Ladies and Gentlemen:

The undersigned hereby tenders to P.A.M. Transportation Services, Inc., a Delaware corporation (the “Company”), at the price per share indicated in this Notice of Guaranteed Delivery, on the terms and subject to the conditions set forth in the Offer to Purchase dated July 27, 2021 (the “Offer to Purchase”), and the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the “Offer”), receipt of which is hereby acknowledged, the number of shares set forth below, all pursuant to the guaranteed delivery procedures set forth in Section 3 of the Offer to Purchase. Unless the context otherwise requires, all references to the shares shall refer to the common stock of the Company.

Number of Shares to be tendered (on a post-split basis): shares*.

The undersigned understands that the number of shares tendered will be deemed to be on a post-stock split basis as a result of the Company’s previously announced 2-for-1 forward split of its common stock in the form of a 100% stock dividend payable on August 16, 2021, to stockholders of record on July 30, 2021, and thus no adjustment will be made to the number of tendered shares. Therefore, the undersigned represents that the specified number of shares to be tendered is on a post-stock split basis. See Instruction 2 of the Letter of Transmittal.

THE UNDERSIGNED IS TENDERING SHARES AS FOLLOWS (CHECK ONLY ONE BOX):

(1) SHARES TENDERED AT PRICE DETERMINED BY STOCKHOLDER (SEE INSTRUCTION 5 OF THE LETTER OF TRANSMITTAL)

By checking ONE of the following boxes below INSTEAD OF THE BOX BELOW UNDER “(2) Shares Tendered at Price Determined Under the Offer,” the undersigned hereby tenders shares at the price checked. This action could result in none of the shares being purchased if the purchase price determined by the Company for the shares is less than the price checked below. A STOCKHOLDER WHO DESIRES TO TENDER SHARES AT MORE THAN ONE PRICE MUST COMPLETE A SEPARATE NOTICE OF GUARANTEED DELIVERY AND/OR LETTER OF TRANSMITTAL FOR EACH PRICE AT WHICH SHARES ARE TENDERED. The same shares cannot be tendered, unless previously properly withdrawn as provided in Section 4 of the Offer to Purchase, at more than one price.

PRICE (IN DOLLARS) PER SHARE AT WHICH SHARES
ARE BEING TENDERED (ON A POST-SPLIT BASIS)

☐ $32.00

☐ $33.00

☐ $34.00

☐ $35.00

☐ $36.00

☐ $37.00

☐ $32.50

☐ $33.50

☐ $34.50

☐ $35.50

☐ $36.50

(2) SHARES TENDERED AT PRICE DETERMINED UNDER THE OFFER (SEE INSTRUCTION 5 OF THE LETTER OF TRANSMITTAL)

By checking the box below INSTEAD OF ONE OF THE BOXES ABOVE UNDER “(1) Shares Tendered at Price Determined by Stockholder,” the undersigned hereby tenders shares at the purchase price, as the same shall be determined by the Company in accordance with the terms of the Offer. For purposes of determining the purchase price, those shares that are tendered by the undersigned agreeing to accept the purchase price determined in the Offer will be deemed to be tendered at the minimum price.

☐ The undersigned wants to maximize the chance of having the Company purchase all of the shares the undersigned is tendering (subject to the possibility of proration). Accordingly, by checking this box instead of one of the price boxes above, the undersigned hereby tenders shares at, and is willing to accept, the purchase price determined by the Company in accordance with the terms of the Offer. THE UNDERSIGNED SHOULD UNDERSTAND THAT THIS ELECTION MAY LOWER THE PURCHASE PRICE AND COULD RESULT IN THE TENDERED SHARES BEING PURCHASED AT THE MINIMUM PRICE OF $32.00 PER SHARE.

CHECK ONLY ONE BOX UNDER (1) OR (2) ABOVE. IF MORE THAN ONE BOX IS CHECKED ABOVE, OR IF NO BOX IS CHECKED, THERE IS NO VALID TENDER OF SHARES.

THE GUARANTEE SET FORTH BELOW MUST BE COMPLETED.
