Item 5.04 Temporary Suspension of Trading Under Registrant's Employee Benefit

Plans.

On June 19, 2021, Navistar International Corporation ("Navistar") received a notice required by Section 101(i)(2)(E) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), regarding a blackout period under each of the Navistar, Inc. Retirement Accumulation Plan and the Navistar, Inc. 401(k) Plan for Represented Employees (collectively, the "Plans"). The blackout period for the Plans is being implemented in connection with the anticipated closing of the previously-announced merger of Dusk Inc. (the "Merger Subsidiary"), a wholly owned indirect subsidiary of TRATON SE, with and into Navistar (the "Merger") with Navistar continuing as the surviving corporation and an indirect subsidiary of TRATON SE following the consummation of the Merger, pursuant to an Agreement and Plan of Merger, dated as of November 7, 2020, among Navistar, TRATON SE and the Merger Subsidiary (the "Merger Agreement").

The blackout period is required to facilitate the elimination of the Navistar International Corporation Common Stock Fund (the "Navistar Stock Fund") as an investment option under each of the Plans, and the liquidation of shares of Navistar common stock currently held in the Plans as a result of the Merger. The blackout period is necessary to ensure that all transactions relating to the Navistar Stock Fund under each of the Plans are fully completed before the Effective Time (as defined in the Merger Agreement) of the Merger and the administrators of each of the Plans can process the receipt of the cash consideration in the Merger in exchange for the Navistar common stock.

The consummation of the Merger remains subject to regulatory approvals and the satisfaction of customary closing conditions set forth in the Merger Agreement.

Participants in the Plans have been advised that there will be a blackout period under the Plans that is expected to begin as of 1:00pm (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 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. Because the actual closing date of the Merger is not certain at this time, Navistar is unable to determine the exact dates for the Blackout Period. Further, the duration of the Blackout Period could change, be advanced or be extended. During the Blackout Period, participants in the Plans will be unable to sell or diversify assets held in the Navistar Stock Fund, add or direct assets to the Navistar Stock Fund and/or take withdrawals, loans or distributions from the portion of their accounts invested in the Navistar Stock Fund. Participants will not be restricted from directing or diversifying investments in the existing account balances in the Plans that do not involve the Navistar Stock Fund.

As a result of the foregoing, on June 19, 2021, in accordance with Section 306 of the Sarbanes-Oxley Act of 2002 and Regulation BTR as promulgated by the Securities and Exchange Commission, Navistar sent a separate notice (the "Notice") to its directors and executive officers informing them of the Blackout Period and certain trading prohibitions that they will be subject to during the Blackout Period with respect to shares of Navistar common stock.

Before and during the Blackout Period and for a period of two years after the end date thereof, inquiries concerning the Blackout Period, including the beginning and ending dates of the trading restrictions, may be directed without charge to:
