EXHIBIT 1

PURCHASE AGREEMENT

This Purchase Agreement (the “Agreement”) is made as of September 11, 2025 (the “Effective Date”), by and between Matthew T. Moroun, individually (the “Seller”), and the 2020 Irrevocable Lindsay S. Moroun Trust Under Agreement dated November 24, 2020 (the “Buyer”). The Seller and the Buyer are referred to from time to time in this Agreement individually as a “Party” and together as the “Parties.”

Background Recitals

A. The Seller owns certain shares of common stock in PAMT CORP, a Nevada corporation (the “Company”), as described on the attached Exhibit A (the “Subject Shares”).

B. The Company is a publicly traded company listed on NASDAQ under the symbol PAMT.

C. The Seller has obtained an independent third-party opinion on the fair market value of the Subject Shares from Plante & Moran, PLLC (the “Appraiser”) as of the Effective Date (the “Opinion of Value”). The Opinion of Value shall be confirmed in a subsequent written report (the “Appraisal”).

D. The Seller desires to sell to the Buyer all of the Subject Shares, and the Buyer desires to purchase all of the Subject Shares from the Seller, for the fair market value of the Subject Shares determined pursuant to federal gift tax principles, on the terms and subject to the conditions set forth in this Agreement.

E. The Seller has no obligation to sell the Subject Shares to the Buyer, and the Buyer has no obligation to purchase the Subject Shares from the Seller, but after careful consideration of the factors affecting the value thereof, and extensive negotiations between the Parties and their respective advisors, the Parties have agreed on the terms and conditions set forth in this Agreement.

F. The Buyer acknowledges that the Subject Shares may not comprise all of the Seller’s shares of stock in the Company, and that the Seller may retain or subsequently acquire other shares of stock in the Company.

G. The Buyer and the Seller acknowledge that, after careful review, they are each satisfied that the value of the Subject Shares, together with other financial resources that may be available to Buyer, will provide sufficient wherewithal to allow the Buyer to satisfy its obligations pursuant to this Agreement.

H. The Parties acknowledge that they are or may be considered related parties under various provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and that it is specifically intended that the transaction contemplated hereby be at fair market value as ultimately determined for federal gift tax purposes under the provisions of United States Treasury Regulation section 20.2001-1(c).

I. The Buyer acknowledges that it has performed such due diligence as to the Company as the Buyer has deemed appropriate.

Now, therefore, the Parties agree as follows:

Agreement

1. Purchase and Sale of Subject Shares.

(a) On the Closing Date (as defined below), the Seller shall sell, assign, and transfer all of the Subject Shares to the Buyer, free and clear of all liens, security interests, pledges, penalties, forfeitures or encumbrances of any kind, nature or description (“Liens”), for an aggregate purchase price equal to the “Fair Market Value” (defined below) of the Subject Shares on the Effective Date (the “Purchase Price”). The Fair Market Value of the Subject Shares shall be the value on the Effective Date of the Subject Shares as finally determined for federal gift tax purposes pursuant to a Final Determination, as defined in the Purchase Price Addendum to this Agreement attached hereto and made a part hereof (the “Price Addendum”). Neither of the Parties intend that the sale or purchase of the Subject Shares shall constitute a taxable gift for federal gift tax purposes without regard to any deductions provided for in subchapter C or exclusions under sections 2503(b)-(g) of the Code (hereafter, a “Gift”).

(b) The Parties have agreed that the initially determined Purchase Price shall be equal Twenty One Million Four Hundred Ninety Thousand ($21,490,000.00) (the “Initially Determined Purchase Price”).

(c) The Initially Determined Purchase Price was determined after consideration of the Opinion of Value, and after negotiations between the Parties.

(d) The Buyer shall pay the Purchase Price to Seller by issuing a promissory note to the Seller on the Closing Date in the form attached as Exhibit B, which contains the following terms:

(A) The principal amount shall be the Purchase Price. However, as the final Purchase Price may be subject to further adjustment after the Closing as provided in the Price Addendum, the Parties contemplate using a promissory note, subject to revision as provided in this Agreement;

(B) At Closing, the Buyer shall execute a promissory note (the “Initially Determined Purchase Price Note”) that shall reflect the Initially Determined Purchase Price referenced in Section 1(b);

(C) If the Opinion of Value is different than the Appraisal, the Parties agree promptly to revise the Initially Determined Purchase Price Note to reflect the value in the Appraisal. This revised note shall be the updated Initially Determined Purchase Price Note and will reflect the amount of principal due using the updated Initially Determined Purchase Price, after taking into consideration any payments made at Closing and payments under the Initially Determined Purchase Price Note prior to the update.

(D) The Initially Determined Purchase Price Note shall bear the legend “THIS NOTE IS SUBJECT TO REVISION AS PROVIDED IN THE PURCHASE AGREEMENT BETWEEN MAKER AND CREDITOR DATED SEPTEMBER 11, 2025”;

(E) Promptly after the final determination for federal gift tax purposes of the Purchase Price under this Agreement (the “Finally Determined Purchase Price”), if the Finally Determined Purchase Price is different than the Initially Determined Purchase Price, the Parties agree to revise the Purchase Price Note. This revised note (“Finally Determined Purchase Price Note”) will reflect the amount of principal due using the Finally Determined Purchase Price after taking into consideration any payments made after Closing and payments made under a prior Purchase Price Note.

(F) Interest shall accrue on any Purchase Price Note Principal Amount at the rate of three and 97/100 percent (3.97%) per annum, with a default interest rate of two percent per annum in excess of such fixed rate;

(G) Buyer shall pay the Purchase Price Note Principal Amount and the interest thereon as follows: Buyer shall pay monthly installments of interest. The monthly payments are due on the last day of each month, commencing with the first full month after the Closing Date, and all remaining principal, interest, and any other amounts owing under the Purchase Price Note shall be due and payable in full on September 10, 2034 (the “Maturity Date”). If the principal due and accrued interest under a Purchase Price Note is adjusted as a result of a revision in the Purchase Price, then the accrued interest from the adjustment shall be paid within 180 days and the remaining monthly payments of interest under the revised Purchase Price Note shall be adjusted accordingly.

(H) Full or partial pre-payments of any Purchase Price Note Principal Amount shall be permitted without penalty or premium;

(I) The obligations of the Buyer under the Purchase Price Note shall be secured by a grant by the Buyer of a security interest in or pledge of certain accounts, securities, and other assets of the Buyer pursuant to a security agreement, and/or pledge or other agreement in favor of the Seller dated as of the Closing Date in a form acceptable to the Parties (the “Security Agreement”) and such other documents required under the Security Agreement as the Seller may reasonably require from the Buyer, with Buyer further acknowledging that Seller is requiring the Security Agreement to provide for cross-collateralization with the collateral pledged to Buyer pursuant to that certain Pledge Agreement originally dated as of August 1, 2023 and Amended and Restated as of even date hereof, with Buyer as pledgor and Seller as pledgee; and

(J) In the event the Buyer does not cooperate in revising the Initially Determined Purchase Price Note in the manner contemplated above or in the Price Addendum, the Seller shall be entitled to attach to the Initially Determined Purchase Price Note a statement fixing the amount of principal due, and monthly payments, under such note to reflect the Finally Determined Purchase Price and revised monthly payments, as appropriate.

2. Time and Place of Closing. The closing of the purchase and sale of the Subject Shares (the “Closing”) shall take place remotely via the exchange of documents and signatures as soon as practicable following the satisfaction or waiver of the conditions set forth in Section 4. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date,” and the Closing shall be deemed effective at the close of business on the Closing Date.

PURCHASE PRICE ADDENDUM TO PURCHASE AGREEMENT

Capitalized terms as used in this Addendum which are not otherwise defined herein shall have the same meaning assigned to them in the Agreement.

Purchase Price Adjustments.

(a) Initially Determined Purchase Price. The Seller has retained Plante & Moran, PLLC (the “Appraiser”) to appraise the Fair Market Value of the Subject Shares subject to this Agreement as of the Effective Date of this Agreement (the “Initially Determined Purchase Price”). The Appraiser has provided the Opinion of Value and will confirm that Opinion of Value in the Appraisal. If there is a difference between the Fair Market Value of the Subject Shares in the Opinion of Value and the Appraisal, the Purchase Price shall be adjusted, upwards or downwards, to equal the Appraisal. The Seller shall use reasonable best efforts to cause the Appraiser to complete the Appraisal within 60 days following the Effective Date.

(b) Contingent Price Adjustment Upon IRS Audit.

(1) After the Closing Date, the Seller shall timely complete and file with the IRS a United States Gift (and Generation-Skipping Transfer) Tax Return- Form 709 (the “Gift Tax Return”) that will affirmatively report the sale of the Subject Shares under the terms of this Agreement as not being a gift under the provisions of United States Treasury Regulation section 301.6501(c)-1(f)(4). The Seller shall provide the Buyer a draft copy of the proposed Gift Tax Return at least 15 days before filing the Gift Tax Return with the IRS and shall consider in good faith any comments provided by the Buyer or his advisers with respect to the Gift Tax Return. In no event, however, shall the Seller be required to incorporate any of the Buyer’s comments in the Gift Tax Return disclosure.

(2) If at any time after the Closing Date the IRS conducts an audit or other examination to determine whether the sale of the Subject Shares under the terms of this Agreement constitutes a Gift under the provisions of the Code, then the following shall occur.

(A) The Seller shall provide prompt written notice to the Buyer of the commencement of such audit or other examination and, after the execution of an appropriate joint defense or similar agreement protecting attorney-client and other legal privileges, the Seller shall include the Buyer in all aspects of such audit or examination.

(B) The Seller shall use good faith, commercially reasonable efforts to defend the determination of the Initially Determined Purchase Price, and the sales transaction as not constituting a Gift and the terms of the sale of Subject Shares under this Agreement as not being a Gift and to avoid or limit, to the extent reasonably possible, any determination that the sale of Subject Shares under the terms of this Agreement was not for full fair and adequate consideration as of the Closing Date. The Buyer, at its sole cost and expense, shall be entitled to participate in the Seller’s defense.

(3) If it is finally determined pursuant to United States Treasury Regulation section 20.2001-1(c), whether by a non-appealable ruling, order or judgment of a court of competent jurisdiction or by a settlement agreed to by the IRS and the Seller or by some other final and binding agreement of the Seller (“Final Determination”), that the fair market value of the Subject Shares as of the Effective Date is different than the Initially Determined Purchase Price, then:

(A) The Seller shall promptly deliver a copy of the Final Determination to the Buyer and the Finally Determined Purchase Price shall be equal to such fair market value; and

(B) The Seller and the Buyer shall revise the existing Initially Determined Purchase Price Note, and issue the Finally Determined Purchase Price Note in the manner described in section 1(d)(E) of the Agreement. In such an instance, the Parties acknowledge and agree that the Finally Determined Purchase Price Note shall be deemed to exist as of the Closing Date.

(4) If it is finally determined pursuant to United States Treasury Regulation section 20.2001-1(c), whether by a non-appealable ruling, order or judgment of a court of competent jurisdiction or by a settlement agreed to by the IRS and the Seller or by some other final and binding agreement of the Seller (“Final Determination”), that in order to avoid the sale of the Subject Shares from being treated as a gift, whether in whole or in part, that the fair market value of the Subject Shares must be determined as of the Closing Date rather than the Effective Date and the resulting fair market value of the Subject Shares is different than the Initially Determined Purchase Price, then:

(A) The Seller shall promptly deliver a copy of the Final Determination to the Buyer and the Finally Determined Purchase Price shall be equal to such fair market value; and

(B) The Seller and the Buyer shall revise the existing Initially Determined Purchase Price, and issue the Finally Determined Purchase Price Note in the manner described in section 1(d)(E) of the Agreement. In such an instance, the Parties acknowledge and agree that the Finally Determined Purchase Price Note shall be deemed to exist as of the Closing Date.

(5) If either (x) the result of the Final Determination under (3) or (4) above, whichever is applicable, is that the fair market value of the Subject Shares is the same as the Initially Determined Purchase Price or (y) there (i) is no Final Determination, (ii) the statute of limitations applicable to the Gift Tax Return expires (after taking into consideration any extensions or tolling of the statute of limitations), and (iii) there is no pending case in the United States Tax Court or any other federal court between the Seller and the Internal Revenue Service regarding the transactions contemplated in the Purchase Agreement; then:

(A) The Finally Determined Purchase Price shall be equal to the Initially Determined Purchase Price; and

(B) The Seller and the Buyer shall revise the Initially Determined Purchase Price Note, to confirm that such note is the Finally Determined Purchase Price Note.

Purchase Price Note

FORM OF PURCHASE PRICE PROMISSORY NOTE

[ꞏ], 2025

Principal and Interest. For value received, the undersigned, the 2020 Irrevocable Lindsay S. Moroun Trust Under Agreement dated November 24, 2020 (“Maker”), promises to pay to the order of Matthew T. Moroun, an individual (“Creditor”), the principal amount of Twenty One Million Four Hundred Ninety Thousand and 00/100 Dollars ($21,490,000.00) (the “Principal Amount”) for payment of the Purchase Price, as that term is defined under the Purchase Agreement between Maker and Creditor dated September 11, 2025 (the “Purchase Agreement”), and interest on the unpaid Principal Amount at the annual fixed rate equal to [ꞏ]. During the continuance of an Event of Default (as defined below), the interest rate shall increase by 2.00% per annum in excess of the interest rate otherwise applicable until all amounts currently due are paid in full.

Maker shall pay the interest on the Principal Amount of this Note in monthly payments. The initial monthly interest payment amount is $[ꞏ]. The monthly payments are due on the 11th day of each month, commencing with the first month after the Closing Date, and all remaining principal, interest, and any other amounts owing under the Purchase Price Note shall be due and payable in full on [ꞏ], 2034 (the “Maturity Date”). The Principal Amount, and the monthly interest payment amount, shall be subject to adjustment, by revision hereto, in accordance with the Purchase Agreement pursuant to which this Note is issued. If the principal due and accrued interest under this Purchase Price Note is adjusted as a result of a revision in the Purchase Price pursuant to the Purchase Agreement, then the accrued interest resulting from the adjustment shall be paid within 180 days and remaining monthly payments of interest under the revised Purchase Price Note shall be adjusted accordingly.

In the event Maker does not cooperate in adjusting the Principal Amount or monthly payment amount in the manner contemplated in the Purchase Agreement, Creditor shall be entitled to attach to the this Note a statement fixing the amount of principal due under this Note, and revised monthly payment amount, to reflect the Finally Determined Purchase Price, as appropriate and as that term is defined under the Purchase Agreement, as well as the revised monthly payment amount with respect thereto.

Maturity. The entire unpaid Principal Amount and all accrued but unpaid interest on this Note shall be paid in full by the Maturity Date.

Prepayments. Maker may prepay all or part of the amounts due on this Note at any time without premium or penalty. Any partial prepayment will be applied in the manner specified in Section 7 below.

Security. The obligations of Maker to Creditor under this Note are secured by that certain Amended and Restated Pledge Agreement of even date herewith between Maker and Creditor (the “Security Agreement”).

Default. An Event of Default shall occur under this Note if (i) Maker fails to make a payment of interest or principal when due under this Note or fails to pay when due any out-of-pocket expense that Maker owes to the Creditor under this Note and (ii) such default continues for one hundred eighty (180) days after Creditor has given written notice to Maker of the default.

Acceleration. An Acceleration Event shall occur under this Note under each of the following two circumstances. (i) An Acceleration Event shall occur if a default described in section 5(i) continues for two hundred ten (210) days after Creditor has given written notice to the Maker of the default. Such an Acceleration Event shall be referred to as a Payment Acceleration Event. (ii) An Acceleration Event shall also occur on the date, if any, on which the Creditor delivers a notice to Maker that Creditor believes, in good faith, that at such time the prospect of Creditor receiving full payment when due of all amounts owing under this Note is impaired. Such an Acceleration Event shall be referred to as an Impairment Acceleration Event.

B-1

After the occurrence of an Acceleration Event, all of the indebtedness evidenced by this Note and all other obligations then owing by Maker to the Creditor shall become due and payable unless Maker cures the Acceleration Event in the time and manner provided below. The Maker may cure a Payment Acceleration Event by paying all amounts of interest and principal due as of the Payment Acceleration Event within one hundred eighty days (180) days after the date of the Payment Acceleration Event. The Maker may cure an Impairment Acceleration Event within one hundred eighty days (180) days after the Impairment Acceleration Event by making such payments, posting such additional security or collateral, or taking similar actions, so that the Creditor delivers a notice to Maker that Creditor no longer believes, in good faith, that the prospect of Creditor receiving full payment when due of all amounts owing under this Note is impaired.

If a voluntary or involuntary case in bankruptcy, receivership, or insolvency is at any time begun by or against Maker (except an involuntary bankruptcy petition that is dismissed within sixty days of its filing), then all such indebtedness shall automatically become immediately due and payable.

Place and Application of Payments. Each payment on this Note shall be made at Creditor’s address set forth below or any other place that Creditor directs in writing. Any payment on this Note shall be applied in the following order: first, to any expenses (including expenses of collection) then due and payable to Creditor under this Note; second to any accrued and unpaid interest under this Note; and third, to the unpaid principal balance of this Note. If Maker at any time owes Creditor any indebtedness or obligation in addition to the indebtedness evidenced by this Note, and if such other indebtedness owed by Maker to the Creditor is then in default, then Maker shall have no right to direct or designate the particular indebtedness or obligation on which payment made by or collected from Maker shall be applied. Maker waives any such right and agrees that the manner of application of any such payment, as between or among such indebtedness and obligations, shall be determined solely by the Creditor.

Remedies. Creditor shall have all rights and remedies provided by law and by agreement of Maker. Maker shall reimburse Creditor for all expenses, including reasonable attorney fees and legal expenses, that the Creditor pays or incurs in protecting and enforcing the rights of the obligations to Creditor under any provision of this Note and the Security Agreement.

Waivers. No delay by Creditor shall be a waiver of the exercise of any right or remedy. No single or partial exercise by Creditor of any right or remedy shall preclude any other or future exercise of that or any other right or remedy.
