Item 1.01. Entry into a Material Definitive Agreement.

On August 26, 2026, Callan Power LLC, a Nevada limited liability company (“Buyer”) and a subsidiary of Callan JMB Inc. (the “Company”), entered into an Asset Purchase and Sale Agreement (the “APA”) with The Pfanenstiel Company, LLC, an Oklahoma limited liability company (“Seller”), pursuant to which Buyer agreed to acquire fifty percent (50%) of Seller’s right, title and interest in certain oil and gas leases and wells located in North Dakota and Montana (the “Assets”), including leasehold interests, wells, hydrocarbons, equipment, unitization agreements, contracts, surface rights, and related records. Certain wellbores described on Exhibit C to the APA are excluded from the transaction.

The aggregate purchase price for the Assets (the “Purchase Price”) is $12,500,000 in cash, payable at the closing of the transactions (the “Closing”), plus a supplemental payment. The supplemental payment consists of $1,000,000 to be deposited by Buyer into escrow at Closing to pay Buyer’s share of drilling and completion costs for the Assets incurred from the date of execution of the APA through the Closing Date. Any amounts remaining in escrow on the earliest of (i) payment of all of Buyer’s share of such costs or (ii) six months after the Closing Date will be remitted to Seller.

The Closing is expected to occur on or before September 30, 2026 (the “Outside Termination Date”), subject to the satisfaction or waiver of customary closing conditions, including, among others, (i) the accuracy of the representations and warranties of the parties, (ii) the performance of the covenants and agreements of the parties, (iii) the absence of any litigation seeking to prevent the transactions, (iv) Buyer’s satisfactory completion of due diligence on the Assets, (v) Buyer’s receipt of financing on terms acceptable to Buyer, and (vi) delivery of closing deliverables including an assignment, settlement statement, and evidence of bonds posted with governmental authorities.

The APA may be terminated by either party if the Closing has not occurred on or before the Outside Termination Date. Buyer may also terminate if it has not obtained financing satisfactory to Buyer, if it is not satisfied with due diligence results, if there is a material adverse change affecting the Assets, or if required regulatory approvals are not obtained.

Seller makes no warranty of title to the Assets except for a special warranty of title in the Assignment to be delivered at Closing. Except as expressly represented in the APA and the Assignment, Buyer will acquire the Assets on an “as is” and “where is” basis with all faults.

Either party may assign its rights under the APA to a qualified intermediary to accomplish a like-kind exchange under Section 1031 of the Internal Revenue Code. The APA is governed by the laws of the State of Texas, and the parties have waived their respective rights to a jury trial.

The APA contains customary representations, warranties, covenants, and indemnification obligations of the parties. The representations, warranties and covenants contained in the APA were made only for purposes of the APA and as of specific dates, were solely for the benefit of the parties to the APA, and may be subject to limitations agreed upon by the contracting parties.

The foregoing description of the APA does not purport to be complete and is qualified in its entirety by reference to the full text of the APA, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein. Capitalized terms used but not defined in this Current Report on Form 8-K will have the meanings assigned to them by the APA.
