Nature of Operations [Text Block]	Note 1 - Nature of Operations, Basis of Presentation and Going Concern A. Nature of Operations Zion Oil & Gas, Inc., a Texas corporation (“we,” “our,” “Zion” or the “Company”), is an oil and gas exploration company with a history of 25 years of oil & gas exploration in Israel. The shareholders of Zion Oil & Gas, Inc. approved the re-domestication of its incorporation to Texas on June 4, 2025. As of June 30, 2026, the Company has no revenues from its oil and gas operations. Zion maintains its corporate headquarters in Dallas, Texas. The Company also has branch offices in Caesarea, Israel and Geneva, Switzerland. The purpose of the Israel branch is to support the Company’s operations in Israel, and the purpose of the Switzerland branch is to operate a foreign treasury center for the Company. On January 24, 2020, Zion incorporated a wholly owned subsidiary, Zion Drilling, Inc., a Delaware corporation, for the purpose of owning a drilling rig, related equipment and spare parts, and on January 31, 2020, Zion incorporated another wholly owned subsidiary, Zion Drilling Services, Inc., a Delaware corporation, to act as the contractor providing such drilling services. When Zion is not using the rig for its own exploration activities, Zion Drilling Services may contract with other operators in Israel to provide drilling services at market rates then in effect. On May 14, 2025, Zion Drilling, Inc. and Zion Drilling Services, Inc. were re-domesticated and converted from Delaware corporations to Texas corporations pursuant to plans of conversion approved unanimously by the directors and shareholders of each corporation. On October 19, 2022, Zion incorporated a wholly owned subsidiary in Israel, Zion Drilling Israel Ltd, for the purpose of owning a drilling rig and related equipment and spare parts. On this date, the entity was created as a placeholder only. A bank account was created in November 2024 and a tax file was created in January 2025. The bank account is denominated in Israeli Shekels. When there are bank transactions in the future, there will be a translation adjustment to United States Dollars. Zion Drilling Israel Ltd did not have any activities during the six months ended June 30, 2026. Zion has the trademark “ZION DRILLING” filed with the United States Patent and Trademark Office. Zion has the trademark filed with the World Intellectual Property Organization in Geneva, Switzerland, pursuant to the Madrid Agreement and Protocol. In addition, Zion has the trademark filed with the Israeli Trademark Office in Israel. Exploration Rights/Exploration Activities *New Megiddo Valleys License 434* (*“NMVL 434”) – Megiddo-Jezreel #1 Re-Entry (“MJ-01”) On September 14, 2023,* the Israel Ministry of Energy approved NMVL 434, allowing for oil and gas exploration on approximately 75,000 acres or 302 square kilometers. NMVL 434 is valid for three years until September 13, 2026 with four potential 1-year extensions for a total of seven years until September 13, 2030. This NMVL 434 effectively supersedes our previous NML 428. On May, 18, 2026, the Israel Ministry of Energy extended NMVL 434 until September 13, 2027. As of June 10, 2026, field operations commenced for the planned sidetrack phase of the Megiddo-Jezreel #2 well in Israel. As expected, Zion re-entered the well, drilled out the temporary plug, conditioned the wellbore downhole, and has proceeded with the planned horizontal sidetrack drilling. Drilling activities are ongoing as of the date of this report. Additionally, our drilling rig has been recertified and recommissioned in accordance with regulatory requirements, and in a fitting tribute, the rig has officially been renamed JB-1 in honor of Zion’s late founder, John Brown. Note 1 - Nature of Operations, Basis of Presentation and Going Concern (cont’d) B. Basis of Presentation The accompanying unaudited interim consolidated condensed financial statements of Zion Oil & Gas, Inc. have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with Article 8-03 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting only of normal recurring accruals necessary for a fair statement of financial position, results of operations and cash flows, have been included. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the financial statements and the accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The year-end balance sheet data presented for comparative purposes was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results for the year ending December 31, 2026 or for any other subsequent interim period. C. Going Concern The Company incurs cash outflows from operations, and all exploration activities and overhead expenses to date have been financed by way of equity or debt financing. The recoverability of the costs incurred to date is uncertain and dependent upon achieving significant commercial production of hydrocarbons. The Company’s ability to continue as a going concern is dependent upon obtaining the necessary financing to undertake further exploration and development activities and ultimately generating profitable operations from its oil and natural gas interests in the future. The Company’s current operations are dependent upon the adequacy of its current assets to meet its current expenditure requirements and the accuracy of management’s estimates of those requirements. Should those estimates be materially incorrect, the Company’s ability to continue as a going concern may be in doubt. The consolidated condensed financial statements have been prepared on a going concern basis, which contemplates realization of assets and liquidation of liabilities in the ordinary course of business. During the six months ended June 30, 2026, the Company incurred a net loss of approximately $4.1 million and had an accumulated deficit of approximately $306 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the financials were issued. To carry out planned operations, the Company must raise additional funds through additional equity and/or debt issuances or through profitable operations. There can be no assurance that this capital or positive operational income will be available to the Company, and if it is not, the Company may be forced to curtail or cease exploration and development activities. The consolidated condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The accompanying unaudited interim consolidated condensed financial statements of Zion Oil & Gas, Inc. have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with Article 8-03 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements.

The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results for the year ending December 31, 2026 or for any other subsequent interim period.

C. Going Concern

The Company incurs cash outflows from operations, and all exploration activities and overhead expenses to date have been financed by way of equity or debt financing. The recoverability of the costs incurred to date is uncertain and dependent upon achieving significant commercial production of hydrocarbons.

The Company’s ability to continue as a going concern is dependent upon obtaining the necessary financing to undertake further exploration and development activities and ultimately generating profitable operations from its oil and natural gas interests in the future. The Company’s current operations are dependent upon the adequacy of its current assets to meet its current expenditure requirements and the accuracy of management’s estimates of those requirements. Should those estimates be materially incorrect, the Company’s ability to continue as a going concern may be in doubt. The consolidated condensed financial statements have been prepared on a going concern basis, which contemplates realization of assets and liquidation of liabilities in the ordinary course of business. During the six months ended June 30, 2026, the Company incurred a net loss of approximately $4.1 million and had an accumulated deficit of approximately $306 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the financials were issued.

To carry out planned operations, the Company must raise additional funds through additional equity and/or debt issuances or through profitable operations. There can be no assurance that this capital or positive operational income will be available to the Company, and if it is not, the Company may be forced to curtail or cease exploration and development activities.
