ORGANIZATION AND BUSINESS OPERATIONS	1. ORGANIZATION AND BUSINESS OPERATIONS Global Gas Corporation, a Delaware corporation (the “Company,” “Global Gas”), is a nascent pure-play hydrogen and carbon recovery project developer and industrial gas supplier. Global Gas intends to offer customers reliable, low-carbon and clean hydrogen, pure carbon dioxide, and other gases generated from a variety of feedstocks. Global Gas’ planned activities involve (i) the sourcing, identification, evaluation and vetting of offtake customers seeking to purchase industrial gases, (ii) the securing of local feedstocks, equipment, and utilities, (iii) the planning and management of projects and (iv) the structuring and financing of projects. Global Gas targets both privately- and publicly funded hydrogen development and selected carbon recovery projects, including projects supported by local-, county-, state-, and national-level governments in North America, Western Europe, and Great Britain. Global Gas intends to serve traditional industrial gas customers and is particularly focused on plans to serve the rapidly growing hydrogen-as-energy-carrier market for use in hydrogen fuel-cell powered vehicles. Global Gas’ growth strategy is based on its developing ability to place modular generation, recovery, storage, and dispense solutions in closer geographic proximity to end customers — onsite in many cases — and its developing ability to produce and sell multiple outputs from a single feedstock input.

Specifically, the Company was unable to demonstrate compliance with the Stockholders Equity, Publicly Held Shares, Market Value of Listed Securities and Market Value of Publicly Held Shares requirements set forth in Nasdaq Rule 5505.

The Company was granted until June 20, 2024 to demonstrate compliance with the above-referenced listing rules but was unable to do so by such date. As a result, on June 21, 2024, the Company received notice that the Panel had determined to delist the Company’s securities from Nasdaq and would suspend trading in its securities on the exchange effective at the open of business on June 25, 2024.
