Plan Administrator and Plan Participants

Navistar, Inc. 401(k) Plan for Represented Employees

Opinion on the financial statements

We have audited the accompanying statements of net assets available for benefits of Navistar, Inc. 401(k) Plan for Represented Employees (the 'Plan') as of December 31, 2020 and 2019, the related statement of changes in net assets available for benefits for the year ended December 31, 2020, 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 as of December 31, 2020 and 2019, and the changes in net assets available for benefits for the year ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America.

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 information

The schedule of assets (held at end of year) as of December 31, 2020 ('supplemental information') has been subjected to audit procedures performed in conjunction with the audit of the Plan's financial statements. The supplemental information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental 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 information. In forming our opinion on the supplemental information, we evaluated whether the supplemental 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 supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

NOTES TO FINANCIAL STATEMENTS

December 31, 2020 and 2019

NOTE A - DESCRIPTION OF THE PLAN

The following description of the Navistar, Inc. 401(k) Plan for Represented Employees (the 'Plan') is provided for general information purposes only. Participants should refer to the Plan document for more complete information.

General

The Plan is sponsored by Navistar, Inc. (the 'Company'), the principal operating subsidiary of Navistar International Corporation ('Navistar'), to provide savings and retirement benefits for certain eligible represented employees of the Company and of certain affiliates participating under the Plan. The Plan was established October 2, 1991; and has subsequently been amended to maintain qualification under Sections 401(a), 401(k) and 501 of the Internal Revenue Code of 1986, as amended (the 'IRC'). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ('ERISA').

In response to the pandemic outbreak of a novel coronavirus (COVID-19), the United States Congress passed the Coronavirus Aid, Relief and Economic Security Act (CARES Act) to provide expanded access to retirement plan accounts. Effective April 23, 2020, the Plan adopted provisions under the CARES Act related to distributions, loans and deferred loan repayments for those participants who qualified under the CARES Act.

Effective November 7, 2020, Navistar and TRATON SE ('TRATON'), the truck and bus unit of Volkswagen AG, reached a definitive merger agreement. TRATON currently owns approximately 17% of Navistar's outstanding shares of common stock. Under the agreement, TRATON will acquire all of Navistar's outstanding common shares that it does not currently own at a price of $44.50 per share. Navistar's shareholders approved the transaction on March 2, 2021. Subject to regulatory approvals and the satisfaction of customary closing conditions, the transaction is expected to be completed in mid-2021.

If the merger closes, all of Navistar common stock held in the Plan's Navistar International Corporation Common Stock Fund ('Navistar Stock Fund') investment option will be purchased for $44.50 per share and the Navistar Stock Fund will then be removed as an investment option in the Plan. On June 19, 2021, as required by section 101(i)(2)(E) of ERISA, the Plan notified Navistar that the Navistar Stock Fund will be permanently frozen and liquidated upon the closing of the merger. Although the actual closing date of the merger is uncertain and the consummation of the merger remains subject to regulatory approvals and the satisfaction of customary closing conditions set forth in the merger agreement, on June 19, 2021, the Plan also notified Navistar that in connection with the anticipated closing of the merger a blackout period is expected to begin at 1:00 p.m. Central Time on June 23, 2021 and end during the week of July 4, 2021 or as soon as administratively possible after the week of July 4, 2021 (the 'Blackout Period'). Although the Blackout Period is expected to end during the week of July 4, 2021, this end date is subject to change, and could be a date that is earlier or later than the week of July 4, 2021. During the Blackout Period, participants will not be able to engage in any transactions involving the Navistar Stock Fund. Any shares held in the Navistar Stock Fund upon the start of the Blackout Period will be converted to cash in conjunction with the merger closing and the participant's share of the cash will be reinvested within the Plan in the respective American Funds Target Date Retirement Series fund based on the participant's birthdate. In addition, after the Blackout Period begins, any investment elections for future contributions (including any loan repayments) in the Navistar Stock Fund will be mapped to the respective American Funds Target Date Retirement Series fund based on the participant's birthdate.

NOTE A - DESCRIPTION OF THE PLAN - Continued

Eligibility

The Plan is offered to eligible Company employees who are represented by a labor organization under a collective bargaining agreement who have met certain seniority or service requirements under the terms of the respective collective bargaining agreements.

Contributions and Vesting

Participant contributions may be made to the Plan on a pretax basis, a Roth basis and/or any combination thereof. Those participants who were age 50 or older during the Plan year are permitted to contribute additional amounts on a pretax and/or Roth basis. Participant contributions may be elected at a minimum level of 1% of eligible compensation at any time. Total participant contributions cannot exceed 25% of the participant's eligible compensation (50% for employees covered under the Main Labor Contract between the Company and the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America, and its affiliated local unions Numbers 6, 119, 402, 472, 658, 1872 and 2293). Participant contributions are limited to a prescribed IRC dollar limit; the additional contributions by participants who were age 50 or older are limited to a separate prescribed IRC dollar limit. Subject to Company approval, certain eligible employees are allowed to make rollover contributions to the Plan if such contributions satisfy applicable regulations. Such employees are not required to be participants for any purpose other than their rollover account; however, no salary reduction contributions may be made until such time as such employee would otherwise become eligible to and does elect participation in the Plan. Participant salary reduction contributions and rollover contributions are fully vested immediately.

New employees are automatically enrolled in the Plan at an employee pretax contribution rate of 6% of eligible compensation. In general, such automatic enrollment will be effective the first pay period following the hire date, unless the employee elects to participate earlier or elects to opt out of enrollment until a future date.

For the 2020 and 2019 Plan years, certain collective bargaining agreements provide for an employer retirement contribution. This contribution is employer-provided and is allocated among eligible members of the applicable bargaining unit based on the participant's age at either year-end, or the calendar quarter end in accordance with the applicable collective bargaining agreement, and eligible compensation. Certain collective bargaining agreements also provide for an employer matching contribution of either 25% of the first 6% of eligible compensation deferred by the participant or 50% of the first 6% of eligible compensation deferred by the participant, as specified in the eligible participant's respective collective bargaining agreement.

Participants vest in the employer retirement and matching contributions credited to their account in accordance with the vesting schedule as set forth in their respective collective bargaining agreement. Non-vested contributions are forfeited when a participant retires or terminates service. Such forfeitures are used to offset future Company contributions. At December 31, 2020 and 2019, forfeited non-vested accounts approximated $535,155 and $108,118, respectively. For the Plan year ended December 31, 2020, $397,963 of forfeitures were used to offset Company contributions.

NOTE A - DESCRIPTION OF THE PLAN - Continued

Investment Options

Participants direct the investment of their account balances and future contributions. Investment options during 2020 and 2019 consisted of funds classified as registered investment companies, collective trusts or Navistar common stock.

Participant Accounts

Individual accounts are maintained for each Plan participant. Realized gains and losses, unrealized appreciation and depreciation, and dividends and interest are allocated to participants based on their proportionate share of the investment funds. Fund managers' fees are charged to participants' accounts as a reduction of the return earned on each investment option. In addition, participant accounts may be assessed a quarterly recordkeeping fee depending on the respective collective bargaining agreement.

Notes Receivable from Participants

Participants may borrow from their fund accounts a minimum of $1,000 up to the lesser of 50% of their pretax, Roth, and rollover account balance or $50,000, with no more than two loans outstanding at a time. Company matching and retirement contributions are not available for loans. Loan transactions are treated as a transfer between the applicable investment funds and the loan fund. Loan terms range from one to five years, with the exception of loans made for the purchase of a principal residence, which may be repaid in installments over a period of up to ten years. The loans are secured by the balance in the participant's account and bear interest at a rate equal to prime as of the date of loan origination, plus one percentage point.

Payment of Benefits

Participants may request either an in-service or hardship withdrawal of certain assets in their account. Participants may only withdraw authorized pretax and Roth salary reduction contributions after attaining age 59 ¹⁄₂, or on a hardship basis prior to attaining age 59 ¹⁄₂. Participants may also withdraw earnings on authorized pretax and Roth salary reduction contributions after attaining age 59 ¹⁄₂, or on a hardship basis prior to attaining age 59 ¹⁄₂. The employer retirement contributions, matching contributions and investment earnings thereon are not eligible for in-service withdrawal.

Navistar, Inc. 401(k) Plan for Represented Employees

NOTES TO FINANCIAL STATEMENTS

December 31, 2020 and 2019

NOTE A - DESCRIPTION OF THE PLAN - Continued

Payment of Benefits - Continued

A participant's vested account is distributable at the time a participant separates from service with the Company, suffers a total and permanent disability or dies. A participant who is on layoff is considered to have terminated employment after the 12-month anniversary of the commencement of the period of continuous layoff. When the participant terminates employment prior to reaching normal retirement age with a vested balance of $5,000 or less, and does not elect to have the distribution paid directly to an eligible retirement plan or receive a distribution, then the balance will be rolled over to an individual retirement plan designated by the Plan administrator.

If the vested balance is more than $5,000, the participant has the option of receiving the account upon separation or deferring commencement until a later date. If the participant elects to receive a check and the check remains uncashed after 120 days, the Plan administrator will notify the participant that the check remains uncashed. Following an administrative period, if the check remains uncashed, the check will be void and the funds will be rolled over to an individual retirement plan designated by the Plan administrator.

If the participant elects to defer commencement, the deferral generally cannot go beyond April 1 of the calendar year following the year in which the participant attains age 72 (or 70 ¹⁄₂ if the participant turned 70 ¹⁄₂ before January 1, 2020) or retires, whichever is later. At that time, the participant must begin to receive a required minimum distribution. Accounts are distributed in a single sum prior to this date, or may be distributed at this date as a lump sum or a required minimum distribution. Accounts may also be distributed as partial lump sums for those who are not subject to a mandatory distribution, subject to rules and limits established by the plan administrator in its discretion.

Administrative Fees

Depending on the respective collective bargaining agreement, certain administrative expenses of the Plan are paid by the Plan and charged to the participants' accounts. All other Plan administrative expenses are paid by the Company and are not reflected in the Plan's financial statements.

December 31, 2020 and 2019

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The financial statements of the Plan are presented on the accrual basis of accounting.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

New Accounting Guidance

In August 2018, the FASB issued ASU 2018-13,Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The ASU modifies the disclosure requirements for the fair value measurements in Topic 820, including the elimination, modification to, and addition of certain disclosures. The ASU is effective for fiscal years beginning after December 15, 2019. The provisions of the ASU did not have a material impact on the Plan's financial statement disclosures.

Risks and Uncertainties

Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements.

Investment Valuation

The Plan follows guidance on accounting for fair value measurements which defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date, and establishes a framework for measuring fair value. The Plan uses a three-level hierarchy of measurements based upon the reliability of observable and unobservable inputs used to arrive at fair value. Observable inputs are independent market data, while unobservable inputs reflect the Plan management's assumptions about valuation. Depending on the inputs, the Plan classifies each fair value measurement as follows:

11

Navistar, Inc. 401(k) Plan for Represented Employees

NOTES TO FINANCIAL STATEMENTS

December 31, 2020 and 2019

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

Investment Valuation - Continued

The following describes the methods and significant assumptions used to estimate fair value of the Plan's investments:

The Plan's interest in the Navistar, Inc. Defined Contribution Plans Master Trust ('Master Trust') is presented at fair value, which has been determined based on the fair value of the underlying investments of the Master Trust.

The investments held by the Master Trust are valued as follows:

Collective trusts: Valued at the net asset value ('NAV') as provided by the administrator of the fund. The NAV is generally based on the fair value of the underlying assets owned by the fund, minus its liabilities, divided by the number of shares outstanding. As of December 31, 2020, collective trusts are classified as Level 2. As of December 31, 2019, collective trusts that invest in assets with observable inputs that reflect quoted prices in an active market are classified as Level 1 and all other collective trusts are classified as Level 2.

Registered investment companies (mutual funds): Valued at the NAV of shares held by the Plan at year end, which is obtained from an active market.

Common stock: Valued at the closing price reported on the active market on which the security is traded.

See Note C - Master Trust for the Master Trust's investments by level within the fair value hierarchy as of December 31, 2020 and 2019.

Notes Receivable from Participants

Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Interest income is recorded on the accrual basis. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2020 or 2019. If a participant ceases to make loan repayments and the Plan administrator deems the participant loan to be in default, the participant loan balance is reduced and a benefit payment is recorded.

NOTES TO FINANCIAL STATEMENTS

December 31, 2020 and 2019

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

Income Recognition

Security transactions are accounted for on the trade-date basis. Dividend income is accrued on the ex-dividend date. Interest income is recorded on the accrual basis. Net realized and unrealized appreciation (depreciation), along with dividend income and interest income (excluding notes receivables from participants) are recorded in the accompanying statement of changes in net assets available for benefits as change in Plan's interest in Master Trust.

Participant Withdrawals

As of December 31, 2020 and 2019, there were no benefits due to former participants who have withdrawn from participation in the Plan. Benefits are recorded when paid.

Transfers

Transfers between the Plan and the Navistar, Inc. Retirement Accumulation Plan which participates in the Master Trust occur when a participant incurs a change in job status or a job transfer to another affiliate that makes the participant ineligible to participate in their current plan and requires the transfer of their account balance to another plan within the Master Trust for which they are eligible. Net transfers from the Plan for 2020 are $640,209.

NOTE C - MASTER TRUST

Great West Trust Company, LLC (the 'Trustee') is the trustee for the Plan. All of the Plan's investment assets are held in a trust account at the Trustee and consist of a divided interest in an investment account of the Master Trust, a master trust established by the Company and administered by the Trustee. Use of the Master Trust permits the commingling of Plan assets with the assets of another defined contribution plan sponsored by the Company and its affiliated companies for investment and administrative purposes. Although assets of the plans are commingled in the Master Trust, the Trustee maintains supporting records for the purpose of allocating the net gain or loss of the investment account to the participating plans. The net investment income or loss of the investment assets is allocated by the Trustee to each participating plan based on the relationship of the interest of each plan to the total of the interests of the participating plans.

The collective trusts generally provide daily redemption with written notice with the exception of the JPMCB Stable Asset Income Fund (the 'JPMCB Fund') valued at $159,204,270 and $129,163,221 as of December 31, 2020 and 2019, respectively. Participants can ordinarily direct the withdrawal or transfer of all or a portion of their investment in the JPMCB Fund at contract value. Certain events may limit the JPMCB Fund's ability to transact at contract value. Such events may include plan termination, bankruptcy and other events outside the normal operation of the JPMCB Fund that may cause a withdrawal which results in a negative market value adjustment. The Plan may terminate its interest in the JPMCB Fund at any time. However, requests received for complete or partial withdrawals must be given in writing not less than 30 days prior to the valuation date, upon which the withdrawal is to be effected, and such withdrawals shall be paid at the lesser of book or market value, as determined by the JPMCB Fund.

NOTE D - TAX STATUS OF THE PLAN

The Plan obtained a determination letter dated September 29, 2016, in which the Internal Revenue Service ('IRS') stated that the Plan, as then designed, was in compliance with the applicable requirements of the IRC. The Plan has been amended since receiving the determination letter. However, the Plan administrator believes that the Plan is currently designed and being operated, in all material respects, in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been included in the Plan's financial statements.

The Master Trust obtained a determination letter dated May 30, 2014, in which the IRS stated that the Trust, as then designed, was in compliance with the applicable requirements of the IRC. The Master Trust has been amended since receiving the determination letter. However, the Plan administrator believes that the Master Trust is currently designed and being operated, in all material respects, in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes related to the Master Trust is included in the Plan's financial statements.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan,

15

Navistar, Inc. 401(k) Plan for Represented Employees

NOTES TO FINANCIAL STATEMENTS

December 31, 2020 and 2019

NOTE D - TAX STATUS OF THE PLAN - Continued

and has concluded that as of December 31, 2020 and 2019, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by the IRS; however, there are currently no audits for any tax periods in progress.

NOTE E - PLAN TERMINATION

Although the Company expects to continue the Plan indefinitely, subject to collective bargaining requirements the Company, at its discretion, reserves the right to amend, modify, suspend or terminate the Plan, provided that no such action shall deprive any person of any rights to contributions made under the Plan. If the Plan is terminated, or contributions thereto have been completely discontinued, the rights of all participants to the amounts credited to their accounts shall be non-forfeitable and the interest of each participant in the funds will be distributed to such participant or his or her beneficiary at the time prescribed by the Plan terms and ERISA. If the Plan is terminated, Plan participants will become fully vested in any funds allocated to them.

NOTE F - RELATED-PARTY TRANSACTIONS

Empower Retirement, an affiliate of the Trustee, is the record keeper as defined by the Master Trust and, therefore, transactions with Empower Retirement qualify as party-in-interest transactions. Also qualifying as party-in-interest transactions are transactions relating to notes receivable from participants and Navistar common stock. As of December 31, 2020 and 2019, respectively, the Master Trust held 619,262 and 1,175,061 shares of Navistar common stock, respectively, valued at $27,222,737 and $34,006,264. Fees paid by the Plan for the investment management services are computed as a basis point reduction of the return earned on each investment option and are included in the net losses of the Master Trust.

NOTE G - SUBSEQUENT EVENTS

Management of the Plan has evaluated subsequent events from December 31, 2020 through the date these financial statements were issued. Other than previously disclosed in Note A, there were no subsequent events that require recognition or additional disclosure in these financial statements.
