Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

4 Wells Fargo Money Market Fund Letter to shareholders (unaudited)

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

Don’t let short-term uncertainty derail long-term investment goals.

To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at at the amounts shown. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s 7-day current yield would have been 1.98%, 1.23%, 2.37%, and 2.08% for Class A, Class C, Premier Class, and Service Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Historical performance shown for the Class C shares prior to their inception reflects the performance of the former Class B shares. Class B and Class C shares had the same expenses.

⁴  Historical performance shown for the Premier Class shares prior to their inception reflects the performance of the Class A shares, and includes the higher expenses applicable to Class A shares. If these expenses had not been included, returns for Premier Class shares would be higher.

If these expenses had not been included, returns for Service Class shares would be higher.

⁶  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁷  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁸  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGERS’ DISCUSSION

For most of the reporting period, continued economic improvement allowed the Federal Open Market Committee (FOMC) to remove policy accommodation on a fairly predictable quarterly basis. The U.S. economy achieved above-trend growth, low unemployment, and moderating inflation at the same time as fiscal policy was proving to be an economic tailwind. The FOMC’s Summary of Economic Projections (SEP) through September reflected this scenario and provided the market with some clarity as to the path of future interest rate policy. However, the economic landscape changed in the fourth quarter as the U.S. engaged in various trade wars, the midterm elections disrupted the legislative composition, and financial conditions tightened. These factors began softening economic data and confidence, leading to increased volatility in risk assets. At the conclusion of the FOMC policy meeting on December 19, 2018, the federal funds target rate was raised to a target range of between 2.25% to 2.50% while the rate of interest on excess reserves (IOER) was increased by only 20 basis points (bps; 100 bps equal 1.00%) to 2.40%. That was the second time the IOER rate was increased 5 bps less than the increase in the target rate in an effort to keep the effective federal funds rate from drifting to the upper level of the target range.

In the accompanying SEP, the FOMC provided insight on its view of the economy, inflation, and the corresponding monetary policy expected over the next few years. And the December projections did not disappoint market observers, with the FOMC marginally decreasing its outlook on growth and inflation and correspondingly lowering the glide path for its target rate to 2.875% and decreasing its median outlook for the number of interest rate hikes in 2019 from three to two. Comparing the September and December target rate projections, the longer-term section points to an expectation of the eventual neutral rate being marginally lower at 2.75% and lowered 2020 and 2021 median interest rate expectations at 3.125%. On the growth front, the 2019 median gross domestic product projection edged down 0.2% to 2.3% while 2020 and 2021 growth projections remained unchanged at 2.0% and 1.8%, respectively. Core inflation in the 2019 to 2021 projections all declined 0.1% to 2.0%. The lower expectations for interest rates in the next three years show the FOMC members are less concerned regarding the potential for inflationary pressures and more focused on balancing a somewhat softer economy. In fact, the statement released at the conclusion of the January 2019 FOMC meeting removed the wording of “some further gradual increases,” citing increasing downside risk from abroad, weaker domestic data, and tighter financial conditions.

As the FOMC’s expectations for rate increases moved lower, the market expectations for federal funds rate increases, as measured by federal funds futures, moved even lower still. Market participants are barely pricing in any rate hike in 2019 and may even be starting to prepare for a possible rate cut toward the end of 2019 and into 2020. The U.S. Federal Reserve will have plenty of opportunities to adjust expectations starting in 2019 as Chair Jerome Powell will conduct a press conference after each FOMC meeting instead of only quarterly. On the heels of the FOMC lowering its economic and inflation projections, risk assets underperformed and U.S. equities are teetering near bear-market territory.

The rise in short rates has brought not only attention but perhaps also nontraditional money market investors (those who typically invest in longer-term debt or equities) into the short end of the market. The Crane Prime Institutional Money Market Index, maintained by Crane Data LLC⁹, was up over $61 billion during the period, with all prime assets up over $152 billion. Investors reexamining this product may be realizing that the changes implemented from the 2010 money market reform have made a material difference in the construction of prime money market fund portfolios. The added liquidity requirements and maturity restrictions have had a beneficial impact on dampening net asset value (NAV) volatility even as the FOMC continued to raise rates and credit spreads widened. In addition, added transparency of holdings can provide a daily view of the portfolio construction process and allow shareholders to assess portfolio risks.

Strategic outlook

The FOMC has pivoted from a gradually removing accommodation outlook to a data-dependent stance requiring what it terms as “patience.” Going forward, money market investors should continue to look toward the FOMC and other market indicators for future rate guidance. As we get more clarity as to the end of the tightening cycle, money market participants may look to extend weighted average maturities (WAMs) to capture higher yields. Our strategy of emphasizing highly liquid portfolios, relatively short WAMs, and a position in securities that reset frequently allows us to capture elevated London Interbank Offered Rate levels with minimal NAV pricing pressures and afford the flexibility to add longer-dated securities as opportunities arise.

Fund expenses (unaudited) Wells Fargo Money Market Fund 9

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution (12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Hypothetical (5% return before expenses)	$	1,000.00	$	1,022.69	$	2.55		0.50	%

¹ Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect the one-half-year period).

Notes to financial statements Wells Fargo Money Market Fund 23

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946,Financial Services – Investment Companies. These financial statements report on the Wells Fargo Money Market Fund (the “Fund”) which is a diversified series of the Trust.

Effective at the close of business on July 5, 2017, Class B shares were converted to Class A shares and are no longer offered by the Fund. Information for Class B shares reflected in the financial statements represents activity through July 5, 2017.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

As permitted under Rule 2a-7 of the 1940 Act, portfolio securities are valued at amortized cost, which approximates fair value. The amortized cost method involves valuing a security at its cost, plus accretion of discount or minus amortization of premium over the period until maturity.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that are marked-to-market daily. The collateral may be held by an agent bank under a tri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis are marked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed on non-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed from non-accrual status.

24 Wells Fargo Money Market Fund Notes to financial statements

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the cost of investments for federal income tax purposes is substantially the same as for financial reporting purposes.

Reclassifications are made to the Fund’s capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under federal income tax regulations. U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. The primary permanent difference causing such reclassification is due to expiration of capital loss carryforwards. At January 31, 2019, as a result of permanent book-to-tax differences, the following reclassification adjustments were made on the Statement of Assets and Liabilities:

Paid-in capital	Total distributable loss
$(385,874)	$385,874

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadvisers and providing fund-level administrative services in connection with the Fund’s operations. As compensation for its services under the investment management agreement, Funds Management is entitled to receive an annual management fee starting at 0.20% and declining to 0.18% as the average daily net assets of the Fund increase. Prior to June 1, 2018, Funds Management received a fee at an annual rate which started at 0.35% and declined to 0.23% as the average daily net assets of the Fund increased. For the year ended January 31, 2019, the management fee was equivalent to an annual rate of 0.24% of the Fund’s average daily net assets.

Funds Management has retained the services of certain subadvisers to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase. Wells Capital Management Singapore, a separately identifiable department of Wells Fargo Bank, N.A, an affiliate of Funds Management and wholly owned subsidiary of Wells Fargo, is also a subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.0025% and declining to 0.0005% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent, sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.22	%
Premier Class		0.08
Service Class		0.12

26 Wells Fargo Money Market Fund Notes to financial statements

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.60% for Class A shares, 1.35% for Class C shares, 0.20% for Premier Class shares, and 0.50% for Service Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Prior to June 1, 2018, the Fund’s expenses were capped at 0.65% for Class A shares and 1.40% for Class C shares.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule 12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. No contingent deferred sales charges were incurred by Class C shares for the year ended January 31, 2019.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Service Class, of the Fund are charged a fee at an annual rate of 0.25% of the respective average daily net assets of each class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid was $9,861,868 and $3,274,201 of ordinary income for the years ended January 31, 2019 and January 31, 2018, respectively.

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders under U.S. generally accepted accounting principles. The amounts of distributions to shareholders for the year ended January 31, 2018 were as follows:

	Net investment income
Class A		$3,150,526
Class B		4¹
Class C		3,401

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

TO THE SHAREHOLDERS OF THE FUND AND BOARD OF TRUSTEES OF WELLS FARGO FUNDS TRUST:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Wells Fargo Money Market Fund (the Fund), one of the funds constituting Wells Fargo Funds Trust, including the portfolio of investments, as of January 31, 2019, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years or periods in the two-year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years or periods in the five-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of January 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the years or periods in the two-year period then ended, and the financial highlights for each of the years or periods in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of January 31, 2019, by correspondence with the custodian and brokers, or by other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have not been able to determine the specific year that we began serving as the auditor of one or more Wells Fargo Funds investment companies, however we are aware that we have served as the auditor of one or more Wells Fargo Funds investment companies since at least 1955.

2 Wells Fargo National Tax-Free Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo NationalTax-Free Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo National Tax-Free Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s7-day current yield would have been 0.76%, 1.03%, 1.15%, and 0.86% for Class A, Administrator Class, Premier Class, and Service Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁴  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁵  Weighted average life (WAL): An average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. The calculation of WAL allows for the maturities of certain securities with demand features to be shortened but, unlike the calculation of WAM, does not allow shortening of the maturities of certain securities with periodic interest-rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGER’S DISCUSSION

During the period, the municipal money markets continued to strengthen as rising interest rates and increasing asset levels gave both investors and market participants something to cheer about. With regulatory reform a distant memory, market participants refocused on traditional macroeconomic factors, market technicals, and the Federal Open Market Committee (FOMC). The Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Index (SIFMA Index)⁶, which measuresseven-day variable-rate demand note (VRDN) yields, experienced several bouts of volatility throughout the period as seasonal technicals exacerbated supply and demand dynamics.Fixed-rate paper, on the other hand, experienced less dramatic swings and generally tracked taxable rates as the FOMC progressed with four rate hikes throughout the year.

The SIFMA Index began the period at 1.08% (73% of theone-week London Interbank Offered Rate [LIBOR]) as the advent of seasonal reinvestment cash in early January forced municipal money market yields to quickly normalize following a spike intax-exempt rates in December. The SIFMA Index had closed out 2017 at a multiyear high of 1.71% (115% of theone-week LIBOR). Yields on high-gradeone-year notes began the period at 1.40%, down from 1.46% at the prioryear-end.

The next big move in the municipal money market space occurred during the March through Apriltax-payment period. Yields rose across the curve as seasonal fund outflows exerted downward pressure on demand. With municipal money market funds losing roughly $4 billion in assets, the SIFMA Index spiked to 1.81% on April 18, 2018, up from 1.58% at the end of March, pushing the SIFMAIndex/one-week LIBOR ratio down to 104%.

Municipal money market assets usually languish until June and July, when coupons and maturities generate a new wave of reinvestment cash. However, fund assets staged an unexpected turnaround during the month of May as investors sought to take advantage of the sudden cheapness of the SIFMA Index, with municipal money market funds attracting almost $7 billion in assets during the month. This unexpected surge in demand forced the SIFMA Index lower for six straight weeks before closing out the month at 1.06%, or 61% of theone-week LIBOR.

June saw equally abnormal asset flows; this time, municipal money market funds experienced redemptions in the neighborhood of $2.8 billion. This surprising reversal in trend caused demand for overnight and weekly VRDNs and tender option bonds (TOBs) to evaporate, forcing dealers to rapidly ratchet rates higher in order to entice nontraditional buyers. The FOMC rate hike on June 13, 2018, provided additional impetus for thetax-exempt market to playcatch-up with taxable equivalents. The SIFMA Index rose from 1.05% (59% of theone-week LIBOR) on June 6 to 1.51% (76% of theone-week LIBOR) on June 27.

The dog days of summer brought some semblance of normalcy to the municipal money market space as the SIFMA Index settled into a narrower range while tracking taxable rates higher leading up to the next anticipated FOMC tightening in September 2018. The SIFMA Index rose slightly to 1.61% by the end of October, up from 1.56% at the end of September. Further out on the curve, yields on high-grade commercial paper and notes continued to rise as the market continued to cope with large secondary market balances.One-year high-grade notes finished out the month at approximately 2.07%, up from 1.94% the previous month.

Heading into the final two months of 2018, the municipal money markets continued to benefit as heightened equity and bond market volatility forced many investors to seek out safe havens in the short end. The municipal yield curve began to flatten as the SIFMA Index eventually drifted higher before closing out the year at 1.71%. Meanwhile, yields ontop-ratedone-year paper fell to roughly 1.90% as expectations for FOMC rate hikes were discounted. Ultimately, municipal money market funds would bring in roughly $6.5 billion in assets during the month of December, capping off a strong year in which assets increased by approximately $14 billion, or 10% for the year, according to Crane Data LLC.

In January 2019, seasonal technicals in the form of heavy maturities and coupons would drive demand fortax-exempt paper along the curve. The SIFMA Index fell sharply to a multi-month low of 1.43% (59% of theone-week LIBOR) by the end of the period as demand for VRDNs and TOBs outpaced supply. Holiday-shortened weeks also contributed to a lackluster primary market calendar, further suppressing rates. Further out on the curve, yields on high-gradeone-year paper fell to 1.74%, down from 1.90% the previous month.

Strategic outlook

Throughout the period, we continued to emphasize portfolio liquidity by targeting our purchases primarily in daily and weekly VRDNs and TOBs. This strategy allowed us to achieve our objectives for 100% weekly liquidity and principal preservation. Additionally, our strategy allowed us to quickly capture the benefits of rising interest rate levels due to FOMC rate hikes and periods of elevated SIFMA Index rates. Given the relative flatness of the municipal yield curve and uncertainty surrounding FOMC interest rate policy, we continue to feel that a conservative posture with respect to liquidity and duration targets is warranted in the near future.

Fund expenses (unaudited) Wells Fargo National Tax-Free Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

Notes to financial statements Wells Fargo National Tax-Free Money Market Fund 27

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo NationalTax-Free Money Market Fund (the “Fund”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

As permitted under Rule2a-7 of the 1940 Act, portfolio securities are valued at amortized cost, which approximates fair value. The amortized cost method involves valuing a security at its cost, plus accretion of discount or minus amortization of premium over the period until maturity.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Funds. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that aremarked-to-market daily. The collateral may be held by an agent bank under atri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

28 Wells Fargo National Tax-Free Money Market Fund Notes to financial statements

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable andtax-exempt income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the cost of investments for federal income tax purposes is substantially the same as for financial reporting purposes.

Class allocations

The separate classes of shares offered by the Fund differ principally in shareholder servicing and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities as of January 31, 2019:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
Assets
Investments in:
Municipal obligations	$	0	$	881,490,500	$	0	$	881,490,500
Other		0		10,000,000		0		10,000,000
Repurchase agreements		0		10,000,000		0		10,000,000
Total assets	$	0	$	901,490,500	$	0	$	901,490,500

Additional sector, industry or geographic detail is included in the Portfolio of Investments.

At January 31, 2019, the Fund did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement.

Notes to financial statements Wells Fargo National Tax-Free Money Market Fund 29

Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As compensation for its services under the investment management agreement, Funds Management is entitled to receive an annual management fee starting at 0.15% and declining to 0.13% as the average daily net assets of the Fund increase. For the year ended January 31, 2019, the management fee was equivalent to an annual rate of 0.15% of the Fund’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers.

As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A		0.22	%
Administrator Class		0.10
Premier Class		0.08
Service Class		0.12

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.60% for Class A shares, 0.30% for Administrator Class shares, 0.20% for Premier Class shares, and 0.45% for Service Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Prior to June 1, 2018, the Fund’s expenses were capped at 0.64% for Class A shares.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A and Service Class of the Fund is charged a fee at an annual rate of 0.25% of the respective average daily net assets of each class. Administrator Class is charged a fee at an annual rate of 0.10% of its average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices. Pursuant to these procedures, the Fund had $691,025,000 and $498,260,000 in interfund purchases and sales, respectively, during the year ended January 31, 2019.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid during the years ended January 31, 2019 and January 31, 2018 were as follows:

	Year ended January 31
	2019		2018
Ordinary income	$	722,557	$	284,906
Tax-exempt income		9,342,088		2,909,850
Long-term capital gain		242		166,556

30 Wells Fargo National Tax-Free Money Market Fund Notes to financial statements

As of January 31, 2019, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	Undistributed tax-exempt income	Undistributed long-term gain
$18,353	$159,558	$14,513

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders under U.S. generally accepted accounting principles. The amounts of distributions to shareholders for the year ended January 31, 2018 were as follows:

	Net investment income		Net realized gains
Class A		$382,804		$54,456
Administrator Class		905,450		62,316
Premier Class		1,498,368		95,599
Service Class		332,806		29,513

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

7. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Cash Investment Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo Cash Investment Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Ratesfor 10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo Cash Investment Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

4 Wells Fargo Cash Investment Money Market Fund Letter to shareholders (unaudited)

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

Don’t let short-term uncertainty derail long-term investment goals.

To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles.

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at the amounts shown. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s7-day current yield would have been 2.31%, 2.43%, 2.47%, and 2.14% for Administrator Class, Institutional Class, Select Class, and Service Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁴  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁵  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGERS’ DISCUSSION

For most of the reporting period, continued economic improvement allowed the Federal Open Market Committee (FOMC) to remove policy accommodation on a fairly predictable quarterly basis. The U.S. economy achieved above-trend growth, low unemployment, and moderating inflation at the same time as fiscal policy was proving to be an economic tailwind. The FOMC’s Summary of Economic Projections (SEP) through September reflected this scenario and provided the market with some clarity as to the path of future interest rate policy. However, the economic landscape changed in the fourth quarter as the U.S. engaged in various trade wars, the midterm elections disrupted the legislative composition, and financial conditions tightened. These factors began softening economic data and confidence, leading to increased volatility in risk assets. At the conclusion of the FOMC policy meeting on December 19, 2018, the federal funds target rate was raised to a target range of between 2.25% to 2.50% while the rate of interest on excess reserves (IOER) was increased by only 20 basis points (bps; 100 bps equal 1.00%) to 2.40%. That was the second time the IOER rate was increased 5 bps less than the increase in the target rate in an effort to keep the effective federal funds rate from drifting to the upper level of the target range.

In the accompanying SEP, the FOMC provided insight on its view of the economy, inflation, and the corresponding monetary policy expected over the next few years. And the December projections did not disappoint market observers, with the FOMC marginally decreasing its outlook on growth and inflation and correspondingly lowering the glide path for its target rate, decreasing its median outlook for interest rate hikes in 2019 from three to two (2.875%). Comparing the September and December target rate projections, the longer-term section points to an expectation of the eventual neutral rate being marginally lower at 2.75% and lowered 2020 and 2021 median interest rate expectations at 3.125%. On the growth front, the 2019 median gross domestic product projection edged down 0.2% to 2.3% while 2020 and 2021 growth projections remained unchanged at 2.0% and 1.8%, respectively. Core inflation in the 2019 to 2021 projections all declined 0.1% to 2.0%. The lower expectations for interest rates in the next three years show the FOMC members are less concerned regarding the potential for inflationary pressures and more focused on balancing a somewhat softer economy. In fact, the statement released at the conclusion of the January 2019 FOMC meeting removed the wording of “some further gradual increases,” citing increasing downside risk from abroad, weaker domestic data, and tighter financial conditions.

As the FOMC’s expectations for rate increases moved lower, the market expectations for federal funds rate increases, as measured by federal funds futures, moved even lower still. Market participants are barely pricing in any rate hike in 2019 and may even be starting to prepare for a possible rate cut toward the end of 2019 and into 2020. The U.S. Federal Reserve will have plenty of opportunities to adjust expectations starting in 2019 as Chair Jerome Powell will conduct a press conference after each FOMC meeting instead of only quarterly. On the heels of the FOMC lowering its economic and inflation projections, risk assets underperformed and U.S. equities are teetering near bear-market territory.

The rise in short rates has brought not only attention but perhaps also nontraditional money market investors (those who typically invest in longer-term debt or equities) into the short end of the market. The Crane Prime Institutional Money Market Index, maintained by Crane Data LLC⁶, was up over $61 billion during the period, with all prime assets up over $152 billion. Investors reexamining this product are realizing that the changes implemented from the 2010 money market reform have made a material difference in the construction of prime money market fund portfolios. The added liquidity requirements and maturity restrictions have had a beneficial impact on dampening net asset value (NAV) volatility even as the FOMC continued to raise rates and credit spreads widened. In addition, added transparency of holdings can provide a daily view of the portfolio construction process and allow shareholders to assess portfolio risks.

Strategic outlook

The FOMC has pivoted from a gradually removing accommodation outlook to a data-dependent stance requiring what it terms as “patience.” Going forward, money market investors should continue to look toward the FOMC and other market indicators for future rate guidance. As we get more clarity as to the end of the tightening cycle, money market participants may look to extend weighted average maturities (WAMs) to capture higher yields. Our strategy of emphasizing highly liquid portfolios, relatively short WAMs, and a position in securities that reset frequently allows us to capture elevated London Interbank Offered Rate levels with minimal NAV pricing pressures and afford the flexibility to add longer-dated securities as opportunities arise.

Fund expenses (unaudited) Wells Fargo Cash Investment Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

¹  Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect theone-half-year period).

Notes to financial statements Wells Fargo Cash Investment Money Market Fund 23

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Cash Investment Money Market Fund (the “Fund”) which is a diversified series of the Trust.

The Fund operates as an institutional non-government money market fund. As an institutional non-government money market fund, shareholders will transact at a floating net asset value (NAV) rounded to four decimal-places in accordance with the valuation policies below.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

Debt securities are valued at the evaluated bid price provided by an independent pricing service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that aremarked-to-market daily. The collateral may be held by an agent bank under atri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis aremarked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest

receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the aggregate cost of all investments for federal income tax purposes was $1,546,195,819 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	171,796
Gross unrealized losses		(22,371	)
Net unrealized gains	$	149,425

Class allocations

The separate classes of shares offered by the Fund differ principally in shareholder servicing and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities as of January 31, 2019:

Funds Management has retained the services of certain subadvisers to provide daily portfolio management to the Fund. Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is a subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Institutional Class		0.08
Select Class		0.04
Service Class		0.12

26 Wells Fargo Cash Investment Money Market Fund Notes to financial statements

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.35% for Administrator Class shares, 0.20% for Institutional Class shares, 0.13% for Select Class shares and 0.50% for Service Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Administrator Class and Service Class of the Fund are charged a fee at an annual rate of 0.10% and 0.25%, respectively, of their average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid was $28,696,486 and $19,365,262 of ordinary income for the years ended January 31, 2019 and January 31, 2018, respectively.

	Net investment income
Administrator Class		$1,125,792

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

7. NEW ACCOUNTING PRONOUNCEMENT

Report of independent registered public accounting firm Wells Fargo Cash Investment Money Market Fund 27

TO THE SHAREHOLDERS OF THE FUND AND BOARD OF TRUSTEES OF WELLS FARGO FUNDS TRUST:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Wells Fargo Cash Investment Money Market Fund (the Fund), one of the funds constituting Wells Fargo Funds Trust, including the portfolio of investments, as of January 31, 2019, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years in the five-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of January 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of January 31, 2019, by correspondence with the custodian and brokers, or by other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have not been able to determine the specific year that we began serving as the auditor of one or more Wells Fargo Funds investment companies, however we are aware that we have served as the auditor of one or more Wells Fargo Funds investment companies since at least 1955.

2 Wells Fargo Heritage Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo Heritage Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo Heritage Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at the amounts shown. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s7-day current yield would have been 2.34%, 2.46%, 2.50%, and 2.17% for Administrator Class, Institutional Class, Select Class, and Service Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Historical performance shown for Service Class shares prior to their inception reflects the performance of Administrator Class shares and has not been adjusted to reflect the higher expenses applicable to Service Class shares. If these expenses had been adjusted, returns for Service Class shares would be lower.

⁴  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁵  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁶  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGERS’ DISCUSSION

For most of the reporting period, continued economic improvement allowed the Federal Open Market Committee (FOMC) to remove policy accommodation on a fairly predictable quarterly basis. The U.S. economy achieved above-trend growth, low unemployment, and moderating inflation at the same time as fiscal policy was proving to be an economic tailwind. The FOMC’s Summary of Economic Projections (SEP) through September reflected this scenario and provided the market with some clarity as to the path of future interest rate policy. However, the economic landscape changed in the fourth quarter as the U.S. engaged in various trade wars, the midterm elections disrupted the legislative composition, and financial conditions tightened. These factors began softening economic data and confidence, leading to increased volatility in risk assets. At the conclusion of the FOMC policy meeting on December 19, 2018, the federal funds target rate was raised to a target range of between 2.25% to 2.50% while the rate of interest on excess reserves (IOER) was increased by only 20 basis points (bps; 100 bps equal 1.00%) to 2.40%. That was the second time the IOER rate was increased 5 bps less than the increase in the target rate in an effort to keep the effective federal funds rate from drifting to the upper level of the target range.

In the accompanying SEP, the FOMC provided insight on its view of the economy, inflation, and the corresponding monetary policy expected over the next few years. And the December projections did not disappoint market observers, with the FOMC marginally decreasing its outlook on growth and inflation and correspondingly lowering the glide path for its target rate, decreasing its median outlook for interest rate hikes in 2019 from three to two (2.875%). Comparing the September and December target rate projections, the longer-term section points to an expectation of the eventual neutral rate being marginally lower at 2.75% and lowered 2020 and 2021 median interest rate expectations at 3.125%. On the growth front, the 2019 median gross domestic product projection edged down 0.2% to 2.3% while 2020 and 2021 growth projections remained unchanged at 2.0% and 1.8%, respectively. Core inflation in the 2019 to 2021 projections all declined 0.1% to 2.0%. The lower expectations for interest rates in the next three years show the FOMC members are less concerned regarding the potential for inflationary pressures and more focused on balancing a somewhat softer economy. In fact, the statement released at the conclusion of the January 2019 FOMC meeting removed the wording of “some further gradual increases,” citing increasing downside risk from abroad, weaker domestic data, and tighter financial conditions.

As the FOMC’s expectations for rate increases moved lower, the market expectations for federal funds rate increases, as measured by federal funds futures, moved even lower still. Market participants are barely pricing in any rate hike in 2019 and may even be starting to prepare for a possible rate cut toward the end of 2019 and into 2020. The U.S. Federal Reserve will have plenty of opportunities to adjust expectations starting in 2019 as Chair Jerome Powell will conduct a press conference after each FOMC meeting instead of only quarterly. On the heels of the FOMC lowering its economic and inflation projections, risk assets underperformed and U.S. equities are teetering near bear-market territory.

The rise in short rates has brought not only attention but perhaps also nontraditional money market investors (those who typically invest in longer-term debt or equities) into the short end of the market. The Crane Prime Institutional Money Market Index, maintained by Crane Data LLC⁷, was up over $61 billion period over period, with all prime assets up over $152 billion. Investors reexamining this product are realizing that the changes implemented from the 2010 money market reform have made a material difference in the construction of prime money market fund portfolios. The added liquidity requirements and maturity restrictions have had a beneficial impact on dampening net asset value (NAV) volatility even as the FOMC continued to raise rates and credit spreads widened. In addition, added transparency of holdings can provide a daily view of the portfolio construction process and allow shareholders to assess portfolio risks.

Strategic outlook

The FOMC has pivoted from a gradually removing accommodation outlook to a data-dependent stance requiring what it terms as “patience.” Going forward, money market investors should continue to look toward the FOMC and other market indicators for future rate guidance. As we get more clarity as to the end of the tightening cycle, money market participants may look to extend weighted average maturities (WAMs) to capture higher yields. Our strategy of emphasizing highly liquid portfolios, relatively short WAMs, and a position in securities that resets frequently allows us to capture elevated London Interbank Offered Rate levels with minimal NAV pricing pressures and afford the flexibility to add longer-dated securities as opportunities arise.

Fund expenses (unaudited) Wells Fargo Heritage Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

	Beginning account value 8-1-2018		Ending account value 1-31-2019		Expenses paid during the period¹		Annualized net expense ratio

Hypothetical (5% return before expenses)	$	1,000.00	$	1,023.04	$	2.19		0.43	%

¹ Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect theone-half-year period).

24 Wells Fargo Heritage Money Market Fund Notes to financial statements

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Heritage Money Market Fund (the “Fund”) which is a diversified series of the Trust.

The Fund operates as an institutional non-government money market fund. As an institutional non-government money market fund, shareholders will transact at a floating net asset value (NAV) rounded to four decimal-places in accordance with the valuation policies below.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

Debt securities are valued at the evaluated bid price provided by an independent pricing service service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that aremarked-to-market daily. The collateral may be held by an agent bank under atri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis aremarked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest

Notes to financial statements Wells Fargo Heritage Money Market Fund 25

receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the aggregate cost of all investments for federal income tax purposes was $8,258,663,512 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	1,056,778
Gross unrealized losses		(119,275	)
Net unrealized gains	$	937,503

Class allocations

The separate classes of shares offered by the Fund differ principally in shareholder servicing and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

Funds Management has retained the services of certain subadvisers to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is a subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Administrator Class		0.10	%
Institutional Class		0.08
Select Class		0.04
Service Class		0.12

Notes to financial statements Wells Fargo Heritage Money Market Fund 27

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.35% for Administrator Class shares, 0.20% for Institutional Class shares, 0.13% for Select Class shares, and 0.43% for Service Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Administrator Class and Service Class of the Fund are charged a fee at an annual rate of 0.10% and 0.25%, respectively, of their average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid was $159,851,992 and $64,074,227 of ordinary income for the years ended January 31, 2019 and January 31, 2018, respectively.

As of January 31, 2019, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	Unrealized gains

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

7. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.

In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of January 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud.

2 Wells Fargo Municipal Cash Management Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo Municipal Cash Management Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo Municipal Cash Management Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at the amounts shown. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s 7-day current yield would have been 1.04%, 1.15%, and 0.86% for Administrator Class, Institutional Class, and Service Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Historical performance shown for Administrator Class shares prior to their inception reflects the performance of Institutional Class shares, and has not been adjusted to include the higher expenses applicable to Administrator Class shares. If these expenses had been included, returns for Administrator Class shares would be lower.

⁴  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁵  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁶  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

⁷  The Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Index (SIFMA Index) is a seven-day high-grade market index composed of tax-exempt variable-rate demand obligations with certain characteristics. The index is calculated and published by Bloomberg. The index is overseen by SIFMA’s Municipal Swap Index Committee. You cannot invest directly in an index.

MANAGER’S DISCUSSION

During the period, the municipal money markets continued to strengthen as rising interest rates and increasing asset levels gave both investors and market participants something to cheer about. With regulatory reform a distant memory, market participants refocused on traditional macroeconomic factors, market technicals, and the Federal Open Market Committee (FOMC). The Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Index (SIFMA Index)⁷, which measures seven-day variable-rate demand note (VRDN) yields, experienced several bouts of volatility throughout the period as seasonal technicals exacerbated supply and demand dynamics. Fixed-rate paper, on the other hand, experienced less dramatic swings and generally tracked taxable rates as the FOMC progressed with four rate hikes throughout the year.

The SIFMA Index began the period at 1.08% (73% of the one-week London Interbank Offered Rate [LIBOR]) as the advent of seasonal reinvestment cash in early January forced municipal money market yields to quickly normalize following a spike in tax-exempt rates in December. The SIFMA Index had closed out 2017 at a multiyear high of 1.71% (115% of the one-week LIBOR). Yields on high-grade one-year notes began the period at 1.40%, down from 1.46% at the prior year-end.

The next big move in the municipal money market space occurred during the March through April tax-payment period. Yields rose across the curve as seasonal fund outflows exerted downward pressure on demand. With municipal money market funds losing roughly $4 billion in assets, the SIFMA Index spiked to 1.81% on April 18, 2018, up from 1.58% at the end of March, pushing the SIFMA Index/one-week LIBOR ratio down to 104%.

Municipal money market assets usually languish until June and July, when coupons and maturities generate a new wave of reinvestment cash. However, fund assets staged an unexpected turnaround during the month of May as investors sought to take advantage of the sudden cheapness of the SIFMA Index, with municipal money market funds attracting almost $7 billion in assets during the month. This unexpected surge in demand forced the SIFMA Index lower for six straight weeks before closing out the month at 1.06%, or 61% of one-week LIBOR.

June saw equally abnormal asset flows; this time, municipal money market funds experienced redemptions in the neighborhood of $2.8 billion. This surprising reversal in trend caused demand for overnight and weekly VRDNs and tender option bonds (TOBs) to evaporate, forcing dealers to rapidly ratchet rates higher in order to entice nontraditional buyers. The FOMC rate hike on June 13, 2018, provided additional impetus for the tax-exempt market to play catch-up with taxable equivalents. The SIFMA Index rose from 1.05% (59% of the one-week LIBOR) on June 6 to 1.51% (76% of the one-week LIBOR) on June 27.

The dog days of summer brought some semblance of normalcy to the municipal money market space as the SIFMA Index settled into a narrower range while tracking taxable rates higher leading up to the next anticipated FOMC tightening in September 2018. The SIFMA Index rose slightly to 1.61% by the end of October, up from 1.56% at the end of September. Further out on the curve, yields on high-grade commercial paper and notes continued to rise as the market continued to cope with large secondary market balances. One-year high-grade notes finished out the month at approximately 2.07%, up from 1.94% the previous month.

Heading into the final two months of 2018, the municipal money markets continued to benefit as heightened equity and bond market volatility forced many investors to seek out safe havens in the short end. The municipal yield curve began to flatten as the SIFMA Index eventually drifted higher before closing out the year at 1.71%. Meanwhile, yields on top-rated one-year paper fell to roughly 1.90% as expectations for FOMC rate hikes were discounted. Ultimately, municipal money market funds would bring in roughly $6.5 billion in assets during the month of December, capping off a strong year in which assets increased by approximately $14 billion, or 10% for the year, according to Crane Data LLC.

In January 2019, seasonal technicals in the form of heavy maturities and coupons would drive demand for tax-exempt paper along the curve. The SIFMA Index fell sharply to a multi-month low of 1.43% (59% of the one-week LIBOR) by the end of the period as demand for VRDNs and TOBs outpaced supply. Holiday-shortened weeks also contributed to a lackluster primary market calendar, further suppressing rates. Further out on the curve, yields on high-grade one-year paper fell to 1.74%, down from 1.90% the previous month.

Strategic outlook

Throughout the period, we continued to emphasize portfolio liquidity by targeting our purchases primarily in daily and weekly VRDNs and TOBs. This strategy allowed us to achieve our objectives for 100% weekly liquidity and principal preservation. Additionally, our strategy allowed us to quickly capture the benefits of rising interest rate levels due to FOMC rate hikes and periods of elevated SIFMA Index rates. Given the relative flatness of the municipal yield curve and uncertainty surrounding FOMC interest rate policy, we continue to feel that a conservative posture with respect to liquidity and duration targets is warranted in the near future.

Fund expenses (unaudited) Wells Fargo Municipal Cash Management Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

	Beginning account value 8-1-2018		Ending account value 1-31-2019		Expenses paid during the period¹		Annualized net expense ratio

¹ Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect the one-half-year period).

22 Wells Fargo Municipal Cash Management Money Market Fund Notes to financial statements

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946,Financial Services – Investment Companies. These financial statements report on the Wells Fargo Municipal Cash Management Money Market Fund (the “Fund”) which is a diversified series of the Trust.

The Fund operates as an institutional non-government money market fund. As an institutional non-government money market fund, shareholders will transact at a floating net asset value (NAV) rounded to four decimal places in accordance with the valuation policies below.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

Debt securities are valued at the evaluated bid price provided by an independent pricing service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that are marked-to-market daily. The collateral may be held by an agent bank under a tri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed on non-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed from non-accrual status.

Distributions to shareholders

Distributions to shareholders from net investment income are accrued daily and paid monthly. Distributions from net realized gains, if any, are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital.

Notes to financial statements Wells Fargo Municipal Cash Management Money Market Fund 23

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable and tax-exempt income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the aggregate cost of all investments for federal income tax purposes was $185,150,000 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	0
Gross unrealized losses		0
Net unrealized gains	$	0

Class allocations

The separate classes of shares offered by the Fund differ principally in shareholder servicing and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities as of January 31, 2019:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
Assets
Municipal obligations	$	0	$	157,550,000	$	0	$	157,550,000
Other		0		22,700,000		0		22,700,000
Repurchase agreements		0		4,900,000		0		4,900,000
Total assets	$	0	$	185,150,000	$	0	$	185,150,000

Additional sector, industry or geographic detail is included in the Portfolio of Investments.

At January 31, 2019, the Fund did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement.

24 Wells Fargo Municipal Cash Management Money Market Fund Notes to financial statements

Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As compensation for its services under the investment management agreement, Funds Management is entitled to receive an annual management fee starting at 0.15% and declining to 0.13% as the average daily net assets of the Fund increase. For the year ended January 31, 2019, the management fee was equivalent to an annual rate of 0.15% of the Fund’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent, sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Administrator Class		0.10	%
Institutional Class		0.08
Service Class		0.12

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.30% for Administrator Class shares, 0.20% for Institutional Class shares, and 0.45% for Service Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents. Administrator Class and Service Class of the Fund are charged a fee at an annual rate of 0.10% and 0.25%, respectively, of their average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices. Pursuant to these procedures, the Fund had $493,940,000 and $519,565,000 in interfund purchases and sales, respectively, during the year ended January 31, 2019.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid during the years ended January 31, 2019 and January 31, 2018 were as follows:

	Year ended January 31
	2019		2018
Ordinary income	$	473,017	$	261,220
Tax-exempt income		2,857,604		2,409,487
Long-term capital gain		143,132		0

Notes to financial statements Wells Fargo Municipal Cash Management Money Market Fund 25

As of January 31, 2019, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	Undistributed tax-exempt income
$1,837	$62,757

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders under U.S. generally accepted accounting principles. The amounts of distributions to shareholders for the year ended January 31, 2018 were as follows:

	Net investment income		Net realized gains
Administrator Class	$	22,145	$	9
Institutional Class		2,533,504		1,014
Service Class		113,982		53

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

7. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Government Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo Government Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo Government Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

4 Wells Fargo Government Money Market Fund Letter to shareholders (unaudited)

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

Don’t let short-term uncertainty derail long-term investment goals.

To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles.

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at 0.60% for Class A, 0.35% for Administrator Class, 0.20% for Institutional Class, 0.14% for Select Class, 0.50% for Service Class, and 0.77% for the Sweep Class. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s7-day current yield would have been 1.86%, 2.13%, 2.25%, 2.29%, 1.96%, and 1.70% for Class A, Administrator Class, Institutional Class, Select Class, Service Class, and Sweep Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Historical performance shown for the Select Class shares prior to their inception reflects the performance of the Institutional Class shares, and includes the higher expenses applicable to Institutional Class shares. If these expenses had not been included, returns for Select Class shares would be higher.

⁴  Historical performance shown for Sweep Class shares prior to their inception reflects the performance of Service Class shares, and has not been adjusted to include the higher expenses applicable to Sweep Class shares. If these expenses had been included, returns for Sweep Class shares would be lower.

⁵  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁶  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁷  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGER’S DISCUSSION

The Fund’s fiscal year that ended January 31, 2019, was characterized by steadily rising interest rates. The fiscal year began with the target range on the federal funds rate set by the U.S. Federal Reserve (Fed) at 1.25% to 1.50%. The Fed raised the target range by 0.25% four times during the year—in March, June, September, and December—with the resulting federal funds target rate set at 2.25% to 2.50% at the end of the period. In addition to raising interest rates, the Fed also continued to shrink its balance sheet by systematically allowing a portion of the U.S. Treasury and mortgage-backed securities it acquired during its quantitative easing programs to mature without being reinvested. Both the interest rate and balance sheet actions represent steps by the Fed to normalize monetary policy, effectively unwinding the policies it used to assist the economy’s recovery from the financial crisis.

The U.S. economy grew strongly throughout the year. Gross domestic product grew at an average rate of approximately 3.1% on an annualized basis, compared with a solid 2.5% rate for the prior year. The unemployment rate was largely unchanged, ending the fiscal year at 4.0%, down from 4.1% a year earlier. In addition, the underemployment rate, which includes workers marginally attached to the labor force and those working part time for economic reasons, also fell slightly, from 8.2% to 8.1% over the same period. Both measures were at or below their lows in the years preceding the financial crisis. These measures, among others, likely gave the Fed the confidence it displayed in moving to normalize interest rates and its balance sheet.

Interest rates on all categories of government money market securities moved gradually higher throughout the year, consistent with the Fed’s moves. The3-month Treasury bill(T-bill) yields averaged 1.58% during February 2018, the first month of the fiscal year; 2.40% during January 2019, the last month of the fiscal year; and 2.04% on average for the entire fiscal year. This compares with an average of 1.01% for the year that ended January 31, 2018. Similarly, average6-monthT-bill yields were 1.77% in February 2018; 2.50% in January 2019; and 2.21% over the whole fiscal year, up from an average of 1.14% in the previous fiscal year. The higher yields onT-bills were due not only to the Fed’s interest rate hikes but also to an increased supply ofT-bills from the U.S. Treasury, which needed to finance the growing U.S. federal deficit. The total amount ofT-bills outstanding grew from $1.964 trillion at the beginning of the fiscal year to $2.289 trillion at the end.

The yields on repurchase agreements (repos) generally followed the same path and were also heavily influenced by the Fed’s decisions. Overnight Treasury repo rates, as measured by the Fed’sTri-Party General Collateral Rate, averaged 1.31% in February 2018, the fiscal year’s first month, and 2.44% in January 2019, the fiscal year’s last month. For the entire fiscal year that ended January 31, 2019 the average Treasury repo yield was 1.92%, up from 0.94% for the previous fiscal year.

Similarly, yields on government-sponsored enterprise (GSE) discount notes moved higher in lockstep with other government securities throughout the year. Average GSE discount note yields for3-,6-, and12-month tenors were 1.00%, 1.09%, and 1.24%, respectively, in the prior reporting period. The yields moved to averages of 2.01%, 2.13%, and 2.32%, respectively, for the fiscal year that ended January 31, 2019.

Our portfolio strategy continued to emphasize maintaining both a stable $1.00 net asset value and adequate liquidity to meet shareholder redemptions. Accordingly, we invested inT-bills; U.S. Treasury notes; GSE discount notes; and other securities, including floating-rate notes and repos collateralized by Treasury securities and GSE obligations.

Strategic outlook

The economy has continued its solid performance, with a consistently strong labor market and gradually rising—but still below target—inflation. At the end of the fiscal year, the Fed signaled that it will proceed more cautiously, weighing incoming economic data and other factors and modifying its interest rate path accordingly. As the Fed is no longer projecting further gradual increases in interest rates and is instead espousing patience, the interest rate outlook as the fiscal year begins is for steady rates, and the direction of the next move in interest rates will depend on the evolution of the economy. The fiscal impulse from the federal tax cut that helped boost the economy over the past year may fade somewhat, potentially leading to slower economic growth over the following year. These factors suggest that interest rates on U.S. government money market securities may be little changed for at least the early part of the fiscal year. The risks to this outlook appear to be roughly balanced, as a still-strong economy could eventually call for higher rates, while rates could fall if the economy weakens due to a variety of factors, such as political developments in both the U.S. and abroad; a pullback in risk asset valuations; and a turn in the economic cycle, as the current expansion is well aged by historical standards. In the face of this uncertainty, we believe that our investment strategy, with its focus on capital preservation and liquidity, should enable the Fund to continue to meet its objectives.

Fund expenses (unaudited) Wells Fargo Government Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, distribution(12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

30 Wells Fargo Government Money Market Fund Notes to financial statements

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Government Money Market Fund (the “Fund”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

As permitted under Rule2a-7 of the 1940 Act, portfolio securities are valued at amortized cost, which approximates fair value. The amortized cost method involves valuing a security at its cost, plus accretion of discount or minus amortization of premium over the period until maturity.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that aremarked-to-market daily. The collateral may be held by an agent bank under atri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis aremarked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Notes to financial statements Wells Fargo Government Money Market Fund 31

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the cost of investments for federal income tax purposes is substantially the same as for financial reporting purposes.

Class allocations

The separate classes of shares offered by the Fund differ principally in distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities as of January 31, 2019:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
Assets
Investments in:
Government agency debt	$	0	$	25,454,541,261	$	0	$	25,454,541,261

At January 31, 2019, the Fund did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As compensation for its services under the investment management agreement, Funds Management is entitled to receive an annual management fee starting at 0.15% and declining to 0.13% as the average daily net assets of the Fund increase. For the year ended January 31, 2019, the management fee was equivalent to an annual rate of 0.13% of the Fund’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A		0.22	%
Administrator Class		0.10
Institutional Class		0.08
Select Class		0.04
Service Class		0.12
Sweep Class		0.03

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.60% for Class A shares, 0.35% for Administrator Class shares, 0.20% for Institutional Class shares, 0.14% for Select Class shares, 0.50% for Service Class shares, and 0.77% for Sweep Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.Prior to June 1, 2018, the Fund’s expenses were capped at 0.65% for Class A shares, 0.16% for Select Class shares, and 0.79% for Sweep Class shares.

Distribution fee

The Trust has adopted a distribution plan for Sweep Class shares of the Fund pursuant to Rule12b-1 under the 1940 Act. A distribution fee is charged to Sweep Class shares and paid to Wells Fargo Funds Distributor, LLC, the principal underwriter, at an annual rate of 0.35% of the average daily net assets of Sweep Class shares.

Notes to financial statements Wells Fargo Government Money Market Fund 33

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Service Class, and Sweep Class of the Fund are charged a fee at an annual rate of 0.25% of the respective average daily net assets of each class. Administrator Class is charged a fee at an annual rate of 0.10% of its average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid was $1,305,825,736 and $541,723,392 of ordinary income for the years ended January 31, 2019 and January 31, 2018, respectively.

As of January 31, 2019, distributable earnings on a tax basis consisted of $62,281,704 in undistributed ordinary income.

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders under U.S. generally accepted accounting principles. The amounts of distributions to shareholders for the year ended January 31, 2018 were as follows:

	Net investment income		Net realized gains
Class A	$	1,001,046	$	808
Administrator Class		5,781,998		3,433
Institutional Class		176,872,690		73,726
Select Class		343,698,404		150,798
Service Class		14,132,467		7,779
Sweep Class		242		1

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

7. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

34 Wells Fargo Government Money Market Fund Report of independent registered public accounting firm

TO THE SHAREHOLDERS OF THE FUND AND BOARD OF TRUSTEES OF WELLS FARGO FUNDS TRUST:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Wells Fargo Government Money Market Fund (the Fund), one of the funds constituting Wells Fargo Funds Trust, including the portfolio of investments, as of January 31, 2019, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years or periods in the five-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of January 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years or periods in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of January 31, 2019, by correspondence with the custodian and brokers, or by other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

2 Wells Fargo 100% Treasury Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo 100% Treasury Money Market Fund for the 12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregate ex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for 10-year and 30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. A tit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregate ex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo 100% Treasury Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregate ex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S. mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

⁸  The Russell 2000^® Index measures the performance of the 2,000 smallest companies in the Russell 3000^® Index, which represents approximately 8% of the total market capitalization of the Russell 3000^® Index. You cannot invest directly in an index.

4 Wells Fargo 100% Treasury Money Market Fund Letter to shareholders (unaudited)

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregate ex-USD Index also were positive.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Thank you for choosing to invest with Wells Fargo Funds. We appreciate your confidence in us and remain committed to helping you meet your financial needs.

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at the amounts shown. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s 7-day current yield would have been 1.76%, 2.03%, 2.15%, 1.86%, and 1.60% for Class A, Administrator Class, Institutional Class, Service Class, and Sweep Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Historical performance shown for Administrator Class shares prior to their inception reflects the performance of Service Class shares, and includes the higher expenses applicable to Service Class shares. If these expenses had not been included, returns for Administrator Class shares would be higher.

⁴  Historical performance shown for Institutional Class shares prior to their inception reflects the performance of Administrator Class shares, and includes the higher expenses applicable to Administrator Class shares. If these expenses had not been included, returns for Institutional Class shares would be higher.

⁵  Historical performance shown for Sweep Class shares prior to their inception reflects the performance of Service Class shares, and has not been adjusted to reflect the higher expenses applicable to Sweep Class shares. If these expenses had been adjusted, returns for Sweep Class shares would be lower.

⁶  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁷  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁸  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGER’S DISCUSSION

The Fund’s fiscal year that ended January 31, 2019, was characterized by steadily rising interest rates. The fiscal year began with the target range on the federal funds rate set by the U.S. Federal Reserve (the Fed) at 1.25% to 1.50%. The Fed raised the target range by 0.25% four times during the year—in March, June, September, and December—with the resulting federal funds target rate set at 2.25% to 2.50% at the end of the period. In addition to raising interest rates, the Fed also continued to shrink its balance sheet by systematically allowing a portion of the U.S. Treasury and mortgage-backed securities it acquired during its quantitative easing programs to mature without being reinvested. Both the interest rate and balance sheet actions represent steps by the Fed to normalize monetary policy, effectively unwinding the policies it used to assist the economy’s recovery from the financial crisis.

The U.S. economy grew strongly throughout the year. Gross domestic product grew at an average rate of approximately 3.1% on an annualized basis, compared with a solid 2.5% rate for the prior year. Employment data remained strong, with the unemployment rate, ending the fiscal year at 4.0%, down from 4.1% a year earlier. In addition, the underemployment rate, which includes workers marginally attached to the labor force and those working part time for economic reasons, also fell slightly, from 8.2% to 8.1% over the same period. Both measures were at or below their lows in the years preceding the financial crisis. These measures, among others, likely gave the Fed the confidence it displayed in moving to normalize interest rates and its balance sheet.

Interest rates on all categories of government money market securities moved gradually higher throughout the year, consistent with the Fed’s moves. The 3-month Treasury bill (T-bill) yields averaged 1.58% during February 2018, the first month of the fiscal year; 2.40% during January 2019, the last month of the fiscal year; and 2.04% on average for the entire fiscal year. This compares with an average of 1.01% for the year that ended January 31, 2018. Similarly, average 6-month T-bill yields were 1.77% in February 2018; 2.50% in January 2019; and averaged 2.21% over the whole fiscal year, up from an average of 1.14% in the previous fiscal year. The higher yields on T-bills were due not only to the Fed’s interest rate hikes but also to an increased supply of T-bills from the U.S. Treasury, which needed to finance the growing U.S. federal deficit. The total amount of T-bills outstanding grew from $1.964 trillion at the beginning of the fiscal year to $2.289 trillion at the end.

Our investment strategy remained consistent. We invested in T-bills and U.S. Treasury notes—including floating-rate notes—while taking into account the Fund’s overall level of liquidity and average maturity and seeking to maintain a stable $1.00 net asset value.

Strategic outlook

The economy has continued its solid performance, with a consistently strong labor market and gradually rising—but still below target—inflation. At the end of the fiscal year, the Fed signaled that it will proceed more cautiously, weighing incoming economic data and other factors and modifying its interest rate path accordingly. As the Fed is no longer projecting further gradual increases in interest rates and is instead espousing patience, the interest rate outlook as the fiscal year begins is for steady rates, and the direction of the next move in interest rates will depend on the evolution of the economy. The fiscal impulse from the federal tax cut that helped boost the economy over the past year may fade somewhat, potentially leading to slower economic growth over the following year. These factors suggest that interest rates on U.S. government money market securities may be little changed for at least the early part of the fiscal year. The risks to this outlook appear to be roughly balanced, as a still-strong economy could eventually call for higher rates, while rates could fall if the economy weakens due to a variety of factors, such as political developments in both the U.S. and abroad; a pullback in risk asset valuations; and a turn in the economic cycle, as the current expansion is well aged by historical standards. In the face of this uncertainty, we believe that our investment strategy, with its focus on capital preservation and liquidity, should enable the Fund to continue to meet its objectives.

Fund expenses (unaudited) Wells Fargo 100% Treasury Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, distribution (12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

¹ Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect the one-half-year period).

20 Wells Fargo 100% Treasury Money Market Fund Notes to financial statements

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo 100% Treasury Money Market Fund (the “Fund”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

As permitted under Rule 2a-7 of the 1940 Act, portfolio securities are valued at amortized cost, which approximates fair value. The amortized cost method involves valuing a security at its cost, plus accretion of discount or minus amortization of premium over the period until maturity.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis are marked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed on non-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed from non-accrual status.

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

Notes to financial statements Wells Fargo 100% Treasury Money Market Fund 21

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the cost of investments for federal income tax purposes is substantially the same as for financial reporting purposes.

Class allocations

The separate classes of shares offered by the Fund differ principally in distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities as of January 31, 2019:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
Assets
Investments in:
Treasury debt	$	0	$	12,625,560,424	$	0	$	12,625,560,424

Additional sector, industry or geographic detail is included in the Portfolio of Investments.

At January 31, 2019, the Fund did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As compensation for its services under the investment management agreement, Funds Management is entitled to receive an annual management fee starting at 0.20% and declining to 0.18% as the average daily net assets of the Fund increase. Prior to June 1, 2018, Funds Management received a fee at an annual rate which started at 0.35% and declined to 0.23% as the average daily net assets of the Fund increased. For the year ended January 31, 2019, the management fee was equivalent to an annual rate of 0.23% of the Fund’s average daily net assets.

22 Wells Fargo 100% Treasury Money Market Fund Notes to financial statements

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent, sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A		0.22	%
Administrator Class		0.10
Institutional Class		0.08
Service Class		0.12
Sweep Class		0.03

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.60% for Class A shares, 0.30% for Administrator Class shares, 0.20% for Institutional Class shares, 0.50% for Service Class shares, and 0.83% for Sweep Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Prior to June 1, 2018, the Fund’s expenses were capped at 0.65% for Class A shares.

Distribution fee

The Trust has adopted a distribution plan for Sweep Class shares of the Fund pursuant to Rule 12b-1 under the 1940 Act. A distribution fee is charged to Sweep Class shares and paid to Wells Fargo Funds Distributor, LLC, the principal underwriter, at an annual rate of 0.35% of the average daily net assets of Sweep Class shares.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Service Class, and Sweep Class of the Fund are charged a fee at an annual rate of 0.25% of the respective average daily net assets of each class. Administrator Class is charged a fee at an annual rate of 0.10% of its average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid during the years ended January 31, 2019 and January 31, 2018 were as follows:

	Year ended January 31
	2019		2018
Ordinary income	$	173,649,441	$	57,848,084
Long-term capital gain		0		19,586

Notes to financial statements Wells Fargo 100% Treasury Money Market Fund 23

As of January 31, 2019, distributable earnings on a tax basis consisted of $7,966,917 in undistributed ordinary income.

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders under U.S. generally accepted accounting principles. The amounts of distributions to shareholders for the year ended January 31, 2018 were as follows:

	Net investment income		Net realized gains
Class A	$	965,544	$	17,037
Administrator Class		6,627,174		59,926
Institutional Class		34,332,395		263,674
Service Class		14,586,653		158,024
Sweep Class		831,054		26,189

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses.

TO THE SHAREHOLDERS OF THE FUND AND BOARD OF TRUSTEES OF WELLS FARGO FUNDS TRUST:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Wells Fargo 100% Treasury Money Market Fund (the Fund), one of the funds constituting Wells Fargo Funds Trust, including the portfolio of investments, as of January 31, 2019, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years or periods in the five-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of January 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years or periods in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of January 31, 2019, by correspondence with the custodian and brokers, or by other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have not been able to determine the specific year that we began serving as the auditor of one or more Wells Fargo Funds investment companies, however we are aware that we have served as the auditor of one or more Wells Fargo Funds investment companies since at least 1955.

2 Wells Fargo Treasury Plus Money Market Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the second quarter of 2018.

Dear Shareholder:

We are pleased to offer you this annual report for the Wells Fargo Treasury Plus Money Market Fund for the12-month period that ended January 31, 2019. An upward trend for short-term interest rates, inflation concerns, trade tensions, and geopolitical events contributed to investment market volatility throughout the year.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ fell 2.31% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 12.58%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 14.24%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ added 2.25% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.26%. The Bloomberg Barclays Municipal Bond Index⁶ added 3.26%, and the ICE BofAML U.S. High Yield Index⁷ gained 1.57%.

A move to normalize U.S. monetary policy influenced markets.

Through January 2018, the S&P 500 Index and MSCI ACWI ex USA Index (Net) delivered positive returns every month for more than a year. In February 2018, that streak ended. The S&P 500 Index fell 3.69% during February and the MSCI ACWI ex USA Index (Net) dropped 4.72%. For the quarter, the S&P 500 Index recorded its first negative quarterly return since 2014. The MSCI ACWI ex USA Index (Net) fell 1.18% for the quarter.

During the year, the U.S. Federal Reserve (Fed) sought to normalize accommodative monetary policies in place since the 2008 global financial crisis and recession. Short-term interest rates, as measured by U.S. Treasury bills—maturities ranging from 3 to 12 months—increased an average of 89 basis points (bps; 100 bps equal 1.00%). Rates for10-year and30-year Treasuries increased 17 bps and 18 bps, respectively. Slower growth of long-term rates raised concerns for a flattening yield curve, sometimes associated with recessions. The Fed raised the federal funds rate by 25 bps in March 2018 to a target range of between 1.50% and 1.75%. The Bank of England (BOE) indicated a bias to increase rates later in 2018. The European Central Bank, the Bank of Japan, and the People’s Bank of China (PBOC) maintained low interest rates.

Global trade tensions heightened investor concerns.

Global trade tensions escalated during the second quarter of 2018. Atit-for-tat tariff spat intensified between the U.S. and other governments. The Fed raised the federal funds rate by 25 bps to a target range of between 1.75% and 2.00% in June. Market index results reflected the global concerns. The MSCI ACWI ex USA Index (Net) lost 2.61% while the Bloomberg Barclays Global Aggregateex-USD Index dropped 4.76%.

Letter to shareholders (unaudited) Wells Fargo Treasury Plus Money Market Fund 3

Not all news was bad. The U.S. Bureau of Economic Analysis reported second-quarter gross domestic product (GDP) annualized growth of 4.2%. Hiring improved. Employment data remained strong. Consumer confidence and spending increased. The S&P 500 Index recorded a 3.43% second-quarter gain. Stocks of companies with smaller capitalizations were even better, as measured by the Russell 2000^® Index,⁸ adding 7.75%.

Investors appeared to shake off lingering concerns during the third quarter.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors. U.S. trade negotiations with Mexico and Canada progressed. The Conference Board Consumer Confidence Index^®9 reached its highest level in 18 years during September. The Fed raised the federal funds rate by 25 bps to a target range of between 2.00% and 2.25% in September. For the quarter that ended September 30, 2018, the S&P 500 Index added 7.71%.

Investors in international markets were not as reassured. Tensions between the U.S. and China increased. The U.S. imposed $200 billion in tariffs on Chinese goods. China reacted with $60 billion in tariffs on U.S. goods. Economic growth in China caused concern. The BOE raised its monetary policy rate to 0.75% in August. During the quarter, the MSCI ACWI ex USA Index (Net) gained 0.71%. The MSCI EM Index (Net) declined 1.09%. In fixed-income markets, U.S. bonds were flat, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index. The Bloomberg Barclays Global Aggregateex-USD Index fell 1.74%.

Conflicting data unsettled markets during the fourth quarter.

For the S&P 500 Index and the MSCI ACWI ex USA Index (Net), negative stock market performance during October and December bracketed positive November returns. December’s S&P 500 Index performance was the worst since 1931. Globally, fixed-income investments fared better than stocks during the last two months of the year.

November’s U.S.mid-term elections shifted control of the House of Representatives from Republicans to Democrats, presaging potential partisan clashes. The Bureau of Economic Analysis reported that third-quarter U.S. GDP grew at an annualized 3.4% rate, solid, but lower than the second quarter rate. Brexit efforts stalled ahead of the March 2019 deadline. The PBOC cut reserve requirement ratios, accelerated infrastructure spending, and cut taxes even as the value of the yuan declined to low levels last seen in 2008.

After the Fed increased the federal funds rate by 25 bps to a target range of between 2.25% and 2.50% in December—the ninth such increase since the Fed began three years ago to raise rates from near zero—it softened its outlook for further interest rate increases in 2019.

The market climbs a wall of worry.

Investors entered 2019 with reasons to be concerned. A partial U.S government shutdown driven by partisan spending and immigration policy disputes extended into January. Investors expected high levels of stock market volatility to continue based on the VIX¹⁰.

Favorable third-quarter economic indicators and corporate earnings reports encouraged domestic stock investors.

⁸  The Russell 2000^® Index measures the performance of the 2,000 smallest companies in the Russell 3000^® Index, which represents approximately 8% of the total market capitalization of the Russell 3000^® Index. You cannot invest directly in an index.

⁹  The Conference Board Consumer Confidence Index^® measures the degree of optimism on the state of the U.S. economy that consumers are expressing through their activities of savings and spending. You cannot invest directly in an index.

4 Wells Fargo Treasury Plus Money Market Fund Letter to shareholders (unaudited)

January’s returns tended to support the investing adage that markets climb a wall of worry. The S&P 500 Index gained 8.01% for the month that ended January 31, 2019, its best monthly performance in 30 years. Returns for the MSCI ACWI ex USA Index (Net), the Bloomberg Barclays U.S. Aggregate Bond Index, and the Bloomberg Barclays Global Aggregateex-USD Index also were positive.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Thank you for choosing to invest with Wells Fargo Funds. We appreciate your confidence in us and remain committed to helping you meet your financial needs.

Sincerely,

Andrew Owen

¹  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

²  The manager has contractually committed through May 31, 2019 (May 31, 2020 for Administrator Class and Sweep Class), to waive fees and/or reimburse expenses to the extent necessary to cap the expenses of each class after fee waivers at 0.60% for Class A, 0.34% for Administrator Class, 0.20% for Institutional Class, 0.45% for Service Class, and 0.77% for Sweep Class. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from the expense cap. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Without this cap, the Fund’s returns would have been lower. Without waived fees and/or reimbursed expenses, the Fund’s 7-day current yield would have been 1.84%, 2.11%, 2.23%, 1.94%, and 1.68% for Class A, Administrator Class, Institutional Class, Service Class, and Sweep Class, respectively. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

³  Historical performance shown for Sweep Class shares prior to their inception reflects the performance of Class A shares, and has not been adjusted to include the higher expenses applicable to Sweep Class shares. If these expenses had been adjusted, returns for Sweep Class shares would be lower.

⁴  Amounts are calculated based on the total investments of the Fund. These amounts are subject to change and may have changed since the date specified.

⁵  Weighted Average Maturity (WAM): WAM is an average of the effective maturities of all securities held in the portfolio, weighted by each security’s percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. WAM calculations allow for the maturities of certain securities with demand features or periodic interest rate resets to be shortened. WAM is a way to measure a fund’s sensitivity to potential interest rate changes. WAM is subject to change and may have changed since the date specified.

⁶  Weighted Average Life (WAL): WAL is an average of the final maturities of all securities held in the portfolio, weighted by their percentage of total investments. The maturity of a portfolio security is the period remaining until the date on which the principal amount is unconditionally required to be paid, or in the case of a security called for redemption, the date on which the redemption payment is unconditionally required to be made. In contrast to WAM, the calculation of WAL allows for the maturities of certain securities with demand features to be shortened, but not the periodic interest rate resets. WAL is a way to measure a fund’s potential sensitivity to credit spread changes. WAL is subject to change and may have changed since the date specified.

MANAGER’S DISCUSSION

The Fund’s fiscal year that ended January 31, 2019, was characterized by steadily rising interest rates. The fiscal year began with the target range on the federal funds rate set by the U.S. Federal Reserve (the Fed) at 1.25% to 1.50%. The Fed raised the target range by 0.25% four times during the year—in March, June, September, and December—with the resulting federal funds target rate set at 2.25% to 2.50% at the end of the period. In addition to raising interest rates, the Fed also continued to shrink its balance sheet by systematically allowing a portion of the U.S. Treasury and mortgage-backed securities it acquired during its quantitative easing programs to mature without being reinvested. Both the interest rate and balance sheet actions represent steps by the Fed to normalize monetary policy, effectively unwinding the policies it used to assist the economy’s recovery from the financial crisis.

The U.S. economy grew strongly throughout the year. Gross domestic product grew at an average rate of approximately 3.1% on an annualized basis, compared with a solid 2.5% rate for the prior year. The unemployment rate was largely unchanged, ending the fiscal year at 4.0%, down from 4.1% a year earlier. In addition, the underemployment rate, which includes workers marginally attached to the labor force and those working part time for economic reasons, also fell slightly from 8.2% to 8.1% over the same period. Both measures were at or below their lows in the years preceding the financial crisis. These measures, among others, likely gave the Fed the confidence it displayed in moving to normalize interest rates and its balance sheet.

Interest rates on all categories of government money market securities moved gradually higher throughout the year, consistent with the Fed’s moves. The 3-month Treasury bill (T-bill) yields averaged 1.58% during February 2018, the first month of the fiscal year; 2.40% during January 2019, the last month of the fiscal year; and 2.04% on average for the entire fiscal year. This compares with an average of 1.01% for the year that ended January 31, 2018. Similarly, average 6-month T-bill yields were 1.77% in February 2018; 2.50% in January 2019; and 2.21% over the whole fiscal year, up from an average of 1.14% in the previous fiscal year. The higher yields on T-bills were due not only to the Fed’s interest rate hikes but also to an increased supply of T-bills from the U.S. Treasury, which needed to finance the growing U.S. federal deficit. The total amount of T-bills outstanding grew from $1.964 trillion at the beginning of the fiscal year to $2.289 trillion at the end.

The yields on repurchase agreements (repos) generally followed the same path and were also heavily influenced by the Fed’s decisions. Overnight Treasury repo rates, as measured by the Fed’s Tri-Party General Collateral Rate, averaged 1.31% in February 2018, the fiscal year’s first month, and 2.44% in January 2019, the fiscal year’s last month. For the entire fiscal year that ended January 31, 2019, the average Treasury repo yield was 1.92%, up from 0.94% for the previous fiscal year.

Our investment strategy remained consistent throughout the year. We invested in T-bills and U.S. Treasury notes— including floating-rate notes—as well as repos collateralized by Treasury securities, while taking into account the Fund’s overall level of liquidity and average maturity.

Strategic outlook

The economy has continued its solid performance, with a consistently strong labor market and gradually rising—but still below target—inflation. At the end of the fiscal year, the Fed signaled that it will proceed more cautiously, weighing incoming economic data and other factors and modifying its interest rate path accordingly. As the Fed is no longer projecting further gradual increases in interest rates and is instead espousing patience, the interest rate outlook as the fiscal year begins is for steady rates, and the direction of the next move in interest rates will depend on the evolution of the economy. The fiscal impulse from the federal tax cut that helped boost the economy over the past year may fade somewhat, potentially leading to slower economic growth over the following year. These factors suggest that interest rates on U.S. government money market securities may be little changed for at least the early part of the fiscal year. The risks to this outlook appear to be roughly balanced, as a still-strong economy could eventually call for higher rates, while rates could fall if the economy weakens due to a variety of factors, such as political developments in both the U.S. and abroad; a pullback in risk asset valuations; and a turn in the economic cycle, as the current expansion is well aged by historical standards. In the face of this uncertainty, we believe that our investment strategy, with its focus on capital preservation and liquidity, should enable the Fund to continue to meet its objectives.

Fund expenses (unaudited) Wells Fargo Treasury Plus Money Market Fund 9

As a shareholder of the Fund, you incur ongoing costs, including management fees, distribution (12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from August 1, 2018 to January 31, 2019.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

¹ Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect the one-half-year period).

20 Wells Fargo Treasury Plus Money Market Fund Notes to financial statements

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Treasury Plus Money Market Fund (the “Fund”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

As permitted under Rule 2a-7 of the 1940 Act, portfolio securities are valued at amortized cost, which approximates fair value. The amortized cost method involves valuing a security at its cost, plus accretion of discount or minus amortization of premium over the period until maturity.

Investments which are not valued using the method discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Fund. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Repurchase agreements

The Fund may invest in repurchase agreements and may participate in pooled repurchase agreement transactions with other funds advised by Funds Management. Repurchase agreements are agreements where the seller of a security to the Fund agrees to repurchase that security from the Fund at a mutually agreed upon time and price. The repurchase agreements must be fully collateralized based on values that are marked-to-market daily. The collateral may be held by an agent bank under a tri-party agreement. It is the custodian’s responsibility to value collateral daily and to take action to obtain additional collateral as necessary to maintain a market value equal to or greater than the resale price. The repurchase agreements are collateralized by securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities. There could be potential loss to the Fund in the event that the Fund is delayed or prevented from exercising its rights to dispose of the collateral, including the risk of a possible decline in the value of the underlying obligations during the period in which the Fund seeks to assert its rights.

When-issued transactions

The Fund may purchase securities on a forward commitment or when-issued basis. The Fund records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Fund’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis are marked-to-market daily and the Fund begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed on non-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed from non-accrual status.

Notes to financial statements Wells Fargo Treasury Plus Money Market Fund 21

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of January 31, 2019, the cost of investments for federal income tax purposes is substantially the same as for financial reporting purposes.

Class allocations

The separate classes of shares offered by the Fund differ principally in distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Fund’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Fund’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities as of January 31, 2019:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
Assets
Investments in:
Repurchase agreements	$	0	$	9,504,216,000	$	0	$	9,504,216,000
Treasury debt		0		5,727,438,410		0		5,727,438,410
Total assets	$	0	$	15,231,654,410	$	0	$	15,231,654,410

Additional sector, industry or geographic detail is included in the Portfolio of Investments.

At January 31, 2019, the Fund did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As compensation for its services under the investment management agreement, Funds Management is entitled to receive an annual management fee starting at 0.15% and declining to 0.13% as the average daily net assets of the Fund increase. For the year ended January 31, 2019, the management fee was equivalent to an annual rate of 0.14% of the Fund’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Fund. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Fund and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.01% as the average daily net assets of the Fund increase.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent, sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A		0.22	%
Administrator Class		0.10
Institutional Class		0.08
Service Class		0.12
Sweep Class		0.03

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Funds Management has committed through May 31, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.60% for Class A shares, 0.35% for Administrator Class shares, 0.20% for Institutional Class shares, 0.45% for Service Class shares, and 0.83% for Sweep Class shares. Prior to or after the commitment expiration date, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Prior to June 1, 2018, the Fund’s expenses were capped at 0.65% for Class A shares.

Distribution fee

The Trust has adopted a distribution plan for Sweep Class shares of the Fund pursuant to Rule 12b-1 under the 1940 Act. A distribution fee is charged to Sweep Class shares and paid to Wells Fargo Funds Distributor, LLC, the principal underwriter, at an annual rate of 0.35% of the average daily net assets of Sweep Class shares.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Service Class, and Sweep Class of the Fund are charged a fee at an annual rate of 0.25% of the respective average daily net assets of each class. Administrator Class is charged a fee at an annual rate of 0.10% of its average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

Interfund transactions

The Fund may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid was $252,999,389 and $114,341,923 of ordinary income for the years ended January 31, 2019 and January 31, 2018, respectively.

As of January 31, 2019, distributable earnings on a tax basis consisted of $18,737,343 in undistributed ordinary income.

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders under U.S. generally accepted accounting principles. The amounts of distributions to shareholders for the year ended January 31, 2018 were as follows:

	Net investment income		Net realized gains
Class A		$    5,757,833		$  7,685
Administrator Class		532,884		158
Institutional Class		100,053,459		63,379
Service Class		7,920,085		6,202
Sweep Class		237		1

6. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

7. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

24 Wells Fargo Treasury Plus Money Market Fund Report of independent registered public accounting firm

TO THE SHAREHOLDERS OF THE FUND AND BOARD OF TRUSTEES OF WELLS FARGO FUNDS TRUST:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Wells Fargo Treasury Plus Money Market Fund (the Fund), one of the funds constituting Wells Fargo Funds Trust, including the portfolio of investments, as of January 31, 2019, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years in the five-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of January 31, 2019, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of January 31, 2019, by correspondence with the custodian and brokers, or by other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have not been able to determine the specific year that we began serving as the auditor of one or more Wells Fargo Funds investment companies, however we are aware that we have served as the auditor of one or more Wells Fargo Funds investment companies since at least 1955.
