Report of Independent Registered Public Accounting Firm

To the Benefits Administration Committee of U.S. Bancorp and Participants of the U.S. Bank 401(k) Savings Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the U.S. Bank 401(k) Savings Plan (the Plan) as of December 31, 2019 and 2018, and the related statements of changes in net assets available for benefits for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2019 and 2018, and the changes in its net assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements 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 Plan 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 are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, 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. 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. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Schedule

The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2019, has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The information in the supplemental schedule is the responsibility of the Plan’s management. Our audit procedures included determining whether the information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the information, we evaluated whether such information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the information is fairly stated, in all material respects, in relation to the financial statements as a whole.

1. Description of the Plan

The following description of the U.S. Bank 401(k) Savings Plan (the “Plan”) provides only general information. Participants should refer to the Plan’s Summary Plan Description (the “SPD”) and plan prospectus for a more complete description of the Plan’s provisions. The SPD and plan prospectus can be reviewed by visiting www.usbank.com/benefitsandrewards.

Administration and Participation

The Plan is a defined contribution retirement plan covering substantially all employees of U.S. Bancorp (the “Company”, the “Plan Sponsor”, and the “Plan Administrator”) and its subsidiaries. Employees are eligible to participate in the Plan on their hire date so long as they are a regular, permanent employee working in an eligible position. Eligible employees are automatically enrolled in the Plan with a before-tax salary deferral of 2 percent of eligible compensation, unless the employee elects otherwise.

Each participant’s account is credited with applicable participant contributions, rollovers, employer contributions, and an allocation of the earnings (losses) of the investment funds in which the participant has elected to invest. Earnings (losses) allocations are based upon the participant account balance, as defined in the Plan document. In addition, applicable participant distributions and loans as well as an allocation of administrative expenses are charged to each participant’s account. Participants may invest their account balance in one or more of a variety of investment funds and are immediately 100 percent vested in their entire account balance.

The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the Internal Revenue Code (the “Code”).

The Plan is administered by the Company’s Benefits Administration Committee and has investment oversight by the Investment Committee.

1. Description of the Plan (continued)

Contributions

The Plan permits before-tax and after-tax (“Roth”) elective contributions up to a combined maximum of 75 percent of a participant’s eligible compensation, subject to the Internal Revenue Service (the “IRS”) limit. Participants age 50 and older whose elective contributions have reached the IRS limit are permitted under the Plan to make before-tax and Roth catch-up contributions up to the IRS catch-up limit. All participant contributions were deposited into the Plan bi-weekly.

The Company makes a matching contribution equal to 100 percent of each participant’s contribution up to 4 percent of their annual eligible compensation. A participant becomes eligible for an employer matching contribution on the first day of the month following completion of one full year of service in which the participant has been credited with working at least 1,000 hours. The employer matching contribution is deposited in the Plan annually and is initially invested in eligible participants’ accounts based on their future contribution investment election. Participants can subsequently change how their matching contributions are invested at any time. The employer contribution receivable represents the Company’s matching contribution for 2019, which was deposited in the Plan in January 2020.

Distributions to Participants

The forms of distribution offered by the Plan are a partial or total lump sum payment.

Participant Loans

The Plan contains provisions allowing participants to borrow from their accounts. The minimum loan is $1,000 and the maximum is the lesser of 50 percent of the participant’s account balance or $50,000 minus the participant’s highest outstanding loan balance during the past 12 months. Each loan bears interest at 1 percent above the prime interest rate at the date of issuance as determined monthly by the Plan Administrator. Principal and interest are repaid ratably through bi-weekly payroll deductions. Beginning January 1, 2018, participants may have no more than one outstanding loan at any time.

Plan Investments

The Plan offers a diversified selection of investments intended to satisfy ERISA requirements. Participants also have the option of investing in mutual funds in a self-directed brokerage account. The Plan includes an employee stock ownership plan (“ESOP”) fund. All participant and employer matching contributions credited to a participant’s account that are invested in qualifying employer securities are invested in the ESOP fund. The primary purpose of the ESOP fund is to benefit participants and beneficiaries by obtaining and retaining for them a position of equity ownership in the Company. Dividends paid on qualifying employer securities held in the ESOP are either reinvested in the ESOP or paid directly to the participant, per their election.

Plan Termination

Although it has not expressed any intention to do so, the Company has the right to suspend or terminate the Plan at any time by action of its Board of Directors subject to the provisions of ERISA. In the event of a termination of the Plan, all participant account balances remain fully vested and are eligible for distribution.

2. Significant Accounting Policies

Accounting Method

The financial statements of the Plan are prepared using the accrual method of accounting under U.S. generally accepted accounting principles.

Investment Valuation and Income Recognition

Investments held by a defined contribution retirement plan are required to be reported at fair value, except for fully benefit-responsive investment contracts. For the portion of the net assets available for benefits attributable to fully benefit-responsive investment contracts, contract value is the relevant measure because it is the amount participants normally would receive if they were to initiate permitted transactions under the terms of the Plan. See Note 4 for a discussion of fair value measurements.

6

U.S. Bank 401(k) Savings Plan

Notes to Financial Statements (continued)

2. Significant Accounting Policies (continued)

Purchases and sales of securities are recorded on a trade-date basis. If a trade is open at the end of the year, a receivable for securities sold but not yet settled or a payable for securities purchased but not yet settled is reflected in the Statement of Net Assets Available for Benefits.

Dividends are recorded on the ex-dividend date.

Brokers’ commissions and other expenses incurred upon the purchase of corporate stock are included in the cost of the corporate stock. Brokers’ commissions and other expenses incurred upon the sale of corporate stock are reflected as a reduction in the proceeds from the sale.

The change from the beginning to the end of the year in the difference between fair value and the cost of investments is reflected in the Statement of Changes in Net Assets Available for Benefits as net appreciation or depreciation in fair value of investments.

The net gain (loss) on sales of investments is the difference between the proceeds received and the average cost of investments sold and is also reflected in the Statement of Changes in Net Assets Available for Benefits in net appreciation or depreciation in fair value of investments.

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. If a participant ceases to make loan payments and the Plan Sponsor deems the loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded. Accordingly, no allowance for credit losses has been recorded as of December 31, 2019 or 2018.

Administrative Expenses

Recordkeeping, investment management, trust, consulting, audit, and other administrative fees are paid by the Plan and are recorded as administrative expenses as incurred.

Payment of Benefits

Benefit payments are recorded when paid.

2. Significant Accounting Policies (continued)

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements, accompanying notes and supplemental schedule. Actual results could differ from those estimates and assumptions.

Risks and Uncertainties

The Plan’s investments are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the values of investments, it is at least reasonably possible that changes in risks in the near term could materially affect participants’ account balances and the amounts reported in the Statement of Net Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits.

3. Stable Value Fund

The Plan offers a stable value investment option, the U.S. Bank Stable Value Fund (the “Fund”). The Fund invests in fully benefit-responsive investment contracts, including synthetic guaranteed investment contracts (“GIC”) and a separate account GIC issued by insurance companies which consists of insurance and wrapper contracts, and short-term investments. These investments are reported at contract value. The following table disaggregates contract value between the types of investment contracts held by the Plan:

8

U.S. Bank 401(k) Savings Plan

Notes to Financial Statements (continued)

3. Stable Value Fund (continued)

The synthetic GICs consist of two parts: an underlying investment owned directly by the Plan and a wrapper contract purchased from an insurance company. The wrapper contract guarantees full payment of principal and interest. The wrapper contract amortizes realized and unrealized gains and losses on the underlying fixed income investments, typically over the duration of the investments, through adjustments to the future interest crediting rate. These investments are credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses.

The separate account GIC is an investment in a segregated account of assets maintained by an insurance company for the benefit of the investors. The total return of the segregated account assets supports the separate account GIC return.

The Plan’s ability to receive amounts due in accordance with the fully benefit-responsive investment contracts is dependent on the third-party issuers’ ability to meet their financial obligations. The issuers’ ability to meet its contractual obligations may be affected by future economic and regulatory developments.

Certain events may limit the ability of the Plan to transact at contract value with the contract issuer. Examples of such events include the following:

9

U.S. Bank 401(k) Savings Plan

Notes to Financial Statements (continued)

3. Stable Value Fund (continued)

At this time, the Plan Sponsor does not believe that the occurrence of any such market value event that would limit the Plan’s ability to transact at contract value with participants is probable.

In addition, certain events allow the issuers to terminate the contracts with the Plan and settle at an amount different from contract value. Those events may be different under each contract. Examples of such events include the following:

The Fund owns units of the Wells Fargo/BlackRock Short-Term Investment Fund S, which serve as the Fund’s short-term liquidity vehicle.

4. Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset (an entry price) or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value measurement reflects all the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance.

The Plan groups its assets measured at fair value into a three-level hierarchy for valuation techniques used to measure financial assets at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are:

10

U.S. Bank 401(k) Savings Plan

Notes to Financial Statements (continued)

4. Fair Value Measurements (continued)

If the Plan were to change its valuation inputs for measuring financial assets at fair value, either due to changes in current market conditions or other factors, it may need to transfer those assets into or out of Level 3 of the hierarchy based on the new inputs used. During the years ended December 31, 2019 and 2018, there were no transfers of financial assets into or out of Level 3 of the hierarchy.

The following section is a description of the valuation techniques and inputs used by the Plan to measure each major class of assets at fair value. During 2019 and 2018, there were no changes to the valuation techniques used by the Plan to measure fair value. There were no unfunded commitments related to these investments for the years ended December 31, 2019 and 2018.

Mutual funds: Valued at the daily closing price as reported by the fund. Mutual funds held by the Plan are open-ended mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily net asset value (“NAV”) and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded.

Corporate stocks: Valued at the last reported sales price of the year in the national security exchange in which the individual securities are traded.

Self-directed brokerage accounts: The investments in the accounts consist solely of mutual funds, which are valued at the daily closing price as reported by the fund. The mutual funds held in the accounts are open-ended mutual funds that are registered with the Securities and Exchange Commission. These funds are required to publish their daily NAV and to transact at that price. The mutual funds held in the accounts are deemed to be actively traded.

Collective investment funds: Valued using the NAV provided by the trustee of the fund. The NAV is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investment held by the fund less its liabilities.

As required by applicable authoritative accounting guidance, the level in the fair value hierarchy within which the fair value measurement of the asset in its entirety is classified is based on the lowest-level input that is significant to the fair value measurement.

The following table summarizes the Plan’s investment assets measured at fair value at December 31:

Notes to Financial Statements (continued)

5. Transactions with Parties in Interest

The Plan allows for transactions with certain parties who may perform services or have fiduciary responsibilities to the Plan. Parties in interest include the Company and U.S. Bank National Association (the “Trustee”). Transactions involving funds administered by the Trustee are considered party-in-interest transactions. These transactions are not considered prohibited transactions under 29 CFR 408(b) of the ERISA regulations.

The Plan invests in the common stock of the Company. At December 31, 2019 and 2018, the Plan held 18,595,689 and 21,413,063 shares, respectively, of U.S. Bancorp common stock. During the years ended December 31, 2019 and 2018, the Plan recorded dividend income from U.S. Bancorp common stock of $31,461,613 and $29,446,859, respectively.

The Plan also invests in a money market mutual fund of First American Funds, Inc., which is managed by the Company.

6. Tax Status

The Plan has received a determination letter from the IRS dated July 13, 2017, stating that the Plan is qualified under Section 401(a) of the Code and therefore, the related trust is exempt from taxation. Subsequent to this determination by the IRS, the Plan was amended. The Plan is required to operate in conformity with the Code to maintain its qualified status. The Plan Administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and therefore, believes the Plan, as amended, is qualified and the related trust is tax-exempt.

Accounting principles generally accepted in the United States require plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the

Plan, and has concluded that as of December 31, 2019, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

7. Subsequent Event

On December 31, 2019 an outbreak of coronavirus disease, subsequently named COVID-19 was first reported from Wuhan, China. On January 30, 2020, this was declared a Public Health Emergency of International Concern by the World Health Organization, with the outbreak spreading internationally over the first quarter of 2020. Beginning in March 2020, the financial markets have experienced volatility due to the COVID-19 pandemic. While the overall impact of the volatility cannot be estimated with any certainty, it appears likely that changes in the valuation of Plan assets will continue to occur. Due to the uncertainty of the financial markets during this time, Plan management is unable to predict the impact of future changes in the risks on the assets of the Plan.
