Zion Oil & Gas, Inc. filed an amendment to its prospectus supplement on September 10, 2026, regarding its Dividend Reinvestment and Direct Stock Purchase Plan (DSPP). The filing details the extension of a Unit Option program and the execution of a warrant agreement with a third-party agent.

The company announced that the Unit Option program, which began on August 12, 2026, has been extended by the company's sole discretion. Originally scheduled to terminate on September 10, 2026, the program now extends to September 25, 2026.

Under the program, participants may purchase Units priced at $250.00 each. Each Unit consists of a specific number of shares of Common Stock and warrants to purchase an additional seventy-five (75) shares of Common Stock. The number of shares of Common Stock included in a Unit is determined by dividing the $250.00 price by the average of the high and low sale prices of the Company’s publicly traded common stock on the OTCQX on the Unit Purchase Date.

Each warrant is notated as “ZNWBD” and allows the holder to purchase one share of Common Stock at an exercise price of $0.75. The filing states that these warrants will not be registered for trading on the OTCQX or any other stock market. The warrants become exercisable on October 27, 2026, and remain exercisable through April 27, 2027.

The company executed a Warrant Agent Agreement with Equiniti Trust Company, LLC on August 12, 2026. This agreement designates Equiniti Trust Company, LLC as the Warrant Agent for the ZNWBD warrants. The filing includes the Form of Warrant and the Warrant Agent Agreement as exhibits to the report.
