity shelf programs (“Shelf Offering”), which became effective with the SEC during a prior fiscal period. Under this Shelf Offering, the Fund, subject to market conditions, may raise additional equity capital by issuing additional common shares from time to time in varying amounts and by different offering methods at a net price at or above the Fund’s NAV per common share. In the event the Fund’s Shelf Offering registration statement is no longer current, the Fund may not issue additional common shares until a post-effective amendment to the registration statement has been filed with the SEC. Additional authorized common shares, common shares sold and offering proceeds, net of offering costs under the Fund’s Shelf Offering during the Fund’s current and prior fiscal period were as follows: Fund Non-U.S. Government Purchases Non-U.S. Government Sales and Maturities NXC $ 3,359,026 $ 7,772,903 NXN 1,821,077 1,410,000

32 Notes to Financial Statements (continued) Costs incurred by the Funds in connection with their initial shelf registrations are recorded as a prepaid expense and recognized as “Deferred offering costs” on the Statement of Assets and Liabilities. These costs are amortized pro rata as common shares are sold and are recognized as a component of “Proceeds from shelf offering, net of offering costs” on the Statement of Changes in Net Assets. Any deferred offering costs remaining after the effectiveness of the initial shelf registration will be expensed. Costs incurred by the Funds to keep the shelf registration current are expensed as incurred and recognized as a component of “Other expenses” on the Statement of Operations. Common Share Transactions: Transactions in common shares for the Funds during the Funds’ current and prior fiscal period, where applicable, were as follows: 7. Income Tax Information Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Each Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular federal and designated state income taxes, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation. Each Fund files income tax returns in U.S. federal and applicable state and local jurisdictions. A Fund's federal income tax returns are generally subject to examination for a period of three fiscal years after being filed. State and local tax returns may be subject to examination for an additional period of time depending on the jurisdiction. Management has analyzed each Fund's tax positions taken for all open tax years and has concluded that no provision for income tax is required in the Fund's financial statements. As of the end of the reporting period, the aggregate cost and the net unrealized appreciation/(depreciation) of all investments for federal income tax purposes were as follows: For purposes of this disclosure, tax cost generally includes the cost of portfolio investments as well as up-front fees or premiums exchanged on derivatives and any amounts unrealized for income statement reporting but realized income and/or capital gains for tax reporting, if applicable. As of prior fiscal period end, the components of accumulated earnings on a tax basis were as follows: NXC Six Month Ended 8/31/25 Year Ended 2/28/25 Additional authorized common shares 1,300,000 1,300,000 Common shares sold 41,092 49,308 Offering proceeds, net of offering costs $527,441 $683,280 NXC Six Months Ended 8/31/25 Year Ended 2/28/25 Common Shares: Sold through shelf offering 41,092 49,308 Issued to shareholders due to reinvestment of distributions 747 602 Total 41,839 49,910 Weighted average common share: Premium to NAV per shelf offering common share sold 0.16% 0.21% Fund Tax Cost Gross Unrealized Appreciation Gross Unrealized (Depreciation) Net Unrealized Appreciation (Depreciation) NXC $ 85,708,192 $ 1,663,940 $ (4,935,688) $ (3,271,748) NXN 47,609,360 279,417 (2,333,644) (2,054,227)

33 As of prior fiscal period end, the Funds had capital loss carryforwards, which will not expire: 8. Management Fees and Other Transactions with Affiliates Management Fees: Each Fund’s management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Sub-Adviser is compensated for its services to the Funds from the management fees paid to the Adviser. Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within each individual Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables Fund shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser. The annual fund-level fee, payable monthly, for each fund is calculated according to the following schedule: The annual complex-level fee, payable monthly, for each Fund is calculated according to the following schedule: * The complex-level fee is calculated based upon the aggregate daily “eligible assets” of all Nuveen-branded closed-end funds and Nuveen branded open-end funds (“Nuveen Mutual Funds”). Except as described below, eligible assets include the assets of all Nuveen-branded closed-end funds and Nuveen Mutual Funds organized in the United States. Eligible assets do not include the net assets of: Nuveen fund-of-funds, Nuveen money market funds, Nuveen index funds, Nuveen Large Cap Responsible Equity Fund or Nuveen Life Large Cap Responsible Equity Fund. In addition, eligible assets include a fixed percentage of the aggregate net assets of the active equity and fixed income Nuveen Mutual Funds advised by the Adviser’s affiliate, Teachers Advisors, LLC (except those identified above). The fixed percentage will increase annually until May 1, 2033, at which time eligible assets will include all of the aggregate net assets of the active equity and fixed income Nuveen Mutual Funds advised by Teachers Advisors, LLC (except those identified above). Eligible assets include closed-end fund assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes the closed-end funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining eligible assets in certain circumstances. As of the end of the current fiscal period, the complex-level fee rate for each Fund was as follows: Fund Undistributed Tax-Exempt Income 1 Undistributed Ordinary Income Undistributed Long-Term Capital Gains Unrealized Appreciation (Depreciation) Capital Loss Carryforwards Late-Year Loss Deferrals Other Book-to-Tax Differences Total NXC $ 256,741 $ — $ — $ 1,339,088 $ (2,185,083) $ — $ (291,754) $ (881,008) NXN 209,254 — — 326,550 (4,575,030) — (164,846) (4,204,072) 1 Undistributed tax-exempt income (on a tax basis) has not been reduced for the dividend declared on February 3, 2025 and paid on March 3, 2025.

34 Notes to Financial Statements (continued) Other Transactions with Affiliates: Each Fund is permitted to purchase or sell securities from or to certain other funds or accounts managed by the Sub-Adviser or by an affiliate of the Adviser (each an, “Affiliated Entity”) under specified conditions outlined in procedures adopted by the Board ("cross-trade"). These procedures have been designed to ensure that any cross-trade of securities by the Fund from or to an Affiliated Entity by virtue of having a common investment adviser (or affiliated investment adviser), common officer and/or common trustee complies with Rule 17a-7 under the 1940 Act. These transactions are effected at the current market price (as provided by an independent pricing service) without incurring broker commissions. During the current fiscal period, the Funds did not engage in cross-trades pursuant to these procedures. 9. Borrowing Arrangements Line of Credit: The Funds, along with certain funds managed by the Adviser or by an affiliate of the Adviser (“Participating Funds”), have established a 364-day, $2.7 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for temporary purposes (other than on-going leveraging for investment purposes). Each Participating Fund is allocated a designated proportion of the facility’s capacity (and its associated costs, as described below) based upon a multi-factor assessment of the likelihood and frequency of its need to draw on the facility, the size of the Fund and its anticipated draws, and the potential importance of such draws to the operations and well-being of the Fund, relative to those of the other Funds. A Fund may effect draws on the facility in excess of its designated capacity if and to the extent that other Participating Funds have undrawn capacity. The credit facility expires in June 2026, unless extended or renewed. The credit facility has the following terms: 0.15% per annum on unused commitment amounts and a drawn interest rate equal to the higher of (a) OBFR (Overnight Bank Funding Rate) plus 1.20% per annum or (b) the Fed Funds Effective Rate plus 1.20% per annum on amounts borrowed. Interest expense incurred by the Participating Funds, when applicable, is recognized as a component of “Interest expense and amortization of offering costs” on the Statement of Operations. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Interest expense” on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund. During the current fiscal period, the Funds did not utilize this facility. 10. Inter-Fund Borrowing and Lending Inter-Fund Borrowing and Lending: The SEC has granted an exemptive order permitting registered open-end and closed-end Nuveen funds to participate in an inter-fund lending facility whereby the Nuveen funds may directly lend to and borrow money from each other for temporary purposes (e.g., to satisfy redemption requests or when a sale of securities “fails,” resulting in an unanticipated cash shortfall) (the “Inter-Fund Program”). The closed-end Nuveen funds, including the Funds covered by this shareholder report, will participate only as lenders, and not as borrowers, in the Inter-Fund Program because such closed-end funds rarely, if ever, need to borrow cash to meet redemptions. The Inter-Fund Program is subject to a number of conditions, including, among other things, the requirements that (1) no fund may borrow or lend money through the Inter-Fund Program unless it receives a more favorable interest rate than is typically available from a bank or other financial institution for a comparable transaction; (2) no fund may borrow on an unsecured basis through the Inter-Fund Program unless the fund’s outstanding borrowings from all sources immediately after the inter-fund borrowing total 10% or less of its total assets; provided that if the borrowing fund has a secured borrowing outstanding from any other lender, including but not limited to another fund, the inter-fund loan must be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value; (3) if a fund’s total outstanding borrowings immediately after an inter-fund borrowing would be greater than 10% of its total assets, the fund may borrow through the inter-fund loan on a secured basis only; (4) no fund may lend money if the loan would cause its aggregate outstanding loans through the Inter-Fund Program to exceed 15% of its net assets at the time of the loan; (5) a fund’s inter-fund loans to any one fund shall not exceed 5% of the lending fund’s net assets; (6) the duration of inter- fund loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days; and (7) each inter-fund loan may be called on one business day’s notice by a lending fund and may be repaid on any day by a borrowing fund. In addition, a Nuveen fund may participate in the Inter-Fund Program only if and to the extent that such participation is consistent with the fund’s investment objective and investment policies. The Board is responsible for overseeing the Inter-Fund Program. The limitations detailed above and the other conditions of the SEC exemptive order permitting the Inter-Fund Program are designed to minimize the risks associated with Inter-Fund Program for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. When a fund borrows money from another fund, there is a risk that the loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at a higher rate or take other actions to payoff such loan if an inter-fund loan is not available from another fund. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs. During the current fiscal period, none of the Funds covered by this shareholder report have entered into any inter-fund loan activity.

35 Additional Fund Information (U naudited) Portfolio of Investments Information Each Fund is required to file its complete schedule of portfolio holdings with the Securities and Exchange Commission (SEC) for the first and third quarters of each fiscal year as an exhibit to its report on Form N-PORT.

36 Glossary of Terms Used in this Report (U naudited) Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or offer price and reinvested dividends and capital gains distributions, if any) over the time period being considered. Effective Leverage: Effective leverage is a fund’s effective economic leverage, and includes both regulatory leverage (see leverage) and the leverage effects of certain derivative investments in the fund’s portfolio. Currently, the leverage effects of Tender Option Bond (TOB) inverse floater holdings are included in effective leverage values, in addition to any regulatory leverage. Inverse Floating Rate Securities: Inverse floating rate securities are the residual interest in a tender option bond (TOB) trust, sometimes referred to as “inverse floaters”, are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond’s par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an “inverse floater”) to an investor (such as a Fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates’ holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond’s downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond’s value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis. Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash, accrued earnings and receivables) less its total liabilities. NAV per share is equal to the fund’s Net Assets divided by its number of shares outstanding. Pre-Refunded Bond/Pre-Refunding: Pre-Refunded Bond/Pre-Refunding, also known as advanced refundings or refinancings, is a procedure used by state and local governments to refinance municipal bonds to lower interest expenses. The issuer sells new bonds with a lower yield and uses the proceeds to buy U.S. Treasury securities, the interest from which is used to make payments on the higher-yielding bonds. Because of this collateral, pre-refunding generally raises a bond’s credit rating and thus its value. Tax Obligation/General Bonds: Bonds backed by the general revenues of an issuer, including taxes, where the issuer has the ability to increase taxes by an unlimited amount to pay the bonds back. Tax Obligation/Limited Bonds: Bonds backed by the general revenues of an issuer, including taxes, where the issuer doesn’t have the ability to increase taxes by an unlimited amount to pay the bonds back. Total Investment Exposure: Total investment exposure is a fund’s assets managed by the Adviser that are attributable to financial leverage. For these purposes, financial leverage includes a fund’s use of preferred stock and borrowings and investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities.

Statement Regarding Basis for Approval of Investment Advisory Contract 37 (U naudited) Nuveen California Select Tax-Free Income Portfolio Nuveen New York Select Tax-Free Income Portfolio The Approval Process At meetings held on April 28 and 29, 2025 (the “Meeting”), the Boards of Directors or Trustees (as the case may be) of the group of funds advised by Nuveen Fund Advisors, LLC (“NFAL” or the “Adviser”), including the Funds (as defined below), and the group of funds advised by Teachers Advisors, LLC (“TAL” and all such funds, collectively, the “Nuveen funds” or the “funds”) approved the renewal of the investment management agreements (each, an “Investment Management Agreement”) with NFAL and TAL, respectively. TAL and NFAL are affiliates as NFAL is a subsidiary of Nuveen, LLC, the investment arm of Teachers Insurance and Annuity Association of America (“TIAA”), and TAL is an indirect wholly owned subsidiary of TIAA. The Boards of Trustees of the Funds also approved the renewal of the sub-advisory agreements (each, a “Sub-Advisory Agreement”) with Nuveen Asset Management, LLC (the “Sub-Adviser”). The Sub-Adviser is also an affiliate of the Adviser. The Boards of Directors or Trustees of the Nuveen funds are each a “Board” or collectively the “Board” (as the context may dictate) and the directors or trustees (as the case may be) are each a “Board Member.” The Board Members of each Board are not “interested persons” (as defined under the Investment Company Act of 1940 (the “1940 Act”)) and, therefore, each Board is deemed to be comprised of all disinterested Board Members. References to a Board and the Board Members are interchangeable. In accordance with applicable law, following up to an initial two-year period, the Board of each Fund considers the renewal of each Investment Management Agreement and Sub-Advisory Agreement on behalf of the Fund on an annual basis. The Investment Management Agreements and Sub-Advisory Agreements are collectively referred to as the “Advisory Agreements,” and the Adviser and the Sub-Adviser are collectively the “Fund Advisers” and each a “Fund Adviser.” Below is a summary of the annual review process the Board undertook related to its most recent renewal of the Advisory Agreements with respect to each Nuveen fund covered by this report (each, a “Fund” and, collectively, the “Funds”). To reach their determination, the Board Members considered the review of the Advisory Agreements to be an ongoing process. The Board Members employed the accumulated information, knowledge and experience they had gained during their tenure as disinterested Board Members on the respective Board of the Nuveen funds and its committees in overseeing the applicable funds and working with the respective investment advisers and sub-advisers in their review of the advisory agreements for the fund complex. The Board and/or its committees meet regularly throughout the year and at these meetings, the Board Members received materials and discussed information covering a wide range of topics pertinent to the annual consideration of the renewal of the Advisory Agreements. Such topics include, but are not limited to, the investment performance of the funds over various periods; investment oversight matters; economic, market and regulatory developments; any significant organizational or other developments impacting a Fund Adviser and its strategic plans for its business; product initiatives for various funds; fund expenses; compliance, regulatory and risk management matters; trading practices; the derivatives risk management program; management of distributions; valuation of securities; payments to financial intermediaries; securities lending (as applicable); and closed-end fund market activity, capital management initiatives, institutional ownership, management of leverage financing, the secondary market trading of the closed-end funds and any actions taken to address market discounts to net asset value. The Board also seeks to meet at its regular quarterly meetings with members of senior management to discuss various topics, including market conditions, industry developments and any significant developments or strategic plans for the Fund Advisers, if any. To help with the review of performance, the Board and/or its committees periodically received and discussed presentations from member(s) of investment teams throughout the year, culminating in an annual performance review of the Nuveen funds at the Board’s meeting held on February 25-26, 2025 (the “February Meeting”). The presentations, discussions and meetings during the year provide a means for the Board Members to evaluate and consider the level, breadth and quality of services provided by the Fund Advisers and any changes to such services over time in light of new or modified regulatory requirements, changes to market conditions or other factors. In addition to the materials and discussions that occurred at prior meetings, the Board, through its independent legal counsel, requested and received extensive materials and information prepared specifically for its review of the Advisory Agreements. During the year, management worked with an ad hoc committee established by the Board to help enhance and streamline the materials provided in connection with the annual review of the Advisory Agreements. The materials provided at the Meeting and/or prior meetings covered a wide range of matters including, but not limited to, a description of the nature, extent and quality of services provided by the Fund Advisers; a review of the Sub-Adviser and applicable investment team; an analysis of fund performance with a focus on funds considered to have met certain challenged performance measurements; an analysis of the fees and expense ratios of the Nuveen funds with a focus on funds considered to have certain expense characteristics; a list of management fee and sub-advisory fee schedules; an analysis of advisory fees compared to fees assessed to other types of clients; a description of portfolio manager compensation; certain profitability and/or financial data; and a description of indirect benefits received by the Fund Advisers as a result of their relationships with the Nuveen funds. The Board also considered information provided by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data, comparing fee and expense levels of each respective Fund to those of a peer universe. The information prepared specifically for the annual review supplemented the information provided to the Board and its committees and the evaluations of the Nuveen funds by the Board and its committees during the year. The Board’s review of the Advisory Agreements is based on all the information provided to the Board and its committees over time. The performance, fee and expense data and other information provided by a Fund Adviser, Broadridge or other service providers were not independently verified by the Board Members. As part of their review, the Board Members and independent legal counsel met in executive session on April 9, 2025 to review and discuss materials provided in connection with their annual review of the Advisory Agreements. After reviewing this information, the Board Members requested, directly or through independent legal counsel, additional information, and the Board subsequently reviewed and discussed the responses to these follow-up questions and requests. The Board Members and independent legal counsel met again in executive session on April 17, 2025 (together

38 Statement Regarding Basis for Approval of Investment Advisory Contract (continued) with the April 9, 2025 executive session, the “Executive Sessions”) to discuss the responses to the initial supplemental information request and, following their review of the data provided, requested management present certain additional information at the Meeting. In addition to the Executive Sessions, the Board Members met in additional executive sessions prior to and during the Meeting. During the Meeting, the Board Members considered the responses, invited representatives of management to provide additional information and determined that the information provided (whether oral or written) was responsive to their requests. The Board Members were advised by independent legal counsel during the annual review process as well as throughout the year, including meeting in executive sessions with such counsel at which no representatives of management were present. In connection with their annual review, the Board Members also received a memorandum from independent legal counsel outlining their fiduciary duties and legal standards in reviewing the Advisory Agreements, including guidance from court cases evaluating advisory fees. After the discussions and with the background and knowledge described above, the Board Members approved the continuation of the Advisory Agreements on behalf of the applicable Funds for an additional one-year period. The Board did not identify any single factor as all-important or controlling, but rather each decision reflected the comprehensive consideration of all the information (written or oral) provided to the Board and its committees throughout the year as well as the materials prepared specifically in connection with the annual review process. The contractual arrangements may reflect the results of prior year(s) of review, negotiation and information provided in connection with the Board’s annual review of the Funds’ advisory arrangements and oversight of the Funds. Each Board Member may have attributed different levels of importance to the various factors and information considered in connection with the annual review process and may have placed different emphasis on the relevant information year to year in light of, among other things, changing market and economic conditions. A summary of the principal factors and information, but not all the factors, the Board considered in deciding to renew the Advisory Agreements is set forth below. A. Nature, Extent and Quality of Services In evaluating the renewal of the Advisory Agreements, the Board Members received and considered information regarding the nature, extent and quality of the applicable Fund Adviser’s services provided to each respective Fund. With this approach, they considered the roles of the Adviser and the Sub-Adviser in providing services to the Funds. The Board considered that the Adviser provides a wide array of management, oversight and other services to manage and operate the Funds. The Board considered the Adviser and its affiliates’ dedication of resources, time, people and capital as well as consistent program of improvement and innovation aimed at keeping the Nuveen fund complex relevant and attractive for existing and new investors and meeting the needs of an increasingly complex regulatory environment. Among the information provided in connection with the review of services at the Meeting and/or prior meetings, the Board considered a description of the organizational changes at the Adviser during the year, the management teams that comprise the various support and investment functions for the funds and the background of certain personnel who support the funds. The Board considered the significant resources, both financial and personnel, the Adviser and its affiliates had committed over the past several years in working to bring the asset management businesses of Nuveen and TIAA under one centralized umbrella and to consolidate their respective fund families to the benefit of the funds through, among other things, enhanced operating efficiencies, centralized investment leadership and a centralized shared resources and support model. To help ensure the continuation of services, the Board considered, among other things, management’s emphasis on succession planning and key person risk evaluation pursuant to which certain management team(s) meet annually to conduct a comprehensive review of successors to key positions, to develop and monitor corporate-wide standards and procedures in seeking to help ensure the firm may continue to operate in the event of business disruptions, and to review staffing and compensation levels to help remain competitive with peers in the industry. The Board considered a description of the application of business continuity plans and the periodic testing and review of such plans. As noted below, the Board also considered certain financial data of the Adviser and TIAA in assessing the financial stability and condition of the Adviser to provide a high level of quality of services to the Funds. In its review, the Board considered that the Funds operated in a highly regulated industry and the scope and complexity of the services and resources that the Adviser and its affiliates must provide to manage and operate the Funds have expanded over the years due to regulatory, market and other developments. Such services included maintaining and monitoring the Nuveen funds’ compliance programs, risk management programs, liquidity risk management programs, derivatives risk management programs and cybersecurity programs. The Board and/or its Compliance, Risk Management and Regulatory Oversight Committee received reports regarding the funds’ compliance policies and procedures and matters undertaken thereunder as well as other compliance initiatives on a regular basis. In considering the breadth and quality of services the Adviser and its various teams provide, the Board considered that the Adviser provides investment advisory services. With respect to the Funds, such Funds utilize the Sub-Adviser to manage the portfolios of the Funds subject to the supervision of the Adviser. Accordingly, the Board considered that the Adviser and its affiliates, among other things, oversee and review the performance of the Sub-Adviser and its investment team(s); evaluate Fund performance and market conditions; evaluate investment strategies and recommend changes thereto; oversee trade execution and, as applicable, securities lending; evaluate investment risks; and manage valuation matters. As noted below, the Board also considered the Nuveen funds’ performance over various time periods throughout the year. In addition to the portfolio management services provided to the Funds (including indirectly by overseeing the Sub-Adviser), the Board considered the extensive compliance, regulatory, administrative and other services the Adviser and its various teams or affiliates provide to manage and operate the applicable funds, including but not limited to: distribution management services pursuant to which management seeks to implement distribution policies and set distribution levels consistent with each fund’s product design and positioning; compliance services including establishing and maintaining broad-based compliance policies across the Nuveen fund complex, evaluating the compliance programs of various fund services providers, conducting ongoing risk assessments and testing, monitoring portfolio compliance with investment and regulatory requirements and providing a comprehensive compliance training program; providing regulatory advocacy services, including submitting comments on regulatory proposals and monitoring regulatory developments that may impact the fund(s); providing support to the Board and its committees throughout the year, including providing reports on a wide range of topics relating to the operations and management of the funds, helping to refine the materials

39 provided to the Board and/or its committees and providing educational sessions on various topics; establishing and reviewing the services provided by other fund service providers (such as a fund’s custodian, accountant, and transfer agent); providing legal support services; and evaluating trade allocation and execution. Such services also include managing leverage; providing capital management and secondary market services (such as implementing common share shelf offerings, capital return programs and common share repurchases); and maintaining a closed-end fund investor relations program. The Board considered that management actively monitors any discount from net asset value per share at which a fund’s common stock trades and evaluates potential avenues to mitigate the discount, including evaluating the level of distributions that the fund pays. Aside from the services provided, the Board considered the financial resources of the Adviser and/or its affiliates and their willingness to make investments to support the funds. The Board considered the funds’ access to a seed capital budget provided by the Adviser and/or its affiliates to support new or existing funds and/or facilitate changes for a respective fund. The Board considered the benefits to shareholders of investing in a Fund that is a part of a large fund complex with a variety of investment disciplines, capabilities, and expertise. The Board considered the overall reputation and capabilities of the Adviser and its affiliates and the Adviser’s continuing commitment to provide high quality services. In its review, the Board also considered the significant risks borne by the Adviser and its affiliates in connection with their services to the Nuveen funds, including entrepreneurial risks in sponsoring and supporting new funds and smaller funds and ongoing risks with managing the Funds, such as investment, operational, reputational, regulatory, compliance and litigation risks. The Board considered the division of responsibilities between the Adviser and the Sub-Adviser and considered that the Sub-Adviser and its investment personnel, as noted, generally are responsible for the management of the respective Fund’s portfolio under the oversight of the Adviser and the Board. The Board considered an analysis of the Sub-Adviser provided by the Adviser which included, among other things, a summary of changes (if any) in the leadership teams and/or portfolio manager teams; the performance of the funds sub-advised by the Sub-Adviser over various periods of time that met certain performance screening measurements; and data reflecting product changes (if any) taken with respect to certain funds. The Board considered that the Adviser recommended the renewal of the Sub-Advisory Agreements. Based on its review, the Board determined, in the exercise of its reasonable business judgment, that it was satisfied with the nature, extent and quality of services provided to the respective Funds under each applicable Advisory Agreement. B. The Investment Performance of the Funds and Fund Advisers In evaluating the quality of the services provided by the Fund Advisers, the Board also considered a variety of investment performance data of the Funds. In leading up to the annual review, the Board and/or its Investment Committee considered, among other things, Fund performance (based on net asset value net of fees) over the quarter, one-, three- and five-year periods ending December 31, 2024 on an absolute basis and as compared to the performance of comparable peers (the “Performance Peer Group”) and to a benchmark for the prescribed periods. Prior to the Meeting, the Board also received updated Fund performance over the quarter, one-, three- and five-year periods ended March 31, 2025 on an absolute basis and in comparison to the Performance Peer Group and a benchmark for the prescribed periods. In its review of relative performance, the Board considered a Fund’s performance relative to its Performance Peer Group, among other things, by evaluating its quartile ranking with the 1st quartile representing the top performing funds within the Performance Peer Group and the 4th quartile representing the lowest performing funds. The Board took into account the performance data, presentations and discussions (written and oral) that were provided at the Meeting and in prior meetings over time in evaluating fund performance, including particular focus on management’s analysis of the performance of funds that met certain screening measurements as determined pursuant to a methodology approved by the Board or additional measurements as determined by management’s investment analysts. As various Nuveen funds have modified their portfolio teams and/or made significant changes to their portfolio strategies over time, the Board reviewed, among other things, certain tracking performance data over specific periods comparing performance before and after such changes. In evaluating performance, the Board considered some of the limitations of the performance data. The Board considered, among other things, that performance data reflects performance over a specified period which may differ significantly depending on the ending dates selected, particularly during periods of market volatility. Further, the Board considered that regardless of the performance period reviewed by the Board, shareholders may evaluate performance based on their own respective holding periods which may differ from the performance periods reviewed by the Board and lead to differing results. With respect to comparative performance, the Board considered that differing investment objectives, investment strategies, dates of inception, type and cost of leverage (if any), asset size and other factors between the Performance Peer Group and the respective Fund necessarily lead to differences in performance results. Similarly, differences in the investment objective(s) and strategies of a Fund and its benchmark (particularly an actively managed fund that does not directly follow an index) as well as the costs of operating a Fund would contribute to differences in performance results. To assist the Board in its review of the comparability of the relative performance, management generally has ranked the relevancy of the Performance Peer Groups to the applicable funds (subject to certain exceptions) as low, medium or high. The Board also considered that secondary market trading of shares of the closed-end funds also continues to be a priority for the Board given its importance to shareholders, and therefore, the Board and/or its Closed-End Fund Committee reviews certain performance data reflecting, among other things, the premiums and discounts at which the shares of the closed-end funds have traded as of specified dates at their quarterly meetings with an annual review of the closed-end fund market for the 2024 calendar year at its February Meeting. In its review, the Board considered, among other things, market conditions for closed-end funds, changes to investment mandates and guidelines, distribution policies, and leverage management; additional share offerings, share repurchases (if any) and similar capital market actions; and effective communications programs to build greater awareness and deepen understanding of closed-end funds. As applicable, the Board considered, among other things, the impact of leverage on a closed-end fund’s common share earnings and total return.

40 Statement Regarding Basis for Approval of Investment Advisory Contract (continued) The Board evaluated performance in light of various relevant factors which may include, among other things, general market conditions, issuer- specific information, asset class information, leverage and fund cash flows. The Board considered that long-term performance could be impacted by even one period of significant outperformance or underperformance and that a single investment theme could disproportionately affect performance. Further, the Board considered that market and economic conditions may significantly impact a Fund’s performance, particularly over shorter periods, and such performance may be more reflective of such economic or market events and not necessarily reflective of management skill. Although the Board reviews short-, intermediate- and longer-term performance data, the Board considered that longer periods of performance may reflect full market cycles. In their review from year to year, the Board Members consider and may place different emphasis on the relevant information in light of changing circumstances in market and economic conditions. In evaluating performance, the Board focused particular attention on funds with less favorable performance records. However, depending on the facts and circumstances, including any differences between the respective fund and its benchmark and/or Performance Peer Group, the Board may be satisfied with a fund’s performance notwithstanding that its performance may be below that of its benchmark and/or peer group for certain periods. With respect to any funds for which the Board has identified performance issues, the Board seeks to monitor such funds more closely until performance improves, discuss with the Adviser the reasons for such results, consider whether any steps are necessary or appropriate to address such issues, discuss and evaluate the potential consequences of such steps and review the results of any steps undertaken. The performance determinations with respect to each Fund are summarized below: For Nuveen California Select Tax-Free Income Portfolio, the Board considered that although the Fund’s performance was below the performance of its benchmark for the three-year period ended December 31, 2024, the Fund outperformed its benchmark for the one-year period ended December 31, 2024 and matched the performance of its benchmark for the five-year period ended December 31, 2024. In addition, the Fund ranked in the second quartile of its Performance Peer Group for the one-year period and first quartile for the three- and five-year periods ended December 31, 2024. In its review, the Board considered that the Performance Peer Group was classified as low for relevancy. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements. For Nuveen New York Select Tax-Free Income Portfolio, the Board considered that although the Fund’s performance was below the performance of its benchmark for the three- and five-year periods ended December 31, 2024, the Fund outperformed its benchmark for the one-year period ended December 31, 2024. In addition, the Fund ranked in the first quartile of its Performance Peer Group for the one-, three- and five-year periods ended December 31, 2024. In its review, the Board considered that the Performance Peer Group was classified as low for relevancy. On the basis of the Board’s ongoing review of investment performance and all relevant factors, including the relative market conditions during certain reporting periods, the Fund’s investment objective(s) and management’s discussion of performance, the Board concluded that the Fund’s performance supported renewal of the Advisory Agreements. C. Fees, Expenses and Profitability 1. Fees and Expenses As part of the annual review, the Board Members considered, among other things, the management fee schedules for the respective Fund. In addition to the management fee arrangements, the Board Members considered a Fund’s operating expense ratio as it more directly reflected a shareholder’s total costs in investing in the respective Fund. In its review, the Board considered that the management fees of the Funds were generally comprised of two components, a fund-level component and a complex-level component, each with its own breakpoint schedule, subject to certain exceptions. The Board considered that in 2024, the Board approved a revised complex-wide breakpoint schedule which simplified and reduced the complex-level fee rates at various thresholds and expanded the eligible funds whose assets would be included in calculating the complex-level fee, effective May 1, 2024. The Board considered that the complex-level component is intended to be an efficient mechanism designed to help share cost efficiencies with shareholders as the complex-wide assets grow. The Board also considered comparative fee and expense information prepared by an independent third-party provider of fund data. More specifically, the Board Members generally reviewed, among other things, each Fund’s management fee rates and net total expense ratio in relation to similar data for a comparable universe of peers (the “Expense Universe”). In their review, the Board Members considered, in particular, each fund with a net total expense ratio (based on common assets and excluding investment-related costs such as the costs of leverage and taxes) meeting certain expense screening criteria adopted by the Board when compared to its Expense Universe and management’s commentary as to the factors contributing to each such fund’s relative net total expense ratio. The Board also considered, in relevant part, a fund’s management fee in light of its performance history with particular focus on any fund identified as having a higher management fee and/or expense ratio compared to peers coupled with experiencing a period of challenged performance. In their review, the Board Members considered the methodology Broadridge employed to establish its Expense Universe. The Board further considered that differences between the applicable Fund and its Expense Universe, as well as changes to the composition of the Expense Universe from year to year, may limit some of the value of the comparative data. The Board Members also considered that it can be difficult to compare management fees among funds with peers as there are variations in the services that are included for the fees paid. The Board Members took these limitations and differences into account when reviewing comparative peer data.

41 In addition, although the Board reviewed net total expense ratio both including and excluding investment-related expenses (e.g., leverage costs), as applicable, the Board considered that leverage expenses will vary across funds and peers because of differences in the forms and terms of leverage employed by the respective fund and therefore generally considered each closed-end fund’s net total expense ratio and fees excluding investment-related costs and taxes. The Board also considered that the use of leverage may create a conflict of interest for the respective Adviser and Sub-Adviser given the increase of assets from leverage upon which an advisory or sub-advisory fee is based but also considered the impact of leverage on the fund’s return. The Board Members considered, however, that the Adviser and Sub-Adviser would seek to manage the potential conflict by recommending to the Board to leverage the applicable fund or increase such leverage when the respective Fund Adviser has determined that such action would be in the best interests of the respective fund and its common shareholders and by periodically reviewing with the Board the fund’s performance and the impact of the use of leverage on that performance. With respect to the Sub-Adviser, the Board also considered, among other things, the sub-advisory fee schedule paid to the Sub-Adviser in light of the sub-advisory services provided to the respective Fund. In its review, the Board considered that the compensation paid to the Sub-Adviser is the responsibility of the Adviser, not the Funds. The Board’s considerations regarding the comparative fee data for each Fund are set forth below: For Nuveen California Select Tax-Free Income Portfolio, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median. For Nuveen New York Select Tax-Free Income Portfolio, the Fund’s contractual management fee rate, actual management fee rate and net total expense ratio were each below the Expense Universe median. Based on its review of the information provided, the Board determined that each Fund’s management fees (as applicable) to a Fund Adviser were reasonable in light of the nature, extent and quality of services provided to the Fund. 2. Comparisons with the Fees of Other Clients In evaluating the appropriateness of fees, the Board also considered that the Adviser, the Sub-Adviser and/or their affiliate(s) provide investment management services to other types of clients which may include, among others: separately managed accounts (“SMAs”), retail managed accounts, foreign funds (UCITS), other investment companies (as sub-advisers), limited partnerships and collective investment trusts. The Board considered certain fee data for these other types of clients managed in a similar manner to certain of the funds compared to the management fee of the applicable fund. The Board considered a description of various factors which contribute to the differences in the management fee rates of the funds compared to those charged to these other types of clients which limited the comparability of the data. In this regard, the Board considered that the differences in, among other things, the breadth of services provided by the Adviser and its affiliates to the funds compared to those provided to other clients; the expenses the Adviser and its affiliates incur in launching, operating and supporting a fund; the support services provided to shareholders; the extensive regulatory, disclosure and governance requirements applicable to funds; the establishment and maintenance of servicing relationships with various service providers for the funds; the manner of managing such assets; investment policies; investor profiles; and account sizes all may contribute to the variations in relative fee rates. Differences in the level of advisory services required for passively managed funds also contribute to differences in the management fee levels of such funds compared to actively managed funds. In addition, differences in the client base; governing bodies, regulatory and legal requirements; distribution; jurisdiction and operational complexities also would contribute to variations in management fees assessed the funds compared to foreign fund clients. Further, differences in the level of advisory and non-advisory services required and risk incurred when serving as a sub-adviser to other investment companies compared to serving as the Adviser to a Nuveen fund contribute to differences in the fees assessed. In this regard, the Board further considered the significant entrepreneurial, legal and regulatory risks that the Adviser incurs in sponsoring and managing the Funds. As a general matter, higher fee levels reflect higher levels of service provided by the Adviser, increased investment management complexity, greater product management requirements, and higher levels of business risk or some combination of these factors. The Board further considered that the Sub-Adviser’s fee is essentially for portfolio management services and therefore more comparable to the fees received for retail wrap accounts and other external sub-advisory mandates. The Board concluded that the varying levels of fees were reasonable given the foregoing. 3. Profitability of the Fund Advisers In considering the costs of services to be provided and profits to be realized by the Adviser (which encompassed the Sub-Adviser) from its relationship with the Funds, the Board Members considered a variety of estimated profitability data from various perspectives including, among other things, (a) historical pre-distribution and post-distribution margins over specified periods for the Adviser’s services to the applicable funds; (b) certain profitability data on behalf of the Adviser attributable to servicing all applicable funds for 2024 and 2023; (c) certain profitability data of both the Adviser and TAL (as an adviser of certain other Nuveen funds) on a combined basis derived from types of funds in the aggregate (i.e., from closed-end funds, exchange-traded funds, interval funds and open-end funds) for 2024 and 2023; and (d) certain profitability data of both the Adviser and TAL on a combined basis by asset grouping of Nuveen funds in the aggregate (i.e., from equity, fund of funds, index, municipal bond and taxable fixed income funds). In addition, the Board considered profitability data at the per fund level for the respective adviser.

42 Statement Regarding Basis for Approval of Investment Advisory Contract (continued) In reviewing the profitability data, the Board Members considered the subjective nature of calculating profitability as the information is not audited and is necessarily dependent on cost allocation methodologies to allocate expenses throughout the complex and among the various advisory products. The Board reviewed, among other things, a description of the cost allocation methodology employed to develop the profitability data. However, the Board Members considered that given there is no single universally recognized expense allocation methodology, other reasonable and valid allocation methodologies could be employed and could lead to significantly different profit and loss results and therefore developing profitability data is difficult, particularly on a per fund level. Further, in considering the comparative margin data with peers, the Board Members considered the limitations of the comparative data given that peer data is not generally public and the calculation of profitability is subjective and affected by numerous factors (such as types of funds a peer manages, its business mix, its cost of capital, the numerous assumptions underlying the methodology used to allocate expenses and other factors) that can have a significant impact on the results. Given that the peer profitability data may reflect the different business mix of the respective peer firm, the Board also considered the pre- and post-distribution margins of Nuveen, LLC for each of the calendar years from 2020 through 2024. Aside from the foregoing profitability data, the Board also considered, among other things, the audited statutory-basis financial statements of TIAA as of December 31, 2024 and 2023 and the related statutory-basis statements of operations, of changes in capital and contingency reserves and of cash flows for the years ended December 31, 2024, December 31, 2023 and December 31, 2022. The Board considered the benefit of an investment adviser and its parent with significant resources, particularly during periods of market volatility. The Board also considered the investments the Adviser, its parent and/or other affiliates made into their business. In evaluating the reasonableness of the compensation, the Board Members also considered the indirect benefits the Adviser or Sub-Adviser received that were directly attributable to the management of the applicable funds as discussed in further detail below. Based on its review, the Board was satisfied that the Adviser’s (together with the Sub-Adviser) level of profitability from its relationship with the applicable Fund was not unreasonable in light of the nature, extent and quality of services provided. D. Economies of Scale and Whether Fee Levels Reflect These Economies of Scale The Board considered whether there have been economies of scale with respect to the management of the funds, whether these economies of scale have been appropriately shared with the funds and whether there is potential for realization of further economies of scale. Although the Board considered that economies of scale are difficult to measure with any precision and the rates at which certain expenses are incurred may not decline with a rise in assets, the Board considered that there are a variety of methods that may be employed to help share the benefits of economies of scale, including, among other things, through the use of breakpoints in the management fee schedule, the pricing of funds at scale at inception and investments in the Adviser’s business which can enhance the services provided to the funds for the fees paid. The Board considered such factors applicable to the particular Fund’s advisory fee structure. As noted above, the Board considered that the management fee of the Adviser for the Funds generally was comprised of a fund-level component and a complex-level component each with its own breakpoint schedule. The Board also approved a revised complex-wide breakpoint schedule in 2024 which reduced the complex-level fee rates at various thresholds and expanded the assets included when calculating the complex-level fee. With this structure, the Board considered that the complex-level breakpoint schedule was designed to deliver the benefits of economies of scale to shareholders when the assets of the eligible participating funds in the complex pass certain thresholds even if the assets of a particular fund are unchanged or have declined, and the fund-level breakpoint schedules were designed to share economies of scale with shareholders if the particular fund grows. The Board reviewed the fund-level and complex-level fee schedules. Although closed-end funds may make additional share offerings from time to time, the Board considered that closed-end funds have a more limited ability to increase their assets to attain additional economies of scale because the growth of their assets will occur primarily from the appreciation of their investment portfolios. The Board Members also considered the continued reinvestment in Nuveen’s business to enhance its capabilities and services to the benefit of its various clients. The Board considered that many of these investments were not specific to individual Nuveen funds, but rather initiatives from which the family of funds as a whole may benefit. The Board further considered that the scope of the services of the Adviser and its affiliates have expanded over time without raising advisory fees to the funds, and this was also a means of sharing economies of scale with the funds and their shareholders. The Board considered the Adviser’s and/or its affiliates’ ongoing efforts to streamline the product line-up, among other things, to create more scaled funds which may help improve both expense and trading economies for participating funds. Based on its review, the Board was satisfied that the current fee arrangements together with the reinvestment in management’s business appropriately shared any economies of scale with shareholders. E. Indirect Benefits The Board Members received and considered information regarding various indirect benefits the respective Fund Adviser or its affiliates may receive as a result of their relationship with the funds. These benefits included, among other things, economies of scale to the extent the Adviser or its affiliates share investment resources and/or personnel with other clients of the Adviser. Certain funds may also be used as investment options for other products or businesses offered by the Adviser and/or its affiliates, such as variable products, fund of funds and 529 education savings plans, and the Adviser and/or affiliates of the Adviser may serve as sub-adviser to various funds in which case all advisory and sub-advisory fees generated by such funds stay within Nuveen.

43 Further, the funds may pay the Adviser and/or its affiliates for other services, such as distribution. In this regard, the Board considered that an affiliate of the Adviser received compensation in 2024 for serving as an underwriter on shelf offerings of existing closed-end funds and reviewed the amounts paid for such services in 2024 and 2023. In addition, the Board Members considered that the Adviser and Sub-Adviser (except as noted) may utilize soft dollar brokerage arrangements attributable to the respective fund(s) to obtain research and other services for any or all of their clients, although the Board Members also considered with respect to the Nuveen funds advised by the Adviser, reimbursements of such costs by the Adviser and/or the Sub-Adviser. The Adviser and its affiliates may also benefit from the advisory relationships with the Nuveen funds to the extent this relationship results in potential investors viewing the TIAA group of companies as a leading retirement plan provider in the academic and nonprofit market and a single source for all their financial service needs. The Adviser and/or its affiliates may further benefit to the extent that they have pricing or other information regarding vendors the funds utilize in establishing arrangements with such vendors for other products. Based on its review, the Board concluded that any indirect benefits received by a Fund Adviser as a result of its relationship with the Funds were reasonable in light of the services provided. F. Other Considerations The Board Members did not identify any single factor discussed previously as all-important or controlling. The Board Members concluded that the terms of each Advisory Agreement were reasonable, that the respective Fund Adviser’s fees were reasonable in light of the services provided to each Fund and that the Advisory Agreements be renewed for an additional one-year period.
