Form of Relative PU Award Notice 2019 (Share Settled)

Dear /$ParticipantName$/ :

The Compensation Committee (the “Committee”) of the Board of Directors of Knight-Swift Transportation Holdings Inc. (the “Company”) has awarded you, as of the date of this letter (the “Grant Date”), a relative performance unit grant (the “Grant”). The Grant entitles you to receive shares of the Company’s Class A common stock (the “Stock”), par value $0.01 per share (the “Stock Award”), to be issued upon the completion of the Vesting Period. This Grant is made subject to the terms and conditions of this Relative Performance Unit Grant Agreement (this “Agreement”), and the Company’s Amended and Restated 2014 Omnibus Incentive Plan, as amended (the “Plan”). In this Agreement, the Company is sometimes referred to as “we” or “us” and includes any subsidiaries of the Company in which the Company holds an equity or voting interest of fifty percent (50%) or more. Terms used in this Agreement that are defined in the Plan have the same meaning as stated in the Plan.

1.Summary of Grant.

Your tentative award of Relative Performance Units (the “Tentative Award”) is determined by dividing the dollar award amount the Committee establishes for you by the market value of the Company’s Stock as of the Grant Date. At the end of the Performance Period, your Tentative Award will be adjusted according to the Company’s performance of its Compound Annual Revenue Growth Rate (CAGR) and Return On Net Tangible Assets (RONTA), each measured from the beginning to the end of the Performance Period relative to a peer group consisting of seven (7) other trucking companies identified in Exhibit A, attached hereto with a comparable business focus to the Company, measured over the same period. Each of the eight companies (the Company plus its seven peer companies) will be ranked separately according to CAGR and RONTA from highest to lowest at the end of the Performance Period. After the rankings are complete, your Tentative Award is multiplied by the percentage shown at the intersection of the two CAGR and RONTA rankings on the Relative Performance Matrix, attached hereto as Exhibit A. This is your Pre-Peer Adjustment Award. Your Pre-Peer Adjustment Award will be increased by up to 25%, if the total compounded annual shareholder return on the Company’s Stock (“TSR”), exceeds the 75^th percentile of the Company’s TSR Leverage Award Peer Group set forth in Exhibit B. The TSR for the Company and for any peer will be determined by comparing the rate of growth of the average stock price of each company for the 60 trading days on and following the Grant Date, to the average stock price of each company for the final 60 trading days of the Performance Period, assuming that dividends are reinvested at the closing stock price of the applicable stock on the date the dividend is declared. Conversely, your Pre-Peer Adjustment Award will be decreased by up to 25%, if the relative compounded TSR, is below the 40^th percentile of the Company’s TSR Leverage Award Peer Group. The increase or decrease of performance units granted in your Pre-Peer Adjustment Award is determined by multiplying the TSR Award Leverage Factor set forth in Exhibit B by your Pre-Peer Adjustment Award under the methodology described here. The product is your final award (the “Final Award”).

2.Vesting and Proration of Award.

(a)    Vesting and Payment. Performance units representing your Final Award will not vest until the January 31 following the expiration of the Performance Period (the “Vesting Period”).

(b)    Death, or Disability. If during the Vesting Period or Performance Period, you die, or become disabled, you will be fully vested. The Final Award will be made to you as soon as practicable after the close of the calendar year in which you died, or became disabled, but not later than the 75^th day after the close of such calendar year.

(c)    Change in Control. If during the Vesting Period, there is both (i) a Change in Control, and (ii) your employment terminates by reason of Termination for Convenience or Termination for Good Reason (as defined below) before the January 31 following the expiration of the Performance Period, you will be fully vested. If during the Performance Period, there is both (i) a Change in Control, and (ii) your employment terminates by reason of Termination for Convenience or Termination for Good Reason within 12 months of the Change in Control, then you will be fully vested, and your Final Award will be measured based on the Company’s performance through the end of the calendar year in which your employment terminated. If your

employment terminates by reason of Termination for Convenience or Termination for Good Reason more than 12 months after a Change in Control, then your award will be prorated if all applicable conditions in Section 2(d) are met.

(d)    Forfeiture; Proration. If your employment terminates by reason of Termination for Convenience or Termination for Good Reason (as defined below), your award will be forfeited if you have completed less than 12 calendar months of the Performance Period at the time of termination. If you have completed 12 calendar months or more of the Performance Period, and your employment terminates by reason of Termination for Convenience or Termination for Good Reason, the amount of your Final Award will be pro-rated by multiplying the number of performance units identified in your Final Award as of expiration of the Performance Period by a fraction, the numerator of which is the number of full calendar months credited to you from the start of the Performance Period to the date your Termination for Convenience or Termination for Good Reason occurs, and the denominator of which is 36 months.

3.Issuance of Stock. Subject to Section 2 concerning time for payment, once your Final Award is vested, the Company will issue Stock to you in an amount equal to the number of performance units earned as your Final Award. No Stock will be issued to you until your Final Award is fully vested and earned. The Stock is subject to the conditions of this Agreement. Until Stock is issued to you, you will receive no dividends and will not be entitled to vote at any shareholder meeting. Upon the issuance of Stock to you, the performance units granted to you in the Final Award will settled and be cancelled.

4.Grant of Relative Performance Units. This Grant relates only to the Performance Period specified above and to no other. The Grant is made to you as part of your compensation and is payable to you in accordance with this Agreement and resolutions adopted by the Committee, and in the expectation that until such time as this Grant is fully vested, you will continue to perform services for the Company as its employee. You will receive no fractional shares of Stock. Unless the Committee determines otherwise, this Grant may not be settled in cash. The number of shares of your Stock Award is subject to automatic adjustment for stock dividends, stock splits, reverse stock splits, reorganizations, or reclassifications as provided in Section 6.2 of the Plan and is subject to adjustment as described in Section 1, above.

5.Book Entry Form. To receive your Stock Award, you must open a personal brokerage account with Merrill Lynch or the Company’s then current equity plan administrator. The Stock will be issued to you at the conclusion of the Vesting Period by delivering it to your brokerage account with Merrill Lynch or the Company’s then current equity plan administrator in book entry (non-certificated) form. Stock will be treated as issued and outstanding only after it is actually issued. Any Stock issued is subject to other limitations as either the Plan or the law may require.

6.Tax Treatment. You will recognize ordinary income for the value of the Stock issued to you, as the Stock Award vests. The value of the Stock is its fair market value, which is based on the closing market price the day the Stock Award vests. If the vesting date falls on a weekend or on a holiday, the fair market value will be based on the closing market price of the business day immediately prior to the day of vesting. By accepting the Grant, you accept responsibility for any

income tax withholding or other taxes imposed on you by virtue of the issuance of the Grant. You agree that the Company has the right, and you authorize the Company to reduce the number of shares of Stock distributed to you, by the amount of any federal or state taxes (including, without limitation, FICA, FUTA, and Medicare) the Company is obligated to withhold and pay.

7.Noncompete and Non-Solicitation Agreement.

(a)    This Grant has been made to you because you have been retained by the Company in a position of trust and confidence and your services are important to the Company’s success and not easily replaceable. This Grant is also intended to induce you to continue to contribute to the results of the Company’s operations. In consideration for the issuance of this Grant (and the Company’s agreement to allow you to become a shareholder of the Company on the terms set forth herein), you agree that you will not directly compete with the Company for six (6) months after your Separation from Service (as defined in the Plan) (the “Noncompete Period”), without first obtaining the Company’s prior written consent, which consent the Company may, in its reasonable discretion, withhold. For this purpose, you will be considered to be directly competing with the Company if you are engaged in any of the activities described in clauses (b)(i), (ii) or (iii) below. The consideration for this six (6) month noncompete agreement is the issuance of this Grant.

(b)    You will be considered to be directly competing with the Company if at any time during the Noncompete Period you: (i) are employed by, contract with, or obtain an interest as an owner, shareholder, partner, limited partner or member in, any business or corporation that competes directly with the Company (as such direct competition is defined below), but excluding an investment of one percent (1%) or less in any publicly traded company; (ii) on your own behalf, or on behalf of any other person with whom you are employed, you solicit or divert from the Company the business of any person who is either a customer of the Company during your employment, or is identified as a potential customer of the Company; or (iii) solicit, divert or encourage any person who is an employee of the Company to leave employment and to become employed by a person who directly competes with the Company. For purposes of this Section 7, you (x) will be considered to be in direct competition with the Company and (y) a person, business or corporation will be considered a direct competitor of the Company, if either you or it is engaged in a truckload business (dry van, refrigerated, brokerage, drayage, intermodal, or logistics or any combination thereof) that conducts significant operations in the same traffic lanes in which the Company operates, or which the Company has internally identified as a planned area of operation or expansion of its business as of the date of your Separation from Service with the Company.

(c)    By accepting this Grant, you agree that the foregoing non-competition provisions are reasonable and that you are being compensated for your agreement not to compete.

(d)    The Company shall have the right to extend the Noncompete Period for up to an additional 12 months beyond the completion of your initial Noncompete Period (the “Extended Noncompete Period”). If the Company elects to extend the Noncompete Period, it will notify you in writing of such fact not later than the thirtieth (30th) day prior to the expiration of the initial Noncompete Period. By accepting this Grant, you agree to accept and abide by the Company’s election. If the Company elects to extend the Noncompete Period, you agree not to work for any

direct competitor of the Company (as defined in Section 7(b)) during the Extended Noncompete Period, and the Company agrees to pay you, during the Extended Noncompete Period, an amount equal to your monthly base salary or monthly base consulting fee, as applicable, in effect as of the date of your Separation from Service. Payment for any partial month will be prorated. Payment of your base salary or consulting fee during the Extended Noncompete Period will be made at the same times and in the same amounts that such amounts were paid to you while you were in the service of the Company. If the Company elects to extend the Noncompete Period, any monies you earn from any other work, whether as an employee or as an independent contractor, will reduce, dollar for dollar, but not below zero, the amount that the Company is obligated to pay you. Payments made by the Company under this Section 7(d) are made for the extension of the noncompete covenant and do not render you either an employee of, or a consultant to, the Company.

8.Compliance with Securities Laws; Share Restrictions.

(a)    So long as you are an employee of the Company, you may not sell any shares of the Stock except in accordance with all applicable federal and state securities laws and the applicable policies of the Company regarding the sale, ownership and retention of the Company’s securities by insiders, executives, and employees. The Company has filed a registration statement with the United States Securities and Exchange Commission covering the Grant (and the Stock subject to the Grant) issued pursuant to the Plan. So long as that registration statement is in effect, Stock issued pursuant to the Plan will not be restricted as to transfer. The Company does not provide any assurance that any registration statement will continue to be maintained in effect with respect to the Stock. If for any reason, a registration statement is not in effect with respect to the Stock, the Stock may not be sold or transferred except in compliance with applicable securities laws.

(b)    This Grant is subject to any claw-back policy adopted by the Company for incentive-based compensation (the “Clawback Policy”), as required by Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Clawback Policy, as in existence from time to time, is incorporated by this reference into this Agreement. If there is any conflict between the provisions of this Agreement and the Clawback Policy, the Clawback Policy shall control.

9.Risks. By accepting this Grant, you acknowledge that the value of the Stock may be adversely affected by changes in the United States’ economy; changes in the Company’s profitability, financial condition, business or properties; a reduction in the Company’s growth rate; competition from other truckload carriers; and other factors that are described more particularly in the Company’s most recent Annual Report on Form 10-K and in its reports on Forms 10-Q and 8-K. The Company does not promise you that the value of the Stock will rise or that the Company will continue to grow or be profitable.

In the event that the selected arbitrator(s) finds any term or clause in this Agreement to be invalid, unenforceable, or illegal, the same will not affect any other terms or clauses in the Agreement or the entire Agreement. The Company shall pay the costs of arbitration, but if the Company is the prevailing party in the arbitration, the Company shall have the right to recover from you all costs of arbitration.

In the event of any conflict between the arbitration procedures specified in this Agreement and the RAAA, this Agreement shall control.
